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.
Claims18
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.
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.
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.
