A first node (2) of a first network using a first radio access technology signals (SI) a second node (3) of a second network using a second radio access technology start and stop of a test data session and to send test data packets to a UE (1) in an aggregation mode via the second node (3) in the test data session. The UE (1) is associated with the second node (3). The test data packets comprise payload and an aggregation header including an indication that the payload comprises test data. The first node (2) determines (S4) a service level of the UE (1) with respect to the second node (3) based on a report on a throughput of the test data packets sent by the second node (3) in the test data session. |
