A server, a communication system, and a performance measurement method are provided. In the method, frequency spectrum information is determined. The frequency spectrum information includes multiple frequency spectrums supported by at least two mobile networks. A network configuration is generated according to the frequency spectrum information. The core network entity instructs a radio access network node (i.e., base station) to transmit a control message to a user equipment (UE) according to the network configuration. The frequency spectrums are scanned for a network performance measurement of the UE, and the UE is allowed to register to at least one its own subscribed mobile network of the at least two mobile networks but not allowed to register to the others of the at least two mobile networks. Accordingly, an easier way to motoring competitors' network performance is provided.

Server, communication system, and performance measurement method

A server, a communication system, and a positioning method based on mobile network thereof are provided. In the method, a first measurement report and a second measurement report are received. The first measurement report is related to a first network performance measurement of a user equipment (UE) with a mobile network and includes first location information of the UE, and the second measurement report is related to a second network performance measurement of the UE with the mobile network. The Second location information of the UE is determined according to a monitoring result obtained from the second measurement report. The monitoring result is related to the signal transmission condition of the UE in the mobile network. The second location information is calibrated according to the first location information. Accordingly, the accuracy of the location of the UE may be improved.

Server, communication system, and positioning method based on mobile network thereof

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.

Mobile station, access point, gateway apparatus, base station, and handshake method thereof for use in a wireless network framework

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.

Wireless signal receiving method and receiver for in-phase to quadrature (I/Q) mismatch calibration

An implement method of a FFT processor comprises the following steps. First, a 2point FFT processor, which has an output and an input receiving a 2point data, is provided. A 2-point FFT processor having an input and an output is provided. Sequentially, a multiplexer, which has a first input coupled to the output of the 2point FFT processor, a second input receiving a 2point data and an output coupled to the input of the 2point FFT processor, is provided. When an input data is a 2point data, the second input of multiplexer is coupled to the output thereof, and when an input data is a 2point data, the first input of multiplexer is coupled to the output thereof.
