Mission Critical Push To Talk on LTE Networks

Mission critical push to talk (MCPTT) represents those capabilities that align with the requirements of public safety organizations as part of their rapid-response programs, specifically voice communication.  These include features such as high availability and reliability, minimal latency, the ability to support conferencing or direct communication, clear call quality, security, encryption,etc.  MCPTT is critical to ensuring that emergency calls go through with a clear call quality.

Historically, non-compliance and incompatibilities between vendors hampered MCPTT. According to the 3GPP Global Initiative, in 2016 application standards for MCPTT on LTE were established in the 3GPP Release 13, but continue to evolve to a consistent methodology for the protocol.  

It’s critical to be confident that equipment designed to support the MCPTT standard are capable of handling the volume of traffic that may occur during an event.  This includes simulating the variety of mobile radios and other devices that could potentially overwhelm the network.

Valid8 has delivered the first testing capability that combines LTE MCPTT and P25 ISSI load and conformance suites in a single solution.  The testing technology offers the flexibility of deployment through hardware provided by Valid8 or through a virtual machine (VM) deployment.  The solution leverages Valid8’s proven expertise for performance, conformance and load testing in telecommunication.

Ensure your technologies meet compliance standards.  Valid8’s testing suite offers reduced risk and peace of mind that, in an emergency, where seconds count, communications will be clear, reliable and secure.
