DEDICATED CONTROL CHANNEL HANDOFF IN CDMA COMMUNICATION SYSTEM

摘要

A handoff method in a CDMA communication system using Walsh codes and quasi- orthogonal codes. To implement a handoff, a new base station to which a call is switched notifies a serving base station of an available quasi-orthogonal code, if the new base station has no available Walsh codes. The serving base station transmits a handoff direction message to a mobile station and the mobile station communicates with the new base station using the quasi- orthogonal code included in the handoff direction message.
