A term defined in the present document takes precedence over the definition of the same term, if any, in 3GPP TR 21.905 1. Content Provider: Entity/Entities whic
35、h supplies/supply content in the form of streaming media or non-real-time (NRT) files to be delivered to UEs over the 3GPP network, via MBMS Bearer and/or unicast bearer services. Also referred to in this document as the Multicast Broadcast Source. The Content Provider may reside either inside or ou
36、tside the operators network. Service: One of the resource types exposed by the RESTful xMB API and operated on by a Content Provider using HTTP methods. It corresponds to a Content Providers service offering for delivery over the MBMS network to UEs. Each service instance created over the xMB API ma
37、ps to an MBMS User Service as specified by 3GPP TS 26.346 3. The delivery of the contents of a created service is performed during one or more sessions associated with that service. Session: One of the resource types exposed by the RESTful xMB API and operated on by a Content Provider using HTTP met
38、hods. It represents one or more time intervals during which the MBMS Bearer is active for the transmission of service contents from the BM-SC to the UE. Each session instance, besides the activity times, may contain various properties pertaining to transport, media and application level information
39、(session type, session state, data rate, permitted delay, user plane ingestion mode, targeted delivery area, reporting parameters, identification of content components delivered during the session, etc.). 3.2 Abbreviations For the purposes of the present document, the abbreviations given in 3GPP TR

Control- and user-plane procedures are operated ov
44、er the xMB-C and xMB-U reference points, respectively. The overall xMB reference model is depicted in subclause 5.4A of 3GPP TS 26.346 3. Figure 4.2.1 xMB reference point For the V2X Localized User Plane supported feature, the reference model in Annex B.3 of 3GPP TS 23.285 23 applies. 4.3 Functional
45、 elements 4.3.1 BM-SC The complete functionality of the BM-SC is defined in 3GPP TS 26.346 3. In the context of the xMB reference point, the BM-SC represents the peer endpoint to the Content Provider in supporting all procedures on the xMB interface. In addition to the functions defined in 3GPP TS 2
46、6.346 3, the BM-SC may support, for V2X services, the V2X Localized User Plane procedures as defined in 3GPP TS 23.285 23 subclause 5.4.2.2 for receiving Local MBMS information from the Content Provider acting as a V2X Application Server. 4.3.2 Content Provider / Multicast Broadcast Source The funct
47、ional role of the Content Provider is defined in subclause 4.4.1a of 3GPP TS 26.346 3. Using the xMB reference point, a Content Provider/Multicast Broadcast Source may provide media, as well as service descriptions and control data, to the BM-SC to set up and manage MBMS User Service(s) from the BM-
48、SC to MBMS clients (the latter is not depicted in Figure 4.2.1). In addition, the Content Provider which acts as a V2X Application Server may support V2X Localized User Plane procedures as defined in 3GPP TS 23.285 23 subclause 5.4.2.2 for requesting the BM-SC to activate an MBMS bearer for Local MB
