Embodiment 1

[0071] When the RG in the fixed broadband network is activated, IP Edge establishes an IP-CAN session to PCRF_RG on the Gxd interface for the RG. Assuming that the fixed broadband network accesses the core network through S2a-GTP, and subsequently, the 3GPP UE accesses through the RG and initiates a PDN connection, the PGW of the core network will establish an IP-CAN session for the UE to PCRF_UE on the Gx interface. PCRF_UE (ie PCRF of UE) will initiate interaction with PCRF_RG (ie PCRF of RG). Such as Figure 7b As shown, the process is as follows:

[0072] Step 1. The UE accesses the fixed broadband network and initiates a PDN connection process to access the core network.

[0073] Step 2. IP Edge sends a session creation request message to PGW, which carries the Line-ID (access line identifier) ​​corresponding to the RG currently accessed by the UE; the Line-ID is the access line authentication of IP Edge when the RG is activated obtained in the process;

[0074] Step ...

Embodiment 2

[0079] When the RG in the fixed broadband network is activated, IP Edge establishes an IP-CAN session to PCRF1 on the Gxd interface for the RG. Subsequently, the 3GPP UE accesses the network through the RG and initiates a NSWO connection, then the IP Edge initiates a new IP-CAN session to PCRF2 on the Gxd interface for the UE. PCRF2 will initiate the interaction with PCRF1. Such as Figure 7c As shown, the process is as follows:

[0080] Step 1. The UE accesses the fixed broadband network and initiates a NSWO connection;

[0081] Step 2. IP Edge sends an IP-CAN session establishment request message to PCRF_UE on the Gxd interface for the UE, which carries the Line-ID corresponding to the RG currently accessed by the UE;

[0082] Step 3-Step 4 are the same as Step 4-Step 5 of Embodiment 1.

[0083] Subsequent delivery and execution of the QoS policy is carried out according to the existing technology, that is, the PCRF_UE sends the QoS policy to the PCRF_RG through the esta...

Embodiment 3

[0085] When the RG in the fixed broadband network is activated, IP Edge establishes an IP-CAN session to PCRF_RG on the Gxd interface for the RG. Assume that the fixed broadband network accesses the core network in S2b mode, that is, the fixed broadband network gateway IP Edge will access the core network through the ePDG. Assuming that the 3GPP UE initiates a PDN connection, the Line-ID will be passed to the 3GPP AAA through the fixed broadband network, and then passed to the ePDG. If the GTP protocol is used between ePDG and PGW, the Line-ID is passed from ePDG to PGW and then to PCRF; if the PMIP (Proxy Mobile IP) protocol is used between ePDG and PGW, the Line-ID is directly sent by ePDG Passed to PCRF on the Gxb interface. The following figure takes the PMIP protocol as an example, such as Figure 7d Shown:

[0086] Step 1. The UE accesses from the fixed broadband network and initiates an access authentication process. In this process, the fixed broadband network send...

Abstract

The embodiment of the present invention discloses a policy and charging control entity addressing method and equipment, which relate to the field of wireless communication and are used to solve the policy and charging of terminal UE under the fusion architecture of fixed broadband access network and evolved packet core network EPC How the control entity PCRF addresses the PCRF of the home gateway RG. In the present invention, the gateway device sends the identification information of the RG to the PCRF of the UE, and the PCRF of the UE addresses the PCRF of the RG according to the identification information of the RG, and establishes a connection with the PCRF of the RG. It can be seen that this solution solves the problem of how the PCRF of the UE addresses the PCRF of the RG.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for addressing a policy and charging control entity. Background technique [0002] The Broadband Access Network Interworking (BBAI) topic of the 3rd Generation Partnership Project (3GPP) studies the 3GPP system and fixed broadband network interconnection technology. In this context, the 3GPP User Equipment (User Equipment) Equipment, UE) can access the operator's core network through the fixed broadband access network, and can also directly access the service network (such as the Internet) through the fixed broadband network. [0003] In the version (Release, R) 11 stage, a UE accesses the core network through a wireless local area network (Wireless Local Area Network, WLAN) of a fixed broadband network. figure 1 As shown, wherein, the broadband network gateway (BroadbandNetwork Gateway, BNG) is a fixed broadband network gateway, which provides functions...
