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 a plurality of optical network units (ONUs) connected the OLT via an optical distribution network (ODN), the method comprising:
- receiving a terminal serial number from an ONU;
transmitting a request for logic registration code if it is determined that the terminal serial number does not match a terminal serial number stored on the OLT;
in response to the request for logic registration code, receiving, at the OLT, a physical layer operation and maintenance (PLOAM) message from the ONU in the PON the PLOAM message including a first field for carrying an ONU identifier (ONU-ID) and a second field for carrying a first logic registration code, wherein the ONU-ID is assigned by the OLT to identify the ONU and wherein the first logic registration code is assigned to a user by an operation management system communicatively connected to the OLT, and is provisioned for the authentication;
judging, at the OLT, whether the first logic registration code received from the ONU matches a second logic registration code provisioned by the operation management system to the OLT;
promoting, at the OLT, the ONU into service if the first logic registration code received from the ONU matches the second logic registration code.

Abstract
A method and apparatus for authentication in a passive optical network are disclosed. In the disclosure, a PLOAM message is sent from an ONU to an OLT, where the PLOAM message includes a first field for carrying an ONU identifier (ONU-ID) and a second field for carrying a first logic registration code, where the ONU-ID is assigned by the OLT to identify the ONU and wherein the first logic registration code is assigned to a user by an operation management system communicatively connected to the OLT and provisioned to the user for authentication. The OLT is configured to judge whether the first logic registration code received from the ONU matches with a second logic registration code provisioned by the operation management system to the OLT and to promote the ONU into service if the first logic registration code matches with the second logic registration code.

16. A method in a passive optical network (PON) comprising an optical line terminal (OLT) and a plurality of optical network units (ONUs) connected to the OLT via an optical distribution network (ODN), the method comprising:
-
transmitting a terminal serial number from an ONU to the OLT; receiving a request for logic registration code from the OLT if the OLT determes that the terminal serial number does not match a terminal serial number stored on the OLT; in response to the request, generating a physical layer operation and maintenance (PLOAM) message from an ONU in the PON to the OLT, the PLOAM message including a first field for carrying an ONU identifier (ONU-ID) and a second field for carrying a logic registration code, wherein the ONU-ID is assigned by the OLT to identify the ONU and wherein the logic registration code is assigned to a user by an operation management system communicatively connected to the OLT, and is provisioned to the OLT for authentication, wherein the logic registration code is different from a terminal serial number of the ONU; transmitting the PLOAM message. - View Dependent Claims (17, 18)
