Referring to Fig. 2, the embodiment of the present invention provides a kind of construction method of backhaul pathways, comprising:
Step 101: receiving oneself of each node broadcasts in any at least one other node in relay node periphery
The priority parameters of body；Wherein, the priority parameters of node are smaller, and the corresponding priority of the node is higher；
Based on the network planning, the network optimization or the deployment of actual wireless backhaul network, operation management maintainance can be passed through
(Operation Administration and Maintenance, OAM) is configured to each in wireless backhaul network topology
A relay node distributes a priority parameters, the priority parameters can be characterization relay node to anchor base station node away from
From parameter, be also possible to characterize relay node to anchor base station node minimum number of hops parameter, be also possible to artificially
The fixed value of setting, the embodiment of the present invention are not particularly limited.
Referring to Fig. 3, by taking priority parameters characterize relay node to the distance of anchor base station node as an example: each section in Fig. 3
The number in bracket after point title is the priority parameters of corresponding node.Wherein, apart from anchor base station node Donor gNB compared with
The priority parameters of close wireless relay nodes RN1, RN2, RN3 are 1, apart from the farther away wireless relay nodes of anchor base station node
The priority parameters of RN1, RN2, RN3 are 2, and so on.Wherein, Donor gNB can not have priority parameters, or
The priority parameters of Donor gNB are equal to 0.
Step 102: the priority parameters of any relay node are read from OAM configuration；
In the specific implementation process, any relay node after power-up, can access network first with the identity of UE, carry out
Registration, and download OAM configuration；The relay node can read the priority parameters of itself from OAM configuration, and in small fauna
The priority parameters of the relay node are broadcasted in system information.
Step 103: filtering out cell signal strength from least one other node and meet preset condition and preferential
Grade parameter is less than or equal to other nodes of the priority parameters of any relay node；
Step 104: determining that any relay node is leading to the anchor base station section from other nodes filtered out
Next-hop node on point direction.
In the specific implementation process, the implementation for determining next-hop node from other nodes filtered out includes but not
It is limited to following three kinds:
1st kind: determining a node as next-hop node.
Specific embodiment includes: that other nodes that will be filtered out are arranged according to the sequence of priority parameters from small to large
Sequence determines the node to make number one；Then the node to make number one described in connection is saved as any relaying
Point is in the next-hop node led in the anchor base station node direction.According to such strategy, final any node to anchor point
All there was only an effective path in base station.
In the specific implementation process, when being ranked up to other nodes filtered out, if there is other multiple nodes
Priority parameters it is identical, then other the multiple nodes are ranked up according to the sequence of cell signal strength from big to small.
In the specific implementation process, if led to using the node to make number one as any relay node
Toward after the next-hop node in the anchor base station node direction, detect that any relay node comes first with described
Any relay node then can led to the anchor base station node side by link congestion or failure between the node of position
Upward next-hop node replaces other nodes, for example comes deputy node.
For example, referring to Fig. 3, if the signal strength of Donor gNB meets business demand, RN11 may be selected directly and
Donor gNB establishes connection；If the signal of Donor gNB is not good enough, the RN3 that the preferable priority parameters of RN11 are 1 is carried out
Connection.Similarly, RN12 can preferred RN4 as next-hop node, RN4 can select RN1 as next-hop node, and RN1 selects Donor
GNB will provide service as next-hop node, this paths of such RN12-RN4-RN1-Donor for the UE resided under RN12.
2nd kind: determining multiple nodes, use a node as next-hop node.
Specific embodiment includes: that other nodes that will be filtered out are arranged according to the sequence of priority parameters from small to large
Sequence determines that the N number of node for coming top N, N are the positive integer greater than 1；It connects N number of node, and will make number one
Node as any relay node in the next-hop node led in the anchor base station node direction, by remaining N-1
Point is as spare next-hop node, so that the link between any relay node and the node to make number one
Next-hop node can be quickly switched to spare next-hop node by congestion or failure.
It is similar to mode 1, when being ranked up to other nodes filtered out, if there is the preferential of other multiple nodes
Grade parameter is identical, then is ranked up other the multiple nodes according to the sequence of cell signal strength from big to small.
For example, referring to Fig. 3, RN12 can connect RN5, RN4, RN13 simultaneously, and RN5 can connect RN1, RN4, RN6, RN4 simultaneously
RN1, RN12 can be connected simultaneously, and so on.But RN12 may only select the smallest RN4 of priority parameters in RN5, RN4, RN13
It is serviced for it, RN4 only may select RN1 to service for it, and RN1 only selects Donor gNB to service for it.It finally determines in this way
The path of RN12-RN4-RN1-Donor gNB and mode 1 are consistent.But if in RN12-RN4-RN1-Donor gNB
Occur the problems such as congestion or failure between certain section of link, backup path can be quickly switched into, for example RN4 is monitoring itself to arrive
Next-hop node then can be switched to RN12 by RN1 by the link congestion of RN1.
