Problems solved by technology

[0034] The purpose of the present invention is to provide a method for the access service network gateway in a WiMAX network to obtain the information of adjacent base stations, so as to solve the problem of how the access service network gateway (ASN GW) obtains the base station (BS) under its jurisdiction when switching is initiated. Neighboring base station (BS) problem of

specific Embodiment approach

[0057] 1. When the ASN GW on the network side initiates a handover, the specific implementation method for the ASN GW to obtain the neighboring BS information of the BS under its jurisdiction is as follows:

[0058] Make the ASN GW know which BSs it governs, and each BS also knows its neighboring BSs. When the ASN GW on the network side initiates a handover, the ASN GW sends a message to the BS under its jurisdiction to obtain information about neighboring BSs. as shown in picture 2:

[0059] Two new messages are added between the ASN GW and the BS: Neighbor BS Request and Neighbor BS Response. The cells carried by the message are listed in Table 1.

Abstract

A method of switching in service network gateway in WiMAX network for obtaining information of adjacent base station includes sending request message of adjacent base station to its controlled base station by switching in service network gateway when service network gateway is switched in network side for launching switching over, sending response message of adjacent base station to switching in service network gateway by said base station to let switching in service network gateway obtain information of base station adjacent to said base station.

Description

technical field [0001] The invention relates to WiMAX network communication technology, in particular to a method for accessing a service network gateway in a WiMAX network to obtain adjacent base station information. Background technique [0002] The full name of WiMAX is Worldwide Interoperability for Microwave Access. The Chinese name is Microwave Access Global Interoperability. This is a set of standardized wireless communication technologies that provide long-distance high-traffic broadband transmission services. Unlike wireless local area networks whose transmission distance is only 100 meters, WiMAX's transmission distance can reach 50 kilometers. As long as a base station is set up, the entire region can achieve high-speed Internet access anytime and anywhere, which is unmatched by wireless local area networks. In addition, WiMAX can also bring unpredictable business opportunities for VoIP network telephones. Although the current network computers are cheap, they mus...
