The management device #1 may determine the UE#1 to be optimized according to the performance parameters of the UE, that is, determine whether an optimization strategy needs to be created for the UE#1. Exemplarily, the management device #1 may determine whether the UE #1 is to be optimized by judging whether the performance parameter of the UE #1 satisfies the target QoE.

S303 includes the following optional steps:

S303(a): The management device #1 acquires a QoE policy. In the embodiment of the present application, the QoE policy is used to describe that the designated service of the UE in the designated area satisfies the corresponding QoE target. The management device #1 compares the indicators in the QoE policy with the obtained UE performance parameters to determine the UE#1 to be optimized and the policy #A of the UE#1.

There are two ways for management device #1 to obtain the QoE policy:

The first case is:

It should be noted that the policy applicable area, business name, and the specific indicators of the corresponding QoE target can be The operator determines it according to specific service requirements. For example, the operator determines that a specific target needs to be met to ensure that a certain entity service does not freeze during operation in a certain area; it can also be determined based on historical experience values. For example, the operator According to historical experience values, a specific target that a business needs to achieve in an effective area is estimated; it can also be a fixed standard strategy, for example, a business must achieve a specific target in a certain area under any operating conditions. As an example but not a limitation, this embodiment of the present application does not limit this.

The second case is:

Manages the locally generated QoE policy of device #1.

It should be understood that the management device #1 can automatically generate a QoE policy through the managed data, which is an example and not a limitation. For example, the management device #1 adjusts the QoE policy in real time by monitoring changes in the network status.

It should be understood that the above obtaining methods are only exemplary descriptions, which are not limited in the embodiments of the present application.

It should be understood that the management device #2 can transmit the acquired QoE policy and the acquired performance parameters of the multiple UEs to the management device #1 through the internal interface or the management device #2 transmits only the acquired performance of the multiple UEs to the management device #1 parameter, in this case management device #1 uses a locally generated QoE policy.

S303(b): The management device #1 determines the UE#1.

In this embodiment of the present application, the management device #1 may determine the UE #1 in the following manner.

The management device #1 compares the location information of multiple UEs with the policy effective area in the QoE policy, and determines that if it is the applicable area of the policy, further, the management device #1 can calculate the corresponding service based on the performance parameters of the UE. QoE, and the calculation result is compared with the QoE _Target of the corresponding service, and if the QoE _Target cannot be reached, it is determined that the UE is UE#1 that needs to be optimized.

Wherein, to determine UE#1, it is necessary to obtain the UE ID, which is used to identify UE#1. The value of the identifier is used as an example and is not limited, for example, it can be the radio network temporary identifier RNTI (Radio Network Temporary Identity) allocated by gNB or gNB (or CU-CP) id+RNTI, or 5G Globally Unique Temporary Identity 5G-GUTI (Globally Unique Temporary Identity), which is not limited in this application.

It should be noted that the management device #1 calculates the current QoE of the UE and the UE #1 determined based on the QoE, and the processing of these services can be completed by different internal function modules (and these different modules can be deployed independently to form a separate network). Meta), can also be completed by a unified function module. This application does not limit this.

S303(c): The management device #1 creates a policy #A.

In the embodiment of the present application, the management device #1 determines to modify the QOS parameters of the policy #B (an example of the second policy) of the UE #1 based on the QoE policy to obtain the policy #A. The policy #B is a policy configured by the core network device for the UE #1. In the embodiments of the present application, Priority is mainly used as an example for description. It should be noted that, as an example but not a limitation, QOS parameters such as Guaranteed Flow Bit Rate (GFBR), Maximum Flow Bit Rate (Maximum Flow Bit Rate, MFBR), etc. can all be applied to the solutions of the embodiments of the present application .

At S304, the management device #1 sends the indication information #1 to the control device #1.

The indication information #1 includes policy #A, the ID of UE #1, and applicable area information. The applicable area information is used to indicate the effective applicable area of the policy #A.

