Abstract:
1. A method of operating at least one searcher in a CDMA mobile communication system, comprising: (a) setting a number of channels of a first queue of an access preamble search mode as a number of remaining access channels; (b) when a number of allocated searchers is less than that of all searchers, setting a first priority search item of the first queue for the access preamble search mode to a current search item and checking whether a search for the first priority search item in the first queue is possible; (c) when the search for the first priority search item is possible, allocating a searcher to the first priority search item of the first queue; (d) searching the first priority search item of the first queue in the access preamble search mode until the first priority search item is nulled; (e) repeating the (b), (c), and (d) steps until the number of allocated searchers is not less than that of all of the searchers; (f) when the number of remaining access channels is equal to ‘0’, setting a first priority search item of a second queue for a traffic preamble search mode to the current search item and allocating the searcher to the first priority search item of the second queue searching the first priority search item of the second queue in the traffic preamble search mode; and (g) when the first priority search item of the second queue is nulled, setting a first priority search item of a third queue for a traffic multi-path search mode to the current item and allocating the searcher to the first priority search item of the second queue searching the first priority search item of the third queue.
