9 Overview Project 25 (P25) Land Mobile Radio (LMR) o Standard for the design and manufacture of interoperable digital two-way wireless communications products. o Developed in North America with state, local and federal representatives and Telecommunications Industry Association (TIA) governance, P25 has gained worldwide acceptance for public safety, security, public service, and commercial applications Long Term Evolution (LTE) Cellular o Standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. o It increases the capacity and speed using a different radio interface together with core network improvements. 9

10 Overview FirstNet - Public Safety Broadband Network o The First Responder Network Authority of the United States was created under the Middle Class Tax Relief and Job Creation Act of 2012 as an independent authority. o FirstNet is a nationwide wireless broadband network being built for first responders. o The First Responder Network Authority is the federal entity charged with overseeing the creation and delivery of the FirstNet network. It is housed within the Department of Commerce, National Telecommunications and Information Administration. o AT&T was awarded the contract in April 2017 to build the LTE broadband network. o The agency s role is to ensure AT&T delivers on the terms of its contract and creates a network that meets the needs of public safety now and into the future. 10

11 Existing Radio System Government agencies rely on Land Mobile Radio (LMR) systems to support voice two-way radio communications for personnel in the field to communicate. Radio Systems are complex terrestrially-based, wireless communications systems. Not all radio systems are the same. The configuration of the radio system makes it unique. When developing a radio system there are many elements involved. However, some of the primary elements are: o Capacity - # of talkpaths, # of devices, avg. length of conversation o Frequency VHF, UHF, 800 MHz, 700 MHz o Coverage street level, inside of buildings (density level) for jurisdiction o Type Conventional, trunked, single site, multi-site, analog, digital, encryption, local control, programming processes for interoperability o Reliability the performance of the system under a stated condition for a specified period of time. o Cost Original purchase price, plus, on-going operational and maintenance costs 11

12 Existing Cellular Usage Government agencies utilize Cellular systems to augment existing forms of communication Mobile Data Terminals (MDT) laptops in vehicles NCIC Lookups Local Computer Aid Dispatch (CAD) Systems Access Shared Data Information s Internet Cell phones Voice Calls Data transmissions» s» Internet 12

13 Reliability Equal or better Coverage Cost Equal or better Less money or more services Capacity Equal or better Frequency Type Government Users LTE Expectations Band 14 plus commercial bands Local control & seamless transfer from carrier to carrier for interoperability 13

14 Government Users LTE Initial Deployments Replacing existing MDT service provider equipment Interworking with existing P25 systems Increasing coverage for non-critical users regularly going outside of jurisdiction Increasing coverage gaps for non-critical users within existing systems Convergence of new devices (testing phase) 14

15 Government Users LTE Challenges/Opportunities Overcoming, State and Local government agency contracts with carriers that are not AT&T(FirstNet), which currently indicate they have enhanced coverage. Since there are currently, no established standards or agreements for the following, they should be developed. cellular commercial carriers to ensure prioritized interoperability for critical public safety applications and access between carriers. cellular commercial carriers to ensure seamless access and transferring of data between carriers. 15

16 Government Users LMR/LTE Interworking LTE to operate between carriers for public safety mission critical broadband data LTE to operate between carriers & FirstNet for public safety mission critical broadband data LTE/FirstNet to develop interoperable capabilities with P25 systems 16

17 Government Users LMR/LTE Interworking There is a place in Public Safety for LMR & LTE systems Utilizing the best of both technologies 17

19 International Wireless and Communications Expo Las Vegas, Nevada March 7, 2019 Business Model Deployment models for P25 & LTE MCPTT Interworking Jeremy Elder, Director of Integrated Platforms, Harris Presented by: PTIG - The Booth

20 Introduction Major trends advancing P25/LTE MCPTT Interworking and supporting network evolution to P25 with 3GPP LTE: o Migration of proprietary & analog LMR technologies to P25 o Legislation & spectrum policy support for public safety broadband o Standards advancement (discussed later today) o Major carrier investments in 3GPP LTE MCPTT capabilities Objective: Discuss deployment models for P25/LTE MCPTT interworking and describe their trade-offs These P25/LTE MCPTT deployment models are present in the marketplace today. This presentation will focus on models rather than on specific examples of implementations. 20

