The M2M Server ? the primary component of a provider?s platform ? offers service entities to third- party application providers via the M2M Application APIs, which facilitates application development and interoperability. The M2M Gateway provides hierarchical integration of M2M service entities, allowing the functionality to reside closer to the edge of the network and closer to the entities requiring the services. The M2M Gateway also enables optimization of both network signaling and data storage, by, for example, aggregating traffic from many devices.

It supports Service Entities at M2M Devices, M2M Gateways, and M2M Servers. It also supports all reference points defined by the standards. The Service Delivery Platform is integrated with Service Entity to Service Entity interaction capabilities, which, as a unique feature, enables Device-to-Device, Gateway-to-Gateway and Server-to-Server direct communications and in turn significantly improves system reliability, scalability, and overall performance. The InterDigital M2M/IoT Service Delivery Platform can be configured to support a variety of different deployments and platforms. The Service Layer can be scaled down to a limited footprint for compatibility with devices or gateways with limited processing resources. At the other end of the spectrum, the architecture supports cloud deployments of the network service layer allowing distributed processing of the service entity functions.

It provides the following advantages: ? RESTful interfaces are stateless, based on Client/Server model and provide uniform interfaces ? Clients initiate requests to servers. Servers process requests and return responses ? Requests and responses are built around the transfer of representations of resources. Resource are stored at the Server ? Each resource can have ?unique address,? ?attributes,? and ?sub-resources? ? Each resource can be manipulated by Create/Retrieve/Update/Delete (CRUD) methods as well as Subscription Figure 4: Hierarchical Resource Tree (oneM2M and ETSI M2M) Source: InterDigital Standardized M2M/IoT Service Delivery Platform | 8 1.4 3GPP MTC-IWF and M2M Cellular Inter-Working Service In Release 11, 3GPP added the MTC-IWF to the LTE Evolved Packet Core. The MTC-IWF allows an M2M Server to send ?triggers? to M2M devices. A trigger is a short message from the M2M Server to the device that instructs it to take some action, such as register with the M2M Server. InterDigital?s M2M/IoT SDP supports an MTC-IWF which provides a 3GPP Release 11 compliant Tsp interface to M2M Servers. The Tsp interface is based on the Diameter protocol and is used by M2M Servers to make trigger requests. In Release 11, triggers are transported to M2M LTE devices via SMS. InterDigital has enhanced the MTC-IWF and PDN-GW to allow the network to send triggers to M2M devices over the devices? IP bearers. This approach allows the M2M Server to trigger any application that is running on an LTE device and listening on a UDP port for its trigger. In Release 12, 3GPP created a new ?Power Saving Mode? for M2M devices. This allows M2M devices to transition into a sleep-like state where they can conserve power, thus lengthening battery life. While devices are operating in power saving mode, they do not listen to the network and cannot receive data from the M2M Server. Complications can arise if the M2M Device and M2M Server do not properly coordinate when the device should use power saving mode. For example, data packets from the M2M Server may be discarded while the M2M device sleeps; possibly leading to increased retransmissions and core network load . InterDigital has enhanced the MTC-IWF and MME to allow M2M Servers and M2M Devices to easily coordinate the use of Power Savings Mode. New commands have been added to the Tsp interface that allow the M2M Server to configure the M2M Device?s Power Savings Mode and to receive notifications when the M2M device enters and exits Power Savings Mode. InterDigital?s M2M Server includes a oneM2M compliant service that provides applications and services with an API that can be used to access the LTE Evolved Packet Core. Applications and services can use the API to request triggers, configure a device?s Power Savings Mode, subscribe to notifications about device?s state, and receive notifications about changes in the device?s state.

The M2M Server can configure policies to collect statistics for events to be used for charging or other system monitoring purposes. The M2M Server can also provide ?charging as a service? via standardized APIs to applications registered to the Server. Different events can be supported by utilizing the policies to trigger the generation of chargeable events. The M2M Server can collect statistics for its own use, or collect statistics for applications using the charging service. The M2M Server can choose to configure charging policies for nodes at the field domain, such as gateways and devices. The M2M Server can pass the generated records to the billing domain for charging and accounting operations. With a configurable charging architecture, the M2M Server can access charging records generated within 3GPP networks via the Tsp reference point. In addition, charging functions within a 3GPP network can access and leverage charging records generated within the service layer. Both offline and online charging are supported. Standardized charging functions and protocols used by 3GPP networks are supported .

