Abstract: PURPOSE: An apparatus and a method for fabricating an optical fiber grating are provided to reduce a fabrication time, thereby improving the yield, and to fabricate many optical fiber grating at the same time. CONSTITUTION: An apparatus for fabricating an optical fiber grating consists of a high-power laser beam source(10), a lens(20) focusing a laser beam, and a phase mask(30), and a fixing bar(41) supporting an optical fiber(50a,50b). The fixing bar is formed with a V-groove(44a,44b) for holding the optical fiber. The phase mask is installed to contact with a non-coating portion of the optical fiber. A grating being formed on the optical fiber due to a refraction variation of the optical fiber core having the photosensitivity. Two or more optical fibers are uniformly arranged. The phase mask is disposed on the optical fiber so that the phase mask covers an area of the optical fiber grating. The laser beam which changes the refraction degree is irradiated on the phase mask to cover the area of the optical fiber grating. In this way, many optical fiber grating are formed at the same time.

A local maximum energy value detector(400) sequentially selects the energy values calculated in the energy value calculator(300), to detect a local maximum energy value by the code search block without setting up a reference value. If the detected local maximum energy value is larger than a presently stored energy value, a maximum energy value storage(500) stores the detected local maximum energy value as a new local maximum energy value. The microprocessor(800) sets initial values of the number of integration blocks, coherent integration and code search blocks, and controls the diffusion codes to be consecutively outputted if the input data is inputted. And the microprocessor(800) controls the integration of the parallel correlator(200), and reads the stored local maximum energy value every end of search corresponding to the number of the code search blocks, to decide whether to detect the local maximum energy value.

Abstract: PURPOSE: A method for billing a QNC(Quick Net Connect) among wireless data call services is provided to classify an asynchronous data call setting up failure and a QNC call, and to process a byte number and a packet number transmitted from an IWF(Inter-Working Function) as bills. CONSTITUTION: An MCC(Mobile Call Control)(1) transmits a signal notifying a call release to an FRC(Frame Relay Control Block)(2,3). According to the signal, the FRC(3) transmits a call release message to an IWF(Inter-Working Function,4). The IWF uses the call release message. If a corresponding call service is a QNC(Quick Net Connect) call, the IWF converts a service option into from an asynchronous data call to a packet call, and combines the service option, a byte number and a packet number, then transmits a message converted into a determined format to the FRC(3). If the packet number exists in the transmitted message, and the service option is converted into the packet call, the FRC(3) decides that the corresponding call service is the QNC call. If not, the FRC(3) decides that the corresponding call service is a setting up failure of the asynchronous data call. The FRC(3) changes the setting up failure of the asynchronous data call into an interworking error, and transmits the interworking error to the MCC(1). The FRC(3) uses billing information, and transmits the asynchronous data call and QNC classification information, the byte number, the packet number and service option information to the MCC(1), then process the byte number and the packet number as bills.
