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

1-37. -37. (canceled)

38. A device, comprising:

a transmitter for broadcasting a request within the ad-hoc network;

a receiver for receiving replies comprising portions of a message hosted as separate portions by a plurality of devices that are participating in an ad-hoc network and are located within an area identified by the message; and

a processor for reproducing the message from the received portions.

39. A device as claimed in claim 38, wherein the request comprises an ID identifying the device or its user.

40. A device as claimed in claim 38, wherein the request comprises an ID identifying the device or the user of a device from which a message is expected.

41. A device as claimed in claim 38, wherein the request additionally comprises an address for the device.

42. A device as claimed in claim 38, wherein the processor uses sequence numbers within the received portions for combining the message portions in the correct order.

43. A device as claimed in claim 38, wherein the message portions have been redundantly encoded and the processor uses a decoder to enable the message to be reproduced although not all of the portions of the message have been received.

51. A device as claimed in claim 38, wherein the transmitter is configured to configured to transmit a further message for reception by another device, wherein the processor is configured to add location information to the further message, before transmission, and wherein the location information identifies an area within which the further message is to be hosted for reception by the another device.

52. A device as claimed in claim 38, wherein the processor is configured to create separate data structures by dividing a further message into a plurality of separate further message portions and adding the same location information to each of the separate further message portions, and the transmitter is configured to transmit the data structures separately for storage in devices located within the area.

54. A device as claimed in claim 38 for transmitting a further message for reception by another device, comprising:

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

a transmitter for transmitting the further message, with the location information.

55. A device as claimed in claim 38 that is operable as a device selected from a group comprising:

a mobile radio transceiver device;

a mobile phone; and

a personal digital assistant.

44. An ad-hoc network of participating devices operable to locate the portions of a message within an area defined by each of the message portions, wherein the message portions are in distributed storage amongst participating devices within the area and each participating device is arranged so that when it moves from inside to outside the area the message portion(s), defining the area, stored by that device are transferred to another device within the area.

45. 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 an ad-hoc network and are located within an area identified by the message; and

reproducing the message from the received portions.

46. A method as claimed in claim 45, wherein the request comprises an ID identifying a device or its user.

47. A method as claimed in claim 45, wherein the request comprises an ID identifying a device or a user of a device from which a message is expected.

48. A method as claimed in claim 45, wherein the request additionally comprises an address for a device.

49. A method as claimed in claim 45, wherein the received portions of the message have sequence numbers used for combining the message portions in the correct order.

50. A method as claimed in claim 45, 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.

53. A method as claimed in 45, 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.
