It should be noted that the reference numerals in the drawings attached to this outline are added for convenience of each element as an example for facilitating understanding, and the description of this outline is not intended to limit the invention in any way.

<First embodiment>
A first embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a configuration example of a communication system according to the first embodiment. FIG. 1 illustrates a communication system of LTE (Long Term Evolution), but the communication system of the present invention is not limited to the example of FIG. For example, the present invention relates to GPRS (General Packet Radio Service), UMTS (Universal Mobile Telecommunication System), WiMAX (Worldwide Interoperability for Microwave, etc.).

  In FIG. 1, a communication system according to the first embodiment includes a mobile phone, a PC (Personal Computer), a mobile router, a smart device (for example, a smart meter for monitoring home power consumption, a smart TV, a wearable terminal), and an M2M ( A terminal 1 such as a Machine to Machine device is included. The M2M device includes, for example, an industrial device, a car, a healthcare device, a home appliance, and the like in addition to the above devices.

  The communication system according to the first embodiment includes a legacy network and a MVNO (Mobile Virtual Network Operator) network. The legacy network and the MVNO network are backbone networks such as EPC (Evolved Packet Core). The legacy network and the MVNO network are backbone networks for the terminal 1 to communicate with an external network such as the Internet via the base station 2.

Although the communication system illustrated in FIG. 1 includes one legacy network, the number of legacy networks included in the communication network is not limited to one and may be plural. Further, the communication system illustrated in FIG. 1 includes one MVNO network, but the number of MVNO networks included in the communication system is not limited to one, and may be plural.
The legacy network to be managed is managed by, for example, a mobile network operator (MNO: Mobile Network Operator) that manages the communication network. The MVNO network is managed by, for example, a virtual mobile communication carrier (MVNO).

  The MNO is, for example, a communication carrier licensed for a wireless band (frequency) used for wireless communication between the terminal 1 and the base station 2. The MVNO is, for example, a communication carrier that has not received a license for a wireless band (frequency) used for wireless communication between the terminal 1 and the base station 2.

  The MNO, for example, lends a part or all of a communication network managed by the MNO to the MVNO. The MNO is, for example, a network node (for example, a base station (eNB) 2, an SGW (Serving Gateway) 3, an PGW (PDN Gateway) 4, an MME (Mobile Management Entity) 5, which provides a communication service to the MVNO. Lend). The MNO lends, for example, a wireless band (frequency) licensed to the MNO to the MVNO.

  The MVNO provides a communication service using, for example, a wireless band (frequency) licensed by the MNO, that is, a licensed band. The MVNO provides a communication service by borrowing a part or all of a licensed band managed by the MNO. The subscriber terminal of the MVNO performs wireless communication with the base station 2 using, for example, a licensed band borrowed from the MNO. Note that the MVNO subscriber terminal may perform wireless communication with the base station 2 using the unlicensed band frequency band.

  The MVNO provides a communication service to a subscriber terminal of the MVNO, for example, using a network node managed by the MNO. The MVNO provides a communication service, for example, by borrowing some or all of the network nodes managed by the MNO.

  The legacy network includes a plurality of network nodes (for example, a base station (eNB) 2, an SGW 3, a PGW 4, and an MME 5) for providing a communication service to the terminal 1. Each network node is, for example, a communication device having a predetermined communication function.

  The terminal 1 is connected to, for example, the base station 2 and accesses a network such as the Internet via the SGW 3 and the PGW 4.

  The communication system of FIG. 1 may include networks other than the legacy network and the MVNO network. Further, the legacy network and the MVNO network may each include a plurality of types of networks. For example, the legacy network and the MVNO network may each include a plurality of types of networks such as an LTE network, a GPRS network, and a UMTS network.

  Each network node illustrated in FIG. 1 executes a predetermined signal processing. Each network node includes, for example, the following functions related to signal processing.

PGW4:
-Packet processing function (User-Plane function)
A function for managing a charging state according to communication (PCEF: Policy and Charge)
ing Enforcement Function)
-Function to control policies such as QoS (PCRF: Policy and Chargi)
ng Rule Function)

SGW3:
-Packet processing function (User-Plane function)
-Function for processing control signaling (C-Plane function)
Lawful Interception (LI: Lawful Interception) for intercepting communications
function

MME5:
-Function for processing control signaling (C-Plane function)
-Function to manage subscriber information of the communication system in cooperation with HSS (Home Subscriber Server)

  The MVNO network includes a plurality of network nodes (for example, SGW3A, PGW4A, MME5A) for providing a communication service to the terminal 1. The function of each network node (eg, SGW3A, PGW4A, MME5A, etc.) included in the MVNO network is the same as the function of each network node (eg, SGW3, PGW4, MME5) included in the legacy network. Detailed description is omitted.

  In the communication system illustrated in FIG. 1, the base station 2 is managed by an MNO that manages a legacy network. In the first embodiment, the base station 2 distributes communication traffic between the legacy network and the MVNO network. That is, the communication traffic is distributed to a plurality of networks (for example, a legacy network and an MVNO network) constituting a backbone of a wireless network between the terminal 1 and the base station 2. That is, for example, even when the terminal 1 cannot access a wireless network such as a wireless LAN, communication traffic is offloaded in the backbone network. Therefore, the base station 2 can execute traffic offload regardless of the radio environment of the terminal.

  FIG. 2 shows a configuration example of the base station 2. The base station 2 includes an identification unit 20 and a network switching unit 21.

  The identification unit 20 identifies a network corresponding to the terminal 1. The identification unit 20 identifies a network corresponding to the terminal 1 from a plurality of networks including a network node of a legacy network and an MVNO network. Further, the identification unit 20 may identify a network node included in the network corresponding to the terminal 1. The identification unit 20 may identify the type of communication traffic and the attribute / type of the terminal 1. In this case, the identification unit 20 selects a network corresponding to the identified communication traffic or the terminal 1 from a plurality of networks including the legacy network and the MVNO network. The identification unit 20 may select a network node corresponding to the identified communication traffic or the terminal 1 from a plurality of network nodes including a network node of the legacy network and a network node of the MVNO network.

