Method and system for providing information of related communication sessions in hybrid telecommunication networks
First Claim
1. A method for providing a verification of whether a call via a Circuit Switched (CS) network and a related Packet Switched session via a Packet Switched (PS) network are combinational, within a telecommunications system comprising said PS and CS networks, where the PS and CS networks are connecting at least a first user equipment and a network entity, where each of the first user equipment and the network entity has a respective connection associated with a respective PS network address in the PS network and a respective connection associated with a respective CS network address in the CS network, the method comprising the steps of:
- establishing a presence of the call in the Circuit Switched network and the related PS session in the Packet Switched network, between the first user equipment and the network entity, the call and the related PS session being present simultaneously,in response to the presence of the call and the related PS session being established, performing a real-time combinational check verifying that the call and the related PS session originate at the first user equipment and terminate at the network entity;
providing at least one subsystem with the verification of the performed real-time combinational check.

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.

23. A network node in a telecommunication system, the network node being configured for providing a verification of whether a call via a Circuit Switched (CS) network and a related Packet Switched (PS) session via a Packet Switched network are combinational, wherein the telecommunication system comprises at least said CS and PS networks, the CS and PS networks being connected to at least a first user equipment and a network entity, where each of the first user equipment and the network entity has a respective connection associated with a respective PS network address in the PS network and a respective connection associated with a respective CS network address in the CS network, wherein the network node comprises:
-
an Input Output (I/O) unit communicatively connected to the at least CS and PS networks, by means of network connections, each network connection having a network address, a processing unit with an application program and a parameter memory for querying network elements having database capabilities or a mediator unit representing said network elements, where the I/O unit in cooperation with the processing unit is configured for establishing the presence of the call and the related PS session simultaneously at each of the at least CS and PS networks, between the first user equipment and the network entity, the network node being configured for performing, in response to the presence of the call and the related PS session being established, a real-time combinational check to verify that the call and the related PS session originate at the first user equipment and terminate at the network entity, and the network node being further configured for providing a verification of the performed real-time combinational check to at least one subsystem. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
