Abstract:
PURPOSE: A method for processing triggering detection point information of an IMT-2000(International Mobile Telecommunication-2000) system is provided to transmit the triggering detection point information to the IMT-2000 system by using a No.7 signal network, so as to supply a new intelligent network service, without correcting a software within the system. CONSTITUTION: A triggering detection point information processor receives a triggering detection point information transmitting message transmitted from an intelligent network service control system(S31). If an operation type value of the received message is a detection point activation(S32), the processor checks whether an idle condition area exists(S33). If so, the processor stores receiving condition information(S34), and notifies the control system that triggering detection point information is successfully activated(S35). If the idle condition area does not exist, the processor notifies the control system that the triggering detection point information is not activated(S36). If the operation type value is a detection point deactivation, the processor checks whether a condition area equal to the receiving condition information exists(S37). If so, the processor initializes the condition area(S38), and notifies the control system that the triggering detection point information is successfully deactivated(S39). If the condition area does not exist, the processor notifies the control system that the triggering detection point information is not deactivated(S40).

Abstract:
PURPOSE: A method for processing a directly terminated call in an originating-dedicated CT-2 is provided, in CT-2 directly terminating system, to offer a direct terminating service to a subscriber by managing the location data of the user. CONSTITUTION: In an originating-dedicated CT-2 for processing a signal terminated among the originating CT-2 terminal(MS), CT-2 base station(BS), CT-2 base station controller(BSC), CT-2 exchange(CTX) and CT-2 subscriber data manager(CTH), if the CT-2 exchange recognizes the call is terminated to CT-2 terminal, it performs an originating signal process and makes inquiries about the location data of the terminal to CTH. Then, CTX requests a terminal paging to the received location data. If the terminal receiving the terminal paging responds to the base station, the base station responds to BSC, then the BSC to CTX. The CTX receiving the paging response performs a terminating signal process and performs a terminating signal setting with the MS in order to connect a wireless/wired channel between the terminal terminated and the CTX. The originating subscriber and the CT-2 terminal talk with each other through the connected channel.
Abstract:
PURPOSE: A method for controlling local handover for a personal communication subscriber in a narrow-band ISDN(Integrated Services Digital Network) exchange is provided to re-allocate one speech path between both subscribers and release an existing speech path, and to use a handover encryption so as to improve handover reliance. CONSTITUTION: If handover is requested, a handover address is checked to decide whether the handover address is included in a local station. Whether a speech path for handover and a wireless channel are secured is confirmed. If not secured, a handover failure is notified to a terminal. If secured, an HRN(Handover Random Number) is generated and transmitted to the terminal. The terminal performs handover, and confirms whether the HRN is equal to the HRN to be transmitted. And the terminal releases an existing speech path and a wireless channel, and maintains new speech path and wireless channel, thereby ending handover.
Abstract:
PURPOSE: A terminal for testing a service function of a facsimile and method for operating the terminal are provided to test the service function thereof which an interlocking device for a data service via a wireless phone of the second generation offers, by testing a protocol standard of a modem signal between an application program for a facsimile service and the interlocking device, according to a facsimile service request from the application program. CONSTITUTION: A facsimile service controller(11) receives a request for the service via an EIA-232 interface(12), and performs an emulation function. Facsimile data is switched by a switching part(13) to be transferred to a modem pool in the interlocking device via a corresponding channel at a framer(14). The framer(14) is interfaced with the interlocking device, and receives a trunk from the interlocking device in order to convert it to a digital signal. A ST-bus synchronization signal generator(15) provides a synchronization signal to the switching part(13) and framer(14). An ISA interface(16) receives and transmits a call control signal via an ISA bus which is a system bus of a personal computer.
Abstract:
PURPOSE: An apparatus and a method for processing a signal protocol to verify a mobility of an international mobile telecommunication (IMT) exchange are provided to verify the mobility of the exchange without an additional network element, and utilize the exchange for an asynchronous transfer mode (ATM), by developing the mobilities of a mobile terminal and a base station with integration. CONSTITUTION: If a message for a mobility and terminal access controls is received (111), it is determined to be valid (112). If the message is not valid, an error process is performed (113), and otherwise a transaction identifier and terminal managing message are generated (114) prior to transmission to an ATM mobile exchange (121). If a valid call process message is received (115,116,113), a call reference number is generated and converted to a Q.2931 message (117). The Q.2931 message is transmitted to the exchange (121). If a bearer message is received (118), the validity check process and error process are performed (119,113). The bearer message is converted to a mobility added message (120) prior to the transmission (121). If a control message is received (122), and it is determined to be valid and a type of the control message is classified (123).
Abstract:
PURPOSE: An apparatus and method for processing packet in CT-2 data service interlocking system is provided to secure a service competitive power by adding a modem signal emulation function using a software to a conventional CT-2 terminal without a change of hardware and software of a base station in a CT-2. CONSTITUTION: A preamble sensing and adding/removing module(104) senses a preamble from a signal inputted from an exchange of a CT-2 base station to remove the sensed preamble and outputs the removed signal to a FIFO unit(105). The preamble sensing and adding/removing module(104) adds a preamble to a signal inputted from the FIFO unit(105) and outputs the added signal to the exchange of the CT-2 base station. A data packet control module(101) extracts a data control message from a signal inputted from the FIFO unit(105) and outputs a control signal corresponding to the extracted control message to a modem matching module(102) to control the modem matching module(102). The modem matching module(102) assigns a modem according to the control signal inputted from the data packet control module(101), assigns a channel to compose a communication path, and transmits and receives data through the composed communication path.
