Network switching method and terminal for supporting network switch

Abstract

The embodiment of the invention discloses a network switching method and a terminal for supporting network switch, and relates to the technical field of communication and aims to improve the switch efficiency of terminal between networks. The method comprises the following steps that: during switching of the terminal from a first network to a second network, the terminal transmits a request for entering an idle mode to the first network, ensuring that the first network saves the authentication information of the terminal and enabling the terminal to enter the idle mode; during switching of the terminal from the second network to the first network, the terminal switches a radio frequency from the second network to the first network and directly accesses the first network again. The embodiment of the invention is mainly applied to a network switching technology.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for network switching and a terminal supporting network switching. Background technique [0002] There are many wireless broadband access technologies, among which WiFi (Wireless Fidelity) technology and WiMAX (Worldwide Interoperability for Microwave Access) are two more important ones. Among them, the WiFi network has fast network deployment speed, low cost, high bandwidth, and does not require authorization when using spectrum, but the coverage area is small; while the WiMAX network covers a large area, but due to the large area, there are many access users and the average user bandwidth is narrow. Therefore, in practical applications, the WiFi network is usually used as a supplement to the WiMAX network, and WiFi hotspots are used in places with weak indoor WiMAX signals or densely populated places. [0003] For this reason, how to access the WiMAX network th...

Problems solved by technology

Since the process of switching from the WiMAX network to the WiFi network and then from the WiFi network to the WiMAX network may take a very short time, if the above switching method is used, the target access network must be updated every time the network is switched. If the terminal is authenticated, this will undoubtedly reduce the efficiency of the terminal switching between networks, and the frequent authentication process increases the burden on the network

In addition, the coverage area of ​​WiFi network is small and the signal attenuation is fast. When the terminal moves quickly, it may be too late to start the handover process when the WiFi network signal is found to be poor, resulting in handover failure and seamless business continuity. ensure
