  • Patent number: 7953408
    Abstract: A sender of a message can transmit a message to an unspecified user merely by specifying a condition of space without specifying a recipient of the message, using an information processing terminal transmitting a message not with a user address to specify a user but with an area address (a condition of space) to specify an area within an electric wave reachable range of a radio base station; and a server converting the area address to a user address which specifies a PHS terminal currently located in the area represented by said area address and transmitting the message with a converted address to a switching equipment.

  • Patent number: 7353500
    Abstract: In a method for testing a program, repeated measurement on branches that are frequently taken is prevented, thereby avoiding unnecessary overhead. An information processing device includes a coverage measurement control program for determining whether the number of times an instruction of a measurement target program has been executed due to execution of the measurement target program is equal to or larger than the maximum allowable number of measurements set for the instruction; and a coverage measurement program for incrementing a value in a field for the instruction by one to indicate the number of times the instruction has been executed, the coverage measurement program being called if the number of times the instruction has been executed is smaller than the maximum allowable number of measurements.

  • Patent number: 7295512
    Abstract: A system for use with communications according to TCP, or a similar protocol, includes a sender host, one or more routers, and a destination host. Each router includes means for generating acknowledgement packets and translating addresses associated with data packets. When a data packet is received by a router, an acknowledgement packet is returned with a source address corresponding to the router and a destination address corresponding to the sender host. The sender host perceives the acknowledgement packet as having been sent by the destination host. As the acknowledgment packet is sent by the router, and not the destination packet is sent by the router, and not the destination host, this system allows acknowledgment packets to be received on a shorter timescale, reducing the effects of a link delay. Although the route between the sender host and the destination host is divided into multiple connections, the hosts perceive a single, conventional connection.

  • Patent number: 7216166
    Abstract: The present invention provides a technique suitable for configuration management of a network for which the number of logical network layers can be set. A network management apparatus 10 receives an address definition information file defining logical hierarchical structure of an IPv6 network 20, from an operator through a definition information reception unit 103. A configuration analysis unit 104 generates management tables defining hierarchical relationships of logical networks, based on the address definition information file and IP addresses collected respectively by an information collection unit 102 from network elements belonging to the IPv6 network 20, and registers the management tables into a management DB unit 101.
