Abstract

The application describes a network comprising transceivers (1..6) linked in a network topology. The positions of the transceivers in the network topology are changed in dependence on the loads on the end-to-end connections (VC1..VC5) between the transceivers in the network. A configuration is chosen to give efficient use of the capacity available in the network. Each time that a new end-to-end connection (VC) within the network is set up the positions of the transceivers (1..6) are changed such that the network remains optimized.

Claims

1. Communication network comprising transceivers (1..6) linked in a network topology, and reconfiguration means (7) for obtaining an optimal configuration of the transceivers (1..6) in the network topology by changing positions of the transceivers in the network in dependence on loads carried by end-to-end connections (VC1..VC5) between the transceivers (1..6) and the number of links associated with said end-to-end connections.

2. Communication network according to claim 1 in which the optimized configuration of the transceivers in the network topology is obtained by optimizing a load weighted sum of frequency utilisation factors of the end-to-end connections (VC1..VC5) in the network.

3. Communication network according to claim 1, in which the transceivers (1..6) are arranged for radio communication with each other and the reconfiguration means (7) comprises channel allocation means for allocation of the radio channels to the transceivers, (1..6) by changing the allocation of radio channels to the transceivers (1..6).

4. Communication network according to claim 1 characterized in that, the transceivers (1 ..6) are arranged for communication with each other using ATM-packets.

5. Communication network according to claim 1 characterized in that, the reconfiguration means are arranged to change the positions of the transceivers (1..6) when an end-to-end connection (VC1 ..VC5) is set up or broken down.

6. Communication network according to claim 1 characterized in that, the transceivers (1..6) are arranged for sending signalling information (inf2) to the reconfiguration means (7) about setting up and breaking down end-to-end connections and about the load on end-to-end connections.

7. Transceiver (1..6) for use in a network according to claim 1, characterized in that, the transceiver (1..6) is arranged for sending signalling information (inf2) to the reconfiguration means (7) about setting up and breaking down end-to-end connections and about the load on end-to-end connections.

8. Reconfiguration arrangement (7) for use in a network according to claim 1 in which the reconfiguration (7) means is arranged for obtaining an optimal configuration of the transceivers (1..6) in dependence on loads on end-to-end connections (VC1..VC..5) between the transceivers (1..6).
