Analysis of the possibility of passive assessment of the bit rate in WCDMA systems


I.V. Hanin, S.S. Shigurov

The possibility of passive assessment of bit-rate Internet connection in cellular networks WCDMA. The authors propose an alternative method for determining the hours of maximum and minimum load on the network, as well as the indirect determination of the bit rate of the Internet connection on the basis of experimental data on the received signal strength (DPDCH) and the signal / noise ratio provided to the input of the user terminal. To estimate the bit-rate Internet connection is necessary to once in a given time by monitoring the speed of file transfer to a remote server, set the maximum possible speed for a given location, and then to carry out passive monitoring of the rate with a valuation of the results obtained by the maximum value. Provides an example of the practical implementation of this method.
