[0032] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0033] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, the first object can be one or more. Furthermore, "or" in this application indicates at least one of the connected objects. For example, the scope of protection for "A or B" covers at least three scenarios: Scenario 1: including A but not B; Scenario 2: including B but not A; Scenario 3: including both A and B. In addition, the terms "A and / or B," "at least one of A and B," and "at least one of A or B" also cover at least the above three scenarios. The character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0034] The following explains the technologies involved in the embodiments of this application:

[0035] 1) In 5G systems (3rd Generation Partnership Project, Releases 15 or 16) of the 3rd Generation Partnership Project (3GPP), for audio (MMTEL voice) and video (MMTEL video) services (i.e., VoIP and Video) within Multimedia Telephony Voice (MMTEL), in scenarios with network air interface congestion, the base station (network-side equipment) can send a Media Access Control Element (MAC CE) to the terminal device. This MAC CE contains a recommended bit rate. The terminal device adjusts the data transmission rate based on the rate value contained in the MAC CE, essentially providing a suggestion for the maximum data transmission rate for a specific Logical Channel (LCH). Upon receiving this control information, the terminal device can pass it to the application layer for rate adjustment of application-layer data services. For example, for video services, the frame rate or bit rate can be adjusted to reduce the service rate. At the same time, this technology also allows terminal devices to report Recommended Bit Rate queries via MAC CE, inquiring whether the network can accept a certain rate adjustment.

[0036] 2) The 5th Generation System (5GS) core network publishes network information, which can help applications adjust media codecs or bandwidth rates in a timely manner. There are two standardization methods:

[0037] Explicit Congestion Notification (ECN) flags are used for ultra-low latency, near-zero packet loss, and high throughput (L4S):

[0038] L4S is an explicit congestion notification scheme. In 5GS, L4S can be used to mark L4S services with ECN so that congestion status can be quickly reported to applications through the user plane, which facilitates rate adaptation at the application layer.

[0039] NG-RAN is responsible for detecting congestion. NG-RAN or User Plane Function (UPF) performs ECN marking using the following options:

[0040] 1. NG-RAN performs congestion detection on the received data packets at the IP layer and marks the uplink and downlink data packets with ECN before sending the data packets to the terminal device and UPF.

[0041] 2. NG-RAN detects congestion in uplink or downlink traffic and sends the latest congestion information to UPF. Based on the received congestion reports, UPF marks the uplink and downlink IP layers of the received packets with ECN.

[0042] The term "instruction" in this application can be either a direct instruction (or explicit instruction) or an indirect instruction (or implicit instruction). A direct instruction can be understood as the sender explicitly informing the receiver of specific information, the required operation, or the requested result in the instruction sent. An indirect instruction can be understood as the receiver determining the corresponding information based on the instruction sent by the sender, or making a judgment and determining the required operation or requested result based on the judgment result.

[0043] It is worth noting that the technologies described in this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), or other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technologies can be used with the systems and radio technologies mentioned above, as well as with other systems and radio technologies. The following description describes New Radio (NR) systems for illustrative purposes, and the term NR is used in most of the following description; however, these technologies can also be applied to systems other than NR systems, such as 6th generation (6G) radio systems.th Generation 6G communication system.

[0047] The following description, in conjunction with the accompanying drawings, details the transmission rate adjustment method, terminal device, and network-side device provided in this application through specific embodiments and application scenarios.

[0048] The execution subject of the transmission rate adjustment method provided in this application embodiment can be a transmission rate adjustment device. Exemplarily, the transmission rate adjustment device can be an electronic device, or a functional component or entity within that electronic device. The electronic device in this application embodiment can be a terminal device; the following will use a terminal device as an example to executor the transmission rate adjustment method provided in this application embodiment.

[0049] Figure 2 This is a flowchart illustrating a transmission rate adjustment method provided in some embodiments of this application, such as... Figure 2 As shown, some embodiments of this application provide a transmission rate adjustment method that may include the following step 201.

[0050] Step 201: The terminal device adjusts its data transmission rate based on the rate adjustment information.

[0051] In some embodiments of this application, the terminal device is connected to at least two network-side devices.

[0052] In some embodiments of this application, the above-mentioned rate adjustment information includes a first rate value.

[0053] For example, the aforementioned rate adjustment information may be carried in Medium Access Control Element (MAC CE) signaling, or in RRC signaling, Non-Access Stratum (NAS) signaling, physical layer signaling, etc., and this application does not impose any restrictions.

