Abstract

The present invention relates to a method in a mobile device and a mobile device for low power identification of its position in an indoor environment, in which beacon transmitters of a beacon system are present. The device receives a notification from at least one of the beacon transmitters of the beacon system that notifies the mobile device that it is within the range of the beacon system. Thus it is the beacon transmitters that perform the continuous scanning to identify if the mobile device is within range and not the mobile device itself. This will reduce the power consumption of the mobile device substantially. The mobile device will than request that the beacon transmitters within range to send data pertaining to their position, and then determine its position by performing calculations based on such data.

Claims

1. A method in a mobile device for low power identification of its position in an indoor environment, in which beacon transmitters of a beacon system are present, comprising the steps of

receiving a notification from at least one of the beacon transmitters of the beacon system that notifies the mobile device that it is within the range of the beacon system,

requesting that the beacon transmitters that are within the range of the mobile device send data pertaining to their position, and

determining its position by performing calculations based on such data.

2. The method according to claim 1, wherein the step of receiving the notification further includes the step of

receiving the notification from the beacon transmitter via a positioning server.

3. The method according to claim 1, wherein the calculation is based on range measurements performed by the mobile device.

4. The method according to claim 1, wherein the calculation is based on range measurements performed by the beacon transmitters.

5. The method according to claim 1,

wherein all communication between the mobile device and the beacon transmitters is performed via a positioning server.

6. A mobile device for low power identification of its position in an indoor environment, in which beacon transmitters of a beacon system are present, said mobile device being configured to execute the steps of

receiving a notification from at least one of the beacon transmitters of the beacon system that notifies the mobile device that it is within the range of the beacon system,

requesting the beacon transmitters that are within the range of the mobile device to send data pertaining to their position, and

determining its position by performing calculations based on such data.

7. A mobile device according to claim 6, wherein the mobile device is further configured to execute the step of receiving the notification from the beacon transmitter via a positioning server.

8. A mobile device according to claim 6, wherein the mobile device is configured to perform range measurements on which the calculations are based.

9. A mobile device according to claim 6, wherein the mobile device is configured to receive range measurements from the beacon transmitters on which the calculations are based.

10. A mobile device according to claim 6,

wherein the mobile device is configured to perform all communication with the beacon transmitters via a positioning server.
