Abstract

The present invention concerns a method for filtering incoming calls intended to be implemented by a device in a vehicle, said device previously having sent an emergency call to an emergency call center that manages the emergency calls and said device being in a state awaiting any incoming calls sent by callers. The method is characterized in that it comprises the following steps:

• • identifying the caller of each new incoming call,
  • if the identified caller is an emergency call center, then a communication between the device and an operator in the emergency call center is established, and
  • the device returns to the state of awaiting any incoming calls at the end of the communication.

Claims

1. Method for filtering incoming calls implemented by a device embedded in a vehicle, said device previously having sent an emergency call to an emergency call center that manages the emergency calls and said device being in a state awaiting any incoming calls sent by callers, the method comprising the following steps:

identifying the caller of each new incoming call,

if the identified caller is an emergency call center, then a communication between the device and an operator in the emergency call center is established, and

the device returns to the state of awaiting any incoming calls at the end of the communication,

characterized in that, when said device receives each new incoming call, said device sends a special voice message (M1) to the caller and waits to receive another special message (M2), the caller then being considered to be an emergency call center when the device receives said other special message (M2) before expiry of a predetermined period (T).

2. Method according to claim 1, wherein, once the emergency call center has sent a new incoming call to the device, the emergency call center waits to receive said special voice message (M1).

3. Method according to claim 1, wherein, at the end of this predetermined period (T), said device resends said special message (M1) as long as a predetermined retransmission integer number is not reached.

4. Method according to claim 1, wherein a caller of a new incoming call is identified by the device from a special message received that this caller has sent to the device.

5. Method according to claim 4, wherein this special message bears the number or name of the caller.

6. Method according to claim 5, wherein the device previously records at least one number of an emergency call center and the number of a caller is then compared with each recorded emergency call center number, the caller then being considered to be an emergency call center when his number is identical to one of the recorded numbers.

7. Method according to claim 5, wherein the number of the caller is transmitted from the caller to the device in the form of a voice modulated signal.

9. Computer program product, characterized in that it comprises instructions for implementing the method according to claim 1, when said program is executed by a processor.

10. Storage means that can be read by a computer, characterized in that they store a computer program comprising instructions for implementing the method according to claim 1, when said program is executed by a processor.

8. Device for filtering incoming calls intended to be embedded in a vehicle, said device comprising means for sending an emergency call to an emergency call center that manages the emergency calls, said device being configured, when said device has previously sent an emergency call, to be in a state of awaiting any incoming calls sent by distant callers, said device comprising:

means for identifying the caller of each new incoming call,

means for establishing a communication with an operator of the emergency call center if the identified caller is an emergency call center, and

means for returning to the state of awaiting any incoming calls at the end of the communication,

characterized in that, when said device receives each new incoming call, said device implements;

means for sending a special voice message (M1) to the caller,

means for waiting to receive another special message (M2),

means for considering the caller to be an emergency call center when the device receives said other special message (M2) before expiry of a predetermined period (T).
