Problems solved by technology

[0005] The VRRP backup method, on the one hand, is relatively complicated for the configuration of the gateway; on the other hand, if the gateway device or the BSC interface board in the Layer 2 network does not support VRRP, the above-mentioned only gateway cannot be backed up.

Embodiment Construction

[0027] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] The base station system of the present invention mainly relates to a base station (BTS) and a base station controller (BSC). User configuration, only select a good gateway as the link gateway; in this way, even if a certain gateway fails, the ABIS port (interface between BSC and BTS) can be guaranteed to be normal, and the user data path is unique, so that each device can be guaranteed The normal operation, improve the stability and reliability of the ABIS port. The following description will take a CDMA base station system as an example, but it does not mean that it is limited to a CDMA base station system.

[0029] Before the description, some terms are explained first. In the following, the term "gateway" is used as a general term for gateways; the term "link gateway" is used as a gateway selected to undertake data tr...

Abstract

The invention discloses a method and a device for selecting gateways in a base station system. The gateways are used for forming network links between a base station and a base station controller. The method comprises the following steps: in at least two pre-configured gateways, determining whether a preferred gateway exists; if the preferred gateway exists, determining other gateways as alternative gateways; and when the preferred gateway is valid, selecting the preferred gateway as a link gateway, otherwise, selecting a valid alternative gateway as the link gateway. The device comprises a preferred gateway determining module and a link gateway selecting module, wherein the preferred gateway determining module is used for determining whether the preferred gateway exists in the at least two pre-configured gateways; and the link gateway selecting module is used for determining other gateways as alternative gateways if the preferred gateway exists, selecting the preferred gateway as the link gateway when the preferred gateway is valid and selecting the valid alternative gateway as the link gateway when the preferred gateway is invalid. The method and the device can maintain a communication link accessible in a plurality of gateways and improve system stability and reliability.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a gateway selection method and device in a base station system. Background technique [0002] At present, in mobile communication, there has been a way for base stations to network through Ethernet. In this networking mode, in a base station system, a base station (BTS) communicates with a base station controller (BSC) through Ethernet. [0003] For this IP networking mode in the base station system, there is only one IP address of the external network port exposed by the base station to the BSC. Therefore, generally speaking, only one gateway is configured. Moreover, if it is a two-layer network between BTS and BSC, the interface board IP of BSC must be in the same subnet as the external IP of BTS, and the gateway of BTS is the interface IP of BSC. In this case, generally only one is configured. gateway. [0004] However, for a gateway, once a failure occurs, the entire li...
