1 Signaling for the Internet of Things Michael Senn Principal Technologist

2 Internet of Things Examples The Connected Car Infotainment Predictive maintenance for manufactures Regular and on-demand data communication between cars and central data centers Mobile Health Care Continuous, remote diagnostic service Regular and on-demand data communication between cars and central data centers Reduction in hospitalization costs Smart Power Meters Periodic monitoring of power consumption Regular and on-demand data communication between cars and central data centers Optimized power supply and price plans 2

3 Internet of Things Big Picture Exponential growth of smart devices covering Stationary Highly mobile High demand of Device-to-Server and Device-to-Device communication Reporting centrally Information sharing to users Strong requirement for devices with low power consumption Emerging new business models for vendors and service providers 3

4 What does it mean for Telcos Significant increase of subscriber base New service demands Explosion of associated signaling traffic Massive demand for cost-effective capacity expansion Deployment of extremely robust overlay networks Requirement to offer new and enhanced interfaces to 3rd party OSS and BSS Data Management and Analysis providing new customer experiences Lower ARPU per device Adds to Opex and Capex pressures 4

5 Internet of Things Network Impacts Functional Analysis Smart device triggering A/IuCS T5c 2G radio Gb/IuPS IuCS 3G radio MSC/VLR IuPS SGs D, E SGSN T5a High device T5b mobility & seamless roaming S6d S6a MTC-IWF Tsp, T4, S6m DSC S6, Cx, Sh S6n AAA Tsp SCS Traffic T4 prioritization, SMSC adaptive congestion GMSC control IW-MSC C, E, Gd 4G radio S1-MME S1-U MME S11 Gn/Gp, S4 Gx, Rx, Sy Traffic prioritization, PCRF adaptive congestion control PDN-GW S-GW S5/S8 GGSN Gr, Gd Gx, Gy, Gz HSS/HLR C, D, Gr, Gc STP Gc S6b High device mobility & seamless S/Gi roaming Strong growth of subscriber base Sy, Gy, Gz using device-specific Rf, Ro profiles CAP Cx, Sh, Rx, Rf, Ro Charging PDN e.g. IMS

6 Internet of Things Network Impacts How can TITAN help? 2G radio A/IuCS MSC/VLR Highly scalable, software-only platform combining HSS, HLR, DSC, STP, AAA & MTC-IWF Tsp T5c Perfect fit for overlay networks SCS Gb/IuPS D, E 3G radio 4G radio WLAN LPWN IuCS IuPS S1-MME SGs S1-U T5a Multi-protocol engine S6d SS7, Diameter & SIP SGSN Gr, Gd Any access supported T5b MME Gx, Rx, Sy S6a Gn/Gp, S11 S4 PCRF Gx, Pre-standard signaling Gy, support Gz for un-licenced spectrum radio access TITAN Complementary PDN-GW core network solution S-GW S5/S8 GGSN Gc S6b S/Gi CAP T4 C, E, Gd Robust & flexible traffic prioritization Sy, Gy, Gz and congestion control functions Rf, Ro Ready for the traffic explosion Cx, Sh, Rx, Rf, Ro SMSC GMSC IW-MSC Charging PDN e.g. IMS

7 Planning for Signaling Storms Manage Centrally Process Locally Core of the Core perfect for initial deployments Edge Computing manage the traffic explosion 2G radio MSC/VLR SCS 2G radio MSC/VLR TITAN SCS 3G radio SGSN TITAN SMSC GMSC IW-MSC 3G radio SGSN TITAN SMSC GMSC IW-MSC 4G radio MME Charging 4G radio LPWN MME TITAN Charging 7

8 Securing the IoT Network Avalanche of new devices accessing the network Not possible to certify all devices, all will not be well behaved Enforcing device profiles Smart meters should not be changing location esim impacts to the Authorization and Authentication procedures Handling of registration storms Gracefully handle high load signaling Traffic shaping Overload protection Profile fix up activities Protection of traffic going to devices 8

9 Operational Principles Scanning both in and outbound directions Copies of all messages can be recorded and forwarded Data analytics over messages for threat analysis, revenue assurance, etc. Corrective actions returned to the respective NetNumber Signaling Firewall DSC! STP Analysis Dia FW SS7 FW Diameter Record SS7 9

10 Signaling Firewall on TITAN Central Control, Distributed Logic, Multi-Protocol Comprehensive firewall functions Distributed execution, geo-dispersed Operational consistency across firewalls Seamless support: COTS, NFV TITAN Master HSS EIR IN-SCP HLR firewall firewall PCRF DSC AAA STP Packet Core O(F)CS Diameter LTE & WiFi firewall IWF firewall SS7/C7 for CS & PS CS/PLMN EPC, Non-3GPP

11 Conclusions Billions of IoT devices has potential to be a signaling burden Signaling and security are actually related Addressed with new signaling architecture Virtualizes applications New signaling firewall into single platform Central manage local process No need to wait for 5G to start supporting IoT Platform can support IoT in 3G and 4G networks today 11
