Method and system for tracking mobile communication device using instant messaging
First Claim
1. A method for tracking a mobile communication device having an IM function, comprising the steps of:
- activating selectively a tracking control mode if there is a request for configuring the tracking control mode to perform a function enabling tracking of the mobile communication device;
checking under the activated tracking control mode whether a SIM (Subscriber Identity Module)/USIM (User Services Identity Module) card has been changed; and
automatically sending a pre-stored IM (instant message) to a predefined destination mobile communication device in the background when a non-authenticated SIM/USIM card has been detected.

Abstract
Provided is a method for tracking any mobile electronic device which accesses wireless or wired network using Instant Messaging (IM). The mobile device, capable of instant messenger (IM) functionality, allows storage of one or more IM IDs in a separate non-volatile memory. When the mobile device is lost/stolen, and another person changes the SIM card, the phone verifies if the SIM card is the same as that of the owner by matching the IMSI numbers of the two. If there is a mismatch, the mobile device triggers the tracking feature. The tracking feature automatically and stealthily transmits instant messages to the stored messenger IDs. Furthermore, with video/voice capability in the IM client, there is a provision for transmitting live video/voice of the person using the mobile phone after the tracking feature is enabled as video calls or voice calls respectively.
