Description

TECHNICAL FIELD The present invention relates to the field of mobile communication technologies, and in particular to a policy control method, apparatus, and system for fixed network mobile convergence. BACKGROUND OF THE INVENTION The 3rd Generation Partnership Project (3GPP) evolved Evolved Packet System (EPS) is composed of a Mobility Management Entity (MME) and a Serving Gateway (Serving Gateway). , referred to as S-GW), Packet Data Network Gateway (P-GW), Home Subscriber Server (HSS), Policy and Charging Rules Function (Policy and Charging Rules Function) , abbreviated as PCRF) entity and other supporting nodes, FIG. 1 is a schematic diagram of an EPS architecture according to the related art. As shown in FIG. 1, the MME is responsible for control planes such as mobility management, non-access stratum signaling processing, and user mobility management context management; the S-GW forwards data between the user access and the P-GW. And is responsible for buffering paging waiting data; P-GW is a border gateway of EPS and Packet Data Network (PDN) network, which is responsible for PDN access and forwarding data between EPS and PDN. The Evolved Packet Data Gateway (ePDG) is used for the untrusted non-3GPP access network to access the 3GPP EPS core network. The PCRF is mainly used for the decision making of network resource management policies and the formulation of charging rules. . The PCRF provides network control rules based on service data flows, including traffic data flow detection, gating, Quality of Service (QoS) control, and data flow-based charging rules. The PCRF sends its policy and accounting rules to the Policy and Charging Enforcement Function (PCEF). The PCRF also needs to ensure that these rules are consistent with the user's subscription information. The PCRF formulates the policy and charging rules based on: obtaining the information related to the service from the application function (Application Function, referred to as AF); obtaining the subscription information with the user from the Subscription Profile Repository (SPR); Obtain network information related to the bearer and policy information configured on the PCRF.

The EPS supports interworking with a non-3GPP system. The interworking between the EPS and the non-3GPP system is implemented through the S2a/b/c interface, and the P-GW serves as an anchor between the 3GPP and the non-3GPP system. As shown in FIG. 1, the non-3GPP system can be classified into trusted non-3GPP IP access and untrusted non-3GPP IP access. The trusted non-3GPP IP access can be directly connected to the P-GW through the S2a interface; the untrusted non-3GPP IP access needs to be connected to the P-GW through the ePDG, the interface between the ePDG and the P-GW is S2b, and the user equipment (User Equipment, referred to as UE) An IPSec secure tunnel is used to encrypt the signaling and data between the ePDG and the ePDG. S2c provides user plane-related control and mobility support between the UE and the P-GW. The supported mobility management protocol is Mobile IPv6 support for dual stack Hosts and Routers (DSMIPv6). . At present, many operators pay attention to Fixed Mobile Convergence (FMC), and research on the convergence of fixed networks defined by the 3GPP network and Broadband Forum (BBF). The FMC is based on the architecture of the EPS and non-3GPP systems as shown in Figure 1. On the one hand, the BBF network can support the access of fixed network users. On the other hand, the BBF network can also support mobile users to access the EPS network through it. 2 is a schematic diagram of an architecture of a BBF network accessing an EPS network according to the related art. As shown in Figure 2, the BBF network and the EPS network are interoperable. If the EPS network considers the BBF network as an untrusted network, the BBF network needs to access the EPS network through the ePDG. A residential gateway (Residential Gateway, hereinafter referred to as RG) is deployed in the customer premises network, and a WiFi access point (Wireless Fidelity Access Point (WiFi AP) is deployed at the same time. The WiFi AP accesses the BBF network through the RG, and the user is fixed on the one hand. The fixed network is accessed through the customer premises network. On the other hand, the mobile user can also access the customer premises network and implement attachment to the EPS network through the BBF network. Based on the above-mentioned converged network architecture, mobile users