Referring to fig. 1, fig. 1 is a block diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a data transmitting device 11 and a data receiving device 12.

Wherein, the data transmitting device 11 and the data receiving device 12 can communicate with each other. The data transmission apparatus 11 transmits Ciphertext information (Ciphertext Block) to the data reception apparatus 12.

The network side device may be a base station, an Access and Mobility Management Function (AMF), a relay, an Access point, or other network elements.

The following describes a network optimization method provided by an embodiment of the present invention.

Referring to fig. 2, fig. 2 is a schematic flowchart of a network optimization method according to an embodiment of the present invention. The network optimization method shown in fig. 2 may be performed by a terminal.

As shown in fig. 2, the network optimization method may include the following steps:

step 301, receiving an indication message sent by a network device, where the indication message includes network state information between a terminal and the network device and scheduling time information of the terminal.

It should be noted that, when performing a multimedia service, the terminal needs to notify the network device in a Radio Resource Control (RRC) signaling manner, and apply for network state information and scheduling time information from the network device to obtain an indication message sent by the network device, where the network device is also referred to as a network side device.

The network state information between the terminal and the network device mainly includes a network busy state, that is, a network idle state and a network busy state, and mainly includes a network idle state in which the terminal transmits to the network device, a network busy state in which the terminal transmits to the network device, a network idle state in which the network device transmits to the terminal, and a network busy state in which the network device transmits to the terminal. The scheduling time information of the terminal mainly comprises the next schedulable time of the terminal, and the next schedulable time of the terminal can also be represented by the next scheduling waiting time of the terminal. The terminal may receive the network status information and the scheduling time information transmitted by the network device.

Step 302, according to the network state information and the scheduling time information, performing a service adjustment operation on the multimedia service of the terminal.

The multimedia services mainly include video network services, audio network services, and the like. The multimedia service has a large demand on network optimization of uplink and downlink large bandwidths, and taking a video network service as an example, the video service is mainly divided into a live video monitoring class, a live interaction class and a video watching class, wherein an acquisition end of the live video monitoring class mainly has the uplink large bandwidth, and a playing end mainly has the downlink large bandwidth; the acquisition end and the playing end of the live broadcast interaction have uplink and downlink large bandwidth services; the video watching service is mainly a downlink large-bandwidth service. Therefore, the network requirements of the uplink and downlink bandwidths corresponding to different multimedia service types are different.

And according to the received network state information and the scheduling time information, performing service adjustment operation on the multimedia service of the terminal. For example, in video network services, when the network state information is in a network idle state, more network available resources are available, and the user experience can be improved by improving the resolution; correspondingly, when the network state information is in a network idle and busy state, the available resources of the network are less, and the video blocking caused by network congestion can be reduced by reducing the resolution.

In addition, different service adjustment operations can be adopted for the uplink network and the downlink network, for example, under the condition that the average rate of the uplink network is greater than the bandwidth required by the current multimedia service, the adjustment operation related to the requirement of increasing the bandwidth of the uplink network of the multimedia service can be executed on the terminal; under the condition that the average rate of the downlink network is greater than the bandwidth required by the current multimedia service, the terminal can send an application for executing adjustment operation related to the requirement of improving the downlink network bandwidth of the multimedia service to the service server. Therefore, according to the network state information and the scheduling time information, the service adjustment operation can be executed on the multimedia service of the terminal through the cooperation between the terminal and the network equipment, so that the effect of network optimization is improved.

In an optional embodiment, the service transmission adjustment operation includes at least one of the following:

adjusting the resolution of the multimedia service;

sending a first request for adjusting the resolution of the multimedia service to a service server;

sending a second request to the network device to adjust the scheduling priority.

The resolution of the video service is mainly the display resolution, which means the number of pixels that can be displayed by the display, and the more pixels that can be displayed by the display, the higher the resolution, the finer the picture. The higher the resolution, the higher the network bandwidth requirements. Therefore, in an uplink network in which the terminal transmits to the network device, the resolution of the video service can be reduced and video blocking can be reduced under the condition of poor network speed or less network resource allocation.

