Description

Method and system for realizing automatic work order in EPON

The present invention relates to a method and system for implementing an automated work order in an EPON. Background technique

The Ethernet Passive Optical Network (EPON) is a new type of fiber access network technology that uses point-to-multipoint architecture and passive optical fiber transmission to provide multiple services over Ethernet. It uses PON technology at the physical layer, Ethernet protocol at the link layer, and Ethernet access using the PON topology. Therefore, it combines the advantages of PON technology and Ethernet technology: low cost; high bandwidth; strong scalability, flexible and fast service reorganization; compatibility with existing Ethernet; convenient management and so on.

EPON consists of a fiber-optic line termination, an optical distribution network (ODN), and an optical network unit, using a tree topology. Data and voice are transmitted using upstream 1 310 nm and downstream 1 490 nm wavelengths, while CATV services are carried at 1 550 nm wavelength. The OLT is placed at the central office, and the connection of control and control channels is provided, with real-time monitoring, management, and maintenance functions. The ONU is placed on the user side, and the OLT and the ONU are connected by a passive optical distribution network in a 1:16/1:32/1:64 mode.

The EPON network uses a point-to-point topology to replace the point-to-point structure, which greatly saves fiber usage and management costs. Passive network equipment replaces repeaters, amplifiers, and lasers in traditional ATM/SONET broadband access systems, reducing the number of lasers required at the central office, and the OLT is shared by many ONU users. In addition, EPON utilizes Ethernet technology and uses standard Ethernet frames to carry current mainstream services and IP services without any conversion. Therefore, EPON is very simple, efficient, low construction cost and low maintenance cost, and is most suitable for broadband access network needs.

In EPON, the process of transmitting data from the OLT to multiple ONUs is transmitted by means of data broadcasting. The data is broadcasted downstream from the OLT to multiple ONUs in the form of variable length packets. According to the IEEE 802.3 protocol, the maximum packet size is 1 518 bytes. Each packet carries an EPON header that uniquely identifies whether the packet is addressed to ONU-l, ONU-2, or ONU-3. It can also be identified as a broadcast packet sent to all ONUs or to a specific ONU group (multicast packet). When the data arrives at the ONU, the ONU receives and identifies the packet sent to it by address matching, and discards the packet sent to other ONUs.

With the rapid development of Internet construction, the number of Internet users and the application services of various networks have grown rapidly. In order to comply with the rapid development of the Internet and meet the urgent demand for broadband data services, all telecom operators are building a broadband data network. As the business volume increases, a large number of work orders per day require network maintenance center work. The handling of personnel, coupled with the front office staff to perform device port operations, makes the back-end network maintenance center staff work heavy. Summary of the invention

In view of this, an object of the present invention is to provide a method for reducing the workload of a network maintenance center staff and improving the efficiency of service opening.

In order to achieve the above object, the present invention provides a method for implementing an automatic work order in an EPON, comprising the following steps:

OLT accessing the network: When the user completes the OLT data configuration on the broadband access network management system ANM, the OLT access button is clicked. At this time, the ANM sends a query command to query the OLT for the OLT access information, and the ANM receives the network return from the OLT. The information is reported to the resource management system RMS, and the RMS returns an OLT incoming response message to the ANM, and the ANM informs the OLT of the network access result of the OLT;

ONU power-on automatic authorization/configuration procedure: When the EPON interface disk EC2 detects the ONU registration information, if the ONU is authorized, the ONU is set according to the configuration in the ROM. If the ONU is not authorized, the EC2 reports the ONU information to the ONU. The main control panel GSWC; GSWC checks whether the PON port is full. If it is full, it will generate a prompt alarm. If it is not full, check whether the slot authorization is full. If the slot authorization is full, a prompt alarm will be generated. If it is not full, the GSWC will be automatic. Authorize the ONU and deliver the configuration package to the EC2. The EC2 authorizes the ONU. The GSWC configures the temporary VLAN. All the ports of the ONU join the 3998 temporary Internet access VLAN in the UNTAG mode, and deliver the configuration package to the EC2. The EC2 performs the corresponding port configuration.

Disassemble step: The RMS delivers the teardown command message to the ANM, and the ANM sends the teardown command message to the OLT. After receiving the HG teardown command, the OLT returns an error message if the parameter is invalid. If the parameter is valid, configure the ONU and send a configuration command to EC2 to clear the HG in-position information and the network success message. EC2 receives the configuration command and then modifies it. Related configuration, clear HG in-position information and network success message.

