  • Patent number: 10033549
    Abstract: An inter-network connection control device that is used for interconnecting a communication network and another communication network includes a request signal forwarding unit that forwards a connection request signal transmitted from originating user equipment in the communication network to the other communication network, and a response signal processor that receives, from the other communication network, a plurality of response signals with respect to the connection request signal, the plurality of response signals being forked in the other communication network receiving the connection request signal and being forwarded to a plurality of terminating user devices, and that forwards one response signal of the plurality of response signals to the originating user equipment.

  • Publication number: 20150215756
    Abstract: A UE transmits an INVITE message (call origination request) for an emergency call to an E-CSCF. The E-CSCF receives the INVITE message through an eNB and determines a PSAP of a connection target of the emergency call based on the received INVITE message. When there are multiple emergency call categories (for example, Fire and Ambulance) associated with an emergency telephone number allocated to the PSAP, the UE transmits the INVITE message including P-Emergency-Sub-Category indicating the multiple emergency call categories to the E-CSCF. The call control unit determines the PSAP based on the multiple emergency call categories included in the received INVITE message.
