A multi-network mode switching method and its communication device

Abstract

The invention discloses a method for switching the multi-network mode, which comprises the following steps: the measurement cycle is separated from the switching decision-making cycle and the switching decision-making cycle is adjusted according to the variation condition of the network, and a network mode switching threshold is dynamically and comprehensively adjusted according to the duration probability and / or network priority factor under different network modes so as to realize the switching between a plurality of network modes. The invention simultaneously discloses a multi-network-mode communication device, which comprises a network mode measurement module, a switching decision-making cycle setting and adjusting module, a network mode switching decision-making module and a network mode switching execution module. By providing a method for switching the multi-network mode and a communication device thereof, the invention ensures that the multi-network-mode communication device better adapts to the variation of the network conditions and simultaneously greatly solves the problems of network ping pong switching and imbalance of the network development in the staggered coverage areas of 2G and 3G, enhances the stability of the network resident and services and lowers the power consumption of the multi-network-mode communication device.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a multi-network mode switching method and a communication device thereof. Background technique [0002] With the rapid increase in the number of mobile users, the load of the mobile communication network is increasing, which leads to phenomena such as dropped calls, crosstalk, poor voice quality, and difficulty in accessing the Internet when communication terminals are prone to occur, thus making communication service quality severely affected. big impact. In response to this situation, a dual-mode communication terminal supporting both the second generation (2G, the Second Generation) network and the third generation (3G, the Third Generation) network has emerged. [0003] As a second-generation network with quite mature technology, the Global System for Mobile Communication (GSM, Global System for Mobile Communication) can easily provide local call functions, whil...

Problems solved by technology

Although this method is simple and easy to implement, because it lacks the necessary distinction between 2G and 3G network modes, and does not consider the network mode distribution of communication terminals, it is easy to switch over frequently and repeatedly in areas covered by 2G and 3G interlacedly, resulting in The waste of power consumption affects the standby performance of dual-mode communication terminals and also affects the stability of services

At the same time, this method does not make full use of the 3G network and give full play to the characteristics of the high communication rate of the 3G network, so it is not conducive to the stability and further expansion of 3G services
