    摘要： Some underlying networks such as Low-Power Wide-Area Networks (LPWAN) have limited communication bandwidth and strict requirements on maximum message size. These requirements may pose a challenge for data or resource exchange between two service layer (SL) entities, for example, because resource representations to be exchanged may have too large a size to be supported by the underlying networks. In some cases, traditional data compression algorithms can be used to alleviate this problem to some degree, but it is recognized herein that there are associated computation costs due to compression and decompression that may not be affordable for constrained IoT devices. Various embodiments described herein address this problem, among others by defining a Resource Representation Common Part (RRCP) and storing it at the service layer. In some cases, the RRCP is not transmitted between SL entities, thereby reducing SL message sizes to cater to the constraints of underlying networks.

    摘要： The concept of a service layer message template is introduced, which may be a request template or a response template. Message templates may be created and stored at the service layer. Each message template may contain a set of request or response parameters and their values. Once in place, an application can send a request to the service layer that does not include the request parameters contained in the message template (i.e. request template); instead, a message template identifier may be sent. Since request parameters are included in the message template and stored at the service layer, communication overhead between the service layer and the application (or another service layer) may be reduced.

    摘要： A service layer entity (e.g., application entity, common service entity in oneM2M, also referred to as registree entity) may register to another service layer entity (e.g., common service entity in oneM2M, also referred to as a registrar entity) and proactively request to gain access to the local services hosted by the registrar entity. A registrar entity may accept a registree entity's registration request but only grant access of its partial services to the registree entity. If a registree entity does not need to proactively request the services within its registration request message, the registrar entity decides what services may be needed by the registree entity and grants access of those services to the registree entity.

    摘要： A Service Capability Exposure Function can be added to the UE (U-SCEF). The U-SCEF may be part of the UE's operating system (OS) and expose API's to applications that allow these applications to schedule data plane communications such as periodic sensor measurements or a firmware download. The U-SCEF communicates with an EPC Interworking Service that resides in the mobile network operator's (S)Gi-LAN. The EPC Interworking Service serves as an interface between the U-SCEF and the service capabilities that are exposed by the MNO via the SCEF. The U-SCEF may provide the EPC Interworking Service with information about the UE's anticipated communication schedule and mobility status. The EPC Interworking Service uses the services that are exposed by the SCEF to determine the optimal times for the UE to communicate, an optimal mobility management configuration, etc. The EPC Interworking Service negotiates a communication schedule with the EPC (SCEF) on behalf of the UE (U-SCEF) and provide the U-SCEF with a communication policy or mobility management policy to match the needs of the UE and the mobile network.
