Abstract
For IP-based wireless systems in which base stations are connected by an IP network and communication among base stations is not controlled by the centralized management, a new system and method for realizing soft handoff by using encapsulation in order to distribute and gather a reproduced packet by the serving base station with other base stations and to transfer the serving role between the base stations as the mobile station moves is described.
