Abstract: A communications system for providing packet data service to mobile stations (110) performs registration of the mobile station prior to engaging in packet data service. The registration procedure includes sending a request to register (300) to a DAP (113), transferring (302) subscriber data from an HLR (124) to a D-VLR (126), authenticating (30 6) the mobile subscriber, selecting a mobile data gateway (116) to service the mobile station, transferring (308) the subscriber data from the D-VLR to the mobile data gatewa, and establishing (312) a packet data link between the mobile data gateway and the mobile station.

Abstract: A communications system (100) has a TDMA signal (110) accessed by one or more mobile stations (104). The TDMA signal carries both circuit switched and packet data service. A packet channel is defined within a packet data frame (208) by assigning time slots not used by other services during the packet data frame to the packet channel. A packet data seed channel (204) is used to anchor the packet channel and steer a mobile station to the packet channel. In the packet data seed channel a dynamic allocation protocol (DCAP) slot (206) appears and carries the packet channel slot assignments for the next occurring packet data frame.

Abstract: A radio communication system controller embodies the present invention by providing extended use (306) of a communication resource (106) to a plurality of communication units. The inventive method includes the steps of assigning (402) a first communication resource to a first communication unit, and then temporarily configuring (406) the assigned communication resource as a reserved resource. The controller then receives (408), from a second communication unit, a request to transmit a second communication on the assigned communication resource. Lastly, the controller re-configures (412) the assigned communication resource to allow transmission of the second communication on the assigned communication resource.

Abstract: A quality dispatch service on a CDMA based wireless system (50). To achieve spectral efficiency and fast access for follow-up calls, in response to a request by a talkgroup member (A-D) to have a group call established, the non-requesting (listening-only) members (B-D) are allowed to establish a low-rate (non-voice) signaling link (54-56) in the reverse direction (inbound) for the limited purpose of (i) providing forward power control information to the fixed infrastructure; (ii) requesting soft hand-off when required; and (iii) maintaining the correct reverse link power control to allow for fast channel access for a follow-on call.

Abstract: A wireless communication unit ( 120 ) polls ( 200 ) a radio access point ( 110 ) at a certain frequency. The wireless communication unit ( 120 ) then determines ( 210 ) whether packets are received in response to the polling and determines ( 220 ) the percentage of polls resulting in receipt of packets. The wireless communication unit ( 120 ) then adjusts ( 230 ) the polling frequency to change the number of polls which result in the receipt of packets. Optionally, the wireless communication unit ( 120 ) repolls ( 240 ) the radio access point ( 110 ) when a packet in not received. Then, the wireless communication unit ( 120 ) plays ( 250 ) the packet at a certain time. Alternatively, the wireless communication unit ( 120 ) receives ( 310 ) packets without polling and determines ( 220 ) a radion access point frequency at which packets arrive at the radio access point ( 110 ). The polling frequency is then set ( 330 ) to approximately the radio access point frequency.
