Embodiment Construction

[0052] In the mobile terminal of the prior art, in the process of starting up and searching for a network, the physical frequency information and system information of each frequency point are serially received according to the signal strength, so that the speed of network search is relatively slow, and for multi-card mobile terminals, this problem appears to be particularly prominent.

[0053] This technical solution receives the physical frequency information and system information of one or more other customer identification cards within the time interval when a certain customer identification card receives system messages, that is, receives the information of each frequency point in parallel, shortening the network search time, Increased search speed.

[0054] In order to make the above objects, features and advantages of the present invention more obvious and comprehensible, specific implementations of the present invention will be described in detail below in conjunction...

Abstract

The invention discloses a mobile terminal and a network searching method thereof. The network searching method for the mobile terminal comprises the following steps of: scanning signal strength of each frequency point; receiving physical frequency information and system information of a first frequency point according to the signal intensity, wherein the system information comprises a plurality of system messages; and at the intervals of the plurality of system messages, receiving physical frequency information and system information of at least another one frequency point according to the signal intensity. The network searching method shortens the network searching time and improves the network searching speed.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a mobile terminal and a network finding method thereof. Background technique [0002] With the rapid development of mobile communication technology, Global System for Mobile communication (GSM, Global System for Mobile communication) network has been widely used. GSM network users are identified by accessing a mobile terminal (such as a mobile phone) with a Subscriber Identification Module Card (hereinafter referred to as SIM card). Through the SIM card, users can become registered users of the network and enjoy the services provided by the network. Various services. After the mobile terminal is turned on, it needs to perform a network search process to search for the GSM network of the operator to which the SIM card belongs. [0003] The publication number is " CN101188835A " Chinese patent document discloses a kind of method that mobile phone boots and finds the network, ...
