Description

PPPoE method for implementing dialing control and client front device

The present invention relates to an Asymmetric Digital Subscriber Line (ADSL) broadband service, and more particularly to a PPPoE (PPPoE, PPP over Ethernet) method for implementing dialing control and a client front device. Background technique

At present, most of the commercial broadband that has been widely used is mainly ADSL, and there are a large number of ADSL users in various countries around the world. On the basis of the ADSL Internet access, the authentication mode used by most of the accounting users is PPPoE. The PPPoE authentication and user charging are implemented. The PPPoE method has the following advantages:

(1) High security. In the PPPoE session, the application of the Password Authentication Protocol (PAP) or the Challenge-Handshake Authentication Protocol (CHP) for each process overcomes the common problems in the bridging mechanism. Security breach.

(2) Flexible payment methods. PPPoE charges for each connection process, and the Network Service Provider (NSP) or Network Access Provider (NAP) can charge for the length of the process or a minimum access fee.

(3) A wide range of CPEs are supported. In a PPPoE session, for a client-side device (CPE) that cannot run PPPoE, or a CPE that cannot support Point-to-Point Protocol (PPP, Point to Point Protrol), since the PPPoE method uses a bridge-based PPP protocol, it is Will not be affected.

(4) Support for multiple processes. The PPPoE protocol allows one PC to access multiple destinations at the same time, that is, there can be multiple processes on each PVC. (5) User authentication method is flexible. The NSP can control each user using the standard RADIUS (Remote Authentication Dial In User Service) protocol, such as setting idle or timeout.

(6) Simple configuration: The PPPoE client configuration is very simple. The DSL (Digital Subscriber Line) modem at the user does not need any special configuration.

(7) Good compatibility. The PPPoE protocol is compatible with all current DSL MODEM and Digital Subscriber Loop Access Multiplexers (DSLAMs).

Among the advantages of the above PPPoE method, the most important one is that the payment method is flexible, and can be charged according to the duration (ie, the time charge), and can also be charged in various ways such as traffic charging and minimum access fee charging. Most operators choose to use PPPoE to provide users with Internet access.

At present, most operators use time-based charging. Timing charges can effectively utilize resources and limit users. Because users who use the minimum access accounting will not disconnect after using the Internet access function, the IP address will be disconnected. Occupied, reduces the efficiency of operations, and releases IP due to connections. Figure 1 shows the system for dialing in PPPoE mode. As shown in Figure 1, it includes the client, CPE, and server.

However, there are some problems with the timing charge. When some users do not use and forget to close the CPE, PPPoE is still online. At this time, the billing is still made, and the user does not know this, causing direct complaints from the user and the operator. Therefore, there is a need for a technical way to achieve the automatic disconnection of the connection when the user does not use the connection, so as to prevent the occurrence of wasted billing. It can be extended to the CPE's own access network and network side devices to access the CPE's networking and disconnection automation. Summary of the invention

The main purpose of the present invention is to provide a PPPoE method for implementing dialing control and a client front device, which can ensure that the PPPoE connection is activated and deactivated according to the requirements of the operator and the user. Open, to achieve business intelligence. Ensure that when the user uses the CPE in the routing mode, the PPPoE is offline when the Internet is not connected but the gateway is not closed, interrupting the accounting, avoiding unnecessary loss of the user, helping the operator to recover the idle IP address, thereby improving the network utilization. rate.

In order to achieve the above object, the technical solution of the present invention is achieved as follows:

After the CPE receives the packet request, it triggers the dialing. It also includes:

After the dialup is successful, the CPE determines that the packet has not been received within the preset time and requests to disconnect the dial-up connection. The request is from a UE on the LAN side, or from the CPE local.

The CPE determines that the packet is not received within the preset time, and the request to disconnect the dial-up connection includes: the CPE detects the packet from the LAN side, and determines whether the packet exists on the LAN side, if the memory is in the preset time. At, continue to keep the current dial-up connection valid;

If it does not exist within the preset time, the CPE requests to disconnect the current dial-up connection.

After the dialing is successful, the method further includes:

If the CPE determines to receive the message from the WAN side within a preset time, the current dial-up connection is maintained;

If the CPE determines that the message from the WAN side is not received within the preset time, the current dial-up connection is disconnected.

FIG. 2 is a flowchart of a method for implementing dialing in a PPPoE manner according to the present invention. As shown in FIG. 2, the following steps are included:

Step 200: The CPE triggers the dialing after receiving the message request.

In this step, the message request may be from the user side of the LAN side, or may be from the CPE local (CPE application layer). The specific implementation of this step belongs to the prior art and will not be described in detail herein.

