Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a bandwidth subset BWP switching method, device, network side equipment and terminal. Background Art

[0002] In order to support flexible bandwidth configuration, the prior art proposes the concept of BWP (Bandwidth Part, bandwidth subset). Among them, configuring a large bandwidth BWP will increase the power consumption of UE (User Equipment) while ensuring the user's large business needs. Therefore, for UEs with low business rates, configuring a small bandwidth BWP can not only ensure the user's business needs, but also reduce power consumption. Because the user's business needs change in real time, the base station needs to dynamically switch the BWP according to the user's actual business needs.

[0003] The existing solution performs BWP switching based on the average uplink and downlink rates of users, which is positively correlated with the time-frequency domain resources they occupy. However, when air interface resources are limited, the average uplink and downlink rates of users cannot truly reflect the actual data volume requirements of users, which will cause the base station to misjudge the actual data volume requirements of users, causing confusion in BWP switching and affecting the user experience rate. Summary of the invention

[0004] The purpose of the present invention is to provide a bandwidth subset BWP switching method, device, network side equipment and terminal, so as to solve the problem that the BWP switching method in the prior art may cause confusion in BWP switching and affect the user experience rate.

[0005] In order to achieve the above object, an embodiment of the present invention provides a bandwidth subset BWP switching method, including:

[0006] When the first BWP of the first terminal is in an activated state, the network side device obtains the data volume corresponding to each transmission in multiple consecutive transmissions of the first terminal on the first BWP;

[0007] The network side device instructs the first terminal to switch to the second BWP according to the amount of data corresponding to each transmission in multiple consecutive transmissions by the first terminal on the first BWP;

[0008] Wherein, in the case where the bandwidth of the first BWP is less than the bandwidth of the second BWP, the amount of data corresponding to each transmission is the amount of remaining data after each transmission;

[0009] In the case where the bandwidth of the first BWP is greater than the bandwidth of the second BWP, the amount of data corresponding to each transmission is the amount of data transmitted per transmission.

[0010] The network side device instructs the first terminal to switch to the second BWP according to the amount of data corresponding to each transmission in multiple consecutive transmissions of the first terminal on the first BWP, including:

[0011] Determine the number of transmissions in which the data volume continuously meets the first threshold value according to the data volume corresponding to each transmission in multiple consecutive transmissions by the first terminal on the first BWP;

[0012] If the number of transmissions reaches a second threshold, the first terminal is instructed to switch to a second BWP.

[0013] The step of determining the number of transmissions in which the data volume continuously meets the first threshold value according to the data volume corresponding to each transmission in multiple consecutive transmissions by the first terminal on the first BWP includes:

[0014] When the bandwidth of the first BWP is less than the bandwidth of the second BWP, determining the number of transmissions in which the remaining data amount is continuously greater than zero according to the remaining data amount after each transmission in multiple consecutive transmissions by the first terminal on the first BWP;

[0015] In the case that the bandwidth of the first BWP is greater than the bandwidth of the second BWP, the number of transmissions with a consecutive zero data volume is determined according to the data volume of each transmission in multiple consecutive transmissions by the first terminal on the first BWP.

[0016] The step of determining the number of transmissions in which the data volume continuously meets the first threshold value according to the data volume corresponding to each transmission in multiple consecutive transmissions by the first terminal on the first BWP includes:

[0018] Determine, from the updated queue to be switched, the number of transmissions during which the amount of data corresponding to the first terminal continuously meets the first threshold value;

[0019] If the bandwidth of the first BWP is smaller than the bandwidth of the second BWP, the queue to be switched includes a first queue to be switched and a second queue to be switched, the amount of data corresponding to the terminal in the first queue to be switched is the amount of uplink data, and the amount of data corresponding to the terminal in the second queue to be switched is the amount of downlink data;

[0020] If the bandwidth of the first BWP is greater than the bandwidth of the second BWP, the queue to be switched is a third queue to be switched, and the data volume corresponding to the terminals in the third queue to be switched includes an uplink data volume and a downlink data volume.

[0021] The updating of the pre-established queue to be switched includes:

[0022] When the amount of data corresponding to one transmission by the first terminal on the first BWP meets the first threshold, the number of transmissions for which the amount of data corresponding to the first terminal continuously meets the first threshold is increased by 1.

