[0018] Fig. 2 is a diagram illustrating an example of a communication system in a roaming environment. As shown in Fig. 2, the network is composed of a UE, which is a terminal 20, and multiple network nodes 30. Hereinafter, it is assumed that one network node 30 corresponds to each function, but multiple functions may be realized by one network node 30, or multiple network nodes 30 may realize one function. Furthermore, the "connection" described below may be a logical connection or a physical connection.

[0019] The RAN 30A1 is a network node 30 having a radio access function, and is connected to the UE 20, the AMF 30B1, and the UPF 30C1. The AMF 30B1 is a network node 30 having functions such as RAN interface termination, NAS termination, registration management, connection management, reachability management, and mobility management. The UPF 30C1 is a network node 30 having functions such as a PDU session point to the outside that interconnects with the DN 30D1, packet routing and forwarding, and user plane QoS handling. The UPF 30C1 and the DN 30D1 constitute a network slice. In the wireless communication network according to the embodiment of the present invention, multiple network slices may be configured.

[0020] The AMF30B1 is connected to the UE 20, the RAN 30A1, the SMF30E1, the NSSF30F1, the NEF30G1, the NRF30H1, the UDM30I2, the AUSF30J2, the PCF30K1, the AF30L1, and the vSEPP30M1 (Security Edge Protection Proxy).

The vSEPP shown in FIG. 2 is a SEPP in the visited network, and the hSEPP is a SEPP in the home network.

[0022] As shown in Figure 2, the UE 20 is in a roaming environment connected to a RAN 30A1 and an AMF 30B1 in a Visited PLMN (VPLMN). The VPLMN and a Home PLMN (HPLMN) are connected via a vSEPP 30M1 and an hSEPP 30M2. The UE can communicate with a UDM 30I2 in the HPLMN via an AMF 30B1 in the VPLMN, for example.

[0023] In addition, in an NG-RAN (Next Generation Radio Access Network), a gNB, which is a RAN node, may have an architecture separated into a gNB-CU (Central Unit) and a gNB-DU (Distributed Unit). One gNB-CU may accommodate multiple gNB-DUs, and one gNB-DU may accommodate multiple cells.

[0024] With the advent of fifth-generation mobile communications (5G), it is now possible to increase the capacity and reduce latency of wireless cellular communications, and use cases for multiplexing and transmitting multiple types of data or packets are being widely considered and developed in society.

[0025] 3 is a diagram for explaining an example (1) of data transmission. FIG. 3 shows the configuration of data transmission for an application that transmits multiple types of packets as shown in Table 1.

[0026] [Table 1]

[0027] Table 1 shows packet types when an application performs remote robotic surgery support, as an example of a possible use case. The application transmits endoscopic video and robot information from the robot to the control side, transmitting, for example, two endoscopic video, audio, robot information, and other types of packets. As shown in Table 1, each type of packet has a different protocol, data volume, loss tolerance, delay tolerance, and delay jitter tolerance. Note that data volume may refer to communication speed, or may be the value obtained by dividing the data size by a unit of time.

[0028] Also, for example, when an application performs remote driving, the application transmits in-vehicle images, the vehicle's position, driving information, etc. from the vehicle to the control side, and transmits packets of various types, such as four in-vehicle images (front, rear, left, right), audio, and vehicle information.

[0029] If the wireless bandwidth during data transmission is smaller than the amount of data being transmitted, the packet processing method at the communication terminal or packet aggregation point may result in increased delay, delay fluctuations, and packet loss, which may affect the operation of applications.

[0030] Figure 4 is a diagram for explaining example (2) of data transmission. Between the communication terminal and base station shown in Figure 4, the wireless bandwidth varies depending on the location or time of day, and so the wireless bandwidth may become smaller than the amount of data to be transmitted. When the wireless bandwidth becomes smaller than the amount of data to be transmitted, the communication terminal and packet aggregation buffer and store packets so that they can be transmitted when the bandwidth is restored. Furthermore, if the bandwidth reduction continues for a long period of time, the amount of data of the accumulated packets exceeds the buffer capacity, and packets are discarded.