Step 201: After the dialing is successful, the CPE determines that the packet is not received within the preset time, and requests to disconnect the dial-up connection.

In this step, after the dialup is successful, the CPE detects the packet on the LAN side and determines whether there is a packet on the LAN side. If it exists within the preset time, the user still uses the current dial-up connection to continue to maintain the current dial-up. The connection is valid;

If there is no packet from the LAN side within the preset time, indicating that the user is not using the current dial-up connection and the CPE is not closed, the PPPoE is still online. At this time, the CPE requests to disconnect the current dial-up connection. By the method of the invention, when the user does not use the connection or the CPE does not access the network itself, the connection can be automatically disconnected, thereby preventing the phenomenon that the charging is wasted.

The method of the present invention further includes: after the dialing is successful, if the CPE determines to receive the message from the WAN side within the preset time, the current dial-up connection is maintained; if within a preset time, the CPE determines that the WAN side is not received. The message disconnects the current dial-up connection. By detecting the WAN side message, the method of the present invention extends to realize automatic control of the dial-up connection and dial-down of the network side device accessing the CPE.

Through the method of the invention, the PPPoE connection is ensured to be activated and disconnected according to the requirements of the operator and the user, and the business is intelligent. It ensures that when the user uses the CPE in the routing mode, the PPPoE is also offline when there is no Internet access but the gateway is not closed, thus interrupting the charging, avoiding unnecessary loss of the user, and helping the operator to reclaim the idle IP. The address, which improves the utilization of the network. FIG. 3 is a schematic structural diagram of a CPE in a system for implementing dialing in a PPPoE mode according to the present invention. As shown in FIG. 3, the position and function of the CPE in the system are the same as those in the prior art. The present invention adds a judging module to the CPE, and the judging module It is set in the CPE interface module and is connected to the existing CPE dialing module. After the dialing is successful, it is determined whether the packet is received within the preset time, and when the packet is not received, the CPE dialing module sends a request to disconnect. The notification of the dial-up connection. At this time, the CPE interface refers to the LAN-side interface, that is, the brO interface. The determining module is further configured to determine that the packet is received within the preset time, and send a notification to the CPE dialing module to continue to keep the current dialing connection valid.

The determining module is further configured to: after receiving the successful dialing, determine whether the packet from the WAN side is received within the preset time, and send a notification to the CPE dialing module to maintain the current dialing connection when the receiving is determined; when it is determined not to be received Send a notification to the CPE dial-up module to disconnect the current dial-up connection. The CPE interface refers to the WAN-side interface.

The following describes an embodiment of the present invention in a positioning service environment.

The first embodiment mainly focuses on user-side access, and points out a user access network establishment process, and a process in which the user does not access the network to disconnect the network. The PC accessed by the LAN side triggers and disconnects the dial by sending a text request to the WAN side, as shown in Figures 4 and 5, respectively.

The detailed description of the LAN side trigger dialing is shown in Figure 4, including the following steps:

Step 400: When the LAN side device of the CPE needs to access the Internet, send an Internet request to the WAN side.

Step 401: The CPE receives a request from the LAN side to the WAN side on the LAN side interface, that is, the brO interface, to notify the CPE dialing module to perform a dialing operation.

Step 402: The CPE dialing module initiates a PPPoE dialing request to the WAN side server (Brs).

Step 403: The server on the WAN side responds to the dialing request of the CPE, and allocates an IP address for accessing the Internet.

Step 404: The CPE obtains the IP address of the Internet and forwards the packet on the LAN side to the WAN side. Step 405: After receiving the request for access, the WAN side server returns the accessed content to the LAN side device.

Step 406: The CPE internal message is transmitted to the brO interface.

Step 407: The CPE forwards the requested content to the LAN side device to implement the online service. The detailed implementation of LAN disconnection dialing is as shown in Figure 5. When the LAN side client PC is offline and no longer sends any message to the CPE, the following steps are included:

Step 500: When the brO interface of the CPE has not received the request message sent by the LAN side to the WAN side for a preset time, it sends a notification to the CPE dialing module requesting to disconnect the dial-up connection.

In this step, the time period can be set by using a timer. The timer duration of the timer is a preset time length. When the timer expires, the request packet sent by the LAN side to the WAN side is not received. Indicates that the request message sent by the LAN side to the WAN side has not been received within the preset time. It should be noted that, before receiving the request message sent by the LAN side to the WAN side before the timer expires, the timer is reset after the CPE dialing module is notified to dial the number.

