In the description of the present application, "/" means "or" unless otherwise indicated, for example, A/B may mean A or B. "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. Further, "at least one", "a plurality" means two or more. The terms "first," "second," and the like do not limit the number and order of execution, and the terms "first," "second," and the like do not necessarily differ.
Currently, in the radio resource scheduling technology, the implementation is mainly realized through priority calculation, MCS selection and resource allocation. The priority calculation generally refers to determining, by a scheduler (i.e., a radio resource scheduler), a scheduling priority of a terminal carried by a cell according to information (such as overall signal strength, signal quality, and current remaining resource information of the cell) input by scheduling, and performing resource scheduling on the user; the MCS generally refers to determining the MCS of each scheduling user according to the information input by the scheduling, and adopting different channel coding efficiency under different modulation modes, so as to provide a high-order modulation mode and a high coding efficiency for a scene with high channel quality (the modulation order and the coding efficiency are in direct proportion to the transmission efficiency of data); the resource allocation generally refers to a time slot (slot) where a User Equipment (UE) is scheduled by a scheduler, and an orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol scheduled in the slot actually refers to, and determines the number of Resource Blocks (RBs) and RB positions allocated to the User according to data amount information of the User and a selected MCS.
However, in the above method, in the scheduling process, the scheduling of radio resources is mainly implemented based on the current overall network situation of the cell, and the result of the radio resource scheduling cannot be perceived to be close to the use of the user. If the wireless resources possibly allocated to the users with more frequent use of the partial network cannot meet the use requirement of the users, the use perception of the users is affected, and the users with less use of the partial network can be allocated with more resources, so that the resources are wasted. Therefore, the current wireless resource scheduling cannot be really close to the use perception of the user, namely, the wireless resource scheduling cannot guarantee the use perception of the user, and the rationality of the resource scheduling is poor.
The resource scheduling method provided by the embodiment of the application can be applied to a resource scheduling system. Fig. 1 shows a schematic diagram of a structure of the resource scheduling system. As shown in fig. 1, the resource scheduling system 10 includes: target terminal 11, electronic device 12, and base station 13.
The resource scheduling system 10 may be used for the internet of things, and the resource scheduling system 10 (such as the target terminal 11, the electronic device 12 and the base station 13) may include a plurality of central processing units (central processing unit, CPUs), a plurality of memories, a storage device storing a plurality of operating systems, and other hardware.
The target terminal 11 is a terminal device of a user and is configured to send alert information to the electronic device 12, so that the electronic device 12 schedules radio resources for the target terminal 11.
The electronic device 12 is configured to receive the alert information sent by the target terminal 11, and schedule a corresponding radio resource for the target terminal according to the alert information.
The base station 13 is a base station to which the target terminal 11 accesses, and is configured to provide radio resources for the target terminal 11.
Alternatively, as shown in fig. 1, the electronic device 12 may implement allocation and scheduling of radio resources of the target terminal 11 by interacting with the base station 13.
In one possible implementation, the electronic device 12 may also be integrated with the base station 13.
The following describes a resource scheduling method provided by an embodiment of the present application with reference to the accompanying drawings.
As shown in fig. 2, the resource scheduling method provided by the embodiment of the present application includes S201-S202:
s201, receiving alarm information sent by a target terminal in a target cell.
Wherein the alert information includes at least one of: the system comprises time delay alarm information and rate alarm information, wherein the time delay alarm information is used for indicating that the current network time delay of the target terminal is larger than the current time delay requirement of the target terminal, and the rate alarm information is used for indicating that the current network rate of the target terminal is smaller than the current rate requirement of the target terminal.
Optionally, in combination with fig. 1, the electronic device 12 may monitor in real time whether the target terminal 11 in the target cell sends the alarm information, and receive the alarm information in time when the target terminal 11 sends the alarm information.
