Problems solved by technology

In the case that the lost mobile station is used in a different service provider's network or with a different SIM card, then traditional tracking methods cannot track the lost mobile station
Moreover, traditional tracking methods only identify who is using the lost mobile station, and do not limit the use of the mobile station

Abstract

Provided is a method for tracking a lost mobile station. The method includes, when a replacement Subscriber Identity Module (SIM) card is installed , determining whether the replacement SIM card is registered as a licensed replacement SIM card; when the SIM card is not registered, transmitting a previously stored tracking short message to a preset destination; and upon receipt of a tracking response short message, setting a tracking lock mode for limiting a use of some functions of the mobile station.

Description

technical field [0001] The present invention relates generally to mobile stations and, in particular, to a method for tracking a mobile station when it is lost. Background technique [0002] Typically, a Serving General Packet Radio Service (GPRS) Support Node (SGSN) or Mobile Services Switching Center (MSC) sends a Subscriber Identification Request to a mobile station when a subscriber is identified. In response to this, the mobile station sends a Subscriber Identification Reply to one of the SGSN or MSC. When one of the SGSN or the MSC decides to check the International Mobile Equipment Identity (IMEI) for the Equipment Identity Register (EIR), send the check IMEI to the EIR. The EIR replies to one of the SGSN or MSC by checking the IMEI confirmation. [0003] Conventional mobile communication systems attempt the following methods to track down a lost mobile station using the identification process described above. The owner of the mobile station manually reports the lo...
