Embodiment Construction

[0030] In the embodiment of the present invention, when the SCTP link establishment conflict is determined in the process of establishing the X2 connection, the comparison identification of itself is compared with the comparison identification of the opposite end; according to the comparison result, when the client is determined to be the client, an X2 establishment request is sent to the opposite end message; according to the comparison result, when it is determined that it is the server, it receives the X2 establishment request message from the opposite end. Since the embodiment of the present invention can negotiate the X2 connection when the working modes of the two eNBs conflict, it is avoided that the two eNBs send X2 establishment request messages to the opposite end at the same time.

[0031] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] Such as figure 2 As shown, the X2 conn...

Abstract

The embodiment of the invention relates to wireless communication technologies, in particular to an X2 connection negotiation method, an X2 connection negotiation system and a base station, which are used for solving the problem in the prior art that two home nodes B (eNB) simultaneously transmit X2 establishment request messages to opposite terminals. The method of the embodiment of the invention comprises the following steps of: when one eNB determines a simple control transmission protocol (SCTP) link establishment conflict in an X2 connection establishment process, comparing own comparison identifier with the comparison identifier of the opposite terminal; when the eNB is determined to be a client, transmitting the X2 establishment request message to the opposite terminal according tothe comparison result; and when the eNB is determined to be a server, receiving the X2 establishment request message from the opposite terminal according to the comparison result. The method of the embodiment of the invention can avoid the two eNBs simultaneously transmitting the X2 establishment request message to the opposite terminals to further avoid a conflict between operating modes of the two eNBs causing the condition of X2 connection establishment failure and further increase the success rate of X2 connection establishment.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a X2 connection negotiation method, system and base station. Background technique [0002] In SON (Self-Organized Network, self-organizing network), the X2 interface is located at the access network layer. X2 is the logical interface between eNB (base station) and eNB. Each eNB can have X2 connections with multiple adjacent eNBs. . [0003] The X2 establishment process is as follows: figure 1 Shown: [0004] Steps 1-3: eNB1 discovers a new neighbor cell through UE (user terminal) measurement, reports to O&M (Operations&Maintenance, operation and maintenance) equipment, and the O&M equipment sets the "No X2" attribute; [0005] Steps 4-7: eNB1 obtains the transport layer address of the target eNB2 through the configuration transmission process of the S1 interface; [0006] Step 8: eNB1 and eNB2 check whether the physical connection exists, and establish an underlying SCTP (...
