Wherein, the access to M2M user equipment and H2H user equipment under the network element of first network side or business are distinguished Control limits M2M user equipment (can be multiple M2M user equipmenies with identical or different type) in first network side net The lower access of member for example may include: access of all M2M user equipmenies of refusal under the network element of first network side or only receive the One network side element permits the M2M user equipment of access in first network side in the load control strategy about M2M user equipment The access ratio of access or limitation M2M user equipment under the network element of first network side under network element (specifically may be used by the access ratio To be the arbitrary proportion between 0%~100%) or limitation M2M user equipment access rate under the network element of first network side (access rate for example can be 0 time/second, 100 times/second, 500 times/second or other rates) or by being wrapped in broadcast message Containing currently allow or forbid access M2M user equipment MTC Feature or Group ID instruction information, with indicating section Or whole M2M user equipmenies currently allows or forbids accessing first network side network element；M2M user equipment is limited in first network It may include: the ratio for limiting M2M user equipment and transmitting data packet under the network element of first network side that side network element, which carries out business for example, (ratio specifically can be the arbitrary proportion between 0%~100%), or limitation M2M user equipment is in first network side net The lower transmitted per unit time data packet of member maximum number (maximum number for example can for 0 packet/second, 100 packets/second, 500 packets/ Second or other maximum numbers), or connection (such as S1/Iu connection) of the limitation M2M user equipment under the network element of first network side Ratio, or (ratio specifically can be the arbitrary proportion between 0%~100%) limits to M2M use according to set proportion Family equipment distributing paging etc., the limitation M2M user equipment that the present embodiment is not limited to the example above connect under the network element of first network side Enter or carry out the mode of business.

It should be noted that the technical solution of the present embodiment specifically can in mobile management network element or access network elements, Or it is embodied in other equipment.

From the above, it can be seen that M2M user equipment and H2H user equipment in heavy duty network side in the embodiment of the present invention The access of equipment or business carry out difference control, limit M2M user equipment in heavy duty network side equipment and access or carry out industry Business can carry out load control for different M2M application, on the one hand can to avoid or reduce M2M and apply the shadow applied to H2H It rings, advantageously ensures that the normal access or progress business of H2H application, on the other hand advantageously ensure that the normal of special M2M application Access carries out business.

In the embodiment of the present invention, the MTC Feature type of M2M user equipment for example may include: requirement of real-time compared with The weak time tolerates the application of (Time Tolerant) class, requirement of real-time stronger preferential warning message (PAM, priority Alarm message) application or other types of application.

In the embodiment of the present invention, special M2M application can refer to M2M user equipment MTC Feature be PAM application or Other types of application, the Group ID that can be M2M user equipment is application of certain class special identifier etc..

Below by more specifically embodiment, technical solution of the present invention is described in more detail.

Embodiment two,

In the present embodiment, mainly to be more than the threshold value or overload set when the load percentage of mobile management network element M1 When, access network elements A1 carries out difference control to the access of M2M user equipment and H2H user equipment at mobile management network element M1 System, limitation M2M user equipment are accessed in heavy duty mobile management network element M1, are born with realizing to mobile management network element M1 For carrying control, it is specifically described.

Referring to Fig. 3, a kind of load control method of the embodiment of the present invention two, may include:

301, access network elements A1 knows load control strategy of the mobile management network element M1 about M2M user equipment.

Under a kind of application scenarios, mobile management network element M1 can be any after establishing connection with access network elements A1 Moment contains its message about the load control strategy information of M2M user equipment to access network elements A1 transmission, alternatively, Mobile management network element M1 can be in the message for establishing connection with access network elements A1 (for example, S1 establishes response (S1Setup Response) message) in include its load control strategy information about M2M user equipment；Access network elements A1 receives the packet Message of the mobile management network element M1 about the load control strategy information of M2M user equipment is contained, shifting is known from the message Load control strategy of the mobility management network element M1 about M2M user equipment, and the mobile management network that will can further know First M1 is stored about the load control strategy information of M2M user equipment.

