Network Interconnection System And Method With Separated Controlling And Bearing

摘要

A network interconnection system and method with separated controlling and bearing is presented. The system includes a radio access network (RAN) and a corresponding core network (CN). The RAN includes a base station network element and a base station controller (BSC). The BSC is set to separate the controlling and the bearing and includes an RAN-Server and a radio gateway (RGW). The RAN-Server has controlling plane functions of a radio network controller (RNC) and a handover controlling function between the wired access and the radio access for supporting the handover controlling between the wired access and radio access. The RGW has the user plane functions of the RNC and has a multi-to-multi connection relationship with the base station network element. The system reuses the standard Iu or Iur interface as far as possible, implements the smooth evolution of the current UTRAN architecture.
