[0011] Embodiment 1 The communication control device according to the embodiment will be described below with reference to the drawings. Fig. 1 is a block diagram showing an example of the configuration of a communication control device 100 and a communication system 1 thereof.

[0012] The communication control device 100 includes an authentication unit 101 and a control unit 102. The authentication unit 101 performs face authentication based on face image information of a user captured by a camera. The control unit 102 controls communication so as to prioritize communication with the user terminal 210 of the user based on schedule information indicating the schedule of the face-authenticated user. In this way, wireless communication can be appropriately controlled.

[0013] Embodiment 2 In this embodiment, for example, a communication control device controls communications in a wireless communication network in a school or the like. The communication control device controls communications of multiple user terminals (also referred to as UEs). Specifically, the communication control device prioritizes communications of one or more user terminals connected to the network. The users are students, and each user has a user terminal. The user terminal is a mobile communication terminal such as a smartphone, tablet PC, mobile phone, or laptop. The user terminal may also be a wearable terminal.

[0014] A local 5G (Fifth Generation) network has been constructed within a school. Multiple users within the school connect to a 5GC (fifth generation core) network using user terminals. This allows users to access the school network. Users can attend online lectures using their own user terminals. Furthermore, users can view content related to lectures, etc., using their own user terminals. To ensure smooth lectures, the communication control device controls communication so that priority is given only to users attending lectures.

[0015] The communication control device and the system thereof will be described with reference to Figures 2 and 3. Figure 2 is a block diagram showing an example of the configuration of a communication system 1 using a communication control device 100. Figure 3 is a schematic diagram for explaining an example of the communication system 1. In the communication system 1, for example, an in-campus network (also referred to as NW) 500 installed in a school is constructed. One or more lecture rooms 200 are installed on the campus.

[0016] One or more cameras 201 are installed in the lecture room 200. The camera 201 may be a security camera, a monitoring camera, or the like. The camera 201 may also be a device dedicated to face recognition. The camera 201 is installed on the ceiling or above a wall. The camera 201 captures images of users in the lecture room 200. User U1 is attending a lecture in the lecture room 200. User U2 is outside the lecture room. Therefore, the camera 201 cannot capture an image of user U2. Note that although only one camera 201 is shown in Figures 2 and 3, multiple cameras 201 may be installed in the lecture room 200. Multiple cameras 201 may also be installed in a facility such as a school building.

[0017] As shown in Fig. 2, users U1 and U3 are attending a lecture in a lecture room 200. A camera 201 captures images of users U1 and U3 attending the lecture. Within the lecture room 200, user U1 uses UE 211, and user U3 uses UE 213. Outside the lecture room 200, user U2 uses UE 212.

[0018] The communication control device 100 controls communication so that the UE 211 of user U1, who is attending a lecture, and the UE 213 of user U3 are in prioritized communication. On the other hand, user U2 is outside the lecture room 200 and is not attending the lecture. Therefore, the communication control device 100 controls communication so that the UE 212 of user U2 is in normal communication. The communication speed of prioritized communication is faster than the communication speed of normal communication. For example, in a 5G core network, the communication control device 100 preferentially transmits packets of the UE 211, which is in prioritized communication. The following explanation will focus on processing for the UE 211 of user U1. In other words, the processing for the UE 213 of user U3 is the same as that for the UE 211 of user U1, and therefore will not be explained as appropriate.

[0019] The camera 201 transmits facial information related to a facial image of the user U1 to the communication control device 100. The facial information is image data including the face of the user U1. The facial information may be moving image data or still image data captured periodically. The facial information may be a portion of an image cut out from a camera image so as to include the face. Alternatively, the facial information may be feature amount data extracted from the facial image. In other words, the camera 201 or the like may extract data for facial authentication by performing image processing. The camera 201 then transmits the extracted data as facial information to the communication control device 100. The communication between the communication control device 100 and the camera 201 may be wired communication or wireless communication.

[0020] The communication control device 100 includes an authentication control device 110, a QoS (Quality of service) control device 120, and a PCF (Plane control function) 130. The authentication control device 110 has the same functions as the authentication unit 101 in FIG. 1. Therefore, the authentication control device 110 performs face authentication based on facial photo data of user U1. The QoS control device 120 has the same functions as the control unit 102 in FIG. 1. Communication control is performed so that wireless communication of the UE 211 of user U1 is prioritized communication. An example of this control will be described in detail below.