  The identification unit 20 can identify an attribute of communication traffic or an attribute of the terminal 1 based on predetermined information, for example. The identification unit 20 identifies communication traffic to be processed in the MVNO network, for example, based on predetermined information. The identification unit 20 may, for example, identify whether the terminal 1 is a terminal 1 having an attribute to be processed in the MVNO network, based on predetermined information.

  For example, the identification unit 20 may identify that the terminal 1 is a terminal corresponding to a predetermined network. The identification unit 20 identifies, for example, the terminal 1 is a terminal corresponding to the MVNO network. The identification unit 20 may identify, for example, that the terminal 1 is a terminal corresponding to a predetermined mobile communication carrier (MNO). In this case, the identification unit 20 identifies that the terminal 1 is a terminal corresponding to MVNO. Further, the identification unit 20 may identify, for example, that the terminal 1 is a terminal contracted with a predetermined MNO. The identification unit 20 may identify, for example, that the terminal 1 is a terminal contracted with the MVNO.

  For example, when the communication system includes a plurality of MVNO networks, the identification unit 20 may select an MVNO network corresponding to the terminal 1 from the plurality of MVNO networks based on predetermined information.

  The identification unit 20 can identify the terminal 1 or a network corresponding to the communication traffic of the terminal 1 based on predetermined information included in a connection request from the terminal 1, for example. The identification unit 20 identifies, for example, the terminal 1 or a network corresponding to the communication traffic of the terminal 1 based on information capable of specifying the network corresponding to the terminal 1.

  The identification unit 20 identifies the terminal 1 or a network corresponding to the communication traffic of the terminal 1 as an MVNO, for example, based on information indicating that the terminal 1 is a terminal corresponding to the MVNO network. The identification unit 20 identifies the terminal 1 and the network corresponding to the communication traffic of the terminal 1 as the MVNO (or the MNO) based on, for example, information specifying the MVNO (or the MNO) to which the terminal 1 contracts. May be. The identification unit 20 identifies the terminal 1 or the network corresponding to the communication traffic of the terminal 1 with the MVNO (or the MNO) based on information indicating that the terminal 1 has a contract with the MVNO (or the MNO), for example. May be identified.

  The identification unit 20 can identify the terminal 1 or a network corresponding to the communication traffic of the terminal 1 based on, for example, a PLMN (Public Land Mobile Network) included in the connection request from the terminal 1. The PLMN is a network identification number of a mobile communication carrier (or virtual mobile communication carrier) or a communication network (legacy network or MVNO network), and is assigned, for example, for each MNO (or MVNO) or each communication network. Can be

  The PLMN is included in “RRC Connection Setup Request” from the terminal 1, for example. The PLMN is included in, for example, “RRC Connection Setup Complete” from the terminal 1. The identification unit 20 can identify the terminal 1 or a network corresponding to the communication traffic of the terminal 1 based on, for example, the PLMN included in “RRC Connection Setup Complete” from the terminal 1.

  The network switching unit 21 switches the network to which the terminal 1 connects, according to the identification result of the identification unit 20. The network switching unit 21 switches the transfer path of the communication traffic such that the communication traffic regarding the terminal 1 passes through the identified network (for example, the legacy network or the MVNO network). The network switching unit 21 transfers the communication traffic of the terminal 1 to the network identified as corresponding to the terminal 1. The network switching unit 21 transfers, for example, communication traffic of the specific terminal 1 identified by the identification unit 20 as corresponding to the MVNO network to the MVNO network.

  The network switching unit 21 manages network nodes of a legacy network (eg, SGW3, PGW4, MME5) and network nodes of an MVNO network (eg, SGW3A, PGW4A, MME5A) separately from each other. The network switching unit 21 manages, for example, identification information on a network node of the legacy network (for example, an address of the network node) and identification information on a network node of the MVNO network separately from each other. Further, the network switching unit 21 may, for example, associate a flag indicating whether or not the network node is a network node included in the MVNO network (or the legacy network) with the identification information of each network node. The network switching unit 21 can transmit, for example, communication traffic to be transferred to the MVNO network to a network node on the MVNO network.

  The network switching unit 21 transfers, for example, communication traffic of the terminal 1 to the identified communication network. The network switching unit 21 may transfer the communication traffic of the terminal 1 to a predetermined communication network, for example, according to the identification result of the identification unit 20. The network switching unit 21 transfers, for example, communication traffic of the terminal 1 to a legacy network managed by the identified MNO. The network switching unit 21 may transfer the communication traffic of the terminal 1 to a network managed by a predetermined MNO, for example, according to the identification result of the identification unit 20.

  The identification unit 20 may identify the terminal 1 corresponding to a predetermined network, for example, based on the PLMN. The network switching unit 21 transfers, for example, communication traffic of the terminal 1 to the identified predetermined network. The identification unit 20 identifies the terminal 1 corresponding to the MVNO network (or the legacy network) based on, for example, the PLMN. The network switching unit 21 transfers the traffic of the terminal 1 identified as corresponding to the MVNO network to the MVNO network, for example.

  Note that the identification unit 20 may identify a predetermined network (legacy network or MVNO network) corresponding to the terminal 1, for example. In this case, the network switching unit transfers, for example, communication traffic from the terminal 1 to the identified predetermined network (legacy network or MVNO network).

  FIG. 2 illustrates an example in which the base station 2 has the functions of the identification unit 20 and the network switching unit 21. However, the MME 5 may have the functions of the identification unit 20 and the network switching unit 21. The MME 5 may identify the attribute / type of the terminal based on, for example, the IMSI (International Mobile Subscriber Identity). IMSI is terminal identification information.

  FIG. 3 illustrates a configuration example of the terminal 1 according to the first embodiment. As illustrated in FIG. 3, the terminal 1 includes a message generation unit 10 and a communication unit 11.