This includes constrained M2M Devices and M2M Area Networks, and the M2M Gateway is a highly efficient way to manage constrained M2M Devices behind it. The DM features help operators and customers deploy massive numbers of M2M Devices and diagnose and fix problems quickly with greatly reduced management cost. Figure 7 shows the overall device management architecture within InterDigital?s M2M/IoT SDP in which various device management standards can be supported. The architecture allows for performing device management on all types of devices from the latest smartphone to sensor devices with limited resources. The platform can support a device management server residing within the SDP or externally as a remote server. In addition, the platform can support a variety of management systems, such as OMA DM, OMA LWM2M, and BBF CWMP (TR-069). A management adapter is used to translate oneM2M messages to DM messages and from DM messages to oneM2M messages. oneM2M has defined resource mappings between oneM2M resources and the underlying management system resources that offer near seamless integration between the systems. Another benefit of InterDigital?s platform is the added flexibility of the platform providing a common interface to access device management capabilities. The same application can be used to manage devices behind a gateway (e.g., in a home environment) and devices that connect to a cloud server. Devices can be managed at the network or gateway levels and management servers can exist in both levels. For example, an LWM2M Server can be hosted in both the M2M Server and the M2M Gateway to manage LWM2M devices which have cellular or WiFi only capabilities, respectively. This allows the same application to manage both types of devices at the gateway or network levels. Figure 7: Device Management Support within M2M/IoT SDP Source: InterDigital Standardized M2M/IoT Service Delivery Platform | 11 1.7 SDP Semantic Service InterDigital?s M2M/IoT SDP supports semantic services and semantic awareness, so that data flowing through or stored within the SDP is not limited to opaque information. Examples of semantic services of the SDP include the capability to affiliate semantics with resources stored within the service layer as well as the capability to perform semantic querying of these resources. Figure 8 shows the functional architectural of InterDigital?s M2M/IoT SDP semantic service. The major components are: ? Resource Repository stores all resources that are collected from the physical M2M devices and any resources that are relevant to the M2M applications, such as person, devices, etc. involved in the M2M applications. The Resource Repository also allows semantic descriptions to be associated/linked with resources. ? Ontology Processor is in charge of processing, classifying, storing and providing a discovery function of published/ generated ontologies external and internal to the SDP . ? Ontology Repository stores the ontologies. Those ontologies can be used to enable semantics for resources. ? Semantics Repository stores the annotated semantics information, which may have the option of utilizing the Resource Description Framework (RDF). Semantics annotation is a processs of representing a resource?s semantics in a concrete format, such as a binary stream. ? Rule Repository stores the rules that are used to represent new knowledge that often goes beyond the existing semantics that is associated with the resources in the Resource Repository. Rules are typically conditional statements: if-then clauses . ? Reasoner takes input from the Rule Repository and the existing resource semantics information in the Semantics Repository, and generates new resource semantics information if the conditions in the rules are satisfied. New resource semantics information is added to the Semantics Repository. ? Semantic Query Processor handles the queries from clients to search over the resource semantics information stored in the Semantics Repository and returns the results to the clients.

It supports: ? A light-weight automated service discovery procedure based on a well-known resource. This is excellent for situations where the network address of the M2M Server, Gateway, or Device to be targeted by the service discovery procedure is known in advance; ? An advanced procedure based on the definition of a new M2M Service Discovery Function (MSDF) which leverages the underlying concepts of the DNS-SD protocol to find available service entities.

The API supports customization of transport layer implementations such as CoAP and HTTP and payload formatting libraries such as XML and JSON to facilitate reuse of preferred libraries. The M2M Service layers use primitives, defined by standards, which are converted to objects ready to use in an application. The API supports all standards defined primitives as well as customization of primitives to support prototyping and value added feature sets. The size of the API can be optimized to reduce the footprint for a final product, as would be required by a constrained device.

