ABSTRACT:
A method wherein an autonomous system that must move off of the current DCCH channel: determines a new DCCH channel; transmits on the current DCCH channel a new PSP/POF list in which the new DCCH replaces the current DCCH, transmitting the new PSP/POF list for a time sufficient for mobile stations camped on the current DCCH to update their PSP/POF lists; and begins broadcasting on the new DCCH channel. Whereby a MS camped on the current DCCH: receives the new PSP/POF list; updates its internal tables; loses communications on the current DCCH; performs the Control Channel Reselection procedure; finds the new DCCH channel; and camps on it.
