System and method for receiving call in wireless terminal
First Claim
1. A system for receiving a call, the system comprising:
- a wireless terminal having a single Radio Frequency (RF) device and at least a first Subscriber Identity Module (SIM) card and a second Subscriber Identity Module (SIM) card; and
a Base Station (BS) related to the first SIM card for informing the wireless terminal of an incoming call request for the second SIM card in response to a paging request for the second SIM card that is received from a BS related to the second SIM card, while the wireless terminal is performing a call through the first SIM card, wherein;
if both of the calls end, the wireless terminal transmits, to the BS related to the second SIM card, an incoming call forwarding registration release request message for requesting a release of an incoming call forwarding registration.

7. A method of receiving a call in a wireless terminal including a single Radio Frequency (RF) device and a first Subscriber Identity Module (SIM) card and a second SIM card, the method comprising:
-
if an incoming call request for the second SIM card is received to by a Base Station (BS) related to the second SIM card while the wireless terminal is performing a call through the first SIM card, requesting, by the BS related to the second SIM card, a Base Station (BS) related to the first SIM card for paging to the second SIM card; if the paging request for the second SIM card is received by the BS related to the first SIM card, informing, by the BS related to the first SIM card, the wireless terminal, of the incoming call request for the second SIM card while the wireless terminal is performing the call through the first SIM card; if both of the call ends in the wireless terminal, transmitting, by the wireless terminal, an incoming call forwarding registration release request message to the BS related to the second SIM card; and if the incoming call forwarding registration release request message is received from the wireless terminal, releasing, by the BS related to the second SIM card, a registration of the incoming call forwarding to the second SIM card. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A terminal for processing a call, the terminal comprising:
-
a single Radio Frequency (RF) device for receiving an incoming call; a first Subscriber Identity Module (SIM) card and a second SIM card; and a controller configured to perform a call with a first terminal in communication with a first base station rebated to the first SIM card through the first SIM card and transmitting an incoming call forwarding pre-registration message to a second base station related to the second SIM card; and if an incoming call request for the second SIM card is received from the first base station while the terminal is performing the call with the first terminal through first SIM card, inform a user of the terminal of the incoming call request for the second SIM card, wherein the controller transmits an incoming call forwarding registration release request message to the second base station if both the calls ends. - View Dependent Claims (15)
