  • Patent number: 9042376
    Abstract: In SIP network environment, a general NAT traversal method will become invalid when an NAT with ICMP (Internet Control Message Protocol) is met. The present invention provides four sessions for SIP, i.e. Login Session, Port Prediction Session, Synchronization Session and Media Session, and the SIP network environment includes a first Internet telephone, a second Internet telephone, a first symmetric NAT, a second symmetric NAT and an SIP proxy server. The first symmetric NAT and the second symmetric NAT are ICMP-sensitive. In the Synchronization Session, the first Internet telephone and the second Internet telephone are designed to transmit packets synchronously to avoid port locking.

  • Publication number: 20130286910
    Abstract: The present invention provides a power saving system for smart mobile communication device in Internet communication. The power saving system comprises two smart mobile communication devices with Internet connection capability, an Internet, a server, a gateway and a mobile communication network. The two smart mobile communication devices cut off the Internet connection usually. When a smart mobile communication device performs a call through the Internet to the other smart mobile communication device, the server, the gateway and the mobile communication network are used to inform the other smart mobile communication device for Internet connection. After both sides stop the Internet communication, the two smart mobile communication devices cut off the Internet connection.