Optionally, the current network delay of the target terminal is greater than the current delay requirement of the target terminal, which can be understood that the network delay of the target terminal cannot meet the delay requirement of the current use scene of the target terminal, such as that the delay of an application program running in the target terminal is greater; the current network rate of the target terminal is smaller than the current rate requirement of the target terminal, which can be understood that the maximum throughput (or average throughput) of the network of the target terminal cannot meet the time delay requirement of the current use scene of the target terminal, for example, the network rate of the target terminal is lower.
The method includes the steps that when a game application running in a target terminal is blocked for a plurality of times and high delay occurs, the target terminal sends a delay alarm; and when the audio and video application program running in the target terminal or the application program is downloaded or updated, the target terminal sends rate alarm information when the clamping occurs for a plurality of times.
The audio/video application refers to a non-real-time communication application (i.e., an application with low real-time requirements for resources) installed in the target terminal and used for playing audio, video, and the like.
In one possible implementation manner, the application program in the target terminal may be adjusted, or a preset application program for monitoring the network condition may be installed in the target terminal, so that the application program in the target terminal or the preset application program may automatically send the corresponding alarm information when the network condition fails to meet the use requirement of the application program itself.
For example, taking a preset application program for monitoring network conditions as an example, when the target terminal runs an audio-video application program and a plurality of pauses occur, the preset application program can determine that the current network rate of the target terminal is smaller than the current rate requirement of the target terminal, and send rate alarm information.
For example, taking an example that an application program automatically sends alarm information, a certain video playing software on a target terminal continuously clips a video imitation screen due to low obtained network rate. At this time, the video playing software can send out a rate-increasing demand warning to the target terminal, and when the target terminal receives the rate-increasing demand warning, the target terminal sends rate warning information to the target cell (i.e. the main service cell to which the target terminal is currently connected).
S202, determining the network demand of the target terminal based on the alarm information, and adjusting the network parameters corresponding to the target terminal.
Wherein the network demand includes at least one of: network delay is reduced, and network rate is increased.
It can be understood that when the alarm information sent by the target terminal is time delay alarm information, determining the network requirement of the target terminal as reducing the network time delay; when the alarm information sent by the target terminal is rate alarm information, determining the network requirement of the target terminal as improving the network rate.
Optionally, based on specific network requirements of the target terminal, network parameters corresponding to the network requirements can be adjusted.
Specifically, when the network requirement of the target terminal is to reduce the network delay, the network delay parameters corresponding to the target terminal can be adjusted to reduce the network delay of the target terminal; when the network requirement of the target terminal is to increase the network rate, the network rate class parameter corresponding to the target terminal can be adjusted.
It should be noted that, the present application is mainly applied to adjusting the radio resource scheduling after completing the radio resource of the target cell; or in a scenario where radio resource assisted scheduling of the target cell is implemented.
Optionally, when it is determined that the target terminal has multiple network requirements, if the target terminal has both a requirement for reducing network delay and a requirement for increasing network rate, then simultaneously adjusting the network parameters of the target terminal for reducing network delay and the network parameters for increasing network rate.
In the embodiment of the application, when the wireless resource is scheduled, delay alarm information and/or rate alarm information sent by the target terminal in the target cell are received, and according to the delay alarm information and/or the rate alarm information, whether the current network delay of the target terminal is greater than the current delay requirement of the target terminal or whether the current network rate of the target terminal is less than the current rate requirement of the target terminal is determined, so that the network parameters corresponding to the target terminal are adjusted. According to the method, based on the specific use perception of the target terminal, the network parameters corresponding to the target terminal can be adjusted, personalized scheduling of the wireless resources is achieved, scheduling of the wireless resources is enabled to be close to the use perception of the user (terminal), and the rationality of scheduling of the wireless resources is improved.
In a possible implementation manner, as shown in fig. 3, in a resource scheduling method provided by an embodiment of the present application, the "adjusting a network parameter corresponding to a target terminal" in S202 includes S301 to S302:
and S301, when the network requirement of the target terminal is determined to be the network delay reduction, the network delay corresponding to the target terminal is reduced.
