摘要:
A push-to-talk communication device including an operating answer mode indicates that operating answer mode to a Session Initiation Protocol/Internet Protocol based push-to-talk network server. The method includes employing as the operating answer mode of the push-to-talk communication device one of an automatic-answer mode, an always-automatic-answer mode and a manual-answer mode. A Session Initiation Protocol/Internet Protocol core network is employed including a Session Initiation Protocol/Internet Protocol push-to-talk network server. The operating answer mode is indicated in a Session Initiation Protocol message from the push-to-talk communication device to the Session Initiation Protocol/Internet Protocol push-to-talk network server over the Session Initiation Protocol/Internet Protocol core network.

The fire resistant material having a weight in the range of less than about 9.0 oz/yd2, an Arc Thermal Performance Value of greater than about 8.0 and a Thermal Protection Performance of greater than about 13.0.
摘要:
An apparatus and method for compressing and compressing text based messages. A TCCB layer 114, 115 is added to a mobile device 100 and P-CSCF 102. At the sending device, the TCCB compression method is invoked to remove all redundant header information contained in a message to be transmitted. When the TCCB compression method detects that a header's contents are the same as previously sent or received for a particular sequence, the TCCB method blanks the header contents. At the receiving device, when the TCCB layer receives a message with blank header contents, the TCCB decompression method is invoked to reconstruct the header from its cache 115, 127.
