Abstract
In a wireless communication system, a wireless communication device transfers a SIP INVITE message having a first header with a first value indicating a location-handling requirement. The SIP INVITE message also has a second header with a location value. A communication signaling processing system processes the SIP INVITE message to determine a second value responsive to the first value indicating the location-handling requirement. The processing system replaces the location value in the second header of the SIP INVITE message with the second value. The processing system transfers the SIP INVITE message with the second value in the second header.
