BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data transmission apparatus of a personal communication exchange (PCX) and, more particularly, to a data transmission apparatus of a personal mobile communication exchange for transmitting data using an SS No. 7 layer .

In general, a data transmission system using No. 7 layer in an exchange is referred to as a common channel signaling system in the sense of exchanging signals for a plurality of channels as one common channel.

That is, the data transmission method using the No. 7 layer can be regarded as a kind of data communication characterized by various signals and information transmission between processors existing in a communication network.

This signaling method can be used as a call control signal for communication services such as telephone, ISDN, circuit switched data transmission, or various types of information delivery means in a special center (for management and maintenance) and exchange period in the communication network.

FIG. 1 is a block diagram of a typical personal mobile communication exchange. As shown in the figure, a first exchange 20 and a second exchange 20 30 or a home location register (HLR) 40, which is a database storing overall data for the first exchange 20 and all mobile communication subscribers.

For example, in the case of a location registration request, that is, when the location of the subscriber terminal 10 is changed from the first exchange 20 to the second exchange 30, the current location is changed to the second exchange 30, The data of the subscriber terminal 10 belonging to the first exchange 20 must be transferred to the terminal of the second exchange 30.

That is, when location registration is requested from the operator terminal 10, the first exchange 20 exchanges data stored in a VLR (not shown) connected to the first exchange 20 (data copied from the HLR 40 and stored The second exchange 30 needs to copy the data stored in the HLR 40 again and store the copied data in the VLR connected to the second exchange 30. In order to perform the process as described above, As shown in the figure, the data transmission method using No. 7 layer should be used.

2 is a block diagram of a general SS No. 7 hierarchical structure. At this time, the role of a Mobile Application Part (MAP) 210 is determined from an application process (AP) When a registration request is received, the message is replaced with a TCAP (Transaction Capability, 220) message. In addition, the TCAP 220 combines the messages exchanged between the TCAP 220 and the MAP 210 into one message, and the SCCP 230 / MTP 240, which is a lower layer thereof, And sends the generated message to the other party.

At this time, the MAP 210 should establish a dialogue for performing location registration required in the application process 200, that is, a path for transmitting data.

FIG. 3 is a block diagram of a data transmission apparatus of a personal mobile communication exchange according to the related art. When a location request is requested from the application process 200, for example, a local MAP 210, The Dialogue Map Service State Machine (DSM) 211 establishes a dialog for transmitting the location registration request message, and then transmits a location registration request message of the application process 200 to the TCAP And the encoding unit (RSM: Requesting Service State Machine) 212 encodes data accompanying the location registration request. At this time, the SCCP and the MTP, which are the lower layers of the TCAP, transmit the message created by the above-described procedure to the remote station, that is, the partner station.

Accordingly, the remote TCAP 320 receives the location registration request message from the lower layer and transmits the location registration request message to the MAP 310. Accordingly, the dialog setting unit 311 of the MAP 310 establishes a path for receiving the location registration request message, and the PSM 312 decodes the encoded and transmitted data, (300).

At this time, the dialog setting units 211 and 311 form each time a subscriber's request is performed. Thus, after one or two processes are created per dialogue to establish a dialogue, it maintains an idle state until a message for the subscriber's request is received and a response is received from the counterparty (remote) The occupation area of the memory is increased and the performance of the system is deteriorated. Therefore, although not shown in the drawing, there is a problem that there is a load process for controlling the overall load.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a method and apparatus for transmitting data corresponding to a request of a mobile communication subscriber by storing state information of a dialogue in a single process And to prevent a dialog corresponding to each mobile communication subscriber request from being set separately, thereby reducing the number of processes generated.

According to an aspect of the present invention, there is provided a data transfer apparatus for a personal mobile communication exchange for transferring data using an ES No. 7 hierarchy, comprising: an application process for receiving and transmitting each request for a mobile communication subscriber; (AP); A request for the mobile communication subscriber and a request for the mobile communication subscriber to be transmitted to the mobile communication subscriber, A mobile communication application process (MAP) each performing; And a message transmission unit for transmitting data corresponding to each request of the mobile communication subscriber received in the mobile communication application process and receiving response data corresponding to the transmitted data and transmitting the response data to the mobile communication application process.

Other objects and various advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 4 is a block diagram of an apparatus for transmitting data using the SS No. 7 layer in the personal mobile communication exchange according to the present invention. The application process layer 400, the dialog setting unit 411, A mobile communication application sublayer 410 including a storage unit 412, a decoding unit 413 and an encoding unit 414, a TCAP (Call Processing Function) sublayer, and a signal connection control unit (SCCP) And a message delivery sublayer (MTP) 420.

The application process layer 400 shown in the figure is configured to receive each request of the mobile communication subscriber and to transmit the received request to the mobile communication application sublayer (MAP) 410.

At this time, the mobile communication application sublayer (410, MAP) stores the status information of the data transmission line for transmitting each request of the mobile communication subscriber transmitted from the application process layer (400) .

That is, the dialogue setting unit (DSM) 411 establishes a data transmission line dialog for performing each request of the mobile communication subscriber transmitted from the application process layer 400. Accordingly, the dialog setting unit 411 transmits the data corresponding to each of the requests of the mobile communication subscriber to the encoding unit 414, and, as will be described later, And transmits the data to the decrypting unit 413. The decrypting unit 413 decrypts the received data.

At this time, the dialog setting unit 411 determines whether or not the status information of the dialog stored in the storage unit 412, that is, whether or not the setting of the dialog is completed and whether the data responding to each request of the mobile communication subscriber, And the application process layer 400 performs the respective requests of the mobile communication subscriber to read data from the storage unit 412, which is a database in which the data is stored.

Meanwhile, the RSM 414 encodes data corresponding to each request of the mobile communication subscriber transmitted through the set dialog, and encodes the message corresponding to the message transmission sublayer 420 (the TCAP layer of the es number seven layer, SCCP layer and MTP layer), and the message delivery sublayer 420 transmits the message to the message delivery sublayer of the correspondent partner.

At this time, the message delivery sublayer 420 transmits the data to the dialog setting unit 411 when receiving data responding to each of the mobile communication subscriber requests transmitted from the counterparty. Accordingly, the dialogue setting unit 411 receives data responding to each mobile communication subscriber request, and transmits data corresponding to each of the received mobile communication subscriber requests to the PSM 413.

Accordingly, the decryption unit 413 decrypts data corresponding to each of the received mobile communication subscriber requests and transmits the decrypted data to the application process layer 400. [

As described above, the data transmission apparatus of the personal mobile communication exchange according to the present invention includes a mobile communication application sublayer (MAP) including one process generated at the time of initial setting of a dialogue and a storage unit for storing status information of a dialogue And transmits data corresponding to each request of the mobile communication subscriber, thereby reducing the number of processes corresponding to each mobile communication subscriber request.
