Abstract

A method and apparatus for sharing information among a plurality of wireless transmit/receive units (WTRUs) in a wireless communication system comprises a first WTRU in the wireless communication system broadcasting a request for desired information. A second WTRU in the wireless communication system searches a memory of the second WTRU for the desired information and responds to the broadcast by indicating to the first WTRU that it is capable of providing the desired information. The first WTRU requests that the second WTRU provide the desired information, and the second WTRU retrieves the desired information from the memory in the second WTRU and sends the desired information to the first WTRU.

Claims

1. A method for sharing information among a plurality of wireless transmit/receive units (WTRUs) in a wireless communication system, comprising:

a first WTRU in the wireless communication system broadcasting a request for desired information;

a second WTRU in the wireless communication system searching a memory of the second WTRU for the desired information; and

the second WTRU responding to the broadcast by indicating to the first WTRU that it is capable of providing the desired information.

2. The method of claim 1, further comprising:

the first WTRU requesting that the second WTRU provide the desired information; and

the second WTRU retrieving the desired information from the memory in the second WTRU and sending the desired information to the first WTRU.

3. The method of claim 1, further comprising the second WTRU sending data about the desired information to the first WTRU.

4. The method of claim 3, wherein the data about the desired information includes a time stamp on the desired information.

5. The method of claim 4, further comprising other WTRUs in the wireless communication network indicating to the first WTRU that they are capable of providing the desired information.

6. The method of claim 5, further comprising the other WTRUs sending data about the desired information to the first WTRU.

7. The method of claim 6, wherein the data about the desired information includes a time stamp on the desired information.

8. The method of claim 7, further comprising the first WTRU selecting a particular one of the WTRUs from which to receive the desired information.

9. The method of claim 8, wherein the particular WTRU is the first WTRU that conveys its capability to provide the desired information.

10. The method of claim 8, wherein the first WTRU selects a particular WTRU that is the least number of hops away from the first WTRU.

11. The method of claim 8, wherein the particular WTRU contains the most recent time stamp.

12. The method of claim 8, further comprising:

the first WTRU requesting that the particular WTRU provide the desired information; and

the particular WTRU retrieving the desired information from the memory in the particular WTRU and sending the desired information to the first WTRU.

13. In a wireless communication system comprising a plurality of wireless transmit/receive units (WTRUs), each WTRU comprising:

a transmitter;

a receiver; and

a processor in communication with the transmitter and the receiver, wherein an application for sharing information with other ones of the WTRUs in the wireless communication system runs on the processor, the transmitter broadcasts a request for desired information, the receiver receives a first signal from a particular one of the other WTRUs indicating that the particular WTRU is capable of providing the desired information, the transmitter requests the particular WTRU to provide the desired information, and the receiver receiving the desired information from the particular WTRU.

14. The WTRU of claim 13, wherein each WTRU further comprises a memory in communication with the processor.

15. The WTRU of claim 14, wherein the desired information is stored in the memory.

16. The WTRU of claim 13, wherein each WTRU further comprises an antenna in communication with the transmitter and the receiver.

17. The WTRU of claim 13, further comprising a browser in communication with the processor.

18. The WTRU of claim 17, wherein the application for sharing information runs on the processor as a plug in application to the browser.

19. In a wireless communication system comprising a plurality of wireless transmit/receive units (WTRUs), each WTRU including an integrated circuit (IC) comprising:

a transmitter;

a receiver; and

a processor in communication with the transmitter and the receiver, wherein an application for sharing information with other ones of the WTRUs in the wireless communication system runs on the processor, the transmitter broadcasts a request for desired information, the receiver receives a first signal from a particular one of the other WTRUs indicating that the particular WTRU is capable of providing the desired information, the transmitter requests the particular WTRU to provide the desired information, and the receiver receiving the desired information from the particular WTRU.

20. The IC of claim 19, further comprising a memory in communication with the processor.

21. The IC of claim 20, wherein the desired information is stored in the memory.

22. The IC of claim 19, further comprising an antenna in communication with the transmitter and the receiver.

23. The IC of claim 19, further comprising a browser in communication with the processor.