  The message generator 10 generates a message for the base station 2 to select a network. The message generator 10 generates, for example, a message including information that can specify a network corresponding to the terminal 1. The message generator 10 generates, for example, a message including information indicating that the terminal 1 is a terminal corresponding to the MVNO network (or the legacy network). The message generation unit 10 generates, for example, a message including information specifying a predetermined MNO (or MVNO) contracted by the terminal 1. The message generator 10 generates a message including information indicating that the terminal 1 has contracted with the MNO (or MVNO), for example.

  The communication unit 11 transmits the generated message to the base station 2.

  FIG. 4 is a sequence diagram illustrating an operation example of the first embodiment.

  The terminal 1 notifies the base station 2 of a request to connect to the network (S1-1). The terminal 1 notifies the base station 2 of a connection request to the network, for example, when the power is turned on or when the cellular communication function is turned on.

  The base station 2 selects a network to which the terminal 1 connects in response to a connection request from the terminal 1 (S1-2). The base station 2 selects a network corresponding to the terminal 1 from a plurality of networks including a legacy network or an MVNO network, for example. The base station 2 identifies, for example, a network corresponding to the terminal 1 and selects the identified network as a network to which the terminal 1 connects. For example, the base station 2 selects an MVNO network for the terminal 1 according to the fact that the terminal 1 that has notified the connection request is a terminal that has contracted with the MVNO.

  The base station 2 connects the terminal 1 to the selected network (S1-3). The base station 2 connects the terminal 1 to a network corresponding to the terminal 1 from a plurality of networks including a legacy network and an MVNO network.

  FIG. 5 is another configuration example of the communication system according to the first embodiment. The communication system illustrated in FIG. 5 includes, for example, a terminal 1, a base station 2, a legacy network, and an MVNO network.

  The legacy network includes, for example, an access network, the HSS 6, and the communication device 7.

  The access network includes MME5. The MME 5 processes control signaling in cooperation with the HSS 6 that manages subscriber information of the communication system.

  The HSS 6 manages subscriber information of the communication system. The HSS 6 stores, for example, information on a subscriber of the communication system, and performs authentication and authorization of the user of the terminal 1. The HSS 6 provides, for example, the location information and the IP information of the terminal 1 to another device (for example, the MME 5).

  FIG. 6 is a diagram illustrating a configuration example of the HSS 6. As illustrated in FIG. 6, the HSS 6 includes a subscriber information database 60, a control unit 61, and an interface 62.

  The subscriber information database 60 holds user information and subscriber information of the communication system. The subscriber information database 60 holds, for example, an IMSI used for identifying a user, and a Mobile Subscriber Integrated Services Digital Network Number (MSISDN) corresponding to the user's telephone number. The subscriber information database 60 holds, for example, IP Multimedia Private Identity (IMPI) and IP Multimedia Public Identity (IMPU). The subscriber information database 60 also holds information on users and subscribers.

  The subscriber information database 60 manages, for example, the IMSI of a terminal subscribed to a predetermined MNO. The subscriber information database 60 manages, for example, the IMSI of a terminal subscribed to the MNO. The subscriber information database manages, for example, the IMSI of a terminal subscribed to MVNO. For example, the subscriber information database 60 may manage, for each MNO, the IMSI of a terminal that has contracted with the MNO. The subscriber information database 60 may manage, for example, the IMSI of a terminal contracting with the MNO and the IMSI of a terminal contracting with the MVNO separately.

  The control unit 61 has a function corresponding to C-Plane. The control unit 61 transmits and receives control signaling via the interface 62. The control unit 61 executes authentication and authorization of the user of the terminal 1 with reference to the subscriber information database 60, for example. The control unit 61 provides the location information and the IP information of the terminal 1 to another device (for example, the MME 5) with reference to the subscriber information database 60, for example.

  The interface 62 is an interface for communicating with the MME 5, the communication device 7, and the like. The HSS 6 can communicate with the MME 5, the communication device 7, and the like via a predetermined protocol via the interface 62. The HSS 6 can communicate with the communication device 7 via, for example, the interface 62 using the Diameter protocol.

  The communication device 7 is a CSCF (Call Session Control Function) that provides a session control function in an IMS (IP (Internet Protocol) Multimedia Subsystem) network. The communication device 7 is, for example, an S-CSCF (Serving-CSCF) 70, a P-CSCF (Proxy-CSCF) 71, and an I-CFCF (Interrogating-CSCF) 72. Each of the S-CSCF 70, the P-CSCF 71, and the I-CFCF 72 can process a SIP (Session Initiation Protocol) signal.

  The S-CSCF 70 performs session control and user authentication using the subscriber information (user information) of the communication system obtained from the HSS 6. The S-CSCF 70 has, for example, a function of receiving a session start signal from the terminal 1, selecting an application server (AS) corresponding to a service, and relaying a SIP signal to the application server. The S-CSCF 70 has a function of executing routing based on the telephone number, for example, when the terminal 1 specifies a communication partner by a telephone number.

  The S-CSCF 70 transmits a SIP signal from an application server (AS) to an MRFC (MRF Controller) included in an MRF (Media Resource Function) for providing a media control function, for example, for media control of audio and video. Relay.

  The S-CSCF 70 transmits / receives an SIP signal to / from another network, for example, to / from an MGCF (Media Gateway Controller Function) that converts a call control protocol.

  The P-CSCF 71 is arranged at a connection point between the IMS network and the access network. The P-CSCF 71 connects to the P-GW 3, for example, when the access network is LTE (Long Term Evolution) and EPC (Evolved Packet Core). For example, when the access network is W-CDMA (Wideband CDMA (Code Division Multiple Access)), the P-CSCF 71 is connected to a GGSN (Gateway GPRS (General Packet Radio Service) Support Node). The GGSN has a function of controlling connection with an external IP (Internet Protocol) network according to a connection request from the terminal 1.

