DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless communication network system suitable for mobile data communication for performing data communication via a mobile communication network using a wireless communication line for a portable telephone or the like.

[0002]

2. Description of the Related Art A mobile communication network using a radio communication line such as an electromagnetic wave for a portable telephone, a car telephone, or the like has been widely used, and is being used not only for ordinary telephone calls but also for data communication.

In conventional data communication using a mobile communication network, a transmitting / receiving terminal is directly connected to a switching line, a transmitting terminal transmits data, and a receiving terminal receives the data at the same time. . Also, the communication partner is limited to one location designated by the telephone number, and is a one-to-one fixed communication.

In a mobile phone or the like, information such as position information is transmitted from a mobile phone as a communication device to a wireless base station even when communication is not being performed, but no information on data communication is transmitted.

In data communication, a series of data often needs to maintain continuity. For this reason, if the line is disconnected during the data transfer due to deterioration of the wireless line condition or the like, the data transfer is often restarted from the beginning. Further, even when the power of the terminal on the receiving side is turned off or when the receiving side is in a place where radio waves cannot reach, connection is attempted, so the receiving terminal needs to be always in a standby state.

[0006] A digital mobile phone has a telephone number supplementary service dedicated to data communication, and identifies whether the phone itself sounds a ringing tone or connects to a terminal. Even in such a case, in data communication, the other party is specified by a specific telephone number, and one-to-one simultaneous transmission and reception is performed.

[0007]

As described above, in the data communication using the conventional mobile communication network, the transmitting and receiving terminals are directly connected via a switching line, and the transmitting and receiving terminals receive the data simultaneously with the data transmission from the transmitting terminal. This is a one-to-one fixed communication in which data reception is performed by the terminal on the side, and the communication partner is limited to one location specified by the telephone number. In a mobile phone or the like, information such as position information is constantly transmitted to a wireless base station other than during a call, but no information regarding data communication is transmitted.

Further, in data communication, it is often necessary to maintain continuity of a series of data, and data transfer is performed even when a line is disconnected due to deterioration of a wireless line condition during data transfer. You have to start over. For this reason, the time required for data communication on both the transmitting and receiving sides increases, and the communication cost increases.

[0009] Further, even when the terminal or the like is turned off or in a place where radio waves do not reach, or when reception on the receiving side is impossible, connection is attempted, so that there is much waste on the transmitting side. In addition, it is necessary to keep the receiving terminal or the like in a standby state at all times, and wasteful consumption of radio wave resources and power resources such as a battery is large.

[0010] In a digital mobile phone, there is already a telephone number addition service dedicated to data communication. However, it merely identifies whether the telephone itself sounds a ringing tone or connects to a terminal.

In addition, since one-to-one simultaneous transmission / reception is performed by designating the other party with a specific telephone number, the sender / receiver is forced to operate at the same time. To send the same data to a plurality of recipients, the sender needs to communicate the same number of times as the number of recipients. Further, unspecified recipients could not receive the data upon request.

The present invention has been made in view of the above circumstances, and in a communication network using a wireless line, transmission data is temporarily stored in a switching line, thereby enabling highly efficient data communication. It is an object of the present invention to provide a wireless communication network system that can effectively utilize terminal resources and radio wave resources and does not restrict the operation time of a transmitter / receiver.

You.

The second transmitting device 2 includes a second transmitting-side communication device 21 and a second transmitting terminal 22. The second transmission-side communication device 21 is a movable communication device such as a mobile phone for connecting to the mobile communication network 6, and the second transmission-side communication device 21 includes a second transmission terminal. 22 can be combined. The second transmitting terminal 22 receives P
C, a data communication terminal such as a workstation,
For example, it is connected to the communication device 21 via an appropriate communication interface such as a serial interface.

The receiving device 9 includes a receiving communication device 91 and a receiving terminal 92. The receiving-side communication device 91 is a mobile communication device such as a mobile phone for connecting to the mobile communication network 6 like the second transmitting-side communication device 21. Can couple the receiving terminal 92. The receiving terminal 92 is a data communication terminal such as a PC or a workstation, like the second transmitting terminal 22, and is connected to the communication device 91 via a communication interface such as a serial interface.

