Method for tracking a mobile device onto a remote displaying unit
First Claim
1. A method for tracking at least one mobile device on a remote displaying unit through a mobile switching center connected to the mobile device by a wireless communication network and through a head-end linked to the mobile switching center and connected to the displaying unit by a second communication network different from the wireless communication network, said mobile device being identified by a mobile device identifier, said remote displaying unit being identified by a remote displaying unit identifier and being provided with a module for processing messages coming from the head-end identified by a head-end identifier, said mobile device being provided with a locating unit able to determine a current location of the mobile device and with a communication unit for supporting an instant messaging service, said method comprising:
- performing an initialization phase comprising;
generating a key and encrypting the key with a password shared between the remote displaying unit and said mobile device; and
storing, in a memory of said mobile device, a first record referring to the displaying unit identifier and comprising the head-end identifier and said key;
performing an operating phase comprising;
determining the current location of the mobile device and encrypting by the mobile device the current location by using the key;
transmitting, by the mobile device, the mobile device identifier and the encrypted current location to the displaying unit by sending a message successively addressed to the mobile switching center, to the head-end and to the remote displaying unit by means of their respective identifiers; and
decrypting the encrypted current location with the key and displaying said location on the remote displaying unit.

Abstract
The present invention refers to a method for tracking at least one mobile device onto a remote displaying unit through a mobile switching center connected to the mobile device by a wireless communication network and through a head-end linked to the mobile switching center and connected to the remote displaying unit by a second communication network different to the wireless communication network. The mobile device is identified by a mobile device identifier. The remote displaying unit is identified by a remote displaying unit identifier and is provided with a module for processing messages coming from the head-end identified by a head-end identifier. The mobile device is provided with a locating unit able to determine its current location and with a communication unit for supporting at least an instant messaging service.

16. A method for enabling tracking of a mobile device comprising:
-
storing, by the mobile device in a memory of the mobile device, a first record referring to a remote displaying unit identifier identifying a remote displaying unit, the first record comprising a head-end identifier identifying a head-end and a key, the key being encrypted with a password shared between the remote displaying unit and the mobile device, the mobile device being connectable to the remote displaying unit through a mobile switching center connectable to the mobile device by a wireless communication network and through the head-end, which is linked to the mobile switching center and connectable to the remote displaying unit by a second communication network different from the wireless communication network, the mobile device including a locating unit capable of determining a current location of the mobile device, the mobile device further being provided with a transceiver for supporting at least an instant messaging service; determining by the mobile device a current location of the mobile device by the locating unit of said mobile device and encrypting by the mobile device the current location using the key; and transmitting by mobile device the mobile device identifier and the encrypted current location to the remote displaying unit by sending a message successively addressed to the mobile switching center, to the head-end and to the remote displaying unit by means of their respective identifiers; whereby the remote displaying unit may decrypt the encrypted current location with the key and display said location on the remote displaying unit. - View Dependent Claims (17)
