39、4 CONFerence (CONF) 4.1 Introduction The CONFerence (CONF) service enables a user to participate in and control a simultaneous communication involving a number of users. 4.2 Description 4.2.1 General description When the CONF service is invoked, conference resources are allocated to the served user.

40、 Once a conference is active, users can join and leave a conference, and remote users can be added to or removed from the conference. ETSI ETSI TS 124 605 V13.0.0 (2016-01)83GPP TS 24.605 version 13.0.0 Release 13Conference participants can request to be informed of these actions. The Management Obj

41、ect as defined in 3GPP TS 24.166 14 provides a mechanism for the UE to discover the Conference Factory URI to be used for the CONF service. If the UE is not configured with the Conference Factory URI within the Management Object then the UE shall derive a Conference Factory URI for MMTEL as describe

42、d in subclause 13.10 of 3GPP TS 23.003 15 to be used for the CONF service. NOTE: Depending on the network operator, various mechanisms can be applied to discover the Conference Factory URI (e.g., include the Conference Factory URI in a letter written to the user or publish it on a website). A derive

43、d Conference Factory URI might not be a valid URI. 4.3 Operational requirements 4.3.1 Provision/withdrawal The CONF service shall be provided after prior arrangement with the service provider. 4.3.2 Requirements on the originating network side No specific requirements are needed in the network. 4.3.

44、3 Requirements in the network No specific requirements are needed in the network. 4.3.4 Requirements on the terminating network side No specific requirements are needed in the network. 4.4 Coding requirements For coding requirements see 3GPP TS 24.147 7, clause 5. 4.5 Signalling requirements 4.5.1 A

45、ctivation/deactivation The CONF service is activated at provisioning and deactivated at withdrawal. 4.5.1a Registration/erasure The CONF service requires no registration. Erasure is not applicable. 4.5.1b Interrogation Interrogation of CONF is not applicable. 4.5.2 Invocation and operation This subc

46、lause describes the usage of and the changes to the procedures of 3GPP TS 24.147 7 for invoking and operating a conference.

47、 3GPP TS 24.147 7, subclause 5.3.1.4 shall apply. 4.5.2.1.2 User inviting another user to a conference Procedures according to 3GPP TS 24.147 7, subclause 5.3.1.5 shall apply with the following additions to subclause 5.3.1.5.3 of 3GPP TS 24.147 7: - A UE that has initiated an emergency call, shall n

48、ot perform any procedures to add the remote user in that call to a conference. - In order to avoid the establishment of a second communication to the invited user, in case of an active session the UE may additionally include the Replaces header in the header portion of the SIP URI of the Refer-to he

49、ader 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 1: In case of an interworking 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: . NOTE 2: If a conference participant invites another user to a conference by using a REFER re