can access through fixed network or through mobile access, and can switch between different access networks. FIG. 3 is a flow chart of a NAT RG power-on attachment in a routing mode in the related art. Step S301: The RG is powered on, and the authentication process defined by the BBF is performed. The BBF AAA may provide the default QoS of the RG to the IP edge entity (IP Edge), which assigns an IP address to the BB's BBF user session. Step S302: The IP Edge/PCEF sends an IP-CAN session establishment indication to the PCRF, carrying the RG user identity (if any), the access line identity (physical and logical circuit identification), and the default QoS parameters (if any). IP address (IPv4 address and/or IPv6 prefix); Step S303: The PCRF sends a message to the SPR to obtain the RG-related subscription information. Step S304: The SPR returns an acknowledgement message to the PCRF, carrying the subscription information. Step S305: The PCRF is contracted according to the contract. Data development strategy. The PCRF may modify the default parameters obtained from the PCEF. The PCRF sends a policy to the IP Edge/PCEF, including the default QoS, the PCC rule, the event trigger, and the like. Step S306: The fixed network performs the policy delivered by the PCRF. Through the above process, the IP Edge/PCEF and the PCRF establish an IP-CAN session (ie, a Gxd session) for policy control of the fixed subscription session of the RG. In addition, for the 3GPP UE to access the RG, the RG will perform access authentication on the 3GPP UE, and the RG allocates the IP address of the private network to the UE. The IP Edge can only perceive the IP address of the RG, and the PCRF cannot perceive the access of the 3GPP UE. Therefore, for the service initiated by the 3GPP UE, the PCRF cannot perform policy decision according to the special subscription of the 3GPP UE, and thus cannot perform differentiated policy control for different 3GPP UEs or 3GPP UEs and fixed network devices under the same RG. In another related art, after the process of FIG. 3 is executed, after the 3GPP UE accesses the RG, the process shown in FIG. 4 is performed. Step S401: The 3GPP UE accesses the RG, and performs a 3GPP-based access authentication process. The HSS/3GPP AAA may provide the default QoS of the RG to the IP Edge through the BBF AAA, and the RG reserves a port number set for the 3GPP UE, and notifies the IP Edge of the correspondence between the user identity and the port number set. Step S402: The IP Edge/PCEF sends an IP Connectivity Access Network (IP-Accessive Network, IP-CAN) session establishment indication to the PCRF, and carries the user identifier and access line identifier (physical and logical circuit identifier) of the 3GPP UE. The default QoS parameters of the 3GPP UE, the IP address (the IPv4 address and/or the IPv6 prefix, which is the address assigned to the RG in the process of Figure 3) and the port number set; at this time, the IP Edge and the PCRF can be based on the IP address and port number. The set determines if the traffic data flow belongs to this 3GPP UE. Step S403: The PCRF sends a message to the SPR to obtain the subscription information related to the 3GPP UE. Step S404: The SPR returns an acknowledgement message to the PCRF, and carries the subscription information. Step S405: The PCRF formulates a policy according to the subscription data. The PCRF may modify the default parameters obtained from the IP Edge/PCEF. The PCRF sends a policy to the IP Edge/PCEF, including the default QoS, the PCC rule, the event trigger, and the like. Step S406: The fixed network performs the policy delivered by the PCRF. Through the flow of FIG. 3 and FIG. 4, the IP Edge/PCEF is a Gxd IP-CAN session established by the RG and the 3GPP UE, respectively, and the RG reserves a port number set for the 3GPP UE, and identifies the 3GPP UE and performs services for the future. Offer possible. The PCRF may be able to provide a differentiated policy charging control method. Then, although the solution shown in FIG. 4 proposes a solution, since the RG is required to reserve the port number before the 3GPP UE conducts the service, the wasted port resources are greatly increased, and new requirements are imposed on the capability of the RG. In addition, there is currently no standardized way to notify the IP Edge of the association between the user ID and the port number set. When RG and IP Edge are from different manufacturers, interoperability is still not possible.
