本申请实施例涉及通信领域，尤其涉及一种确定终端设备网速上限的方法及电子设备。The embodiments of the present application relate to the field of communications, and in particular to a method for determining an upper limit of a network speed of a terminal device and an electronic device.
背景技术Background technique
随着LTE(3GPP Long Term Evolution，3GPP长期演进技术)，NR(New Radio，新无线)等无线网络技术的普及，人们对网络质量的要求也越来越高。对于终端设备来说，衡量网络质量的指标可以有多种，如网速，网络延迟，网速上限等。其中，网速上限是指基站能够分配给该终端设备的最大带宽对应的网速。With the popularization of wireless network technologies such as LTE (3GPP Long Term Evolution) and NR (New Radio), people have higher and higher requirements for network quality. For terminal devices, there are many indicators to measure network quality, such as network speed, network delay, and network speed limit. Among them, the network speed limit refers to the network speed corresponding to the maximum bandwidth that the base station can allocate to the terminal device.
上述指标中，网速和网络延迟均可以在终端设备侧确定，但网速上限是基站根据各终端设备的当前业务量，信噪环境等参数，通过带宽分配算法确定的。终端设备无法获知基站能够分配给自身的最大带宽，因而也无法确定自身的网速上限。Among the above indicators, network speed and network delay can be determined on the terminal device side, but the upper limit of network speed is determined by the base station through the bandwidth allocation algorithm based on the current business volume of each terminal device, signal-noise environment and other parameters. The terminal device cannot know the maximum bandwidth that the base station can allocate to itself, and therefore cannot determine its own upper limit of network speed.

The smaller value of the first rate upper limit and the total maximum bit rate is used as the upper limit of the uplink rate of the terminal device. Based on this scheme, a specific implementation method for calculating the upper limit of the uplink rate of the terminal device is provided.
在一种可能的设计中，根据预设的数据库中计算第一参数和第二参数对应的第一峰值速率，包括：根据信号与干扰加噪声比以及参考信号接收质量确定无线网络的资源块利用率。资源块利用率用于指示无线网络已分配的资源块数与总资源块数的比值。在资源块利用率小于第一预设阈值时，根据预设的数据库中计算第一参数和第二参数对应的第一峰值速率。基于该方案，资源块利用率小于第一预设阈值，说明无线网络中存在未分配的资源块，因此可以通过后续算法对下行速率上限进行计算。In one possible design, a first peak rate corresponding to a first parameter and a second parameter is calculated according to a preset database, including: determining a resource block utilization of a wireless network according to a signal to interference plus noise ratio and a reference signal reception quality. The resource block utilization is used to indicate the ratio of the number of resource blocks allocated to the wireless network to the total number of resource blocks. When the resource block utilization is less than a first preset threshold, a first peak rate corresponding to the first parameter and the second parameter is calculated according to a preset database. Based on this scheme, if the resource block utilization is less than the first preset threshold, it means that there are unallocated resource blocks in the wireless network, so the downlink rate upper limit can be calculated by a subsequent algorithm.
在一种可能的设计中，根据信号与干扰加噪声比以及参考信号接收质量确定无线网络的资源块利用率之后，方法还包括：在资源块利用率大于第一预设阈值时，将下行速率作为终端设备的下行速率上限。基于该方案，资源块利用率大于第一预设阈值，说明无线网络中不存在未分配的资源块，因此可以将终端设备当前的下行速率作为下行速率上限。In one possible design, after determining the resource block utilization of the wireless network according to the signal to interference plus noise ratio and the reference signal reception quality, the method further includes: when the resource block utilization is greater than a first preset threshold, using the downlink rate as the downlink rate upper limit of the terminal device. Based on this scheme, the resource block utilization is greater than the first preset threshold, indicating that there are no unallocated resource blocks in the wireless network, so the current downlink rate of the terminal device can be used as the downlink rate upper limit.
在一种可能的设计中，根据上行速率，当前发射功率，资源块数，信号与干扰加噪声比以及参考信号接收质量确定第一速率，包括：获取终端设备的上行缓冲时间。上行缓冲时间用于指示终端设备请求基站调度上行资源的时间。在上行缓冲时间小于第二预设阈值时，根据上行速率，当前发射功率，资源块数，信号与干扰加噪声比以及参考信号接收质量确定第一速率。基于该方案，上行缓冲时间小于第二预设阈值，说明当前无线网络上行信道较为畅通，可以通过后续算法对上行速率上限进行计算。In one possible design, the first rate is determined based on the uplink rate, the current transmit power, the number of resource blocks, the signal to interference plus noise ratio, and the reference signal reception quality, including: obtaining the uplink buffer time of the terminal device. The uplink buffer time is used to indicate the time when the terminal device requests the base station to schedule uplink resources. When the uplink buffer time is less than the second preset threshold, the first rate is determined based on the uplink rate, the current transmit power, the number of resource blocks, the signal to interference plus noise ratio, and the reference signal reception quality. Based on this scheme, the uplink buffer time is less than the second preset threshold, indicating that the current wireless network uplink channel is relatively smooth, and the uplink rate upper limit can be calculated by a subsequent algorithm.
在一种可能的设计中，获取终端设备的上行缓冲时间之后，方法还包括：在上行缓冲时间大于第二预设阈值时，将上行速率作为终端设备的上行速率上限。基于该方案，上行缓冲时间大于第二预设阈值，说明当前无线网络上行信道较为拥塞，因此可以将终端设备当前的上行速率作为上行速率上限。In one possible design, after obtaining the uplink buffer time of the terminal device, the method further includes: when the uplink buffer time is greater than the second preset threshold, using the uplink rate as the upper limit of the uplink rate of the terminal device. Based on this solution, if the uplink buffer time is greater than the second preset threshold, it means that the uplink channel of the current wireless network is relatively congested, so the current uplink rate of the terminal device can be used as the upper limit of the uplink rate.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way.
为了便于理解，下面对本申请实施例的应用背景予以说明。To facilitate understanding, the application background of the embodiments of the present application is described below.
基站，也称作公用移动通信基站，为无线电台站的一种形式，用于向其信号覆盖区域内的终端设备提供无线网络。具体地，基站可以通过预设的带宽分配算法，根据信号覆盖区域内终端设备的数量，各终端设备的当前业务量等参数为各终端设备分配带宽资源。其中，终端设备的当前业务量可以是指终端设备当前运行的联网应用的网络吞吐量。A base station, also known as a public mobile communication base station, is a form of radio station that is used to provide wireless networks to terminal devices within its signal coverage area. Specifically, the base station can allocate bandwidth resources to each terminal device based on the number of terminal devices within the signal coverage area, the current traffic volume of each terminal device, and other parameters through a preset bandwidth allocation algorithm. The current traffic volume of a terminal device may refer to the network throughput of the networked application currently running on the terminal device.
