Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention within the scope of the claims. Also, not all combinations of features described in the embodiments are essential to the means of solving the invention.

FIG. 1 schematically shows an example of the system 10. The system 10 includes a network 100 and a network 200. The network 200 is connected to the network 100. One network 200 may be connected to the network 100. A plurality of networks 200 may be connected to the network 100.

The network 100 and the network 200 can provide a so-called 5G-compliant wireless communication service to the UE (User equipment) 300. The network 100 may be an example of the first network. The network 200 may be an example of the second network. The UE 300 may be an example of a communication terminal.

The network 100 has a control plane function and a user plane function. The network 100 is, for example, a mobile carrier network possessed by a mobile carrier. The network 100 may be 5GC. Network 100 may provide public 5G. Public 5G may be a service in which a telecommunications carrier constructs and operates a network in order to provide a uniform NW service nationwide to all customers contracted by the telecommunications carrier.

The network 200 does not have a control plane function but has a user plane function. The network 200 may provide so-called local 5G. Local 5G may refer to a service in which a customer himself / herself (or a contractor from a customer) constructs and operates a network in order for the customer himself / herself to use a dedicated network service for his / her specific area. The network 200 may be a local 5G network. The network 200 may provide so-called private 5G. Private 5G may refer to a service in which a telecommunications carrier constructs and operates a network in order to provide a dedicated network service to a specific customer in a specific area (business establishment of a specific customer, etc.). The network 200 may be a private 5G network.

In the system 10 according to the present embodiment, the control plane function of the network 100 executes the communication control in the network 100 and the communication control in the network 200. That is, the control plane function of the network 100 also operates as the control plane function of the network 200.

Conventionally, a network in a mobile phone system has been constructed for each carrier, and roaming is generally used when communicating across carriers. In order to realize roaming, it is necessary to have experience and operation technology to enable sufficiently mature equipment and operation in each carrier, and it is necessary to have a certain cost to realize and maintain the service. Therefore, it is not possible to easily create a new business.

Meanwhile, a market such as local 5G, where users build and operate themselves rather than carriers, is being created. Currently, it is assumed that users will independently build and operate 5GC, and it is expected that they will struggle because they fall under the above problems. That is, even if it is a local 5G, the required 5GC is equivalent to the NF (Network Function) possessed by the mobile phone carrier, so that there is the first problem that it takes time and effort to construct and maintain the operation.

Also, when considering services such as local 5G from the user's point of view, if a general communication terminal such as a smartphone is assumed, the network can be seamlessly switched between the mobile carrier network and the constructed local 5G area. Need to be done. For example, when a university wants to provide services such as accessing an intranet system for students on a university campus, and when a device for accessing the system is enabled by a student's smartphone, a mobile carrier network and If you try to switch to the local 5G area in the university by roaming, the communication will be cut off once. This is because each of the mobile carrier network and the local 5G area will use the AMF (Access and Mobility Management Function) constructed by each person, and this switching will be performed. It is not desirable that the communication connection is temporarily disconnected when moving from outside the university to inside the university, which leads to a decrease in QoE (Quality of Experience). That is, although it is not essential, when targeting a device such as a smartphone, there is a second problem that it is desirable to smoothly move between the carrier network and the local network.

On the other hand, in the system 10 according to the present embodiment, by adopting a configuration in which the 5GC control plane functions of the network 100 and the network 200 are collectively performed in the network 100, it contributes to the solution of the first problem. Can be done. Further, in the system 10 according to the present embodiment, the movement of the UE 300 between the area 104 generated by the gNB (gNodeB) 102 of the network 100 and the area 204 generated by the gNB 202 of the network 200 is performed by the network 100. The side automatically detects it and executes the process for smooth switching. This can contribute to the solution of the second problem. gNB may be an example of a radio base station.

2 and 3 schematically show an example of network 100 and network 200. The network 100 includes gNB102, UPF (User Plane Function) 106, AMF110, SMF (Session Management Function) 112, AUSF (Authentication Server Function) 114, UDM (Unified DataDataUni) It is equipped with a Network Authentication Function 120, a PCF 122 (Police Control Session), a NEF (Network Exposure Session) 124, and an AF (Application Function) 130.

