Abstract
The invention provides a method and a system for managing relevant parameters of a home gateway (HGW) in a GPON (Gigabit Passive Optical Network) system. The method comprises the following steps that: an optical network terminal with a home gateway function creates a case of a home gateway management entity and informs an optical line terminal that the optical network terminal has service capability of the home gateway through an OMCI (Ont Management And Control Interface); and after the optical line terminal receives the inform, the optical line terminal manages relevant parameters of the management entity of the home gateway through the OMCI. According to the method and the system disclosed by the invention, convenient maintenance and management for home gateway terminal equipment in the GPON system can be realized through an OMCI management interface and better real-time property is obtained; and compared with a traditional remote management scheme, an ACS (Adaptive Computer System) can be avoided, so that the complexity of a network management system and the cost for operation and maintenance of the network management system are reduced.
Description
Technical field
The present invention relates to (the Gigabit-Capable Passive Optical Network of gigabit passive optical network in the communications field; Be called for short GPON) technology; Particularly, the management method and the system that relate to home gateway in a kind of GPON system (Home Gateway is called for short HGW) relevant parameter.
Background technology
In various access technologies based on optical fiber, GPON since its high bandwidth and high splitting ratio favored by the large-scale operator in numerous worlds, based on GPON Fiber to the home (FTTH) solution also becomes various countries mainstream carrier's broadband solution.
Optical network unit (Optical Network Unit; Be called for short ONU) or ONT Optical Network Terminal (Optical Network Terminal; Be called for short ONT) as the access type terminal of GPON FTTH; Except traditional T RIPLEPLAY professional (voice, data, video) is provided, the trend of also oriented home gateway evolution.Under this scene, ONU and ONT have a lot of necessary parameter to be configured and to manage as the gateway device that is connected family's local network (LAN) and wide area network (WAN).Since the dispersed characteristic at FTTH terminal, the necessary means of remote maintenance management becoming network operation.
The ITU-T G.984.4 OMCI administrative mechanism of standard is EPON ONU or the ONT remote management interface that present industry is generally used; Promptly pass through optical line terminal (Optical Line Terminal fully for the management of ONU or ONT; Be called for short OLT) and ONU/ONT between management channels (ONU Management and Control Channel; Be called for short OMCC) accomplish, then communicate by letter between NMS (being called for short NMS) and the OLT through Simple Network Management Protocol (SNMP), NMS will unify to be dealt into OLT with SNMP to the order of OLT and ONU/ONT and performance queries etc.; OLT issues ONT through OMCI again, and the OMCI management framework is as shown in Figure 1.
The principle of OMCI is based on a series of equipment related management entity (Management Entity; Be called for short ME) be configured; Realization is to the configuration and administration feature of the data channel of GPON ONU/ONT equipment; Its shortcoming is not have standard home gateway functionalities management entity at present, so can not be configured the relevant various parameters of home gateway functionalities., the GPON terminal equipment can't Remote configuration manage this difficulty for overcoming the OMCI way to manage when using as home gateway; Current industry universal mode is at ONU management control interface (ONU Management and Control Interface; Abbreviation OMCI) increases based on CWMP (CPE WAN Management Protocol on the basis of management framework; Abbreviation TR069) way to manage of agreement is disposed Automatic Configuration Server (Auto-Configuration Server is called for short ACS) in network; Be configured and manage through the long-range home gateway attribute of TR069 agreement GPON ONU or ONT; TR069/OMCI mixed management framework is as shown in Figure 2, and its shortcoming is needs two cover management systems and deposits, increased network administration cost and complexity.