[0054] In some embodiments of this application, the above-mentioned rate adjustment information is used to instruct the terminal device to adjust the data transmission rate according to a first rate value.

[0055] In some embodiments of this application, the above-mentioned rate adjustment information is determined based on the first rate information.

[0056] In some embodiments of this application, the first rate information mentioned above includes the rate information of at least one of the at least two network-side devices.

[0057] For example, the aforementioned rate information can be carried in MAC CE signaling, or in RRC signaling, NAS signaling, physical layer signaling, etc., and this application does not impose any restrictions.

[0058] In some embodiments of this application, the above-mentioned rate information is used to indicate the air interface data transmission status of the network-side device.

[0059] For example, the above-mentioned air interface data transmission status can be divided into network congestion status and network non-congestion status.

[0060] For example, the above-mentioned non-congested network state can be further divided into excellent network air interface state and good network air interface state.

[0061] In some embodiments of this application, the above-mentioned rate information includes, but is not limited to, at least one of the following: whether the rate needs to be adjusted, a second rate value, a quality of service flow identifier, a protocol data unit session identifier, the rate adjustment effective time, interface configuration, air interface congestion relief, and the terminal device querying the corresponding rate.

[0062] In some embodiments of this application, the above-mentioned at least one network-side device is a network-side device among at least two network-side devices.

[0063] For example, the first rate information mentioned above may include the rate information of one network-side device, or it may include the rate information of at least two network-side devices at the same time.

[0064] In some embodiments, the terminal device determines the rate adjustment information itself based on the rate information sent by at least two network-side devices, and adjusts the data transmission rate of the terminal device based on the first rate value in the rate adjustment information.

[0065] In some embodiments, the terminal device receives rate adjustment information sent by a network-side device and adjusts the data transmission rate of the terminal device according to a first rate value contained in the rate adjustment information, wherein the rate adjustment information is determined by the network-side device based on rate information from at least one other network-side device.

[0066] In the transmission rate adjustment method provided in this application embodiment, the terminal device adjusts its data transmission rate based on rate adjustment information. The terminal device is connected to at least two network-side devices. The rate adjustment information is determined based on first rate information, which includes the rate information of at least one of the at least two network-side devices. In this solution, the terminal device can determine the rate adjustment information based on the rate information of at least one network-side device in a scenario where it is connected to multiple network-side devices and at least one network-side device is in a network congestion state. This allows the terminal device to adaptively adjust its own data transmission rate, thereby solving the problem of poor data transmission efficiency caused by transmitting data at the original data transmission rate under network congestion conditions, and thus improving the data transmission efficiency of the terminal device.

[0067] In a first possible embodiment, the terminal device adjusts its data transmission rate according to the rate adjustment information sent by the first network-side device.

[0068] Furthermore, in some embodiments of this application, the transmission rate adjustment method provided in this application embodiment further includes step 301.

[0069] Step 301: The terminal device receives rate adjustment information from the first network-side device.

[0070] In some embodiments of this application, the aforementioned rate adjustment information is determined by a first network-side device based on first rate information.

[0071] In some embodiments of this application, the first rate information mentioned above includes the rate information of at least one of the at least two network-side devices.

[0072] In some embodiments, the first network-side device receives at least one rate information, namely the aforementioned first rate information, from at least one other network-side device. At this time, if the first network-side device detects that the air interface data transmission status of the first network-side device is in a network congestion state, the first network-side device determines rate adjustment information based on its own rate information and the received at least one rate information, and then sends the rate adjustment information to the terminal device.

[0073] In some embodiments, the first network-side device receives at least one rate information, namely the aforementioned first rate information, from at least one other network-side device. In this case, if the first network-side device detects that the air interface data transmission status of the first network-side device is in a non-congested network state, the first network-side device determines rate adjustment information based on the received at least one rate information. For example, it performs speed-up processing only on the second rate value contained in the rate information, and then sends the rate adjustment information to the terminal device.

[0074] In some embodiments, the first network-side device receives at least one rate information from at least one other network-side device. In this case, if the first network-side device detects that the air interface data transmission status of the first network-side device is in a non-congested network state and the network transmission status is very good, the first network-side device may choose not to send the received rate information.

[0075] It is understandable that the above steps constitute a network coordination process, where only one node (as mentioned above) sends a MAC rate control message, such as the first network-side device. Specifically, the details of network coordination include, for example, node 1 sending an inter-node message (including rate control-related information) to node 2. This information can include the aforementioned rate information, such as whether a rate adjustment is needed, a second rate value, a Quality of Service (QoS) flow identifier, a Protocol Data Unit (PDU) session identifier, the rate adjustment taking effect time, interface configuration, air interface congestion clearance, and terminal devices querying the corresponding rate, etc.

[0076] Specifically, for split bearers, negotiation information can be carried through the Xn interface, such as XnAP control plane signaling messages or Xn user plane GTP-U packet headers.

[0077] If XnAP control plane signaling messages are used, the following S-node modification procedure can be used.

[0078] For example, when the primary next-generation radio access network node (M-NG-RAN Node), such as the first network-side device mentioned above, experiences network congestion, the M-NG-RAN Node queries the secondary next-generation radio access network node (S-NG-RAN Node) via an S-node Modification Request message to inquire about the maximum rate that the S-NG-RAN Node air interface can support for a given QoS flow. The S-NG-RAN Node responds in the S-node Modification Request ACK. The M-NG-RAN Node calculates a suggested rate value based on corresponding rules and sends it to the terminal device. This rule can be the sum of two values, the maximum, the average, the minimum, or a random value within a range. If the secondary node (S-NG-RAN Node) is not congested, the M-NG-RAN Node can calculate a suggested rate value based on its desired rate adjustment or by subtracting a rate offset from its desired rate adjustment and send it to the terminal device. Another approach is for the M-NG-RAN node to inform the S-NG-RAN node of its (M-NG-RAN node's) rate limit when sending the S-Node Modification Request message, and instruct the S-NG-RAN node to calculate the target rate according to the calculation rules and notify the terminal device via MAC CE. These rules are the same as those described above.

[0079] When network congestion occurs in the S-NG-RAN node (i.e., the second network-side device mentioned above), the S-NG-RAN node base station (gNB) notifies the M-gNB of the required rate limiting value it needs to achieve via an S-node Modification required message. If the M-gNB determines that the corresponding air interface also requires rate limiting, it calculates a suggested rate value based on the rate information of the M-NG RAN node and the received S-NG RAN node rate information, according to corresponding rules, and sends it to the terminal device. This rule can be the sum, maximum, average, or minimum of two values, or a random value within a range. If the M-NG RAN node determines that the corresponding air interface is not congested, it can calculate a suggested rate value based on the S-NG RAN node rate information or by subtracting a rate offset from the S-NG RAN node rate information and send it to the terminal device. Alternatively, the S-NG RAN node requests the M-NG RAN node to send rate limits from the M-gNB. If the M-NG RAN node is congested and rate limiting is required, the M-gNB includes the corresponding rate in its S-NodeModification Confirmation message. The S-gNB, based on its own rate information and the received rate information from the M-NG RAN node, calculates a suggested rate value according to a corresponding rule and sends it to the terminal device. This rule can be the sum of two values, the maximum, the average, the minimum, or a random value within a range. If the M-NG RAN node determines that the corresponding air interface is not congested, the M-gNB includes a no-congestion indication in its S-Node Modification Confirmation message. The S-NG RAN node can calculate a suggested rate value based on its own rate information or by subtracting a rate offset from the S-NG RAN node's rate information and send it to the terminal device.

[0080] In addition, resource status request messages can be used to determine the rate limit of another network-side device, and then calculate and send it according to the rules.

[0081] In an architecture with F1 interfaces where the centralized unit and distributed unit (CU-DU) are separated, when air interface congestion occurs, the congested DU will notify the corresponding CU through a resource status update message or a g-NB-DU status indication message, and send a resource status request or a g-NB-DU resource coordination request to the DU corresponding to the other CU through another CU.

[0082] Next, when congestion is cleared, the two base stations exchange relevant information using a similar process. The difference lies in the fact that the sending gNB will choose whether to send a message to clear congestion or increase the allowed rate based on the air interface status of the two base stations. For example, if both are cleared, a message to clear congestion can be sent; if one is cleared and the other is not, the options are to clear congestion, increase the allowed rate, or not send a message to the terminal.

[0083] In this way, the terminal device can complete the rate adjustment operation simply by using the rate adjustment information sent by the first network-side device. Furthermore, since the first network-side device can negotiate and determine the rate adjustment information on its own, the terminal device's power consumption is reduced.

[0084] In a second possible embodiment, the terminal device receives first rate information, then determines rate adjustment information based on the first rate information, and then adjusts the data transmission rate of the terminal device based on the first rate value contained in the rate adjustment information.

[0085] Furthermore, in some embodiments of this application, the transmission rate adjustment method provided in this application further includes steps 401 and 402.

[0086] Step 401: The terminal device receives first rate information from at least two network-side devices.

