41、ontrol 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. Once a conference is active, users can join and leave a conference, and remote users can be added to or
42、removed from the conference. Conference participants can request to be informed of these actions. The Management Object 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 Confere
43、nce Factory URI within the Management Object then the UE shall derive a Conference Factory URI for MMTEL as described in subclause 13.10 of 3GPP TS 23.003 15 to be used for the CONF service. ETSI ETSI TS 124 605 V15.0.0 (2018-06)83GPP TS 24.605 version 15.0.0 Release 15NOTE: Depending on the network
44、 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 derived Conference Factory URI might not be a valid URI. 4.3 Operational requirements 4.3.1 Provision/withdrawa
45、l 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. 4.3.3 Requirements in the network No specific requirements are needed in the network. 4.3.4 Requirements on t
46、he 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 Activation/deactivation The CONF service is activated at provisioning and deactivated at withdrawal. 4.5.1
47、a 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 subclause describes the usage of and the changes to the procedures of 3GPP TS 24.147 7 for invoking and opera
48、ting a conference. 4.5.2.1 Actions at the originating UE 4.5.2.1.1 User joining a conference Procedures according to 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
49、following additions to subclause 5.3.1.5.3 of 3GPP TS 24.147 7: - A UE that has initiated an emergency call, shall not 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 header ETSI ETSI TS 124 605 V15.0.0 (2018-06)93GPP TS 24.605 version 15.0.0 Release 15of the REFER request.
