For example, AP5 is the AP of plug and play, after it starts shooting access network, the management of access network service centre Face is according to passback informational table of nodes and its business demand (such as handling capacity 200Mbps, time delay<50ms Deng) for it return path is set up automatically<AP1 (1Gbps,<1ms)-AP4 (500Mbps,<5ms) - AP5 (200Mbps,<50ms)>.Need when nodal information changes (such as AP2 unlatchings) and/or business Ask when changing (such as handling capacity increases to 600Mbps), access network service centre chain of command is that it is selected Select new return path<AP2 (1Gbps,<1ms)-AP5 (600Mbps,<50ms)>, wherein returning The jumping figure for passing path is reduced (level of source node reduces), and passback handling capacity increase, return path is optimized.

3rd, the management of return network resource and optimization function

Based on the current wireless backhaul network topology for determining and return path, radio resource allocation is carried out (for example Working frequency points, distribution of bandwidth etc.), make Internet resources adapt to the change of data transfer, effectively lift wireless returning Pass the efficiency and transmission performance of Internet resources.

Based on the current wireless backhaul network topology for determining and return path, by wireless backhaul resource allocation and Link scheduling, realizes the transmission of small station return data.Return network resource management and optimization function are with radio chains Road is carried out for unit.Relaying small station in return network may simultaneously service multiple downstream small stations, it is also possible to Multiple small stations have identical upstream small station.According to each small station itself return data queue and relay data team Row, dispatch corresponding small station and link and send return data in corresponding time slot, so as to meet business service matter Amount is required.By return network resource management and optimization function, (for example, several points on less time granularity Clock, several seconds) make Internet resources adapt to the change of data transfer, effectively lift the effect of wireless backhaul Internet resources Rate and transmission performance.

For example, the frequency that AP5 is supported is f2, f3, the return path set up of starting shooting for it, access network clothes Frequency f2, f4 that business centre management face is supported according to passback informational table of nodes middle and upper reaches small station AP4, are that it divides Working frequency points f3 of working frequency points f2 with return link and access link.After return path is changed, access Net service centre chain of command is that it and the return link between the AP2 of upstream small station share out the work frequency f3, is it Access link shares out the work frequency f2.

The self-configuring process of return network is in distributed networking：

In distributed networking, without centralized node, access network service centre chain of command carries out oneself of return network Configuration, as shown in fig. 6, the solid line link in Fig. 6 is existing return link, dotted line link is newly-built passback Link, the link between terminal and small station is access link.Wherein, macro station deploys wired passback, small station For wireless backhaul, from deployment or plug and play, small station can set up return path with small station around, macro station.

As shown in fig. 7, distributed group is off the net, the interaction of each node is mainly in network：

Step 71：Access network service centre chain of command is managed to returning node, safeguards passback nodal information Table.The information of passback node includes positional information, ability information, status information, back information etc..

The step 71 is main by passback node administration functional realiey.

The information of passback node can be obtained by the network design initial stage, i.e. the network design initial stage takes in access network Business central record returns the information of node；Acquisition can also be reported by nodal information, that is, returning node will be from Oneself positional information, ability information, status information, back information etc. report access network service centre.

For example, for the distributed networking in Fig. 6, the passback node that access network service centre chain of command is safeguarded Particular content in information table as shown in table 2, wherein, in the passback informational table of nodes comprising macro station, AP2, The information of AP3 and AP5.

The passback informational table of nodes that the access network service centre chain of command of table 2 is safeguarded for Fig. 6

Meanwhile, the existing return path of access network service centre chain of command is as shown in table 3：

Already present return path in Fig. 6 of the access network service centre 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 2 Bar return path (single-hop and 2 jumps return path).AP2 has 1 upstream node, 2 downstream nodes；AP3 There is 1 upstream node, without downstream node；AP5 has 2 upstream nodes, without downstream node.

Step 72：After wireless small station (AP1, AP4, AP6, AP7) start, in the frequency (bag supported Include the frequency in macro station and/or small station) on carry out nearby region measurement.

