The embodiment of the invention discloses a system and equipment for processing contracting-data verification failure. The invention is applied to processing the contracting-data verification failure of the UE in the process of updating location areas, and can ensure that the ISR state between the mobility management entities is kept consistent with that between the mobility management entities and the UE so as to enable an ISR mechanism to be smoothly executed.
Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, a system, and a device for processing a subscription data verification failure.
Background
As shown in fig. 1, a wireless evolution Network architecture in the prior art mainly includes three logic functions, namely, an MME (mobility management Entity), an S-GW (Serving Gateway), and a PDN (Packet Data Network) Gateway. The MME is responsible for functions such as NAS (Network Access Stratum) signaling encryption, roaming, tracking, and the like, and allocates temporary identity, security, and the like of the UE (user equipment), and corresponds to a control plane part of an SGSN (Serving GPRS Support Node) in a current UMTS (Universal Mobile Telecommunications System) System. The S-GW is responsible for a local mobility anchor point, a mobility anchor point in a 3GPP (3rd Generation partnership project) system and related legal monitoring information; the P-GW (PDN Gateway) is responsible for policy enforcement and charging and lawful interception related functions. The SGSN is responsible for the mobility management of 2G/3G and accesses to the evolved core network through an S4 interface.
One requirement of an Evolved Network is to implement an Idle mode signaling Reduction (ISR) function, and reduce mobility management procedures of a User Equipment (UE) in an Idle mode between different Access networks, such as reducing mobility processing of a 3GPP Access system in an Idle state between GERAN (GSM/EDGE Radio Access Network )/UTRAN (UMTS terrestrial Radio Access Network, UMTS terrestrial Radio Access Network) and E-UTRAN (Evolved UMTS terrestrial Radio Access Network). At present, the solution of the ISR mechanism between 3GPP access networks is a dual registration mechanism, i.e. UE registers in two different access networks, and when UE in idle mode moves between the two access networks, the mobility procedure of the 3GPP access system, such as the routing area update/tracking area update procedure between systems, will not be triggered.
Another requirement of the evolved network is to implement a dual Registration (Both Registration) function, reducing the signaling interaction between the mobility management element and the HSS. This mechanism is different from the ISR mechanism. Under the mechanism, the UE is registered in two different access networks, but the UE triggers the mobility process of the 3GPP access system when moving between the two access networks, but the mobility management network elements in the two access networks do not perform signaling interaction with the HSS, so that the signaling interaction between the mobility management network elements and the HSS is reduced.
Under the existing ISR mechanism or dual registration mechanism, after the ISR mechanism is established by two networks, E-UTRAN and GERAN or UTRAN, if the UE moves a new location area (TA and RA, the new location area and the original location area do not necessarily belong to the same mobility management entity), or after the periodic update timer of the location area expires, there may be some other reasons, the UE may initiate the location area update procedure actively.
Under the request of establishing the ISR mechanism or the dual registration mechanism, the location area update procedure generally includes the following three mobility management network elements: the network system comprises a source network element (mobility management network element one), a network element (mobility management network element three) which establishes ISR or double registration with a source, and a target network element (mobility management network element two). If the UE establishes an ISR mechanism or a dual registration mechanism between two network elements, wherein one network element is called as an opposite end network element of the other network element, and the current mobility management network element where the UE is located is the current network element. The mobility management network element is an SGSN network element in a GERAN/UTRAN network and an MME network element in an E-UTRAN network.
In the prior art, the location area update process is as shown in fig. 2, step 4 notifies the network element two of the result of establishing or canceling ISR or double registration, performs subscription data verification in step 6, and performs location area verification (location area verification is also performed according to subscription data) before the mobility management network element two notifies the UE of the location area update result in step 7. Therefore, there may be a case that the network element two in step 4 informs the network element three that the ISR mechanism or the dual registration mechanism is established, but the subscription data verification of the UE fails in step 6 or 7. For this case, the prior art processing method is: the network element returns an Insert Subscriber Data Ack message to the HSS (Home Subscriber server), which carries the area restricted identifier, and the network element two also carries the area restricted identifier in the message rejecting the location update of the UE.
