In current approaches to M2M architectures, no interworking application programming interfaces (API's) are exposed to the service layers that are in the local network. Thus, a service layer might not able to make various requests including, for example, that devices be triggered, that the service layer receive notifications when devices are connected to the network, and that the service layer receive notifications when devices are no longer connected to the network. Described herein is a small cell architecture that provides an interworking interface to applications and service layers that reside in the local small cell network. For example, a small cell or eNB may send a notification, for example to a Local Security Capability Exposure Function (L-SCEF) or a core network function, when a UE attaches to or disconnects from a local network.
