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.

An anti-counterfeiting system and method for an e-ticket are disclosed. The anti-counterfeiting system includes a ticket service center, a handheld device, a ticket checking device, and a database. The ticket checking device identifies the e-ticket information shown on a display of the handheld device at least twice. The e-ticket is verified by using the handheld device to execute a ticket software including an e-ticket service. The handheld device obtains at least one e-ticket information from the ticket service center via a network link. When the display of the handheld device shows that the e-ticket information is read by the ticket checking device and is verified by the database, the ticket service center transmits an e-ticket verification information to the handheld device, and the display of the handheld device then shows the e-ticket information for the ticket checking device to check again.

A method for segmenting video and audio into clips using speaker recognition is provided to segment audio according to speaker audio, and to make audio clips correspond to the audio and video signals to generate audio and video clips. The method instantly trains an independent speaker model by increasing an unknown speaker source audio signal, and the speaker recognition result is applied to determine the audio and video clips. Independent speaker clips of source audio are determined according to the speaker model and the speaker model is renewed according the independent speaker clips of source audio. This method segments audio by the speaker model without waiting for complete speaker feature audio signals to be collected. The method is also able to segment the audio and video into clips based on the recognition result of speaker audio, and can be used to segment TV audio and video into clips.
