The parameters such as the position of point and intermediate node, quantity, nodal properties, passback specification；
Passback node includes destination node and intermediate node, and wherein destination node is return data and access net service centre
Between interface, intermediate node be in return path carry out return data relay transmission node.Due to wired backhaul lines
Feature (such as channel reliability is high, capacity is big, time delay is small), destination node is usually real by the node with wired passback ability
It is existing.In UDN deployment, the availability of wired passback depends on the physical limit of specific site.Carrying out return network design
When, it is first determined it can get position and the network structure of wired passback, it is then further true according to network structure and service distribution
Determine the parameters such as position, quantity, nodal properties, the passback specification of destination node and intermediate node.By to passback node management,
While guaranteeing return data transmission service, the efficiency of operation and ability of return network is effectively promoted.
The passback nodal information tableau format of access net service centre's chain of command maintenance is as shown in table 1.
Table 1 returns informational table of nodes
2, the management and optimization function of return network topology
Return network Topology Management and optimization function are mainly accomplished that: determining its purpose section for each wireless backhaul small station
Point, and determine to the path of its destination node and institute through intermediate node, while considering that multiple network performance indicator (such as is always handled up
Amount, the guarantee of service quality (QoS) grade etc.), so that network topology and path is adapted to the variation of service distribution.
Because the wireless portion in return network forms a mesh network (such as wireless Mesh netword).With wireless backhaul ability
Small station need adjacent area assist relay transmission return data, select suitable return path be the key that determine passback performance because
Element.Wireless backhaul topology and return path need to carry out dynamic pipe according to the DYNAMIC DISTRIBUTION and QoS requirement of business in network
Reason and optimization.Return network Topology Management and optimization function are that each wireless backhaul small station determines its destination node, and determination is arrived
The path of its destination node and institute are through intermediate node, to liberally provide data back clothes as far as possible for all wireless small stations
Business.Meanwhile needing to consider multiple network performance indicator, for example, native region priority, total throughput and service quality rating guarantee.
By return network Topology Management and optimization function, on larger time granularity (for example, a couple of days, a few hours) make network topology and
Path adapts to the variation of service distribution, effectively promotes the performance and efficiency of wireless backhaul network.
For example, AP5 be plug and play AP, when it be switched on access network after, access net service centre's chain of command according to time
It passes informational table of nodes and its business demand (such as handling capacity 200Mbps, time delay < 50ms etc.) is that its automatic establishes returns road
Diameter<AP1 (1Gbps,<1ms)-AP4 (500Mbps,<5ms)-AP5 (200Mbps,<50ms)>.When nodal information changes (example
As AP2 open) and/or business demand change (such as handling capacity increases to 600Mbps) when, access net service centre management
Face is that it selects new return path<AP2 (1Gbps,<1ms)-AP5 (600Mbps,<50ms)>, the wherein jump of return path
Number is reduced (level of source node reduces), and passback handling capacity increases, and return path is optimized.
3, the management and optimization function of return network resource
Based on currently determining wireless backhaul network topology and return path, progress radio resource allocation (such as the frequency that works
Point, distribution of bandwidth etc.), so that Internet resources is adapted to the variation of data transmission, effectively promotes the efficiency of wireless backhaul Internet resources
And transmission performance.
Based on currently determining wireless backhaul network topology and return path, pass through wireless backhaul resource allocation and link tune
Degree realizes the transmission of small station return data.Return network resource management and optimization function are carried out as unit of Radio Link.Passback
Relaying small station in network may service multiple downstream small stations simultaneously, it is also possible to multiple small stations upstream small station having the same.
According to each small station itself return data queue and relaying data queue, dispatches corresponding small station and link and sent out in corresponding time slot
Return data is sent, to meet business service quality requirement.By return network resource management and optimization function, in the smaller time
(for example, several minutes, several seconds) makes Internet resources adapt to the variation of data transmission in granularity, effectively promotes wireless backhaul Internet resources
Efficiency and transmission performance.
For example, the frequency point that AP5 is supported is f2, f3, for the return path that its booting is established, the management of access net service centre
Frequency point f2, f4 that face is supported according to passback informational table of nodes middle and upper reaches small station AP4, the working frequency points f2 of return link is distributed for it
With the working frequency points f3 of access link.After return path change, access net service centre's chain of command is it and upstream small station AP2
Between return link share out the work frequency point f3, share out the work frequency point f2 for its access link.
