Embodiment Construction

[0024] Obtaining the location of a mobile device that is accessing a wireless network can be useful for many applications including, for example, emergency calling, personal navigation, asset tracking, locating friends or family members, and the like. However, the location of a mobile device typically requires the mobile device and / or the network to use resources for things such as transmitting uplink (UL) signals or downlink (DL) signals that can be measured by another device, conveying to the mobile device that can be used for Obtaining measurement results and / or assisting data to determine a position and to perform processing and communication purposes, among other things. Resource usage, especially when multiple mobile devices need to be located over a certain period of time (for example, hundreds, thousands, or millions of mobile devices that may need to be located hourly or daily over a large wireless network) Yes, the resource usage on the network side may increase sign...

Abstract

Techniques described herein are directed to increasing a quantity of location-related information broadcast by wireless nodes. In one embodiment, a user equipment (UE) sends a request to a wireless node for broadcast of an increased quantity of location-related information for a wireless access type and the wireless node broadcasts the increased quantity of location-related information using the wireless access type. The wireless node may transfer the request to other wireless nodes which may similarly broadcast the increased quantity of location-related information using the wireless access type. The UE may receive the increased quantity of location-related information using the wireless access type and may then obtain location information such as a location estimate for the UE. In some embodiments, the increased quantity of location-related information may comprise a positioning reference signal or location assistance data.

Background technique [0001] Obtaining the location of a mobile device that is accessing a wireless network can be useful for many applications including, for example, emergency calling, personal navigation, asset tracking, locating friends or family members, and the like. However, locating a mobile device typically requires the mobile device and / or the network to use resources for things such as transmitting uplink signals or downlink signals that can be measured by another device, conveying information that can be used by the mobile device to obtain measurements, and / or or assistance data for determining positioning and for purposes such as processing and communication. Resource usage, especially when multiple mobile devices need to be located over a certain period of time (for example, hundreds, thousands, or millions of mobile devices that may need to be located hourly or daily over a large wireless network) Yes, the resource usage on the network side may increase signific...
