Problems solved by technology

However, the ONU-ID, ALLOC-ID, and GEM-PORT-ID that can be supported by the MAC layer protocol of the existing TDM-PON system such as GPON are very limited, for example, it can only support up to 256 ONU-IDs (including broadcast IDs) , become the limit of large branches supporting more ONUs at the MAC layer than HPON technology

Abstract

Disclosed are a method, device and system for converting terminal device identifiers. The method includes: receiving the uplink data sent from a terminal device, wherein the control part of the uplink data includes the device identifier indicating the terminal device; obtaining an extended device identifier corresponding to the uplink data according to the bandwidth authorization information corresponding to the uplink data; determining that the device identifier included in the control part of the uplink data matches the extended device identifier; and replacing the device identifier included in the control part of the uplink data with the extended device identifier. The method, device and system for converting terminal device identifiers in the embodiments of the present invention can enable the media access control layer to support the large branching ratio passive optical network system by replacing the terminal device identifier, and can improve the system capacity without making any change to the optical network unit or terminal, lowering the system costs.

Description

technical field [0001] The present invention relates to the field of optical communication, in particular to a method, device and system for converting identifiers of terminal equipment in the field of optical communication. Background technique [0002] Gigabit Passive Optical Network (Gigabit Passive Optical Network, referred to as "GPON") is a point-to-multipoint (Point To Multi Point, referred to as "P2MP") optical fiber access network, which consists of optical lines on the office side Optical Line Terminal ("OLT" for short), optical network unit (Optical Network Unit, "ONU" for short) at the user side or ONT (Optical Network Terminal, "ONT" for short), and optical distribution network (Optical Distribution Network, referred to as "ODN"). A passive optical network (Passive Optical Network, “PON” for short) system mainly adopts a tree topology. [0003] In the PON system, the OLT not only provides a network-side interface, but also connects to one or more ODNs through ...
