Abstract

A communications system comprises at least one beacon device (12, 14) capable of wireless message transmission and at least one portable device (10) capable of receiving such a message transmission. The beacon (12) is arranged to broadcast a series of inquiry messages (60) each in the form of a plurality of predetermined data fields (INQ) arranged according to a first communications protocol, such as Bluetooth. For the delivery of additional data via broadcast, the beacon (12) adds to each inquiry message prior to transmission an additional data field (BCD) carrying broadcast data, with the portable device (10) receiving the transmitted inquiry messages and reading the broadcast data from the additional data field.

Claims

1. A communications system comprising at least one beacon device capable of wireless message transmission and at least one portable device capable of receiving such a message transmission, wherein the beacon is arranged to broadcast a series of inquiry messages each in the form of a plurality of predetermined data fields arranged according to a first communications protocol, wherein the beacon is further arranged to add to each inquiry message prior to transmission an additional data field, and wherein the at least one portable device is arranged to receive the transmitted inquiry messages and read data from said additional data field.

2. A system as claimed in claim 1, wherein the beacon is arranged to add said additional data field at the end of a respective inquiry message.

3. A system as claimed in claim 1, wherein the beacon is arranged to include an indication in one of said predetermined data fields, said indication denoting the presence of said additional data field.

4. A system as claimed in claim 1 wherein said first communications protocol comprises Bluetooth messaging.

5. A system as claimed in claim 4, wherein the beacon is configured to broadcast a series of inquiry messages on a predetermined clocked succession of frequencies, with clock information for said beacon being included in data carried by said additional data field.

6. A system as claimed in claim 1, wherein said additional data field carries at least 64 bits of data.

7. A system as claimed in claim 1, wherein the beacon is arranged to include in a message first comparison data, the portable device further comprising storage means holding second comparison data and comparator means arranged to identify when there is a match between the first and second comparison data and present the data read from the additional data field, otherwise to not present the data.

8. A system as claimed in claim 7, further comprising means for generating said second comparison data from user profiling of the portable device user.

9. A system as claimed in claim 7, wherein said comparator means is a programmable device operable to perform, in synchronous or overlapping manner, comparisons between respective sets of first and second comparison data.

10. A mobile communication device for use in the system of claim 1, the device comprising a receiver capable of receiving a short-range wireless inquiry message including a plurality of data fields according to a first communications protocol, means for determining when an additional data field has been added to said plurality of data fields, and means for reading data from such an additional data field and presenting the same to a user.

11. A beacon device capable of wireless message transmission and for use in a communications system comprising said beacon device and at least one portable device capable of receiving such a message transmission, wherein the beacon is configured to broadcast a series of inquiry messages each in the form of a plurality of predetermined data fields arranged according to a first communications protocol, and to add to each inquiry message prior to transmission an additional data field, such as to enable the at least one portable device arranged to receive the transmitted inquiry messages to read data from said additional data field.

12. A beacon device as claimed in claim 11, arranged to add said additional data field at the end of a respective inquiry message.

13. A beacon device as claimed in claim 11, arranged to include an indication in one of said predetermined data fields, said indication denoting the presence of said additional data field.

14. A beacon device as claimed in claim 11, wherein said first communications protocol comprises Bluetooth messaging configured to broadcast a series of inquiry messages on a predetermined clocked succession of frequencies, with clock information for said beacon being included in data carried by said additional data field.

15. A method for enabling the user of a portable communications device to receive broadcast messages wherein at least one beacon device broadcasts a series of inquiry messages each in the form of a plurality of predetermined data fields arranged according to a first communications protocol, wherein the beacon adds to each inquiry message prior to transmission an additional data field carrying broadcast message data, and wherein the portable device receives the transmitted inquiry messages and reads the broadcast data from said additional data field.

16. A method as claimed in claim 15, wherein the beacon adds said additional data field at the end of a respective inquiry message.

17. A method as claimed in claim 15, wherein the beacon includes an indication in one of said predetermined data fields, said indication denoting the presence of said additional data field.
