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 system for controlling allocation of wireless communication resources, comprising:

a first resource control segment, and a first wireless communication interface connected to said first resource control segment;

a second resource control segment, and a second wireless communication interface connected to said second resource control segment, said second resource control segment and said second wireless communication interface provided together in a wireless mobile communication apparatus;

said first and second wireless communication interfaces cooperable to couple said first and second resource control segments for wireless communication; and

said first and second resource control segments cooperable for making a resource allocation decision with respect to a wireless communication session involving the wireless mobile communication apparatus, said resource allocation decision including a determination to use, or not to use, frequency spectrum other than frequency spectrum utilized by cellular operators, for additional communication between said first and second wireless communication interfaces.

2. The system of claim 1, wherein said resource control segments are cooperable for selecting wireless communication resources for the communication session.

3. The system of claim 1, wherein said resource control segments are cooperable for deciding that a further wireless communication session will be discontinued because the further wireless communication session uses resources already allocated to the first-mentioned wireless communication session.

4. The system of claim 3, wherein said first resource control segment is provided in a further wireless mobile communication apparatus involved in the further communication session.

5. The system of claim 1, wherein said resource control segments are cooperable for deciding that resources allocated for the wireless communication session will be released for use in a further wireless communication session that does not involve the wireless mobile communication apparatus.

6. The system of claim 5, wherein said resource control segments are cooperable for deciding that the further communication session has a higher priority than the first-mentioned communication session to use communication resources currently allocated to the first-mentioned communication session.

7. The system of claim 5, wherein said first resource control segment is provided in a further wireless mobile communication apparatus involved in the further communication session.

8. The system of claim 1, wherein said first resource control segment is provided in a further wireless communication apparatus involved in the wireless communication session.

9. The system of claim 8, wherein the further wireless communication apparatus is a mobile wireless communication apparatus.

10. The system of claim 1, wherein said first and second resource control segments are cooperable for communicating among one another information indicative of a likelihood of successful execution of the communication session.

11. The system of claim 10, wherein said first resource control segment is provided in a further wireless communication apparatus involved in the communication session.

12. The system of claim 11, wherein the further wireless communication apparatus is a mobile wireless communication apparatus.

13. The system of claim 10, 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.

14. The system of claim 10, including an information storage apparatus coupled to said first resource control segment, said information storage apparatus for storing said information.

15. The system of claim 14, wherein said first and second wireless communication interfaces are cooperable for wireless transmission of said information from said second resource control segment to said first resource control segment.

16. The system of claim 14, wherein said information storage apparatus is provided in a data network.

17. The system of claim 16, wherein said data network includes the internet.

18. The system of claim 1, wherein said first and second resource control segments are cooperable for deciding whether communication resources will be allocated for the communication session.

19. The system of claim 1, wherein said first resource control segment is provided in a further wireless mobile communication apparatus.

20. The system of claim 1, wherein said resource control segments are cooperable for determining a distance over which the communication session will be conducted, and are further cooperable for selecting a frequency channel for the communication session based on said distance.

21. The system of claim 20, wherein said resource control segments are cooperable to select for the communication session one of a frequency channel at a relatively lower frequency if the communication session will be conducted over a relatively longer distance and a frequency channel at a relatively higher frequency if the communication session will be conducted over a relatively shorter distance.

22. The system of claim 1, wherein said frequency spectrum other than frequency spectrum utilized by cellular operators implements frequency channels adjacent the frequency channels utilized by cellular operators.

23. The system of claim 1, wherein when said resource allocation decision is to use frequency channels other than frequency channels utilized by cellular operators, frequency channels in the ISM band are selected if available and, if not available, frequency channels having frequencies adjacent said frequencies of said frequency channels utilized by said cellular operators are selected.