  The P-CSCF 71 relays, for example, SIP signals transmitted and received between the terminal 1, the S-CSCF 70, and the I-CSCF 72. The P-CSCF 71 executes, for example, the validity check of the SIP signal transmitted from the terminal 1 and adds information (for example, billing information) necessary for session control to the S-CSCF 70 to the SIP signal. . For example, the P-CSCF 71 notifies an application type necessary for performing QoS (Quality of Service) control in the IMS to a Policy and Charging Enforcement Function (PCRF) that provides a function of executing a policy and charging.

  The I-CSCF 72 relays, for example, a SIP signal transmitted and received between another network and the S-CSCF 70. The I-CSCF 72 selects the S-CSCF 70 according to the user information of the HSS 6 at the time of registration with the IMS network or session control, for example.

  The MVNO network includes, for example, an access network, an HSS 6A, and a communication device 7A. Since the MME 5A, the HSS 6A, and the communication device 7A included in the access network have the same configuration as the MME 5, the HSS 6, and the communication device 7 included in the legacy network, detailed description is omitted. .

  As described above, the communication system according to the first embodiment can distribute communication traffic between the legacy network and the MVNO network. That is, the communication traffic is distributed to a plurality of networks (for example, a legacy network and an MVNO network) constituting a backbone of a wireless network between the terminal 1 and the base station 2. That is, for example, even when the terminal 1 cannot access a wireless network such as a wireless LAN, communication traffic is offloaded in the backbone network. Therefore, the communication system of the first embodiment can execute traffic offload independent of the wireless environment of the terminal.

<Second embodiment>
In the second embodiment of the present invention, at least some of the functions of the network nodes included in the MVNO network are virtually operated by software or the like. Note that the technology of the second embodiment is applicable to both the first embodiment and the embodiments described below.

  In the communication system according to the second embodiment, the network nodes included in the MVNO network are virtually operated by software or the like. Therefore, the MNO that manages the MVNO network can easily and at low cost construct a network node that provides a backbone network function such as EPC by software.

  FIG. 7 illustrates a configuration example of a communication system according to the second embodiment of this invention.

  In FIG. 7, a terminal 1A is a terminal corresponding to a legacy network. The terminal 1A is, for example, a terminal that has contracted with the MNO that manages the legacy network. The terminal 1B is a terminal corresponding to the MVNO network. The terminal 1B is, for example, a MVNO subscriber terminal (a terminal with a contract with the MVNO). Note that a configuration example of the terminal 1A and the terminal 1B illustrated in FIG. 8 is the same as the configuration example of the terminal 1 of the first embodiment, and thus a detailed description is omitted.

  The terminal 1B may be, for example, an MTC device. The MTC device is, for example, a smart device (smart meter, smart TV, wearable terminal for monitoring power consumption at home), an industrial device, a car, a healthcare device, a home appliance, a medical device, a biological implant, and the like. MTC means a form of data communication that does not necessarily require human intervention, such as a smart meter. In other words, the MTC device can perform autonomous communication with a communication partner device. MTC is being standardized in a technical standard specification (such as 3GPP TS22.368). It is assumed that the MTC device performs communication at a specific time (for example, “every day, PM 12:00” or “every Friday, AM 3:00”). In this case, it is assumed that many similar MTC devices (eg, smart meters) start communicating at the same time, and a large amount of traffic occurs at a specific time. Such a large amount of traffic places a heavy load on the legacy network. Therefore, by processing such a large amount of traffic in, for example, the MVNO network, the load on the legacy network can be reduced.

  In the communication system illustrated in FIG. 7, the base station 2 is managed by an MNO that manages a legacy network. As illustrated in FIG. 7, the base station 2 can connect the terminal 1A to a legacy network. Further, the base station 2 can connect the terminal 1B to the MVNO network. Note that the configuration example of the base station 2 illustrated in FIG. 7 is the same as the configuration example of the base station 2 of the first embodiment, and thus detailed description is omitted.

  In the second communication system, the terminal 1B, which is a subscriber terminal of the MVNO, may perform wireless communication with the base station 2 using the unlicensed band frequency band.

  As illustrated in FIG. 7, the legacy network includes a plurality of network nodes (for example, SGW3A, PGW4A, MME5A). The functions of the network nodes (SGW3, PGW4, MME5) illustrated in FIG. 7 are the same as the functions described in the first embodiment, and a detailed description will be omitted.

  As illustrated in FIG. 7, in the MVNO network, at least a part of the functions of the network node is virtually operated by software. The function of the network node is operated by an application on a virtual machine, for example. The virtual network is built in, for example, a data center including servers and communication devices (routers and the like). In the virtual network, the function of the network node (for example, the function of the MME) may be operated by software such as a virtual machine.

  The MVNO network is constructed by, for example, dynamically scaling out and scaling in virtual machines. For example, the operator of the MVNO network can construct the MVNO network by dynamically activating the virtual machines according to the state of the communication traffic in the MVNO network. Further, the operator of the MVNO network can construct the MVNO network by, for example, dynamically starting a virtual machine in a predetermined time zone. The operator of the MVNO network can activate a virtual machine corresponding to a predetermined communication traffic or the communication traffic of the terminal 1B to dynamically construct the MVNO network. The operator of the MVNO network can start a virtual machine so as to satisfy a requirement for processing communication traffic (for example, Service Level Agreement (SLA)) and dynamically construct the MVNO network.

  The operator of the MVNO network can, for example, stop the virtual machines during a predetermined time period during which communication traffic is low, thereby suppressing resources allocated to the MVNO network and suppressing power consumption of the data center.

  In the second embodiment, for example, the MVNO network includes a virtual network node operated by a virtual machine dynamically constructed according to a request condition regarding processing of communication data of the terminal 1B. The required conditions are, for example, performance / communication band required for processing communication data of terminal 1B, SLA required for communication of terminal 1B which is an MTC device, time period during which communication by terminal 1B occurs, and the like. .

  FIG. 8 illustrates a configuration example of a communication device 100 according to the second embodiment. The communication device 100 is, for example, a server, a switch, a router, or the like. The communication device 100 operates a virtual machine that provides a function of a virtual network node (for example, a virtual SGW 3A, a virtual PGW 4A, a virtual MME 5A, or the like) in a virtual network.

