Embodiment Construction

[0072] 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 with reference to the accompanying drawings and examples.

[0073] The wireless network system supporting dual-mode terminal access and its service access method of the present invention adds a mobile relay station (MRS) terminal to the system, and adopts the wireless ad hoc network (AdHoc) technology of a broadband wireless network to enable dual The modular terminal can switch among the three working modes of cellular network access mode, broadband wireless access mode, and Ad Hoc mode. When the dual-mode terminal performs business through the broadband wireless access mode, when it needs to switch modes, it does not directly switch to the cellular network access mode, but switches to the Ad Hoc working mode, and accesses through the added MRS terminal in the system. Go to other base stations and continue the ...

Abstract

In the invention, a mobile relay station is added into the system; the radio self-networking mode is set in the dual-mode mobile terminal; as required, the dual-mode mobile terminal is switched into the radio self-networking mode from cellular network access mode or wideband radio access mode; under the radio self-networking mode, the dual-mode mobile terminal accesses the base station of mobile wideband radio access network or the base station of cellular network; the mobile relay station is used in relaying information between the dual-mode mobile terminal and the base station of wideband radio access network or the base station of cellular network, under the self-networking mode.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless network system supporting dual-mode terminal access, a handover method and mobile transfer station equipment. Background technique [0002] With the IP-based network, the cellular mobile network is developing towards All-IP (ALL-IP); various broadband access technologies, such as wireless local area network (WLAN), wireless metropolitan area network (WMAN) and mobile broadband wireless access ( MBWA), etc., are based on IP technology. Although data services are developing rapidly, voice services are still the most important and common. The traditional circuit-switched mobile voice service will be replaced by the voice over wireless packet service (VoIPoW); although the broadband access technology is aimed at the data service, it is necessary to support the voice service. [0003] VoIPoW introduces the flexibility of IP, but it is not as good as traditi...
