[0035] <Processing> An example of processing of the mobile communication system 1 according to the embodiment will be described with reference to Fig. 4 to Fig. 6. Fig. 4 is a sequence diagram showing an example of processing of the mobile communication system 1 according to the embodiment. Fig. 5 is a diagram showing an example of data recorded in a virtual mobile network operator DB (Data Base) 501 according to the embodiment. Fig. 6 is a diagram showing an example of data recorded in a resource DB 601 according to the embodiment.

[0036] In step S101, the other operator device 60 of the virtual mobile telecommunications carrier transmits a lease request for resources of the mobile communication network N1 to the control device 10, for example, by using an API (Application Programming Interface) provided by the mobile telecommunications carrier. Here, the other operator device 60 may determine the resources to be leased, for example, based on the traffic volume of communications using the mobile communication network N1 by the subscriber of the virtual mobile telecommunications carrier. In this case, the other operator device 60 may request the lease of more resources as the traffic volume increases, and may request the lease of fewer resources as the traffic volume decreases. In addition, the other operator device 60 may request the lease of resources designated by the administrator (operator) of the virtual mobile telecommunications carrier, for example, in response to an operation by the administrator.

[0037] The lease request may include, for example, identification information (virtual mobile communications carrier ID) of the virtual mobile communications carrier operating the other carrier device 60, resource contents (for example, information indicating QoS such as priority and bandwidth), and lease expiration information. The lease request may also include, for example, parameters defined in various standardizations such as the following. This allows, for example, the virtual mobile communications carrier to specify the network resources to be leased (contents of configuration changes to the mobile communications network N1). -IETF RFC8466 "A YANG Data Model for Layer 2 Virtual Private Network (L2VPN) Service Delivery" (https: / / datatracker.ietf.org / doc / rfc8466 / ) -IETF rfc8049 "YANG Data Model for L3VPN Service Delivery" (https: / / datatracker.ietf.org / doc / rfc8049 / ) -GSMA "Generic Network Slice Template" (https: / / www.gsma.com / newsroom / resources / ng-116-generic-network-slice-template-v4-0 / )

[0038] Next, the control unit 12 of the control device 10 refers to the virtual mobile network operator DB 501 and the resource DB 601 to determine whether the received lease request is permitted or not (step S102). This makes it possible to determine, for example, whether the virtual mobile network operator has the authority to lease resources. In addition, for example, resource allocation between a plurality of virtual mobile network operators and mobile network operators can be appropriately set (adjusted). The virtual mobile network operator DB 501 and the resource DB 601 may be stored in a storage device inside the control device 10, or may be stored in a device outside the control device 10.

[0039] 5, the resource ID of a resource that can be leased is recorded in association with the virtual mobile network operator ID in the virtual mobile network operator DB 501. The data in the virtual mobile network operator DB 501 may be registered by an administrator of the mobile network operator, for example, when a contract is made between the mobile network operator and the virtual mobile network operator.

[0040] In the example of FIG. 6, the resource DB 601 records resource contents (QoS, Quality of Service), the ID of the operator using the resource, and the lease period in association with the resource ID. The resource ID is identification information of the resource of the mobile communication network N1 operated by the mobile communication operator. The resource of the mobile communication network N1 may be, for example, a network slice in which a physical network is divided into a plurality of virtual independent logical networks by network slicing. The resource contents include, for example, information indicating QoS such as priority and bandwidth. The ID of the operator using the resource is identification information of the virtual mobile communication operator or mobile communication operator using the resource. If no data is stored (NULL) in the field of the ID of the operator using the resource, it indicates that the resource is not currently leased to any virtual mobile communication operator and is not used by the mobile communication operator itself. The lease period indicates the date and time when the period during which the resource is assigned to the operator ends.

[0041] The control device 10 may first extract, from the resource DB 601 in Fig. 6, resource IDs of one or more resources that match the resource content specified in a lease request from a certain mobile virtual network operator and are not currently being used by any operator. The control device 10 may then determine whether or not the extracted resource ID is registered in the mobile virtual network operator DB 501 in Fig. 5 as a resource that can be leased to the mobile virtual network operator. If the extracted resource ID is not registered, the control device 10 transmits an error response to the other operator device 60 and ends the process. On the other hand, if the resource ID is registered, the requested resource can be leased, and the control device 10 executes the following process.

[0042] An example of a process for determining the resource lease fee, the lease destination, etc. will be described below. The control device 10 may execute the following processes in appropriate combination.

[0043] (Example of determining lease payments) The control device 10 may determine the fee (lease fee) for the lease based on the time period of the period for leasing the resource requested by the virtual mobile communication operator. This allows the lease fee to be determined more appropriately. In this case, the control device 10 may be preset with information on the unit price per predetermined time (e.g., one minute) for each time period. The control device 10 may set, for example, the period from the current time to the lease expiration date as the period for leasing the resource (lease period). The control device 10 may calculate the total amount of the unit prices for each predetermined time period included in the lease period as the lease fee. This allows the control device 10 to set a higher lease fee for a time period when traffic (communication volume) is expected to be relatively high, such as at night, and a lower lease fee for a time period when traffic (communication volume) is expected to be relatively low, such as before dawn.

[0044] The control device 10 may also determine the lease fee for the resource requested by the virtual mobile network operator based on the availability of resources in the mobile communication network N1. This allows the lease fee to be determined more appropriately. In this case, the control device 10 may first refer to the resource DB 601 and calculate the total value of the bandwidth of the resources of the priority level requested by the virtual mobile network operator that are not currently being used by any operator. The control device 10 may then determine a first coefficient for the lease fee to be a larger value as the calculated total value decreases. The control device 10 may then calculate the lease fee as an amount obtained by multiplying the unit price of each predetermined time period included in the lease period by the first coefficient, for example. This allows the control device 10 to set the lease fee higher when the availability of resources is relatively low, and set the lease fee lower when the availability of resources is relatively high.

