Mode for carrying out the invention

The embodiment of the invention discloses a method, a device and a system for charging in a Wimax network to implement charging for an Ethernet-CS service.

In the network authentication and authentication process, the packet sent by the network access server (NAS) indicates that the supported charging type includes the Ethernet aggregation sub-layer number of the charging type, and then The Home Authentication Authorization and Accounting (HAAA) server returns an allowable access message to the NAS, and the message indicates the selected charging type, thereby completing the charging in the Wimax network. The problem of charging for the Ethernet-CS service cannot be solved in the prior art.

The specific embodiments of the embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

An embodiment of the present invention provides that, in the process of network authentication and authentication, the NAS indicates the type of charging it supports: IP session based charging, flow based charging, and media based access. Media Access Control (MAC) Session (MAC Session) Charging or the types of charging it supports are: Session-based charging, Flow-based charging, IP-based sub-layer IP-CS-based charging and MAC-based aggregation Sub-layer MAC-CS charging, in order to implement the charging method of the Wimax network, realizes charging for the Ethernet-CS service. FIG. 2 is a flowchart of a method for charging a Wimax network according to an embodiment of the present invention.

Step 201: The terminal MS sends an incoming network request message to the network access server NAS.

Step 202: The network access server NAS sends a request message to the HAAA server, where the request message includes an accounting type capability supported by the NAS, and the supported charging type capability includes at least charging of the Ethernet convergence sublayer data. The type of billing it supports The KTLPHW091034 capability may specifically be at least one of the following charges: IP session based charging, IP flow based charging, MA C session based charging or MAC flow based charging.

The supported charging type capability may specifically be: at least one of session charging and flow based charging, and at least one of IP-CS based charging and MAC-CS based charging.

Step 203: The HAAA server authenticates the user. After the authentication succeeds, the user sends an access permission message to the NAS, indicating that the user access is successful, and the access permission message indicates the selected charging type.

In the foregoing step 202, the NAS includes the supported charging type capability. The specific implementation manner of the NAS may be as follows: The charging type of the MAC session is added to the Wimax Capability in the request message sent by the NAS. The Wimax Capability field can be as shown in Figure 3. When the ID of the Type Value Length (TLV) field in Figure 3 is 2, it means that the accounting capability (Accounting Capabilities), when the value of Accounting Capabilities is 0x00, is not charged; when the value of Accounting Capabilities is 0x01 For accounting based on IP sessions; when the value of Accounting Capabilities is 0x02, it is based on flow accounting; when the value of Accounting Capabilities is 0x04, it is based on MAC session charging.

In the foregoing step 202, the NAS includes the charging type capability supported by the NAS, and the Accounting Capabilities can be defined as follows:

· 0x00 = No accounting. (Value is 0x00, no billing)

• 0x01 = Session-based accounting. (When the value is 0x01, based on session charging, this value is the default value of ASN)

• 0x02 = Flow-based accounting (flow-based billing when the value is 0x02)

• 0x04 = IP-CS supported (IP aggregation is supported when the value is 0x04)

· 0x08 = Eth-CS Supported (When 0x08, Ethernet aggregation is supported).

According to the above cell definition, it can represent IP session based charging, IP based flow charging, Ethernet (Eth) session charging, Eth based flow charging.

The method for implementing the Wimax network charging method according to an embodiment of the present invention may further include:

Step 204: The NAS generates a bill record correlator, and sends the bill record correlator to the HAAA server by using the billing request message. The bill record correlator includes a MAC address of the terminal MS, and the MAC address is used to identify the billing granularity of a MAC session.

The field definitions of the bill record correlator are shown in Table 1.

Table 1 Name - ,f ί Description Start Ψ

The Acct-Session-Id 44 is generated by the accounting client to match the start message, the intermediate message, and the end message. Unique to each pair of start/end message pairs.

Acct-Multi-Session-Id 50 This field defines the ID of an AAA session. The AAA 1 1 1 session ID is generated by AAA after successful authentication or re-authentication.

It is sent to the NAS through an access accept message.

PDFID 26/26 This field matches records generated from the same packet data stream. 0-1 0-1 0-1 The PDFID has CSN generated and remains unchanged for [1,4] [1,4] [1,4] throughout the transition process. KTLPHW091034

The MAC-address field is defined as shown in Table 2.

Table 2

The charging model for implementing the Wimax network charging method provided by the embodiment of the present invention can be represented by FIG. 4. The role of the bill record correlator is to link a bill with multiple segments to a user. The existing CDR record correlator only has an IP address. We need to add a MAC address to associate multiple MAC-session segment CDRs to the same user. The charging hierarchy diagram with different granularities is shown in Figure 4: A subscriber (subscriber) can have multiple subscriptions according to different network access indications (NAI); one subscription corresponds to one device-session (device-session) Each device session can correspond to one or more billing granular IP sessions (IP-sessions) according to the IP address; each billing granularity IP session can correspond to one or more billing granularity packet data streams according to the PDF ID. (PD-flow). Billing information collection is on two granular models of IP session (IP-session) and packet data flow (PD-flow). Each device session may also correspond to a billing granular MAC session according to the MAC address; each billing granularity MAC session may further correspond to one or more charging granularity packet data streams according to the PDF ID, where PD-f Low is the data flow for the Ethernet-CS service. Billing information collection is on the two granular models of MAC session and packet data flow.
