- the QoS policy may include the following QoS parameters of this QoS flow: 5G QoS Identifier (5G QoS Identifier, 5QI), Allocation and Retention Priority (ARP), and bit rate requirements.
- QoS rules QoS rules
- PDR Packet Detection Rule
- the UPF matches the received data packets according to the priority of the downstream packet filter set in the PDR sent by the SMF from high to low. If a downstream matching PDR is found, the corresponding QFI is encapsulated into the header according to the matching result. The RAN maps the data packets to the corresponding DRBs according to the QFI. If no downstream PDR is matched, the UPF discards the packet.
- the UE matches the data packets to be sent according to the priority of the uplink packet filter set in the QoS rule (QoS rule) from high to low.
- the UE uses the QFI in the corresponding QoS rule to bind the uplink message to the QoS flow, and further binds the QoS flow to the corresponding data radio bearer (Data Radio Bearer, DRB). If there is no match, the UE discards the data packet. However, there is a default QoS rule in the UE, and the set packet filter can allow all data packets, in order to match all data packets and prevent the loss of uplink data packets.
- DRB Data Radio Bearer
- QoS parameters are usually used to characterize QoS flows.
- QoS flows are mainly divided into Guaranteed Bit Rate (Guaranteed Bit Rate) QoS flows and non-GBR QoS (non-GBR QoS) flows.
- Guaranteed Bit Rate Guaranteed Bit Rate
- non-GBR QoS non-GBR QoS

- GFBR Guaranteed Flow Bit Rate
- MFBR Maximum Flow Bit Rate
- AMBR Aggregate Maximum Bit Rate
- 5QI can be understood as a scalar pointing to a variety of QoS characteristic values, divided into three types: standardized 5QI, pre-configured 5QI, and dynamically allocated 5QI.
- standardized 5QI when the core network provides the QoS flow configuration of the QoS flow to the base station, not only the 5QI but also the complete set of QoS characteristic values corresponding to the 5QI should be included in the QoS flow configuration.
- the core network only needs to provide the 5QI, and the base station can parse out the set of various QoS feature values corresponding to the 5QI.
- the core network is also allowed to provide one or more QoS characteristic values different from the standardized or preconfigured QoS characteristic values for modifying the corresponding standardized or preconfigured QoS characteristic values.
- the standardized 5QI is mainly used for more general and frequently used services.
- the dynamically allocated 5QI is mainly used for less general services that cannot be satisfied by the standardized 5QI.
- ARP allocation and retention priority including priority level, resource preemption capability, and whether resources are allowed to be preempted, are used to determine whether to allow the establishment, modification, and switching of QoS flows when resources are limited.
- ARP is also used to preempt the resources of existing QoS flows when resources are limited. For example, high-priority QoS flows can preempt low-priority QoS flows.
- RQA instructs some QoS flows carried by SDF to apply reverse mapping QoS.
- GFBR instructs the base station to ensure that enough resources are reserved for the code rate of a QoS stream transmission within the average time window.
- MFBR is limited to the maximum bit rate for QoS streaming.
- the QoS notification control indicates that when the base station cannot guarantee the GFBR of the QoS flow, continue to try to maintain the QoS flow and notify the core network that the QoS requirement cannot be guaranteed, the NG-RAN tries to re-guarantee, and informs the SMF that the QoS requirement is re-guaranteed.
- Session AMBR controls the total code rate of all non-GBR QoS flows in a PDU session.
- UE-AMBR controls the total code rate of all non-GBR QoS flows of a UE.

- the session establishment process 300 may include:
- the UE sends a session establishment request message to the AMF, including a session identifier, a session type (initial session establishment, EPS to 5GS handover, Non-3GPP to 3GPP handover, request for emergency services), SCC mode, DNN, S-NSSAI and other parameters.
- a session identifier including a session identifier, a session type (initial session establishment, EPS to 5GS handover, Non-3GPP to 3GPP handover, request for emergency services), SCC mode, DNN, S-NSSAI and other parameters.
- the AMF selects an appropriate SMF according to the DNN, S-NSSAI and subscription data.
- the AMF invokes the session service of the selected SMF to trigger session establishment.
- the SMF obtains session subscription data from the UDM, such as the SCC mode (mode) allowed by the user, the session type, and the Session-AMBR of the session.
- the SCC mode mode
- the Session-AMBR Session-AMBR
- the SMF selects a PCF for the session.
- the SMF establishes a policy connection with the PCF to obtain the PCC rule.

- the SMF sends a session establishment accept message to the UE through the AMF and the AN.
- the SMF registers with the UDM, and the UDM records the SMF ID corresponding to the dialog.
- the SMF allocates an IPv6 prefix to the UE, and sends the prefix to the UE through the user plane.
- the QoS flow is for a single UE, that is, the network can allocate resources to each UE to ensure its transmission quality.
- the network needs to ensure the overall transmission quality of a group of nodes, not just the quality of a single node.
- the parameters involved in the session establishment process 300 cannot instruct the network to guarantee the quality of service of a group of nodes, nor can it implement flexible cross-UE resource scheduling according to the communication quality and differences in computing capabilities between different nodes in the group to ensure a Group nodes efficiently complete a training iteration.
- the UE needs a very high transmission rate for the transmission of AI model parameters. Therefore, in order to ensure the service quality of a group of nodes by the network, and at the same time, according to the difference in communication quality and computing power between different nodes in the group, to achieve flexible Cross-UE resource scheduling ensures that a group of nodes efficiently completes one training iteration.
- This application introduces a new parameter, namely Group-GBR/MBR (Group-GBR/MBR).
- Group-GBR represents a group of nodes that are performing the same task, and the network guarantees the transmission rate for it, that is, the sum of the GBRs of all QoS flows for all nodes in the group to perform the same task.