For example, the frequency that AP1 is supported includes 2.0GHz, 3.4GHz-3.6GHz.Meanwhile, the macro station of surrounding 2.0GHz is operated in, the AP of surrounding is operated in 3.5GHz.So, AP1 carries out nearby region measurement, obtains week Reference Signal Received Power (RSRP) measurement result of macro station and AP is enclosed, the RSRP of macro station is -80dBm, The RSRP of AP2 is -90dBm, and the RSRP of AP3 is -110dBm.

Step 73：Wireless small station sends access network request to access network service centre chain of command, comprising it Ability information, business demand, nearby region measurement result etc..

For example, AP1 selects the maximum node macro stations of RSRP, after carrying out Stochastic accessing, by RRC information Access network request is sent, is { f1, f2 } comprising the frequency supported, handling capacity is 200Mbps in passback demand, Disturbed condition (such as RSRP sums) f1 on each frequency of nearby region measurement result>F2, macro station connecing the AP1 Enter network request and be transmitted to access network service centre.

Step 74：Access network service centre chain of command is according to the access network request in wireless small station and maintenance Passback informational table of nodes, is newly to access wireless small station to select suitable return path, and source is included in return path The intermediate node of node, destination node and institute Jing.

It should be noted that the step 74 is mainly by return network Topology Management and optimization functional realiey.

For example, the level of macro station is 0, and the frequency of support is { f1 }, and the handling capacity of existing return link is 1Gbps, Time delay is less than 1ms.Access network service centre chain of command carries out return link judgement, because of 1000>200+delta (delta=10Mbps) the passback demand of AP1 can, be met, its frequency that can set up return link for AP1 Point is f1, therefore, access network service centre chain of command is that AP1 selects return path<Macro station-AP1>.

It should be noted that delta is the handling capacity surplus for arranging, for preventing certain traffic fluctuations from affecting.

Step 75：The management of access network service centre configures message towards wireless small station and passback node transmitting path, Wherein include after wireless small station access network, the routing information of the return path of foundation.

Additionally, return path is updated to state as shown in table 4 by access network service centre chain of command：

When newly adding wireless small station in the Fig. 6 of table 4, the return path after renewal

Step 76：Access network service centre chain of command is based on the newly-established return path in wireless small station, according to nothing The access network request in line small station and the passback informational table of nodes of maintenance, are the passback for newly accessing wireless small station Return link distributing radio resource on path, and for the access link distributing radio resource in wireless small station, The Radio Resource of distribution includes working frequency points, bandwidth etc..

It should be noted that the step 76 is mainly by return network resource management and optimization functional realiey.

For example, based on the return path that AP1 is newly-built<Macro station-AP1>, the frequency that macro station is supported is { f1 }, The frequency that AP1 is supported is { f1, f2 }, and both common factors are f1.Although nearby region measurement result is on each frequency Disturbed condition (such as RSRP sums) f1>F2, but the frequency of return link is only between macro station and AP1 f1.Therefore, it is f1 that access network service centre chain of command selects the frequency on return link for AP1.Due to AP1 Frequency f2 is also supported, while the interference on f2 is less, so access network service centre chain of command is AP1 selections Frequency on access link is f2.

Step 77：The management of access network service centre sends resource distribution message towards wireless small station and passback node, Wherein comprising after wireless small station access network, the Radio Resource of each return link and wireless little in return path Stand the Radio Resource of access link, Radio Resource includes working frequency points, bandwidth etc..

Further, access network service centre chain of command is selecting the same of newly-built return path for wireless small station When, also it is assigned with Radio Resource.Therefore, path configuration message and resource distribution message can be in a signalings In send, for example wireless small station configures message, wherein the letter of the path comprising the newly-built return path in wireless small station The Radio Resource of breath and the return link for distributing and access link.

For example, the configuration message of AP1 is<Macro station (f1)-(f1,200Mbps)-AP1 (f2)>.