It can be said that UPF106, AMF110, SMF112, AUSF114, and UDM116 are network functions that must be provided at the minimum necessary in order to provide a communication service compliant with 5G. In order to provide high-performance services in 5G, network functions other than these must be added. Further, in order to provide a voice service, an IMS (IP Multimedia Subsystem) core must be further provided. It is very costly and time-consuming to prepare such equipment on the user side, so the key is how to reduce the number of network functions and operate it.

In the system 10 according to the present embodiment, the network 200 includes gNB202, UPF206, and MEC (Mobile Edge Computing) 208, and does not have a control plane function. The network 200 does not have to include the MEC 208.

As shown in FIG. 2, when the UE 300 is connected to the gNB 102, the control plane is controlled by the control plane function group including the AMF 110. The user plane is controlled by the UPF 106, and voice and data exchange is realized via the DN (Data Network) 20.

As shown in FIG. 3, when the UE 300 moves and is connected to the gNB 202, the control plane is controlled by the control plane equipment group including the AMF 110 of the network 100. The user plane is controlled by UPF206. The UPF 206 can select a route by identifying the communication partner by, for example, the IP address of the communication partner of the UE 300.

For example, the UPF 206 exchanges data for the outside and data from the outside via the DN 20. In this way, the network load on the carrier side can be reduced by taking a configuration in which the UPF 206 on the local side is connected to the Internet or the like via the DN20. Therefore, for example, when passing through the UPF 206 on the local side, the packet charge is charged. It is possible to realize services such as making the service free of charge.

The UPF 206 may be routed via the UPF 106 for voice. The UPF 106 accesses the IMS core included in the carrier of the network 100 via the DN 20 in the same manner as when handling the voice of the UE 300 connected to the gNB 102. In order to realize the voice service, an IMS core is required and a large-scale equipment is required. However, by passing the UPF 206 via the UPF 106, it is possible to eliminate the need to prepare the IMS core or the like on the network 200 side. ..

UPF206 directly exchanges data for MEC208 and data from MEC208 with MEC208. As a result, it is possible to provide the UE 300 connected to the gNB 202 with a low-latency service using the MEC 208 on the network 200 side.

As described above, in order to realize the switching of the network, it is necessary to detect the movement of the UE 300 between the area 104 by the network 100 and the area 204 by the network 200. In the system 10 according to this embodiment, the AF 130 may perform such detection. AF130 may be an example of a server.

FIG. 4 schematically shows an example of the functional configuration of the AF 130. The AF 130 includes a data storage unit 132, an internal communication unit 134, an external communication unit 136, and a detection unit 138.

The data storage unit 132 stores various data. The data storage unit 132 stores, for example, associated data in which the area identification information of the area 204 generated by the gNB 202 in the network 200 and the terminal identification information of the UE 300 permitted to use the area 204 are associated with each other. .. The data storage unit 132 may store associating data for each of the plurality of areas 204 with the area identification information and the terminal identification information of one or a plurality of UEs 300 permitted to use the area 204. ..

The area identification information may be any information as long as the area 204 can be identified. For example, the area identification information is TAC (Tracking Area Code). Further, for example, the area identification information is gNB ID. Further, for example, the area identification information is a cell ID.

The terminal identification information may be any information as long as it can identify the UE 300. For example, the terminal identification information is SUPI (Subscription Permanent Identifier). Further, for example, the terminal identification information is MSISDN (Mobile Subscriber Integrated Services Digital Network Number).

The data storage unit 132 may store the network setting information applied to the UE 300 when the UE 300 authorized to use the area 204 is located in the area 204. As typified by the concept of network slicing, 5GC is equipped with a function that can change the profile and configuration of the network according to the purpose. It is possible to change the operation for each user / application. For example, when you want to communicate locally like MEC, you can switch the UPF to be used to a place closer to the edge side or use the RAN side (gNB). It is possible to switch the frame format to be used. The network setting information may include information about such network functions applied to the UE 300. The network setting information includes, for example, UPF selection information. The network setting information includes, for example, network slicing information. The network setting information may include any setting information other than these, which is applied to the UE 300.

The internal communication unit 134 communicates with the inside of the network 100. The internal communication unit 134 may communicate with the internal network function of the network 100 via the NEF 124. The NEF 124 may be an example of a relay unit that is arranged in the network 100 and relays communication between the AF 130 and the network function in the network 100.

