Further, the method comprises calculating, by the MME [202], a requested retransmission time (RRT) for each of the buffered at least one (TDR). The method thereafter comprises transmitting, from the MME [202] to the SCEF [204], at least one mobile terminal data answer (TDA) corresponding to each of the buffered at least one TDR for management of response time to the at least one NB-IoT device [102], wherein the at least one TDA comprises of at least the calculated RRT for each of the corresponding buffered at least one TDR.
The present invention relates to a system and a method for managing communication between at least one NB-IoT device [102] and an application server [108]. The method comprises continuously receiving, at a mobility management unit [104], one or more data request from the application server [108] for the at least one NB-IoT device [102]. The mobility management unit [104] transmits a paging request to the at least one NB-IoT device [102] and dynamically monitors a response to the paging request from the at least one NB-IoT device [102]. The mobility management unit [104] continuously buffers the one or more data request based on the dynamic monitoring, and transmits, the one or more buffered data request based on one of an expiry of the paging request and the dynamic monitoring for managing communication between at least one NB-IoT device [102] and the application server [108].
