Abstract: A function for selecting and determining a receiving mode in a telephone is provided to enable a receiver to protect his privacy without missing important calls by transmitting an automatic response message if a call is received in case a call denial function is required when the receiver is in bed or conference. The user of a mobile phone establishes a call denial mode. If a caller makes a call to the user, the mobile phone sends an automatic response message to the caller. Listening to the automatic response message, the caller makes a decision to select a key button. In case the caller selects and presses the first key button to make a call connection with the user, the mobile phone automatically transfers to a generic receiving mode and rings a bell. If the caller selects the second key button to leave a message only, the mobile phone receives the message and outputs a message destination sound.

Abstract: A system and a method for billing based on client-server are provided to reduce risk caused by repeated works and distribute a load of a billing process by dualizing the billing system into a previous billing processing system and an integrated billing processing system. A billing system comprises two procedures performed by a previous billing processing system and an integrated billing processing system. The previous billing processing system obtains a CDR(Call Detail Record) from an exchange(S402), creates a BAN(Billing Account Number) by using the CDR and provides it to the integrated billing processing system(S404). The integrated billing processing system stores the received BAN record in a BAN record database, and creates a cycle by extracting the BAN record corresponding to a specified condition(S406). The integrated billing processing system assigns the created cycle to a selected billing processor. The billing processor determines total charge of this month including the charge in arrears of last month(S410). Billing information including the total charge is converted into a demand file having a format defined according to related organizations(S412).

Title: Resonator and rf filter using the resonator

Abstract: A resonator and an RF(Radio Frequency) filter using the same are provided to improve a Q factor of the RF filter by forming an upper portion of the resonator in a cylindrical shape and a lower portion of the resonator in a cone-like shape. An RF filter includes plural resonators(300), a partition unit(302), a housing(304), an input connector(306), an output connector(308), and a tuning bolt. Eight cavities are formed in the RF filter by the partition unit. The resonators are contained in the respective cavities. The cavities adjust an RF signal coupling amount of the resonator. An inner surface of the housing of the RF filter is processed with a silver coating. The tuning bolt is formed on an upper housing, so that a resonance frequency and a bandwidth of the RF filter are adjusted. The tuning bolt is formed to correspond to a portion of the cavity.
