In addition, in specific implementation process, wireless side Management Controller is in the interconnection for receiving the transmission of third network side node When signaling, the interconnection instruction information of the first network side gusset having determined and the second network side node is can be combined with, is the The communication requirement of three network side nodes generates most rational interconnection instruction information.

It specifically, can be to wireless when third network side node, which needs to establish with the second network side node, to be communicated to connect Side Management Controller sends the second interconnection signaling.Wireless side Management Controller, can be with base after receiving the second interconnection signaling The information of communication connection has been established between the second interconnection signaling and the second network side node and first network side gusset, The second interconnection instruction information is sent to transmission-side upper layer controller, which, which is used to indicate, establishes third network Data transfer path between side gusset and first network side gusset, further, transmission-side upper layer controller can be based on connecing The the second interconnection instruction information received, determines the data transfer path between third network side node and first network side gusset.This Sample, it is only necessary to data transfer path, third network side node are established between third network side node and first network side gusset It can be multiplexed the data transfer path being had built up between the second network side node and first network side gusset, can not only be filled Divide the bandwidth resources using transmission equipment side network, and transmission-side upper layer controller can be reduced and repeat to determine the behaviour of transmission path Make.

It, can be with preferably, when wireless side Management Controller receives multiple interconnection signalings that each network side node is sent The interconnection of each network side node is needed to carry out statistics and analysis, and then combs out between each network side node that more preferably interconnection needs Want information.

In specific implementation process, if wireless side Management Controller have received multiple network side nodes send respectively it is mutual Even signaling, is also based on the interconnection signaling, preset interconnection request rule of response, this multiple network side section of reception Point established connection information, and ask the target network side gusset connecting to build respectively with this multiple network side node Vertical link information determines the interconnection information of this multiple network side node, here, is wrapped in the interconnection information of each network side node Containing the other network side node information being connect with the network side node.Wherein, preset interconnection request rule of response has very It is more, such as the data transfer etc. of maximum number of connections or base station that base station can be established simultaneously, it will not enumerate herein, this Outside, preset interconnection request rule of response can also be adjusted according to the actual interconnection situation of multiple network side nodes； Multiple network side node established connection information and the target network connecting is asked respectively with this multiple network side node Side gusset established connection information all refers to this multiple currently valid link information of network side node, does not include wireless Side Management Controller has indicated the link information for the network side node removed.

Further, wireless side Management Controller is again based on determining above-mentioned interconnection information, to transmission-side upper layer controller Interconnection instruction information is sent, so that transmission-side upper layer controller is that this multiple network side node determines data transfer path.

In the following, by taking multiple network side nodes are all base station as an example, the above process is illustrated.

Assuming that the interconnection signaling that wireless side Management Controller receives base station 3, base station 4, base station 5 are sent respectively, determines base 3, base station 5 of standing is required for establishing with base station 1 and connects, and base station 4, which needs to establish with base station 1, base station 2 respectively, to be connected, also, base station 1 Effective connection is established with base station 2.So, wireless side Management Controller can analyze these connection requirements, for example, Base station 4, which needs to establish with base station 1, base station 2 respectively, to be connected, and effective connection has been established in base station 1 with base station 2, it is possible to allow Base station 4 is directly established with base station 1 and is connected, and is connected in this way, base station 1 needs to establish with base station 4 and base station 2 simultaneously.Assuming that base station 1 is same When the maximum number of connections that can establish be 3, then, base station 1 for the connection requirement of base station 3 and base station 5 can only meet wherein it One, at this point it is possible to analyze the data transfer of base station 3 and base station 5, however, it is determined that the data transfer of base station 3 is larger, then It establishes and connects for base station 3 and base station 1, the connection requirement of refusal or delay response base station 5；If it is determined that the data transfer of base station 5 It is larger, then it establishes and connects for base station 5 and base station 1, the connection requirement of refusal or delay response base station 3.

In specific implementation process, in order to make the data transmission between first network side gusset and the second network side node more Add flexibly, also for the bandwidth resources for preferably utilizing transmission equipment side network.Wireless side Management Controller is determining first network side When sign off between node and the second network side node, instruction can also be sent to transmission-side upper layer controller and remove data The dismounting of transmission path instructs, and correspondingly, transmission-side upper layer controller can be instructed based on the dismounting of reception, removes first network Data transfer path between side gusset and the second network side node, in this way, first network side gusset and the second network side node Between data transfer path foundation and remove it is all more flexible, quick, can not increase transmission network element under the premise of, improve The data transfer of transmission equipment side network.
