Abstract:
In telecommunication 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', which 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 'iotl' parameter is defined in order to fulfil requirements from
the 3rd-Generation Partnership Project (3GPP), but it can also be
used in other network environments.