Here, it is assumed that data communication is performed from either one of the first transmitting device 1 and the second transmitting device 2 to the receiving device 9. However, the first transmitting device 1, the second transmitting device 2, and the receiving device 9
This configuration can perform both transmission and reception, and can perform data communication by reversing the transmission side and the reception side, or perform data communication between the transmission sides.

The public communication network 3 is a communication network that provides a switched line using a normal public telephone line, and is coupled to communication devices such as individual modems and telephones, for example, the communication device 11 of the first transmission device 1. . The public communication network 3 is connected to a mobile communication network 6 to enable mutual communication with a mobile phone or the like.

The radio base stations 4 and 5 are communication stations for coupling the mobile communication devices 21 and 91 and the like to the mobile communication network 6 by radio waves or the like, respectively. The radio base stations 4 and 5 are appropriately distributed in the service area of the mobile communication network, and the mobile communication devices 21 and 9 are provided.
Signals are transmitted and received wirelessly to and from the mobile communication network 6 with the mobile communication network 6.

The mobile communication network 6 is a communication network for providing a switching line using a mobile radio communication line, and is connected to the radio base stations 4 and 5 by wire or radio (for example, a microwave line). . The mobile communication network 6 is connected to the public communication network 3 as described above in order to enable mutual communication with devices connected to a normal public telephone line.

The data storage server 7 is provided in the mobile communication network 6, and temporarily stores transmission data from the transmission side when data communication is performed. If the designated receiving device, for example, the receiving device 9 can receive, the data storage server 7 immediately transfers the stored transmission data to the receiving device 9. The receiving device 9 coupled to the mobile communication network 6 via the wireless base station 5 does not use a line (that is, is not in a call), and the receiving terminal 92 is connected to the receiving communication device 91. It is possible to receive transmission data only when these power supplies are turned on and the receiving-side communication device 91 is located within the receivable area. If the data receiving server 7 cannot receive the specified receiving device 9,
The state of the receiving device 9 is monitored by the receiving device monitoring server 8, and when the receiving device 9 is ready to receive, the transmission data stored in advance is transferred to the receiving device 9.

In this system, the data storage server 7
For example, when receiving transmission data from the transmission side and storing the transmission data, the line with the transmission side is temporarily disconnected, and the transmission side is completed when the transmission of the stored transmission data to the reception side is completed. Call to notify the completion of data transfer. Once the transmission data is stored, if the receiving side cannot receive and transfer it to the receiving side within a predetermined time set in advance, it notifies the transmitting side to that effect and notifies the stored data. Discard.

The receiving device monitoring server 8 stores the transmission data from the transmitting side in the data storage server 7 and, when the line to the transmitting side is disconnected, when the designated receiving device 9 cannot receive the data. It functions and monitors whether the receiving device 9 is in a receivable state. That is, the receiving device monitoring server 8 determines that the receiving terminal 92 is not connected to the receiving communication device 91 of the receiving device 9 because the line of the receiving device 9 coupled to the mobile communication network 6 via the wireless base station 5 is not in use. It is connected and turned on, and monitors whether or not the receiving-side communication device 91 is located within the receivable area, that is, whether or not transmission data can be received. Upon detecting the receivable state of the receiving device 9, the receiving device monitoring server 8 controls the data storage server 7, calls the receiving device 9, and transmits the transmission data stored in the data storage server 7 to the receiving device 9. To transfer.

The data storage server 7 and the receiving apparatus monitoring server 8 may be connected to the mobile communication network 6 as shown in FIG. 1, but are incorporated in, for example, an exchange in the mobile communication network 6. Is also good.

Next, a specific operation in the wireless communication network system shown in FIG. 1 will be specifically described with reference to FIGS. FIG. 2 shows a basic operation in the case of a normal call instead of the data communication. In this case, a telephone number for a telephone call and a telephone number for a data communication are set on the receiving side, and it is assumed that a normal telephone call or a data communication is distinguished by the designated destination telephone number.

First, the transmitting communication device 11 or 21 of the transmitting device 1 or 2 calls, for example, a telephone number for communication of the receiving communication device 91 of the receiving device 9 (step S0).
1). In the case of a call from the transmission side communication device 11 of the transmission device 1, when a call is given to the public communication network 3, the reception device 9 is transmitted from the radio base station 5 via the mobile communication network 6 according to the destination telephone number. Is called (step S02). If the call is from the transmitting side communication device 21 of the transmitting device 2, in step S02, when a call is given to the mobile communication network 6 via the radio base station 4, the radio base station is set in accordance with the destination telephone number. 5, the receiving-side communication device 91 of the receiving device 9 is called.

