    摘要： A communication path between base stations is switched so as to prevent data transmitted from a mobile station undergoing handover from being lost. A base station (12) which is a handover destination includes an RTP communication control unit (34) for receiving an RTP packet corresponding to a radio signal transmitted from a first mobile station from a base station which is a handover source and transferring the received RTP packet to another base station which performs a radio communication, with a second mobile station which makes a call connection with the first mobile station with a handover start of the first mobile station, a voice comparison unit (40) for determining the identity of voice information included in the received RTP packet and voice information included in a radio signal received from the first mobile station, and a transmit data switching unit (42) for switching the RTP packet transmitted by the RTP communication control unit (34) to the another base station from the RTP packet received from the handover source base station to the RTP packet corresponding to the radio signal received from the first mobile station at a timing when the identity of the voice information is confirmed.

    摘要： In a case where, although a radio base station (eNB 1-1) has established an SRS transmission frequency band, a serving radio terminal (UE 2-1) has transmitted, to the radio base station (eNB 1-1), an SRS by use of only a frequency band that is a part of the SRS transmission frequency band, the radio base station (eNB 1-1) allocates a downstream resource block the frequency band of which is included in the SRS transmission frequency band and further the frequency band of which is identical with the frequency band of the SRS received at the latest; then establishes, for the downstream resource block, a transmission weight based on the SRS received at the latest; and then uses the downstream resource block to transmit a radio signal.

    摘要： A gas sensor includes an internal space, diffusion control part, pumping cell, and measuring cell. The diffusion control part communicates with the internal space and has a slit-like shape with a smaller thickness than that of the internal space. The pumping cell pumps out oxygen from the internal space when voltage is applied between a first electrode fowled on a surface of the internal space and a second electrode formed outside the internal space. The measuring cell measures a current flowing between a third and fourth electrodes when a voltage is applied between the third and fourth electrodes. The third electrode is formed in the diffusion control part, and can reduce an oxide gas component in a predetermined gas component to which a predetermined diffusion resistance has been applied by the diffusion control part. The fourth electrode is formed in a part different from the diffusion control part.
