Problems solved by technology

The main problem of this method is that the configuration information is relatively complicated, especially when the AF is a third-party service, it is difficult to update the configuration information, and when some S-GWs or trusted non-3GPP access gateways in the visited network or non-3GPP network When the BBERF function is supported, the AF will not be able to simply decide whether to subscribe to events based on the visited network where the UE is located

[0068] In this embodiment, the UE is image 3 In the application scenario shown, through the trusted non-3GPP access network and the DSMIPv6 protocol to access EPS, the 3GPP network supports dynamic PCC, but the trusted non-3GPP access network does not support dynamic PCC (the trusted non-3GPP access network and 3GPP networks belong to different operators). The method flowchart of the second embodiment of the present invention is as follows Figure 5 As shown, the specific steps are as follows:

[0069] 501: The UE accesses a trusted non-3GPP access network, the HSS / AAA and the UE perform mutual authentication, and the HSS / AAA authorizes the UE.

[0070] 502: After the authentication is successful, the UE negotiates with the trusted non-3GPP access gateway and decides to use the DSMIPv6 protocol for access, the UE performs a layer 3 attachment process, and the trusted non-3GPP access gateway allocates a CoA (care-of address) for the UE.

Abstract

The invention discloses a method and a system for realizing limited policy charging control. The method comprises the following steps that: a policy and charging rule function (PCRF) entity judges whether the visited network where user equipment (UE) roams supports the policy charging control (PCC); and if the visited network does not support PCC, the PCRF entity sends a message to an applicationfunction (AF), wherein the message carries an identifier for indicating the limited policy charging control deployment. Due to the adoption of the method and system of the invention, the AF can be informed of the current policy charging control deployment condition more conveniently and accurately while the limited policy charging control is realized; and the AF can perform corresponding operation, such as no event subscription or the event subscription canceling, according to the current policy charging control deployment condition, thereby fulfilling the aim of saving the system resources.

Description

technical field [0001] The invention relates to a method and system for realizing limited policy charging control. Background technique [0002] Such as figure 1 As shown, the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) Evolved Packet System (EPS for short) consists of the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, E- UTRAN), Mobility Management Entity (MME for short), Serving Gateway (S-GW for short), Packet Data Network Gateway (PDN GW or P-GW for short), home user server ( Home Subscriber Server (HSS for short), 3GPP Authentication, Authorization and Accounting (AAA for short) server, Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF for short) and other supporting nodes. [0003] Among them, MME is used for mobility management, processing of non-access stratum signaling and management of user mobility management context and other control plane relat...
