QoS (QUALITY OF SERVICE) CONTROL SYSTEM, QoS CONTROL METHOD, AND QoS CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To ensure execution of a plurality of processing steps of the same contents in all terminals without exhausting surplus CPU processing capabilities in low-performance terminals and surplus NW bands in terminals within a narrow-band NW.;SOLUTION: Each of terminals 1200₁ to 1200_n measures a terminal performance, a NW performance. terminal resources, and NW resources when starting communication. An arbiter 100 preliminarily stores the amount of terminal resources and NW resources, which is predicted to be necessary for execution of AP start processing and AP operation change processing in each terminal performing communication. When AP start processing or AP operation change processing will be performed in each terminal performing communication, the arbiter 100 confirms that overload and a lack of NW bands don't occur in terminals having the lowest terminal performance and the lowest NW performance, on the basis of measurement results of respective terminals and the amounts of terminal resources and NE resources predicted to be necessary for execution of AP start processing or AP operation change processing, and then instructs execution of AP start processing or AP operation change processing to the terminal.;COPYRIGHT: (C)2008,JPO&INPIT
