Abstract

PURPOSE:To reduce the cost and miniaturize an equipment and improve the processing effect by sharing a signal transmitter-receiver among plural data terminals to make the number of signal transmitter-receivers smaller than that of node equipments and distributing and arranging them in plural optional node equipments. CONSTITUTION:Signal transmitter-receivers 2 are shared and are assigned to terminals 3 on demand and are distributed and installed in plural node equipments 1. Assignment and release of signal transmitter-receivers are collectively managed by a master node 1. An idle signal transmitter-receiver is hunted when a certain terminal originates a call. A line is set between the originating terminal and the signal transmitter-receiver, and a destination selecting signal is received. A line is set between the selected destination terminal and the signal transmitter-receiver, and the destination terminal is called. When the destination terminal responds, a line is set between both terminals and the signal transmitterreceiver is released. The number of signal transmitterreceivers is smaller than that of terminals, and the load is properly distributed to respective signal transmitterreceivers because signal transmitter-receivers to be shared are distributed and installed in plural node equipment.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a signal transmitter/receiver management system, and more particularly:
This paper relates to a method for controlling the installation of signal transmitters and receivers in a distributed processing type data circuit switching network and the allocation to each terminal.

[Conventional technology]

In conventional data line switching networks, signal transmitters and receivers are not shared but are installed individually for each terminal.

Furthermore, even if they were shared, they were configured in a centralized manner, and no consideration was given to load distribution.

In addition, as this type of device, for example, Mitsubishi Electric Branch V
ot, 58 A2.rM described in 1984
ELNET-R32j and the like are known.

[Problem that the invention seeks to solve]

Conventional systems have problems in terms of cost when each terminal is individually provided with a signal transmitter/receiver. Also.

Even when a single transmitter/receiver is shared by multiple terminals without having to install them individually, conventional systems have problems in terms of load concentration because the signal transmitters/receivers are installed centrally.

An object of the present invention is to distribute the load and reduce costs.

[Means for resolving the gap]

According to the present invention, in order to achieve the above object, the following means are combined.

(1) Signal transmitters and receivers are shared and assigned to terminals as necessary.

(2) Signal transmitters and receivers are distributed and installed in multiple node devices.

(3) Allocation and release of signal transceivers will be managed collectively by the master node, and for this purpose, the master node will
A signal transceiver management table will be provided.

[Effect]

When a terminal with a number of terminals makes a call, one free signal transmitter/receiver is hunted. A line is set up between the calling terminal and the signal transmitter/receiver, and a partner selection signal is received. Next, a line is set up between the selected partner terminal and the signal transmitter/receiver,
When a call is made and the other terminal answers, a line is established between the two terminals and the signal transceiver is released.

As described above, according to the present invention, the number of signal devices can be far smaller than the number of terminals because the signal devices are shared. In addition, a signal device to be shared can be distributed to multiple node devices using a membrane+ff
The load is appropriately distributed to each signal device.

〔Example〕

An embodiment of the present invention will be described below.

FIG. 1 shows an example of a distributed network system having a data line switching function such as X20/X21. In the figure, 1' is a master node, 1 is a general node, 2 is a signal transmitter/receiver, 3 is a data terminal, and 4 is a time division multiplex transmission line. System control information between nodes is passed through packets.

The number of signal transceivers 2 to be installed is determined depending on traffic. The signal transceivers 2 are distributed and installed in the general nodes 1 (including the master node 1'), and installation information and usage status are managed by the master node in a signal transceiver management table, which will be described later.

The ID of the originating terminal is set when it is in use, and zero is set when it is not in use.

4 (4) to (Q) show the line setting procedure from when the data terminal makes a call until it is connected to the other party.

Reference numerals 1 to 4 are the same as in FIG. 1, and 5 is a connection line between the originating terminal and the signal transmitter/receiver used for transmitting the selection number;
Reference numeral 6 denotes a connection line between the destination terminal and the signal transmitter/receiver, which is used for transmitting a paging signal.

Next, the signal transmitter/receiver management system according to the present invention will be explained according to the sequence shown in FIG.

(1) When a terminal makes a call, that node sends a signal transceiver hunt request to the master node. At this time, the ID of the calling terminal is also notified.

(2) The master node refers to the signal transceiver management table shown in FIG.
De registration).

At this time, line 5. shown in Figure 44. 6. Decide on 7,
Notify the originating node along with the ID of the signal transmitter/receiver.

(3) The originating node sends all number reception requests to the node equipped with a signal transceiver and sets up a line with the signal device.

(4) The signal transmitter/receiver equipped node controls the signal transmitter/receiver to send a selection signal transmission enable signal to the originating 9Q terminal, and after receiving the selection signal, issues a number translation request to the master node.

(5) The master node converts the destination selection number into an implementation address and notifies the requester of the result.

(6) The node equipped with a signal device instructs the first destination node to set up a line between the destination terminal and the signal transmitter/receiver, and then controls the signal transmitter/receiver to send out a paging signal.

(7) Upon detecting a response from the destination side, the node equipped with a signal device issues a line switching instruction to the destination node. This results in
Both terminals are connected by a line.

(8) The originating node sends a signal transceiver IJ request to the master node.

(9) The master node clears the corresponding user ID on the signal transceiver management table and releases the signal transceiver.

The above steps complete the connection between the terminals.

〔Effect of the invention〕

According to the present invention, by sharing signal transmitters and receivers, the number of installed signal transmitters and receivers can be much smaller than the number of terminals.
It is possible to reduce costs and downsize the device. Furthermore, by distributing the signal transmitters and receivers, it is possible to distribute the load on the node devices, thereby improving the processing efficiency of each node device, for example, increasing the speed of supported terminals and improving the performance of the system.
