Summary:A SIP header field reduction protocol operating on a communication network is used for compressing the SIP header fields on SIP control messages used for initiating a SIP communication session. A new protocol is implemented on mobile user equipment (UE) (301) and a P-CSCF proxy SEP server (302). A prior SIGCOMP compression dictionary is used for compressing those header field parameters defined by the SIGCOMP dictionary. A new 3G dictionary is implemented with header field parameters for several wireless specific data elements and parameters necessary to access various wireless technologies and services which are missing from the SIP/SDP based SIGCOMP dictionary. Finally, an Encoding Assistant (EA) (310, 315) function is implemented on the UE and P-CSCF, which operates a standard encoding and decoding of SIP message header fields to reduce those SIP header fields that are dynamic over time but are essentially static in terms of most user communication. The EA parameters can be updated periodically, while the
