摘要： A mobile node (MN), a WiMAX base station (BS), a Wi-Fi access point (AP) and a handover method therefore, for use in a heterogeneous wireless network system, are provided. The heterogeneous wireless network system comprises a gateway. The WiMAX BS and the Wi-Fi AP can interchange messages with each other via the gateway. There is an overlap service area between the WiMAX BS and the Wi-Fi AP. The MN accepts a network service, which is provided by the gateway, via the WiMAX BS. When the MN enters the overlap service area, it may handover to the Wi-Fi AP without interrupting the network service so that the gateway may provide the network service for the MN via the Wi-Fi AP.

摘要： A receiver receiving a Radio Frequency (RF) signal and generating a baseband signal is provided. An RF module receives the RF signal and down convert the RF signal according to a first oscillation frequency to generate an Intermediate Frequency (IF) signal. An IF module is coupled to the RF module and arranged to receive the IF signal and down convert the IF signal according to a second oscillation frequency to generate the baseband signal. A calibration module is coupled to the RF module and arranged to calculate the IF signal according to a third oscillation frequency to detect an I/Q mismatch, and generate an adjustment signal, accordingly, to calibrate the I/O mismatch.
摘要翻译：提供接收射频（RF）信号并产生基带信号的接收机。 RF模块接收RF信号并根据第一振荡频率对RF信号进行下变频以产生中频（IF）信号。 IF模块耦合到RF模块并被布置成接收IF信号，并根据第二振荡频率对IF信号进行下变频以产生基带信号。校准模块耦合到RF模块并被布置成根据第三振荡频率计算IF信号以检测I / Q失配，并且相应地生成调整信号以校准I / O失配。

摘要： A mobile station, an access point, a gateway apparatus, a base station, and a handshake method thereof for use in a wireless network framework are provided. The wireless network framework comprises a first wireless network comprising the access point, and a second wireless network comprising the gateway apparatus and base station. There is an IP security tunnel between the access point and the gateway apparatus. When the mobile station handovers from the first wireless network to the second wireless network, it transmits a master session key to the gateway apparatus via the access point and the IP security tunnel. Additionally, when the mobile station handovers from the second wireless network to the first wireless network, it transmits a master session key to the access point. As a result, the authentication time, which is needed in handover procedure between the first wireless network and the second wireless network, is reduced effectively.
