Abstract: 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.

Abstract: The invention relates to a method for performing an intersystem handover of a mobile terminal accessing a communication network via a radio access network of a first type. The communication network comprises at least this radio access network of this first type and a radio access network of a second type. In order to enable an access to the communication network with a radio access technology required or desired by the mobile terminal, the intersystem handover is initiated by a transmission of the mobile terminal to the communication network, which transmission comprises information indicating that an intersystem handover from the radio access network of the first type to the radio access network of said second type should be performed. The invention equally relates to a corresponding mobile terminal, to a corresponding communication network, to a corresponding communication system, to a network element of a communication network and to a web switch of a communication system.

Abstract: In a telecommunications network having some high mobility subscribers, for which no most likely access point can be determined and the subscriber numbers of which do not include immediate information of the actual location of a subscriber, there are also some semi-fixed subscribers and/or fixed subscribers, for which it is possible to determine their most likely access point and the subscriber numbers of which indicate their most likely access point. In case of incoming calls, the first exchange to process a call in the telecommunications network routes the call on the basis of the called subscriber's subscriber number directly to an exchange serving the subscriber's most likely access point.
