Apparatus and method for providing low-latency location information service in wireless communication system

An apparatus of an access and mobility function (AMF) in a wireless communication system, the apparatus comprising:

• a transceiver;
• and
• at least one processor,
• wherein the at least one processor is configured to:
• receive, from a user equipment (UE), a UE-originated location information request message including first location quality of service (QoS) information,
• receive, from a gateway mobile location center (GMLC) or a network exposure function (NEF), a UE-terminated location information request message including second location QoS information,
• determine updating of a UE configuration based on the first location QoS information and the second location QoS information,
• transmit, to the UE, a UE configuration update command message, and
• transmit, to a base station related to the UE, a radio access network (RAN) update message in response to reception of a UE configuration update complete message.

A method performed by a user equipment (UE) in a wireless communication system, the method comprising:

• transmitting, to an access and mobility function (AMF), a UE-originated location information request message including first location quality of service (QoS) information;
• receiving, from the AMF, a UE configuration update command message;
• and
• transmitting, to the AMF, a UE configuration update complete message,
• wherein the UE configuration update command message is determined based on the first location QoS information and a second QoS information, and
• wherein the second QoS information is included in a UE-terminated location information request message transmitted from a gateway mobile location center (GMLC) or a network exposure function (NEF).
