Method, system and device for switching networks of mobile terminal

Abstract

The invention discloses a method, a system and a device for switching networks of a mobile terminal, aiming at solving the problem that the method for switching networks of mobile terminal affects the efficiency of the mobile terminal in a current packet domain service in the prior art. The method comprises the following steps: a network side device judges that PCCPCH (primary common control Physical Channel) RSCP (received signal code power) reported by the mobile terminal is less than a signal power valve value and the current service of the mobile terminal is a packet domain service, the network sides judges whether to inform the mobile terminal of switching networks from a 3G (The 3rd Generation Telecommunication) communication network to a 2G (The 2rd Generation Telecommunication) communication network based on the current experience quality metric of the mobile terminal. In the embodiment of the invention, when the mobile terminal executes a pocket domain service at present, the network side device judges whether to inform the mobile terminal of switching networks according to the PCCPCH RSCP and the current experience quality metric of the mobile terminal, so that the mobile terminal is capable of accurately switching networks and the efficiency of the mobile terminal in the packet domain service is improved.

Description

technical field [0001] The present invention relates to the field of mobile communications, and in particular, to a method, system and device for network switching by a mobile terminal. Background technique [0002] With the development of the third-generation communication technology (3rd Generation, 3G), users can obtain more abundant and higher-speed business services through the 3G communication network. In the initial stage of 3G communication network construction, since the 3G communication network has not achieved continuous coverage, the 3G communication network must rely on the second generation (Second Generation, 2G) network to achieve the ability to provide continuous services to users. Therefore, in the process of performing services for mobile terminals, switching from a 3G communication network to a 2G communication network has become an important issue. The 2G communication network includes the Global System for Mobile Communications (GSM) network, the Genera...
