The disclosure relates to a method of supporting monitoring of an encrypted data communication session of a first device, the method comprising: receiving a signal for initiating a communication session with a second device; generating an encryption key for encryption of the communication session; determining whether a monitoring signal is received for the communication session; and transmitting information about the encryption key to the second device by using a predetermined packet based on the determination.

Method, apparatus, and system for monitoring encrypted communication session

Disclosed is a portable internet system, and more particularly, to a method of supporting fast ranging upon handover. The method comprises calculating an action time based on a time when a handover confirmation message is received from a serving Radio Access Station (RAS), in a target RAS; and transmitting a fast ranging information message to a mobile station on the basis of the action time.

Method for supporting high speed ranging during handover

A radio frequency (RF) receiver and a method of receiving an RF signal are provided. The RF receiver includes a low-noise amplifying unit which amplifies a received signal while restricting out-of-band interference of the received signal, a sampling unit which performs sampling to convert the amplified signal to a discrete time domain signal, a frequency translation unit which down-converts the discrete time domain signal into a frequency band that enables the discrete time domain signal to be converted into a digital signal and restricts interference from a frequency within an aliasing band according to a sampling frequency, an anti-aliasing filtering unit which prevents aliasing from the down-converted signal, a clock unit which provides the sampling unit, the frequency translation unit, and the anti-aliasing filtering unit with sampling frequencies, and an analog-digital-converter which converts the converted signal into the digital signal.

RF receiver and method to receive, amplify, sample, down convert, anti-aliasing filter, and ADC convert an RF signal

A low noise amplifier is provided. The low noise amplifier includes: a low noise amplifying unit amplifying an input signal; a harmonic and noise generating unit disposed in an input terminal of the low noise amplifying unit, for generating a compensating signal for compensating for an intermodulation distortion signal and a thermal noise signal of the input signal to the low noise amplifying unit; and a load unit outputting the amplified input signal generated by the low noise amplifying unit.
