Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] see figure 1 , the ellipse in the figure represents the PHS wireless network, and the square represents the 3G wireless network. This figure shows that in the early stage of 3G network construction, its wireless network coverage is definitely not as good as that of the PHS wireless network that has been built for more than three years, and there are quite large "only PHS wireless network signal without 3G wireless signal coverage" area.

[0020] see figure 2 , introducing the PHS / 3G dual-mode mobile phone terminal structure of the present invention. The control circuit includes: a PHS / 3G dual-mode wireless communication function module, a wireless mode selection module, a communication function module, an application processor module, a user information ...

Abstract

The invention provides a working method for a terminal by taking a personal handphone system (PHS) network as a sub-network of a third-generation mobile network. The system comprises a PHS / 3G dual-mode mobile terminal, a PHS network and a 3G mobile network. When a 3G user uses the dual-mode mobile terminal, and takes precedence to be accessed to the 3G mobile network, the 3G user takes precedence to be accessed to the 3G mobile network automatically; when the 3G user just has PHS wireless signals, the 3G user is accessed to the PHS network automatically and is interconnected with a 3G core network through a PHS core network, thus realizing user authentication and location update in the 3G core network; a calling is set up in the PHS core network, namely the PHS network serves as the sub-network accessed to the 3G network. The system and the terminal have the advantages of simple structure and practicability; the working method solves the problem of insufficient network coverage and difficult provision of communication services at the early stage of establishment of the 3G network; the roaming function is provided for PHS single-module terminals using 3G numbers; the working method provides better mobile communication services for users by using the existing PHS network after a fixed-line service provider obtains a 3G mobile license plate.

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...
