X2 interface building method, management method and management device

Abstract

The embodiment of the invention discloses a method for managing an X2 interface between a small base station and a macro base station through a small base station gateway. The method comprises the step of triggering an X2 interface management process after the small base station gateway receives address enquiry information which is transmitted by a first base station and is used for enquiring the address of a second base station. By introducing a judgment mechanism in an HeNB gateway (HeNBGW) and by using information of the HeNBGW about an HeNB / Macro eNB, the X2 interface of HeNB-HeNBGW-Macro eNB is built, the building process of the X2 interface of HeNB-HeNBGW-Macro eNB is optimized and the signaling overhead is reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for establishing and managing an X2 interface, and a device. Background technique [0002] A small base station, such as a pico base station (Pico eNB), a home base station (Home eNB, HeNB), and a Femto base station, may be set up under the coverage area of ​​a macro base station (Macro eNB) in a wireless network. These small base stations are connected to the core network through wires. Because the capacity of wired access (such as optical fiber) is large, this connection networking method enhances network coverage and makes the entire communication system have a higher capacity. [0003] Taking the Long Term Evolution (LTE) heterogeneous network as an example, for example, figure 1 As shown, the HeNB covered by the Macro eNB is connected to the core network through a small base station gateway (such as a home base station gateway HeNB GW). In scenarios such as ...

Problems solved by technology

[0007] The above method does not consider the establishment of the X2 interface of the HeNBGW-HeNB when the X2 interface of the Macro eNB-HeNBGW is established, so the established X2 interface of the HeNBGW-Macro eNB cannot obtain some information corresponding to the X2 setup message of the HeNB, such as the service of the HeNB Community, neighbor community information, etc.

Therefore, some information corresponding to the X2 setup message needs to be exchanged between the HeNB and the Macro eNB by using other dedicated messages after the two X2 interfaces of HeNB-HeNBGW and HeNBGW-Macro eNB are established, and the subsequent process of information exchange increases. signaling overhead
