Abstract
A Passive Optical Network (PON)-based system and method for providing handover between Optical Network Terminals (ONTs) are provided. The PON-based system may include an Optical Line Terminal (OLT), and an ONT to relay communication between the OLT and a mobile terminal. When the mobile terminal is connected to the ONT, the ONT may transmit a WiFi location update alarm message to the OLT, and the OLT may update a Look-Up Table (LUT) in response to the WiFi location update alarm message.
Claims8
A Passive Optical Network (PON)-based system, comprising:
- an Optical Line Terminal (OLT);
- and
- an Optical Network Terminal (ONT) to relay communication between the OLT and a mobile terminal,
- wherein, when the mobile terminal is connected to the ONT, the ONT transmits a WiFi location update alarm message to the OLT, and
- the OLT updates a Look-Up Table (LUT), in response to the WiFi location update alarm message,
- wherein, when the ONT transmits the WiFi location update alarm message to the OLT, the OLT transmits a WiFi location update Get message to the ONT, to request location update information,
- the ONT generates the location update information, and transmits the generated location update information to the OLT, and
- the OLT updates the LUT using the received location update information.
An operation method of a Passive Optical Network (PON)-based system, the operation method comprising:
- transmitting, by an Optical Network Terminal (ONT), a WiFi location update alarm message to an Optical Line Terminal (OLT), when a mobile terminal is connected to the ONT;
- and
- updating, by the OLT, a Look-Up Table (LUT), in response to the WiFi location update alarm message,
- wherein when the mobile terminal is initially connected to the ONT:
- transmitting, by the ONT, a WiFi location update alarm message to the OLT;
- requesting, by the OLT, the ONT to transmit location update information, in response to the WiFi location update alarm message;
- receiving, by the OLT, at least one of ONT-ID and a source MAC address of the mobile terminal, as the location update information from the ONT;
- and
- updating, by the OLT, the LUT using the received location update information.