In addition, access network elements A1 can certainly know mobile management from other equipment (such as configuration server) Load control strategy of the network element M1 about M2M user equipment；Or mobile management can also be configured in access network elements A1 Load control strategy of the network element M1 about M2M user equipment, access network elements A1 can know mobility directly from being locally configured Load control strategy of the managed network element M1 about M2M user equipment.

Wherein, above-mentioned mobile management network element M1 can be according to specifically answering about the load control strategy of M2M user equipment It is specifically determined with scene.For example, mobile management network element M1 can be base about the load control strategy of M2M user equipment Constructed in M2M user equipment using feature or group identification, under different scenes for different MTC Feature or The load control strategy of the M2M user equipment of Group ID.The load control strategy can specifically include: be set according to M2M user Standby different MTC Feature or Group ID, under the different loads situation of mobile management network element M1 or overload Under, limitation M2M user equipment is linked into mobile management network element M1.

302, access network elements A1 knows the load state of mobile management network element M1.

Under a kind of application scenarios, it includes mobility pipe that mobile management network element M1 can be sent to access network elements A1 The message of network element M1 current load condition information is managed, access network elements A1 receives the message, and knows mobility from the message The load state of managed network element M1.

Under a kind of application scenarios, access network elements A1 knows that the load state of mobile management network element M1 for example can be Know the load state of mobile management network element M1 by knowing the load percentage of mobile management network element M1, or can also be with It is to know the load state of mobile management network element M1 by knowing the instruction of mobile management network element M1 overload.

For example, if access network elements A1 has known the load percentage of mobile management network element M1, can by with set Fixed threshold value is compared, know mobile management network element M1 the grade of load (grade of load may include: slight load, in Degree load, severe load, overload etc.), if having known the instruction of mobile management network element M1 overload, access network elements A1 can be straight It connects and determines that the load state of mobile management network element M1 is overload.

In practical applications, the load state of mobile management network element M1 can be divided into for example slight load, moderate Multiple grades of load such as load, severe load or overload, such as load can be defined as slightly loading lower than 70%, it will be supported on It is defined as intermediate part load between 70% to 80%, will be supported between 80% to 90% and be defined as severe load, it is fixed more than 90% Justice is overload.Mobile management network element M1 for example can be actively or under the triggering of access network elements A1, to access network elements A1 transmission includes the message of mobile management network element M1 percentage load or the grade of load, and access network elements A1 can be from the message In know the load state of mobile management network element M1.

It is understood that mobile management network element M1 can be by increasing field or utilization in existing process messages Newly-increased message notifies its load state to give access network elements A1, while can be by its load about M2M user equipment Control strategy notifies access network elements A1.Mobile management network element M1 can be by one or more message, by its load state It notifies to give access network elements A1, while it can be notified into access network elements A1 about the load control strategy of M2M user equipment.

Or be also possible to when mobile management network element M1 overloads, mobile management network element M1 to access net net First A1 sends overload starting (Overlord Start) message, and instruction mobile management network element M1 is currently at overload；When After mobile management network element M1 overloads, mobile management network element M1, which can send overload to access network elements A1, to be stopped (Overlord Stop) message, to indicate that mobile management network element M1 is currently at non-overloaded state, access network elements A1 then may be used Accordingly, know the load state of mobile management network element M1.Such as the load control strategy about M2M user equipment can be believed Breath is included in the overload initiation message that mobile management network element is sent, and should be believed about the load control strategy of M2M user equipment Breath can be load control strategy information described above, be also possible to the wireless heterogeneous networks that all M2M applications are refused in instruction (RRC, Radio Resource Control) establishment of connection, or instruction only allow the M2M of preferential warning message business to answer With the RRC establishment of connection with urgency traffic.

If 303, the load percentage of mobile management network element M1 has been more than the threshold value or mobile management network element M1 of setting Overload, load control strategy of the access network elements A1 according to mobile management network element M1 about M2M user equipment, limitation M2M are used Family equipment is accessed in mobile management network element M1.

