ABSTRACT:
A method of granting, to a user communications device, access to a service provided by a plurality of service communications devices where an access key code is generated during an initial communications session between the user communications device and one of the service communications devices. The established access key code is subsequently stored in the user communications device and made available to the service communications devices for use in subsequent communications sessions between the user communications device and any one of the service communications devices. The invention further relates to a communications system and a user communications device.
