  • Patent number: 8588068
    Abstract: In a situation where a communication line is busy in a TCP communication, or in a situation where TCP data is continuously received, divided transmission of TCP-ACK is suppressed. A communication terminal includes a transmission standby frequency estimation unit 103 that estimates a transmission standby frequency of the TCP-ACK according to the situation of the communication line and a TCP-ACK generation control unit 106 that controls the generation frequency of the TCP-ACK on the basis of the estimated transmission standby frequency estimate information. The TCP-ACK generation control unit 106 adjusts the generation frequency of the TCP-ACK so as to reduce the generation frequency of the TCP-ACK if the transmission standby frequency is higher than a predetermined value.

  • Patent number: 8582543
    Abstract: A wireless communication device is quickly connectable to an access point of a destination service area without wasting power when the wireless communication device moves from a service area to a different one. When a state change detector of the wireless communication device detects that the received radio field intensity of the radio wave from the connected access point lowers to a threshold or less, a service area information acquirer acquires information on the service area where the wireless communication device is present and information on a neighboring service area. A profile information acquirer acquires profile information corresponding to the service area information. A priority order setter sets the order of priority to the acquired profile information in such a way that the access point of a neighboring service area neighboring to the service area formed by the connected access point is precedingly connected.

  • Publication number: 20130170420
    Abstract: Provided is a wireless communication device capable of setting an appropriate transmission power flexibly in accordance with the surrounding environment when returning to a normal power mode from a low power mode. In the wireless communication device (100), during operation in an awake mode a reception quality recording unit (120) records a first reception quality which is a reception signal quality from an AP to be connected, and a second reception quality which is a reception signal quality from an AP not to be connected. A variation determination unit (130) determines a difference between the first reception quality and the second reception quality. An initial value setting unit (150) sets an initial value of the transmission power of an awake notification signal transmitted when starting operation in the awake mode next time on the basis of the difference between the first reception quality and the second reception quality.
