Push-To-Talk Optimization
First Claim
1. A packet-based communication system comprising:
- a first network element that receives 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, said first compressed request message has a length of less than 30 bytes, and said first network element decompresses the first compressed request message to generate a first decompressed request message for transmission to a communication server;
said communication server supports a push-to-talk communication protocol and receives said first decompressed request message and processes said first decompressed request message to identify a group identifier for use in initiating a push-to-talk communication session, and said communication server generates a second decompressed request message based on said first decompressed request message for transmission to said first network element; and
said first network element receives said second decompressed request message from the communication server to transmit to a second network element that compresses the second decompressed request message to transmit to said terminating communication device 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 massages are used to initiate the push to talk communication session.

9. A method for communicating in a push-to-talk communication protocol on a packet-based communication system, comprising the steps of:
-
receiving at a first network element a first compressed request message for initiating a push-to-talk communication session, said first compressed request message having a length of less than 30 bytes; decompressing the first compressed request message to form a first decompressed request message; transmitting said first decompressed request message to a communication server; modifying said first decompressed request message at said communication server to form a second decompressed request message; transmitting said second decompressed request message to a second network element; compressing said second decompressed request message at the second network element to generate a second compressed request message having a length of less than 10 bytes; and transmitting said 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 (10, 11, 12, 13, 14)

15. A method for communicating on a packet-based communication system, comprising the steps of:
-
decompressing a first compressed request message at a first network element, said compressed request message originating at a mobile station to initiate a push-to-talk communication session; transmitting said first decompressed request message from the first network element to a communication server; preparing a second decompressed request message at the communication server 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 said second decompressed request message to generate a second compressed request message; and transmitting said second compressed request message to a terminating mobile station. - View Dependent Claims (16, 17, 18, 19, 20)
