Below referring to Fig. 2, one specific embodiment of localization method of mobile terminal of the present invention includes：
Whether the type for the 201st, determining the second Radio Access Network of mobile terminal connection is default wireless packet switched network type；If so, then performing step 202, step 203 is performed；
In the specific implementation, default wireless packet switched network type can include：Forth generation mobile communication technology (the Generation mobile communication technology of the 4,4G) network, Long Term Evolution (Long Term Evolution, LTE) network, HRPD (evolved High Rate Packet Data, eHRPD) network of evolution etc..The wireless packet switched network of preset kind generally has the characteristics of transmitted data rates are fast or with there is the characteristics of certain probability cannot connect to location-server.
202nd, location-server is accessed by the second Radio Access Network to be positioned, and the time-out time that mobile terminal is accessed into location-server by the second Radio Access Network was set to for the second time；
203rd, the time-out time that mobile terminal accesses location-server by the second Radio Access Network is the very first time.
In the specific implementation, the second time was less than the very first time, the very first time can be the time-out time that location-server is accessed by the first Radio Access Network of acquiescence, and this time would generally be long.For example, can be 10 seconds by the second set of time, certain second time may be arranged as the time that other are less than the very first time when the very first time is 30 seconds.
When the type of the second Radio Access Network is default wireless packet switched network type, because the second Radio Access Network now has the characteristics of transmitted data rates are fast, therefore selection accesses location-server by the second access network and positioned.In this case, if mobile terminal can be connected correctly to location-server, so mobile terminal can quickly realize positioning, there is certain probability to cannot connect to location-server additionally, due to the second Radio Access Network now, so will also access the smaller of the time-out time setting of location-server, if mobile terminal can not be accessed location-server completion positioning by the second Radio Access Network and (such as cannot connect to location-server, or location-server does not have accurate base station position data storehouse), so due to time-out time set it is smaller, mobile terminal can be positioned with fast fallback to other positioning methods (such as ephemeris extension positioning method) upon timing-out, so as to realize quick positioning.