In this case, since the call is a normal call, if the line is not used and only the receiving communication device 91 of the receiving device 9 is turned on and located in the communicable area, the reception is performed. If the receiving-side communication device 91 is capable of receiving, the line is immediately connected (step S0).
3) A call is made (step S04). Step S
After the call by the call 04 is completed, the line is disconnected (step S05), and the process for the call is completed.

In step S02, if the called receiving terminal is not receivable, a busy tone or a message to that effect is returned to the transmitting side, the line is disconnected, and the process is terminated.

FIG. 3 shows a process for data communication. First, the transmission terminal transmission phase from when the transmission terminal 12 or 22 of the transmission device 1 or 2 stores data in the data storage server 7 of the mobile communication network 6 will be described.

As the transmission terminal 12, the transmission-side communication device 11, and its communication line, general-purpose ones for ordinary public lines are used. The transmitting terminal 22, the transmitting-side communication device 21, and its communication line are a wireless terminal system in which the transmitting device 2 is connected to the mobile communication network 6. The transmitting side may be any of these transmitting devices 1 and 2. As described above, the receiving-side communication device 91 is provided with a telephone number for data communication in addition to a normal telephone number for a telephone call. In the case of a call to a telephone number for a call, connection to the receiving communication device 91 is immediately made, but a call to a data communication number is made (step S1).
In the case of 1), first, it is connected to the data storage server 7 of the mobile communication network 6 (step S12). Then, the transfer destination telephone number and the transfer data are transferred from the transmission terminal 12 or 22 to the data storage server 7, and these are stored (step S13). The line to the transmission device 1 or 2 is disconnected (step S14).

Next, the receiving terminal receiving phase, that is, data transfer from the data storage server 7 to the receiving terminal 92 will be described. When the data storage is completed, it is confirmed whether or not the transfer destination receiving device 9 can receive the data (step S1).
5). As described above, the receivable state in this case means that the line of the transfer destination receiving device 9 is not in use, the receiving communication device 91 and the receiving terminal 92 are connected, and their power is turned on. In addition, it means that the communication device 91 exists in the communicable area. In step S15,
If it is determined that the receiving device 9 is in the receivable state,
Immediately calls the receiving terminal 92 (step S16),
The line between the data storage server 7 and the receiving terminal 92 is connected (step S17), and the transmission data is transferred to the receiving terminal 92 (step S18).

If the transfer is interrupted due to a line trouble or the like during the data transfer in step S18 (step S1
9) Return to step S16 to automatically reconnect and transfer the untransferred portion. When the transfer of the transmission data is completed, the line between the data storage server 7 and the receiving terminal 92 is disconnected (step S20).

When the transfer is completed, the data storage server 7 calls the transmission terminal 12 or 22 (step S).
21) Connect the line (step S22), and
A transmission completion notification message is transmitted to 2 or 22 (step S23). When the transmission of the transmission completion notification in step S23 ends, the data in the data storage server 7 is deleted (step S25), and the process ends.

If it is determined in step S15 that the receiving apparatus is not in the receivable state, the receiving apparatus monitoring server 8 monitors the receiving apparatus 9 and waits for the receiving apparatus to enter the receivable state (step S26). Then, if there is no connection request from the receiving terminal (step S27) (step S28), the process proceeds to step S16 to call the receiving terminal 92, connect as described above, and transfer the transmission data. When a connection request is made from the receiving terminal 92 in step S28, the presence or absence of stored data in the data storage server 7 is confirmed in response to the call from the receiving terminal 92 (step S29) (step S3).
0) If there is data, the process proceeds to step S17 to perform data transfer. If it is determined in step S30 that there is no stored data, the line is disconnected (step S31), and the process ends.

If the receiving device 9 does not enter the receivable state after a predetermined time elapses (step S32), the transmitting terminal 12 or 22 is called (step S33), and the line is connected (step S33). (Step S34), the transmission terminal 12 or 22 transmits a transmission-incomplete, that is, a transmission-unavailable notification message (step S35). When the transmission of the transmission disable notification in step S35 is completed, the data in the data storage server 7 is deleted (step S3).
7), the process ends.