Preferably, the method further comprises:

Voice port deactivation step: The RMS sends a voice port deactivation message to the ANM. The ANM sends the message to the OLT. The OLT responds to the voice port to deactivate the confirmation message to the ANM, and then the ANM responds to the message to the RMS.

Preferably, the method further comprises:

ONU port connection device change processing steps:

(1) Check if the ONU port is LINKUP;

(2) If no, then, yes, the type of the downlink device is detected. If HG mac is detected, it is considered to be HG; if polling 3 times does not detect HG mac, it is considered to be PC;

(13) When the resource system is enabled, the device needs to periodically poll the ONUs that have not completed the automatic authorization in the system, and perform automatic authorization to initiate the network access operation.

( 14) When the resource system is enabled, the AN5116-02 device needs to periodically poll the home gateway that is not in the network and initiate network access.

The invention will be further described below in conjunction with the accompanying drawings.

Figure 1 shows the flow chart of the OLT network access system. When the user completes the EPON central office equipment AN5116-02 (OLT device) data configuration on the broadband access network management system ANM, the OLT access button will be clicked, and the ANM will issue the check. The query command queries the OLT for the OLT to access the network information. After receiving the network information returned by the OLT, the ANM reports the information to the resource management system. The management system, the resource management system RMS returns an OLT incoming response message to the ANM, and the ANM informs the OLT of the network access result of the OLT. There are three points to note here: 1.0 LT access to the network is only performed when the OLT is first opened or later uplink expansion; 2. If the ANM reports that the OLT has failed to access the network three times, the response sent to the OLT is failed. The OLT generates an emergency alarm; 3. The counter C1 is implemented on the ANM, and the OLT does not need to care.

When the OLT processes the incoming network query, the OLT enters the network access information TRAP whenever the OLT receives the ANM command message. When the OLT receives the ANM response, if the network access is successful, the OLT access network flag is set to 1, and the OLT network access information TRAP is terminated. The OLT network access failure alarm is sent and sent to the EC2. Otherwise, if the network access is unsuccessful, the OLT generates an emergency alarm and ends the OLT. Network access information TRAP.

Figure 2 is the automatic authorization/configuration process of the ONU power-on. When the ONU registration information is detected by the EPON interface disk EC2, if the ONU is authorized, the ONU is set according to the configuration in the ROM. If the ONU is not authorized, the EC2 reports The ONU information is sent to the main control panel GSWC (including the MAC address, type); GSWC checks whether the PON port is full. If it is full, it will generate a prompt alarm. If it is not full, check whether the slot authorization is full. If the slot authorization is full A notification alarm is generated. When not full, the GSW automatically authorizes the ONU and sends the configuration packet to the EC2. The EC2 authorizes the ONU. The GSWC configures the temporary VLAN. All the ports of the ONU join the 3998 temporary Internet access VLAN in the UNTAG mode, and deliver the configuration package to the EC2. , EC2 performs the corresponding port configuration.

Figure 3 is a flow chart of the ONU network access system. After the OLT completes the ONU automatic authorization/configuration, the ONU reports the ONU network access information to the ANM. The ANM sends the ONU network access information to the RMS. After receiving the information, the RMS sends the ONU configuration information to the ANM. The ANM sends the configuration information to the OLT. The OLT returns the configuration execution result to the ANM, and the ANM sends the configuration execution result to the RMS. Note that: (1) The ONU can enter the network only after the OLT is successfully connected to the network. (2) The OLT needs to know whether the newly powered ONU has completed the network access to avoid repeated network access. (3) If the AMN reports ONU access to the network three times, it is unsuccessful. The response sent to the OLT is a failure. At this time, the OLT generates an emergency alarm. If the network is successful, the RMS sends the ONU configuration information to the ANM. The ANM sends the received ONU configuration information to the OLT. (4) The counter C2 is in the ANM. On the implementation, the OLT does not need to care.

The ONU network access information is reported to the ANM by the GSWC in the TRAP mode after the automatic authorization and temporary configuration of the ONU is completed. The main process is as follows:

1. After the automatic configuration of the ONU is completed, the GSWC initiates the ONU network access information TRAP;

2. If the ONU configuration failure message is received, an emergency alarm is generated, and the return fails. The ONU network access information TRAP is terminated. If the ONU configuration success message is received, the parameters configured by the ONU are checked. The parameters of the ONU configuration include the ONU. Physical location, ONU type, etc.