In the process of implementing the invention, the inventor finds that the prior art has the following disadvantages:
under the condition that an ISR mechanism or a double registration mechanism is established between the current mobility management network element and the opposite-end mobility management network element, the UE only informs the HSS and the UE of position limitation in the current mobility management network element, and does not carry out any processing aiming at the ISR or the double registration mechanism and does not inform the opposite-end mobility management network element of any processing. Therefore, the ISR state of the UE in the opposite-end mobility management network element is still the ISR activated state or the UE state is the dual registration state, but the UE sets the ISR state of the UE to the ISR deactivated state or cancels the dual registration of the UE after receiving the UE position limitation notified by the current mobility management network element, and meanwhile, the current mobility management network element separates the UE and does not have the ISR activated state or the dual registration state. Therefore, in the prior art, the ISR state or the dual registration state between two mobility management network elements, and between a mobility management network element and a UE are not consistent, so that the ISR mechanism or the dual registration mechanism cannot be normally executed.

Detailed Description
The embodiment of the invention provides a processing method for signature data verification failure, which comprises the following steps:
step 101, determining that the subscription data verification fails in the location updating process. Wherein the failure of the subscription data validation comprises: the subscription data (such as APN and the like) of the UE is incorrect, the subscription location area of the UE is limited, the access of the UE is limited (such as access technology limit) and the like.
Step 102, instructing the opposite terminal mobility management network element to separate the UE. Directly informing a mobility management network element of an opposite terminal to delete the context (including the mobility management context and the bearing context) of the UE through an indication message; or sending an indication message to a serving gateway (S-GW), so that the S-GW sends the indication message to an opposite-end mobility management network element and indicates the opposite-end mobility management network element to delete the context of the UE; or sending an indication message to a Home Subscriber Server (HSS) to indicate the HSS to send a delete position message to an opposite terminal mobility management network element, so that the opposite terminal mobility management network element deletes the context of the UE. Or,
directly informing an opposite terminal mobility management network element to cancel the association of the UE between the current network and an opposite terminal network through an indication message, but keeping the context of the UE; or sending an indication message to an S-GW, so that the S-GW sends the indication message to the opposite-end mobility management network element, and the opposite-end mobility management network element is indicated to cancel the association of the UE between the current network and the opposite-end network but retain the context of the UE.
In an embodiment of the present invention, as shown in fig. 3, a method for processing a failure of verifying location subscription data of a UE includes the following steps:
step 301, after the current mobility management network element finds that the verification of the subscription data fails, it is determined that the current mobility management network element has already notified the opposite-end mobility management network element to enable the ISR mechanism or the dual registration mechanism.
Step 302, the current mobility management network element notifies the opposite mobility management network element to separate the UE. If the current mobility management network element sends a separation indication message or a separation request message to the opposite-end mobility management network element.
Step 303, after receiving the above message, the mobility management network element at the opposite end interacts information with the S-GW, deletes the bearer context of the UE, and separates the UE from the mobility management network element.
Step 304, the current mobility management network element and the S-GW exchange information, and the bearing context of the UE is deleted. The order of occurrence of step 303 and step 304 is not limited.
Step 305, after receiving the bearer context deletion message of the current mobility management network element and the opposite-end mobility management network element, the S-GW interacts information with the P-GW and deletes the bearer context of the UE.
Step 306, the current Mobility Management network element deletes the bearer context and Mobility Management (MM) context of the UE.
Step 307, the current mobility management network element rejects the location area update and sends a location update reject message (for GERAN/UTRAN network this message is a routing area update reject message; for E-UTRAN network this message is a tracking area update reject message) to the UE. For this embodiment, the cause value of the rejection is "failure of verification of subscription data of the UE" or "limited access of the UE" or "limited location area". In this embodiment, the UE deletes the context information of the UE after receiving the message.
In the second embodiment of the present invention, as shown in fig. 4, a method for processing failure of verification of UE location subscription data includes the following steps:
step 401, after the current mobility management network element finds that the verification of the subscription data fails, it is determined that the current mobility management network element has already notified the opposite-end mobility management network element to enable the ISR mechanism or the dual registration mechanism.
