Low power periodic and triggered location of a mobile device using early data transmission

A location server for supporting periodic and triggered location of a user equipment (UE) comprising:

• an external interface configured to communicate with a wireless network;
• at least one memory;
• and
• at least one processor coupled to the external interface and the at least one memory and configured to send via the external interface a request for a periodic or triggered location to the UE, the request including an indication that the UE may report detected periodic or triggering events using a request for early connection release, a request for immediate connection release, or both;
• receive via the external interface a response from the UE, the response confirming the periodic or triggered location;
• receive via the external interface from a core network (CN) node an event report message and a Release Assistance Indication (RAI) sent by the UE to the CN node, wherein the RAI comprises a request for immediate connection release or a request for early connection release, wherein the request for early connection release comprises an indication that no response message from the location server is expected by the UE, or an indication that one response message from the location server is expected by the UE, wherein the event report message contains event information obtained by the UE after the UE detected a periodic or triggering event, wherein the event information comprises at least one of location measurements, a location estimate, a type of detected triggering event, or a combination thereof;
• determine location information for the UE based on the event information;
• and transmit via the external interface the location information for the UE to another entity.

A location server for supporting periodic and triggered location of a user equipment (UE) comprising:

• means for sending a request for a periodic or triggered location to the UE, the request including an indication that the UE may report detected periodic or triggering events using a request for early connection release, a request for immediate connection release, or both;
• means for receiving a response from the UE, the response confirming the periodic or triggered location;
• means for receiving from a core network (CN) node an event report message and a Release Assistance Indication (RAI) sent by the UE to the CN node, wherein the RAI comprises a request for immediate connection release or a request for early connection release, wherein the request for early connection release comprises an indication that no response message from the location server is expected by the UE, or an indication that one response message from the location server is expected by the UE, wherein the event report message contains event information obtained by the UE after the UE detected a periodic or triggering event, wherein the event information comprises at least one of location measurements, a location estimate, a type of detected triggering event, or a combination thereof;
• means for determining location information for the UE based on the event information;
• and
• means for transmitting the location information for the UE to another entity.

A non-transitory computer readable medium including program code stored thereon, the program code is operable to configure at least one processor in a location server for supporting periodic and triggered location of a user equipment (UE), comprising:

• program code to send a request for a periodic or triggered location to the UE, the request including an indication that the UE may report detected periodic or triggering events using a request for early connection release, a request for immediate connection release, or both;
• program code to receive a response from the UE, the response confirming the periodic or triggered location;
• program code to receive from a core network (CN) node an event report message and a Release Assistance Indication (RAI) sent by the UE to the CN node, wherein the RAI comprises a request for immediate connection release or a request for early connection release, wherein the request for early connection release comprises an indication that no response message from the location server is expected by the UE, or an indication that one response message from the location server is expected by the UE, wherein the event report message contains event information obtained by the UE after the UE detected a periodic or triggering event, wherein the event information comprises at least one of location measurements, a location estimate, a type of detected triggering event, or a combination thereof;
• program code to determine location information for the UE based on the event information;
• and
• program code to transmit the location information for the UE to another entity.
