Embodiment Construction

[0054] The idea of ​​the present invention is to design a penalty function for each frequency point, and the penalty function is invalid at the initial moment; count the latest dwell time and switching flag of each frequency point; set the frequency point according to the switching flag and dwell time of the frequency point The penalty function, in each measurement period, the penalty function is updated, the penalty function decreases with the increase of the number of measurements, and decays to the initial state within a limited number of measurement periods; the measurement results are corrected on the basis of the penalty function; The final measurement result is compared with the preset threshold to determine whether to trigger the handover behavior; at the moment of handover judgment, the measurement result of each frequency point is corrected using the penalty factor, and compared with the preset handover threshold to determine whether to trigger the handover Behavior. ...

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...
