A novel method and apparatus for transmitting voice traffic and data
traffic over a circuit-switched network and a packet-switched network are
presented. A new service option is introduced that allows a
circuit-switched network to strip off IP/UDP/RTP header information from
an internet protocol packet that may or may not be carrying multimedia
payloads. Selectively eliminating the reliability measures in the RLP
layer allows the circuit-switched network to reduce the delay associated
with data traffic, and thus satisfy the more stringent delay requirements
of voice traffic.
