    [13] The present invention relates to a method of transmitting call information between a mobile communication exchange and an interworking function (IWF). In particular, the wireless data service can transmit and receive information on an ongoing data call through a request and response message between the mobile communication exchange and the IWF. The present invention relates to a method of transmitting call information between a mobile communication exchange and an IWF.
    [14] 1 is a block diagram of a general mobile communication network, in which a mobile communication network related to a wireless data service includes a mobile station (1), a base station (2), a control station (3), an exchange station (4), and a home location register (HLR) (5). And an IWF 6, wherein the switching center 4 interworks with a CDMA network 7 and a PSTN 8, and the IWF 6 Interworking with the Public Switched Data Network (PSDN) 9 and the Internet network 10.
    [15] FIG. 2 is a block diagram illustrating a hardware block configuration of an ASS (Access Switching Subsystem) -IWF in the switching center 4 and includes two Peripheral Processor Interface Assemblies (PPIAs) for controlling a Frame Relay Interface (FRI) and a Primary Rate Interface (PRI). 11-1, 2, six FRIs 12-1 to 6 for packet data call processing, and two PRIs 13-1 and 2 for circuit data call processing.
    [16] 3 is a main software block configuration diagram mounted on the hardware block of the ASS in the exchange station 14, and the ASS-M 21 for matching with the control station 3 controls call processing for the mobile station. Mobile Call Control (MCC) 21-1, and the ASS-T 22 for trunk matching with the PSTN 8 controls TCR, TC7 (for controlling call processing performed on the PSTN 8). 22-1), and the ASS-IWF 23 for matching with the IWF 6 controls IWF Call Control (ICC) 23-1 and IWF for controlling call processing for packet data and circuit data. And an IWf Interface (IWI) 23-2 for performing matching with (6).
    [17] The ICC 23-1 is in charge of interworking with the IWF 6 for wireless data call connection, supports a PRI composed of Q.931 of DSS-1 according to a path connected with the PSTN 8, and calls Generate basic data for billing, statistics, and status management functions that occur during control.
    [18] A packet mode data service is provided between the control station 3 and the IWF 6 through a path connected to the MCC 21-1, the ICC 23-1, the IWI 23-2, and the IWF 6. And is connected between the IWF 6 and the PSTN 8 to the IWF 6, the IWI 23-2, the ICC 23-1, the TCR, TC7 22-1, and the PSTN 8. Circuit mode data service is performed over the path.
    [19] As described above, the mobile communication switch in the switching center 4 of the mobile communication network performs call processing for packet data and circuit data, that is, FR call data and PRI call data through the ICC 23-1 of the ASS-IWF 23. Thereby performing a wireless data service.
    [20] On the other hand, when performing the wireless data service in the switching center 4 of the mobile communication network, the signal of the mobile communication switch is conventionally used to manage information on the data call.
    [21] That is, the call information transmission method between the conventional mobile communication switch and the IWF 6 will be described with reference to the signal flow diagram shown in Fig. 4, first of all the ASS-IWF 23 in the exchange station 4 is completed. The order in which the FR Child Process 31 in the ICC 23-1 receives the call information of the PRI is as follows.
    [22] The relevant information is collected by the PRI child process 33 in the ICC 23-1 and transmitted to the FR main process 32 in the ICC 23-1 using the signal PRI_Connect.
    [23] Then, the FR main process 32 finds the FR child process 31 corresponding to the PRI child process 33 through the table managing the FR child process 31 and transmits the call information of the PRI received through a signal called PSTN_Connect. send.
    [24] The call information of the PRI is appropriately used for billing and statistics, thereby facilitating call processing and operation of the mobile communication exchange.
    [25] And, the call information of the FR can be obtained when the PRI child process 33 receives the signal PRI_ConnectAck from the FR main process 32.
    [26] However, the call information of the FR received by the PRI child process 33 is necessary information at the beginning of the PRI call processing, and is not very necessary when the data call processing is completed.
    [27] Here, the information of the transmitted call is a call type, called and received information of the mobile station, information of the called party (local network, foreign network, PSTN), type of billing, exchange information of the called party, destination base station information, mobile station information, and the like. There is this.
    [28] As described above, in the case of the call information transmission method between the conventional mobile communication exchange and the IWF 6, the FR child process 31 management table must be used in the FR main process 32. Since call information is transmitted and received in the finished state, both the FR child process 31 and the PRI child process 33 have a problem in that it is difficult to transmit and receive information of a required data call in a timely manner.
