Abstract
The present invention is a system for distributing the reconnection attempts of multiple system users in a CDMA telephone system over a broad time window. The invention assigns a randomly initial wait time for each system user from a time window. After the initial wait time is assigned to a system user, any unsuccessful reconnection attempt by that user results in quadrupling the current wait time, until a maximum wait time window is reached. Once the maximum time window is reached, the system user continues to attempt reconnection every cycle of the maximum wait time until connection is maintained. By randomly assigning an initial wait time to each system user, the probability of system users attempting simultaneous reconnection is reduced, thus reducing the likelihood of reconnection collision.