请参考图1，为一种基站与终端设备的连接示意图。如图1所示，基站a与终端设备b，终端设备c通信连接。Please refer to Figure 1, which is a schematic diagram of a connection between a base station and a terminal device. As shown in Figure 1, a base station a is in communication connection with terminal devices b and c.
示例性地，基站a可以根据终端设备b的当前业务量为终端设备b分配带宽，根据终端设备c的当前业务量为终端设备c分配带宽。例如，终端设备的当前业务量越大，基站分配给该终端设备的带宽也就越大。例如，终端设备b的当前业务量小于终端设备c的当前业务量，则基站a分配给终端设备b的带宽可以小于分配给终端设备c的带宽。Exemplarily, base station a may allocate bandwidth to terminal device b according to the current traffic volume of terminal device b, and allocate bandwidth to terminal device c according to the current traffic volume of terminal device c. For example, the larger the current traffic volume of the terminal device, the larger the bandwidth allocated to the terminal device by the base station. For example, if the current traffic volume of terminal device b is less than the current traffic volume of terminal device c, the bandwidth allocated to terminal device b by base station a may be less than the bandwidth allocated to terminal device c.
可以理解，在其他条件相同的情况下，基站分配给终端设备的带宽越大，该终端设备的当前网速就越快，该终端设备的网络质量也就越好。其中，上述“其它条件”可以为信噪环境等。It can be understood that, under the same other conditions, the larger the bandwidth allocated by the base station to the terminal device, the faster the current network speed of the terminal device and the better the network quality of the terminal device. The above-mentioned "other conditions" may be a signal-noise environment, etc.
需要说明的是，在本申请实施例中，信噪环境可以通过SINR(Signal toInterference plus Noise Ratio，信号与干扰加噪声比)，MCS(Modulation and CodingScheme,调制编码策略)等参数表征。SINR或MCS越大，信噪环境就越好，终端设备在相同带宽下的网速就越快。It should be noted that in the embodiment of the present application, the signal-to-noise environment can be characterized by parameters such as SINR (Signal to Interference plus Noise Ratio), MCS (Modulation and Coding Scheme, Modulation Coding Strategy). The larger the SINR or MCS, the better the signal-to-noise environment, and the faster the network speed of the terminal device under the same bandwidth.
然而在实际应用中，不同终端设备的信噪环境等参数不会完全相同，因此终端设备的当前网速并不能完全代表网络质量。下面以图1中的基站a，终端设备b，终端设备c为例进行示例性说明。However, in actual applications, parameters such as the signal-to-noise environment of different terminal devices are not exactly the same, so the current network speed of the terminal device cannot fully represent the network quality. The following is an exemplary description using base station a, terminal device b, and terminal device c in FIG1 as an example.
该示例中，终端设备b的当前业务量远小于终端设备c的当前业务量，且终端设备b的信噪环境优于终端设备c的信噪环境。In this example, the current traffic volume of terminal device b is much smaller than the current traffic volume of terminal device c, and the signal-to-noise environment of terminal device b is better than the signal-to-noise environment of terminal device c.
由于终端设备b的当前业务量远小于终端设备c的当前业务量，因此基站a分配给终端设备b的带宽要远小于基站a分配给终端设备c的带宽。由于终端设备的当前网速主要由基站分配的带宽确定，因此终端设备b的当前网速小于终端设备c的当前网速。Since the current traffic volume of terminal device b is much smaller than that of terminal device c, the bandwidth allocated by base station a to terminal device b is much smaller than that allocated by base station a to terminal device c. Since the current network speed of a terminal device is mainly determined by the bandwidth allocated by the base station, the current network speed of terminal device b is smaller than that of terminal device c.
在上述场景中，判断终端设备b的网络质量差于终端设备c的网络质量就不够准确。因为在基站a可分配的带宽资源充足的情况下，当终端设备b的当前业务量增大至与终端设备c的业务量相同时，基站a分配给终端设备b的带宽与基站a分配给终端设备c的带宽也会相同。如此由于终端设备b的信噪环境优于终端设备c的信噪环境，因此终端设备a的网速会大于终端设备c的网速。In the above scenario, it is not accurate to judge that the network quality of terminal device b is worse than that of terminal device c. Because when the bandwidth resources that can be allocated by base station a are sufficient, when the current service volume of terminal device b increases to the same as the service volume of terminal device c, the bandwidth allocated by base station a to terminal device b will be the same as the bandwidth allocated by base station a to terminal device c. In this way, since the signal-to-noise environment of terminal device b is better than that of terminal device c, the network speed of terminal device a will be greater than that of terminal device c.
也就是说，基站a能够分配给终端设备b的最大带宽对应的网速大于基站a能够分配给终端设备c的最大带宽对应的网速。因此，终端设备b的网络质量并不一定差于终端设备c。That is, the network speed corresponding to the maximum bandwidth that base station a can allocate to terminal device b is greater than the network speed corresponding to the maximum bandwidth that base station a can allocate to terminal device c. Therefore, the network quality of terminal device b is not necessarily worse than that of terminal device c.
在本申请实施例中，可以将基站分配给终端设备的最大带宽对应的网络速率称作网速上限。可以看出，网速上限也可以作为衡量网络质量的指标。In the embodiment of the present application, the network rate corresponding to the maximum bandwidth allocated by the base station to the terminal device can be referred to as the upper limit of the network speed. It can be seen that the upper limit of the network speed can also be used as an indicator to measure the network quality.
然而，不同于网速，时延等参数可以在终端设备侧直接测得，网速上限无法直接测量。并且，终端设备侧也无法获知基站侧的带宽分配算法，因此也无法确定自身的网速上限。However, unlike network speed, latency and other parameters that can be directly measured on the terminal device side, the upper limit of network speed cannot be directly measured. In addition, the terminal device side cannot know the bandwidth allocation algorithm on the base station side, so it cannot determine its own upper limit of network speed.
为了解决上述问题，本申请实施例提供了一种确定终端设备网速上限的方法及电子设备，可以使终端设备能够较为准确地预估自身的网速上限，从而为评估网络质量提供依据。In order to solve the above problems, the embodiments of the present application provide a method and electronic device for determining the upper limit of the network speed of a terminal device, which can enable the terminal device to more accurately estimate its own upper limit of the network speed, thereby providing a basis for evaluating network quality.

