Abstract

The invention relates to a method for uploading a transmission network topology of a radio system and to a radio system implementing the method. The radio system comprises at least one network element and a network management system managing the network elements. The network elements are operatively interconnected by a transmission network realized by means of transmission circuits. Information between the network elements is transmitted in frames that are divided into time slots. When a transmission circuit is changed then software of the network elements marks the changed transmission circuit as changed, and the network management system is informed of the changed circuit, whereafter the software of the network element removes the marking from the changed circuits.

Claims

1. A method for uploading a transmission network topology of a radio system comprising:

managing, by a network management system, at least one network element, the at least one network element being operatively interconnected by a transmission network realized by transmission circuits,

transmitting information between the at least one network element in frames that are divided into time slots, wherein when a transmission circuit is changed then software of the at least one network element marks the changed transmission circuit as changed,

informing the network management system of the changed circuit, wherein the network management system is informed of the changed circuit by a response from the software of the at least one network element to a read request from the network management system, and whereafter

removing, by the software of the at least one network element, the marking from the changed circuit.

2. The method as claimed in claim 1, wherein the software in the at least one network element comprises application software of the at least one network element that changes a transmission circuit and a management software that marks the changed transmission circuit as changed.

3. The method as claimed in claim 1, wherein the network management system is informed of the changed circuit by a notification sent from the software of the at least one network element.

4. The method as claimed in claim 1, wherein the marking is removed from the changed circuit only after the network management system is informed of the changed circuit.

5. The method as claimed in claim 1, wherein as by default all transmission circuits are marked as changed in the software of the at least one network element.

6. The method as claimed in claim 1, wherein the radio system comprises at least one cross-connection unit between at least two network elements for realizing cross-connections needed to establish the transmission circuits, and while configuring the cross-connections, class-marks are allocated for transmission circuits, a class-mark comprising an application type for defining the type of the software that performs the configuration, a priority for defining the order according to which the configuration is performed, and a label for defining the name of the transmission circuit.

7. A radio system comprising:

at least one network element, and

a network management system managing the at least one network element, the at least one network element being operatively interconnected by a transmission network realized by means of transmission circuits, and information between the at least one network element is transmitted in frames that are divided into time slots, wherein the at least one network element comprises software performing the following operation;

when a transmission circuit is changed then software of the at least one network element marks the changed transmission circuit as changed, and the radio system comprises software for informing the network management system of the changed circuit, wherein the network management system is informed of the changed circuit by a response from the software of the at least one network element to a read request from the network management system, whereafter the software of the at least one network element removes the marking from the changed circuits.

8. The radio system as claimed in claim 7, wherein the software in the at least one network element comprises an application software of the at least one network element that changes a transmission circuit and management software that marks the changed transmission circuit as changed.

9. The radio system as claimed in claim 7, wherein the network management system is informed of the changed circuit by a notification sent from the software of the at least one network element.

10. The radio system as claimed in claim 7, wherein the marking is removed from the changed circuit only after the network management system is informed of the changed circuit.

11. The radio system as claimed claim 7, wherein by default all transmission circuits are marked as changed in the software of the at least one network element.

12. The radio system as claimed in claim 7, wherein the radio system comprises at least one cross-connection unit between at least two network elements for realizing cross-connections needed to establish the transmission circuits, and while configuring the cross-connections, class-marks are allocated for transmission circuits, a class-mark comprising an application type for defining the type of the software that performs the configuration, a priority for defining the order according to which the configuration is performed, and a label for defining the name of the transmission circuit.
