Description

Technical Field

[0001] The present disclosure relates to a wireless terminal device, a communication control method, a communication control program, and a base station. Background Art

[0002] In recent years, a variety of medical devices have been used in surgery, and multiple devices are now installed in operating rooms. Using wires to connect these devices complicates wiring and hinders movement of operating room components. Consequently, there is a demand for wireless medical devices. However, when multiple medical devices are wireless, multiple communication processes arise, and there is also the issue of reduced wireless connection stability.

[0003] Therefore, a method for stably performing communication by providing a plurality of transmission / reception units (antennas) for performing wireless communication has been proposed (for example, Patent Document 1). The technology described in Patent Document 1 proposes a configuration in which a plurality of transmission / reception units (antennas) are provided at the four corners of an operating table.

[0007] Technical issues

[0008] However, conventional technologies increase the number of components (devices) used for communication (such as antennas) to improve communication quality (such as connection stability), but this requires the addition of new devices, complicating the configuration. Furthermore, when antennas are attached to tools used in operating rooms (such as operating tables), installation work is required, which also increases costs. Therefore, it is desirable to improve the connection quality of communication between multiple medical devices without providing new devices.

[0009] Therefore, the present disclosure proposes a wireless terminal device, a communication control method, a communication control program, and a base station capable of improving the communication quality of wireless connection of medical devices arranged in a space of a medical institution.

[0062] [1-1. Overview of Communication Control Processing According to First Embodiment of the Present Disclosure]

[0063] Figure 1 : is a diagram showing an example of a communication control process according to the first embodiment of the present disclosure. Figure 11 is a diagram showing a configuration example of a communication control system 1 according to a first embodiment of the present disclosure. The communication control process according to the first embodiment of the present disclosure is performed by Figure 1 The communication control system 1 shown is implemented as follows. The communication control system 1 is a system that performs communication control based on quality of service (QoS).

[0064] First, we will describe Figure 1 The configuration of the communication control system 1 is shown. Figure 1 As shown, the communication control system 1 includes a base station 100 and a plurality of terminals 200. Figure 1 In the example shown, only two terminals 200 are shown: terminal 200-1 as terminal A and terminal 200-2 as terminal B, but the communication control system 1 may include three or more terminals 200, for example, terminal 200-3 as terminal C (refer to Figure 2 ) and terminal 200-4 as terminal D (refer to Figure 2 ). In addition, when terminals 200 - 1 to 200 - 4 and the like are not particularly distinguished from each other, they are collectively referred to as terminal 200 .

[0065] Terminal 200 is a wireless terminal device that wirelessly communicates with medical devices located within a medical facility. Terminal 200 can be any device that performs wireless communication, such as during surgery or in a medical setting. For example, Terminal 200 can include a pacemaker, particle therapy device, dialyzer, infusion pump, automated peritoneal perfusion system, artificial heart-lung system, multi-person dialysate supply system, etc. Terminal 200 can also include a blood component sampling device, a ventilator, an X-ray imaging device, an electrocardiograph, an ultrasound diagnostic device, an infusion pump for an infusion pump, catheter-related devices, a hearing aid, a home massager, a blood gas analyzer, etc. Furthermore, Terminal 200 can include a monitor, display, medical robot, endoscope, surgical light, hospital bed, nurse call system, IV-related devices, etc. In other words, the term "medical device" here encompasses a wide variety of devices used during surgery or in the medical field.

[0066] Figure 1 The example shows that the terminal 200 is arranged in an operating room (eg Figure 2 The terminal 200 performs wireless communication with another terminal 200 or the base station 100. Note that the terminal 200-1 is a monitor and the terminal 200-2 is a blood pressure meter. Figure 2 Detailed Description: In addition, the terminal 200 may be various devices, such as an IP converter, as long as it is a device that performs wireless communication with medical devices arranged in a space of a medical institution, and details of this will be described below.

[0067] The base station 100 is a device that provides wireless communication services to the terminal 200. The base station 100 is a device used for communication between the terminals 200. For example, the base station 100 is a base station that provides wireless communication services through a predetermined wireless communication system. For example, the wireless communication system is a fifth-generation mobile communication system (5G). Hereinafter, the wireless communication system will be described as a fifth-generation mobile communication system (5G). Note that as long as the communication control processing is applicable, the wireless communication system may be various cellular wireless communication systems such as the fourth-generation mobile communication system (4G), and a local wireless communication system technology such as Wi-Fi (registered trademark) may be used as the physical layer wireless communication. The base station 100 is connected to a space located in a medical institution (e.g. Figure 2 The base station 100 performs wireless communication with the terminal 200 in the operating room 5). For example, the base station 100 sends a downlink signal to the terminal 200 and receives an uplink signal from the terminal 200. For example, the communication control system 1 can be a system in which the above-mentioned cellular system (cellular wireless communication system) and the Wi-Fi system are combined. For example, the communication control system 1 can be a system in which 5G (fifth-generation mobile communication system) is integrated with Wi-Fi communication. In this case, in the communication control system 1, Wi-Fi communication is performed, and Wi-Fi resource control and the like can be performed by the base station 100.

[0068] The base station 100, the terminal 200-1 and the terminal 200-2 communicate with each other through wireless communications corresponding to a predetermined wireless communication system. Information is sent and received between the base station 100 and the terminal 200 through wireless communications corresponding to 5G. In addition, each terminal 200 sends information to and receives information from another terminal 200 through wireless communications corresponding to 5G. In addition, the terminal 200 may have a function of direct terminal-to-terminal communication. In this case, the terminal 200 allows direct communication between terminals while obtaining control support from the base station. The control from the base station includes, for example, allocation of wireless resources in a direct terminal-to-terminal communication link, transmission power control, provision of QoS control policies, interference control to another terminal, etc. In addition, when the base station does not exist, the terminal 200 can autonomously perform direct terminal-to-terminal communication. In this case, the control from the base station as described above cannot be obtained, but wireless sensing, etc. can be autonomously performed to establish a wireless communication link such as Wi-Fi communication. Note that, Figure 1 The communication control system 1 shown may include a plurality of base stations 100. In addition, the communication control system 1 is not limited to the base stations 100 or the terminals 200, but may include various components. For example, the communication control system 1 may include components such as a server, for example Figure 11The server 300 shown in FIG. For example, the server includes a core network such as an evolved packet core (EPC) or a 5G core. Note that the following will describe a case where the comprehensive QoS level, communication parameters, etc. are determined on the server side. The base station 100A enables connection to an external network via the core network.

[0069] First, the base station 100 obtains information related to QoS control (QoS control related information) from the terminal 200-1 as the terminal A (step S1). For example, the base station 100 sends a notification requesting QoS control related information to the terminal 200-1, and receives QoS control related information from the terminal 200-1. For example, when determining the type of message to be sent (type), the terminal 200 sends the message and the priority information corresponding to each message (QoS information) to the base station 100 as QoS control related information. The terminal 200-1 as a monitor sends the packet message type and respective priority information related to the monitor data to the base station 100. For example, the terminal 200-1 sends three types of packet message types and respective priority information to the base station (refer to Figure 7 ). Terminal 200-1 transmits priority information indicating that the priority (QoS level) of monitor message type #1 is "1", the QoS level of monitor message type #2 is "2", and the QoS level of monitor message type #3 is "3" to the base station. Note that the higher the level of a message type, the higher the importance (priority) of the message type. Note that parameters such as those standardized by 5G New Radio (NR) (e.g., QoS identifier (5GQI)) can be used here as QoS information.

[0070] In addition, the base station 100 obtains QoS control related information from the terminal 200-2 which is the terminal B (step S2). For example, the base station 100 sends a notification requesting QoS control related information to the terminal 200-2, and receives QoS control related information from the terminal 200-2. The terminal 200-2 which is the sphygmomanometer sends real-time data of the sphygmomanometer, and sends the group message type and respective priority information related to the sphygmomanometer to the base station 100. For example, the terminal 200-2 sends three types of group message types and respective priority information to the base station. The terminal 200-2 sends priority information to the base station indicating that the priority (QoS level) of the sphygmomanometer message type #1 is "1", the QoS level of the sphygmomanometer message type #2 is "2", and the QoS level of the sphygmomanometer message type #3 is "3".

[0071] The base station 100 that has obtained the QoS control related information generates an integrated QoS control table (step S3). For example, the base station 100 determines the integrated QoS level (importance level) based on the QoS control related information obtained from the terminal 200-1 and the terminal 200-2. Figure 1In the example of FIG, the base station 100 determines the comprehensive QoS level of three types of monitor message types #1 to #3 of the terminal 200-1 as a monitor and three types of blood pressure meter message types #1 to #3 of the terminal 200-2 as a blood pressure meter (refer to FIG Figure 4 ). The base station 100 determines the comprehensive QoS level, where monitor message type #1 is "1", blood pressure meter message type #1 is "2", monitor message type #2 is "3", blood pressure meter message type #2 is "4", monitor message type #3 is "5", and blood pressure meter message type #3 is "6".

[0072] In addition, the base station 100 generates a table for determining a method of controlling wireless communication parameters according to the integrated QoS level (integrated QoS level). The base station 100 determines wireless communication parameters for each of the integrated QoS levels "1" to "6". The base station 100 determines wireless communication parameters such as transmission power, allocated frequency resources, and coding rate. The base station 100 determines wireless communication parameters (refer to Figure 5 ), so that the higher the comprehensive QoS level, the greater the transmission power, the more frequency resources are allocated, and the better the coding rate.

