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.

Abstract
Disclosed is a method of operating searchers, and setting a search information list and searching channels for the same. In a communication system, a method of searching channels, comprises the steps of generating a queue of priorities for each search mode, allocating to searchers search items having higher priorities based on the queue, and searching the search items by the allocated searchers.

7. A method of operating a searcher in a CDMA mobile communication system comprising:
-
setting a priority of a search item of an access search mode to the lowest in a queue of an access search mode if a last partial search of the access search mode is performed; setting a priority of a search item of a traffic preamble search mode to the lowest in a queue of a traffic preamble search mode if a last partial search of the traffic preamble search mode is performed; maintaining a priority of a search item of a traffic multi-path search mode in IS-95A/B system, to be the same in a queue of a traffic multi-path search mode if a last partial search of the traffic multi-path search mode is not performed; and setting the priority of a search item of a traffic multi-path search mode in IS-95A/B system, to the lowest in a queue of a traffic multi-path search if the last partial search of the traffic multi-path search mode is not performed.

8. A method of operating a searcher in a CDMA mobile communication system, comprising:
-
maintaining a priority of a search item of an enhanced access search mode to be the same in a queue of an enhanced access search mode if a last partial search of the enhanced access search mode is not performed; setting the priority of a search item of an enhanced access search mode to the lowest in a queue of an enhanced access search mode if the last partial search of the enhanced access search mode is performed; setting a priority of a search item of a traffic preamble search mode to the lowest in a queue of a traffic preamble search mode if a last partial search of the traffic preamble search mode is performed; and setting the priority of a search item of a traffic multi-path search mode, to the lowest in a queue of a traffic multi-path search mode if a last partial search of the multi-path search mode is performed.