Step 78：Wireless small station is received after path configuration message and resource distribution message, is needed and upstream node Return link is established, the preparation of normal work is carried out.Meanwhile, passback node receive path configuration message and After resource distribution message, need and downstream node establishes return link, carry out and wireless backhaul service is provided Prepare.

For example, AP1 and macro station establish return link, and AP1 opens the frequency f1 of return link and accesses chain Road frequency f2, macro station is the reserved bandwidth of business datum on the return link between AP1, and carries out resource tune Degree.

Because the interaction of hybridized group each node off the net is similar with the interaction of distributed networking, here is not It is described in detail again.

Example IV

As shown in figure 8, the management method of the return network of the present embodiment, including：

Step 81, obtains access network request during wireless small station addition network；

Step 82, obtains passback informational table of nodes；

Step 83, is the wireless small station point according to the access network request and passback informational table of nodes With the first passback configuration information；

Step 84, sends the first passback configuration information to the wireless small station so that the wireless small station Corresponding return link is set up according to the described first passback configuration information；

Step 85, when the triggering message of the first passback configuration information change in the wireless small station is got, Described first passback configuration information is changed to into the second passback configuration information；

It should be noted that the triggering message includes that the information of the passback node in passback informational table of nodes occurs The business demand in change and/or the wireless small station changes.

Step 86, sends the second passback configuration information to the wireless small station so that the wireless small station Corresponding return link is set up according to the described second passback configuration information.

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.

Above-described embodiment is directed to, the self-optimizing process of the return network off the net to hybridized group is specifically retouched State as follows.

In hybrid networking, by access network service center controls, (centralized node function is put into and connects for a part of base station Networking service centre), another part base station carries out passback net without centralized node, access network service centre chain of command The self-optimizing of network, as shown in figure 9, the solid line link in Fig. 9 is existing return link, dotted line link is excellent Change return link, the link between terminal and small station is access link.Wherein, AP1 and AP2 are by access network Service center controls, they are wired passback and access network service centre between, can carry out data and signaling Transmission.Wire link (such as X2 mouths) is set up between macro station and access network service centre, data can be carried out With the interaction of signaling.AP3, AP4 and AP5 are the AP of plug and play, and for distributed group net mode, AP3 Wireless backhaul is established and macro station between, macro station provides passback service for it.Establish between AP4 and AP1 Wireless backhaul, AP1 provides passback service for it.After AP5 starts, access network service centre chain of command is it Set up return path and distribution passback resource.

As shown in Figure 10, hybridized group is off the net, and the interaction flow of each node is during network passback self-optimizing：

Step 101：Access network service centre chain of command is managed to returning node, safeguards passback nodal information Table.When nodal information changes, access network service centre chain of command updates passback informational table of nodes.Section Point information change including passback node positional information change (for example node motion or coordinate generation Change), status information changes (for example open and become to close or close to become to open), and back information is sent out Changing (for example returning handling capacity, level increases or reduce) etc..

For example, for Fig. 9 in hybrid networking, the passback node that access network service centre chain of command is safeguarded Particular content in information table as shown in table 5, wherein, in the passback informational table of nodes comprising macro station, AP1, The information of AP2, AP3, AP4 and AP5.

The access network service centre chain of command of table 5 is directed to the passback informational table of nodes of Fig. 9 records

Meanwhile, the existing return path of access network service centre chain of command is as shown in table 6：

The access network service centre chain of command of table 6 is directed to the already present return path of Fig. 9 records

After AP2 is opened, access network service centre chain of command updates passback informational table of nodes, as shown in table 7：

The access network service centre chain of command of table 7 is directed to the passback informational table of nodes after Fig. 9 updates

In table 7, the state of AP2 is updated to by closing to open.

Step 102：When passback nodal information in passback informational table of nodes changes and/or wireless small station Business demand change (such as initiating business request, business demand become big) when, access network service centre Chain of command, according to the passback informational table of nodes for updating and/or the service request in wireless small station, is that wireless small station selects More suitably return path so that return path is optimized, the jumping figure of such as return path is reduced and (saved in source Point level reduce), passback handling capacity increase etc..

