The present invention overcomes the deficiencies in the prior art, the technical scheme that provides is: mobile communication terminal sends to mobile operator server by the USSD Location Request with the Cell-ID of its sub-district, current place, mobile operator server is inquired about its database, obtain this Cell-ID corresponding position information, by the USSD response message positional information is fed back to mobile communication terminal then.Technical scheme provided by the invention is compared existing GPS locate mode, realizes more simple and fast, and not needing or not the support of extra software and hardware through complex calculations yet.
Description of drawings
Fig. 1 is an embodiment of the invention flow chart.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Usually can both preserve the information of its current network in the mobile communication terminal, as LAC (location areacode, location area codes), Cell-ID ((Cell Identifier, cell ID) etc., wherein CellID is a cell ID, be used to identify the sub-district of the current place of mobile communication terminal network, be generally string number.Corresponding, mobile operator has associated databases to preserve the Cell ID and the corresponding position information of each sub-district usually.
When the user need obtain its current position information, can start the positioning function of mobile communication terminal, mobile communication terminal will be created a USSD request (to call the USSD Location Request in the following text), be used for to the mobile operator request position information.Specifically, mobile communication terminal at first reads Cell-ID from the current network information of storage, generates the USSD request according to this Cell-ID.The form of this USSD request is as " * #SC*n characters# ", and wherein " SC " is the service code of mark location request, specifically can be determined " n characters " Cell-ID for reading by mobile operator.
Mobile communications terminal with the MTK platform is an example, and the information of its current network is generally held in the following data structure body:
typedef?struct
{
14c?context_struct?*14c_ptr；
}layer4_context_struct；
extern?layer4_context_struct*layer4_ptr_g；
Mobile communication terminal can obtain its value: layer4_ptr_g-＞14c_ptr-＞hz_ptr-＞current_cell_id by pointer from above-mentioned data structure body when generating the USSD Location Request.
Mobile communication terminal arrives the USSD Location Request that generates the server of mobile operator by Network Transmission, the USSD Location Request of the server response mobile communication terminal of mobile operator, the server of mobile operator obtains the Cell-ID of sub-district, the current place of mobile communication terminal from the USSD Location Request, the querying server database, obtain this Cell-ID corresponding position information, convert this Cell-ID corresponding position information to the longitude and latitude data, then the longitude and latitude data are fed back to mobile communication terminal.
The server of mobile operator can adopt ReleaseComplete (release is finished) message, as the response to the USSD Location Request when mobile communication terminal feedback longitude and latitude data.Handle for making this response message be different from other USSD and being convenient to mobile communication terminal identification, can add the character of some home position information therein,, specifically can consult to determine by mobile operator and terminal equipment manufacturer as * A*L.The content format of longitude and latitude can be: 3256.55N, 1133.43E.
According to 3GPP (3rd Generation Partnership Project, third generation partner program) agreement, Release Complete message is made up of 4 parts:
1, Protocol discriminator agreement difference;
2, Transaction identifier behavior identifier;
3, Message Type type of message is xx101010 as this part, then is expressed as ReleaseComplete message;
4, other optional information fields.
Other optional information fields wherein comprise Cause and Facility information element, the word string of longitude and latitude data directly can be added as ussd-string among the Facility, be about to " * A*L3256.55N, 1133.43E " and mail to mobile communication terminal as message body.
After mobile communication terminal is received Release Complete message, message body is resolved, be * A*L as beginning among the ussd-string, what then can confirm to return is the longitude and latitude data, and " L3256.55N, 1133.43E " is latitude and longitude coordinates.
Concerning domestic consumer, the longitude and latitude data are not directly perceived, for making the user obtain more intuitive current location information, the longitude and latitude data of returning can be associated with the electronic chart application program, be about to the electronic chart application program that the longitude and latitude data pass to mobile communication terminal, the electronic chart application program is labeled in current location on the map according to the longitude and latitude data, and the user interface by mobile communication terminal shows then.
The flow chart of the embodiment of the invention specifically comprises following step as shown in Figure 1:
1, the user starts the positioning function of mobile communication terminal, and mobile communication terminal reads Cell-ID from the current network information of its storage;
2, mobile communication terminal generates the USSD Location Request, carries the Cell-ID of sub-district, the current place of mobile mobile communication terminal in this USSD Location Request;
3, the USSD Location Request of mobile communication terminal generation sends to mobile operator server;
4, mobile operator server receives this USSD Location Request, inquires about its database, obtains Cell-ID corresponding position information in this USSD Location Request;
5, mobile operator server converts positional information to the longitude and latitude data, and the longitude and latitude data are arrived mobile communication terminal by Release Complete message feedback;
6, mobile communication terminal parses latitude and longitude coordinates from Release Complete message, and the latitude and longitude coordinates that parses is transferred to the electronic chart application program;
7, the electronic chart application program is labeled in current location on the map according to the longitude and latitude data, and the user interface by mobile communication terminal shows then.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
