20090055556External storage medium adapter - An external storage medium adapter for establishing a connection between a computer and an external storage medium, said external storage medium adapter comprising:02-26-2009
20110092236MOBILE COMMUNICATION METHOD, MOBILE STATION AND RADIO BASE STATION - The mobile communication method has a step wherein a mobile station (UE) generates first verification information using a fast key, a first parameter, and an algorithm for ‘Integrity Protection,’ a step wherein the mobile station (UE) generates second verification information by excising a specific bit in the first verification information, and a step wherein, when a wireless link obstruction is detected in an RRC connection, the mobile station (UE) performs cell selection processing and transmits an RRC-PDU for an RRC reconnection request, wherein the second verification information is set, over a shared control channel to the wireless base state that manages the selected cell.04-21-2011
20110105078PAGING SIGNAL TRANSMISSION METHOD AND MOBILE STATION FOR THE SAME - A paging signal transmitting method includes a step of allowing each of mobile stations (UE) to receive security data from a network node (05-05-2011
20110105124MOBILE COMMUNICATION METHOD AND MOBILE STATION - The present invention relates to a mobile communication method in which a mobile station performs a handover from a handover source radio base station to a handover target radio base station. The mobile communication method includes the steps of: (A) acquiring, at the handover target radio base station, from the handover source radio base station or a switching center, a key for calculating a first key for generating a certain key used in a communication between the handover target radio base station and the mobile station; and (B) acquiring, at the handover target radio base station, from the switching center, a second key for calculating a first key for generating a certain key used in a communication between a next handover target radio base station and the mobile station.05-05-2011
20110105156NOTIFICATION SIGNAL TRANSMISSION METHOD AND MOBILE STATION FOR THE SAME - A method for transmitting a notification signal comprises a step in which each of a plurality of mobile stations (UE) compares first security information which each of the mobile stations manages with second security information included in a received first notification signal to thereby verify the validity of the first notification signal and a step in which each of the mobile stations (UE) performs the output corresponding to the first notification signal in the case of successfully verifying the validity of the first notification signal.05-05-2011
20110111787METHOD FOR REPORTING MULTI-ADDRESS INFORMATION, MOBILE STATION AND AUTHENTICATION ORGANIZATION SYSTEM - A method for reporting multi-address information comprises a step wherein each of mobile stations (UE) obtains the positional information relating to the mobile stations (UE) and manages information relating to the obtained positional information, a step for reporting multi-address information provided with an electronic signature to each of the mobile stations (UE), a step wherein each of the mobile stations (UE) verifies the multi-address information by use of the electronic signature provided to the received multi-address information, a step wherein each of the mobile stations (UE), when the verifying is successful, compares positional information contained in the multi-address information with the positional information being managed, and a step wherein each of the mobile stations (UE) performs processing in response to the multi-address information on the basis of the result of comparing.05-12-2011
20110122843MOBILE COMMUNICATION METHOD - In a mobile communication method according to the present invention includes the steps of: transmitting, from a handover source radio base station to a switching center, a handover request including an NCC, a PCI and a K05-26-2011
20110124358MOBILE COMMUNICATION METHOD - A mobile communication method according to the present invention communicates between a mobile station (UE) and a radio base station (eNB) by using a certain key. The method includes the step of: (A) acquiring, at a radio base station managing a re-establishment target cell for the mobile station (UE), a first key (K05-26-2011
20110128937MOBILE COMMUNICATION METHOD, RADIO BASE STATION, AND MOBILE STATION - A mobile communication method according to the present invention includes steps of: generating, at a HO-source radio base station, an intermediate key (K06-02-2011
20110159873MOBILE COMMUNICATION METHOD - In a mobile communication method according to the present invention includes the steps of: transmitting, from a handover source radio base station to a switching center, a handover request including an NCC, a PCI and a K06-30-2011
