A sub-system (Access Switching Subsystem for Packet Switching: ASS_P) (1-2), a processor in charge of packet subscriber access exchange (Access Switching Processor for Packet: hereinafter called ASP_P) (1-21), Module responsible for packet processing ( Packet Handling Module (hereinafter referred to as PHM) (1-22), Processor for controlling packet layer (Packet Layer Control Processor (hereinafter referred to as PLCP)) (1-23), Time Switch Processor (hereinafter referred to as TSP) (1-24), the internal connection network subsystem (hereinafter referred to as INS) (1-3), and the processor in charge of the internal connection network (hereinafter referred to as NTP) (1-) 32, a database (hereinafter referred to as DB) 1-4, a time switch TSW, a space switch S-SW, and a space switch processor SSP.

In addition, such hardware includes a software block necessary for processing a virtual line service B-channel packet local call, and an ASP_I (1-13) block for digital subscriber packet mode control (Digital Subscriber Packet). mode control (hereinafter referred to as DPC), a block for digital subscriber matching (hereinafter referred to as DSI) in the ISAP 1-12, and a time switch link in the TSP 1-14. In the ASP_P (1-21), there are packet inward_call control (PIC) and packet call direction control (PDC) blocks that perform functions such as packet call control / verification and number translation request. In (1-22), a block (B-channel X.25 Protocol Handler: hereinafter referred to as B25H) that performs link layer and packet layer execution of the X.25 protocol is referred to as a B-channel packet to the PLCP (1-23). Block in charge of call control (B-channel Packet Call Control: BPCC In the TSP (1-24), a time switch link (hereinafter referred to as TSL) block, and in INP (1-31) a switch network control block (hereinafter referred to as SNC), NTP (1-32) is equipped with a block responsible for number translation (Number TRanslation: NTR hereinafter).

A high speed selection processing method in a limited method among packet random user functions in the integrated information communication network packet system having the above configuration is as follows.

First, if the subscriber selects the fast method of the limited method and requests the call setup, the ASP_P (1-21) is passed through the IDPA (1-11) through the DSI of the ISAP (1-12) and the DPC of the ASP_I (1-13). Notified by PIC. The PIC sets up the calling physical path and sends it to the BPCC of PLCP (1-23) .The BPCC investigates the calling party's status and subscriber information according to the calling physical routing completion notification and determines the originating call and requests call establishment. The packet is waiting to be received.

When the originating signal is possible, when the call establishment request packet is received from the originating terminal to the originating B25H (hereinafter referred to as B25Ho) of the PHM (1-22), the verification of the call establishment request packet is requested to the originating BPCC (hereinafter referred to as BPCCo). At this time, BPCCo sends the result of reassembly after disassembly and verification of call setup request packet to B25Ho.

Also, BPCCo requests number translation and destination physical path establishment request by PDC and PIC of ASP_P (1-21) (2-3). Therefore, PIC requests destination B-channel by DPC and sets incoming B-channel. Set it. After the B-channel is set up, the PIC sets up the called party's physical path and informs the BPCC of the setup result. As a result, the BPCC examines the subscriber status and information to determine whether the call is generated.

In this case, when the incoming call can be generated, the receiving logical channel is allocated and the result is notified to the BPCCo to inform the calling terminal that the originating party can send the incoming call.The called party disassembles and reassembles the incoming call packet and verifies the result of its B25H (hereinafter referred to as B25Ht To be transmitted to the called terminal.

Accordingly, the called terminal requests the call release after receiving the user data in the limited method, and the BPCCo transmits the call setup request packet verification result according to the called logical channel assignment notification and reaches the released state.

Next, a high speed selection processing method using an unlimited method among packet random user functions in the integrated information communication network packet system having the above configuration will be described.

First, if the subscriber selects the fast method of the unlimited method and requests the call setup, the ASP_P (1-21) is passed through the DPA of the ISAP (1-12) and the DPC of the ASP_I (1-13) through the IDPA (1-11). You will be notified by PIC. PIC sets the calling physical path and informs BPCC of PLCP (1-23), and BPCC investigates calling party status and subscriber information according to calling physical path establishment completion notification and determines call origination and requests call establishment. The packet is waiting to be received.

