One of Zhu’s disclosed inventions concerns a VoIP client and a call implementation method for that client, along with a user terminal. The system connects the client to the Internet through a preset high-speed wireless network and sends a call request to a call controller.

The client selects a number based on the available options and proceeds with the call.

Another invention describes a method and system for implementing a multimedia call. After receiving a request from a VoIP client, a calling controller forwards it to an application server, which obtains rate options for the called party’s registered or associated numbers.
