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 handover method in an advanced mobile communication system is provided to minimize the loss of packets generated in the process of an handover, to reduce handover processing delay, and to decrease network loads due to frequent registration procedures dependent on the location movement of mobile terminals. CONSTITUTION: An MN(Mobile Node) in an active state ignores a registration procedure, without executing it, even though an agent advertising message is received from a drift AS(Access Station). Instead, the MN transmits a measurement report message through an RRC connection with a serving AS. The serving AS reads channel status from the received message. If the serving AS determines the start of a handover procedure, the serving AS transmits a connection setup request message, containing physical layer configuration information and MAC configuration information for radio link setup, to the drift AS. Receiving the connection setup request message, the drift AS allocates a radio resource according to the received configuration information and executes MAC entity setup and radio link setup to support the transmission of data.
Abstract translation: 目的：提供高级移动通信系统中的切换方法，以最小化在切换过程中产生的分组丢失，减少切换处理延迟，并且由于频繁的登记过程而导致的网络负载减少，这取决于移动的位置移动 终端。 构成：即使从漂移AS（接入站）接收到代理广告消息，处于活动状态的MN（移动节点）也忽略注册过程而不执行注册过程。 相反，MN通过与服务AS的RRC连接来发送测量报告消息。 服务AS从接收的消息中读取信道状态。 如果服务AS确定切换过程的开始，则服务AS向漂移AS发送包含用于无线电链路建立的物理层配置信息和MAC配置信息的连接建立请求消息。 接收到连接建立请求消息后，漂移AS根据接收到的配置信息分配无线资源，执行MAC实体建立和无线链路建立，支持数据传输。

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 method for controlling a soft handover path in a mobile communication network is provided to set SVC connections in RNCs(Radio Network Controllers) during soft handover between the RNCs, and to previously set PVC connections in a G(Global)-RNC, thereby reducing connection setup time to supply a high-speed soft handover function. CONSTITUTION: An LIM(Link Interface Module)-N resource management processor dynamically selects usable connection identifiers among VPIs/VCIs included in an RNC of the other party, and sets connections(601). The RNC sets an operation management message path(602). A loading path is set to a basic value determined in an ATM interface, and preparation for processing a connection control request from an application program is completed(603). An LIM-N sets cells in a bypass mode(604). A G-RNC completes a connection setup function(605), and enables a remote operation management message and a control message to be transmitted(606).
