Expway, the LTE Broadcast expert and leader, Bittium, the manufacturer of reliable and secure Bittium Tough Mobile, and innovative MC-PTT (Mission-Critical Push-To-Talk) provider Nemergent, today announced the successful demonstration of a 3GPP Rel13 compliant end-to-end multicast group calls with Mission Critical eMBMS (evolved Multimedia Broadcast Multicast Services) bearers.
The three companies integrated their products over standard compliant interfaces on the core side (MB2-C/U) and between the MC-PTT Application Server and Application Clients. This important milestone opens up new opportunities for experimentation and field trials, eventually aimed at increasing the safety, and enhancing the experience of first responders while at the same time optimising the use of radio resources.
Public safety agencies are starting to evolve their narrowband LMR (Land Mobile Radio) technologies to LTE (Long Term Evolution) based solutions. LTE is 3GPP standards based and used as commercial cellular network technology worldwide and it has been proven to offer high performance, spectrum flexibility and security. With MC-PTT as part of the LTE 3GPP Release 13, LTE has emerged as the perfect technology for mission critical push to talk.
“Nemergent has worked hard to develop carrier-grade enhanced-push-to-talk technology, and is the first to support MC-PTT over LTE Broadcast”, said Claude Seyrat, Expway co-founder and CMO. “Bittium is the first device manufacturer to offer Push-To-Talk, including group calls, over LTE Broadcast”.
Multicast transmission is a mandatory feature to provide efficient group communications over mobile broadband networks. eMBMS is the technology that provides multicast communications in LTE networks for different applications including video/audio broadcasting and mission critical communications.
“We are fully committed to support mission-critical-push-to-talk (MCPTT) technology” said Jose Oscar Fajardo, CEO at Nemergent Solutions SL. “Integrating our MCPTT product with Expway’s LTE Broadcast server and client middleware, and with the Bittium devices is a logical progression of the company’s commitment to interoperable communications. “
In mid 2016, the 3GPP made a big leap forward towards standardized mission critical communications with the definition of an MC-PTT suite of protocols in its Release 13. The resulting ecosystem includes MC-PTT Application Servers, core configuration and management servers, and MC-PTT mobile devices. Aimed at fostering the deployment of commercial MC-PTT solutions, one of the critical aspects is assuring the interoperability of the eMBMS anchors between the MC-PTT service and the LTE network components both at the server and client sides.
“It was our pleasure to work with companies like Expway and Nemergent in this demonstration” Said Tero Savolainen, Vice President in Bittium. “With reliable and standards based solution, agencies can adopt broadband devices and services for their first responders and also utilize the potential besides MC-PTT, including video, situational awareness and other data applications “
