3 Definitions and abbreviations p. 25
3.1 Definitions p. 25
For the purposes of the present document, the terms and definitions given in TR 21.905, ITU-T Recommendation E.164 [48] and the following apply:
Carrier textphone mode:
a mode for text communication, where continuous signals (i.e. a carrier tone) are present on the connection irrespective of whether text is being exchanged or not.
Carrierless textphone mode:
a mode for text communication, where signals are only present on the connection when text is being exchanged. E.g.: Baudot
SS7 signalling function:
function in the CS network, which has the capabilities to transport the SS7 MTP-User parts ISUP and BICC+STCmtp
SIP signalling function:
function in the IM CN subsystem, which has the capabilities to transport SIP
Incoming or Outgoing:
used in the present document to indicate the direction of a call (not signalling information) with respect to a reference point.
Incoming MGCF (I MGCF):
entity that terminates incoming SIP calls from the IMS side and originates outgoing calls towards the CS side using the BICC or ISUP protocols.
Outgoing Interworking Unit (O MGCF):
entity that terminates incoming BICC or ISUP calls from the CS side and originates outgoing calls towards the IMS using SIP.
Root Termination:
refers to Media Gateway as an entity in itself, rather than a Termination within it. A special TerminationID, "Root" is reserved for this purpose. See ITU-T Recommendation H.248.1. [2]
Signalling Transport Converter (STC):
function that converts the services provided by a particular Signalling Transport to the services required by the Generic Signalling Transport Service.
STCmtp:
Signalling Transport Converter on MTP. See ITU-T Recommendation Q.2150.1 [29].
BICC+STCmtp:
this terminology means that BICC signalling always needs to be used on top of STCmtp sublayer.
diverting URI:
the URI of the node by which the existing communication was last diverted/forwarded.
diverted-to URI:
the URI to which the existing communication is diverted/forwarded to.
ICE lite:
The lite implementation of the Interactive Connectivity Establishment (ICE) specified in RFC 8445.
Full ICE:
The full implementation of the Interactive Connectivity Establishment (ICE) specified in RFC 8445.