The portal provides users with access to the following: ? Documentation ? Software Development Kits (SDKs) ? Testing & Integration Tools ? Build Tool for creating customized SDP executables ? Tutorials, FAQs, and Forums Figure 11: SDP Web Portal Home Screen Source: InterDigital Standardized M2M/IoT Service Delivery Platform | 15 The documentation available on the portal includes documents describing the M2M API, the use of InterDigital?s Virtual M2M Server, and documents describing how to use the custom testing and integration tools that are available for download on the site. A number of Software Development Kits (SDKs) are available on the site which provide the user with sample applications that are compatible with the SDP and the needed API libraries bundled with project files for the most popular development environments including Eclipse and Microsoft Visual Studio. Additionally, the sample applications and the API libraries are available in C and Java languages. These SDKs allow users to quickly download and begin running M2M/IoT applications with the SDP . InterDigital has developed a number of customized testing and integration tools that are available on the portal. These tools allow the user to gain insight into the operation of the SDP with the applications by providing visibility into the resource structure and messaging of the SDP. The most compelling feature of the portal is the Build Tool which allows users to create and download their own customized build of the SDP. In this way, it satisfies different user requirements and enables automated on-demand SDP generation and customization. It allows users to customize builds features based on: ? SDP Compliance ? Operating System ? Node Type ? Database Type ? Runtime Environment ? Deployment The build process is reflected in Figure 12 .

Please note, access to the portal requires the establishment of a Non-Disclosure Agreement (NDA) with InterDigital for access to the documents and an Evaluation Agreement (EA) for access to the complete site including the SDP executables, API libraries, and utilities. 1.11 Open Message Bus (OMB) Architecture The InterDigital IoT Service Platform is built upon the Open Message Bus (OMB) architecture. The OMB provides a flexible and scalable architecture that enables different types of services to interconnect and interoperate with one another in a seamless and generic manner. In this way, oneM2M, ETSI M2M, and third party/advanced services can interface to one another over the OMB. The architecture can be scaled based on the desired deployment so that it can support cloud based services all the way down to device based services. The OMB backbone supports a set of native services which include an OMB Database Service, an OMB Service Directory, and an OMB Administration Console. These native services provide services to those entities connecting to the OMB. All services interface to the OMB via OMB clients which provide a layer of abstraction between the services and the underlying transport.

Evolution will effectively integrate ?connectivity? and ?content? with ?context,? ?collaboration,? ?cloud,? and ?cognition.? The future Internet of Things will be a global network of interconnected objects, enabling object identification/discovery and semantic data processing via C6 capabilities consisting of ? Connectivity: connection for mobile and constrained objects; ? Content: massive data produced from things; ? Cloud: cloud service and cloud content storage; ? Context: context-aware design to improve performance; ? Collaboration: cooperative communications, inter-things, service sharing; ? Cognition: mine the knowledge from massive data and provide autonomous system adjustment for improvements. In the proposed C6-based IoT model, each C6 capability is not independent of each other rather they interact with each other to enable joint optimization. Such interactions involve various information exchange among these C6 capabilities as illustrated in Figure 14 to enable future SMART IoT system with features such as Scalability, Manageability, Adaptability, Reliability, and Trustworthiness (SMART) .

A real world use case To this point, we have been discussing the capabilities and features of the InterDigital Service Delivery Platform and how it facilitates a variety of M2M/IoT applications and vertical markets. In this section we present a use case of how Interdigital?s SDP and its advanced features can be leveraged to improve peoples lives even in their most routine activities. We will describe how the IoT and InterDigital?s SDP can be a integral part of everyday life using a visit to the local gym to workout. For purposes of this use case, we will stipulate the following: ? The user has a smartphone running InterDigital?s SDP and a compatible gym application ? The user has a smartwatch that allows monitoring of his/her vital signs (heart rate and blood pressure) and connects to an application on the users smartphone ? The gym is equipped with WiFi network allowing access to a M2M Gateway running InterDigital?s SDP which is also hosted in the gym?s network ? The gym equipment is WiFi enabled so that it can communicate with the M2M Gateway and other systems on the network The configuration of this use case is shown in Figure 16 .

