Latest Patents
One of Zhengxiong Lei's latest patents is titled "Method for handing over a terminal during a non steady VoIP call, network element, device and system." This invention provides a method for transferring a terminal from a packet switching domain to a circuit switching domain during a non-steady state of a call. It includes a network element managing service centralization and continuity, an access device, and a network element managing the mobility of a terminal. The method involves a first network element anchoring the call based on a setup request from the terminal and storing a provisional response. The terminal detects the need for a handover and sends a measurement report to the access network, which then decides to request a second network element for the handover. This process ensures a seamless transition during a call.
Another notable patent is the "Method for shortening signaling delay of ISC session transfer, network element and system." This invention aims to reduce the signaling delay during the ISC session transfer procedure. It includes a network element for controlling the ISC session transfer and a communication system with at least two terminals. The method allows for the division of the session into two independent sub-sessions, which streamlines the handover process and minimizes disruptions.