Under a kind of application scenarios, access network elements A1 is to M2M user equipment and H2H user equipment in mobile management network Access under first M1 carries out difference control, and limitation M2M user equipment is accessed in mobile management network element M1 (i.e. to mobile management Network element M1 carries out load control) can include: for access network elements A1 according to mobile management network element M1 load state, refusal is all Access of the M2M user equipment at mobile management network element M1；Alternatively, access network elements A1 is negative according to mobile management network element M1 Load situation receives that the M2M user of access is permitted to set in load control strategy of the mobile management network element M1 about M2M user equipment The standby access at mobile management network element M1；Alternatively, access network elements A1 according to the MTC Feature of M2M user equipment or Group ID and mobile management network element M1 load state, by corresponding percentage limitation M2M user equipment in mobility pipe Manage network element M1 access；Alternatively, access network elements A1 can also according to MTC Feature or the Group ID of M2M user equipment and The load state of mobile management network element M1, the dynamic M2M user equipment that limits in the access rate of mobile management network element M1, It, can be with when the number in the unit time in the M2M user equipment of mobile management network element M1 access has been more than the maximum value of setting Refuse the subsequent M2M user equipment access with identical MTC Feature or Group ID in the unit time.

For example, it is set if mobile management network element M1 is based on M2M user about the load control strategy of M2M user equipment Standby MTC Feature, then the load control strategy of mobile management network element M1 may include: to be for MTC Feature The M2M user equipment of Time Tolerant application disappears if request (RRC connection request) is established in its RRC connection Mobile management network element M1 information is contained in breath, it can be according to the load state of mobile management network element M1, by setting percentage It limits the access of the M2M user equipment of the MTC Feature or limits the access speed of the M2M user equipment of the MTC Feature Rate, if such as mobile management network element M1 slightly load, load control can not be executed, limitation 50% should when intermediate part load The access of the M2M user equipment of MTC Feature or limit its access rate be 500 times/second within, severe load or overload when Request is established in the RRC connection for limiting the M2M user equipment of all MTC Feature；If its RRC connection is established in request message Do not include mobile management network element M1 information, then can be dynamically the MTC according to mobile management network element pool load state The M2M user equipment of Feature selects slight or intermediate part load a mobile management network element, and according to the mobile management The load condition of network element accesses or limits its access speed by the M2M user equipment that setting percentage limits the MTC Feature Rate.Access network elements A1 then can carry out load control to mobile management network element M1 accordingly.

Certainly, the characteristics of applying, being applied according to it for other types of M2M, is respectively set corresponding mobility pipe Manage the load control strategy of the MTC Feature of the network element under different loads situation based on M2M user equipment.

In another example if mobile management network element M1 is based on M2M user equipment about the load control strategy of M2M user equipment Group ID, the load control strategy of mobile management network element M1 can include: be that the special M2M of certain class is used for Group ID Family equipment can be according to mobile management if its RRC connection, which is established in request message, contains mobile management network element M1 information The load state of network element M1 limits the access of the M2M user equipment of the Group ID by setting percentage or limits the Group The access rate of the M2M user equipment of ID, such as do not execute load control when slight load, limitation 20% should when intermediate part load The access of the M2M user equipment of Group ID limits its access rate as within 1000 times/second, severe limits 80% when loading Group ID M2M user equipment access or limitation access rate be within 200 times/second, when overload limit it is all should Request is established in the RRC connection of the M2M user equipment of Group ID；If RRC connection is established in request message not comprising mobility pipe Net element information is managed, then can be dynamically the M2M user equipment of the Group ID according to mobile management network element pool load state A non-overloaded mobile management network element is selected, and according to the mobile management network element load condition, by setting percentage limit It makes the M2M user equipment access of the Group ID or limits the access of its access rate.Access network elements A1 then can be accordingly to movement Property managed network element M1 carries out load control.

Certainly, it for possessing the M2M user equipment of other difference Group ID, can be set according to M2M user under the group Corresponding mobile management network element is respectively set under different loads situation based on the Group of M2M user equipment in standby feature The load control strategy of ID.