[0023] Wherein, the method further comprises:

[0024] When the bandwidth of the first BWP is greater than the bandwidth of the second BWP, in the process of periodically traversing the first queue to be switched, if the first terminal has a transmission data volume, the first quantity is cleared;

[0025] When the bandwidth of the first BWP is smaller than the bandwidth of the second BWP and the amount of remaining data corresponding to the first terminal does not meet a first threshold, deleting the first terminal from the first queue to be switched;

[0026] When the bandwidth of the first BWP is greater than the bandwidth of the second BWP, if the first terminal has a certain amount of transmission data, and the number of transmissions for which the amount of data corresponding to the first terminal continuously meets the first threshold value does not reach the second threshold value, the number of transmissions for which the amount of data corresponding to the first terminal continuously meets the first threshold value is cleared.

[0090] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0091] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0092] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0093] The embodiments of the present application provide a bandwidth subset BWP switching method, apparatus, network-side equipment and terminal, which are used to solve the problem that the BWP switching method in the prior art may cause confusion in BWP switching and affect the user experience rate.

[0094] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0095] like Figure 1 FIG. 1 is a flow chart of a bandwidth subset BWP switching method provided by an embodiment of the present invention, and the method is applied to a network side device. Specifically, the method includes:

[0096] Step 101: When a first BWP of a first terminal is in an activated state, a network-side device obtains a data volume corresponding to each transmission in multiple consecutive transmissions of the first terminal on the first BWP;

[0097] It should be noted that when the first terminal accesses, the network-side device configures two BWPs with different bandwidths for it, namely, a first BWP and a second BWP.

[0098] That is, the terminal supports data transmission on two bandwidths, the first BWP and the second BWP. Here, the transmission data specifically refers to the transmission of service data.

[0099] Step 102: The network-side device instructs the first terminal to switch to the second BWP according to the amount of data corresponding to each transmission in multiple consecutive transmissions by the first terminal on the first BWP.

[0100] Wherein, in the case where the bandwidth of the first BWP is less than the bandwidth of the second BWP, the amount of data corresponding to each transmission is the amount of remaining data after each transmission;

[0101] In the case where the bandwidth of the first BWP is greater than the bandwidth of the second BWP, the amount of data corresponding to each transmission is the amount of data transmitted per transmission.

[0102] The bandwidth subset BWP switching method of the embodiment of the present invention is as follows: when the first BWP of the first terminal is in an activated state, the network side device obtains the data volume corresponding to each transmission in multiple consecutive transmissions of the first terminal on the first BWP; the network side device instructs the first terminal to switch to the second BWP according to the data volume corresponding to each transmission in multiple consecutive transmissions of the first terminal on the first BWP; wherein, when the bandwidth of the first BWP is smaller than the bandwidth of the second BWP, the data volume corresponding to each transmission is the remaining data volume after each transmission; when the bandwidth of the first BWP is larger than the bandwidth of the second BWP, the data volume corresponding to each transmission is the data volume of each transmission, so that the BWP switching is triggered by the transmission data volume of the corresponding terminal, which can more accurately reflect the user data volume demand and ensure the user rate.

[0103] As an optional implementation, in step 102 of the method of the embodiment of the present invention, the network side device instructs the first terminal to switch to the second BWP according to the amount of data corresponding to each transmission in multiple consecutive transmissions of the first terminal on the first BWP, including:

[0104] Determine the number of transmissions in which the data volume continuously meets the first threshold value according to the data volume corresponding to each transmission in multiple consecutive transmissions by the first terminal on the first BWP;

[0105] Here, the multiple consecutive transmissions by the first terminal on the first BWP include uplink data transmission and downlink data transmission.

