    Abstract: The various embodiments herein provide a method and system for operating a multi-subscriber identity module (SIM) mobile device. The method includes identifying a common suitable public land mobile network (PLMN) cell between a first radio frequency (RF) unit and a second RF unit of the mobile device. The first RF unit and the second RF unit of the mobile device are currently camped on different PLMN cells. Further, the method includes enforcing at least one of the first RF unit and the second RF unit to camp on said common suitable PLMN cell and disabling one of the first RF unit and the second RF unit when at least one of the first RF unit and the second RF unit camps on the common suitable PLMN cell.

    Abstract: A method and system for operating a multi-Subscriber Identity Module (SIM) mobile device are provided. The method includes determining whether at least one Registered Public Land Mobile Network (RPLMN) among a first RPLMN of a first SIM and a second RPLMN of a second SIM of the multi-SIM mobile device is unavailable to the multi-SIM mobile device when the multi-SIM mobile device triggers a Public Land Mobile Network (PLMN) search, identifying a common PLMN, from a first PLMN set associated with the first SIM and a second PLMN set associated with the second SIM, in response to determining that the at least one RPLMN among the first RPLMN and the second RPLMN is unavailable, and camping on the common PLMN by the first SIM and the second SIM after acquiring camping information of the common PLMN.

    Abstract: A method of optimizing connection mode procedures for a dual subscriber identity module (SIM) mobile communication device is provided. The method includes receiving, by a base station, a paging message for a first SIM in an idle mode from a core network; determining, by the base station, if a radio resource control (RRC) connection linked with the first SIM is available or not; triggering, by the base station, a second paging type message for the first SIM with a normal cause through the RRC connection linked with the first SIM if the RRC connection of the first SIM is available; determining, by the base station, if a RRC connection linked with a second SIM is available or not if the RRC connection of the first SIM is not available; triggering, by the base station, a second paging type message for the first SIM with a mapped new cause through the RRC connection linked with the second SIM if the second SIM is available; and triggering, by the base station, a first paging type message with a temporary identity and a cause received in the paging message from the core network through a paging channel if the RRC connection linked with the second SIM is not available.
