All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the objects identified as "first," "second," etc. are generally a class and do not limit the number of objects.
The terminal network scheduling method, apparatus, electronic device and readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 1 and fig. 2, an embodiment of the present application provides a terminal network scheduling method, including:
A radio network cell, i.e. a cellular cell, refers to an area covered by a base station or a part of a base station in a cellular mobile communication system, in which a mobile station can reliably communicate with the base station through a radio channel.
The radio network cell may be, for example, an NR cell, i.e. an area covered by one or a part of a base station in case of a type of 5G network of a cellular mobile communication system.
For example, the wireless network cell may be a cell under Long Term Evolution (LTE) of the universal mobile telecommunications technology, and details thereof are not repeated herein.
The downlink average rate may be understood as an average value of downlink rates in a period, where the downlink rate generally refers to a rate at which a terminal downloads data from a base station in a case of a wireless network cell to which the terminal accesses.
In some embodiments in the application, the duration of one period may be taken as required by actual use, for example, taken in 2 seconds to 8 seconds, and specific values thereof are not described herein again. For example, the duration of one cycle is 5 seconds, and the duration of another cycle is 3 seconds.
And step 104, performing network scheduling processing according to the parameter value of the signal environment parameter of the wireless network cell under the condition that the monitored downlink average rate is less than or equal to the rate threshold value.
Illustratively, when the terminal is accessed to a wireless network cell in a 5G network environment, the downlink average rate of the terminal is monitored, and the downlink average rate is compared with a rate threshold corresponding to the 5G network environment, so that when the downlink average rate is less than or equal to the rate threshold corresponding to the 5G network environment, it is considered that downlink congestion exists.
For example, when it is monitored that the downlink average rate is 580kbps, the rate threshold corresponding to the 5G network environment is 640kbps, and at this time, when the downlink average rate is smaller than the rate threshold corresponding to the 5G network environment, it is considered that downlink congestion exists, and then network scheduling processing is performed according to the parameter value of the signal environment parameter of the wireless network cell.
Illustratively, when the terminal is accessed to a wireless network cell in an LTE network environment, the downlink average rate of the terminal is monitored, and the downlink average rate is compared with a rate threshold corresponding to the LTE network environment, so that when the downlink average rate is less than or equal to the rate threshold corresponding to the LTE network environment, it is considered that downlink congestion exists.
For example, when it is monitored that the average downlink rate is 380kbps, the rate threshold corresponding to the LTE network environment is 500kbps, and at this time, when the average downlink rate is smaller than the rate threshold corresponding to the LTE network environment, it is considered that downlink congestion exists, and then network scheduling processing is performed according to the parameter value of the signal environment parameter of the wireless network cell.
And the parameter values of the signal environment parameters in different value ranges correspond to different network scheduling processes.
Specifically, when the average value of the channel quality indicators is greater than the first average threshold, the corresponding network scheduling processing is: and reducing the receiving power of the reference signal reported to the base station so that the base station controls the terminal to switch the accessed wireless network cell.
Specifically, when the average value of the channel quality indicator is smaller than the second average threshold and the reference signal received power of the wireless network cell is greater than the second power threshold, the corresponding network scheduling processing is: and disconnecting the network connection with the wireless network cell, and reducing the reselection priority of the wireless network cell so as to enable the base station to send switching information to the terminal, and control the terminal to switch the accessed wireless network cell according to the switching information.
Specifically, when the average value of the channel quality indicator is smaller than the second average value threshold and the reference signal received power of the wireless communication cell is smaller than the second power threshold, no processing is performed.
In the above embodiment, the reprioritization refers to a priority of each wireless communication cell selected for the terminal to access after the wireless communication cells satisfy the reselection condition. The reselection condition refers to a screening condition that the wireless communication cell needs to satisfy when the wireless communication cell to which the terminal is connected is selected, and in the embodiment of the present application, the higher the reprioritization is, the higher the probability of being selected as the cell to which the terminal accesses is.
In some embodiments herein, the first average threshold value is greater than or equal to 10 and less than or equal to 31; the value of the second average threshold is greater than or equal to 0 and less than or equal to 7; the second power threshold ranges from-110 dBm to-115 dBm.