[0045] The control device 10 may also determine the lease fee for the resource requested by the virtual mobile communication carrier based on the ratio of the resource leased to the virtual mobile communication carrier among the resources of the mobile communication network N1. This allows the resource to be leased more appropriately. In this case, the control device 10 may first refer to the resource DB 601 and calculate the total value of the bandwidth of the resource not leased to the virtual mobile communication carrier among the resources of the priority level requested by the virtual mobile communication carrier. The control device 10 may then determine the second coefficient related to the lease fee to be a smaller value as the calculated total value decreases. The control device 10 may then calculate the lease fee as, for example, the total amount obtained by multiplying the unit price of each predetermined time included in the lease period by the second coefficient. This allows the control device 10 to, for example, set the lease fee higher when the resource lease is relatively large, and set the lease fee lower when the resource lease is relatively small. This allows the lease fee to be reduced when the resource lease to the virtual mobile communication carrier is small, thereby revitalizing the business of the virtual mobile communication carrier.

[0046] (Example of deciding on a lease) When the control device 10 is requested to lease the same resource by a plurality of mobile virtual network operators, the control device 10 may determine an operator to lease the resource based on the bid amount from each operator. This allows, for example, appropriate leasing. In this case, the control device 10 may transmit a bid request including, for example, a bid ID, which is bid identification information, lease contents, and lease period information, to the other operator device 60 of each operator. Then, each other operator device 60 may return a bid response including the bid ID, mobile virtual network operator ID, and bid amount to the control device 10. Then, the control device 10 may determine the operator with the highest bid amount as the lease destination. In this case, the control device 10 may determine the second highest bid amount (second price) as the lease fee. This allows the lease fee to be determined more appropriately.

[0047] Furthermore, when the control device 10 is requested by a plurality of mobile virtual network operators to lease the same resource, the control device 10 may determine the operator to which the resource is to be leased based on the lease records with each operator. This allows, for example, appropriate leasing. In this case, the control device 10 may record, for example, for each priority level of the resource leased to each operator, the integrated value of the bandwidth leased in a predetermined period (for example, one month) and the lease period as the lease record value. Then, the control device 10 may determine, as the lease destination, the operator with the lowest lease record value for the resource of the priority level requested by each operator among the operators with the same conditions such as the bid amount. This allows, for example, the operators to lease resources equally.

[0048] Furthermore, when the control device 10 is requested to lease the same resource from a plurality of mobile virtual network operators, the control device 10 may determine the operator to lease the resource based on the number of subscribers of each operator (the number of users who have contracts with the mobile virtual network operator). This allows, for example, appropriate leasing. In this case, the control device 10 may determine, as the lease destination, the operator with the largest number of subscribers among the operators with the same conditions such as bid amount.

[0049] Furthermore, when the control device 10 is requested to lease the same resource by a plurality of mobile virtual network operators, the control device 10 may determine the operator to lease the resource based on the number of subscribers (the number of terminals 40) present in the range of the base station 30 of the mobile communication network N1 among the subscribers of each operator. This allows appropriate leasing to be performed even in cases where an operator has a relatively large number of subscribers due to a contract such as free basic fee, but the number of subscribers who actually use the terminals 40 is relatively small.

[0050] Furthermore, when the control device 10 is requested to lease the same resource by a plurality of mobile virtual network operators, the control device 10 may determine the operator to lease the resource based on the number of subscribers (the number of terminals 40) communicating through the mobile communication network N1 among the subscribers of each operator. This allows appropriate leasing to be performed even in cases where an operator has a relatively large number of subscribers due to a contract such as free basic fee, but the number of subscribers who actually use the terminals 40 is relatively small.

[0051] Next, the transmitter 13 of the control device 10 transmits a control command to the relay device 20 to lease the resource to be leased to the virtual mobile network operator (step S103). Here, the control device 10 may cause the relay device 20 to generate a network slice of an IP layer such as segment routing (SRv6) using an IPv6 extension header, MPLS (Multi-Protocol Label Switching), VPN (Virtual Private Network), or VLAN (Virtual LAN). The control device 10 may also cause the relay device 20 to generate a network slice by FlexE (Flex Ethernet) standardized by OIF (Optical Internetworking Forum). In FlexE, for example, slices are generated by dividing the wavelength of an optical signal into physically fine bands (physical resources).

[0052] Next, the relay device 20 performs settings related to relaying based on the received control command (step S104). Next, the relay device 20 relays packets and the like based on the settings (step S105). Here, when the relay device 20 receives a packet transmitted from the terminal 40 and when it receives a packet transmitted to the terminal 40, it may extract identification information (e.g., International Mobile Subscriber Identity (IMSI) and the like) of the terminal 40 contained in the packet. Then, the relay device 20 may determine the virtual mobile communications carrier or the like with which the user of the terminal 40 has a contract, for example, by referring to a subscriber management database (e.g., Home Location Register (HLR) / Home Subscriber Server (HSS)). Then, the relay device 20 may transfer (relay) the packet using resources (e.g., slices) currently assigned to the virtual mobile communications carrier or the like with which the user of the terminal 40 has a contract.

[0053] <Modification> The control device 10 may be a device contained in one housing, but the control device 10 of the present disclosure is not limited to this. The control device 10 may be realized by cloud computing configured with one or more computers, for example. The control device 10 may also be a server or edge server that realizes network virtualization (Network Functions Virtualization, NFV). At least a part of the processing of the control device 10 may be executed by the relay device 20 or the base station 30. Such a control device 10 is also included in the examples of the "control device" of the present disclosure.
