Caller identification method, and billing system and method using the same in internet telephony
摘要：
A caller identification system provides a caller identifier of an actual user rather than the conventional telephone number dependent on a caller terminal. Further, a caller base billing method and its system can bill an actual user by carrying out user authentication through a certification authority for a caller identifier that is independent of a caller terminal. The method includes the steps of receiving authentication information of the caller from a caller terminal; verifying the authentication information; and carrying out call setup if the authentication information and the certificate match, wherein the authentication information is generated by using a caller identifier and a private key that are applied by the caller, with no dependency on the caller terminal, and caller information corresponding to the caller identifier is transmitted to a callee terminal during call setup.
摘要（中）：

呼叫者识别系统提供实际用户的呼叫者标识符，而不是依赖于呼叫者终端的常规电话号码。 此外，呼叫者基本计费方法及其系统可以通过对独立于呼叫者终端的呼叫者标识符的认证机构进行用户认证来对实际用户进行账单。 该方法包括从呼叫者终端接收呼叫者的认证信息的步骤; 验证认证信息; 以及如果认证信息和证书匹配，则执行呼叫建立，其中通过使用呼叫者应用的呼叫者标识符和私钥来生成认证信息，而不依赖于呼叫者终端，以及对应于呼叫者信息的呼叫者信息 在呼叫建立期间，呼叫者标识符被传送到被叫终端。