For example, the value of the first average threshold is 12, the value of the second average threshold is 7, and the value of the second power threshold is-115 dBm, based on which, the parameter values of the signal environment parameters in different value ranges correspond to different network scheduling processes, which specifically includes:
when the average value of the channel quality indicators is greater than 12, the corresponding network scheduling process is as follows: reducing the reference signal receiving power reported to the base station so that the base station controls the terminal to switch the wireless network cell;
when the average value of the channel quality indications is less than 7 and the reference signal received power of the wireless network cell is greater than-115 dBm, the corresponding network scheduling processing is as follows: disconnecting the network connection with the wireless network cell and reducing the reselection priority of the wireless network cell so that the base station sends switching information to the terminal and the control terminal switches the accessed wireless network cell according to the switching information;
if the average value of the channel quality indicators is less than 7 and the reference signal received power of the wireless communication cell is less than-115 dBm, no processing is performed.
In some embodiments in the present application, the rate threshold may be selected according to actual usage needs, for example, 640kbps (80 kB/s) is selected, that is, when the downlink average rate is less than or equal to 640kbps, it is considered that the downlink congestion exists in the wireless network cell to which the terminal is accessed.
In some embodiments in the application, the signal environment parameter includes a downlink average rate as described above, and it can be understood that the signal environment parameter is obtained once every period, and then downlink congestion is identified according to the downlink average rate in the signal environment parameter, and when it is detected that the downlink average rate is less than or equal to a rate threshold, it is considered that downlink congestion exists in a wireless network cell to which the terminal is accessed.
In the embodiment of the application, a set of downlink congestion detection and recovery flow is established, and the downlink congestion and downlink scheduling abnormity are automatically identified and corresponding network scheduling processing is triggered to escape from the current wireless communication cell in time, so that the network environment of the terminal is improved, and the active recovery capability of the terminal in coping with the abnormal network environment is improved.
Specifically, the downlink average rate of the wireless network cell to which the terminal is accessed is monitored, so that the downlink congestion and the downlink scheduling abnormality of the wireless network cell to which the terminal is accessed are identified according to the magnitude relation between the downlink average rate and the rate threshold. Specifically, under the condition that the downlink average rate is less than or equal to the rate threshold, it is considered that the wireless network cell to which the terminal is accessed has downlink congestion and downlink scheduling abnormality, at this time, the corresponding network scheduling processing is selected according to the parameter value of the signal environment parameter of the wireless network cell, so that after the network scheduling processing is performed, the current wireless communication cell is escaped, and then the wireless communication cell is accessed to other wireless communication cells, thereby improving the network environment of the terminal, such as improving the fluency of communication and internet access.
Under the condition that a terminal is accessed to a wireless communication cell under an independent networking (SA) network environment, the embodiment of the application can timely identify a traffic jam scene and trigger corresponding optimization measures for conversation and surfing the Internet caused by SA network abnormality, so that the current abnormal wireless communication cell is timely escaped, an abnormal network environment, namely the wireless communication cell, is avoided, and the communication surfing experience of a terminal user under the SA network is greatly improved.
In some embodiments in the present application, the signal environment parameters may include, for example: the cell RSRP, the RSRQ mean value, the downlink average rate and the CQI mean value in the CSI reported by the terminal.
Wherein, reference Signal Receiving Power (RSRP) is a linear average of received Power (in watts) on a Resource Element (RE) carrying a Reference Signal over a measurement frequency bandwidth.
Here, the LTE (Long Term Evolution of the general mobile communication technology) Reference Signal Received Quality (RSRQ) is based on which the RSRQ mean can be understood as the mean of the LTE Reference Signal received Quality, where the RSRQ is defined as the ratio of N × RSRP/(LTE carrier RSSI), where N is the number of Resource Blocks (RBs) of the LTE carrier RSSI measurement bandwidth.
Among them, channel State Information (CSI), in the field of wireless communication, so-called CSI, is a Channel property of a communication link. It describes the fading factor of the signal on each transmission path, i.e. the value of each element in the channel gain matrix H, such as signal Scattering (Scattering), environmental fading (fading), distance fading (power fading) and other information. The CSI may adapt the communication system to the current channel conditions, providing a guarantee for high reliability and high rate communication in a multi-antenna system.
The CQI is an information Indicator of Channel Quality, which represents the Quality of the current Channel, and the value range of the CQI is 0 to 31 corresponding to the signal-to-noise ratio of the Channel, based on which the CQI mean value can be understood as the average value of the Channel Quality Indicator.