Step 402, the current mobility management network element and the S-GW exchange information, and the bearing context of the UE is deleted. In a bearing deletion request message sent by a current mobility management network element to an S-GW, the current mobility management network element carries indication information to indicate the S-GW to delete the bearing context of an opposite-end mobility management network element. The indication information may specifically be:
1) and the current mobility management network element carries a 'Cause' cell in the bearer deletion request message. The current mobility management network element sets the cell as 'UE subscription data authentication failure' or 'UE access limitation' or 'location area limitation' to inform the S-GW that the bearer deletion request is caused by the UE subscription data authentication failure.
2) And the current mobility management network element carries an ISR Deactivationindicator indication bit cell or a Both Registration Cancel Indicator indication bit cell in the bearing deletion request message.
3) And the current mobility management network element carries an ISR Flag bit or a Both Registration Flag cell in the bearer deletion request message. The current mobility management network element sets the information element to 'flag' or '0' to indicate that the ISR of the S-GW UE is deactivated or that dual registration is cancelled.
Alternatively, step 405 may occur after step 402 occurs.
Step 403, after deleting the signaling connection with the current mobility management network element after the S-GW receives the message, interacting information with the opposite-end mobility management network element, and notifying the deletion of the bearer context of the UE. The S-GW sends a bearer deletion request message to the peer mobility management network element, which may carry indication information to indicate the peer mobility management network element to separate the UE. The indication information may specifically be:
1) and the S-GW carries a 'Cause' cell in the bearing deletion request message. The S-GW sets the cell as 'UE subscription data verification failure' or 'UE access limitation' or 'location area limitation' so as to inform an opposite terminal mobility management network element that the bearer deletion request is caused by the UE subscription data verification failure.
2) And the S-GW carries an indication bit cell of 'ISR Deactivationindicator' or an indication bit cell of 'Both Registration Cancel Indicator' in the bearing deletion request message.
3) And the S-GW carries an ISR Flag bit or a Bothregistration Flag cell in the bearing deletion request message. The S-GW sets the cell to "Flase" or "0" to indicate that ISR of the peer mobility management network element UE is deactivated or that dual registration is cancelled.
And after receiving the message, the opposite terminal mobility management network element deletes the mobility management context of the UE and separates the UE.
Step 404, after deleting the signaling connection with the two mobility management network elements, the S-GW interacts information with the P-GW and deletes the bearer context of the UE.
Step 405, the current mobility management network element deletes the bearer context and the mobility management context of the UE.
In step 406, the current mobility management network element rejects the location area update and sends a location update reject message (for GERAN/UTRAN network, this message is a routing area update reject message; for E-UTRAN network, this message is a tracking area update reject message) to the UE. For this embodiment, the cause value of the rejection is "failure of verification of subscription data of the UE" or "limited access of the UE" or "limited location area". In this embodiment, the UE deletes the context information of the UE after receiving the message.
In the third embodiment of the present invention, as shown in fig. 5, a method for processing a failure of verifying location subscription data of a UE includes the following steps:
step 501, after the current mobility management network element finds that the verification of the subscription data fails, it is judged that the current mobility management network element has already notified the opposite-end mobility management network element to enable the ISR mechanism or the dual registration mechanism.
In step 502, the current mobility management element replies an indication message (i.e. an Insert subscription Data acknowledgement message Insert Subscriber Data Ack) to the HSS, where the indication message is carried to indicate that the HSS subscription Data authentication fails. The indication information may specifically be:
the current mobility management network element carries a "Cause" cell in the insertion subscription data acknowledgement message. The current mobility management network element sets the cell as 'UE subscription data authentication failure' or 'UE access limitation' or 'location area limitation' to inform HSS of the UE subscription data authentication failure.
Alternatively, step 507 may occur after step 502 occurs.
Step 503, after receiving the above message, the HSS interacts information with the opposite terminal mobility management network element, and deletes the context of the UE on the opposite terminal mobility management network element.
Step 504, the opposite terminal mobility management network element and the S-GW exchange information, and delete the bearer context of the UE.
