1. 1 QUALCOMM Corporate R & D VoIP Supplementary Service Status July 23 rd, 2007

2. 2 QUALCOMM Corporate R & D Stage 1 Status S.P0125-0 v0.3 under development in TSG-S WG1 –Vanity Number was removed from the supplementary service list –Baseline text for all other services are in place –Fine-tuning service interaction requirements to ensure consistency –Expected to start review out of Calgary meeting

3. 3 QUALCOMM Corporate R & D Stage 2/3 Status Stage 2&3 are under developing in TSG-X MMD group Stage 2 call flows are converging –A number of open issues resolved in June meeting: Call transfer, 3WC, Flexible Alerting –Main open issues include Customized Ring Back Tone and service identification for empty initial INVITE Stage 3 –Start adding procedures for services not common with TISPAN/3GPP –For 3GPP/TISPAN common services »Received permission from TISPAN to reproduce Release 1 documents »Working on permission for 3GPP R7 documents

4. 4 QUALCOMM Corporate R & D Next Steps Make Stage 1 ready for review Resolve stage 2 open issues Start adding procedures for 3GPP/TISPAN common services with proper references –Use TISPAN as main reference Contribute back to 3GPP/TISPAN common IMS work –Take 3GPP2 modifications (e.g., REFER interworking etc) into 3GPP/TISPAN