The self-configuring process of return network in distributed networking are as follows:
In distributed networking, no centralized node, access net service centre's chain of command carries out the self-configuring of return network, such as
Shown in Fig. 6, the solid line link in Fig. 6 is existing return link, and dotted line link is newly-built return link, between terminal and small station
Link is access link.Wherein, macro station deploys wired passback, and small station is wireless backhaul, from deployment or plug and play, small station
Return path can be established with small station around, macro station.
As shown in fig. 7, distributed group is off the net, the interactive process of each node is main in network are as follows:
Step 71: access net service centre's chain of command is managed passback node, maintenance passback informational table of nodes.Passback
The information of node includes location information, ability information, status information, back information etc..
The step 71 is mainly realized by passback node administration function.
The information for returning node can dispose initial stage acquisition by network, i.e. network deployment initial stage nets service centre in access
The information of record passback node；Acquisition can also be reported by nodal information, that is, returns node for the location information of oneself, ability
Information, status information, back information etc. are reported to access net service centre.
For example, for the distributed networking in Fig. 6, in the passback informational table of nodes of access net service centre's chain of command maintenance
Particular content it is as shown in table 2, wherein in the passback informational table of nodes include macro station, the information of AP2, AP3 and AP5.
The access net service centre's chain of command of table 2 is directed to the passback informational table of nodes of Fig. 6 maintenance
Meanwhile it is as shown in table 3 to access the net existing return path of service centre's chain of command:
Already present return path in Fig. 6 of the access net service centre's chain of command record of table 3
Wherein, AP2 is the return path of 1 single-hop, and AP3 is the return path of 12 jump, and AP5 is that 2 return paths are (single
It jumps and 2 jumps return path).AP2 has 1 upstream node, 2 downstream nodes；AP3 has 1 upstream node, without downstream node；
AP5 has 2 upstream nodes, without downstream node.
Step 72: after wireless small station (AP1, AP4, AP6, AP7) booting, in frequency point (including macro station and/or the small station of support
Frequency point) on carry out nearby region measurement.
For example, the frequency point that AP1 is supported includes 2.0GHz, 3.4GHz-3.6GHz.Meanwhile the macro station work of surrounding exists
The AP of 2.0GHz, surrounding work in 3.5GHz.So, AP1 carries out nearby region measurement, and the reference signal for obtaining surrounding macro station and AP connects
Power (RSRP) measurement result is received, the RSRP of macro station is -80dBm, and the RSRP of AP2 is -90dBm, and the RSRP of AP3 is -110dBm.
Step 73: wireless small station sends access network request to access net service centre's chain of command, and the ability comprising it is believed
Breath, business demand, nearby region measurement result etc..
For example, AP1 selects the maximum node macro station of RSRP, after carrying out random access, access network is sent by RRC information
Request, the frequency point comprising support are { f1, f2 }, and handling capacity is 200Mbps in passback demand, on each frequency point of nearby region measurement result
The access network request of the AP1 is transmitted to access net service centre by disturbed condition (the sum of such as RSRP) f1 > f2, macro station.
Step 74: access net service centre's chain of command is according to the access network request in wireless small station and the passback section of maintenance
Point information table selects suitable return path newly to access wireless small station, includes source node, destination node and institute in return path
The intermediate node of warp.
It should be noted that the step 74 is mainly realized by return network Topology Management and optimization function.
For example, the level of macro station is 0, the frequency point of support is { f1 }, and the handling capacity for having return link is 1Gbps, time delay
Less than 1ms.Access net service centre's chain of command carries out return link judgement, because of 1000 > 200+delta (delta=10Mbps),
It can satisfy the passback demand of AP1, can be the frequency point that AP1 establishes return link be f1, therefore, access net service centre pipe
Reason face is that AP1 selects return path<macro station-AP1>.
It should be noted that delta is the handling capacity surplus of setting, for preventing certain traffic fluctuations from influencing.
Step 75: the service centre's management of access net configures message towards wireless small station and passback node transmitting path, wherein
After accessing network comprising wireless small station, the routing information of the return path of foundation.
In addition, return path is updated to state as shown in table 4 by access net service centre's chain of command:
When wireless small station is newly added in 4 Fig. 6 of table, updated return path
Step 76: access net service centre's chain of command is based on the newly-established return path in wireless small station, according to wireless small station
Access network request and maintenance passback informational table of nodes, be the return link newly accessed on the return path in wireless small station
Distributing radio resource, and be the access link distributing radio resource in wireless small station, the radio resource of distribution include working frequency points,
Bandwidth etc..
It should be noted that the step 76 is mainly realized by return network resource management and optimization function.
