Abstract
A packet communication method of the present invention includes establishing a radio layer 2 connection based on a radio layer 2 protocol between a mobile station and a controller device, determining a transmission timing of a received data packet based on a quality of service set in the data packet, and multiplexing, at the determined transmission timing, the data packet into a radio layer 2 protocol data unit of a fixed length which is transmitted and received on the radio layer 2 connection.
Claims8
A packet communication method comprising the steps of:
- establishing a radio layer 2 connection based on a radio layer 2 protocol, between a mobile station and a controller device;
- determining a transmission timing of a received data packet, based on a quality of service set in the data packet;
- and
- multiplexing, at the determined transmission timing, the data packet into a radio layer 2 protocol data unit of a fixed length which is transmitted and received on the radio layer 2 connection.
A controller device comprising:
- a radio layer 2 connection establishing unit configured to establish, with a mobile station, a radio layer 2 connection based on a radio layer 2 protocol;
- a transmission timing determining unit configured to determine a transmission timing of a received data packet, based on a quality of service set in the data packet;
- and
- a multiplexing unit configured to multiplex, at the determined transmission timing, the data packet into a radio layer 2 protocol data unit of a fixed length which is transmitted and received on the radio layer 2 connection.
A mobile station comprising:
- a radio layer 2 connection establishing unit configured to establish, with a controller device, a radio layer 2 connection based on a radio layer 2 protocol;
- a transmission timing determining unit configured to determine a transmission timing of a received data packet, based on a quality of service set in the data packet;
- and
- a multiplexing unit configured to multiplex, at the determined transmission timing, the data packet into a radio layer 2 protocol data unit of a fixed length which is transmitted and received on the radio layer 2 connection.
A packet communication method comprising the steps of:
- at a mobile station, establishing a radio layer 2 connection based on a radio layer 2 protocol;
- establishing a plurality of tunneling connections between two or more controller devices;
- and
- at a first controller device, referring to a terminal address included in a data packet which is multiplexed on the radio layer 2 connection and transmitted from the mobile station, and relaying the data packet through a tunneling connection associated with the terminal address.
A controller device comprising:
- a tunneling connection establishing unit configured to establish a plurality of tunneling connections with a certain controller device;
- an associating unit configured to associate a terminal address included in a data packet with a tunneling connection;
- a data packet receiving unit configured to receive a data packet which is multiplexed on a radio layer 2 connection and transmitted from a mobile station;
- and
- a relay unit configured to refer to a terminal address included in the received data packet and relay the data packet through a tunneling connection associated with the terminal address.
