There is provided a mechanism for triggering offloading in the case that a traffic congestion occurs in a network part. When a traffic congestion state in a communication network part is detected, a congestion indication comprising an information element indicating a request for initializing a traffic offloading procedure to another communication path is sent to a communication network control element. The communication network control element determines, on the basis of a traffic congestion state, whether a traffic offloading in a communication network part is to be initialized, and sends, in case the determination of the offloading determining portion is affirmative, an offloading indication to a host network element in the communication network part, wherein the offloading indication triggers offloading of traffic to another communication path.