Step 505, the current mobility management network element and the S-GW exchange information, and delete the bearer context of the UE.
Step 506, after receiving the deletion message of the current mobility management network element and the opposite-end mobility management network element, the S-GW interacts information with the P-GW and deletes the bearer context of the UE.
In step 507, the current mobility management network element deletes the bearer context and the mobility management context of the UE.
Step 508, the current mobility management network element rejects the location area update and sends a location update reject message (for GERAN/UTRAN network this message is a routing area update reject message; for E-UTRAN network this message is a tracking area update reject message) to the UE. For this embodiment, the cause value of the rejection is "failure of verification of subscription data of the UE" or "limited access of the UE" or "limited location area". In this embodiment, the UE deletes the context information of the UE after receiving the message.
In the fourth embodiment of the present invention, as shown in fig. 6, a method for processing a failure of verifying location subscription data of a UE includes the following steps:
step 601, after the current mobility management network element finds that the verification of the subscription data fails, it is judged that the current mobility management network element has already notified the opposite network element to enable the ISR mechanism or the dual registration mechanism.
In step 602, the current mobility management network element sends indication information to the peer mobility management network element, which indicates the peer mobility management network element to cancel an ISR mechanism (No ISR) or a dual registration mechanism, but keeps the context of the UE. The indication information may specifically be:
1) an ISR deactivation indication message, or an ISR deactivation request message. The current mobility management network element instructs the opposite mobility management network element to cancel the ISR mechanism through the message, but the context of the UE is preserved. The current mobility management network element may carry a "Cause" cell in the message, and the current mobility management network element sets the cell as "UE subscription data verification failure" or "UE access restricted" or "location area restricted" to notify the opposite mobility management network element that ISR deactivation of the UE is due to the UE subscription data verification failure.
2) A dual registration cancellation indication message or a dual registration cancellation request message. The current mobility management network element instructs the opposite mobility management network element to cancel the dual registration mechanism through the message, but the context of the UE is preserved. The current mobility management network element may carry a "Cause" cell in the message, and the current mobility management network element sets the cell as "UE subscription data authentication failed" or "UE access restricted" or "location area restricted" to notify the opposite mobility management network element that the dual registration cancellation of the UE is due to the UE subscription data authentication failure.
After receiving the message, the opposite terminal mobility management network element sets the ISR state of the UE as a deactivation state or cancels the double registration of the UE, but keeps the context of the UE.
Step 603, the current mobility management network element and the S-GW exchange information, and delete the bearer context of the UE.
In step 604, the current mobility management network element deletes the bearer context and the mobility management context of the UE.
Step 605, the current mobility management network element rejects the location area update and sends a location update reject message (for GERAN/UTRAN network, this message is a routing area update reject message; for E-UTRAN network, this message is a tracking area update reject message) to the UE. For this embodiment, the cause value of the rejection is "failure of verification of subscription data of the UE" or "limited access of the UE" or "limited location area". In the reject message, if the current mobility management network element determines that the UE has enabled the ISR mechanism or the dual registration mechanism before the location area update, the current mobility management network element may carry indication information indicating that the UE retains context information of the UE in the source network. The indication information may specifically be:
1) and a "UE Information Reserved Indicator" Information element.
2) And a "UE Information Reserved Flag" Information element. The current mobility management network element sets this information element to "True" or to "1" to indicate that the context information of the UE in the source network needs to be preserved.
Of course, the UE may not have the cause value, and after receiving the location update reject message, if the UE finds that the reject is caused by the failure of the subscription data verification, the UE retains the context information in the source network.
In the fifth embodiment of the present invention, as shown in fig. 7, a method for processing a failure of verifying location subscription data of a UE includes the following steps:
step 701, after the current mobility management network element finds that the verification of the subscription data fails, it is determined that the current mobility management network element has already notified the opposite-end mobility management network element to enable the ISR mechanism or the dual registration mechanism.
