Hereinafter, with reference to the accompanying drawings, the configuration, operation and operation effects for an embodiment according to the technical idea of the invention "charge data control device of the mobile communication switch" configured as described above are as follows.

<Example>

First, as shown in FIG. 3, the CDR 51, the CDSB 52, the charging disk 53, and the charging MT 54 are connected to form an exchange unit 50, and the CDM 61 is connected. Is connected to the charging data input terminal of the CNC 62 to configure the OMID 60.

Further, the charging data output terminal of the CDSB 52 is connected to the charging data input terminal of the CDM 61 through RS-422, and the control signal output terminal of the CNC 62 is controlled by the CDSB 52. Connected to a signal input terminal, the charging data output terminal of the CNC 62 is connected to the charging data input terminal of the charging center 70 through TCP / IP and an Ethernet card, and outputs the control signal of the charging center 70; The terminal is connected to the control signal input terminal of the CNC 62 to constitute the present embodiment.

Then, the charging data and the control signal generated in the exchange unit 50 are transmitted to the charging center 70 through the CDSB 52, the CDM 61 and the CNC 62 in sequence, and the charging center The control signal generated at 70 is transmitted to the CDSB 52 via the CNC 62.

At this time, one OMID 60 is connected to each switch unit 50, and a plurality of OMIDs 60 connected to the plurality of switch units 50 are connected to one charging center 70.

Hereinafter, the operation of the present embodiment configured as described above will be described in detail.

First, the exchange unit 50 performs a polling signal detection step 100 for detecting whether a polling signal generated periodically at the charging center is received.

In this case, when it is determined that the polling signal is detected, a signal indicating whether there is charging data to be transmitted, which is transmitted from the CDR 51 to the CDSB 52 is detected, and whether the charging data to be transmitted is detected. The transmission determination step 200 is performed.

In addition, if it is determined that there is charging data to be transmitted as a result of performing the transmission determining step 200, the data transmission step 300 of transmitting the charging data to the charging center 70 through the OMID 60. To transmit the billing data.

This will be described in detail as follows.

First, when charging data for a call service provided to a subscriber is generated at the exchange, the CDR 51 controls the temporary data and temporarily stores the charging data on the charging disk 53 and transmits a signal indicating the same to the CDSB 52. (Here, the charging data stored in the charging disk 53 is stored in the charging MT 54 under the control of the CDR 51 when the information amount is a certain amount.).

Then, the CDSB 52 stores a signal indicating that there is charging data to be transmitted in a predetermined storage location.

At this time, when a polling signal is received at the charging center 70 asking whether the charging data exists to be transmitted through the CNC 62, the exchange unit 50 detects a value stored in the CDSB 52, If it is determined that there is charging data to be transmitted, the generated charging data is transmitted to the charging center 70 through the CDM 61 and the CNC 62.

Then, the charging center 70 is to process the billing data transmitted in real time to perform the billing settlement.

5 is a detailed flowchart illustrating an example of the charging data transmission process.

First, the charging center 70 is a control signal "LinkConReq" which is a connection message (MESSAGE) on a TCP / IP socket (SOCKET) and a control signal for checking whether the OMID (60) charging transmission function is operated. "PathConReq" will be sent to the OMID (60).

Then, the OMID 60 transmits the control signal "PathConfirm" which is a normal response message to the control signal "PathConReq" to the charging center 70.

Thereafter, the charging center 70 transmits a control signal "ApConReq", which is a message confirming whether the charging transmission function of the switch unit 50 is normally operated, to the CDSB 52.

Here, the control signal "ApConReq" is a message between the charging center 70 and the CDSB 52. Hereinafter, all the control signals described below are messages between the charging center 70 and the CDSB 52.

When the control signal "ApConReq" is received by the CDSB 52, the CDSB 52 is transmitted to the charging center 70 by the control signal "ApConfirm" which is a normal response signal to the control signal "ApConReq".

Then, the charging center 70 transmits a control signal "Enq_status", which is a message for requesting information about the charging data (or the charging file) to be transmitted, to the CDSB 52, whereby the CDSB 52 The control signal "Enq_Ack", which is a message indicating information on the charging file to be transmitted, is transmitted to the charging center 70.

In addition, the charging center 70 receiving the control signal "Enq_Ack" transmits "Poll", which is a control signal for requesting the transmission of data regarding the charging data (or charging file) to be transmitted, to the CDSB 52.

Receiving the control signal "Poll", the CDSB 52 transmits the control signal "Header" indicating the header (HEADER) of the charging data (or charging file) to be transmitted to the charging center 70, and receives the received signal. The charging center 70 transmits the control signal " Header_Ack " to the CDSB 52, indicating that the header is normally received.

Thereafter, the CDSB 52 transmits the charging data to be transmitted to the charging center 70. The CDSB 52 transmits a control signal indicating that the charging center 70 has normally received the charging data. Will be sent).

In this case, when the billing data is to be sent in a billing file unit, the billing file is divided into records (RECORD) and sequentially transmitted. The billing center 70 receiving the billing data receives this record every time it receives each record. The control signal is transmitted. Fig. 5 shows the control flow when the charging data is bundled and transmitted in units of charging files.

For reference, it takes about 3 minutes to collect billing data and create a billing file. Therefore, when the billing data is transmitted as a billing file, the data is eventually transmitted every three minutes, thereby real-time billing data transmission.

This can achieve almost the same effect while greatly reducing the traffic (TRAFFIC) compared to transmitting each time the charging data is generated, since the difference of three minutes can be neglected in the actual operation, the data in the unit of the billing file Will be sent.

On the other hand, the CDSB 52, which has transmitted all the data for the charging data (or the charging file), transmits a control signal "Eot", which is a message indicating the end of the charging data, to the charging center 70, and responds thereto. By receiving the control signal "Eot Ack" which is a signal from the charging center 70, the transmission operation for one time is completed.

Accordingly, by repeatedly performing the above process, the charging data can be transmitted to the charging center 70 in real time (or in real time).

In the figure, the control signal " Record ", which is not described in the drawing, is a signal indicating the transmission of each record when the billing file is transmitted in the record unit in order to transmit the billing data in the unit of billing file, and the control signal " Record_Ack " This signal is generated when normal reception is received.

As described above, the "billing data control device of the mobile communication exchange" of the present invention, in particular, transfer the charging data as soon as the charging data generated through the network for the charging data transfer between the charging center and each exchange. As a result, first, there is an effect of enabling real-time billing data segmentation on the operator side, and second, billing data lost or damaged during transmission is retransmitted by the billing data retransmission function to improve reliability of billing data. Third, there is an effect of separately managing the transfer record of the billing data at the exchange, and then transferred to the billing center when requested by the operator, thereby ensuring the coincidence of the billing data between the exchange and the billing center.