[0087] In some embodiments of this application, the first rate information mentioned above includes the rate information of at least one of the at least two network-side devices.

[0088] In some embodiments, if the terminal device receives a predetermined number of rate information, it determines rate adjustment information based on all the received rate information, i.e., the aforementioned first rate information, and reports it to the application layer of the terminal device.

[0089] For example, the aforementioned predetermined quantity is determined according to the agreement or is a custom setting.

[0090] For example, the predetermined number may be the number of network-side devices connected to the terminal device.

[0091] For example, if a terminal device establishes a connection with two network-side devices, the predetermined number can be 2.

[0092] In some embodiments, when a terminal device receives rate information, it determines rate adjustment information based on that rate information, namely the aforementioned first rate information, and reports it to the application layer of the terminal device. That is, upon receiving rate information, a rate adjustment is determined, and the rate information is reported to the application layer.

[0093] In some embodiments of this application, the first rate information mentioned above is the rate information received by the terminal device within a preset duration of a first timer.

[0094] In some embodiments of this application, the preset duration of the first timer is determined according to the agreement or is a custom setting.

[0095] In some embodiments of this application, when the terminal device first receives rate information, a first timer is started. Then, after the first timer expires, the first timer is turned off, and the rate information received within the first timer is processed to determine whether to report it to the application layer. Alternatively, if a predetermined number of rate information messages are received before the first timer expires, the first timer is turned off, and the rate information received within the first timer is processed.

[0096] In some embodiments, if the terminal device receives a predetermined number of rate information within a preset duration of the first timer, it determines rate adjustment information based on all received rate information, i.e., the aforementioned first rate information, and reports it to the application layer of the terminal device.

[0097] For example, taking the preset duration of the first timer as 100ms and the preset quantity as 2, the terminal device has received two rate information at 70ms. At this time, the terminal device determines the rate adjustment information according to the two rate information, namely the first rate information mentioned above, and reports it to the application layer of the terminal device according to the predefined rules.

[0098] In some embodiments, if the terminal device does not receive a predetermined number of rate information within the preset duration of the first timer, rate adjustment information is determined based on the rate information, i.e., the aforementioned first rate information, and reported to the application layer of the terminal device.

[0099] For example, taking the preset duration of the first timer as 100ms and the preset quantity as 2, the terminal device receives only one rate information at 100ms. At this time, the terminal device determines the rate adjustment information based on this rate information, namely the first rate information mentioned above, and reports it to the application layer of the terminal device.

[0100] In some embodiments, if the terminal device does not receive a predetermined number of rate information within a preset duration of the first timer, all received rate information is discarded.

[0101] For example, if the preset duration of the first timer is 100ms and the preset quantity is 2, the terminal device will receive only one rate information at 100ms and will discard this rate information directly.

[0102] Step 402: The terminal device determines the rate adjustment information based on the first rate information.

[0103] In some embodiments of this application, the aforementioned rate adjustment information is determined by the terminal device based on the most recently received first rate information.

[0104] In some embodiments of this application, the aforementioned rate adjustment information is determined by the terminal device based on the first rate information most recently received within a preset duration of a second timer.

[0105] For example, when the terminal device first receives the rate information, a second timer is started, and then the second timer is turned off after it expires. Next, the rate adjustment information is determined from the last received rate information within the preset duration of the second timer, i.e., the aforementioned first rate information.

[0106] For example, if the preset duration of the second timer is 100ms, the terminal device will turn off the timer after 100ms. At this time, the terminal device will receive two rate information messages. The terminal device will then determine the rate adjustment information based on the last rate information received.

[0107] In some embodiments of this application, the above-mentioned rate adjustment information includes a first rate value.

[0108] In some embodiments of this application, the first rate information mentioned above includes the rate information of at least one of the at least two network-side devices.

[0109] In some embodiments of this application, each of the above rate information includes a second rate value.

[0110] In some embodiments of this application, the terminal device determines the first rate value in the rate adjustment information based on all the second rate values ​​contained in the first rate information.

[0111] In some embodiments of this application, the first rate value is any one of the following:

[0112] The maximum value among all second rate values ​​contained in the rate information;

[0113] The minimum value among all second rate values ​​contained in the rate information;

[0114] The average of the maximum and minimum values ​​among all the second rate values ​​contained in the rate information;

[0115] The average of all second rate values ​​contained in the rate information;

[0116] The random value among all the second rate values ​​contained in the rate information.

[0117] The sum of all second rate values ​​contained in the rate information.

