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 method for performing an intra-PDSN(Packet Data Serving Node) high-speed soft hand-off through a communication between BSCs(Base Station Controllers) is provided to replace a hard hand-off from an S(Source)-BSC to a T(Target)-BSC with a soft hand-off, perform the soft hand-off, maintain the S-BSC as an anchor, and offer a packet data service in an active mode. CONSTITUTION: An S-BSC(103) transmits an idle forward frame to a T-BSC(107)(S207). The T-BSC(107) transmits the idle forward frame as soon as the T-BSC(107) acquires a synchronization, and prepares for transmitting an idle reverse frame(S209). The T-BSC(107) transmits the idle reverse frame to the S-BSC(103) as soon as the T-BSC(107) receives the idle forward frame from the S-BSC(103)(S211). The T-BSC(107) transmits an A7 hand-off request acknowledgement message to the S-BSC(103) for informing that the addition of the cell is successfully achieved(S213). If the S-BSC(103) acquires the synchronization of the T-BSC(107) and an A3 traffic sub-channel, the T-BSC(107) transmits an A3 traffic channel status message(S215). If the S-BSC(103) transmits a hand-off direction message to an MS(101) and adds a new cell in an active set(S217), the MS(101) transmits an MS acknowledgement message for answering to the hand-off direction message and transmits a hand-off completion message for informing the successful result of the hand-off direction message process(S221). The S-BSC(103) transmits a BS(Base Station) acknowledgement order to the MS(101)(S223), and transmits a hand-off performed message to an MSC(Mobile Switching Center)(111).

Abstract: PURPOSE: A method for performing an inter-PDSN(Packet Data Serving Node) high-speed hard hand-off through a link setup between BSCs(Base Station Controllers) through an MSC(Mobile Switching Center) is provided to perform a communication through the link setup between the BSCs through the MSC in an active packet session mode in an IMT-2000(International Mobile Telecommunications-2000) wireless packet mobile communication network and offer a packet data service in a high speed without losing data. CONSTITUTION: An MSC(111) selects a T(Target)-BSC(107) having an available wireless channel from a cell list, inserts a PANID(Previous Access Network ID) and a hard hand-off indicator into a hand-off request message, and transmits the hand-off request message to the T-BSC(107)(S203). The T-BSC(107) receives the hand-off request message, assigns a suitable idle wireless resource, and sets an ATM(Asynchronous Transfer Mode)-based link channel between an S(Source)-BSC(103) and the T-BSC(107) through the MSC(111)(S205). The T-BSC(107) transmits a hand-off request acknowledgement message including wireless channel information to the MS(111) so that an MS(101) performs a tuning to the corresponding wireless channel and starts a T9 timer to wait for receiving a signal transmitted from the MS(101)(S207). The MSC(111) receives the hand-off request acknowledgement message, prepares the switching of a call from the S-BSC(105) to the T-BSC(107), and transmits a hand-off command including wireless channel information received from the T-BSC(107) to the S-BSC(103)(S209). The S-BSC(103) transmits a GHDM(General Hand-off Direction Message) or a UHDM(Universal Hand-off Direction Message) to the MS(101), and starts a Twaitho timer for admitting that the MS(101) is returned to the S-BSC(103)(S211). The MS(101) transmits an MS acknowledgement order message to the S-BSC(103)(S213). The S-BSC(103) transmits a hand-off commenced message to the MSC(111) for informing that the MS(101) is instructed to be moved to a channel of the T-BSC(107)(S215). If the MS(101) acquires synchronization using a reverse traffic channel frame or preamble data and completes a hard hand-off procedure, the MS(101) transmits a hand-off completion message to the T-BSC(107)(S217). The T-BSC(107) receives the hand-off completion message and transmits a BSC acknowledgement order message to the MS(S219).
