ABSTRACT:
Disclosed herein is a portable Internet analyzer (PIA) having a handover test function. The portable Internet analyzer includes a transmission unit, a reception unit, a switching unit, and a central control unit. The transmission unit encodes the various DownLink signals of a serving and/or target Base Station (stBS) using a preamble index, synthesizes the encoded signals, and sends the synthesized signals to a Portable Subscriber Station (PSS). The reception unit receives various UpLink (UL) signals from the PSS, and decodes the UL signals using the cell Parameters of the stBS. The switching unit selectively switches the transmission unit and the reception unit to the PSS. The central control unit generates various Media Access Control (MAC) messages to be sent to the PSS through the transmission unit in association with the handover test, analyzes handover test-related MAC messages received through the reception unit, and controls switching operation of the switching unit.
