Abstract: A method and apparatus for load balancing in a wireless network is provided. For example, this invention is directed to a technique for balancing bearer load across a bank of traffic processors associated with a high-availability radio network controller (RNC). Instantaneous measures (e.g. processor occupancy) are used as one parameter for such load balancing. Predictive measures are used as another parameter. The predictive measures indicate the degree to which a given processor can become busy in the next few intervals of time and is based on the unrealized potential as derived from the established data rate of bearer sessions. The overall technique described herein allows for an even distribution of highly bursty traffic, with an objective of preserving call quality during periods of increased network congestion.

Abstract: A method is provided of alleviating an overload condition of a base station of a code division multiple access (CDMA) network for mobile telecommunications. The base station has a plurality of mobile user terminals in its radio coverage area. At least some of the mobile user terminals are in a first mode in which a request for non-emergency call connection can be made. The method involves detecting an overload condition of the base station and in response transferring a mobile user terminal from said first mode to a second mode in which the mobile user terminal can no longer make a request for non-emergency call connection.