以上通过图2介绍了本申请实施例提供的终端设备的硬件结构，下面示例性说明本申请实施例提供的终端设备的软件架构。需要说明的是，在本申请实施例中终端设备也可以称作电子设备，本申请对两者并不做区分。The hardware structure of the terminal device provided in the embodiment of the present application is introduced above through Figure 2. The software architecture of the terminal device provided in the embodiment of the present application is exemplarily described below. It should be noted that in the embodiment of the present application, the terminal device can also be called an electronic device, and the present application does not distinguish between the two.
下面首先介绍本申请实施例提供的终端设备支持NR时，该终端设备的软件架构。The following first introduces the software architecture of the terminal device provided in an embodiment of the present application when the terminal device supports NR.
请参考图3，为本申请实施例提供的一种终端设备的软件架构示意图。如图3所示，该软件架构从顶层到底层依次为SDAP(Service Data Adaption Protocol，服务数据适配协议)层，PDCP(Packet Data Convergence Protocol，分组数据汇聚协议)层，RLC(RadioLink Control，无线链路控制)层，MAC(Media Access Control，媒体介入控制)层，PHY(Physical Layer，物理)层。Please refer to Figure 3, which is a schematic diagram of the software architecture of a terminal device provided in an embodiment of the present application. As shown in Figure 3, the software architecture is, from top to bottom, SDAP (Service Data Adaption Protocol) layer, PDCP (Packet Data Convergence Protocol) layer, RLC (Radio Link Control) layer, MAC (Media Access Control) layer, and PHY (Physical Layer) layer.
其中，SDAP层用于负责QoS(Quality of Service，业务服务质量)流和DRB(DataRadio Bearer，数据无线电承载)的映射关系。PDCP层负责完整性保护，加解密，重排序等；RLC层负责针对上行，根据上行调度准许(UL Grant)拆包，或针对下行，将接收到的分片包组成完整包，即组包。MAC层负责逻辑信道(协议层)和传输信道(物理层)映射，上行发包时按照逻辑信道优先级以TB为单位将MAC subPDU(Protocol Data Unit,协议数据单元)组成MAC PDU提交到物理层，下行解复用接收的数据包，根据逻辑信道序号，把对应数据包分发给映射的逻辑信道。Among them, the SDAP layer is responsible for the mapping relationship between QoS (Quality of Service) flow and DRB (Data Radio Bearer). The PDCP layer is responsible for integrity protection, encryption and decryption, reordering, etc.; the RLC layer is responsible for unpacking according to the uplink scheduling grant (UL Grant) for the uplink, or for assembling the received fragmented packets into complete packets for the downlink. The MAC layer is responsible for mapping the logical channel (protocol layer) and the transport channel (physical layer). When sending packets uplink, the MAC subPDU (Protocol Data Unit) is composed of MAC PDUs in TB units according to the logical channel priority and submitted to the physical layer. The received data packets are demultiplexed in the downlink, and the corresponding data packets are distributed to the mapped logical channels according to the logical channel sequence numbers.
在本申请实施例中，上行信号均会依次经过PDCP层，RLC层，MAC层后到达PHY层，经射频前端以及天线完成发射。下行信号经天线和射频前端接收后，会依次经过PHY层，MAC层，RLC层以及PDCP层后完成接收。因此，后续实施例中提及获取上行网络速率时，可以是指从PDCP层，RLC层，MAC层或PHY层获取。后续实施例中提及获取下行网络速率时，也可以是指从PDCP层，RLC层，MAC层或PHY层获取。后续对此不再赘述。In the embodiments of the present application, the uplink signals will pass through the PDCP layer, RLC layer, and MAC layer in sequence before reaching the PHY layer, and will be transmitted through the RF front end and the antenna. After the downlink signals are received by the antenna and the RF front end, they will pass through the PHY layer, MAC layer, RLC layer, and PDCP layer in sequence before being received. Therefore, when the uplink network rate is obtained in the subsequent embodiments, it may refer to obtaining it from the PDCP layer, RLC layer, MAC layer, or PHY layer. When the downlink network rate is obtained in the subsequent embodiments, it may refer to obtaining it from the PDCP layer, RLC layer, MAC layer, or PHY layer. This will not be described in detail later.
以上介绍了本申请实施例提供的终端设备支持NR时，该终端设备的软件架构。需要说明的是，在本申请实施例提供的终端设备支持LTE时，该终端设备的软件架构与上述图3相比仅没有SDAP层，其它均相同，此处不做赘述。The above describes the software architecture of the terminal device provided in the embodiment of the present application when the terminal device supports NR. It should be noted that when the terminal device provided in the embodiment of the present application supports LTE, the software architecture of the terminal device is the same as that of FIG. 3 above except that the SDAP layer is missing, and the rest are the same, which will not be described here.

It should be noted that the method can be executed by a module with data processing function in the terminal device, such as a processor.
需要说明的是，本申请实施例提供的确定终端设备网速上限的方法，用于确定终端设备的网速上限，即基站能够分配给终端设备的最大带宽对应的网速。可以理解，对终端设备而言，网速包括上行速率和下行速率。其中，上行速率用于指示终端设备向基站发送信号的速率。下行速率用于指示终端设备接收基站发送的信号的速率。下面首先介绍本申请实施例提供的确定终端设备网速上限的方法中，确定终端设备下行速率上限的过程。It should be noted that the method for determining the upper limit of the network speed of a terminal device provided in an embodiment of the present application is used to determine the upper limit of the network speed of the terminal device, that is, the network speed corresponding to the maximum bandwidth that the base station can allocate to the terminal device. It can be understood that for a terminal device, the network speed includes an uplink rate and a downlink rate. Among them, the uplink rate is used to indicate the rate at which the terminal device sends a signal to the base station. The downlink rate is used to indicate the rate at which the terminal device receives a signal sent by the base station. The following first introduces the process of determining the upper limit of the downlink rate of a terminal device in the method for determining the upper limit of the network speed of a terminal device provided in an embodiment of the present application.
请参考图4，为本申请实施例提供的一种确定终端设备下行速率上限的方法流程图。如图4所示，该方法包括如下步骤。Please refer to Figure 4, which is a flow chart of a method for determining the upper limit of the downlink rate of a terminal device provided in an embodiment of the present application. As shown in Figure 4, the method includes the following steps.
S401、获取终端设备的下行速率，MIMO阶数，以及当前无线网络的频段，参考信号接收质量，资源块数，信号与干扰加噪声比。S401. Obtain a downlink rate of a terminal device, a MIMO order, a frequency band of a current wireless network, a reference signal reception quality, a number of resource blocks, and a signal to interference plus noise ratio.