Particularly, overload initiation message scene (overload is known from mobile management network element M1 for access network elements A1 Initiation message can include MTC Feature or the Group ID based on M2M user equipment of mobile management network element M1 simultaneously Load control strategy), access network elements A1 can for example refuse in mobile management network element M1 to be that all M2M user equipmenies are built Vertical RRC connection, or only receive the RRC of M2M user equipment urgent business and preferential warning message in mobile management network element M1 Connection etc..That is, mobile management network element M1 can indicate that access network elements A1 refusal is all by overload initiation message The RRC connection that M2M business is established, or only receive urgency traffic and preferential warning message etc..

In the load control for executing mobile management network element, access network elements can know that M2M is used in several ways MTC Feature or the Group id information of family equipment.

For example, it may include this in the RRC connection request message that M2M user equipment is initiated to access network elements A1 MTC Feature or Group id information of M2M user equipment etc., access network elements A1 can be according to the MTC for including in the message Feature or Group id information knows the application feature or group identification of the M2M user equipment.At this point, access network elements A1 Can MTC Feature or Group ID according to mobile management network element M1 based on M2M user equipment load control rule, MTC Feature or the Group ID of the load state of mobile management network element M1 and the M2M user equipment known, limitation The access of M2M user equipment or access rate, and then realize that the load to mobile management network element M1 controls.

Or be also possible to introducing M2M in application, planning the access cell (cell) of M2M application, so that M2M user equipment only accesses access network elements by specific cell (cell), and specific cell can only allow it is specific The M2M user equipment of Group ID accesses.

Concrete methods of realizing, which can be such that, is referred to as M2M Cell for the cell for accessing M2M user equipment, in access net net The mapping relations of M2M cell and specific Group ID are established in member, M2M cell may include this in cell broadcast messages The corresponding Group ID of M2M cell, in this way, M2M user equipment is after receiving cell broadcast messages, if discovery Cell Broadcast CB When Group ID in message is identical with the Group ID of itself, the cell is selected to access.Access network elements can be supported multiple Cell, each Cell distinguish different M2M user equipment accesses using corresponding Group ID, in this way, different cells is wide Broadcast may include the M2M user equipment of different Group ID, different Group ID in message can be according to oneself Group ID selects the corresponding Cell to access, and access network elements according to the Cell that M2M user equipment is accessed and can be locally configured Cell ID and M2M user equipment Group ID map information, know initiate RRC connection establish request M2M user set Standby Group id information.

Particularly, can further access network elements A1 be locally configured M2M user equipment MTC Feature and The map information or wireless access network of Group ID obtained from configuration server M2M user equipment MTC Feature and The map information of Group ID.If the load for the mobile management network element M1 that access network elements A1 is known in step 301 controls Rule is based on Group ID, and it is the MTC Feature information of M2M user equipment that access network elements A1, which is currently known, Then access network elements A1 can be according to MTC Feature and Group ID's that is being locally configured or obtaining from configuration server Map information knows the Group ID of M2M user equipment, carries out load control accordingly.Similar, if access network elements A1 is in step The load control rule for the mobile management network element M1 known in rapid 301 is and the access network elements A1 based on MTC Feature What is currently known is the Group id information of M2M user equipment, then access network elements A1 can be according to being locally configured or from matching The map information for setting MTC Feature and the Group ID obtained in server, knows the MTC Feature of M2M user equipment, Load control is carried out accordingly.

Further, for being not based on MTC Feature or Group about the load control strategy of M2M user equipment When the load control strategy of ID, for example, being again may be by above a variety of based on the load control strategy of all M2M application Mode knows that the M2M application message of instruction M2M user equipment (refers to for example, may include M2M application in RRC connection request message Show that information, or specific cell can only allow the scenes such as M2M user equipment access).

Access network elements A1 executes mobile management network element M1 load control, and can be used according to load control result to M2M Family equipment sends RRC connection and receives (RRC Connection Accept) message or RRC connection refusal (RRC Connection Reject) message is received or is rejected to indicate that M2M user equipment connects.

It is appreciated that being so that access network elements A1 executes the load control of mobile management network element M1 as an example in the present embodiment It is illustrated, naturally it is also possible to by mobile management network element M1 according to the load state of itself and about M2M user equipment Load control strategy carries out load control to itself；Or it can also be by other third party devices to mobile management network element M1 Load control is carried out, load control principle is similar, and details are not described herein again.

