Abstract:
A control method comprises: transmitting, by a first management apparatus included in a first network allocated with a first frequency band, to a second network allocated with a second frequency band, an allocation request signal for requesting allocation of a part of the second frequency band to the first network, the signal being generated on the basis of a usage state of the first frequency band, determining, by a second management apparatus included in the second network, on the basis of a usage state of the second frequency band, a bandwidth to be allocated to the first network out of the second frequency band and an allocated frequency band corresponding to the bandwidth; managing the allocated frequency band as unavailable; transmitting, an allocation request response signal including information indicating the allocated frequency band, to the first network; and managing the allocated frequency band as available in the first network.
Abstract:
A communication control method comprises: transmitting, by a communication apparatus, a Device to Device (D2D) resource notification to a user terminal. The D2D resource notification includes information indicating a predetermined D2D radio resource available in a D2D proximity service and information indicating a condition not allowing for use of the predetermined D2D radio resource.
Abstract:
A communication control method according to a present embodiment comprises: a step of transmitting, by a first base station, to a third base station that is a neighboring base station of the first base station, a first resource message relating to a first D2D resource used for the D2D proximity service in the first base station. The first resource message includes information on the first D2D resource and a second D2D resource used for the D2D proximity service in a second base station that is a neighboring base station of the first base station.
Abstract:
A communication control method according to the present embodiment is used in a mobile communication system having an OFF target base station that intends to set an OFF target cell to OFF that is a cell of the OFF target base station, and an extension target base station that is to perform a cell extension for compensating the OFF target cell. The communication control method comprises: a step of transmitting, by the OFF target base station, list information to the extension target base station before the cell extension is performed, the list information being maintained in the OFF target base station and being used when the OFF target cell is managed; and an management step of managing, by the extension target base station, an extension target cell whose coverage is extended, on a basis of the list information.
Abstract:
A communication control method comprises: a setting step of setting, by an eNB 200-1 which manages a first cell, radio resources consisting of a portion of resource blocks of the plurality of resource blocks as an ePDCCH region for transmitting a downlink control signal in the first cell, in at least one of the plurality of subframes; a transmitting step of transmitting, by the eNB 200-1, ePDCCH information indicating the ePDCCH region to an eNB 200-2 which manages a second cell; and a receiving step of receiving, by the eNB 200-2, the ePDCCH information.
Abstract:
A communication control method according to an embodiment comprises: receiving, by a first network apparatus, first information from a first user terminal, the first network apparatus configured to belong to a first Public Land Mobile Network (PLMN); and notifying, the first network apparatus, the first user terminal of second information. The first information includes a first identifier included in a discovery signal which the first user terminal has directly received from a second user terminal. The second information includes information corresponding to the first identifier. The communication control method further comprises determining, by the first network apparatus, in response to receiving the first information, whether the first identifier is a second identifier allocated in the first PLMN. The first network apparatus notifies the first user terminal of the second information in response to determining that the first identifier is the second identifier.
Abstract:
A mobile communication system which supports D2D communication that is direct inter-terminal radio communication, comprises: a user terminal that transmits and receives discovery signals for a discovery process of a communication target terminal of the D2D communication; and a base station that transmits discovery resource information indicating radio resources to be used for transmitting and receiving the discovery signals. The user terminal transmits and receives the discovery signals when the discovery resource information is received from the base station, by using the radio resource indicated by the received discovery resource information.
Abstract:
A communication control method according to the present embodiment comprises the steps of: relaying, by a gateway apparatus in a cellular network, user data from an external network to a user terminal connecting to the cellular network; switching an accommodation target of traffic of the user terminal from the cellular network to another network not managed by an operator managing the cellular network; and relaying, by the gateway apparatus, on a basis of a location of the user terminal in the another network, the user data to the user terminal, via the another network.
Abstract:
An eNB 200 transmits a broadcast control signal commonly applied to all UEs 100 in a cell of the eNB 200 and a dedicated control signal dedicatedly applied to a UE 100 in the cell. A UE 100 receives the broadcast control signal and the dedicated control signal. The broadcast control signal includes a plurality of D2D resource information. Each of the plurality of D2D resource information indicates a radio resource available for the D2D communication. The dedicated control signal includes instruction information for instructing a use of a radio resource indicated by specific D2D resource information, out of the plurality of D2D resource information.
Abstract:
A communication control method includes: a step A of receiving, by UE 100-1 in a coverage of the mobile communication system, broadcast information transmitted from eNB 200; a step B of transferring, by the UE 100-1, the broadcast information to UE 100-2 outside the coverage of the mobile communication system; and a step C of receiving, by the UE 100-2, the broadcast information transferred from the UE 100-1.