For example, the frequency point that macro station is supported is { f1 }, what AP1 was supported based on the return path<macro station-AP1>that AP1 is created
Frequency point is { f1, f2 }, and the intersection of the two is f1.Although nearby region measurement result is the disturbed condition (the sum of such as RSRP) on each frequency point
F1 > f2, but the frequency point of return link is only f1 between macro station and AP1.Therefore, access net service centre's chain of command is AP1
Select the frequency point on return link for f1.Since AP1 also supports frequency point f2, while the interference on f2 is smaller, so access net clothes
Business centre management face is that AP1 selects the frequency point on access link for f2.
Step 77: the service centre's management of access net sends resource distribution message towards wireless small station and passback node, wherein
After accessing network comprising wireless small station, the nothing of the radio resource of each return link and wireless small station access link in return path
Line resource, radio resource include working frequency points, bandwidth etc..
Further, access nets service centre's chain of command while for wireless small station selection newly-built return path,
It is assigned with radio resource.Therefore, path configuration message and resource distribution message can be sent in a signaling, such as wireless small
It stands and configures message, wherein the return link and access chain of routing information and distribution comprising the newly-built return path in wireless small station
The radio resource on road.
For example, the configuration message of AP1 be<macro station (f1)-(f1,200Mbps)-AP1 (f2)>.
Step 78: after wireless small station receives path configuration message and resource distribution message, needing to establish with upstream node
Return link carries out the preparation of normal work.Meanwhile after passback node receives path configuration message and resource distribution message, need
Return link is established with downstream node, carry out and the preparation of wireless backhaul service is provided.
For example, AP1 and macro station establish return link, AP1 opens the frequency point f1 and access link frequency point f2 of return link,
Business datum of the macro station on the return link between AP1 reserves bandwidth, and carries out scheduling of resource.
Because the interactive process of hybridized group each node off the net is similar with the interactive process of distributed networking, no longer carry out herein
Detailed description.
Example IV
As shown in figure 8, the management method of the embodiment of the present invention return network, comprising:
Step 81, access network request when network is added in wireless small station is obtained；
Step 82, passback informational table of nodes is obtained；
Step 83, according to the access network request and passback informational table of nodes, for the wireless small station distribution first
Return configuration information；
Step 84, the first passback configuration information is sent to the wireless small station, so that the wireless small station is according to institute
It states the first passback configuration information and establishes corresponding return link；
It step 85, will be described in the triggering message of the first passback configuration information change for getting the wireless small station
First passback configuration information is changed to the second passback configuration information；
It should be noted that the information that the triggering message includes the passback node in passback informational table of nodes changes
And/or the business demand in the wireless small station changes.
Step 86, the second passback configuration information is sent to the wireless small station, so that the wireless small station is according to institute
It states the second passback configuration information and establishes corresponding return link.
In the present embodiment, according to network state information, the return path in wireless small station is adjusted in real time, ensure that
Wireless small station can in the changeable network of state steady operation.
Be directed to above-described embodiment, the self-optimizing process of the return network off the net to hybridized group be specifically described as
Under.
In hybrid networking, by access net service center controls, (centralized node function is put into access net clothes for a part of base station
Business center), another part base station carries out the self-optimizing of return network, such as Fig. 9 without centralized node, access net service centre's chain of command
Shown, the solid line link in Fig. 9 is existing return link, and dotted line link is optimization return link, the chain between terminal and small station
Road is access link.Wherein, for AP1 and AP2 by access net service center controls, they are wired between access net service centre
Passback, can carry out the transmission of data and signaling.Wire link (such as X2 mouthfuls) is established between macro station and access net service centre, it can
To carry out the interaction of data and signaling.AP3, AP4 and AP5 are the AP of plug and play, and are distributed group net mode, AP3 and macro
Wireless backhaul is established between standing, macro station provides backhaul service for it.Wireless backhaul is established between AP4 and AP1, AP1 is it
Backhaul service is provided.After AP5 booting, access net service centre's chain of command is that it establishes return path and distribution passback resource.
As shown in Figure 10, hybridized group is off the net, and network returns the interaction flow of each node during self-optimizing are as follows:
Step 101: access net service centre's chain of command is managed passback node, maintenance passback informational table of nodes.When
When nodal information changes, access net service centre's chain of command updates passback informational table of nodes.Nodal information changes packet
The location information for including passback node changes (such as node motion or coordinate change), and status information changes (example
As open become close or close become to open), back information change (such as passback handling capacity, level increase or subtract
It is few) etc..
For example, for the hybrid networking in Fig. 9, in the passback informational table of nodes of access net service centre's chain of command maintenance
Particular content it is as shown in table 5, wherein in the passback informational table of nodes comprising macro station, AP1, AP2, AP3, AP4 and AP5 letter
Breath.