Step 702, the current mobility management network element and the S-GW interactively delete the bearer context for use. In the bearer deletion request message sent by the current mobility management network element to the S-GW, the current mobility management network element may carry an indication information to indicate the S-GW to notify the opposite-end mobility management network element to cancel the ISR or to request to retain the context information though the dual registration mechanism. The indication information may specifically be:
1) and the current mobility management network element carries a 'Cause' cell in the bearer deletion request message. The current mobility management network element sets the cell as 'UE subscription data authentication failure' or 'UE access limitation' or 'location area limitation' to inform the S-GW that the bearer deletion request is caused by the UE subscription data authentication failure.
2) And the current mobility management network element carries an ISR Deactivationindicator indication bit cell or a Both Registration Cancel Indicator indication bit cell in the bearing deletion request message.
3) And the current mobility management network element carries an ISR Flag bit or a Both Registration Flag bit cell in the bearer deletion request message. The current mobility management network element sets the cell to 'Flase' or '0' to indicate that ISR of the S-GW UE is deactivated or cancel dual registration of the UE.
Additionally, step 804 may occur after step 802 occurs.
Step 703, after receiving the above message, the S-GW instructs the peer mobility management network element to cancel isr (noisr) or dual registration, but keeps the upper and lower bits of the UE. The indication may specifically be:
1) an ISR deactivation indication message, or an ISR deactivation request message. The S-GW instructs the correspondent mobility management network element to cancel the ISR mechanism through this message, but retains the context of the UE. The S-GW may carry a "Cause" cell in the message, and the S-GW sets the cell to "UE subscription data verification failure" or "UE access restricted" or "location area restricted" to notify the opposite terminal mobility management network element that ISR deactivation of the UE is due to the UE subscription data verification failure. After receiving the message, the opposite terminal mobility management network element sets the ISR state of the UE to be a deactivation state, but keeps the context of the UE.
2) A dual registration cancellation indication message or a dual registration cancellation request message. The S-GW instructs the correspondent mobility management network element to cancel the dual registration mechanism through this message, but retains the context of the UE. The S-GW may carry a "Cause" cell in the message, and the S-GW sets the cell to "UE subscription data authentication failure" or "UE access restricted" or "location area restricted" to notify that the dual registration cancellation of the peer mobility management network element UE is due to the UE subscription data authentication failure.
Step 704, the current mobility management network element deletes the bearer context and the mobility management context of the UE.
Step 705, the current mobility management network element rejects the location area update and sends a location update reject message (for GERAN/UTRAN network, this message is a routing area update reject message; for E-UTRAN network, this message is a tracking area update reject message) to the UE. For this embodiment, the cause value of the rejection is "failure of verification of subscription data of the UE" or "limited access of the UE" or "limited location area". In the reject message, if the current mobility management network element determines that the UE has enabled the ISR mechanism or the dual registration mechanism before the location area update, the current mobility management network element may carry indication information indicating that the UE retains context information of the UE in the source network. The indication information may specifically be:
1) and a "UE Information Reserved Indicator" Information element.
2) And a "UE Information Reserved Flag" Information element. The current mobility management network element sets this information element to "True" or to "1" to indicate that the context information of the UE in the source network needs to be preserved.
Of course, the UE may not have the cause value, and after receiving the location update reject message, if the UE finds that the reject is caused by the failure of the subscription data verification, the UE retains the context information in the source network.
In the sixth embodiment of the present invention, as shown in fig. 8, a method for processing a failure of verifying location subscription data of a UE includes the following steps:
step 801, after the current mobility management element finds that the verification of the subscription data fails, it is determined that the current mobility management element has notified the opposite mobility management element not to enable the ISR mechanism or the dual registration mechanism, but finds that the UE starts the ISR mechanism or the dual registration mechanism before the location area is updated.
Step 802, the current mobility management network element and the S-GW exchange information, and delete the bearer context of the UE.
Step 803, the current mobility management network element deletes the bearer context and the mobility management context of the UE.
Step 804, the current mobility management network element rejects the location area update and sends a location update reject message (for GERAN/UTRAN network, this message is a routing area update reject message; for E-UTRAN network, this message is a tracking area update reject message) to the UE. For this embodiment, the cause value of the rejection is "failure of verification of subscription data of the UE" or "limited access of the UE" or "limited location area". In this embodiment, the UE deletes the UE context information after receiving the message.
