Description

Method for determining upper limit of network speed of terminal equipment and electronic equipment

Technical Field

The embodiment of the application relates to the field of communication, in particular to a method for determining an upper limit of a network speed of terminal equipment and electronic equipment.

Background

With the popularization of wireless network technologies such as LTE (3GPP Long Term Evolution,3GPP long term evolution technology), NR (New Radio), and the like, the requirements of people on network quality are also increasing. For the terminal device, there may be various indexes for measuring the network quality, such as network speed, network delay, and upper limit of network speed. The upper limit of the network speed refers to the network speed corresponding to the maximum bandwidth that the base station can allocate to the terminal equipment.

In the above indexes, the network speed and the network delay can be determined at the terminal equipment side, but the upper limit of the network speed is determined by the base station according to the current traffic of each terminal equipment, the signal-to-noise environment and other parameters through a bandwidth allocation algorithm. The terminal device cannot know the maximum bandwidth that the base station can allocate to itself, and thus cannot determine the upper limit of its own network speed.

Detailed Description

The terms "first," "second," and "third," etc. in embodiments of the application are used for distinguishing between different objects and not for defining a particular sequence. Furthermore, the words "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

For ease of understanding, the following description is given of the application background of the embodiments of the present application.

A base station, also called public mobile communication base station, is a form of radio station for providing a wireless network to terminal devices within its signal coverage area. Specifically, the base station may allocate bandwidth resources to each terminal device according to parameters such as the number of terminal devices in the signal coverage area and the current traffic of each terminal device through a preset bandwidth allocation algorithm. The current traffic of the terminal device may refer to the network throughput of the networking application currently running by the terminal device.

Fig. 1 is a schematic diagram of a connection between a base station and a terminal device. As shown in fig. 1, the base station a is communicatively connected to the terminal device b and the terminal device c.

For example, the base station a may allocate bandwidth to the terminal device b according to the current traffic of the terminal device b, and allocate bandwidth to the terminal device c according to the current traffic of the terminal device c. For example, the greater the current traffic of a terminal device, the greater the bandwidth allocated to that terminal device by the base station. For example, if the current traffic volume of terminal equipment b is smaller than the current traffic volume of terminal equipment c, the bandwidth allocated to terminal equipment b by base station a may be smaller than the bandwidth allocated to terminal equipment c.

It will be appreciated that, under otherwise identical conditions, the greater the bandwidth allocated by the base station to a terminal device, the faster the current network speed of that terminal device, and the better the network quality of that terminal device. The "other conditions" may be a signal-to-noise environment or the like.

It should be noted that, in the embodiment of the present application, the signal-to-noise environment may be characterized by parameters such as SINR (Signal to Interference plus Noise Ratio, signal-to-interference-plus-noise ratio), MCS (Modulation and Coding Scheme, modulation and coding strategy), and the like. 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.

However, in practical applications, parameters such as signal-to-noise environments of different terminal devices are not completely the same, so the current network speed of the terminal device cannot completely represent the network quality. An exemplary explanation will be given below taking a base station a, a terminal device b, and a terminal device c in fig. 1 as an example.

In this example, the current traffic volume of terminal device b is much smaller than that of terminal device c, and the signal-to-noise environment of terminal device b is better than that of terminal device c.

Since the current traffic volume of terminal equipment b is much smaller than that of terminal equipment c, the bandwidth allocated to terminal equipment b by base station a is much smaller than that allocated to terminal equipment c by base station a. Since the current network speed of the terminal device is mainly determined by the bandwidth allocated by the base station, the current network speed of the terminal device b is smaller than the current network speed of the terminal device c.

In the above scenario, it is not accurate enough to judge that the network quality of the terminal device b is worse than that of the terminal device c. Since in the case where the bandwidth resources assignable by the base station a are sufficient, when the current traffic of the terminal device b is increased to be the same as that of the terminal device c, the bandwidth allocated by the base station a to the terminal device b and the bandwidth allocated by the base station a to the terminal device c will be the same. Thus, since the signal-to-noise environment of the terminal equipment b is better than that of the terminal equipment c, the network speed of the terminal equipment a is greater than that of the terminal equipment c.

That is, the network speed corresponding to the maximum bandwidth that the base station a can allocate to the terminal device b is greater than the network speed corresponding to the maximum bandwidth that the base station a can allocate to the terminal device c. Therefore, the network quality of terminal device b is not necessarily inferior to that of terminal device c.

