Patent ID: 7477602

Claim:
A method of optimizing download rate to a mobile host from an application server in a telecommunications network, said method comprising: providing an information gateway between said mobile host and said application server capable of adjusting said download rate; measuring a throughput rate using the following equation R(τ)=M/Δt, wherein R(τ) is the measured throughput rate, Δt is a measurement time interval, τ be a current measurement time and M is a number of messages that arrive during the time interval; calculating an estimated throughput rate for an application flow using the following equation {circumflex over (R)}(τ)=α(τ)R(τ)+(1-α(τ))E[R τ-Δt ], wherein the estimated value E[R τ-Δt ] is a weighted average of the current measured value and the average of the last K-1 measured values where K is the index of the current measured value, and weight value α(τ) is an average fractional difference between consecutive measurements points; calculating the difference between said measured throughput rate and said estimated throughput rate and if said difference is less than a predetermined sensitivity parameter, then increasing said download rate through said information gateway by a predetermined incremental amount.
