Embodiment Construction

[0033] At present, when the mobile terminal turns on the E-CID function, it usually needs to schedule the time to measure and read the system information of the neighboring cell by itself during the idle period of the current mode, and the base station will not specially set aside time for the mobile terminal to measure and read the neighboring cell The time of the system message. If the mobile terminal cannot successfully receive the system message during the idle period of the current mode, it usually needs to suspend receiving the signal of the current serving cell, switch the receiver to the frequency point of the neighboring cell, and according to its own software and hardware architecture Set the window length and window density to receive the system information of the neighbor cell. Because the mobile terminal sets the window length and window density according to its own software and hardware architecture, it is easy to cause the wireless link to be out of sync, especi...

Abstract

A mobile terminal and its positioning method. The method includes: receiving a request for obtaining positioning information generated by the positioning server according to the reported positioning capability information; according to the request for obtaining positioning information, obtaining corresponding positioning information from a pre-received system message, and reporting to the positioning server, and the positioning server locates the geographic location of the mobile terminal according to the reported positioning information, and the system message received in advance includes: when the mobile terminal cannot be idle in the current communication mode When the system message is successfully received within the period, the system message is received according to the preset window length and window density, and the preset window length and window density are related to the current communication mode of the mobile terminal and the system message to be received. The communication mode corresponding to the message is related. Applying the method can reduce wireless link connection failure and call drop when the mobile terminal applies the E-CID function.

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 applied, the mobile terminal receives system information of different neighboring cells multiple times, and then can obtain corresponding positioning information from the received system information, and send the positioning information to the positioning server, The geographic location of the mobile terminal is determined by the positioning server according to the positioning information reported by the mobile terminal. [0003] However, at present, when the mobile terminal uses the E-CID function, the wireless link connection failure often occurs, or even call drop occurs. Contents of the invention [0004] What the present invention aims to solve is how to reduce wir...
