A method and device for sharing a passive optical network

Abstract

The embodiments of the invention relate to the technical field of communications, and disclose a method and apparatus for sharing a passive optical network, for enhancing common building and sharing of a network, decreasing building cost and operation cost, reducing information security risks and improving network reliability. The method comprises: a stationed place network management system determining a service provider corresponding to an ONU, and adding the service provider identification of the service provider corresponding to the ONU in a communication protocol stack between an OLT and an ONU; the stationed place network management system establishing a first mapping relation and a second mapping relation, wherein the first mapping relation is a mapping relation between the service provider identification and an uplink port group, the second mapping relation is a mapping relation between the service provider identification and the ONU, and the service provider identification is used for distinguishing service provider; and the stationed place network management system, according to the first mapping relation and the second mapping relation, performing data interaction between the service provider and the ONU by use of the communication protocol stack between the OLT and the ONU. The method and apparatus for sharing the passive optical network are applied to a scene in which the passive optical network is shared.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for sharing a passive optical network. Background technique [0002] With the rapid development of information and communication technology represented by Internet (Internet) and the continuous improvement of social informatization, the number of broadband users continues to increase, which promotes the continuous development of optical fiber access networks. PON (Passive Optical Network, passive optical network) is the mainstream technology in the optical fiber access network in recent years. The PON system consists of OLT (Optical Line Terminal, optical line terminal), ODN (Optical Distribution Network Unit, optical fiber distribution network) and ONU (Optical Network Unit, optical network unit) composition. Among them, the OLT is the core component of the entire PON system. It provides a high-speed interface between the access network and the core ne...

Problems solved by technology

[0004] Since the telecom service operator and the housing builder are responsible for their own construction, when the user activates the service, it is necessary to perform fiber jumping between the operator and the public distribution box every time. However, the implementation of fiber jumping is complicated and frequently in Fiber jumper at the user access point is prone to jumper connection errors, resulting in information security risks, thereby reducing network reliability
