Description of drawings
Fig. 1 is the system chart of preferred embodiment localisation of mobile terminals of the present invention.
Fig. 2 is the localization method process flow diagram of preferred embodiment localisation of mobile terminals of the present invention.
Whether Fig. 3 effectively reaches the particular flow sheet of the position location satellite information in the sky, base station that obtains current C ELL ID correspondence for the data in the memory module of judging among Fig. 2.
Embodiment
See also Fig. 1, preferred embodiment portable terminal of the present invention comprises a RIL (radio layer) module, a GPS module, a main control module and a memory module.
Design philosophy of the present invention is: the main control module of portable terminal is located last GPS the longitude that successfully obtains, latitude, height above sea level and LAC (lane place coding) and CELL ID (cell ID) are saved in the memory module, when later on portable terminal need position by reading the data in the memory module, the warp that last time is obtained, latitude and height above sea level carry out analyzing and processing as the GPS module that reference information is passed to portable terminal, in conjunction with the position location satellite information of portable terminal according to the sky, base station of the corresponding CELL ID of current LAC and CELL ID acquisition, thereby can dwindle the scope of search position location satellite and accelerate to search corresponding position location satellite, shorten the time of search of satellite, accelerate locating speed.
Specify the concrete position fixing process of the present invention than portable terminal below in conjunction with Fig. 2, the step of localization method shown in Figure 2 is as follows:
S201: locator data such as the main control module of portable terminal longitude that last GPS location is successful, latitude, height above sea level and LAC and CELL ID data storing are in memory module;
S202: in the time of need reorientating, the main control module of portable terminal judges whether the data in the memory module are effective earlier;
S203: if the data in the memory module are invalid, master control module controls GPS module directly starts the GPS positioning function;
S204: if the data in the memory module are effective, main control module sends the longitude in the memory module, latitude and height above sea level to the GPS module as reference information;
The position location satellite information in the sky of the base station of the current C ELL ID correspondence that the S205:GPS module obtains according to reference information search position location satellite and by the RIL module, thus time of search position location satellite shortened.
Judge data in the memory module whether effectively reach the sky, base station that obtains current C ELL ID correspondence position location satellite information idiographic flow as shown in Figure 3, idiographic flow shown in Figure 3 is as follows:
S301: the main control module of portable terminal obtains current LAC and CELL ID by the RIL module;
S302: the main control module of portable terminal sends to LAC in current LAC and CELL ID and the memory module and CELL ID the position determining entity of networking side in the GPRS mode;
S303: position determining entity feeds back to the position location satellite information in the sky, base station of two base station position informations of portable terminal and current C ELLID correspondence, comprises warp, the latitude of base station in the base station position information;
S304: whether two base station position informations of the main control module analysis of portable terminal are more or less the same, when the longitude of two base station position informations and latitude differ when 2 degree are following, think that then the position location satellite in the sky, base station is identical to small part, the data that are memory module are effective, otherwise, think that then the data of memory module are invalid.
More than about the description of pick-up unit and correlation parameter, be embodiments of the invention only, be not limited to the present invention, within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