In a downlink network transmitted from a network device to a terminal, the adjustment of multimedia service transmission is mainly realized by the terminal sending a first request for adjusting resolution to a service server, wherein the first request mainly comprises a request for improving resolution and a request for reducing resolution. Further, the service server sends the first request to the network device to adjust the resolution. For example, in a downlink network in which the network device transmits to the terminal, the resolution of the video service may be reduced, video blocking may be reduced, and the user may have better experience in the case of a poor network speed or less network resource allocation.

Additionally, a second request to adjust a scheduling priority, which may include primarily a Class index (QCI) rating, may be sent to the network device when the network state information indicates that the network is busy. The second request mainly comprises a request for improving the scheduling priority of the user. Generally, users with high scheduling priorities have higher network speeds and more network resource allocations than users with low scheduling priorities. When the network is in a busy state, the terminal can prompt a user to achieve a better playing effect of the multimedia service by improving the scheduling priority of the user, and under the condition that the user selects to improve the scheduling priority and purchases a scheduling priority improving service, the terminal can send an RRC signaling to the network equipment to apply for descending improvement of the QCI level. Meanwhile, a reasonable payment mode can be set according to the time length, for example, different price intervals are customized according to hours, days, months and years, and the requirements of users are flexibly met.

In the embodiment of the invention, the service transmission adjustment operation comprises at least one of adjusting the resolution of the multimedia service, sending a first request for adjusting the resolution of the multimedia service to a service server and sending a second request for adjusting the scheduling priority to a network device. By adjusting the resolution of the multimedia service, the uplink network can be optimized; the downlink network can be optimized by sending a first request for adjusting the resolution of the multimedia service to the service server; and sending a second request for adjusting the scheduling priority to the network equipment, and optimizing the network according to the scheduling priority signed by the user. Therefore, different network optimization modes can be adopted according to the uplink network, the downlink network and the scheduling priority signed by the user, the network optimization is comprehensive, and the effect of the network optimization can be improved.

Optionally, the adjusting the resolution of the multimedia service includes:

under the condition that the network use state is matched with a first preset requirement, the resolution of the multimedia service is improved;

reducing the resolution of the multimedia service under the condition that the network use state is matched with a second preset requirement;

the first preset requirement is that the terminal receives the network state information indicating that the network is in an idle state for M times continuously within a first pre-estimated time, the schedulable percentage is greater than a first threshold, and the average rate of data transmission from the terminal to the network equipment is greater than or equal to the transmission requirement of the multimedia service, wherein M is an integer greater than 1;

the second preset requirement comprises that the terminal receives the network state information indicating that the network is in a busy state for N times continuously within the first estimated time, the scheduling percentage is larger than a second threshold value, and the average rate of data transmission from the terminal to the network equipment is smaller than at least one item of transmission requirements of the multimedia service, wherein N is an integer larger than 1.

Wherein M and the first estimated time may be preconfigured based on empirical values. In addition, the first threshold is a preset requirement of the schedulable percentage of the uplink network, and can also be configured in advance according to an empirical value, and the schedulable percentage of the network can be calculated according to the scheduling time information of the terminal within the first estimated time. For example, when the first estimated time is 1 second, the value of M is 3, and the first threshold is 60%, the first preset requirement is that the terminal receives the network state information indicating that the network is in an idle state for 3 consecutive times within 1 second, the schedulable percentage is greater than 60%, and the average rate of data transmission from the terminal to the network device is greater than or equal to the transmission requirement of the multimedia service. The value of M is larger than 1, so that the adjustment of the resolution of the multimedia service when the network is in an idle state by accident can be avoided.

Correspondingly, N may also be preconfigured based on empirical values, and N may be equal to M. The second threshold is a preset requirement of the uplink network non-scheduling percentage, and can also be configured in advance according to an empirical value, and the non-scheduling percentage of the network can be calculated according to the scheduling time information of the terminal within the first estimated time.

In addition, the user can set a multimedia service and uplink network adaptive switch at the terminal, set a network uplink idle and busy state counter, and count the next schedulable time distribution of the uplink network within the first estimated time of the user. When the adaptive switch is opened, under the condition that the network use state is matched with the first preset requirement, the resolution of the multimedia service can be improved until the resolution is improved to the highest level, and the experience of a user in using an uplink network can be improved; if the received network state information indicates that the network is in a busy state, the network idle state count is cleared, the network busy state is recorded, and under the condition that the network use state is matched with a second preset requirement, the resolution of the multimedia service can be reduced to reduce the bandwidth requirement until the resolution is reduced to the lowest level, so that the phenomena that the multimedia service is blocked and the like when the uplink network state is congested are reduced. Thus, by adjusting the resolution, the uplink network can be optimized.