The indication information #1 may further include a monitoring execution instruction, where the monitoring execution instruction is used to instruct the control device #1 to execute policy validity protection. The execution of the policy validity protection by the control device #1 can be understood as monitoring the location of the UE#1 through the access device #1, and the access device #1 reports the location information of the UE#1 whose location has changed to the control device #1. Optionally, the monitoring execution instruction may also be carried in other messages received by the control device #1. Optionally, when the indication information #1 does not include the monitoring execution instruction, the control device #1 may also execute policy validity protection.

That is, the optimized UE#1 is in the applicable area, and the policy #A is effective. The location of UE#1 changes and leaves the applicable area, the UE no longer applies policy #A. Therefore, the UE#1 still uses the policy #A for resource configuration outside the applicable area, thereby avoiding the problem of resource waste. The applicable area of policy #A is used as an example but not a limitation, for example, cell list, Tracking Area, which is not limited in this application.

The monitoring execution instruction is used to instruct the control device #1 to perform policy validity protection, specifically monitoring the location change of UE#1 through access device #1, whether it is within the applicable area of policy #A, and once the location of UE#1 is within the applicable area of policy #A. When a change occurs, the access device #1 reports the location information of the UE#1 whose location has changed to the control device #1.

At S305, the control device #1 sends indication information #2 to the access device #1.

The indication information #2 includes the policy #A and the ID of the UE #1, and is used to instruct the access device #1 to execute the policy #A on the UE #1, that is, to modify the QOS parameters of the UE #1.

At S306, the access device #1 executes the policy #A according to the indication information #2.

The access device #1 modifies the QOS parameters of the UE #1 according to the policy #A, and re-allocates the radio resources and configures the related parameters according to the modified parameters. The method is the same as or similar to the prior art.

Based on the method shown in FIG. 3, in step S304, the indication information #1 sent by the management device #1 to the control device #1 includes the applicable area information in addition to the IDs of the policy #A and UE #1. Therefore, the management Device #1 can synchronously deliver policy #A and the applicable area of the policy to control device #1; control device #1 further determines whether the new location conforms to the applicable area information according to the location change of UE #1, thereby judging the new location Whether the policy #A is applicable, if not, the control device #1 instructs to restore the policy #B of the UE #1, and performs resource allocation and parameter configuration according to the original policy information.

Wherein, the control device #1 performs the location monitoring of the optimized UE through the access device #1, so that it can judge whether the optimization strategy #A is suitable according to the changed UE location information. If it is not applicable, the strategy execution network element restores the original UE. Policy information, the network element on the target side performs resource allocation and parameter configuration according to the original policy information.

In this embodiment of the present application, the control device #1 is used as a policy execution network element to perform location monitoring of the UE #1 through the access device #1, so as to determine whether the policy #A is suitable for the policy #A according to the location change information of the UE #1 .

The process of controlling device #1 to perform policy validity protection may be implemented through S307-S309.

After the access device #1 executes the policy #A on the UE #1 according to the indication information #2 sent by the control device #1, when the UE #1 moves, it may move out of the effective applicable area. Therefore, location monitoring of UE#1 can be performed to further determine whether UE#1 still applies to policy #A.

S307, the control device #1 sends a request message #1 to the access device #1.

The request message #1 is used to request the access device #1 to monitor the location change of the UE#1, and at the same time report the location information and UE ID of the UE#1 with the location change to the control device #1.

Wherein, the control device #1 sends a request message #1 to the access device #1 according to the applicable area or the monitoring execution instruction in the indication information #1.

The request message #1 may also include the UE ID of the UE #1 that has implemented the optimization strategy #A, so that it can be used by the access device #1 to monitor the location of the UE #1, that is, only for the implementation of the first strategy. The UE performs location monitoring.

At S308, the access device #1 performs location monitoring on the UE #1 according to the request message #1.

Specifically, the access device #1 may acquire the location information of the UE #1 based on the measurement report of the UE #1. For example, the location information of UE#1 is acquired as cell#1. The location information of UE#1 may change, for example, to cell#2. The QoE of UE#1 in cell #2 may be different from the QoE in cell #1, and the access device #2 (an example of the second access device) in cell #2 may still follow the policy #A corresponding to cell #1. The UE#1 performs resource allocation and parameter configuration, which may result in waste of resources and cannot reasonably use the resources of cell #2.

