PURPOSE: A hand-off method between control processor in a digital telecommunication system stores BCP(BTS control processor) address of CCP(call control processor) inside of another control processor through a CCP of serving side, performs a hand-off of CCP inside of the control processor, and reduces a hand-off processing time. CONSTITUTION: The hand-off method requires (S2)a blank link ID usable as CCP of another control processor in a CCP state block of a serving side, acquires the blank link according to the request of the first step. The hand-off method gets (S3) BCP address of a corresponding BTS positioned in CCP of another control processor through the blank link ID obtained from the second step, stores (S3) the BCP address as PLD format. After starting a call process (S4), and reads a stored PLD data. The method requires (S8) a traffic channel allocation to BCP of CCP within a control processor, and then performs (S8) a hand-off, thereby reducing a hand-off processing time.
