Abstract

PROBLEM TO BE SOLVED: To simplify processing and to shorten the total communication time by omitting data communication for a series of processes including the establishment of a data communication circuit, the transfer of the request data and the disconnection of a communication circuit when a data request is received. SOLUTION: The PHS data communication devices 11 and 23 to 25 receive the PHS signals and identify the PS call numbers of a transmitting station which are included in those PHS signals. Then only the transmission of PHS signals is executed when the PS call numbers are coincident with the transfer mode identification numbers corresponding to a data request mode, and the data communication is not executed. When the transfer mode identification numbers corresponding to an answer mode are identified, i. e., the received PHS signals are transmitted in a data answer mode, the PHS signals are transmitted and the data communication is also executed. Therefore, a series of processes including the establishment of a data communication circuit, the transfer of data and the disconnection of a communication circuit are not executed when a data request is received and then executed in the data answer mode. Thus, the processing is simplified when the data request is received.

PHS data communication device 2 and P
The PHS data communication device 3 and the PHS data communication device 4 are arranged so that radio waves can reach between them. The PHS data communication devices 1 to 4 have data terminals (DTE) 5 to 8
Is connected.

Here, for example, a process executed by each of the PHS data communication devices 1 to 4 when the data terminal 5 reads data (stored data) stored in the data terminal 8 will be described.

[0006] From the data terminal 5 to the PHS data communication device 1
When the data request signal is output to the PHS data communication device 1, the PHS data communication device 1 establishes a data communication line with the PHS data communication device 2 (see A in FIG. 12) and transmits the request data to the PHS data communication device.
The data is transmitted to the data communication device 2, and when the transmission of the request data is completed, the data communication line is disconnected.

Next, the PHS data communication device 2 to which the request data is given from the PHS data communication device 1
A data communication line is established with the data communication device 3 (see B in FIG. 12), the request data is transmitted to the PHS data communication device 3, and when the transmission of the request data is completed, the data communication line is disconnected. Then, the PHS data communication device 3 to which the request data has been given from the PHS data communication device 2,
A data communication line is established with the PHS data communication device 4 (see C in FIG. 12), and request data is transmitted to the PHS data communication device 4.

[0008] The PHS data communication device 4 to which the request data is given from the PHS data communication device 3 outputs a data request signal to the data terminal 8, and the data stored in the data terminal 8 from the data terminal 8 ( Upon input of the stored data, response data including the stored data is transmitted to the PHS data communication device 3.

By the way, in this case, as described above, data communication consisting of a series of processes such as establishment of a data communication line, transfer of data (request data and response data), and disconnection of the data communication line is performed by the adjacent PHS data communication. Each is performed between devices. This is because the direct communication (communication between slave units) between PHS data communication devices is an RCR.
This is because the multiplexing number is defined as 1 by the standard of STD-28 (standard name: second generation cordless telephone system (personal handy phone system)), that is, the PHS data communication device 1 and the PHS data communication device 3
PHS data communication device 2 cannot establish a data communication line between PHS data communication device 1 and PHS data communication device 3 at the same time.

[0014]

According to the first aspect of the present invention, the transfer control means sets any one of a plurality of transfer mode identification numbers as the PS calling number on the transmitting station side of the PHS signal and the PS calling number. The PHS signal in which the transmitting station side PS calling number and the PS calling number are set
The signal is transmitted on the dedicated cell channel by the HS signal transmitting means.

According to this method, when there are a data request mode and a data response mode as a plurality of transfer modes, the transmission station side PS call number of the PHS signal and the transfer mode identification corresponding to the data request mode as the PS call number. When the number is set, the PHS signal is transmitted in the data request mode. On the other hand, the transmission station side PS calling number of the PHS signal and the transfer mode identification number corresponding to the data response mode are set as the PS calling number. Then, the PHS signal is transmitted in the data response mode.

When the PHS signal is received on the dedicated cell channel by the PHS signal receiving means, the transmitting station PS calling number included in the received PHS signal is identified by the transmitting station PS calling number identifying means. At the same time, the PS call number included in the received PHS signal is identified by PS call number identification means. Then, the transfer control means performs a first transfer processing of transmitting the PHS signal on the dedicated cell channel by the PHS signal transmitting means based on the identification result by the transmitting station side PS calling number identification means, and transmitting the PHS signal to the PHS signal. Means for performing transmission on the individual cell channel and performing data communication by the data communication execution means, and selects and executes any of the transfer processing. And processing the received PHS signal based on the received PHS signal.

