The proliferation of
on-line media applications and digital entertainment have contributed to the exponential
growth in Multicast-aware technology. This technology enabler has facilitated
the delivery of best effort Quality of service (QoS) to a group of consumers on
the global network. In recent times, the Internet Content consumers’ Quality
of Experience (QoE) grown from 40%
in 2014 to 80% in 2016 based on Multimedia Broadcast Multicast service
delivery.
A little background on Multimedia Broadcast Multicast services reveals that Multimedia Broadcast Multicast services
is a point- to-multi-point interface specification for existing and upcoming 3GPP cellular networks which is
designed to provide efficient delivery of broadcast and multicast services both
within the cell as well as within the core network. The broadcast transmission
across multiple cells. It defines transmission by a single frequency network configurations.
Target applications includes mobile TV and radio broadcasting as well as file
delivery and emergency alert.
Deployment: MBMS Mobile broadcast
technology has never been deployed by any operator in the world as suppose to
other technology such as DBBH, ATSCMHIH DBTMM. Various mobile technology in the
UK had conducted trials for MBMS based mobile TV. There is no indication that
this trials resulted in any commercial deployment. In 2013, Verizon was the
first operator to anounce the Bolunchi MBMS services.In 2014, over its LTE
Networks. eMBMS is the LTE version of MBMS. AT&T subsequently announce
plans to use the 700MH lower D block licences it acquired in 2011 from qualcomm
for an LTE broadcast service.
In 2014, several major operators
are lining to deploy and test the technology. In July 2014, Nokia networks
demonstrated the use of LTE broadcast to replace broadcast traditional digital
TV. This use-case remains controversial as some study are doubting the
capability of LTE broadcast to address this use-case efficiently in its current
version. In August 2014, ericsson and pokontel successfully tested the LTE
broadcast by streaming the opening game of 2014, world volleyball championship
to hundreds of guest in euro on majesty trademark national stadium in Poland on
August 30th. 2015. Competing technologies of MBMS
include DBTHDMB DBBHBSM and media flow.
However, due to spectrum scarcity
and cost of building new broadcast infrastructure, some of these technologies
may not be viable. Media flow has been deployed in the U.S by Verizon in
relationship with Media flow U.S.A in corporated. However, the service was shut
down in early 2011. DMBMDH trials has been on-going for more than a year now. During the football 2006 championship in
Germany. Always proprietary CMBS is a precursor to the multimedia Broadcast
Multicast service. It was specified in 3gpps 6 using the existing UMTS
infrastructure and real-time streaming protocol.
Technical
Description:
The MBMS feature is split into the MBMS bearer service and the MBMS user
service and it been defined to be offered over both UTRA and LTE. MBMS bearer
services include the multicast and broadcast mode but only the broadcast mode
is available over LTE. MBMS bearer
service uses IP multicast to addresses for the IP flows. The advantage of the MBMS bearer service compared
to unicast bearer services is that the transmission resources in the core and
radio network are shared. 1MBMS packet flows is replicated by GGSN, SGSN and
RSC’s. MBMS may use an advanced counting scheme to decide whether or not Zero,
one or more dedicated radio channel leads to a more efficient systems usage
than one common radio channel. UTRAN MBMS offers up to 256kbits per MBMS bearer
service between 800kbits and 1.7 with scell band. The actual cell band depend
on the UE capability. MBMS offers between 32kbits and128 kbits. Up to 4 GSM
time slot may be used for one MBMS bearer services downlink direction. The
actual data rate of traffic flow depends on network dimensioning.
The MBMS user services basically
the MBMS services Offers adopt the streaming and download delivery method. The
streaming delivery method can be used for continuous transmissions like the
mobile TV services. The download method is intended for euroE download euro services
To increase the transmission
reliability, an application RFC code may be used. MBMS has been standardized in
various methods of 3GGP and the first place standard on UMTS release 6. Release
6 was functionally frozen by the third quarter of 2004 and practical network
implementations may be expected by the also end of 2007 at the best functional
mobile terminal services. EMBMS has been standardized by various groups’ 3GGPs
part of LTE release 9. The LTE version of MBMS referred to as multicast broadcast
singular frequency network support based on FDM wave form and similar to other
broadcast solutions such as DBBH. 3GGP technical specification MBMS bearer service.
