Patent ID: 10555202

Abstract:
A method for monitoring IoT device state includes, in an SCEF implemented using at least one processor. The method includes providing a common interface for receiving subscription requests from IoT ASs and SCSs for monitoring state of IoT devices of plural different generation networks. The method further includes maintaining, in the SCEF, a database of identifiers of IoT devices of a first-generation network, providing, in the SCEF, an interface to a subscriber data repository node of the first-generation network, and receiving, via the common interface, a subscription request for subscribing to receive updates in state information for an IoT device. The method further includes performing a lookup in the database and identifying the subscription request as being associated with an IoT device registered in the first-generation network and transmitting a message to the subscriber data repository node of the first-generation network for receiving state information regarding the IoT device.
