The invention relates to a method for enabling a content provider initiated delivery of a content clip to a mobile terminal 4 via a communication network, which communication network comprises different types of radio access networks 1,2, and which content clip is required to be delivered via a specific type of radio access network. In order to enable such a delivery, it is proposed that in case it is determined that the mobile terminal 4 does not access the communication network via a radio access network 2 of the type required for the delivery of the content clip, a handover of the mobile terminal 4 to a radio access network 2 of the required type is triggered. The content clip can then be delivered to the mobile terminal 4. The invention relates equally to a corresponding system, to a corresponding communication network and to elements performing the proposed steps.
