Embodiment Construction

[0079] The link establishment method provided by the embodiment of the present invention, such as figure 1 shown, including:

[0080] S101. The source base station sends a first message to the target base station through the MME.

[0081] Wherein, the first message includes an Internet Protocol (IP, Internet Protocol) address of the source base station and a port number selected by the source base station.

[0082] It should be noted that when the source base station and the target base station automatically establish an X2 link, since the port number of the opposite end cannot be determined, it is required that the local port numbers of the X2 links of all base stations are configured exactly the same. Because the source base station defaults the peer port number to be the same as the local port number, and similarly, the target base station also defaults the peer port number to be the same as the local port number of the target base station, so the port numbers are inconsis...

Abstract

An embodiment of the invention provides a link establishing method, an apparatus and a system, and the invention relates to the communication field, and can increase success probability of X2 link establishment. The method for establishing links comprises the following steps: a source base station sends a first message to an objective base station by mobility management entity (MME), and the first message includes an internet protocol address of the source base station and a terminal number selected by the source base station; the source base station receives a second message sent by the objective base station by MME, and the second message includes an IP address of the objective base station and a terminal number selected by an objective base station; an X2 link is established by the source base station according to the IP address of the source base station, the terminal number of the source base station, and the IP address of the objective base station, the terminal number of the objective base station and the objective base station.

Description

technical field [0001] The present invention relates to communication technology, in particular to a link establishment method, device and system. Background technique [0002] When deploying the network, in the long term evolution system (Long Term Evolution, LTE), the base stations (Evolved Node B, eNB) can communicate with each other by establishing an X2 link, between the eNB and the mobility management entity (Mobility Management Entity, MME) They can communicate with each other through the S1 link, wherein, the X2 link communication between eNBs and the S1 link communication between eNBs and MMEs are all implemented based on Stream Control Transmission Protocol (SCTP). [0003] The X2 link can support user equipment (User Equipment, UE) mobility management functions, etc. If the UE needs to switch from the source base station that has established the X2 link to the target base station, the source eNB judges whether it is connected to the eNB that the target base statio...