21 A general model for 3GPP standards deployment with P25 interworking Standardized interfaces between 3GPP MCPTT services and between MCPTT and LMR (P25) networks are enablers 21

22 Carrier-centric deployment model PTT Service and LTE subscription are offered as a bundled service with interworking interface available 22

23 Carrier-centric deployment model Key Points: Carrier offers MCPTT and LTE subscription as a bundled service Carrier provides interworking interface that can be used to connect a P25 system Benefits: OPEX model with low initial cost of entry Potential cost benefits with bundled packages Native interoperability with other PTT service members Potential Challenges: Limited local control Interop with agencies subscribing to a different carrier 23

24 Cloud deployment model PTT over LTE networks as-a-service 24

25 Cloud deployment model Key Points: PTT service subscription and LTE service subscription are obtained from different vendors PTT service provides interworking capabilities for P25 Benefits: OPEX model with low initial cost of entry PS agency has choice in LTE providers & PTT service providers Potential Challenges: Establishing QoS over the LTE network Interoperability with agencies that subscribe to a different PTT service 25

26 On-premise deployment model PTT service co-deployed with P25 service and operating over LTE network. 26

27 On-premise deployment model Key Points: PTT and P25 services are procured from the same vendor PTT and P25 services are jointly deployed on an agency s network Benefits: Choice in LTE providers & PTT service providers High amount of local control as entities own the service Potential Challenges: Initial capital investment & ongoing maintenance costs Establishing QoS over the LTE network Interoperability with other PTT services 27

28 Summary P25/LTE MCPTT Interworking Deployment Models P25 migration & P25/3GPP LTE network evolution are both underway Multiple deployment models are possible, each with different trade-offs: o o o o CAPEX investments versus OPEX costs. Choices for LTE provider, PTT provider, and devices Tiers of Local Control & Quality of Service Interoperability challenges depending on offered capabilities Availability of multiple deployment options enables agencies to adopt the solution that best meets their needs 28

31 ATIS and TIA Background (1 of 2) TIA and ATIS Memorandum of Understanding dates back to 2006 in which the two SDOs agree to jointly sponsor and work cooperatively in the development of joint standards documents that are of mutual interest. ATIS Alliance for Telecommunications Industry Solutions is a Standards Development Organization (SDO) develops technical and operational standards and solutions for the ICT (Information and Communication Technologies) industry (members include manufacturers and user agencies such as APCO) TIA Telecommunications Industry Association is a Standards Development Organization (SDO) that develops voluntary, consensus-based industry standards for a wide variety of ICT products (members include manufacturers and P.S. Agency reps) 31

32 ATIS and TIA Background (2 of 2) TIA and ATIS began work on interworking of LTE Mission Critical (MC) and LMR services in 2012 Joint Project Committee known as JLMRLTE This included Tetra, P25 Conventional, P25 Trunking and TIA-603 based Conventional Analog FM service In 2014, the JLMRLTE agreed to postpone further work in JLMRLTE until the LTE part of MCPTT work in 3GPP is more developed In 2015 work resumed that created documents defining klmr terminology and high level service descriptions Provided to 3GPP in 2016 In December 2017, JLMRLTE work resumed Primary participants are 3GPP member representatives, TIA member representatives, Firstnet, AT&T 32

33 ATIS/TIA JLMRLTE Status (1 of 7) Current ATIS Issue statement (WTSC-JLMRLTE R001) excerpt: This issue statement proposes that ATIS WTSC (SN and RAN) initiate work with TIA TR-8 (TR-8.8 subcommittee) to develop joint ATIS/TIA specification(s), with ATIS as the lead Standards Development Organization (SDO). Joint ATIS/TIA specification(s) on Use Cases, requirements, architecture, call/message flows, and implementation guidelines would be developed that define interworking of standard interfaces for published or future TIA LMR standards to the 3GPP interworking specifications. The JPC shall coordinate with 3GPP and TIA committees to identify and address gaps and evolve those standards as necessary. in support of this issue. As application and service protocols evolve, the work should accommodate, in so far as is possible, interoperation of new broadband public safety features with new features of TIA-102 and TIA-603 conventional FM systems. 33