[0106] Furthermore, this step may specifically include:

[0107] When the bandwidth of the first BWP is less than the bandwidth of the second BWP, determining the number of transmissions in which the remaining data amount is continuously greater than zero according to the remaining data amount after each transmission in multiple consecutive transmissions by the first terminal on the first BWP;

[0108] Here, in this case, that is, the first terminal is currently activated on a small bandwidth BWP, and the remaining data amount of the first terminal after one transmission on the first BWP is greater than zero, indicating that after the network side device schedules the first terminal on the transmission time slot, there is still remaining data to be transmitted, and when the number of transmissions in which the remaining data amount is continuously greater than zero reaches a second threshold value, it means that the resources scheduled by the network side device cannot meet the user data transmission requirements, and the network side device needs to instruct the first terminal to switch to the second BWP, that is, the large bandwidth BWP.

[0109] In the case that the bandwidth of the first BWP is greater than the bandwidth of the second BWP, the number of transmissions with a consecutive zero data volume is determined according to the data volume of each transmission in multiple consecutive transmissions by the first terminal on the first BWP.

[0110] Here, in this case, that is, the first terminal is currently activated on a large bandwidth BWP, and the amount of data transmitted by the first terminal at one time on the first BWP is zero, that is, there is no data to be transmitted, and the number of times the amount of data is consecutively zero reaches a second threshold value, indicating that the network side device does not need to schedule a large amount of resources. In order to save resources and reduce power consumption, the network side needs to instruct the first terminal to switch to the second BWP, that is, the small bandwidth BWP.

[0111] As an optional implementation, determining the number of transmissions in which the data amount continuously meets the first threshold value according to the data amount corresponding to each transmission in multiple consecutive transmissions by the first terminal on the first BWP includes:

[0112] According to the amount of data corresponding to each transmission in multiple consecutive transmissions of the first terminal on the first BWP, a pre-established queue to be switched is updated, wherein the queue to be switched includes: identifiers of multiple terminals; the number of transmissions in which the amount of data corresponding to each terminal respectively continuously meets a first threshold value, and the first terminal is any one of the multiple terminals;

[0113] If the bandwidth of the first BWP is smaller than the bandwidth of the second BWP, the queue to be switched includes a first queue to be switched and a second queue to be switched, the amount of data corresponding to the terminal in the first queue to be switched is the amount of uplink data, and the amount of data corresponding to the terminal in the second queue to be switched is the amount of downlink data;

[0114] If the bandwidth of the first BWP is greater than the bandwidth of the second BWP, the queue to be switched is a third queue to be switched, and the data volume corresponding to the terminals in the third queue to be switched includes an uplink data volume and a downlink data volume.

[0115] In this step, updating the pre-established queue to be switched may specifically include:

[0116] When the amount of data corresponding to one transmission by the first terminal on the first BWP meets the first threshold, the number of transmissions for which the amount of data corresponding to the first terminal continuously meets the first threshold is increased by 1.

[0117] The number of transmission times during which the amount of data corresponding to the first terminal continuously meets the first threshold value is determined from the updated queue to be switched.

[0118] If the number of transmissions reaches a second threshold, the first terminal is instructed to switch to a second BWP.

[0119] Here, the number of transmissions is the number of transmissions during which the amount of data corresponding to the first terminal continuously meets the first threshold.

[0120] It should be noted that the embodiment of the present invention can dynamically configure the switching threshold and support millisecond-level and second-level BWP switching, thereby improving the sensitivity of BWP dynamic switching.

[0121] As an optional implementation, this step may include:

[0122] The queue to be switched is periodically traversed, and when the number of transmissions of the data volume corresponding to the first terminal continuously meeting the first threshold value reaches the second threshold value, the first terminal is instructed to switch to the second BWP.

[0123] Here, for example, the queue to be switched is traversed every half frame to obtain the number of transmissions of the data volume corresponding to each terminal that continuously meets the first threshold value, and if there is a terminal that meets the above conditions, the terminal is triggered to perform BWP switching. The first terminal here generally refers to any one of the multiple terminals in the queue to be switched.

[0124] It should be noted that in order to save energy consumption, the queue to be switched can be periodically traversed to obtain the number of times the data volume corresponding to each terminal in the queue continuously meets the first threshold value; of course, the queue to be switched can also be monitored in real time to obtain the number of times the data volume corresponding to each terminal in the queue continuously meets the first threshold value.

