20130122892 | MOBILE COMMUNICATION METHOD AND RELAY NODE - A mobile communication method according to the present invention includes a step in which, when a relay node RN, which is subordinate to a radio base station DeNB and is in an “RRC_CONNECTED state”, received an “RRC connection release message” from the radio base station DeNB, the relay node RN is transitioned to an “RRC_IDLE state” after transmitting an “RRC connection release message” to a mobile station UE, which is subordinate to the relay node RN and is in the “RRC_CONNECTED state”, and a predetermined time T2 elapses. | 05-16-2013 |
20130124677 | BROADCAST SUPPLEMENTAL DATA TRANSMISSION DEVICE AND BROADCAST SUPPLEMENTAL DATA TRANSMISSION METHOD, AND BROADCAST SYSTEM - Provided is a broadcast supplemental data transmission device, a broadcast supplemental data transmission method, and a broadcast system that can reduce the traffic of a communication network as much as possible at the time of supplementing missing data in broadcasted content data. When “GET HTTP/1.1 If Unmodified Since Time Information”, which is a request for retransmission of missing data containing time information, is received from a receiving device, an HTTP response module determines whether there is rebroadcast of contents containing missing data based on the time information contained in the request for retransmission. When it is determined by the HTTP response module that there is rebroadcast, “412 Precondition Failed”, which is one of error notifications, is transmitted as a response to the receiving device, and the transmission of the contents through a communication network is not performed. | 05-16-2013 |
20130170428 | MOBILE COMMUNICATION METHOD, RADIO BASE STATION, AND RELAY NODE - A mobile communication method according to the present invention includes a step of transmitting, by a radio base station DeNB, “RA Response” to a mobile station UE within a “RA Response window” for the mobile station UE when “RA Preamble” is received from the mobile station UE, a step of transmitting, by a relay node RN, a signal to the mobile station UE in a subframe other than an MBSFN subframe, and a step of transmitting, by the radio base station DeNB, “RA Response” to the relay node RN in an MBSFN subframe of a “RA Response window” for the relay node RN when “RA Preamble” is received from the relay node RN. | 07-04-2013 |
20130201897 | BASE STATION, RELAY STATION AND METHOD IN MOBILE COMMUNICATION SYSTEM - A base station generates first setting information commonly used for establishing a logical path for communication with a user apparatus and for establishing a logical path for communication with a relay station, and second setting information used only for establishing the logical path for communication with the relay station, and transmits a second RRC message including the second setting information to the relay station after transmitting a first RRC message including the first setting information to the relay station. The first setting information includes information indicating a priority of a radio bearer in the logical path, information indicating usage of resources in SPS, information indicating resources of SRS, configuration information in a MAC sublayer, and information on change of a security encryption key in handover, and the second setting information includes at least system information and MBSFN information. | 08-08-2013 |
20130203342 | RELAY STATION FOR RELAYING COMMUNICATION BETWEEN USER APPARATUS AND BASE STATION, AND RELAY METHOD - A relay station includes a signal generation unit configured to generate a signal in the relay station and a receiving unit configured to receive a signal from a first communication station. The relay station further includes a signal generating node identifying unit configured to identify whether a signal to be transmitted to a second communication station is a received signal received from the first communication station or a generated signal generated by the signal generation unit. The relay station further includes a signal transmission unit configured to transmit both or one of the received signal and the generated signal associated with a radio bearer to the second communication station. | 08-08-2013 |
20130208652 | RELAY STATION, BASE STATION, RADIO COMMUNICATION SYSTEM, AND METHOD - A relay station for relaying a radio signal between a mobile station and a base station includes a relay station information generating unit configured to generate relay station information used by the base station to select a switching center to be connected to the relay station. The relay station also includes a message generating unit configured to generate a message including the relay station information generated by the relay station information generating unit, and a transmitting unit configured to transmit the message generated by the message generating unit to the base station. | 08-15-2013 |
20130208653 | RELAY NODE AND RECONNECTION METHOD - A relay node of a communication system includes a communication unit that initiates a session by executing an initial connection procedure for retrieving a cell list indicating one or more donor base station candidates from a maintenance node after establishment of an initial communication link among the relay node, a base station, and a switching center, and for establishing a communication link to a donor base station in the cell list and a switching center connected to the donor base station; a storing unit that stores the cell list; and a reconnection control unit that selects, when a radio link with the donor base station is lost, a donor base station satisfying a predetermined criterion in the cell list, and that causes the communication unit to establish a communication link to the selected donor base station and a switching center connected to the selected donor base station. | 08-15-2013 |
20140312361 | SEMICONDUCTOR ELEMENT, SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING SEMICONDUCTOR ELEMENT - The semiconductor element has an electrode including: a Ni-inclusion metal layer containing nickel formed on a side of at least one surface of the semiconductor-element constituting part; a Ni-barrier metal layer formed outwardly on a side of the Ni-inclusion metal layer opposite to the side toward the semiconductor-element constituting part; and a surface metal layer outwardly formed on a side of the Ni-barrier metal layer opposite to the side toward the semiconductor-element constituting part, to be connected to the metal nanoparticles sintered layer; wherein the Ni-barrier metal layer contains a metal for suppressing diffusion of nickel toward the surface metal layer. | 10-23-2014 |
