Abstract: A system, apparatus and method for establishing circuit-switched (CS) communications in packet-switched (PS) multimedia networks such as IMS, and providing services via the PS networks to CS domain users. A dialog is established between terminals through the PS multimedia network. A service is provided to at least one of the terminals by way of the dialog. CS bearer information, including an indication that a communication flow is requested via a CS network, is communicated between the terminals by way of the dialog. A communication flow via the CS network is effected between the terminals as directed by the CS bearer information. IMS or other PS multimedia network services can thus be provided to users otherwise communicating via the CS-domain.

Abstract: A mechanism for providing a connection from an IP-based network to a circuit-switched network, such as a GSM network is disclosed. A temporary routing number for the circuit-switched network, such as an E.164 number, is delivered to a user terminal, and a circuit-switched call leg is established from the user terminal to the IP-based network using the routing number. Thereby, IMS-services are provided for end users which are located in the radio access network not having sufficient QoS required for voice over IP. In the example of a conference call service, a request for a conference call may forwarded via a data channel or data path to an application server which provides that conference call service. The application server then selects a conference routing number and returns the routing number to the conference host terminal via the data channel. Using the received conference routing number, the conference host terminal can then set up a circuit-switched connection as a call leg of the conference call.

Abstract: A method, system and gateway device enables interworking between an IP-based network and a circuit-switched network. A first address information of a first connection end located in the circuit-switched network is routed in a trigger message from the IP-based network to a gateway control function. The first and second call legs are established in parallel towards the first connection end based on the first address information, and towards a second connection end located in the IP-based network based on a second address information obtained from the trigger message. A single connection between the two connection ends is then established by connecting the first and second call legs. Thereby, IP-based signaling functionality can be used to add capability for subscribers located in the CS domain to be invited into conferences or calls with subscribers located in an IP-based domain, e.g. the IMS domain.

The invention also proposes a corresponding network control method. According to the invention, a flexible service architecture is possible.

Abstract: The present invention relates to a method and system for providing a service in a communication network. A service script is used to control a service execution functional unit to execute the service, wherein an execution priority is allocated to the service script based on the kind of service. Furthermore, a service logic of the service may be provided at a service execution functional unit, and the service script may comprise a service description of the service. The service execution functional unit is then controlled based on the service description to execute the service by using the service logic. Thus, the service script does not contain the service logic, and a flexible service script concept can be provided. Moreover, the signaling traffic can be reduced since the operator does not have to update service scripts for a large amount of subscribers.
