Method and apparatus for authentication in passive optical network
First Claim
1. A method for authentication in a passive optical network (PON) comprising an optical line terminal (OLT) and an optical network unit (ONU), the method comprising:
- receiving, by the OLT, a first terminal serial number and a logic registration code of the ONU;
determining, by the OLT, whether the first terminal serial number matches with a second terminal serial number stored on the OLT;
determining, by the OLT, when the first terminal serial number does not match the second terminal serial number, whether the first logic registration code received from the ONU matches a second logic registration code stored on the OLT; and
determining, by the OLT, that the ONU is a valid ONU and assign a formal ONU identifier (ONU-ID) to the ONU, if the first logic registration code matches the second logic registration code.

Abstract
A method and apparatus for authentication in a passive optical network are disclosed. In the disclosure, a first terminal serial number of an ONU and a first logic registration code are transmitted from the ONU to an OLT; if the OLT determines that the first terminal serial number does not match a second terminal serial number stored on the OLT, the OLT judges whether the first logic registration code received from the ONU matches a second logic registration code stored on the OLT; the OLT stores the first terminal serial number received from the ONU on the OLT if the first logic registration code matches the second logic registration code.

5. An apparatus comprising an optical line terminal (OLT) coupled to an optical network unit (ONU), wherein the OLT is configured for:
-
receiving, by the OLT, a first terminal serial number and a logic registration code of the ONU; determining, by the OLT, whether the first terminal serial number matches with a second terminal serial number stored on the OLT; determining, by the OLT, when the first terminal serial number does not match the second terminal serial number, whether the first logic registration code received from the ONU matches a second logic registration code stored on the OLT; and determining, by the OLT, that the ONU is a valid ONU and assign a formal ONU identifier (ONU-ID) to the ONU, if the first logic registration code matches the second logic registration code. - View Dependent Claims (6, 7, 8)

9. A method performed on an optical network unit (ONU), comprising:
-
transmitting, by the ONU, a first terminal serial number and a logic registration code of the ONU to a central office comprising an optical line terminal (OLT) when the ONU logs on at a first time; receiving, by the ONU, a request for a logic registration code from the central office, if the central office determines that the first terminal serial number does not match a second terminal serial number; in response to the request, transmitting, by the ONU, a logic registration code to the central office for authentication; receiving, by the ONU, a formal ONU identifier (ONU-ID), when the first logic registration code matches the second logic registration code after the first terminal serial number does not match the second terminal serial number stored on the OLT. - View Dependent Claims (10, 11)

12. An optical network unit (ONU) comprising:
-
a storing module, configured to store a terminal serial number and a logic registration code; a transmitting module, configured to transmit a first terminal serial number to a central office comprising an optical line terminal (OLT) when the ONU logs on at a first time, and a receiving module, configured to receive a request for a logic registration code from the central office, if the central office determines that the first terminal serial number does not match a second terminal serial number stored thereon; wherein the transmitting module, further configured to transmit a logic registration code to the central office in response to the request for logical registration code; wherein the receiving module, further configured to receive a formal ONU identifier (ONU-ID), when the first logic registration code matches the second logic registration code stored on the OLT. - View Dependent Claims (13, 14)