In the embodiment of the invention, under the condition that the network use state is matched with the first preset requirement, the resolution of the multimedia service is improved; and reducing the resolution of the multimedia service under the condition that the network use state is matched with the second preset requirement. Therefore, the uplink network can be optimized by adjusting the resolution, so that the experience of a user using the network can be improved.

Optionally, sending a first request for adjusting the resolution of the multimedia service to a service server, where the first request includes:

under the condition that the network use state is matched with a third preset requirement, sending a request for improving the resolution of the multimedia service to the service server;

sending a request for reducing the resolution of the multimedia service to the service server under the condition that the network use state is matched with a fourth preset requirement;

the third preset requirement is that the terminal receives the network state information indicating that the network is in an idle state for J times continuously in the second pre-estimated time, the schedulable percentage in the second pre-estimated time is greater than a third threshold, and the average rate of data transmission from the network equipment to the terminal is greater than or equal to the transmission requirement of the multimedia service, wherein J is an integer greater than 1;

the fourth preset requirement comprises that the terminal receives the network state information indicating that the network is in a busy state for K times continuously within the second pre-estimated time, the scheduling failure percentage is greater than a fourth threshold value, and the average rate of data transmission from the network equipment to the terminal is less than at least one item of transmission requirements of the multimedia service, wherein K is an integer greater than 1.

J and the second estimated time can be configured in advance according to experience values, the value of J can be the same as M, and the second estimated time can be the same as the first time. In addition, the third threshold is a preset requirement of the schedulable percentage of the downlink network, and may also be configured in advance according to an empirical value, and the third threshold may be the same as the first threshold. And in the second estimated time, the scheduling percentage of the downlink network can be calculated according to the scheduling time information of the terminal. The value of J is larger than 1, so that the adjustment of the resolution of the multimedia service when the network is in an idle state by accident can be avoided.

Correspondingly, K can also be configured in advance according to empirical values, and the value of K can be the same as that of J. The fourth threshold is a preset requirement of the network downlink network non-scheduling percentage, and may also be preconfigured according to an empirical value, and may be the same as the second threshold. In the first estimated time, the percent of the network which cannot be scheduled can be calculated according to the scheduling time information of the terminal.

In addition, the user can set a multimedia service and downlink network adaptive switch at the terminal, set a network uplink idle and busy state counter, and count the next schedulable time distribution of the uplink network in the second estimated time of the user. When the self-adaptive switch is opened, under the condition that the network use state is matched with a third preset requirement, a request for improving the resolution of the multimedia service can be sent to the service server so as to improve the resolution of the multimedia service until the resolution is improved to the highest level, and the visual effect and the auditory effect presented to a user by the multimedia service can be improved; if the received network state information indicates that the network is in a busy state, the network idle state count is cleared, the network busy state is recorded, and under the condition that the network use state is matched with a fourth preset requirement, a request for reducing the resolution of the multimedia service can be sent to a service server, and the resolution can be reduced to the lowest level.

In the embodiment of the invention, under the condition that the network use state is matched with a third preset requirement, a request for improving the resolution of the multimedia service is sent to a service server; and sending a request for reducing the resolution of the multimedia service to the service server under the condition that the network use state is matched with the fourth preset requirement. Therefore, the downlink network can be optimized by adjusting the resolution, so that the experience of a user in using the network can be improved.

Optionally, sending a second request for adjusting the scheduling priority to the network device includes:

and sending a request for improving the scheduling priority to the network equipment under the condition that the network state information indicates that the network is in a busy state.

