Abstract
A method and apparatus for transmitting Multimedia Broadcast Multicast Service (MBMS) data for use in a Long Term Evolution (LTE) system is provided. The method includes generating information for use in determining whether a broadcast area changes on inter-cell movement of a terminal, generating a system information block (SIB) including the generated information, and broadcasting the SIM.
Claims22
An information transmission method of a base station in a wireless communication system, the information transmission method comprising:
- generating information for use in determining whether a broadcast area changes due to inter-cell movement of a terminal;
- generating a system information block (SIB) including the generated information;
- and
- broadcasting the SIB,
- wherein the information comprises multimedia broadcast multicast service single frequency network (MBSFN) area information and a MBSFN area change indication flag included in a list of neighbor cells indicating whether a MBSFN is changed per neighbor cell of the base station.
A broadcast information reception method of a terminal in a wireless communication system, the broadcast information reception method comprising:
- receiving a system information block (SIB) from a new cell to which the terminal moves from an old cell;
- determining whether a broadcast area changes based on the SIB;
- and
- determining whether to decode the broadcast data based on a result of the determination,
- wherein the SIB comprises information including multimedia broadcast multicast service single frequency network (MBSFN) area information and a MBSFN area change indication flag included in a list of neighbor cells of the new cell indicating whether a MBSFN is changed in the new cell.
A base station for transmitting information in a wireless communication system, the base station comprising:
- a transceiver configured to transmit and receive signals;
- and
- at least one processor configured to:
- generate information for use in determining whether a broadcast area changes due to inter-cell movement of a terminal,
- generate a system information block (SIB) including the generated information, and
- control the transceiver to broadcast the SIB,
- wherein the information comprises multimedia broadcast multicast service single frequency network (MBSFN) area information and a MBSFN area change indication flag included in a list of neighbor cells indicating whether a MBSFN is changed per neighbor cell of the base station.
A terminal for receiving broadcast information in a wireless communication system, the terminal comprising:
- a transceiver configured to transmit and receive signals to and from a base station;
- and
- at least one processor configured to:
- control the transceiver to receive a system information block (SIB) from a new cell to which the terminal moves from an old cell,
- determine whether a broadcast area changes based on the SIB, and
- determine whether to decode broadcast data based on a result of the determination,
- wherein the SIB comprises information including multimedia broadcast multicast service single frequency network (MBSFN) area information and a MBSFN area change indication flag included in a list of neighbor cells of the new cell indicating whether a MBSFN is changed in the new cell.