[0073] Then, the base station 100 transmits information indicating the determined wireless communication parameters to the terminal 200-1 (step S4). The base station 100 transmits information indicating wireless communication parameters such as transmit power, allocated frequency resources, and coding rate to the terminal 200-1. For example, the base station 100 transmits information indicating the wireless communication parameters as communication policy information to the terminal 200-1. For example, the base station 100 transmits information indicating the message type corresponding to each integrated (aggregated) QoS level and information indicating the wireless communication parameters for each message type to the terminal 200-1. The terminal 200-1 obtains the information indicating the wireless communication parameters as communication policy information. For example, the terminal 200-1 obtains information indicating the message type corresponding to each integrated QoS level and information indicating the wireless communication parameters for each message type.

[0074] In addition, the base station 100 transmits information indicating the determined wireless communication parameters to the terminal 200-2 (step S5). The base station 100 transmits information indicating wireless communication parameters such as transmit power, allocated frequency resources, and coding rate to the terminal 200-2. For example, the base station 100 transmits information indicating wireless communication parameters to the terminal 200-2 as communication policy information. For example, the base station 100 transmits information indicating the message type corresponding to each integrated QoS level and information indicating the wireless communication parameters for each message type to the terminal 200-2. The terminal 200-2 obtains the information indicating the wireless communication parameters as communication policy information. For example, the terminal 200-2 obtains information indicating the message type corresponding to each integrated QoS level and information indicating the wireless communication parameters for each message type.

[0075] Then, the terminal 200 controls wireless communication based on the communication policy information (step S6). Each terminal 200 controls wireless communication based on the acquired communication policy information. Each terminal 200 controls wireless communication based on the acquired transmit power, allocated frequency resources, coding rate, etc. Each terminal 200 uses the acquired communication policy information to send a message to another terminal 200. Terminal 200 sends a message of the message type using the transmit power, allocated frequency resources, coding rate, etc. corresponding to the message type. Note that each terminal 200 can communicate directly with another terminal 200, or can communicate via base station 100. For example, base station 100 controls wireless communication between terminals 200 based on the communication policy information. Base station 100 controls wireless communication between terminals 200 by transmitting communication policy information to terminals 200 and enabling terminals 200 to communicate with each other based on the communication policy information. In addition, in the case of base station communication, for example, base station 100 uses wireless communication parameters corresponding to the message type of the message to transmit data (message) received from one terminal 200 to terminal 200 as the transmission destination.

[0076] For example, in conventional communications using unlicensed bands such as wireless LAN, when performing device-to-device communications, all communications are treated equally. On the other hand, in communications involving human life, such as those used for medical purposes, it is necessary to consider the priority of transmitted packets. In particular, in situations where high-priority life-threatening traffic is mixed with less critical traffic, it is crucial to implement control that prioritizes the high-priority traffic.

[0077] To achieve this control, wireless communication link control is required based on the services being transmitted. However, in medical device communications, priority control is difficult due to the lack of a common priority setting rule for each service. Therefore, a system is needed that establishes a common priority control system based on the service type between devices and controls wireless communication.

[0078] Therefore, the communication control system 1 can provide a wireless communication service that enables appropriate communication for each service priority by generating a comprehensive QoS table and uniformly controlling wireless communication links even between terminals 200 having different QoS tables. The communication control system 1 can improve the connection stability of the device based on QoS control, rather than increasing the number of receiving devices using short-range wireless terminals, etc.

[0079] [1-2. Example of Communication Control System Application in Operating Room]

[0080] The communication control system 1 performs control related to wireless communication of medical devices installed in a space of a medical institution such as an operating room. Figure 2 A case where the communication control system 1 performs control related to wireless communication with the terminal 200 in the operating room 5 will be described. Figure 2 1 is a diagram showing an example in which the communication control system according to the first embodiment is applied to an operating room.

[0081] like Figure 2 As shown, the communication control system 1 controls wireless communication in a private space such as an operating room of an operating room 5. For example, the communication control system 1 is provided with a dedicated base station 100 such as 5G or 4G in the operating room 5, and controls the wireless communication link. For example, the base station 100 may be provided near the ceiling of the operating room 5, such as Figure 2 As shown. For example, when performing communication using radio waves in a frequency band with high straightness, the base station 100 can be set near the ceiling. For example, in the case of wireless communication corresponding to 5G, the base station 100 can be set near the ceiling. Note that the base station 100 can be set in any location as long as it can control the wireless communication of the terminal 200 in the operating room 5.

[0082] exist Figure 2 In the example shown, the base station 100 and the lighting device 6 such as an operating lamp are arranged near the ceiling of the operating room 5. In addition, in the operating room 5, a terminal 200-1 as a monitor, a terminal 200-2 as a blood pressure meter, a terminal 200-3 as an endoscope, a terminal 200-4 as another monitor, etc. are arranged. Figure 2 In the example, for example, an operator 8 such as a doctor treats a patient (not shown) on an operating table 7.

[0083] For example, base station 100 controls communication between terminals 200. It controls wireless communication CM1 between terminals 200-2 and 200-3, which have a high overall QoS level, and wireless communication CM2 between terminals 200-1 and 200-4, which have a low overall QoS level. For example, base station 100 determines wireless communication parameters based on the overall QoS level and transmits information indicating the determined wireless communication parameters to each terminal 200, thereby controlling communication between terminals 200. For example, terminals 200-1 to 200-4 control wireless communication based on communication policy information, such as information indicating the wireless communication parameters.

[0084] For example, the logical entity (management entity) that performs wireless communication link control is not limited to the base station 100 and may be physically located on the server side, such as the core network. Furthermore, as described above, the wireless communication link may be direct communication (device-to-device communication) between devices (terminals 200), or may be downlink or uplink communication via the base station 100. The logical entity (management entity) performs wireless communication control on each link, depending on the QoS level of the service at each device (terminal 200).

[0085] Therefore, the base station 100 and the terminal 200 can improve the communication quality of wireless connections of medical devices installed in medical institution spaces such as operating rooms. In addition, the communication control system 1 can improve the communication quality of wireless connections, such as the connection stability of wireless connections of multiple medical devices in an operating room.

[0086] For example, when multiple medical devices in an operating room are wireless, assuming they communicate with a local communication base station (integrated communication control terminal) in the operating room, not all communications can be performed simultaneously because the communication band is a limited resource. In this case, packet loss or delays may occur during communication, reducing connection stability (communication quality), and information that the surgeon needs to view in real time may become invisible, potentially hindering the operation. Furthermore, since each of the multiple medical devices is sold by a different company, there is also the problem of difficulty in coordinating communications between the medical devices.

[0087] Therefore, the communication control system 1 performs QoS control using the local communication base station (base station 100). For example, the communication control system 1 prioritizes communications by inserting an adapter (wireless terminal) to achieve communication quality that does not interfere with surgical procedures. Furthermore, for local communication terminals, communication priorities can be determined by creating an entity table (a table that associates QoS levels, medical device types, and communication content types).

[0088] The communication control system 1 can reliably send high-priority packets to the destination by determining QoS (comprehensive QoS). Furthermore, since limited resources are used (orthogonal in time, space, and frequency and requiring scheduling), improving packet quality is important. Therefore, the communication control system 1 can improve communication quality (quality) by determining the priority (importance) of packets for each service. The communication control system 1 can improve communication quality by reducing packet loss (lowering packet error rate), reducing latency, increasing frequency allocation (increasing frequency band), and so on. Furthermore, the communication control system 1 can improve communication quality by performing extensive encoding on a small amount of data or increasing transmit power (increasing receive and transmit strength). Furthermore, by determining priorities as described above, the communication control system 1 can send certain communications with higher communication quality than other communications. For example, the communication control system 1 uses QoS levels (comprehensive QoS levels) to share frequencies, perform scheduling, and determine time occupancy. The communication control system 1 can perform communication control, such as switching communications in an unlicensed band to a licensed band. Furthermore, the communication control system 1 can perform link switching control via base stations and direct end-to-end communication links.

[0089] Through the above-mentioned control, the communication control system 1 can improve the communication quality. The communication control system 1 performs communication according to the communication policy information determined based on the QoS level. For example, in the case where the comprehensive QoS level is "1" to "5", the communication control system 1 determines the comprehensive QoS level to be "5" (maximum value) because the video of the endoscope needs to be displayed on the display device as little delay as possible. The communication control system 1 also determines the comprehensive QoS level of monitoring information such as heartbeat to be "5" (maximum value). In addition, because real-time performance is not required for communications such as the transmission of video from an operating room camera for capturing the surgical status or the transmission of recorded video of an endoscope (recorded and stored in a server), the communication control system 1 determines the comprehensive QoS level to be "1" (minimum value). By performing such processing, the communication control system 1 can reliably transmit information that requires real-time performance with very little delay and achieve communication quality that does not interfere with the progress of the operation.

[0090] [1-3. Configuration of Base Station According to First Embodiment]

[0091] Next, the configuration of the base station 100 according to the first embodiment will be described. Figure 3 is a diagram showing a configuration example of a base station according to the first embodiment.

[0092] like Figure 3 As shown, the base station 100 includes an antenna unit 110 , a communication unit 120 , a storage unit 140 and a control unit 150 .

