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.


15

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?Timo Bakker – NOKIA

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

• Work initiated with a study in Rel-14 timeframe (May 2016)

• Normative work started in July 2017 and expected to complete by December 2017

• Interworking for PTT and data SDS

• 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

3GPP Release 15Work status in 3GPP TSG CT1


2626

• 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


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,..)

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
