  • Publication number: 20160127425
    Abstract: The present invention provides a registration method for managing NAT shutdown. In Internet communication field, a user must perform registrations intermittently to a server through NAT, and increase the time interval of registration step by step. But NAT itself will shutdown if no packet is passed through for a long period. The registration method of the present invention is to adjust the time interval of registration step by step so that the time interval of registration is slightly less than the shutdown time of NAT, and then fix the time interval of registration to assure that all of the Invite packet can pass through without blocking up by the shutdown of NAT.

  • Publication number: 20160043895
    Abstract: The present invention provides a toning control method for setting a WiFi device by a smart device so that the WiFi device can link with Internet through a WiFi AP. The present invention is different from the prior art that a smart phone uses WiFi signal to set an IP camera, and is also different from the prior art that a smart phone generates QR Code for setting an IP camera. The present invention adopts methods of DTMF (Dual-Tone Multi-Frequency) or FSK (Frequency-Shift Keying) for toning encoding, and sends the toning encoding through a loudspeaker of the smart device to a toning decoder of the WiFi device for toning decoding, then performs the setting and linking of the WiFi device.

  • Publication number: 20150350899
    Abstract: The present invention provides VoIP authentication in 4G VoLTE, and also provides an extra authentication method of VoLTE for achieving communication security. The key point of the extra authentication method of VoLTE is: when a 4G mobile phone is turned on for the first time, a security registration sequence number will be random generated by the 4G mobile phone, and sent with IMSI and IMEI through TLS to an account assignment server for comparison and storage. Thereafter the account assignment server sends an account and a password in a database corresponding to IMSI to the 4G mobile phone, and then the 4G mobile phone conducts VoIP authentication with a SIP server for standby or communication.

  • Publication number: 20150346824
    Abstract: A user may provide input to a handheld electronic device by making gestures with the handheld electronic device. The input gestures may be used to generate remote control signals for external equipment. The electronic device may include circuitry for detecting a user's movement of the handheld electronic device. The circuitry may include an accelerometer operable in normal and low power modes and a processor operable in sleep and wake modes. Motion data gathered in low power mode may be stored in a dedicated low power mode data storage structure. Motion analysis circuitry may detect a user's movement of the electronic device based on a standard deviation of the motion data. Upon detecting a user's movement of the handheld electronic device, the processor may be woken up to analyze the motion data stored in the low power mode data storage structure and to confirm the user's movement of the electronic device.

  • Publication number: 20140286331
    Abstract: In SIP network environment, a general traversal method for a port restricted NAT will become invalid when other users break in. The present invention provides four sessions for SIP, i.e. Login Session, Port Prediction Session, Multi-Traversal Session and Media Session, and the SIP network environment includes a first Internet telephone, a second Internet telephone, a symmetric NAT, a port-restricted NAT and an SIP proxy server. In the Multi-Traversal Session, the second Internet telephone sends a plurality of identical speech packets to consecutive ports of the symmetric NAT through a fixed port of the port-restricted NAT so as to achieve the NAT traversal.

  • Patent number: 8676933
    Abstract: The present invention provides an NAT (Network Address Translator) traversal method in Session Initiation Protocol (SIP) for solving the problems of SIP in Internet phone (VoIP) under current Internet environment. In other words, the present invention solves the SIP problems caused by NAT (Network Address Translator) that P2P (Peer to Peer) transmission cannot traverse the NAT firewall directly. The major content of the present invention is that the computer conducts multiple registrations before issuing an Invite message in order to detect the rule of the NAT server to assign port number and IP address. Additional commands or parameters beyond the SIP standard are not required for the NAT traversal function. Hence, the capability of SIP for a NAT traversal function is provided without no additional commands or parameters.