[0093] The antenna unit 110 radiates the signal output from the communication unit 120 as radio waves into space. In addition, the antenna unit 210 converts the radio waves in space into signals and outputs the signals to the communication unit 120. For example, the antenna unit 110 includes an antenna for wireless communication.

[0094] The communication unit 120 transmits and receives signals. For example, the communication unit 120 transmits downlink signals to the terminal 200 and receives uplink signals from the terminal 200. The communication unit 120 wirelessly communicates with medical devices located in a medical facility. The communication unit 120 wirelessly communicates with medical devices located in an operating room.

[0095] The communication unit 120 is implemented by, for example, a network interface card (NIC), a communication circuit, etc. The communication unit 120 transmits information to the terminal 200 and receives information from the terminal 200 through wireless communication. In addition, the communication unit 120 can be connected to a predetermined network ( Figure 12 , and transmits and receives information to and from another device etc. via a predetermined network.

[0096] The storage unit 140 is implemented, for example, by a semiconductor memory element such as a random access memory (RAM) or a flash memory, or a storage device such as a hard disk or an optical disk. The storage unit 140 includes an integrated QoS information storage unit 141 and a communication parameter information storage unit 142. Note that the storage unit 140 stores not only the information indicated in the integrated QoS information storage unit 141 or the communication parameter information storage unit 142, but also various types of information. The storage unit 140 can store information collected from each terminal 200. For example, the storage unit 140 can store QoS-related information collected from each terminal 200.

[0097] The integrated QoS information storage unit 141 according to the first embodiment stores integrated QoS information. The integrated QoS information storage unit 141 stores various types of information on QoS obtained by aggregating QoS information collected from each terminal 200. Figure 4 is a diagram illustrating an example of an integrated QoS information storage unit according to the first embodiment. Figure 4 The integrated QoS information storage unit 141 shown includes items such as "QoS level after integration" and "QoS level of allocation source".

[0098] "QoS level after integration" indicates the QoS level after integration. "QoS level of distribution source" indicates the QoS level of the distribution source (i.e., the terminal 200 as the provider of QoS information). Figure 4In the example, it is assumed that the larger the value is, the higher the importance (priority) of the integrated QoS level and the assigned source QoS level is.

[0099] exist Figure 4 In the example of , the integrated QoS level "1" is indicated as corresponding to the QoS level "1" in terminal A (terminal 200-1). That is, the integrated QoS level of the message indicating the QoS level "1" sent by terminal A is "1". As described above, in Figure 4 In this case, the message with QoS level "1" sent by terminal A has the lowest priority.

[0100] In addition, the integrated QoS level "2" is indicated as corresponding to the QoS level "1" in the terminal B (terminal 200-2). That is, the integrated QoS level of the message indicating the QoS level "1" sent by the terminal B is "2". As described above, Figure 4 In this case, the message of QoS level "2" sent by terminal B has a higher priority than the message of QoS level "1" sent by terminal A.

[0101] In addition, the integrated QoS level "6" is indicated as corresponding to the QoS level "3" in the terminal B (terminal 200-2). That is, the integrated QoS level of the message indicating the QoS level "3" sent by the terminal B is "6". As described above, Figure 4 In this case, the message with QoS level "3" sent by terminal B has the highest priority.

"Allocated Frequency Resources (Number of Resource Blocks)" indicates the frequency resources allocated when transmitting a message of the corresponding combined QoS level. "Coding Rate" indicates the coding rate when transmitting a message of the corresponding combined QoS level.

[0105] exist Figure 4 In the example, the integrated QoS level "1" indicates that the transmission power is "30", the allocated frequency resources are "100", and the coding rate is "0.9". Figure 4 In this case, the message indication of QoS level "1" after comprehensive analysis has the lowest transmission power, fewer allocated frequency resources, and a poor coding rate.

[0106] After integration, the QoS level "2" indicates that the transmission power is "32", the allocated frequency resources are "200", and the coding rate is "0.7". Figure 4 In this case, it shows that the message of the comprehensive QoS level "2" has a larger transmission power, more allocated frequency resources and a better coding rate than the message of the comprehensive QoS level "1".

[0138] [1-5. Procedure of Communication Control Processing According to First Embodiment]

[0139] Next, we will refer to Figure 8 and Figure 9 The communication control process according to the first embodiment will be described. Figure 8 The flow of the learning process according to the first embodiment is described. Figure 8 is a flowchart showing the procedure of the communication control process according to the first embodiment.

[0140] like Figure 8 As shown, the terminal 200 acquires communication policy information determined by QoS information based on device information indicating the type of medical device and transmission information indicating the type of transmission content transmitted by the medical device (step S101). For example, the terminal 200 acquires communication policy information from the base station 100.

[0141] Terminal 200 controls wireless communication based on the communication policy information (step S102). Terminal 200 controls wireless communication based on the acquired transmit power, allocated frequency resources, coding rate, etc. Terminal 200 then wirelessly communicates with the medical devices located in the medical facility (step S103). Terminal 200 transmits a message of the message type using the transmit power, allocated frequency resources, coding rate, etc. corresponding to the message type.

[0142] Next, we will refer to Figure 9 Describe the entire processing flow. Figure 9 is a sequence diagram showing the procedure of the communication control process according to the first embodiment.

[0143] First, QoS-related control is performed on the base station 100 side. The base station 100 requests the terminal 200-1 as terminal A and the terminal 200-2 as terminal B to collect information related to QoS (step S201). For example, the base station 100 sends a notification of a request for QoS control-related information and obtains QoS control-related information from each terminal 200. The base station 100 sends a notification of a request for QoS control-related information to the terminal 200-1 (step S202). Therefore, the base station 100 sends a notification of a request for QoS control-related information to the terminal 200-1 (step S203). In response to the request notification, the terminal 200-1 notifies the base station 100 of the QoS-related information maintained in the terminal 200-1 as QoS control-related information (step S204). For example, when determining the type of message to be sent on the terminal 200-1 side, the terminal 200-1 sends the message and the priority information (QoS information) corresponding to each message to the base station 100.

[0144] In addition, the base station 100 sends a notification of a request for QoS control related information to the terminal 200-2 (step S205). Therefore, the base station 100 sends a notification of a request for QoS control related information to the terminal 200-2 (step S206). In response to the request notification, the terminal 200-2 notifies the base station 100 of the QoS related information maintained in the terminal 200-2 as QoS control related information (step S207). Note that the base station 100 can notify the terminal 200-1 and the terminal 200-2 of the request for QoS control related information at the same time, or can notify the terminal 200-2 of the request for QoS control related information before the terminal 200-1.

[0145] The base station 100 then generates an integrated QoS control (step S208). The base station 100 associates the service type generated in each device (terminal 200) with the wireless communication control corresponding to each service, and generates an integrated QoS control that is unified across the system. For example, the base station 100 determines an integrated QoS level and wireless communication parameters. The base station 100 then generates the information indicated in the integrated QoS information storage unit 121 or the information indicated in the communication parameter information storage unit 122 as the integrated QoS control.

[0146] Then, base station 100 sends an integrated QoS control to terminal 200-1 (step S209). Base station 100 sends information indicating the integrated QoS level or wireless communication parameters to terminal 200-1. Thus, terminal 200-1 obtains the integrated QoS control indicating the integrated QoS level or wireless communication parameters. Base station 100 sends an integrated QoS control to terminal 200-2 (step S210). Base station 100 sends information indicating the integrated QoS level or wireless communication parameters to terminal 200-2. Thus, terminal 200-2 obtains the integrated QoS control indicating the integrated QoS level or wireless communication parameters.

[0147] Then, when a service is generated (step S211), the terminal 200-1 performs transmission control according to the QoS (step S212). The terminal 200-1 performs communication control by using setting information such as wireless communication parameters set for each QoS level. The terminal 200-1 transmits a packet using wireless communication parameters (such as transmission power, allocated frequency resources, and coding rate) corresponding to the packet to be transmitted (step S213). Then, the terminal 200-2 receives the packet from the terminal 200-1 (step S214). Note that in Figure 9 In the example of , direct communication between the terminals 200 is shown as an example, but communication via the base station 100 is also handled in a similar manner.

[0148] [1-6. Overview of Communication Control Systems]

[0149] As described above, the communication control system 1 integrates the QoS level (rank) of each wireless service (packet) between multiple devices (terminals 200) and controls the wireless link according to the QoS level. As an example of the QoS level (rank), the level (rank) directly related to human life is set to the highest, the level (rank) related to human life but not significantly affecting human life is set to the second highest, and the level (rank) not related to human life is set to the lowest. For example, in the case where the importance level is set to a smaller value as it increases, the level (rank) directly related to human life is set to "1", the level (rank) related to human life but not significantly affecting human life is set to "2", and the level (rank) not related to human life is set to "3". In addition, for example, in the case where the importance level is set to a larger value as it increases, the level (rank) directly related to human life is set to "3", the level (rank) related to human life but not significantly affecting human life is set to "2", and the level (rank) not related to human life is set to "1". Note that the setting values ​​of the levels (ranks) described above are examples, and various values ​​can be set according to the number of levels (ranks), etc.

[0150] Furthermore, as examples of wireless communication control, the communication control system 1 performs control based on the priority of wireless links based on QoS, robust communication of communications with high priority, allocation of time-space frequency resources, transmission power control, modulation / demodulation control, etc. Furthermore, as examples of wireless communication control, the communication control system 1 can perform throttling of transmission of communications with low priority, time-frequency resource management, spatial interference control, etc.

