Abstract: For steady state voice data packet transmission between a mobile station and a packet data service node a new compressed TCP/IP header (160) concatenated with a compressed RTP/UDP header (4) is sent. This concatenated header is seven bytes in length instead of the typical 40 byte long RTP/UDP/IP header. A new TCP header arrangement (30) transmits a special access code (161) to a Van Jacobson TCP/IP header compression/decompression arrangement (20). This allows the voice data packet to be transmitted to the receiving end without the other 33 bytes of header information. The PDSN regenerates the IP header and the receiving end then regenerates the RTP/UDP header (205) while it discards the new TCP header arrangement (30).

Abstract: A method and apparatus controls the display of information for troops and vehicles in a simulated battlefield. Rounds of munition are fired into the simulated battlefield and the effects of such munitions are displayed on the troops and vehicles display devices. These display devices include character displays for troops and display screen for vehicles. The text character display may include such information as damage assessment, weapon type, miss distance and miss direction. A screen display may be used for a vehicle display. The screen display depicts similar information as for the text character display, but in a graphical representation via icons representing various battlefield effects.
