1. Apparatus comprising:
- at least one processor; and
at least one memory including computer program code which, when executed by the at least one processor, causes the apparatus;
to detect presence of a portable device in a vicinity of a first vehicle based on an identifier of the portable device which is detected at first user equipment, UE, located at the first vehicle;
to cause transmission, from the first UE to a second UE located at a second vehicle in the vicinity of the first vehicle, of the identifier of the portable device and measurement data relating to the portable device and collected at the first vehicle, the measurement data enabling the location of the portable device relative to the second vehicle to be determined at the second vehicle;
to enable receipt, at the first UE from the second UE, of the identifier of the portable device and measurement data relating to the portable device and collected at the second vehicle; and
to determine, at the first vehicle, the location of the portable device relative to the first vehicle based on the measurement data collected at the first vehicle and the measurement data collected at the second vehicle.

3. Apparatus comprising:
-
at least one processor; and at least one memory including computer program code which, when executed by the at least one processor, causes the apparatus; to detect presence of a portable device in a vicinity of a vehicle based on an identifier of the portable device which is detected at user equipment, UE, located at the vehicle; to cause transmission, from the UE to one or more other UEs each located at a different other vehicle in the vicinity of the vehicle, of the identifier of the portable device and measurement data relating to the portable device and collected at the vehicle, the measurement data enabling the location of the portable device relative to the one or more other vehicles to be determined at the one or more other vehicles; to enable receipt, at the UE located at the vehicle from the one or more other UEs, of the identifier of the portable device detected in a vicinity of each of the one or more other vehicles and measurement data relating to the portable device and collected at the one or more other vehicles; and to determine, at the vehicle, the location of the portable device relative to the vehicle based on the measurement data collected at the vehicle and the measurement data collected at the one or more other vehicles. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A method comprising:
-
detecting presence of a portable device in a vicinity of a first vehicle based on an identifier of the portable device which is detected at first user equipment, UE, located at the first vehicle; causing transmission, from the first UE to a second UE located at a second vehicle in the vicinity of the first vehicle, of the identifier of the portable device and measurement data relating to the portable device and collected at the first vehicle, the measurement data enabling the location of the portable device relative to the second vehicle to be determined at the second vehicle; enabling receipt, at the first UE from the second UE, of the identifier of the portable device and measurement data relating to the portable device and collected at the second vehicle; and determining, at the first vehicle, the location of the portable device relative to the first vehicle based on the measurement data collected at the first vehicle and the measurement data collected at the second vehicle. - View Dependent Claims (16)

17. A method comprising:
-
detecting presence of a portable device in a vicinity of a vehicle based on an identifier of the portable device which is detected at user equipment, UE, located at the vehicle; causing transmission, from the UE to one or more other UEs each located at a different other vehicle in the vicinity of the vehicle, of the identifier of the portable device and measurement data relating to the portable device and collected at the vehicle, the measurement data enabling the location of the portable device relative to the one or more other vehicles to be determined at the one or more vehicles; enabling receipt, at the UE located at the vehicle from the one or more other UEs, of the identifier of the portable device detected in a vicinity of each of the one or more other vehicles and measurement data relating to the portable device and collected at the one or more other vehicles; and determining, at the vehicle, the location of the portable device relative to the vehicle based on the measurement data collecting at the vehicle and the measurement data collected at the one or more other vehicles. - View Dependent Claims (18)

19. Apparatus comprising:
-
at least one processor; and at least one memory including computer program code which, when executed by the at least one processor, causes the apparatus; to enable receipt, at a user equipment, UE, located at a vehicle from one or more other UEs each located at a different other vehicle, of an identifier of a portable device detected in a vicinity of each of the other vehicles and measurement data relating to the portable device and collected at the one or more other vehicles, wherein the measurement data is received along with error data indicative of a degree of error in the measurement data; and to determine, at the vehicle, the location of the portable device relative to the vehicle based on the measurement data collected at the one or more other vehicles and the error data by assigning weights to the measurement data based on the error data, and performing a weighted average of locations indicated by the measurement data. - View Dependent Claims (20)