Regarding NEF124, the role defined in 3GPP (Third Generation Partnership Project) is to securely disclose the network functions and events provided by 3GPP NF to AF130, and AF safely distributes information to the 3GPP network. To provide the means to provide, to assist AF authentication / approval / throttling, to convert the information received from AF into information to be transmitted to 3GPP NF, and to transmit the information received from 3GPP NF to AF. It is to support the conversion into information and the disclosure of information collected from 3GPP NFs other than NEF to AF. In this way, NEF124 exists in the form of a boundary of 3GPP NW, and is an agent for disclosing policy changes (QoS, etc.) and collected information to an external AP (AF130).

The external communication unit 136 communicates with the outside of the network 100. The external communication unit 136 executes communication via the Internet, for example. The external communication unit 136 communicates with, for example, the administrator of the network 200. For example, when the network 200 is used to provide a wireless communication service in a university, the external communication unit 136 communicates with a communication device used by an administrator or the like of the network 200 via the Internet. The communication device may be, for example, a PC (Personal Computer), a tablet terminal, a smartphone, or the like.

The external communication unit 136 may receive the associated data and store it in the data storage unit 132. The external communication unit 136 may accept editing of the associated data stored in the data storage unit 132.

The external communication unit 136 may receive the network setting information and store it in the data storage unit 132. The external communication unit 136 may accept editing of the network setting information stored in the data storage unit 132.

The detection unit 138 detects that the UE 300 authorized to use the area 204 is in the area 204 generated by the gNB 202 in the network 200. The detection unit 138 may detect that the UE 300 permitted to use the area 204 is in the area 204 by using the associated data stored in the data storage unit 132.

For example, the detection unit 138 transmits the associated data to the AMF 110 in the network 100, and notifies that the UE 300 authorized to use the area 204 is in the area 204 generated by the gNB 202 in the network 200. Is detected by receiving from the AMF110. For example, the AMF 110 acquires information on the UE 300 connected to the area 204, and includes a combination of the area identification information of the area 204 and the terminal identification information of the UE 300 in the correspondence data. Judge whether or not. Then, when it is determined that the AMF 110 is included, the AMF 110 transmits the notification information including the terminal identification information of the UE 300 and the area identification information of the area 204 to the AF 130.

The AMF110 may use a PRA ID (Pressure Reporting Area ID). The AMF 110 stores, for example, the associated data and the PRA ID in association with each other. Then, the AMF 110 performs a conditional search with the area information in association with the UE 300 connected to the area 204 and the PRA ID set in advance. When the connected UE 300 meets the conditions, the AMF 110 transmits to the AF 130 notification information notifying the AF 130 that the UE 300 permitted to use the area 204 is located in the area 204.

Communication from AF130 to AMF110 may be via NEF124 and SMF112. A rule may be created between SMF112 and AMF110 by, for example, PRA ID.

The notification method from AMF110 to AF130 may be any method as long as it complies with 3GPP. The AMF 110 notifies the AF 130 via, for example, the PCF 122 and the NEF 124. Further, the AMF 110 notifies the AF 130 via, for example, the NEF 124.

According to 3GPP 23.501, AMF 110 provides "UE mobility event notification service" to NEF124, PCF122, SMF112 and the like. This function can detect the location movement of the mobile device based on the contents notified from these NFs. The location referred to here is associated with the PRA ID, and Tracking Area / Cell identifers / NG-RAN node identifiers are set. For example, AMF110 detects that a mobile device has arrived at the set Tracking Area. It is possible to notify an NF such as SMF112.

Further, for example, the detection unit 138 gNB202 in the network 200 based on the terminal identification information of the UE 300 received from the UE 300, the area identification information of the area to which the UE 300 is connected or located, and the associated data. It is detected that the UE 300 authorized to use the area 204 is in the area 204 generated by the above.

In the UE 300, the latitude / longitude information and the cell identification information of the UE 300 can be acquired by hitting the API (Application Programming Interface) from the OS (Operating System) side to the modem side. The UE 300 pre-installs, for example, a dedicated application capable of transmitting information to the AF 130 via the Internet. The dedicated application periodically hits the API against the OS at an arbitrary frequency such as once every 30 minutes or once an hour, and displays the cell identification information to which the UE 300 is connected or is in the service area. get. Then, the dedicated application transmits the acquired cell identification information and the terminal identification information of the UE 300 to the AF 130.

