Location Presence Event Package

Hello!

I would like to notify you about the the Internet Draft "A Location
Presence Event Package for the Session Initiation Protocol (SIP)".
http://www.ietf.org/internet-drafts/draft-pailer-locpres-00.txt

The draft describes the usage of the Session Initiation Protocol (SIP)
for subscriptions and notifications of location presence. Location
presence is information about the geographical position of a user.
Subscriptions and notifications of location presence are supported by
defining an event package within the general SIP event notification
framework.

The concept of a SIP based location enabler that is the core of the
proposed draft was published on several occasions:
*) A Terminal-Based Location Service Enabler for the IP Multimedia
Subsystem, R. Pailer, S. Bessler, F. Wegscheider, IEEE Wireless
Communications and Networking Conference April 2006 (WCNC06), Las Vegas,
USA
*) Terminal-Centric Location Services for the IP Multimedia Subsystem,
J. Fabini, M. Happenhofer, R. Pailer, IEEE 63rd Vehicular Technology
Conference, May 2006, Melbourne, Australia
*) Implementing a Native IMS Location Service Enabler over a
Prototypical IMS Core Network Testbed, P. Reichl, S. Bessler, J. Fabini,
R. Pailer, J. Zeiss,The Third IEEE International Workshop on Mobile
Commerce and Wireless Services (WMCS'06) June 26, 2006, San Francisco,
USA
*) Practical Experiences with an IMS-Aware Location Service Enabler on
Top of an Experimental Open Source IMS Core Implementation, P. Reichl,
S. Bessler, J. Fabini, R. Pailer, A. Poropatich, N. Jordan, R. Huber, H.
Weisgrab, C. Brandner, I. Gojmerac, M. Ries, F. Wegscheider, Journal of
Mobile Multimedia, Rinton Press, Fall 2006
*) Lecture Notes in Geoinformation and Cartography, Location Based
Services an TeleCartography, G. Gartner, W. Cartwright, M. P. Peterson
(Eds.), Springer, 2007

I can provide above documents in PDF format, if needed.

Feedback from the IETF Working Groups GEOPRIV and SIPPING would be
appreciated very much indeed.

greetings
Rudolf
