Push-to-talk optimization
First Claim
1. A packet-based communication system, comprising a network infrastructure operable:
- to receive a first compressed request message from an originating communication device to initiate a push-to-talk communication session between the originating communication device and a terminating communication device; and
to decompress the first compressed request message to generate a first decompressed request message;
to process the first decompressed request message to identify a group identifier for use in initiating a push-to-talk communication session; and
to transmit to the terminating communication device a second compressed request message for initiation of the push-to-talk communication session.

Abstract
A push to talk message protocol operating on a communication network between an originating and terminating communication device operates to transmit compressed message formats to initiate the push to talk message protocol. Four compressed session protocol message formats are used in the preferred embodiment. A compressed originating session initiation invite message is transmitted from the originating mobile station. A compressed terminating session initiation invite message is received by the terminating mobile station. A compressed session initiation protocol ping message is transmitted from the originating mobile station and received by the terminating mobile station. A compressed 200 OK session initiation protocol message is transmitted from the terminating mobile station and received by the originating mobile station. Finally, the originating mobile decompresses the 200 OK session initiation protocol message. These compressed messages are used to initiate the push to talk communication session.

10. A method for communicating in a push-to-talk communication protocol on a packet-based communication system, comprising:
-
receiving at a network infrastructure a first compressed request message for initiating a push-to-talk communication session; decompressing the first compressed request message to form a first decompressed request message; modifying the first decompressed request message at said communication server to form a second decompressed request message; generating a second compressed request message; and transmitting the second compressed request message to a terminating mobile station to initiate a push-to-talk communication session with an originating mobile station. - View Dependent Claims (11, 12, 13, 14)

15. The method for communicating on a packet-based communication system, comprising:
-
decompressing a first compressed request message, the compressed request message originating at a mobile station to initiate a push-to-talk session; preparing a second decompressed request message based on said first request message with additional parameters that include a group identifier that identifies participants in the push-to-talk communication session; compressing the second decompressed request message to generate a second compressed request message; and transmitting the second compressed request message to a terminating mobile station. - View Dependent Claims (16, 17, 18, 19, 20)