The data storage server 7 stores transmission data in a format as shown in FIG. 4, for example, for each unit record (R1). That is, the data stored in the data storage server 7 is, for each unit record (R1),
Reference number (# 1), transmission request time (# 2), destination telephone number (# 3), destination type (# 4), transmission result (# 5),
The transmission notification result (# 6) and the transmission data (# 7) are stored.

The destination type (# 4) is information indicating a specific destination, a group destination, or an unspecified destination. The transmission result (# 5) is information indicating whether the apparatus is in a standby state, transmitting, transmitting successfully, or transmitting unsuccessfully. Transmission notification result (#
6) is information indicating whether a transmission notification indicating transmission completion or transmission impossibility has not been transmitted or has been transmitted to the transmitting side.

The receiving device monitoring server 8 stores monitoring data in a format as shown in FIG. 5, for example, for each unit record (R2). That is, the data stored in the receiving device monitoring server 8 includes, for each unit record (R2), the communication device identification number (# 1), the communicable state (#
2), a receivable state (# 3), and the number of transmission request data (# 4) are stored.

The communication device identification number (# 1) is information such as a telephone number for identifying the communication device. The communicable state (# 2) is information indicating whether communication is possible or not. The receivable state (# 3) is information indicating whether receivable or unreceivable. The transmission request data number (# 4) indicates the number of transmission request data, and is information indicating 0 when there is no transmission request data and indicating the number (1 or more) when there is.

In step S13 of FIG. 3, the record R1 of FIG.
5 as well as one record at a time
Is incremented by one. In steps S15 and S27, the reception enabled state # 3 of FIG. 5 (and the communication enabled state # 2 as necessary) is checked. At the time of data transfer in step S18, it is assumed that the transmission result # 5 in FIG. 4 is being transmitted before the transfer of each record, and that the transmission is successful after the transfer. In step S23, it is determined that the transmission notification result # 6 in FIG. 4 has been delivered. In step S25, FIG.
Is deleted by one record, and the transmission request data number # 4 in FIG. 5 is decremented by one. In step S33, the transmission result # 5 in FIG. 4 is determined to have failed. In step S35, the transmission notification result # 6 in FIG. 4 is determined to have been transmitted. In step S37, one record is deleted from record R1 in FIG.
The transmission request data number # 4 in FIG. 5 is decremented by one.

As shown in FIG. 6, the receiving-side communication device 91
Is used base station information,
The information is transmitted to the radio base station 5 together with the channel assignment request and the like, and the status information of the own device of the receiving device monitoring server 8 of the mobile communication network 6 is updated.

In this way, the transmitting terminal 12 or 22
Is transmitted to the data communication telephone number of the receiving communication device 91, the mobile communication network 6 immediately
The transfer data is temporarily stored in the data storage server 7 of the mobile communication network 6 without connecting the line. After the transfer from the transmitting device 1 or 2 is completed, if the receiving device 9 is in a receivable state, the connection is made immediately and the data is transferred to the receiving device 9. If the receiving device 9 is not in the receivable state, the receiving device 9 monitors the receiving device 9 until it becomes receivable.

From the transmitting terminal 12 or 22 to the receiving terminal 92
When data is transmitted from the transmitting terminal 12 or 22 without directly connecting a line, the wireless line portion on the receiving side is not used, so there is little danger of interruption of transmission due to line disconnection or the like.
Further, it is also possible to receive the data from the receiving terminal 92 to the data storage server 7 by checking the presence or absence of data addressed to the own terminal.

Referring to FIGS. 7 and 8, a wireless communication network system according to a second embodiment of the present invention will be described. FIG. 7 schematically shows a configuration of a wireless communication network system according to a second embodiment of the present invention. The wireless communication network system of FIG. 7 replaces the communication device 91 of the receiving device 9 in the system of FIG.
The receiving device 9A includes a receiving communication device 91A having a data storage memory 93. The configuration of the other parts is substantially the same as that of FIG.