  The communication device 100 includes a control unit 110 and a virtual network function (VNF) 120.

  The control unit 110 can operate the VNF 120 that provides the function of the virtual network node on the virtual machine. The control unit 110 may be configured by control software that can execute virtualization of a computer, such as a hypervisor.

  The control unit 110 can execute at least one of starting, stopping, and migrating a virtual machine that operates the VNF 120 (migrating a virtual machine to another communication device 100).

  Each of the virtual network nodes has, for example, the following functions.

Virtual P-GW4A:
-Packet processing function (User-Plane function)
A function for managing a charging state according to communication (PCEF: Policy and Charging Enforcement Function)
-Function to control policies such as QoS (PCRF: Policy and Charging Rule Function)

Virtual S-GW3A:
-Packet processing function (User-Plane function)
-Function for processing control signaling (C-Plane function)
・ Lawful Interception (LI) function for intercepting communication

Virtual MME5A:
-Function for processing control signaling (C-Plane function)
-Function to manage subscriber information of the communication system in cooperation with HSS (Home Subscriber Server)

  The VNF 120 operates on the virtual machine as the above-described virtual network node. In the embodiment described above, the VNF 120 is constructed for each virtual network node, but the VNF 120 may be constructed for each function of each virtual network node. For example, the VNF 120 may operate as a U-Plane function of the virtual PGW 4A on a virtual machine.

  In the example of FIG. 7, the network nodes included in the legacy network may be virtually operated by software or the like. In this case, the legacy network and the MVNO network may be constructed in the same data center, for example. When the legacy network and the MVNO network are constructed in the same data center, the legacy network and the MVNO network are constructed separately from each other. For example, the legacy network and the MVNO network are configured to be distinguished from each other as different tenants in a data center where a multi-tenant can be configured.

  FIG. 9 shows an operation example of the second embodiment. FIG. 9 shows an operation example in which the technology of the present invention is applied to “Attach Procedure” described in Chapter 5.3.2 of the specification (TS23.401 v12.3.0) of the 3GPP (3rd Generation Partnership Project) specification. Show.

  The terminal 1A transmits “RRC Connection Setup Complete” to the base station 2 as a response to “RRC Connection Setup” from the base station 2 (S2-1).

  The base station 2 selects an MME to which the terminal 1A is connected in response to receiving the “RRC Connection Setup Complete” (S2-2). The identification unit 20 of the base station 2 may identify the network corresponding to the terminal 1A, for example, based on information included in “RRC Connection Setup Complete”.

  The identification unit 20 identifies a network corresponding to the terminal 1A based on, for example, a PLMN included in “RRC Connection Setup Complete”, and selects an MME included in the network identified for the terminal 1A. The PLMN included in the “RRC Connection Setup Complete” transmitted from the terminal 1A indicates the network number of the legacy network or the MNO managing the legacy network. Therefore, in S2-2, the identification unit 20 identifies, for example, the terminal 1A as a terminal that has contracted with the MNO that manages the legacy network, and selects the MME 5 included in the legacy network for the terminal 1A. .

  The terminal 1A transmits to the base station 2 a message (“Attach Request”) requesting a connection to the network. The network switching unit 21 of the base station 2 transmits the “Attach Request” transmitted from the terminal 1A to the MME 5 of the legacy network corresponding to the terminal 1A (S2-3).

  In response to receiving the “Attach Request”, the MME 5 of the legacy network starts an EPS bearer establishment procedure (S2-4). With the start of the EPS bearer establishment procedure by the MME 5, control signals are exchanged between the SGW 3, the PGW 4, the MME 5, and the base station 2. An EPS bearer is established by exchanging control signals between the nodes. Terminal 1A communicates via the established EPS bearer. The network switching unit 21 of the base station 2 transmits and receives communication data regarding the terminal 1A via the EPS bearer.

  The terminal 1B transmits “RRC Connection Setup Complete” to the base station 2 (S2-5).

  The base station 2 selects an MME to which the terminal 1B is connected, in response to receiving the “RRC Connection Setup Complete” (S2-6). The identification unit 20 of the base station 2 may identify a network corresponding to the terminal 1B, and in this case, may identify the MVNO network as a network corresponding to the terminal 1B.

  The PLMN included in the “RRC Connection Setup Complete” transmitted from the terminal 1B indicates the MVNO network or the network identification number of the MVNO that manages the MVNO network. Therefore, in S2-5, the identification unit 20 identifies, for example, the terminal 1B as a terminal subscribed to the MVNO, and selects the virtual MME 5A included in the MVNO network for the terminal 1B.

  The terminal 1 </ b> B transmits a message (“Attach Request”) requesting connection to the network to the base station 2. The network switching unit 21 of the base station 2 transmits the “Attach Request” transmitted from the terminal 1B to the virtual MME 5A of the selected MVNO network (S2-7).

  In response to receiving the “Attach Request”, the virtual MME 5A starts an EPS bearer establishment procedure (S2-8). With the start of the EPS bearer establishment procedure by the virtual MME 5A, control signals are exchanged between the virtual SGW 3A, the virtual PGW 4A, the virtual MME 5A and the base station 2. An EPS bearer is established by exchanging control signals between the nodes. Terminal 1B communicates via the established EPS bearer. The network switching unit 21 of the base station 2 transmits and receives communication data regarding the terminal 1B via the EPS bearer.

  10 to 12 show other operation examples of the second embodiment. FIGS. 10 to 12 show an operation example when the MME 5 identifies the attribute / type of the terminal 1. FIG. 10 to 12 show operation examples in which the technology of the present invention is applied to “Attach Procedure” described in Chapter 5.3.2 of the 3GPP specification (TS23.401 v12.3.0).

  FIG. 10 shows an operation example of the terminal 1A corresponding to the legacy network.

