When a connection completion signal is received after receiving a connection response signal, a data delivery acknowledgment signal indicating that transmission data has been successfully transmitted to the receiving terminal is created, and when a connection non-response signal is received, the transmission data is transmitted to the receiving terminal. A data acknowledgment signal indicating that the transmission was not successful is created. This acknowledgment signal is transmitted to the mobile data terminal by a transmission / reception procedure in the mobile communication system.

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

FIG. 1 is a system configuration diagram showing an embodiment of the present invention. In FIG. 1, a mobile communication system (radio communication system 1) of the present embodiment includes a mobile radio switching network 10 including a mobile radio switch 11 (plurality) and a mobile radio switching network 11
And a plurality of mobile data terminals 13 that can move freely within the service area and communicate with the corresponding wireless base station 12 by radio wirelessly. Have.

The mobile radio exchange 11 is a wired public telecommunications network 21 such as a telephone public network or a data public network for connecting a facsimile terminal 22, a personal computer terminal 23 and a telephone 24.
(Wired communication system 2) and the mobile data terminal 1
3 enables communication with the facsimile terminal 22, the personal computer terminal 23, and the telephone 24.

FIG. 2 is a block diagram showing the internal configuration of the mobile radio exchange 11. In FIG. 2, the mobile radio switch 1
Reference numeral 1 denotes an interface circuit (CIF) 111 for a wired public telecommunication network, a data transmission / reception control circuit (DCNT) 112 including actual data exchange control, a signal control circuit (SCNT) 113 for controlling response signals and the like. And a radio interface circuit (RIF) 114 that aligns control signals and data with mobile data terminals and includes an interface circuit with a radio base station.

Next, FIG. 3 to FIG. 9 together with FIG. 1 and FIG.
The operation will be described with reference to FIG.

FIG. 3 shows a connection sequence between the mobile data terminal 13 and the mobile radio exchange 11 when making a call.

When data is transmitted from the mobile data terminal 13 to the facsimile terminal 22 or the telephone 24 connected to the wired public telecommunication network 21 (telephone public network, data public network), the originating mobile terminal number, incoming call The mobile data terminal 13 transmits from the mobile data terminal 13 the model data indicating the type of the facsimile, telephone, etc., and the call setting number information including the telephone number of the called side, and after receiving a response signal from the mobile radio exchange 11, transmits the data. Start.

After receiving the final data included in the data, the mobile radio exchange 11 returns a response to the mobile data terminal 13,
Notifies that all data has been received normally. After this,
The communication between the mobile wireless switchboard 11 and the wired public telecommunications network 21 is taken over.

FIG. 4 shows a wired public telecommunications network 21
FIG. 5 shows a connection sequence with the mobile wireless switching system 11 when the NS (registered trademark) net service is selected.

From the mobile data terminal 13 to the mobile radio switch 1
When the communication to mobile station 1 is completed, an off-hook signal and a dial signal (call setting number information) are transmitted from mobile radio exchange 11 to wired public telecommunication network 21, and whether or not the signal can be connected by wired public telecommunication network 21 is determined. Check
If there is no problem with the connectivity, a call setting acceptance signal is returned to the mobile wireless switching system 11.

Thereafter, a call signal is transmitted to the facsimile terminal 22 or the telephone 24 on the receiving side, and a response signal is transmitted to the mobile radio switch 11 in response to a response from the receiving side.

If the receiving side cannot respond due to absence or the like, a no-response signal is transmitted from the wired public telecommunications network 21 to the mobile radio exchange 11 side. At this point, the mobile radio switch 11 makes a call to the mobile data terminal 13 and transmits a transmission result data including a non-response signal as a data delivery acknowledgment signal indicating that the data could not be normally transmitted to the other party. (See FIG. 7).

When receiving the non-response signal, the mobile data terminal 13 displays a message indicating that transmission was not possible and makes the sender perceive it (see FIGS. 8B and 8D). This allows the sender to take measures such as retransmission.

When the mobile radio exchange 11 receives a normal response signal to the calling signal, it shifts to the next data communication and disconnects after receiving the final data on the receiving side, so that a disconnection signal is sent from the wired public telecommunication network 21. The message is transmitted to the mobile wireless exchange 11, and it can be confirmed that the transmission was successful. Upon receiving the disconnection signal, the mobile radio exchange 11 calls the mobile data terminal 13 and includes a completion signal in the transmission result data as a data delivery confirmation signal indicating that the data has been successfully transmitted to the other party. (See FIG. 7).

When receiving the completion signal, the mobile data terminal 13 displays a message indicating that the transmission has been normally completed, and makes the sender sense (see FIGS. 8A and 8C).

FIGS. 5 and 6 show a connection sequence with a telephone service as the wired public telecommunications network 21, respectively.
4 shows a connection sequence with a DX-P service. Since the connection sequence of the INS net service and the sequence of receiving the response signal and the completion signal shown in FIG. 4 are almost the same, the description is omitted.

FIG. 9 shows a facsimile terminal which is called from the mobile data terminal 13 and which is connected to the wired public telecommunication network 21 through the mobile radio exchange 11, as shown in the sequence diagram of FIGS. Mobile data exchange 13 and mobile wireless exchange 1 when data is transmitted to a called terminal such as 22
1 shows each operation as a flowchart.