[0021] Server 300 includes a student information server 310 and an academic affairs information server 320. Student information server 310 has a database and stores information about each student (user). Student information server 310 stores student ID number 311 and facial photo data 312. Student ID number 311 is a number assigned to each student user. In other words, student ID number 311 is a unique identifier assigned to each user. In other words, student ID number 311 corresponds to a user ID (identifier) ​​for identifying a student user.

[0022] The facial photo data 312 is image data of a facial photo of each user. The facial photo data 312 is acquired in advance for each user. For example, the server 300 can acquire the facial photo data 312 by capturing a facial photo of the user at the time of enrollment. Note that the facial photo data 312 is not limited to the image data itself, but may be data extracted from the image data for facial recognition. For example, it may be feature data extracted from the image data using a filter or the like. The student information server 310 stores the facial photo data 312 for each user. In other words, the student information server 310 registers the user's student ID number 311 and the facial photo data 312 in association with each other.

[0023] The academic affairs information server 320 has a database that stores information about the academic affairs of each student. The academic affairs information server 320 stores student information 321 and lecture QoS information 322. The student information 321 is information about each user's lecture schedule. The student information 321 includes information such as the time of the lecture, the name of the lecture, and the lecture room (lecture location) where the lecture is held. For each user, the lecture time, lecture name, and lecture location are associated. The student information 321 registers information about the user's location in the facility according to time. The student information 321 indicates the user's lecture schedule, and is therefore also referred to as schedule information. The student information 321 may store the user's student ID number 311 and the UE terminal ID in association with each other. This allows the communication control device 100 to identify the UE used by the user.

[0024] Lecture QoS information 322 is information indicating the QoS of a lecture. For example, in lecture QoS information 322, a QoS is specified for each lecture. The QoS specified in lecture QoS information 322 is also called specified QoS. For example, lecture QoS information 322 indicates whether or not prioritized communication is to be performed for each lecture. Lectures that use a network are registered as lectures with prioritized communication. Specifically, online lectures, lectures in which participants speak with other users in remote locations, two-way lectures, lectures in which participants take online content, etc. are registered as prioritized communication. Lectures that do not use a network are registered as normal communication.

[0025] Hereinafter, it is assumed that the lecture that user U1 is attending in lecture room 200 is registered as a lecture with prioritized communication. Note that lecture QoS information 322 is set for each lecture, but it may also be set by subdividing it according to time periods within the lecture. For example, the first half of the lecture time may be prioritized communication, and the second half may be normal communication. In this way, only the time period during which online content is attended can be set as prioritized communication.

[0026] The authentication control device 110 performs face authentication by referring to the student ID number 311 and face photo data 312. For example, when face information is received from the camera 201, the authentication control device 110 performs face authentication using the face photo data 312. The authentication control device 110 compares the face information with the face photo data 312 to determine whether the data match. A user who is successfully authenticated is also called an authenticated user. The authentication control device 110 obtains the student ID number 311 of the authenticated user and outputs it to the QoS control device 120.

[0027] The QoS control device 120 acquires student information 321 of the authenticated user indicated by the student ID number 311. The QoS control device 120 refers to the student information 321 to identify the current lecture of the authenticated user. The QoS control device 120 identifies the current lecture indicated in the lecture schedule of the authenticated user, and identifies the lecture location of the lecture and the lecture QoS information 322. The QoS control device 120 determines whether the lecture location indicated by the student information 321 matches the installation location of the camera 201.

[0028] When the lecture location indicated by the student information 321 matches the installation location of the camera 201, the QoS control device 120 changes the QoS policy in accordance with the lecture QoS information 322. That is, the QoS control device 120 gives priority to communication to the UE 211 of user U1. In this way, the QoS control device 120 controls to give priority to the wireless communication of the UE 211 of user U1 based on the student information 321 of the authenticated user. In this way, when the installation location of the camera 201 in the facility matches the user's location, the QoS control device 120 controls to give priority to the wireless communication of the UE 211.

[0029] For example, if user U1 is in the lecture room 200 for a lecture at the lecture time indicated in the student information 321 of that user, the QoS control device 120 determines that user U1 is attending the lecture appropriately. The QoS control device 120 controls the UE 211 to perform prioritized communication. On the other hand, since user U2 is not in the lecture room 200, the QoS control device 120 controls the UE 211 to perform normal communication. Alternatively, for a user attending a lecture for which the lecture QoS information 322 indicates normal communication, the QoS control device 120 controls the user terminal of that user to perform normal communication.

