Mobile device and operation method thereof

Abstract

A mobile device and an operation method thereof are provided. The method includes removing a Subscriber Identity Module (SIM) card, previously inserted into the mobile device, from the mobile device, determining whether a SIM card, identical to or different from the removed SIM card, is inserted into the mobile device, and, managing base station-related information, wherein the managing of the base station-related information comprises at least one of updating the base station-related information with base station-related information newly acquired by performing a base station-related protocol procedure based on a newly inserted SIM card, according to at least one of the type and the insertion time point of the newly inserted SIM card, and maintaining base station-related information stored based on the removed SIM card. According to the embodiments of the invention, an additional bootstrapping process is not required when the mobile device user removes or inserts a SIM card from or into the mobile device. A corresponding protocol procedure is performed to support a mobile communication service according to the type or the insertion time point of the inserted SIM card. The mobile communication service-related information and the base station-related information acquired by performing the protocol procedure can be updated or maintained.
