ABSTRACT:
The present invention provides a wireless telecommunications system comprising an interface mechanism for allocating a radio slot for a wireless link between a central terminal and a subscriber terminal within said wireless telecommunications system. At least one frequency channel is provided to support wireless links between the central terminal and the subscriber terminal, and a frequency channel is arranged to provide a plurality of radio slots. The interface mechanism comprises a radio manager, responsive to an indiction that a call is to be established, for issuing an allocation request message to a radio slave within the central terminal requesting that radio slave to allocate a radio slot for the call. Further, a radio slave, associated with a frequency channel, is provided to be responsive to receipt of the allocation request message from the radio manager, to reference a record identifying available radio slots within the frequency channel in order to select, if available, a radio slot within that frequency channel for allocation to the call, and to issue a response message to the radio manager indicating that a radio slot has been selected.