And S302, when the network requirement of the target terminal is determined to be the network rate improvement, the network rate corresponding to the target terminal is improved.
Optionally, the network delay corresponding to the target terminal may be understood as a transmission waiting delay of a network resource allocated to the target terminal by the base station; the network rate corresponding to the target terminal can be understood as the network resource size of the target terminal through the base station.
Optionally, when determining the network demand type of the target terminal, the relevant parameters of the resource scheduling of the target terminal can be adjusted by combining the network demand type and the service experience, so as to realize the network demand of the target terminal, i.e. reduce the network delay corresponding to the target terminal or improve the network rate corresponding to the target terminal.
In one possible implementation manner, the network requirement of the target terminal can also be achieved by adjusting physical state information such as a base station to which the target terminal is connected.
For example, when the network requirement of the target terminal is determined to reduce the network delay, the base station to which the target terminal is currently connected may be changed to the base station closest to the target, so as to reduce the network delay of the target terminal.
In the embodiment of the application, the corresponding wireless resources are scheduled for the target terminal according to different network demand types of the target terminal by determining the network demand type of the target terminal, so that the accuracy of wireless resource scheduling is improved, and the scheduling of the wireless resources is further close to the use perception of users.
In a possible implementation manner, as shown in fig. 4, in a resource scheduling method provided in an embodiment of the present application, S301 includes S401 to S402:
s401, when the network requirement of the target terminal is determined to be network reduction, the delay is delayed, and the average network delay corresponding to the target terminal in the first historical time period is determined.
The average network time delay is used for indicating the average duration of network resource allocation for the target terminal in the first historical time period.
Alternatively, the first historical time period may be determined in connection with a particular need, e.g., the first historical time period may be the first 10 minutes, the first 20 minutes, etc.
For example, when the application program of the target terminal sends a resource allocation request to the network side (cell base station) for 60ms and the network side responds to the resource allocation request and allocates resources to the target terminal for 50ms, the network delay can be determined to be 110ms.
Optionally, the average network delay of the target terminal in the first historical period may be determined according to the network delay corresponding to the resource allocation request sent by the target terminal in the first historical period.
S402, determining the duration of the average network delay reduced by the preset step length as the network delay corresponding to the target terminal.
Optionally, the preset step length may be determined in conjunction with a specific service requirement, e.g., the preset step length may be 1ms, 5ms, etc.
Optionally, when the network delay is adjusted for the target terminal, a monitoring period may be set for the target terminal, whether the target terminal still sends the delay warning information is continuously monitored in the monitoring period, and when the target terminal still sends the delay warning information, the network delay corresponding to the target terminal is adjusted for the target terminal again until the target terminal does not send the delay warning information any more.
For example, whether the target terminal transmits the delay warning information may be continuously monitored through the cell in the monitoring period.
It should be noted that, the network delay corresponding to the target terminal may be understood as a priority of scheduling the radio resource for the target terminal, that is, when the target terminal sends delay alarm information, the scheduling priority of the target terminal is adjusted in the radio resource transmission process, so as to schedule the radio resource for the target terminal as soon as possible, thereby reducing delay perception of the target terminal.
In the embodiment of the application, the average network delay of the target terminal in the historical time period is determined, and the network delay corresponding to the target terminal is adjusted by taking the average network delay as a reference, so that when the use of the target terminal is perceived as high in network delay, the network delay of the target terminal can be accurately reduced, and further, the scheduling of the wireless resource can be obviously perceived by the target terminal, so that the accuracy of the scheduling of the wireless resource is improved.
In a possible implementation manner, as shown in fig. 5, in a resource scheduling method provided by an embodiment of the present application, S302 includes S501 to S503:
s501, when the network requirement of the target terminal is determined to be the improvement of the network rate, the allocation information of all network resources in the target cell is determined.
It should be noted that determining allocation information of all network resources in the target cell may be understood as determining allocation conditions of all network resources in the target cell, such as whether there are spare network resources in the target cell (i.e. whether there are unallocated network resources), and information such as allocation amounts of network resources of all terminal devices in the target cell.