The data storage memory 93 provided in the receiving side communication device 91A stores transfer data from the data storage server 7 of the mobile communication network 6. In this way, by storing the transfer data from the data storage server 7 in the data storage memory 93 in the receiving-side communication device 91A, the receivable condition in the receiving device 9A is not using the line, and the receiving-side communication device The power of 91A is turned on, and it is only in the communicable area. That is, in the normal waiting state,
There is no need to connect the receiving-side communication device 91A to the receiving terminal 92, and it is not necessary to turn on the power of the receiving terminal 92, and effective use of the power of the receiving terminal 92 is achieved. The transmission data stored in the data storage memory 93 is transferred to the receiving terminal 92 as soon as the communication device 91A is connected to the receiving end 92, and the process is terminated.

Further, since the data transfer procedure from the data storage server 7 of the mobile communication network 6 is also communication of only the mobile communication network 6, communication using a special protocol according to the wireless characteristics of various wireless line systems is possible. Therefore, there is no need to add any special function to the receiving terminal 92 in accordance with this protocol. Further, even while the data communication is forcibly stopped, the data transfer is started by requesting the transfer from the receiving terminal 92 to the data storage server 7.

The detailed operation in this case will be described with reference to FIG. The flowchart of FIG. 8 is different from the flowchart of FIG. 3 in that steps S16 to S20 are replaced with steps S41 to S51.

That is, as described above, step S
15 indicates that the line of the transfer destination receiving device 9A is not in use and the receiving side communication device 91A
Is turned on, and the communication device 91A is present in the communicable area. If it is determined in step S15 that the receiving device 9A is in the receivable state, the receiving communication device 91A is immediately called (step S41), and the line between the data storage server 7 and the communication device 91A is connected (step S41). S42), and transfer the transmission data to the data storage memory 93 in the communication device 91A (step S43).

If the transfer is interrupted due to a line trouble or the like during the data transfer in step S43 (step S4
4) Returning to step S41, the connection is automatically re-established, and the transfer-incomplete portion is transferred. When the transfer of the transmission data is completed, the line between the data storage server 7 and the communication device 91A is disconnected (step S45).

The communication device 91A on the receiving side performs step S4.
In 5, when the line between the data storage server 7 and the communication device 91A is disconnected, the state of the receiving terminal 92 is monitored (step S46), and the operation waits until the receiving terminal 92 is activated (step S47). In step S47, when the receiving terminal 92 is activated, the communication device 91A is connected to the receiving terminal 92 (step S48), and the data stored in the data storage memory 93 in the communication device 91A is transmitted to the receiving terminal 92. (Step S49). When the transfer of the transmission data is completed, the data stored in the data storage memory 93 in the communication device 91A after the transfer is deleted (step S50), and the line to the mobile communication network 6 is once reconnected,
It notifies the receiving device monitoring server 8 that data reception has been completed, and disconnects the connection between the communication device 91A and the receiving terminal 92 (step S51).

In this case, when the data storage server 7 is notified from the receiving device monitoring server 8 that the receiving process in the receiving device 9A has been completed, the data storage server 7 performs the same processing as in step S2 in FIG.
1 to S25 are performed.

Therefore, in step S28, if no connection is made from the receiving terminal, the flow shifts to step S41, and if there is data in step S30, the flow shifts to step S42.

As described above, by mounting the data storage memory 93 on the receiving side communication device 91A, the receiving terminal 92
, There is no need to always turn on the power and connect, and terminal resources can be used effectively. Also, when the transfer is interrupted, the mobile terminal 6 automatically reconnects and retransmits the data between the mobile communication network 6 and the receiving-side communication device 91A. No need to take.

Referring to FIGS. 9 to 11, a third embodiment of the present invention will be described.
A wireless communication network system according to the embodiment will be described. FIGS. 9 to 11 schematically show first to third setting methods for forcibly stopping automatic reception from a receiving device in a wireless communication network system according to a third embodiment of the present invention. The configuration of the wireless communication network system in this embodiment is the same as the configuration in FIG.

In the first setting method, as shown in FIG.
A call is transmitted from the receiving communication device 91 to the mobile communication network 6 with a specific telephone number, and the receiving device monitoring server 8 in the mobile communication network 6 is transmitted.
By sending the data communication stop request of the own device to
The receiving-side communication device 91 can forcibly stop communication to the data communication telephone number.

That is, the receiving terminal 92 makes a call to the specific telephone number described above (step S61), and connects to the receiving device monitoring server 8 of the mobile communication network 6 (step S62). Then, a request for forcibly stopping the automatic data reception is sent to the receiving device monitoring server 8 (step S6).
3) Disconnect the line (step S64). Thereafter, even if the data to be transmitted to the receiving terminal 92 is stored in the data storage server 7, a call to the receiving device 9 is not automatically made (step S65).

In this way, even if the transmission data to the own device is transmitted, the transmitted data is
The data is kept stored in the data storage server 7 and the call from the mobile communication network 6 is not automatically received. Therefore, it is possible to prevent a call with high urgency from being interrupted. The receiving side can determine the time point at which the possibility of an emergency call is low by itself, access the data storage server 7, and fetch the received data.

In the second setting method, as shown in FIG. 10, the setting is made to stop the automatic reception by the data communication telephone number by operating the receiving communication device 91 (step S71). Thereafter, it is made not to respond to the call with the data communication telephone number (step S72). Even in this case, the same function as described above can be achieved. However, when the data addressed to the receiving device 9 is sent, the mobile communication network 6 repeatedly calls the receiving device 9, which may increase the load on the mobile communication network 6. .

Therefore, in the third setting method, as shown in FIG. 11, the information of the stop of the automatic reception in the receiving-side communication device 91, that is, the automatic incoming communication forced stop request (see FIG. 6) is set (step S1). S81). Next, the data communication forcible stop information is transmitted to the receiving device monitoring server 8 at any time together with the receivable state information and the like (see FIG. 6) (step S8).
2). The data storage server 7 stops automatic reception in response to the data communication forced stop information (step S8).
3). Even in this case, the receiving side can stop automatic reception using the data communication telephone number. This method is also effective in that no special operation by the receiving operator is required.

In the above-described first to third embodiments, the data communication to the specific recipient at the specific telephone number is described by one-to-one communication, but as described with reference to FIG. Using the system according to the present invention makes it possible to transmit data addressed to an unspecified recipient.

That is, in FIG. 1, the specific telephone number and the transfer data are stored in the data storage server 7 of the mobile communication network 6, but the destination type # 4 in the record of FIG.
It is assumed that an unspecified person's number is set in advance, and that anyone can retrieve the transfer data to that number. Therefore, the mobile communication network 6 automatically calls the recipient,
Although the transmission data is not transferred, the data transfer is started when an arbitrary receiver requests the data storage server 7 to transfer the data.

Further, the destination type # in the record shown in FIG.
4, a specific telephone number group is registered in advance, and a specific telephone number is given to each group, so that the transmitting terminal can transmit data to all the groups by one transmission operation, that is, transmit the data to the same group. Broadcast communication becomes possible. That is, when data addressed to the group telephone number is stored in the data storage server 7, the same data is automatically transferred to each receiving device in the group.

As described above, in the wireless communication network system of the above embodiment, there is no need to simultaneously restrict the transmitting and receiving parties to the communication operation. From time to time,
The transmission data can be transmitted, and the receiver can automatically receive the data by setting the receiving device in a receivable state at a convenient time. The receiver can forcibly stop receiving the received data, and can also receive the stored received data whenever desired.

In the unstable communication using the mobile communication network, since the transmitting and receiving parties are not directly connected to each other, the possibility of line disconnection during the data transfer of each of the transmitting and receiving is reduced as compared with the direct connecting. There is no need to always turn on the power of the receiving device, and terminal resources such as a battery can be effectively used. In addition to fixed communication between one-to-one communicators, broadcast communication for one-to-many groups or data extraction by unspecified persons is possible, and the range of use of the mobile communication network is expanded.

If a data storage memory is mounted on the receiving communication device, the receiving terminal does not need to be operated even during reception of the stored data, and the receiving terminal can fetch data from the communication device at any time. Therefore, terminal resources such as the power supply of the receiving terminal can be used more effectively. Also, since the data transfer from the data storage server of the mobile communication network to the receiving communication device is data communication within one communication network, it is possible to use a special protocol according to the characteristics of each wireless line. Yes, it does not require any special function from the receiving terminal.

Further, even if the line is disconnected due to unstable radio conditions during communication or the like, it is easy to automatically reconnect and automatically retransmit the remaining data. There is no need to take measures against wireless communication instability. Since data can be transferred in a minimum communication time, communication costs can be reduced and radio wave resources can be used effectively.
