Problems solved by technology

[0007] The present invention aims to provide a kind of ONU authentication method for PON system, to solve the problem in the prior art that maintains the authentication database workload of OLT
[0009] The ONU authentication method of the above embodiment replaces the ONU authentication and authorization of the prior art by adopting user authentication and authorization, so it overcomes the problem of a large workload of maintaining the authentication database of the OLT in the prior art, and then achieves the goal of simplifying ONU authentication.

Embodiment Construction

[0014] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0015] figure 1 Show the flowchart of the ONU authentication method according to the embodiment of the present invention, comprise the following steps:

[0016] Step S10, the ONU accesses the OLT for the first time, and sends the identification information of the ONU to the OLT;

[0017] Step S20, providing authentication information about the user to the OLT to obtain authorization;

[0018] Step S30, after the authorization is passed, the identification information is added to the authentication database to allow the access of the ONU.

[0019] The difference between the above method and the prior art is that: in the prior art, the authentication and authorization of the authentication database is performed for the ONU, whereas here the authentication and authorization is performed for the user. Therefore, as long as the user ob...

Abstract

The invention provides an ONU certificate method for a PON system, which comprises the following steps: ONU is first accessed to OLT and transmits local identification information to OLT; the certification information of a user is provided for the OLT, and authorization is obtained; and the identification information is added to a certification database to permit the accession of the ONU after the authorization is adopted. The invention simplifies the ONU certification of the OLT in the PON system.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an ONU (Optical Network Unit, Optical Network Unit) authentication method used in a PON (Passive Optical Network, Passive Optical Network) system. Background technique [0002] The PON system consists of OLT (Optical Line Terminal, Optical Line Terminal), ONU and ODN (Optical Distribution Network, Optical Distribution Network), where the ONU used for FTTH (Fiber To The Home, Fiber To The Home) is ONT (Optical Network Terminal, optical network terminal). ODN is a point-to-multipoint structure, and one OLT is connected to multiple ONUs through ODN. [0003] In order to prevent illegal ONUs from accessing the OLT, the OLT generally needs to authenticate the ONU. Currently, the authentication of the ONU is generally based on the fixed identification information related to the ONU, such as the serial number of the GPON (Gigabit-capable PON, gigabit passive optical network) ONU. , ...
