Abstract
An electronic device is provided, which includes a removable SIM, a secure memory configured to store at least one profile, a processor configured to select at least one of the removable SIM and the secure memory, to be used for packet data transmission and reception, in response to an occurrence of a data service change event, and a communication interface configured to perform network registration through the selected at least one of the removable SIM and the secure memory and to transmit and receive packet data through the registered network.
Claims14
An electronic device comprising:
- a removable subscriber identifier module (SIM);
- an embedded SIM storing at least one profile;
- a communication interface electronically connected to the removable SIM and the embedded SIM;
- and
- a processor electronically connected to the communication interface, the processor configured to:
- select one of the removable SIM and the embedded SIM, to be used for packet data transmission and reception, in response to an occurrence of a data service change event;
- and
- control the communication interface to register the electronic device with a packet-switched (PS) network through the selected SIM and to transmit and receive packet data through the registered PS network,
- wherein the communication interface is configured to maintain a network connection of a circuit-switched (CS) network or an Internet protocol multimedia subsystem (IMS) through the removable SIM when the embedded SIM is selected;
- and
- wherein the communication interface is configured to block the network connection of the CS network or the IMS through the embedded SIM when the removable SIM is removed from the electronic device.
A method for providing a data service by an electronic device including a removable subscriber identifier module (SIM) and an embedded SIM, the method comprising:
- detecting an occurrence of a data service change event;
- selecting one of the removable SIM and the embedded SIM, to be used for packet data transmission and reception, in response to the occurrence of the data service change event;
- registering the electronic device with a packet-switched (PS) network through the selected SIM;
- transmitting and receiving the packet data through the registered PS network;
- maintaining a network connection of a circuit-switched (CS) network or an Internet protocol multimedia subsystem (IMS) through the removable SIM when the embedded SIM is selected;
- and
- blocking the network connection of the CS network or the IMS through the embedded SIM when the removable SIM is removed from the electronic device.