[0030] In this way, wireless communication can be controlled appropriately. Only users who are attending a lecture appropriately can communicate with priority. The communication control device 100 can prioritize communication only for users who are attending a lecture in a lecture room that is designated as prioritized communication. Users who are attending a lecture that is different from the lecture schedule indicated in the student information 321 will be subject to normal communication. Furthermore, user U2 outside the lecture room 200 and users in locations other than the lecture room 200 will be subject to normal communication. Users attending a lecture whose lecture QoS information 322 indicates as normal communication will be subject to normal communication. In this way, only users who are attending a lecture that is designated as prioritized communication in an appropriate lecture room can communicate at high speed. In this way, users can attend the lecture appropriately. Bandwidth congestion can be prevented in the communication system 1.

[0031] Alternatively, the camera 201 may repeatedly transmit facial information of the user U1. Then, when the user U1 leaves the lecture room 200, the UE 211 may return to normal communication. For example, the camera 201 captures a moving image of the user U1. Alternatively, the camera 201 captures a still image of the user U1 at regular time intervals. The camera 201 then periodically transmits the facial information to the communication control device 100. Upon receiving the facial information, the communication control device 100 performs facial authentication. In this manner, the communication control device 100 can periodically perform facial authentication.

[0032] If the facial authentication results do not match, the communication control device 100 switches the UE to normal communication. If the camera 201 cannot capture an image of the face or if facial authentication is not possible, the communication control device 100 switches the UE to normal communication. If facial authentication is not successful for a certain period of time, it may determine that the user is not in the lecture hall 200 and return the UE to normal communication. Alternatively, if facial authentication is successful using facial information from a camera installed outside the lecture hall 200, the UE 211 of user U1 may be placed in normal communication. Alternatively, if other sensors or means detect that user U1 is outside the lecture hall, the UE 211 may be placed in normal communication. The user's facial information may also be replaced by the user's student ID card.

[0033] Hereinafter, a control function for prioritizing communication for user U1 will be described. In the following description, each function will be described as being for a 5GC network, but this embodiment is not limited to a 5G network.

[0034] The PCF 130 is a function that performs policy control. The PCF 130 provides, for example, policy control for session management-related functions and policy control for access and mobility-related functions. The PCF 130 performs QoS control. Specifically, the PCF 130 sets prioritized communication or normal communication for each UE and notifies an SMF (Session Management Function) 501 and an AMF (Access and Mobility Management Function) 503.

[0035] The SMF 501 is a function for managing sessions. For example, the SMF 501 establishes, maintains, modifies, and releases PDU sessions. The SMF 501 also obtains information about the base station to which the UE 211 is connected from the AMF 503s.

[0036] The UPF (User Plane Function) 502 is one of the network functions in the 5GC user plane. The UPF 502 processes and forwards user data, allowing the UE 211 to access the campus network 500. The functionality of the UPF 502 is controlled by the SMF 501. For example, the UPF 502 prioritizes the transmission of data from the UE 211, which is prioritized communication.

[0037] The AMF 503 is a function that manages access and terminal mobility. The AMF 503 is one of the network functions within the 5GC control plane. The AMF 503 manages UE registration, connection, and mobility.

[0038] The gNB (next generation Node B) 504 is a base station of the 5G network. The gNB 504 includes a radio unit (RU), a transmission device, a power source, an antenna, and the like. The gNB 504 is connected to the 5G core network. Although only one gNB 504 is shown in the figure, multiple gNBs 504 may be provided.

[0039] The communication control device 100 assigns priority communication to the UE 211 based on the authentication result, the student information 321, the lecture QoS information 322, and the like. To this end, the PCF 130 notifies the SMF 501 of a change in the QoS policy. The SMF 501 requests the UPF 502 to prioritize communication of packets from the UE 211. This allows user U1, who is attending a lecture in the lecture room 200, to perform prioritized communication. Therefore, user U1 can attend the lecture without delay using the UE 211.

[0040] 4 is a diagram for explaining a control flow in the communication system 1. Note that, prior to the processing, a PDU session is established between the UE 211 and the UPF.

[0041] The camera 201 captures an image of the face of the user U1 (S1). The camera 201 transmits an image of the user U1 to the communication control device 100 (S2). The camera 201 transmits facial information of the user U1. The facial information may be image data of the face, or may be information extracted from the image data of the face.

