Abstract
Provided are a method for controlling, by a multi-cell coordination entity (MCE), a session for transmitting a V2X message in a wireless communication system, and an apparatus for supporting the same. The method comprises the steps of: receiving, by the MCE, a cell ID and a multimedia broadcast multicast service (MBMS) service area identity (SAI) from a mobility management entity (MME); determining a multicast broadcast single frequency network (MBSFN) area to which the V2X message is to be transferred on the basis of the cell ID; transmitting a session control message to a base station which belongs to the determined MBSFN area, wherein the cell ID may be an ID of a cell to which the V2X message is transmitted.
Claims13
A method of controlling a session for transmitting a vehicle to everything (V2X) message by a multi-cell coordination entity (MCE) in a wireless communication system, the method comprising:
- receiving a cell identifier (ID) and a multimedia broadcast multicast service (MBMS) service area identity (SAI) from a mobility management entity (MME),
- wherein the cell ID is an ID of a cell in which the V2X message is transmitted, and
- wherein the MBMS SAI is set to zero by a broadcast multicast service center (BM-SC), based on the BM-SC receiving the cell ID;
- based on the cell ID, determining a multicast broadcast single frequency network (MBSFN) area where the V2X message is to be transferred;
- and
- transmitting a session control message to a base station which belongs to the determined MBSFN area.
A method of controlling a session for transmitting a vehicle to everything (V2X) message by a multi-cell coordination entity (MCE) in a wireless communication system, the method comprising:
- receiving a session control message comprising a cell list and a source cell information from a mobility management entity (MME),
- wherein the cell list comprises cells to which the V2X message is to be transmitted, and
- wherein the source cell information represents a cell in which the V2X message is transmitted;
- filtering the distribution of the session control message based on the cell list and the source cell information;
- and
- transmitting the session control message to a base station,
- wherein the base station is to receive the session control message based on the filtering.
A multi-cell coordination entity (MCE) for controlling a session for transmitting a vehicle to everything (V2X) message in a wireless communication system, the MCE comprising:
- a memory;
- a transceiver;
- and a processor for coupling the memory and the transceiver, wherein the processor is configured to:
- control the transceiver to receive a cell identifier (ID) and a multimedia broadcast multicast service (MBMS) service area identity (SAI) from a mobility management entity (MME),
- wherein the cell ID is an ID of a cell in which the V2X message is transmitted, and
- wherein the MBMS SAI is set to zero by a broadcast multicast service center (BM-SC), based on the BM-SC receiving the cell ID;
- based on the cell ID, determine a multicast broadcast single frequency network (MBSFN) area where the V2X message is to be transferred;
- and
- control the transceiver to transmit a session control message to a base station which belongs to the determined MBSFN area.
