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 of the ONU;
receiving, by the OLT, 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, whether the first logic registration code received from the ONU matches a second logic registration code stored on the OLT if the first terminal serial number does not match the second terminal serial number; 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.

-
receiving, by the OLT, a first terminal serial number of the ONU; receiving, by the OLT, 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, whether the first logic registration code received from the ONU matches a second logic registration code stored on the OLT if the first terminal serial number does not match the second terminal serial number; 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 (2, 3, 4)

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)
