It is provided a core network node (107; 207), e.g. MME, and a first network node(109; 209), e.g. a OAM congestion reporting function node,for managing wireless device associated information, in particular for or as part of congestion handling. The nodes are comprised in a wireless communication network (100; 200), such as a telecommunications network. The core network node(107; 207) obtains the wireless device associated information, encrypts it into an encrypted representation and sends data comprising the encrypted representation to an OAM system (108; 208) via a RAN (101; 201). The first network node (109; 209) receives (306; 71), from the OAM system (108; 208), the encrypted representation of the wireless device associated information, and decrypts it using one or more decryption keys accessible by the first network node (109; 209). |
