S Wireless and Mobility aspects

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.

S 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

S New Applications requiring QoS

• Audio and Video streamingJitter 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

S Market trends

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

Close cooperation and worksplit with other organisationsis a prerequisite

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
