Embodiment Construction

[0034] At present, when the mobile terminal activates the E-CID function, it needs to switch to the frequency point of the corresponding cell multiple times, and then can receive the system information of the cell to obtain corresponding positioning information. Since the positioning information of different neighboring cells is carried in different system messages, power consumption increases. Moreover, in practical applications, there is a certain time delay from when the mobile terminal turns on the E-CID function to when the acquired positioning information is reported to the positioning server, so that the positioning server cannot provide real-time information on the mobile terminal. to locate.

[0035] In view of the above problems, an embodiment of the present invention provides a positioning method for a mobile terminal. The method allows the mobile terminal to preset a positioning information database, and then when receiving a request for obtaining positioning infor...

Abstract

The invention relates to a mobile terminal and a positioning method thereof. The method comprises the following steps of receiving a positioning capability reporting request sent by a positioning server; according to the positioning capability reporting request, reporting positioning capability information to the positioning server; receiving a positioning information obtaining request generated by the positioning server according to the reported positioning capability information; and, according to the positioning information obtaining request, obtaining corresponding positioning information from a pre-set positioning information database, reporting the corresponding positioning information to the positioning server, and positioning the geographical position of the mobile terminal by the positioning server according to the reported positioning information, wherein the positioning information in the positioning information database is obtained by recording system messages of cells, where the mobile terminal lingers. By means of the method, the mobile terminal can be positioned rapidly; and furthermore, the power consumption of the mobile terminal can be reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a mobile terminal and a positioning method thereof. Background technique [0002] Currently, most mobile terminals have an enhanced cell ID (Enhanced Cell ID, E-CID) function. When the E-CID function is turned on, the mobile terminal can receive system information of different neighboring cells, and then can obtain corresponding positioning information from the received system information, and send the positioning information to the positioning server, by The positioning server determines the geographic location of the mobile terminal according to the positioning information reported by the mobile terminal. [0003] However, since the positioning messages of different neighboring cells are carried in different system messages, in order to obtain the positioning information of the corresponding cell, the mobile terminal needs to receive the system messages multiple times, ...