Further, the transmission of the data packet of mobile management network element M1 can be limited.When mobile management network element M1 connects The downlink data (Downlink PDU) that such as network side issues is received, mobile management network element M1 can be according to about M2M user The load control strategy of equipment, limitation are negative with the processing for mitigating mobile management network element M1 to M2M user device transmissions data packet Lotus.For example, mobile management network element M1 can be according to MTC Feature or the Group ID and mobility of M2M user equipment Managed network element M1 load state, according to the ratio of the load control strategy setting about M2M user equipment, (ratio specifically can be with The arbitrary proportion between 0%~100%) or according in the unit time of setting data packet transmit maximum number limitation pair The transmission (that is, data packet that mobile management network element M1 does not transmit the M2M user equipment) of M2M customer equipment data packet.Such as, such as The MTC Feature of fruit M2M user equipment is Time Tolerant, then limits the M2M user device transmissions number to this class feature According to packet.

Therefore to be more than the threshold value or overload set when the load percentage of mobile management network element M1 in this implementation When, access network elements A1 carries out area in the business of heavy duty mobile management network element to M2M user equipment and H2H user equipment It does not control, by limitation M2M user equipment in the access of heavy duty mobile management network element, can be directed to and different M2M are answered With load control is carried out, it on the one hand opposite can avoid or reduce M2M using the influence applied to H2H, advantageously ensure that H2H is answered Regular traffic carries out, and on the other hand advantageously ensures that the regular traffic of special M2M application carries out.

Example IV,

In the present embodiment, mainly to access when the load percentage of access network elements A1 is more than the threshold value or overload of setting Network element A1 carries out difference control to the access of M2M user equipment and H2H user equipment at access network elements A1, limits M2M User equipment is accessed in heavy duty access network elements A1, for realizing the load control to access network elements A1, is had Body explanation.

Referring to Fig. 5, a kind of load control method of the embodiment of the present invention four, may include:

501, access network elements A1 knows load control strategy of the access network elements A1 about M2M user equipment.

Under a kind of application scenarios, access network elements A1 can be according to tool about the load control strategy of M2M user equipment Body application scenarios are specifically formulated, for example, can application feature (MTC Feature) based on M2M user equipment or group (Group ID) etc. is identified, its load control strategy about M2M user equipment is constructed.The load control strategy specifically can wrap Include: according to MTC Feature or the Group ID of M2M user equipment, under the different loads situation of access network elements A1 or Under overload, limitation M2M user equipment is linked into access network elements A1.

Access network elements A1 can know access net net from being locally configured or other related equipment (e.g., configuration server) Load control strategy of first A1 about M2M user equipment.

502, access network elements A1 knows the load state or overload of itself.

Under a kind of application scenarios, access network elements A1 knows that the load state of itself for example can be by knowing itself Load percentage know itself load state.

For example, it if access network elements A1 has known the load percentage of itself, can be carried out by the threshold value with setting Compare, know the grade of load of itself (grade of load may include: slight load, intermediate part load, severe load, overload etc.).

In the present embodiment, for example, the load state of access network elements A1 can be divided into for example slight load, moderate is born Multiple grades of load such as load, severe load, overload, such as load can be defined as slightly loading lower than 70%, it will be supported on It is defined as intermediate part load between 70% to 80%, will be supported between 80% to 90% and be defined as severe load, it is fixed more than 90% Justice is overload.

Access network elements A1 can monitor the load state of itself, know itself percentage load or it is corresponding load etc. Grade.

If 503, the load percentage of access network elements A1 has been more than the threshold value or access network elements A1 overload of setting, access Network element A1 connects according to itself load control strategy about M2M user equipment, limitation M2M user equipment in access network elements A1 Enter.