[0151] Here, we will describe Figure 9 A specific example of the processing shown in . For example, the base station 100 sends a request for QoS control related information to terminal A, which is a monitor, or terminal B, which is a blood pressure monitor. Terminals A and B notify the base station 100 of the QoS control related information in response to the request from the base station 100. Terminal A sends the information of the video monitor to another monitor, and sends the packet message type and various priority information related to the monitor data to the base station 100. In addition, terminal B sends the real-time data of the blood pressure monitor, and sends the packet message type and various priority information related to the blood pressure monitor to the base station 100. On the base station 100 side, a comprehensive QoS table is generated using the obtained message type and priority information, and control of wireless communication is performed.

[0152] For example, assume that terminal A handles the transmission of monitor information, and terminal B transmits electrocardiogram information to the server. In this case, base station 100 understands the message contents from the control information and data information of terminals A and B, and identifies the transmitted monitor-related information and electrocardiogram information. In response, base station 100 generates a comprehensive QoS table and controls wireless communication.

[0153] [1-6-1. Comprehensive QoS Level]

[0154] The base station 100 that has obtained the QoS control related information generates Figure 4 The comprehensive QoS control table shown in FIG. For example, the base station 100 assigns the QoS level (importance level) to the QoS control related information in each device (terminal 200) as a whole, and controls the wireless communication service according to each importance level. For example, information such as importance levels 1, 2, and 3 is sent from device #1 (terminal A). Note that the higher the value, the higher the importance. In addition, information such as importance levels 1, 2, and 3 is sent from device #2 (terminal B). In this case, as Figure 4 As shown, the base station 100 uses various types of information to determine the overall importance level (overall QoS level).

[0155] [1-6-2. Wireless Communication Parameters]

[0156] The base station 100 generates a table for determining a method of controlling wireless communication parameters according to the integrated QoS level. The base station 100 determines wireless communication parameters, such as Figure 5 As shown in Figure 2. Note that regarding transmit power and resources, it is assumed that better parameters are allocated as the number increases. For the coding rate, a small value is a parameter that can achieve good performance.

[0157] Note that the setting policy for the integrated QoS level, the setting policy for the integrated QoS level, and the parameter allocation for wireless communication can be controlled separately by different policy control entities. For example, the controllable wireless communication parameters described below can be targets. The communication control system 1 can perform link switching, time-frequency resource allocation, and frequency band switching for base station-to-terminal communication and terminal-to-terminal communication. For example, the communication control system 1 can switch the frequency band from 2.4 GHz to 5 GHz. In addition, the communication control system 1 can switch the frequency band from an unlicensed band to a licensed band. The communication control system 1 can switch the frequency band from a licensed band to an unlicensed band.

[0158] In addition, the communication control system 1 can switch the transmission method (Tx diversity, multiple-input multiple-output (MIMO) transmission, beamforming weight change). For example, the communication control system 1 can perform link coordination. For example, the communication control system 1 can temporarily stop communication and secure resources for the prioritized link.

[0159] In addition, the communication control system 1 can change the modulation and coding rate. The change of modulation here can be switching between quadrature phase shift keying (QPSK), 16-bit quadrature amplitude modulation (QAM), etc.

[0160] Furthermore, the communication control system 1 can change the transmission power. For example, the communication control system 1 can switch the transmission module. If multiple modules are present, the communication control system 1 uses a specific module to switch the transmission point. Switching the transmission point includes switching distributed transmission points, switching physical antennas, and other methods. Switching the transmission point includes various methods for achieving spatial diversity.

[0161] Furthermore, the communication control system 1 can, in the event that any of the above-mentioned controls fails to satisfy the communication quality, alert the user of the notification system to the display and draw their attention to the display.

[0162] After generating the QoS control table, communication control system 1 configures each terminal 200 and controls wireless communication parameters based on each service. When a service is generated in terminal A, terminal A uses the generated service and the configured integrated QoS control table to configure parameters for wireless communication. After configuring wireless communication parameters, packet transmission is performed to enable transmission and reception with terminal B.

[0163] The communication control system 1 can generate a QoS table by including not only wireless communication services but also existing wired services such as DICOM. The control of the wireless communication parameters by the communication control system 1 can be to relatively control the parameters according to the QoS status of another communication link. For example, in a case where there are three links and two of the three links are packets with very high QoS, control can be performed so that the packet transmission of the remaining one link with low QoS is performed by multiplying a predetermined parameter by a predetermined weight value (weight A, etc.) and performing communication with lower performance. In addition, the congestion level of the frequency band, interference information from a specific link, etc. can be used to perform additional control on the wireless communication parameters, which will be described in detail below.

[0164] [1-6-3. QoS related information]

[0165] QoS-related information may include various types of information. For example, QoS-related information may include information such as transmission information. Transmission information may include various types of information related to a service, such as information indicating the service type and information indicating the purpose of the service. For example, transmission information may include information indicating whether the service type is voice, video, etc. For example, transmission information may include information indicating whether the purpose of the service is important data communication, backup processing, etc.

[0166] In addition, in the above example, the terminal 200 notifies the base station 100 of QoS related information in response to a request from the base station 100, but the base station 100 and the terminal 200 can obtain QoS related information through various means. For example, the base station 100 and the terminal 200 can obtain QoS related information such as QoS information by analyzing the transmission control information, data traffic, and packet information from the terminal 200 side on the base station 100 side, without sending a notification requesting QoS control related information.

[0167] For example, the base station 100 and the terminal 200 may obtain QoS control-related information by determining or extracting information. The base station 100 and the terminal 200 may extract QoS information from information related to data services. The base station 100 and the terminal 200 may use the information for specifying QoS information described below. The base station 100 and the terminal 200 may extract QoS information from information indicating what type of service exists, such as service type, service mode, and service cycle. For example, the base station 100 and the terminal 200 may extract QoS information from characteristics of transmission timing on a time axis, such as periodicity, aperiodicity, or event triggering.

[0168] In addition, the base station 100 and the terminal 200 can extract QoS information from information related to the purpose of the service and the message sent. For example, the base station 100 and the terminal 200 can read the data signal (message information) sent in the header of the packet, etc., and specify the purpose of the service based on the read information. The base station 100 and the terminal 200 can estimate the QoS information based on the service mode (periodic, non-periodic, event-triggered), the service size, and the size of the data sent. For example, the base station 100 and the terminal 200 can treat large data as important data. For example, the base station 100 and the terminal 200 can determine that the larger the data capacity, the higher the importance.

[0169] Furthermore, the base station 100 and the terminal 200 can determine (specify) QoS information based on the amount of traffic buffered. For example, information such as a buffer status report can be sent from the transmitting terminal 200 to the receiving terminal 200 to inform the receiving terminal 200 of the amount of traffic accumulated on the transmitting side. Thus, for example, when there is a large amount of buffering, the base station 100 and the terminal 200 can prioritize the traffic as data with high QoS.

[0170] In addition, the base station 100 and the terminal 200 can determine (specify) QoS information based on the delay request value of the service. For example, the base station 100 and the terminal 200 add the delay request value of the service to the packet header, etc., and determine the QoS based on this information. For example, when the delay request is strict, the base station 100 and the terminal 200 can set a high QoS. In addition, the base station 100 and the terminal 200 can determine (specify) QoS information based on the reliability request value of the service. For example, the base station 100 and the terminal 200 can add the reliability request value to the packet header, etc., and determine the QoS based on this information. For example, when the reliability request value is high, the base station 100 and the terminal 200 can set a high QoS.

[0171] Furthermore, the base station 100 and the terminal 200 can determine (specify) QoS information based on the service cycle. For example, service information can be pre-quantified into a score such as an importance level. The importance level can be used as QoS information associated with QoS. For example, a low importance level (e.g., 2) can be set for services such as monitor-to-monitor communication, and a high importance level (e.g., 8) can be set for services related to electric scalpel control.

[0172] Furthermore, for example, QoS control-related information may be exchanged (semi-)statically or dynamically between the terminal 200 and the base station 100. In the case of dynamic exchange, for each packet transmission, a notification of the priority information (QoS information) of the packet and information such as the degree of priority in the terminal 200 may be given. In the case of static exchange, the exchange may be performed at power-on (startup), etc., or in the case of semi-static exchange, the exchange may be performed periodically, for example, every few seconds.

[0173] [1-7. Conceptual diagram of the communication control system]

[0174] Here, we will refer to Figure 10 To conceptually describe each function, hardware configuration, and data in the communication control system. Figure 10 : is a conceptual diagram showing an example of a communication control system according to the first embodiment. Specifically, Figure 10 1 is a conceptual diagram showing an example of a communication control system in the case where an integrated QoS control table is generated on the base station 100 side. Figure 10 The illustrated communication control system corresponds to the communication control system 1 , and includes terminals 200 - 1 to 200 - 3 and a base station 100 .

[0175] The "adapter" in the base station 100 indicates a function for implementing wireless communication control. For example, the "adapter" corresponds to a function for comprehensive QoS setting for each service. For example, the function of the "adapter" corresponds to Figure 3The function of the determination unit 153 is shown.

