7.5.2.2 Reference point MCPTT-1 (between the MCPTT client and the MCPTT server)
The MCPTT-1 reference point, which exists between the MCPTT client and the MCPTT server, is used for MCPTT application signalling for establishing a session in support of MCPTT. The MCPTT-1 reference point shall use the SIP-1 and SIP-2 reference points for transport and routing of SIP signalling. The MCPTT-1 reference point may use the HTTP-1 and HTTP-2 reference points. The TMGI is communicated between the MCPTT server and the MCPTT client using the MCPTT-1 reference point. Information that is reported to the MCPTT server from the MCPTT client shall be configurable at the application layer. This interface may include the area where a UE is currently located, described as ECGI of the serving and neighbouring cell(s), MBMS SAIs, MBSFN Area ID. This information comes from the broadcast by the local cell, e.g. from SIB1 and SIB15 (see 3GPP TS 36.331 [12]) as decoded by the UE. NOTE: This reference point includes the GC1 reference point as described in 3GPP TS 23.468 [9]. It is assumed that the MCPTT server is performing the function of GCS AS. While 3GPP TS 23.468 [9] does not specify GC1 it does include high level descriptions of certain interactions on GC1, including those relating to the availability of multicast delivery for the application client. The MCPTT-1 reference point fulfils the requirements of the GC1 reference point for MCPTT. Messages supported on this interface may also include the MCPTT server providing the MCPTT client with information describing the mapping of transport resources to specific group calls.

The MCPTT-3 reference point exists between the MCPTT server and the MCPTT server and between the MCPTT server and the MC gateway server for MCPTT application signalling for establishing MCPTT sessions. The MCPTT-3 reference point shall use the SIP-2 reference point for transport and routing of signalling. If a pair of MCPTT servers, or an MCPTT server and an MC gateway server, are served by different SIP cores then the MCPTT-3 reference point shall also use the SIP-3 reference point for transport and routing of signalling. Floor control signalling and media are also transferred using the MCPTT-3 reference point.

The MCPTT-5 reference point, which exists between the MCPTT server and the EPS, is used, subject to the conditions below, by the MCPTT server to obtain unicast bearers with appropriate QoS from the EPS. It utilises the Rx interface of the EPS according to 3GPP TS 23.203 [4]. MCPTT-5 is not used when the MCPTT service provider and the PLMN operator do not have an operational agreement for QoS control to be provided directly from the MCPTT service provider domain. MCPTT-5 may be used when the MCPTT service provider and the PLMN operator have an operational agreement where QoS control is provided directly from the MCPTT service provider domain. NOTE: Any coordination between the P-CSCF use of Rx and the MCPTT server use of Rx (via MCPTT-5) from the MCPTT service provider domain is not specified in this release of this specification.

10.4.3 Authorized user remotely changes another MCPTT user's selected MCPTT group – mandatory mode
Procedure for an authorized user to change other MCPTT users' selected MCPTT group without requiring target user's approval is described in figure 10.4.3-1. Pre-conditions: - The MCPTT client 1 has already been provisioned (statically or dynamically) with the target MCPTT user's information and its group information, that the selected MCPTT group of target MCPTT user 2 is allowed to be changed; Figure 10.4.3-1: Remotely change MCPTT group selection – mandatory mode 1. When an authorized user changes other MCPTT users' selected MCPTT group, the MCPTT client 1 sends MCPTT group selection change request to the MCPTT server. The information (i.e. target MCPTT ID, MCPTT group ID) used to set the requested MCPTT group as the selected MCPTT group of the target MCPTT user shall be included. 2. The MCPTT server shall check if the MCPTT user 1 is authorized to change the target MCPTT user's selected MCPTT group. The MCPTT server shall perform the affiliation relationship check based on the stored affiliation status. 3. If the MCPTT user 1 is authorized to change the target MCPTT user's selected MCPTT group, and if the target MCPTT user is not already affiliated to the requested MCPTT group, the remotely change of affiliation procedures shall be performed (see subclause 10.8 in 3GPP TS 23.280 [16]). 4. The MCPTT server then shall send the MCPTT group selection change notification including the target user ID and the selected MCPTT group ID to the MCPTT client 2. 5. The group selection change response then returns to the MCPTT client 1. 6. Target MCPTT client 2 are notified about the change of its selected MCPTT group.

85bf19f2724bd70687927dc10941722c
23.379
10.5.1 General
The MCPTT server and client may use one or more pre-established sessions as defined in 3GPP TS 23.280 [16] for the following procedures for on-network: - Group calls (as specified in subclause 10.6.2.3 and subclause 10.6.2.4); - Private calls (as specified in subclause 10.7.2.2 and subclause 10.7.2.3); - MCPTT emergency group calls (as specified in subclause 10.6.2.6.1); - MCPTT imminent peril group calls (as specified in subclause 10.6.2.6.2); - MCPTT emergency private calls (as specified in subclause 10.7.2.4); and - MCPTT emergency alerts (as specified in subclause 10.6.2.6.3). For outgoing MCPTT call setup for a private call or a pre-arranged group call using a pre-established session, an MCPTT UE uses SIP procedures to establish the call. For incoming MCPTT call setup for a pre-arranged group call using a pre-established session, media plane control procedures are used to establish the call between the MCPTT server and client. For incoming MCPTT call setup for a private call using a pre-established session, SIP procedures are used to establish the call between the MCPTT client and server in manual commencement mode and media plane control procedures in automatic commencement mode. An MCPTT UE can join an MCPTT chat group using a pre-established session by sending a group join request using SIP procedures. NOTE: A chat group call is started and notified using floor control messages regardless of whether pre-established session is used.

MCPTT server has determined to include MCPTT client A in the call e.g., upon receiving the request from another MCPTT client to include MCPTT client A in the call. 3. Pre-established session call connect request information flow is sent by the MCPTT server to inform MCPTT client A using a pre-established session that it has been connected to MCPTT private or group call. The floor control is established between floor participant A and floor control server.