在本申请实施例中，终端设备的下行速率，MIMO阶数也可以称作终端设备的第一参数。当前无线网络的频段，参考信号接收质量，资源块数，信号与干扰加噪声比也可以称作无线网络的第二参数。In the embodiment of the present application, the downlink rate and MIMO order of the terminal device can also be referred to as the first parameters of the terminal device. The frequency band of the current wireless network, the reference signal reception quality, the number of resource blocks, and the signal to interference plus noise ratio can also be referred to as the second parameters of the wireless network.
终端设备的下行速率是指终端设备下行的网络速率。如上所述，该下行速率可以从终端设备的PDCP层，RLC层，MAC层或PHY层中获取，此处不再做赘述。The downlink rate of the terminal device refers to the network rate of the terminal device downlink. As mentioned above, the downlink rate can be obtained from the PDCP layer, RLC layer, MAC layer or PHY layer of the terminal device, which will not be described here.
MIMO(Multiple-In Multiple-Out,多输入多输出)阶数是指终端设备中处于工作状态的MIMO天线数量。终端设备可以从自身的配置信息中获取MIMO阶数。The MIMO (Multiple-In Multiple-Out) order refers to the number of MIMO antennas in operation in a terminal device. The terminal device can obtain the MIMO order from its own configuration information.
无线网络的频段是指LTE频段或NR频段。其中LTE频段可以包括B1，B3等，NR频段可以包括N40，N41等，此处不做赘述。The frequency band of the wireless network refers to the LTE frequency band or the NR frequency band. The LTE frequency band may include B1, B3, etc., and the NR frequency band may include N40, N41, etc., which will not be described here.
无线网络的参考信号接收质量(Reference Signal Receiving Quality，RSRQ)用于指示当前信道质量的信噪比和干扰水平。RSRQ的值越大，说明接收信号的质量越好。RSRQ的值越小，说明接收信号的质量越差。The Reference Signal Receiving Quality (RSRQ) of a wireless network is used to indicate the signal-to-noise ratio and interference level of the current channel quality. The larger the RSRQ value, the better the quality of the received signal. The smaller the RSRQ value, the worse the quality of the received signal.
根据3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)对RSRQ的定义，可以得到如下公式(1)：According to the definition of RSRQ by 3GPP (3rd Generation Partnership Project), the following formula (1) can be obtained:
其中，RSRP是参考信号接收功率(Reference Signal Receiving Power)，用于指示无线信号的强度。RSSI是接收信号强度指示(Received Signal Strength Indicator)，用于指示当前信道的接收信号强度和干扰程度。RSRP is the Reference Signal Receiving Power, which is used to indicate the strength of the wireless signal. RSSI is the Received Signal Strength Indicator, which is used to indicate the received signal strength and interference level of the current channel.
根据3GPP上对RSSI的定义，可以得到如下公式(2)：According to the definition of RSSI in 3GPP, the following formula (2) can be obtained:
RSSI＝2×N×RSRP+10×RSRP×Ratio×N+12×S×N公式(2)。RSSI=2×N×RSRP+10×RSRP×Ratio×N+12×S×N Formula (2).
其中，N为当前小区无线网络频段的实际带宽对应的总资源块数。Ratio为当前无线网络的资源块利用率。S为干扰和噪声。Wherein, N is the total number of resource blocks corresponding to the actual bandwidth of the wireless network frequency band of the current cell. Ratio is the resource block utilization rate of the current wireless network. S is interference and noise.
资源块数即RB(Resource Block)数。RB用于度量频域资源和时域资源的多少。具体地，1个RB在频域上可以包括连续12个子载波，在时域上可以包括一个时隙(slot)。其中子载波的带宽为15KHz，一个slot可以为0.5ms或0.125ms。也就是说，一个RB可以包括180Khz的频域资源和1个slot的时域资源。The number of resource blocks is the number of RBs (Resource Blocks). RBs are used to measure the number of frequency domain resources and time domain resources. Specifically, one RB can include 12 consecutive subcarriers in the frequency domain and one time slot in the time domain. The bandwidth of the subcarrier is 15KHz, and one slot can be 0.5ms or 0.125ms. In other words, one RB can include 180Khz of frequency domain resources and one slot of time domain resources.
需要说明的是，不同的RB虽然包括相同大小的频域资源和时域资源，但携带的数据量不一定相同。例如，信噪环境会影响RB携带的数据量。信噪环境越好，1个RB携带的数据量就越大。信噪环境越差，一个RB携带的数据量就越小。可以理解，在基站给两个终端设备分配同样数量的RB时，信噪环境越好的终端设备拥有更快的网速，即更好的网络质量。It should be noted that although different RBs include the same size of frequency domain resources and time domain resources, the amount of data they carry is not necessarily the same. For example, the signal-noise environment will affect the amount of data carried by the RB. The better the signal-noise environment, the greater the amount of data carried by one RB. The worse the signal-noise environment, the smaller the amount of data carried by one RB. It can be understood that when the base station allocates the same number of RBs to two terminal devices, the terminal device with a better signal-noise environment has a faster network speed, that is, better network quality.
在本申请实施例中，当前无线网络的资源块数是指当前小区无线网络频段的实际带宽对应的总RB数。例如，当前小区无线网络频段的实际带宽为LTE的20M带宽，则对应的总RB数为100个。又例如，当前小区无线网络频段的实际带宽为NR的100M带宽，则对应的总RB数为273个。In the embodiment of the present application, the number of resource blocks of the current wireless network refers to the total number of RBs corresponding to the actual bandwidth of the wireless network frequency band of the current cell. For example, if the actual bandwidth of the wireless network frequency band of the current cell is the 20M bandwidth of LTE, the corresponding total number of RBs is 100. For another example, if the actual bandwidth of the wireless network frequency band of the current cell is the 100M bandwidth of NR, the corresponding total number of RBs is 273.
信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)是指接收到的有用信号的强度与接收到的干扰信号(噪声和干扰)的强度的比值。可以简单理解为信噪比。Signal to Interference plus Noise Ratio (SINR) refers to the ratio of the strength of the received useful signal to the strength of the received interference signal (noise and interference). It can be simply understood as the signal-to-noise ratio.
根据3GPP上对SINR的定义，可以得到如下公式(3)：According to the definition of SINR in 3GPP, the following formula (3) can be obtained:
在本申请实施例中，终端设备可以在与基站进行SRS(Sounding ReferenceSignal，信道探测参考信号)的过程中获取当前无线网络的RSSI，RSRP，资源块数以及信号与干扰噪声比等参数。In an embodiment of the present application, the terminal device can obtain parameters such as RSSI, RSRP, number of resource blocks, and signal to interference and noise ratio of the current wireless network during the SRS (Sounding Reference Signal) process with the base station.
