Hi Mob group,

See the following High Level Progress report. Please inform group of any important aspect that I may have missed.

1. A conference call was held on 23 March 2000 with representatives from: AT&T, Alcatel, Ericsson, Intel, Lucent, Motorola, Nokia, Siemens.

2. The "All H.323 Scenario" was chosen to be studied and specified (out of the many other scenarios presented). When this work has been completed then the other scenarios will be specified. For the chosen scenario, mobility related contributions are now solicited for: Registration procedures, Gatekeeper discovery, Location update, Call establishment, Mid-Call scenarios (e.g. supplementary services, user interaction), Call release

Also it was decided to progress and add to the architectural work as required.

These contributions will enhance/form the base-line Annex H text for paragraphs 6, 7 and 8.

3. Next conference call is scheduled for 17 April, again at 8 a.m. PST.

4. It is now a matter of real concern that nothing much has moved in the Annex I (access and lower layer work). Any contributions to kick start this Annex would be appreciated.

5. For H.246 Annex E, it is important that the companies look at the MAP mapping for GSM and ANSI 41 contained in this annex.... to make sure that any errors are identified before the Osaka meeting.
