The mobile radio device is provided with a talkie sending means for sending a call to a mobile radio device, and is configured to notify a subscriber of a public communication network who has made a call to the mobile radio device of a call limit time before starting a call.

Regarding the story system.

In recent years, various mobile communication systems have been introduced.
Among these, in convenience radio (phono) systems that improve the efficiency of radio wave use, calls between mobile radios and public communication network subscribers are
Call time limits are set in 20 second intervals.

The call time limit changes depending on the traffic situation, but in the conventional system, only the user of the mobile radio device is notified of the time limit. Even if subscribers to the public communications network are informed that there is a limit on calls, they are not informed of the time limit for the call they are about to start, so they are not aware of how long the call can be made. As I made the call, I was unsure whether I would be able to do so.

For this reason, there is a need for a mobile radio telephone system that notifies subscribers of the public communication network of the time limit for the call by means of a talkie when starting a call.

[Conventional technology]

FIG. 3 is a block diagram of a mobile radio telephone system according to the prior art, and FIG. 4 is a sequence diagram up to the start of a call according to the prior art.

This is the symbol in the figure.

When a subscriber (including a public telephone) 15 accommodated in the public communication network 14 calls a mobile radio [16], he/she dials the representative number of the mobile radio telephone service (■). The dialed number is transmitted to the mobile radio base station 1 in the public communication network 14.
It is used to select the line to be connected to one connection processing device 12, and the subscriber 15 is connected to the empty connection processing device 12. When the connection processing device 12 receives an incoming call, it puts the public communication network 14 into a response state and then sends out a second dial tone (@).

When the subscriber 15 hears the second dial tone, he dials the number of the mobile radio 16 to which he wishes to connect (■). When the connection processing device 12 receives the dialed number, it transmits the mobile radio number to the radio line via the base station radio [13] (o). When the corresponding mobile radio device 16 responds (@), the connection processing device 12 completes the communication path between the public communication network 14 and the base station radio device 13, and the communication between the subscriber 15 of the public communication network 14 and the mobile radio device 16 is completed. is started (■).

The call will be forcibly disconnected after a certain period of time depending on the traffic situation at the time.The mobile radio device side will be notified of the call limit time by a broadcast signal, but the caller on the public communications network will be notified of the call time limit. We have not specifically notified them.

[Problem to be solved by the invention]

As mentioned above, in the conventional mobile radio telephone system,
Even if call time limits are set, callers are inconvenienced because subscribers to public communication networks are not notified of the call time limit for each call.

SUMMARY OF THE INVENTION An object of the present invention is to notify a subscriber of a public communication network who has made a call to a mobile radio device of a call time limit before starting the call.

[Means to solve the problem]

FIG. 1 is a diagram explaining the principle of the present invention.

In the figure, 1 is a mobile radio base station, 2 to 5 are devices installed in the mobile radio base station 1, and 2 is a public communication network 6 on one side,
a connection processing device 3, the other of which is connected to the base station radio 5, and processes a connection call between a subscriber 7 of the public communication network 6 and the mobile radio 8 via the public communication network 6 and the base station radio 5; is provided in the connection processing device 2, and when a subscriber 7 of the public communication network 6 makes a call to the mobile radio, it notifies the subscriber 7 of a call limit time before starting the call. Call time notification means 4 controls the call time notification means 3.
A talkie receiver that receives control information including a call limit time from a user and sends a talkie message indicating a call limit time corresponding to the control information to a subscriber 7 of the public communication network 6 via the call time notification means 3. - Sending means, 5 is a base station radio.

Further, 6 is a public communication network, and 7 is a mobile radio device that is connected to the base station radio device 5 by radio.

[Effect]

In FIG. 1, when a subscriber 7 of a public communication network 6 calls a mobile radio 8, he dials a representative number of the mobile radio telephone service. The dialed digits are used to select a line to be connected to the connection processing device 2 of the mobile radio base station 1 in the public communication network 6, and the subscriber 7 is connected to the connection processing device 2 of the mobile radio base station 1.
connected to.

When the connection processing device 2 is connected to the public communication network 6, it enters a response state to the public communication network 6, and then the call time notification means 3 determines the currently applicable call limit time based on the traffic status record (not shown). is calculated, and control information including call time limit information is sent to the talkie sending means 4. When the talkie sending means 4 receives the control information, it sends a talkie message corresponding to the received talk time limit information to the call time notification means 3. The talkie
The message is sent to the public communication network 6 via the call time notification means 3 and listened to by the subscriber 7. This allows the subscriber 7 to know the time limit for the call he or she is about to make before starting the call.

When the connection processing device 2 finishes sending the talkie message, it sends a second dial tone to the subscriber 7 by a method not shown in the drawings, and thereafter, upon receiving the mobile radio number from the subscriber 7, the corresponding mobile radio device is transferred. The wireless device 8 is called, and in response to the mobile wireless device 8's response, the connection processing device 2 completes the communication path between the subscriber 7 of the public communication network 6 and the mobile wireless device 8, and starts a conversation.

〔Example〕

FIG. 2 is a diagram showing an embodiment of the sequence up to the start of a call in the mobile radio telephone system according to the present invention.

Hereinafter, FIG. 2 will be explained based on the configuration of FIG. 1.

■ to ■ are symbols in FIG.

A subscriber 7 of the public communication network 6 in FIG.
8, dial the main number of the mobile radio telephone service (■). The idle connection processing device 2 of the mobile radio base station 1 is selectively connected by the dialed number. When the connection processing device 2 receives a call from the public network, it uses a circuit (not shown) to loop the two-wire line from the public communication network 6 and displays a response. The time limit is calculated and control information including call time limit information is sent to the talkie sending means 4. When the talkie sending means 4 receives the central control unit information, it sends a talkie message corresponding to the received talk time limit information to the call time notification means 3. The talkie message passes through the call time notification means 3, is sent to the public communication network 6, and is listened to by the mobile radio caller 7 (■). This allows the mobile radio caller 7 who made the call to know the call time limit before starting the call.

When the connection processing device 2 finishes transmitting the talkie message, it transmits a second dial tone to the mobile radio caller 7 through a circuit (not shown) (■). Mobile radio caller 7
listens to the second dial tone and dials the number of the mobile radio to which he or she wishes to connect (■). When the connection processing device 2 receives the dialed number, it transmits the mobile radio device number to the radio line via the radio device 5 (■). In response to the response (■) from the corresponding mobile radio device 8, the connection processing device 2 completes the communication path between the mobile radio 0 caller 7 and the mobile radio device 8 and starts a conversation (■).

Note that the talkie message with the above call time limit is sent only when a call is made from the public communications network, and when a mobile radio is connected to a subscriber of the public network, No talky messages are sent to subscribers.

This is based on the idea that a sufficient effect can be obtained by notifying the caller, who is in the position of leading the call, of the call time limit. By the way, mobile radios are notified of the call time limit in a broadcast signal (details omitted).
In the case of a call originating from a mobile radio, the user of the mobile radio is aware of the call time limit and can lead the call to the subscriber of the public network, so there is little inconvenience in the call.

〔Effect of the invention〕

As explained above, according to the present invention, when a subscriber of a public communication network makes a call to a mobile device, it is possible to know the call time limit for that call before starting the call. This greatly contributes to improving the services of mobile radio telephone systems.
