In order to facilitate a better understanding of the embodiments of the present invention, the following technical points are first described.

The following requirements exist for guaranteeing the round trip delay in media services such as Extended Reality (XR):

whether and how uplink-downlink transmission coordination is supported to meet Round Trip delay (RTT) requirements between the terminal and the N6 endpoint at the user plane function (User plane Function, UPF).

Naturally, the imbalance of the uplink and downlink delays of the service is caused. Taking a game service as an example, an uplink data packet (such as an action packet of a user) is smaller, and the uplink data packet needs to be sent to a server more quickly to avoid picture jitter, so that the delay budget is relatively smaller; the downlink data packets (such as background frames and status packets of the game) are relatively large, and the delay budget requirement is relatively large.

Currently, a QoS flow has only one delay budget, and the uplink delay budget is the same as the downlink delay budget. Thus, to optimize the user experience, the following problems are also solved:

how to satisfy the round trip delay overhead, for example, the round trip delay overhead is guaranteed by the difference between uplink and downlink, and the uplink and downlink delay overhead does not exceed the round trip delay overall.

Executing at least one of the following according to the round trip delay requirement of the service: splitting the round trip delay requirement of the service into an uplink delay requirement and a downlink delay requirement of the service, mapping the delay budget in the second QoS requirement according to the split uplink delay requirement, and mapping the QoS identifier in the second QoS requirement according to the split uplink delay requirement;

executing at least one of the following according to the uplink time delay requirement of the service: mapping delay budget in the second QoS requirement according to the uplink delay requirement of the service, and mapping QoS identifier in the second QoS requirement according to the uplink delay requirement of the service;

In one embodiment, the sum of the upstream and downstream delay budgets of the first lane does not exceed the round trip delay budget of the first lane.

In one embodiment, the first information includes an uplink delay requirement of the service and a downlink delay requirement of the service, and the specific implementation of the first QoS requirement determined by the first communication device is as follows: the uplink delay requirement (which may be referred to as a first uplink delay requirement) of the service is mapped to the uplink QoS requirement in the first QoS requirement, and the downlink delay requirement (which may be referred to as a first downlink delay requirement) of the service is mapped to the downlink QoS requirement in the first QoS requirement.

In one embodiment, the first information includes round trip delay requirements of a service, and the specific implementation of the first QoS requirement determined by the first communication device is as follows: splitting based on the round trip delay requirement of the service to obtain an uplink delay requirement (which can be called a second uplink delay requirement) of the service and a downlink delay requirement (which can be called a second downlink delay requirement) of the service, mapping the two uplink delay requirements to the uplink QoS requirement in the first QoS requirement, and mapping the second downlink delay requirement to the downlink QoS requirement in the first QoS requirement. The division of the round trip delay requirement of the service can be performed according to a preconfigured round trip delay division experience value or a QoS monitoring result. The round trip delay separation experience value may be 1/2.

In one embodiment, the first communication device may use 1/2 of the round trip delay requirement of the service as the uplink delay requirement of the service, so as to map the uplink delay requirement of the service to the uplink delay budget of the first QoS requirement; for example, in the absence of a first QoS identifier mapping having a delay budget equal to 1/2 round trip delay requirement, the first QoS requirement includes an uplink delay budget equal to 1/2 round trip delay requirement and a first QoS identifier having a value different from 1/2 round trip delay requirement. Since the upstream delay budget has a higher priority than the first QoS id Fu Gao, the upstream delay budget at the first QoS requirement is a 1/2 round trip delay requirement.

In one embodiment, 1/2 of the round trip delay requirement of the service is taken as the downlink delay requirement of the service, so that the downlink delay requirement of the service is mapped to the first QoS identifier of the first QoS requirement. For example, in the absence of a delay budget for the first QoS identifier mapping equal to 1/2 round-trip delay requirement, the first QoS requirement includes the first QoS identifier, so the value of the round-trip delay requirement is 1/2 at the upstream delay budget of the first QoS requirement.

