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.

Embodiment 1

[0038] The current protocol stipulates that the port numbers on the server side and client side of the SCTP coupling of the X2 link are both 36422, so the SCTP coupling can be correctly created. However, the current protocol does not provide for the creation of several flows within the SCTP coupling, but only requires the establishment of one public flow and at least one private flow within the SCTP coupling, which will result in failure to establish the X2 link.

[0039] Aiming at the problems existing in the prior art, Embodiment 1 of the present invention provides a method for establishing an X2 link, which is applicable to the self-establishment process of the X2 link and the static configuration establishment process of the X2 link; for the convenience of description, the present invention implements In this example, the processing of the self-establishment process of the X2 link is taken as an example to describe in detail. The process of establishing the static configura...

Embodiment 2

[0056] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a serving base station, such as image 3 As shown, the serving base station includes:

[0057] The sending module 11 is configured to send a first message to the target base station, where the first message carries the maximum number of transmission flows and the maximum number of reception flows of the serving base station, and the target base station uses the maximum number of transmission flows carried in the first message to transmit The number of streams and the maximum number of streams received by the target base station determine the number of streams received by the X2 link, and the target base station uses the maximum number of streams carried in the first message and the maximum number of streams sent by the target base station to determine X2 The number of send streams for the link;

[0058] A receiving module 12, configured to receive a second mess...

Embodiment 3

[0067] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a target base station, such as Figure 4 As shown, the target base station includes:

[0068] The receiving module 21 is configured to receive a first message from the serving base station, where the first message carries the maximum number of sending flows and the maximum number of receiving flows of the serving base station;

[0069] A determining module 22, configured to determine the number of receiving flows of the X2 link by using the maximum number of sending flows carried in the first message and the maximum number of receiving flows of the target base station, and use the maximum number of receiving flows carried in the first message and the maximum number of transmission streams of the target base station to determine the number of transmission streams of the X2 link;

[0070] The sending module 23 is configured to send a second message to the serving...

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...
