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: 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).

Abstract: PURPOSE: A call processing method for processor duplexing in a wireless communication system is provided to restore data of an active board in a standby board and synchronize the two boards when they are needs to be switched due to the occurrence of failure. CONSTITUTION: Initialization is performed to load a task and data related to call information are all backup(201). When a message is received, it is checked whether the message is a normal message or a duplexing related message(202). If the received message is the normal message, it is processed in an original routine and dynamic data are updated(203,204). If the received message is the duplexing related message, a standby board is switched to an active board and a dynamic/static data restoration and data synchronization algorithm is executed(205-207).
