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 discloses a network selection method and a device based on a country code, wherein the method comprises the following steps: when the network-searching mode of a wireless terminal subjected to startup is a dual-module or multi-module network-searching mode, judging whether a mobile country code of a network is a mobile country code of a specific country, if so, setting the network-searching mode as a 3G only mode, otherwise, maintaining the original network-searching mode. Compared with the prior art, by using the method and device disclosed by the invention, a limitation that a wireless terminal can carry out global search only according to frequency ranges is overcome, and a judgment can be performed according to mobile country codes so as to carry out dynamic adjustment, thereby shortening the network-searching time; and the report of useless information can be avoided, and the normal operation of the wireless terminal in a mode can be guaranteed.

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...
