Abstract: Combinational networks provide simultaneous connectivity via networks of different network type between user equipment. For communication sessions on different network types, belonging to the same user equipment, a correlation check is enabled by introduction of an identifier denoted as Combinational Call Indicator (CCI). This CCI identifier in combination with the known Calling Line Identity (CLI) identifier enables user equipment and other and network entities to perform a correlation check between ongoing, or to be established, CScalls and PS-sessions. A user equipment, setting up a related communication session, sets the CCI identifier and provides the CCI identifier during the communication session setup towards the receiving user equipment or network entity, which is enabled to check whether the last received communication session is correlated to the earlier established session due to the presence of the CCI identifier.

Abstract: A method of managing location information of an Unlicensed Mobile Access terminal in a Global System for Mobile Communications network. An IP address of the terminal is received at a Generic Access Network Controller. The Generic Access Network Controller then sends a query to a Connectivity Session Location and Repository Function associated with the IP network or IP sub network through which the UMA terminal has gained IP connectivity for the purpose of attaching to a Mobile Switching Center or Serving General Packet Radio System Service Node. The Connectivity Session Location and Repository Function sends location information to the Generic Access Network Controller, which then transmits the location information to a Mobile Switching Center or a Serving General Packet Radio System Service Node.

Abstract: A technique for controlling an access domain selection is described. The technique is applicable to user terminals that are capable of switching from a first network access domain to a second network access domain while services are provided to the user terminals. According to a network aspect of this technique, a network node receives a request message from a user terminal. In response to this request message, the network node sends a rule set including one or more access domain switching rules to the user terminal. These access domain switching rules may be dynamically selected by the network node to control the access domain switching behavior of the user terminal.

Abstract: The present invention relates to an overlay system between a GSM and IMS network, making use of virtual IMS subscriptions, which are temporary coupled with the identity of a non SIP compliant terminal, when the non SIP compliant terminal makes a call, is called or invokes an IMS service during the call, for the purpose of initiating a SIP session providing an IMS service to the terminal.

Abstract: Rerouting, as specified by ITU-T Q.730 is a network service that is executed by and under control of switching nodes, whereas IN services are executed under the control of a service control entity and invoked for certain calls only. Because of the two levels of control that are also separate from each other, inconsistencies may occur when an IN service is invoked for a call that may be in addition subject to rerouting. This problem is solved-in that a service control entity is adapted to perform the steps of receiving information relating to the rerouting of the call from the service switching entity, selecting a rerouting procedure for the call according to the received information, and sending an instruction to the service switching entity to continue the call according to the rerouting procedure. The information relating to the rerouting of the call information is in particular information about a rerouting capability of a preceding switching node.

Abstract: A technique for performing a service domain selection in a communications network having a default service domain and at least one alternative service domain is described. According to this technique, a switching to the alternative service domain involves the invocation of a supplementary service that is provided as a supplement to a basic service. A method implementation of this technique comprises steps of identifying a basic service type associated with a service request; determining if for at least one of an originating side and a terminating side of the service request the identified basic service type is linked with a subscription to the supplementary service of service domain switching; and invocating the supplementary service of service domain switching if a linking can be determined.