At S309, the access device #1 sends a report message #1 to the control device #1.

The report message #1 includes the location information of UE #1 and the corresponding UE ID.

When the location of UE#1 changes and needs to be handed over to access device #2, access device #1 will not directly send a handover command, but send the current location information of UE#1 to control device #1, and wait for control Further handover indication for device #1.

In a possible implementation manner, the access network device #1 may actively report the location change of the UE #1 periodically or periodically, that is, the access device #1 does not need to send the request message #1 by the control device #1, and the access device #1 takes the initiative The report message #1 is sent, so that the control device #1 can judge according to the position change. That is, S307 is an optional step.

At S310, the control device #1 determines whether the UE #1 applies the policy #A according to the report message #1.

Specifically, the location information of UE#1 is compared with the applicable area information obtained in step S304 to determine whether the location of UE#1 is included in the applicable area, and if it is within the applicable area, it is determined that the applicable policy of UE#1 is the policy #A; If it is not within the applicable area, it is judged that UE#1 is not applicable to policy #A, the applicable policy is policy #B, and policy #B needs to be restored.

At S311, the control device #1 sends indication information #3 to the access device #1.

Indication information #3 is used to indicate whether UE#1 is located in the above applicable area; or, indication information #3 is used to indicate whether UE#1 is applicable to policy #A; or, indication information #3 is used to indicate whether it is UE#1 Recovery Strategy #B.

The applicable policy sent in S202 may be represented by the above-mentioned indication information #3.

Indication information #3 may be used to instruct access device #1 to trigger a handover instruction to UE #1 and execute a corresponding policy.

Specifically, the indication of the indication information #3 to the access device #1 is divided into two cases:

The first case is that, in step S310, the control device #1 determines that the location of the UE#1 is not within the above applicable area, that is, it determines that the UE#1 is not applicable to the policy #A, that is, the control device #1 determines to restore the policy to the UE#1 #B. Indication information #3 is used to indicate that UE#1 is not located in the above applicable area; or, indication information #3 is used to indicate that UE#1 is not applicable to policy #A; or, indication information #3 is used to indicate that UE#1 is restored Strategy #B.

The second case is that, in step S310, the control device #1 determines that the location of the UE#1 is within the above applicable area, that is, it determines that the UE#1 is still applicable to the policy #A, that is, the control device #1 determines to use the policy for the UE#1 #A. Indication information #3 is used to indicate that UE#1 is located in the above applicable area; or, indication information #3 is used to indicate that UE#1 is applicable to policy #A; or, indication information #3 is used to indicate that the policy is not to be restored for UE#1 #B.

The indication information #3 may include the UE ID of the UE #1. Indication information #3 may also include policy #B. Indication information #3 may also include policy #A. The indication information #3 and the above-mentioned UE ID may be included in the same message or data structure to indicate that the indication information #3 acts on the UE #1 or corresponds to the UE #1. Indication information #3 and the above-mentioned policy #B or policy #A may be included in the same message or data structure.

The access device #1 receives the above-mentioned indication information #3, and when the indication information #3 indicates whether the UE#1 is located in the above-mentioned applicable area, the access device #1 determines that the applicable policy is policy #A or policy according to the indication information #3 #B, and instructs access device #2 to use the corresponding policy to configure parameters for UE #1; when indication #3 is used to indicate whether UE #1 is applicable to policy #A, access device #1 directly determines according to the instruction The applicable policy is policy #A or policy #B, and instructs access device #2 to use the corresponding policy to configure parameters for UE #1; when indication #3 is used to indicate whether policy #B is restored for UE #1, access Device #1 restores policy #B or uses policy #A for UE #1 according to the instruction, and further instructs the access device to switch and use the current policy for parameter configuration.

It should be noted that, in this embodiment of the present application, UE#1 is only used as an example. Among multiple UEs, if some UE#x are applicable to policy #A and some UE#y are applicable to policy #B, the The indication information #3 indicates the UE ID and policy #A of UE#x, and the UE ID and policy #B of UE#y. Two indication information can also be used to indicate separately. The embodiments of the present application are not limited.

