9. A method for operating a transceiver at a mobile terminal containing two subscriber identification module (SIM) interfaces, the transceiver configured to provide communication with a first mobile communication network and a second mobile communication network identified by subscription information respectively provided through the two SIM interfaces, the method comprising:

controlling the transceiver to receive paging information from the first mobile communication network for a first period based on periodic occurrences of paging information associated with the first mobile communication network;

receiving a first paging indicator from the first mobile communication network;

scheduling, upon decoding a negative paging indicator from the first mobile communication network, immediate control of the transceiver to receive paging information from the second mobile communication network for a second period based on periodic occurrences of paging information associated with the second mobile communication network; and

receiving a paging indicator or a paging message from the second mobile communication network,

wherein the receiving a first paging indicator from the first mobile communication network and the receiving a paging indicator or a paging message from the second mobile communication network allows the mobile terminal to maintain concurrent paging reception with the first mobile communication network and the second mobile communication network.
