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

Abstract

Techniques are discussed herein for supporting periodic or triggered location of a user equipment (UE) using Early Data Transmission (EDT). A location server (LS), such as a 5G LMF, sends a request to a UE for periodic or triggered location and includes a request and / or criteria for using EDT. After confirming the request, the UE monitors for periodic or triggering events and, for each detected event, sends an event report to the LS which may include location information. In embodiments, the UE establishes a signaling connection with a RAN node but not with a core network to send the event report using EDT. The RAN node may then release the signaling connection, either immediately or after the LS returns a single response to the UE.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application Nos. 62 / 689,820, entitled “LOW POWER PERIODIC AND TRIGGERED LOCATION USING EARLY DATA TRANSMISSION,” filed Jun. 25, 2018, and 62 / 732,558, entitled “LOW POWER PERIODIC AND TRIGGERED LOCATION USING EARLY DATA TRANSMISSION,” filed Sep. 17, 2018, which are assigned to the assignee thereof and which are expressly incorporated herein by reference in their entireties.BACKGROUNDBackground Field[0002]The present disclosure relates generally to communication, and more specifically to techniques for supporting periodic and triggered location services for user equipments (UEs) with low power usage.Relevant Background[0003]The Third Generation Partnership Project (3GPP) has defined location solutions, known as Control Plane (CP) location solutions, for a number of Radio Access Network (RAN) types, including a GSM EDGE RAN (GERAN), a Universal Terrestrial RAN (UTRAN), an Evolved Univer...

AI Technical Summary

Benefits of technology

This approach significantly reduces UE battery consumption and network resource utilization by minimizing the duration and frequency of signaling connections, while maintaining accurate location tracking for IoT devices.

Problems solved by technology

These location solutions are typically resource intensive for both a wireless network and a User Equipment (UE).

For a UE, such as an Internet of Things (IoT) UE, that is regularly tracked, e.g., at five minute or one hour intervals, the above-described process is typically battery intensive.

Moreover, for a network supporting millions (or even billions) of UEs and / or IoT UEs, the above-described process would drain resources from the network.
