MULTI-SIM DEVICE AND OPERATION METHOD THEREOF
First Claim
1. A multi-subscriber identification module (SIM) device comprising:
- a first SIM configured to use a first service of a first network;
a second SIM configured to use a second service of a second network;
a first radio frequency (RF) resource configured to support use of a non-limited channel configuration according to a radio resource control (RRC) protocol;
a second RF resource configured to support use of a limited channel configuration according to the RRC protocol; and
a baseband processor configured to selectively assign the first RF resource and the second RF resource to the first SIM and the second SIM, based on information regarding the first network and the second network.

Abstract
A multi-subscriber identification module (SIM) device includes: a first SIM configured to use a service of a first network; a second SIM configured to use a service of a second network; a first RF resource configured to support use of non-limited channel configuration according to a radio resource control (RRC) protocol; a second RF resource configured to support use of limited channel configuration according to the RRC protocol; and a baseband processor configured to selectively assign any one of the first RF resource and the second RF resource to the first SIM and the second SIM, based on information regarding the first network and the second network.

15. A multi-subscriber identification module (SIM) device comprising:
-
a plurality of SIMs; a plurality of radio frequency (RF) resources assigned to the plurality of SIMs, a first portion of the plurality of RF resources supporting use of a non-limited channel configuration and a second portion of the plurality of RF resources supporting use of a limited channel configuration according to a radio resource control (RRC) protocol; and a baseband processor configured to, in response to RF resource use request intervals of at least two target SIMs among the plurality of SIMs overlapping each other, control the plurality of RF resources to support the use of the non-limited channel configuration for one of the at least two target SIMs and to support the use of the limited channel configuration for the other of the at least two target SIMs, based on information regarding networks respectively corresponding to the at least two target SIMs. - View Dependent Claims (16, 18)

19. A method of operating a multi-subscriber identification module (SIM) device comprising a first SIM and a second SIM, the method comprising:
-
generating, by using the first SIM, a radio frequency (RF) resource request; determining whether it is possible to set a dual radio (DR) mode in which use of a non-limited channel configuration and use of a limited channel configuration are simultaneously supported, based on first information regarding a first network corresponding to the first SIM and second information regarding a second network corresponding to the second SIM; and selectively assigning a first RF resource supporting the use of the non-limited channel configuration and a second RF resource supporting the use of the limited channel configuration to the first SIM and the second SIM, based on a result of the determining. - View Dependent Claims (20, 21, 22, 24)
