摘要： In a mobile station used in a cellular mobile telecommunication system that communicates on any one of a plurality of base station cellular channels depending on cell location of the mobile station, the system being adapted to selectively determine one of the channels to process a call with the mobile station and handoff a cellular call with the mobile station from a current channel to a new channel, a handoff system for detecting system and capability changes when a handoff has occurred. The handoff system includes a memory storing data representing parameters associated with the current channel. A forward communication channel is associated with the current channel for receiving data from a base station. The data includes a handoff message if a handoff is to occur. The handoff message includes parameters associated with the new channel. A comparator associated with the memory compares select stored parameters associated with the current channel to corresponding select received parameters associated with the new channel to determine if system or capabilities of the new channel differ from system or capabilities of the current channel.
