Abstract

Various embodiments are described to address the need for providing substantially reduced PTT call setup times and more efficient wireless bandwidth utilization for PTT sessions utilizing an IP-based protocol. The use of non-IP messaging between an originating MS (101) and PCF (131) and a target MS (102) and PCF (132), the use of IP-based messaging between the PCFs, the use of access channel signaling by the originating MS, and the generation of SIP responses by a target PCF on behalf of the target MS are described. Embodiments incorporating some or all of these protocol changes, can provide either, or both, reduced end-to-end call setup time for PTT as it presently exists in IS-2000 systems or reduced bandwidth consumption.

Claims

AMENDED CLAIMS [(received by the International Bureau on 20 October 2005 (20.10.05); new claims 18 to 21 added; remaining claims unchanged (2 pages)]
18. A mobile station (MS) for facilitating a push-to-talk (PTT) session initiation using an Internet Protocol (IP)-based protocol, the MS comprising: means for detecting a session initiation indication; means for sending, in a non-IP format, a session initiation request for the PTT session, to a base station (BS) via a CDMA access channel; means for sending to the BS a channel assignment request for the PTT session via a CDMA access channel; and means for receiving messaging in response to the session initiation request.
19. A packet control function (PCF) for facilitating a push-to-talk (PTT) session initiation using an Internet Protocol (IP)-based protocol, the PCF comprising: means for maintaining session information relating to a dormant IP data session of an originator unit; means for receiving, from the originator unit via a base station (BS), a session initiation request in a non-IP format for the PTT session; means for generating an IP-based message using the session information and the session initiation request in a non-IP format; and means for sending the IP-based message to a PTT server.
20. A packet control function (PCF) for facilitating a push-to-talk (PTT) session initiation using an Internet Protocol (IP)-based protocol, the PCF comprising: means for maintaining session information relating to a dormant IP data session of a target unit; means for receiving, from a PTT server, session initiation request messaging for the target unit for the PTT session; means for requesting, in response to the session initiation request messaging, that the target unit be paged; means for receiving, from a base station (BS), an indication that the target unit responded to a page; means for generating, in response to the indication that the target unit responded to the page, response messaging using information from the session information and the session initiation request messaging; and means for sending the response messaging to the PTT server.
21. A packet control function (PCF) for facilitating a push-to-talk (PTT) session initiation using an Internet Protocol (IP)-based protocol, the PCF comprising: means for maintaining session information relating to a dormant IP data session of a target unit; means for receiving, from a PTT server, session initiation request messaging for the target unit for the PTT session; means for requesting, in response to the session initiation request messaging, that the target unit be paged; means for receiving an indication that the target unit is unavailable; means for generating, responsive to the indication that the target unit is not available, target-not-available messaging using information from the session information and the session initiation request messaging; and means for sending the target-πot-available messaging to the PTT server.
