Method for dynamically establishing logical link in PON systems and an optical network unit for the method
First Claim
1. In a PON system including an optical line terminal (OLT) at a center station, a plurality of optical network units (ONUs) having at least one network interface for communicating with one or more user units at subscribers'"'"' sites, and an optical transmission line shared by the plurality of ONUs to optically connect between the OLT and the plurality of ONUs, a method for dynamically establishing a logical link comprising:
- detecting a start-up of an application on a user unit connected via a network interface, by an ONU;
requesting the OLT, by the ONU, to assign a new logical link for the application when the start-up of the application is detected; and
assigning the new logical link responsive to the requesting and establishing the new logical link between the OLT and the user unit.

Abstract
The invention is applied to a PON system including an optical line terminal (OLT) at a center station, a plurality of optical network units (ONUs) at subscribers'"'"' sites, and an optical transmission line shared by the plurality ONUs to optically connect between the OLT and the plurality of ONUs. Each of the ONUs requests the OLT to assign a logical link according to start-up of an application.

5. An optical network unit (ONU) disposed at each subscriber'"'"'s site in a PON system comprising:
-
at least one network interface for one or more communication devices; first means to request an OLT in the PON system to assign a logical link in response to a predetermined inquiry message received after the ONU is powered on; a start-up detector to detect a start-up of a communication device connected to the ONU via a network interface; and second means to request the OLT to assign a new logical link for the communication device when the start-up of the communication device is detected. - View Dependent Claims (6, 7, 8)
