Abstract

A device for transmitting a message for reception by another device, comprising: a processor for adding location information to the message, before transmission, wherein the location information identifies an area within which the message is to be hosted for reception by the other device; and a transmitter for transmitting the message, with the location information.

Claims

1. A device, comprising:

at least one processor; and

at least one memory including computer program code for one or more programs,

the at least one memory and the computer program code configured to, with the at least one processor, cause the device to perform at least the following,

determining to transmit a request within an ad-hoc network;

receiving replies to the request comprising portions of a message, hosted as separate portions by a plurality of devices that are participating in the ad-hoc network and are located within an area, wherein each of the separate portions of the message contains location information identifying the area; and

reproducing the message from the received portions.

2. A device as claimed in claim 1, wherein the request comprises an ID identifying the device or its user.

3. A device as claimed in claim 1, wherein the request comprises an ID identifying the device or the user of a device from which a message is expected.

4. A device as claimed in claim 1, wherein the request additionally comprises an address for the device.

5. A device as claimed in claim 1, wherein the processor uses sequence numbers within the received portions for combining the message portions in the correct order.

6. A device as claimed in claim 1, wherein the message portions have been redundantly encoded and are decoded to enable the message to be reproduced although not all of the portions of the message have been received.

7. A device as claimed in claim 1, wherein the device is caused to further perform,

transmitting a further message for reception by another device, and

adding location information to the further message, before transmission, wherein the location information identifies an area within which the further message is to be hosted for reception by the another device.

8. A device as claimed in claim 1, wherein the device is caused to further perform,

generating separate data structures by dividing a further message into a plurality of separate further message portions,

adding the same location information to each of the separate further message portions, and

transmitting the data structures separately for storage in devices located within the area.

9. A device as claimed in claim 1, wherein the device is caused to further perform,

adding location information to a further message, before transmission, wherein the location information identifies an area within which the further message is to be made available for reception by another device;

and

transmitting the further message, with the location information.

10. A device as claimed in claim 1, wherein the device comprises one of a mobile radio transceiver device, a mobile phone, or a personal digital assistant.

11. A method comprising:

transmitting a request in an ad-hoc network;

receiving replies to the request comprising portions of a message hosted as separate portions by a plurality of devices that are participating in the ad-hoc network and are located within an area, wherein each of the separate portions of the message contains location information identifying the area; and

reproducing the message from the received portions.

12. A method as claimed in claim 11, wherein the request comprises an ID identifying a device or its user.

13. A method as claimed in claim 11, wherein the request comprises an ID identifying a device or a user of a device from which a message is expected.

14. A method as claimed in claim 11, wherein the request additionally comprises an address for a device.

15. A method as claimed in claim 11, wherein the received portions of the message have sequence numbers used for combining the message portions in the correct order.

16. A method as claimed in claim 11, wherein the message portions have been redundantly encoded and are decoded to enable the message to be reproduced although not all of the portions of the message have been received.

17. A method as claimed in 11, further comprising:

adding location information to a further message, before transmission, identifying an area within which the further message is to be hosted; and

transmitting the further message, with the location information.
