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： A constant current controlling part of an LED array driving apparatus includes a PWM IC including an RT/T terminal for outputting a sawtooth wave voltage, a COMP terminal for receiving a comparison voltage to be compared with the sawtooth wave voltage, an output terminal for outputting a pulse signal that is turned off during an interval where the sawtooth wave voltage is higher than the comparison voltage and turned on during an interval where the sawtooth wave voltage is lower than the comparison voltage, and a comparison voltage setter setting the comparison voltage inputted to the COMP terminal. When an overvoltage is applied to the LED array or the LED array is to be turned off by an external dimming control signal, the comparison voltage setter sets the comparison voltage to a value lower than a lower limit of the sawtooth wave voltage.

摘要： The present invention relates to method and apparatus for providing an arbitrary sound chosen by a called subscriber instead of ringback tone to a calling subscriber. In this present invention, if a call is received, a terminating exchanger requests a trunk connection to a sound db server based on the first information on whether or not to replace a ringback tone and the second information on a route to the sound db server that are received from a home location register (HLR), and provides a called subscriber identification for the sound server. Then, the sound db server searches its db for a sound specified by the called, and provides the found sound for the caller instead of a conventional ringback tone via the terminating exchanger connected through a trunk. Through this sequential procedure of network elements, a caller can hear a sound specified by a called instead of a dry ringback tone.
