Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] figure 1 It is a schematic diagram of roaming of a PHS mobile phone user across calling areas. Such as figure 1 As shown, the calling area A includes base station controllers A1 and A2, the base station controller A1 includes base stations A1-1, A1-2; the area A2 includes base stations A2-1, A2-2. Call area B includes base station controller B1, and B1 includes base stations B1-1 and B1-2. The PHS mobile phone user is originally registered under the base station A1-2 in the calling area A1. When the user moves and registers under the base station B1-1, the mobile phone will obtain the calling area of ​​the base station B1-1 as B through air signaling, and then find that he has roamed from the calling area A to the calling area B, so it will pass The base station sends a message to the network side to initiate a location update proce...

Abstract

The invention discloses a method for improving the reliability of location update in a wireless local telephone system. The core idea is to save the information of the user's previous call area on the HLR, and set a state machine on the HLR to identify each state in the location update process. According to the judgment of the message reported by the BSC, the state transition and corresponding processing are carried out. When the call area information error caused by the incomplete location update process, the HLR will actively initiate the location confirmation process to the user. By adopting the method of the present invention, the reliability of the location update process in the wireless local telephone system is improved, the problem of wrong calling area information caused by message loss is largely avoided, and the call loss when called is reduced. It improves the call rate of the whole system and the satisfaction of users, and at the same time reduces the workload of system maintenance personnel.

Description

technical field [0001] The invention relates to a wireless local telephone system, in particular to a location updating method in the wireless local telephone system. Background technique [0002] The wireless local telephone system is a wireless telephone technology improved on the basis of Japan's PHS (Personal Handset System) and is an extension and supplement of the local telephone network. Because the telephones provided by the existing fixed local telephone network are fixed telephones and do not have mobility, the call volume drops significantly when the user leaves the telephone set. The wireless local telephone system provides a mobile phone that users can carry with them. The mobile phone can initiate and receive calls anywhere within the coverage of the system, which greatly enhances the mobility of users, meets the needs of users for calling anytime and anywhere, and effectively solves the problem of fixed telephones. The problem of "hot installation and cold us...