[0042] When the communication control device 100 receives the face information, the authentication control device 110 requests the server 300 for student information (S3). The server 300 transmits the student information to the communication control device 100. As described above, the student information includes face photo data 312 and student ID number 311. The student information may also include the terminal ID of the user's UE.

[0043] When the communication control device 100 receives the student information, the authentication control device 110 performs user authentication (S5). The authentication control device 110 compares the facial information with the facial photograph data to determine whether they match. When user authentication is complete, the authentication control device 110 instructs the QoS control device 120 to change the QoS (S6). Here, the authentication control device 110 transmits the student ID number 311 of user U1 to the QoS control device 120. This student ID number 311 is the student ID number 311 obtained from the server 300 in S3.

[0044] The QoS control device 120 checks the schedule of the authenticated user (S7). The QoS control device 120 requests the student information 321 from the server 300 (S8). Here, the communication control device 100 transmits the student ID number of the authenticated user to the server 300.

[0045] When the server 300 receives the request, it transmits the attendance information to the communication control device 100 (S9). The attendance information is information including the student ID number, attendance result, and designated QoS. The attendance result is information indicating whether the lecture attended by the authenticated user is being held in the lecture room 200 in which the camera 201 is installed. The designated QoS is information specifying the QoS of the lecture. Specifically, the designated QoS is data indicating whether the lecture is a lecture using prioritized communication or normal communication.

[0046] If the authenticated user is currently taking the lecture, the QoS controller 120 changes the QoS to the designated QoS (S10). Therefore, the QoS controller 120 sends a QoS change request (Npcf_PolicyAuthorization_Create Request) to the PCF 130 (S11). This request includes the student ID number and the designated QoS. The QoS controller 120 then sends a response (Npcf_PolicyAuthorization_Create Response) to the PCF 130 to inform it that it has received the QoS change request (S12).

[0047] In the table shown in FIG. 4, the QoS information for the user with student ID number 002 is set to High. The SUPI (Subscription Permanent Identifier) ​​corresponds to the terminal ID of the UE. In other words, the SUPI is a user-specific identifier assigned to each user terminal. The SUPI for the UE with student ID number 002 is SUPI-B, and the session information is Session-B. The PCF 130 can identify the SUPI and session information of the UE 211 based on the student ID number of user U1.

[0048] The PCF 130 sends a QoS policy update request (Npcf_SMPolicyControl_UpdateNotify Request) to the SMF 501 so that Session-B will have the specified QoS (S13). The QoS policy update request includes session information and QoS information corresponding to the specified QoS. The SMF 501 responds to the PCF 130 (pcf_SMPolicyControl_UpdateNotify Response) to notify that it has received the QoS policy update request (S14).

[0049] The SMF 501 transmits a session modification request (Session_Modification Request) to the UPF 502. The UPF 502 responds to the SMF 501 with an N4_Session_Modification Response to notify that the session modification request has been received (S16). In this manner, the communication control device 100 can change the QoS of the PDU session. Therefore, the communication of Session-B becomes a prioritized communication, and the UE 211 of the user U1 can communicate with priority.

[0050] In this way, the communication control device 100 determines whether or not to perform prioritized communication based on the user's unique student ID number. The communication control device 100 can appropriately identify users for whom prioritized communication is to be performed. Since only appropriate students can communicate with priority, lectures can be conducted smoothly. The communication control device 100 can appropriately control wireless communication.

[0051] Embodiment 3 In the third embodiment, the camera 211a of the UE 211 captures the face of the user U1. That is, the camera 211a is used instead of the camera 201 installed in the lecture room 200. Since the other points are the same as those of the above-described embodiments except that the camera 211a of the UE 211 captures the image of the user U1, the description thereof will be omitted as appropriate.

[0052] The camera 211a of the UE 211 captures the face of the user U1. For example, the UE 211 is a smartphone, a laptop PC, or the like, and is equipped with the camera 211a. The camera 211a is installed around the display of the UE 211. Thus, the camera 211a captures the face of the user U1 who is using the UE 211. The camera 211a periodically captures still images of the user U1. Alternatively, the camera 211a captures moving images of the user U1. Similarly, the UE 212 has a camera 212a. The camera 212a captures images of the user U2.

[0053] The UE 211 and the UE 212 transmit face information to the communication control device 100. When the communication control device 100 receives the face information, the authentication control device 110 performs face authentication as described above. The communication control device 100 assigns the UE 211 of the user U1 to priority communication. Similarly, if the user U2 is attending a lecture that is to be assigned priority communication, the communication control device 100 may assign the UE 212 of the user U2 to priority communication.

