Patent ID: 8483201

Claim:
A method of controlling a terminal enabling channel capacity estimation in a High-Speed Downlink Packet Access (HSDPA) network, comprising: receiving, by the terminal, two data packets of the same size that are consecutively transmitted via a channel without causing time latency; measuring a received time difference between the two packets; dividing the length of any one packet of the two packets by the time difference to calculate a channel capacity value; calculating an average channel capacity value based on a plurality of channel capacity values; and estimating the channel capacity based on a plurality of average channel capacity values, wherein a server transmits ‘N’ data packets to the terminal so that the plurality of channel capacity values are calculated from the ‘N’ packets, and the average channel capacity value is determined from the plurality of channel capacity values, wherein the ‘N’ packets comprises a plurality of two consecutively transmitted packets of the same size.
