ESTABLISHING A WIRELESS LINK BETWEEN A CENTRAL TERMINAL AND A SUBSCRIBER TERMINAL OF A WIRELESS TELECOMMUNICATIONS SYSTEM

摘要

The present invention provides a wireless telecommunications system comprising an interface mechanism for establishing a wireless link between a central terminal and a subscriber terminal within said wireless telecommunications system. The interface mechanism comprises a radio port manager within the central terminal for configuring the central terminal to receive an acquisition request message from a subscriber terminal on a radio slot associated with the radio port manager, and a radio port slave within the subscriber terminal for receiving an invitation message inviting the subscriber terminal to acquire the wireless link on said radio slot, and for issuing the acquisition request message to said radio port manager. The radio port manager is responsive to receiving the acquisition request message to grant the subscriber terminal access to the radio slot. It has been found that this technique provides a particularly efficient way of managing the establishment of wireless links between a central terminal and a subscriber terminal of a wireless telecommunications system, in situations where the radio slot used for the wireless link may vary from call to call.
