Abstract:
In 3rd-Generation Partnership Project (3GPP) networks, the signalling
path between a calling user and a called user can be partioned into
segments, referred to as traffic legs. Each traffic leg may span
networks belonging to different operators, and will have its own
characteristics that can be different from other traffic legs in the
same call. The directionality in traffic legs relates to a SIP
request creating a dialogue and stand-alone SIP request. A traffic
leg might be associated with multiple SIP dialogs, e.g. in case a
B2BUA which modifies the SIP dialog identifier is located within the
traffic leg.
This document defines a new SIP URI parameter, 'iotl'. The parameter
can be used in a SIP URI to indicate that the entity associated with
the address, or an entity responsible for the host part of the
address, represents the end of a specific traffic leg (or multiple
traffic legs).
The SIP URI 'iotl' parameter defined in this document is only
applicable to 3GPP networks. The usage of the parameter within other
types of networks is undefined.
