A method and device for establishing an x2 link

Abstract

The invention discloses an X2 link establishing method and equipment. The X2 link establishing method comprises the steps that a serving base station sends a first message to a target base station and the first message carries the largest sent stream number of the serving base station and the largest received stream number of the serving base station; the serving base station receives a second message from the target base station, and the second message carries the largest sent stream number of the target base station and the largest received stream number of the target base station; the serving base station determines the received stream number of an X2 link by the utilization of the largest sent stream number carried in the second message and the largest received stream number of the serving base station, and determines the sent stream number of the X2 link by the utilization of the largest received stream number carried in the second message and the largest sent stream number of the serving base station. By means of the X2 link establishing method and equipment, configuring workload for configuring the X2 link in a static mode can be reduced, and the situations like configuring mistakes occurring when the X2 link is configured in the static mode are avoided. In addition, the situation that establishing of the X2 link fails due to the fact that parameters are not uniform can be avoided, and the X2 link is guaranteed to be established successfully.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and equipment for establishing an X2 link. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) network, there is a need for intercommunication between base station devices. Therefore, a link needs to be established between two base station devices. This link is the X2 link, and the X2 link It is used for signaling and service message exchange during cell handover, and the transmission protocol of the signaling plane on the X2 link is SCTP (Stream Control Transmission Protocol, Stream Control Transmission Protocol). [0003] Such as figure 1 As shown, it is a schematic diagram of establishing an X2 link between two base station devices, in figure 1 Wherein, the base station device is an eNB (Evolved Node B, evolved Node B, ie, base station device). [0004] In the prior art, the establishment method of the X2 link can be to...

AI Technical Summary

Problems solved by technology

[0008] Since the number and usage of public and private streams are fixed in the code, there will be a parameter mismatch during the establishment of X2 links of different vendors, which will cause the establishment of X2 links to fail

For example, one manufacturer has 1 dedicated flow, and another manufacturer has 9 dedicated flows. At this time, the number of dedicated flows of the two manufacturers is inconsistent, which will cause the X2 link to fail to be established.
