3GPP Release 14 to Define MC-Video and MC-Data

PS-LTE First Reponders







Public safety and government agencies around the world recently came together to define and push forward the future of LTE Broadcast for Mission Critical communications.

There is strong pressure from around the world, as threat levels continue to persist. Government agencies are demonstrating the desire to move towards richer mission critical applications that include MC-Video and MC-Data.

The 3GPP SA6 working group has defined the under-pinning functional LTE architecture, as a pre-cursor to Release 14. The group will then define specific MC-Video and MC-Data protocols and interfaces by April-June 2017, in time for the availability of Release 14.

First responders and public safety forces deserve the best modern tools to protect themselves, and make our communities safer. Using the same LTE Broadcast technology already in use in B-C services like live mobile TV or sports event broadcasts, to securely deliver video and large files in real time to a group of 500 responders, is absolutely necessary.

Special Forces looking for a suspect can greatly benefit from communications based on an LTE Broadcast network. For example, a suspect was last seen at a gas station. High definition pictures taken by the surveillance cameras are immediately sent to all members of the search team. The speed at which the information appears on the responds’ mobile devices and the clarity of the images make it easier to get a good facial recon and details of the clothing.

Local fire departments, police, and hazardous material response units are deployed and coordinate their efforts after the derailment of a hazardous material carrying train. As drones fly over the scene, valuable HD videos information is sent back to the several units so they can assess the danger level and how to best move in. The video transmission is equivalent to watching a movie in HD, and gives the respondents the detailed information they need.

In these two scenarios, critical information is shared in real-time, between the responders without congesting the network. The new Release 14 specifications will also address interoperability concerns with the legacy emergency response networks Tetra and P25, which provide mainly Push-To-Talk capabilities. Stay tuned for more information on Release 14 as it continues to be defined.