At S312, access device #1 sends indication information #4 to access device #2.

Access device #1 executes a handover command to UE #1 to switch to access device #2.

Access device #1 sends indication information #4 to access device #2 according to indication information #3.

Indication information #4 may be used to instruct access device #2 to perform a corresponding policy on UE #1 in cell #2. That is, based on the first case in S311, the indication information #4 may include policy #B; based on the second case in S311, the indication information #4 may include policy #A.

Exemplarily, the indication information #3 includes policy #A, policy #B and the UE ID of UE #1, then modify the QOE parameter in policy #A to restore policy #B, and indication information #4 includes policy #B and The UE ID of UE#1; the indication information #3 includes policy #A and the UE ID of UE#1, then policy #A is executed, and the indication information #4 includes the UE ID of UE#1.

In S313, the access device #2 performs the mobile handover processing flow according to the indication information #4 sent by the access device #1, and performs resource allocation and parameter configuration according to the corresponding policy.

Therefore, according to the embodiment of the present application, the control device #1 determines the applicable strategy of the current mobile location of the UE based on the monitoring of the mobile location of the UE, and instructs the access device to execute the applicable strategy, which ensures that the UE can adjust the strategy in time after the UE moves. Ensure that the UE uses an appropriate policy on the target access device to avoid excessive allocation of radio resources and waste of resources due to improper policy application, thereby improving the utilization rate of radio resources. In addition, in this embodiment, the control device #1 monitors the location of the UE in real time, so as to ensure the effectiveness of the policy.

At S409, the control device #1 determines whether the UE #1 applies the policy #A based on the predicted location information.

Specifically, the predicted location information of UE#1 is compared with the applicable area information obtained in step S404 to determine whether the predicted location area of UE#1 is included in the applicable area, and if it is within the applicable area, it is determined that UE#1 is still applicable If it is not within the applicable area, it is judged that UE#1 is not applicable to policy #A, and policy #B needs to be restored.

At S410, the control device #1 sends indication information #5 to the access network device #1, where the indication information #5 is used to indicate the judgment result of the control device #1.

Specifically, the indication information #5 indicates to the access device #1 is divided into two cases:

The first case is that, in step S409, control device #1 determines that UE#1 is not within the above applicable area according to the predicted location information, that is, UE#1 that determines the predicted location is not suitable for strategy #A, that is, the prediction of control device #1 The location is outside the applicable area, policy #B applies. Indication information #5 is used to indicate that UE#1 of the predicted position is not located in the above applicable area; or, the indication information #5 is used to indicate that the UE#1 of the predicted position is not applicable to strategy #A; or, the indication information #5 is used to The UE#1 recovery strategy #B is indicated as the predicted location. The indication information #5 specifically includes the predicted location information of UE#1, policy #A, policy #B, and the UE ID of UE#1.

The second case is that, in step S409, control device #1 determines that the predicted location of UE #1 is within the above applicable area according to the predicted location information, that is, it is still applicable to strategy #A, that is, control device #1 determines that the predicted location of UE #1 is within the above-mentioned applicable area. #1 Use strategy #A. Indication information #5 is used to indicate that UE#1 is located in the above applicable area; or, indication information #5 is used to indicate that UE#1 is suitable for policy #A; or, indication information #5 is used to indicate that the policy is not to be restored for UE#1 #B. The indication information #5 specifically includes the predicted location information of the UE#1, the policy #A and the UE ID of the UE#1.

Indication information #5 may include UE ID and predicted location information of UE #1. Indication information #5 may also include policy #B. Indication information #5 may also include policy #A. The indication information #5 and the above-mentioned UE ID and predicted location information may be included in the same message or data structure to indicate that the indication information #5 acts on UE#1 or corresponds to UE#1. The indication information #5 and the above-mentioned policy #B or policy #A may be included in the same message or data structure.

At S411, the access device #1 executes the policy according to the indication information #5 based on the actual location information of the UE #1.

