REVERSE TRAFFIC CHANNEL ALLOCATION METHOD FOR VERTICAL HANDOVER IN HETEROGENEOUS NETWORK AND MOBILE TELECOMMUNICATION SYSTEM FOR THE SAME

PURPOSE: A method for allocating reverse traffic channels during a hand over process among heterogeneous networks, and a wireless communication system thereof are provided to improve the acquisition probability of a terminal using time difference information between CDMA and LTE. CONSTITUTION: A method for allocating reverse traffic channels during a hand over process among heterogeneous networks comprises the following steps: transmitting a CDMA 1xRTT origination message to a subminiature base station(21) by a terminal(40) using an LTE tunneling message when a hand-over execution message is received; and transmitting the transmitted message on the subminiature base station to a CDMA macro base station(20) after passing through an MME(60) and 1xCS IWS/MSC using an E-UTRAN RRC tunneling message.