需要说明的是，上述公式(1)至公式(3)所指示的是LTE无线网络中各参数之间的关系。对于NR无线网络来说，部分参数的定义略有不同，具体可参见IEEE(Institute ofElectrical and Electronics Engineers,电气和电子工程师协会)对NR无线网络中各参数的定义，此处不做赘述。It should be noted that the above formulas (1) to (3) indicate the relationship between the parameters in the LTE wireless network. For the NR wireless network, the definitions of some parameters are slightly different. For details, please refer to the definition of the parameters in the NR wireless network by IEEE (Institute of Electrical and Electronics Engineers), which will not be repeated here.
S402、根据参考信号接收质量，信号与干扰加噪声比确定当前无线网络的资源块利用率。S402: Determine resource block utilization of the current wireless network according to a reference signal reception quality and a signal to interference plus noise ratio.
针对LTE无线网络，基于以上公式(1)至公式(3)可以推导得到如下公式(4)：For LTE wireless networks, the following formula (4) can be derived based on the above formulas (1) to (3):
针对NR无线网络，基于IEEE对各参数的定义可以推导得到如下公式(5)：For NR wireless networks, based on the IEEE definition of each parameter, the following formula (5) can be derived:
可以看出，无论是LTE无线网络还是NR无线网络，均可以根据对应无线网络的RSRQ和SINR得到该无线网络的资源块利用率Ratio。It can be seen that whether it is an LTE wireless network or an NR wireless network, the resource block utilization Ratio of the wireless network can be obtained according to the RSRQ and SINR of the corresponding wireless network.
S403、判断资源块利用率是否大于或等于100％。若否，执行S404a；若是，执行S404b。S403: Determine whether the resource block utilization rate is greater than or equal to 100%. If not, execute S404a; if so, execute S404b.
在本申请实施例中，100％可以为第一预设阈值的一种可能的数值。In the embodiment of the present application, 100% may be a possible value of the first preset threshold.
可以理解，资源块利用率大于或等于100％，说明当前空口没有可供分配的RB资源，则可以认为终端设备当前的下行速率即为下行速率上限。It can be understood that if the resource block utilization rate is greater than or equal to 100%, it means that there are no RB resources available for allocation in the current air interface, and it can be considered that the current downlink rate of the terminal device is the upper limit of the downlink rate.
而资源块利用率小于100％，说明当前空口还有可供分配的资源块。因此，通过计算该可供分配的资源块所能提供的下行速率，并与终端设备当前的下行速率相加，即可得到终端设备的下行速率上限。If the resource block utilization rate is less than 100%, it means that there are resource blocks available for allocation in the current air interface. Therefore, by calculating the downlink rate that the resource blocks available for allocation can provide and adding it to the current downlink rate of the terminal device, the downlink rate upper limit of the terminal device can be obtained.
下面先介绍资源块利用率小于100％，即当前空口存在可供分配的资源块的情况。The following first introduces the situation where the resource block utilization rate is less than 100%, that is, there are resource blocks available for allocation in the current air interface.
S404a、根据当前无线网络的频段，信号与干扰加噪声比，资源块数以及终端设备的MIMO阶数，在预设的数据库中确定终端设备的第一峰值速率。S404a: Determine a first peak rate of the terminal device in a preset database according to a frequency band of the current wireless network, a signal to interference plus noise ratio, a number of resource blocks, and a MIMO order of the terminal device.
其中，预设的数据库包括各无线网络的频段，信号与干扰加噪声比，资源块数以及MIMO阶数与峰值下行速率的对应关系。The preset database includes the frequency band of each wireless network, the signal to interference plus noise ratio, the number of resource blocks, and the correspondence between the MIMO order and the peak downlink rate.
参见上述对资源块的介绍，信噪环境，资源块数，终端设备的MIMO阶数等参数均会影响RB携带的数据量，进而影响终端设备的网络下行速率。Referring to the above introduction to resource blocks, parameters such as the signal-to-noise environment, the number of resource blocks, and the MIMO order of the terminal device will affect the amount of data carried by the RB, thereby affecting the network downlink rate of the terminal device.
在本申请实施例中，可以通过离线测试终端设备在不同的频段中，各SINR，MIMO阶数以及RB数对应的峰值下行速率，并将离线测试的结果数据存储，作为预设的数据库。可以理解，预设的数据库用于指示各频段信号中不同信噪比，资源块数以及MIMO阶数与峰值下行速率的对应关系。In the embodiment of the present application, the peak downlink rate corresponding to each SINR, MIMO order and RB number of the terminal device in different frequency bands can be tested offline, and the result data of the offline test can be stored as a preset database. It can be understood that the preset database is used to indicate the corresponding relationship between different signal-to-noise ratios, resource block numbers and MIMO orders in each frequency band signal and the peak downlink rate.
其中，预设的数据库可以如下表1所示。The preset database may be as shown in Table 1 below.
表1Table 1
如表1所示，预设的数据库中可以包括频段，SINR，RB数，MIMO阶数以及峰值速率。下面举例说明S404a的具体过程。As shown in Table 1, the preset database may include frequency band, SINR, number of RBs, MIMO order and peak rate. The specific process of S404a is described below by example.
例如，S401中获取得到的终端设备MIMO阶数为2,当前无线网络的频段为n41，资源块数为273，信号与干扰加噪声比为1。则在S404a中，根据上述表1可以确定上述参数对应的峰值速率为100Mbps。也就是说，根据上述参数可以确定终端设备的第一峰值速率为100Mbps。For example, the MIMO order of the terminal device obtained in S401 is 2, the frequency band of the current wireless network is n41, the number of resource blocks is 273, and the signal to interference plus noise ratio is 1. Then in S404a, according to the above Table 1, it can be determined that the peak rate corresponding to the above parameters is 100 Mbps. In other words, according to the above parameters, it can be determined that the first peak rate of the terminal device is 100 Mbps.
在另一些实施例中，预设的数据库中可能没有与S401中获取到的参数完全对应的峰值速率，此种情况下可以根据S401获取到的SINR在预设的数据库中确定对应的RB数以及MIMO阶数，并根据该对应的RB数以及MIMO阶数对峰值速率进行折算。In other embodiments, there may be no peak rate in the preset database that completely corresponds to the parameters obtained in S401. In this case, the corresponding number of RBs and MIMO order can be determined in the preset database based on the SINR obtained in S401, and the peak rate can be converted based on the corresponding number of RBs and MIMO order.
