Abstract

An apparatus and method for serving sector maintenance in a wireless communication system is described. A forward link serving sector (FLSS) change command (ChangeFLSS) is received and it is determined if a FLSS in the ChangeFLSS command is a member of a NonSynchronousSubset. If the determination is positive, a reverse link serving sector (RLSS) and a dedicated RLSS (DRLSS) in the public data may be updated to be equal to the FLSS in the ChangeFLSS command, and indications that the RLSS and the DRLSS have changed may be issued. Otherwise, the FLSS and a dedicated FLSS (DFLSS) in the public data may be updated to be equal to the FUSS in the ChangeFLSS command, and indications that the FUSS and the DFLSS have changed may be issued.