[0125] As an optional implementation, the method in the embodiment of the present invention further includes:

[0126] When the bandwidth of the first BWP is smaller than the bandwidth of the second BWP and the amount of remaining uplink data corresponding to the first terminal does not meet a first threshold, deleting the first terminal from the first queue to be switched;

[0127] When the bandwidth of the first BWP is smaller than the bandwidth of the second BWP and the remaining downlink data amount corresponding to the first terminal does not meet the first threshold, the first terminal is deleted from the second queue to be switched;

[0128] In the above two situations, that is, the first terminal is activated on a small bandwidth BWP, at this time, the remaining data amount corresponding to the first terminal (the remaining uplink data amount or the remaining downlink data amount) does not meet the first threshold value, that is, the remaining data amount corresponding to the first terminal is equal to zero, that is, after the network side device schedules the first terminal on the transmission time slot, there is no remaining data amount, which means that the resources scheduled by the network side device can meet the user data transmission requirements and no BWP switching is required. In order to reduce the resources occupied by the first queue to be switched (corresponding to the remaining uplink data amount) or the resources occupied by the second queue to be switched (corresponding to the remaining downlink data amount), the first terminal can be deleted from the first queue to be switched or the second queue to be switched.

[0129] When the bandwidth of the first BWP is greater than the bandwidth of the second BWP, if the first terminal has a certain amount of transmission data, and the number of transmissions for which the amount of data corresponding to the first terminal continuously meets the first threshold value does not reach the second threshold value, the number of transmissions for which the amount of data corresponding to the first terminal continuously meets the first threshold value is cleared.

[0130] It should be noted that in this case, that is, the first terminal is currently activated on the large bandwidth BWP, the number of transmissions of the data volume corresponding to each terminal that continuously meets the first threshold value and whether each terminal has a transmission data volume can be known by real-time monitoring of the third queue to be switched or periodically traversing the third queue to be switched. Here, if the first terminal has transmission data, it means that the first terminal has uplink data or downlink data to transmit. This event can be understood as an interruption. The first terminal had no data transmission before and has been updating the first quantity (i.e., the cumulative number of times). It was interrupted by this event, indicating that the network-side device needs to schedule resources to send or receive data. BWP switching is not required at present. Since the number of times the data volume is continuously zero needs to reach the second threshold value to trigger switching, the first quantity corresponding to the first terminal is cleared to facilitate the subsequent accurate triggering of BWP switching.

[0131] The above implementation method is based on the number of transmissions of the data volume corresponding to the first terminal obtained in the queue to be switched that continuously meets the first threshold value, indicating that the first terminal is in the queue to be switched, then what conditions must be met to enter the queue to be switched. As an optional implementation method, when the bandwidth of the first BWP is less than the bandwidth of the second BWP, it is determined that the first condition is met and the first terminal is added to the first queue to be switched;

[0132] The first condition is one of the following:

[0133] Receiving a scheduling request SR reported by the first terminal;

[0134] Receiving a buffer status report BSR reported by the first terminal;

[0135] Here, in this case, the first terminal is activated on the small bandwidth BWP, and receiving the SR (Scheduling Request) reported by the first terminal indicates that the first terminal has uplink services to transmit and may need BWP switching, so it is added to the first queue to be switched, that is, the uplink small switch large switch queue.

[0136] Receive the BSR (Buffer State Report) reported by the first terminal. Here, BSR is used to indicate the amount of data that the terminal needs to transmit. That is to say, the first terminal has uplink data to be transmitted and may also need BWP switching, so it is added to the first queue to be switched, that is, the uplink small-to-large queue.

[0137] When the bandwidth of the first BWP is smaller than the bandwidth of the second BWP and downlink data is sent to the first terminal, adding the first terminal to the second queue to be switched;

[0138] Here, sending downlink data to the first terminal indicates that the first terminal needs to receive downlink data and may also need BWP switching, so it is added to the second queue to be switched, that is, the downlink small-to-large queue.

[0139] When the bandwidth of the first BWP is greater than the bandwidth of the second BWP, the first terminal is added to the third queue to be switched.

[0140] It should be noted that, in this case, the bandwidth of the first BWP is greater than the bandwidth of the second BWP, indicating that the first terminal is activated on a large-bandwidth BWP (whether it is initially activated on a large-bandwidth BWP or subsequently switched to a large-bandwidth BWP), and there is a possibility that BWP switching is required, so the first terminal is added to the third queue to be switched, that is, the large-to-small queue.

