              Namespace for Local Emergency Communications
               draft-polk-local-emergency-rph-namespace-01

Abstract

   This document creates the new Session Initiation Protocol (SIP) 
   Resource Priority header field namespace "esnet" for local emergency
   usage to a public safety answering point (PSAP), between PSAPs, and 
   between a PSAP and first responders and their organizations, and 
   places this namespace in the IANA registry.

1.  Introduction

   This document creates the new Session Initiation Protocol (SIP) 
   Resource Priority header field namespace "esnet" for local emergency
   usage and places this namespace in the IANA registry.  The SIP 
   Resource-Priority header field is defined in RFC 4412 [RFC4412]. 
   This new namespace can be used for inbound calls towards a public 
   safety answering point (PSAP), between PSAPs, and between a PSAP and
   first responders or their organizations.  

   This new namespace can be included in SIP requests to provide an 
   explicit priority indication within controlled environments, such as
   an IMS infrastructure or Emergency Services network (ESInet) where 
   misuse can be reduced to a minimum because these types of networks 
   have great controls in place.  The function is to facilitate 
   differing treatment of emergency SIP requests according to local 
   policy, or more likely, a contractual agreement between the network 
   organizations.  This indication is used solely to differentiate