The dedicated application may transmit the latitude / longitude information of the UE 300 and the terminal identification information of the UE 300 to the AF 130. In this case, the AF 130 may determine whether or not the UE 300 is located in the area 204 based on the latitude / longitude information of the UE 300.

The internal communication unit 134 relates to the UE 300 stored in the data storage unit 132 in response to the detection by the detection unit 138 that the UE 300 permitted to use the area 204 is located in the area 204. The network setting information is transmitted to the network function in the network 100 via the NEF124. The internal communication unit 134 transmits, for example, network setting information regarding the UE 300 to the AMF 110. Further, the internal communication unit 134 transmits, for example, network setting information regarding the UE 300 to the NSSF 120.

FIG. 5 schematically shows an example of the processing flow by the AF 130. Here, the correspondence data and the network setting information (may be described as NW setting information) received by the external communication unit 136 from the communication device such as the administrator of the network 200 are stored in the data storage unit 132. The processing flow when the state is set to the start state and the target is one UE 300 is schematically shown.

In the step (the step may be abbreviated as S) 102, the internal communication unit 134 transmits information to the AMF 110 via the NEF 124. The internal communication unit 134 may transmit the associated data to the AMF 110.

In S104, the detection unit 138 determines whether or not the area IN notification for notifying that the UE 300 permitted to use the area 204 is located in the area 204 has been received from the AMF 110. If it is determined that the signal has been received, the process proceeds to S106.

In S106, the internal communication unit 134 notifies the NEF 124 of the network setting terminal information (which may be described as NW setting terminal information) which is the information of the UE 300 and the NW setting information regarding the UE 300. The NW setting information may be information common to a plurality of UEs 300 that are permitted to use the area 204. Further, the NW setting information may be information set for each of a plurality of UEs 300 that are permitted to use the area 204. Upon receiving the NW setting information, the NEF 124 notifies the related network function of necessary information.

In S108, the detection unit 138 determines whether or not the area OUT notification for notifying that the UE 300 located in the area 204 has left the area 204 has been received from the AMF 110. If it is determined that the signal has been received, the process proceeds to S110.

In S110, the internal communication unit 134 notifies the NEF 124 of the NW setting terminal information of the UE 300 exiting from the area 204 and the NW setting cancellation information for canceling the NW setting related to the UE 300. Upon receiving the NW setting cancellation information, the NEF 124 notifies the related network function of necessary information in order to cancel the NW setting of the UE 300.

The AF 130 may execute the process shown in FIG. 5 for each of the plurality of UEs 300. The process shown in FIG. 5 may be continuously executed, for example, until a stop instruction is received from the administrator of the network 100 or the like.

FIG. 6 schematically shows an example of the processing flow by the AF 130. Here, the differences from FIG. 5 will be mainly described.

In S202, the external communication unit 136 receives the latitude / longitude information of the UE 300 from the UE 300. In S204, the detection unit 138 determines whether or not the UE 300 is located in the area 204 that the UE 300 is permitted to use. For example, the detection unit 138 stores range information indicating the positional range of the area 204 in advance, and determines that the UE 300 is located in the area 204 when the latitude / longitude of the UE 300 is included in the range of the area 204. .. If it is determined that it is not located in the area 204, it returns to S202, and if it is determined that it is located in the area 204, it proceeds to S206. In S206, the internal communication unit 134 notifies the NEF 124 of the NW setting terminal information which is the information of the UE 300 and the NW setting information regarding the UE 300.

In S208, the external communication unit 136 receives the latitude / longitude information of the UE 300 from the UE 300. In S210, the detection unit 138 determines whether or not the UE 300 located in the area 204 has exited the area 204. If it is determined that it has not come out, it returns to S208, and if it is determined that it has come out, it proceeds to S212.

In S212, the internal communication unit 134 notifies the NEF 124 of the NW setting terminal information of the UE 300 exiting from the area 204 and the NW setting cancellation information for canceling the NW setting related to the UE 300. Upon receiving the NW setting cancellation information, the NEF 124 notifies the related network function of necessary information in order to cancel the NW setting of the UE 300.
