摘要： The present invention relates to a method of allocating channel codes for synchronous uplinks in a mobile communication system using a plurality of scrambling codes for the uplinks. This channel code allocating method, when a call is requested, searches for scrambling codes having at least one unused channel code, selects a foremost scrambling code among the found scrambling codes, and allocates an unused channel code in the selected scrambling code to the requested call, and, when a call is released, checks the number of channel codes and a scrambling code used by the released call, searches for active calls using another scrambling code posterior to the scrambling code the released call has used and not more channel codes than the number of the channel codes the released call has used, and re-allocates the channel codes and the scrambling code used by the released call to at least one active call if found. This method makes full use of channel codes in one scrambling code, as possible as it can, before using ones in next scrambling code, therefore orthogonality between channels which reduces interferences between channels is remarkably enhanced.

摘要： The present invention provides a caller with an arbitrary sound chosen by a called subscriber instead of a conventional RBT (RingBack Tone) without fails even in a flexible paging mode. In the present method: both exchangers check individually whether first information on replacing RBT or not and second information informing a route to a sound providing means have been stored for a called terminal, when an originating exchanger requests a trunk connection to said both exchangers according to a flexible paging procedure, and receive the first and the second information from a home location register after requesting if said information has not been stored, and request individually a trunk connection to the sound providing means while furnishing information identifying the called, based on the already-stored or the received first and the second information; and the originating exchanger selects one of the two paths connected to said both exchangers, and delivers to a caller an RBT replacing sound determined by the sound providing means that is received through the selected path
