Abstract  Abstract

The invention allows a mobile station (2) when in a system access state. This allows the mobile station (2) capable of receiving base station (26) with high signal-to-noise ratio thereby reducing message error rate. This avoids cannot receive a paging channel is lost call set-up. By allowing soft switching the base station (2) needs to send the channel assignment message on the paging channel by a plurality of base stations (26). Furthermore This ensures that mobile station (2) can be soft handoff to different base stations (26) and immediately have the new base station (26) assigns service channel of it.

A method and apparatus which permits handoffs while the mobile station (2) is in the system access state. This is achieved by providing for channel assignment messages to be sent over the paging channel of a plurality of base stations (26) which increases the probability of one of the messages getting through. In addition this assures the mobile station (2) will be able to handoff to a different base station (26) and have a traffic channel allocated to it on the new base station (26) without delay. In addition a method and apparatus which permits the mobile station (2) to be directly assigned into a soft handoff state upon traffic channel assignment.