[0176] The "Policy Control Entity" in base station 100 controls the "Adapter" and generates a comprehensive QoS table based on the QoS tables of terminals 200-1 through 200-3. For example, base station 100 corresponds to the entity that implements the wireless communication link. Base station 100 generates the comprehensive QoS control table through the "Adapter." Base station 100 uses the comprehensive QoS control table to control communications for terminals 200-1 through 200-3.

[0177] As mentioned above, in Figure 10 In the present invention, the base station 100 generates an integrated QoS control table in the system according to the instructions of the policy control entity by using the QoS list information in each terminal 200. Each terminal 200 controls the communication unit according to the set integrated QoS control table and the services generated by itself, and performs radio link control.

[0178] Note that the "policy control entity" may change the configuration (settings) according to the situation. For example, the "policy control entity" may change the settings according to the surgery, surgical content, or operation. For example, the "policy control entity" may change the settings according to time or place or a user such as a doctor (surgeon). The "policy control entity" may be set for each doctor. For example, the "policy control entity" may change the settings according to the device (terminal 200) in the network. For example, the "policy control entity" may change the settings according to the type or number of terminals 200 in the network and the available communication resources (frequency band, etc.). For example, the "policy control entity" may perform fixed operations or may change the settings dynamically.

[0179] [2. Second embodiment]

[0180] In the first embodiment described above, the case where base station 100 determines the comprehensive QoS level, wireless communication parameters, etc. has been described. However, the device that determines the comprehensive QoS level, wireless communication parameters, etc. is not limited to the base station and can be other devices. In the second embodiment, the case where server 300 determines the comprehensive QoS level, wireless communication parameters, etc. will be described as an example. Note that the description of the points that are the same as those of base station 100 and terminal 200 according to the first embodiment will be omitted as appropriate.

[0181] [2-1. Overview of Communication Control Processing According to Second Embodiment of the Present Disclosure]

[0182] First, refer to Figure 11 An overview of the communication control process according to the second embodiment is described. Figure 11 is a diagram showing an example of a communication control process according to the second embodiment of the present disclosure. Figure 11 The configuration of the communication control system 1A shown in FIG. Figure 11As shown, the communication control system 1A includes a base station 100A, a plurality of terminals 200, and a server 300. The base station 100A is communicably connected to the server 300 by wire or wireless via a predetermined network N (such as the Internet). The base station 100A transmits and receives information to and from the server 300.

[0183] Server 300 is an information processing device for providing wireless communication services. Server 300 uses information obtained from base station 100A to make various determinations. Server 300 determines the overall QoS level and communication parameters. For example, server 300 may be a core network such as an Evolved Packet Core (EPC).

[0184] First, the base station 100A obtains information related to QoS control (QoS control related information) from the terminal 200-1 as the terminal A (step S21). For example, the terminal 200-1 sends three types of packet message types and their respective priority information to the base station (see Figure 7 ). Terminal 200-1 transmits priority information indicating that the priority (QoS level) of monitor message type #1 is "1", the QoS level of monitor message type #2 is "2", and the QoS level of monitor message type #3 is "3" to the base station.

[0185] Furthermore, the base station 100A obtains QoS control-related information from the terminal 200-2, which is the terminal B (step S22). The terminal 200-2 transmits priority information to the base station indicating that the priority (QoS level) of the blood pressure meter message type #1 is "1", the QoS level of the blood pressure meter message type #2 is "2", and the QoS level of the blood pressure meter message type #3 is "3".

[0186] The base station 100A that has obtained the QoS control related information transmits the QoS control related information to the server 300 (step S23). The base station 100A transmits the QoS control related information obtained from the terminal 200-1 and the terminal 200-2 to the server 300.

[0187] After obtaining the QoS control-related information, server 300 generates a comprehensive QoS control table (step S24). For example, server 300 determines a comprehensive QoS level (importance level) based on the QoS control-related information of terminals 200-1 and 200-2. Server 300 determines a comprehensive QoS level for monitor message type #1 to be "1," blood pressure meter message type #1 to be "2," monitor message type #2 to be "3," blood pressure meter message type #2 to be "4," monitor message type #3 to be "5," and blood pressure meter message type #3 to be "6."

[0188] In addition, server 300 generates a table for determining a method for controlling wireless communication parameters based on the integrated QoS level (integrated QoS level). Server 300 determines wireless communication parameters for each of integrated QoS levels "1" to "6." Server 300 determines wireless communication parameters such as transmit power, allocated frequency resources, and coding rate. Server 300 determines wireless communication parameters such that higher integrated QoS levels result in greater transmit power, greater allocated frequency resources, and better coding rates.

[0189] The server 300 then transmits information indicating the determined integrated QoS level and wireless communication parameters to the base station 100A (step S25). Having received the information indicating the integrated QoS level and wireless communication parameters from the server 300, the base station 100A then transmits information indicating the wireless communication parameters to the terminal 200-1 (step S26). The base station 100A transmits information indicating wireless communication parameters such as transmit power, allocated frequency resources, and coding rate to the terminal 200-1. For example, the base station 100A transmits information indicating the message type corresponding to each integrated QoS level and information indicating the wireless communication parameters for each message type to the terminal 200-1. The terminal 200-1 obtains the information indicating the wireless communication parameters as communication policy information.

[0190] Furthermore, base station 100A transmits information indicating the determined wireless communication parameters to terminal 200-2 (step S27). Base station 100A transmits information indicating wireless communication parameters such as transmit power, allocated frequency resources, and coding rate to terminal 200-2. For example, base station 100A transmits information indicating the message type corresponding to each integrated QoS level and information indicating the wireless communication parameters for each message type to terminal 200-2. Terminal 200-2 acquires the information indicating the wireless communication parameters as communication policy information.

[0191] Then, the terminal 200 controls wireless communication based on the communication policy information (step S28). Each terminal 200 controls wireless communication based on the acquired communication policy information.

[0192] [2-2. Configuration of Base Station and Server According to Second Embodiment]

[0193] First, the configuration of a base station 100A that performs communication control processing according to the second embodiment will be described. Figure 12 is a diagram showing a configuration example of a base station and a server according to the second embodiment.

[0194] like Figure 12As shown, the base station 100A includes a communication unit 120, a storage unit 140, and a control unit 150A. The communication unit 120 includes a network communication unit that communicates with an external information processing device via a network N. The communication unit 120 communicates with the server 300 via the network N. In addition, the control unit 150A that does not include the determination unit 153 is different from the control unit 150 of the base station 100. Similar to the control unit 150, the control unit 150A is implemented by a CPU, MPU, etc. that executes a program (e.g., a communication control program according to the present disclosure) stored in the base station 100A using a RAM or the like as a work area. In addition, the control unit 150A can be implemented by an integrated circuit such as an ASIC or FPGA.

[0195] like Figure 12 As shown, the server 300 has the function of an "adapter". For example, Figure 12 The "Adapter" in Figure 10 The server 300 has a function similar to the function of the "adapter". Figure 3 The function of the determination unit 153 is shown.

[0196] Server 300 determines various types of information. Server 300 determines communication policy information based on device information indicating the type of medical device and QoS information indicating the type of content transmitted by the medical device. Server 300 determines communication policy information based on QoS information indicating the type of service. Server 300 determines communication policy information based on QoS information indicating the purpose of the service. Server 300 determines communication policy information based on QoS information indicating the service mode.

[0197] The server 300 determines communication policy information based on QoS information of the transmission information indicating the size of the service. The server 300 determines communication policy information based on QoS information of the transmission information indicating the buffering amount of the service. The server 300 determines communication policy information based on QoS information of the transmission information indicating the delay request value of the service. The server 300 determines communication policy information based on QoS information of the transmission information indicating the reliability request value of the service. The server 300 determines communication policy information based on QoS information of the transmission information indicating the reliability request value of the service. The server 300 determines communication policy information based on QoS information of the transmission information indicating the period of the service.

[0198] The server 300 determines the type of message to be sent to another device and determines the QoS of the message. The server 300 determines the QoS of the message through image recognition. The server 300 determines the QoS of the message based on the header information of the message. The server 300 determines the QoS of the message based on the metadata of the message. The server 300 determines the QoS of the message based on the DICOM-related information of the message. The server 300 determines the QoS level of the message.

[0199] [3. Third embodiment]

[0200] In the first and second embodiments described above, the case where the base station 100 or the server 300 determines the comprehensive QoS level, wireless communication parameters, etc. has been described, but the wireless terminal device may determine the comprehensive QoS level, wireless communication parameters, etc. Note that descriptions of points common to the above-described base stations 100 and 100A and terminal 200 will be omitted as appropriate.

[0201] [3-1. Overview of Communication Control Processing According to Third Embodiment of the Present Invention]

[0202] First, refer to Figure 13 , describing an overview of the communication control process according to the third embodiment. Figure 13 : is a diagram showing an example of a communication control process according to the third embodiment of the present disclosure. Specifically, Figure 13 : is a sequence diagram showing the procedure of the communication control process according to the third embodiment. Figure 13 1B is a diagram showing a configuration example of a communication control system 1B according to a third embodiment of the present disclosure.

[0203] First, we will describe Figure 13 The configuration of the communication control system 1B is shown in FIG. Figure 13 As shown, the communication control system 1B includes a base station 100B and a plurality of terminals 200B. Figure 13 In the example shown, only two terminals 200B are shown: terminal 200B-1 as terminal A and terminal 200B-2 as terminal B, but three or more terminals 200B may be included. In addition, when terminals 200B-1 to 200B-2, etc. are not particularly distinguished, they are collectively referred to as terminals 200B.

