摘要：Devices configured to initiate a handover of a communication session of a user device from an access network associated with unlicensed spectrum to a circuit-switched access network are described herein. The devices may provide a handover request to a server associated with the circuit-switched network, receive a response from the server indicating that the circuit-switched access network has been prepared for the handover, and instruct the user device connect to the circuit-switched access network to continue the communication session. The devices may initiate the handover responsive to measurement reports received from the user device. In some embodiments, the devices may also enable registration of the communication session, determine a session transfer number identifying a component of the telecommunication network which maintains continuity for the communication session, and provide that session transfer number to the server associated with the circuit-switched access network as part of the handover request.
