Abstract: An electronic component with supervised communication modules has: —at least two communication modules functioning in parallel; and —a microprocessor-free supervisor. Each communication module has a step for interfacing with the supervisor, thus enabling the latter to use a data format common to all the modules. The supervisor is configured to deterministically manage access to a database on the basis of a configuration table and requests to read from and/or write to the database, from the communication module.

Abstract: The present invention relates to a message transmission system comprising a telecommunication network (2) comprising a communication server (4) and at least one wireless telephone (1), the server comprising means for sending messages to one or more wireless telephones, the wireless telephone or telephones (1) being equipped with means for storing and processing message (Mess-Serv), characterized in that the messages (Mess-Serv) comprise a first field (V-TYP) containing information relating to the type profile of the recipient of the message and in that the processing means compare the profile stored in each wireless telephone relative to the subscriber using the wireless telephone to the profile contained in the message, and authorize the storage of the messages in the storage means if the profile of the subscriber using the wireless telephone is compatible with the type profile contained in the field of the message.
