Narrowband Communication
• European Public Safety Operators have signaled the availability
of their narrowband networks until 2025-2030
• For voice communication BDBOS will rely on TETRA until 2030
• Parallel deployment and use of broadband solutions is likely
Speech Communication is the most important technical operational resource
and group communication the most important functionality.

TOWARDS A STANDARDIZED SOLUTION
• Collaboration between national and
international organizations and
institutions is expanding
• Interfaces become more and more
important
• Standardization is paramount

National and international challenges
• What kind of management is required and necessary?
• How do we support groups consisting of TETRA and LTE
users?
• How does the operative-tactical workflow look like?
• Do we reduce or increase security?
• Do we need new End-User-Devices?

Why do we need an interface standard? Proprietary integration of systems
Benefits of interface standards
• Re-use the large installed base of legacy
LMR/PMR
• Provide a smooth migration path from
LMR/PMR networks to broadband Mission-
Critical Push-to-Talk (MCPTT)
• More flexibility, multivendor support
• Savings due to multiple suppliers
• Increased responsiveness
• Benefit from large LTE project expertise
• Integrated information exchange across PS
Offices and communication technologies
• Usages of LTE’s leading edge technology for
long life cycle of communication technology

• Features already introduced in Rel-15:
– Group (de-)affiliation , with group defined in MC system or in LMR system
– Interworking group creation, with users from MC system and LMR system
– Group regrouping
– Group calls over interworking groups
– Private calls between users in MC system and LMR system
– Interworking for emergency related procedures (emergency calls, emergency alerts, emergency state cancellation)
– Voice packet transcoding, codec reconciliation
– Interworking for one-to-one and group SDS
• Some unresolved issues: key management/encryption, group creation
• Received information from ETSI TCCE, on related study work ongoing within TCCE, and on results
of TCCE review of SA6 work

• Standard will only define MCPTT – LMR/PMR integration in Rel. 15 with content eventually moving to Rel. 16 (?)
• Even if this is a well-defined interface, it must be implemented and supported on both MC-PTT and LMR/PMR side to
provide a simplified integration
• LMR/PMR vendors not likely being highly motivated to support such interface. Customers have to push for it
• On the Nokia Group Communication (GC) side, we see a trend of simple RoIP GW launches. It will allow simple bridging
of MC-PTT groups to “any” PTT solution. Benefit: cost effective, but with limited scaling and no native security support
• More sophisticated GW solutions are expected to enter the market in 2018
• Even RoIP integration can be made more intelligent. Some LMR/PMR devices (e.g. for TETRA) provide interfaces that a
RoIP GW can control. This allows more efficient connection of MC-PTT and LMR/PMR PTT groups, as well as mapping of
more sophisticated features (PTT, Call Id, Group Selection, SDS, Distress Call).
• More intelligence and scalability can be implemented by using direct GW. These would tab the ISI and ISSI interfaces on
the TETRA and P.25 systems respectively. Such projects have usually significantly more integration work
• In all cases, GWs allow customers to utilize their investment in LMR/PMR and implement gradual migration strategy
Key Considerations
Critical communications for all professional users
Operational Aspects
Mentura Group 2017
User services are connected – even if the networks are not
A user has a radio and a data device for different needs
Situational awareness can rely on both systems – core apps network agnostic
Voice communication is network agnostic
Data available from and to all networks. Smart apps can adjust to the situation.

LTE-TETRA migration: USE CASES
Terminal per user Basic services interconnection
Introducing LTE terminals
without any TETRA connection1 (tetra or LTE) No
User with two terminals 2 one for basic services, one for
data
No
Dual technology terminals1 data are automatically routed
to LTE while basic services are
automatically routed to TETRA
No
Dual technology terminals with
interconnection1 YES: basic services may be handled trough
TETRA or LTE
Dual technology terminals + fall
back mode1 YES: LTE network is used as back up of TETRA
and TETRA is used as back up of LTE
4G operator extending
networks with TETRA1 (TETRA or LTE) YES: the operator wants to add TETRA BS over
existing 4G radio sites and use existing central
4G equipments (HSS, billing,..)

DATA BASE
Each database contains location of any terminal
For any internetwork communication, the calling
party must declare the destination network
The common database contains the network (technology)
and the location in the network of any terminal.
Any incoming call request is directly routed

In both cases, TETRA and LTE adresses must be mapped.
With HSS as common data base, it is simplified while any TETRA
terminal have a standard NMI adress mapped to its own TETRA adress,
that leads to use ‘virtual ‘SIM card
