Introduction
TS 22.146 [2] specifies the multimedia broadcast and multicast service (MBMS) application independent transport
service and includes some guidance on application services and bit rates. The present specification defines MBMS
User Services that use the capabilities of MBMS. Service related information is defined in this specification to specify
requirements in terms of data rates, quality of service requirements, typical volumes of data etc.
MBMS User Services may be delivered to a user at different bit rates and quality of service depending on radio
networks and conditions. This technical specification describes service scenarios for MBMS User Services.
In addition scenarios related to security and charging are described providing information for detailed MBMS User
Services security and charging mechanisms to be specified. The service scenarios described in this specification are not
exhaustive, it is possible that MBMS may be used for services that are not included in this specification. The present
specification describes the minimal requirements for interoperability for MBMS based services. This specification
establishes a basis which can also be used for future services.

4 Classification of MBMS User Services
There exist many services and applications that can be provided over the application independent MBMS transport [2].
It is not necessary to standardise specific end user services because the deployment of particular applications and
services over the capabilities provided by the 3GPP system is operator specific and outside the scope of standardisation.
However, it is possible to classify MBMS User Services according to the method used to distribute these services.
There are four types of MBMS User Service considered within this specification.
• Streaming services
A continuous data flow providing a stream of continuous media (i.e. audio and video) is a basic MBMS User
Service. Like digital video broadcasting, supplementary information of text and/or still images (static media) is
also important. For example, if text includes URLs of some content on the Internet, a user can easily access the
content without entering the URL for herself. Still images may also be used for banner images that advertise
some product or service. These static media need to be synchronized and displayed with audio/video streams.
Note: Streaming in the context of MBMS User Services may not be the same as that described e.g. within PSS
[4].
• File download services
This service delivers binary data (file data) over an MBMS bearer. An MBMS client (i.e. UE) activates an
appropriate application, and utilises the delivered data. The most important functionality for this service is
reliability. In other words, it is necessary that the user receive all the data sent in order to experience the service.
• Carousel services
Carousel is a service that combines aspects of both the Streaming and File download services described above.
Similar to the streaming service this service includes time synchronisation. However, the target media of this
ETSI
---------------------- Page: 7 ----------------------
3GPP TS 22.246 version 15.0.0 Release 15 7 ETSI TS 122 246 V15.0.0 (2018-07)
service is only static media (e.g. text and/or still images). Time synchronization with other media is also
required. For example, text objects are delivered and updated from time to time. Still images may also be
collated to display low frame-rate video. In common with the download service this service also includes
reliability (typically 100% reliability is not always necessary). The benefit of this service is that it is possible
over a low bit-rate bearer.
An example of an application utilising the Carousel service is a 'ticker-tape' type service in which the data is
provided to the user repetitively and updated at certain times to reflect changing circumstances.
• Television (TV) service
The Television service is an MBMS service consisting of synchronised streaming audio and visual components.
5 High level requirements
5.0 General
MBMS user services are services an operator may provide to subscribers. MBMS user services use the capabilities of
MBMS. The operator may provide such services on his own or in collaboration with third party service providers. In
addition, an MBMS user service may be provided to the operator's own subscribers and/or to inbound roaming
subscribers from other operators.
MBMS User Services
MBMS user services are based on broadcast- or multicast services, which are defined in TS 22.146 [2].
MBMS user services shall be bearer agnostic to enable access via generic IP access systems.
An MBMS user service may use one or more broadcast- or multicast services at a time within the MBMS service area
bound to this user service.
Note 1: A single broadcast- or multicast service can only have one broadcast- or multicast session at any time
within the MBMS service area bound to this user service. A broadcast- or multicast service may consist
of multiple successive broadcast- or multicast sessions. (see TS 22.146 [2])
Note 2: As part of the same multicast service, it should be possible for the operator to provide the UEs with
multiple successive sessions with different quality-of-service for each session. (see TS 22.146 [2])

3GPP TS 22.246 version 15.0.0 Release 15 8 ETSI TS 122 246 V15.0.0 (2018-07)
It shall be possible for an MBMS user service to make use of different application independent MBMS transport
services at different times or in parallel. The MBMS transport services used may vary for instance in QoS parameters or
target broadcast or multicast area.
It shall be possible for one application independent MBMS transport service to be used by more than one MBMS user
service at a time.
If an MBMS user service makes use of several application independent MBMS transport services then these may only
consist of either broadcast or multicast services, but not of a combination of both.
Note: The combination of broadcast- or multicast services in future releases is FFS
When necessary, within a single MBMS user service, it shall be possible to synchronize the media sessions.
NOTE: For different application independent MBMS transport services to support a single MBMS user service it
may be necessary to logically link the transport services to each other, as illustrated in the figure for the
audio- and video session of MBMS user service X.
The UTRAN, GERAN and E-UTRAN accesses shall provide protection a
