LTE Mission Critical Applications

TSG#65, Edinburgh, September 2014

3GPP has created a new Working Group to undertake specification work for applications in the mission critical communications space.

The 3GPP SA Plenary meeting (TSG SA#65), in Edinburgh this week, approved the creation of WG SA6, to initially focus on the Mission Critical Push to Talk (MCPTT) application in Release 13 while developing in to the generic home for all future 3GPP mission critical application work - as defined by stage 1 service requirements, on top of a common architecture.

The goal at SA#65 was to create an organizational setup that is equally attractive for all relevant stakeholders of this industry. To emphasise this, a liaison statement has been sent out by TSG SA, outlining the main tasks that have been identified for SA6 and noting the relationships between ongoing work in existing groups.

TSG SA#65 appointed Andrew Howell (U.K. Home Office) as Convenor for the new Group until formal elections are held. The December SA Plenary - TSG-SA#66 - is expected to formally approve the Terms of Reference of SA6, at which time the group will become operational.

3GPP supports High Efficiency Video Coding

3GPP Release 12 specifications now include support for the HEVC (High Efficiency Video Coding) video codec – H.265, providing a technical solution for highly efficient delivery of download, streaming and conversational video services.

Addressing the challenge of ever growing video traffic over mobile networks, HEVC provides a remedy for operators to increase quality of experience while at the same time reducing bandwidth consumption of video services, typically by a factor of 2 compared to the best technologies available prior to Release-12.

3GPP SA4 - the Codec working group - completed their study of the compression efficiency of HEVC in the context of 3GPP services by conducting objective and subjective tests, producing the 26.906 technical report to document the findings. Accordingly, the HEVC video codec is specified with decoding capabilities conforming to the Main profile, Main tier, up to level 3.1 thus allowing HD video services in 720p up to 25 or 30 frames per second. 


LTE meets the need in 3GPP

Edinburgh, September 16, 2014

3GPP has used a 4G (LTE) cellular connection during the 65th Plenary meetings in Edinburgh, from the 9th – 17th September, using the project’s own technology as the primary source of connectivity for the first time in a major meeting.


Interoperable Small Cells

ETSI has finalised a Report on the 2nd Small Cell LTE Plugfest, organised in partnership with the Small Cell Forum and held at the Orange Labs in Paris.

During ten days of testing 65 experts from a variety of organizations (26 in total) cooperated on debugging vendor solutions and used lab time to tackle potential ambiguities in the standards, which will help feedback fixes to the interface specifications (See the event Report, for “feedback on base specifications”).

Test sessions concentrated on S1, X2 and management interfaces, covering areas such as Security, Management, Voice Support via CS Fall-back Schemes, Voice and Video over LTE, Commercial Mobile Alert Systems and Self Organising Networks. One of the key areas of focus was the testing of multi-vendor mobility and SON in heterogeneous networks.
