Method for mobile communication service using EVDO dedicated frequency in partial building and Apparatus thereof

摘要

The present invention relates to a mobile communication service method and apparatus, and more particularly to a method mobile communication service using a dedicated frequency EVDO In some story building and apparatus. Mobile communication service system using EVDO only frequency in some storey building according to an embodiment of the present invention is a commercial frequency conversion to the transmission in the direction out of the signal of the dedicated frequency corresponding to receiving signals of the power frequency to the outside of the building device, only frequency conversion device for receiving a signal from the dedicated frequency transmitting signals of the power frequency which corresponds to this, is provided PN Pollution severe upper part only in the construction, corresponding to receive EVDO only frequency as the input signal including but EVDO frequency converter for transmitting the signals of the EVDO commercial frequency, the terminal as a dedicated frequency shifting by receiving the signal of a commercial frequency from EVDO frequency conversion device and the dedicated frequency converter, and the power frequency converter It receives a signal of only the frequency from the power frequency It may transition. In accordance with the present invention, PN Pollution is not the PN Pollution caused by using a separate dedicated frequency for the EVDO call in some of the layers of the heavy construction it is possible to provide a relatively high interference in a mobile communication service is not. ; Only frequency, power frequency, EVDO frequency converter, PRL.