34 Current work item WTSC-JLMRLTE R001 title: Study of Interworking between P25 LMR and 3GPP (MCPTT) Mission Critical Services Scope excerpt: ATIS/TIA JLMRLTE Status (2 of 7) This document contains scenarios and considerations for the use of a 3GPP Release 15 Interworking Function to enable interoperability of services between a 3GPP MC system and a TIA-based LMR system. For the purposes of this document there are three distinct TIA-based LMR systems that will be examined, namely: P25 trunking, P25 conventional, and TIA-603 analog conventional FM. NOTE: This document is intended to describe how that 3GPP Interworking Function may be used to enable interoperability of those services that are common between 3GPP MC systems and each of the three TIA-based LMR systems mentioned above. Interoperability of services between 3GPP MC systems and TETRA-based LMR systems are outside the scope of this document. 34

35 ATIS/TIA JLMRLTE Status (3 of 7) 3GPP Release 15 and 16 documents define: Interconnection of 3GPP LTE Mission Critical Systems Interworking between LTE and non-lte Systems The 3GPP Interworking architecture defines an Interworking functional entity (IWF) Adapts LMR Systems to mission critical systems via the IWF interface and supports interworking between LMR systems and mission critical systems. From the 3GPP side, the IWF acts as another MC System From the LMR side, the IWF acts as another LMR System The IWF is the functional entity responsible for conversion of media and control signaling between LTE and LMR technologies 35

36 ATIS/TIA JLMRLTE Status (4 of 7) High level functional model found in the JLMRLTE document: Conventional FM LMR system L603 IWF IWF-1, IWF-2, IWF-3 MC service TIA-102 LMR system L102C/ L102T L603 TBD interface to Conventional analog FM system L102C TBD interface to P25 Conventional System L102T TBD interface to P25 Trunking System IWF-1, -2, -3 Interfaces to 3GPP Mission Critical (MC) System Services NOTE: IWF in this picture = LMR Interworking Gateway device(s) that connect LMR and LTE standard interfaces to enable interoperability (orange box in previous deployment model slides) 36

37 ATIS/TIA JLMRLTE Status (5 of 7) Current philosophy of the JLMRLTE document: Describe how common services (features) may interwork (interoperate) o Do not prescribe a particular LMR interfaces to the IWF although ISSI/DFSI are likely candidates o Do not prescribe specific 3GPP or TIA messages to or from the IWF o Do not prescribe specific TIA devices that may interface with the IWF High level identification of message translations that are needed for interworking High level identification of media translations that are needed for interworking Identify issues For Future Study (FFS) that must be resolved 37

38 ATIS/TIA JLMRLTE Status (6 of 7) Current JLMRLTE document Table of Contents includes: oarchitectural considerations and assumptions (active work) ofunctional models (placeholder) oaddressing (placeholder) odeployment models (placeholder) ofeatures and scenarios (active work) Architectural considerations and assumptions section provides high level descriptions of how services operate Features and scenarios section provides descriptions and generic message flows for establishing, maintaining and terminating interworking services 38

39 ATIS/TIA JLMRLTE Status (7 of 7) ATIS intends to publish some form of the current working document in June 2019 The completion level of the current document by June 2019 is TBD The level of detail (architecture level vs. protocol level) that ATIS will eventually provide is TBD The JLMRLTE has requested the submission of discussion papers from the participating members that are intended to further define the breadth and depth of documents to be produced by the JLMRLTE Standards work in 3GPP or TIA may be necessary to enable implementation of 3GPP LTE MC and TIA LMR service interworking defined by the JLMRLTE documentation 39
