B2 (C2, C3, C4, C5), B3's (C3, C4, C5) and concentration node constitute the of starting radio node A1
Two jump radio node collection；That is, the second of starting radio node A1 jumps radio node collection
H2={ C1, C2, C3, C4, C5 }；
Obtain starting radio node A1 the 3rd jumps radio node collection：Obtain radio node C1, C2,
C3, C4, C5 single-hop path set：C1(D1,D2)、C2(D1,D2,D3)、C3(D3,D4,D5)、C4(D3,
D5)、C5(D3,D4,D5)；C1(D1,D2)、C2(D1,D2,D3)、C3(D3,D4,D5)、C4(D3,D5)、
What C5's (D3, D4, D5) and concentration node constituted starting radio node A1 the 3rd jumps radio node
Collection；That is, the 3rd of starting radio node A1 the jumps radio node collection H3={ D1, D2, D3, D4, D5 }；
In the potential backhaul node hierarchy of the radio node A1 shown in Fig. 2, to A1 or extremely
The group node of hop count identical one of different cable ports (D1, D5) is latent by means of this as a layer
In backhaul node hierarchy figure, it may be determined that starting radio node A1 to the first mesh radio node
(D1) radio node A1, is originated to the different wireless backhaul roads of the radio node (D5) of the second mesh
Footpath.
Preferably, return radio path administrative unit obtains the backhaul biography of each radio node shown in Fig. 2
Movement Capabilities and currently available backhaul transport resource, for determining specific operating path, work for A1
The quantity in path matches somebody with somebody return path again for A1.
Shown in Figure 3, the up and/or downstream transmission bandwidth according to required for A1 uses Fig. 3 institutes
The potential backhaul pathways hierarchical diagram and the following factor of combination shown determine to originate radio node A1 to first
Purpose radio node D2, the radio node D3 of the second mesh, the radio node D5 of the 3rd mesh transmission road
Footpath；The radio node D2 of first mesh described here, the radio node D3 of the second mesh, the nothing of the 3rd mesh
Line node D5 is switching node of the wireless backhaul channel to wire-line back haul channel；
Determine currently available backhaul pathways number and every backhaul pathways it is available up and/or descending
Bandwidth；
Judge whether an available backhaul path have up required for radio node A1 and/or
Downstream transmission bandwidth；
If so, then using this backhaul pathways as radio node A1 return pass；
Otherwise, two or a plurality of backhaul pathways are selected as radio node A1 return pass.
In this citing, it is assumed that the transmission bandwidth required for radio node A1 is uplink/downlink
500MHz/1000MHz, currently available path and its available bandwidth (are cable port and radio node
The bandwidth that can be provided under integration capability) be respectively：
First backhaul pathways:A1B1C2D2, available bandwidth uplink/downlink 200MHz/200MHz；
Second backhaul pathways:A1B2C3D3, available bandwidth uplink/downlink 200MHz/400MHz；
3rd backhaul pathways:A1B3C5D5 (or, A1B3C4D5), available bandwidth uplink/downlink 200MHz
/400MHz；
4th backhaul pathways:A1B1C1D1, available bandwidth uplink/downlink 100MHz/100MHz；
The transmittability of four backhaul pathways of summary, uses this three articles of roads of the first to the 3rd backhaul pathways
Footpath can provide up as wireless backhaul link, three return pass in the way of parallel transmission
600MHz transmission bandwidths and descending 1000MHz transmission bandwidths, meet A1 bandwidth demand.
Specifically, in three links shown in completion Fig. 3 with postponing, due to radio node C3 failures,
Need to match somebody with somebody the second backhaul pathways again for A1:A1B2C3D3 (its available bandwidth uplink/downlink 200MHz/400
MHz), it is shown in Figure 4, in this case, in addition to as follows again match somebody with somebody return path the step of：
There is potentially useful node C4 in the single-hop path set B2 (C2, C3, C4, C5) for judging B2, and
The radio node D3 of the second mesh is included in C4 single-hop path set C4 (D3, D5), therefore, by subpath
B2C4D3 as sub- B2C3D3 candidate's backhaul subpath；
Judge the transmission bandwidth that path A1B2C4D3 can be provided, be as a result available bandwidth uplink/downlink 250
MHz/400MHz, the transmission bandwidth be more than before path A1B2C3D3 transmission bandwidth, therefore,
It is path A1B2C4D3 that second backhaul pathways are matched somebody with somebody again, referring to Fig. 4 solid line B2C4, shown in C4D3.
