Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication line control system in a subscriber telephone and a data communication system, and more particularly to a communication line control system for performing call connection control with reference to priorities.

[0002]

2. Description of the Related Art In a conventional communication line control system, regarding a line control in a subscriber radio telephone system, a code signal generator of a control unit of a portable unit generates a priority code, and a line must be free using this priority code. For example, there has been a technique of interrupting and establishing a communication line. This technique is described in, for example, Japanese Patent Application Laid-Open No. 4-96432.

[0003]

However, in the above-mentioned conventional communication line control, important communication is performed because an interrupt is forcibly generated one after another when the caller performs communication of the priority code. The line may be interrupted.

[0004] Also, since the priority code can be assigned only to the caller side, and the method of assigning the priority code is fixed, the called party preferentially connects only by distinguishing so-called emergency communication from normal communication. There was no means for the communications that they wanted.

[0005] Further, in the communication without the priority code, it was not possible to inform the called party of the presence or absence of the transmission.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an incoming call detecting means for judging the presence or absence of an incoming call on the called side and a function for setting the desired priority for each caller on the called side. Is to preferentially assign a line to a communication that desires communication and to control the communication line smoothly.

[0007]

According to the communication line control system of the present invention, the telephone number of the other party, the telephone number of the caller, the place of origination and the time of origination are set between the caller and the callee. A means for notifying the information, an ID database for registering the notified information in the called side exchange, and a function for calculating the priority, which will be described in detail later, for the caller's communication based on the parameters set by the called side The present invention is characterized in that the calling exchange is notified of the calculated priority, and the line is connected according to the priority.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an embodiment in which the present invention is applied to a subscriber telephone system will be described. The communication line control system according to the present invention notifies the destination exchange of information including the telephone number of the other party, the telephone number of the caller, the call place and the call time between the exchanges, and transmits the parameters set by the telephone of the callee. To calculate the priority of the communication and send the result back to the originating exchange. Then, based on this priority, the communication line is controlled smoothly. Further, information including the telephone number of the other party, the telephone number of the caller, the call place and the call time notified to the callee exchange is registered in an ID database connected to the callee exchange. [Embodiment] FIG. 1 shows a configuration diagram of an embodiment of the present invention.

FIGS. 2A and 2B show flowcharts of the communication line control system of the present invention. First, the telephone number of the other party, the telephone number of the caller, the call place and the call time are registered in the ID database 4 of the receiving side exchange 2.

Next, it is checked whether the communication line 5 is vacant. If the line 5 is vacant, the line 5 is connected as usual. If the line 5 is not vacant in the originating exchange 1, the priority of the communication is calculated using the parameters registered in the destination exchange 2 as described later, and the value of the priority is calculated in the originating exchange 1. Notify. This notification is performed using signaling between exchanges.

[0011] The originating exchange 1 compares the received priority with the priority of the other communication, and checks whether or not the communication having the lower priority uses the line.

If there is a communication having a lower priority than the received communication among the communication using the line at that time, the line used by the communication is released and the line is connected to the communication having a higher priority. . If there is no communication lower than this priority among the communication using the line, the communication has a waiting time allocated according to the priority and enters a waiting state.

[0013] As soon as a line is available, connection is started from a communication with a higher priority. Here, when the line is not connected and the waiting time assigned for each priority elapses, the waiting state is automatically released, and information that has not been received is added to the data registered in the receiving side exchange 2. .

Next, parameters for calculating the priority (M) will be described.

As the parameters for calculating the priority (M), the telephone number of the party to which the called party wishes to connect, the location of the caller, the waiting time, the number of calls within a fixed time, and the like are used.

For example, the telephone number of the desired partner is A1,
A2 can be assigned to the calling place, A3 can be assigned to the waiting time, A4 can be assigned to the number of calls, and a weight can be assigned according to the importance of the information. Then, the priority (M) for the communication is determined by calculating the sum of the weights of these parameters as shown in the following equation (1).

M = A1 + A2 + A3 + A4 (1) These weights are not invariable values, but can be variably set according to the state of the called party.

FIG. 3 shows the telephone number of the other party registered in the ID database 4 connected to the called side exchange 2 when the line is not connected in the called side exchange 2, It is shown that the information of the caller's telephone number, the place of the call, and the time of the call is added to the information of the unreceived call, and the information indicating that the call was made but is not received can be known on the called side.

FIG. 4 is a diagram showing a configuration when the present invention is applied to a subscriber radio telephone. In FIG. 1, a caller's telephone 6 and a receiver's telephone 7 are exchanges 1 and 2, respectively.
Had been directly to. However, FIG. 4 shows that the wireless line 10 can be applied to the subscriber wireless telephone system between the calling wireless telephone 8 and the calling wireless base station 6 and between the called wireless telephone 9 and the called wireless base station 7. I have. As a result,
The priority is determined by the method described above, and the setting of the wireless channel can be released.

[0020]

As described above, the communication line control system according to the present invention calculates the priority for the communication requesting the line connection by using the priority calculation parameter set by the called party, and establishes the communication line. This is a control method of allocating.

By using this control method, a communication line can be smoothly allocated to a communication that the called party wants to connect to, and the use efficiency of the line can be improved. Also, even if a communication line cannot be secured, the telephone number of the other party, the telephone number of the caller, the call place and the call time can be registered in the ID database of the called exchange, and the information can be monitored from the called telephone. Thus, the called party can know that there was a communication that was not connected in the communication addressed to him / her. As a result, it is possible to occupy the line more than necessary and to avoid unnecessary connection of the communication line, to prevent congestion and the like, and to obtain an effect of improving the use efficiency of the communication line.
