Abstract

In a business wireless system, a group including a plurality of terminal devices is formed and communication is performed by using at least one base station device to assign a channel to each group. A transmission unit uses a channel assigned by the base station device to a first group for transmission. An authentication processing unit authenticates a user using the terminal device. A selection unit selects one of a second group that only the terminal devices for which the authentication process is completed can subscribe to, and the first group, when the authentication process is completed. When the second group is selected, the transmission unit the channel assigned by the base station device to the second group for transmission.

Claims

1. A terminal device used in a communication system where a group including a plurality of terminal devices is formed and communication is performed by using at least one base station device to assign a channel to each group, the terminal device comprising:

a transmission unit that uses a channel assigned by the base station device to a first group for transmission;

an authentication processing unit that performs an authentication process for authenticating a user using the terminal device; and

a selection unit that selects one of a second group that only the terminal devices for which the authentication process is completed can subscribe to, and the first group, when the authentication process is completed, wherein

when the second group is selected in the selection unit, the transmission unit uses the channel assigned by the base station device to the second group for transmission.

2. The terminal device according to claim 1, further comprising:

a reception unit that uses the channels assigned by the base station device to the first group and the second group for reception when the authentication process is completed in the authentication processing unit, wherein

selection in the selection unit is made when a signal is transmitted from the transmission unit, and

when the second group is selected in the selection unit, the transmission unit uses the channel assigned by the base station device to the second group for transmission, and, when the first group is selected in the selection unit, the transmission unit uses the channel assigned by the base station device to the first group for transmission.

3. The terminal device according to claim 1, further comprising:

a reception unit that uses the channel assigned by the base station device to the second group for reception when the second group is selected in the selection unit and uses the channel assigned by the base station device to the first group for reception when the first group is selected in the selection unit, and

when the second group is selected in the selection unit, the transmission unit uses the channel assigned by the base station device to the second group for transmission, and, when the first group is selected in the selection unit, the transmission unit uses the channel assigned by the base station device to the first group for transmission.

4. The terminal device according to claim 1, further comprising:

a notification unit that outputs information related to the first group and the second group selectable in the selection unit, wherein

the notification unit outputs a list of other terminal devices included in the first group or the second group.

5. The terminal device according to claim 2, further comprising:

a notification unit that outputs information related to the first group and the second group selectable in the selection unit, wherein

the notification unit outputs a list of other terminal devices included in the first group and in the second group.

6. The terminal device according to claim 3, further comprising:

a notification unit that outputs information related to the first group and the second group selectable in the selection unit, wherein

the notification unit outputs a list of other terminal devices included in the first group and in the second group.

7. A management device used in a communication system where a group including a plurality of terminal devices is formed and communication is performed by using at least one base station device to assign a channel to each group, the management device comprising:

a first management unit that manages a plurality of terminal devices included in a first group; and

a second management unit that manages a plurality of terminal devices included in a second group that only the terminals for which an authentication process for authenticating a user using the terminal device is completed can subscribe to.

8. A non-transitory computer-readable recording medium having embedded thereon a program for a terminal device used in a communication system where a group including a plurality of terminal devices is formed and communication is performed by using at least one base station device to assign a channel to each group,

the program comprising:

using a channel assigned by the base station device to a first group for transmission;

performing an authentication process for authenticating a user using the terminal device; and

selecting one of a second group that only the terminal devices for which the authentication process is completed can subscribe to, and the first group, when the authentication process is completed; and

using, when the second group is selected in the selection unit, the channel assigned by the base station device to the second group for transmission.

9. A non-transitory computer-readable recording medium having embedded thereon a program for a management device used in a communication system where a group including a plurality of terminal devices is formed and communication is performed by using at least one base station device to assign a channel to each group,

the program comprising:

managing a plurality of terminal devices included in a first group; and

managing a plurality of terminal devices included in a second group that only the terminals for which an authentication process for authenticating a user using the terminal device is completed can subscribe to.
