Abstract

In order to encourage listeners to remain tuned to a particular radio station, loyal listeners are rewarded by being enabled to use a service system accessible via a data-capable bearer service of a communications infrastructure. This is achieved by periodically including, amongst the material broadcast by the radio station, a variable-value access code and then only servicing request to the service system that include the most recent value of the access code. The listener takes advantage of the service by extracting the access code value from the received radio signal and including it in a service request. Typically, the service is a location-based service accessible by a mobile listener via a cellular radio network.

Claims

1. A method of controlling use of a service system accessible via a data-capable bearer service of a communications infrastructure, the method comprising the steps of:

(a) broadcasting content via a broadcast radio channel and periodically including a variable-value access code;

(b) receiving service requests at the service system and, at least for a subset of the requests, only servicing a request where the request is accompanied by a recently broadcast access-code value.

2. A method according to claim 1, wherein said request is only serviced if the accompanying access-code value is the most recently broadcast value.

3. A method according to claim 1, wherein in step (a) the code is accompanied by the access address of the service system.

4. A method according to claim 1, wherein the access address of the service system is pre-established for the broadcast radio channel concerned.

5. A method according to claim 1, wherein in step (a) the access code is included at least every minute.

6. A method according to claim 1, wherein in step (a) the access code is included at least every five seconds.

7. A method according to claim 1, wherein in step (a) the access code is included during advertisements forming part of said content.

8. A method according to claim 1, wherein in step (a) the access code is included at random intervals.

9. A method according to claim 1, wherein in step (a) the access code is included with content associated with a party providing or sponsoring the service system.

10. A method according to claim 1, wherein the service system is run or sponsored by the operator of the broadcast radio channel.

11. A method according to claim 1, wherein the service provided by the service system is a location-based service, the service request either including a request location or giving access authority to enable the service system to obtain the location of the source of the service request from a location server.

12. A method according to claim 1, wherein the communications infrastructure comprises a cellular radio network interfacing with the Internet, the service system being connected to the Internet whereby to receive service requests from mobile users having connectivity to the cellular radio network.

14. A method according to claim 1, wherein the access-code value included in the request is the most recently received access-code value.

16. Apparatus according to claim 15, wherein the access-code value included in the request is the most recently received access-code value.

18. A method according to claim 17, wherein the service request is only serviced where the access-code value included in the request is the most recently broadcast access-code value.

13. A method of obtaining use of a service system accessible via a data-capable bearer service of a communications infrastructure, the method comprising the steps of:

(a) receiving a broadcast radio channel that periodically includes, along with the content being broadcast, a variable-value access code;

(b) extracting the access code from the received broadcast radio channel;

(c) sending a service request to the service system via said data-capable bearer service, the service request including a recently broadcast access-code value.

15. Apparatus for obtaining use of a service system accessible via a data-capable bearer service of a communications infrastructure, the apparatus comprising:

a radio receiver for receiving broadcast content that periodically includes a variable-value access code;

an extraction subsystem for extracting the access code from the received broadcast radio channel;

a request subsystem for generating a service request and sending it to the service system via said data-capable bearer service, the service request including a recently broadcast access-code value as extracted by the extraction subsystem.

17. A method of providing for controlled use of a service system accessible via a data-capable bearer service of a communications infrastructure, the method comprising the steps of:

(a) broadcasting content via a broadcast radio channel and periodically including a variable-value access code;

(b) receiving the broadcast radio channel;

(c) extracting the access code from the received broadcast radio channel;

(d) sending a service request to the service system via said data-capable bearer service, the service request including a recently broadcast access-code value; and

(e) receiving the service request at the service system and only servicing the request where the request is accompanied by a recently broadcast access-code value.
