Problems solved by technology

[0006] When the mobile terminal starts up or selects a network after being disconnected from the network, it always selects the RPLMN network and the last registered RAT network (except for the case where the user manually selects the network when the mobile terminal is powered on), and cannot quickly select the available RAT network according to the characteristics of the network. This may prolong the time that the mobile terminal is not in the service area, and cannot fully enjoy the special services of different networks

Embodiment Construction

[0035] The core idea of ​​the method of the present invention is: set the PLMN network and the preferred RAT network information for the PLMN network for the mobile terminal network selection; when the mobile terminal needs to select the network, the mobile terminal obtains the PLMN network and the preferred RAT network information to search .

[0036] The preferred RAT network includes: an overlay preferred RAT network, a service preferred RAT network and a user preferred RAT network.

[0037] The coverage preferred RAT network, service preferred RAT network and user preferred RAT network described in the present invention are described below.

[0038] Coverage preferred RAT network: Among the multiple sets of RAT networks built by the operator using the same PLMN ID, one RAT network has the widest coverage area. This RAT network should be the preferred network when the mobile terminal is disconnected. This RAT network called an overlay preferred RAT network;

Abstract

The invention relates to a method for selecting network of mobile terminal. Wherein, it is characterized in that: setting PLMN network and the preference RAT network information based on PLMN network for the network selection of mobile terminal; when the mobile terminal selects network, it can obtain said PLMN network and preference RAT network information to search; the invention also discloses a relative mobile terminal. With said invention, the mobile terminal can select useful RAT network according to the network character, to reduce the time that the mobile terminal not in the service section and enjoy the character services of different networks.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for selecting a network by a mobile terminal and the mobile terminal. Background technique [0002] During the evolution of 2G (The Second Generation, second generation) mobile communication system to 3G (The Third Generation, third generation) mobile communication system, operators use the same PLMN (Public Land Mobile Network, public land mobile communication network) ID (Identification) has built multiple sets of RAT (Radio Access Technology, wireless access technology) networks, such as the GSM network of the 2G system, the WCDMA, CDMA2000, and TD-SCDMA networks of the 3G system, etc., hoping that mobile terminal users can enjoy the richness of 3G services, while enjoying the wide coverage of 2G in areas with poor 3G coverage. Both dual-mode and multi-mode mobile terminals provide automatic and manual network selection methods, enabling mobile terminal...