Treadmill Applica?on (DA) Standardized M2M/IoT Service Delivery Platform | 20 This use case leverages a number of the features highlighted in this document as well as some additional features that are also supported by the SDP. At a high level, the use case plays out as follows: 1 . The use case starts by a user arriving at the gym with his M2M capable smart phone and smart watch 2 . Upon entering the gym, the user?s phone automatically discovers the Gym?s network and registers to use its value-added M2M services 3 . Next, the Gym?s M2M services push a list of available gym equipment to a Gym app running on the user?s phone 4 . In addition, a list of suggested apps that the user may be interested in is also pushed to the Gym app on the user?s phone 5 . From this list, the user selects an app that allows him to upload workout information to his health insurance provider in order to receive a discount on his future premiums. The app is automatically downloaded to the user?s phone 6 . 6) Next, the user selects an available treadmill using his Gym app and with a single push of a button on his smart watch, configures the treadmill with his workout preferences 7 . During his workout, the rate of vital statistics reported by his watch to the treadmill is dynamically negotiated to conserve the watch?s battery while still maintaining the minimum update rate required by the treadmill 8 . Throughout his workout the user?s heart rate is monitored and used to automatically adjust the speed of his treadmill to ensure the user has an optimal workout 9 . At the completion of his workout, the user?s workout data is uploaded to his health insurance provider so he can receive his discount To explore some of the operations in greater detail we highlight some of the key features being exploited by this use case in the follow paragraphs . Feature: Sevice Discovery and Identify Management 1) M2M Server publishes service discovery record to service discovery server 2) GW and Device (smartphone Service Capabilites (SC)) query service discovery server to discover M2M Server (i.e. its base URI) and then register to it 3) In advance, the Gym has set up a service discovery and identity provisioning server and provisions it with a pool of identifiers 4) GW publishes service discovery record to service directory in the discovery server (co-located with the GW) 5) Device queries service directory (co-located with the GW) to discover the GW and to also request an identity and credentials 6) Device registers to GW using provisioned identity 7) GW validates Device has a valid identity before allowing it to register Standardized M2M/IoT Service Delivery Platform | 21 Feature: Device Management 1) App Store Network Application (NA) uploads Apps from its store to Device Management (DM) Server (note that this is done ahead of time using a proprietary procedure/mechanism) 2) App Store NA creates containers in M2M Server to store info about it apps and also subscribes to these containers to receive app download requests 3) Gym Device Application (DA) requests download of Watch DA and/or Health Insurance DA by creating contentInstance with its contact info in M2M Server 4) App Store NA gets notification from M2M Server and retrieves contact info of phone (from contentInstance or data entry) 5) App Store NA creates a management object resource with phone?s contact info 6) M2M Server communicates a SW update to the DM Server via the web services interface 7) DM Server sends commands to DM client running on phone to install new app on phone Feature: Semantics 1) Semantic descriptions are created on M2M Server. Semantic descriptions for this use case include English and Metric descriptions for speed and weight 2) Watch configures a ?semantics? attribute in weight and speed container resources with URI linking to seman tic description on M2M Server for English units 3) Treadmill fetches semantic description from M2M Server using URI in semantics attribute and uses it to display weight and speed in English units 4) User decides to switch watch to Metric units. Watch updates semantics attribute with URI pointing to semantic descriptions on M2M Server having Metric units 5) Treadmill fetches semantic description from M2M Server using URI in semantics attribute and uses it to display weight and speed in Metric units Feature: Negotiation 1) Treadmill App creates negotiation policy in GW to define upper and lower bounds of rate of incoming heart rate updates 2) Watch App creates negotiation policy in GW to define upper and lower bounds of rate of outgoing heart rate updates 3) Watch App starts GW-based negotiation between watch and treadmill to select the rate of heart rate updates per minute 4) GW performs negotiation on behalf of watch and treadmill to compute a heart rate update request rate that is agreeable to both treadmill and watch 5) Based on watch?s battery level, watch re-negotiates The use case described above is only one example of how InterDigital?s standards based Service Delivery Platform can facilitate integration of differnet M2M/IoT devices and applications to benefit the user. These same features and capabilities can be applied to use cases including home automation, telematics, smart grid, etc. Standardized M2M/IoT Service Delivery Platform | 22 1.14 Summary and Conclusion Global standards such as oneM2M and ETSI TC M2M accelerate the development and re-use of service solutions.
