Description

Interface establishing method and device
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for establishing an interface.
Background
A third generation partnership project (3 GPP) release 11(R11) broadband access interworking (BBAI) work project (WorkItem, WI) researches the interconnection and fusion problem of a fixed broadband network and a 3GPP mobile network, wherein a scenario that a User Equipment (UE) traffic is directly offloaded through a Broadband Network Gateway (BNG) without routing back to an Evolved Packet Core (EPC) network is researched, and how to charge the UE in the scenario is an important issue. One method in the current specification is to transmit the charging information of the UE through an interface (i.e., STa interface or SWa interface) between a BBF Authentication, authorization, and charging (AAA) Proxy (Proxy) and a 3gpp AAA Server (Server). In R11, for time reasons, only a method for establishing an interface between BBFAAAProxy and 3GPP aaaaserver to transfer UE charging information under 3GPP access authentication is studied. For the case of not performing 3GPP access authentication, there is no solution for how to establish the STa interface or SWa interface to charge the UE.
The 3GPP r11 work project BBAI researches the interconnection and fusion problem between a 3GPP network and a fixed broadband access network (defined by broadband forum, BBF, hereinafter referred to as BBF network), and is divided into three research stages (building block). The first part (building block1, BB1) researches the interconnection problem between the 3GPP network and the BBF network, and the traffic of the UE is routed back to the EPC network; the second part (building block2, BB2) studies the interconnection problem between 3GPP and BBF networks, but some traffic (e.g. Web browsing, FTP, etc.) of the UE can be offloaded directly to the operator's IP network through the BBF network, while for services such as IP Multimedia Subsystem (IMS) voice, etc., it still needs to go through the EPC network; the third part (building block3, BB3) studies the convergence problem of 3GPP and BBF networks, including two scenarios, UE traffic routing back to EPC network and direct offloading.
In the offload architecture in BB2, traffic of the UE is directly offloaded to the IP network of the operator through a gateway bng (broadband and network gateway) of the BBF network. The Broadband Policy Control Function (BPCF) entity is a policy control function entity of the BBF network, the Policy and Charging Rules Function (PCRF) entity is a policy and charging rules function entity of the EPC network, the BNG is connected to the BPCF through an internal interface R, and the BPCF and the PCRF are connected through an S9a interface. The BBF Authentication, authorization and accounting (AAA) Proxy (Proxy) is an AAA Proxy in the BBF network and is connected to a 3gpp AAA Server (Server) through a SWa/STa interface.
In a scenario where traffic of the UE is routed back to the EPC network, a packet data network GateWay (P-GW) is responsible for performing charging processing on the UE. In an offload scenario, one charging method in the current specification is to report the charging information of the UE through an interface between the BBFAAAProxy and the 3gpp aaserver. The BNG sends the charging information of the UE to the BBFAAAproxy, the BBFAAAproxy reports the charging information of the UE to the 3gpp aaserver through an interface between the BBFAAAproxy and the 3gpp aaserver, and the 3gpp aaserver sends the charging information to an online charging system (online charging system, OCS)/offline charging system (OFCS) through a SWo/SWf interface.
Because R11 research time is limited, an important premise for stipulating charging using an interface between the BBFAAAProxy and the 3GPP aaserver is that 3 GPP-based access authentication is performed, and the interface between the BBFAAAProxy and the 3GPP aaserver can be established only after the 3 GPP-based access authentication is performed, and can be used for transmitting the charging information of the UE. However, in the case of not performing 3GPP access authentication, how to establish an interface between the BBFAAAProxy and the 3GPP aaserver and how to perform charging need further research.
In the 3 GPP-based access authentication process, the BNG sends an Extensible Authentication Protocol (EAP) message to the BBFAAAproxy, and the BBFAAAproxy routes the message to the 3GPP aaserver through the SWa/STa interface, thereby establishing a session on the SWa/STa interface.
In terms of the relation between quality of service (QoS) policy control and charging, after access authentication based on 3GPP is performed, the BPCF will initiate an IP connectivity access network (IP-CAN) session established to the PCRF for receiving the QoS policy issued from the PCRF. Currently, the BBAI concludes that for the case where QoS can be provided to a UE, the UE needs to be charged; and for the case that QoS cannot be provided to the UE, whether charging for the UE is required is FFS.
In the offload architecture in BB3, the traffic of the UE is also offloaded directly to the IP network of the operator through the BNG, except that in the converged architecture, the BNG is directly connected to the PCRF through the Gxd interface. No charging method has been determined in BB3 at present, but the method in BB2 is still possible for use in BB 3.
In summary, in BBAI, charging for offload traffic is an important problem, and in a method for transferring UE charging information through an interface between a BBFAAAProxy and a 3GPP aaserver proposed in the current specification, an important premise is that 3 GPP-based access authentication is performed, so that an interface between the BBFAAAProxy and the 3GPP aaserver can be established, and for a case where 3 GPP-based access authentication is not performed, how to establish an interface between the BBFAAAProxy and the 3GPP aaserver to implement charging for UE has no solution at present.

However, in the prior art, if the interface between the BBFAAAProxy and the 3GPP aaserver is used to transmit the charging information, the interface between the BBFAAAProxy and the 3GPP aaserver must be established through the 3 GPP-based access authentication process, and for the case where the 3 GPP-based access authentication is not performed, there is no method for establishing the interface between the BBFAAAProxy and the 3GPP aaserver. Compared with the prior art, the invention provides a method for establishing an interface between the BBFAAAproxy and the 3GPP AAAAServer under the condition that 3 GPP-based access authentication is not performed.
