  • Publication number: 20220255936
    Abstract: A method performed by a PGW for handling a UEs access to an EPC service via a non-3GPP access network. During a request for connecting the UE to the non-3GPP access network, the PGW receives identity information which indicates an identity of an AAA node from a non-3GPP access gateway. The PGW selects the AAA node which was indicated in the received identity information. The PGW transmits, to the selected AAA node, a request message for the UE. The request message is a request for authorization of the UE to access the EPC service via the non-3GPP access network.

  • Patent number: 9900805
    Abstract: A technique is provided for synchronizing a first call state of a network component and a second call state of a mobile device. The mobile device is connectable to a network via a first Radio Access Technology (RAT) and a second RAT. The network forwards towards a callee an invitation for a call originating via the first RAT from the mobile device. The network sends a first message corresponding to a callee response towards the mobile device. The network component triggers a transfer of the call session of the mobile device from the first RAT to the second RAT. The first call state is set by the response of the callee. Information indicative of the second call state is received from the mobile device, and a second message for changing the second call state by the response is provided to the mobile device when inconsistent first and second call states.

  • Patent number: 9706449
    Abstract: A technique for triggering a change of a call state of a mobile device is presented. A network forwards towards a callee an invitation for a call originating via a first Radio Access Technology (RAT) from the mobile device, and forwards a response of the callee via the first RAT towards the mobile device. The response indicates a change of the call state from a first state to a second state. A first network component changes via a second RAT the call state of the mobile device when receiving information indicative of the first state followed by receiving a message indicative of the second state. A second network component receives from the first network component an invitation for a transfer of the call of mobile device from the first RAT to the second RAT.

  • Patent number: 9510178
    Abstract: A method for a fallback core network node within core network nodes for a first mobile terminated call towards a mobile subscriber initially assigned to a failing ore network node (failing CNN). The method includes receiving data associated to International Mobile Subscriber Identity and Location Area Identifier (LAI) of a mobile subscriber handled in the failing CNN. The method includes receiving a service request from a home location register (HLR), whereby the service request indicates that the fallback CNN is acting as a fallback CNN for the failing CNN, and sending a response to the service request towards the HLR comprising the roaming Number assigned by the fallback CNN. The method includes initiating a paging request towards the radio network comprising said received LAI of said mobile subscriber, and sending a Service Request towards the HLR comprising the Mobile Station Integrated Services Digital Network Number of the mobile subscriber.
