Of course, the described embodiments are only a part of the embodiments of the present application, and are not all of the embodiments.

Also, "and / or" as used in the specification and claims indicates at least one of the connected objects, e.g., A and / or B indicates three cases: only A is present, only B is present, and both A and B are present.

[0027] In the embodiments of the present application, the use of terms such as "exemplary" or "for example" is intended to indicate an example, illustration, or explanation. Any embodiment or design described in the embodiments of the present application as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs.

[0028] The techniques described in this specification are not limited to 5th-generation (5G) systems and future evolved communication systems, as well as Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but may also be used in various wireless communication systems and other systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), etc.

[0029] The terms "system" and "network" are often used interchangeably. A CDMA system can implement radio technologies such as CDMA2000, Universal Terrestrial Radio Access (UTRA), etc. UTRA includes Wideband Code Division Multiple Access (WCDMA) and other CDMA variations.

An OFDMA system can implement radio technologies such as Ultra Mobile Broadband (UMB), Evolution-UTRA (E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, etc. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS).

CDMA2000 and UMB are described in documents from an organization called "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein may be used in the systems and radio technologies mentioned above, as well as other systems and radio technologies.

[0030] In order to facilitate a better understanding of the embodiments of the present application, the following technical points will be first introduced.

[0031] In media services such as Extended Reality (XR), it is becoming necessary to guarantee round trip delay. That is, whether and how to support uplink-downlink transmission coordination in order to meet the round trip time (RTT) requirements between the terminal and the N6 endpoint in the User Plane Function (UPF).

[0032] Of course, the main reason is the imbalance of uplink and downlink delays of services. Take game services as an example, the uplink data packets (e.g., user action packets) are relatively small and need to be sent to the server faster to avoid screen blur, resulting in a relatively small delay budget. However, the downlink data packets (e.g., game background and state packets) are relatively large, resulting in a relatively large delay budget requirement.

[0033] Currently, one QoS flow has only one delay budget, and the uplink delay budget and the downlink delay budget are the same. Therefore, in order to optimize the user experience, the following problems need to be solved: How to meet the round trip delay overhead, for example, to guarantee differential uplink and downlink delays, and ensure that the uplink and downlink delay overheads do not exceed the total round trip delay.

[0144] In an alternative embodiment of the present application, the sum of the uplink delay requirement and the downlink delay requirement of the service does not exceed at least one of the following: a round trip delay requirement of the service, and twice the first delay requirement of the service.

[0145] In one embodiment, the sum of the uplink delay budget and the downlink delay budget of the first channel does not exceed the round trip delay budget of the first channel.

[0146] In one embodiment, the first information includes an uplink delay requirement of a service and a downlink delay requirement of a service, and the first communication device determines the first QoS requirement as follows: map an uplink QoS requirement in the first QoS request to an uplink delay requirement of the service (which may be referred to as a first uplink delay requirement), and map a downlink QoS requirement in the first QoS request to a downlink delay requirement of the service (which may be referred to as a first downlink delay requirement).

[0147] In one embodiment, the first information includes a round trip delay requirement of a service, and the first communication device determines the first QoS requirement as follows: That is, an uplink delay requirement of the service (which may be referred to as a second uplink delay requirement) and a downlink delay requirement of the service (which may be referred to as a second downlink delay requirement) are obtained by dividing based on the round trip delay requirement of the service, the uplink QoS requirement in the first QoS request is mapped to the second uplink delay request, and the downlink QoS requirement in the first QoS request is mapped to the second downlink delay request. Here, the division of the round trip delay requirement of the service may be performed according to a pre-configured empirical round trip delay division value or a result of QoS monitoring. The empirical round trip delay division value may be 1 / 2.

[0148] In an embodiment, the first communication device can map the uplink delay budget of the first QoS request to the uplink delay requirement of the service, taking 1 / 2 of the round trip delay requirement of the service as the uplink delay requirement of the service, for example, when there is no delay budget to be mapped by the first QoS identifier that is equal to 1 / 2 round trip delay requirement, the first QoS request includes an uplink delay budget and a first QoS identifier, the value of the uplink delay budget is equal to 1 / 2 round trip delay requirement, and the downlink delay budget to be mapped by the first QoS identifier is not equal to 1 / 2 round trip delay requirement, the first communication device takes 1 / 2 round trip delay requirement as the value of the uplink delay budget of the first QoS request, because the priority of the uplink delay budget is higher than the first QoS identifier.

[0149] In one embodiment, the first QoS identifier of the first QoS request is mapped to the downlink delay requirement of the service, with 1 / 2 of the round trip delay requirement of the service being the downlink delay requirement of the service. For example, when there is no delay budget to map the first QoS identifier that is equal to 1 / 2 the round trip delay requirement, the first QoS request includes the first QoS identifier, so that 1 / 2 the round trip delay requirement is taken as the value of the uplink delay budget of the first QoS request.