Under a kind of application scenarios, access network elements A1 is to M2M user equipment and H2H user equipment in access network elements A1 Under access carry out difference control, limitation M2M user equipment (is born access network elements A1 in access network elements A1 access Carry control) can include: access network elements A1 refuses all M2M user equipmenies in access network elements A1 according to access network elements A1 Access；Alternatively, load state of the access network elements A1 according to access network elements A1, receives access network elements A1 and uses about M2M Permit access of the M2M user equipment of access at access network elements A1 in the load control strategy of family equipment；Alternatively, access net Network element A1 is pressed and is corresponded to according to MTC Feature or the Group ID and access network elements A1 load state of M2M user equipment Percentage limitation M2M user equipment access network elements A1 access；Alternatively, access network elements A1 can also be according to M2M user The load state of MTC Feature or the Group ID and access network elements A1 of equipment, it is dynamic to limit M2M user equipment In the access rate of access network elements A1, when super in the number of the M2M user equipment of access network elements A1 access in the unit time The maximum value for having crossed setting, can refuse the subsequent M2M user with identical MTC Feature or Group ID in the unit time Equipment access.

For example, if access network elements A1 about M2M user equipment load control strategy based on M2M user equipment MTC Feature, then it is Time that the load control strategy of access network elements A1, which may include: for MTC Feature, The M2M user equipment of Tolerant application, can be according to the load state of access network elements A1, should by setting percentage limitation The access of the M2M user equipment of MTC Feature or limit the MTC Feature M2M user equipment access rate, such as If access network elements A1 is slightly loaded, load control can not be executed, the MTC Feature of limitation 50% when intermediate part load The access of M2M user equipment limits its access rate as within 500 times/second, severe loads or limits all MTC when overloading Request is established in the RRC connection of the M2M user equipment of Feature.Access network elements A1 then can accordingly carry out access network elements A1 Load control.

Certainly, the characteristics of applying, being applied according to it for other types of M2M, is respectively set it in different loads The load control strategy of the MTC Feature under situation or under overload based on M2M user equipment.

In another example if access network elements A1 about M2M user equipment load control strategy based on M2M user equipment Group ID, the load control strategy of access network elements A1 can include: set for the M2M user that it is special that Group ID is certain class It is standby, connecing for the M2M user equipment of the Group ID can be limited by setting percentage according to the load state of access network elements A1 Enter or limit the Group ID M2M user equipment access rate, such as load control is not executed when slight load, moderate is negative Limiting the access of the M2M user equipment of the 20% Group ID when load or limiting its access rate is weight within 1000 times/second The access of the M2M user equipment of the Group ID of limitation 80% or limitation access rate are mistake within 200 times/second when degree load Request is established in the RRC connection that the M2M user equipment of all Group ID is limited when load.Access network elements A1 can then be docked accordingly Network element A1 carries out load control.

In the load control for executing access network elements A1, access network elements A1 can know that M2M is used in several ways MTC Feature or the Group id information of family equipment.

Wherein, access network elements A1 knows the tool that MTC Feature or the Group ID of M2M user equipment believe in this step Body implementation can refer to step 303, and details are not described herein again.

Access network elements A1 executes the load control of itself, and can be sent according to load control result to M2M user equipment RRC connection received message or RRC connection reject message are received or are rejected to indicate that M2M user equipment connects.

It is appreciated that be illustrated so that access network elements A1 executes the load control of itself as an example in the present embodiment, when So can also by other entities according to the load state and access network elements A1 of access network elements A1 about M2M user equipment Load control strategy carries out load control to access network elements A1, and load control principle is similar, and details are not described herein again.

Therefore to connect when the load percentage of access network elements A1 is more than the threshold value or overload of setting in this implementation Network element A1 carries out difference control in the access of access network elements to M2M user equipment and H2H user equipment, and limitation M2M is used Family equipment can carry out load control for different M2M application, on the one hand can keep away in the access of heavy duty access network elements Exempt from or reduce M2M and apply the influence applied to H2H, advantageously ensures that the normal access of H2H application, on the other hand advantageously ensure that The normal access of special M2M application.

Embodiment five,

In the present embodiment, mainly with when the load percentage of access network elements A1 be more than setting threshold value or overload when, to connect Network element A1 carries out difference control to the business of M2M user equipment and H2H user equipment at access network elements A1, limitation Business of the M2M user equipment in heavy duty access network elements A1 carries out, and is to the load control of access network elements A1 with realization Example, is specifically described.

