Abstract

In a cellular communication network, radio planning information is provided in a first control node that controls a plurality of first fixed-site radio transceivers which define a plurality of first cells in the cellular communication network. Without network operator support, the radio planning information is communicated from the first control node to a second control node that controls a plurality of second fixed-site radio transceivers which define in the cellular communication network a plurality of second cells including at least one second cell that is located adjacent to at least one of the first cells.

Claims

1. A method of performing radio planning in a cellular communication network, comprising:

providing radio planning information including at least one frequency assignment for border cells in a first control node that controls a plurality of first fixed-site radio transceivers which define a plurality of first cells in the cellular communication network;

without network operator support, communicating the radio planning information including at least one frequency assignment for border cells from the first control node to a second control node that controls a plurality of second fixed-site radio transceivers which define in the cellular communication network a plurality of second cells including at least one said second cell that is located adjacent to at least one of the first cells;

receiving an incoming message from second control node;

updating a database responsive to the incoming message; and

forwarding the incoming message to a third control node.

2. The method of claim 1, wherein said providing step includes the first control node executing a radio planning algorithm, and using the radio planning algorithm to produce the radio planning information including at least one frequency assignment for border cells.

3. The method of claim 1, wherein said providing step includes executing a radio planning algorithm externally of the first control node, and communicating the radio planning information including at least one frequency assignment for border cells to the first control node.

4. The method of claim 1, wherein said communicating step includes communicating the radio planning information including at least one frequency assignment for border cells to a plurality of control nodes that control respective pluralities of fixed-site radio transceivers which define in the cellular communication network respective pluralities of cells.

5. The method of claim 1, wherein said communicating step includes communicating said radio planning information including at least one frequency assignment for border cells from the first control node to the second control node immediately and automatically in response to said providing step.

6. The method of claim 1, including communicating radio planning information including at least one frequency assignment for border cells from the second control node to the first control node without network operator support.

7. The method of claim 6, including storing the radio planning information including at least one frequency assignment for border cells communicated from the second control node to the first control node in a database of the first control node.

8. In an apparatus for controlling a plurality of first fixed-site radio transceivers that define a plurality of first cells of a cellular communication network, an improvement comprising:

a communications interface for communicating radio planning information, said communications interface including an input for receiving the radio planning information, and further including an output for, without network operator support, communicating the radio planning information including at least one frequency assignment for border cells to a further apparatus that controls a plurality of second fixed-site radio transceivers that define in the cellular communication network a plurality of second cells including at least one said second cell that is located adjacent to at least one of said first cells; and

a message handler coupled between said input and said output for providing a message at said output in response to said radio planning information including at least one frequency assignment for border cells received at said input, for receiving an incoming message from second control nodes, updating a database responsive to the incoming message, and forwarding the incoming message to a third control node.

9. The apparatus of claim 8, wherein said message handler is operable to produce any selected one of a plurality of possible messages in response to said radio planning information.

10. The apparatus of claim 8, wherein said output is for coupling to a communication link coupled to the further apparatus.

11. The apparatus of claim 8, including a radio planner coupled to said input of said communications interface for providing the radio planning information to said input.

12. The apparatus of claim 8, wherein said input of said communications interface is for receiving radio planning information including at least one frequency assignment for border cells from a source external to said apparatus.

13. The apparatus of claim 8, wherein said communications interface has a further input for receiving radio planning information including at least one frequency assignment for border cells from the further apparatus without network operator support.

14. The apparatus of claim 13, including a database coupled to said communications interface for storing therein the radio planning information including at least one frequency assignment for border cells received by said communications interface from the further apparatus.

15. The apparatus of claim 8, wherein said apparatus is a local office network switch and the cellular communication network is a local office network.

16. The apparatus of claim 8, wherein said apparatus is a base station controller and the cellular communication network is a GSM network.

17. The apparatus of claim 8, wherein said apparatus is a mobile services switching center, and wherein said cellular communication network is one of an AMPS network and a PDC network.

18. The apparatus of claim 8, wherein said output communicates the radio planning information including at least one frequency assignment for border cells to the further apparatus immediately and automatically in response to receipt of the radio planning information at said input.

19. The apparatus of claim 8, wherein said radio planning information includes information including at least one frequency assignment for border cells indicative of a neighboring cell relationship between the at least one first cell and the at least one second cell for facilitating handoff of a mobile station between the at least one first cell and the at least one second cell.

20. The apparatus of claim 19, wherein the radio planning information including at least one frequency assignment for border cells includes information indicative of one of establishment and removal of the neighboring cell relationship.

21. The apparatus of claim 8, wherein said radio planning information including at least one frequency assignment for border cells includes a control frequency used in the at least one first cell.

22. A method for radio planning in a cellular communications network, comprising the steps of:

determining at a first control node other than a network operator support node at least one of a frequency assignments and adaptive frequency allocation for cells supported by the first control node in the cellular communications network;