  The terminal 1A transmits “Attach Request” to the base station 2 (S3-1). The base station 2 transmits “Attach request” to the MME 5 of the legacy network.

  The MME 5 executes a terminal authentication procedure in response to receiving the “Attach Request” (S3-2).

  The MME 5 identifies the attribute / type of the terminal in the authentication procedure (S3-3). The MME 5 identifies the attribute / type of the terminal based on the IMSI (International Mobile Subscriber Identity) included in the “Attach Request”. IMSI is terminal identification information.

  FIG. 12 shows an operation example in which the MME 5 identifies the terminal attribute / type in the authentication procedure. In the example of FIG. 12, the HSS 6 executes the authentication procedure in response to “Authentication Information Request” from the MME 5. Note that the MME 5 may execute the authentication procedure with reference to the HSS 6.

  The MME 5 transmits an “Authentication Information Request” to the HSS 6 (S3-10). "Authentication Information Request" includes the IMSI.

  The HSS 6 manages subscriber information of the communication system. The HSS 6 stores, for example, information on network subscribers and performs authentication of the user of the terminal 1. The HSS 6 provides, for example, the location information and the IP information of the terminal 1 to another device (for example, the MME 5).

  The HSS 6 authenticates the user of the terminal 1 based on the IMSI included in the “Authentication Information Request” received from the MME 5 and the stored information on the network subscriber (S3-11).

  The HSS 6 authenticates the user of the terminal 1 in response to receiving the “Authentication Information Request”. The HSS 6 searches for, for example, an IMSI included in “Authentication Information Request”, and authenticates the user of the terminal 1A according to the search result. The control unit 61 of the HSS 6 searches, for example, whether the IMSI included in “Authentication Information Request” is stored in the subscriber information database 60. The control unit 61 may search for the MNO with which the user of the terminal 1A has a contract with reference to the subscriber information database based on, for example, the IMSI included in “Authentication Information Request”. The control unit 61 executes authentication of the user of the terminal 1 according to the search result, for example.

  The HSS 6 includes the search result regarding the MNO with which the user of the terminal 1A has contracted in the “Authentication Information Answer” and transmits the search result to the MME 5 (S3-12).

  The MME 5 identifies that the terminal 1A corresponds to the legacy network based on “Authentication Information Answer” received from the HSS 6.

  The MME 5 identifies that the terminal 1A is compatible with the legacy network by the above-described identification procedure, and starts an EPS bearer establishment procedure (S3-4). The procedure for establishing the EPS bearer is the same as the operation example in FIG. 9, and thus detailed description is omitted.

  FIG. 11 shows an operation example of the terminal 1B corresponding to the MVNO network.

  The terminal 1B transmits “Attach Request” to the base station 2 (S3-5). The base station 2 transmits “Attach request” to the MME 5 of the legacy network.

  The MME 5 executes a terminal authentication procedure in response to receiving the “Attach Request” (S3-6). In the authentication procedure, the MME 5 identifies the attribute / type of the terminal based on the IMSI included in the “Attach Request” (S3-7). Note that the authentication procedure for the MME 5 to identify the terminal attribute / type is the same as the authentication procedure shown in FIG. 9, and thus detailed description is omitted.

  The MME 5 identifies that the terminal 1B corresponds to the MVNO network by the above-described identification procedure, and causes the base station 2 to reselect the MME (S3-8, "MME Selection Indication").

  For example, the MME 5 includes information on the MME to be reselected by the base station 2 in “MME Selection Indication” and transmits the MME 5 to the base station 2. The MME 5 includes, for example, the IP address of the MME (virtual MME 5A) of the MVNO network in the “MME Selection Indication”.

  The base station 2 transmits an “Attach Request” to the reselected MME in response to the reception of the “MME Selection Indication” (S3-9). For example, the base station 2 reselects the virtual MME 5A. The base station 2 transmits “Attach Request” to the reselected virtual MME 5A.

  In response to the reception of the “Attach Request”, the virtual MME 5A starts the procedure for establishing the EPS bearer in the MVNO network (S3-10). The procedure for establishing the EPS bearer is the same as the operation example in FIG. 10, and thus detailed description is omitted. The terminal 1B communicates with the Internet or the like via an EPS bearer constructed in a virtual network.

  FIG. 13 illustrates a configuration example of the MME 5 according to the second embodiment. The MME 5 has a function of instructing the base station 2 to reselect the MME in accordance with the network (or communication carrier) corresponding to the terminal and the attributes and types of the terminal.

  The MME 5 includes a virtual entity management unit 50 and a control unit 51.

  The virtual entity management unit 50 manages, for example, an address (IP address or the like) of the virtual MME 5A arranged in the MVNO network.

  The control unit 51 acquires the address of the virtual MME 5 </ b> A from the MVNO entity management unit 50 when the terminal that has transmitted “Attach Request” to the MV 5 is a terminal corresponding to the MVNO network. The control unit 51 transmits the obtained IP address to the base station 2 and instructs reselection of the MME. The base station 2 retransmits “Attach Request” to the virtual MME 5A of the IP address notified from the control unit 51.

  FIG. 14 is another configuration example of the communication system according to the second embodiment. The communication system illustrated in FIG. 14 includes, for example, a terminal 1, a base station 2, a legacy network, and an MVNO network.

  The legacy network includes, for example, the access network, the HSS 6, and the communication device 7 (for example, the S-CSCF 70, the P-CSCF 71, and the I-CFCF 72). The access network includes MME5. The MME 5 processes control signaling in cooperation with the HSS 6 that manages subscriber information of the communication system. The communication device 7 is a CSCF that provides a session control function in the IMS network. The MME 5, the HSS 6, and the communication device 7 have the same configurations as those of the MME 5, the HSS 6, and the communication device 7 illustrated in FIG. 5, and thus a detailed description is omitted.

  The MVNO network includes, for example, an access network, an HSS 6A, and a communication device 7A (for example, an S-CSCF 70A, a P-CSCF 71A, and an I-CFCF 72A). The access network includes the MME 5A. Since the MME 5A, the HSS 6A, and the communication device 7A have the same configurations as the MME 5, the HSS 6, and the communication device 7 included in the legacy network, detailed description will be omitted.

