Abstract
One or more protocols between a control plane entity (e.g., a mobility management entity (MME)) and its peer nodes (e.g., mobile switching center (MSC) and/or short message service center (SMSC)) are enhanced to improve short messaging services for Internet of things (IoT) devices. Oftentimes, IoT devices enter an extended sleep mode during which they cannot be reached by the control plane entity. In one aspect, the control plane entity can determine a wait period based on information, such as, but not limited to, device context data, mapping tables, policy data, commercial traffic data, latency data, device delay tolerance, sleep mode timer values, etc. The wait period can be provided to the peer nodes, which can utilize the wait period to control one or more message retry mechanisms based on IoT device behaviors resulting in an improvement of overall IoT service behaviors and a delivery of superior IoT customer experience.
