US 12,710,548 B2 · Enhanced messaging to handle SPS spoofing

Abstract

Techniques are discussed herein for transmission of location information by a user equipment (UE) to other UEs. A UE receives Satellite Positioning System (SPS) signals and determines whether the SPS signals are reliable. The UE determines a location estimate to be transmitted to other UEs using the SPS signals if the SPS signals are determined to be reliable and using non-SPS information if the SPS signals are determined to be not reliable. The location information is transmitted to other UEs in a message that includes an indication of the source of information used to generate the location estimate. A UE that receives the message may determine its location estimate based, at least in part, on the indication of the source of information, e.g., by determining whether SPS signals are reliable based, at least in part, on the indication of the source of information received in the message.

Claims27

Dependent claims

A method performed by a first user equipment (UE) for transmission of location information, the method comprising:

receiving from a second UE a wireless message that includes a location estimate for the second UE and an indication of a source of information used to generate the location estimate, wherein the source of information comprises SPS (Satellite Positioning System) signals or non-SPS information;
and
determining a location estimate for the first UE based, at least in part, on the indication of the source of information used to generate the location estimate received from the second UE.

A first user equipment (UE) configured for transmitting location information, the first UE comprising:

at least one wireless transceiver configured to wirelessly communicate with entities in a wireless network;
an SPS (Satellite Positioning System) receiver configured to receive SPS signals;
at least one memory;
and
at least one processor coupled to the at least one wireless transceiver, the SPS receiver, and the at least one memory, wherein the at least one processor is configured to:
receive, via the at least one wireless transceiver, from a second UE a wireless message that includes a location estimate for the second UE and an indication of a source of information used to generate the location estimate, wherein the source of information comprises SPS signals or non-SPS information;
and
determine a location estimate for the first UE at least partially based on the indication of the source of information used to generate the location estimate received from the second UE.
