Abstract

According to certain embodiments, a method by a radio node operating as a location server is provided. The method includes receiving, from a first wireless device, user input identifying a marked location and associating the marked location with a Cellular-Ubiety Identifier (ID). Measurement information is obtained for the first wireless device. The measurement information is stored in a database with the Cellular-Ubiety ID.

First claim

The invention claimed is:

1. A method by a radio node operating as a location server, the method comprising:
receiving, from a first wireless device, user input identifying a marked location;
associating the marked location with a Cellular-Ubiety Identifier (ID);
obtaining measurement information for the first wireless device;
storing, in a database, the measurement information with the Cellular-Ubiety ID;
obtaining current measurement information for a second wireless device;
performing a comparison of the current measurement information for the second wireless device to the measurement information for the first wireless device; and
based on the comparison of the current measurement information for the second wireless device to the measurement information for the first wireless device, determining a location of the second wireless device relative to the marked location associated with the Cellular-Ubiety ID.

2. The method of claim 1 , wherein:
obtaining the measurement information for the first wireless device comprises:
transmitting a request for the measurement information to the first wireless device; and
in response to the request, receiving the measurement information from the first wireless device, and
the measurement information received from the first wireless device comprises at least one of:
one or more cell identifiers detected by the wireless device;
quantized power level information and signal-to-noise measurements for signals received from one or more cells detected by the wireless device;
Reference Signal Receive Power (RSRP) for signals received from the one or more cells detected by the wireless device;
Reference Signal Receive Quality (RSRQ) for signals received from the one or more cells detected by the wireless device; and
Time Difference of Arrival (TDOA) with respect to a plurality of cells as measured by the wireless device.

3. The method of claim 1 , wherein:
obtaining the measurement information for the first wireless device comprises:
transmitting a request for the measurement information to a network node providing communication services to the first wireless device; and
in response to the request, receiving the measurement information from the network node, and
a first portion of the measurement information is measured by the network node, the first portion of the measurement information comprising at least one of:
quantized power level information and signal-to-noise information as measured on each of a plurality of antennas of the network node;
Time Difference of Arrival (TDOA) as measured on each of the plurality of antennas of the network node; and
an Angle of Arrive (AoA) for each of signal received from the first wireless device by the network node.

4. The method of claim 1 , wherein:
obtaining the measurement information for the first wireless device comprises performing, by the radio node, a measurement procedure on at least one signal received from the first wireless device to directly obtain a first portion of the measurement information, and
the first portion of the measurement information comprises at least one of:
quantized power level information and signal-to-noise information as measured on each of a plurality of antennas of the network node;
Time Difference of Arrival (TDOA) as measured on each of the plurality of antennas of the network node; and
an Angle of Arrive (AoA) for each of signal received from the first wireless device by the network node.

5. The method of claim 3 , wherein a second portion of the measurement information is measured by the first wireless device, the second portion of the measurement information comprising at least one of:
one or more cell identifiers detected by the first wireless device;
quantized power level information and signal-to-noise measurements for signals received from one or more cells detected by the first wireless device;
Reference Signal Receive Power (RSRP) for signals received from the one or more cells detected by the first wireless device;
Reference Signal Receive Quality (RSRQ) for signals received from the one or more cells detected by the first wireless device; and
Time Difference of Arrival (TDOA) with respect to a plurality of cells as measured by the first wireless device.

6. The method of claim 1 , further comprising:
receiving information comprising at least one of:
a map of an area associated with the marked location;
an indication of a detection zone;
a marker description associated with the marked location, the marker description comprising at least one of an augmented reality image, an augmented reality video and a text description;
associating the information with the measurement information and the Cellular-Ubiety ID.

7. The method of claim 1 , further comprising:
in response to determining that the location of the second wireless device is within a detection zone of the marked location, transmitting a message comprising at least one of:
an indication of the location of the second wireless device within the detection zone of the marked location;
the Cellular-Ubiety ID;
a distance indication comprising a distance between the second wireless device and the marked location associated with the Cellular-Ubiety ID;
a relative Euclidean distance to the marked location associated with the Cellular-Ubiety ID.

8. The method of claim 1 , wherein the Cellular-Ubiety ID is a universally unique identifier (UUID) comprising at least one of:
a bluetooth device address;
a Bluetooth Public Device Address (BT-PDA);
an iBeacon UUID;
an Android Beacon Identifier;
a MAC address;
a Version 1 UUID that comprises a date-time and a MAC Address;
a Version 2 UUID that comprises a Distributed Computing Environment (DCE) Security version;
a DCE security version UUID;
a Version 3 or Version 5 UUID that comprises a name-based identifier;
a Version 4 UUID that comprises a random identifier;
a uniquely identifiable alphanumeric assignment; and
a random hash value that has a unique identity.

9. The method of claim 1 , wherein the radio node comprises a core network node, an eNodeB, or a gNodeB.

10. A radio node operating as a location server, the radio node comprising:
memory, storing instructions; and
processing circuitry configured to execute the instructions to cause the radio node to:
receive, from a first wireless device, user input identifying a marked location;
associate the marked location with the Cellular-Ubiety Identifier (ID);
obtain measurement information for the first wireless device;
store, in a database, the measurement information with the Cellular-Ubiety ID;
obtaining current measurement information for a second wireless device;
performing a comparison of the current measurement information for the second wireless device to the measurement information for the first wireless device; and
