A method for supporting periodic and triggered location of a user equipment, UE, in a wireless network performed by the UE, the method comprising: receiving a request for a periodic or triggered location from a location server in the wireless network; sending a response to the location server, the response confirming the periodic or triggered location; detecting a periodic or triggering event; determining whether to report the periodic or triggering event using Control Plane, CP, Optimization and, in response to determining to report the periodic or triggering event using CP Optimization: obtaining event information, the event information comprising at least one of location measurements, a location estimate, a type of detected triggering event, or a combination thereof; obtaining a signaling association with a Radio Access Network, RAN, node in the wireless network, wherein the signaling association does not include a signaling connection to a core network, CN, node; transmitting a first message to the RAN node (110, 114), wherein the first message is a Radio Resource Control, RRC, message and includes an initial Non-Access Stratum, NAS, message, wherein the initial NAS message contains a routing identifier identifying the location server and an event report message containing the event information, wherein the RAN node forwards the initial NAS message to the CN node, wherein the CN node forwards the event report message to the location server; and receiving a second message from the RAN node, wherein the second message includes a NAS response message, wherein the NAS response message contains an event report acknowledgment message. receiving a request for a periodic or triggered location from a location server in the wireless network; sending a response to the location server, the response confirming the periodic or triggered location; detecting a periodic or triggering event; determining whether to report the periodic or triggering event using Control Plane, CP, Optimization and, in response to determining to report the periodic or triggering event using CP Optimization: obtaining event information, the event information comprising at least one of location measurements, a location estimate, a type of detected triggering event, or a combination thereof; obtaining a signaling association with a Radio Access Network, RAN, node in the wireless network, wherein the signaling association does not include a signaling connection to a core network, CN, node; transmitting a first message to the RAN node (110, 114), wherein the first message is a Radio Resource Control, RRC, message and includes an initial Non-Access Stratum, NAS, message, wherein the initial NAS message contains a routing identifier identifying the location server and an event report message containing the event information, wherein the RAN node forwards the initial NAS message to the CN node, wherein the CN node forwards the event report message to the location server; and receiving a second message from the RAN node, wherein the second message includes a NAS response message, wherein the NAS response message contains an event report acknowledgment message. obtaining event information, the event information comprising at least one of location measurements, a location estimate, a type of detected triggering event, or a combination thereof; obtaining a signaling association with a Radio Access Network, RAN, node in the wireless network, wherein the signaling association does not include a signaling connection to a core network, CN, node; transmitting a first message to the RAN node (110, 114), wherein the first message is a Radio Resource Control, RRC, message and includes an initial Non-Access Stratum, NAS, message, wherein the initial NAS message contains a routing identifier identifying the location server and an event report message containing the event information, wherein the RAN node forwards the initial NAS message to the CN node, wherein the CN node forwards the event report message to the location server; and receiving a second message from the RAN node, wherein the second message includes a NAS response message, wherein the NAS response message contains an event report acknowledgment message.
