Abstract:
A method for admitting a new connection to a base station based on measured quantities in a wireless communications network, said network having a base station and a plurality of remote hosts between which uplink and downlink packets flow, the method comprising steps, in combination, of:measuring at said base station an uplink Frame Error Rate, an average uplink bit rate, a burstiness factor of uplink traffic, and an uplink packet loss rate for each of said remote hosts; measuring at each of said remote hosts a downlink Frame Error Rate, an average downlink bit rate, a burstiness factor of the downlink traffic from the base station, and a downlink packet loss rate; sending said downlink Frame Error Rate from each of said remote hosts to said base station; computing at said base station an equivalent bandwidth for each remote host based on average and peak bit rates of said remote host, said burstiness factor of the traffic, and said packet loss rate of each remote host; computing at said base station an equivalent number of allowable connections based on the total equivalent bandwidth for all of said remote hosts; determining at said base station whether Quality of Service of all already admitted connections can be maintained even when said new connection is admitted; and admitting said new connection only if said Quality of Service of said already admitted connections can be maintained or if at least one of said already admitted connections can be disconnected and replaced by said new connection without loss of said Quality of Service to all others of said already admitted connections.
