Disclosed is an apparatus and method for estimating a channel capacity of an end-to-end terminal. The channel capacity estimating method of the end-to-end terminal includes calculating an average value of channel capacities for each size of data packets, the data packets varying in size, measuring an actual channel capacity with respect to the data packets, and deriving a linear model of a channel capacity based on the size of the data packets using the average value of the channel capacities and the actual channel capacity.

Apparatus and method for estimating channel capacity of end-to-end terminal

A server and a terminal enabling channel capacity estimation in a High-Speed Downlink Packet Access (HSDPA) network and a method of controlling the server and the terminal are provided. More particularly, when transmitting data between both terminals in an HSDPA network, a server end may transmit a packet pair of the same size and a client end may measure a time difference between the packet pair and thereby proceed filtering. Through this, it is possible to estimate the channel capacity. Therefore, it is possible to prevent data transmission from exceeding the channel capacity in the HSDPA to thereby prevent a packet loss and to effectively use a channel.
