<p>PROBLEM TO BE SOLVED: To provide a control mechanism that will return a system to a stable condition if an overload condition occurs on an access medium.SOLUTION: An overload or congestion condition on an access medium 24 of a communication network 22 is indicated by at least one condition that indicates an amount of access attempts on the access medium 24 corresponding to congestion or overload of a capacity of the access medium 24. Example conditions include an occupancy level of the access medium, an average number of access probes associated with successful access attempts, a relationship between received power and interference, an emergency condition and network configuration or maintenance procedures. When congestion or overload occurs, a technique for reducing the congestion or overload to stabilize the access medium is to throttle the number of access attempts by reducing the number of users making access attempts or the frequency of user access attempts.</p> |
