Refering to shown in Fig. 2, in the embodiment of the present invention, the detailed process setting up x2 link is as follows:
Step 200: judge whether the foundation of the current x2 link and opposite end between of local terminal clashes, if so, execute step
Rapid 210；Otherwise, execution step 220；
Step 210: interrupt the x2 link that local terminal current request is set up, and after the random duration of time delay, send out to opposite end
Send an x2 request for building link message, and return to step 200；
Step 220: complete the foundation of an x2 link.
In the embodiment of the present invention, judge the mode whether foundation of the current x2 link and opposite end between of local terminal clashes
Have multiple, preferably, can be in the following way:
Ip address information according to opposite end sends an x2 request for building link message, wherein, an x2 link to opposite end
Set up the ip address information that request message at least includes local terminal；
Receive the 2nd x2 request for building link message, and judge whether include opposite end in the 2nd x2 request for building link message
Ip address information, and by the first x2 request for building link message triggering an x2 link establishment whether do not complete.
In the embodiment of the present invention, an x2 request for building link message is sent based on sctp, or receive the 2nd x2 link
Set up request message and be based on sctp.
For example: the ip address information based on enb2 for the enb1 sends an x2 request for building link message, wherein, the to enb2
One x2 request for building link message at least includes the ip address information of enb1, and then, enb1 receives the 2nd x2 request for building link
Message, and judge in the 2nd x2 request for building link message, whether to include the ip address information of enb2, and pass through an x2 link
Whether the x2 link establishment setting up request message triggering completes.
In the embodiment of the present invention, either for local terminal still for opposite end, trigger local terminal or opposite end sends x2 link
Set up request message condition have multiple, preferably, when local terminal determine with opposite end have neighboring BS relationship when, then local terminal can be sent out to opposite end
Send an x2 request for building link message, in the same manner, when opposite end determines and has neighboring BS relationship with local terminal, then opposite end can send to local terminal
2nd x2 request for building link message.
Further, in order to improve internet security, in the embodiment of the present invention, local terminal is sending an x2 link to opposite end
After setting up request message, opposite end is not the x2 link set up immediately and local terminal between, but first whether local terminal to be judged has
There is the authority (accessing the authority of opposite end) setting up an x2 link, set up, determining that local terminal has, the authority that an x2 connects
In the case of, then the foundation carrying out an x2 link.
In the embodiment of the present invention, opposite end determines whether the local terminal sending an x2 request for building link message has and sets up the
The mode of the authority of one x2 link has multiple, preferably, local terminal includes the ip of itself in an x2 request for building link message
(internet protocol, Internet protocol) address, then, opposite end after receiving an x2 request for building link message,
Parse ip address therein, and determine when there is, in the ip address of itself storage, the ip address parsing, with regard to ip address relatively
The data channel (data that this data channel only allows and the equipment of ip address specified interacts is passed through) of the equipment answered.This
When, the port information of not only opposite end to be included, the ip address of local terminal also to be included in an x2 request for building link message.
For example, enb1 is sending an x2 request for building link message (in an x2 request for building link message to enb2
The not only port information of enb2 to be included, the ip address of enb1 also to be included) after, enb2 is not to set up immediately and enb1 between
First x2 link, but first judge enb1 whether to have and enb2 between to set up the authority of an x2 link, concrete judgment mode
For: determine in enb2 whether include, in the ip address of storage, the ip address that an x2 request for building link message includes, if so,
Then determine that enb1 has the authority setting up an x2 link and enb2 between, then, set up the x2 link and enb1 between.
Above example be by enb1 to enb2 send an x2 request for building link message as a example that is to say, that
, as client, as server, in actual applications it is also possible to enb2 is as client, enb1 is as clothes for enb2 for enb1
Business device, now it is simply that enb1 judge enb2 whether have foundation and enb1 between the 2nd x2 link authority, detailed process and
Said process is similar to, and here is no longer described in detail one by one.
In the embodiment of the present invention, interrupt the x2 link that local terminal current request is set up mode have multiple, preferably, clearly
Except all configuration resources relevant with an x2 link of local terminal, in actual applications, also other modes, here no longer carries out one
One detailed description.
In actual applications, if delaying and carry out again setting up an x2 link when introducing, local terminal very likely with opposite end it
Between the foundation of x2 link clash again, worst situation is collision loop, cannot complete all the time to set up an x2 chain
Road.Further, in order to avoid link setup conflict to occur again as far as possible, break the conflict that an x2 link establishment is likely to occur and follow
Ring, improves the efficiency being successfully established an x2 link, and that reduces by an x2 link sets up the conflict number occurring, and the present invention is implemented
In example, time delay granularity is set to 100ms, the span of time delay is 1000ms～10000ms.
In the embodiment of the present invention, mode that an x2 link is successfully established has multiple, preferably, first setting up sctp link；
Then, application configuration data is exchanged with opposite end by sctp link, complete the foundation of an x2 link, wherein, setting up sctp
Special data channel to be set up before link, then application configuration data is exchanged with opposite end based on special data channel, complete first
The foundation of x2 link.
Embodiment for a better understanding of the present invention, concrete application scene given below, set up process for x2 link,
Make and describing in further detail, specifically as shown in Figure 3:
When step 300:enb1 determines and enb2 has neighboring BS relationship, the ip address information according to enb2 sends first to enb2
X2 request for building link message, wherein, an x2 request for building link message at least includes the ip address of enb1；
When step 310:enb2 determines and enb1 has neighboring BS relationship, the ip address information according to enb1 sends second to enb1
X2 request for building link message；
The ip address of the enb1 that step 320:enb2 includes according to an x2 request for building link message determines that enb1 has
Have after setting up the authority of an x2 link, set up the data channel for enb1；
After step 330:enb1 receives the 2nd x2 request for building link message, and judge the 2nd x2 request for building link message
Include the ip address information of enb1, and do not completed by an x2 link establishment of an x2 request for building link message triggering
When, determine that the foundation of current x2 link and enb2 between clashes；
Step 340:enb1 interrupts the foundation of a current x2 link；
After step 350:enb2 receives an x2 request for building link message, and judge an x2 request for building link message
Include the ip address information of enb1, and when not completed by the x2 link establishment of the 2nd x2 request for building link message triggering,
Determine that the foundation of current x2 link and enb1 between clashes；
Step 360:enb2 interrupts the foundation of current 2nd x2 link；
After step 370:enb1 time delay 1100ms, send an x2 request for building link message again to enb2, under carrying out
The foundation of x2 link；
Now, because enb2 is still in delay state, also do not carry out the 2nd x2 link establishment next time, therefore,
Enb1 does not find that the foundation of the currently x2 link and enb2 between clashes, and does not just interrupt the foundation of an x2 link.
Step 380:enb1 sets up sctp link；
