A multi-network mode switching method and its communication device

Abstract

The invention discloses a multi-network mode switching method. The nearest residence time and the switching sign of each frequency point are counted; the penalty function of the frequency point is arranged according to the switching sign and the residence time of the frequency point, the penalty function is updated in each measuring period, and the measuring result is amended based on the penalty function; the measuring result after being amended is compared with the presetting threshold to judge whether a switching action is touched off or not. At the same time, the invention also discloses a multi-network mode communication device which consists of a network mode measurement module, a switching sign setting module, a penalty factor setting module, a RSSI amendment module, a network mode switching judging module, a network mode switching performing module and a penalty frequency point set updating module. Through providing the multi-network mode communication device and the switching method thereof, the invention reduces the probability of pointless switching, effectively prevents fake signals which are unsuitable to reside from influencing the stability of the system, and improves the stability of the network residence and the service.

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...
