Abstract: A message (203) of a first communication service is received from a service provider. On the basis of the received message (203) of the first communication service, an information element for personalizing communication services is stored. The received message (203) of the first communication service is then forwarded towards a subscriber (10). Further, a message (205) of a second communication service is received from the subscriber. The stored information element is inserted into the received message (205) of the second communication service. The received message (205) of the second communication service with the inserted information element is then forwarded towards the service provider. The service provider may then personalize the second communication service based on the information element.

Abstract: Combinational networks may provide simultaneous connectivity over networks of different network types between user equipment. A communication session, comprising a circuit switched call and one or more packet switched sessions, may be deployed simultaneously over different network types, in relation to the same user equipment. The circuit switched call and the packet switched session can be correlated, in which case the communication session is regarded as a combinational session. By introducing a number of logical databases that contain actual data on network addresses and communication sessions, a correlation check is deployed applied by a correlation node. The check consists of a number of queries towards said databases or to other network entities, yielding whether the communication session is to be regarded as combinational. The result of the check may e.g. be deployed in an on-line combinational charging system.

Abstract: A UE has a subscription to a Home Public Land Mobile Network (H-PLMN) and has a subscription to an Alternative Roaming Provider (ARP) stored in a subscription database. The ARP is adapted to provide a communication service to the subscriber if the subscriber roams into a Visited Public Land Mobile Network (V-PLMN) which is different from the H-PLMN. The method includes registering the UE at a control node of the V-PLMN and sending, by the control node, a request for subscription data to the subscription database. The method further includes: sending, by the subscription database, an indication of the ARP to the control node; generating, by the control node, network identification information, based on the indication of the ARP and the indication of the V-PLMN; and sending, by the control node, the network identification information to the UE.
