5 Steps to critical broadband in a nutshell the Finnish view Steps Take care of critical voice and messaging services over VIRVE TETRA Enable use of commercial data services in a secure way Manage and control subscribers in own broadband core Build own broadband radio coverage to relevant areas Extend critical TETRA voice services to broadband networks Once broadband services meet the same security, availability and coverage requirements as VIRVE TETRA dismantling can begin Critical conditions Dedicated spectrum Technology standards and implementation Commercial networks Proper licensing terms Critical traffic prioritisation Political decisions

6 Timeline the Finnish picture Priority and frequency lobby Time window for managed transition from TETRA Critical LTE voice and data Shared LTE for sparsely populated areas MVNO via commercial 3G/4G VIRVE TETRA-network develops VIRVE TETRA extra time TETRA technology is available and evolves

7 Goal of CCBG Critical Communications Broadband Group (CCBG) has been created to drive the development and adoption of common Mobile Broadband standards and solutions for users who operate in a Mission Critical or Business Critical environment

23 EC commissioned study - SCF

24 SCF - Report Conclusions (1) YES, if five conditions are met. 1. New regulations regarding commercial MNOs services must be enforced by each Member State s national regulatory agency (NRA). 2. Commercial networks have to be hardened and modified to provide over 99% availability 3. All this network hardening and extended coverage. must be accomplished at reasonable cost.

25 Simon Forge Report (2) 4. Hardened LTE networks must be able provide the different types of service required by each of the three sectors (*. Each sector uses broadband in quite different ways. 5. will commercial mobile networks be able to overcome ingrained Member State preferences for state controlled networks for applications that implicate public safety? *) PPDR, Utility, ITS

26 What have we been doing lately? 3GPP SA6 terms of reference Definition, evolution and maintenance of technical specification(s) for application layer functional elements and interfaces supporting critical communications (e.g. Mission Critical Push To Talk), including: Relevant application architectural aspects (including both network and terminal aspects) Definition of reference points for interactions between application functional elements Allocation of application functions to particular subsystems and elements Generating information flows between reference points within scope Identification of application protocols Based on clearly identified service and feature requirements and in co-operation with the other 3GPP WGs, identify application related architecture, functional elements, interfaces, reference points, and protocol aspects required to support critical communications that utilise 3GPP-based systems. Identify and provide application level functional requirements to other 3GPP WGs,. Design, specify and maintain application level requirements, architecture, interface(s) and protocol(s) to support interworking with other critical communication applications in collaboration with the relevant SDOs Initially Mission Critical Communications (e.g. MCPTT) will be the focus of work. 3GPP SA6
