Description

Access processing method, core management network element and network system

technical field

The invention relates to the communication field, in particular to an access processing method, a core management network element and a network system.

Background technique

With the rapid development of communication technology, users have higher and higher requirements for communication technology. In order to meet the increasing communication requirements of users, various new communication technologies have been introduced; currently the Third Generation Partnership Project (3GPP) and African The 3GPP (non-3GPP) standard organization is studying a new access mode: the home access mode; through the home access mode, the user equipment (User Equipment, UE) can pass through the home wireless access point (such as deployed at home or Base stations in communities or enterprises), use licensed spectrum, and connect to the mobile network of operators through common IP access networks (such as digital subscriber lines (DSL: Digital Subscriber Line), cable broadband (Cable broadband), etc.). Among them, the licensed spectrum can be Universal Mobile Telecommunications System Terrestrial Radio Access Network (UMTS Terrestrial Radio Access Network, UTRAN), Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (Evolved UMTST Terrestrial Radio Access Network, E-UTRAN), Code Division Multiple Access (Code Division Multiple Access, CDMA), Microwave Access Global Interoperability (Worldwide Interoperability for Microwave Access, Wimax), Wireless Local Area Network (Wireless Local Area Network, WLAN), High Rate Packet Data (High Rate Packet Data, HRPD) and other networks spectrum used.

In order to restrict UE access to specific access network elements (such as home wireless access points or specific wireless access points, etc.), a closed subscriber group (Closed Subscriber Group, CSG) mechanism is introduced. CSG identifies some UEs (or called Subscriber), these UEs are allowed to access one or more cells of the operator, but access to these cells is restricted for other UEs, so as to realize differentiated services for UEs. A CSG area (area) includes a cell (Cell) or multiple cells, and these cells are limited to access to a group of UEs. A CSG area is identified by a CSG identifier (ID). The home wireless access point or wireless access point with CSG function has two access modes: hybrid access mode (Hybrid access mode) and closed access mode (Closed access mode). For hybrid access mode, CSG members (also described as CSG users or CSG UEs) and non-CSG members (that is, users who are not a user in CSG, can also be described as non-CSG users or non-CSG UEs) are both You can access the operator's network through home wireless access points or wireless access points with CSG functions; for closed access mode, only CSG members can use home wireless access points or wireless access points with CSG functions The entry point is connected to the carrier's network. Among them, in order to better realize differentiated services, CSG members can be divided into different priorities, and members with different priorities can enjoy different services.

For operators, after users access the operator's network through home wireless access points or wireless access points using CSG functions, the operator's charging rate (Charging rate) or charging mode (Charging rate) for these users model) may be different from the charging rate or charging mode after the user accesses the operator's network through the macro network; for a CSG with hybrid access mode, the The billing rates or billing modes may also be different.

In the prior art, the charging system cannot acquire the CSG information of the UE, so that the charging system cannot determine the charging rate or charging mode based on the CSG information of the UE, and then perform differentiated charging on the UE.
