The citations are incorporated herein by reference.

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method for establishing an Ethernet connection, a network element, and a network system.

Background technique

The network structure of the Worldwide Interoperability for Microwave Access (WiMA) system is shown in Figure 1. It consists of three parts: Mobile Station (MS) and Access Service Network (ASN). And the Connectivity Service Network (CSN). The ASN includes: a base station (BS) and an access service network gateway (ASN GW, referred to as an access gateway); the CSN includes: a prepaid server (PPS), a logical entity such as an authentication, authorization, and accounting server (AAA server). . The logical entities of the network are connected by R1 to R6 interfaces. The specific location of each interface is shown in Figure 1.

In the WiMAX network, the PCC (Policy and Charging Control) architecture is introduced as the policy system of the WiMAX network to perform resource authorization and QoS (Quality of Service) control during service establishment. The PCC is located between the service control layer and the access/bearer layer, and blocks the specific access/bearer layer technology and topology information to the service control layer. The PCC receives the service-related QoS request from the access control layer, and receives the QoS request. The information is combined with the admission control strategy, the topology information of the network, etc., and the received QoS request information is converted into IP QoS information, which is transmitted to the relevant access/bearer layer node and the service gateway node, and the nodes are based on the received information. Corresponding QoS control is implemented with its own functions.

Referring to Figure 2, the access gateway acts as a policy control enforcement point. The basic process for obtaining policy control information is:

Step 201: The access gateway receives an establishment IP access session request message. The IP access request message in this step may include a source IP address and a destination IP address corresponding to the IP access session.

Step 202: The access gateway performs information exchange with a Policy and Charging Function (PCRF), and obtains policy control information from the PCRF. The policy control information in the step is generated by the PCRF, and the policy control information includes: a policy decision, a charging control, and an IP classifier, where the policy decision includes: Gating Control and IP QoS information, and the charging control includes : Flow Based Charging (FBC X IP Splitter): The source IP address and destination IP address corresponding to the IP access session.

The specific manner of generating the policy control information by the PCRF is: generating IP QoS information according to the service-related QoS request received from the access control layer, and generating an IP classifier by using the source IP address and the destination IP address corresponding to the IP access session.

Step 303: The access gateway sends a response message for establishing an IP access message.

As the policy enforcement point, the access gateway establishes or modifies the bearer according to the policy control information, filters each uplink and downlink data packet according to the IP classifier in the PCC rule, and uses corresponding policy and charging control for the data packet that meets the classifier requirements. .

The inventor found in the process of implementing the present invention that the existing WiMAX network proposes the requirement of supporting Ethernet (Ethernet) service, and the PCC architecture in the WiMAX network only supports resource authorization and control based on IP address-based service establishment, and does not support Service binding and service dynamic establishment without IP address, and Ethernet service uses the MAC address of the terminal to identify the user and bind the service. Therefore, the existing WiMAX system cannot realize the resource authorization and control of the Ethernet service. The Ethernet service is transmitted in the WiMAX network as Best Effort. The access network in the WiMAX system cannot perform quality-assured transmission of the Ethernet service and perform different services for different levels of Ethernet services. QoS guarantee.

The source MAC address and the destination MAC address of the Ethernet service may be the source MAC address and the destination MAC address of an Ethernet service connection.

Referring to FIG. 3, a first embodiment of the present invention provides a method for establishing an Ethernet connection. When the terminal accesses the network, the access gateway obtains an QoS set of the Ethernet service from the AAA server, and the QoS set of the Ethernet service includes: The network service QoS information and the Ethernet classifier information are used to establish an access network bearer and an air interface connection suitable for transmitting the Ethernet service, and the method includes:

Step 301: The terminal and the network side perform basic capability negotiation, and the type of the Convergence Sublayer (CS) is: Ethernet CS.

During the basic capability negotiation process between the terminal and the network side, the access gateway can learn the source MAC address and destination MAC address of the Ethernet service requested by the terminal.

Step 302: The access authentication process of the terminal and the network side. The access gateway on the network side sends an authentication start request to the terminal, and the terminal carries the user identifier in the authentication response message, and the access gateway sends an access authentication request carrying the user identifier to the AAA server.

Step 303: After successfully authenticating the user, the AAA server generates an Ethernet QoS profile according to the user subscription information and/or the Ethernet policy preset by the local network. The AAA server sends an access authorization message Access-Accept to the access gateway, and the access authorization message carries: an Ethernet QoS profile.

The QoS set of the Ethernet service includes: Ethernet service QoS information and Ethernet classifier information. Ethernet service QoS information includes: maximum/minimum bandwidth, service level, and user priority. The Ethernet classifier information includes: a source MAC address and a destination MAC address of the Ethernet service. The foregoing QoS information of the Ethernet service may further include: CIR (committed information rate), CBS (Committed Burst Size), EIR (Excess Information Rate), EBS (Excess Burst) Size, excess block size) and CM (Color Mode) information.

The specific manner of generating the Ethernet service QoS set in this step is as follows: According to the user subscription information, the type and capability of the Ethernet service subscribed by the user are obtained, and the Ethernet preset from the local network is determined according to the type and capability of the Ethernet service subscribed by the user. Obtain the Ethernet service QoS set of the user in the network policy. The Ethernet policy preset by the local network includes a source MAC address and a destination MAC address of the Ethernet service.

In this step, the Ethernet service QoS set may be generated only according to the subscription information of the user, or the Ethernet service QoS set may be generated only according to the Ethernet policy preset by the local network, without affecting the implementation of the present invention.

Step 304: Generate QoS information carried by the access network, and establish a classifier carried by the access network. The specific implementation manner of the step is: mapping the QoS information of the Ethernet service into the QoS information carried by the access network, where the QoS information carried by the access network includes: the bearer identifier of the access network, the maximum/minimum bandwidth, the delay, the jitter, Transfer type and user priority, etc. An anchor data path function (ADPF) located on the access gateway establishes a classifier carried by the access network, and the classifier carried by the access network includes: a source MAC address and a destination MAC address.

Assume that the data path type of the current access network is a virtual local area network (VLAN), and the ADPF maps the VLAN identifier according to the priority information of the user in the QoS information of the Ethernet service. In this step, the QoS information of the Ethernet service is mapped into the VLAN QoS information, and the foregoing VLAN QoS information includes: a VLAN identifier, a maximum/minimum bandwidth, and a user priority.
