Dear Q.F,G,K,2-5/16 experts,

As we need final approval of the SG16 management for the subject meeting, please register your contributions at an early occasion to Mr. Paul Jones paulej@packetizer.com even if the deadlines are set as follows:

/// Registration of the document: by 23:59 UTC, 30 April 2004 /// /// Distribution of the document: by 23:59 UTC, 4 May 2004 ///

Please be reminded that we need sufficient number of participants and contributions for the justification of holding Rapporteur meetings. Now I can expect sufficient number of participants in Beijing, the next is the number of contributions.

Please also note the following plea from Mr. Lehmann, Rapporteur for Q.K/16 (mobility). Please respond to him promptly, by the end of Monday 19 April at the latest, when he will decide if he can hold Q.K meeting in Beijing.

Dear experts,

We are planning to have a Rapporteur meeting in Beijing, China during the week of May 11-14, 2004.

With respect to Q.K (Mobility Management) I have collected very less essential contributions. So far I can only report about the discussions And meetings, which I had with 3GPP regarding the Liaison "mobility between H.323 muti media systems and GPRS/IMT2000 networks". I have not received any further contributions or interest from experts regarding any of the Q.K work tasks:

• Specification of mobility handling (terminal, user) between H.323

environments and GPRS/ IMT2000 networks

• Specification of service mobility with respect to roaming of user

profiles, mobile Multimedia collaboration applications and services

• Specification of Handover procedures where active sessions can be

maintained during location changes

• Specification of Interworking with NGN networks to support

generalised mobility handling

• Presence

or any further work task.

Due to this fact I would like to ask you urgently to send me some input until April 13, 2004. Q.K can only be successful if it receives contribution from various experts.

If I receive no further input until this date I have to consider to inform the SG16 management and the TSB that Q.K proposes to cancel the Q.K meeting in Beijing.

Best regards,
