Patent number: 9755793Abstract: A heterogeneous network integrating device and method thereof are provided. The device and method are applied in a communication environment overlapped by a mobile network covering range and a wireless network covering range and using the mobile network and wireless network to transmit downlink traffic. The heterogeneous network terminal enables the mobile network air interface and wireless network air interface at the same time when transmitting the downlink traffic and requests the mobile network end to transmit by the mobile network and wireless network at the same time. The mobile network end assigns the downlink traffic of the heterogeneous network integration terminal to the mobile network and the wireless network. This uses the bandwidth feature of mobile network and wireless network to promote transmission rate of downlink traffic and shorten user waiting time.Type: GrantFiled: September 19, 2016Date of Patent: September 5, 2017Assignee: CHUNGWA TELECOM CO., LTD.Inventors: Chung-Ho Wang, Chia-Horng Liu, Sz-Hsien Wu

Patent number: 8086180Abstract: A method for restraining inter-cell interference in a mobile communication system is provided. The method uses the fast dynamic selection of the Fractional Frequency Reuse (FFR) technology and the Macro Diversity (MD) technology of the cell edge to increase the cell edge user data rate and provide excellent system capacity. The method is particularly suitable in a OFDMA mobile communication system downlink. The method comprises the steps of: (a) determining whether the cell edge user is able to operate the MD technology; (b) processing the fast dynamic selection of the FFR technology and the MD technology for the cell edge user, and the selection is made based on a instantaneous link Signal Quality Index (SQI); and (c) allocating the center subband or the edge subband to the cell edge user according to the selection.Type: GrantFiled: April 21, 2009Date of Patent: December 27, 2011Assignee: Chunghwa Telecom Co., Ltd.Inventors: Che-Sheng Chiu, Chih--Hsuan Tang, Chia-Horng Liu

Patent number: 6937978Abstract: A suppression system of background noise of speech signals uses an adaptive filter of long-time and short-time statistical characteristics of the speech signals. Since the statistical characteristics of the speech signals vary with time, the associated coefficents of the filter also have to be adjusted according to the varitation of the speech signals to eliminate the unnecessary background noise. High frequency attenuation of the speech signals is compensated for by passing the signal through a high frequency booster to elevate the degree of brightness of the speech signals and to improve their quality.Type: GrantFiled: October 30, 2001Date of Patent: August 30, 2005Assignee: Chungwa Telecom Co., Ltd.Inventor: Chia-Horng Liu
