Abstract
Disclosed are a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT), which may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure relates to wireless communications technologies, and more particularly, a method and an apparatus for transmitting a vehicle to everything (V2X) message via an enhanced Multimedia Broadcast Multimedia Service (eMBMS) bearer.
Claims10
A method performed by a server, the method comprising:
- receiving, from a terminal, a first vehicle to everything (V2X) message including location information on the terminal;
- determining a first multimedia broadcast multicast service (MBMS) broadcast area for a V2X service based on the location information on the terminal;
- and
- transmitting, to a core network entity, a request message for the V2X service including an MBMS broadcast area parameter associated with the first MBMS broadcast area and a first temporary mobile group identity (TMGI) associated with first MBMS data for the V2X service,
- wherein the MBMS broadcast area parameter associated with the first MBMS broadcast area includes at least one list of MBMS service area identifications (SAIs) mapped to the location information on the terminal,
- wherein the first MBMS data associated with the V2X message is broadcasted within the first MBMS broadcast area, and
- wherein the first TMGI is used for second MBMS data associated with a second V2X message, in case that the first MBMS broadcast area is not overlapped with a second MBMS broadcast area for broadcasting the second MBMS data.
A server, comprising:
- a transceiver;
- and
- at least one processor configured to:
- receive, from a terminal via the transceiver, a first vehicle to everything (V2X) message including location information on the terminal,
- determine a first multimedia broadcast multicast service (MBMS) broadcast area for a V2X service using the location information on the terminal, and
- transmit, to a core network entity, via the transceiver, a request message for the V2X service including an MBMS broadcast area parameter associated with the first MBMS broadcast area and a first temporary mobile group identity (TMGI) associated with first MBMS data for the V2X service,
- wherein the MBMS broadcast area parameter associated with the first MBMS broadcast area includes at least one MBMS service area identification (SAI) mapped to the location information on the terminal,
- wherein the first MBMS data associated with the V2X message is broadcasted within the first MBMS broadcast area, and
- wherein the first TMGI is used for second MBMS data associated with a second V2X message, in case that the first MBMS broadcast area is not overlapped with a second MBMS broadcast area for broadcasting the second MBMS data.
