Abstract:
In a radio communication system having a GSM (Global System for Mobile communications) cellular communication system that provides for both packet communications and circuit-switched communications, and that provides for a paging channel, the radio communication system having a mobile station and network infrastructure between which communications are effectuable by way of a radio link, the mobile station alternately operable in a packet communication mode and n circuit-switched communication mode, an improvement of apparatus far the network infrastructure for facilitating reassignment of the mobile station out of the packet communication mode and into the circuit-switched communication mode, said apparatus comprising:an allocator coupled to receive indications of communications to be effectuated with the mobile station necessitating operation of the mobile station in the circuit-switched communication mode, said allocator for allocating a time period during which the mobile station is to generate a page response message; and a page request message generator coupled to receive the indications of communications to be effectuated with the mobile station and indications of the time period allocated by said allocator, said page request message generator for generating a page request message for communication to the mobile station upon the paging channel, the page request message selectably including a multi-bit RRBP1 (Relative Reserve Block Period), field of digital value representative of the time period allocated by said allocator, the page request message for alerting the mobile station to commence reassignment thereof into the circuit-switched communication mode, the time period represented in terms of a frame reservation period.