[0118] For example, the above "sum of all second rate values ​​contained in the rate information" means that the terminal device adds up the second rate values ​​in all rate information and determines the sum as the above first rate value.

[0119] For example, the terminal device receives MAC rate control (i.e., the aforementioned rate information) from multiple network-side devices. The second rate value in this rate information indicates a rate that can be the highest rate allowed by each of the different network-side devices. Therefore, the terminal device sums the rates provided by the different network-side devices as the total QoS rate for the uplink service on this terminal device and notifies the application layer, ensuring that the uplink rate of the service does not exceed this rate value. Furthermore, based on the proportion of the highest rate provided by each network-side device, it reports corresponding Buffer Status Reports (BSRs) to the different network-side devices, or two independent BSRs plus a complete service BSR.

[0120] Specifically, base station 1 limits the data rate of the terminal device to 20kbps, and base station 2 limits the data rate of the terminal device to 30kbps. When the terminal device has 100K of data to be transmitted, it will send BSR=40K to base station 1 and BSR=60K to base station 2. Alternatively, the terminal device will report sub-BSR=40K and total BSR=100K to base station 1 and sub-BSR=60K and total BSR=100K to base station 2.

[0121] For example, the terminal device determines a specific value as the first rate value based on all the second rate values. This specific value can be the maximum value among all the second rate values, the minimum value among all the second rate values, the average value among all the second rate values, the average of the maximum and minimum values ​​among all the second rate values, or a random value among all the second rate values.

[0122] For example, the terminal device receives MAC CE rate control (i.e., the aforementioned rate information) from multiple network-side devices. The terminal device selects one value from these values, or calculates a value as the total QoS rate corresponding to this uplink service (i.e., the aforementioned first rate value), and notifies the application layer. For example, the rate information can be sent from the primary cell (Pcell) / master cellgroup (MCG), or configured cells. Both primary and secondary cells can also be configured. Further, the notification of which base station rate information to activate can be done via DCI or MAC CE dynamic activation. Here, the network-side devices can also interact with their respective air interface rate limits according to the interaction method in the first possible embodiment, and each send the value to the terminal device. The sent value can be its own value, the sum of two values, the average of two values ​​and its own value, or any value.

[0123] In this way, the terminal device can determine the first rate information according to different strategies, and determine the rate adjustment information containing the first rate value based on the rate value contained in the first rate information, so that the terminal device can adaptively adjust the current data transmission rate, thereby improving the efficiency of data transmission by the terminal device under network congestion.

[0124] Optionally, in some embodiments of this application, the transmission rate adjustment method provided in this application embodiment further includes step 601.

[0125] Step 601: The terminal device receives at least one congestion relief indication message from at least two network-side devices.

[0126] In some embodiments of this application, the above-mentioned congestion relief indication information is used to indicate that the network congestion state has been relieved.

[0127] In some embodiments, the aforementioned network congestion relief indication information is used to indicate to the network-side device that sent the network congestion indication information that the network congestion state has been relieved.

[0128] In some embodiments, the aforementioned network congestion relief indication information is used to indicate that all network-side devices connected to the terminal device have been freed from network congestion.

[0129] In some embodiments, the aforementioned network congestion relief indication information is used to indicate to a designated network-side device that the network congestion state has been relieved.

[0130] In some embodiments of this application, the terminal device will report the received congestion relief instruction information to the application layer of the terminal device.

[0131] In some embodiments, if the terminal device receives a predetermined number of congestion relief indication messages, it reports all received congestion relief indication messages to the application layer of the terminal device.

[0132] In some embodiments, upon receiving any congestion relief instruction information, the terminal device reports the congestion relief instruction information to the application layer of the terminal device.

[0133] Optionally, in some embodiments of this application, step 601 above can be specifically implemented by step 601a below.

[0134] Step 601a: The terminal device receives at least one congestion relief indication message from at least two network-side devices within a preset duration of the third timer.

[0135] In some embodiments of this application, the preset duration of the third timer is determined according to the agreement or is a custom setting.

[0136] In some embodiments of this application, when the terminal device first receives congestion relief indication information, a third timer is started. Then, after the third timer expires, the third timer is closed, and the congestion relief indication information received within the third timer is processed to determine whether to report it to the application layer. Alternatively, if a predetermined number of congestion relief indication messages are received before the third timer expires, the third timer is closed, and the congestion relief indication information received within the third timer is processed.

[0137] In some embodiments, if the terminal device receives a predetermined number of congestion relief indication messages within a preset duration of the third timer, it reports all received congestion relief indication messages to the application layer of the terminal device.

