The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will b

Introduction Broadcast and Multicast are methods for transmitting data-grams from a singl
21、e source to several destinations (point-to-multipoint). To date, release-4 and release-99 define two services in this respect: A cell broadcast service (CBS) allowing for low bit-rate data to be transmitted to all subscribers in a set of given cells over a shared broadcast channel. This service offe
22、rs a message-based service 5,6 An IP-Multicast service allowing for mobile subscribers to receive multicast traffic. This service does not allow for multiple subscribers to share radio or core network resources and as such does not offer any advantages as far as resource utilization within the PLMN
23、and over the radio access network. 3,4 It is envisaged that for some applications, multiple users can receive the same data at the same time. The benefit of multicast and broadcast in the network is that the data is sent once on each link. For example, an SGSN will send data once to an RNC regardles
24、s of the number of Node Bs and UEs that wish to receive it. The benefit of multicast and broadcast on the air interface is that many users can receive the same data on a common channel, thus not clogging up the air interface with multiple transmissions of the same data. With increasing use of high b
25、andwidth applications in third generation mobile systems, especially with a large number of users receiving the same high data rate services, efficient information distribution is essential. Thus, broadcast and multicast are techniques to decrease the amount of data within the network and use resour
26、ces more efficiently ETSI ETSI TS 122 146 V14.0.0 (2017-03)53GPP TS 22.146 version 14.0.0 Release 141 Scope This Technical specification defines the stage one description of the Broadcast and Multicast Services for the 3GPP System. Stage one is the set of requirements which shall be supported for th
27、e provision of Broadcast and Multicast services, seen primarily from the subscribers and service providers points of view. Note: Non-3GPP access systems may provide MBMS transport service, but this is not in the scope of this specification. This TS includes information applicable to network operator
28、s, content providers, and terminal and network manufacturers. This TS contains the core requirements for Multicast and Broadcast Services, which are sufficient to provide a complete service. 2 References The following documents contain provisions which, through reference in this text, constitute pro

33、s well as the following definitions apply. Broadcast service area: The area in which a specific broadcast service is available. It is defined individually per broadcast service. The broadcast service area may represent the coverage area of the entire PLMN, or part(s) of the PLMNs coverage area. The
34、broadcast service area is the sum of all local broadcast areas offering the same service. Local Broadcast Area: The area of a broadcast service, where the service content is the same. One broadcast service may have different content in different local broadcast areas. ETSI ETSI TS 122 146 V14.0.0 (2
35、017-03)63GPP TS 22.146 version 14.0.0 Release 14Broadcast mode: The part of MBMS that supports broadcast services. Broadcast service: A unidirectional point-to-multipoint service in which data is efficiently transmitted from a single source to multiple UEs in the associated broadcast service area. B
36、roadcast services may be received by all users who have enabled the specific broadcast service locally on their UE and who are in the broadcast area defined for the service. Broadcast session: A continuous and time-bounded reception of a broadcast service by the UE. A single broadcast service can on
37、ly have one broadcast session at any time. A broadcast service may consist of multiple successive broadcast sessions. Mobile Station (MS): Defined in 3GPP TS 24.002. (The abbreviation “UE“ in this specification refers both to MS and User Equipment.) Multicast transmission activation: The process by
38、which the network activates the transmission of Multicast data. Multicast service area: The area in which a specific multicast service is available. It is defined individually per multicast service. The multicast service area may represent the coverage area of an entire PLMN, or part(s) of the PLMNs
39、 coverage area. The multicast service area is the sum of all local multicast areas offering the same service. Local multicast area: The area of a multicast service, where the service content is the same. One multicast service may have different content in different local multicast areas. Multicast m
40、ode: The part of MBMS that supports multicast services. Multicast joining: The process by which a user joins a multicast group. Multicast session: A continuous and time-bounded reception of a multicast service by the UE. A single multicast service can only have one multicast session at any time. A m
41、ulticast service may consist of multiple successive multicast sessions. Multimedia Broadcast/Multicast Service (MBMS): A unidirectional point-to-multipoint service in which data is transmitted from a single source entity to a group of users in a specific area. The MBMS has two modes: Broadcast mode
42、and Multicast mode. Multicast group: A group of users that have an activated MBMS in multicast mode and therefore are ready to or are receiving data transmitted by this service. The multicast group is a subset of the Multicast subscription group. Multicast subscription group members may join the cor
43、responding multicast group. Multicast service: A unidirectional point-to-multipoint service in which data is efficiently transmitted from a single source to a multicast group in the associated multicast service area. Multicast services can only be received by such users that are subscribed to the sp
44、ecific multicast service and have joined the multicast group associated with the specific service. Multicast subscription: The process by which a user subscribes or is subscribed to a multicast subscription group and thereby is authorised to join certain multicast services. Multicast subscription is
45、 performed either upon user selection or due to home environment initiation. Multicast Subscription Group: A group of users who are subscribed to a certain MBMS in multicast mode and therefore authorised to join and receive multicast services associated with this group. User Equipment: defined in TS
46、 21.905. An occurrence of a User Equipment is an MS for GSM as defined in TS 24.002. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: MBMS Multimedia Broadcast/Multicast Service MS Mobile Station UE User EquipmentETSI ETSI TS 122 146 V14.0.0 (2017-03)73G
47、PP TS 22.146 version 14.0.0 Release 144 General description of a multimedia broadcast/multicast service (MBMS) Point to multipoint services exist today which allow data from a single source entity to be transmitted to multiple endpoints. These services are expected to be used extensively over wirele
48、ss networks, hence there is a need for a capability in the PLMN to efficiently support them. The Multimedia Broadcast/Multicast Service (MBMS) will provide this capability for such broadcast/multicast services provided by the home environment and other VASPs. The MBMS is a unidirectional point to mu
49、ltipoint bearer service in which data is transmitted from a single source entity to multiple recipients. It is anticipated that other services will use these bearer capabilities. MBMS also enables an IMS application located on an application server to send multimedia to a set of IMS users in the service area by means of MBMS bearer service. 3GPP has defined two modes of operation: - the broadcast mode - the multicast mode. 4.1 MBMS broadcast mode The broadcast mode is a unidirectional point-to-multipoint transmission of multimedia data (e.g. te