So, for example, where the first QoS requirement includes the first upstream delay budget and the first QoS identifier, the value of the first upstream delay budget is equal to the 1/2 round trip delay requirement, and the value of the corresponding downstream delay budget (which may be referred to as the second upstream delay budget) of the first QoS identifier is also equal to the 1/2 round trip delay requirement.

In an alternative embodiment of the present invention, before the first communication device obtains the third information, the method further includes:

the first communication device performs at least one of the following according to the first information:

wherein the delay monitoring requirement comprises at least one of: the delay monitoring requirement of the first channel, the delay monitoring requirement of the second channel, the delay monitoring requirement of the third channel and the delay monitoring requirement of the data flow of the service; and/or, the delay monitoring requirement comprises at least one of:

Alternatively, delay monitoring requirements may be used to monitor delay overhead in the channel. The uplink delay monitoring is required to monitor the uplink delay overhead. The downstream delay monitoring is required to monitor downstream delay overhead.

Optionally, the first communication device sends the delay monitoring requirement of the channel to the target device B (e.g., the third communication device). The delay monitoring requirements may enable the target device B to determine a delay monitoring configuration and/or transmit the delay monitoring configuration according to the delay monitoring requirements of the channel. For example, in the case where the first communication device is a PCF, the target device B may be an SMF. For example, in the case where the first communication device is an SMF, the target device B may be at least one of: gateway (e.g., UPF), RAN, terminal.

The channel may include: a first channel, a second channel and a third channel.

The QoS control method according to the embodiment of the present invention is described below with reference to a specific application scenario.

The application scenario 1 of the embodiment of the present invention mainly describes that the first communication device is PCF, the second communication device is AF, the third communication device is SMF, the fourth communication device is RAN and UPF, and the PCF determines the first QoS requirement directly based on the delay requirement of the service, so as to complete the QoS configuration process. Referring to fig. 7, the method comprises the following steps:

step 1: the AF sends first information (e.g., round trip delay requirements) to the NEF. The first information is carried by an AF session creation request.

The first information is as described in the embodiment of fig. 2, and is not described herein.

Step 2: the NEF sends first information (e.g., round trip delay requirements) to the PCF. The first information is carried by a policy authorization creation request.

Step 3: the PCF returns a policy authorization creation response to the NEF.

Step 4: the NEF returns an AF session creation response to the AF.

Step 5: the PCF determines to perform a first operation (e.g., determine a first QoS requirement) based on the first information (e.g., round trip delay requirement). Here, the first QoS requirement may be a QoS requirement for a first lane (first QoS flow).

The first QOS requirements include an upstream QOS requirement and a downstream QOS requirement. The upstream QoS requirements include at least one of: uplink 5QI (first uplink 5 QI), and uplink delay budget (first uplink delay budget). The downstream QoS requirements include at least one of: downlink 5QI (first downlink 5 QI), and downlink delay budget (first downlink delay budget).

The first QOS requirements may also include round trip QOS requirements. The round trip QoS requirements include a round trip delay budget. The sum of the uplink delay budget (the uplink delay budget of the first uplink 5QI map or the first uplink delay budget) corresponding to the uplink QoS requirement and the downlink delay budget (the downlink delay budget of the first downlink 5QI map or the first downlink delay budget) corresponding to the downlink QoS requirement cannot exceed the round trip delay budget.

When the round trip delay requirements include: in the case of an uplink delay requirement and a downlink delay requirement, the PCF may determine the first QoS requirement directly from the PCF according to the round trip delay requirement. For example, determining an uplink QoS requirement according to the uplink delay requirement; and determining the downlink QoS requirement according to the downlink delay requirement.

In the case where the round-trip delay requirement includes a round-trip delay requirement, the PCF may segment the round-trip delay requirement according to a preconfigured loop delay segmentation experience value or a QoS monitoring result, and then determine the uplink QoS requirement and the downlink QoS requirement. For example, in a game service, the uplink data packet is smaller, often the action packet of the user, and the action packet is sent to the server as soon as possible to avoid the jitter of the picture, so that the delay budget is smaller. The downlink data packet is larger, often the background picture and status packet of the game, and the delay budget requirement can be larger.

