Remote management method and system for VDSL terminal device

Abstract

The method is used in a system comprising: terminal management system, central office apparatus and VDSL terminal device. It comprises: configuring the management virtual local area network (VLAN) on the central office apparatus; configuring the management interface on the central office apparatus, and adding the management interface into VLAN; adding customer's port corresponding to the VDSL terminal device into the port list of VLAN; after VDSL terminal establishes a connection, the terminal management system makes far-end management for the VDSL terminal device via the management VLAN. The invention also provides a system thereof.

Description

technical field [0001] The present invention relates to the field of broadband access technology, in particular to a method and system for remote management of very high speed digital subscriber line (VeryHigh Data Rate Digital Subscriber Line, VDSL) terminal equipment. Background technique [0002] With the continuous development of broadband service networks, various broadband access technologies have increasingly shown their important role in the "last mile" transmission bottleneck problem, and the digital subscriber line (Digital Subscriber Line, DSL) technology has undergone continuous development , has considerable advantages in terms of deployment convenience and performance-cost ratio, and has become the main broadband access method in the world. DSL technology is mainly divided into Asymmetric Digital Subscriber Line (ADSL), Single High Bit Rate Digital Subscriber Line (SHDSL), Very High Speed ​​Digital Subscriber Line (VDSL), etc. [0003] With the maturity of tec...

Problems solved by technology

[0010] In the past one or two years, VDSL technology has attracted wide attention from chip suppliers, equipment manufacturers and network operators due to its bidirectional symmetry and high bandwidth in short distances, as well as the compatibility of VDSL2 and ADSL2+. The progress is fast, and the scope of application is also constantly being promoted, but its corresponding broadband operation and maintenance technology has not been developed correspondingly like ADSL. After the number of users increases, it will face many problems in operation and maintenance just like ADSL. Therefore, There is an urgent need to keep up with a series of operation and maintenance technologies such as remote terminal management and version upgrades

[0011] As mentioned above, the ADSL remote terminal management technology includes the technical solution based on the PVC management channel and the technical solution based on the EOC management channel. The technical solution is only applicable to ADSL (ATM Over ADSL) based on ATM transmission mode or SHDSL (ATM Over SHDSL) based on ATM transmission mode, but not to VDSL (Ethernet Over VDSL) technology based on Ethernet. When the remote version is upgraded, it needs to use the service channel to realize it, which will affect the user's current business and cause certain problems to the user's actual use

However, if the technical solution based on the EOC management channel is used in the remote management of VDSL terminals, there are the following defects: because the EOC channel itself lacks a flow control mechanism, its actual transmission performance needs to be tested; As a management channel, EOC-based HDLC requires modem (Modem) chip-level support. In addition to software changes, it may also involve hardware chip changes. Existing compatibility issues have a greater impact on existing equipment, and it is difficult to implement on the entire network. It also needs to use the service channel to realize the remote version upgrade of the terminal, which will affect the current business of the user and cause certain problems to the actual use of the user

[0013] In summary, the existing remote management technology of VDSL terminal equipment obviously has inconvenience and defects in actual use, so it is necessary to improve it