[0138] For example, taking the third timer with a preset duration of 100ms and a preset quantity of 2, the terminal device has received two congestion relief indication messages at 70ms. At this time, the terminal device reports these two congestion relief indication messages to the application layer of the terminal device.

[0139] In some embodiments, if the terminal device does not receive a predetermined number of congestion relief indication messages within a preset duration of the third timer, it reports all received congestion relief indication messages to the application layer of the terminal device.

[0140] For example, taking the third timer's preset duration of 100ms and the preset quantity of 2 as an example, the terminal device receives only one congestion relief indication message at 100ms. At this time, the terminal device reports this congestion relief indication message to the terminal device's application layer.

[0141] In some embodiments, if the terminal device does not receive a predetermined number of congestion relief indication messages within a preset duration of the third timer, all received congestion relief indication messages are discarded.

[0142] For example, taking the third timer's preset duration of 100ms and the preset quantity of 2 as an example, if the terminal device receives only one congestion relief indication message at 100ms, the terminal device will discard this congestion relief indication message directly.

[0143] In this way, the terminal device can adaptively inform the application layer of the congestion relief instruction information, so that the terminal device can speed up in a timely manner after the network congestion is relieved, thereby ensuring the data transmission rate of the terminal device.

[0144] Optionally, in some embodiments of this application, the transmission rate adjustment method provided in this application embodiment further includes step 701.

[0145] Step 701: The terminal device sends a speed adjustment query message to at least one third network-side device.

[0146] In some embodiments of this application, the aforementioned at least one third network-side device is some or all of the network-side devices connected to the terminal device.

[0147] In some embodiments of this application, the aforementioned third network-side device is the network-side device that relieves congestion among at least two network-side devices corresponding to rate information.

[0148] In some embodiments of this application, the speed regulation query message includes a third rate value.

[0149] In some embodiments of this application, the aforementioned speed adjustment query message is used to query whether the third network-side device accepts the third rate value.

[0150] For example, the above-mentioned query response message can be carried in MAC CE signaling, or it can be carried in RRC signaling, NAS signaling, physical layer signaling, etc., and this application does not impose any restrictions.

[0151] In some embodiments of this application, the third rate value is the sum of the rate values ​​required by the terminal device for the service to be transmitted.

[0152] In some embodiments of this application, the aforementioned third rate value is determined based on the rate ratio configured for the terminal device by some or all of the third network-side devices in at least one third network-side device.

[0153] For example, if the data rate required for the book-opening service of the terminal device is 100kbps, and the data rate ratio configured for the two connected network devices is 2:3, then the terminal device sends a data rate query message containing 40kbps data rate information to base station 1 and a data rate query message containing 60kbps data rate information to base station 2.

[0154] Optionally, in some embodiments of this application, step 701 above can be specifically implemented by step 701a below.

[0155] Step 701a: The terminal device sends a speed adjustment query message to the configured fourth network-side device.

[0156] In some embodiments of this application, the aforementioned fourth network-side device is one of at least one third network-side device.

[0157] In other words, the agreement stipulates that terminal devices are restricted to sending speed adjustment query information to only one network-side device.

[0158] Optionally, in some embodiments of this application, the transmission rate adjustment method provided in this application embodiment further includes step 801.

[0159] Step 801: The terminal device receives an inquiry response message from a third-party network device.

[0160] In some embodiments of this application, when an inquiry response message indicates that a third network-side device accepts a third rate value, the terminal device adjusts its data transmission rate based on the third rate value.

[0161] For example, the above-mentioned query response message can be carried in MAC CE signaling, or it can be carried in RRC signaling, NAS signaling, physical layer signaling, etc., and this application does not impose any restrictions.

[0162] For example, the above query response message can be understood as the above rate adjustment information.

[0163] It should be noted that the embodiments involved in steps 701 to 801 above can be implemented before or after step 201. Specifically, when speed adjustment is required, the terminal device can send a speed adjustment query message to the network-side device. After receiving the speed adjustment query message, the network-side device sends rate adjustment information or rate information to the terminal device, causing the terminal device to adjust the data transmission rate. Alternatively, after adjusting the data transmission rate, if the terminal device wants to adjust the speed again, it sends a speed adjustment query message to the network-side device to perform subsequent rate adjustment steps.

[0164] In this way, the terminal device can use a rate adjustment query message to inquire with the network side whether the network congestion has been resolved, or whether the terminal device can be allowed to transmit data at a third rate value. This allows the terminal device to adjust its data transmission rate in a timely manner, thereby ensuring the efficiency of data transmission.

