  • Simplified short message service (SMS) procedure for communication with internet of things devices
    Patent number: 10484844
    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.
