发明名称 METHOD FOR TRACKING A MOBILE DEVICE ONTO A REMOTE DISPLAYING UNIT
摘要 <p>The present invention refers to a method for tracking at least one mobile device (10) onto a remote displaying unit (20) through a mobile switching center (30) connected to the mobile device (10) by a wireless communication network (1 ) and through a head-end (40) linked to the mobile switching center (30) and connected to the displaying unit (20) by a second communication network (2) different to the wireless communication network (1). The mobile device (10) is identified by a mobile device identifier IDM. The displaying unit (20) is identified by a displaying unit identifier IDDisp and is provided with a module (22) for processing messages coming from the head-end (40) identified by a head-end identifier IDHE. The mobile device (10) is provided with a locating unit (16) able to determine its current location and with a communication unit (12) for supporting at least an instant messaging service. The method comprising: a) an initialization phase including the steps of: - generating a key K and encrypting it with a password PW shared between the displaying unit (20) and the mobile device (10), - setting up, in a memory (13) of the mobile device (10), a first record R1 IDdisp referring to the displaying unit identifier IDDisp and comprising, the head- end identifier IDHE and the key K, b) an operating phase including the steps of: - determining the current location of the mobile device (10) and encrypting the current location by using the key K, - transmitting the mobile device identifier IDM and the encrypted current location to the displaying unit (10) by sending a message successively addressed to the mobile switching center (30), to the head-end (40) and to the displaying unit (20) by means of their respective identifiers, - decrypting the encrypted current location with the key K and displaying this location onto the displaying unit (20).</p>
