Achievements • Hard achievements • deliverables • Soft achievements • new members for ETSI • stimulated new work in TC SEC, TC STQ, ECMA TC 32, TC NA • recognition in IETF • cooperation with SG 16, T1, TIA, IMTC, MSAF, (MSF) • Spin offs: TTT-Net and TIPIA • The Validation Portfolio • TIPHON-Net • Interoperability event

6. Scope of WG7 The TIPHON wireless group shall work to ensure that the general VoIP architecture and protocols defined by TIPHON are well suitable or can be profiled towards use in wireless access IP networks. The scope of the TIPHON wireless group is to identify the requirements for current and future Wireless access networks to support TIPHON scenarios for IP Telephony services and to identify the specific technical requirements for TIPHON networks to interwork with current and future wireless access networks. Identified requirements will be liaised to the relevant standards bodies responsible for these wireless technologies. TIPHON will not specify any new wireless access technology/PLMN nor redefine existing wireless systems/PLMN or parts thereof. TIPHON can however initiate and stimulate standards work in this area by working on an architecture independent of any specific wireless access technology. Furthermore TIPHON will investigate aspects of mobility in the context of TIPHON scenarios. Mobility and wireless access are different concepts. Wireless access can exist without mobility (e.g. WLL); mobility can exist without wireless access, however the two can also coexist. Wireless and Mobility aspects

Statement of Direction Push globalisation byintensified cooperation with ANSI T1, TIA, IETF and SG 16addressing the Asian marketstart cooperation with TTC Strengthen our position in validation byintensified engagement in InterOpsbuilding TIPHON´s Implementers Net Evolution of work areas according to increased matureness Increase commitment of the operators

10. Audio and Video streaming Jitter can be a problem in live streaming Tele-medicine Prioritization is needed Conferencing and telephony (VoIP) “The killer application” Need for low latency and low data loss rates New Applications requiring QoS

11. The VoIP market as an alternative to the PSTN will grow with a compound annual growth rate (CAGR) of round about 104%...... ...on the condition that QoS is a standard Market trends

12. TIPHON and QoS • Develop further end-to-end approach • Use defined APIs for communication between application and network • Include QoS aspects in interoperability tests • Include wireless access aspects Close cooperation and worksplit with other organisationsis a prerequisite
