Field of the Invention The present invention relates to a communication control system that has a plurality of hierarchical communication control processes when connecting a computer or a computer and a device. FIG. 4 is an explanatory diagram of the industrial application field of the present invention. In the figure, computer A and computer B each have communication control processing hierarchically from the first layer to the nth layer. The layer close to the first layer is called the lower layer,
The closer the layer is to the n-th layer, the higher the layer is called. The closer the interface is to the first layer, the closer it is to the physical interface, and the closer it is to the nth layer, the closer the interface is to the user's program. In order to terminate communication between computer A and computer B, processing in all layers from the nth layer to the first layer must be terminated. This is because each layer has, for example, memory to keep track of all communication status, and a timer that monitors until the processing in the lower layer is completed, so each computer can perform disconnection (release) processing in all layers. This is because the next process cannot be executed until the process is completed. It is desired that this cutting process for all layers be performed in as short a time as possible.

There was a problem in that the procedure for cutting the road was complicated. Furthermore, since the procedure for disconnecting the communication path between computers is complicated, there is a problem in that the disconnection process takes a long time. The length of the disconnection time affects the hold time of resources such as lines and data used by the computer, and the length becomes a problem especially during high traffic.

Hereinafter, 1 will be referred to as the own station, and 2 will be referred to as the opponent station. The local station 1 and the partner station 2 each perform communication control processing using a plurality of layers from the first layer to the n-th layer. Each layer has data indicating whether to perform the release procedure in the same layer of the local station and the partner station, or to release the own layer by releasing the lower layer in each of the local station and the partner station. If a lower layer is released and the own layer is released, a release notification/release is sent between the layers.
A release confirmation event is provided, and the upper layer is released at the same time by the release procedure of the lower layer.

In each of these, release notification signals are sent to predetermined lower layers sequentially from the top layer, and release requests and release confirmations are exchanged between the same layer of the local station and the other station only in layers lower than the predetermined lower layer. In response to the release confirmation, each of the local station 1 and the partner station 2 is configured to notify a release confirmation signal from a predetermined lower layer to the highest layer in sequence.

処理の通信路解放とみなすことができる。[Operation] Communication path release processing between local station 1 and partner station 2 is performed only in layers lower than a predetermined lower layer, so communication control is performed in middle and upper layers above the predetermined lower layer. There is no need for communication path release processing between local station 1 and partner station 2 during processing, and notification of release notification signals and release confirmation signals between layers within the same station can be done in a short time without any complicated procedures. Therefore, own station 1 and opponent station 2 only in layers lower than the predetermined lower layer.
The communication path release process between the two layers can be considered to be the communication path release process for substantially all layers of communication processing.

Either the notification of unavailability due to termination processing from the layer one layer below within a certain period of time after being passed to the layer one layer below is not regarded as a failure, or the release confirmation is confirmed from the layer one layer below. Isolation from failure is done by notifying the signal to that layer.

第３層まで送る。The procedure for releasing the communication path after data communication is completed is as follows. First, in each of computers 1 and 2, the n-th layer does not send a release request signal requesting (or displaying) release to the n-th layer of the other station, and the (n-1
) is issued an n-th layer release notification TI(n) only to the layer. In the figure, for simplicity, the (n-1)th layer is designated as the mth layer. The m-th layer receives a release notification TI(n) from the n-th layer.
After receiving the message, perform the release procedure on the own layer. The m-th layer is the own station's (
The m-th layer release notification TI(m) is issued only to the m-1) layer. Thereafter, similar release notifications are sent sequentially from the (m-1)th layer to the third layer.

対し解放通知信号ＴＩ（２）を出す。The second layer, which has received the release notification TI(3) from the third layer, executes a release procedure with the second layer of the partner station 2. This release procedure is similar to the release procedure in each layer in the past. The second layer of the own station sends a release request signal to the second layer of the opposite station, and the second layer of the opposite station 2 sends a release confirmation signal TC(
2), it issues a release notification signal TI(2) to the first layer, which is a lower layer of the second layer.

In this embodiment, the layers that actually perform the release procedure with the layer of the partner station are the second and first layers.
A similar effect can be obtained with just the layers. The number of lower layers that actually execute the release procedure between the local station and the other station is determined by the minimum number of layers required by the communication system.

A communication processing method that performs a plurality of communication control processes in a plurality of layers, with one side between computers or between a computer and a terminal serving as a local station (1) and the other station serving as a partner station (2). As a release procedure for each of multiple layers, the own station (1
) and the partner station (2), or both the own station (1) and the partner station (2) each have data on whether to release their own layer by releasing the lower layer. When releasing a layer, the layer itself is released, a release notice/release is sent between the layers.
A communication control method characterized by setting a release confirmation event and releasing the upper layer at the same time according to the release procedure of the lower layer.

方式。2. A communication processing method in which one of the computers or a computer and a terminal is the local station (1) and the other is the partner station (2), and a plurality of communication control processes are performed in a plurality of layers, respectively. As a release procedure from the highest layer to a predetermined lower layer among multiple layers, each of the local station and the partner station notifies the release notification signal sequentially from the highest layer to the predetermined lower layer. However, only in layers lower than the predetermined lower layer, release requests and release confirmations are sent and received between the same layer of the local station and the partner station, and in response to the release confirmation, each of the local station and the partner station A communication control method in which a release confirmation signal is sequentially notified from the predetermined lower layer to the uppermost layer.