Optionally, the network resources, that is, the resources required by the target terminal to implement the network service function, such as multiple resources including frequency resources, time resources, code domain resources, space resources, power resources, and the like, and the network resources involved in specific resource scheduling need to be determined in combination with specific service requirements.
Illustratively, all network resources in the target cell may be all time-frequency resources in the target cell.
S502, when it is determined that unallocated network resources exist in the target cell, allocating the network resources of the first preset resource amount to the target terminal.
It should be noted that there are unassigned network resources in the target cell, and it is understood that there are network resources which are unassigned to the target terminal and can be assigned among all the network resources in the target cell.
Alternatively, the first preset resource amount may be set in combination with the network resource requirement of the target terminal (i.e. the difference between the network rate required by the target terminal and the actual network rate of the target terminal), and the resource scheduling experience.
Illustratively, the first preset amount of resources may be 1 physical resource block (physical resource blocks, PRB), 5PRB, or the like.
S503, when it is determined that unallocated network resources do not exist in the target cell, determining a first terminal which does not send rate alarm information in a second historical time period and occupies the most resources from the target cell, and allocating network resources with a second preset resource amount allocated to the first terminal to the target terminal.
It should be noted that, in one possible implementation manner, the terminal device in the target cell may have a portion of guaranteed rate terminals (users), where the network rate of the portion of terminals needs to be guaranteed preferentially, and then it is further required to determine that the first terminal is a non-guaranteed rate terminal, that is, a terminal device capable of adjusting the resource allocation amount.
Alternatively, the second historical period of time may be determined in connection with a specific business requirement, such as 5 minutes, 10 minutes, etc.
In one possible implementation manner, under the condition that unallocated network resources do not exist in the target cell, a plurality of terminal devices which do not send out rate alarm information within the previous 10 minutes can be generated, and then according to the network resources occupied by each terminal device in the plurality of terminal devices, the priority corresponding to each terminal device is determined, the more occupied network resources are, the higher the priority corresponding to the terminal devices is, and then the terminal device with the highest priority is determined to be the non-first terminal.
In another possible implementation manner, the network resource occupied by each terminal device in the target cell may be determined if there is no unallocated network resource in the target cell, and the priority corresponding to the terminal device may be determined according to the network resource occupied by each terminal device, where the priority corresponding to the terminal device with more occupied network resources is higher. Further, when the terminal device with the highest priority does not send the rate alarm information in the second historical time period, determining the terminal device with the highest priority as the first terminal; when the terminal equipment with the highest priority sends the over-rate alarm information in the second history time period, the terminal equipment with the second priority is reselected without considering the terminal equipment which sends the over-rate alarm information in the second history time period, and whether the terminal equipment with the second priority sends the over-rate alarm information in the second history time period is determined until the terminal equipment which does not send the over-rate alarm information in the second history time period is found, and the terminal equipment with the high priority is used as the first terminal.
Optionally, when the first terminal does not exist in the plurality of terminal devices in the target cell, the target terminal may not be subjected to resource scheduling, or further judgment is made by combining expert experience, so as to realize scheduling of wireless resources.
It should be noted that, the network resources of the second preset resource amount allocated to the first terminal are allocated to the target terminal, which may be understood as reducing the network resources of the second preset resource amount among the network resources allocated to the first terminal, and allocating the network resources of the second preset resource amount to the target terminal.
Alternatively, the second preset resource amount may be determined in conjunction with a specific service requirement, for example, the second resource amount may be 1PRB, 3PRB, 5PRB, etc.
Optionally, when allocating network resources to a target terminal, a monitoring period may be set for the target terminal, and whether the target terminal still sends rate alarm information is continuously monitored in the monitoring period, and when the target terminal still sends rate alarm information, network resources are allocated to the target terminal again until the target terminal does not send rate alarm information any more.
For example, whether the target terminal transmits the rate alert information may be continuously monitored by the cell during the monitoring period.
