10 group number assigned to each emergency stop group that is determined based on a
range to be affected by an anomaly in each controlled device of the plurality of
controlled devices is associated with each corresponding control device of the plurality
of control devices, and create slice information for connecting to the same number of
user plane functions (UPFs) as the total number of emergency stop groups;
15 a 5G connection unit to register the control device of the 5G connection unit
itself with the 5G network, and acquire UPF destination information, which is
destination information of the UPFs; and
a destination information acquisition unit to, based on the UPF destination
information, associate each emergency stop group number with a destination UPF
20 without duplication of a destination UPF between the emergency stop groups, and store
information in which each emergency stop group number is associated with a
destination UPF in a destination conversion table.
[Claim 2] The communication control system according to claim 1,
25 wherein each control device of the plurality of control devices comprises a destination conversion unit to, when data is to be transmitted to
another control device, convert destination information of the data so as to cause the
data to be transmitted to a UPF corresponding to the emergency stop group to which the
control device of the destination conversion unit itself belongs, based on the destination
5 conversion table; and
a transmission and reception unit to transmit the data, based on the
destination information of the data.
[Claim 3] The communication control system according to claim 1 or claim 2,
10 wherein each control device of the plurality of control devices comprises
an information acquisition unit to acquire emergency stop group
numbers that are set in the emergency stop group information, and
wherein the information creation unit calculates the total number of emergency
stop groups, based on the emergency stop group numbers.
15
[Claim 4] A control device included in a communication control system, the
communication control system including a plurality of control devices that
communicate via a 5G network and a plurality of controlled devices respectively
controlled by the plurality of control devices, the control device comprising:
20 an information creation unit to calculate a total number of emergency stop
groups based on emergency stop group information in which each emergency stop group number assigned to each emergency stop group that is determined based on a
range to be affected by an anomaly in each controlled device of the plurality of
controlled devices is associated with each corresponding control device of the plurality
25 of control devices, and create slice information for connecting to the same number of user plane functions (UPFs) as the total number of emergency stop groups;
a 5G connection unit to register the control device of the 5G connection unit
itself with the 5G network, and acquire UPF destination information, which is
destination information of the UPFs; and
5 a destination information acquisition unit to, based on the UPF destination
information, associate each emergency stop group number with a destination UPF
without duplication of a destination UPF between the emergency stop groups, and store
information in which each emergency stop group number is associated with a
destination UPF in a destination conversion table.
10
[Claim 5] The control device according to claim 4, further comprising:
a destination conversion unit to, when data is to be transmitted to another
control device, convert destination information of the data so as to cause the data to be
transmitted to a UPF corresponding to the emergency stop group to which the control
15 device of the destination conversion unit itself belongs, based on the destination
conversion table; and
a transmission and reception unit to transmit the data, based on the destination
information of the data.
20 [Claim 6] The control device according to claim 4 or claim 5, further comprising
an information acquisition unit to acquire emergency stop group numbers that
are set in the emergency stop group information,
wherein the information creation unit calculates the total number of emergency
stop groups, based on the emergency stop group numbers.

[Claim 7] A communication control method used in a communication control
system including a plurality of control devices that communicate via a fifth-generation
mobile communication system (5G) network and a plurality of controlled devices
respectively controlled by the plurality of control devices, the communication control
5 method comprising:
calculating a total number of emergency stop groups based on emergency stop
group information in which each emergency stop group number assigned to each
emergency stop group that is determined based on a range to be affected by an anomaly
in each controlled device of the plurality of controlled devices is associated with each
10 corresponding control device of the plurality of control devices, and creating slice
information for connecting to the same number of user plane functions (UPFs) as the
total number of emergency stop groups, by a computer;
registering a control device of the computer itself with the 5G network, and
acquiring UPF destination information, which is destination information of the UPFs,
15 by the computer; and
associating, based on the UPF destination information, each emergency stop
group number with a destination UPF without duplication of a destination UPF between
the emergency stop groups, and storing information in which each emergency stop
group number is associated with a destination UPF in a destination conversion table, by
20 the computer.
[Claim 8] A communication control program used in a communication control
system including a plurality of control devices that communicate via a fifth-generation
mobile communication system (5G) network and a plurality of controlled devices
25 respectively controlled by the plurality of control devices, the communication control program causing a computer to execute:
an information creation process of calculating a total number of emergency
stop groups based on emergency stop group information in which each emergency stop
group number assigned to each emergency stop group that is determined based on a
5 range to be affected by an anomaly in each controlled device of the plurality of
controlled devices is associated with each corresponding control device of the plurality
of control devices, and creating slice information for connecting to the same number of
user plane functions (UPFs) as the total number of emergency stop groups;
a 5G connection process of registering a control device of the 5G connection
10 process itself with the 5G network, and acquiring UPF destination information, which is
destination information of the UPFs; and
a destination information acquisition process of, based on the UPF destination
information, associating each emergency stop group number with a destination UPF
without duplication of a destination UPF between the emergency stop groups, and
15 storing information in which each emergency stop group number is associated with a
destination UPF in a destination conversion table.
