Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Based on the problems referred to above, the invention provides a kind of method for searching network of mobile terminal.
With reference to the schematic flow sheet that Fig. 1, Fig. 1 are the first embodiment of the method for searching network of mobile terminal of the present invention.
In the present embodiment, the method for searching network of described mobile terminal comprises:
Step S10, obtains the positional information that mobile terminal is current;
In the present embodiment, described mobile terminal comprises mobile phone, PDA (personal digital assistant), PAD (panel computer) etc.Described mobile terminal is for mobile phone, and when after mobile phone power-on, mobile phone needs to carry out SIM card and looks for net, and namely search for frequency, described frequency is the numbering to fixed frequency.Prestore in mobile phone need search frequency, described in prestore needs search frequency can the positional information current according to described mobile terminal determine.The current location information of described mobile terminal can be accurate positional information, also can be coarse positional information, described accurate positional information is the position obtained by the locating module of mobile terminal, or be the positional information by the community residing for mobile terminal, the described country of coarse positional information residing for mobile terminal, namely current mobile terminal uses in China, or use in the U.S., or current mobile terminal uses in Asia, or in European Area use etc.
Step S20, determines according to the described positional information obtained the frequency needing search;
After the positional information getting described mobile terminal, just can determine according to the described positional information obtained the frequency needing search, and not need to search for all frequencies.Described need the frequency of search can divide for all frequency ranges of China Mobile frequency, China Telecom all frequency ranges divide frequency, CHINAUNICOM the frequency that divides of all frequency ranges; Or be some frequency in the frequency that all frequency ranges of some frequency in the frequency that all frequency ranges of some frequency in the frequency that all frequency ranges of China Mobile divide, China Telecom divide, CHINAUNICOM divide; Or be the frequency that all frequency ranges of foreign operator divide; Or be some frequency in the frequency that all frequency ranges of foreign operator divide.
Step S30, carries out searching net process successively according to the described frequency obtained, until find can be resident frequency.
After getting the frequency needing search, carry out searching net process successively, until find can be resident frequency.Carrying out searching in the process of net process, because described frequency is the numbering to fixed frequency, namely described frequency has numbering, such as frequency 1, frequency 2, frequency 3 etc.Therefore can carry out successively searching net process according to the described order of the frequency point number of search that needs, namely preferential searching frequency 1 nets process, searches in current network whether there is frequency 1.Described mobile phone is searched net process and is specifically comprised the following steps:
