摘要： In a communication system where frame boundaries for the discrete frames for different users may be offset relative to one another, assignment of a remote unit (125) to a particular frame offset occurs by a processor (321) determining a frame offset belonging to a group that is the least busy group of all possible groups. In addition, during handoff of the remote unit (125) from a serving base station (130) to a neighboring base station, the remote unit (125) is attempted to be kept within the same call group, however should the same call group of the neighboring base station be filled, the remote unit (125) is placed in a second call group that is one call group prior to the current call group.
