Abstract
A method for monitoring LWMM IoT device state includes, in an SCEF, providing an interface for receiving subscription requests from IoT application servers or service capability servers for monitoring LWMM IoT device state, the method further includes maintaining, in the SCEF, a database of identifiers of IoT devices that utilize LWMM protocols, receiving, via the interface and from an SCS or AS, a first monitoring event request for subscribing to receive state information regarding an IoT device, and performing a lookup in the database using an IoT device identifier extracted from the first monitoring event request and identifying the first monitoring event request as being associated with an LWMM IoT device. The method further includes communicating with the LWMM IoT device using LWMM constrained application protocol (CoAP) messaging to subscribe to and receive state information from the LWMM IoT device and communicating the state information to the SCS or AS.