[0204] Similar to terminal 200, terminal 200B is a wireless terminal device that wirelessly communicates with medical devices located within a medical facility. For example, terminal 200B determines a comprehensive QoS level, wireless communication parameters, and other parameters. Then, when traffic is generated based on the comprehensive QoS control table and its own traffic, terminal 200B performs communication by setting transmission control parameters based on the comprehensive QoS table.

[0205] Similar to base station 100 and base station 100A, base station 100B is a device that provides wireless communication services to terminal 200B. Base station 100B is a device used for communication between terminals 200B. For example, base station 100B may include determination unit 153 like base station 100, or may not include determination unit 153 like base station 100A.

[0206] The base station 100B, the terminal 200B-1, and the terminal 200B-2 communicate with each other through wireless communication corresponding to a predetermined wireless communication system. The base station 100B and the terminal 200B send and receive information through wireless communication corresponding to 5G. In addition, each terminal 200B sends information to or receives information from another terminal 200B through wireless communication corresponding to 5G. Note that in Figure 13 The communication control system 1B shown in FIG may include a plurality of base stations 100B. In addition, the communication control system 1B is not limited to the base stations 100B or the terminals 200B, but may include various components. For example, the communication control system 1B may include a plurality of base stations 100B or the terminals 200B. Figure 11 The server and other components of the server 300 shown in FIG.

[0207] Hereinafter, the process of communication control processing will be described. In the communication control system 1B, a comprehensive QoS generation instruction is sent from the base station 100B side to the terminals 200B-1 and 200B-2, and the QoS table of each terminal 200B is updated. The base station 100B sends a comprehensive QoS generation instruction to the terminals 200B-1 and 200B-2 (step S301). The base station 100B side pre-generates a table of services and communication control in each terminal 200B, and sets the table in each terminal 200B. Figure 13 In the example of , the base station 100B generates a table of traffic and communication control in the terminal 200B, transmits the generated information to the terminal 200B-1 (step S302), and transmits the generated information to the terminal 200B-2 (step S303).

[0208] Then, in terminal 200B, wireless communication parameters are set through the set QoS control table and the services in terminal 200B. For example, terminal 200B generates a comprehensive QoS control. Terminal 200B-1 sets wireless communication parameters through the set QoS control table and the services in terminal 200B-1. For example, terminal 200B-1 determines the comprehensive QoS level based on the set QoS control table and the services of terminal 200B-1, and determines the wireless communication parameters based on the determined comprehensive QoS level. Terminal 200B-1 determines the comprehensive QoS level, wireless communication parameters, etc. Terminal 200B-1 generates comprehensive QoS information or information indicating wireless communication parameters as comprehensive QoS control (step S304). In this case, if the services of terminal 200B-1 do not correspond to the QoS control table, terminal 200B-1 can report to the base station 100B side and request correction of information (comprehensive QoS table, QoS control table, etc.).

[0209] Furthermore, terminal 200B-2 sets wireless communication parameters based on the configured QoS control table and the services of terminal 200B-2. For example, terminal 200B-2 determines an integrated QoS level based on the configured QoS control table and the services of terminal 200B-2, and determines wireless communication parameters based on the determined integrated QoS level. Terminal 200B-2 determines the integrated QoS level, wireless communication parameters, and the like. Terminal 200B-2 generates integrated QoS information or information indicating wireless communication parameters as integrated QoS control (step S305).

[0210] Note that not only can each terminal 200B generate an integrated QoS control, but a specific terminal 200B can also generate an integrated QoS control. For example, one terminal 200B can generate an integrated QoS control and send the generated integrated QoS control to each terminal 200B. In this case, as with the base station 100, one terminal 200B can obtain QoS-related information for each terminal 200, generate an integrated QoS control, and send the generated integrated QoS control to each terminal 200B. Note that the details of the case where one terminal 200B generates an integrated QoS control will be described below.

[0211] When a service occurs (step S306), the terminal 200B-1 performs transmission control according to the QoS (step S307). The terminal 200B-1 performs communication control by using the setting information (such as wireless communication parameters) set for each QoS level. The terminal 200B-1 transmits a packet using wireless communication parameters such as transmission power, allocated frequency resources, and a coding rate corresponding to the packet to be transmitted (step S308). Then, the terminal 200B-2 receives the packet from the terminal 200B-1 (step S309). It should be noted that in Figure 9In the example of , direct communication between the terminals 200B is shown as an example, but communication via the base station 100B is also handled in a similar manner.

[0212] [3-2. Configuration of Terminal According to Third Embodiment]

[0213] Next, the configuration of the terminal 200B according to the third embodiment will be described as an example of a wireless terminal device that performs communication control processing. Figure 14 : is a diagram showing a configuration example of a terminal according to the third embodiment. Figure 14 As shown, the terminal 200B includes a communication unit 220, a storage unit 240B, and a control unit 250B.

[0214] Similar to the storage unit 240, the storage unit 240B is implemented by, for example, a semiconductor storage element (such as RAM or flash memory) or a storage device (such as a hard disk or optical disk). The storage unit 240B includes a QoS information storage unit 241, a setting information storage unit 242, and an integrated QoS information storage unit 243.

[0215] The integrated QoS information storage unit 243 according to the second embodiment stores integrated QoS information. It should be noted that the information stored in the integrated QoS information storage unit 243 is the same as that stored in the integrated QoS information storage unit 243. Figure 4 The information in the integrated QoS information storage unit 141 shown in FIG. 1 is similar, and therefore a description thereof is omitted.

[0216] Similar to the control unit 250, the control unit 250B is implemented by, for example, a CPU, an MPU, or the like that executes a program (for example, a communication control program according to the present disclosure) stored in the terminal 200B using a RAM or the like as a work area. In addition, the control unit 250B can be implemented by, for example, an integrated circuit such as an ASIC or an FPGA.

[0217] like Figure 14 As shown, the control unit 250B includes an acquisition unit 251, a communication control unit 252, and a determination unit 253, and implements or executes the functions or operations of information processing described below. It is to be noted that the internal configuration of the control unit 250 is not limited to Figure 14 The configuration shown in , and may be other configurations as long as the information processing described below is performed.

[0218] The communication control unit 252 controls the wireless communication of the message based on the QoS determined by the determination unit 253. The communication control unit 252 controls the wireless communication of the message based on the QoS level determined by the determination unit 253.

[0219] Determining unit 253 determines communication policy information based on device information indicating the type of medical device and transmission information indicating the type of content transmitted by the medical device. Determining unit 253 determines communication policy information based on the QoS information of the transmission information, which indicates the type of service. Determining unit 253 determines communication policy information based on the QoS information of the transmission information, which indicates the purpose of the service. Determining unit 253 determines communication policy information based on the QoS information of the transmission information, which indicates the service mode. Determining unit 253 determines communication policy information based on the QoS information of the transmission information, which indicates the size of the service.

[0220] Determination unit 253 determines communication policy information based on QoS information of transmission information indicating the buffering amount of the service. Determination unit 253 determines communication policy information based on QoS information of transmission information indicating the delay request value of the service. Determination unit 253 determines communication policy information based on QoS information of transmission information indicating the reliability request value of the service. Determination unit 253 determines communication policy information based on QoS information of transmission information indicating the reliability request value of the service. Determination unit 253 determines communication policy information based on QoS information of transmission information indicating the period of the service.

[0221] Determination unit 253 determines the type of message to be sent to another device and determines the message's QoS. Determination unit 253 determines the message's QoS through image recognition. Determination unit 253 determines the message's QoS based on the message's header information. Determination unit 253 determines the message's QoS based on the message's metadata. Determination unit 253 determines the message's QoS based on DICOM-related information in the message. Determination unit 253 determines the message's QoS level.

[0222] [3-3. Conceptual diagram of the communication control system]

[0223] Here, we will refer to Figure 14 Conceptually describe each function, hardware configuration, and data in the communication control system. Figure 14 : is a conceptual diagram showing an example of a communication control system according to the third embodiment. Specifically, Figure 14 2 is a conceptual diagram showing an example of a communication control system in the case where an integrated QoS control table is generated on the terminal 200B side. Figure 14 The communication control system shown in corresponds to the communication control system 1B and includes terminals 200B- 1 to 200B- 3 and a base station 100B.

[0224] The "adapter" in the terminal 200B indicates a function for realizing wireless communication control. For example, the "adapter" corresponds to a function for setting a comprehensive QoS for each service. For example, the function of the "adapter" corresponds to Figure 14 The function of the determination unit 253 shown in FIG.

[0225] The "Policy Control Entity" in the base station 100B controls the "Adapters" of the terminals 200B-1 to 200B-3 and causes the terminals 200B-1 to 200B-3 to generate a comprehensive QoS table. For example, the terminals 200B-1 to 200B-3 generate a comprehensive QoS control table through the "Adapters". The terminals 200B-1 to 200B-3 use the comprehensive QoS control table to control communications. In this way, Figure 15 In the embodiment, only adapter control is controlled by the policy control entity from the base station 100 side, and the adapter control is used to convert the QoS list into an integrated QoS control table.

