Abstract:
A mobile network entity configured to upon reception of a TFR message forwarding a SM towards a UE in extended idle mode DRX, including a SM-Delivery-Timer/Start-Time indicating the time used in the SM gateway SMSC to supervise the receipt of the TFR message, keep the SM for a specified time if the UE is expected to become reachable before the expiration of the timer, and page the UE. If the UE responds to this paging during this specified time, the mobile network entity configured to deliver the SM to the UE, and if the UE does not respond to this paging during this specified time, or if the UE is not expected to respond within this time, send towards a SM gateway SMSC a delivery failure and set a flag to record that the UE is currently not reachable.