The access net service centre's chain of command of table 5 is directed to the passback informational table of nodes of Fig. 9 record
Meanwhile it is as shown in table 6 to access the net existing return path of service centre's chain of command:
The access net service centre's chain of command of table 6 is directed to the already present return path of Fig. 9 record
After AP2 is opened, access net service centre's chain of command updates passback informational table of nodes, as shown in table 7:
The access net service centre's chain of command of table 7 is directed to the updated passback informational table of nodes of Fig. 9
In table 7, the state of AP2 is updated to open by closing.
Step 102: when returning, the passback nodal information in informational table of nodes changes and/or the business in wireless small station needs
It asks when changing (such as initiating business request, business demand become larger), access net service centre's chain of command is returned according to update
The service request in informational table of nodes and/or wireless small station is passed, selects more suitable return path for wireless small station, so that passback road
Diameter is optimized, such as the hop count of return path reduces (level of source node reduces), passback handling capacity increases etc..
The step 102 is mainly realized by return network Topology Management and optimization function.
For example, AP2 is opened, while when the handling capacity of AP5 increases to 600Mbps from 200Mbps, the level of AP2 is 0, layer
Grade is smaller, while the passback handling capacity of AP4 is 500Mbps, is not able to satisfy the business demand of AP5.Therefore, access net service centre
Chain of command is that AP5 selects new return path<AP2-AP5>.Wherein, the hop count of AP5 return path is reduced to the 1 jump (layer of AP5
1) grade is reduced to, passback handling capacity increases to 600Mbps.
Step 103: the service centre's management of access net configures message towards wireless small station and passback node transmitting path, wherein
Routing information after optimizing return path comprising wireless small station.
Step 104: the return path that access net service centre's chain of command is optimized based on wireless small station, according to the passback of update
The service request in informational table of nodes and/or wireless small station is divided again for the return link on the return path of wireless small station optimization
Radio resource is redistributed with radio resource, and for the access link in wireless small station, the radio resource of distribution includes work frequency
Point, bandwidth etc..
The step 104 is mainly realized by passback resource management and optimization function.
For example, the return path<AP2-AP5>based on AP5 optimization, the frequency point that AP2 is supported is { f1, f3 }, what AP5 was supported
Frequency point is { f2, f3 }, and the intersection of the two is f3.Therefore, access net service centre's chain of command is the frequency on AP5 selection return link
Point is f3, is that AP5 selects the frequency point on access link for f2.
Step 105: the service centre's management of access net sends resource distribution message towards wireless small station and passback node, wherein
After optimizing return path comprising wireless small station, the radio resource of each return link and wireless small station access link in return path
Radio resource, radio resource includes working frequency points, bandwidth etc..
Further, access nets service centre's chain of command while for the return path of wireless small station selection optimization,
It is assigned with radio resource.Therefore, path configuration message and resource distribution message can be sent in a signaling, such as wireless small
It stands configuration message, wherein the routing information of the return path comprising the optimization of wireless small station and the return link redistributed and connecing
The radio resource of incoming link.
For example, the configuration message of AP5 be<AP2 (f1)-(f3,600Mbps)-AP5 (f2)>.
After the passback handling capacity change of AP5, the passback informational table of nodes such as table 8 of access net service centre's chain of command update
It is shown:
The updated passback informational table of nodes of table 8 (is mainly caused by the passback handling capacity change of AP5)
According to above-mentioned change, the return path that access net service centre's chain of command updates is as shown in table 9:
The updated return path of table 9 (is mainly caused by the passback handling capacity change of AP5)
Step 106: after wireless small station receives path configuration message and resource distribution message, needing to build with new upstream node
Return link has been found, the preparation of normal work is carried out, while can also have been cancelled and the existing return link of former upstream node.Together
When, after passback node receives path configuration message and resource distribution message, needs to establish return link with downstream node, carry out
The preparation of wireless backhaul service is provided, while can also be cancelled and the existing return link of former downstream node.
For example, AP5 and AP2 establish return link, AP5 opens the frequency point f3 and access link frequency point f2 of return link,
AP5 and AP4 cancels existing return link.AP2 and AP5 establishes return link, and AP2 opens the frequency point f3 of return link and connects
Incoming link frequency point f1, the business datum on return link between AP2 reserves bandwidth, and carries out scheduling of resource.AP4 and AP5
Cancel existing return link.
Because the interactive process of distributed group each node off the net is similar with the interactive process of hybrid networking, no longer carry out herein
Detailed description.
