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: A transmission system for relaying short messages comprising a sender of short messages and a receiver of short messages. The short message sender comprises sending means for sending a deleting short message including at least the address of the receiver and the identifier of a short message to be deleted. The short message receiver comprises identification means for identifying the deleting short message and deletion means for deleting the short message according to the identifier of the short message to be deleted in the deleting short message from the memory intended for the short messages of the receiver.

Abstract: The basic idea of the invention is to separate the location area used in the RAN and the reporting area used when reporting the location of the mobile to the core network. The size of the location area is selected preferably in the RAN based on the services used by the subscriber to optimize the use of radio resources. A reporting area comprises one or a plurality of location areas. The size of a reporting area is selected based on the accuracy of location information needed in the core network. The RAN informs the core network when a subscriber moves out of his current location area. The core network and the radio access network negotiate the size of the reporting area prior to the activation of the service. Additionally, the reporting areas can be renegotiated when the service is in the active state.

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: A cellular radio access network and a location updating in a cordless communications system, in a cellular radio access network (1), which is connected to one or more core networks (2, 3, 4, 5) or services (SP2 to SP5), each of them having a dedicated mobility management. In a cell, identities of all those location areas are broadcast to which said cell belongs. A subscriber terminal (MS) sends to the radio access network only one location updating message irrespective of how many core networks (2, 3, 4, 5) or services (SP2 to SP5) have a simultaneously changing location area at a handover from one cell to another. On the basis of the information contained in the location updating message, the network (1) defines the core networks or services and location areas to which the location updating applies and sends a location updating message informing the new location of the subscriber or the subscriber terminal separately to each defined core network or service.

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.
