Abstract
A method of managing access to a plurality of Packet Switched (PS) networks of a wireless communication apparatus including a plurality of Subscriber Identity Modules (SIMs) includes obtaining first information indicating data service-related preferences for the plurality of SIMs, selecting at least one SIM necessary for accessing each of the plurality of PS networks from among the plurality of SIMs, based on the first information and second information indicating a wireless network capable of being provided by an operator corresponding to each of the plurality of SIMs, and accessing each of the plurality of PS networks by using the selected at least one SIM.
Claims20
A method of operating a wireless communication device including first and second subscriber identity modules (SIMs) to access a packet switched (PS) network including an Internet packet data network and an Internet Protocol multimedia subsystem (IMS) packet data network, the method comprising:
- configuring the wireless communication device to utilize the first SIM to access the Internet packet data network based on a preference of a user among the first and second SIMs;
- and
- configuring the wireless communication device to utilize the first SIM to access the Internet Protocol multimedia subsystem (IMS) packet data network for performing first type call, when a first operator corresponding to the first SIM does not support a circuit switched (CS) network for performing second type call.
A wireless communication device comprising:
- first and second subscriber identity modules (SIMs) configured to utilized to access a packet switched (PS) network including an Internet packet data network and an Internet Protocol multimedia subsystem (IMS) packet data network;
- and
- a processor configured to,
- determine to utilize the first SIM to access the PS network based on a preference of a user,
- check at least one of whether a first operator corresponding to the first SIM supports a circuit switched (CS) network for performing first type call and whether a second operator corresponding to the second SIM supports the CS network;
- and
- determine whether to utilize the first SIM to access the IMS packet data network for second type call based on check result.
