Critical Broadband

The Critical Communications Broadband Group (CCBG) is a working group of the TCCA tasked with driving the development and adoption of common, 3GPP mobile broadband standards and solutions for users who operate in a mission critical or business critical environment. The CCBG has formed relationships with a wide variety of user and operator groups from around the world that have common aims.

The CCBG’s goals are to enable all Critical Communications users to access their information systems and applications, reliably, and at broadband speeds, on their professional mobile devices, wherever they are and whenever they have the need. This will ensure that critical LMR users have the right tools available to undertake their increasingly complex role and that resources are used in the most efficient manner possible.
The creation of the necessary standards and technology by 3GPP is only part of the solution. Delivering services and products that take advantage of such capabilities in a timely, cost effective and affordable manner is also a significant task.

TCCA has also taken the initiative to form a critical communications Broadband Industry Group (BIG), a TCCA Working group formed to encourage broadband vendor cooperation in the development of common global critical communications solutions. The BIG will work closely with TCCA’s Critical Communications Broadband Group (CCBG). These TCCA initiatives will help the co-ordination of critical communications standardisation efforts in 3GPP together with the public safety agencies and operators, in line with the CCBG goals and TCCA’s Market Representation Partner role in 3GPP.

The aim of the CCBG is to enable all mission critical and business critical users to access their information systems, intranet and internet at broadband speeds using their professional mobile devices wherever they are and whenever they have the need. This broadband capability should meet the specific needs of the user in the same way that critical voice and narrowband data services are currently delivered by technologies such as TETRA, Tetrapol, P25 and others.

TCCA is a 3GPP Marketing Representation Partner MRP). Internationally the 3GPP consortium is making progress with the releases of standardised mission critical Broadband technology including interoperability testing where the TCCA plays an active role through its Critical Communications Broadband Group (CCBG) and the Broadband Industry group (BIG).

The TCCA and the ACCF main goals are to drive the development and operation of critical mobile and broadband standards and solutions for public safety and all other critical communications users with a focus on standardised critical broadband and the transition from Narrowband critical technologies into one common 3GPP standard for critical Broadband solutions (LTE/4G and 5G).

Interoperability/MCX Plugtests and Certification – TCCA participates in the MCX Plugtests/interoperability testing events of critical Broadband (LTE 4G/5G) with ETSI and 3GPP members and the Global Certification Forum (GCF) has signed a Memorandum of Understanding with TCCA in 2018 that pledged to advance developments and certification in areas related to 3GPP mission critical services. The recent (2019) MCX Plugtests event occurred in Kuopio, Finland, in September 2019 that had 117 participants performing 1,800 test cases across more than 200 test sessions. Those sessions tested MCPTT, MCVideo, MCData, floor control, mission-critical bearers handling, multicast and more. Those tests had an overall success rate of 95%.

2020 MXC Plugtest – ETSI will host its Fifth Mission Critical Services (MCX) Plugtests event remotely from 21 September to 2 October 2020. The event was originally planned to be a face-to-face event in India but was changed to remote testing because of the COVID-19 pandemic, ETSI Project Manager Saurav Arora said during a webinar sponsored by ETSI and TCCA.

The fifth MCX interoperability event will focus specifically on over-the-top (OTT) testing that will be the first MCX Plugtests event to test railway-oriented capabilities. Railway features that will help enable a Future Railway Mobile Communications System (FRMCS) were included in Third Generation Partnership Project (3GPP) Release 15.The event will feature three test streams: mission-critical OTT testing, FRMCS OTT testing and test tools for conformance or audio quality testing.

MISSION CRITICAL OPEN PLATFORM – TCCA collaborates with the Mission Critical Open Platform (MCOP) https://www.mcopenplatform.org/ which is a collaborative project with the financial assistance award 70NANB17H151 from U.S. Department of Commerce, National Institute of Standards and Technology through the Public Safety Innovation Acceleration Program (PSIAP). MCOP aims at facing the challenges of the new MCPTT complex ecosystem through the definition, development and validation of a MCPTT UE Open Platform (MCOP) that identifies neat interfaces between the different technologies in the UEs, reduces the integration efforts and removes the entry barriers.