In one embodiment, the first QoS requirement includes an uplink 5QI and a downlink 5QI. The uplink 5QI is a standard 5QI when the uplink latency requirement can map the standard 5QI. The same applies to the downlink.

In another embodiment, the first QoS requirement has no uplink 5QI and no downlink 5QI. There is a 5QI in the first QoS requirement, and an upstream delay budget and/or a downstream delay budget. And the uplink delay budget and/or the downlink delay budget are/is valued according to the standard delay budget corresponding to the direction override 5QI.

In one embodiment, the first QoS requirement has a delay budget of 5QI and an uplink delay budget, and the uplink delay budget value used based on the first QoS requirement is the uplink delay budget, and the downlink delay budget value is the delay budget value corresponding to the 5QI.

In another embodiment, the first QoS requirement has a delay budget of 5QI and a delay budget of 5QI, and the delay budget corresponding to the delay budget of 5QI is set as the delay budget of the first QoS requirement.

Step 6: the PCF sends the second information (e.g., the first QoS requirement) to the SMF (e.g., contained in the PCC rule). The first QoS requirement is carried in a session management policy control update notification request. Of course, the PCF may also send the ring first information directly to the SMF.

The second information is as described in the embodiment of fig. 2, and is not described herein.

Step 7: the SMF performs a second operation (e.g., determines a first QoS configuration) based on the second information (e.g., the first QoS requirement). The first QoS configuration is a QoS requirement for configuring a first QoS flow.

The first QOS configuration includes an upstream QOS configuration and a downstream QOS configuration. The upstream QoS configuration includes at least one of: uplink 5QI (second uplink 5 QI), and uplink delay budget (third uplink delay budget). The downstream QoS configuration includes at least one of: downlink 5QI (second downlink 5 QI), and downlink delay budget (third downlink delay budget).

The first QOS configuration may also include a round trip QOS configuration. The round trip QoS configuration includes a round trip delay budget. The sum of the uplink delay budget (the uplink delay budget of the second uplink 5QI mapping or the third uplink delay budget) and the downlink delay budget (the downlink delay budget of the second downlink 5QI mapping or the third downlink delay budget) corresponding to the uplink QoS configuration cannot exceed the round trip delay budget.

In one embodiment, the first QoS configuration has an uplink 5QI and a downlink 5QI. The uplink 5QI is a standard 5QI when the uplink latency requirement can map the standard 5QI. The same applies to the downlink.

In another embodiment, the first QoS configuration has no uplink 5QI and no downlink 5QI. The first QoS configuration has a 5QI and an upstream delay budget and/or a downstream delay budget. And the uplink delay budget and/or the downlink delay budget are/is valued according to the standard delay budget corresponding to the direction override 5QI.

In one embodiment, the first QoS configuration has a delay budget of 5QI and an uplink delay budget, and the uplink delay budget value used based on the first QoS configuration is the uplink delay budget, and the downlink delay budget is the delay budget value corresponding to 5QI.

In another embodiment, the first QoS configuration has a delay budget of 5QI and a delay budget of downlink, and the delay budget of uplink is a delay budget corresponding to 5QI based on the delay budget of downlink used in the first QoS configuration.

Of course, if the PCF sends the round trip delay requirement to the SMF, the SMF may also determine the first QoS configuration according to the round trip delay requirement, and the process of determining the first QoS configuration according to the first QoS requirement is specifically implemented, which is not described herein.

Step 8:

the SMF sends fourth information (e.g., the first QoS configuration) to the RAN via the AMF. The first QoS configuration is carried in an N1 or N2 message.

The SMF sends fourth information (e.g., the first QoS configuration) to the UPF. The first QoS configuration is carried in an N4 session modification request, which is sent after the channel is established.

The SMF sends the first QoS context to the UE. The UE maps the data flow of the service to the first QoS flow according to the first QoS context.

The fourth information is as described in the embodiment of fig. 4, and is not described here again

Step 9: the RAN performs a fourth operation (e.g., qoS securing the data packets in the first QoS flow) according to the fourth information (e.g., the first QoS configuration) to satisfy the requirements of the first QoS configuration.

