Abstract
Provided is a method to operate a subscriber identification module connected to a communication equipment configured to operate in a cellular network and communicatively coupled with a remote server. The method includes receiving from the communication equipment an information element indicating a time range relating to a suspend time of the communication equipment, receiving from the remote server a target access time information element indicating an expected time for an access request from the subscriber identification module to the remote server, and determining a suspension time period considering the suspend time range. The method includes providing to the communication equipment the suspension time period, and in case after resuming from the suspension instructed by the communication equipment the accumulated duration of at least one successive time period derived from the suspension time period exceeds the target access time, sending a polling message.