In the embodiment of the application, the network rate corresponding to the maximum bandwidth allocated to the terminal equipment by the base station can be called 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 index for measuring the network quality.

However, different from the network speed, parameters such as time delay and the like can be directly measured at the terminal equipment side, and the upper limit of the network speed cannot be directly measured. In addition, the terminal equipment side cannot learn the bandwidth allocation algorithm of the base station side, so that the upper limit of the network speed cannot be determined.

In order to solve the above problems, the embodiments of the present application provide a method and an electronic device for determining an upper limit of a network speed of a terminal device, which can enable the terminal device to more accurately estimate the upper limit of the network speed, thereby providing a basis for evaluating network quality.

In the embodiment of the application, the terminal device may be a portable terminal capable of being connected to a wireless network through a base station, such as a mobile phone, a tablet computer, a wearable device (such as a smart watch), a vehicle-mounted device, and the like.

The hardware structure of the terminal device provided by the embodiment of the present application is introduced through fig. 2, and the software architecture of the terminal device provided by the embodiment of the present application is illustrated below. It should be noted that, in the embodiment of the present application, the terminal device may also be referred to as an electronic device, and the present application does not distinguish between the two.

The software architecture of the terminal device provided by the embodiment of the present application will be described first.

Fig. 3 is a schematic diagram of a software architecture of a terminal device according to an embodiment of the present application. As shown in fig. 3, the software architecture is an SDAP (SERVICE DATA Adaption Protocol, service data adaptation protocol) layer, a PDCP (PACKET DATA Convergence Protocol ) layer, an RLC (Radio Link Control, radio link Control) layer, a MAC (MEDIA ACCESS Control, media intervention Control) layer, and a PHY (PHYSICAL LAYER, physical) layer in this order from top to bottom.

The SDAP layer is responsible for mapping the QoS (Quality of Service ) flows and the DRB (Data Radio Bearer, data radio bearer). The PDCP layer is responsible for integrity protection, encryption and decryption, reordering and the like; the RLC layer is responsible for unpacking received fragmented packets into complete packets, i.e., group packets, according to an uplink scheduling Grant (UL Grant) for the uplink or for the downlink. The MAC layer is responsible for mapping logical channels (protocol layer) and transport channels (physical layer), and when uplink packets are sent, MAC subPDU (Protocol Data Unit ) are formed into MAC PDUs in units of TB according to the priority of the logical channels, and downlink demultiplexes received data packets, and distributes corresponding data packets to the mapped logical channels according to the sequence numbers of the logical channels.

In the embodiment of the application, the uplink signals sequentially pass through the PDCP layer, the RLC layer and the MAC layer, then reach the PHY layer, and complete transmission through the radio frequency front end and the antenna. After the downlink signal is received by the antenna and the radio frequency front end, the downlink signal passes through the PHY layer, the MAC layer, the RLC layer and the PDCP layer in sequence to finish receiving. Thus, references to acquiring an uplink network rate in the subsequent embodiments may refer to acquisition from the PDCP layer, RLC layer, MAC layer or PHY layer. References to acquiring the downlink network rate in the subsequent embodiments may also refer to acquisition from the PDCP layer, RLC layer, MAC layer or PHY layer. This will not be described in detail later.

The above describes the software architecture of the terminal device provided by 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 the terminal device in fig. 3 except for the SDAP layer, which is not described here.

Based on the above description of the hardware structure and the software architecture of the terminal device provided by the embodiment of the present application, a method for determining the upper limit of the network speed of the terminal device provided by the embodiment of the present application is described below. It should be noted that the method may be performed by a module, such as a processor, having a data processing function in the terminal device.

It should be noted that, the method for determining the upper limit of the network speed of the terminal device provided by the embodiment of the present application is used for determining 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 will be appreciated that for a terminal device, the network speed includes an uplink rate and a downlink rate. The uplink rate is used for indicating the rate of sending signals to the base station by the terminal equipment. The downlink rate is used to indicate the rate at which the terminal device receives the signal sent by the base station. The method for determining the upper limit of the network speed of the terminal equipment provided by the embodiment of the application is firstly described below.

Referring to fig. 4, a flowchart of a method for determining an upper limit of a downlink rate of a terminal device according to an embodiment of the present application is provided. As shown in fig. 4, the method includes the following steps.

