25、he ISDN CONF supplementary service. Within the Next Generation Network (NGN) the stage 3 is specified using the IP-Multimedia Call Control Protocol based on Session Initiation Protocol (SIP) and Session Description Protocol (SDP). The present document specifies centralized conferencing, using a conf

26、erence focus, distributed conferencing is out of scope. The present document does not cover the cases of: a) cascading conference services; and b) the support of the PSTN/ISDN conference service hosted in the PSTN. 2 References The following documents contain provisions which, through reference in t

40、l description When the CONF service is invoked, conference resources are allocated to the served user. Once a conference is active, users can join and leave a conference, and remote users can be added to or removed from the conference. Conference participants can request to be informed of these acti

41、ons. 4.3 Operational requirements 4.3.1 Provision/withdrawal The CONF service shall be provided after prior arrangement with the service provider. 4.3.1.1 Requirements on the originating network side No specific requirements are needed in the network. 4.3.1.2 Requirements in the network No specific

42、requirements are needed in the network. 4.3.1.3 Requirements on the terminating network side No specific requirements are needed in the network. 4.4 Coding requirements For coding requirements see TS 124 147 7, clause 5. 4.5 Signalling requirements 4.5.1 Activation/deactivation The CONF service is a

43、ctivated at provisioning and deactivated at withdrawal. 4.5.1A Registration/erasure The CONF service requires no registration. Erasure is not applicable.

44、 Invocation and operation This clause describes the usage of and the changes to the procedures of TS 124 147 7 for invoking and operating a conference. 4.5.2.1 Actions at the originating UE 4.5.2.1.1 User joining a conference Procedures according to TS 124 147 7, clause 5.3.1.4 shall apply. 4.5.2.1.

45、2 User inviting another user to a conference Procedures according to TS 124 147 7, clause 5.3.1.5 shall apply with the following additions to clause 5.3.1.5.3 of TS 124 147 7: In order to avoid the establishment of a second communication to the invited user, in case of an active session the UE may a

46、dditionally include the Replaces header in the header portion of the SIP URI of the Refer-to header of the REFER request. The included Replaces header shall refer to the active dialog that is replaced by the ad-hoc conference. The Replaces header shall comply with RFC 3891 8. NOTE: In case of an int

47、erworking to the PSTN the routing of the INVITE request from the conference focus to the MGCF that handles the Replaces information is not deterministic and the replacement of the active dialog might fail. EXAMPLE: Refer-To: 4.5.2.1.3 User leaving a conference Procedures according to TS 124 147 7, c

If not, the AS shall replace the Referred-By header with a valid value matching the REFER requests P-Asserted-Identity. If no Referred-By header is available in the request, the AS shall add a Refe
