Claim 11:
12. A Subscriber identification module connected to a communication equipment, which is configured to operate in a cellular network, wherein the subscriber identification module is communicatively coupled with a remote server,
wherein the subscriber identification module is configured to:
receive from the communication equipment an information element indicating a time range relating to a suspend time of the communication equipment, hereinafter the suspend time range,
receive 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, hereinafter the target access time,
determining a suspension time period considering the suspend time range,