S401, obtaining the downlink rate, MIMO order of the terminal equipment, and frequency band, reference signal receiving quality, resource block number, signal to interference plus noise ratio of the current wireless network.

In the embodiment of the present application, the downlink rate of the terminal device, the MIMO order may also be referred to as a first parameter of the terminal device. The frequency band, reference signal reception quality, number of resource blocks, signal to interference plus noise ratio of the current wireless network may also be referred to as a second parameter of the wireless network.

The downlink rate of the terminal device refers to the network rate of the downlink of the terminal device. As described above, the downlink rate may be obtained from the PDCP layer, RLC layer, MAC layer or PHY layer of the terminal device, which will not be described herein.

The MIMO (Multiple-In Multiple-Out) order refers to the number of MIMO antennas In an operating state In the terminal device. The terminal device may obtain the MIMO order from its own configuration information.

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 are not described herein.

Reference Signal Received Quality (RSRQ) of the wireless network is used to indicate the signal-to-noise ratio and interference level of the current channel Quality. The larger the value of RSRQ, the better the quality of the received signal. The smaller the value of RSRQ, the worse the quality of the received signal.

According to the definition of RSRQ by 3GPP (3 rd Generation Partnership Project, third generation partnership project), the following formula (1) can be derived:

Wherein RSRP is a reference signal received Power (REFERENCE SIGNAL RECEIVING Power) for indicating the strength of the wireless signal. The RSSI is a received signal strength Indicator (RECEIVED SIGNAL STRENGTH Indicator) that indicates the received signal strength and the interference level of the current channel.

From the definition of RSSI on 3GPP, the following equation (2) can be obtained:

RSSI = 2 xnxrsrp+10 xrsrp×ratio×n+12×s×n formula (2).

Wherein N is the total resource block number corresponding to the actual bandwidth of the wireless network frequency band of the current cell. The Ratio is the resource block utilization of the current wireless network. S is interference and noise.

The number of resource blocks is RB (Resource Block). The RB is used to measure how much of the frequency domain resources and the time domain resources. Specifically, 1 RB may include 12 consecutive subcarriers in the frequency domain and one slot (slot) in the time domain. Where the bandwidth of the sub-carrier is 15KHz and one slot may be 0.5ms or 0.125ms. That is, one RB may include a frequency domain resource of 180Khz and a time domain resource of 1 slot.

Note that, although different RBs include frequency domain resources and time domain resources of the same size, the amount of data carried is not necessarily the same. For example, the signal-to-noise environment can affect the amount of data carried by the RB. The better the signal-to-noise environment, the greater the amount of data carried by 1 RB. The worse the signal-to-noise environment, the smaller the amount of data one RB carries. It can be appreciated that when the base station allocates the same number of RBs to two terminal devices, the terminal device with better signal-to-noise environment has faster network speed, i.e. better network quality.

In the embodiment of the application, the number of the resource blocks of the current wireless network refers to the total RB number corresponding to the actual bandwidth of the wireless network frequency band of the current cell. For example, if the actual bandwidth of the current cell radio network band is 20M bandwidth of LTE, the corresponding total RB number is 100. For another example, if the actual bandwidth of the current cell radio network band is the 100M bandwidth of NR, the corresponding total RB number is 273.

The signal to interference plus noise ratio (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 interfering signal (noise and interference). Can be simply understood as the signal to noise ratio.

According to the definition of SINR on 3GPP, the following equation (3) can be obtained:

in the embodiment of the present application, the terminal device may obtain parameters such as RSSI, RSRP, the number of resource blocks, and the signal-to-interference-and-noise ratio of the current wireless network in the process of performing SRS (Sounding REFERENCE SIGNAL, channel Sounding reference signal) with the base station.

Note that, the relationships between the parameters in the LTE wireless network are indicated by the above formulas (1) to (3). For the NR wireless network, the definition of some parameters is slightly different, and specific reference may be made to IEEE (Institute of ELECTRICAL AND Electronics Engineers ) for the definition of each parameter in the NR wireless network, which is not described herein.

S402, determining the resource block utilization rate of the current wireless network according to the reference signal receiving quality and the signal-to-interference-plus-noise ratio.

For LTE wireless networks, the following equation (4) can be derived based on the above equations (1) to (3):

for NR wireless networks, the following equation (5) can be derived based on the definition of the parameters by IEEE:

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, judging whether the utilization rate of the resource block is more than or equal to 100%. If not, executing S404a; if yes, S404b is executed.