When the originating signal is possible, when the call establishment request packet is received from the originating terminal to the originating B25H (hereinafter referred to as B25Ho) of the PHM (1-22), the verification of the call establishment request packet is requested to the originating BPCC (hereinafter referred to as BPCCo). At this time, BPCCo sends the result of reassembly after disassembly and verification of call setup request packet to B25Ho.

In addition, BPCCo makes a number translation request to the PDC and PIC of the ASP_P (1-21) and the destination physical path establishment request. Accordingly, the PIC requests the destination B-channel establishment request to the DPC to configure the destination B-channel. After the B-channel is set up, the PIC sets up the called party's physical path and informs the BPCC of the setup result. As a result, the BPCC examines the subscriber status and information to determine whether the call is generated.

At this time, if the incoming call can be generated, the destination logical channel is allocated and the result is notified to the BPCCo to inform the calling terminal that the call is possible. To be transmitted to the called terminal.

When a call reception packet is received from the called terminal to the called BPCC (hereinafter referred to as BPCC), the packet is disassembled, verified, and reassembled.

Accordingly, B25Ht transmits the result to B25Ho with reference to the received call reception packet.When a request for call connection packet verification is received by BPCCo, the B25Ht disassembles, verifies and reassembles the call connection packet, and sends the result to B25Ho to send the call to the calling terminal. Allow notification of connection results. This leads to a packet call connection state.

2A to 2B are detailed flowcharts of the start / arrival signal setting processing according to the present invention.

Since the BPCC is responsible for the fast selection processing in the limited and unlimited methods according to the present invention, only the contents of the BPCC will be described.

When the subscriber requests the fast-selection function of the limited or unlimited method, upon receiving notification of the completion of the originating physical path setting from the PIC (201), the BPCC accesses the database and reads information on the calling party to create the calling process. After making the basic data (202), it is determined whether the originating process can be generated, and prepares for the creation of the originating process (BPCCo) (203).

At this time, if a verification request for the call establishment packet is received from B25Ho (204), the call establishment request packet is decomposed (205) to verify whether the subscriber requests the fast selection of the limited method or the fast selection of the unlimited method. Perform 206.

As a result of the verification of the fast selection method, if the subscriber requests fast selection of the limited method, it is verified whether the fast selection is registered in the exchange by referring to the value of accessing the database (207, 208).

As a result of the verification of the registration, if not registered, the process proceeds to the incoming call release response process 254. If the registration is registered, the user data requested by the subscriber is 128 bytes or less (209), and if it is 128 bytes or more. In the incoming call release response process (254), the call is released, and if the user data is 128 bytes or less, the called party number translation is requested by the PDC (210). When the recipient number translation result is notified (211), the receiver prepares for the physical physical path request (212) and requests the physical path for the destination (213). Upon receiving notification of the completion of the logical channel allocation, the BPCCo notifies the B25Ho of the verification result of the call establishment request packet (214) and transitions to the call release process (253, 256).

As a result of the verification of the fast selection method, if the subscriber requests fast selection of the limited method, it is verified whether the fast selection is registered in the exchange by referring to the value of accessing the database (217 and 218).

As a result of the verification of the registration, if not registered, the process transitions to the process stop process 265, and if registered, the user data requested by the subscriber is 128 bytes or less and is checked (219). Transition to the incoming call release response process 254 to release the call and if the user data is 128 bytes or less, the call number translation is requested to the PDC (220). If the recipient number translation result is notified (221), the receiver prepares for the physical path establishment request (222) and requests the physical path establishment of the called party (223). Upon receiving the notification of the completion of the logical channel allocation, the BPCCo 224 reassembles the call setup request packet and prepares for the result notification (225). The BPCCo notifies the verification result of the call setup request packet to the B25Ho (226). In addition, after receiving the verification request for the call connection packet from B25Ho, the BPCCo disassembles the call connection packet (227) and verifies the packet (228). Then, the BPCCo notifies the call originating packet verification result to B25Ho, and the call is connected to the calling terminal. (229). Thus, after the call connection state including the fast selection function requested by the subscriber is established (230), the call release process (264) is performed.

