Nodes and methods for monitoring of communication
First Claim
1. A network node for a telecommunication network, wherein the network node comprises:
- a receiving circuit adapted to receive a monitoring control message, the monitoring control message comprising an identifier relating to a subscriber whose communication is to be monitored;
a processing circuit adapted to determine one or more filter parameters for filtering communication relating to the subscriber based on the received monitoring control message,wherein the one or more filter parameters comprise one or more dynamic identifiers and/or transport layer information in relation to at least a portion of the communication relating to the subscriber handled by the network node, andwherein the dynamic identifiers are communication-related identifiers that are generated for the at least a portion of the communication relating to the subscriber handled by the network node; and
a sending circuit adapted to send a filter parameter message indicative of the determined one or more filter parameters to a monitoring node separate from the network node for filtering of the communication relating to the subscriber in accordance with the one or more filter parameters.

Abstract
A network node for a telecommunication network is provided. The network node includes a receiving unit adapted to receive a monitoring control message. The monitoring control message includes an identifier relating to a subscriber whose communication is to be monitored. A processing unit is adapted to determine one or more filter parameters for filtering communication relating to the subscriber based on the received monitoring control message. The network node also includes a sending unit adapted to send a filter parameter message indicative of the determined one or more filter parameters to a monitoring node separate from the network node for filtering of the communication relating to the subscriber in accordance with the one or more filter parameters.

7. A monitoring node for a telecommunication network comprising a network node which is separate from the monitoring node, wherein the monitoring node comprises:
-
a receiving circuit adapted to receive a filter parameter message indicative of one or more filter parameters for filtering communication relating to a subscriber in the telecommunication network, wherein the one or more filter parameters comprise one or more dynamic identifiers and/or transport layer information in relation to at least a portion of the communication relating to the subscriber handled by the network node, and wherein the dynamic identifiers are communication-related identifiers that are generated for the at least a portion of the communication relating to the subscriber handled by the network node; a processing circuit adapted to filter said communication based on the received one or more filter parameters; and an output circuit adapted to output the filtered communication. - View Dependent Claims (8, 9, 10, 11, 12, 14)

15. A method of operating a network node for a telecommunication network, wherein the method comprises:
-
receiving a monitoring control message, the monitoring control message comprising an identifier relating to a subscriber whose communication is to be monitored; determining one or more filter parameters for filtering communication relating to the subscriber based on the received monitoring control message, wherein the one or more filter parameters comprise one or more dynamic identifiers and/or transport layer information in relation to at least a portion of the communication relating to the subscriber handled by the network node, and wherein the dynamic identifiers are communication-related identifiers that are generated for the at least a portion of the communication relating to the subscriber handled by the network node; and sending a filter parameter message indicative of the determined one or more filter parameters to a monitoring node separate from the network node for filtering of the communication relating to the subscriber in accordance with the one or more filter parameters. - View Dependent Claims (16, 17, 18)

19. A method of operating a monitoring node for a telecommunication network comprising a network node which is separate from the monitoring node, wherein the method comprises:
-
receiving a filter parameter message indicative of one or more filter parameters for filtering communication relating to a subscriber in the telecommunication network, wherein the one or more filter parameters comprise one or more dynamic identifiers and/or transport layer information in relation to at least a portion of the communication relating to the subscriber handled by the network node, and wherein the dynamic identifiers are communication-related identifiers that are generated for the at least a portion of the communication relating to the subscriber handled by the network node; filtering said communication based on the received one or more filter parameters; and outputting the filtered communication. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