Step 501: The CPE dialup module receives the notification, finds that there is no device accessing the Internet, sends a disconnect request to the WAN side server, releases the IP, and disconnects the network.

Step 502: Network access is interrupted after disconnection.

The second embodiment is mainly directed to network access of the device itself, such as SNTP device timing, applications, dialing and disconnection when accessing the network and not using the network. The CPE sends a request to the WAN side to trigger and disconnect the dialing, as shown in Figure 6 and Figure 7, respectively.

The specific implementation of the CPE local "^ text trigger" is shown in Figure 6, including the following steps:

Step 600: The CPE internal application layer needs to access the WAN side service and send a request message to the WAN side.

Step 601: The CPE dialing module receives the request from the CPE application layer to the WAN side, triggers dialing, and initiates PPPoE dialing to the WAN side. Step 602: The WAN side server responds to the CPE dialing request and allocates an IP address for accessing the Internet.

Step 603: After obtaining the IP address of the Internet access, the CPE forwards the packet to the WAN side.

Step 604: The WAN side server returns the accessed content to the CPE after receiving the request for access. Step 605: The CPE receives the reply packet, and the access succeeds.

As shown in Figure 7, when the CPE application layer does not send any packets, the following steps are included:

Step 700: If no packet is found within the preset time, send a disconnect request to the server on the WAN side, release the IP, and disconnect the network.

Step 701: Network access is interrupted after disconnection.

The third embodiment is mainly directed to access to devices, such as remote management applications, dial-up hold and disconnect procedures when a network is required and when the network is not needed. Messages sent by the WAN side remain connected and disconnected, as shown in Figure 8 and Figure 9, respectively.

The specific implementation of the WAN-side packet connection is as follows: Step 800: After the CPE has successfully dialed the connection, the WAN side sends a request packet for accessing the device to the WAN interface of the CPE.

Step 801: After receiving the WAN side access request, the CPE sends a notification to the CPE dialing module to maintain the PPPoE dial-up connection.

Step 802: After receiving the notification, the CPE dialing module performs a dial hold operation and resets the timer for detecting the packet.

Step 803: The WAN side server returns information, and the link is unblocked.

Step 804: In response to the access request on the WAN side, the reply is sent, and the access is successful.

The specific implementation of the WAN side is shown in Figure 9. When the WAN no longer sends any text, the following steps are included:

Step 900: The CPE finds that the WAN-free party accesses the CPE packet to the CPE within the preset time. The dialing module sends a notification of the disconnect request.

Step 901: The CPE dialing module sends a disconnect request to the server on the WAN side, releases the IP, and disconnects the network.

Step 902: Network access is interrupted after disconnection.

In the embodiment of the present invention, the situation of triggering the dialing and the situation of disconnecting the dialing are pointed out, and the time delay can be used to control, that is, the timeout period is set, and the timer is used, if there is no message in the time, Disconnect, if there is a message during this time, keep the connection. Through the time control method, the disconnection and dialing control are conveniently and simply implemented, which not only satisfies the requirements of the user for accessing the Internet, but also satisfies the operator's control over the IP address and avoids unnecessary charging, and also solves the problem. The dial-up and disconnection scenarios when the device itself accesses the network and remotely access the device effectively improve the utilization and management of the IP address.

In the above example, the combined operation may also be performed according to specific requirements, and may be combined according to actual needs and provided with a timer configuration. For example, the configuration of the Internet user can be combined as follows: First, enable the LAN side trigger switch, then enable the timer configuration, detect the packet, determine the disconnection dial condition, and then turn off the local device packet trigger. Finally, close the WAN side. The message connection is maintained. After the appeal is configured, the dial-up can be automatically performed when the user accesses the network, and the disconnection is made when the user does not need to access the network. The CPE can't be triggered locally, which better meets the user's needs and usage environment.

For the carrier, the following combinations can be configured: First, the local ^ 艮 message is triggered, then the WAN side message connection is maintained, then the timer is started, the message is detected, the dialing condition is determined, and finally, the LAN side is closed. Trigger switch. After the appeal is configured, the operator can trigger the dial-up when the remote management is performed. When the TR069 remote management is used, the device cycle is set. When the packet is sent, the dial-up can be triggered for remote management. After the dial-up is successful, the WAN-side access is checked. Messages, dialing will not be disconnected during remote management. It helps the operators to manage the equipment and realize the effective recovery of IP addresses. In practical applications, the corresponding configuration items can be implemented according to the requirements of the use, and the control of the dial-up connection can be implemented to meet different requirements and different environments. The method provided by the present invention can be easily combined and implemented by a person skilled in the art, and will not be described in detail herein.
