Radio interface switching method of smart phone

Abstract

The invention relates to a radio interface switching method of a smart phone. The method comprises the steps of: (1) collecting the eigenvalue of the current available wireless network; (2) calculating the cost function value of the current signaled wireless network by using cost function according to the eigenvalue of the wireless network; (3) selecting the wireless network with a large cost function value as the current access network according to the cost function value; (4) setting a feedback input parameter of the cost function, and setting application program and web sites to a black/white list; and (5) determining the specific location of the current application program or the web site in the black/white list, and the feedback input parameter of the cost function, and regulating the current access network. According to the radio interface switching method of smart phone provided by the invention, the method not only can be operated on a smart phone directly without adding extra facilities nor modifying the current network protocol so as to fully utilize the characteristics of heterogeneous wireless networks and to improve the user experience, but also can eliminate the influences of switching-caused network interrupt on the user experience.

Description

technical field [0001] The invention relates to the fields of mobile Internet and wireless communication, in particular to a method for switching wireless interfaces of smart phones. Background technique [0002] The current wireless environment for smartphones is a wireless communication environment in which multiple heterogeneous networks coexist, including cellular networks, digital video networks, wireless metropolitan area networks, wireless local area networks, home networks, personal networks, and so on. Moreover, these networks have many standards. For example, cellular networks include wireless access technologies such as W-CDMA, CDMA2000, TD-SCDMA, and GPRS. These heterogeneous wireless networks have different characteristics. For example, Wi-Fi has high network bandwidth and low cost, but the mobile support of terminal equipment is poor, the transmission distance is short, and energy consumption is relatively high, while GPRS / UMTS supports The mobility of the equ...

Problems solved by technology

However, no matter whether it is adding a mobile gateway facility or modifying an existing network communication protocol, it is necessary to realize the support of a large and complex project, and it is difficult to be compatible with the existing technology, and many aspects need to be reinvented

Therefore, these business continuity efforts cannot be implemented and deployed in the short term
