Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a concentrator transmission communication system, and more particularly to a concentrator transmission communication system that performs a standby connection using an unrelated concentrator transmission line.

[Conventional technology]

Conventionally, this type of concentrator transmission system connects a master station and multiple slave stations such as mobile units via a concentrator transmission line such as wireless, and each time a call occurs to a slave station, the communication channel on the concentrator transmission line is In this system, calls that occur when all communication channels on the concentrator transmission line are busy are sequentially temporarily stored in the master station as waiting calls, and as soon as a communication channel becomes available, a communication channel is allocated and a call is made. The system adopted a waiting-type connection, and the system was configured to notify the calling subscriber that the call had become a waiting call, using voice guidance or the like.

[Problem to be solved by the invention]

The above-mentioned conventional concentrator transmission communication system has a system configuration in which the calling subscriber is notified of the waiting call by voice guidance etc., so the calling subscriber does not know that his/her call is being processed. The problem is that when the number of waiting calls increases, the serviceability and convenience for the subscriber deteriorates significantly, such as knowing only that the call is waiting, and therefore not knowing the estimated waiting time until the call becomes available. There is.

[Means to solve the problem]

The concentrator transmission communication system of the present invention includes a master station and a plurality of slave stations connected to the master station via a concentrator transmission line, and when all communication channels on the concentrator transmission line are busy in the master station, In a concentrating transmission communication system that performs a waiting type connection in which calls that have occurred are sequentially temporarily stored and made into a waiting call, the master station is provided with an order notification that notifies a slave station that has generated a waiting call of the waiting order of the slave station. and call termination information notification means for notifying each of the slave stations of call termination information each time a call in progress is terminated, and the slave stations are provided with a waiting order notified from the master station. The present invention is equipped with display means for audibly or visually notifying the client, and waiting order subtraction means for reducing the waiting order of the own station in accordance with end-of-call information sent from the master station.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a concentrator transmission communication system according to the present invention.

In FIG. 1, this embodiment shows a subscriber terminal 1-

The master station 2 interfaces with the subscriber interface circuits 101 to Ion that interface with the subscriber terminals 1-1 to 1-n, and the main control unit 50 for transmitting information such as call termination, etc., according to the control from the main control unit 50. , subscriber interface circuits 101 to 10-n and speech channel transceiver 3
A communication path switch 20 that connects communication paths between 0-1 and l (
and the slave stations 3-1 to 3-1 through the communication channel on the wireless transmission path.
Communication channel transmitters/receivers 30-1 to 30-k that connect communication paths to slave stations 3-1 to 3-m communicate call connection information such as incoming and outgoing calls to slave stations 3-1 to 3-m via control channels on wireless transmission paths. A control channel transmitter/receiver 40 that transmits and receives calls, and a main control circuit 50 that monitors and controls the entire system of this embodiment, such as managing call channels and processing call connections, and a main control circuit 50 that monitors and controls the entire system of this embodiment, such as managing call channels and processing call connections. The present invention also includes a waiting call storage circuit 60 for temporarily storing calls in the order in which they occur.

The slave station 3-1 receives the signal sent from the master station 2 and outputs the control channel information to the control unit 80, and the receiving unit 70 which outputs the signal of the communication channel assigned to the local station to the handset 100. and the master station 2 via the control channel on the wireless transmission path.
A control unit 80 performs call connection control and monitors control of the entire slave station 3-1, a transmitting unit 90 transmits signals to the master station 2 via the wireless transmission path, and Display 1 for displaying station or subscriber service information
10, and a handset/receiver 100 that interfaces voice signals etc. of slave station subscribers.

Note that the slave stations 3-2 to 3-m also have the same configuration as the slave station 3-1, and illustration of their internal configurations is omitted.

Next, the operation of this embodiment will be explained.

For example, when a call is made to the slave station 3-1 while all communication channels on the wireless transmission path are busy, the call signal is sent to the control unit 80.
The signal is sent from the transmitter 90 to the master station 2 via the control channel.

In the master station 2, the call is sent to the main control unit 50 via the control channel transceiver 40, where it is determined to be a waiting call. The call determined to be a waiting call is temporarily stored in the waiting call storage circuit 60, and the waiting order (the number of calls stored in the waiting call storage circuit 60) is transmitted from the control channel transceiver 40 via the control channel. It is sent to the calling slave station 3-1.

The slave station 3-1, which has received the waiting order, notifies the subscriber of the slave station 31 that the call has become a waiting call under the control of the control unit 80, and also displays the waiting order on the display 11.
Display at 0.

On the other hand, the main control unit 5 of the master station 2 that manages the communication channel
0 broadcasts call termination information to each slave station 3-1 to 3-m via a control channel every time a call ends.

In the slave station 3-1 having a waiting call, each time the receiving unit 70 receives this call termination information, the control unit 80 reduces the number of waiting calls displayed on the display 1]-〇. -Provide information on the approximate time until the start of a call to the slave station subscriber 1.

Although the present invention has been described above with respect to an embodiment of the system shown in FIG. 1, the present invention is not limited to this.
For example, the subscriber terminals 1-1 to 1-n shown in FIG. 1 are connected via subscriber lines of the general public network at the interface positions, and the telephone terminals of the general public network and the slave station 3-n shown in FIG. 1~
It is clear from the above description that the present invention can be applied to a system in which calls are made between B=m.

〔Effect of the invention〕

As explained above, the present invention provides an audible and audible message indicating the waiting order of slave stations to a master station or a calling subscriber when a waiting call occurs in a concentrator transmission communication system that employs a waiting type connection. The system configuration is provided with a waiting order subtraction means that notifies by means of a visual display, etc., and reduces the audible and visually displayed waiting order each time a call in progress is terminated (that is, each time the number of waiting calls decreases). As a result, it is possible to provide a waiting subscriber with an estimate of when a call will be available, thereby improving serviceability and convenience for the subscriber compared to the past.