In the uplink network, if the network state information indicates that the network is in a busy state, the user can be prompted to upgrade the QCI level, the user selects to upgrade the QCI level and pay, the terminal sends an RRC signaling to the network equipment to apply for upgrading the QCI level of the uplink network, the network equipment queries the subscription condition of the terminal after receiving the RRC signaling, sets a corresponding QCI level for the video service of the terminal, and can preferentially guarantee the service of the user. As shown in fig. 3, the network device is a fourth Generation mobile communication technology (4th-Generation,4G) base station or a fifth Generation mobile communication technology (5th-Generation,5G) base station, the 4G base station being denoted by ENB and the 5G base station being denoted by GNB. The method comprises the steps that a terminal sends a QCI level promotion application to a network device, the network device inquires about a user subscription condition after receiving the application, a core network initiates a QCI level promotion flow under the condition that the user subscription condition passes, and the network device informs the terminal that the QCI level promotion application passes; and under the condition that the user subscription condition is not passed, the core network refuses to promote the QCI level, and the network equipment informs the terminal of the refusal of the QCI level promotion application.

Correspondingly, in the downlink network, if the network state information indicates that the network is in a busy state, the user can be prompted to upgrade the QCI level, the user selects to upgrade the QCI level and pays, the terminal sends an RRC signaling to the network equipment to apply for upgrading the QCI level of the downlink network, the network equipment queries the subscription condition of the terminal after receiving the RRC signaling, sets a corresponding QCI level for the video service of the terminal, and can preferentially guarantee the service of the user.

In the embodiment of the invention, under the condition that the network state information indicates that the network is in a busy state, a request for improving the scheduling priority is sent to the network equipment. Therefore, the user can meet the network requirement of the multimedia service by improving the scheduling priority, so that the optimization effect of the network can be improved.

Referring to fig. 4, fig. 4 is a second flowchart of a network optimization method according to an embodiment of the present invention. The network optimization method of the embodiment of the invention can be executed by network equipment.

As shown in fig. 4, the network optimization method may include the following steps:

step 401, acquiring an indication message, where the indication message includes network state information between a terminal and the network device and scheduling time information of the terminal;

it should be noted that, according to the processing capability of different board hardware, the Media Access Control (MAC) scheduling module generally needs to advance by 1.5ms to 3ms for scheduling preparation, including scheduling sorting, resource allocation, and content such as Downlink Control Information (DCI). When scheduling, firstly, the schedulable users of the time slot are ordered according to a scheduling algorithm, then, the resources are allocated according to the priority level, and finally, the DCI group is carried out and the scheduling information and the corresponding data are issued.

During scheduling and sequencing, the network device may obtain network state information between the terminal and the network device, where the network state mainly includes a network idle state and a network busy state. Besides sequencing according to a scheduling algorithm, users in the scheduling queue can also estimate network resources at the same time. When the network occupies more resources, the network state is generally a busy state; when the network has occupied less resources, the network state is generally an idle state. In addition, the size of the network bandwidth occupied by the user may also affect the determination of the network status.

Step 402, sending the indication message to the terminal.

The mode of the network device sending the indication message to the terminal is mainly one of Downlink Control Information (DCI) and media access Control element (MAC CE) modes, and specifically which mode is adopted can be determined by RRC signaling interacted between the network device and the terminal.

The DCI is implemented by adding 2 fields indicating Network busy and idle information and indicating next scheduling time of the terminal to DCI information for scheduling uplink and downlink resources, for example, "Network free indicator" indicates the Network busy and idle information, and the value is 1 in an idle state of the Network and 0 in a busy state of the Network; the "UE next schedule time indicator" indicates the time that the UE needs to wait for the next scheduling, which is expressed by 2 bits.

In addition, the MAC CE mode mainly transmits the uplink and downlink busy/idle degree of the Network and the next schedulable time of the user to the terminal through a Network free indication MAC CE, and the transmission mode of the MAC CE is triggered through a periodicity mode and an event mode, and normally transmits the terminal periodically, and when the busy/idle degree of the Network changes, the MAC CE mode also needs to transmit information once to inform the terminal. For example, in the MAC CE mode, the first four bits indicate uplink and the second four bits indicate downlink through 8-bit identifiers, among the four bits, the first bit is a reserved field, the second bit indicates a network busy degree, and the third bit and the fourth bit indicate the next scheduling waiting time of the UE.

In the embodiment of the invention, the indication message comprising the network state information between the terminal and the network equipment and the scheduling time information of the terminal is obtained; further, an indication message is sent to the terminal. Therefore, the effect of network optimization can be improved through the cooperation between the terminal and the network equipment.

