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 |
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 |
20130288687 | RELAY APPARATUS, RADIO COMMUNICATION SYSTEM, AND TRANSMISSION CONTROL METHOD - A relay station includes a reception section that receives a first radio frame sent from a base station, and a transmission section that sends a second radio frame that includes a downstream data signal included in the received first radio frame, to a mobile station located in a cell of the relay station. When it is determined that a first identifier of a handover-destination cell, included in a first radio frame, matches a second identifier of the cell of the relay station, included in the second radio frame, and that the transmission timing of the first identifier matches the transmission timing of the second identifier, a time shift section of the relay station shifts the transmission timing of the second radio frame sent from the transmission section so as to make the transmission timing of the first identifier different from the transmission timing of the second identifier. | 10-31-2013 |
20140094145 | MOBILE COMMUNICATION METHOD AND MOBILE MANAGEMENT NODE - In an attach process executed as a relay node RN, the wasteful use of a resource is avoided. A mobile communication method according to the present invention includes a step of transmitting, by a radio base station DeNB, “(S1) Initial UE message” indicating the attach process executed as the relay node RN to a mobile management node MME in response to “Attach Request (RN)” received from the relay node RN having a secure channel established between the relay node RN and USIM-RN, a step of starting, by the mobile management node MME, “EPS-AKA” between the relay node RN and the USIM-RN in response to the “(S1) Initial UE message”, and a step of failing in the “EPS-AKA” when it is determined that the USIM-RN cannot be used for the attach process executed as the relay node RN. | 04-03-2014 |
20140120922 | RADIO COMMUNICATION SYSTEM AND NETWORK - A first base station forms a first cell and communicates by radio with a user apparatus in a first frequency band. A second base station forms a second cell and communicates by radio with the user apparatus in a second frequency band different from the first frequency band. A gateway apparatus serves as a connection point with an external network. Logical paths used for the user apparatus are established respectively through the first base station and the second base station. A communication control section controls the logical paths and radio communication. The user apparatus sends and receives a user signal to and from the external network by using both a first logical path and a second logical path at the same time. | 05-01-2014 |
20140376435 | RADIO COMMUNICATION SYSTEM, USER EQUIPMENT, BASE STATION, SERVER DEVICE AND COMMUNICATION CONTROL METHOD - A user equipment is capable of executing plural applications in parallel. The user equipment obtains, for each application, packet statistics information relating to packets that each of the plural applications transceives, for reporting to a base station. The base station, based on the packet statistics information received from the user equipment, calculates a state transition parameter for use in controlling the state transition of the user equipment and the base station. The base station executes state transition control based on the calculated state transition parameter. | 12-25-2014 |
