at least one memory including computer program code;

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:

measure signal strength of two or more wireless device discovery messages received from a wireless communication device, the wireless discovery messages including a device address of the wireless communication device, wherein the two or more wireless discovery messages are received from the wireless communication device at a first measured periodic interval;

store the device address of the wireless communication device, the first measured periodic interval of the received two or more wireless discovery messages and the measured signal strength of the received two or more wireless discovery messages;

detect two or more other wireless device discovery messages having a different device address, at a second measured periodic interval;

measure received signal strengths of the two or more other wireless device discovery messages; and

if no messages are received including the device address of the wireless communication device, compare the stored signal strength of the two or more wireless discovery messages received from the wireless communication device with the measured signal strength of the received two or more other wireless device discovery messages and compare the stored first measured periodic interval with the second measured periodic interval to determine whether a source of the other wireless device discovery messages is the wireless communication device.

8. The apparatus of claim 7 , further comprising:

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