Optionally, the network optimization method further includes:

and receiving a second request for adjusting the scheduling priority sent by the terminal.

Wherein, the higher the scheduling priority, the better the network service enjoyed by the user. The user can select the target scheduling priority and pay for the service of the scheduling priority, the network device can inquire the network service signing condition of the terminal user after receiving the second request for adjusting the scheduling priority sent by the terminal, and the network device can set the corresponding QCI grade for the multimedia service of the terminal and can preferentially guarantee the service of the user under the condition that the user signs the network service.

In the embodiment of the invention, the network service of the user is improved by receiving the second request for adjusting the scheduling priority sent by the terminal, the service of the user can be guaranteed preferentially, and thus the effect of network optimization can be improved.

Optionally, the obtaining the network status information includes:

acquiring the number of network users and a network resource evaluation result;

obtaining a network use evaluation result according to the number of the network users and the network resource evaluation result;

under the condition that the network use evaluation result is matched with a preset requirement, acquiring a message that the network is in a busy state; or, under the condition that the network use evaluation result does not match with the preset requirement, acquiring the message that the network is in an idle state.

The network user number is the number of users in the scheduling queue, and the network resource evaluation result is an estimation result of available network resources. Generally, when the number of users in the scheduling queue is large, fewer users are using the network and more unoccupied network resources may be available.

In addition, the preset requirements mainly comprise that the number of users in the scheduling queue is larger than the preset number of users and the resource estimation is larger than the preset multiple of the bandwidth. Under the condition that the network use evaluation result is matched with any one of the condition that the number of users in the scheduling queue is larger than the preset number of users and the condition that the resource estimation is larger than the preset multiple of the bandwidth, the network can be judged to be in an idle state, and the information that the network is in the idle state can be obtained; under the condition that the network use evaluation result is not matched with two preset requirements that the number of users in the scheduling queue is larger than the user number preset value and the resource estimation is larger than the preset multiple of the bandwidth, the network can be judged to be in a busy state, and the message that the network is in the busy state is obtained.

As shown in fig. 5, the preset value of the number of users is Q, the preset multiple of the bandwidth is W, the preset requirement is that the number of users in the queue is greater than Q or the resource estimation is greater than W times of the bandwidth, the user enters the scheduling queue, and the network state can be determined to be an idle state under the condition that the number of users in the scheduling queue is greater than Q or the resource estimation is greater than W times of the bandwidth; and under the condition that the number of users in the scheduling queue is less than or equal to Q and the resource estimation is less than or equal to W times of the bandwidth, judging that the network state is a busy state.

In the embodiment of the invention, the number of network users and the network resource evaluation result are obtained; further, obtaining a network use evaluation result according to the number of network users and the network resource evaluation result; further, the busy-idle state of the network is judged according to the matching condition of the network use evaluation result and the preset requirement, and the network state information is obtained. The network state information network considers the influence of the number of users and the network resource evaluation result, so that the accuracy of the network state result can be improved.

Optionally, the obtaining the scheduling time information includes:

and acquiring the scheduling time information according to at least one of a scheduling sorting algorithm, a queuing state of adjacent time slots and a resource estimation condition.

The scheduling and sequencing algorithm is a strategy for sequencing users in a scheduling sequence, and the resource estimation condition comprises an estimation result of available network resources.

When the user still has data to be transmitted after the scheduling is completed, the scheduling time information can be obtained by evaluating the next scheduling time or the time needing to wait for scheduling of the user terminal according to the used scheduling sorting algorithm, the queuing state of the adjacent time slots and the resource estimation condition. The scheduling time parameter may be represented by y bit, for example, y may take values of 2, 3, and 4, and the value of y is not limited herein. For example, when y is 2. If no network service is needed, the value is 0; if the next same-direction time slot can be scheduled, the value is 1; if the second equidirectional time slot can be scheduled, the value is 2, and if the second equidirectional time slot can not be scheduled in the estimated range, the value is 2 ^y -1。

In the embodiment of the invention, the scheduling time information is obtained according to at least one of a scheduling sorting algorithm, a queuing state of adjacent time slots and a resource estimation condition. The scheduling time information is acquired, and a scheduling sorting algorithm, an adjacent time slot queuing state and a resource estimation condition are considered, so that the accuracy of the scheduling time information can be improved.

