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 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: In a wireless communication system (100) having a plurality of communication cells (115, 117), and a plurality of mobile stations (118) operating within selected ones of the multiple communication cells (115, 117), a method and an apparatus for selecting those communication cells (115, 117). Within each communication cell (115, 117), a base station (112) transmits a message directed to the mobile stations (118), and detects a response indicator in the selected ones of the plurality of communication cells (115, 117). The response indicator may be an impulse radio-frequency energy transmission generated by the plurality of mobile stations (118) operating within the selected ones of the plurality of communication cells (115, 117). The base station (112) directs call traffic to the plurality of mobile stations (118) in the selected ones of the plurality of communication cells (115, 117).
