1. Standardization bodies

3G-324M standardization is complex

RADVISION is active in both standardization bodies and in all relevant working groups


2. WNSRP Allows negotiation of H.245 Control messages in

3. Behind The Scenes: The WNSRP Consortium


3. Behind The Scenes: Current Status

WNSRP was approved…

ITU

New H.324 version: August 2005

3GPP

New TR 26.911 version: September 2005

Vodafone’s video telephony spec (WNSRP is mandatory)


3. Behind The Scenes: 2006

A complementary solution to WNSRP is currently being debated

RADVISION is part of this discussion

At the time of writing, the complementary solution includes:

ACN RADVISION

FM

FSS

Interoperability1. Importance

2. RADVISION’S Approach


1. Importance

Reduces the risk of recalls

Mobile handsets recall is a costly process for both the operator and the handset vendor

Focus on both interoperability with handsets on the market as well as future extensions (introduction of new services and codec's)

Video is not as easy as Voice

More codec's

Capability negotiation is not a simple process

Implementing the exact codec profiles properly

Focus on quality in a 64Kbps bandwidth


3. RADVISION’S Approach

Commitment to the standardization process along with a high level of interoperability

Active member in all related international organizations

IMTC 3G-324M activity group co-chairman

Host of the next F2F event

RADVISION’S initiatives

WNSRP testing with operators and handset vendors

Remote IOT service on select features

2. Windows Mobile: Common Pitfalls

An integrated approach to Mobile Video Telephony

Forgetting to integrate with Call History

Dialing audio only or video calls won’t have the same call history

Not integrating fully with Direct Show and Phone Canvas

Inability to answer a call while listening to an MP3

Inability to switch properly between applications in the middle of a call


2. Windows Mobile: Interfaces
