2 Introduction We will be conducting two independent demonstrations: M2M Gateway and M2M Core Network (referred to here as the M2M Server) M2M WPAN These demonstrations highlight the work that InterDigital is doing to prototype an M2M System based on the current ETSI M2M standard Requirements and design were largely based on Version of the Functional Architecture Document (TS ) They are building blocks for an end to end prototype that we are developing that will include devices that represent D devices connected to an ETSI compliant M2M Gateway and M2M Server 2

4 M2M Gateway and M2M Server Demonstration 4

5 Demo High Level Description Demonstrate a variety of procedures between an ETSI compliant M2M Gateway and ETSI M2M Server Utilize a 3GPP connection between the Gateway and the Server Utilize two separate demo applications, one on the Gateway and one on the Server Use demo application on the Gateway (also serving as the Gateway Application (GA)) to: Provide control of the demo procedures from the gateway side and issue operations towards the Network Application (NA) such as read, write, and execute Provide a dummy application that will respond to operations initiated from the NA such as read, write, and execute An example could be a thermostat application that will provide temperature readings to the NA and allow the NA to set the temperature of the thermostat, etc Use the demo application on the Server (also serving as the NA) to: Provide control of the demo procedures from the network side and issue operations towards the GA such as read, write, and execute Provide a dummy application that will respond to operations initiated from the GA such as read, write, and execute 5

6 Use Cases Currently Supported Device Registration (mid) Device Application Registration (mid & dia) Network Application Registration (mia) M2M DA Resource Creation (GW or Server) M2M DA Resource Deletion (GW or Server) M2M NA Resource Creation (GW or Server) M2M NA Resource Deletion (GW or Server) M2M NA to M2M Device Read (Online) M2M NA to M2M Device Write (Online) M2M NA to M2M Device Execute (Online) M2M NA to M2M Device Read (Offline) M2M NA to M2M Device Write (Offline) M2M NA to M2M Device Execute (Offline) M2M DA to M2M NA Read M2M DA to M2M NA Write M2M DA to M2M NA Execute Notes: - In this demo the gateway is the only device therefore gateway and device are equivalent (as are GA and DA) - Additional use case support is being added in the next phase of development 6

7 M2M Gateway Laptop (Debian Linux) Platform Description Sierra Wireless Compass 888 USB Modem data card for backhaul connection M2M Server Laptop (Debian Linux) Picochip Femto Cell with Continuous Computing Corporation (CCPU) Femto Access Point (FAP) Software Core Network Emulation (CNE) Laptop with CCPU CNE SW (Redhat Linux) Ethernet Router/Switch 7

8 Demo Network Configuration Note: For this demo the Gateway Application will run on the M2M Gateway laptop and the Network Application will run on the M2M Server laptop 8

9 Gateway Manager + Service Capabilities CoAP Support Gateway (Demo) Application 3G Connectivity: M2M Gateway Software Overview Driver for 3G Data Card is built into Debian Linux Utilize PPP protocol and connection scripts to establish the packet data connection 9

10 M2M Gateway Processes Note: Highlighted entities are currently supported as separate processes on the Linux platform 10

11 M2M Server Software Overview Server Service Capabilities Support for Gi MCN interface CoAP Support Network (Demo) Application 11

12 M2M Server Processes Note: Highlighted entities are currently supported as separate processes on the Linux platform 12

14 M2M Secure Session Ka?? UMTS WiFi Ka1 SC mid M2M Server KNa1 xgc M2M In/Out Box In/Out Box Device/GW Ka1 KNa1 mia M2M Network App CoAp HTTP SIP Notes: 1. Application Keys for the M2M Device/GW are per session and are not common with the M2M Network Application keys. This implies that per communication the M2M Server will cipher/decipher all messages. 2. Investigate how a shared key can be used for direct communication. 14

15 M2M WPAN Demonstration 15

16 This demonstration focuses on IP-based M2M Area Networks based on IETF standards including CoAP and 6LoWPAN M2M Area Networks is referred to as WPAN in this presentation A WPAN consists of a WPAN Coordinator and WPAN Devices Introduction The latest CoAP protocol was implemented (draft-ietf-corecoap-01) It serves as a building block for an end to end M2M prototype 16

17 Demo High Level Description Purpose Demonstrate full IP-based protocol stack running over low-power sensors devices, i.e. WPAN Devices Demonstrate two independent IP-based IEEE WPAN networks on different IEEE channels Use Case Currently Supported Utilize two separate demo applications, one on WPAN Devices and one on the WPAN Coordinator Demo application on the Laptop CoAP Client Issue CoAP request message (GET) to read the temperature sensor value at a WPAN Device Demo application on WPAN Devices CoAP Server Wait for CoAP request message from the Laptop, relayed via the WPAN Coordinator Read the temperature sensor which is integrated with each WPAN Device Pack the temperature value in a CoAP response message and send it back to the Laptop via the WPAN Coordinator Notes: - Additional use cases (CoAP Methods) support are being added in the next phase of development 17

18 The Laptop (Debian Linux) Implement Demo application CoAP Client Implement CoAP protocol Implement 6LoWPAN protocol stack (BLIP) Two USB ports WPAN Coordinator (TinyOS) Platform Description A Crossbow Micaz node connecting to the Laptop via USB port Run IPBaseStation application as a relaying point between WPAN Devices and the Laptop WPAN Devices (TinyOS) Crossbow Micaz nodes with a temperature sensor integrated Implement Demo application CoAP Server Implement CoAP protocol Implement 6LoWPAN protocol stack (BLIP) 18
