Abstract: PURPOSE: A method for guaranteeing conformity of connection information among distributed control processors in a control station of a mobile communication system is provided to solve a non-conformity of connection information caused due to an error by driving a restoration algorithm. CONSTITUTION: When an SCP(Switch Control Processor) board of a switch controller(221) is instantaneously failed, the switching controller(221) informs an access routing unit(214) of an SCP restart processing starting(411). The access routing unit(214) sets the SCP to an unavailable state and when a connection request message is received from an access controller, the access routing unit(214) rejects it(412). The access routing unit(214) informs the switch controller(221) of receiving an SCP restart processing start message(413). The switch controller(221) requests pre-set connection information from an AIM(ATM Interface Modules) of every ATM interface unit(222)(414). The ATM interface unit(222) extracts pre-set connection information in each AIM on the basis of uni-directional connection(415) and gives the switch controller(221) the pre-set connection information in each AIM(416). The switch controller(221) restores connection information of itself by using the information received from the AIMs of every ATM interface unit(222) and judges whether connection information in the SCP has been completely generated(417). The switch controller(221) is restored to a previous state before restarting and informs the access routing unit(214) of the SCP restart processing completion(418). The access routing unit(214) sets the SCP state to an available state to normally process a connection request message as received(419). The access routing unit(214) informs the switch controller(221) of receipt of the SCP restart processing completion message(420).

Abstract: PURPOSE: A method for transiting antenna beams between sectors in a smart antenna base station system, a recording medium storing a program to realize the same, and an IMT-2000 system using the same are provided to maintain the balance of traffic loads between sectors and reduce unnecessary handoffs by transferring antenna beams between sectors according to a change in radio environments. CONSTITUTION: If a BCP(Base station transceiver Control Processor) requests a channel card to start the sector transition of antenna beams, the channel card responds to the request(S301,S302). If the BCP requests the channel card to adjust the time and power of a primary-CPICH(Common Pilot CHannel) by stages(S303), the channel card issues an internal operation order so as to adjust the power of antenna beams(S304) and induces antenna beams to be transferred between sectors(S305). Afterwards, if the transition of antenna beams to an adjacent sector is completed, the BCP requests the channel card to execute a completion procedure for the sector transition of antenna beams(S306). As the channel card responds for the completed transition, the sector transition of antenna beams is completed(S307).

Abstract: PURPOSE: A mobility management method in a cellular mobile communication system is provided to reduce unnecessary handover procedures and handover failure number by controlling a handover priority. CONSTITUTION: A second base station measures the dwell time of a terminal which hands data over from a first base station to a second base station(S310). In case the dwell time is lower than a predetermined threshold value, the second base station transmits messages including the dwell time to a first base station(S320). The first base station accumulatively manages one or more information. A handover candidate priority for the first and the second base station is changed based on the accumulated information(S330).
