First Claim
Patent Images
1. A method for a multicast coordination entity (MCE) to determine a radio bearer in a mobile IPTV system for transmitting same contents to a plurality of terminals, comprising:
- receiving identifiers of contents selected by the terminals and radio channel information from the terminals; and
determining the radio bearer by considering at least one of a share of a usage anticipation subcarrier for each identifier of the contents, a share of the subcarrier influenced by a neighboring cell, and a number of terminals desiring the contents.

Abstract
In a mobile IPTV system, a multicast coordination entity (MCE) acquires information for radio resource allocation for satisfying all terminals through a counting procedure, and determines a radio bearer by considering a share of usage anticipation subcarrier for respective identifiers of contents. A scheduling subject is variable by a characteristic of the determined radio bearer.

10. A method for a multicast coordination entity (MCE) to determine a radio bearer in a mobile IPTV system for transmitting the same contents to a plurality of terminals, comprising:
-
receiving identifiers of contents selected by the terminals from the terminals; finding a share of usage anticipation subcarriers for respective identifiers of the contents; determining it to be a point-to-point radio bearer when the share of the usage anticipation subcarrier is less than a reference value; and determining it to be a point-to-multipoint radio bearer when the share of the usage anticipation subcarrier is greater than the reference value, wherein the reference value is determined by a usage share of the current subcarrier and a share of the subcarrier influenced by a neighboring cells, and the share of the usage anticipation subcarrier is determined by a number of subcarriers occupied by the contents and a number of terminals having selected the contents. - View Dependent Claims (11, 12, 13, 14)

15. A method for a multicast coordination entity (MCE) to determine a radio bearer in a mobile IPTV system for transmitting same contents to a plurality of terminals, comprising:
-
receiving identifiers of contents selected by the terminals from the terminals; calculating a number of terminals for respective identifiers of the contents; and determining a radio bearer by considering at least one of a share of usage anticipation subcarriers of the contents, a share of the subcarrier influenced by a neighboring cell, and a number of terminal desiring the contents starting from an identifier of contents with a lesser number of terminals. - View Dependent Claims (16, 17, 18)
