Abstract

An embodiment of the invention discloses a method for optimal selection between a WiFi (wireless fidelity) network and a TD-SCDMA (time division-synchronous code division multiple access) network. The method includes that user equipment detects a signal of the WiFi network; the user equipment requests for establishing a connection with the TD-SCDMA network when the intensity of the signal of the WiFi network is lower than -83db; the user equipment requests for establishing a physical connection with WiFi equipment when the intensity of the signal of the WiFi network is higher than -83db, an authentication request is initiated to the WiFi equipment, the connection between the user equipment and the WiFi equipment is established if authentication is successful, and a core network judges whether the user equipment needs to be switched from the WiFi network to the TD-SCDMA network or not; and the intensity of signals of the WiFi network is detected in every five seconds if the user equipment is successfully connected with the TD-SCDMA network. The method has the advantage that the optimal selection between the WiFi network and the TD-SCDMA network is realized.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of communication, and in particular relates to an optimal method between a WiFi network and a TD-SCDMA network. Background technique [0002] The interconnection and intercommunication of various heterogeneous networks is the main feature of the future communication network. The general packet radio service (General Packet Radio System, hereinafter referred to as GPRS) and the Time Division-Synchronous Code Division Multiple Access technology (Time Division-Synchronous Code Division Multiple Access, hereinafter TD-SCDMA)-based mobile communication network can provide large-scale network coverage, and Wireless Fidelity (hereinafter referred to as WiFi) wireless local area network, as a high-speed wireless network, is gaining more and more popularity in some hotspot areas. application. The mobile user equipment often detects multiple types of wireless network covers at the same time ...
