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 mobile communication service method using the EVDO dedicated frequency layer from the building portion and the device. Mobile communication service apparatus using an EVDO only frequency in building some of the layers in accordance with a preferred embodiment of the invention is a commercial frequency conversion to transmit a signal of the dedicated frequency corresponding thereto receives a signal of a commercial frequency in the direction out to the outside of the building device, corresponding only frequency conversion apparatus for transmitting a signal of the power frequency to respond to receiving a signal of the dedicated frequency, is provided only to PN Pollution heavy upper in the building, to receive the EVDO only frequency as the input signal thereto which comprises the EVDO frequency conversion device for transmitting signals of the EVDO commercial frequency, the terminal receives the signal of a commercial frequency from said dedicated frequency conversion device with EVDO frequency inverter transitions to the dedicated frequency to the commercial frequency converter to receive the signal from the frequency-only can transition to the power frequency. According to the present invention, PN Pollution can be provided a high-quality mobile communication service by using a separate dedicated frequency PN Pollution is not generated without relatively interference to EVDO call in some of the layers of heavy construction. ; Only frequency, the commercial frequency, the frequency conversion device EVDO, PRL.