The various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately without conflict, and the embodiments of the present invention are not limited thereto.

For convenience of understanding, the multimedia service is exemplified as a video service as follows:

generally, the resolution of video services is 480P, and the bandwidth requirement of the network is about 1 Mbps; when the resolution of the video service is 720P, the bandwidth requirement on the network is about 2 Mbps; when the resolution of the video service is 1080P, the bandwidth requirement on the network is about 4 Mbps; when the resolution of the video service is 2K, the bandwidth requirement on the network is about 15 Mbps; when the resolution of the video service is 4K, the bandwidth requirement on the network is about 60 Mbps; when the resolution of the video service is 8K, the bandwidth requirement of the network is about 150 Mbps. It can be seen that the higher the resolution of the video-like service is, the higher the bandwidth requirement of the network is. Therefore, according to the using state of the uplink and downlink network, under the condition that the network occupies less bandwidth, the resolution of the video service can be improved, better visual experience is provided for users, and under the condition that the network occupies more bandwidth, the resolution of the video service can be reduced, so that video playing blockage is reduced. Under the conditions that the estimated time is 2 seconds, the value of M is 2, the first threshold is 60%, the average rate of data transmission from the terminal to the network device is 8Mbs, and the resolution of the video service is 720P, the method for optimizing the network mainly comprises the following steps:

firstly, a terminal applies for acquiring an indication message to a network device, wherein the indication message comprises network state information and scheduling time information.

Further, after the application instruction sent by the network device terminal, the network state information and the scheduling time information are acquired. The network state information may indicate a network idle state and a network busy state. Under the condition that the number of users in the scheduling queue is larger than the preset value of the number of users or the resource estimation is larger than the preset multiple of the bandwidth, the network state can be judged to be an idle state; and under the condition that the number of users in the queue is less than or equal to the preset number of users and the resource prediction is less than or equal to the preset multiple of the bandwidth, the network state can be judged to be a busy state. The scheduling time information mainly comprises the next scheduling time of the terminal, and the next scheduling time of the terminal can be evaluated according to the used scheduling sorting algorithm, the queuing state of adjacent time slots and the resource estimation condition.

Further, the network device sends the network status information and the scheduling time information to the terminal through the DCI information. The network state information mainly includes a network idle and busy state, specifically, a network idle state and a network busy state.

Further, the terminal obtains the use state of the network according to the network state information and the scheduling time information, and performs service adjustment operation on the multimedia service of the terminal. The judgment parameters of the use state of the network comprise the idle and busy state of the network, the schedulable percentage, the non-schedulable percentage and the average rate of uplink and downlink transmission data. Wherein the schedulable percentage and the non-schedulable percentage are determined by scheduling time information. In the scheduling time information, when the scheduling time parameter is 2, the acquired signals mainly include four types, namely 00, 01, 10 and 11, wherein a signal with a first bit being the same as a second bit is used as a signal for calculating the non-scheduling percentage, a signal with a first bit being different from the second bit is used as a signal for calculating the schedulable percentage, thus, the 00 signal and the 11 signal are used for calculating the non-scheduling percentage, the 01 signal and the 10 signal are used for calculating the schedulable percentage, and in the second estimated time, 100 signals are received in total, wherein the 00 signal is 10 times, the 01 signal is 40 times, the 10 signal is 40 times, and the 11 signal is 10 times, the non-scheduling percentage is calculated as (the number of times of the 00 signal + the number of times of the 11 signal)/the total number of times, the non-scheduling percentage is 20%, and the schedulable percentage is calculated as the number of times of the 01 signal + the number of the 10 signal)/the total number of times, the percent tunability is 80%. Then, in the uplink network, the terminal receives the network state information indicating that the network is in the idle state for 2 consecutive times within 2 seconds, the schedulable percentage of 80% is greater than 60%, and the average rate of 8Mbps for transmitting data to the network device by the terminal is greater than the transmission requirement of the video service with the resolution of 720P, and the resolution of the video service can be 1080P, so that better visual experience can be brought to the user.
