Abstract

A method is disclosed of updating the software of a GSM or equivalent mobile telephone terminal via a base transceiver station in whose coverage area the terminal is located and using data supplied by a programming platform operating at the level of a server center to which the base transceiver station is connected in a fixed telecommunication network. The terminal is updated by a transparent exchange of SMS or equivalent mobile telephone messages at the initiative of the programming platform and in cooperation with the server center.

Claims

1. A method of updating the software of a GSM or equivalent mobile telephone terminal via a base transceiver station in whose coverage area said terminal is located and using data supplied by a programming platform operating at the level of a server center to which said base transceiver station is connected in a telecommunication network, data for updating said terminal being transferred by an exchange of mobile telephone short messages, e.g. SMS, at the initiative of the programming platform and in cooperation with said server center, in which method said exchange of mobile telephone short messages comprises prior messages for reciprocal authentication of said terminal and said platform.

2. The method claimed in

claim 1

wherein an exchange for updating a terminal includes the following operations:

sending said terminal an MT type agent wake-up short message which includes a header characteristic of updating and data for said terminal to call back said platform,

said terminal sending said platform an MO type acknowledgement short message after receiving a wake-up message, said acknowledgement preferably containing the call number of said terminal and a synthetic definition of the present hardware and/or software configuration of said terminal, and

sending the terminal one or several successive MT type messages for transmission of the updating information, said transmission including said update data preceded by said update header and by the new synthetic configuration definition resulting from the update.

3. The method claimed in

claim 2

wherein the data transmitted by said platform to said terminal for an update also includes said synthetic configuration definition received from said terminal.

4. The method claimed in

claim 1

wherein said terminal sends an MO type update acknowledgement message after the update and this message preferably includes the call number of said terminal accompanied by the new synthetic configuration definition received in the context of the update.

5. A GSM or equivalent type mobile radio terminal including software for implementing a method as claimed in any of

claims 1
