Multimode switching method for heterogeneous network

Abstract

The invention discloses a multimode switching method for a heterogeneous network. The method mainly comprises the following steps of: determining a real-time service and a non-real-time service in each communication mode in the heterogeneous network, and determining priority among a plurality of communication modes in the heterogeneous network; setting respective packet loss threshold values of the real-time service and the non-real-time service in each communication mode; acquiring respective packet losses of the real-time service and the non-real-time service in each communication mode; and comparing the obtained packet losses and corresponding threshold values according to a sequence ranging from high propriety to low priority, and finding a current most proper access network for switching. Due to the adoption of the method, the current communication performance is sensed through a communication service, an optimal communication mode can be selected through a decision, a network resource can be effectively used by a user, and interrupt communication capability resistance is enhanced.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a multi-mode switching method of a heterogeneous network. Background technique [0002] Due to the rapid development of 3G and wifi, many places are covered by both 3G and wifi networks, and correspondingly, most mobile terminals have both 3G and wifi modules. When a mobile terminal is in an area covered by 3G and wifi at the same time, the traditional method will always give priority to the wifi network. This is because in general, the bandwidth of wifi is far better than that of 3G, and the communication quality is better than that of 3G, but Under special circumstances, the communication quality of wifi may be reduced to a very low level, or even lower than the communication quality in the case of 3G. At this time, the mobile terminal will still choose the wifi network. In view of this situation, in order to enable users to better use the current net...

Problems solved by technology

These two judgment strategies have certain one-sided and inflexible shortcomings. They only consider the access situation from the terminal to the access point, and ignore the network situation from the access point to the service server.

When the network from the access point to the service server is congested, but the signal strength and load of the access point itself do not change, these two strategies cannot perceive the real change of the communication network, and the mobile terminal cannot make a timely switching judgment
