Abstract: 본 발명은 이동통신시스템에서 핸드-오버시 데이터 전송에 관한 것으로, 특히 주파수간 핸드-오버(Inter frequency Hand over)와 같은 하드 핸드-오버(Hard Hand Over)에서 기존 링크에서 새로운 링크로 통신경로를 바꾸는 과정에서 기존링크에 있던 전송되지 않은 데이터가 유실을 막고 신뢰성 있는 하드핸드-오버를 지원하기 위한 시스템 및 방법에 관한 것이다. 본 발명은 기지국과 제어국 사이에 새로운 신호를 정의하여 제어국에서는 핸드-오버가 발생한 시점을 기존 기지국에 알려주고 기존 기지국에서는 버퍼에 저장된 데이터가 모두 이동단말로 전송된 시점을 제어국에 알려주어서 기존 통신경로에 남아있던 데이터가 모두 이동단말에 전달되는 것을 보장할 수 있도록 한다. 또한 제어국에 핸드-오버용 버퍼를 두어서 새로운 통신경로를 구축하는 동안 수신되는 데이터를 저장하였다가 이동단말까지 새로운 통신경로가 완성되면 이 버퍼로부터 이동단말로 데이터를 전송함으로써, 이동통신망에서 하드 핸드-오버시 데이터의 유실을 막고 신뢰성 있는 핸드-오버를 지원할 수 있다.

Abstract: PURPOSE: A method for controlling call admission in mobile communication and a recording medium storing a program to realize the same are provided to efficiently use system resources and to execute discriminatory processing according to the traffic characteristics of mobile users in the case of system congestion. CONSTITUTION: If the service speed of an arrived call is fixed in case that the arrived call is a new call(S12,S13), a base station judges whether the call meets the first condition in which (Ipresent + ΔIi) is less than (Itotal - IGMreserved, new call)(S14). If the call satisfies the first condition, the base station approves the call request at a service speed of Ri(S15). However, in case that the call does not meet the first condition, the base station rejects the call(S16). Meanwhile, if the arrived call is a new call and the service speed is variable(S21), the base station judges whether the call meets the second condition in which (Ipresent + ΔImaxi) is less than (Itotal - IGMreserved, new call)(S22). In case that the call meets the second condition, the base station approves the call request at a service speed of Rmaxi(S23).

Abstract: PURPOSE: A hard handover method and system free from data loss is provided to increase service quality by preventing data loss in a hard hand-over and to efficiently operate a new hard handover method. CONSTITUTION: A base station controller(300) consists of an RRC(Radio Resource Control) layer(310) and an RLC(Radio Link Control) layer(320). The RRC layer(310) comprises a call control part(311). The RLC layer(320) comprises a buffer control part(321) and a handover buffer(322). The call control part(311) controls the buffer control part(321) with call setup and release. If a mobile terminal moves from the coverage of the first base station(100) to the coverage of the second base station(200), it is reported to the base station controller(300) through a measurement report message. Receiving the measurement report message, the base station controller(300) generates a handover. If a handover is generated, the call control part(311) stops the transmission of downlink data to the first base station(100) and directs the buffer control part(321) to store the data incoming from a core network(400) in the handover buffer(322). At the same time, the call control part(311) transmits a handover generation message to inform the first base station(100) that a hand-over has been generated.

Abstract: PURPOSE: A scheduling method for processing traffic of multi calls in a wireless communication base station channel card is provided to select one of 8 time segments, and to distribute load of traffic processing, then to efficiently treat traffic processing of the multi calls, thereby efficiently managing the traffic processing as satisfying a 3GPP standard. CONSTITUTION: A scheduling system checks whether an active call exists in an FP DL(Frame Protocol Down Link) database(501). If so, the system brings a frame offset, a chip offset, and a value of a TTI(Transmission Timing Interval) from the call(502). If the chip offset is bigger than one time segment(503), the system sets a frame position to '1'(504). If the chip offset is smaller than one time segment, the system sets the frame position to '0'(505). The system compares a value of a current CEP(Channel Element Processor) is the same as '0'(506). If so, the system decides whether another value is the same as a current time segment value(507). If so, the system processes traffic data with an exclusive channel of the call, and transmits the data to an MDSP(Modulation Digital Signal Processor)(508).

Abstract: PURPOSE: A method for managing a buffer for transport channel synchronization in a wireless communication system is provided to effective manage data coming within a process-available time window while processing traffic data. CONSTITUTION: It is checked how many buffers are turned on(401). It is checked whether the number of buffers is greater than 0(402). If the number of buffers is greater than 0, it is checked whether one buffer data with a flag ON comes within a window time(403). If one buffer data has come within the window time, the data is transferred to an MDSP(Modulator Digital Signal Processor) and the flog of the corresponding buffer is turned off(404). If one buffer data has not come within the window time, it is checked whether it has come later than a predetermined window time(405). If one buffer data has come later than the predetermined window time, the data is discarded and a flag is turned off(406). If one buffer data has come ahead of the predetermined window time, the data is stored in a corresponding buffer and a flag is maintained in an ON state(407). It is checked whether a value obtained by reducing one buffer is greater than 0(408). It is checked whether there exist data(409). If there is data, it is checked whether the data has come within the pre-set window time(410). If the data has come within the window time, the data is transferred to the MDSP(411). If the data has not come within the window time, a TA(Timing Adjustment) message is transferred to a traffic processor(412). It is checked whether certain data comes later than the pre-set window time(413). If the data has come later than the pre-set window time, the data is discarded(414). If the data has come ahead of the window time, the data is stored in an empty buffer and a flag is maintained to be ON(415).
