18、I ETSI TS 122 146 V13.0.0 (2016-02)43GPP TS 22.146 version 13.0.0 Release 13Foreword This Technical Specification has been produced by the 3rdGeneration Partnership Project (3GPP). The contents of the present document are subject to continuing work within the TSG and may change following formal TSG

19、approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval

20、; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introducti

21、on Broadcast and Multicast are methods for transmitting data-grams from a single 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 subscri

22、bers in a set of given cells over a shared broadcast channel. This service offers 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 suc

23、h does not offer any advantages as far as resource utilization within the PLMN 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

24、once on each link. For example, an SGSN will send data once to an RNC regardless 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 interf

25、ace with multiple transmissions of the same data. With increasing use of high bandwidth 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

26、are techniques to decrease the amount of data within the network and use resources more efficiently ETSI ETSI TS 122 146 V13.0.0 (2016-02)53GPP TS 22.146 version 13.0.0 Release 131 Scope This Technical specification defines the stage one description of the Broadcast and Multicast Services for the 3G

27、PP System. Stage one is the set of requirements which shall be supported for the 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

28、this specification. This TS includes information applicable to network operators, 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 doc

33、For the purposes of the present document, the definitions in 3GPP TR 21.905 1 as 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 th

34、e coverage area of the entire PLMN, or part(s) of the PLMNs coverage area. The 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 differ

35、ent content in different local broadcast areas. Broadcast mode: The part of MBMS that supports broadcast services. ETSI ETSI TS 122 146 V13.0.0 (2016-02)63GPP TS 22.146 version 13.0.0 Release 13Broadcast service: A unidirectional point-to-multipoint service in which data is efficiently transmitted f

36、rom a single source to multiple UEs in the associated broadcast service area. Broadcast 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-bounde

37、d reception of a broadcast service by the UE. A single broadcast service can only 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 bot

38、h to MS and User Equipment.) Multicast transmission activation: The process by 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

39、area may represent the coverage area of an entire PLMN, or part(s) of the PLMNs 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 ser

40、vice may have different content in different local multicast areas. Multicast mode: 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.

41、A single multicast service can only have one multicast session at any time. A multicast 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

42、to a group of users in a specific area. The MBMS has two modes: Broadcast mode 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 Mult

43、icast subscription group. Multicast subscription group members may join the corresponding 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. Mult

44、icast services can only be received by such users that are subscribed to the specific 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 ther

45、eby is authorised to join certain multicast services. Multicast subscription is 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 recei

46、ve multicast services associated with this group. User Equipment: defined in TS 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 Servi

48、tiple endpoints. These services are expected to be used extensively over wireless 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

49、 the home environment and other VASPs. The MBMS is a unidirectional point to multipoint 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
