Description

Method and system for managing home gateway related parameters in GPON system

Technical field

The present invention relates to a Gigabit-Capable Passive Optical Network (GPON) technology in the field of communications, and in particular to a method and system for managing a Home Gateway (HGW) related parameter in a GPON system.

Background technique

Among various fiber-based access technologies, GPON is favored by many large international operators due to its high bandwidth and high split ratio. The GPON-based Fiber To The Home (FTTH) solution has become the mainstream of all countries. Carrier's broadband solution.

Optical Network Unit (ONU) or Optical Network Terminal (ΟΝΤ) is used as an access terminal for GPON FTTH, in addition to providing traditional TRIPLEPLAY services (voice, data, video). The trend toward evolving home gateways. In this scenario, ONU and ONT act as gateway devices for connecting home local area network (LAN) and wide area network (WAN), and there are many necessary parameters to configure and manage. Due to the decentralized nature of FTTH terminals, remote maintenance management becomes a necessary means of network operation.

The OMCI management mechanism of the ITU-T G.984.4 specification is a passive optical network ONU or ONT remote management interface commonly used in the industry. That is, the management of ONU or ONT is completely through Optical Line Terminal (OLT) and ONU. The ONU Management and Control Channel (OMCC) is completed, and the Network Management System (NMS) and the OLT communicate through the Simple Network Management Protocol (SNMP). The NMS sends the commands and performance queries of the OLT and the ONU/ONT to the OLT through SNMP. The OLT sends the OLT to the ONT through the OMCI. The OMCI management architecture is shown in Figure 1.

The principle of OMCI is to configure a series of device management entities (MEs) to implement the configuration and management functions of the data channels of GPON ONU/ONT devices. The disadvantage is that there is no standard home gateway function management entity. , so can't be on the home gateway Various parameters related to the function are configured. In order to overcome the difficulty that the OMCI management mode cannot be remotely configured and managed when the GPON terminal device is used as a home gateway application, the current common method in the industry is to add a basis based on the ONU Management and Control Interface (OMCI) management architecture. The CWMP (CPE WAN Management Protocol, referred to as TR069) protocol is managed. The Auto-Configuration Server (ACS) is deployed on the network. The GPON ONU or the home gateway attributes are configured and managed remotely through the TR069 protocol. The TR069/OMCI hybrid management architecture is shown in Figure 2. The disadvantage is that two sets of management systems need to coexist, which increases the cost and complexity of network management.

Step 300: During the configuration data synchronization process of the OLT, the ONU/ONT starts running according to the set parameters.

Step 400: When the OLT needs to query the setting of the HGW management entity of the ONU/ONT, use the Get method of the G.984.4 protocol specification to request the current parameter value of the HGW management entity, and the ONU/ONT responds to the query command by using the Get response message.

Step 500: When the OLT needs to modify the configuration of the home gateway function data of the remote ONU/ONT, use the Set method of the G.984.4 protocol specification to reset the attribute values of the HGW ME of the ONU/ONT, and the ONU/ONT passes the feedback of the Set response message. Set the result, if the setting is successful, start running according to the newly set parameters.
