DATA TRANSMISSION METHOD USING THE NUMBER OF STATIONS JOINED MULTICAST SERVICE, BASE STATION AND TERMINAL DEVICE THEREFOR, AND WIRELESS COMMUNICATION SYSTEM HAVING THE SAME
First Claim
1. A wireless communication system for use in a network where a multicast service is provided to at least one or more terminals in contention-based channel access mode, the system comprising:
- a terminal; and
a wireless communication base station for use in a network where a multicast service is received from a network entity and is provided to at least one or more terminals in contention-based channel access mode of a wireless communication, the base station comprising;
a storage unit for storing terminal information including the number of terminals which have joined the multicast service; and
a priority determining unit for setting a user priority of a data frame to be transmitted using the terminal information.

Abstract
The present invention relates to a wireless communication data transmission method considering the number of terminals requesting services. The present invention provides a wireless communication base station for use in a network where a multicast service is received from a network entity and is provided to at least one or more terminals in contention-based channel access mode of a wireless communication. The base station comprises a storage unit for storing terminal information including the number of terminals which have joined the multicast service, and a priority determining unit for setting a user priority of a data frame to be transmitted using the terminal information. According to the present invention, a priority of data to be transmitted is determined in consideration of the number of serviced terminals, and thus, the data can be reasonably transmitted.

25. A data transmission method for use in a network where a multicast service is received from a network entity and is provided to at least one or more terminals in contention-based channel access mode of a wireless communication, the method comprising the steps of:
-
(a) determining, by a priority determining unit provided to a base station, a user priority of a data frame to be transmitted; (b) examining terminal information of a terminal, which desires to receive the data frame, from a storage unit for storing terminal information of terminals which have joined the multicast service; (c) adjusting the user priority using the terminal information; and (d) determining an AC of the data frame based on the adjusted user priority. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32)

38. A data transmission method for use in a network where a multicast service is received from a network entity and is provided to at least one or more terminals in contention-based channel access mode of a wireless communication, the method comprising the steps of:
-
examining terminal information of a terminal, which desires to receive a data frame to be transmitted, from a storage unit for storing terminal information of terminals which have joined the multicast service; determining, by a priority determining unit provided to a base station, a user priority of the data frame to be transmitted using the terminal information; and determining an AC of the data frame based on the user priority. - View Dependent Claims (39, 40, 41)

42. A data transmission method for use in a network where a multicast service is received from a network entity and is provided to at least one or more terminals in contention-based channel access mode of a wireless communication, the method comprising the steps of:
-
determining, by a priority determining unit provided to a base station, a user priority of a data frame to be transmitted; determining an AC of the data frame based on the user priority; examining terminal information of a terminal, which desires to receive the data frame, from a storage unit for storing terminal information of terminals that have joined the multicast service, if a collision occurs between ACs when the data frame is transmitted; adjusting the user priority using the terminal information; and selecting and transmitting, by a virtual collision handler, a data frame with a highest adjusted user priority. - View Dependent Claims (43)