That is to say, the access device #1 monitors the actual location change of UE#1, and when the actual location change is the same as the predicted location information in the indication information #5, it executes according to the policy indicated in the indication information #5.

The access device #1 receives the above-mentioned indication information #5, when the indication information #5 indicates whether the UE#1 with the predicted location is located in the above applicable area, the access device #1 according to the indication information #3 and the actual situation of the UE#1 The location information determines that the applicable policy is policy #A or policy #B, and instructs access device #2 to use the corresponding policy to configure parameters for UE #1. For example, if the indication information #5 includes that the predicted location of UE#1 is outside the applicable area, the access device #1 first determines whether the predicted location and the actual location are the same, and if they are the same, it is determined that the actual location is also outside the applicable area, so it can be Be sure to use strategy #B. When the indication information #3 is used to indicate whether the UE#1 of the predicted location is applicable to the strategy #A, the access device #1 directly determines the applicable strategy as the strategy #A or the strategy #B according to the indication and the actual location information of the UE #1 , and instructs the access device #2 to use the corresponding strategy to configure the parameters for UE #1; when the indication information #3 is used to indicate whether it is the UE#1 of the predicted location to restore the strategy #B, the access device #1 according to the instruction and the UE#1 The actual location information of #1 is UE#1 recovering policy #B or using policy #A, which further instructs the access device to switch and use the current policy for parameter configuration.

In a possible implementation manner, if the actual position information is different from the predicted position information, the execution starts from step S309 according to the first case.

Subsequent steps are the same as S312-S313 in the first method, and are not described repeatedly to avoid redundant description.

Therefore, according to the embodiment of the present application, the control device #1 performs mobile location prediction for the UE based on the UE information, and sends the predicted location information or the policy decision result based on the predicted location information to the access device #1 in advance, and the access device #1 according to The monitored actual location information is compared with the predicted location information to determine the final strategy, which ensures that the UE can adjust the strategy in time after the UE moves, and ensures that the UE uses the appropriate strategy in the access device #2 to avoid excessive wireless resources caused by improper application of the strategy. The problem of allocation, waste of resources, thereby improving the utilization rate of wireless resources. In addition, in this embodiment, the access device makes policy decisions according to the monitored actual location information and predicted location information, which avoids signaling overhead caused by sending a report message to control device #1.

In the embodiment of the present application, the access network device #1, as an executing network element, directly monitors the location of UE#1, so as to determine whether UE#1 is suitable for policy #A when the location of UE#1 changes.

The process of controlling device #1 to perform policy validity protection may be implemented through S507-S508.

In this way, different from step S305, the indication information #1 forwarded by the control device #1 to the access device #1 includes, in addition to the ID of the policy #A and UE#1, the applicable area information for Instruct access device #1 to execute policy #A on UE #1, and then monitor the location of UE #1 and determine whether policy #A is applicable according to the monitoring result.

At S507, the access device #1 performs location monitoring on the UE#1.

In S508, the access device #1 determines whether the UE #1 applies the policy #A according to the monitored actual location information (an example of the first location) and executes the corresponding policy.

Specifically, the actual location information of UE#1 is compared with the applicable area information obtained in step S304 to determine whether the location area of UE#1 is included in the applicable area, and if it is within the applicable area, it is determined that UE#1 is still applicable to Policy #A; if it is not within the applicable area, it is determined that UE#1 is not applicable to policy #A, policy #B needs to be restored, and the corresponding policy is executed for UE#1 as a result of the determination.

Subsequent steps are the same as steps S312-S313 of the method 300, and will not be described repeatedly to avoid redundant description.

Therefore, through the embodiment of the present application, the access device performs UE location monitoring and policy decision, which ensures that the UE can adjust the policy in time after the UE moves, and ensures that the UE uses an appropriate policy in the access device #2, so as to avoid improper application of policies that may lead to The problem of excessive allocation of wireless resources and waste of resources, thereby improving the utilization rate of wireless resources. In addition, in this embodiment, the access device is completely responsible for UE location monitoring and policy decision, avoiding signaling overhead caused by a large number of signaling interactions with control device #1.