On the other hand, when the called party's physical path is established and notified of the result (231), after accessing the called party's database to read information about the called party (232), it is determined whether the called process can be generated and then called according to the result. A process creation (hereinafter referred to as BPCCt) is prepared (233). When the terminating process generation is completed, the terminating logical channel is allocated (234), and the result of the terminating logical channel allocation is notified to BPCCo (235). In addition, the BPCCt requests the establishment of the incoming link to B25Ht in order to establish the destination layer 2 (236). After being informed of the result of the incoming link establishment, the BPCCt enters the standby packet waiting state (237).

In addition, the BPCCt decomposes the incoming call packet according to the incoming call packet verification request received from the B25Ht (238) and verifies whether the user data is included (239) to request the fast selection of the limited method. Check if required (240).

As a result of the verification of the fast selection method, if the fast selection of the limited method is required, it is checked whether or not the incoming subscriber has registered the fast selection function inside the exchange (241, 242). When the call is released and the call is registered, the incoming call packet is constructed (243) so that the user data in the received incoming call packet and the fast selection code of the limited method are delivered to the called party (243). Is transmitted to the called terminal by transmitting to B25Ht (244). As a result, the user data to be transmitted from the calling party is transmitted to the called terminal simultaneously with the call setup.

Since the called terminal receives the user information in the limited method after completing the reception of the user information, the terminating terminal makes a release request to terminate the call (253). BPCCt notifies B25Ht of the response to the call release (254) and terminates the incoming process (255). In addition, the B25Ht notified of the call release response notifies the B25Ho that the incoming call has been released so that the call release request is transmitted to the BPCCo (256). Accordingly, the B25Ho is notified of the response to the originating process release (257) and the originating process is destroyed (258).

After the process expires, the BPCC sends a link release request to the B25H to release the occupying Layer 2 resource (259) and after receiving the result (260), requests the physical path to the PIC (261). Upon receiving the physical path release completion notification (262), all information related to the link is initialized (263).

On the other hand, as a result of the verification of the fast selection method, if the fast selection of the unlimited method is required, it is checked whether the incoming subscriber has registered the fast selection function in the exchange (245, 246). In step 265, the call is released and if it is registered, the incoming call packet is reassembled so that the user data in the received call packet and the fast selection code of the unlimited method can be delivered to the called party (247). The packet packet verification result is transmitted to the B25Ht to be transmitted to the called terminal (248). Thus, the user data to be transmitted from the calling party is transmitted to the called terminal at the same time as the call setup.

After the incoming packet is transmitted, the B25Ht receives a call reception packet as a response from the called terminal, and then sends a verification request to the BPCCt (249). Accordingly, the BPCCt decomposes the call reception packet to perform its verification (250) and notifies the result of the call to B25Ht (251), so that the incoming process transitions to the data delivery state (252).

If the subscriber makes a call release request to terminate the call after completing the data delivery (264), the BPCC stops (265) the process (the originating or incoming process that received the call release) and occupies the occupying Layer 2 resource. A link release request is sent to B25H to release (266) and after receiving a link release result (267), a physical path release request is requested to the PIC (268). When the physical path release completion notification is received (269), all information related to the link is initialized (270).

Therefore, according to the present invention performed by the above-described processing procedure, the user data is transmitted at the same time the call is connected, so that the subscriber who does not need much packet data delivery releases the call after only delivering the user information, thereby reducing the occupancy time of the system. It can minimize the load on the system and reduce the burden on the subscribers according to the communication policy. Also, the user data is delivered by making the call the day before the call is connected. Data packets can be continuously delivered afterwards, and according to the development of communication network technology, it is possible to give ISDN packet subscribers various opportunities in the future.
