Abstract
A method for managing a multicast and broadcast service in a base station according to an embodiment of the present invention includes: transmitting a multicast and broadcast service control channel to a terminal; transmitting an indicator channel for indicating a change of the multicast and broadcast service control channel by using a unicast control channel when the multicast and broadcast service control channel is changed, to the terminal; and transmitting the changed multicast and broadcast service control channel to the terminal.
Claims14
A method for managing a multicast and broadcast service in a base station, comprising:
- transmitting a multicast and broadcast service control channel to a terminal;
- transmitting an indicator channel for indicating a change of the multicast and broadcast service control channel by using a unicast control channel when the multicast and broadcast service control channel is changed, to the terminal, wherein the unicast control channel includes an identifier to indicate a change in size of the multicast and broadcast service control channel;
- and
- transmitting the changed multicast and broadcast service control channel to the terminal,
- wherein the base station counts a number of terminals in a connected state that respond to an inquiry of intention to receive the multicast and broadcast service,
- wherein when the counted number is larger than a predetermined reference, the base station provides the multicast and broadcast service to the terminals, and when the counted number is equal to or less than the predetermined reference, the base station transmits the indicator channel to a terminal in an idle state and counts a number of terminals in the idle state that respond to the inquiry.
A method for managing a multicast and broadcast service in a base station, comprising:
- transmitting an indicator channel for inquiring of an intention to receive the multicast and broadcast service to a terminal;
- receiving a response to an inquiry of intention to receive the service from the terminal:
- and
- transmitting the multicast and broadcast service control channel to the responding terminal,
- wherein the base station counts a number of terminals in a connected state that respond to the inquiry,
- wherein when the counted number is larger than a predetermined reference, the base station provides the multicast and broadcast service to the terminals, and when the counted number is equal to or less than the predetermined reference, the base station transmits the indicator channel to terminals in an idle state and counts a number of terminals in the idle state that respond to the inquiry,
- wherein the indicator channel comprises a unicast control channel that includes an identifier to indicate a change in size of the multicast and broadcast service control channel.
A device for managing a multicast and broadcast service, comprising:
- a service control channel transmitter that transmits a multicast and broadcast service control channel to a terminal;
- and
- an indicator channel transmitter that transmits a first indicator channel for indicating a change of the multicast and broadcast service control channel by using a unicast control channel when the multicast and broadcast service control channel is changed, wherein the unicast control channel includes an identifier to indicate a change in size of the multicast and broadcast service control channel,
- wherein the base station counts a number of terminals in a connected state that respond to an inquiry of intention to receive the service,
- wherein when the counted number is larger than a predetermined reference, the base station provides the multicast and broadcast service to the terminals, and when the counted number is equal to or less than the predetermined reference, the base station transmits the indicator channel to terminals in an idle state and counts a number of terminals in the idle state that respond to the inquiry.