[0150] Thus, for example, when a first QoS request includes the first uplink delay budget and the first QoS identifier, the value of the first uplink delay budget is equal to 1 / 2 the round trip delay request, and the value of the downlink delay budget (which may be referred to as the second uplink delay budget) corresponding to the first QoS identifier is also equal to 1 / 2 the round trip delay request.

[0209] Optionally, the fifth information is transmitted from a source device E (eg, a third communication device), the source device E including at least one of an SMF and a PCF.

[0210] According to an embodiment of the present application, after the fifth communication device obtains the fifth information, it performs a fifth operation according to the fifth information to achieve the purpose of round trip delay compensation.

[0211] Next, a QoS control method according to an embodiment of the present invention will be described in conjunction with a specific use case. (Use case 1 of the embodiment of the present application)

[0212] Use case 1 of the embodiment of the present application mainly describes a procedure in which, when the first communication device is a PCF, the second communication device is an AF, the third communication device is an SMF, and the fourth communication device is a RAN and a UPF, the PCF determines the first QoS requirement directly based on the delay requirement of the service to complete the QoS configuration. As shown in Figure 7, the use case 1 includes the following steps 1 to 10:

[0213] Step 1: The AF sends first information (e.g., a round trip delay request) to the NEF, which is carried in a create AF session request.

[0214] The first information is the same as that described in the embodiment of FIG. 2, and a detailed description thereof will be omitted here.

[0215] Step 2: The NEF sends first information (eg, a round trip delay request) to the PCF, which is carried in a policy authorization creation request.

[0216] Step 3: The PCF returns a policy authorization create response to the NEF.

[0217] Step 4: The NEF returns an AF session creation response to the AF.

[0218] Step 5: The PCF determines to perform a first operation (e.g., determine a first QoS requirement) according to the first information (e.g., round trip delay requirement), where the first QoS requirement may be a QoS requirement for a first channel (a first QoS flow).

[0219] The first QOS request includes an uplink QoS request and a downlink QoS request. The uplink QoS request includes at least one of an uplink 5QI (first uplink 5QI) and an uplink delay budget (first uplink delay budget). The downlink QoS request includes at least one of a downlink 5QI (first downlink 5QI) and a downlink delay budget (first downlink delay budget).

[0220] The first QoS requirement may further include a round-trip QoS requirement. The round-trip QoS requirement includes a round-trip delay budget. A sum of an uplink delay budget (uplink delay budget mapped to the first uplink 5QI or first uplink delay budget) corresponding to the uplink QoS requirement and a downlink delay budget (downlink delay budget mapped to the first downlink 5QI or first downlink delay budget) corresponding to the downlink QoS requirement cannot exceed the round-trip delay budget.

[0221] When the round trip delay requirement includes an uplink delay requirement and a downlink delay requirement, the PCF can directly determine the first QoS requirement according to the round trip delay requirement, for example, determine the uplink QoS requirement according to the uplink delay requirement, and determine the downlink QoS requirement according to the downlink delay requirement.

[0222] When the round trip delay requirement includes one round trip delay requirement, the PCF can divide the round trip delay requirement according to the pre-configured loop delay division experience value or the result of QoS monitoring to determine the uplink QoS requirement and the downlink QoS requirement. For example, in a game service, the uplink data packets are relatively small and are generally user action packets, and need to be sent to the server as quickly as possible to avoid screen blur, so the delay budget is relatively small. The downlink data packets are relatively large and are generally game background screens or state packets, so the delay budget requirement can be large.

[0223] 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 delay requirement can be mapped to a standard 5QI. The downlink is similar.

[0224] In another embodiment, the first QoS requirement does not have an uplink 5QI and a downlink 5QI. The first QoS requirement has one 5QI and an uplink delay budget and / or a downlink delay budget. The uplink delay budget and / or the downlink delay budget are valued according to the standard delay budget corresponding to the direction override 5QI.

[0225] In one embodiment, the first QoS requirement has one 5QI and uplink delay budget, so the value of the uplink delay budget used according to the first QoS requirement is the uplink delay budget, and the value of the delay budget corresponding to the 5QI is the value of the downlink delay budget.

[0226] In another embodiment, the first QoS requirement has a 5QI and a downlink delay budget, so the value of the downlink delay budget used based on the first QoS requirement is the downlink delay budget, and the value of the delay budget corresponding to the 5QI is the value of the uplink delay budget.

[0227] Step 6: The PCF sends the second information (e.g., the first QoS request) to the SMF (e.g., included in the PCC rule). The first QoS request is carried in a session management policy control update notification request. Of course, the PCF may send the first information directly to the SMF.

[0228] The second information is the same as that described in the embodiment of FIG. 2, and a detailed description thereof will be omitted here.

