tax system, tax procedures and control mechanism

摘要

A control system includes a user management server or server group, a Service Policy Decision Function (SPDF) server, an Access-Resource and Admission Control Function (A-RACF) server, and a control interface location between the user management server or server group and the SPDF n server for transmitting the information. In addition, a control method using the control system above and a control device are provided. By the technical solutions above, when there are many access network operators connecting to the uniform network operation operator, the problem that the SPDF server searches the A-RACF server is solved, and the user information is acquired by setting the interface between the SPDF server and the user management server or server group.
