摘要:
A base station of a radiocommunication system has at least two antennas and can select one of the antennas. It determines if a channel to transmit to at least one mobile station is unidirectional and switches from one antenna to another in accordance with a predetermined random or pseudo-random law if the channel to transmit is unidirectional.

A method of securing the use of a mobile telecommunication terminal comprising a (U)SIM card reader includes a terminal initialization step consisting of requesting the user to enter a personal password after inserting a (U)SIM card into the terminal and storing the password in the (U)SIM card and in memory in the terminal. On the occasion of subsequent uses the password is verified either against the password stored in the card or against the password requested of the user, and operation of the terminal is disabled in the event of a mismatch. Applications include mobile telecommunication terminals.
摘要:
The invention provides a system for dynamic distribution of processing time during a frame in a station operating in time-division multiple access mode. The system comprises a set of N independent configurable processing resources respectively associated with N time windows in the frame, where N is a predetermined integer greater than 1. The N configurable processing resources can be configured to yield N respective configured processing resources each of which is activated for a respective particular processing operation for which it has been configured. Each of the N previously configured configurable processing resources is activated so that the respective particular processing operations are effected during the frame.
