Claim Text:
1. A method, performed by a radio network node in a wireless communication network, for detecting the load on transport network interfaces as an input for a radio resource management (RRM) function, wherein the radio network node is part of a transport network, functions as a serving radio network node, and is responsible for performing the RRM function, the method comprising: the serving radio network node identifying a transport network interface from which transport load measurements are required for the RRM function, and a target radio network node associated with the identified transport network interface; the serving radio network node requesting the target radio network node to perform transport load measurements on the identified transport network interface, the request specifying measurement parameters and reporting conditions for the target radio network node; the serving radio network node receiving the measurement results from the target radio network node when the reporting conditions are fulfilled; the serving radio network node basing performance of the RRM function at least partly on the received measurement results; and the serving radio network node storing long-term network transport load data that is used to identify a mismatch between loads on the air interface and the transport network interface; wherein the transport network includes resources on a fixed part of a radio access network portion of the wireless communication network.