3. If the parameter is invalid, the return fails, and the ONU access information trap is ended. 4. If the parameters are valid, the GSWC configures the port according to the ONU type. All the ports are added to the Internet access VLANs in the UNTAG mode. The voice parameters are configured (the configuration is not required to be sent to the AC16), and the configuration packets are sent to the EC2.

After receiving the configuration packet, the EC2 configures the port according to the following rules. BP: Configures the port according to the ONU type. All the ports are added to their respective access VLANs in the UNTAG mode to configure voice parameters.

6. The GSWC responds to the ANM with the configuration success. The ONU network access flag is set to 1. The ONU network access information TRAP is sent to the EC2.

Figure 4 is a flow chart of the HG network entry system. After the OLT device completes the ONU network access process, if the ONU port downlink device is detected as the home gateway HG, the HG registration process is initiated. After receiving the HG information, the ANM reports the resource management system. The resource management system communicates with the access control server ACS and configures the HG, and finally returns the operation result.

When the HG network access information is reported, the EC2 detects that the ONU port is connected to the HG. If the HG is connected to the network, the ECG reports the HG network information. The GSW reports the HG information in the TRAP mode. The process of the OLT processing the HG incoming network response is as follows: The OLT receives the ANM response. If the network access is successful, the HG network access information TRAP is terminated, and the network access result is also sent to the EC2, and the EC2 performs corresponding configuration. If the network access fails, the HG network access information TRAP is terminated. The OLT generates an emergency alert.

Figure 5 is a flow chart of the voice port activation/deactivation system. The RMS sends a voice port activation message to the ANM. The ANM sends the message to the OLT. The OLT responds to the voice port activation confirmation message to the ANM, and then the ANM responds to the message to the RMS. The deactivation process is similar to the activation process.

Figure 6 is a flow chart of the teardown system. The HG teardown process is taken as an example to describe the teardown process: The RMS delivers the teardown command message to the ANM, the ANM sends the teardown command message to the OLT, and the OLT receives the HG teardown command. After the parameter is invalid, the error message is returned. If the parameter is valid, the ONU is configured accordingly and sends a configuration command to EC2 to clear the HG in-position information and the network access success message. After receiving the configuration command, EC2 modifies the configuration and clears the HG in place. Information and success messages.

Figure 7 shows the change process of the ONU port connection device:

1. Check whether the ONU port is LINKUP.

2. If no, then, yes, the type of the connected device is detected. If HG mac is detected, it is considered to be HG; if polling 3 times does not detect HG mac, it is considered to be PC;

3. Check whether the device type connected to the ONU port changes, otherwise, the connection device change processing flow is ended; if yes, step 4 is performed; 4. Report the type change information to the GSWC;

5. If the PC is changed to HG, Bay IJ GSWC will add the FTTB (Fiber To The Building fiber to the building) port to the Internet VLAN, IPTV VLAN, SIP phone VLAN, 3999 VLAN, ONU automatic TAG mode to join 3998VLAN, FTTH (Fiber) To The Home, PG to PC is changed to transparent transmission; if HG is changed to PC, GSWC adds the port to the Internet VLAN in UNTAG mode;

6. The GSWC performs related configuration and sends the configuration information to EC2.

7. EC2 will modify it after receiving the configuration information.

When the ONU is cut (that is, the ONU is replaced), the OLT receives the ONU replacement command from the NMS, and GSWC establishes the correspondence between the new and old ONU mac addresses in the data structure.

Figure 8 shows the ONU replacement process:

1. EC2 detects the new ONU registration and reports the automatic authorization request;

2. Determine whether the ONU is the ONU to be replaced, if not, enter the automatic authorization process, end the replacement process, and if yes, perform step 3;

3. Determine whether the new ONU is the same as the original ONU type. If not, the ONU type mismatch prompt alarm is generated, and the replacement process is ended. If yes, step 4 is performed;

4. The GSWC sends the original ONU's de-authorization command to the EC2, and the original configuration is mapped to the new ONU. The backup ONU mac address parameter is cleared, and the configuration is sent to the EC2. The ONU replacement success prompt alarm is generated, and the ONU replacement success event is generated.

5. EC2 performs related configuration.

Figure 9 is a schematic view showing the structure of the system of the present invention. The RMS of the resource management system is connected to the home gateway control server HG ACS. The HG ACS is used to control and manage the home gateway HG, and is connected to the corresponding Internet and media gateway controller MGC through the metropolitan area network. The OLT is connected by the optical splitter ODN. ONUs, ONUs are connected to VOIP, PC, IPTV, etc., or are connected to them through HG.