However, in this case, the received PH
The transmitting station side PS calling number included in the S signal is identified as a transfer mode identification number corresponding to the data request mode,
That is, if the received PHS signal is identified as being transmitted in the data request mode, the PHS signal is transmitted on the dedicated cell channel by the PHS signal transmitting means, while the received PHS signal is transmitted. If the transmitting station side PS calling number included in the signal is identified as the transfer mode identification number corresponding to the data response mode, that is, if the received PHS signal is identified as being transmitted in the data response mode , The PHS signal is transmitted by the PHS signal transmitting means on the dedicated cell channel, and the data communication is executed by the data communication executing means. When the PS calling number included in the received PHS signal is identified, the received PHS signal is processed based on the identification result.

As described above, according to the present invention, in the direct communication (communication between slave units) between PHS data communication apparatuses, the RCR
According to the standard of STD-28 (standard name: second generation cordless telephone system (personal handy phone system)), an individual cell channel is used as a control physical slot, and the transmission station side PS calling number is assigned to the individual cell channel. And the PS calling number is included. By identifying the transmitting station side PS calling number included in the dedicated cell channel, the received PH
Whether the S signal is transmitted in the data request mode, that is, whether it is a PHS signal corresponding to the data request, or whether it is transmitted in the data response mode, that is, the PHS signal corresponding to the data response Is to be identified.

When the PHS signal is identified as a PHS signal corresponding to the data request, the PHS signal is only transmitted on the dedicated cell channel, that is, the data communication is not performed, and the PHS signal is not transmitted. PHS
If it is determined that the signal is a signal, the PHS signal is transmitted on the dedicated cell channel and the data communication is performed.

Therefore, in this case, when a data request is made, data communication consisting of a series of processing of establishing a data communication line, transferring requested data, and disconnecting the data communication line is not executed. Then, at the time of data response, data communication consisting of a series of processing of establishing a data communication line, transferring response data, and disconnecting the data communication line is executed, that is, processing at the time of data request is performed. Since the simplification is achieved, the communication time as a whole can be reduced.

According to the second aspect of the present invention, the transfer control means determines that the PS calling number included in the received PHS signal is different from any of the plurality of transfer mode identification numbers set for itself. In some cases, the relay control is executed, and when it is determined that the PS calling number included in the received PHS signal is the same as one of the plurality of mode numbers set for the self, the incoming call control or the reply control is executed. I do.

According to this embodiment, the same operation and effect as those of the first aspect can be obtained, and the PH can be obtained.
Upon receiving the S signal, the relay control, the incoming call control, and the reply control can be efficiently executed, and the efficiency can be improved.

According to the third aspect of the invention, when operating the PHS data communication system, the overall communication time can be reduced.

Then, the transfer control unit 15 of the PHS data communication device 23 establishes a data communication line with the PHS data communication device 24 (step S9) (see E in FIG. 1). Since the stored data is stored in the data buffer 14 of 24,
The response data including the accumulated data is received from the PHS data communication device 24 (step S10), and stored in the data buffer 14. Then, when the reception of the response data is completed, the transfer control unit 15 of the PHS data communication device 23 disconnects the data communication line (Step S11).

Next, the transfer control unit 15 of the PHS data communication device 23 identifies the PS calling number included in the received PHS signal, and here, as the PS calling number, “10”
01 "is set, which is different from the own telephone number, so that" NO "is determined in the step S12,

Here, the PHS signal transmitted from the PHS data communication device 23 is, as described above, because the PHS data communication device 23 and the PHS data communication device 11 are arranged in a positional relationship where radio waves can reach. This is received by the PHS data communication device 11 (see f in FIG. 1).
That is, in this case, the transfer control unit 15 of the PHS data communication device 23 receives the PHS signal transmitted from the PHS data communication device 24, and converts the received PHS signal into a PHS signal.
The data is transmitted to the HS data communication device 11, that is, the transfer control unit 1 of the PHS data communication device 24 described above.
The relay control is executed in the same manner as in No. 5.

When the PHS data communication device 11 receives the PHS signal transmitted from the PHS data communication device 23, the transfer control unit 15 of the PHS data communication device 11
Goes out of the standby state, identifies the system call code included in the received PHS signal, and, when it determines that the system call code is the same, shifts to a transfer control process (see FIG. 7).

The transfer control unit 15 of the PHS data communication apparatus 11 that has shifted to the transfer control processing first receives the received PHS

Since the stored data is stored in the data buffer 14 of 23,
The response data including the stored data is received from the PHS data communication device 23 (step S10) and stored in the data buffer 14. Then, when the reception of the response data is completed, the transfer control unit 15 of the PHS data communication device 11 disconnects the data communication line (step S11).

