    Abstract: PROBLEM TO BE SOLVED: To enable network control suitable to the state of a communication network by obtaining network constitution elements to accelerate control over communication network, etc., from the result obtained by making use of messages for exchanging prescribed transfer characteristics of a communication line between the communication terminal device and information server device above the network layer and reporting control information. SOLUTION: A communication line measurement part 23 of the communication terminal device 1 sends an SYN segment of TCP to the information server device 2, which sends an SYN-ACK segment back to the communication terminal device 1 in response. The communication terminal device 1 having received it measures the response time(RTT) from the transmission of the SYN by the communication line measurement part 23 to the reception of the SYN-ACK segment. A monitor part 24 switches the operation of an application program 21 according to an estimated value of the band width between ends derived on the basis of the RTT and packet size.

    Abstract: PROBLEM TO BE SOLVED: To prevent lowering of throughput in a network by controlling intervals of acknowledgement of transmission and reception (ACK) to be transmitted to received data when transmission/reception of data is performed between a terminal and other terminals. SOLUTION: Data reception quantity is received by a received data quantity calculating part 12 and average received data quantity is newly calculated by using the data reception quantity and average received data quantity regarding period during which the ACKs are transmitted at the same intervals stored in a data reception quantity storage table 14 at a control part 11 of a client 1. The average received data quantity (1) is compared with the average received data quantity (2) at transmission intervals one stage narrower than the transmission intervals of the ACKs with the average received data quantity in the data reception quantity storage table 14 by the control part 11. When difference between the average data reception quantity (1) and (2) exceeds a certain threshold, an instruction to set the transmission interval as the one to transmit one ACK when 4380 bytes re received is transmitted to an ACK generating part 13.

    Abstract: PROBLEM TO BE SOLVED: To enhance usabiliby of a transmission line by providing an information working means to work information transmitted from an information storing means and a means to transmit the information worked by the information working means to a radio terminal with a radio base station. SOLUTION: A control means 3a checks whether or not local information to be transmitted to an information table stored in an information table storing means 3d and local information storing means 3e exists when the radio base station 3 receives a signal from a radio terminal 5. When the local information exists, the control means 3a draws contents information from a storing means 3g. When no local information exists, the control means 3a transmits a transmission request signal of the contents information requested from the terminal 5 to a database 2 and obtains the contents information. In this way, the means 3a obtains the contents information to be transmitted to the terminal 5 and also instruct an editing means 3f to edit and work the contents information based on the contents requested from the terminal 5 if necessary.

    Abstract: PROBLEM TO BE SOLVED: To perform delivery confirmation with respect to a BC frame and an MC frame in a radio communication equipment system for performing radio LAN communication. SOLUTION: For example, a STA 101 which wants to transmit ACK frame transmission to a BCMC data frame transmits an ADDBCMC request frame (a) to an AP 100. Then, the AP 100 which has received the ADDBCMC request frame (a) transmits an ADDBCMC response frame (b) to the STA 101. Thus, it is possible for the STA 101 to establish the ACK frame transmission sequence to the BCMC data frame. Afterwards, the STA 101 performs ACK frame transmission (e) to a BCMC data frame (d) from the stage of the reception of a Beacon frame (c) from the AP 100. COPYRIGHT: (C)2008,JPO&INPIT
