Latest Patents

Fu’s listed patents concern methods for carrying telephony signaling through voice-over-packet and IP networks.

“Arrangement for Providing ISUP Transparency Across Voice over Packet Networks Based on Determined Exchange Type” describes a voice-over-packet network in which ingress and egress gateways share information to select an exchange type for transporting signaling messages. The gateways interface with their respective telephony switches using the switches’ signaling protocols, supporting transparent message transport between the source and destination.

“Arrangement for Protocol Independent Transfer of Control Parameters Across Internetworks Using Generic Transparency Descriptor Objects” describes a network node that converts signaling information into an IP-based transport message. A generic transparency descriptor identifies the source protocol and message type, and may include message-specific parameters. Receiving nodes can use this information to determine whether they can perform the requested signaling operations or use alternatives.

Career Highlights

Fu’s patent portfolio reflects work on interoperability between traditional telephony systems and packet-based networks. The inventions emphasize conveying protocol and message details so that signaling can be interpreted and handled across network boundaries.

Collaborations

Fu’s listed coworkers include Thang Tat Do and Henry Louis Fourie. His association with Cisco Technology, Inc., places his work within a company active in communications networking.

Conclusion

Taiqi Fu’s patents address practical challenges in transporting and interpreting telephony signaling across packet networks, with a focus on protocol transparency and interoperability.
