Patent number: 9781171Abstract: 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.Type: GrantFiled: December 3, 2014Date of Patent: October 3, 2017Assignee: NATIONAL TAIPEI UNIVERSITY OF TECHNOLOGYInventors: Shaw Hwa Hwang, Cheng Yu Yeh, Kuan Lin Chen, Yao Hsing Chung, Chi Jung Huang, Li Te Shen, Shun Chieh Chang, Bing Chih Yao, Chao Ping Chu, Ning Yun Ku, Tzu Hung Lin, Ming Che Yeh

Publication number: 20160323455Abstract: The calculation for DFT(Discrete Fourier Transform) is too much in prior art, so the present invention provides a new method DMFT(Discrete Multi-Frequency Transform) for calculation. For example, in prior art, to determine a DTMF signal “3”, the calculation must be performed for k=96˜92 (frequency 1477 Hz with tolerance ±2.5%) and k=45˜43 (frequency 697 Hz with tolerance ±2.5%), total 8 of X[k] value have to be calculated, but the present invention performs a single calculation of X[k] for each frequency. To determine a DTMF signal “3”, only a high frequency of X[k] and a low frequency of X[k] are required to calculate.Type: ApplicationFiled: April 30, 2015Publication date: November 3, 2016Inventors: Shaw Hwa HWANG, Li Te SHEN, Kuan Lin CHEN, Yao Hsing CHUNG, Chi Jung HUANG, Cheng Yu YEH, Shun Chieh CHANG, Bing Chih YAO, Chao Ping CHU, Ning Yun KU, Tzu Hung LIN, Ming Che YEH

Publication number: 20150350899Abstract: 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.Type: ApplicationFiled: June 18, 2014Publication date: December 3, 2015Inventors: Shaw Hwa HWANG, Cheng Yu YEH, Kuan Lin CHEN, Yao Hsing CHUNG, Chi Jung HUANG, Li Te SHEN, Shun Chieh CHANG, Ming Che YEH, Bing Chih YAO, Chao Ping CHU, Ning Yun KU, Tzu Hung LIN

Publication number: 20140286331Abstract: 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.Type: ApplicationFiled: April 2, 2013Publication date: September 25, 2014Applicant: National Taipei University of TechnologyInventors: Shaw Hwa Hwang, Cheng Yu Yeh, Kuan Lin Chen, Yao Hsing Chung, Chi Jung Huang, Li Te Shen, Shun Chieh Chang, Bing Chih Yao, Chao Ping Chu, Ning Yun Ku, Tzu Hung Lin, Ming Che Yeh

Patent number: 8676933Abstract: 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.Type: GrantFiled: March 12, 2009Date of Patent: March 18, 2014Assignee: National Taipei University of TechnologyInventors: Shaw Hwa Hwang, Kuan Lin Chen, Shun Chieh Chang, Chi Jung Huang, Li Te Shen, Ben Chen Liu