3rd kind: multiple nodes are determined, all as next-hop node.
Specific embodiment includes: that other nodes that will be filtered out are arranged according to the sequence of priority parameters from small to large
Sequence determines that M before coming M nodes, M are the positive integer greater than 1；Connect the M node, and by the M node
All clothes are provided for UE in the next-hop node led in the anchor base station node direction as any relay node
Business.
It is similar to mode 1, when being ranked up to other nodes filtered out, if there is the preferential of other multiple nodes
Grade parameter is identical, then is ranked up other the multiple nodes according to the sequence of cell signal strength from big to small.
Wherein, specific embodiment of the M node simultaneously to provide service for UE includes:
1) different UE are shunted to different paths, any relay node, will be from difference when transmitting signaling or data
The signaling or data of UE is sent to the different nodes in the M node.
For example, referring to Fig. 3, RN5, can be by the UE's of some new accesses when monitoring that RN5-RN1 link load is higher
Business is put on the link of RN5-RN6 and transmits, or the business of the part UE on RN5-RN1 is transferred to RN5-RN6 chain road
Transmission.
2) the different nodes being sent to different signalings or data from same UE in the M node.
For example, referring to Fig. 3, is considered based on chain-circuit time delay and load etc., the different business of UE2 can be put into RN11 and RN12
It is transmitted on two different nodes.
3) the different nodes being sent to same signaling or Data duplication from same UE in the M node.Especially
It is to consider to carry out repeating transmission to the same business of same UE on multilink, can protect in the case where signal quality is weaker
Demonstrate,prove transmission success rate.
In above scheme, any relay node is when determining that it leads to the next-hop node of anchor base station node, from periphery
Cell signal strength is filtered out in other nodes meet preset condition and priority parameters and be less than or equal to any relaying save
Then other nodes of the priority parameters of point determine that any relay node is leading to institute from other nodes filtered out
State the next-hop node in anchor base station node direction.Wireless relay nodes are when doing Path selection in addition to reference mode
Cell signal strength meets outside preset condition, reference is also made to the priority parameters of node, so that node can be chosen apart from anchor point
The case where base station is closer or the less node of number of hops is as next-hop node, effectively path is avoided to go the long way round, it is ensured that lower
Complexity and expense, improve system effectiveness, can preferably meet the transmission demand of 5G business high-speed low time delay, guarantee
User experience；
Moreover, above scheme additionally provides a variety of routing resources, for example determines a section of highest priority
Point is used as next-hop node, determines that multiple nodes are used as next-hop node etc., can flexibly support various network topology structures
Under Path selection, therefore this programme also has the advantages of flexibility is high, strong applicability.
Based on the same inventive concept, the embodiment of the present invention also provides a kind of construction method of backhaul pathways, is applied to UE, uses
To realize the access point of UE selection wireless backhaul network.Referring to Fig. 4, this method comprises:
Step 201: detecting the cell signal level value of each node in described at least one node of the periphery UE, and receive
The priority parameters of itself of each node broadcasts；
Wherein, the priority parameters of node are smaller, and the corresponding priority of the node is higher；The priority of the node is joined
Number characterize the nodes to anchor base station node distance or the node to anchor base station node minimum number of hops.
Step 202: the node that cell signal level value meets pre-determined threshold is filtered out from least one described node；
Step 203: the smallest node of priority parameters being selected wirelessly to return from the node filtered out as the UE access
The access point of journey network.
For example, referring to Fig. 5, UE1 in the area that collectively covers of Donor gNB and IAB1, Donor gNB that UE1 is measured and
The cell signal level value of IAB1 is all satisfied pre-determined threshold, even when the signal of IAB1 is better than Donor gNB, UE can also be excellent
First select the cell of Donor gNB resident；UE2 is in the covering edge of DonorgNB, the Donor gNB cell signal measured
Level value is well below pre-determined threshold, but being closer from IAB1, therefore the cell signal level value of measured IAB1 can
The cell signal level value of Donor gNB can be significantly larger than, therefore select the cell of IAB1 resident；UE3 is IAB1's and IAB2
The cell signal level value of middle position, the IAB1 measured and IAB2 are all satisfied pre-determined threshold, then UE3 can preferentially select away from
The cell of the IAB1 closer from Donor gNB is resident；The IAB1 cell signal level value that UE4 is measured is well below pre- gating
Limit, but being closer from IAB2, therefore select the cell of IAB2 resident；And UE5, only in the coverage area in IAB2, because
This can only select the cell of IAB2 resident.
In the above scheme, UE is when selecting the access point of wireless backhaul network, other than considering cell signal level value,
It reference is also made to the priority parameters of node, i.e. selection cell signal level value meets pre-determined threshold and the smallest section of priority parameters
Access point of the point as the UE access wireless backhaul network, UE may be selected apart from anchor base station is closer or number of hops more
