Digital subscriber line access multiplexer, optical network unit, optical line terminal and base station

Abstract

The embodiment of the invention relates to a digital subscriber line access multiplexer, which includes: a digital subscriber line interface unit used for processing a physical layer and a data link layer of the digital subscriber line, at least two access multiplexer units for virtual digital subscriber lines used for processing a message from the digital subscriber line by an analog digital subscriber line access multiplexer, a return interface unit used for receiving the message processed by the digital subscriber line access multiplexer unit, and transmitting the message from the fringe node or operator equipment to the virtual digital subscriber line access multiplexer unit for processing. The embodiment of the invention also relates to an optical network terminal, an optical link terminal and a base station. Therefore, the embodiment of the invention solves the sharing of AN by a plurality of NSP under the wholesale background, which realizes the independent management of the AN by the NSP, and can provide different protocols at the request of different SP and bring great flexibility of different NSP for the wholesale of NAP.

Description

technical field [0001] The embodiment of the present invention relates to the field of mobile communication, in particular to a digital subscriber line access multiplexer, an optical network unit, an optical line terminal and a base station. Background technique [0002] Such as figure 1 As shown, it is a structural diagram of an optical access network in the prior art. The optical access network (OpticalAccess Network, OAN) consists of a customer premise network (Customer Premises Network, CPN) 61, an access network (Access Network, AN) 62 and It consists of 63 service function points (Service Node Function). The main network elements of OAN (Optial Access Network) customer premises network and access network include: Adaptation Function (Adaptation Function, AF) 621, Optical Network Unit (Optical Network Unit, ONU) / Optical Network Terminal (Optical Network Terminal, ONT ) 622, an Optical Distribution Node (ODN) 623, and an Optical Line Termination (OLT) 624. Where T is ...

AI Technical Summary

Problems solved by technology

However, the existing access nodes are not designed for wholesale (Wholesale) requirements, so it is impossible to realize the sharing of multiple NSPs to ANs, and it is impossible to realize independent management of NSPs to ANs, and it is impossible to provide different protocols to meet the needs of different SPs. NAP Poor flexibility to wholesale to different NSPs