  In the example of the second embodiment described above, the network nodes included in the MVNO network are virtually operated by software or the like. Therefore, the MNO that manages the MVNO network can easily and at low cost construct a network node that provides a backbone network function such as EPC by software.

<Third embodiment>

  As illustrated in FIG. 15, the communication system according to the third embodiment includes an RRH (Remote Radio Head: wireless unit) 22 and a BBU (Base Band Unit: baseband processing unit) 23. In the communication system illustrated in FIG. 15, the RRH 22 is managed by the MNO managing the legacy network, and the BBU 23 is managed by the MVNO. The RRH 22 may be managed by the MVNO instead of the MNO managing the legacy network. Note that the BBU 23 may be connected to a plurality of RRHs 22. The RRH 22 performs analog Radio Frequency (RF) signal processing. The BBU performs analog Radio Frequency (RF) signal processing.

  The RRH 22 is responsible for analog RF signal processing and provides an air interface to mobile stations. The analog RF signal processing includes D / A conversion, A / D conversion, frequency up-conversion, frequency down-conversion, amplification, and the like.

  FIG. 16 shows a configuration example of the RRH 22 of the third embodiment. As illustrated in FIG. 17, the RRH 22 includes a management unit 220 and a communication unit 221.

  The management unit 220 manages information on the BBU 23 managed by the MVNO. The management unit 220 manages, for example, identification information on the BBU 23 (for example, the address of the BBU 23). Further, the management unit 220 may, for example, associate a flag indicating whether the BBU 23 is a network node included in the MVNO network with the identification information of the BBU 23.

  The communication unit 221 refers to the management unit 220 and communicates with the BBU 23 operated by the MVNO. The communication unit 221 transfers the communication traffic from the terminal 1B to the BBU 23 with reference to the management unit 220. The communication unit 221 refers to the management unit 220, for example, and transfers communication traffic from the terminal 1B to the BBU 23 based on predetermined information included in a connection request from the terminal 1B. The communication unit 221 transfers the communication traffic from the terminal 1B to the BBU 23 based on the PLMN included in the connection request from the terminal 1B with reference to the management unit 220, for example.

  The BBU 23 is connected to a higher-level network (eg, a backhaul network or a core network of the MNO), and controls and monitors a wireless base station and performs digital baseband signal processing. Digital baseband signal processing includes layer 2 signal processing and layer 1 (physical layer) signal processing. Layer 2 signal processing includes (i) data compression / decompression, (ii) data encryption, (iii) addition / deletion of layer 2 header, (iv) data segmentation / concatenation, and (v) data multiplexing. / Generation / decomposition of transfer format by separation. In the case of E-UTRA as one of the specific examples, the layer 2 signal processing includes processing of Radio Link Control (RLC) and Media Access Control (MAC). Physical layer signal processing includes channel coding / decoding (Channel Coding / Decoding), modulation / demodulation (Modulation / Demodulation), spreading / de-spreading (Spreading / De-spreading), resource mapping, and Inverse Fast Fourier Transform (Transformation / Decoding). This includes generation of OFDM symbol data (baseband OFDM signal) by IFFT).

  The functions executed by the BBU 23 can be executed by software such as a virtual machine. The function provided by the BBU 23 can be operated on a virtual machine as the VNF 120, for example. The BBU 23 can be operated by the MVNO in the data center, for example.

  FIG. 17 shows a configuration example of the BBU 23 according to the third embodiment. As illustrated in FIG. 17, the BBU 23 includes a management unit 230 and a control unit 231.

  The management unit 231 manages information about a virtual network (MVNO network) operated by the MVNO. The management unit 231 manages information on network nodes included in the MVNO network, for example. The management unit 231 manages, for example, identification information (for example, the address of the virtual MME 5A) related to the network node included in the MVNO network.

  The control unit 231 refers to the management unit 223 and transmits a NAS (Non Access Stratum) message to the virtual MME 5A operated by the MVNO subscribed to the terminal 1B.

  In the communication system according to the third embodiment, the MVNO may manage the RRH 22. In this case, the MNO managing the legacy network may lend a licensed band to the MVNO, for example. The RRH 22 managed by the MVNO communicates with the terminal 1B using, for example, the licensed band lent by the MNO managing the legacy network.

  The RRH 22 may be installed at a plurality of points by, for example, the MVNO. The MVNO may install the RRHs 22 at, for example, a large number of points in accordance with the communication service to be provided and the use status, the use area, the use range, and the like of the service attached to the communication service. The MVNO may provide the RRH 22 at a low price (extremely free), for example, to a subscriber subscribed to the MVNO.

  In the communication system according to the third embodiment, the RRH 22 managed by the MVNO may communicate with the terminal 1B using an unlicensed band frequency band.

  The operation example of the third embodiment is similar to the operation example of the first embodiment shown in FIG. 4 or the operation example of the second embodiment shown in FIGS. Omitted. The functions of the base station 2 in FIG. 4 or FIGS. 9 to 12 are executed by the RRH 22 and the BBU 23.

  In the communication system according to the fourth embodiment, the MVNO network includes an application that provides a predetermined service using communication data of a subscriber terminal of the MVNO. Since the MVNO includes an application for providing a predetermined service in the MVNO network, the MVNO can provide the predetermined service using the communication data of the subscriber terminal of the MVNO collected without passing through the legacy network. Therefore, the MVNO can provide a predetermined service using the communication data without passing the communication data of the subscriber terminal of the MVNO to the MNO. That is, the fourth embodiment is an embodiment in the case where a cloud provider that provides various services owns (manages) the MVNO network.