[0165] The electronic device in this application embodiment can be a first network-side device. The following will take the execution subject as the first network-side device as an example to illustrate the transmission rate adjustment method provided in this application embodiment.

[0166] Figure 3 This is a flowchart illustrating a transmission rate adjustment method provided in some embodiments of this application, such as... Figure 3 As shown, some embodiments of this application provide a transmission rate adjustment method that may include steps 2001 to 2003.

[0167] Step 2001: The first network-side device receives at least one rate information from at least one second network-side device.

[0168] In some embodiments of this application, the aforementioned rate information comes from a second network-side device.

[0169] In some embodiments of this application, the first network-side device and at least one second network-side device are both network-side devices connected to the terminal device.

[0170] For example, the aforementioned rate information can be carried in MAC CE signaling, or in RRC signaling, NAS signaling, physical layer signaling, etc., and this application does not impose any restrictions.

[0171] Step 2002: The first network-side device determines the rate adjustment information based on the first rate information.

[0172] In some embodiments of this application, the first rate information mentioned above includes the rate information of at least one of the at least two network-side devices.

[0173] In some embodiments of this application, the first network-side device determines the first rate information based on the received rate information and the air interface data transmission status of the first network-side device, and determines whether to send rate adjustment information.

[0174] Furthermore, in some embodiments of this application, step 2002 described above can be specifically implemented through step 2002a described below.

[0175] Step 2002a: The first network-side device determines the rate adjustment information based on the first rate information according to the air interface data transmission status.

[0176] In some embodiments of this application, the rate information described above is used to indicate the air interface data transmission status of the network-side device.

[0177] For example, the above-mentioned air interface data transmission status can be divided into network congestion status and network non-congestion status.

[0178] For example, the above-mentioned non-congested network state can be further divided into excellent network air interface state and good network air interface state.

[0179] In some embodiments of this application, the first rate information mentioned above includes at least one of the following: rate information of a first network-side device, and rate information of at least one second network-side device.

[0180] In some embodiments of this application, the above-mentioned rate information includes, but is not limited to, at least one of the following: whether the rate needs to be adjusted, a second rate value, a quality of service flow identifier, a protocol data unit session identifier, the rate adjustment effective time, interface configuration, air interface congestion relief, and the terminal device querying the corresponding rate.

[0181] In some embodiments, the first network-side device receives at least one rate information, namely the aforementioned first rate information, from at least one other network-side device. At this time, if the first network-side device detects that the air interface data transmission status of the first network-side device is in a network congestion state, the first network-side device determines rate adjustment information based on its own rate information and the received at least one rate information, and then sends the rate adjustment information to the terminal device.

[0182] In some embodiments, the first network-side device receives at least one rate information, namely the aforementioned first rate information, from at least one other network-side device. In this case, if the first network-side device detects that the air interface data transmission status of the first network-side device is in a non-congested network state, the first network-side device determines rate adjustment information based on the received at least one rate information. For example, it performs speed-up processing only on the second rate value contained in the rate information, and then sends the rate adjustment information to the terminal device.

[0183] In some embodiments, the first network-side device receives at least one rate information from at least one other network-side device. In this case, if the first network-side device detects that the air interface data transmission status of the first network-side device is in a non-congested network state and the network transmission status is very good, the first network-side device may choose not to send the received rate information.

[0184] In some embodiments of this application, the terminal device determines the first rate value in the rate adjustment information based on all the second rate values ​​contained in the first rate information.

[0185] In some embodiments of this application, the first rate value is any one of the following:

[0186] The maximum value among all second rate values ​​contained in the rate information;

[0187] The minimum value among all second rate values ​​contained in the rate information;

[0188] The average of the maximum and minimum values ​​among all the second rate values ​​contained in the rate information;

[0189] The average of all second rate values ​​contained in the rate information;

[0190] The random value among all the second rate values ​​contained in the rate information.

[0191] The sum of all second rate values ​​contained in the rate information.

[0192] It should be noted that the detailed process of determining the first rate value based on the second rate value is the process on the terminal device side, and will not be elaborated here.

[0193] In this way, the terminal device can complete the rate adjustment operation simply by using the rate adjustment information sent by the first network-side device. Furthermore, since the first network-side device can negotiate and determine the rate adjustment information on its own, the terminal device's power consumption is reduced.

[0194] Step 2003: The first network-side device sends rate adjustment information to the terminal device.

[0195] In some embodiments of this application, the above-mentioned rate adjustment information includes a first rate value.

