6.2.10A  IMS end-to-end Media Plane Security |R12|  p. 137

6.2.10A.1  End-to-end security for RTP based media using SDES  p. 137

This procedure is identical to that of clause 6.2.1 apart from the IMS-ALG providing "RTP/SAVP" or "RTP/SAVPF", as received in the SDP, to the IMS-AGW as transport protocol and not providing any other media related information to the corresponding terminations, and configuring the IMS-AGW to pass media transparently.
The IMS-ALG shall forward the SDP with unmodified transport protocol for those media lines and unmodified SDES SDP attribute(s).
Up

6.2.10A.2  End-to-end security for TCP-based media using TLS  p. 137

This procedure is identical to that of clause 6.2.1 apart from the IMS-ALG providing "TCP" to the IMS-AGW as transport protocol and not providing any TLS related information nor any other media related information to the corresponding terminations, and configuring the IMS-AGW to pass media transparently.
The IMS-ALG shall forward the SDP with unmodified transport protocol for those media lines and unmodified TLS related SDP attribute(s).
Up

6.2.11  Change Through-Connection  p. 137

The Change Through-Connection procedure is used for opening and closing of gates and is mandatory for IMS-ALG and IMS-AGW to support. The IMS-ALG sets the Stream mode parameter using the Change Through-Connection procedure to request the IMS-AGW to one-way or both-way through-connect or block media streams on a termination.
The IMS-ALG may combine the Change Through-Connection procedure with the Reserve and Configure AGW Connection Point, Reserve AGW Connection Point or Configure AGW Connection Point procedure as in Figure 6.2.1.2, or may apply this procedure separately.
Up

6.2.12  Emergency Calls  p. 137

This procedure is identical to that of clause 6.2.1 apart from the IMS-ALG requesting the IMS-AGW to treat the call as emergency call with a preferential handling by including the information element "Emergency Call Indicator" within the "Reserve and Configure AGW Connection Point" or "Reserve AGW Connection Point procedure".