例如，可以通过下述公式(6)得到第一峰值速率。For example, the first peak rate can be obtained by the following formula (6).
其中，Ratecurr_peak为第一峰值速率，Rankcurr是指获取到的终端设备的MIMO阶数，Rankpeak是指预设的数据库中终端设备的MIMO阶数，RBcurr是指获取到的当前无线网络的资源块数，RBpeak是指预设的数据库中的资源块数，Ratepeak是指预设数据库中的峰值速率。Among them, Ratecurr_peak is the first peak rate, Rankcurr refers to the MIMO order of the terminal device obtained, Rankpeak refers to the MIMO order of the terminal device in the preset database, RBcurr refers to the number of resource blocks of the current wireless network obtained, RBpeak refers to the number of resource blocks in the preset database, and Ratepeak refers to the peak rate in the preset database.
示例性地，S401中获取得到的终端设备的MIMO阶数为1，当前无线网络的频段为n41，资源块数为100，信号与干扰加噪声比为1。则根据上述参数以及表1可以确定，Rankcurr为1，Rankpeak为2，RBcurr为100，RBpeak为273，Ratepeak为100Mbps。因此，根据上述公式(6)可以确定第一峰值速率为18.3Mbps。Exemplarily, the MIMO order of the terminal device obtained in S401 is 1, the frequency band of the current wireless network is n41, the number of resource blocks is 100, and the signal to interference plus noise ratio is 1. According to the above parameters and Table 1, it can be determined that Rankcurr is 1, Rankpeak is 2, RBcurr is 100, RBpeak is 273, and Ratepeak is 100Mbps. Therefore, according to the above formula (6), it can be determined that the first peak rate is 18.3Mbps.
需要说明的是，通过公式(6)计算得到的第一峰值速率没有考虑终端设备当前的下行速率，也没有考虑基站侧剩余的RB是否能够全部分配给自身，因此该第一峰值速率不能完全代表终端设备实际的下行速率上限。It should be noted that the first peak rate calculated by formula (6) does not take into account the current downlink rate of the terminal device, nor does it take into account whether all the remaining RBs on the base station side can be allocated to itself. Therefore, the first peak rate cannot fully represent the actual downlink rate upper limit of the terminal device.
S405a、根据终端设备的下行速率，第一峰值速率以及当前无线网络的资源块利用率确定终端设备的第一下行速率上限。S405a. Determine a first downlink rate upper limit of the terminal device according to the downlink rate of the terminal device, the first peak rate, and resource block utilization of the current wireless network.
具体地，可以通过下述公式(7)确定终端设备的的第一下行速率上限。Specifically, the first downlink rate upper limit of the terminal device can be determined by the following formula (7).
Rate_dl＝λ×(1-Ratio)×Ratecurr_peak+Ratecurr公式(7)。Rate_dl=λ×(1-Ratio)×Ratecurr_peak +Ratecurr Formula (7).
其中，λ为预设系数，取值范围在0到1之间，且不包括0和1。Rate_dl即为终端设备的第一下行速率上限。将公式(4)或公式(5)中计算得到的Ratio，公式(6)中计算得到Ratecurr_peak以及S401中获取到的终端设备的下行速率代入上述公式(7)，即可计算得到终端设备的第一下行速率上限。Wherein, λ is a preset coefficient, and its value range is between 0 and 1, excluding 0 and 1. Rate_dl is the first downlink rate upper limit of the terminal device. Substituting the Ratio calculated in formula (4) or formula (5), the Ratecurr_peak calculated in formula (6), and the downlink rate of the terminal device obtained in S401 into the above formula (7), the first downlink rate upper limit of the terminal device can be calculated.
之所以引入预设系数，是因为无线网络剩余的空口资源不一定能全部分配给终端设备自身，因此将剩余的空口资源对应的速率与预设系数相乘，以使计算结果能够更加准确地反映基站能够分配给终端设备自身的带宽对应的速率。The preset coefficient is introduced because the remaining air interface resources of the wireless network may not all be allocated to the terminal device itself. Therefore, the rate corresponding to the remaining air interface resources is multiplied by the preset coefficient so that the calculation result can more accurately reflect the rate corresponding to the bandwidth that the base station can allocate to the terminal device itself.
需要说明的是，在本申请实施例中，通过上述S405a得到的终端设备的第一下行速率上限还可以与终端设备的AMBR(Aggregate Maximum Bit Rate，总计最大比特率)比较，将两者的较小值作为最终确定的终端设备的下行速率上限。即下述S406a。It should be noted that, in the embodiment of the present application, the first downlink rate upper limit of the terminal device obtained by the above S405a can also be compared with the AMBR (Aggregate Maximum Bit Rate) of the terminal device, and the smaller value of the two is used as the final downlink rate upper limit of the terminal device, that is, the following S406a.
S406a、将终端设备的第一下行速率上限与终端设备的总计最大比特率中的较小值作为终端设备的下行速率上限。S406a. The smaller value between the first downlink rate upper limit of the terminal device and the total maximum bit rate of the terminal device is used as the downlink rate upper limit of the terminal device.
其中，AMBR可以理解为核心网侧对终端设备进行开户时设置的速率上限，基站向终端设备分配空口资源通常不会超过该速率上限。因此，在计算出的第一下行速率上限大于AMBR时，将AMBR作为终端设备实际的下行速率上限，准确性更高。AMBR can be understood as the upper limit of the rate set by the core network side when opening an account for the terminal device. The air interface resources allocated by the base station to the terminal device usually do not exceed this upper limit of the rate. Therefore, when the calculated first downlink rate upper limit is greater than AMBR, AMBR is used as the actual downlink rate upper limit of the terminal device, which is more accurate.
下面介绍资源块利用率大于或等于100％，即当前空口不存在可供分配的资源块的情况。The following describes a situation where the resource block utilization rate is greater than or equal to 100%, that is, there is no resource block available for allocation at the current air interface.
S404b、根据终端设备的下行速率确定终端设备的下行速率上限。S404b. Determine the upper limit of the downlink rate of the terminal device according to the downlink rate of the terminal device.
此种情况下，基站没有更多的RB分配给终端设备，因此终端设备的下行速率即下行速率上限。In this case, the base station has no more RBs to allocate to the terminal device, so the downlink rate of the terminal device is the downlink rate upper limit.
