Abstract:
PURPOSE: A method for processing a reservation call in a mobile ATM virtual channel switching system is provided to process a reservation call between an ATM virtual channel switching system and a base station controller or the ATM virtual channel switching system and a home location register. CONSTITUTION: A method for processing a reservation call in a mobile ATM virtual channel switching system comprises the following steps. A corresponding subscriber interface block requests the call reservation for a subscriber to a home station register requests when the subscriber requests the call reservation. The user interface block receives a call reservation confirmation message and transmits a call reservation confirmation message to a base station controller. The subscriber interface block receives a call request message from the subscriber and searches a communication line. The subscriber interface block transmits the call request message to the base station controller and recovers the connection if the communication line is searched.

PURPOSE: A method for processing a standby call in a mobile ATM virtual channel switching system is provided to process a standby call between an ATM virtual channel switching system and a base station controller or the ATM virtual channel switching system and a home location register. CONSTITUTION: A method for processing a standby call in a mobile ATM virtual channel switching system comprises the following steps. A service for a third subscriber is performed by requesting a second subscriber's information when the third subscriber requests information of the second subscriber connected a first subscriber. A virtual channel is set up to perform the connection between the second subscriber and the third subscriber. A guide broadcasting is transmitted to the first subscriber after reserving the connection between the first subscriber and the second subscriber. A new call connection is performed between the second subscriber and the third subscriber. The second subscriber is disconnected to the third subscriber according to a request of the disconnection from the second subscriber.
Abstract:
PURPOSE: A remote loading method to a hanvit ACE 64 ATM-RSS switching system from a hanvit ACE 64 ATM switching system is provided to operate the hanvit ACE 64 ATM-RSS switching system normally, as the hanvit ACE 64 ATM-RSS switching system loads necessary information from a hanvit ACE 64 ATM switching system, using traffic channels between the hanvit ACE 64 ATM switching system and the hanvit ACE 64 ATM-RSS switching system. CONSTITUTION: In the event of the failure of a first storage unit under the operation of a hanvit ACE 64 ATM-RSS switching system(13), loading is requested to a hanvit ACE 64 ATM switching system(14). According to the loading request of the hanvit ACE 64 ATM-RSS switching system(13), the hanvit ACE 64 ATM switching system(14) accesses a second storage unit and transmits the loading data stored in the second storage unit to the hanvit ACE 64 ATM-RSS switching system(13). The hanvit ACE 64 ATM-RSS switching system(13) carries out a loading procedure according to the loading data from the hanvit ACE 64 ATM switching system(14) and stores the loading data in the first storage unit.
Abstract:
PURPOSE: A method for overcoming ethernet communication fault in the duplicated switching system is provided to ensure the continuity of service only with the transfer of the duplicated switching system without using additional hardware to process a fault of the ethernet communication. CONSTITUTION: If a user application program requests message transmitting through SROS (Scalable Real-time Operating System)(301), an ethernet server processes the related protocol(302). In case that a hardware controller informs the generation of a link fault(303), an ethernet device driver transmits a packet(304). In case that the link fault has been confirmed, the control is handed over to a link fault processor(309). If the interrupts generated after the ethernet device driver transmits a packet are all normal transmitting complete, a link fault counter and a link fault transfer variable are initialized(307,308). A link fault management part of the ethernet server increases the link fault counter(309). If the increased link fault counter does'n't exceed an appointed maximum value, the user application program requests the next message transmitting(310). If the increased link fault counter exceeds an appointed maximum value, the link fault counter is initialized and the transfer is tried(311).
Abstract:
PURPOSE: A mutual exclusion method of a lock waiting information is provided to detect a deadlock occurred when a lock waiting information is commonly accessed by a deadlock detector and transactions in a DBMS by using a transaction table and the lock waiting information. The method can make the lock waiting information just by a static assignment of many transaction elements by setting properly the number of the static elements according to the system characteristics. CONSTITUTION: A mutual exclusion method of a lock waiting information comprises steps of using a latch on the lock waiting information pool as the mutual exclusion means, initializing the system, performing a lock waiting process in the case that a waiting lock is obtained by other transaction when a transaction requests a lock, performing a lock acquisition process, performing a lock return process, and performing a deadlock detection process with one of the above processes.

CONSTITUTION: A switch(220) provides a turn-off function between an audio processing module(210) and a speaker/mike(23) and generates a data processing path. A data matching module(240) amplifies a data signal inputted from the audio processing module(210) stably to output the amplified data signal and amplifies data inputted from the outside stably to output the amplified data to the audio processing module(210).
Abstract:
PURPOSE: An apparatus and method for matching trunk and switching channel in CT-2 data service interlocking system are provided to secure a reliability of a CT-2 data service interlocking system by transmitting data received through a channel assigning, a traffic data switching function and a modem to a subscriber terminal device and transmitting a modem negotiating signal and a traffic data to a CT-2 terminal. CONSTITUTION: A framer(101) is matched with an exchange through an E1 CEPT, and receives an E1 trunk input data received from the exchange. The framer(101) converts the received E1 trunk input data into a digital signal and extracts a synchronizing clock to perform a signal synchronizing function between the exchange and a data service interlocking device. A switching module(102) outputs a signal inputted from the framer(101) to a trunk and switching module(103), forms a path between E1 stations according to a control signal inputted from the trunk and switching module(103), and divides a data and modem control signal into a service data and modem control relation signal information. A buffer(102) performs a buffering of a signal inputted from the trunk and switching module(103). A synchronizing signal generating module(105) provides clocks to the switching module(102) and a buffer(104).
Abstract:
PURPOSE: A method for operating the remote shell of an enbeded real time operating system is provided to enable a number of users to use a shell by using a communication network simultaneously although the shell is not for a number of users. CONSTITUTION: A method for operating the remote shell of an embedded real time operating system is to operate a shell of a real time operating system used in a switching system. The operating system is embedded in the switching system. The method comprises: a first step of generating a request message to request a shell command performance according as a remote shell interface is not a remote shell performance end command but a command registered by inputting a shell command from the external, and transmitting the request message to a remote shell performance demon; a second step that the remote shell performance demon analyzes the request message and performs the shell command by using a shell command processing part according as the shell command is a registered command; a third step that the remote shell performance demon composes the performance result as a message and transmits the message to the remote shell interface; and a forth step that the remote shell interface receiving the performance result message generates an output message according to the performance result message and outputs the output message.
