A base station includes, in an aspect, a first reception unit, a first transmission unit, and a second transmission unit. The first reception unit receives information related to a communication processing state of another base station from the other base station. The first transmission unit transmits duplication of data to be transmitted to a terminal device to the other base station. The second transmission unit transmits the data to the terminal device by using radio communication. Furthermore, the first transmission unit transmits, after the transmission of the data performed by the second transmission unit has been completed, in accordance with the information related to the communication processing state of the other base station, a transmission completion notification that indicates that the transmission of the data has been completed to the other base station.

Base station, terminal device, and communication system

A base station includes a first processing unit and a second processing unit that processes a wireless signal. The first processing unit includes a third processing unit that processes a control signal and a fourth processing unit that processes user data. The third processing unit shares, with the fourth processing unit, a second terminal identifier used in user-data processing performed in the second processing unit and the fourth processing unit.

Base station, terminal, and wireless communication system

A base station device has a transmitter and a receiver. The transmitter transmits reporting information including information of divided resources, information of connection modes used when connecting to the divided resources, and information for identifying services associated with the divided resources. Here, the divided resources are obtained by dividing resources in association with services provided via a core network. The receiver receives, from a terminal that has received the reporting information, a connection request that specifies a certain connection mode to be used for connection.

Base station device, terminal device, and communication system for dividing resources to establish connection

A relay station relays communications between a plurality of home base stations and a switching station via communication interfaces. The relay station sets up a switching station side communication interface for each base station group. The switching station side communication interface is a part of a communication interface used by each home base station belonging to the base station group to communicate with the switching station, where the part is between the relay station and the switching station. The base station group includes the home base stations identified by home base station identifiers, each of which has a first data length, having a common upper segment. The upper segment has a second data length shorter than the first data length and being located sequentially from an uppermost position. The second data length is the same as a data length of a macro base station identifier.

Relay station, control method, and communication system

A gateway apparatus including a first inter-device interface configured to communicate with a monitoring apparatus; a second inter-device interface configured to communicate with a plurality of base station apparatuses that are subordinate; and a processor configured to generate second configuration information by a protocol conversion of converting first configuration information to a format compatible with the second inter-device interface, when the first configuration information is received from the monitoring apparatus through the first inter-device interface, the processor further configured to transmit the generated second configuration information to the plurality of base station apparatuses through the second inter-device interface.

Gateway apparatus and communications system

A small-scale base station includes a digital signal processor configured to generate subframes of a given number, based on first information unique to the small-scale base station and by providing a portion of the subframes as blank frames into which no information is inserted, such that positions where the blank frames are provided at the subframes form a pattern unique to the small-scale base station; and a central processing unit configured to use the generated subframes and to control data communication with a terminal.

Small-scale base station, communication system, and communication method

A base station apparatus that divides a message into a data of a transmittable size to a terminal apparatus, and transmits the divided data to subordinate all the terminal apparatuses by broadcast, the base station apparatus including: a radio utilization rate calculation unit configured to calculate a radio utilization rate indicating a rate of a time for transmission of one of the message with respect to a transmission period of each the message in case of transmitting the message repetitively, based on a number of repetition times of each the divided data and a transmission period of each the divided data; and a transmission decision unit configured to determine a transmission schedule of the data based on the radio utilization rate.

Base station apparatus and radio access system

A mobile terminal transmits a first message to a hybrid cell base station, the first message indicating the presence of the mobile terminal trying to establish a connection, the first message containing information unique to the mobile terminal. The hybrid cell base station receives the first message, and transmits a first response message in response to the first message to the mobile terminal.

Radio communication system, mobile terminal, base station, and storage unit for mobile terminal

A portable terminal device that controls execution, pausing, and termination of programs, including: a program execution section that makes an executing program become suspended, which is pausing if the executing program is an unmanaged program, or is terminating and storing restore information for restoration into a storage section if the executing program is a managed program and a program management section that makes the program execution section terminate the executing program upon receiving a request to terminate the executing program, wherein if there are the executing program and a suspended program that is being suspended by the program execution section and has an unmanaged program when the program execution section terminates the executing program, the program management section terminates the unmanaged program and reads restore information corresponding to a predetermined managed program that has been preset and makes the program execution section execute the predetermined managed program.
