Abstract

A communications network comprises a plurality of beacons (10) for transmitting data to mobile receivers within range, each beacon (10) storing local data items for transmission to the mobile receivers which is dependent on the location of the beacon. A central controller (14) is provided for updating the local data items stored in the beacons. The central controller (14) enables beacons to be identified which require updating in response to a desired change in a local data item. This system uses a central controller that can manage the control and configuration and software running on the remote beacons. The central controller can efficiently monitor and control the content information running on each beacon to ensure the network is providing up-to-date alerts and messages to users.

Claims

1. A communications network comprising:

a plurality of transmitters, each for transmitting data to mobile receivers within range of the transmitter, each transmitter storing local data items for transmission to the mobile receivers which is dependent on the location of the transmitter; and

a central controller for updating the local data items stored in the transmitters of the network,

wherein the central controller comprises means for identifying the local data stored within each transmitter, thereby enabling transmitters to be identified which require updating in response to a desired change in a local data item.

2. A system as claimed in claim 1, wherein the transmitter is for transmitting using short range RF.

3. A system as claimed in claim 1, wherein each transmitter comprises a transceiver enabling bidirectional system communication between the transmitter and the central controller.

4. A system as claimed in claim 3, wherein the bidirectional system communication is using a mobile telephony connection.

5. A system as claimed in claim 4, wherein the mobile telephony connection is a cellular or satellite radio connection.

6. A system as claimed in claim 1, wherein each transmitter comprises a transceiver enabling bidirectional client communication between the transmitter and the mobile receivers.

7. A system as claimed in claim 6, wherein the bidirectional client communication is using a Bluetooth connection.

8. A system as claimed in claim 1, wherein the central controller comprises a database identifying all local data items stored in each transmitter and the operative states of each beacon.

9. A system as claimed in claim 1, wherein the transmitters are within range of at least one other transmitter such that update messages can be relayed between transmitters.

10. A system as claimed in claim 9, wherein some or all of the transmitters are within range of at least one other transmitter for short range RF communication.

11. A system as claimed in claim 1, wherein the central controller is also for updating the configurations of the transmitters.

13. A method as claimed in claim 12, wherein the identification is carried out in response to an update in a local data item.

14. A method as claimed in claim 12, wherein the identification is carried out periodically.

15. A method as claimed in claim 12, wherein the updated local data items are transmitted to the identified transmitters by a mobile telephony link between the central controller and the transmitters.

16. A method as claimed in claim 12, wherein the updated local data items are transmitted to the identified transmitters by a mobile telephony link between the central controller at least one transmitter, and by further wireless transmission between transmitters.

17. A method as claimed in claim 16, wherein the further wireless transmission is using Bluetooth, 802.11 or Zigbee.

18. A method as claimed in claim 12, wherein the transmitters of the network which require updating as a result of software upgrades or required configuration changes are also identified in the central controller.

19. A computer program code means for performing the method of claim 12 when run on a computer.

20. A computer readable means storing a computer program code means as claimed in claim 19.

12. A method of controlling a communications network comprising:

providing a plurality of transmitters with software comprising local data items selected in dependence on the location of the transmitter and for transmission to mobile receivers within range of the transmitter; and

subsequently identifying in a central controller the transmitters of the network which require updating as a result of updates to local data items; and

transmitting updated local data items to the identified transmitters.