[0141] The implementation process of the bandwidth subset BWP switching method according to the embodiment of the present invention is specifically described below with reference to the following example.

[0142] Example 1: For a terminal currently activated on a small bandwidth BWP

[0143] a1) Maintaining the upstream small-cut large queue

[0144] When receiving the SR or BSR reported by the terminal, the terminal is added to the uplink small-to-large queue, and the number of times the terminal has remaining uplink data after uplink data transmission is initialized to 0;

[0145] When the remaining uplink data volume of a terminal in a small bandwidth transmission is greater than zero, the number of times the terminal has remaining uplink data volume after uplink data transmission is increased by 1;

[0146] It should be noted that after each uplink time slot is scheduled, the network side equipment knows the remaining uplink data volume to be scheduled for each terminal. If the scheduling resources cannot meet the user's reporting needs each time, the number of times the uplink data volume remains after the uplink data transmission of the terminal whose data has not been reported after each scheduling will be increased by 1.

[0147] When there is no remaining uplink data after the terminal is scheduled in the uplink timeslot, the terminal is deleted from the uplink small-to-large queue.

[0148] a2) Periodically determine whether the uplink small-to-large queue

[0149] When the terminal transmits multiple times in succession on a small bandwidth, and the number of times the remaining uplink data volume is continuously greater than zero reaches the uplink small switching threshold (second threshold), BWP switching is triggered.

[0150] Specifically, the uplink small-to-large queue can be traversed periodically (for example, every half frame) to obtain the number of times the remaining uplink data volume corresponding to each terminal is continuously greater than zero. When a terminal transmits multiple times on a small bandwidth continuously, and the number of times the remaining uplink data volume is continuously greater than zero reaches the uplink small-to-large threshold, BWP switching is triggered.

[0151] a3) Maintaining the downlink small-cut large queue

[0152] When a terminal receives downlink data, it is added to the downlink small-to-large queue, and the number of times the amount of downlink data remaining after the downlink data transmission of the terminal is initialized is 0;

[0153] When the remaining downlink data volume of a terminal in a small bandwidth transmission is greater than zero, the number of times the terminal has remaining data volume after downlink data transmission is increased by 1;

[0154] When there is no remaining downlink data after the terminal is scheduled in the downlink timeslot, the terminal is deleted from the downlink small-to-large queue.

[0155] a4) Periodically determine whether the downlink small-cut large queue

[0156] When the terminal transmits multiple times in succession on a small bandwidth, and the number of times the amount of remaining downlink data is continuously greater than zero reaches a downlink small switching threshold (a second threshold), a BWP switching is triggered.

[0157] Specifically, the downlink small-to-large queue can be traversed periodically (for example, every half frame) to obtain the number of times the remaining downlink data volume corresponding to each terminal is continuously greater than zero. When a terminal transmits multiple times on a small bandwidth continuously, and the number of times the remaining downlink data volume is continuously greater than zero reaches the uplink small-to-large threshold, BWP switching is triggered.

[0158] Example 2: For a terminal currently activated on a large bandwidth BWP

[0159] b1) Maintain large and small queues

[0160] When a terminal is initially activated on a large bandwidth BWP or switched to a large bandwidth BWP, the terminal is added to a large-to-small switching queue, and the number of times the terminal has no data transmission (including no downlink data transmission and no uplink data transmission) is initialized to 0;

[0161] When the amount of data transmitted at one time by a terminal on a large bandwidth is zero, the number of times the terminal has no data transmission is increased by 1.

[0162] b2) Periodically determine whether to cut large or small queues

[0163] The large-to-small queue can be traversed periodically (for example, every half frame), and the number of times a terminal has no data transmission is increased by 1. When the number of times no data transmission reaches the large-to-small threshold (the second threshold), BWP switching is triggered.

[0164] In the process of periodically traversing the downlink large-to-small queue, if the terminal needs to send uplink data or receive downlink data, the number of times no data is transmitted is cleared.

