Claim 12:
13. A mobile phone fitted with a mobile phone case comprising an electronic device comprising a radio communication module and a secure element including a processor and a memory, the secure element being connected to the radio communication module and the processor being configured to:
obtain, from the radio communication module, a first beacon message received by the radio communication module from a beacon device at a first time point,
determine in real-time a first distance between the electronic device and the beacon device at the first time point,
obtain, from the radio communication module, a second beacon message received by the radio communication module from the beacon device at a second time point, wherein the first time point and the second time point are different time points,
determine in real-time a second distance between the electronic device and the beacon device at the second time point,
determine whether the first distance and the second distance are below a proximity threshold for the beacon device with respect to the electronic device, and
upon determining that the first distance and the second distance are below the proximity threshold, store a beacon identifier of the beacon device in the memory of the secure element,
read, from the first beacon message or the second beacon message, a beacon status indicator indicating at least one of: a beacon device status or a beacon user status indicative of a status of a user associated with the beacon device,
filter a particular beacon message, from the read first beacon message or the second beacon message, using a filter parameter and at least one of: the beacon status indicator or a beacon signal strength, wherein the filter parameter is a dynamically set filter parameter adapted according to a set of filter rules stored in the memory, the filter rules defining at least locations or times during which the filter parameters are adapted,
determine in real-time filtered current location information using transmission properties of the particular beacon message, and
store filtered current location information in the memory of the secure element.