[0054] In this way, it is possible to assign priority communication to UEs other than those in the lecture room 200. Therefore, it is possible to appropriately control wireless communication. Users can watch online classes or recorded videos without delay. The communication control device 100 can change the QoS of users attending classes outside the lecture room. Therefore, only users attending classes can perform priority communication. Alternatively, the communication control device 100 may acquire location information of the UE 211 and determine whether the UE 211 is in the lecture room 200. The communication control device 100 may assign priority communication to only users attending a lecture in the lecture room.

[0055] Embodiment 4 In the embodiment, whether or not to perform prioritized communication is determined depending on the area in the lecture room 200 where the user is located. Fig. 6 is a block diagram showing the overall configuration of a communication system 1 using the communication control device 100. A QoS policy is set depending on the area in the lecture room 200. In other words, the QoS policy is subdivided within one lecture room 200. Within the lecture room 200, a distinction is made between priority areas where prioritized communication is performed and non-priority areas (also called normal areas) where prioritized communication is not performed.

[0056] As shown in Fig. 6, users U1 to U4 are in a lecture room 200. User U5 is outside the lecture room 200. Users U1 and U3 are using UE211 and UE213, respectively. Users U2, U3, and U5 are using UE222, UE224, and UE225, respectively.

[0057] Lecture room 200 comprises areas A1 to A4. QoS is set for each of areas A1 to A4. Lecture QoS information 322 includes information indicating whether priority communication or normal communication is required for each of areas A1 to A4 of lecture room 200. For example, areas A1 and A3 of lecture room 200 are priority areas where priority communication is performed, while areas A2 and A4 are non-priority areas where normal communication is performed. Of course, the number of areas included in lecture room 200 is not limited to four, and may be two or more. In this way, server 300 divides lecture room 200 into multiple areas in advance and sets lecture QoS information 322 for each area.

[0058] The camera 201 captures an image of the lecture room 200. The communication control device 100 identifies the user area in the lecture room 200 where the user is located based on the face information. The communication control device 100 detects which area the user is located in based on the user's coordinates in the image, etc. For example, areas A1 to A4 are associated with pixel coordinates in the image, etc. Alternatively, multiple cameras 201 may be provided in the lecture room 200 to capture images of each area. For example, the first camera 201 has an angle of view corresponding to area A1. In this case, it can be detected that user U1, whose image is captured by that camera 201, is in area A1. The communication control device 100 may identify the user area where user U1 is located by other image processing.

[0059] If the user area in which a user is located is a priority area, the communication control device 100 controls the communication of the user terminal of that user to be prioritized. In Fig. 6, users U1 and U3 are in the priority area. Therefore, the communication control device 100 controls communication so that UE211 and UE213 perform prioritized communication. In this way, it is possible to more appropriately control wireless communication.

[0060] Furthermore, user U2 and user U4 are in areas A2 and A4, which are non-priority areas. Therefore, the communication control device 100 controls UE222 and UE224 to perform normal communication. Furthermore, user U5 is outside the lecture room 200. Therefore, the communication control device 100 controls UE225 to perform normal communication.

[0061] In the above description, the communication control device 100 switches the communication speed between two levels: prioritized communication and normal communication (non-priority communication). However, the communication speed may be switched between three or more levels. For example, the communication control device 100 may control communication so that high-speed prioritized communication, medium-speed prioritized communication, or low-speed normal communication is selected depending on the area. In this case, the lecture QoS information 322 may be divided into three or more levels. This allows the communication control device 100 to more appropriately control wireless communication.

[0062] Furthermore, the area setting may be changed depending on the time period within a lecture. For example, in the first half of the lecture, areas A1 and A3 may be priority areas, and in the second half of the lecture, areas A2 and A4 may be priority areas. In other words, in the first half of the lecture, areas A2 and A4 may be non-priority areas, and in the second half of the lecture, all of areas A1 to A4 may be priority areas. In this way, lecture QoS information 322 may be set so that the area setting changes within a single lecture. This allows the communication control device 100 to more appropriately control wireless communications.

[0063] 7 shows an example of the hardware configuration of a communication control device 100 according to some embodiments. In the example shown in the figure, the communication control device 100 includes a network interface 170, a processor 180, and a memory 190. Note that the UE 211, the server 300, and the like may also have a similar configuration.