In an embodiment of the present application, 100% may be a possible value of the first preset threshold.

It can be understood that the resource block utilization is greater than or equal to 100%, which indicates that the current air interface has no RB resource available for allocation, and the current downlink rate of the terminal device can be considered as the upper limit of the downlink rate.

And the utilization rate of the resource block is less than 100%, which indicates that the current air interface also has the resource block available for allocation. Therefore, the upper limit of the downlink rate of the terminal equipment can be obtained by calculating the downlink rate which can be provided by the resource block for allocation and adding the calculated downlink rate with the current downlink rate of the terminal equipment.

The following describes the situation that the utilization rate of the resource block is less than 100%, that is, the current air interface has a resource block available for allocation.

S404a, determining a first peak rate of the terminal equipment in a preset database according to the frequency band of the current wireless network, the signal-to-interference-plus-noise ratio, the number of resource blocks and the MIMO (multiple input multiple output) order of the terminal equipment.

The preset database comprises the frequency bands of each wireless network, the signal-to-interference-plus-noise ratio, the number of resource blocks and the corresponding relation between the MIMO order and the peak downlink rate.

Referring to the description of the resource blocks, parameters such as the signal-to-noise environment, the number of resource blocks, the MIMO order of the terminal device and the like affect the amount of data carried by the RB, thereby affecting the network downlink rate of the terminal device.

In the embodiment of the application, the peak downlink rate corresponding to each SINR, MIMO (multiple input multiple output) order and RB (radio frequency) number in different frequency bands can be tested through the off-line test terminal equipment, and the result data of the off-line test is stored and used as a preset database. It can be understood that the preset database is used for indicating the corresponding relations of different signal-to-noise ratios, the number of resource blocks and the MIMO order and the peak downlink rate in the signals of each frequency band.

The preset database may be as shown in table 1 below.

TABLE 1

As shown in table 1, the preset database may include frequency bands, SINR, RB number, MIMO order, and peak rate. The specific procedure of S404a is illustrated below.

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, it may be determined that the peak rate corresponding to the above parameter is 100Mbps according to the above table 1. That is, the first peak rate of the terminal device can be determined to be 100Mbps based on the above parameters.

In other embodiments, the preset database may not have a peak rate corresponding to the parameters acquired in S401, in which case the corresponding RB number and MIMO order may be determined in the preset database according to the SINR acquired in S401, and the peak rate may be converted according to the corresponding RB number and MIMO order.

For example, the first peak rate may be obtained by the following formula (6).

Wherein, rate _{curr_peak} is a first peak Rate, rank _curr refers to the acquired MIMO order of the terminal device, rank _peak refers to the MIMO order of the terminal device in a preset database, RB _curr refers to the acquired number of resource blocks of the current wireless network, RB _peak refers to the number of resource blocks in the preset database, and Rate _peak refers to the peak Rate in the preset database.

For example, 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. It can be determined from the above parameters and Table 1 that Rank _curr is 1, rank _peak is 2, RB _curr is 100, RB _peak is 273, and rate _peak is 100Mbps. Therefore, the first peak rate can be determined to be 18.3Mbps according to the above formula (6).

It should be noted that, the first peak rate calculated by the formula (6) does not consider the current downlink rate of the terminal device, nor does it consider whether the remaining RBs on the base station side can be fully allocated to itself, so that the first peak rate cannot fully represent the actual upper limit of the downlink rate of the terminal device.

S405a, determining a first downlink rate upper limit of the terminal equipment according to the downlink rate of the terminal equipment, the first peak rate and the resource block utilization rate of the current wireless network.

Specifically, the first downlink rate upper limit of the terminal device may be determined by the following formula (7).

Rate_dl=λ× (1-Ratio) ×Rate _{curr_peak}+Rate_curr equation (7).

Wherein lambda is a preset coefficient, the value range is between 0 and 1, and 0 and 1 are not included. Rate_dl is the first upper downlink Rate limit of the terminal device. Substituting the Ratio calculated in the formula (4) or the formula (5), the Rate _{curr_peak} calculated in the formula (6) and the downlink Rate of the terminal equipment acquired in the step S401 into the formula (7), and then calculating to obtain a first downlink Rate upper limit of the terminal equipment.

The preset coefficient is introduced because the remaining air interface resources of the wireless network are not necessarily all allocated to the terminal equipment, so that the rate corresponding to the remaining air interface resources is multiplied by the preset coefficient, and the calculation result can more accurately reflect the rate corresponding to the bandwidth which can be allocated to the terminal equipment by the base station.

In the embodiment of the present application, the first upper downlink rate limit of the terminal device obtained in S405a may be compared with the AMBR (AGGREGATE MAXIMUM BIT RATE, total maximum bit rate) of the terminal device, and the smaller value of the two may be used as the finally determined upper downlink rate limit of the terminal device. Namely S406a described below.

S406a, taking the smaller value of the first downlink rate upper limit of the terminal equipment and the total maximum bit rate of the terminal equipment as the downlink rate upper limit of the terminal equipment.

The AMBR may be understood as an upper rate limit set by the core network side when the core network side opens an account for the terminal device, and the base station allocates an air interface resource to the terminal device generally does not exceed the upper rate limit. Therefore, when the calculated first downlink rate upper limit is greater than the AMBR, the AMBR is used as the actual downlink rate upper limit of the terminal equipment, and the accuracy is higher.

The following describes the case where the resource block utilization is greater than or equal to 100%, i.e. there is no resource block available for allocation on the current air interface.

S404b, determining the upper limit of the downlink rate of the terminal equipment according to the downlink rate of the terminal equipment.

In this case, the base station does not have more RBs allocated to the terminal device, and thus the downlink rate of the terminal device, i.e., the upper limit of the downlink rate.

The method for determining the upper limit of the downlink rate of the terminal device is described above through fig. 4. The method for determining the uplink rate upper limit of the terminal device is described below.

Referring to fig. 5, a flowchart of a method for determining an uplink rate upper limit of a terminal device according to an embodiment of the present application is provided. As shown in fig. 5, the method includes the following steps.

S501, obtaining uplink buffer time, maximum transmitting power, current transmitting power, uplink speed, number of divided resource blocks, reference signal receiving quality, number of resource blocks and signal-to-interference-plus-noise ratio of the current wireless network of the terminal equipment.

The uplink rate, the maximum transmission power, the current transmission power, the total maximum bit rate of the terminal device, and the number of divided resource blocks may also be referred to as a third parameter of the terminal device. The number of resource blocks of the wireless network, the signal to interference plus noise ratio, and the reference signal reception quality may also be referred to as a fourth parameter of the wireless network.

The uplink buffer time is the time for waiting for the base station scheduling of the data message to be sent by the terminal equipment side, namely the time for the terminal equipment to request the base station to schedule resources, and can be used for evaluating the congestion degree of the current uplink resources. Referring to fig. 6, a flowchart of a terminal device requesting a base station to schedule resources is provided in an embodiment of the present application. As shown in fig. 6, the process includes the following steps.

S601, the terminal equipment sends an authorization request to the base station at a first moment.

The authorization request is used for requesting the base station to indicate when the data message can be sent.

S602, after receiving the authorization request at the second moment, the base station issues scheduling resources to the terminal equipment at the third moment.

The scheduling resource issued by the base station is used for indicating the terminal equipment to send the data message at the fifth moment.

S603, after receiving the scheduling resource issued by the base station at the fourth moment, the terminal equipment starts to send the data message at the fifth moment.

In the process that the terminal equipment requests the base station to schedule resources, the first moment is written as t1, the fifth moment is written as t5, and then the uplink buffer time is t5-t1.

The maximum transmit power is typically constant for the terminal device. The antenna conduction Power of the terminal device may be, for example, PC2 (Power Class 2 ), i.e. 26dBm, or PC3 (Power Class 3 ), i.e. 23dBm. Where dBm (decibel relative to one milliwatt, decibel milliwatts) is a unit of power used to indicate the absolute value of power. The conversion of decibel-to-milli-watts may be achieved by the following equation (8).

P= (1 mW) ×10 ^(x/10) formula (8).

Where P is milliwatts and x is decibel milliwatts.

S502, judging whether the uplink buffer time of the terminal equipment is larger than a preset threshold value. If not, execution proceeds to S503a. If yes, S503b is executed.

In the embodiment of the present application, the preset threshold may be 50ms,60ms, etc., which is not limited herein.

The uplink buffer time of the terminal equipment is larger than a preset threshold value, which indicates that the current network is more congested, so that the current uplink rate of the terminal equipment is the upper limit of the uplink rate.

And the uplink buffer time of the terminal equipment is smaller than a preset threshold value, which indicates that the current network still has a margin, so that the uplink rate upper limit can be further determined.

The case where the uplink buffer time of the terminal device is smaller than the preset threshold will be described first.

S503a, determining the utilization rate of the resource block of the current wireless network according to the reference signal receiving quality of the current wireless network and the signal-to-interference-plus-noise ratio.

The specific calculation process can be referred to the foregoing formula (4) and formula (5), and will not be described herein.

S504a, determining a first rate according to the uplink rate of the terminal equipment, the current transmitting power of the terminal equipment and the number of resource blocks obtained by the terminal equipment.

The first rate is used to indicate the contribution to the uplink rate per power unit and per resource block.

In embodiments of the present application, the process of determining the first rate may include a number of steps, as exemplified below.

First, a first rate is calculated according to an uplink rate of the terminal device, a current transmitting power and a number of resource blocks obtained by the terminal device.

The uplink Rate of the terminal device is called Rate _{up_curr}, the current transmitting Power is called Power _actual, and the number of resource blocks allocated by the terminal device is called Count _{RB_UE}. The first Rate _{perPower_RB} can be calculated by the following equation (9).

The first rate is used to indicate the contribution to the uplink rate per power unit and per resource block. Therefore, the power margin and the resource block margin may be multiplied by the first rate to obtain a margin of the uplink rate, and further obtain the theoretical uplink rate upper limit of the terminal device, that is, S505a described below.

S505a, determining a first uplink rate upper limit according to the first rate, the uplink rate of the terminal equipment, the maximum transmission power, the current transmission power and the number of resource blocks of the current wireless network, and the resource block utilization rate.

In an embodiment of the present application, the process of determining the first rate may also include a plurality of steps, as exemplified below.

First, a power headroom is calculated from a maximum transmit power of a terminal device, a current transmit power. It is understood that the power margin is the difference between the maximum transmit power and the current transmit power.

And secondly, calculating the resource block allowance according to the number of the resource blocks and the resource block utilization rate of the current wireless network. It can be appreciated that the resource block margin is the product of 1 and the difference in resource block utilization times the number of resource blocks.

Next, an uplink rate margin is calculated from the power margin, the resource block margin, and the first rate. As described above, the uplink rate margin, i.e., the product of the power margin, the resource block margin, and the first rate.

Finally, the sum of the uplink rate and the uplink rate allowance of the terminal equipment is the first uplink rate upper limit.

The uplink Rate margin is called Rate _spare, the resource block utilization is called Ratio, the number of resource blocks is called Count _{RB_Cell}, the maximum transmission Power is called Power _max, the uplink Rate of the terminal device is called Rate _{up_curr}, the first uplink Rate upper limit is called rate_up, and the first uplink Rate upper limit can be calculated according to the following formula (10).

Rate_up=count _{RB_Cell}×(1-Ratio)×Rate_{perPower_RB}×(Power_max-Power_actual)+Rate_{up_curr} equation (10).

In the embodiment of the application, the first uplink rate upper limit is only the theoretical uplink rate upper limit of the terminal equipment. When the first uplink rate upper limit is less than or equal to AMBR, the first uplink rate upper limit may be used as an actual uplink rate upper limit of the terminal device. And when the first uplink rate upper limit is greater than the AMBR, the base station allocates the air interface resource to the terminal device, which generally does not exceed the AMBR, so that the AMBR is the actual uplink rate upper limit of the terminal device.

S506a, taking the smaller value of the first uplink rate upper limit of the terminal equipment and the total maximum bit rate of the terminal equipment as the uplink rate upper limit of the terminal equipment.

The above description of S503a-S506a describes the procedure 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 process of determining the actual uplink rate upper limit of the terminal device when the uplink buffer time of the terminal device is greater than or equal to the preset threshold will be described below.

S503b, determining the uplink rate upper limit of the terminal equipment according to the uplink rate of the terminal equipment.

Based on the above description, the method for determining the network speed upper limit of the terminal device provided by the embodiment of the application can relatively accurately calculate the network speed upper limit corresponding to the maximum bandwidth which can be allocated to the terminal device by the base station at the terminal device side, thereby providing a basis for measuring the network quality of the terminal device.