[0196] In some embodiments of this application, the above-mentioned rate adjustment information is used to instruct the terminal device to adjust the data transmission rate according to a first rate value.

[0197] In some embodiments of this application, the first network-side device may merge all rate information into a single piece of information and send it to the terminal device as rate adjustment information; or, the first network-side device may determine a new rate information based on the information contained in all rate information and send it to the terminal device as rate adjustment information.

[0198] In the transmission rate adjustment method provided in this application embodiment, the first network-side device can determine the rate adjustment information based on the received at least one rate information according to the air interface data transmission status, and send it to the terminal device. This allows the terminal device to adaptively adjust its own data transmission rate according to a rate adjustment information in a scenario where multiple network-side devices are connected, thereby reducing the resource consumption of the terminal device.

[0199] Optionally, in some embodiments of this application, the transmission rate adjustment method provided in this application embodiment further includes step 3001.

[0200] Step 3001: The first network-side device sends a congestion relief instruction to the terminal device.

[0201] In some embodiments of this application, the above-mentioned congestion relief indication information is used to indicate that the network congestion state has been relieved.

[0202] In some embodiments, the aforementioned network congestion relief indication information is used to indicate to the first network-side device that the network congestion state has been relieved.

[0203] In some embodiments, the aforementioned network congestion relief indication information is used to indicate that all network-side devices connected to the terminal device have been freed from network congestion.

[0204] In some embodiments, the aforementioned network congestion relief indication information is used to indicate to other network-side devices besides the first network-side device that the network congestion state has been relieved.

[0205] In this way, the first network-side device informs the terminal device whether the network congestion has been cleared by sending a congestion clearance indication message, so that the terminal device can adjust the data transmission rate in a timely manner when the network congestion is cleared.

[0206] Optionally, in some embodiments of this application, the transmission rate adjustment method provided in this application embodiment further includes step 4001.

[0207] Step 4001: The first network-side device receives a speed adjustment query message from the terminal device.

[0208] In some embodiments of this application, the speed regulation query message includes a third rate value.

[0209] In some embodiments of this application, the aforementioned speed adjustment query message is used to query whether the third network-side device accepts the third rate value.

[0210] For example, the above-mentioned query response message can be carried in MAC CE signaling, or it can be carried in RRC signaling, NAS signaling, physical layer signaling, etc., and this application does not impose any restrictions.

[0211] In some embodiments of this application, the first network-side device is a network-side device that has decongested.

[0212] In some embodiments of this application, the third rate value is the sum of the rate values ​​required by the terminal device for the service to be transmitted.

[0213] In some embodiments of this application, the aforementioned third rate value is determined based on the rate ratio configured for the terminal device by some or all of the third network-side devices in at least one third network-side device.

[0214] In one possible embodiment, the first network-side device forwards the speed adjustment query message to at least one second network-side device.

[0215] For example, the first network-side device may send the speed adjustment query information completely to at least one second network-side device, or it may parse the speed adjustment query information and send different information contents to different second network-side devices.

[0216] In this way, when the first network-side device receives data transmission from the terminal device at the third rate value, it promptly informs the terminal device, enabling the terminal device to adjust the data transmission rate in a timely manner, thereby ensuring the efficiency of data transmission by the terminal device.

[0217] The transmission rate adjustment method provided in this application can be executed by a transmission rate adjustment device. This application uses an example of a transmission rate adjustment device executing the transmission rate adjustment method to illustrate the transmission rate adjustment device provided in this application.

[0218] This application provides a transmission rate adjustment device. As an example, the transmission rate adjustment device can be a communication device or a component within a communication device, such as a chip. The communication device can be a terminal device, a network-side device, or a server, etc. Exemplarily, the terminal device can be, but is not limited to, the type of terminal device 11 listed above, and the network-side device can be, but is not limited to, the type of network-side device 12 listed above. This application does not impose specific limitations.

When implemented in hardware, the processing module can be implemented by a processor. For example, the processor can include a general-purpose processor, a special-purpose processor, such as a Central Processing Unit (CPU), a microprocessor, a Digital Signal Processor (DSP), an Artificial Intelligence (AI) processor, a Graphics Processing Unit (GPU), an Application Specific Integrated Circuit (ASIC), a Network Processor (NP), a Field Programmable Gate Array (FPGA), or other programmable logic devices, gate circuits, transistors, discrete hardware components, etc. The receiving and transmitting modules can be implemented by a communication interface, which can include one or more of the following: a transceiver, pins, circuits, a bus, and a radio frequency unit.