[0226] [4. Fourth embodiment]

[0227] In the third embodiment described above, the case where each medical device (terminal 200B) determines the comprehensive QoS level, wireless communication parameters, etc. has been described, but a predetermined wireless terminal device among the wireless terminal devices may determine the comprehensive QoS level, wireless communication parameters, etc. In addition, descriptions of points common to the above-described base stations 100, 100A, 100B and terminals 200, 200B are appropriately omitted.

[0228] [4-1. Configuration of Communication Control System According to Fourth Embodiment of the Present Disclosure]

[0229] First, the configuration of a communication control system 1C that executes a communication control process according to the fourth embodiment will be described. Figure 16 : is a diagram showing a configuration example of a communication control system according to a fourth embodiment of the present disclosure.

[0230] like Figure 16 As shown, the communication control system 1C includes a terminal 200B and a plurality of terminals 200. As described above, the communication control system 1C includes the terminal 200B that determines the comprehensive QoS level, wireless communication parameters, etc., and the plurality of terminals 200 that control communication based on the comprehensive QoS level, wireless communication parameters, etc. acquired from the terminal 200B. Figure 16In the example of FIG, a terminal 200B-20 as an IP converter, a terminal 200-21 as a surgical site camera, a terminal 200-22 as an endoscope, a terminal 200-23 as a microscope, a terminal 200-24 as a 4K monitor, a terminal 200-25 as a recorder (storage device), and a terminal 200-26 as a blood pressure monitor are shown. Note that the communication control system 1C is not limited to only six terminals 200: terminals 200-21 to 200-26, and may include various terminals 200. In addition, in Figure 16 The communication control system 1C shown in FIG. 1 may include a plurality of terminals 100B.

[0231] Terminal 200B-20 is an IP converter that wirelessly transmits various data and control signals such as 4K or high-definition (HD) video. Figure 16 In the example of FIG, terminal 200B-20 is a medical IP converter that wirelessly transmits data such as various videos inside and outside the operating room. Terminal 200B-20 transmits and receives information to and from terminals 200 (such as terminals 200-21 to 200-26) through wireless communication corresponding to 5G.

[0232] For example, terminal 200B-20, acting as an IP converter, converts various data into Internet Protocol (IP) and transmits the IP. Terminal 200B-20 is connected to various terminals 200 (such as terminal 200-24), including 4K medical devices, to enable wireless communication. It converts various data of video signals from input into IP for output, wirelessly transmitting video and control signals. Therefore, in the communication control system 1C, a simple system configuration can be implemented in the space of a medical institution (such as an operating room).

[0233] The terminal 200B-20 as an IP converter has an "adapter" function for realizing wireless communication control. The "adapter" in the terminal 200B-20 corresponds to a function for aggregating QoS settings for each service. For example, the "adapter" function corresponds to Figure 14 The function of the determination unit 253 of the terminal 200B shown in FIG. Figure 16 In the example shown in FIG, terminal 200B-20 requests terminals 200-21 to 200-26 to transmit QoS-related information and obtains QoS-related information from terminals 200-21 to 200-26. Terminal 200B-20 then generates an integrated QoS control using the QoS-related information of terminals 200-21 to 200-26 and transmits the generated integrated QoS control to terminals 200-21 to 200-26.

[0234] [5. Fifth embodiment]

[0235] Next, we will describe communication control for specific interference as an example of medical-specific communication control. In some of the embodiments described above, the terminal controls wireless communication parameters based on the transmitted packets and the integrated QoS table. However, additional wireless communication control can be performed on the base station side. For example, in medical facilities such as operating rooms, devices that are expected to interfere with other devices, such as electric scalpels, may be used, and even in environments where such interference occurs, it is necessary to ensure the quality of wireless communication.

[0236] Therefore, the communication control system can detect interference and perform communication control according to the interference. Figure 17 Describe this. Figure 17 : is a diagram showing a configuration example of a communication control system according to a fifth embodiment of the present disclosure. Figure 17 The example shows a case where the base station 100D performs interference detection and performs communication control, but the wireless terminal device can perform interference detection and perform communication control. Note that the description of the same points as the above-mentioned base stations 100, 100A, 100B and terminals 200, 200B will be appropriately omitted.

[0237] [5-1. Configuration of a communication control system according to a fifth embodiment of the present disclosure]

[0238] First, the configuration of a communication control system 1D that executes a communication control process according to the fifth embodiment will be described. Figure 17 is a diagram illustrating a configuration example of a communication control system according to a fifth embodiment of the present disclosure. Figure 17 Examples of additional control of wireless communication links for predictable interference are shown.

[0239] like Figure 17 As shown, the communication control system 1D includes a base station 100D and a plurality of terminals 200. Figure 17 In the example of FIG. 1 , only two terminals 200 are shown: the terminal 200 - 11 as an electric surgical knife and the terminal 200 - 12 as an electrocardiograph, but the communication control system 1D may include three or more terminals 200 .

[0240] Similar to the base station 100, the base station 100D is a device that provides wireless communication services to the terminal 200. Figure 17In the example, the base station 100D is connected to the terminal 200-11 as an electric scalpel through a predetermined interface IF. In addition, the base station 100D wirelessly communicates with the terminal 200-12 as an electrocardiograph through wireless communication RC corresponding to 5G. For example, the base station 100D determines the comprehensive QoS level, wireless communication parameters, etc. The base station 100D has the function of an interference detection unit that detects interference related to communication. In addition, the base station 100D can set a profile of an interference device that interferes with the terminal 200.

[0241] The control unit 150D (not shown) of the base station 100D is different from the control unit 150 of the base station 100. This control unit 150D includes a device operation detection unit 154 and an interference measurement unit 155. The base station 100D includes the interference measurement unit 155, which functions as an interference detection unit that detects interference related to communication. The communication control unit 152 of the base station 100D controls wireless communication based on the interference detected by the interference detection unit.

[0242] The device operation detection unit 154 detects an operation of the device (terminal 200). The device operation detection unit 154 acquires information indicating an operation performed by a user, for example, that an operation button of the device (terminal 200) has been pressed. The device operation detection unit 154 detects information generated by the operation of the device (terminal 200), for example.

[0243] The interference measurement unit 155 detects interference related to communication and measures the interference by appropriately using various technologies related to interference detection, etc. The interference measurement unit 155 changes the measurement frequency of the interference measurement unit according to the type of the operating device (terminal 200) or the operating state of the device (terminal 200). The interference measurement unit 155 performs interference measurement (terminal 200) every X ms, for example, when the target device (terminal 200) starts operating. For example, in the case of detecting interference from a specific type of device (terminal 200), interference measurement corresponding to the measurement frequency of the device (terminal 200) is performed. The interference measurement unit 155 changes the subsequent interference measurement frequency based on the interference detection result obtained first. The interference measurement unit 155 makes changes, for example, according to the interference level and interference pattern obtained first. As Figure 18 As shown, the interference measurement unit 155 generates a specific interference pattern for each device (terminal 200) and embeds information in the interference. Figure 18 : is a diagram showing an example of processing related to interference measurement according to the fifth embodiment. Specifically, Figure 18 An example of the generation of a specific interference pattern is shown.

[0244] exist Figure 18In the example of , the interference measurement unit 155 generates an interference pattern that represents initial interference characteristics. The interference measurement unit 155 generates an interference pattern that represents initial interference characteristics, as indicated at interference pattern PT1. The interference measurement unit 155 optimizes the measurement method. The interference measurement unit 155 optimizes the measurement method as indicated by target TG1.

[0245] Communication control unit 152 controls communication based on the information measured by interference measurement unit 155. Communication control unit 152 switches the frequency according to the information measured by interference measurement unit 155. Communication control unit 152 switches between the licensed band and the unlicensed band according to the information measured by interference measurement unit 155. Communication control unit 152 controls the transmission power according to the information measured by interference measurement unit 155. Communication control unit 152 increases the transmission power of the link to be protected according to the information measured by interference measurement unit 155.

[0246] Communication control unit 152 changes the coding rate based on the information measured by interference measurement unit 155. Communication control unit 152 increases the coding rate of the link to be protected based on the information measured by interference measurement unit 155. Communication control unit 152 performs repeated transmission based on the information measured by interference measurement unit 155. Communication control unit 152 enables retransmission for the link to be protected based on the information measured by interference measurement unit 155. For example, communication control unit 152 performs hybrid automatic repeat request (HARQ) transmission based on the information measured by interference measurement unit 155.

[0247] Communication control unit 152 changes the transmission scheme based on the information measured by interference measurement unit 155. Communication control unit 152 changes the transmission method of the link to be protected based on the information measured by interference measurement unit 155. For example, communication control unit 152 can perform processing for improving communication quality and reliability, so-called transmit diversity processing, based on the information measured by interference measurement unit 155. In addition, for example, communication control unit 152 can perform MIMO transmission based on the information measured by interference measurement unit 155.

[0248] The communication control unit 152 can perform priority control based on the information measured by the interference measurement unit 155. The communication control unit 152 reduces the communication quality of the link that is less in need of protection and improves the communication quality of the link to be protected based on the information measured by the interference measurement unit 155. The communication control unit 152 can change the packet transmission, mode change or resource allocation method based on the information measured by the interference measurement unit 155. The communication control unit 152 performs resource allocation based on the information measured by the interference measurement unit 155 to avoid the interference pattern of the device (terminal 200). The communication control unit 152 can switch from wireless communication to wired communication based on the information measured by the interference measurement unit 155. The communication control unit 152 switches to wired communication based on the information measured by the interference measurement unit 155. In addition, the communication control unit 152 can notify a person (such as an administrator of the communication control system 1D) of the necessity of switching.