[0031] In the application receiving the packets, the packets are buffered on the sending side, which increases the packet delay and increases the delay fluctuation. Furthermore, discarding packets results in packet loss, making transmission impossible. This results in a degradation of the quality of service (QoS) and quality of experience (QoE).

[0032] 5 is a diagram illustrating an example (1) of data transmission according to an embodiment of the present invention. As described above, when the wireless bandwidth becomes smaller than the amount of data to be transmitted, all packets are affected, and delay fluctuations and the like may occur. Therefore, as shown in FIG. 5, the wireless bandwidth may be constantly estimated in the cloud, which is a relay point of data transmission, and notified to the packet aggregation side. In this way, when the wireless bandwidth becomes smaller than the amount of data to be transmitted, packets may be controlled and transmitted based on the priority set by the user at the packet aggregation point.

[0033] For example, if it is estimated that the wireless bandwidth will be smaller than the amount of data to be transmitted, control may be performed to enable stable transmission of one type of packet. Figure 5 shows an example in which packet B is stably transmitted by applying a priority control method in cooperation with the cloud in packet aggregation. On the other hand, packet A and packet X may be affected by packet loss, etc.

[0034] Fig. 6 is a diagram for explaining an example (2) of data transmission in an embodiment of the present invention. As a premise, the application in the use case has one type of packet with a high priority set by the user, and the priority remains unchanged during data transmission. The following operations 1, 2, and 3 may be executed. The application (transmission), packet aggregation, and communication terminal may be included in one device, for example, a terminal, or may be configured as separate devices.

[0035] 6, the cloud estimates fluctuations in the wireless band as operation 1. The cloud, which is a relay point for packet transmission, monitors the packet transmission status and estimates the degree of fluctuations in the wireless band.

[0036] As shown in Fig. 6, in operation 2, the cloud notifies the estimation result. As a priority control method in cloud cooperation, the cloud transmits the wireless bandwidth estimation result at regular intervals to a packet aggregation device located in the on-premises environment.

[0037] As shown in Figure 6, in operation 3, packet aggregation performs priority control based on the estimation result. Based on the wireless bandwidth estimation result notified from the cloud and the packet priority, packet aggregation performs priority control. Note that if the wireless bandwidth is larger than the amount of data to be transmitted, packet aggregation may transmit packets in FIFO (First In First Out) order.

[0038] Operation 1 will be explained below.

[0039] Fig. 7 is a diagram for explaining an example of a wireless band in an embodiment of the present invention. Fig. 8 is a diagram for explaining an example (3) of data transmission in an embodiment of the present invention. For example, as shown in Fig. 7, it is assumed that the wireless band fluctuates. Furthermore, data transmitted from packet aggregation is defined as 1) and 2) below.

[0040] 1) The maximum transmission data amount Dmax shown in FIG. 7 is the amount of data when all packets of an application are transmitted. 2) The minimum transmission data amount Dmin shown in FIG. 7 is the amount of data when transmitting only one type of packet that is prioritized by an application.

[0041] Table 2 shows an example of a data table corresponding to packet aggregation and the application shown in FIG. 8 that is pre-provisioned or configured in the cloud.

[0042] [Table 2]

[0043] As shown in Table 2, "control" is the packet type that has priority. In the example of Table 2, Dmax is 22.1 Mbps and Dmin is 1 Mbps. As shown in Figure 7, in a certain time period, the wireless bandwidth falls below the minimum transmission data amount Dmin.

[0044] Fig. 9 is a diagram illustrating an example (4) of data transmission in an embodiment of the present invention. Fig. 10 is a diagram illustrating an example (1) of the amount of data transmitted by a terminal in an embodiment of the present invention. Fig. 11 is a diagram illustrating an example (1) of the amount of data received by a cloud in an embodiment of the present invention. As shown in Figs. 10 and 11, the wireless band in the time domain is assumed to fluctuate. Steps 1) to 3) shown below may be performed.

[0045] Step 1) Data transmission is initiated from the application. The horizontal solid line in Fig. 10 indicates the amount of data transmitted from the packet aggregation. As shown in Fig. 10, at the start of transmission, the maximum amount of data may be transmitted in FIFO order.

[0046] Step 2) The cloud receives the data sent by the application, as shown in Figure 9. The cloud sorts the received data by packet type based on IP address and port.

[0047] Step 3) The cloud calculates the average amount of data Dave received over a certain period of time Tc. The horizontal dashed line in Figure 11 indicates the average amount of data Dave received over the Tc interval at the cloud. Dave = amount of data received over the Tc interval / Tc. The amount of data received for each type of packet is added together to calculate an estimated wireless bandwidth. Note that Tc may be set or changed as appropriate depending on the usage environment, etc.

[0048] Operation 2 will now be described.

[0049] Fig. 12 is a diagram illustrating an example (5) of data transmission in an embodiment of the present invention. Fig. 13 is a diagram illustrating an example (2) of the amount of data transmitted by a terminal in an embodiment of the present invention. Fig. 14 is a diagram illustrating an example (2) of the amount of data received by a cloud in an embodiment of the present invention.

[0050] As shown in FIG. 12, the average value of the amount of received data in the cloud is notified to a packet aggregation deployed in an on-premises environment. The content notified from the cloud to the packet aggregation may be a timestamp and the average value Dave of the amount of received data. The timestamp may be the time Tc in FIGS. 13 and 14, for example, 13:21:50.100. The average value Dave of the amount of received data may be the time Tc, for example, 20.453 Mbps. The timing at which the packet aggregation side acquires the timestamp and the average value of the amount of received data may be the time 2Tc.

[0051] 14, the average value of the amount of received data from time Tc to time 2Tc may be calculated in the cloud. The average value of the amount of received data from time Tc to time 2Tc may be acquired on the packet aggregation side at time 3Tc.

[0052] Note that time synchronization between the cloud and the packet aggregate may be required. The notification route, including the timestamp and the average amount of received data, includes the core network, wireless section (DL), communication terminal, and packet aggregate. Because the amount of data in the notification is extremely small, it may not have any impact on applications. The data size of the notification may be approximately 64 bytes, the same as a Ping. Since it takes several milliseconds to transmit the notification from the cloud to the packet aggregate, it may not be immediately reflected in priority control. For example, the packet aggregate may acquire the notification Tc after the time when the average amount of received data is calculated in the cloud.

[0053] Fig. 15 is a diagram illustrating an example of a configuration of packet control in an embodiment of the present invention. Fig. 16 is a diagram illustrating an example of packet control in an embodiment of the present invention. As shown in Fig. 15, packet aggregation may control packet transmission by a scheduler based on a notification from the cloud. In Pattern 1) to Pattern 3) shown in Fig. 16, the following control may be executed.

[0054] Pattern 1) Packet control when Dmax is equal to or less than Dave. In the scheduler, arriving packets may be transmitted in round robin or FIFO.

[0055] Pattern 2) This is packet control when Dmax is greater than Dave and Dave is equal to or greater than Dmin. The scheduler prioritizes incoming packets. For example, the scheduler may prioritize packets of a prioritized type so that they are transmitted 100% of the time, and transmit packets of other types in the remaining bandwidth so that they have equal opportunities to transmit.

[0056] Pattern 3) Packet control when Dmin is greater than Dave. The scheduler may transmit only priority packets and notify the application that the bandwidth is poor. Since there is a possibility that the wireless bandwidth will recover, it may be possible to continue transmitting only priority packets.

[0057] As an operation assuming the recovery of wireless bandwidth in the above Pattern 2 and Pattern 3, the scheduler may be configured so that 50% of data is always stored in the queue. The buffer in which this data is stored may be configured as a buffer dedicated to wireless bandwidth recovery and may be configured separately from the buffer for packet aggregation. When wireless bandwidth is recovered, the queue is released and becomes empty, so it is possible to gradually increase the amount of data to be transmitted, and to follow the recovery of wireless bandwidth.

