摘要： Disclosed is an encoding method of an encoder. The encoder generates a first MDCT coefficient by converting an input signal, and generates an MDCT index by quantizing the first MDCT coefficient. The encoder generates a second MDCT coefficient by inversely quantizing the MDCT index, and calculates an MDCT error coefficient by a difference between the first MDCT coefficient and the second MDCT coefficient. Next, said encoder generates an error index by encoding the MDCT error coefficient, and generates a gain index corresponding to a gain of the first MDCT coefficient from the first MDCT coefficient and the second MDCT coefficient.

摘要： The method involves using a file of discount rates for each information supplier. The number and identifier of the supplier are received, and the number used as an index to a principal table (311) in a database of information suppliers. This table is examined to verify that data corresponding to the index value are present in the principal table. An error message is transmitted and processing stopped if there is no match, and if there is a match the data needed to compute the discount is extracted from the database. The result of the calculation is delivered to the point where the service is delivered.

摘要： A method of processing information charge discount rates for service subscribers in a premium-rate service. Information charge discount rate data for each service subscriber is registered and a service subscriber number and a calling number are received from Service Switching Point. The received service subscriber number is designated as an index value of a main table in a service subscriber database and the main table is then retrieved to check whether data corresponding to the designated index value are present in the main table. If the data corresponding to the designated index value are present, a service feature classification data field in the main table is retrieved to check whether the service subscriber has subscribed to a flexible charging-by-day/time service. If the service subscriber has subscribed, data are read from a day/time classification data field in the main table, and a specific data information charge discount rate, a specific day information charge discount rate, a specific time information charge discount rate and a holiday information charge discount rate are calculated according to the read data. The calculated information charge discount rates are transmitted together with an information charge class and a called number to a service switching point.

摘要： An improved call distribution processing method for a called line number computation in a premium-rate service of Intelligent Network is provided. The method is capable of routing to various called numbers designated in accordance with a calling area, performing a call distribution in accordance with the capacity of a called party number, and routing to a called number since this method does not degrade call processing performance of the system. Since a system load is less, the occurrence frequency per each digit when digits from one to a hundred is performed N-times evenly occurs, and the values which was generated in the function of the random numbers does not occur in the identical pattern.

摘要： The method involves use of a first sequence (141-146) which records a class of an information system depending on the subscriber and the charging rate as a function of the day, time and other information. The additional information may include the regional dialling code of the called number, and call prices which are specific to the subscriber. A second sequence (147-153) includes specification and indication data for a code value which indicates a free number when data is absent and executes a call distribution service function. The service function depends on the call zone when data are present and when the subscriber has subscribed to the service and transmits the calculated call number.