The step 102 is mainly by return network Topology Management and optimization functional realiey.

For example, AP2 open, while the handling capacity of AP5 from 200Mbps increase to 600Mbps when, AP2 Level be 0, level is less, at the same the passback handling capacity of AP4 be 500Mbps, it is impossible to meet AP5's Business demand.Therefore, access network service centre chain of command is that AP5 selects new return path<AP2—AP5>. Wherein, the jumping figure of AP5 return paths is reduced to 1 jump (level of AP5 is reduced to 1), and passback handling capacity increases Greatly to 600Mbps.

Step 103：The management of access network service centre configures message towards wireless small station and passback node transmitting path, Wherein optimize the routing information after return path comprising wireless small station.

Step 104：Return path of the access network service centre chain of command based on the optimization of wireless small station, according to renewal Passback informational table of nodes and/or wireless small station service request, be on the return path of wireless small station optimization Return link redistributes Radio Resource, and redistributes Radio Resource for the access link in wireless small station, The Radio Resource of distribution includes working frequency points, bandwidth etc..

The step 104 is mainly by passback resource management and optimization functional realiey.

For example, the return path for being optimized based on AP5<AP2—AP5>, the frequency that AP2 is supported is { f1, f3 }, The frequency that AP5 is supported is { f2, f3 }, and both common factors are f3.Therefore, access network service centre chain of command is It is f3 that AP5 selects the frequency on return link, is that the frequency on AP5 selection access link is f2.

Step 105：The management of access network service centre sends resource distribution message towards wireless small station and passback node, After wherein comprising wireless small station optimization return path, the Radio Resource and nothing of each return link in return path The Radio Resource of line small station access link, Radio Resource includes working frequency points, bandwidth etc..

Further, access network service centre chain of command is in the same of the return path that optimization is selected for wireless small station When, also it is assigned with Radio Resource.Therefore, path configuration message and resource distribution message can be in a signalings In send, for example wireless small station configures message, wherein the path letter of the return path comprising the optimization of wireless small station The Radio Resource of breath and the return link redistributed and access link.

For example, the configuration message of AP5 is<AP2 (f1)-(f3,600Mbps)-AP5 (f2)>.

After the passback handling capacity change of AP5, the passback nodal information that access network service centre chain of command updates Table is as shown in table 8：

Passback informational table of nodes (mainly being caused by the passback handling capacity change of AP5) after the renewal of table 8

According to above-mentioned change, the return path that access network service centre chain of command updates is as shown in table 9：

Return path (mainly being caused by the passback handling capacity change of AP5) after the renewal of table 9

Step 106：Wireless small station is received after path configuration message and resource distribution message, is needed and new upstream Node establishes return link, carries out the preparation of normal work, while can also cancel with former upstream node Some return links.Meanwhile, passback node receive path configuration message and resource distribution message after, need and Downstream node establishes return link, carry out provide wireless backhaul service preparation, while can also cancel and The existing return link of former downstream node.

For example, AP5 and AP2 establish return link, and AP5 opens the frequency f3 of return link and accesses chain Road frequency f2, AP5 and AP4 cancel existing return link.AP2 and AP5 establish return link, AP2 opens the frequency f3 and access link frequency f1 of return link, is the industry on the return link between AP2 The reserved bandwidth of business data, and carry out scheduling of resource.AP4 and AP5 cancels existing return link.

Because the interaction of distributed group each node off the net is similar with the interaction of hybrid networking, here is not It is described in detail again.

The above embodiment of the present invention solves how the small station in super-intensive networking for wireless backhaul carries out autogamy Put the problem with self-optimizing.When wired passback is not disposed in small station, access network service centre chain of command passes through Flexible configuration wireless backhaul links allow small station to dispatch wireless backhaul links to carry out data transmission, the present invention The self-configuring and self-optimizing of return network are realized, is that the plug and play for realizing small station provides the foundation.Relatively In prior art, UDN networks and more efficiency and practicality are more applicable for.
