Abstract

The invention provides a communication network searching method and electronic equipment. The communication network searching method is used in the electronic equipment. The method comprises the steps that according to a preset first searching strategy, a communication network with a first network mode is subjected to searching until system information with country codes is obtained; the country codes in the system information are obtained; according to the obtained country codes, a preset database is checked, so that corresponding second searching strategies are obtained, the database comprises the multiple second searching strategies, and each second searching strategy corresponds to a country code; and according to the second searching strategies, a communication network which is suitable for the electronic equipment and has a second network mode is subjected to searching.

Description

technical field [0001] The present invention relates to the field of electronic equipment, and more particularly, the present invention relates to a communication network search method and electronic equipment. Background technique [0002] With the development of mobile communication technology, the second generation communication network (2G), the third generation communication network (3G), the fourth generation communication network (4G) and so on have appeared. These communication networks currently coexist, and mobile terminals such as cell phones are compatible with various communication networks. [0003] In addition, in each communication network, different technologies use different frequency bands. For this reason, mobile phones need to support more and more frequency bands. For example, China Mobile even proposes mobile phones with 5-mode and 13-frequency requirements. In addition, for example, LTE frequency bands have been allocated more than forty LTE frequenc...
