Based on the description in the background art, because in the related art, the network optimization mode which depends on only one parameter of the MOS may not be comprehensive, and the call quality of the terminal when performing the voice service cannot be ensured quickly and effectively. Based on this, the embodiment of the invention provides a network optimization method, an apparatus, an electronic device and a storage medium, because the first correspondence includes the RSRP of the first terminal at each time and the MOS corresponding to the RSRP of the first terminal at each time (specifically, the MOS of the second terminal at each time), and the second correspondence includes the SINR of the first terminal at each time and the MOS corresponding to the SINR of the first terminal at each time (specifically, the MOS of the first terminal at each time), that is, the electronic device may associate the wireless environment (specifically, RSRP) of the first terminal with the MOS of the second terminal, and associate the wireless environment (specifically, SINR) of the first terminal with the MOS of the first terminal, so as to accurately characterize the relationship between the wireless environment and the call quality. Therefore, the electronic equipment can optimize the network based on the parameters included in the first corresponding relation (and/or the second corresponding relation), particularly MOS (metal oxide semiconductor) and RSRP (and/or SINR), so that the call quality of the terminal in voice service can be effectively ensured, and the user satisfaction degree is improved.
The network optimization method, device, electronic equipment and storage medium provided by the embodiment of the invention can be applied to a network optimization system, as shown in fig. 1, wherein the network optimization system comprises a terminal 101, a terminal 102, a server 103, an electronic equipment 104 and a server 105. In general, in practical applications, the connection between the above-mentioned devices or service functions may be a wireless connection, and for convenience and intuitiveness, the connection relationship between the devices is schematically shown by a solid line in fig. 1.
Wherein the terminal 101 may obtain a voice sample from the server 103 and send the voice sample to the terminal 102 via an associated network device (not shown).
After receiving the above-described voice sample, the terminal 102 records voice data corresponding to the voice sample, and transmits the voice data to the server 103.
In the embodiment of the present invention, the terminal 101 and the terminal 102 are further configured to obtain respective radio environment information, where the radio environment information includes a reference signal received power (REFERENCE SIGNAL RECEIVING power, RSRP) and a signal-to-interference-plus-noise ratio (signal to interference plus noise ratio, SINR).
The server 103 is configured to perform a comparison process on the voice sample and the voice data to obtain a MOS when the voice service is performed between the terminal 101 and the terminal 102, and send the MOS to the electronic device 104.
An electronic device 104 for receiving the MOS transmitted by the server 103, the wireless environment information of the terminal 101 (and the terminal 102) transmitted by the terminal 101 (and the terminal 102), and the location information corresponding to each piece of wireless environment information transmitted by the server 105.
The server 105 is configured to determine location information corresponding to each piece of wireless environment information, and send the location information corresponding to each piece of wireless environment information to the electronic device 104.
Alternatively, the server 103 may be a MOS box, and the server 105 may be a global positioning system (global positioning system, GPS) server.
It should be noted that the number of the respective devices shown in fig. 1 is only an example of the embodiment of the present invention, and the embodiment of the present invention does not specifically limit the number of the respective devices.
By way of example, the electronic device 104 may be a cell phone, tablet, desktop, laptop, handheld computer, notebook, ultra-mobile personal computer (UMPC), netbook, cell phone, personal Digital Assistant (PDA), augmented reality (augmented reality, AR) \virtual reality (VR) device, etc., and the invention is not limited to the specific form of the electronic device 104. The system can perform man-machine interaction with a user through one or more modes of a keyboard, a touch pad, a touch screen, a remote controller, voice interaction or handwriting equipment and the like.
Optionally, the electronic device 104 may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, network acceleration services (content delivery network, CDN), and basic cloud computing services such as big data and artificial intelligence platforms.
The network optimization method, the network optimization device, the electronic equipment and the storage medium provided by the embodiment of the invention are applied to a scene of voice communication between one terminal (such as a first terminal) and another terminal (such as a second terminal). Specifically, after determining the wireless environment information of the first terminal at each of the plurality of moments and the wireless environment information of the second terminal at each of the moments, the electronic device may optimize the target network based on the generated first correspondence and/or the generated second correspondence.
As shown in fig. 2, the network optimization method provided by the embodiment of the present invention may include S101-S104.
S101, the electronic device determines wireless environment information of a first terminal at each of a plurality of moments and wireless environment information of a second terminal at each moment.
The wireless environment information comprises RSRP and SINR, the plurality of moments are moments included in a preset time period, and the first terminal and the second terminal transmit voice samples in the preset time period.
It should be understood that, the first terminal and the second terminal transmitting the voice sample in the preset time period is that the first terminal and the second terminal perform a voice call in the preset time period. The voice service data transmitted when the first terminal and the second terminal carry out voice communication are the voice samples. Specifically, the first terminal and the second terminal may complete a communication process between the first terminal and the second terminal and a transmission process of a voice sample through corresponding network devices.
It can be appreciated that the electronic device determining the wireless environment information of the first terminal at each time instant is determining the RSRP of the first terminal at each time instant and the SINR of the first terminal at each time instant.
In the embodiment of the present invention, the RSRP of the first terminal at a certain moment may be understood as the signal strength (or field strength) of the first terminal at the certain moment, and the SINR of the first terminal at the certain moment may be understood as the signal quality (or interference condition) of the first terminal at the certain moment. In the embodiment of the invention, the electronic device can determine the network quality of the network where the first terminal is located based on the RSRP (and/or SINR) of the first terminal at a certain moment. Specifically, when the RSRP is large and the SINR is small, it is indicated that the network quality is superior.
In one implementation manner of the embodiment of the present invention, the first terminal may be placed on top of a mobile test device, where the mobile test device may be an unmanned vehicle, an unmanned plane, or a common test vehicle, and the first terminal needs to be exposed outdoors without shielding, so as to avoid loss and error of wireless signals caused by shielding. The second terminal may also be placed at the very point of the relevant network device, e.g. a base station. Specifically, the mobile test device may move at a certain movement speed (for example, the movement speed may be less than or equal to 40 km/h) in each line included in the target area (i.e., the area corresponding to the target network), where during the movement, the first terminal may initiate a voice service with the second terminal through the network device, and transmit a voice sample and so on.
It should be noted that the RSRP of the above-mentioned excellent point should be greater than or equal to the RSRP threshold (for example, -70dbm (decibel-milliwatt)), and the SINR of the excellent point should be less than or equal to the SINR threshold (for example, 30 db).
As shown in fig. 3, it is assumed that the terminal 201 is the first terminal, and the terminal 203 is the second terminal. Terminal 201 may send the voice sample to network device 202 in uplink direction 1 (i.e., uplink direction of terminal 201 and network device 202), and network device 202 may send the voice sample to terminal 203 in downlink direction 1 (i.e., downlink direction of network device 202 and terminal 203). Terminal 203 may send the voice sample to network device 202 in uplink direction 2 (i.e., uplink direction of terminal 203 and network device 202), and network device 202 may send the voice sample to terminal 201 in downlink direction 2 (i.e., downlink direction of network device 202 and terminal 201).
S102, the electronic equipment determines the MOS of the first terminal at each moment and the MOS of the second terminal at each moment.
It should be understood that the MOS of the first terminal at a certain moment may characterize the call quality of the terminal at that moment. Specifically, when the MOS of the first terminal at the moment is higher, the communication quality of the first terminal at the moment is better; when the MOS of the first terminal at the moment is lower, the communication quality of the first terminal at the moment is poorer.
For example, table 1 below is an example of a MOS and user satisfaction provided in an embodiment of the present invention. In particular, the call quality can be classified into good, medium, bad, and bad.
TABLE 1
Quality of conversation MOS User satisfaction
Excellent (excellent) (4.0，5.0] Very good, and can be heard clearly without distortion and delay
Good grade (good) (3.5，4.0] Slightly worse, audible clarity, small delay and somewhat murmur
In (a) (2.5，3.5] It is also possible that the hearing is not clear, there is a delay and there is distortion
Difference of difference (1.5，2.5] The hearing is unclear, has larger noise and serious distortion
Inferior quality (0.0，1.5] Very bad, silent or completely inaudible, very loud murmur
Assuming that the MOS of the first terminal at a certain time is 4.5, it is explained that the call quality of the first terminal at the certain time is excellent, and the user satisfaction of the user using the first terminal at the certain time is: the method is very good, can be heard clearly, and has no distortion sense and no delay sense.
In one implementation of the embodiment of the present invention, voice traffic at different voice coding rates may correspond to different MOSs at different RSRP (or SINR). Specifically, if the speech coding rate of the first speech service is greater than the speech coding rate of the second speech service, the MOS of the first speech service is greater than the MOS of the second speech service at the same RSRP (or the same SINR).
By way of example, long term evolution voice bearer (voice over long term evolution, voLTE) traffic can be divided into adaptive multi-rate narrowband speech coding (adaptive multi rate-narrow band speech codec, AMR-NB) 12.2kbps (kilobits per second) traffic, adaptive multi-rate wideband speech coding (adaptive multi rate-wide band speech codec, AMR-WB) 12.65kbps traffic, and AMR-WB 23.85kbps traffic.
As shown in fig. 4 and fig. 5, the corresponding diagrams of RSRP and MOS in VoLTE service and SINR and MOS in VoLTE service are respectively shown. In particular, line L1 is used to characterize AMR-WB 23.85kbps traffic, line L2 is used to characterize AMR-WB 12.65kbps traffic, and line L3 is used to characterize AMR-NB 12.2kbps traffic.
It should be noted that the embodiment of the present invention is not limited to the execution sequence of S101 and S102. For example, S101 may be performed first and then S102 may be performed, or S102 may be performed first and then S101 may be performed, or S101 and S102 may be performed simultaneously. S101 and S102 are taken as examples in fig. 2.
S103, the electronic equipment generates a first corresponding relation and a second corresponding relation.
The first corresponding relation comprises RSRP of the first terminal at each moment and MOS corresponding to the RSRP of the first terminal at each moment, the second corresponding relation comprises SINR of the second terminal at each moment and MOS corresponding to the SINR of the second terminal at each moment, the MOS corresponding to the RSRP of the second terminal at each moment is MOS of the second terminal at each moment, and the MOS corresponding to the SINR of the first terminal at each moment is MOS of the first terminal at each moment.
In connection with the description of the above embodiments, it should be understood that the electronic device may determine the RSRP of the first terminal at the each time instant, the SINR of the first terminal at the each time instant, the RSRP of the second terminal at the each time instant, and the SINR of the second terminal at the each time instant.
It will be appreciated that RSRP is used to reflect the case of an uplink channel (or uplink direction) and SINR is used to reflect the case of a downlink channel (or downlink direction). Since the second terminal is located at the very good point of the network device, in the embodiment of the present invention, the downlink direction between the network device and the second terminal (i.e. the downlink direction 1 in fig. 3) and the uplink direction between the second terminal and the network device (i.e. the uplink direction 2 in fig. 3) may not be considered, i.e. the embodiment of the present invention may not consider the SINR of the second terminal and the RSRP of the second terminal. In this way, the electronic device may associate the RSRP of the first terminal at each time with the MOS of the second terminal at each time to generate the first correspondence, and associate the SINR of the first terminal at each time with the MOS of the first terminal at each time to generate the second correspondence.
In the embodiment of the present invention, since the RSRP of the first terminal at each time and the SINR of the first terminal at each time are information (or parameters) included in the wireless environment information of the first terminal at each time, that is, the RSRP of the first terminal at each time and the SINR of the first terminal at each time may represent the wireless environment where the first terminal is located. Thus, the electronic device can associate the wireless environment where the first terminal is located with the call quality (including the MOS of the first terminal at each moment and the MOS of the second terminal at each moment), so that the relationship between the wireless environment and the call quality can be accurately represented.
For example, table 2 below is an example of the first correspondence provided in the embodiment of the present invention. The first correspondence relationship includes 8 times (specifically, 1 second(s) represents one time). Specifically, the RSRP of the first terminal at the time of 10:08:01 is-89.39 dbm, the MOS of the second terminal at the time of 10:08:01 is 4.29, and other RSRP and MOS included in the first correspondence may be obtained from the table 2, which is not described herein.

And S104, the electronic equipment optimizes the target network based on the first corresponding relation and/or the second corresponding relation.
It should be understood that the target network is a communication network where the first terminal and the second terminal are located, and may also be understood as a network covered by the above network device. In the embodiment of the invention, the electronic device optimizes the target network based on the first corresponding relation, namely, optimizes the target network based on the RSRP of the first terminal at each moment in a plurality of moments and the MOS corresponding to the RSRP of each moment. Specifically, the terminal in the target network needs to satisfy one MOS, and the electronic device may determine, based on the RSRP corresponding to the MOS, the RSRP that needs to be satisfied by the target network, and then perform site planning, site selection, construction, and the like based on the RSRP that needs to be satisfied.
The technical scheme provided by the embodiment at least has the following beneficial effects: as known from S101-S104, the electronic device may determine radio environment information (including RSRP and SINR) of the first terminal at each of a plurality of times and radio environment information of the second terminal at the each time, and determine MOS of the first terminal at the each time and MOS of the second terminal at the each time; the electronic device may then generate a first correspondence and a second correspondence, and optimize the target network based on the first correspondence and/or the second correspondence. In the embodiment of the present invention, since the first correspondence includes the RSRP of the first terminal at each time and the MOS corresponding to the RSRP of the first terminal at each time (specifically, the MOS corresponding to the SINR of the second terminal at each time), and the second correspondence includes the SINR of the first terminal at each time and the MOS corresponding to the SINR of each time (specifically, the MOS corresponding to each time of the first terminal), that is, the electronic device may associate the radio environment (specifically, the RSRP) of the first terminal with the MOS of the second terminal, and associate the radio environment (specifically, the SINR) of the first terminal with the MOS of the first terminal, so that the relationship between the radio environment and the call quality can be accurately represented. Therefore, the electronic equipment can optimize the network based on the parameters included in the first corresponding relation (and/or the second corresponding relation), particularly MOS (metal oxide semiconductor) and RSRP (and/or SINR), so that the call quality of the terminal in voice service can be effectively ensured, and the user satisfaction degree is improved.
Referring to fig. 2, as shown in fig. 6, in an implementation manner of the embodiment of the present invention, the determining, by the electronic device, the MOS of the first terminal at each moment may specifically include S1021-S1023.
S1021, the electronic device acquires at least one MOS included in a preset time period of the first terminal.
In connection with the above description with respect to fig. 1, it should be understood that the electronic device may obtain, from the above server 103 (specifically, may be a MOS box), at least one MOS included in the first terminal during the preset period.
It will be appreciated that in the process of generating the MOS of the first terminal by the MOS box (or in the process of acquiring the MOS of the first terminal by the electronic device), instead of generating one MOS at each time (for example, every 1S), a target duration is spaced between the time of generating the current MOS and the time of generating the last MOS (or the time of generating the next MOS), and the target duration may be greater than or equal to the duration (for example, 8S) characterized for the above-mentioned voice sample.
For example, assuming that the current MOS generation time is 10:08:04 and the target duration is 8S, it is explained that the next MOS generation time is 10:08:12.
S1022, the electronic device determines the time corresponding to each MOS in the at least one MOS.
It should be understood that the time corresponding to each MOS is the generation time of each MOS, that is, the time when the MOS box generates each MOS.
And S1023, when the corresponding MOS does not exist at the first moment, the electronic equipment determines the MOS corresponding to the second moment as the MOS of the first terminal at the first moment.
The first time is one of the multiple times, and the second time is a first time after the first time when the corresponding MOS exists.
In connection with the description of the above embodiments, it should be understood that not every instant of the above plurality of instants has a corresponding MOS. When the first time does not have a corresponding MOS, it indicates that the first time is not a time corresponding to one of the at least one MOS, and the electronic device may determine the second time from at least one time (i.e., a time corresponding to each of the at least one MOS), where the second time is a first time located after the first time in the at least one time.
For example, table 3 below shows an example of 2 MOS devices included in a preset period of time, where the first terminal is acquired by the electronic device according to the embodiment of the present invention. Specifically, the time corresponding to the first MOS (i.e., 4.29) of the 2 MOSs is 10:08:04, and the time corresponding to the second MOS (i.e., 3.95) is 10:08:12.

Assuming that the first time is 10:08:06, the electronic device determines that the second time is 10:08:12, and the MOS of the first terminal at the first time is 3.95.
In an optional implementation manner, when the corresponding MOS exists at the first time, the corresponding MOS at the first time is the MOS of the first terminal at the first time.
It should be noted that, the explanation of the MOS of the electronic device for determining the second terminal at each time is the same as or similar to the description of the MOS of the electronic device for determining the first terminal at each time, which is not repeated herein.
The technical scheme provided by the embodiment at least has the following beneficial effects: as known from S1021-S1023, the electronic device may acquire at least one MOS included in the first terminal in the preset period, and determine a time corresponding to each MOS in the at least one MOS; when there is no corresponding MOS at a certain time (e.g., a first time) of the plurality of times, the electronic device may determine the MOS corresponding to the second time (i.e., a first time after the first time at which there is the corresponding MOS) as the MOS of the first terminal at the first time. The method and the device can conveniently and quickly determine each time when the corresponding MOS exists, and add the corresponding MOS for each time when the corresponding MOS does not exist, so that the determination efficiency of the MOS of the first terminal at each time can be improved.
Referring to fig. 2, as shown in fig. 7, in an implementation manner of the embodiment of the present invention, the electronic device optimizes the target network based on the first correspondence, which may specifically include S1031-S1033.
S1031, the electronic equipment divides the plurality of RSRP into at least two RSRP sections according to a preset step length.
Each RSRP section of the at least two RSRP sections includes a minimum RSRP and a maximum RSRP, and the RSRP is the RSRP included in the first correspondence.
In connection with the description of the above embodiment, it should be understood that the first correspondence relationship includes the RSRP of the first terminal at each of a plurality of times and the MOS corresponding to the RSRP of each time (specifically, the MOS of the second terminal at each time), that is, the RSRP of the first terminal at each time.
It may be understood that the electronic device dividing the plurality of RSRP into at least two RSRP intervals according to a preset step size may specifically be determining a minimum value of the plurality of RSRP as a minimum RSRP in a first RSRP interval, and determining an RSRP obtained by adding the preset step size to the minimum value as a maximum RSRP in the first RSRP interval; and then determining the maximum RSRP in the first RSRP interval as the minimum in the second RSRP interval, and so on to obtain the at least two RSRP intervals.
Alternatively, the preset step size may be greater than or equal to 1db.
For example, assuming that the minimum value of the plurality of RSRPs is-116 dbm, the maximum value of the plurality of RSRPs is-94 dbm, and the preset step size is 2db, the electronic device may divide the plurality of RSRPs into 11 RSRP sections. Specifically, the 11 RSRP intervals include [-116dbm,-114dbm]、[-114dbm,-112dbm]、[-112dbm,-110dbm]、[-110dbm,-108dbm]、[-108dbm,-106dbm]、[-106dbm,-104dbm]、[-104dbm,-102dbm]、[-102dbm,-100dbm]、[-100dbm,-98dbm]、[-98dbm,-96dbm] and [ -96dbm, -94dbm ].
S1032, the electronic device determines the MOS corresponding to each RSRP section according to the MOS corresponding to each RSRP included in each RSRP section.
In an implementation manner of the embodiment of the present invention, the electronic device may determine, as the MOS corresponding to each RSRP interval, an average value of the MOS corresponding to each RSRP included in the each RSRP interval.
In another implementation manner of the embodiment of the present invention, the electronic device may also determine a median value of the MOS corresponding to each RSRP included in each RSRP interval as the MOS corresponding to each RSRP interval.
In another implementation manner of the embodiment of the present invention, the electronic device may further determine a value of MOS cumulative distribution function (cumulative distribution function, CDF) =5% (or a value of MOS cdf=10%) of each RSRP section according to the MOS corresponding to each RSRP included in the each RSRP section, and determine the value of MOS cdf=5% of the each RSRP section as the MOS corresponding to the each RSRP section.
Illustratively, as shown in fig. 8, in combination with the example in S1031, a line L4 is used to characterize the MOS corresponding to each of the 11 RSRP intervals determined based on the median value of the MOS. Line L5 is used to characterize the MOS for each of the 11 RSRP intervals determined based on the average of the MOS. Line L6 is used to characterize the determination of the value of MOS cdf=10% for each RSRP interval as the corresponding MOS for that each RSRP interval. Line L7 is used to characterize the determination of the value of MOS cdf=5% for each RSRP interval as the corresponding MOS for that each RSRP interval.
S1033, the electronic equipment determines the maximum RSRP in the target RSRP interval as the minimum RSRP of the target network.
The target RSRP interval is one of at least one RSRP interval corresponding to a preset MOS, the preset MOS is the minimum MOS of the target network, the minimum RSRP in the target RSRP interval is smaller than the minimum RSRP in other RSRP intervals, and the other RSRP intervals are RSRP intervals except the target RSRP interval in the at least one RSRP interval.
It is to be understood that one MOS (e.g., a preset MOS) may correspond to one or more RSRP intervals (i.e., at least one RSRP interval). In the embodiment of the present invention, the electronic device may determine, as the target RSRP section, a minimum RSRP section (which may also be understood as an RSRP section including a minimum RSRP or an RSRP section including a maximum RSRP) of the at least one RSRP section.
Illustratively, in combination with the example in fig. 8 described above, it is assumed that the MOS corresponding to each RSRP section described above is a value of MOS cdf=10% for that each RSRP section (see line L6 in the figure for details), and the preset MOS described above is 3.9. The electronic device determines that at least one RSRP interval corresponding to the preset MOS includes [ -114dbm, -112dbm ] and [ -110dbm, -108dbm ], and determines [ -114dbm, -112dbm ] as the target RSRP interval. And the electronic device determines-112 dbm as the minimum RSRP of the target network.
In an optional implementation manner, the electronic device may further divide the plurality of SINRs included in the second correspondence into at least two SINR intervals according to a preset step size, and determine, according to the MOS corresponding to each SINR included in each of the at least two SINR intervals, the MOS corresponding to each SINR interval. The electronic device may then determine a maximum RSRP in a target SINR interval, which is one of the at least one SINR intervals corresponding to the preset MOS, as a minimum SINR of the target network, where the minimum SINR of the target SINR interval is smaller than a minimum SINR of other SINR intervals, which are SINR intervals of the at least one SINR interval other than the target SINR interval.
It should be noted that, the process of determining the minimum SINR of the target network by the electronic device is the same as or similar to the description in the foregoing determination of the minimum RSRP of the target network by the electronic device, which is not repeated herein.
As shown in fig. 9, an embodiment of the present invention provides a schematic diagram of an MOS, where each SINR interval determined by an electronic device corresponds to each SINR interval. Specifically, a line La is used to represent the MOS corresponding to each SINR interval determined based on the median of the MOS. Line Lb is used to characterize the MOS corresponding to each SINR interval determined based on the average of the MOS. Line Lc is used to characterize the determination of the value of MOS cdf=10% for each SINR interval as the corresponding MOS for that each SINR interval. Line Ld is used to characterize the determination of the value of MOS cdf=5% for each SINR interval as the corresponding MOS for that each SINR interval.
The technical scheme provided by the embodiment at least has the following beneficial effects: the step S1031-step S1033 may be that the electronic device divides the plurality of RSRP into at least two RSRP intervals according to a preset step, and determines the MOS corresponding to each RSRP interval according to the MOS corresponding to each RSRP included in each RSRP interval in the at least two RSRP intervals; the electronic device may then determine a maximum RSRP in the target RSRP interval as a minimum RSRP of the target network. In the invention, the electronic device can divide a plurality of RSRPs according to a preset step length, determine MOS corresponding to each divided RSRP interval, and determine the maximum RSRP in the minimum RSRP interval (particularly, the minimum RSRP in the target RSRP interval is smaller than the minimum RSRP interval in other RSRP intervals) as the minimum RSRP of the target network. The minimum RSRP of the target network can be accurately and effectively determined, and the electronic equipment can perform network optimization based on the minimum RSRP, so that the effectiveness of network optimization can be improved.
In one implementation manner of the embodiment of the present invention, the current time is one of the multiple times, and in conjunction with fig. 2, as shown in fig. 10, the electronic device determines the RSRP of the current time, which may specifically include S1011-S1012.
S1011, the electronic equipment acquires at least two RSRPs included in a preset duration.
The preset time length is the difference between the next time of the current time and the current time.
It is to be appreciated that at least two RSRP may exist (or be included) between the current time and a time next to the current time, each of which may be acquired by the electronic device. Similarly, at least two RSRP may also exist (or be included) between the previous time of the current time and the current time, and each of the at least two RSRP may be acquired by the electronic device.
S1012, the electronic equipment determines an average value of at least two RSRPs as the RSRP at the current moment.
In an alternative implementation, the electronic device may further acquire at least two SINRs included in the preset duration, and determine an average value of the at least two SINRs as the SINR of the current time. Thus, the electronic device may determine the radio environment information of the current time, that is, the RSRP including the current time and the SINR of the current time.
The technical scheme provided by the embodiment at least has the following beneficial effects: as is known from S1011-S1012, the electronic device may acquire at least two RSRPs included in a preset duration (specifically, a difference between a time next to the current time and the current time), and determine an average value of the at least two RSRPs as the RSRP of the current time. In the invention, because more than one RSRP (at least two RSRPs) possibly exists between two adjacent moments, the electronic equipment can determine the average value of the at least two RSRPs as the RSRP of the previous moment (the current moment) in the two adjacent moments, and can accurately determine the RSRP of each moment, thereby improving the generation efficiency of the first corresponding relation and the second corresponding relation.
