20100048248 | COMMUNICATION TERMINAL AND EXCHANGE RATE DETERMINING METHOD THEREOF - A communication terminal and exchange rate determining method thereof are disclosed. The method includes determining exchange rate information according to first country information, received from Subscriber Identity Module (SIM) information of a SIM card, and second country information, received from a System Information Block (SIB) broadcast from an affiliated base station, determining exchange rate information according to the first country information and the second country information, selecting a first amount, corresponding to a first monetary unit of the first country information, determining a second amount, corresponding to a second monetary unit of a the second country information, from the selected first amount using the exchange rate information, and displaying the second amount. | 02-25-2010 |
20110077031 | APPARATUS AND METHOD FOR REDUCING POWER CONSUMPTION IN MULTI-MODE PORTABLE TERMINAL - An apparatus and method for reducing power consumption in a multi-mode portable terminal are provided. The apparatus includes a Subscriber Identity Module (SIM) management unit and a control unit. The SIM management unit is configured to determine whether there are multiple SIM cards of the same serving cell in a portable terminal supporting a plurality of RF modules and a plurality of SIM cards. The control unit is configured to activate only one RF module corresponding to the SIM cards of the same serving cell when receiving information of the SIM cards of the same serving cell from the SIM management unit. | 03-31-2011 |
20110256876 | APPARATUS AND METHOD FOR REDUCING RESOURCE CONSUMPTION IN MOBILE TERMINAL - An apparatus and a method for reducing unnecessary resource consumption in a mobile terminal are provided. The method includes determining, when a first timer expires, whether the periodic location update procedure can be performed, when the periodic location update procedure cannot be performed, starting a second timer, and, when the second timer expires, performing an International Mobile Subscriber Identity (IMSI) attach procedure. | 10-20-2011 |
20110264941 | APPARATUS AND METHOD FOR REDUCING POWER CONSUMPTION CAUSED BY COMMUNICATION BETWEEN PROCESSORS IN PORTABLE TERMINAL - An apparatus and method for reducing power consumption in a portable terminal are provided. The apparatus includes a display unit for displaying at least one indicator that indicates status information measured by a slave processor, a master processor for controlling one of ON and OFF of the display unit and for providing image data to the display unit, and the slave processor for transmitting to the master processor indicator update information for updating the at least one indicator, wherein transmission to the master processor of the indicator update information is discontinued if the status of the display unit is OFF. | 10-27-2011 |
20120064883 | METHOD AND APPARATUS FOR EPLMN LIST MANAGEMENT IN MOBILE TERMINAL - An apparatus and method for Equivalent Public Land Mobile Network (EPLMN) list management in a mobile terminal are provided. The method includes receiving a message from a network after storing an EPLMN list having at least one PLMN entry, determining whether an EPLMN list is present in the received message, and performing EPLMN list management by maintaining, when an EPLMN list is not present in the received message, the stored EPLMN list. As a result, the mobile terminal may retain an accurate EPLMN list and efficiently perform cell selection/reselection. | 03-15-2012 |
20120076076 | METHOD AND APPARATUS FOR CONNECTING TO NETWORK FROM MOBILE TERMINAL - A method for connecting to a network from a mobile terminal capable of forming a high-performance radio channel in a Universal Mobile Telecommunication System (UMTS), and an apparatus implementing the same are provided. The method includes transmitting a Radio Resource Control (RRC) connection request message indicating a first release version to the network, receiving an RRC connection setup message indicating a second release version from the network, comparing the first and second release versions, determining whether there is a third release version lower than the first release version and higher than the second release version when the second release version differs from the first, and, if there is the third release version lower than the first release version and higher than the second release version, transmitting an RRC connection request message indicating the third release version to the network when the second release version differs from the first release version. | 03-29-2012 |
20120077494 | MOBILE COMMUNICATION DEVICE HAVING PLURALITY OF SUBSCRIBER IDENTIFICATION MODULE (SIM) CARDS AND METHOD FOR SELECTING PUBLIC LAND MOBILE NETWORK (PLMN) IN THE DEVICE - A mobile communication device including Subscriber Identification Module (SIM) cards, and various methods for searching for a Public Land Mobile Network (PLMN) for each SIM card, are provided. In one method, the device separately starts Home PLMN (HPLMN) timers according to corresponding HPLMN timer values stored respectively in the SIM cards, performs a PLMN search for one of the SIM cards at an expiry of a corresponding one of the HPLMN timers, and updates a PLMN list with one or more PLMNs found during the PLMN search. The device then determines, for all of the SIM cards, whether the PLMN list contains any PLMN with a higher priority than a currently registered PLMN. Also, the device performs, for any SIM card of the SIM cards in which there is any PLMN with the higher priority than the currently registered PLMN, a location registration in the PLMN with the higher priority. | 03-29-2012 |
20140099935 | METHOD AND SYSTEM FOR UPDATE OF NETWORK-RELATED INFORMATION, AND ELECTRONIC DEVICE SUPPORTING THE SAME - A system and method for network-related information is provided. In a method for updating network-related information, an electronic device determines whether the network-related information is received from a currently accessed service network, and accesses another service network if the network-related information is not received, and receives the network-related information from the newly accessed service network. | 04-10-2014 |
20150089268 | APPARATUS AND METHOD FOR REDUCING POWER CONSUMPTION CAUSED BY COMMUNICATION BETWEEN PROCESSORS IN PORTABLE TERMINAL - An apparatus and method for reducing power consumption in a portable terminal are provided. The apparatus includes a display unit for displaying at least one indicator that indicates status information measured by a slave processor, a master processor for controlling one of ON and OFF of the display unit and for providing image data to the display unit, and the slave processor for transmitting to the master processor indicator update information for updating the at least one indicator, wherein transmission to the master processor of the indicator update information is discontinued if the status of the display unit is OFF. | 03-26-2015 |
