Description

Establishment method of Ethernet service, network element equipment and network system

technical field

The invention relates to the technical field of communication, in particular to a method for establishing an Ethernet service, a network element device and a network system.

Background technique

The network structure of the Worldwide Interoperability for Microwave Access (WiMAX) system is shown in Figure 1. It is mainly composed of three parts: mobile terminal (MobileStation, MS), access service network (Access Service Network, ASN) and Connect to the service network (Connectivity Service Network, CSN). ASN includes: base station (Base Station, BS) and access service network gateway (ASN GW); CSN includes: prepaid server (PPS), authentication, authorization and accounting server (AAA server) and other logical entities. Interfaces from R1 to R6 are used to connect the logical entities of the network. Refer to Figure 1 for specific locations of each interface.

In the WiMAX network, 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 shields the specific access/bearer layer technology and topology information from the service control layer. The PCC receives service-related QoS requests from the access control layer, and the received QoS request information Combined with the admission control policy and network topology information, it converts the received QoS request information into IP QoS information, and transmits it to the relevant access/bearer layer nodes and service gateway nodes. These nodes based on the received information and their own The function realizes corresponding QoS control.

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

Step 201, the access gateway receives an IP access session establishment request message. The IP access session 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 exchanges information with a policy and charging control entity (Policy and Charging Function, PCRF), and obtains policy control information from the PCRF.

The policy control information in this step is generated by PCRF, and the policy control information includes: policy decision, charging control and IP classifier, wherein, the policy decision includes: gate control (Gating Control) and IP QoS information, and charging control includes : Flow Based Charging (FBC). The IP splitter includes: a source IP address and a destination IP address corresponding to the IP access session.

The specific way for PCRF to generate policy control information is to generate IP QoS information according to the service-related QoS request received from the access control layer, and generate an IP classifier according to the source IP address and destination IP address corresponding to the IP access session.

Step 303, the access gateway sends a response message for establishing an IP access session.

As a policy enforcement point, the access gateway establishes or modifies the bearer according to the policy control information, and filters each uplink and downlink data packet according to the IP classifier in the PCC rule. Once the data packet meets the requirements of the classifier, the corresponding policy and billing are used control.

The inventor finds in the process of realizing the present invention: the existing WiMAX network proposes to support the demand of Ethernet (Ethernet) business, because the PCC framework in the WiMAX network only supports the resource authorization and control based on the business establishment of IP address, does not support There is no IP address service binding and service dynamic establishment, and the Ethernet service uses the MAC address of the terminal to identify the user and bind the service, so the existing WiMAX system cannot realize the resource authorization and control of the establishment of the Ethernet service. Therefore, the transmission of the Ethernet service on the WiMAX network is best-effort (Best Effort) transmission, and the access network in the WiMAX system cannot perform quality-guaranteed transmission of the Ethernet service and different levels of Ethernet services Perform different QoS guarantees.

Detailed ways

An embodiment of the present invention provides a method for establishing an Ethernet service, including: acquiring Ethernet service QoS information and Ethernet classifier information; the Ethernet classifier information includes: the source MAC address and destination MAC address of the Ethernet service Address; according to the Ethernet service QoS information and the source MAC address and destination MAC address of the Ethernet service, establish an access network connection for carrying the Ethernet service data. Using the technical solution provided by the embodiment of the present invention, the Ethernet service can be established in the wireless network.

Referring to FIG. 3 , Embodiment 1 of the present invention provides a method for establishing an Ethernet service. When a terminal accesses the network, the method establishes an access network bearer and an air interface connection suitable for transmitting Ethernet services. The method includes:

Step 301, the terminal and the network side perform basic capability negotiation, and negotiate the type of the Convergence Sublayer (Convergence Sublayer, CS): 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 between the terminal and the network side. The access gateway on the network side sends an authentication start request to the terminal, 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 service QoS set (Ethernet QoS profile) according to the user subscription information and/or the Ethernet policy preset in the local network. The AAA server sends an access authorization message Access-Accept to the access gateway, and the access authorization message carries: Ethernet service QoS set (Ethemet QoS profile).

Wherein, the Ethernet service QoS set includes: Ethernet service QoS information and Ethernet classifier information. Ethernet service QoS information includes: maximum/minimum bandwidth, service class and user priority. The Ethernet classifier information includes: the source MAC address and the destination MAC address of the Ethernet service. The aforementioned Ethernet service QoS information may also include information such as: Committed Information Rate (CIR), CBS (Committed Burst Size), EIR (Exess Information Rate), EBS (Excess Burst Size), and CM (Color Mode).

The specific method of generating the Ethernet service QoS set in this step is: according to the user subscription information, the type and capability of the Ethernet service subscribed by the user are obtained, and according to the type and capability of the Ethernet service subscribed by the user, the Ethernet Obtain the user's Ethernet service QoS set in the network policy. Wherein, the preset Ethernet policy of the local network includes the source MAC address and the destination MAC address of the Ethernet service. The source MAC address and destination MAC address of the Ethernet service in this step may not be included in the Ethernet policy preset in the local network, and may be brought by the access gateway to the AAA server in the access authentication request message, without affecting the local network. realization of the invention.