In the embodiment of the application, whether the target cell has spare network resources is determined, and then the wireless resource scheduling of the target terminal is realized according to different conditions, so that the use perception of other terminal equipment in the target cell is ensured as much as possible when the wireless resource is allocated to the target terminal, the resource scheduling of the target terminal is realized as much as possible based on the use perception conditions of all terminals in the target cell, and the rationality of the resource scheduling is further improved.
In a possible implementation manner, as shown in fig. 6, in a resource scheduling method provided by an embodiment of the present application, S601 is further included:
and S601, when the number of times of sending the alarm information by the target terminal in the preset period is greater than a preset threshold value, the network parameters corresponding to the target terminal are not regulated in the target duration.
Optionally, the number of times the target terminal transmits the alarm information in the preset period may be understood as the number of times the alarm information transmitted by the target terminal is received and processed in the preset period.
It should be noted that, in connection with fig. 1, in the process of scheduling the resources of the target terminal 11, the use awareness of other terminals in the target cell may be affected by frequently processing the alarm information of the target terminal 11 (i.e. frequently allocating network resources to the target terminal 11) due to the problem of the target terminal 11 itself (such as the failure of the related module), the problem of the electronic device 12 (such as the failure of the related module), and/or the problem of the base station 13 (such as the failure of the related module), so that for this case, timely processing is required to prevent the use awareness of other users in the target cell from being affected.
Optionally, when the number of times of sending the alarm information by the target terminal in the preset period is greater than a preset threshold, the alarm information can be sent through the electronic equipment, and a professional technician confirms whether the equipment fails or not and performs corresponding processing.
For example, when the professional technician confirms that the equipment has no problem, parameters such as a preset period, a preset threshold value and/or a target duration can be adjusted to prevent frequent false alarm of the alarm information; when the professional technician confirms that the equipment has a problem, the maintenance and obstacle removal are performed on the related equipment.
Optionally, for the preset period, the preset threshold value and the target duration, the service experience and the specific service scene (such as the quality of the cell network) can be combined for determination.
For example, the preset period may be 30 minutes, the preset threshold may be 10 times, and the target time period may be 2 hours. That is, when the number of times that the target terminal transmits the alarm information within 30 minutes is greater than 10 times, the network parameters corresponding to the target terminal are not adjusted within 2 hours.
Optionally, for different alarm information (such as delay alarm information and rate alarm information), different preset periods, preset thresholds and/or target durations may be set, or the same preset periods, preset thresholds and/or target durations may be set, which may be specifically determined in conjunction with service requirements.
Optionally, the network parameters corresponding to the target terminal are not adjusted within the target duration, which can be understood as not receiving the alarm information sent by the target terminal, or not performing corresponding processing according to the alarm information sent by the target terminal.
In the embodiment of the application, when the target terminal frequently sends the alarm information, the related network parameters are not regulated for the target terminal any more, so that the problem that network resources are frequently scheduled for the target terminal due to false alarm of the alarm information by the target terminal, network perception of other terminal equipment is influenced, and the accuracy of resource scheduling is ensured.
In a possible implementation manner, in the resource scheduling method provided by the embodiment of the application, the alarm information is the alarm information sent by the target terminal when determining that the time delay of the target application program for transmitting data is greater than the first time delay; or, the alarm information is rate alarm information sent by the target terminal when the target terminal determines that the transmission rate of the data transmitted by the target application program is smaller than the first rate.
It should be noted that, for the first delay and the first rate, the determination may be performed in conjunction with a specific application according to a specific service requirement.
Illustratively, for reading category target applications, the corresponding first rate is less than for video category target applications.
Optionally, in order to ensure stability of data, an alarm period may be set, and when an average delay of data transmission of the target application program in the alarm period is greater than the first delay, or an average rate of data transmission of the target application program in the alarm period is less than the first rate, corresponding alarm information is sent through the target terminal.
Alternatively, the alarm period of the average delay and the alarm period of the average rate may be the same period or may be different periods, which may be specifically determined in combination with the service requirement.
