The present invention relates to the field of communications, and in particular, to an access processing method, a core management network element, and a network system. Background technique

With the rapid development of communication technologies, users are increasingly demanding communication technologies. In order to meet the increasing communication requirements of users, various new communication technologies have been introduced. Currently, 3rd Generation Partnership Project (3GPP) and non-3GPP (non-3GPP) standards organizations are studying a new access model: home access mode. Through the home access mode, user equipment (UE) can access the network through a universal IP access point, such as a digital wireless access point, such as a base station deployed in a home or community or within an enterprise. A Subscriber Line (DSL), a Cable Broadband, etc., are connected to the operator's mobile network. The licensed spectrum may be a universal mobile communication system UMTS Terrestrial Radio Access Network (UTRAN), an evolved universal mobile communication system (Evolved UMTS Terrestrial Radio Access Network, E-UTRAN), Code Division Multiple Access (CDMA), Worldwide Interoperability for Microwave Access (Wimax), Wireless Local Area Network (WLAN), High Rate Packet Data (High Rate Packet Data, HRPD) The spectrum used by the network.

In order to restrict the UE from accessing a specific access network element, such as a home wireless access point or a specific wireless access point, a Closed Subscriber Group (CSG) mechanism is introduced, and the CSG identifies some UEs (or For users, Subscriber), these UEs allow access to one of the carriers Or multiple cells, but these cells restrict access to other UEs, thereby implementing differentiated services for the UE. A CSG area contains one cell or multiple cells, and these cells define access to a group of UEs. A CSG area is identified by a CSG identifier (ID). A home wireless access point or wireless access point with CSG functionality has two access modes: Hybrid access mode and Closed access mode. For the hybrid access mode, CSG members (which can also be described as CSG users or CSG UEs) and non-CSG members (ie, the user is not a user in the CSG, can also be described as a non-CSG user or a non-CSG UE) Both can access the carrier's network through a CSG-enabled home wireless access point or wireless access point; for closed access mode, only CSG members can pass the CSG-enabled home wireless access point or wireless The access point accesses the carrier's network. In order to better implement differentiated services, CSG members can be divided into different priorities, and members with different priorities can enjoy different services.

For the operator, after the user accesses the carrier's network through the CSG-enabled home wireless access point or wireless access point, the operator's charging rate or charging mode for these users (Charging) Model ) The billing rate or billing mode may be different after the user accesses the operator's network through the macro network; for the CSG of the hybrid access mode, the CSG member and the non-CSG member The billing rate or billing mode may also be different.

In the prior art, the charging system cannot obtain the CSG information of the UE, so that the charging system cannot implement the CSG information based on the UE to determine the charging rate or the charging mode, and further differentiates the UE. Summary of the invention
