A broadcast manager identifies a time interval that encompasses paging windows for a plurality of user equipment. The plurality of user equipment operate according to a plurality of discontinuous reception cycles that include sleep intervals separated by the paging windows. The broadcast manager generates messages for wireless transmission to the plurality of user equipment in corresponding paging windows during the time interval. The messages include information indicating a transmission time at which the plurality of user equipment are to receive broadcast or multicast data. The transmission time is subsequent to the time interval.

Broadcasting or multicasting to user equipment that use extended idle mode discontinuous reception

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.

Simplified short message service (SMS) procedure for communication with internet of things devices

A method, in one example, comprising the steps of receiving a tracking area identifier indicating a tracking area where a user equipment (UE) is located, and updating a current tracking area of the UE based on whether the tracking area identifier indicates that the UE is currently in a previously visited tracking area.