以上通过图4介绍了终端设备下行速率上限的确定方法。下面对终端设备上行速率上限的确定方法进行说明。The above describes a method for determining the upper limit of the downlink rate of a terminal device through Figure 4. The following describes a method for determining the upper limit of the uplink rate of a terminal device.
请参考图5，为本申请实施例提供的一种确定终端设备上行速率上限的方法流程图。如图5所示，该方法包括以下步骤。Please refer to Figure 5, which is a flow chart of a method for determining an upper limit of an uplink rate of a terminal device provided in an embodiment of the present application. As shown in Figure 5, the method includes the following steps.
S501、获取终端设备的上行缓冲时间，最大发射功率，当前发射功率，上行速率，分得的资源块数以及当前无线网络的参考信号接收质量，资源块数，信号与干扰加噪声比。S501. Obtain the uplink buffer time, maximum transmit power, current transmit power, uplink rate, number of allocated resource blocks, and reference signal reception quality, number of resource blocks, and signal to interference plus noise ratio of the current wireless network of the terminal device.
其中，终端设备的上行速率，最大发射功率，当前发射功率，总计最大比特率，分得的资源块数也可以称作终端设备的第三参数。无线网络的资源块数，信号与干扰加噪声比，参考信号接收质量也可以称作无线网络的第四参数。Among them, the uplink rate, maximum transmit power, current transmit power, total maximum bit rate, and number of allocated resource blocks of the terminal device can also be called the third parameter of the terminal device. The number of resource blocks of the wireless network, signal to interference plus noise ratio, and reference signal reception quality can also be called the fourth parameter of the wireless network.
上行缓冲时间是终端设备侧待发数据报文等待基站调度的时间，即终端设备请求基站调度资源的时间，可以用于评估当前上行资源的拥塞度。请参考图6，为本申请实施例提供的一种终端设备请求基站调度资源的流程图。如图6所示，该过程包括如下步骤。The uplink buffer time is the time that the data message to be sent by the terminal device side waits for the base station to schedule, that is, the time that the terminal device requests the base station to schedule resources, which can be used to evaluate the congestion of the current uplink resources. Please refer to Figure 6, which is a flowchart of a terminal device requesting a base station to schedule resources provided in an embodiment of the present application. As shown in Figure 6, the process includes the following steps.
S601、终端设备在第一时刻向基站发送授权请求。S601. The terminal device sends an authorization request to the base station at the first moment.
其中，授权请求用于请求基站指示何时能够上发数据报文。The authorization request is used to request the base station to indicate when the data message can be sent.
S602、基站在第二时刻接收到授权请求后，在第三时刻向终端设备下发调度资源。S602. After receiving the authorization request at the second moment, the base station sends scheduling resources to the terminal device at the third moment.
基站下发的调度资源用于指示终端设备在第五时刻发送数据报文。The scheduling resources sent by the base station are used to instruct the terminal device to send a data message at the fifth moment.
S603、终端设备在第四时刻收到基站下发的调度资源后，在第五时刻开始发送数据报文。S603. After receiving the scheduling resources sent by the base station at the fourth moment, the terminal device starts sending data messages at the fifth moment.
在上述终端设备请求基站调度资源的过程中，将第一时刻写作t1，第五时刻写作t5，则上行缓冲时间为t5-t1。In the process of the terminal device requesting the base station to schedule resources, the first moment is written as t1, the fifth moment is written as t5, and the uplink buffer time is t5-t1.
对于终端设备来说，其最大发射功率通常是一定的。示例性地，终端设备的天线传导功率可以为PC2(Power Class 2，功率等级2)，即26dBm，也可以为PC3(Power Class 3，功率等级3)，即23dBm。其中，dBm(decibel relative to one milliwatt，分贝毫瓦)是一种功率单位，用于指示功率的绝对值。分贝毫瓦与毫瓦的的换算可以通过下述公式(8)实现。For a terminal device, its maximum transmission power is usually certain. For example, the antenna conduction power of the terminal device can be PC2 (Power Class 2), i.e. 26dBm, or PC3 (Power Class 3), i.e. 23dBm. Among them, dBm (decibel relative to one milliwatt) is a power unit used to indicate the absolute value of power. The conversion between decibel milliwatt and milliwatt can be achieved by the following formula (8).
P＝(1mW)×10(x/10)公式(8)。P = (1 mW) × 10(x/10) formula (8).
其中，P为毫瓦，x为分贝毫瓦。Where P is milliwatt and x is decibel milliwatt.
S502、判断终端设备的上行缓冲时间是否大于预设阈值。若否，执行S503a。若是，执行S503b。S502: Determine whether the uplink buffering time of the terminal device is greater than a preset threshold. If not, execute S503a. If yes, execute S503b.
在本申请实施例中，预设阈值可以为50ms，60ms等，在此不做具体限定。In the embodiment of the present application, the preset threshold may be 50ms, 60ms, etc., which is not specifically limited here.
终端设备的上行缓冲时间大于预设阈值，说明当前网络已经比较拥塞，因此终端设备当前的上行速率即为上行速率上限。If the uplink buffer time of the terminal device is greater than the preset threshold, it means that the current network is already congested. Therefore, the current uplink rate of the terminal device is the upper limit of the uplink rate.
而终端设备的上行缓冲时间小于预设阈值，说明当前网络仍有余量，因此可以进一步确定上行速率上限。If the uplink buffer time of the terminal device is less than the preset threshold, it means that the current network still has margin, so the upper limit of the uplink rate can be further determined.
下面首先对终端设备的上行缓冲时间小于预设阈值的情况进行说明。The following first describes the situation where the uplink buffering time of the terminal device is less than a preset threshold.
S503a、根据当前无线网络的参考信号接收质量，信号与干扰加噪声比确定当前无线网络的资源块利用率。S503a: Determine resource block utilization of the current wireless network according to the reference signal reception quality and signal to interference plus noise ratio of the current wireless network.
具体的计算过程可以参见前述公式(4)和公式(5)，此处不做赘述。The specific calculation process can be found in the above formula (4) and formula (5), which will not be described in detail here.
S504a、根据终端设备的上行速率，终端设备的当前发射功率以及终端设备分得的资源块数确定第一速率。S504a. Determine a first rate according to an uplink rate of the terminal device, a current transmit power of the terminal device, and the number of resource blocks allocated to the terminal device.
第一速率用于指示每功率单位以及每个资源块对上行速率的贡献。The first rate is used to indicate the contribution of each power unit and each resource block to the uplink rate.
在本申请实施例中，确定第一速率的过程可以包括多个步骤，下面示例性说明。In an embodiment of the present application, the process of determining the first rate may include multiple steps, which are exemplarily described below.
