A threat detection system for a mobile communication system, and a global device and a local device thereof are provided. The threat detection system is used for detecting and defensing low and slow distributed denial-of-service (LSDDoS) attacks. The global device is located in a core network of the mobile communication system, and is used for training a tensor neural network (TNN) model to build a threat classifier. The threat classifier is used for the local device to identify a plurality of threat types. The local device inputs the to-be-identified data into the threat classifier to generate a classification result corresponding to one of the threat types.

A frequency calibration apparatus and method are provided. An oscillator of the frequency calibration apparatus has an operation frequency. The frequency calibration apparatus receives a plurality of time packets from an NTP server at a plurality of first time points. Each of the time packets records a second time point that the NTP server transmits the time packet. The frequency calibration apparatus calculates an offset for each of the time packets in a subset of all the time packets, calculates a clock skew according to the first time points and the offsets of the time packets in the subset, calculates a difference between the clock skew and a standard frequency value, determines that an absolute value of the difference is greater than a threshold, and adjusts the operation frequency to an initial frequency after determining that the absolute value of the difference is greater than the threshold.

Frequency calibration apparatus and method

A satellite positioning method, a satellite pseudorange calculation apparatus and a satellite pseudorange calculation method thereof are provided. The satellite pseudorange calculation apparatus is used for calculating a pseudorange between a satellite and a satellite positioning receiving device, wherein the pseudorange includes an integer code value and a fractional code value. The satellite pseudorange calculation apparatus comprises a receiver and a processor electrically connected with the receiver. The receiver is configured to receive a code phase from a satellite signal acquisition unit, and the processor is configured to calculate the fractional code value according to the code phase. The receiver is further configured to define an approximation position and calculate the integer code value according to the approximate position and the fractional code value. The satellite positioning method is used for positioning the satellite positioning receiving device.

A disaster monitoring and pre-warning system comprises a disaster informing system, peer-to-peer wireless communication devices, a monitoring host and a pre-warning message issuing host. The disaster informing system transfers at least one first disaster information. The peer-to-peer wireless communication devices sense at least one disaster event to generate at least one second disaster information. The at least one second disaster information is transferred by a peer-to-peer technology. The monitoring host receives the at least one first disaster information and the at least one second disaster information to generate a first pre-warning information. The pre-warning message issuing host issues the first pre-warning information.

Disaster monitoring and pre-warning system and method thereof

A positioning device and a positioning method thereof are provided. The positioning device can cooperate with a first satellite group and a second satellite group, and it comprises a storage, a receiver and a processor. The receiver is configured to receive a first satellite group signal from the first satellite group and a second satellite group signal from the second satellite group. The processor is electrically connected to the storage and the receiver, and configured to calculate a positioning offset value according to one of the first satellite group signal and the second satellite group signal. In addition, the processor is configured to calculate a positioning result according to the second satellite group signal and the positioning offset, and store the positioning result in the storage.

Positioning device and positioning method thereof

The present invention provides a system, method and article of manufacture for personal catalog and knowledge management.
