Abstract

Wirelessly-linked, distributed resource control (RCS1-RCSn, RCSB, RCC, ARM) supports a wireless communication system (50) for operation in non-exclusive spectrum (24-29). An available resource map (ARM) contains resource availability information gathered by mobile stations (MS1-MSn), and a wired communication channel supports sharing of resource control information among fixed-site stations (BS).

Claims

1. A wireless mobile communication apparatus, comprising:

a wireless communication interface;

a session manager coupled to said wireless communication interface and cooperable therewith for transmitting a request to establish a wireless communication session with another wireless communication apparatus, said session manager including a resource controller, cooperable with said wireless communication interface, enabled to participate in a mutual agreement with said another wireless communication apparatus whether said wireless communication session will be established, said resource controller, after transmitting said request, for participating in wireless communication of communication information for use in deciding whether said wireless communication session will be established; and

wherein said information indicates whether a further wireless communication apparatus has objected to establishment of said wireless communication session.

2. The apparatus of claim 1, wherein the another wireless communication apparatus is a wireless mobile communication apparatus and said resource controller is cooperable with said wireless communication interface for receiving said information from the another wireless communication apparatus.

3. The apparatus of claim 2, wherein said information is indicative of a likelihood of successful execution of said communication session.

4. The apparatus of claim 3, wherein said information includes one of information indicative of a location of the another wireless mobile communication apparatus, information indicative of wireless communication channel conditions at the another wireless mobile communication apparatus, information indicative of wireless communication resource use in a previous wireless communication session involving the another wireless mobile communication apparatus, and information indicative of operational capabilities of the another wireless mobile communication apparatus.

5. The apparatus of claim 1, wherein the further wireless communication apparatus is a wireless mobile communication apparatus.

6. The apparatus of claim 5, wherein the another wireless communication apparatus is a wireless mobile communication apparatus.

7. The apparatus of claim 5, wherein the another wireless communication apparatus is a fixed-site wireless communication apparatus.

8. The apparatus of claim 1, wherein said resource controller is cooperable with said wireless communication interface for transmitting said information.

9. The apparatus of claim 8, wherein said information indicates an intention to establish said communication session.

10. The apparatus of claim 9, wherein the another wireless communication apparatus is a wireless mobile communication apparatus.

11. The apparatus of claim 9, wherein the another wireless communication apparatus is a fixed-site wireless communication apparatus.

12. A wireless mobile communication apparatus, comprising:

a wireless communication interface;

a session manager coupled to said wireless communication interface and cooperable therewith for receiving request from another wireless communication apparatus to establish a wireless communication session with said another wireless communication apparatus, said session manager including a resource controller cooperable with said wireless communication interface, enabled to participate in a mutual agreement with said another wireless communication apparatus, whether said wireless communication session will be established, said resource controller, after receiving said request, for participating in wireless communication of communication information for use in deciding whether said wireless communication session will be established; and

wherein said information indicates whether a further wireless communication apparatus has objected to establishment of said communication session.

13. The apparatus of claim 12, wherein said resource controller is cooperable with said wireless communication interface for transmitting said information.

14. The apparatus of claim 13, wherein the another wireless communication apparatus is a wireless mobile communication apparatus an d said resource controller is cooperable with said wireless communication interface for transmitting said information to the another wireless communication apparatus.

15. The apparatus of claim 14, wherein said information is indicative of a likelihood of successful execution of said communication session.

16. The apparatus of claim 15, wherein said information includes one of information indicative of a location of the wireless mobile communication apparatus, information indicative of wireless communication channel conditions at the wireless mobile communication apparatus, information indicative of wireless communication resource use in a previous wireless communication session involving the wireless mobile communication apparatus, and information indicative of operational capabilities of the wireless mobile communication apparatus.

17. The apparatus of claim 13, wherein said information indicates an intention to establish said communication session.

18. The apparatus of claim 17, wherein the another wireless communication apparatus is a wireless mobile communication apparatus.

19. The apparatus of claim 17, wherein the another wireless communication apparatus is a fixed-site wireless communication apparatus.

20. The apparatus of claim 12, wherein the further wireless communication apparatus is a wireless mobile communication apparatus.

21. The apparatus of claim 20, wherein the another wireless communication apparatus is a wireless mobile communication apparatus.

22. The apparatus of claim 20, wherein the another wireless communication apparatus is a fixed-site wireless communication apparatus.
