<p><P>PROBLEM TO BE SOLVED: To prevent the degradation of throughput due to invalid retransmission request and transmission of retransmission data, relating to a radio mobile unit and a retransmission request control method. <P>SOLUTION: The data transmitted from a server and divided into packets by a mobile communication network for transmission is reconstructed to be original TCP transmission data by a radio link control layer terminal part 12. A TCP data terminal part 13 transmits the reconstructed transmission data to a client 3. A response data transmitted from the client 3 is terminated at the TCP data terminal part 13, and is output to the radio link control layer terminal part 12. A TCP sequence number processing part 14 reads a transmission sequence number and a response sequence number of data passing through the TCP data terminal part 13. It suspends transmission of the data of the response sequence number if a difference is 1 or less, but discards the suspended data of the response sequence number without transmission if such response sequence number as larger than the response sequence number arrives within a predetermined time period. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
