[Description of operation]
Next, the operation of the present embodiment will be described with reference to FIGS.

  FIG. 3 schematically shows an example of information stored in the database file 130.

  In the database file 130, database files 131 to 13n for each network slice are stored for each network slice 111 to 11n. The database files 131 to 13n store system parameters and hardware used by the network slices 111 to 11n.

  When system parameters and hardware are commonly used in a plurality of network slices among the network slices 111 to 11n, common items of the respective network slices have the same description even if the network slices are different. Further, when the system parameters and hardware used in the network slices 111 to 11n are changed by an instruction from the O & M application 151, the contents of the database file 130 are updated.

  It should be noted that the database file 130 may describe that the system parameters and hardware are not related to any network slice 111 to 11n but only related to the administrator of the wireless access device 100.

  Further, the database file 130 also stores identification codes (denoted as terminal IDs in FIG. 4) of wireless terminals connected to the network slices 111 to 11n as will be described later.

  FIG. 4 schematically shows information stored in the log file 120.

  The log file 120 stores individual log files 121 to 12n for each network slice 111 to 11n. In the log files 121 to 12n, information such as system parameters used by the network slices 111 to 11n, hardware, wireless terminal identification codes, connection start time, and connection end time can be recorded as a history.

  In the log file 120, authentication information 1111 to 111n for accessing the log is recorded for each network slice 111 to 11n. The authentication information 1111 to 111n may be authentication information used for general authentication methods such as password authentication, fingerprint authentication, and face authentication.

  Here, a method of accessing the log file of the network slice managed by the administrator will be described with reference to FIG.

  Each administrator of the network slices 111 to 11n inputs authentication information corresponding to the network slice managed by the administrator via the network slices 111 to 11n managed by the administrator. Then, the wireless access device 100 accepts authentication information for the log file (S101).

  Next, the control unit 160 uses the authentication unit 140 to collate the authentication information received by the wireless access device 100 in step S101 with the authentication information 1111 to 111n of the log file 120 (S102).

  The authentication unit 140 permits the administrator to access the log file of the network slice in which the authentication information received by the wireless access device 100 in step S101 matches the authentication information 1111 to 111n of the log file (S103).

  By doing so, log files of network slices other than the network slice managed by the administrator cannot be accessed.

  Next, the operation of the wireless access device 100 when the call processing application 152 accepts a connection request for a wireless terminal will be described with reference to FIG.

  When the wireless access device 100 receives the connection request signal from the wireless terminal, the call processing application 152 accepts the wireless terminal connection request (S201).

  Here, the connection request signal of the wireless terminal includes information on which network slice to connect to.

  The control unit 160 refers to the database file 130 to determine which network slice 111 to 11n is used to process the wireless terminal (S202).

  Based on the determination result of step S202, the control unit 160 records the identification code of the wireless terminal, the connection start time, the connection end time, and the like in the log files 121 to 12n corresponding to the network slices 111 to 11n to which the wireless terminal is connected. (S203).

  Further, the control unit 160 records the correspondence between the identification code of the wireless terminal and the network slices 111 to 11n in the database files 131 to 13n for each network slice of the database file 130 based on the determination result (S204).

  Then, the control unit 160 wirelessly connects the wireless access device 100 and the wireless terminal based on the network slice information determined in step S202 (S205).

  As described in step S203, the log files 121 to 12n record information such as identification codes, connection start times, and connection end times of wireless terminals connected to the network slice. Based on these pieces of information, the network slice manager can perform statistical work such as obtaining information on the connection time for each wireless terminal in a certain period.

  Next, the operation of the wireless access device when the O & M application 151 issues an instruction to change a system parameter or notify a hardware failure will be described with reference to FIG.

  It is assumed that the O & M application 151 issues an instruction to change a system parameter or notify a hardware failure as follows.

  A case where the wireless access device 100 automatically changes system parameters due to a change in radio wave status or a change in the degree of congestion in the communication usage status of the wireless system used by the network slices 111 to 11n.

  Alternatively, when the wireless access device 100 detects that a hardware failure has occurred and notifies the administrator.

  Or, it may be a case where a device other than the wireless access device 100 connected to the same network as the wireless access device 100 is instructed to change a system parameter or notify a hardware failure.

  In such a case, the O & M application 151 issues an instruction to change a system parameter or notify a hardware failure (S301).

  The control unit 160 refers to the database file 130 to determine which of the network slices 111 to 11n is the system parameter to be changed or the hardware to be notified of the failure (S302).

  Then, the control unit 160 adds the changed information to the records corresponding to the network slices 111 to 11n determined in step S302 among the records of the log file 120 (S303).

  Further, the control unit 160 updates the records corresponding to the network slices 111 to 11n determined in step S302 among the records of the database file 130 with the changed information (S304).

  After that, the control unit 160 changes the system parameters of the target network slice and notifies the hardware failure to the outside (S305).

  As described above, the wireless access device 100 allows only the administrator who uses the network slice to access the log file of the network slice to be used without providing a separate device for controlling the wireless access device 100. To do.

  The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments, and can be expanded or modified as follows.
