Mobile communication system that supports soft handoff between switching stations and method for implementing handoff

摘要

A mobile communication system is disclosed that supports soft handoff between switching stations and increase service quality. The mobile communication system can include at least one mobile switching stations having a first inter network that controls a plurality of base station controllers and at least one local switching stations coupled to the mobile switching stations. Each of the local switching stations can include a second inter network that provides a communication path between the mobile switching stations. A method for implementing handoff between switching stations can include determining at any mobile station whether an implementation condition of handoff is satisfied, determining a type of handoff at the serving base station controller using pilot information of peripheral base stations when an implementation condition for handoff is satisfied, and implementing soft handoff using an interface between a first inter network and a second inter network provided to the mobile switching station if the handoff occurs between the mobile switching stations.
