Abstract
A method for authenticating terminals in a wireless communication service involves receiving registration requests from terminals requiring access, transmitting to each of the terminals a signalling channel assignment signal allocating a duplex signalling channel uniquely to each terminal, transmitting in the signalling channel an authentication request signal, receiving an authentication response signal in the channel, the contents of which depend on the context of the authentication request signal, and deciding whether to allow access to the system according to the contents of the authentication response signal.

An authentication method for determining whether to provide communication services to each of a plurality of wireless terminals, comprising:
- transmitting respectively to each of said terminals a unique signalling channel assignment signal, that indicates to that terminal a duplex signalling channel uniquely assigned to that terminal;
- transmitting to each of said terminals in said respective signalling channel a respective authentication request signal;
- receiving from each of said terminals in said respective signalling channel a respective authentication response signal, the contents of which are dependent on the contents of the authentication request signal;
- and
- determining whether to provide subsequent communication services to each of said terminals according to the contents of the authentication response signal received from that terminal.
A method of authentication for a wireless communications terminal, comprising:
- receiving a signalling channel assignment signal that indicates a duplex signalling channel uniquely assigned to that terminal;
- receiving an authentication request signal on said signalling channel;
- generating an authentication response signal on the basis of the content of said authentication request signal and identification information provided at the terminal;
- and
- transmitting said authentication response signal.
An authentication method for determining whether to provide communication services to each of a plurality of wireless terminals, comprising:
- allocating to each of said terminals a respective control signalling channel with a respective Quality of Service which is variable from one said signalling channel to another;
- and
- performing an authentication exchange with each of said terminals on the respective control signalling channels so as to determine whether to provide services to that terminal.
