Apparatus supporting an MBMS service
Provided is a method and apparatus that may control a configuration and operation of a network including a base station to support a multicast and broadcast multimedia service in a cellular system and may control an operation of a terminal and the like, and thus, may effectively provide a multimedia service in the cellular system.
1. A method of providing, by a base station, a Multimedia Broadcast Multicast Service (MBMS) to a terminal, the method comprising:
transmitting, to the terminal, location information of radio resource used to transmit an MBMS Control Channel (MCCH), modulation and coding information applied to the MCCH, and change information of the MCCH; and
transmitting the MCCH to the terminal by using the location information and the modulation and coding information,
wherein the MCCH comprises control information associated with MBMS Traffic Channel (MTCH); and
wherein, to identify the MCCH and the MTCH mapped within a same sub-frame, a Media Access Control (MAC) header comprises identification information of the MCCH and/or identification information of the MTCH.
2. The method of claim 1 , wherein the change information of the MCCH comprises at least one of a repetition period of the MCCH, a changing period of the MCCH, and a changing frame offset of the MCCH.
3. The method of claim 1 , further comprising:
transmitting, to the terminal, an MCCH change notification notifying that a change of the MCCH.
4. The method of claim 1 , further comprising:
transmitting, to the terminal, an area identifier of an adjacent MBMS Single Frequency Network (MBSFN) adjacent to an MBSFN to which the base station belongs.
5. The method of claim 1 , wherein the MCCH and the MTCH are mapped within the same sub-frame and thereby are transmitted to the terminal.
6. A method of receiving, by a terminal, a Multimedia Broadcast Multicast Service (MBMS), the method comprising:
monitoring an MBMS Control Channel (MCCH) change notification notifying a change of the MCCH;
receiving, from a base station, location information of radio resource used to transmit the MCCH, modulation and coding information applied to the MCCH, and change information of the MCCH; and
receiving the MCCH, from the base station, based on the location information and the modulation and coding information,
wherein the MCCH comprises control information associated with MBMS Traffic Channel (MTCH), and
wherein, to identify the MCCH and the MTCH mapped within a same sub-frame, a Media Access Control (MAC) header comprises identification information of the MCCH and/or identification information of the MTCH.
7. The method of claim 6 , wherein the change information of the MCCH comprises at least one of a repetition period of the MCCH, a changing period of the MCCH, and a changing frame offset of the MCCH.
8. The method of claim 6 , further comprising:
receiving an area identifier of an adjacent MBMS Single Frequency Network (MBSFN) adjacent to an MBSFN to which the base station belongs.
9. The method of claim 6 , wherein the MCCH and the MTCH are mapped within the same sub-frame and thereby are transmitted to the terminal.
