1. A dual SIM mobile terminal, comprising:
- a dual SIM configured to support different services, the dual SIM including a primary SIM and a secondary SIM;
a first and a second wireless communication unit; and
a controller connected to the dual SIM and the first and second wireless communication units to support double standby and single talk,wherein the controller performs network synchronization using neighboring cell information of each SIM network if a service requested by the user through the switched SIM is performed and then a service request for the SIM is received again.

Abstract
Disclosed herein is a dual SIM terminal and an operating method thereof for supporting dual standby and single talk using a single baseband. The dual SIM mobile terminal may include a controller which is a single chipset, a dual SIM, and two radio frequency (RF) units, thereby having an effect capable of providing a service at the same level as a dual SIM using two mobile terminals even with one mobile terminal. Furthermore, dual SIM switching is performed according to a state of the network, a pricing system, and a user'"'"'s setting, thereby providing the user'"'"'s desired service.

19. A method of operating a dual SIM mobile terminal, the method comprising:
-
detecting an active state of the dual SIM, the dual SIM including a primary SIM and a secondary SIM; automatically performing SIM switching according to a network state of the SIM and a user'"'"'s service request if the initial user'"'"'s service is requested in an active state of the dual SIM; performing a service requested by the user through the switched SIM; and performing network synchronization using neighboring cell information of each SIM network if a service requested by the user through the switched SIM is performed and then a service request for the SIM is received again. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