In this step, the Ethernet service QoS set can also be generated only according to the subscription information of the user, or the Ethernet service QoS set can be generated only according to the preset Ethernet policy of the local network, which does not affect the realization 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 of this step is: map the Ethernet service QoS information into the QoS information carried by the access network, and the QoS information carried by the access network includes: the bearer identifier of the access network, the maximum/minimum bandwidth, time delay, jitter, Transfer type and user priority etc. The anchor data path entity (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.

Assuming that the data channel type of the current access network is a virtual local area network (VLAN), the ADPF maps out the VLAN identifier according to the priority information of the user. In this step, the Ethernet service QoS information is mapped into VLAN QoS information, and the above-mentioned VLAN QoS information includes: VLAN identification, maximum/minimum bandwidth and user priority etc.

Step 305, the access gateway establishes the access network bearer to the base station according to the QoS information and classifier information of the access network bearer.

In this step, the access gateway first sends a resource reservation request to the base station to request the establishment of an access network bearer for transmitting Ethernet service data. The resource reservation request includes: QoS information carried by the access network and classifier information.

If the current Ethernet service type is VLAN, the connection established in this step is based on VLAN.

Step 306, the base station maps the QoS information carried by the access network to the QoS information of the air interface connection, and establishes a classifier for the air interface connection according to the classifier information carried by the access network. The classifier for the air interface connection includes: source MAC address and destination MAC address address.

Step 307, the base station establishes an air interface connection to the terminal according to the QoS information and classifier information of the air interface connection.

Referring to FIG. 4, Embodiment 2 of the present invention provides a method for establishing an Ethernet service. When the terminal accesses the network, the method establishes an access network bearer and an air interface connection suitable for transmitting Ethernet services. The method includes:

Step 401-step 402 are the same as step 301-step 302.

Step 403, after the AAA server authenticates the user successfully, it sends an access authorization message Access-Accept to the access gateway. In the access authorization message, the Ethernet service QoS set can be carried. The Ethernet service QoS set in this step is the same as the step Same as in 303.

In step 404, the access gateway, as the policy enforcement point PCEF, sends an authorization request message to the PCRF to request further authorization in the PCRF.

Wherein, if the access authorization message in step 403 carries the Ethernet service QoS set, before step 404, the terminal identifier, the Ethernet service QoS set and classifier information may be obtained. If the PCRF has allocated an access network bearer identifier and/or established an access network bearer for the terminal before this step, at this time, the authorization request message sent by the access gateway to the PCRF in this step may include: Ethernet classification device information and access network bearer information including the access network bearer identifier. The authorization request message may also include: an Ethernet service QoS set for reference by the PCRF. Wherein the Ethernet classifier information includes: the source MAC address and the destination MAC address of the Ethernet service, the source MAC address and the destination MAC address can be obtained from the Ethernet service QoS set, or the access gateway can communicate with the terminal Acquisition in the information exchange performed on the network side does not affect the realization of the present invention.

If in step 403, the AAA server sends the access authorization message carrying the Ethernet service QoS set to the access gateway, in this step, the access network bearer can be established according to the Ethernet service QoS set, and in the subsequent step, the message containing the Ethernet service QoS set is received from the PCRF. When the network service QoS information and the PCC rules of the Ethernet classifier information are modified, the established access network bearer is modified according to the Ethernet service QoS information, which does not affect the realization of the present invention.

Step 405, PCRF acquires user subscription information from the user subscription database according to the user identifier. The user subscription database can be located in the AAA server or PCRF or other user databases.

This step is specifically: the PCRF sends a subscription information request message to the user subscription database, the subscription information request message carries a user identifier, the user subscription database obtains the user's subscription information according to the user identifier, and provides the PCRF with the user's subscription information.

Step 406, PCRF generates PCC rules for Ethernet services according to at least one of the user's subscription information, Ethernet policies preset in the local network, and authorization request messages sent by the access gateway. The PCC rules for Ethernet services include: Network service QoS information, Ethernet classifier information and billing information.

Among them, the Ethernet service QoS information includes: user priority, maximum/minimum bandwidth, and service level; the Ethernet classifier includes: information such as Ethernet service source MAC address and destination MAC address (if the access network bearer information is obtained from the access network If the inbound data channel uses VLAN, the Ethernet classifier also includes VLAN IDs such as VLAN ID and VLAN Tag).

There are several ways to implement this step:

The first way is: the PCRF only obtains the source MAC address and the destination MAC address of the Ethernet service QoS information and the Ethernet service according to the user subscription information, so as to generate PCC rules including the Ethernet service QoS information and the Ethernet classifier information; The user subscription information may include: Ethernet service QoS information, source MAC address and destination MAC address of the Ethernet service, and other information.
