Abstract: An agent is configured to receive queries from an application server in a communication network. The queries are directed to one or more devices in the communication network. The agent selects a communication path for a device from a plurality of communication paths from the application server to the device. The communication path is selected based on a data size that is to be sent to the device as part of the query, a number of devices that are to receive the query, or a combination thereof. The agent transmits the query via the selected communication path. The communication path can be selected based on one or more of a time criticality of the query, a subscription class of a user of the device, a category of a type of the device, an operator-defined influence factor, network conditions along the communication path, a broadcast flag in the query, or a combination thereof.

Abstract: A service capability exposure function (SCEF) receives a short message service (SMS) message associated with a user equipment. The SCEF identifies a destination for the SMS message on the basis of a mapping between a unique identifier of the user equipment and an external identifier of the user equipment. The SCEF transmits the SMS message towards the destination. Receiving the SMS message and transmitting the SMS message are performed without establishing a packet data network (PDN) session for conveying the SMS message. A mobility management entity (MME) receives the SMS message and identifies the destination for the SMS message on the basis of a unique identifier of the user equipment included in the SMS message. The MME transmits the SMS message towards the destination.
