Method, device and system for selecting access gateway

Abstract

The embodiment of the invention discloses a method, device and system for selecting an access gateway, which relate to the technical field of wireless access and solve the problem of influence on communication service quality of a mobile terminal while a micro base station access gateway cannot provide normal service. A technical scheme provided by the invention comprises the steps of selecting a target micro base station access gateway according to service ability information of the micro base station access gateway in a network; and transmitting a message carrying target micro base station access gateway identifier information to the micro base station so that the micro base station is accessed into the target micro base station access gateway corresponding to the target micro base station access gateway identifier information according to the target micro base station access gateway identifier information or the target micro base station access gateway carries out pre-attachment operation on a terminal requesting to enter the network. The method, device and system for selecting the access gateway, which are provided by the embodiment of the invention, can be applied to wireless networks like a network of worldwide interoperability for microwave access (WiMAX).

Description

technical field [0001] The present invention relates to the field of wireless access technology, in particular to a method, device and system for selecting an access gateway. Background technique [0002] In order to improve the network coverage of the Worldwide interoperability for Microwave Access (WiMAX) network, especially indoor coverage, a WiMAX micro-base is deployed indoors, and the WiMAX micro-base is connected to the WiMAX micro-base station network service provider through a broadband network. Core network or WiMAX macro base station network, in which a new WiMAX micro base station network service provider is introduced into the WiMAX network, responsible for the operation, certification and management of WiMAX micro base stations. [0003] In the process of implementing the present invention, the inventors found that the WiMAX micro base station is connected to the micro base station access gateway through the security gateway, and then accesses the core network ...