In some embodiments herein, the signal environment parameter comprises an average value of the channel quality indication; according to the parameter value of the signal environment parameter of the wireless network cell, network scheduling processing is carried out, and the method comprises the following steps:
and under the condition that the average value of the channel quality indications is greater than the first average value threshold value, reducing the reference signal receiving power reported to the base station so that the base station controls the terminal to switch into the accessed wireless network cell.
Specifically, as shown in fig. 2, in step 104, performing network scheduling processing according to a parameter value of a signal environment parameter of a wireless network cell includes:
and step 204, reducing the reference signal receiving power reported to the base station.
In this embodiment, when the average value of the channel quality indicators is greater than the first average threshold, it is considered that the average value of the channel quality indicators reported by the terminal is higher, and at this time, the signal environment of the current wireless communication cell is better, but the downlink scheduling is weaker, for example: stations, squares and other densely populated areas.
The reference signal receiving power reported by the terminal to the base station is reduced, so that the base station connected with the terminal can redistribute the cell connected with the terminal according to the reported reference signal receiving power, and the current wireless network cell accessed by the terminal is switched to other wireless network cells, thereby escaping from the current wireless network cell.
In the above embodiment, the problem of downlink congestion and downlink scheduling abnormality of the current wireless network cell is solved by escaping from the current wireless network cell, so that the terminal is accessed to other wireless network cells with better downlink rate, thereby improving the network environment of the terminal.
Illustratively, the value of the first average threshold is greater than or equal to 10, and in some embodiments of the present application, the value of the first average threshold is 12.
In some embodiments of the present application, as shown in fig. 3, reducing the reference signal received power reported to the base station, so that the base station controls the wireless network cell to which the terminal is handed over to access, includes:
step 302, reporting the first reference signal receiving power to a base station, and reducing the first reference signal receiving power according to a power adjustment value to obtain a second reference signal receiving power;
and step 304, reporting the second reference signal receiving power to the base station so that the base station sends switching information to the terminal, and controlling the terminal to switch the accessed wireless network cell according to the switching information.
In the embodiment, the reference signal receiving power reported to the base station is reduced, so that the base station can utilize the existing switching mechanism to realize the switching of the wireless network cells accessed by the terminal, and the impact required by the terminal when the terminal is switched among the wireless network cells is reduced, thereby improving the stability of data communication among different wireless network cells.
In some embodiments herein, the first reference signal received power is a reference signal received power before the reduction and the second reference signal received power is a reference signal received power after the reduction.
In some embodiments herein, the second reference signal received power is equal to the first reference signal received power minus a power adjustment value.
In some embodiments of the present application, the terminal reports the received power of the reference signal to the base station every first time interval. Specifically, reporting the first reference signal receiving power to a base station, and reducing the first reference signal receiving power according to a power adjustment value to obtain a second reference signal receiving power; and reporting the second reference signal receiving power to the base station for a first time length after the first reference signal receiving power is reported to the base station, reducing the second reference signal receiving power according to the power adjustment value to obtain a third reference signal receiving power, reporting the third reference signal receiving power to the base station, and so on.
In some embodiments in the present application, the power adjustment value is 4dBm, which can be taken according to actual usage requirements, and the specific value is not described herein again.
In some embodiments in the application, the value of the first duration may be taken according to actual use requirements, and exemplarily, the value of the first duration is 2 seconds.
Exemplarily, the first reference signal received power may be 154dBm, and after 2 seconds after 154dBm is reported to the base station, 150dBm is reported to the base station; 2 seconds after reporting 150dBm to the base station, reporting 146dBm to the base station, and so on.
In some embodiments in this application, reducing the reference signal received power reported to the base station, so that the base station controls the wireless network cell to which the terminal is switched, further includes: acquiring the accumulated reduction value of all reference signal receiving power reported to a base station; and under the condition that the accumulated reduction value is greater than or equal to the first power threshold value, disconnecting the network connection with the wireless network cell, and reducing the reselection priority of the wireless network cell so that the base station sends switching information to the terminal, and the terminal is controlled to switch the accessed wireless network cell according to the switching information. As can be seen from the above, by setting the first power threshold, the accumulated reduction value of the reported reference signal received power is greater than or equal to the first power threshold as a condition for disconnecting the network connection with the wireless network cell, the base station is enabled to issue the switching information to the terminal in an active disconnection manner of the terminal, the terminal is controlled to switch the accessed wireless network cell according to the switching information, active switching of the wireless network cell is realized, and the influence on the use of a terminal user caused by long-time access of the terminal to a wireless communication cell with congestion of a downlink channel or abnormal downlink scheduling is reduced.
Specifically, in step 204, after the reference signal received power reported to the base station is reduced, the method further includes:
and step 210, disconnecting the network connection with the wireless network cell, and reducing the reselection priority of the wireless network cell, so that the base station sends switching information to the terminal, and the control terminal switches the accessed wireless network cell according to the switching information.
In some embodiments of the present application, the handover information is determined based on reselection priorities of wireless network cells, specifically, each of the multiple candidate wireless network cells of the base station has a reselection priority, and the wireless network cell after handover is selected according to the reselection priority of each of the multiple candidate wireless network cells, so that the terminal performs handover.
Specifically, the handover information includes a name or an identification of a wireless network cell to which the terminal needs to access.
In some embodiments herein, the first power threshold is greater than the power adjustment value.
In some embodiments of the present application, the accumulated reduction value is an accumulated value of the power adjustment value during the first reference signal received power reduction process.
In some embodiments herein, the signal environment parameters include an average value of the channel quality indication and a reference signal received power of the wireless network cell; according to the parameter value of the signal environment parameter of the wireless network cell, network scheduling processing is carried out, and the method comprises the following steps: and under the condition that the average value of the channel quality indications is smaller than the second average value threshold and the reference signal receiving power of the wireless network cell is larger than the second power threshold, disconnecting the network connection with the wireless network cell and reducing the reselection priority of the wireless network cell so that the base station sends switching information to the terminal and the terminal is controlled to switch the accessed wireless network cell according to the switching information.
In this embodiment, the average value of the channel quality indicator and the reference signal received power are selected as parameters used in downlink congestion optimization, and when the average value of the channel quality indicator is smaller than the second average threshold and the reference signal received power of the wireless network cell is greater than the second power threshold, it is considered that the current downlink congestion is caused by strong signal interference of the wireless network cell, but since the reference signal received power of the wireless network cell is greater than the second power threshold, that is, the reference signal received power is strong, cell handover cannot be performed, and the terminal always resides in the current second power threshold. Such as: in the scenarios such as the cell scenario interfered by the neighboring cell, the signal interference received by the terminal at this time is slightly strong, which results in poor downlink scheduling of the terminal.
By disconnecting the network connection with the wireless network cell, the wireless communication cell connection accessed by the base station reselect the terminal is forcibly realized, the terminal is prevented from being accessed into the wireless communication cell with congestion of a downlink channel or abnormal downlink scheduling for a long time, and the use experience of a terminal user is improved.
In some embodiments in the present application, the disconnecting of the network connection with the wireless network cell and the lowering of the reselection priority of the wireless network cell may be performed simultaneously or sequentially, and specifically, in the case of performing sequentially, after detecting that the network connection with the wireless network cell is disconnected, the lowering of the reselection priority of the wireless network cell is performed, and the current wireless communication cell is escaped from the current wireless communication cell and then is accessed to another wireless communication cell, so as to improve the network environment of the terminal.
In some embodiments in the present application, the second power threshold value is between-110 dBm and-115 dBm, such as-115 dBm, and the specific value thereof may be selected according to actual usage requirements, which is not described herein again.
In some embodiments in the application, a value of the second average threshold is less than or equal to 7, exemplarily, the value of the second average threshold is 7, and a specific value thereof may be selected according to actual use needs, which is not described herein again.
In some embodiments in the present application, reducing the reselection priority of the wireless network cell specifically includes:
acquiring the current reselection priority of the wireless network cell; adjusting the current reselection priority to obtain an adjusted reselection priority, wherein the adjusted reselection priority is lower than the reselection priority before adjustment, and maintaining a preset time of the adjusted reselection priority, wherein a value of the preset time may be 10 minutes, 20 minutes, and the like, and a value may be taken according to actual use needs, which is not described herein again.
In some embodiments of the present application, in a case that the average value of the channel quality indicator is smaller than the second average value threshold and the reference signal received power of the wireless communication cell is smaller than the second power threshold, the overall signal environment of the wireless communication cell is poor, for example, a terminal at a cell edge, and downlink scheduling of the cell is weak to an expected extent, at this time, no processing is performed.

Specifically, reporting the first reference signal receiving power to a base station, and reducing the first reference signal receiving power according to a power adjustment value to obtain a second reference signal receiving power; and reporting the second reference signal receiving power to the base station for a first time length after the first reference signal receiving power is reported to the base station, reducing the second reference signal receiving power according to the power adjustment value to obtain a third reference signal receiving power, reporting the third reference signal receiving power to the base station, and so on.
In some embodiments of the present application, the processing module 404 is further configured to obtain an accumulated reduction value of the received power of all reference signals reported to the base station; and under the condition that the accumulated reduction value is greater than or equal to the first power threshold value, disconnecting the network connection with the wireless network cell, and reducing the reselection priority of the wireless network cell so that the base station sends switching information to the terminal, and the terminal is controlled to switch the accessed wireless network cell according to the switching information.
As can be seen from the above, by setting the first power threshold, the accumulated reduction value of the reported reference signal received power is greater than or equal to the first power threshold as a condition for disconnecting the network connection with the wireless network cell, the base station is enabled to issue the switching information to the terminal in an active disconnection manner of the terminal, the terminal is controlled to switch the accessed wireless network cell according to the switching information, active switching of the wireless network cell is realized, and the influence on the use of a terminal user caused by long-time access of the terminal to a wireless communication cell with congestion of a downlink channel or abnormal downlink scheduling is reduced.
In some embodiments of the present application, the handover information is determined based on reselection priorities of wireless network cells, specifically, each of the multiple candidate wireless network cells of the base station has a reselection priority, and the wireless network cell after handover is selected according to the reselection priority of each of the multiple candidate wireless network cells, so that the terminal performs handover.
Specifically, the handover information includes a name or an identification of a wireless network cell to which the terminal needs to access.
In some embodiments herein, the first power threshold is greater than the power adjustment value.
In some embodiments herein, the signal environment parameters include an average value of the channel quality indication and a reference signal received power of the wireless network cell; the processing module 404 is further configured to disconnect a network connection with the wireless network cell and reduce a reselection priority of the wireless network cell under the condition that the average value of the channel quality indications is smaller than the second average value threshold and the reference signal received power of the wireless network cell is greater than the second power threshold, so that the base station sends the switching information to the terminal, and the terminal is controlled to switch the accessed wireless network cell according to the switching information.
In this embodiment, the average value of the channel quality indicator and the reference signal received power are selected as parameters used in downlink congestion optimization, and when the average value of the channel quality indicator is smaller than the second average threshold and the reference signal received power of the wireless network cell is greater than the second power threshold, it is considered that the current downlink congestion is caused by stronger signal interference of the wireless network cell, but because the reference signal received power of the wireless network cell is greater than the second power threshold, that is, the reference signal received power is stronger, cell handover cannot be performed, and thus the terminal always resides in the current second power threshold. Such as: in the scenarios such as the cell scenario interfered by the neighboring cell, the signal interference received by the terminal at this time is slightly strong, which results in poor downlink scheduling of the terminal.
By disconnecting the network connection with the wireless network cell, the method can forcibly make the base station reselect the wireless communication cell to which the terminal is accessed, thereby reducing the influence of the terminal user on the use of the terminal due to the fact that the terminal is accessed in the wireless communication cell with congestion of a downlink channel or abnormal downlink scheduling for a long time.
In some embodiments in the present application, disconnecting the network connection with the wireless network cell and reducing the reselection priority of the wireless network cell may be performed simultaneously or sequentially, and specifically, in the case of performing sequentially, after detecting that the network connection with the wireless network cell is disconnected, the reselection priority of the wireless network cell is reduced.
In some embodiments in the present application, reducing the reselection priority of the wireless network cell specifically includes:
acquiring the current reselection priority of the wireless network cell; and adjusting the current reselection priority to obtain an adjusted reselection priority, wherein the adjusted reselection priority is lower than the reselection priority before adjustment, and maintaining a preset time length of the adjusted reselection priority, wherein the value of the preset time length may be 10 minutes, 20 minutes, and the like, and the value may be taken according to actual use needs, which is not described herein again.
In some embodiments of the present application, in a case that the average value of the channel quality indicator is smaller than the second average value threshold and the reference signal received power of the wireless communication cell is smaller than the second power threshold, the overall signal environment of the wireless communication cell is poor, for example, a terminal at a cell edge, and downlink scheduling of the cell is weak to an expected extent, at this time, no processing is performed.
