摘要： PROBLEM TO BE SOLVED: To provide a means for allowing a radio access network to control a data rate of a data source, which has an adaptive rate, related to a radio terminal.
SOLUTION: A data transmission control method includes the steps of: monitoring (S30) a communication quality at the radio access level of a communication between a radio terminal and an access point of a radio access network; and setting (S31) a congestion indication marking in a plurality of data units of a transport service, that the access point provides, if the communication quality satisfies a radio communication deterioration condition. The congestion indication marking is an explicit congestion notification included in an IP header of the data unit. As a result, when it is determined that radio communication quality is deteriorated under a given level, the access point can operate to reduce a transmission rate of data sources through a simple feedback mechanism (congestion indication marking).

摘要： PROBLEM TO BE SOLVED: To provide an encoding method improving acoustic feeling quality of a multi-channel audio signal.
SOLUTION: The method includes a step of generating a first output signal x'
mono to be an encoding parameter expressing a main signal x
mono and a step of generating a second output signal p
side to be an encoding parameter expressing a sub signal x
side , wherein the main signal x
mono is a first linear combination of at least signals 16A, 16B of first and second channels. The sub signal x
side is a second linear combination of at least the signals 16A, 16B of the first and second channels in the encoding frame. The step of generating the second output signal includes a step of scaling the sub signal x
side according to an isoenergetic curve of the main signal x
mono .
