System, terminal and method of using xiaolingtong network as third-generation mobile network sub-network

Abstract

This system consists of PHS / 3G twin modes mobile terminal (TMMT), PHS net and 3G mobile net (3MN). When the 3G user uses TMMT and selects prior accessing 3MN mode, 3MN is auto prior accessed. However, in case only PHS wireless signal exists, PHS wireless net is auto accessed. Via the mutual connection between the PHS core net and the 3G core net, the user authentication and the position renewing are realized in the 3G core net while the call is built in the PHS core net. Here, the PHS net is treated as an accessing subnet of 3G net. The structure of this system and terminal are simple. This invention possesses extensive practical application and magnificent meaning. This invention solves the problem of hardly offering comm. service due to the shortage of net covering during the first built stage of 3G net. This invention offers the roaming function for the PHS single mode terminals using 3G number. After obtaining the 3G mobile license, the runner of the solid net can utilize the existed PHS net to offer users a better mobile comm. service.

Description

technical field [0001] The present invention relates to an innovative technology for integrating PHS network with 3G network: a system and method for 3G users to use PHS / 3G dual-mode mobile phone terminals to access 3G network through PHS network to obtain communication services. A system using the PHS network as a subnet of a third-generation mobile network, a PHS / 3G dual-mode mobile phone terminal used in the network system and a method for using the same belong to the field of mobile communication terminal application technology. Background technique [0002] At present (to the end of October 2005), the network capacity of PHS (Personal Handyphone System) in China is close to 100 million lines, and the number of users has exceeded 80 million. At the same time, the implementation of China's 3G mobile license is also a situation that calls for the rain and is ready to come. China Telecom and China Netcom, as fixed network operators, have obtained 3G licenses and become inte...

Problems solved by technology

Another object of the present invention is to provide a kind of use above-mentioned PHS / 3G dual-mode mobile phone terminal, the personal handy phone system PHS, i.e. PHS network as the subnet system and its working method of 3G mobile communication network, thus solve the problem of 3G In the initial stage of network construction, practical problems such as insufficient network coverage and difficulties in providing communication services also create and create opportunities for existing fixed network operators to make full use of their existing PHS networks to provide better mobile communication services for their users after obtaining 3G mobile licenses.