[0229] Step 7: The SMF performs a second operation (eg, determines a first QoS configuration) according to the second information (eg, the first QoS requirement), where the first QoS configuration is used to configure the QoS requirement of the first QoS flow.

[0230] The first QOS configuration includes an uplink QoS configuration and a downlink QoS configuration. The uplink QoS configuration includes at least one of an uplink 5QI (a second uplink 5QI) and an uplink delay budget (a third uplink delay budget). The downlink QoS configuration includes at least one of a downlink 5QI (a second downlink 5QI) and a downlink delay budget (a third downlink delay budget).

[0231] The first QoS configuration may further include a round-trip QoS configuration. The round-trip QoS configuration includes a round-trip delay budget. A sum of an uplink delay budget (uplink delay budget mapped by the second uplink 5QI or a third uplink delay budget) and a downlink delay budget (downlink delay budget mapped by the second downlink 5QI or a third downlink delay budget) corresponding to the uplink QoS configuration cannot exceed the round-trip delay budget.

[0232] 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 delay requirement can be mapped to the standard 5QI. The downlink is similar.

[0233] In another embodiment, the first QoS configuration has no uplink 5QI and no downlink 5QI. The first QoS configuration has one 5QI and an uplink delay budget and / or a downlink delay budget. The uplink delay budget and / or the downlink delay budget are valued according to the standard delay budget corresponding to the direction override 5QI.

[0234] In one embodiment, the first QoS configuration has one 5QI and uplink delay budget, so the value of the uplink delay budget used according to the first QoS configuration is the uplink delay budget, and the value of the delay budget corresponding to the 5QI is the downlink delay budget.

[0235] In another embodiment, the first QoS configuration has one 5QI and a downlink delay budget, so that the value of the downlink delay budget used according to the first QoS configuration is the downlink delay budget, and the value of the delay budget corresponding to the 5QI is the uplink delay budget.

[0236] Of course, when the PCF sends a round trip delay request to the SMF, the SMF can also determine the first QoS configuration according to the round trip delay request. The specific implementation is the same as the procedure of determining the first QoS configuration according to the first QoS request, and detailed description is omitted here.

[0237] Step 8: The SMF sends the fourth information (eg, a first QoS configuration) to the RAN via the AMF, where the first QoS configuration is carried in an N1 or N2 message. The SMF sends the fourth information (eg, the first QoS configuration) to the UPF, which is carried in an N4 session modify request, and the N4 session modify request is sent after the channel is established. The SMF sends the first QoS context to the UE, and the UE maps the first QoS flow to a data flow of the service according to the first QoS context.

[0238] The fourth information is the same as that described in the embodiment of FIG. 4, and a detailed description thereof will be omitted here.

[0239] Step 9: The RAN performs a fourth operation (eg, a QoS guarantee for the data packets in the first QoS flow) according to the fourth information (eg, the first QoS configuration) to satisfy the requirement of the first QoS configuration.

[0240] Step 10: The UPF performs a fourth operation (eg, a QoS guarantee for the data packets in the first QoS flow) according to the fourth information (eg, the first QoS configuration) to satisfy the requirement of the first QoS configuration. (Use case 2 of the embodiment of the present application)

[0241] Use case 2 of the embodiment of the present application mainly describes a procedure in which the PCF adjusts the first QoS requirement based on the result of delay monitoring and the delay requirement when the first communication device is a PCF, the second communication device is an AF, the third communication device is an SMF, and the fourth communication device is a RAN and a UPF. As shown in Figure 8, the use case 2 includes the following steps 1 to 12.

[0242] Steps 1-4 are the same as steps 1-4 in Use Case 1, and detailed explanations are omitted here.

[0243] Step 5: The PCF performs a first operation (eg, determines a delay monitoring request) according to the first information (eg, a round trip delay request), which is used to monitor the delay overhead in the first QoS flow.

[0244] The first information is the same as that described in the embodiment of FIG. 2, and a detailed description thereof will be omitted here.

[0245] The delay monitor request includes an uplink delay monitor request and a downlink delay monitor request. The uplink delay monitor request is used to monitor the uplink delay overhead. The downlink delay monitor request is used to monitor the downlink delay overhead.

[0246] The delay monitor request may further include a round trip delay request.

[0247] During monitoring, it may be possible to monitor for an annunciation event, the sum of the uplink delay overhead and the downlink delay overhead exceeding the round trip delay requirement.

[0248] Step 6: The PCF sends the second information (e.g., a delay monitoring request) to the SMF (e.g., included in a PCC rule). The second information is carried in a session management policy control update notification request.

[0249] The second information is the same as that described in the embodiment of FIG. 2, and a detailed description thereof will be omitted here.

