Abstract:
1. A congestion management method in a wireless communications system in which a plurality of mobile terminals transmit data on a reverse link, the method comprising the steps of: selecting one of a plurality of overload control states based on a congestion overload metric, the plurality of overload control states having a hierarchical relationship with respect to each other; when the congestion overload metric has at least a first predetermined value that is indicative of the presence of an overload condition in the system that is being caused by a level of data traffic on the reverse link that is greater than what the reverse link can support, rejecting a connection request from another mobile terminal; and when the congestion overload metric has at least a second predetermined value that is greater than the first predetermined value, which second predetermined value is also indicative of the presence of an overload condition in the system, sending at least one message to a selected percentage of the mobile terminals instructing the selected percentage of mobile terminals to reduce their data transmission rate to zero for one or more predetermined time intervals, an active connection being maintained with the mobile terminals.
