Filed: 2000-06-21
Abstract: PURPOSE: A handoff method between frequencies of a mobile communication system is provided to improve a radio environment, heighten success rate of handoff and provide a stable and continuous call service to a subscriber of a mobile station by minimizing use of a handoff related message and simultaneously performing a hard handoff and a soft handoff with a frequency having the least load. CONSTITUTION: When a mobile station is moved to a target base station, if a pilot strength of the target base station is larger than a pilot signal detection critical value, a pilot strength measurement message or a pilot strength report message is transmitted to a CCP of a control station(S1). The CCP analyzes the pilot strength measure message or the pilot strength report message, and if it is in a hard handoff occurrence between frequencies, the CCP detects the same frequency as the frequency provided from the target base station from a serving base station and requests a communication channel allocation for the hard handoff from the serving base station(S2). When the serving base station allocates the hand off communication channel between frequencies by the detected frequency and reports the result t the CCP, the CCP transmits an inter-frequency hard handoff instructing message to the mobile station of the serving base station(S3). The mobile station performs the inter-frequency hard handoff in the serving base station, and transmits an inter-frequency hard handoff performing completion message to the CCP through the serving base station(S4). The CCP analyzes the pilot strength measurement message or the pilot strength report message transmitted form the mobile station, and if it is in a soft handoff occurrence condition, the CCP requests a communication channel allocation for soft handoff from the target base station(S5). When the target base station allocates a soft handoff communication channel with the frequency provided from the target base station and reports the allocation result to the CCP, the CCP transmits a soft handoff instructing message to the mobile station through the serving base station(S6).
