The provision of reliable and guaranteed communications between first responders is essential in ensuring that people are kept safe and damage is avoided, or where possible mitigated. This reliable and guaranteed communication is referred to as MC (Mission Critical) communications.
Users of MC communications are not simply restricted to emergency services, such as the police, ambulance or fire services. It also includes non-MC industries, such as industrial and nuclear plants, transport and utilities. Security staff at events or stadiums, train stations and airports also provide additional user groups.
MC (Mission Critical) services will provide numerous capabilities and functions that can be delivered to groups and users depending on their requirements. This includes Push to Talk capability, data exchange and video streaming.
MCPTT (Mission Critical Push to Talk)
MCPTT is designed to replace the current public safety communication networks. It will leverage key LTE enablers, including GCSE (Group Communication System Enablers), ProSe (Proximity Services), MBMS (Multimedia Broadcast/Multicast Service) elements and also the IMS (IP Multimedia Subsystem) network. The 3GPP standards for MCPTT capabilities provide the necessary features to deliver functionality that is found in the traditional narrow band radio networks, such as the legacy TETRA and P25 systems.
MCData (Mission Critical Data)
MCData focuses on non-voice and non-video traffic. It will enable the exchange of data using SDS (Short Data Service), the acquisition and exchange of files, and database queries. MCData will also enable computer aided dispatch to be provided and allow for additional features such as event management, robot control, intelligence gathering and dissemination.
MCVideo (Mission Critical Video)
MCVideo users will be able to make a video call as a group conference call or direct to another user. There is also the ability to stream video to groups of users from a robot or drone, or a security camera.
MCVideo service includes providing users with the ability to capture and stream video securely. There is also the ability to encode and store the associated video information. Processing of the video information will allow for video frames to be annotated and features within the footage to be recognized. In support of mission critical and public safety functionality group sessions, end-to-end confidentiality, emergency type communications and low latency performance are available.
