Accordingly, the present invention provides a plurality of request reception devices that receive requests for connection of a line between a storage type communication processing device and a terminal device, a selection device that selects one of the request reception devices, and a selection device that selects one of the request reception devices. a storage type communication processing device for selecting one of the request receiving devices and for calls registered in the selected device; The gist of this invention is to identify the line connection requesting means for requesting line connection between terminal devices.

(Function) This invention's accumulated old information communication network (Puru communication system 1lII)
In the device, a line connection request is registered in one of the plurality of request receiving devices, one of the plurality of registered request receiving devices is selected, and the line connection request is registered in the selected device. A line connection request is being made for the current call.

(Example) Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a schematic diagram of a storage-based information communication network that provides a storage-type information communication I8 service that is equipped with a communication control device according to an embodiment of the present invention. The storage old information communication network shown in the figure is a line connection fee that constitutes the communication control device 2Il of this embodiment between the gateway exchanges 7 and 8 and the storage type communication processing equipment 9 in the information communication upper network 10! The configuration is the same as that of the storage/old information communication network shown in FIG. 6 described above except that the H.211 device 11 is provided, and the same components are denoted by the same reference numerals.

The line connection control device 11 includes a line connection holding call registration device group 12 and a line connection holding call registration aill'fJ device 13.
and a line connection request timer 14.

FIG. 2 is an explanatory diagram showing the operation of the communication control system between the storage type communication processing device 29 and the line connection control device 11 shown in FIG.

The storage type communication processing device 9 receives the telephone exchange 5 and the gateway exchange 7 from the information input/output terminal 8i and transmits the accumulated communication information to the other party's information input/output terminal device 2. Identification number, incoming terminal number, line connection priority and other attached information are displayed in the line connection control table @11
and requests line connection to the receiving terminal 2 (processing 1
10). The line-connected fbll 1111 device 11 selects one device from the line-connected call registration device group 12 under the control of the line-connected call registration control device 13 and registers the call (process 120). Methods for selecting one line connection waiting call registration device in the line connection holding call registration control device 13 include a minimum number of waiting calls selection method and a device cyclic selection method, which will be described later.

On the other hand, the line connection requesting device 14 picks out 1"J!5 units from the line connection waiting call registration device group 12 at regular intervals and activates the device. The activated line connection waiting call registration device is the barrier exchange eff for registered calls.
Requests line connection to the incoming information input/output terminal device 2 via i8 (ffi!+!!130>.

If the line connection to the incoming information input/output terminal device 2 is established as a result of the line connection request, the storage type communication processing device 9 is notified of the completion of the line connection together with the call identification number (processes 140, 150>.Storage) After receiving this information, the communication processing device 9 starts transmitting the accumulated communication information (process 160).

If the line connection to the incoming information input/output terminal device 2 cannot be established, the O device 11 that controls the line connection performs the following steps:
