Abstract:
When an emergency call is sent to a Public Safety Answering Point
(PSAP), the device that sends it, as well as any application service
provider in the path of the call, or access network provider through
which the call originated may have information about the call or the
caller which the PSAP may be able to use. This document describes
data structures and a mechanism to convey such data to the PSAP. The
mechanism uses a Uniform Resource Identifier (URI), which may point
to either an external resource or an object in the body of the SIP
message. The mechanism thus allows the data to be passed by
reference (when the URI points to an external resource) or by value
(when it points into the body of the message). This follows the
tradition of prior emergency services standardization work where data
can be conveyed by value within the call signaling (i.e., in body of
the SIP message) and also by reference.