[0058] FIG. 17 is a diagram illustrating an example of data transmission (3). FIG. 17 shows an example of the amount of data transmitted when general priority control is performed. For example, this may be the amount of data transmitted by a general router. As shown in FIG. 17, regardless of fluctuations in the wireless bandwidth, high-priority packets are always given priority and transmitted at the maximum data amount. When the wireless bandwidth suddenly drops, transmission can be performed so that the impact on high-priority packets is minimized. However, when the wireless bandwidth suddenly drops, high-priority packets may also be affected. When the wireless bandwidth recovers, tracking to the wireless bandwidth is not necessary, but high-priority packets may be affected depending on the amount of recovery. In FIG. 17, "large," "medium," and "small" indicate the degree of impact on packets due to bandwidth fluctuations. The degree of impact on packets includes packet loss, delay, fluctuation, etc.

[0059] FIG. 18 is a diagram illustrating an example (6) of data transmission according to an embodiment of the present invention. FIG. 18 shows an example of data transmission performed by switching between priority control and FIFO while tracking fluctuations in the wireless bandwidth. Even when the wireless bandwidth suddenly drops, high-priority packets can be transmitted stably compared to the data transmission in FIG. 17. However, the impact on other packets may be significant. When the wireless bandwidth recovers, the impact of another sudden drop in the wireless bandwidth can be reduced by gradually increasing the amount of data transmission to track the wireless bandwidth. In FIG. 18, "large," "medium," and "small" indicate the degree of impact on packets due to bandwidth fluctuations. The degree of impact on packets includes packet loss, delay, fluctuation, etc. Comparing the degree of impact on packets in FIG. 17 and FIG. 18, the degree of impact on priority packets is smaller in FIG. 18.

[0060] Fig. 19 is a diagram for explaining the case where Tc is small in the embodiment of the present invention. As shown in Fig. 19, when Tc is small, the ability to follow fluctuations in the wireless band improves. On the other hand, if the notification and system processing time exceeds Tc, the reflection of priority control may be delayed.

[0061] Fig. 20 is a diagram for explaining the case where Tc is large in an embodiment of the present invention. As shown in Fig. 20, when Tc is large, if the wireless bandwidth suddenly drops, it cannot keep up for a long period of time compared to when Tc is small, which may affect applications. Furthermore, when the wireless bandwidth recovers, the bandwidth utilization efficiency may decrease due to the low tracking ability.

[0062] The time required from the cloud to the packet aggregation to execute priority control in the packet aggregation is the sum of the time required to calculate the average value, the time required for notification, and the system processing time. Tc may be set by the user or based on the wireless environment, for example, LTE, 5G, or 6G.

[0063] According to the above-described embodiment, even if the wireless bandwidth is smaller than the amount of data to be transmitted, high-priority packets are stably transmitted based on the priority set by the user at the packet aggregation point. In other words, even if delay fluctuations or loss occur in other packets, data transmission according to the user's wishes can improve QoS (Quality of Service) and QoE (Quality of Experience).

[0064] That is, in an environment where the wireless band is narrow, the reliability of transmission of high-priority packets can be improved.

[0097] (Summary of the embodiment) As described above, according to an embodiment of the present invention, a communication device is provided that has a receiving unit that periodically receives from the network, with the unit time being a period, an average value of the communication speed related to data received by the network and transmitted by the device itself, and an end time of the unit time, and a control unit that executes transmission control of packets that make up the data based on the average value and the end time.

[0098] With the above configuration, even when the wireless bandwidth is smaller than the amount of data to be transmitted, high-priority packets are transmitted stably based on the priority set by the user at the packet aggregation point. That is, even if delay fluctuations or loss occur in other packets, QoS (Quality of Service) and QoE (Quality of Experience) can be improved by transmitting data according to the user's wishes. That is, in an environment where the wireless bandwidth is narrow, the reliability of transmission of high-priority packets can be improved.

[0099] The control unit may start the transmission control after the unit time has elapsed from the end time. With this configuration, even if the wireless bandwidth is smaller than the amount of transmission data, high priority packets are stably transmitted based on the priority set by a user at a packet aggregation point.

[0100] The control unit may perform control to transmit the packets in a round-robin manner when the average value is equal to or greater than the maximum communication speed of the transmission. With this configuration, even when the wireless bandwidth is smaller than the amount of data to be transmitted, packets with high priority are stably transmitted based on the priority set by a user at a packet aggregation point.