    [29] SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to generate a request and response message according to the FR Q.933 message standard and the PRI Q.931 message standard between the mobile communication exchange and the IWF during wireless data service. The purpose of the present invention is to provide a method of transmitting call information between a mobile communication exchange and an IWF to assist in maintaining and operating a call by transmitting and receiving call information.

    [33] The call information transmission method between the mobile communication switch and the IWF according to the present invention will be described with reference to FIGS. 5 to 7 as follows.
    [34] First, in the call information transmission request step S1 of the PRI, the FR child process 31 in the ICC 23-1 of the ASS-IWF 23 in the switching center 4 transmits the call information of the PRI as a message of Q.933. Send a PRI Call Info Inquiry message to the IWF (6).
    [35] After the call information transmission request step (S1) of the PRI, the message change and transmission step (S2) proceeds, and the IWF (6) receives the PRI Call Info Inquiry message transmitted in the step (S1). Change to the message and send to PRI child process 33.
    [36] After the message change and transfer step S2, the process proceeds to the call information transfer step S3 of PRI, and the PRI child process 33 receives the PRI Call Info Inquiry message from the IWF 6 transmitted in step S2. Afterwards, the call information of the corresponding PRI is transmitted to the IWF (6) in the PRI Call Info message of Q.931.
    [37] After the call information transmission step (S3) of the PRI, the message change and transmission step (S4) proceeds, and the IWF 6 receives the PRI Call Info message transmitted in the step S3, and converts the header to the message of Q.933. After the change, it is sent to the FR child process 31.
    [38] The Q.933 PRI Call Info message is used appropriately for billing and statistics in the FR child process 31 to make the use of the information of the wireless data call transparent.
    [39] In this case, the details of the PRI Call Info Inquiry message and the PRI Call Info message used in Q.933 and Q.931 are shown in FIG.
    [40] Subsequently, in the FR call information transmission request step S5, the PRI child process 33 in the ICC 23-1 of the ASS-IWF 23 in the switching center 4 transmits the FR as a message of Q.931. The FR Call Info Inquiry message requesting the call information transmission is transmitted to the IWF (6).
    [41] After the FR call information transmission request step S5, the message change and transmission step S6 is carried out, and the IWF 6 receives the FR Call Info Inquiry message transmitted in the step S5 and transmits the header to Q.933. Change to the message and send it to the FR child process 31.
    [42] After the message change and transfer step S6, the process proceeds to FR's call information transfer step S7 and the FR child process 31 receives the FR Call Info Inquiry message from the IWF 6 transmitted in step S5. Then, the corresponding FR call information is transmitted to IWF (6) in FR Call Info message of Q.933.
    [43] After the call information transmission step (S7) of the FR proceeds to the message change and transmission step (S8), the IWF 6 receives the FR Call Info message transmitted in the step (S7) to the header of the message of Q.931 After the change, it is sent to the PRI child process 33.
    [44] The FR Call Info message of Q.931 is appropriately used for call processing and statistics in the PRI child process 33 to make the use of the information of the wireless data call transparent.
    [45] In this case, the details of the FR Call Info Inquiry message and the FR Call Info message used in Q.933 and Q.931 are shown in FIG.
    [46] The information received from the FR child process 31 as described above is the service option information of the call, and is information currently known only to the FR child process 31.
    [47] The method of transmitting the service option information is not present in the message of Q.931, but is necessary information for data service on a smart phone later.
    [48] Upon receiving the service option information, the PRI child process 33 uses the service option information to find the corresponding mobile station when paging the destination mobile station, and the receiving mobile station which receives the service option information automatically corresponds to the service option. The data service can change the state of the mobile station.
    [49] As described above, the method of transmitting call information between the mobile communication exchange and the IWF according to the present invention is a process of receiving the call information of the PRI by the request of the FR child process 31 and the call of the FR by the request of the PRI child process 33. It is a process of receiving information, especially when the IWF 6 negotiates each call processing.
    [50] That is, since the IWF 6 recognizes the FR and PRI calls as one radio data call, data is exchanged between the mobile communication exchange and the IWF 6 after judgment and negotiation on the FR and PRI call processing. Share information about the call.
    [51] As described above, the present invention, by providing a request and response message between the mobile communication exchange and the IWF during the wireless data service can transmit and receive the information of the data call in progress to help the maintenance and operation of the call, through the IWF There is an effect that can increase the consistency of the data call.