[0250] Step 7: The SMF performs a second operation (eg, determines a delay monitoring configuration) according to the second information (eg, the delay monitoring request), where the delay monitoring configuration is used to configure the QoS requirement of the first QoS flow.

[0251] Step 8: The SMF transmits the fourth information (e.g., delay monitoring configuration) to the RAN via the AMF. This fourth information is carried in an N1 or N2 message. The SMF sends the fourth information (eg, delay monitoring configuration) to the UPF, which is carried in an N4 session modification request, and the N4 session modification request is sent after the channel is established.

[0252] The fourth information is the same as that described in the embodiment of FIG. 4, and a detailed description thereof will be omitted here.

[0253] Step 9: The RAN performs a fourth operation (eg, delay monitoring for data packets in the first QoS flow) according to the fourth information (eg, delay monitoring configuration), specifically as defined in 501 for QoS monitoring.

[0254] Step 10: The UPF performs a fourth operation (eg, delay monitoring for data packets in the first QoS flow) according to the fourth information (eg, delay monitoring configuration), specifically as defined in QoS monitoring 501.

[0255] Step 11: The PCF subscribes to the delay detection result from the UPF.

[0256] In one embodiment, the PCF sends a subscription request to the UPF, where the subscription request may include a first monitored notification event, UE information, QoS flow information, service flow description information, uplink delay overhead, and downlink delay overhead.

[0257] Step 12: The PCF obtains the fifth information and performs a fifth operation according to the fifth information (eg, measurement decision, adjusting the first QoS requirement based on the result of the delay monitoring and the delay requirement).

[0258] The fifth information is the same as that shown in the embodiment of FIG. 6, and a detailed description thereof will be omitted here. (Use case 3 of the embodiment of the present application)

[0259] Use case 3 in the present embodiment is similar to use case 1 shown in FIG. 7, except that in step 1, the first information does not include the round trip delay requirement of the service.

[0260] In step 5, the PCF takes half this round trip delay requirement as the round trip delay requirement of the service. (Use case 4 of the embodiment of the present application)

[0261] Since it is similar to use case 1 in FIG. 7, steps 1 to 4 will not be described in detail.

[0262] In step 5, the PCF determines to perform a first operation according to the first information (e.g., round trip delay request), specifically including mapping a channel (a second channel, e.g., a second QoS flow) for carrying uplink data of the service and a channel (a third channel, e.g., a third QoS flow) for carrying downlink data of the service to the service, respectively. In this way, the related processing for the first QoS flow performed in the subsequent steps in use case 1 is changed to the related processing corresponding to the second QoS flow and the third QoS flow, and the detailed description is omitted here.

[0320] In one embodiment, the first information includes an uplink delay requirement of a service and a downlink delay requirement of a service, and the first communication device determines the first QoS requirement as follows: map an uplink QoS requirement in the first QoS request to an uplink delay requirement of the service (which may be referred to as a first uplink delay requirement), and map a downlink QoS requirement in the first QoS request to a downlink delay requirement of the service (which may be referred to as a first downlink delay requirement).

[0321] In one embodiment, the first information includes a round trip delay requirement of a service, and the first communication device determines the first QoS requirement as follows: That is, an uplink delay requirement of the service (which may be referred to as a second uplink delay requirement) and a downlink delay requirement of the service (which may be referred to as a second downlink delay requirement) are obtained by dividing based on the round trip delay requirement of the service, the uplink QoS requirement in the first QoS request is mapped to the second uplink delay request, and the downlink QoS requirement in the first QoS request is mapped to the second downlink delay request. Here, the division of the round trip delay requirement of the service may be performed according to a pre-configured empirical round trip delay division value or a result of QoS monitoring.

[0322] In an embodiment, the first communication device can map the uplink delay budget of the first QoS request to the uplink delay requirement of the service, taking 1 / 2 of the round trip delay requirement of the service as the uplink delay requirement of the service, for example, when there is no delay budget to be mapped by the first QoS identifier that is equal to 1 / 2 round trip delay requirement, the first QoS request includes an uplink delay budget and a first QoS identifier, the value of the uplink delay budget is equal to 1 / 2 round trip delay requirement, and the downlink delay budget to be mapped by the first QoS identifier is not equal to 1 / 2 round trip delay requirement, the first communication device takes 1 / 2 round trip delay requirement as the value of the uplink delay budget of the first QoS request, because the priority of the uplink delay budget is higher than the first QoS identifier.

[0323] In one embodiment, the first QoS identifier of the first QoS request is mapped to the downlink delay requirement of the service, with 1 / 2 of the round trip delay requirement of the service being the downlink delay requirement of the service. For example, when there is no delay budget to map the first QoS identifier that is equal to 1 / 2 the round trip delay requirement, the first QoS request includes the first QoS identifier, so that 1 / 2 the round trip delay requirement is taken as the value of the uplink delay budget of the first QoS request.
