ABSTRACT:
An access technology integrated header compression method or apparatus sends an IP-based speech data packet over a radio interface without sending information related to changes in the IP identification, RTP sequence number, or RTP time stamp. The omission of information related to changes in these fields from the header reduces the bandwidth consumed by the header. These fields are then reconstructed at the receiver side of the radio interface.
