Title:	SWG1 Liaison with External Bodies

Document for:	Discussion

___________________________________________________________________________

Introduction
The 3GPP PCG has recently instructed that TSGs (and WGs) should not liaise with external bodies outside of the 3GPP and the supporting standards organisations without permission from the PCG. This includes external bodies like The WAP Forum Ltd and Sun Microsystems who have so far, been the main external bodies liaised with by ETSI in the case of MExE.

It has already been agreed to allow ETSI to transfer the MExE work into 3GPP and for TSG-T to support the development of MExE in 3GPP. T-SWG1 clearly needs to continue to liaise with the above two organisations and this paper identifies several other external bodies that should be recommended to the PCG for inclusion in the list of approved external bodies.

External Bodies to T SWG-1
The GSM MoU
T-SWG1 should regularly liaise with the GSM MoU to ensure that GSM operators are kept abreast of future service implementation requirements related to the terminal execution environment.  The following are technical bodies in the GSM MoU which T-SWG1 may wish to liaise with.
•	SERG – Service Expert Rapporteur Group
•	SG – Security Group 

Internet Engineering Task Force (IETF)
It is envisaged that 3GPP will have to liaise with the IETF on matters relating to the core network architecture, e.g. Mobile IP. TSG-T, in particular SWG-1, has reason to liaise with the IETF on the following areas: -
•	HTTP Client-Server negotiation.
•	Security 

The VXML (Voice eXtensible Mark-Up Language) Forum
This is an organisation established to develop an open, platform-independent set of specifications for a mark-up language that allows Internet content and applications to be written in a format that can be accessed via traditional voice interfaces, i.e. using a mobile handset.

VXML is supported by around 20 companies and will be ready for public comment in April 1999. The final version of the initial specification will be submitted to W3C for standardisation later this year.

For more information see http://www.vxmlforum.org/    

World Wide Web Consortium (W3C)
The overlap of work being done in the WAP Forum Ltd and W3C has led to greater collaboration between the two organisations in their work towards a unified information space. 

This joint effort may make it sufficient for T-SWG1 to continue to keep abreast of the W3C via the WAP Forum Ltd. However, T-SWG1 may need to liaise directly with W3C on issues that are generic to all classes of future MExE devices. For example, how the evolution of HTML might impact the way in which devices specify their capabilities and how they must send this information to the server.

Summary
The organisations described above will provide a good starting point of external bodies that SWG-1 should recommend to the PCG in addition to The WAP Forum Ltd and Sun Microsystems. 

SWG-1 must be able to add organisations to this list as the needs of the MExE work item dictates. However, it is recommended that SWG-1 should as far as possible agree a list of external bodies to the PCG as early as possible in order to avoid delays to the specifications.