[0165] The bandwidth subset BWP switching method of the embodiment of the present invention is as follows: when the first BWP of the first terminal is in an activated state, the network side device obtains the data volume corresponding to each transmission in multiple consecutive transmissions of the first terminal on the first BWP; the network side device instructs the first terminal to switch to the second BWP according to the data volume corresponding to each transmission in multiple consecutive transmissions of the first terminal on the first BWP; wherein, when the bandwidth of the first BWP is smaller than the bandwidth of the second BWP, the data volume corresponding to each transmission is the remaining data volume after each transmission; when the bandwidth of the first BWP is larger than the bandwidth of the second BWP, the data volume corresponding to each transmission is the data volume of each transmission, so that the BWP switching is triggered by the transmission data volume of the corresponding terminal, which can more accurately reflect the user data volume demand and ensure the user rate.

[0166] like Figure 2 As shown, it is a schematic diagram of a flow chart of a bandwidth subset BWP switching method provided by an embodiment of the present invention. The method is applied to a terminal. The method may include:

[0167] Step 201: When a first BWP of a first terminal is in an activated state, the first terminal receives a BWP switching indication sent by a network side device, where the BWP switching indication is used to indicate switching to a second BWP, and the BWP switching indication is generated by the network side device based on a data amount corresponding to each transmission in a plurality of consecutive transmissions of the first terminal on the first BWP;

[0168] Step 202: The first terminal performs BWP switching according to the BWP switching indication;

[0169] Wherein, in the case where the bandwidth of the first BWP is less than the bandwidth of the second BWP, the amount of data corresponding to each transmission is the amount of remaining data after each transmission;

[0170] In the case where the bandwidth of the first BWP is greater than the bandwidth of the second BWP, the amount of data corresponding to each transmission is the amount of data transmitted per transmission.

[0171] The bandwidth subset BWP switching method of the embodiment of the present invention is as follows: when the first BWP of the first terminal is in an activated state, the first terminal receives a BWP switching indication sent by a network side device, the BWP switching indication is used to indicate switching to a second BWP, and the BWP switching indication is generated by the network side device based on the amount of data corresponding to each transmission in multiple consecutive transmissions of the first terminal on the first BWP; the first terminal performs BWP switching according to the BWP switching indication; wherein, when the bandwidth of the first BWP is less than the bandwidth of the second BWP, the amount of data corresponding to each transmission is the remaining amount of data after each transmission; when the bandwidth of the first BWP is greater than the bandwidth of the second BWP, the amount of data corresponding to each transmission is the amount of data transmitted each time, so that the BWP switching is triggered by the transmission data amount of the corresponding terminal, which can more accurately reflect the user data amount demand and ensure the user rate.

[0172] As an optional implementation, in step 202 of the method of the embodiment of the present invention, the first terminal performs BWP switching according to the BWP switching indication, including:

[0173] When the first terminal has the BWP switching delay capability and reports it to the network side device, and determines that the terminal air interface parameters remain unchanged, the BWP switching is performed through downlink control information according to the BWP switching indication.

[0178] The first terminal does not have a BWP switching delay capability;

[0179] The first terminal has a BWP switching delay capability and has not reported it to the network side device.

[0180] It should be noted that the above implementation shows that the embodiment of the present invention can dynamically select a switching mode according to a switching scenario.

[0181] The bandwidth subset BWP switching method of the embodiment of the present invention is as follows: when the first BWP of the first terminal is in an activated state, the first terminal receives a BWP switching indication sent by a network side device, the BWP switching indication is used to indicate switching to a second BWP, and the BWP switching indication is generated by the network side device based on the amount of data corresponding to each transmission in multiple consecutive transmissions of the first terminal on the first BWP; the first terminal performs BWP switching according to the BWP switching indication; wherein, when the bandwidth of the first BWP is less than the bandwidth of the second BWP, the amount of data corresponding to each transmission is the remaining amount of data after each transmission; when the bandwidth of the first BWP is greater than the bandwidth of the second BWP, the amount of data corresponding to each transmission is the amount of data transmitted each time, so that the BWP switching is triggered by the transmission data amount of the corresponding terminal, which can more accurately reflect the user data amount demand and ensure the user rate.
