Method and device for providing AR service in communication system

A user equipment (UE) for an augmented reality (AR) service in a communication system, the UE comprising:

• a transceiver;
• memory configured to store information related to the AR service;
• and
• at least one processor operably coupled to the transceiver and the memory, the at least one processor configured to:
• identify, based on a capability of the UE or an instruction of an application provider in the communication system, whether the UE or an application server generates information on live geometry corresponding to a virtual three-dimension (3D) space in which the UE is positioned,
• generate ambient environment information including at least one piece of information obtained based on an ambient environment of the UE,
• establish a session for receiving an AR service description from the application server,
• receive, from the application server through the transceiver, the AR service description including pipeline information indicating a transmission path related to the AR service and result information for at least one process requested by the UE, and
• transmit, to the application server, the ambient environment information and receive, from the application server, at least one media segment of an AR content based on the ambient environment information,
• wherein the ambient environment information includes the information on the live geometry in case that the UE generate the information on the live geometry, and
• wherein the AR service description includes the information on the live geometry in case that the application server generates the information on the live geometry.

A method performed by an application server for an augmented reality (AR) service in a communication system, the method comprising:

• identifying, based on a capability of a user equipment (UE) or an instruction of an application provider in the communication system, whether the application server or the UE generates information on live geometry corresponding to a virtual three-dimension (3D) space in which the UE is positioned;
• establishing a session with the UE for providing an AR service description;
• transmitting, to the UE, the AR service description including pipeline information indicating a transmission path related to the AR service and result information for at least one process requested by the UE;
• and
• receiving, from the UE, ambient environment information and transmitting, to the UE, at least one media segment of an AR content based on the ambient environment information,
• wherein the ambient environment information includes the information on the live geometry in case that the UE generate the information on the live geometry, and
• wherein the AR service description includes the information on the live geometry in case that the application server generates the information on the live geometry.

An application server for an augmented reality (AR) service in a communication system, the application server comprising:
