  FIG. 1 is a diagram showing a relationship between a communication system (slice management system) including the SMF 100 of this embodiment and its resources. FIG. 1A is a diagram illustrating a system configuration of a communication system. This communication system includes SMF 100, MANO 150, wireless LAN controller 200, SSF 300, gateway group 400, authentication server 500, and subscriber information DB 600. This communication system can communicate with a wireless terminal 700 such as a smartphone or a tablet terminal via an AP (access point) 800 of a wireless LAN. The router / gateway group 400 constitutes a wired network. This wired network constitutes a slice that is a virtualized network according to the management of MANO 150.

  The wireless LAN controller 200 assigns resources in the wireless section to the AP 800. Here, resources according to the service type to be received by wireless terminal 700 are allocated. The SMF 100 determines a slice according to the service type transmitted from the wireless LAN controller 200, and then changes the resource of the slice according to the usage status of the radio resource for each service type. That is, the SMF 100 requests the MANO 150 to change the slice resource, and the MANO 150 changes the slice resource set in the gateway group 400 in response to the request.

When assigning or changing a slice resource, the slice resource stored in the NFVO and VIM is assigned or changed, and the assigned or changed resource is reflected in the hardware resource.

  FIG. 1B is a schematic diagram showing resource allocation between the wireless section and the wired section. As shown in the figure, the wireless terminal 700 can perform wireless LAN (for example, conforming to IEEE 802.11ac) communication with the access point 800 (wireless section). In addition, the wireless terminal 700 is connected to a wired network (wired section) composed of the gateway group 400 via a wireless LAN. As described above, a plurality of slices are constructed on the wired network. The slice is associated with each service type, and the wireless terminal 700 can receive a service according to the service type via the slice.

  As shown in FIG. 1B, the wireless resource in the wireless section and the wired resource in the wired section are set in association with each other. For example, when the wireless terminal 700a receives a broadband service (video distribution or the like), wireless resources that can provide the service are allocated by the wireless LAN controller 200. Also, the SMF 100 assigns wired resources that enable providing broadband service to the slices according to the radio resources.

  Similarly, in the wireless terminals 700b and 700c, if a wireless resource is assigned with a low-delay service such as AR (Augmented Reality) or VoIP (Voice Over IP) or an IoT (Internet of Thing) service. The wired resource corresponding to the wireless resource is assigned to the slice.

  The configurations of the SMF 100 and the wireless LAN controller 200 in such a communication system will be described. FIG. 2 is a functional block diagram showing functional configurations of the SMF 100 and the wireless LAN controller 200. Hereinafter, functions of each device will be described.

  First, the wireless LAN controller 200 will be described. The wireless LAN controller 200 includes a service type acquisition unit 201, a wireless resource policy table 202, a wireless resource allocation unit 203, a totaling processing unit 204, a totaling table 205, an information notification unit 206, and a slice allocation unit 207. Yes.

  The service type acquisition unit 201 is a part that acquires a service type indicating a service to be provided by the wireless terminal 700, and acquires the service type from the wireless terminal 700 using ANQP (Access Network Query Protocol). Here, the service type includes a broadband service that requires high-speed and large-capacity communication such as moving image distribution, a low-delay service that requires high-speed communication such as VoIP, and an IoT service that allows delay such as transmission of sensor data.

  The radio resource policy table 202 stores radio resources and MAC schedules in association with each service type.

  FIG. 3 is a diagram illustrating a specific example of the radio resource policy table 202. As shown in FIG. 3, the service type to be provided, the radio resource, and the MAC schedule are stored in association with each other. The radio resource defines the number of streams, the frequency band, and the MCS (modulation scheme), and the MAC schedule defines the band occupation time (TXOP value) and the priority (EDCA value).

  The radio resource allocation unit 203 is a part that refers to the radio resource policy table 202 and determines a radio resource and a MAC schedule corresponding to the service type. The radio resource allocation unit 203 notifies the determined radio resource to the radio terminal 700, thereby enabling radio communication in the radio section using the determined radio resource.

  The aggregation processing unit 204 is a part that aggregates the number of wireless terminals 700 connected to each AP 800 for each service type. The aggregation processing unit 204 can perform aggregation processing based on signals from each AP 800.

  The tabulation table 205 is a part that stores the number of wireless terminals 700 for each service type tabulated by the tabulation processing unit 204. FIG. 4 is a diagram illustrating a specific example of the aggregation table 205. As illustrated in FIG. 4, the aggregation table 205 stores an aggregation result in which the ID of the AP 800, the service type, and the number of wireless terminals 700 are associated with each other.

  The information notification unit 206 is a part that notifies the SMF 100 of the number of wireless terminals 700 for each service type in each AP 700 and the priority of the wireless section, which are the totaling results stored in the totaling table 205. This notification process is performed periodically.

  As described above, the wireless LAN controller 200 can allocate wireless resources to the wireless terminal 700 and the AP 800.

  Next, the SMF 100 will be described. The SMF 100 includes a slice allocation unit 101, a wired resource management table 102, a priority management table 103, a slice selection policy table 104, and a slice notification unit 105.

  The slice allocation unit 101 is a part that determines a slice corresponding to a service type based on the service type notified from the wireless LAN controller 200 and the slice selection policy table 104 when determining a slice corresponding to the service type. is there. The slice selection policy table 104 is associated with a slice corresponding to the service type, and by referring to this, a slice corresponding to the service type can be determined.

  Further, the slice allocation unit 101 can change the resource of the slice after the slice is determined. That is, the slice allocation unit 101 calculates the wired resource in the slice corresponding to the service type, which is in the usage state of the wireless resource, based on the service type notified from the wireless LAN controller 200 and the aggregation result. The calculated wired resource is stored in the wired resource management table 102.

For example, based on the number of wireless terminals for each service type in each AP 700 notified from the wireless LAN controller 200, the slice allocation unit 101 determines the number of connected APs that is one or more APs for each service type. Based on this, the wired resource of the slice (wired section for each service type) is calculated. The bandwidth of this wired resource is calculated for each slice by the following formula.
(Number of APs × radio resource bandwidth [bps] × statistical multiple effect rate) + margin [bps]
Here, the number of APs is the number of APs to which one or more wireless terminals are connected to the corresponding service. The statistical multiple effect rate and the margin are predetermined fixed values and are values set by the operator when the SMF 100 is set. The radio resource band is a radio resource band corresponding to the service type.

  In addition, the slice allocation unit 101 calculates a wired resource (priority) for each slice. The priority among the wired resources is determined based on the priority (EDCA value) of the wireless section transmitted from the wireless LAN controller 200, and the EDCA value (wireless) and DSCP value (wired) set in the priority management table 103. ) Mapping table.

  The wired resource calculated in this way is stored in the wired resource management table 102. FIG. 5 is a diagram illustrating a specific example of the wired resource management table 102. As shown in FIG. 5, wired resources and server resources are allocated for each slice ID. In FIG. 5, slice 1 is assigned as bandwidth: xxxx [Gbps], priority: medium, resource securing period: BB: BB: BB. The bandwidth and the priority are generated as described above, and the resource securing period is a predetermined fixed value.

  The server resource is allocated so that the server resource is proportional to the wired resource. In other words, as the bandwidth of wired resources is wider and the priority is higher, the bandwidth and priority are given to the overall resources of the server so that the number of assigned CPUs, memory (work area) and storage (storage capacity) increase. It is calculated by multiplying a ratio determined according to the degree.

  Based on the wired resource management table 102, the slice allocation unit 101 requests the MANO 150 to change the resource allocation of each slice. Based on this request, the MANO 150 executes resource allocation processing for each slice.

  The priority management table 103 is a part that stores the priority of wireless resources and the priority of wired resources in association with each other. For example, the priority of the radio resource is represented by an EDCA value, and the wired resource is represented by a DSCP value.

  The slice selection policy table 104 is a part that stores a service type that the wireless terminal 700 is to receive and a corresponding slice. FIG. 6 is a diagram showing a specific example thereof. As shown in FIG. 6, the slice ID that is the connection destination slice and the service type are stored in association with each other.

  The slice notification unit 105 is a part that notifies the wireless LAN controller 200 of a slice corresponding to the service type determined by the slice allocation unit 101. The wireless LAN controller 200 manages service types and slices, thereby enabling slice selection processing regardless of hardware mapping.

  Next, the operation of the communication system including the SMF 100 of this embodiment will be described. FIG. 7 is a sequence diagram showing the operation of the communication system of the present embodiment.

  A service type notification is transmitted from the wireless terminal 700 to the wireless LAN controller 200 (S101).

  In the wireless LAN controller 200, when the service type is acquired by the service type acquisition unit 201, the radio resource allocation unit 203 determines the radio resource / MAC schedule according to the radio resource policy table 202 (S102). The determined radio resource and MAC schedule are notified to the radio terminal 700 (S103), and AP connection processing is performed according to the notified radio resource and MAC schedule (S104).

  In the wireless LAN controller 200, the total processing unit 204 totals the number of wireless terminals for each service type in each AP 700 (S105). Then, the information notification unit 206 periodically transmits the aggregation result for each service type to the SMF 100 (S106). The wireless LAN controller 200 also transmits information indicating the priority in the wireless section.

  When the SMF 100 receives the service type and the aggregation result, the slice allocation unit 101 selects a slice corresponding to the service type. Then, the number of connected APs of the AP 800 to which one or more wireless terminals 700 are connected is calculated, and the wired resource is calculated based on the number of connected APs. Also, according to the priority management table 103, the priority of the slice corresponding to the priority in the wireless section transmitted from the wireless LAN controller 200 is determined as one parameter of the wired resource (S107).

  Then, the slice allocation unit 101 transmits the slice ID of the selected slice and the calculated wired resource to the MANO 150 (S108).

  In MANO 150, a slice resource change request is made to the gateway group 400 constituting the slice specified by the slice ID (S109). The SSF 300 stores slices and service types in association with each other, and the SSF 300 can perform slice switching processing according to the service types (S110).

  Next, the function and effect of the SMF 100 of this embodiment will be described. The SMF 100 of this embodiment functions as a slice management device that manages slices that are virtualized networks generated on the network infrastructure. In this SMF 100, the slice allocating unit 101 wired to a slice set for each service type based on the usage status of radio resources in the radio section associated with the service type used by the radio terminal 700. Assign resources.

  In this SMF 100, by allocating wired resources to slices set for each service type based on the usage status of radio resources in the service type, excessive allocation of wired resources to slices is prevented. It is possible to prevent a reduction in accommodation efficiency.

  Also, the wireless LAN usage status is acquired by the wireless LAN controller 200 here. That is, the wireless LAN controller 200 counts the number of wireless terminals 700 connected to the AP 800 for each AP 800 that is a base station performing wireless access with one or a plurality of wireless terminals 700. In the SMF 100, the slice allocation unit 101 receives the number of wireless terminals 700 for each AP 800 from the wireless LAN controller 200, and based on the received number, the number of APs 800 connected to at least one wireless terminal 700 is connected. The number of connected APs is calculated. Then, the slice assignment unit 101 calculates the wired resource of the slice based on the number of connected APs.

  As a result, since the resource of the slice in the wired section is determined based on the number of connected APs in the wireless section, it is possible to calculate the resource of the slice according to the usage status of the wireless section.

  In addition, the SMF 100 according to the present embodiment includes a priority management table 103 that associates priorities in radio sections with priorities in slices. The slice allocation unit 101 refers to the priority management table 103 and determines the slice priority corresponding to the priority of the wireless section transmitted from the wireless LAN controller 200, thereby determining the resources of the slice of the wired section. can do.

  The communication system including the SMF 100 according to the present embodiment includes a wireless LAN controller 200 that is a wireless section management device for setting wireless resources of a wireless terminal, and the SMF 100. The wireless LAN controller 200 can acquire a service type from the wireless terminal 700 and allocate wireless resources in a wireless section based on the service type. Then, the SMF 100 can determine the resources in the wired section using the wireless resources allocated by the wireless LAN controller 200.

  Where the designation "first", "second", etc. is used herein, any reference to that element does not generally limit the amount or order of those elements. These designations can be used herein as a convenient way to distinguish between two or more elements. Thus, a reference to the first and second elements does not mean that only two elements can be employed there, or that in some way the first element must precede the second element.

  As long as “include”, “comprising”, and variations thereof, are used in the specification or claims, these terms are similar to the term “comprising”. It is intended to be comprehensive. Furthermore, the term “or” as used herein or in the claims is not intended to be an exclusive OR.

  In this specification, a plurality of devices are also included unless there is only one device that is clearly present in context or technically.

  Throughout this disclosure, the plural is included unless the context clearly indicates one.
