Abstract

Abstract A method and apparatus for reestablishing a call after a call has been disconnected or after the quality of the call has become bad is disclosed. A disconnected mobile station scans the signal strength of surrounding base stations and accesses the base station with the highest signal strength. The mobile station then initiates a new call back to a service node. The base station then assigns the mobile station a traffic channel and the service node reconnects the call. In addition, a method for reestablishing a call in any communication network after the call has been terminated in a normal fashion is disclosed.
