Embodiment 1

[0053] This embodiment provides a method for establishing an X2 connection, such as image 3 As shown, it mainly includes the following operations:

[0054] Step 301, when the target base station perceives that it is different from the X2 gateway GW supported by the source base station during the process of obtaining the transport layer address, the target base station negotiates with the source base station to determine the X2GW supported by them;

[0055] In step 302, an X2 connection is established between the target base station and the source base station through a commonly supported X2GW.

[0056]Wherein, when the target base station (for example, eNB or HeNB) perceives that it is different from the X2GW supported by the source base station, it may add or update the X2GW, so that the added or updated X2GW is consistent with that supported by the source base station. For example, when the target base station is an eNB, the target base station adds X2GW so that the added ...

Embodiment 2

[0089] This embodiment provides a base station device, and the device at least includes the following units.

[0090] The first negotiating unit negotiates with the source base station to determine the commonly supported X2GW when sensing that it is different from the X2 gateway GW supported by the source base station during the process of obtaining the transport layer address;

[0091] The link building unit establishes an X2 connection with the source base station through the jointly supported X2GW.

[0092] Wherein, in the process of obtaining the transport layer address, when the above-mentioned base station is an eNB and acts as the target side base station: the first negotiating unit judges whether it is consistent with the X2GW supported by the source base station (such as HeNB), and if they are consistent, directly obtain the address of the transport layer The response message carries the transport layer address of the X2GW; if inconsistent, the first negotiating unit ...

Abstract

The invention discloses a method for establishing an X2 connection and a connection device and relates to the technical field of wireless communications. The method comprises steps that: in a transmission layer address acquiring process, when a target base station perceives that the target base station is different from an X2 gateway GW supported by a source station, the target base station and the source base station negotiate to determine the jointly supported X2GW; and the X2 connection is established between the target base station and the source base station through the jointly supported X2GW. The invention also discloses a base station device. According to the invention, the HeNB and the eNB are allowed to support the same X2GW, so it is ensured that indirect the HeNB / eNB can successfully initiate the indirect X2 establishment.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for initiating indirect X2 establishment between HeNB and eNB, and HeNB and eNB. Background technique [0002] A home base station (HeNB) is a small base station, which mainly assists a macro base station (eNB) in hotspot coverage. It is an integral part of heterogeneous networking, which can effectively improve the coverage of indoor voice and high-speed data services, such as homes, offices, cafes, supermarkets, etc., where femtocells can be installed. The advantages of femtocells are as follows: low cost, low power, small size, and easy deployment. [0003] However, when femtocells and macro base stations are networked together, there is a prominent problem, that is, there may be many links between HeNB and eNB, because thousands of HeNBs may be deployed around one eNB, if eNB and each HeNB There is an X2 link between them, which will bring a ...