Referring to Fig. 6, a kind of load control method of the embodiment of the present invention five, may include:

601, access network elements A1 knows load control strategy of the access network elements A1 about M2M user equipment.

Wherein, the implementation of step 601 can refer to step 501, and details are not described herein again.

Access network elements A1 can know access network elements from being locally configured or other related equipment (such as configuration server) Load control strategy of the A1 about M2M user equipment.

602, access network elements A1 knows the MTC Feature for being linked into the M2M user equipment of mobile management network element M1 Or Group ID etc..

Wherein, the implementation of step 602 can refer to step 402, and details are not described herein again.

603, access network elements A1 knows the load state of access network elements A1.

Wherein, the specific implementation of step 603 can refer to step 502, and details are not described herein again.

If 604, the load percentage of access network elements A1 has been more than the threshold value or access network elements A1 overload of setting, access Network element A1 limits M2M user equipment access network elements A1's according to itself load control strategy about M2M user equipment Business carries out.

Such as can be, access network elements A1 is according to knowing the load control strategy about M2M user equipment, know The load state of itself and be currently accessed access network elements A1 M2M user equipment MTC Feature or Group ID Information, initiation S1Release or Iu according to the percentage of setting to the M2M user equipment in connected state accessed Release process.

Access network elements A1 can send UE context release request message to mobile management network element M1 or Iu connection is released Request message is put, and can indicate that release cause is access network elements A1 overload.Wherein, for 2G-SGSN, PFM- can be passed through Delete-BSS-PFC.Req deletes BSS message flow context (BSS packet flow context).

Under a kind of application scenarios, access network elements A1 can limit the M2M user equipment of access in access network elements A1 The number of lower transmitted per unit time data packet, when the number of the M2M user equipment transmitted per unit time under access network elements A1 Number according to packet has been more than the maximum value of setting, can abandon the data packet of M2M user equipment subsequent transmission in the unit time；It connects Network element A1 can also load shape according to MTC Feature or the Group ID and access network elements A1 of M2M user equipment Condition is abandoned the data packet of M2M user device transmissions by the percentage of setting.

In addition, access network elements A1 can be according to MTC Feature or the Group ID of M2M user equipment, in access net Under the different loads situation of network element A1, (ratio is specific for the ratio set according to the load control strategy about M2M user equipment Can be the arbitrary proportion between 0%~100%) to RRC Connection Release (the RRC Connection of M2M user equipment transmission Release) message, can indicate the subsequent initiating updating of tracking area immediately/Routing Area Update process of the M2M user equipment, and selection is negative Carry lighter access network elements access.

In addition, under a kind of application scenarios, when access network elements A1 receives paging message, access network elements A1 can be with According to MTC Feature or the Group ID of M2M user equipment, under the different loads situation of access network elements A1, according to pass In the ratio that the load control strategy of M2M user equipment is set, (ratio specifically can be any ratio between 0%~100% Example), limitation initiates paging (Paging) to M2M user equipment, to mitigate the processing load of access network elements A1.

For example, if access network elements A1 about M2M user equipment load control strategy based on M2M user equipment MTC Feature, then it is Time that the load control strategy of access network elements A1, which may include: for MTC Feature, The M2M user equipment of Tolerant application, can limit the MTC Feature's according to the load state of access network elements A1 The number of the data packet of M2M user equipment transmitted per unit time, or the M2M of the MTC Feature is abandoned by setting percentage The data packet of user device transmissions.Such as if access network elements A1 is slightly loaded, and can not execute load control, when intermediate part load Limiting and at most transmitting the number of data packet in the M2M user equipment unit time of the MTC Feature is 500 packets/within the second；Or Person abandons 50% data packet of the M2M user device transmissions of the MTC Feature；All be somebody's turn to do is limited when severe load or overload The data packet of the M2M user equipment of MTC Feature is transmitted, or is initiated to the M2M user equipment of all MTC Feature S1Release/Iu Release discharges corresponding connection.

Certainly, the characteristics of applying, being applied according to it for other types of M2M, is respectively set it in different loads The load control strategy of the MTC Feature under situation based on M2M user equipment.

