A mobile communication system includes a mobile station, a base station that communicates wirelessly with the mobile station, a gateway apparatus that connects the base station to a core network, and a core network apparatus that is arranged in the core network. The base station includes a control unit that includes, in a message, information indicating that the mobile station has originated a call as an emergency call, and a transmission unit that transmits the message to the core network apparatus. In addition, the core network apparatus includes a reception unit that receives the message that was transmitted from the base station.

In order to change control over a user equipment within a femtocell in accordance with a change in camping of the user equipment, a communication system includes a femto base station (10) that provides a femtocell includes notification destination setting means (20) for setting, in the femto base station (10), a notification destination to be notified of a change in camping of a user equipment (30) on the femtocell. The femto base station (10) notifies the set notification destination of the change in camping of the user equipment (30), upon detection of the change in camping.
摘要:
A communication system, (a base station apparatus, a data transmission method, and a program) in which unnecessary signalings do not occur in a large quantity as a result of the execution of a SON function, includes an eNB and an eNB that performs data transmission/reception with the eNB, in which the eNB includes a signal transmission/reception unit that transmits information to the eNB, the information being used to determine whether or not autonomous setting information should be transmitted from the eNB to the eNB.

A mobile communication system includes terminals and a plurality of base stations that use scrambling codes to perform radio communication with the terminals. Each of the plurality of base stations transmits to neighboring base stations information of the range of scrambling codes for uplink that is reserved in its own station, and when determining the range of scrambling codes for uplink to be reserved in its own station, receives from neighboring base stations information of the ranges of scrambling codes for uplink reserved in the neighboring base stations.

Each of belt layers of a pneumatic radial tire includes a plurality of single steel wires with an identical wire diameter extending linearly in an identical direction in alignment with each other and embedded in rubber. Each of the wires is provided with axial torsion. On the outer surface of a tread portion, circumferential grooves extend in the circumferential direction of the tire. The wire diameters of the single steel wires are 0.28 mm to 0.38 mm. An average of intervals of the single steel wires is not less than 0.10 mm. The tire has an out-of-plane bending stiffness of not less than 6000N·mm2 per inch of length of the tread portion in the circumferential direction when a force application point is located at the circumferential groove. The implanted density E (wires/50 mm) of the single steel wires satisfies E≧1869×d2−1838×d+493, where d is the wire diameter.
摘要:
A steel cord having a 1×2 construction formed by twisting two wire strands together is used as a reinforcing layer of a pneumatic tire. The steel cord has a carbon content of from 0.60 to 0.75%, a strength in the tire of from 2,900 to 3,500 MPa, and a twisting angle of from 1.5 to 3.0°. Therefore, productivity can be enhanced while fatigue resistance of the steel cord used in the reinforcing layer is maintained. Additionally, fatigue resistance of the steel cord is further enhanced due to the average value of the forming factor of the steel cord of this tire being set to from 95 to 105% and the standard deviation σ being set to from 5 to 20%. As a result, tire durability can be enhanced.

An ultrasonic testing equipment includes a linear array ultrasonic probe in which a plurality of transducers are arranged in a direction orthogonal to the rolling direction of a test object and a signal processing unit. The signal processing unit executes following (1) to (6). (1) Generating an aperture synthetic image of testing signals of each section of the test object. (2) Generating a maximum value distribution of testing signals in the arrangement direction of transducers. (3) Calculating the width of a defect in each section based on the maximum value distribution. (4) Generating a maximum value distribution of the testing signals in the rolling direction based on the maximum value distribution of a plurality of sections of the test object. (5) Calculating the length of the defect based on the maximum value distribution of the testing signals in the rolling direction. (6) Calculating the area of the defect based on the calculated defect length and the calculated defect width of each section.
