Title:	LS to T2: SWG1 Liaison with External Bodies

Document for:	Approval 

___________________________________________________________________________
External Bodies to T2-SWG1
SWG1 have discussed the recent instruction from the Chairman of T2 that TSGs (and WGs) should not liaise with external bodies outside of the 3GPP and their supporting standards organisations without permission from the PCG. 

SWG1 would like to include the following list of organisations in the list of approved External Bodies, in addition to The  WAP Forum.

Sun Microsystems
For the development of APIs for MExE Release 99, SWG1 shall continue to liaise with API development groups approved by Sun Microsystems, such as the JavaPhone API group.

SWG1 would therefore like to recommend SUN Microsystems to the list of PCG approved external bodies. SWG1 would prefer to formally invite SUN to become an Individual Member Organisation of 3GPP.  This would expedite the process of standardisation if delegates from SUN or Javaphone were required to attend SWG1 at a later date. 

The GSM MoU
The following are technical bodies in the GSM MoU that SWG1 may wish to liaise with: -

•	SERG – Service Expert Rapporteur Group
•	SG – Security Group 

SWG1 note that The GSM MoU is already recognised as an “Organisational Partner” of 3GPP. 

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 SWG1, 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 SWG1 to continue to keep abreast of the W3C via the WAP Forum Ltd. However, 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.