In another example if access network elements A1 about M2M user equipment load control strategy based on M2M user equipment Group ID, the load control strategy of access network elements A1 can include: set for the M2M user that it is special that Group ID is certain class It is standby, the M2M user equipment transmitted per unit time of the Group ID according to the load state of access network elements A1, can be limited The number of data packet, or the data packet for abandoning the M2M user device transmissions of the Group ID by percentage is set, or initiate to correspond to S1Release/Iu Release of M2M user equipment of the Group ID etc..Such as load control is not executed when slightly loading, The data packet of the M2M user device transmissions of the 20% Group ID is abandoned when intermediate part load or limits its transmitted per unit time The maximum number of data packet is 1000 packets/within the second, and the M2M user equipment that the 80% Group ID is abandoned when severe loads passes Defeated data packet or the maximum number for limiting its transmitted per unit time data packet are 200 packets/within the second, and when overload abandons all The data packet of the transmission of the M2M user equipment of the Group ID, or initiated to the M2M user equipment of the 50% Group ID S1Release/Iu Release。

Therefore in this implementation when the load percentage of access network elements A1 is more than the threshold value or overload of setting, access Network element A1 carries out difference control in the business of access network elements A1 to M2M user equipment and H2H user equipment, and limitation M2M is used Family equipment is carried out in the business of heavy duty access network elements, can be carried out load control for different M2M application, on the one hand may be used The influence applied to H2H is applied to avoid or reduce M2M relatively, advantageously ensures that the regular traffic of H2H application carries out, another party Face advantageously ensures that the regular traffic of special M2M application carries out.

Embodiment six,

It is mainly super in the load for knowing mobile management network element M1 connected to it with access network elements A1 in the present embodiment When crossing the threshold value of setting, access network elements A1 to the access at access network elements A1 of M2M user equipment and H2H user equipment into Row difference control indicates M2M user by sending comprising limitation to M2M user equipment or allowing to access the broadcast message indicated Equipment is limited in access network elements A1 and is accessed, and for realizing the load control to mobile management network element M1, is carried out specifically It is bright.

Referring to Fig. 7, a kind of load control method of the embodiment of the present invention six, may include:

701, access network elements A1 knows load control strategy of the mobile management network element M1 about M2M user equipment.

Wherein, the implementation of step 701 can refer to step 301, and details are not described herein again.

702, access network elements A1 knows the load state of mobile management network element M1.

Wherein, the implementation of step 702 can refer to step 302, and details are not described herein again.

If 703, the load percentage of mobile management network element M1 has been more than the threshold value or mobile management network element M1 of setting Overload, load control strategy of the access network elements A1 according to the mobile management network element M1 known about M2M user equipment, to M2M user equipment sends the instruction message of limitation or the access style allowed, to limit M2M user equipment in access network elements A1 Access.

Under a kind of application scenarios, access network elements A1 can be used according to the mobile management network element M1 known about M2M The load control rule of family equipment or the load state of mobile management network element M1 are controlled in the access of broadcast message Whether instruction currently allows the access of M2M user equipment in (Access Classes) information, or indicates whether to allow certain class The access of the M2M user equipment of MTC Feature or specific Group ID.

For example, if the load percentage of perception mobile management network element M1 has been more than the threshold value of setting, access network elements The instruction that A1 currently can not support M2M user equipment to access in the access control information of the broadcast message issued comprising instruction Information, or the information etc. comprising indicating currently the M2M user equipment of preferential warning message business only to be supported to access.

Particularly, scene (mistake of overload initiation message is known from mobile management network element M1 for access network elements A1 Carry the MTC Feature or Group based on M2M user equipment that initiation message can include mobile management network element M1 simultaneously The load control strategy of ID), access network elements A1 accordingly indicates that mobile management network element M1 is indicated to nothing in broadcast message The load control strategy of line access member A1.That is, by overload initiation message, mobile management network element M1 can be indicated Access network elements A1 indicates to refuse the RRC connection that all M2M business are established in broadcast message, or only receives urgency traffic and excellent First warning message etc..
