Abstract
A multi user communications terminal apparatus providing simultaneous access for a plurality of users to a communications network in which the geographical locations of each user are registered and periodically updated, the terminal apparatus comprising a plurality of user terminals (320) each including electroacoustic transducers (34,36); and a common RF unit (304) comprising a shared RF amplifier (342) for coupling to a shared antenna system (302), in which the terminal apparatus comprises means (348) for transmitting common location updating signals, and is arranged not to transmit separate location update signals for every one of said users.
Claims14
A multi user communications terminal apparatus providing simultaneous access for a plurality of users to a communications network in which the geographical locations of each user are registered and periodically updated,
- the terminal apparatus comprising a plurality of user terminals (320) each including electroacoustic transducers (34, 36);
- and a common RF unit (304) comprising a shared RF amplifier (342) for coupling to a shared antenna system (302),
- in which the terminal apparatus comprises a transmitter (348) for transmitting common location updating signals, and is arranged not to transmit separate location update signals for every one of said users;
- further comprising a control device coupled to control the power supplied by the shared amplifier,
- wherein on attempted initiation of an outgoing call by a user, the apparatus is arranged to determine whether sufficient power would be available to continue communication with said network if a call were set up, and is arranged not to complete the call unless sufficient power would be available.
A vehicle including apparatus providing simultaneous access for a plurality of users each identifiable by a respective subscriber identification module to a mobile communications network in which geographical locations of each user are registered and periodically updated,
- the apparatus comprising a plurality of user terminals each including electroacoustic transducers and a subscriber identification module reader;
- and a common RF unit comprising a shared amplifier for coupling to a shared antenna system,
- in which the apparatus comprises a transmitter for transmitting common location updating signals, and is arranged not to transmit separate location update signals for every one of said users
- further comprising a control device coupled to control the power supplied by the shared amplifier,
- wherein on attempted initiation of an outgoing call by a user, the apparatus is arranged to determine whether sufficient power would be available to continue communication with said network if a call were set up, and is arranged not to complete the call unless sufficient power would be available.
