Embodiment Construction

[0024] First define some basic concepts. For a dual-mode terminal, the prior art specifies a network mode in which it resides preferentially. In the embodiment of the present invention, the mobile communication network corresponding to the network mode is referred to as a preferential camping network; for a dual-mode terminal, the current The prior art also stipulates the network mode for carrying the voice service preferentially. In the embodiment of the present invention, the mobile communication network corresponding to the network mode is called the voice service priority bearer network; for dual-mode terminals, it is also specified in the prior art In order to give priority to carrying the network mode of its data service, the mobile communication network corresponding to this network mode is called a data service priority bearer network in the embodiment of the present invention. In general, the preferential camping network and the preferential bearer network for data se...

Abstract

The invention discloses a network reselection method of a dual-mode terminal and dual-mode terminal equipment. The invention is used for solving the following problems: the existing dual-mode terminal has larger system resource consumption, intercell interference is enhanced, the system capacity is reduced, etc in the process of network reselection. The method comprises the following steps: the dual-mode terminal measures the signal strength of the current serving cell when receiving the channel release information transmitted by a first network after the current service is completed; the dual-mode terminal measures the signal strength of a second network cell adjacent to the current serving cell when judging that the signal strength of current serving cell exceeds the reselection start measuring threshold among inter systems; and the dual-mode terminal reselects and enters into the second network when at least one signal strength exceeds the second network cell of the reselection judgment threshold. The method can effectively reduce the system resource consumption of the dual-mode terminal in the process of network reselection, reduce intercell interference and improve the system capacity, thus improving the service quality.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a network reselection method for a dual-mode terminal and dual-mode terminal equipment. Background technique [0002] Currently, the digital mobile communication system with the largest commercial scale and the widest coverage in the world is GSM (Global System for Mobile Communication, Global System for Mobile Communication). The GSM system is generally called a 2G (the 2nd Generation Mobile Communication, second generation mobile communication) system. With the continuous development of mobile communication technology, the 3G (The 3rd Generation Mobile Communication, third generation mobile communication) system adopting CDMA (Code Division Multiple Access, Code Division Multiple Access) technology has also entered or will enter a commercial stage. The 3G system takes WCDMA (Wideband CDMA, broadband CDMA) standard, TD-SCDMA (Time Division-Synchronous CDMA, time di...