Next, the transfer control unit 15 of the PHS data communication device 11 identifies the PS calling number included in the received PHS signal, and here, as the PS calling number, “10”
01 "has been set and matches its own telephone number, so" YES "is determined in the step S12, and the process shifts to the step S14. Then, the transfer control unit 15 of the PHS data communication device 11 extracts the accumulated data from the response data stored in the data buffer 14, and outputs the accumulated data to the data terminal 17 (Step S14)

After the transfer process in the request mode is executed and the transfer process in the data response mode is executed accordingly, the transfer process in the data confirmation mode is executed as shown in FIG. 9 (FIG. 9). 9, g, h,
i). With such a configuration, it is possible to determine whether or not the transfer processing in the data response mode, that is, the transfer of the response data has been successfully performed.

In this case, when the transfer processing in the data confirmation mode is performed, the transfer processing in the data request mode is performed in the same manner as in the case where the transfer processing in the data request mode is performed.
Data communication consisting of a series of processes of establishing a data communication line, transmitting data, and disconnecting the data communication line is not executed.

Further, the PHS data communication device 11
As shown in FIG. 10, the PHS data communication devices 23 to 25 may have, as necessary, a telephone number corresponding to the data request mode, a telephone number corresponding to the data response mode, and a telephone number corresponding to the data confirmation mode. In addition to telephone numbers corresponding to the three transfer modes for numbers, telephone numbers corresponding to the data notification mode can be set.

That is, the PHS data communication apparatus 11 can set a telephone number in the data request mode: 0001 a telephone number in the data response mode: 1001 a telephone number in the data confirmation mode: 2001, and a telephone number: 3001 in the data notification mode. Has become.

In the PHS data communication device 23, a telephone number in the data request mode: 0002 a telephone number in the data response mode: 1002 a telephone number in the data confirmation mode: 2002 a telephone number in the data notification mode: 3002 Has become.

In the PHS data communication device 24, a telephone number in the data request mode: 0003 a telephone number in the data response mode: 1003 a telephone number in the data confirmation mode: 2003, and a telephone number: 3003 in the data notification mode can be set. Has become.

Further, in the PHS data communication device 25, a telephone number in the data request mode: 0004 a telephone number in the data response mode: 1004 a telephone number in the data confirmation mode: 2004 and a telephone number in the data notification mode: 3004 Has become.

By setting the telephone numbers in the data notification mode in the PHS data communication device 11 and the PHS data communication devices 23 to 25 in this way, the data communication between the PHS data communication devices is performed as described above. In addition to the transfer processing in the request mode, the data response mode, and the data confirmation mode, the transfer processing in the data notification mode is executed as shown in FIG. 11 (see j, k, l in FIG. 11). ). With such a configuration, it is possible to execute transmission of the notification data.

In this case, when the transfer processing in the data notification mode is performed, the transfer processing in the data response mode is performed in the same manner as described above.
Data communication consisting of a series of processes of establishing a data communication line, transmitting data, and disconnecting the data communication line is executed (see J, K, and L in FIG. 11).

By the way, each transfer control unit 1 of the PHS data communication device 11 and the PHS data communication devices 23 to 25
In No. 5, a reception condition is set, and only when the reception condition is satisfied, a PHS signal transmitted from another PHS data communication device is received.

As described above, the PHS signal 25 transmitted from the PHS data communication device 23 in the data request mode is, for example, a PHS data communication device This is because the PHS data communication device 11 may also receive the data at the same time as the data is received by the PHS data communication device 24. If the data is received by the PHS data communication device 11, useless processing is executed.

Therefore, in this case, as a receiving condition, for example, the PHS transmitted from the PHS data communication device having a telephone number smaller than the own device in the data request mode is used.
For the HS signal, the reception of the PHS signal is permitted,
For a PHS signal transmitted in a data request mode from a PHS data communication device having a telephone number greater than its own, reception of the PHS signal is prohibited, and a PHS data communication device having a telephone number greater than its own is transmitted in a data response mode. For a transmitted PHS signal, reception of the PHS signal is permitted, and for a PHS signal transmitted in a data response mode from a PHS data communication device having a telephone number smaller than its own, reception of the PHS signal is prohibited.

In other words, when the received PHS signal is identified as being transmitted in the data request mode, only the transmission of the PHS signal is performed, and no data communication is performed. When the transmitting station side PS calling number is identified as the transfer mode identification number corresponding to the data response mode,
That is, when it is determined that the received PHS signal was transmitted in the data response mode,
A signal is transmitted and data communication is performed.

Therefore, when a data request is made, a data communication consisting of a series of processes of establishing a data communication line, transferring requested data, and disconnecting the data communication line is not executed. The data communication consisting of a series of processes of establishing a data communication line, transferring response data, and disconnecting the data communication line is executed, that is, processing at the time of a data request is simplified. Therefore, the communication time as a whole can be reduced.
