First, the operation of the present invention will be described according to the case of FIG.

This is an operation in which the mobile subscriber requests a connection from the public subscriber.

In the first personal computer 10 of FIG. 1, an outgoing signal is transmitted to the base station control and switching system 40 by providing a mobile telephone subscriber with an AT command for asynchronous mobile data communication, and then the base station control and switching system 40. After confirming whether the voice communication or asynchronous mobile data communication, and sets the mobile data by sending and receiving a signal message with the mobile data communication control system 50.

That is, the mobile data access connection management unit 55a of the main processing unit 55 managing the mobile data access device 51 of the mobile data communication control system 50 receives the mobile telephone subscriber from the base station control and exchange system 40. Confirms that the asynchronous mobile data communication is to be performed, and provides a modem connection request message to the B-channel managing unit 55b of the main processing unit 55. Accordingly, the B channel manager 55b allocates idle modem resources and transmits a modem connection request message to the modem manager 55c. The modem manager 55c then sends a modem initialization command message to the data processing apparatus 53 of the mobile data communication control system 50.

The main control part 53a of the data processing apparatus 53 which received this confirms the occupation of idle modem resources, and sets a modem basic configuration value. Then, according to the processing result thereof, the modem initialization result message is provided to the modem management unit 55c of the main processing device 55 including the success or failure and the cause thereof. The modem manager 55c provides the modem initialization result message to the B channel manager 55b as a modem connection response message. At this time, according to the result reported above, the B channel management unit 55b performs a procedure for providing a B channel connection request message to the data processing apparatus 53 and the subsequent procedure.

That is, if the modem connection fails, the modem terminates after sending the modem connection response without proceeding with the B channel connection request. When the modem connection is made by the successful modem initialization of the data processing apparatus 53, the B channel management unit 55b processes the data. The device 53 transmits a B channel connection request message and receives a B channel connection response message in response.

Upon receiving this, the B channel manager 55b provides a modem connection response message to the connection manager 55a as mobile data, and the connection manager 55a as mobile data is one B channel to the mobile data and the data processing device 53. One highway timeslot of the B channel port of the B channel processing unit 53b allocated by the main control unit 53a of the " That is, a time slot of the connection device 51 and the B channel processing unit 53b is connected to the mobile data through the switching device 54.

At this time, the B-channel management unit 55b transmits the connection request message to the public network data to the modem management unit 55c before the switching operation, and transmits the connection request message to the public network data from the modem management unit 55c to the connection management unit 55d. To be delivered.

During this process, the data processing apparatus 53 configures the user modem environment using the previously set B channel, and when this is completed, the data processing apparatus 53 completes the user request configuration completion message to the modem manager 55c. to provide.

Subsequently, when the modem manager 55c, which has been waiting for input of the connection response message from the public network data from the public network data manager 55d, receives this message from the public network side, the modem manager 55c is assigned to the public network data. It switches one channel and one highway timeslot of the assigned modem port of the data processing device 53. That is, a time slot of the connection device 52 and the modem processing unit 53c is connected to the public network data through the switching device 54.

When the switching process is completed, the modem manager 55c provides an ATD command transmission request message to the data processing apparatus 53.

Upon receiving this message, the data processing apparatus 53 provides the ATD command to the modem processing unit 53c, and then the modem processing unit 53c waits for carrier detection for a predetermined time. At this time, when the carrier in the air is detected or a predetermined time elapses, an inter-modem link setting confirmation message is provided to the modem manager 55c of the main processing apparatus 55. The inter-modem link setting confirmation message includes information on the success or failure of carrier detection of the data processing apparatus 53.

Accordingly, the modem manager 55c provides a B channel manager 55b with a modem connection confirmation message for connection between the modem of the subscriber of the public network and the modem of the mobile data communication control system 50, and the B channel manager 55b. By providing a connection message between modems to the connection management unit 55a as mobile data, the mobile phone subscriber can perform asynchronous mobile data communication with the personal computer of the public network subscriber.

On the other hand, referring to the flow between the main processing unit 55 and the data processing unit 53 in the present invention when incoming by the public network subscriber according to Figure 5, the process is similar to Figure 4 but the modem of the main processing unit 55 The operation in which the message transmission and reception between the management unit 55c and the connection management unit 55d through the public network data is reversed is different. The corresponding messages are connection request message with public network data and connection response message with public network data.

In this case, the connection request message is unnecessary by the public network data between the B channel management unit 55b and the modem management unit 55c. Then, the data processing apparatus 53 informs the modem management unit 55c of the user request environment configuration end message, and provides the modem management unit 55c to the data processing apparatus 53 for the ATA (AT Answer) command transmission request message. This is different from the case of origination.

6 is a flow chart between the main processing device 55 and the data processing device 53 at the time of user source recovery in accordance with the asynchronous mobile data communication release request when the user source recovery is performed in the present invention.

There are two cases of this process, the first of which is performed as in FIG. 6A. That is, when the connection release request message is received from the mobile data side, when the connection management unit 55a provides the modem connection release request message to the B channel management unit 55b as the mobile data of the main processing unit 55, the B channel management unit ( 55b) provides a modem connection disconnection request message to the modem manager 55c, and at the same time, provides a B channel disconnection command message to the data processing apparatus 53 side. The modem manager 55c provides a modem disconnection command message to the data processing apparatus 53 side. Receiving this, the data processing apparatus 53 initializes the used modem and the B channel state, and provides the modem connection release confirmation message and the B channel connection release confirmation message to the modem manager 55c and the B channel manager 55b, respectively. Thereafter, the modem manager 55c provides a release request message to the public network data to the connection manager 55d as the public network data and releases the switching.

In the second case, as shown in FIG. 6B, the connection management unit 55d with the public network data provides the release request message with the public network data to the modem manager 55c. The subsequent procedure is similar to the operation shown in FIG. 6A, but in the last step, the data processing apparatus 53 provides the B channel disconnection confirmation message, and then provides a modem disconnection release message to the connection management unit 55a as mobile data. The operation of releasing the switching in the connection management unit 55a with movement data is different.

As described above, according to the present invention, unlike the conventional wired network, the asynchronous mobile data communication with the public network subscriber is possible without a modem installed in the computer of the mobile telephone subscriber subscribed to the CDMA mobile communication network. It is very economical because the cost of receiving data communication service is low, and it is very effective to provide a wide range of services to mobile subscribers.