  The MVNO may provide a predetermined service using, for example, communication data transmitted by a plurality of subscriber terminals of the MVNO. The MVNO can provide a predetermined service using a large amount of communication data collected from a plurality of subscriber terminals, for example. The MVNO may, for example, reduce the communication fee (use fee) of the MVNO subscriber terminal, instead of earning income from a service provided using communication data collected from the subscriber terminal. The MVNO, for example, can lower the communication fee of the subscriber terminal of the MVNO compared to the MNO, and can be a differentiating factor from the MNO.

  FIG. 18 illustrates a configuration example of a communication system according to the fourth embodiment.

  In FIG. 18, a terminal 1B is a device capable of collecting predetermined data. The terminal 1B is a device capable of collecting moving image data, such as a monitoring camera.

  Hereinafter, an example of the fourth embodiment will be described with reference to the drawings.

<Example 1>
FIG. 19 is a configuration example of a communication system according to Example 1 of the fourth embodiment.

  In the communication system illustrated in FIG. 19, the terminal 1B is a device capable of collecting moving image data, such as a monitoring camera. The terminal 1B collects the moving image data and transmits the collected moving image data to the base station 2 as communication data. The terminal 1B, which is a monitoring camera or the like, captures, for example, a predetermined monitoring area and transmits the captured moving image data to the base station 2 as communication data. The communication system illustrated in FIG. 19 may include a plurality of monitoring cameras and the like (terminal 1B). The plurality of surveillance cameras and the like (terminal 1B) each collect moving image data at different points and transmit the collected moving image data to the base station 2 as communication data.

  In Example 1 of the fourth embodiment, the terminal 1B, which is a surveillance camera or the like, is, for example, a company, a local government, a police, or an individual who is provided with a service from a cloud operator having an MVNO network. A company, a local government, a police, an individual, or the like who receives a service provided by the cloud service provider may receive a fee from the MVNO instead of having the MVNO use the terminal 1B that is a monitoring camera or the like owned by the company. Also, MVNO, which is a cloud operator, can reduce the communication fee of the subscriber terminal if the company, the local government, the police, the individual, etc. that provides the service owns the MVNO subscriber terminal separately from the terminal 1B. (Or for free). The terminal 1B, which is a monitoring camera or the like, may be held by, for example, MVNO, or may be distributed to companies, municipalities, police, and individuals at low cost (or free of charge) by MVNO.

  As illustrated in FIG. 19, in the communication system according to the first embodiment, the MVNO network includes an image analysis application 8A and a map application 8B.

  The image analysis application 8A includes, for example, a function of analyzing moving image data of a monitoring camera or the like. The image analysis application 8A specifies, for example, whether moving image data captured by a surveillance camera or the like includes an object to be monitored (a person, an animal, a car, or the like). The image analysis application 8A includes, for example, an abnormal object (for example, a person hiding a part of the face, an object not normally detected (suspicious object), or the like) in the moving image data captured by the monitoring camera or the like. Specify whether or not. For example, the image analysis application 8A reads, from moving image data captured by a surveillance camera or the like, an object that moves abnormally (for example, an object that moves at a predetermined speed or more, an object that suddenly stops (stops), )).

  The image analysis application 8A may detect, for example, an unusual state (for example, occurrence of fire or smoke, increase in river water, or occurrence of traffic congestion) from a moving image captured by a monitoring camera or the like.

  The image analysis application 8A may analyze, for example, moving image data captured by a plurality of monitoring cameras or the like. For example, the image analysis application 8A may track the movement of an object (a person, an animal, a car, or the like) to be monitored from moving image data captured by a plurality of monitoring cameras that monitor different points. The image analysis application 8A detects, for example, a range in which an unusual state occurs (for example, a range in which traffic congestion occurs) from moving image data captured by a plurality of surveillance cameras installed at different points. May be.

  Note that the content analyzed by the image analysis application 8A from the moving image data captured by the surveillance camera or the like is not limited to these examples, but may be any content that can be analyzed using the moving image data. Is also good.

  The map application 8B includes, for example, a function of creating map data in which an analysis result of the image analysis application 8A is displayed on a map. For example, based on the position of the terminal 1B (surveillance camera or the like) and the analysis result of the image analysis application 8A, the map application 8B detects a point where an object to be monitored, an abnormal object, or an object performing abnormal movement is detected. Create map data that displays on a map. The map application 8B may create, for example, map data in which a point where an unusual state has occurred is displayed on a map. The map application 8B, for example, based on the positions of the plurality of terminals 1B (surveillance cameras and the like) and the analysis result of the image analysis application 8A, moves (tracks) the monitoring target object or a state different from the normal state (tracking state). For example, map data in which a range in which a disaster occurs) may be displayed on a map.

  In the map data created by the map application 8B, the method and content of displaying the analysis result of the image analysis application 8A on the map are not limited to these examples, and any method and content may be used.

  As illustrated in FIG. 19, in the communication system according to the first embodiment, map data created by the map application 8B is transmitted to the terminal 1A. The map data created by the map application 8B is transmitted, for example, to the terminal 1A, which is a subscriber terminal of the MNO, via a legacy network. When the terminal 1A is an MVNO subscriber terminal, the map data created by the map application 8B is notified to the terminal 1A via the MVNO network. The terminal 1A displays the map data notified via the MVNO network on a screen or the like.

Further, the EMS application 8C instructs a power storage device, an EV charging device, or the like to start charging based on, for example, an actual measurement value or a prediction value regarding power demand or supply. The EMS application 8C, for example, instructs the start of power storage or charging in a time zone where power consumption is low, and instructs the stop of power storage or charging or the start of discharge (such as sales of power) in a time zone where power consumption is high. Thus, it is possible to optimize the power consumption as a whole in the smart house.

  The EMS application 8C may, for example, issue an instruction regarding power to the plurality of terminals 1C based on information regarding power collected from the plurality of terminals 1B. In this case, for example, the EMS application 8C can optimize power consumption in a plurality of buildings including the terminal 1C. The EMS application 8C manages and controls the power consumption in the entire city (smart city), for example, supplying power from a surplus area to an area where power is insufficient in the city. Thus, power consumption can be optimized over a wide range.
