Abstract:
PURPOSE: A method for restarting ATM(Asynchronous Transfer Mode) PVC connection in an open ATM switching system is provided to promptly restore connection information even if a switching system or work station is gone down. CONSTITUTION: If an AIM(ATM Interface Module) is gone down, a GSCCF(GSMP Slave Connection Control Function)(242) of an SMC(Switch Management Controller)(24) resets ATM PVC(Permanent Virtual Connection) with having connection information existing in a memory database. If the SMC(24) is gone down, the GSCCF(242) of the SMC(24) resets ATM PVC point-to-point and point-to-multipoint connection to the AIM with connection reset information and restores ATM PVC point-to-point and point-to-multipoint connection information in a database existing in the SMC(24). If a work station is gone down, a TMN(Telecommunication Management Network) agent(15) reconstructs an MIB(Management Information Base) with root and leaf connection information which are point-to-point and point-to-multipoint connection information searched for from a database of an ACC(ATM Call Controller).

Abstract:
PURPOSE: A device of controlling a switch connection for a P-T-MP(Point To Multipoint) call of a fixed connection line in an open switching system is provided to perform PVC P-T-MP call connection setup/cancellation for a call control part of an upper controller and a control part of a lower switch, thereby using an interface for controlling the lower switch without any correction. CONSTITUTION: GSMP(General Switch Management Protocol) controllers(111,121) generate connection management messages for a P-T-MP call of a fixed connection line. A GSMP slave protocol processing module(131) decides types of the connection management messages. A switch connection control module(133) confirms a connected state of a switch according to the decided types of the messages, and creates/cancels routing tags for connecting the switch. Device controllers(141,143) connect the switch according to the routing tags. The GMSP controllers(111,121) generate messages showing connection setup, cancellation, verification, and changes for the P-T-MP call of the fixed connection line.
Abstract:
PURPOSE: A media gateway logic port ID structure and a construction method thereof in an open ATM exchange are provided to secure openness that a call processing application program does depend upon a complex system physical link structure by constructing a logical media gateway port ID being represented identically irrespective of a connection structure and a characteristic of a physical link, thereby enhancing portability of a program and extensibility of a system. CONSTITUTION: A physical port region(201) is a kind of physical link information region. The physical port region(201) comprises a media gateway(MG) number(204) as a serial number of an MGS(Media Gateway Subsystem) in a system hardware shape, an interface module(IM) number(205) representing a board number within the MGS and a link number(206) as a serial number of a physical link connected within the IM. The MG number comprises 8-bits. The IM number(205) comprises 4-bits since 16 boards can be mounted to one MGS. The link number(206) comprises 4 bits capable of mounting maximum 16 links. In a logical port management block, the physical port region(201) is used for a communication with an MMCA(Media-gateway Module Control Assembly) of the MGS controlling directly a position of a real physical port or a shape management block. A control processor region(202) controls the port and allocates a processor number of an MGC(Media Gateway Controller) for controlling a call processing function through the port. A storage index region(203) is a portion stored an index for storing logic port information in the MGC logical port management block.
Abstract:
PURPOSE: A method for summarizing a default address of the lowest level node in a PNNI(Private Network-Network Interface) of an ATM(Asynchronous Transfer Mode) switching system is provided to summarize a reachable address for a node almost to the length of an internal prefix, when the PNNI is applied to a public network. CONSTITUTION: Databases for storing prefix information, node information and reachable address information are generated. A parameter for generating an internal prefix is received and arranged appropriately for a system. The availability and an address system of the parameter are checked to generate prefix information and register the prefix information in the prefix information database. A parameter for generating node information is received, and the availability and an address system of the parameter is checked to generate an AESA(ATM End System Address). If an internal prefix is included in the AESA and a node address is decided not to be allocated yet from a digit state of the AESA, node information is generated using the node information generating parameter and the AESA, and the node information is registered in the node information database. Summary to the bit length of the internal prefix is performed using a node address in the node information, and the internal prefix is defined as a default reachable summary address, thereby summarizing the default reachable address.
Abstract:
PURPOSE: A method for controlling originating/incoming local calls is provided to set up a call by the unit of 64Kbps B-channel for digital subscribers, and to integrate switching systems using mutually different transmission system. CONSTITUTION: A time switch is connected for basic subscribers mounted in an ATM(Asynchronous Transfer Mode) switching system, basic connection multiplexing, and a digital subscriber line of a basic subscriber interface. Signals of a digital subscriber signaling system of a digital subscriber terminal are processed. Speech data of a call control for digital subscribers are turned to ATM cells. An IAAL(IPC(Inter Processor Communication) ATM Adaptation Layer) conversion is performed for the speech data, for IPC(Inter Processor Communication) transceiving between a digital subscriber control system and a call control processor of an ATM system. Signals between the digital subscribers and a network, and internal signals are processed by transceiving a signal message using the IAAL.
