Embodiment Construction

[0082] Figure 5 It is a flow chart of the method for obtaining roaming information in the present invention, such as Figure 5 shown, including the following steps:

[0083] Step 500: The gateway connected to the P-GW transmits the roaming information to the P-GW.

[0084] In this step, in the fixed-network-mobile convergence architecture, the system accessing the EPS through the fixed-line line may be an H(e)NB subsystem or a WLAN. in,

[0085] In the H(e)NB subsystem, the gateway connected to the P-GW is the S-GW, and the roaming information transmitted is the S-GW network element address or user location information;

[0086] In the WLAN, the gateway connected to the P-GW is the ePDG, and the roaming information transmitted is the ePDG network element address or the visited public land mobile network identification (VPLMN ID) information.

[0087] Step 501: The P-GW forwards the received roaming information to the H-PCRF. In this way, the H-PCRF extracts the VPLMN ID ...

Abstract

The invention discloses a method and system for obtaining roaming information. The method comprises the steps of: transmitting the roaming information to a P-GW (Packet Data Network Gateway) by a gateway connected with the P-GW, and forwarding the received roaming information to an H-PCRF (Home-Policy and Charging Rules Function) by the P-GW. Therefore, a VPLMN ID (Public Land Mobile Network) is extracted from the obtained roaming information by the H-PCRF. According to the invention, in a fixed network mobile converged infrastructure, the roaming information is transmitted, so as to ensure that a proper V-PCRF (Visited-Policy and Charging Rules Function) is determined by the H-PCRF.

Description

technical field [0001] The invention relates to fixed-network-mobile convergence architecture technology, in particular to a method and system for acquiring roaming information. Background technique [0002] figure 1 It is a schematic diagram of the composition of the existing EPS, such as figure 1 As shown, the Evolved Packet System (EPS, Evolved Packet System) of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) is formed by the Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network) , Mobility Management Entity (MME, Mobility Management Entity), Serving Gateway (S-GW, Serving Gateway), Packet Data Network Gateway (P-GW, Packet Data Network Gateway) and Home Subscriber Server (HSS, Home Subscriber Server). [0003] Such as figure 1 As shown, the EPS supports intercommunication with non-3GPP systems, wherein intercommunication with non-3GPP systems is realized through S2a / b / c interfa...
