Multi Operator Neutral Host Innovation Showcase

PNO Private Network Operator
LTE (& 5G) networks are SO MUCH better than WiFi!
But how can a ‘non-operators’ deploy and manage LTE that real people can use?
My objective is to…...
...make setting up and using a Private LTE Network as easy as deploying a WiFi Access point…..
Drivers for Change
Big problems are becoming less...
Software Based Networks
The Demise of Proprietary Hardware Platforms
Cloud based infrastructure offers● Greatly reduced cost● Shortened deployment times● Massive scalability● Rapid development/evolution
AND
Open Source - which *is* scalable, reliable and supportable!
Spectrum
Spectrum used to be MAJOR Gating Factor for MNO entry
● Smart Shared Spectrum Management○ LSA/DSA○ Secondary use on
non-interference basis● Licence free operation (MuLTEFire)● Operator Spectrum Leasing
Cost/Availability of Spectrum directly linked to power levels/cell size
Licensed Shared Access (US)
Dynamic Shared Access
SAS - Spectrum Access System
Cells report
● Location● Operating Parameters● What they can hear
SAS issues Lease
Like DHCP, but with blocks of spectrum rather than IP addresses
Spectrum - Detailed View● DECT Guard Band (2 x 3.5 MHz) - 1800 MHz (Band 3) - Secured Today (UK/NL)
● Sub-licenced LTE 800 (2 x 30 MHz) - 800 MHz (Band 20) - Applied for secondary use on non-interference basis
● TDD Bands - due for imminent release - some if not all as Licenced Shared Access (LSA) or Dynamic Spectrum Access (DSA)○ 2300 MHz (Band 40) - Release imminent○ 3400 MHz (Band 42) - Release imminent in EU, Available in US○ 3500 MHz (Band 43) - Release imminent in EU, Available in US
● Licence Free [MuLTEfire] (Band 46) - 5200 MHz (775 MHz - shared with WiFi) - Available today, but no support yet in User Equipments
● 700 MHz Band (Band 28) (2 x 30 MHz + 20 MHz SDL) - Release 2018
Identity and Authentication
The Subscriber Identity Module (or SIM)The SIM contains network-specific information used to authenticate and identify subscribers on the network.
● ICCID - integrated circuit card identifier● IMSI - International Mobile Subscriber Identity ● Authentication Key([s] (Ki), ● Local Area Identity (LAI) ● Plus carrier-specific data such as the● SMSC (Short Message Service Center)
number, ● Service Provider Name (SPN), ● Service Dialing Numbers (SDN),● Advice-Of-Charge parameters and ● Value Added Service (VAS) applications
Multi-IMSI SIMsNormally SIMs contain ONE IMSI and associated crypto key variables
More sophisticated SIMs (such as those from Truphone®) contain multiple IMSIs (and possibly multiple sets of crypto keys)
At any time only ONE IMSI is active
Multiple user profiles (and phone numbers) can be mapped concurrently to the active IMSI
Further SIM DevelopmentMulti-IMSI/Multi-Crypto Key Variable SIMs allow authentication to be carried out by different Home Subscriber Servers (HSS)
The signalling channel (always on and always free) can be used for independant comms between SIM and mobile network core
SIM Socket - micro web browser on SIM
Apps running on SIM independant of handset

Challenges
The Dangerous Demo..!
TAD Summit History
The Challenge
● Following TAD Summit 2013 (Bangkok) it became apparent that in order to demo most of the TADS apps, some form of underlying network would be required
● ‘Bet you can’t do that!’
● ‘Bet we CAN!’
Accomplishments
● 2014 (Istanbul) - First iteration - Truphone, Canonical, Telestax and Metaswitch
● 2015 (Lisbon) - added multiple network apps and demonstrated massive scalability/refactoring
● 2016 (Lisbon) - introduced RAN (using software defined radios
TAD Summit 2017 - Dangerous Demo
The Objectives
● All existing components from previous Demos, PLUS:
● Add PRODUCTION READY 4G Radio Access Network (Accelleran)
● Add live IMS (SIP and DIAMETER) exchange with Public Mobile Networks
● Show full Multi Operator Neutral Host operation using audience phones as part of demo!

What are doing in MONEH project
• Allowing Subscribers to attach to our HSS• Giving access to IMS Network for data connection
Kamailio as an IMS Core• Rock-Solid SIP-Proxy
– Talking SIP since 2001 (aka “SER” – the SIP Express Router)
• OpenIMS-Core by the Fraunhofer Institute– Standards compliant
– Focused on Test-Beds and R&D
– Also based on SER (Started in 2004)
• OpenIMS-Core and Kamailio merged in 2010
Kamailio as an IMS Core (2)

Rural Not SpotsResolving the Digital Divide
The Chalke Valley - AONB
Defining the ‘Not-spot’● Not-Spots – areas where there is currently no coverage available● Partial Not-Spots - areas which have coverage from some but not all of the 4
major mobile networks
Technology and Band Signal Threshold
2G - GSM [900/1800 MHz] -93 dBm
3G - UMTS [2100 MHz] -103 dBm
4G - LTE [800 MHz] -115 dBm
