Abstract

A technique for identifying at least one mobile terminal travelling in a vehicle is disclosed, wherein the vehicle comprises a connected device. In a method aspect, the method comprises initializing a list of identifiers, IDs, of at least one candidate mobile terminal currently travelling in the vehicle, obtaining a current first position of the connected device and a current second position of the at least one candidate mobile terminal, comparing the current first position and the current second position so as to determine whether the current first and second positions match, and iteratively refining the list of IDs depending on the match of the current first and second positions by repeating the steps of obtaining and comparing until a predetermined condition is met.

25. A method for identifying at least one mobile terminal travelling in a vehicle comprising a connected device, the method comprising:

initializing a list of identifiers (IDs) of at least one candidate mobile terminal currently travelling in the vehicle;

obtaining a current first position of the connected device and a current second position of the at least one candidate mobile terminal;

comparing the current first position and the current second position so as to determine whether the current first and second positions match; and

iteratively refining the list of IDs depending on the match of the current first and second positions by repeating the obtaining and comparing until a predetermined condition is met, wherein;

the predetermined condition to be met is a predetermined number of iterations during which the list remains unchanged; and

the iteratively refining the list of IDs comprises removing an ID from the list of candidate mobile terminals if the current first position of the connected device and the second position of the at least one candidate mobile terminal do not match.

26. The method of claim 25, wherein the connected device is or comprises a Subscriber Identity Module (SIM) card installed in the vehicle.

27. The method of claim 26, wherein the SIM card is attached to at least one of the following items installed in the vehicle:

an emergency call device;

a diagnostics device;

a car theft protection device;

a Wi-Fi hotspot;

a navigation device;

an entertainment system;

a mobile telephone; and

/or

a mobile terminal connected to the central computer of the vehicle.

28. The method of claim 25, wherein the IDs are constituted by or derived from International Mobile Subscriber Identities.

29. The method of claim 25, further comprising, prior to the initializing, pre-populating the list of IDs with IDs of regular travelers related to the connected device.

30. The method of claim 29, wherein the pre-populating is performed by registering subscribers at a core network node.

31. The method of claim 29, wherein the pre-populating is performed by obtaining IDs of all mobile terminals in a cell on which the connected device currently camps on.

32. The method of claim 31, wherein the IDs of the mobile terminals are obtained from one or more of:

a Mobility Management Entity (MME) providing a list of mobile terminals in a connected state for a given base station;

the mobile terminals or the MME configured to perform cell reporting during handover;

the mobile terminals in the connected state providing at least one of signal strength information and their respective distance from a base station;

an Internet Protocol Multimedia Subsystem providing network-provided location information; and

another core network node.

33. The method of claim 29, wherein the pre-populating is performed based on at least one of:

information from previously created lists of IDs of the at least one candidate mobile terminal;

previous call logs from a charging system;

information on family and friends from a Customer Relationship Management system; and

historical information based on one of terminal location and movement statistics.

34. The method of claim 25, further comprising, prior to the initializing, triggering commencement of the initializing by a start event of the vehicle.

35. The method of claim 34, wherein the triggering is performed by at least one of:

the connected device;

a core network node; and

a user.

36. The method of claim 35, wherein, if the triggering is performed by the connected device, the connected device performs the triggering based on at least one of:

an event signaling the start of the vehicle;

a movement of the vehicle; and

an event signaling a special condition detected by the connected device.

37. The method of claim 36, wherein:

the event signaling the start of the vehicle is one of start and ignition of the vehicle; and

/or

the special condition is a safety-critical condition of the vehicle.

38. The method of claim 35, wherein, if the triggering is performed by the core network node, the core network node performs the triggering based on booting or activating the connected device while an event signaling the start or movement of the vehicle is received.

39. The method of claim 35, wherein, if the triggering is performed by the user or a core network node, a Passenger Identification Service (PIS) node may perform, based on the triggering, one of booting and activating the connected device while an event signaling the start or movement of the vehicle is received.

40. The method of claim 35, wherein, if the triggering is performed by the user, the user performs the triggering based on informing the network concerning an imminent intention to travel with or drive the vehicle.

41. The method of claim 25, wherein the comparing and iteratively refining are further based on at least one of:

a cell ID of the connected device;

a signal strength indicator of an associated base station related to the cell ID of the connected device;

a timing advance parameter of the associated base station related to the cell ID of the connected device;

Global Positioning System coordinates of the base station and the connected device; and

Media Access Control addresses visible to a local Wi-Fi hotspot.

42. The method of claim 25, wherein the removing is further based on at least one of:

a distance from the connected device to the associated base station matches, within a tolerance, a distance from the at least one candidate mobile terminal to the associated base station;

signal strength variations of the connected device and the at least one candidate mobile terminal both exhibit a similar pattern and match with an expected pattern on the site of the vehicle; and

the MAC address of the candidate mobile terminal having a Wi-Fi status ON is visible in an access point of the connected device.

43. A non-transitory computer readable recording medium storing a computer program product for identifying at least one mobile terminal travelling in a vehicle comprising a connected device, the computer program product comprising software instructions which, when run on processing circuitry of a computing device, causes the computing device to:

initialize a list of identifiers (IDs) of at least one candidate mobile terminal currently travelling in the vehicle;

obtain a current first position of the connected device and a current second position of the at least one candidate mobile terminal;

compare the current first position and the current second position so as to determine whether the current first and second positions match; and