首先，根据终端设备的上行速率，当前发射功率以及终端设备分得的资源块数计算第一速率。First, a first rate is calculated according to the uplink rate of the terminal device, the current transmission power and the number of resource blocks allocated to the terminal device.
将终端设备的上行速率称作Rateup_curr，当前发射功率称作Poweractual，终端设备分得的资源块数称作CountRB_UE。则可以通过如下公式(9)计算第一速率RateperPower_RB。The uplink rate of the terminal device is called Rateup_curr , the current transmit power is called Poweractual , and the number of resource blocks allocated to the terminal device is called CountRB_UE . The first rate RateperPower_RB can be calculated by the following formula (9).
第一速率用于指示每功率单位以及每个资源块对上行速率的贡献。因此，可以将功率余量以及资源块余量与第一速率相乘，从而得到上行速率的余量，进而得到终端设备的理论上行速率上限，即下述S505a。The first rate is used to indicate the contribution of each power unit and each resource block to the uplink rate. Therefore, the power margin and the resource block margin can be multiplied by the first rate to obtain the uplink rate margin, and then the theoretical uplink rate upper limit of the terminal device is obtained, that is, S505a below.
S505a、根据第一速率，终端设备的上行速率，最大发射功率，当前发射功率以及当前无线网络的资源块数，资源块利用率确定第一上行速率上限。S505a. Determine the first uplink rate upper limit according to the first rate, the uplink rate of the terminal device, the maximum transmit power, the current transmit power, the number of resource blocks of the current wireless network, and the resource block utilization.
在本申请实施例中，确定第一速率的过程也可以包括多个步骤，下面示例性说明。In the embodiment of the present application, the process of determining the first rate may also include multiple steps, which are exemplarily described below.
首先，根据终端设备的最大发射功率，当前发射功率计算功率余量。可以理解，功率余量即最大发射功率与当前发射功率的差值。First, the power margin is calculated based on the maximum transmit power and current transmit power of the terminal device. It can be understood that the power margin is the difference between the maximum transmit power and the current transmit power.
其次，根据当前无线网络的资源块数和资源块利用率计算资源块余量。可以理解，资源块余量即1与资源块利用率的差值与资源块数的乘积。Secondly, the resource block margin is calculated according to the number of resource blocks and resource block utilization of the current wireless network. It can be understood that the resource block margin is the product of the difference between 1 and the resource block utilization and the number of resource blocks.
其次，根据功率余量，资源块余量以及第一速率计算上行速率余量。如上所述，上行速率余量即功率余量，资源块余量以及第一速率的乘积。Secondly, the uplink rate margin is calculated according to the power margin, the resource block margin and the first rate. As mentioned above, the uplink rate margin is the product of the power margin, the resource block margin and the first rate.
最后，终端设备的上行速率与上行速率余量的和即第一上行速率上限。Finally, the sum of the uplink rate of the terminal device and the uplink rate margin is the first uplink rate upper limit.
将上行速率余量称作Ratespare，资源块利用率称作Ratio，资源块数称作CountRB_Cell,最大发射功率称作Powermax，终端设备的上行速率称作Rateup_curr，第一上行速率上限称作Rate_up，则可以根据如下公式(10)计算第一上行速率上限。The uplink rate margin is called Ratespare , the resource block utilization is called Ratio, the number of resource blocks is called CountRB_Cell , the maximum transmission power is called Powermax , the uplink rate of the terminal device is called Rateup_curr , and the first uplink rate upper limit is called Rate_up. The first uplink rate upper limit can be calculated according to the following formula (10).
Rate_up＝CountRB_Cell×(1-Ratio)×RateperPower_RB×(Powermax-Poweractual)+Rateup_curr公式(10)。Rate_up=CountRB_Cell ×(1-Ratio)×RateperPower_RB ×(Powermax −Poweractual )+Rateup_curr Formula (10).
在本申请实施例中，第一上行速率上限只是终端设备理论上的上行速率上限。在第一上行速率上限小于或等于AMBR时，可以将第一上行速率上限作为终端设备实际的上行速率上限。而在第一上行速率上限大于AMBR时，由于基站向终端设备分配空口资源通常不会超过AMBR，因此AMBR为终端设备实际的上行速率上限。In the embodiment of the present application, the first uplink rate upper limit is only the theoretical uplink rate upper limit of the terminal device. When the first uplink rate upper limit is less than or equal to the AMBR, the first uplink rate upper limit can be used as the actual uplink rate upper limit of the terminal device. When the first uplink rate upper limit is greater than the AMBR, since the air interface resources allocated by the base station to the terminal device usually do not exceed the AMBR, the AMBR is the actual uplink rate upper limit of the terminal device.
S506a、将终端设备的第一上行速率上限与终端设备的总计最大比特率中的较小值作为终端设备的上行速率上限。S506a: The smaller value of the first uplink rate upper limit of the terminal device and the total maximum bit rate of the terminal device is used as the uplink rate upper limit of the terminal device.
以上通过S503a-S506a介绍了终端设备的上行缓冲时间小于预设阈值时，确定终端设备实际上行速率上限的过程。下面对终端设备的上行缓冲时间大于或等于预设阈值时，确定终端设备实际上行速率上限的过程进行说明。The above S503a-S506a introduces the process of determining the actual upper limit of the uplink rate of the terminal device when the uplink buffer time of the terminal device is less than the preset threshold. The following describes the process of determining the actual upper limit of the uplink rate of the terminal device when the uplink buffer time of the terminal device is greater than or equal to the preset threshold.
S503b、根据终端设备的上行速率确定终端设备的上行速率上限。S503b. Determine the upper limit of the uplink rate of the terminal device according to the uplink rate of the terminal device.
终端设备的上行缓冲时间大于预设阈值，说明当前网络已经比较拥塞，因此终端设备当前的上行速率即为上行速率上限。If the uplink buffer time of the terminal device is greater than the preset threshold, it means that the current network is already congested. Therefore, the current uplink rate of the terminal device is the upper limit of the uplink rate.
基于以上说明可以看出，本申请实施例提供的确定终端设备网速上限的方法，能够在终端设备侧较为准确地计算得到基站能够分配给终端设备的最大带宽对应的网速上限，从而为衡量终端设备的网络质量提供依据。Based on the above description, it can be seen that the method for determining the upper limit of the network speed of a terminal device provided in the embodiment of the present application can more accurately calculate the upper limit of the network speed corresponding to the maximum bandwidth that the base station can allocate to the terminal device on the terminal device side, thereby providing a basis for measuring the network quality of the terminal device.
