Problems solved by technology

Since the rogue ONU does not work in its own time slot and occupies the uplink time slot of the normal ONU, the OLT cannot normally receive the uplink services sent by other ONUs, causing the normal ONU's services to be lost and offline

Embodiment Construction

[0112] The solutions of the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0113] see first Figure 1-A , Figure 1-A It is a schematic diagram of an example architecture of a PON system. Among them, the PON system includes an OLT (also called a central office) and an ONU (also called a user end), and optical passive devices such as optical fibers and passive optical splitters (Splitter) are only required to couple between the OLT and the ONU. Splitter can be referred to as a splitter for short.

[0114] Wherein, the OLT and the Splitter are coupled through a backbone optical fiber (Feeder), and the Feeder is also called a feeder segment. Splitters can couple multiple fibers together. Wherein, the Splitter and the ONU are coupled through a branch optical fiber (Drop), and the Drop is also called an attenuation section.

[0115] Wherein, the direction from the OLT to the ONU is ca...

Abstract

Embodiments of the present application provide an uplink resource authorization method, device, passive optical network, and computer-readable storage medium. A method for authorizing uplink resources, comprising: an optical line terminal obtains a converted uplink authorization message, the conversion parameters used in the conversion process include the physical identity of an optical network unit ONU; the optical line terminal sends the converted uplink authorization message An uplink grant message, where the uplink grant message carries an uplink resource grant indication of the optical network unit, and the uplink resource grant indication is used to indicate the uplink resource authorized to the optical network unit. The technical solution provided by the embodiment of the present application is beneficial to reduce the occurrence probability of the rogue ONU phenomenon, and further helps to improve the service operation stability of the PON system.

Description

technical field [0001] The present application relates to the technical field of optical communication, and in particular to an uplink resource authorization method, device, passive optical network, and computer-readable storage medium. Background technique [0002] Currently, there are many common access network broadband solutions for services, such as twisted pair access, coaxial cable access, and optical fiber access. Twisted pair and coaxial cable access technology can make full use of existing copper wire resources, and the project cost is low, but it is difficult to provide sufficient bandwidth for new services such as video on demand, two-way video conferencing, etc., and the transmission distance is limited, and the network coverage is small . The huge capacity and long-distance transmission of optical fiber determine that optical fiber access is a high-quality solution for broadband access. [0003] Telecommunications services are becoming more and more abundant,...
