SunRocket^?

We do intend to implement necessary pieces for the deployment of an ECRIT solution and contribute back any software not specific to SunRocket^? as open source.

At present, I believe we will be implementing the following components:

• A LoST resolver.
• An L7-LCP server.
• Either SIP/PRES or HTTP dereference protocol (maybe both)
• Modification of our SIP proxies to support Location header.

Open Source HELD Client and LIS available at: http://sourceforge.net/project/showfiles.php?group_id=172377

Austrian Emergency Services Project

We have started a project in Austria we plan to fully demonstrate the following components by end of 2006:

• Georeferencing & HELD enabling a local BB ISP for their complete
• infrastructure
• Setting up a mock LoST service and mock PSAP's
• Working with client manufacturers (e.g. AVM Fritz!box) to enable
• Location conyeance in SIP and STUN+HELD lookups
• Optionally, deploying HELD client/DHCP location distribution in a
• Openwrt.org based access device, potentially with a SIP client or asterisk on same box
• Optionally, setting a business user scenario with switch-port based
• Location referencing and a local HELD server

We will base the HELD server on the Andrew prototype. We are interested in demonstrating both provider-asserted and user-provided location (e.g., by a SIRFIII GPS that should work indoor).

I'm actively seeking cooperation on co-development of a LoST server. It can be a prototype for now; with an eye towards production later. Let me know if you are interested. Results in open source only required.

Also, cooperation on showcase clients would be appreciated.

A possible client setup could be a Linksys router

• OpenWRT^? Linux
• Asterisk on openwrt
• Dumb terminal adapter on LAN / X-Lite on Laptop / WLAN
• Held client
• Asterisk modified to convey location as needed

A possible client platform would be a Nokia 770.
