Embodiment Construction

[0024] Since 3GPP defines its own country code for each country in the definition process, and the network of each country has its own characteristics, such as Japan, its network is very developed, and network operators hope that users should try their best to use the 3G network. Since the wireless communication network has a unique network identifier, the mobile network identifier is composed of a mobile country code and a mobile network code. The mobile country code is the country to which the wireless communication network belongs, and the mobile network code is the network identifier of the network in the country. All networks in a country have the same mobile country code. Due to the above features, the terminal device can set an appropriate network search mode by reading the mobile country code.

Abstract

The invention proposes a network selection method and device based on a country code. When the network search mode after the wireless terminal is turned on is dual-mode or multi-mode network search mode, judge whether the mobile country code of the network is the mobile country code of a specific country, if yes, set the network search mode to 3G only mode, if not Then maintain the original network search mode. Compared with the prior art, by adopting the method and device of the present invention, the limitation that the wireless terminal can only conduct global search according to the frequency band can be changed, and it can be dynamically adjusted according to the judgment of the mobile country code, which shortens the time for finding the network; at the same time, it can avoid The reporting of useless information ensures that the wireless terminal works normally in one mode.

Description

technical field [0001] The present invention relates to the technical field of communications, and more particularly, to a method and device for network selection based on country codes. Background technique [0002] Due to the extensive development of 3G wireless technology, operators and users have higher and higher requirements for wireless terminals. However, at the beginning of the establishment of wireless communication, global seamless compatibility is required. At present, the number of 3G frequency bands in the world has increased to 16 frequency bands. In addition to the 4 common frequency bands of 2G, the requirements for terminals are getting higher and higher, but with the increase of frequency bands, the time to find the network will become slower and slower. How to reduce user waiting and how to quickly register the network is A research direction for operators in various countries. [0003] Due to the particularity of 3G networks in some countries such as Ja...
