Foreword
This Technical Report has been produced by the 3rd Generation Partnership Project (3GPP).
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 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;
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.
Introduction
SA1 has summarized service requirements in TS 22.101 [13], clause 32 for TV Enhancements.
According to TS 22.101 [13], clause 32.1, "3GPP enhancement for TV service support is a feature whereby 3GPP
networks can provide unicast and broadcast transport, referred to as "TV transport services", to support distribution of
TV programs. TV transport services can support the three types of TV services – Free-to-air (FTA), Free-to-view
(FTV), and Subscribed services. Each type of TV service has different requirements in order to meet regulatory
obligations and public service and commercial broadcaster's requirements regarding content distribution, hence many
requirements captured below are optional to implement depending on the type of TV transport services an MNO
chooses to offer."
There is interest for the TV industry to be able to deliver broadcast television (TV services) to connected consumer
devices (smartphones, tablets and TVs) anywhere, by using cellular networks.
Audio/Video content is already a significant and growing traffic type. There is an opportunity to leverage the support
for this content, and 3GPP delivery methods such as eMBMS, to provide TV broadcast and on-the-go TV/video
services:
- There is an interest from Over-the-top (OTT) TV/video service providers to be able to reach their customers
regardless of location, and available access technology, particularly when the consumers have cellular access but
not access to a broadcast TV signal (if that signal exists at all).
- There may be opportunities in the near future for LTE-based cellular TV broadcast services, in particular, the
free-to-air TV service in some regions of Europe.

1 Scope
The present document collects use cases, recommended requirements, architectural considerations, gaps, and
optimization potentials for PSS and MBMS User Services in order to enable Television Services on top of PSS/MBMS
User Services and MBMS bearer services. The present document also provides conclusions and recommendations for
normative work.
