摘要： A method and apparatus are described for accessing services affiliated with a service provider. A first discovery procedure may be performed to discover at least one service provider, and a bootstrap procedure may be performed with at least one discovered service provider. A second discovery procedure may then be performed to determine available service capability layers (SCLs) supported by the at least one discovered service provider. The first discovery procedure may include transmitting a service provider discovery request including information for querying a record database to determine matching service provider discovery records, and receiving a service provider discovery response including a service discovery function record list that matches queries in the service provider discovery request. At least one service provider from the service discovery function record list may be selected to bootstrap with. Various versions of the second discovery procedure are described.

摘要： A method and apparatus for supporting machine-to-machine (M2M) caching at a service capability layer are disclosed. A service capability layer of an M2M entity provides functions that are shared by the M2M applications and expose functionalities to the M2M applications through a set of open interfaces. The service capability layer may be configured to cache resources in a resource structure of the service capability layer. The service capability layer caching can provide complete cached resource discovery, and provide more intelligent and robust security mechanism to authenticate the clients, and subscription to the cached resource becomes flexible and feasible. M2M service may be virtualized in a cloud. An M2M cache manager may maintain a record of resources cached in a plurality of M2M servers and coordinate the M2M servers in caching the resources. The M2M cache manager may provide mapping between a virtualized cached resource and a real cached resource.