[0101] The control unit may perform control to transmit all of the packets having priority among the packets when the average value is less than the maximum communication speed of transmission and equal to or greater than the minimum communication speed of transmission. With this configuration, even when the wireless bandwidth is smaller than the amount of data to be transmitted, packets having high priority are stably transmitted based on the priority set by a user at a packet aggregation point.

[0102] The control unit may perform control to transmit only prioritized packets among the packets when the average value is less than the minimum communication speed for transmission. With this configuration, even when the wireless bandwidth is smaller than the amount of data to be transmitted, packets with high priority are stably transmitted based on the priority set by a user at a packet aggregation point.

[0103] As described above, according to an embodiment of the present invention, a communication method is provided in which a communication device executes the following steps: receiving, from the network periodically, an average value of the communication speed associated with data received by the network in a unit time and transmitted by the device itself, and the end time of the unit time, with the unit time being the cycle; and executing transmission control of packets constituting the data based on the average value and the end time.

[0104] With the above configuration, even when the wireless bandwidth is smaller than the amount of data to be transmitted, high-priority packets are transmitted stably based on the priority set by the user at the packet aggregation point. That is, even if delay fluctuations or loss occur in other packets, QoS (Quality of Service) and QoE (Quality of Experience) can be improved by transmitting data according to the user's wishes. That is, in an environment where the wireless bandwidth is narrow, the reliability of transmission of high-priority packets can be improved.

At least one of the base station and the mobile station may be a device that does not necessarily move during communication operations. For example, at least one of the base station and the mobile station may be an IoT (Internet of Things) device such as a sensor.

[0126] Furthermore, a base station in the present disclosure may be read as a user terminal. For example, the aspects / embodiments of the present disclosure may be applied to a configuration in which communication between a base station and a user terminal is replaced with communication between a plurality of terminals 20 (which may be called, for example, D2D (Device-to-Device) or V2X (Vehicle-to-Everything)). In this case, the terminal 20 may be configured to have the functions of the base station 10 described above. Furthermore, terms such as "uplink" and "downlink" may be read as terms corresponding to terminal-to-terminal communication (for example, "side"). For example, terms such as an uplink channel and a downlink channel may be read as a side channel.

[0127] Similarly, the user terminal in the present disclosure may be read as a base station, in which case the base station may be configured to have the functions of the user terminal described above.

[0128] As used in this disclosure, the terms "determining" and "determining" may encompass a wide variety of actions. "Determining" and "determining" may include, for example, judging, calculating, computing, processing, deriving, investigating, looking up, searching, inquiring (e.g., searching in a table, database, or other data structure), ascertaining, and the like.

Furthermore, "judgment" and "decision" can include regarding resolving, selecting, choosing, establishing, comparing, etc. as having been "judged" or "decided." In other words, "judgment" and "decision" can include regarding some action as having been "judged" or "decided." Furthermore, "judgment (decision)" can be interpreted as "assuming," "expecting," "considering," etc.

[0129] The terms "connected," "coupled," or any variation thereof, refer to any direct or indirect connection or coupling between two or more elements, and may include the presence of one or more intermediate elements between two elements that are "connected" or "coupled" to each other. The coupling or connection between elements may be physical, logical, or a combination thereof. For example, "connected" may be read as "access." As used in this disclosure, two elements may be considered to be "connected" or "coupled" to each other using one or more wires, cables, and / or printed electrical connections, as well as electromagnetic energy having wavelengths in the radio frequency range, microwave range, and optical (both visible and invisible) range, as some non-limiting and non-exhaustive examples.

[0130] The reference signal may be abbreviated as RS (Reference Signal) or may be called a pilot depending on the applicable standard.

[0131] As used in this disclosure, the phrase "based on" does not mean "based only on," unless expressly stated otherwise. In other words, the phrase "based on" means both "based only on" and "based at least on."

[0132] As used in this disclosure, any reference to an element using a designation such as "first," "second," etc. does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Thus, a reference to a first and a second element does not imply that only two elements may be employed or that the first element must in some way precede the second element.

[0133] The "means" in the configuration of each of the above devices may be replaced with "part," "circuit," "device," etc.