[0249] For example, if significant interference (specific to medical devices) is predicted to occur with terminal 200-11, such as an electric scalpel, the communication control system 1D can perform wireless communication control in consideration of the predicted interference. The communication control system 1D detects the activation of a device that is believed to affect wireless communication, such as with an electric scalpel in an operating room environment, and predicts interference with the currently active wireless communication. Then, if interference is predicted, the communication control system 1D resets the transmit / receive control parameters used for wireless communication and implements wireless communication with high interference resistance. For example, the base station 100D of the communication control system 1D performs the aforementioned processing, such as detection and prediction.

[0250] The base station 100D takes measures against predictable interference. The device operation detection unit 154 of the base station 100D serves as a detection unit that detects the activation of a device (e.g., terminal 200-12, etc.) that may affect the wireless communication of the terminal 200-11, which is an electric scalpel, in an environment such as an operating room. In addition, the interference measurement unit 155 of the base station 100D serves as an interference prediction unit that predicts that the wireless communication being used will be interfered with. If interference is predicted to occur, the communication control unit 152 of the base station 100D resets the transmission / reception control parameters used for wireless communication and performs wireless communication with high anti-interference capabilities.

[0251] Furthermore, the above-described processing can be performed on the wireless terminal device side. In this case, the terminal 200, which serves as a wireless terminal device, includes an interference detection unit that detects interference related to communication. The interference detection unit detects interference related to communication and measures the interference by appropriately using various technologies related to interference detection, etc. For example, the terminal 200 may include an interference measurement unit 155 or a device operation detection unit 154 serving as an interference detection unit. The communication control unit 252 of the terminal 200 controls wireless communication based on the interference detected by the interference detection unit. Through the above-described processing, even in the case where interference is predicted to be generated by the terminal 200, the communication control system 1D can appropriately perform wireless communication control in consideration of the interference.

[0252] [6. Other embodiments]

[0253] The processing according to each of the above-described embodiments can be performed in various different forms (variations) other than the above-described embodiments. For example, in the above-described examples, the wireless terminal devices serving as base stations 100, 100A, 100B, and 100C and terminals 200 and 200B are separate entities, but the communication control system may include a wireless terminal device serving as a base station.

[0254] [6-1. Other configuration examples]

[0255] Here, as an example of communication control specifically for medical care, communication control for blocking wireless communication will be described. The terminal 200 controls wireless communication parameters based on the transmission packet and the integrated QoS table, but in addition to this, additional control of wireless communication can be performed on the base station 100 side. As described above, the communication control system can perform communication control corresponding to blocking wireless communication. This will be referred to Figure 19 To describe. Figure 19 : is a diagram illustrating a configuration example of a communication control system according to a modification example of the present disclosure.

[0256] exist Figure 19 In the illustrated operating room 5 , a plurality of antenna panels 61 are provided on a surgical lamp 60 . Figure 19 The case where four antenna panels 61-1 to 61-4 are arranged on the surgical light 60 is shown, but the number of antenna panels 61 arranged on the surgical light 60 is not limited to four. In addition, the antenna panel 61-5 is also arranged near the terminal 200-2. Figure 19 In the figure, it is assumed that four antenna panels 61-1 to 61-4, such as antenna panel 61-5, are arranged on surgical light 60. Note that when antenna panels 61-1 to 61-5, etc., are not specifically described separately, they are collectively referred to as antenna panels 61. Base station 100 uses antenna panels 61 to perform wireless communication. For example, base station 100 uses antenna panels 61 to perform wireless communication with terminal 200.

[0257] For example, Figure 19 In the illustrated operating room 5, a communication control system 1E determines the quality of the wireless link using antenna panels 61, which are multiple MIMO communication antennas connected to the ceiling, walls, surgical lights 60, and the like, based on line-of-sight (LOS) / non-line-of-sight (NLOS) conditions. For example, base station 100 determines the quality of antenna panels 61 based on LOS / NLOS conditions. In this case, base station 100 may include a unit that determines the quality of antenna panels 61 based on LOS / NLOS conditions.

[0258] The communication control system 1E then controls the activation / deactivation of the antenna panel 61 based on the LOS / NLOS determination of the antenna panel 61. For example, the communication control system 1E may identify the space and collectively control the indoor beamforming, or may learn the information. For example, the base station 100 may function as a beamforming management entity. The base station 100 controls the activation / deactivation of the antenna panel 61 based on the LOS / NLOS determination of the antenna panel 61. In this case, the base station 100 may include an operation control unit that controls the activation / deactivation of the antenna panel 61 based on the LOS / NLOS determination of the antenna panel 61. For example, the base station 100 may identify the space and collectively control the indoor beamforming, or may learn the information.

[0259] Therefore, the communication control system 1E can solve the problem of blockage of MIMO communication due to the head, body, etc. during operation, and can establish a stable and robust wireless communication link.

[0260] For example, Figure 19 The communication control system 1E shown learns the wireless communication link status and switches the communication link appropriately according to the obstacle behavior prediction before the blockage occurs. For example, the communication control system 1E may include components such as a server, such as Figure 11 The server 300 shown in FIG. In the communication control system 1E, the server side performs various types of control. The server performs information collection processing corresponding to the information collection block for learning. The server obtains position information between transmission and reception, 3D capture information of the operating room, position information of obstacles, and communication quality results for each communication link. For example, in order for the server to collect this information, a communication quality report of the base station 100 is set in the terminal 200.

[0261] The server performs learning processing corresponding to the learning block. The server determines the optimal link and beamforming setting information for each communication environment. The server performs prediction processing corresponding to the behavior prediction block. The server performs behavior prediction of mobile objects using a camera.

[0262] The server performs a determination process corresponding to the determination block. The server performs a determination on the necessity of link switching or beamforming setting information switching based on the behavior prediction information and the learning information.

[0263] The server performs processing corresponding to the link switching and beamforming configuration change blocks. The server issues instructions to activate / apply multiple transmitting nodes. The server executes beamforming configurations for use in the transmitting nodes. Note that the above-described server-side processing can also be performed by base station 100.

[0264] For example, Figure 19 The example shows a case where the base station 100 communicates with the terminal 200-3 using the antenna panel 61-3 among the plurality of antenna panels 61. Then, Figure 19 The example shows a case where the operator 8 blocks the communication with the terminal 200-3 through the antenna panel 61-3 due to the position movement of the operator 8, etc. Therefore, the base station 100 switches the communication with the terminal 200-3 through the antenna panel 61-3 to the communication through the antenna panel 61-4 or the communication through the antenna panel 61-5.

[0265] The communication control unit 152 of the base station 100 controls wireless communications based on the antenna positions. The communication control unit 152 of the base station 100 controls wireless communications using various technologies related to wireless communications. The communication control unit 152 of the base station 100 controls wireless communications using beamforming. The communication control unit 152 of the base station 100 controls wireless communications by switching the antenna panel 61 used for communications among the multiple antenna panels 61. For example, the communication control unit 152 of the base station 100 may select the antenna panel 61-4 with the highest reception strength among the multiple antenna panels 61 as the antenna to be used for communications, and perform wireless communications using the selected antenna panel 61-4.

[0266] The antenna unit 110 of the base station 100 may have multiple antennas for wireless communication. The communication control unit 152 of the base station 100 controls wireless communication based on the positions of the multiple antennas. The communication control unit 152 of the base station 100 controls wireless communication by switching the antenna used for communication between the multiple antennas.

[0267] Furthermore, the above-described processing can be performed on the wireless terminal device side. In this case, the communication control unit 252 of the terminal 200, which is the wireless terminal device, controls wireless communication based on the position of the antenna. The communication control unit 252 of the terminal 200 controls wireless communication through beamforming. The communication control unit 252 of the terminal 200 controls wireless communication using various technologies related to wireless communication.

[0268] The antenna unit 210 of the terminal 200 may have multiple antennas for wireless communication. The communication control unit 252 of the terminal 200 controls wireless communication based on the positions of the multiple antennas. The communication control unit 252 of the terminal 200 controls wireless communication by switching the antenna used for communication among the multiple antennas. The communication control unit 252 of the terminal 200 may select the antenna with the highest reception strength among the multiple antennas as the antenna used for communication and perform wireless communication using the selected antenna.

[0301] The input / output interface 1600 is an interface for connecting the input / output device 1650 and the computer 1000. For example, the CPU 1100 receives data from input devices such as a keyboard and a mouse via the input / output interface 1600. In addition, the CPU 1100 sends data to output devices such as a display, a speaker, a printer, etc. via the input / output interface 1600. In addition, the input / output interface 1600 can be used as a medium interface for reading programs recorded in a predetermined recording medium (medium). The medium is, for example, an optical recording medium such as a digital versatile disk (DVD), a phase-change rewritable disk (PD), a magneto-optical recording medium such as a magneto-optical disk (MO), a magnetic tape medium, a magnetic recording medium, a semiconductor memory, etc. For example, when the computer 1000 is used as the terminal 200 according to the embodiment, the CPU 1100 of the computer 1000 executes the information processing program loaded on the RAM 1200 to realize the functions of the control unit 250, etc. In addition, the HDD 1400 stores the information processing program and data according to the present disclosure in the storage unit 240.
