Abstract: A method for reporting channel quality information in a wireless communication system is provided to save resources by transmitting MS(Mobile Station) information between an RS(Relay Station) which measures uplink signals of the MS and a BS(Base Station) which manages the MS information, without any additional control procedure. A BS(400) transmits a measurement request message to an RS(410) in order to direct the RS to measure uplink signals of a specific MS(420)(S450). Receiving the measurement request message, the RS transmits a measurement response message to inform to the BS that the measurement request message has been normally received(S455). Then the RS measures uplink signals of the MS and transmits a measurement report message to the BS(S460-S480).

Abstract: A method for relaying CDMA code information in a relay environment and a system thereof are provided to transmit time and power information to a BS(Base Station) through an RS(Relay Station) CDMA code so that the BS can create an RNG-RSP message. An MS(Mobile Station)(120) selects and transmits a CDMA code(C1) corresponding to one among an initial access ranging function, a handoff ranging function, a bandwidth request function, and a periodic ranging function. Receiving the CDMA code, an RS(110) adds its own relay code offset to the CDMA code, creates an RS CDMA code(R1), and transmits the RS CDMA code to a BS(100). The BS receives the RS CDMA code, subtracts the relay code offset of the RS from the RS CDMA code, and recognizes the CDMA code transmitted from the MS.

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 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 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).