Step 10: the UPF performs a fourth operation (e.g., qoS securing for the data packets in the first QoS flow) according to fourth information (e.g., the first QoS configuration) to satisfy the requirements of the first QoS configuration.

Application scenario 2 of the embodiment of the invention:

the application scenario 2 of the embodiment of the present invention mainly describes a process in which the first communication device is PCF, the second communication device is AF, the third communication device is SMF, the fourth communication device is RAN and UPF, and the PCF adjusts the first QoS requirement based on the result of the delay monitoring and the delay requirement. Referring to fig. 8, the method comprises the following steps:

Step 1-4 is the same as step 1-4 of application scenario 1, and will not be described here again.

Step 5: the PCF performs a first operation (e.g., determines a delay monitor requirement) based on the first information (e.g., the round trip delay requirement). The delay monitoring is required to monitor delay overhead in the first QoS flow.

The delay monitoring requirements include an uplink delay monitoring requirement and a downlink delay monitoring requirement. The uplink delay monitoring is required to monitor the uplink delay overhead. The downstream delay monitoring is required to monitor downstream delay overhead.

The delay monitoring requirements may also include round trip delay requirements.

Reporting events can be monitored in the monitoring process, and the sum of the uplink delay overhead and the downlink delay overhead exceeds the round trip delay requirement.

Step 6: the PCF sends a second message (e.g., delay monitoring requirements) to the SMF (e.g., contained in the PCC rule). The second information is carried in a session management policy control update notification request.

Step 7: the SMF performs a second operation (e.g., determining a latency monitoring configuration) based on second information (e.g., latency monitoring requirements). The delay monitor configuration is a QoS requirement for configuring the first QoS flow.

Step 8:

the SMF sends fourth information (e.g., delay monitoring configuration) to the RAN via the AMF. The fourth information is carried in an N1 or N2 message.

The SMF sends fourth information (e.g., delay monitor configuration) to the UPF. The fourth information is carried in an N4 session modification request, which is sent after the channel is established.

The fourth information is as described in the embodiment of fig. 4, and is not described here again.

Step 9: the RAN performs a fourth operation (e.g., delay monitoring on the packets in the first QoS flow) according to fourth information (e.g., delay monitoring configuration), specifically as defined by 501QoS monitoring (monitoring).

Step 10: the UPF performs a fourth operation (e.g., delay monitoring on the packets in the first QoS flow) according to fourth information (e.g., delay monitoring configuration), specifically as defined by 501QoS monitoring.

Step 11: the PCF subscribes to the UPF for the time delay detection result.

In one embodiment, the PCF sends subscription requirements to the UPF, which may include: the first monitoring reports the incident, the information of UE, the information of QoS flow, the description information of service flow, the uplink delay cost and the downlink delay cost.

Step 12: the PCF obtains the fifth information, and performs a fifth operation (e.g., making a measurement decision, combining the result of the delay monitoring and the delay requirement to adjust the first QoS requirement) according to the fifth information.

The fifth information is as described in the embodiment of fig. 6, and is not described herein.

Application scenario 3 of the embodiment of the invention: similar to application scenario 1 shown in fig. 7, however, in step 1 the first information does not comprise the round trip delay requirement of the traffic.

In step 5, the PCF takes the half value of the round trip delay requirement as the round trip delay requirement of the service.

Application scenario 4 of the embodiment of the invention:

similar to the application scenario 1 of fig. 7, the steps 1 to 4 are not repeated.

In step 5, the PCF determines to perform the first operation according to the first information (such as round trip delay requirement), specifically including mapping, for the service, a channel (second channel, such as a second QoS flow) for transmitting uplink data of the service and a channel (third channel, such as a third QoS flow) for transmitting downlink data of the service, respectively. Thus, the related processing of the first QoS flow in the subsequent steps of the application scenario 1 is modified to be related processing corresponding to the second QoS flow and the third QoS flow, which is not described herein.
