    [23] BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a functional block diagram of an ISP message processing apparatus in an AS-T according to an embodiment of the present invention. The ISP message processing apparatus in an AS-T according to an embodiment of the present invention is TC7 (Trunk Call For No. 1). .7 Signal; hereinafter referred to as "TC7".) A processor 101, and TI7 (Trunk Interface For No.7 Signal; hereinafter referred to as "TI7") processor 102.
    [24] The TC7 processor 101 and the TI7 processor 102 are mounted in the ASS-T system 100, wherein the ASS-T system 100 is the call processing host system 10 and ASS-7 (in exchange). Access Switching Subsystem for No. 7 Signal (hereinafter referred to as "ASS-7"). It is installed between the sub-systems 20, and performs an outgoing / incoming call processing operation of the exchange-to-exchange period.
    [25] At this time, when the TC7 processor 100 mounted in the ASS-T system 100 receives a call processing message from the call processing upper system 10, the TC7 processor 100 converts the unfavorable message into an ISUP message and then the TI7 processor 102. On the other hand, when the ISUP message is received from the TI7 processor 102, the message is converted into a call processing message of an internal format of an exchanger and transmitted to the call processing higher-level system 10.
    [26] In addition, when the TI7 processor 102 mounted in the ASS-T system 100 receives an ISUP message from the TC7 processor 101, the TI7 processor 102 checks the size of the message to determine whether the message type is foreign or domestic. The ISUP message is packed in basic units and transmitted to the ASS-7 subsystem 20 while the ISUP message is transmitted to the ASS-7 subsystem 20. When receiving the message of the IPC basic unit from the system 20, it converts the message into the original size of the ISUP message and transmits the message to the TC7 processor 101.
    [27] In this case, the functions of the call processing high-level system 10 and the ASS-7 sub-system 20 mounted in the exchange will be briefly described, and the call processing high-level system 10 performs the NO.7 outgoing call processing. Serves to perform number translation and routing processing for the ASS-7, and the ASS-7 subsystem 20 serves to handle actual NO.7 signaling.
    [28] Next, a description will be given of the method of processing the ISP message in the AS-T according to an embodiment of the present invention using the ISP message processing apparatus in the AS-T having the above configuration.
    [29] First, a method of processing a forward IPS message from a home country to a large country in an ISP message processing method in an AS-T according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3.
    [30] First, the TC7 processor 101 receives a call processing message from the call processing upper system 10, converts the call processing message into an ISUP message, and outputs it to the TI7 processor 102 (S10).
    [31] Then, the TI7 processor 102 receives the ISUP message from the TC7 processor 101, detects the form of the message, and processes the message in IPC basic units according to the form (S20). Here, the basic unit of the IPC message is 4 bytes.
    [32] Hereinafter, a detailed operation process of the above-described twentieth step S20 will be described with reference to FIG. 3.
    [33] First, the TI7 processor 102 determines whether the ISUP message received from the TC7 processor 101 is greater than or equal to the maximum size of the overseas format (S21). Here, the maximum size of the overseas format of the ISUP message is 90 bytes.
    [34] At this time, if the ISUP message is smaller than the maximum size of the overseas type (NO) in the twenty-first step (S21), the TI7 processor 102 determines that the ISUP message received from the TC7 processor 101 is the maximum size of the domestic type. It is determined whether or not it is larger (S22). Here, the maximum size of the domestic type of the ISUP message is 60 bytes.
    [35] If the ISUP message is smaller than or equal to the maximum size of the domestic type in step 22 (S22) (NO), the TI7 processor 102 confirms that the type of the ISUP message is for domestic use and packs it in IPC basic units ( S23). Accordingly, the TI7 processor 102 divides the ISUP message by 4 bytes and processes the packing.
    [36] On the other hand, if the ISUP message received from the TC7 processor 101 in step 21 (S21) is greater than or equal to the maximum size of the overseas format (YES), the TI7 processor 102 has the maximum form of the ISUP message. After confirming that it is for overseas use, the packing is processed in the basic unit of the IPC message (S24).
    [37] In addition, if the ISUP message received from the TC7 processor 101 is larger than the maximum size of the domestic type (YES) in the twenty-second step (S22), the TI7 processor 102 has a maximum overseas size of the ISUP message. After confirming that the overseas use is smaller than the base unit of the IPC message packing process (S25).
    [38] On the other hand, after the 20th step (S20) described above, the TI7 processor 102 transmits a message of a raw data format packed in the basic unit of the IPC message to the ASS-7 subsystem 20 (S30).
    [39] On the other hand, in the following will be described with reference to Figure 4 a method for processing the reverse IPS message from the large station to the own country of the ISP message processing method in the AS-T according to an embodiment of the present invention.
    [40] Initially, the TI7 processor 102 receives an IPC basic unit message from the ASS-7 subsystem 20 (S100).
    [41] Then, the TI7 processor 102 checks the header information of the message of the IPC basic unit received from the ASS-7 subsystem 20 and checks the size of the message (S200).
    [42] Subsequently, the TI7 processor 102 converts the message of the IPC basic unit into an ISUP message to match the size of the header information and transmits the message to the TC7 processor 101 (S300).
    [43] Then, the TC7 processor 101 receives the ISUP message from the TI7 processor 102, converts it into a call processing message of an internal format of the exchanger, and outputs it to the call processing upper system 10 (S400).
    [44] Therefore, the result values shown in the load test of the actual ASS-T system 100 according to the present invention described above are as shown in Table 1 below, and as confirmed by Table 1 below. The occupancy rate of the TI7 processor in the system is up to twice the performance, the total CPU idle rate of the TI7 processor is improved by 5.5-8.0%, and the maximum call occupancy per hour of the existing ASS-T was "90000". Is improved.
    [45]
    [46] As described above, according to the present invention, a method for processing an IPS message in an AS-T according to the present invention and a method for processing an ISUP message in an ASS-T system, while simplifying the comparison procedure and reducing the packing procedure by a quarter, As shown in [Table 1], the process of processing the ISUP message of the ASS-T system is simplified, and the packing process is reduced to 1/4, thereby increasing the occupancy rate of the TI7 processor in the ASS-T system. In addition to improving performance twice and improving the total CPU idle rate of the TI7 processor by 5.5-8.0%, the ASS-T's maximum call occupancy rate of "90000" is up to "105000". .
