Abstract
A detector is used to sample of set of power measurements of a receive signal. The receive signal may comprise one or more signals from remote users as well as interference. A variance of the set of power measurements is also determined. The variance is compared to an overload threshold value. If the variance exceeds the overload threshold value, for some period of time, the system is declared to be operating at a potentially unstable point. In this state, future connection originations are denied.
Claims14
An apparatus in a communication system, comprising:
- a load detection unit to receive a set of power measurements of signals received from system users and interference, the load detection unit to calculate an average and a variance of the set of power measurements and to calculate a predicted loading of the system based on the average and variance of the set of power measurements;
- and
- a controller to control a number of system users based on the predicted loading and a predetermined threshold, the controller to determine whether to accept or deny connection requests depending on whether the predicted loading exceeds the predetermined threshold.
A method for controlling loading in a base station, comprising:
- determining a set of power measurements of signals received at the base station;
- calculating an average and a variance of the set of power measurements;
- calculating a predicted loading level of the base station based on the average and the variance of the set of power measurements;
- and
- determining whether to accept or deny connection requests based on the predicted loading level and a predetermined threshold.
A machine-readable medium comprising instructions which, when executed by a machine, cause the machine to perform operations including:
- determining a set of power measurements of signals received at a base station;
- calculating an average and a variance of the set of power measurements;
- calculating a predicted loading level of the base station based on the average and the variance of the set of power measurements;
- and
- determining whether to accept or deny connection requests based on the predicted loading level and a predetermined threshold.
