4. Policy Control Function (PCF) network element

PCF supports a unified policy framework to manage network behavior, provides policy rules for network entities to implement, and accesses subscription information of the Unified Data Warehouse (UDR).

5. Unified Data Repository (UDR) network element

UDR is used for UDM to store subscription data or read subscription data and PCF to store policy data or read policy data.

6. User Plane Function (UPF) network element.

UPF serves as the interconnection point between Mobile Infrastructure (for example: RAN) and data network DN (DataNetwork), completing the encapsulation and decapsulation of the GTP-U (GRPS Tunneling Protocol) protocol on UP. Usually, UPF is used as the Session Anchor Point (Protocol Data Unit, PDU) for mobility within Radio Access Technologies (RAT) or between RATs, including to gNB (NG- RAN node) sends one or more end mark packets (End Marker Packets, EMP).

7. Packet Data Unit (PDU) session

The PDU session is a logical connection between the user equipment UE and the designated DN (Data Network, data network), providing the UE with a user plane connection to the DN. 5GS supports 3 PDU session types, including IP-based PDU session type, Ethernet-type PDU session type and unstructured PDU session type.

Relevant content of the embodiments of the present disclosure is introduced below.

In a PDU session, 5G QoS management is achieved by creating different QoS flows. The QoS flow is the finest granularity of QoS differentiation in the PDU session. Different Qos flows correspond to different QoS forwarding processing. 5G QoS flows are divided into two categories: QoS flows with traffic bit rate (GBR QoS flow) and QoS flows that do not require guaranteed traffic bit rate (Non-GBR QoS flow). In 5GS, QoS flows are controlled by SMF, which can be pre-configured or established through the PDU session establishment procedure or the PDU session modification procedure.

SDF is mapped into QoS flows according to certain rules. The rules from SDF to QoS flows are QoS rules and PDR, which are the rules for terminals and network devices to classify and map upstream/downstream data packets. In the downlink direction, UPF performs specific classification mapping tasks based on the PDR issued by the SMF. If there is no matching PDR, UPF will discard the downlink data packet. In the uplink direction, the UE is responsible for performing specific classification and mapping. Classification and mapping can be performed based on the QoS rules issued by the network device, the QoS rules pre-configured in the UE, and the QoS rules derived by the UE itself. Among them, the QoS rules issued by the network device QoS rules are called signaling QoS rules (Signalled QoS rules). QoS rules derived by the UE itself are called UE-derived QoS Rules. The QoS rules derived by the UE based on the received downlink user plane data are used for Upstream data packets are classified and mapped, and the corresponding concept is called reflective QoS.

QoS rules include the QFI, packet filter set and priority value of the relevant QoS flow, during the PDU session establishment process, or for a PDU session established in the EPS and transferred from the EPS to 5GS through the N26 interface, during the first inter-system During the post-change use PDU session modification process, when the UE notifies the network about the number of packet filters supported by the signaling QoS rules of the PDU session, the SMF shall ensure that the packet filters used by all signaling QoS rules of the PDU session are The total does not exceed the number indicated by the UE.

The maximum number of supported packet filters is specified in the related art. The purpose of the maximum number of supported packet filters information element is that when the PDU session type is "IPv4", "IPv6", "IPv4v6" or "Ethernet" , the UE indicates to the network the maximum number of packet filters related to signaling QoS rules that the PDU session being established can support.

In summary, under the signaling QoS rules, the UE can report to the network the maximum number of packet filters related to the signaling QoS rules that the established PDU session can support, which can ensure that the network equipment does not use signaling that the terminal does not support. The number of packet filters of the derivation QoS rules. Under the derivation QoS rules, the network does not know the maximum number of packet filters supported by the UE's derivation QoS rules. The network can apply packets of reflective QoS rules that the UE cannot support. The number of filters, then the UE's reflective QoS cannot be fully supported. For example, under the derivation QoS rule, the maximum number of packet filters supported by the UE is 10. The network device applies 11 packet filters without knowing the maximum number, resulting in the UE not being able to fully support it.

The disclosed method is used to solve the technical problem of "how does the network know the maximum number of packet filters supported by the UE's derived QoS rules?" The network can know the maximum number of packet filters supported by the UE's derived QoS rules, thereby The network will not apply reflective QoS with packet filter numbers that are not supported by the UE.

1016b. UPF provides N4 session modification response to SMF.

1016c. SMF registers with UDM.

On the one hand, if the request type in step 1003 represents neither "Emergency Request" nor "Existing Emergency PDU Session", and if SMF has not registered for this PDU session, then SMF will use Nudm_UECM_Registration (including SUPI, DNN, HPLMN's S-SSAI, PDU session ID, SMF identity, service node PLMNID, NID) register with UDM for a specific PDU session.

Among them, UDM stores the following information: SUPI, SMF identity and related DNN, HPLMN's S-NSSAI, PDU session ID and service network, including PLMN ID, NID. UDM can further store this information in UDR through Nudr_DM_Update, which includes SUPI, subscription data, and UE context in SMF data.

1017. SMF sends Nsmf_PDUSession_UpdateSMContext response to AMF.

1018. SMF sends Nsmf_PDUSession_SMContextStatusNotify release to AMF.

Specifically, if in the program, at any time after step 1005, the PDU session establishment is unsuccessful, SMF releases and notifies AMF by calling Nsmf_PDUSession_SMContextStatusNotify. The SMF also releases any created N4 sessions, any PDU session addresses, and releases the association with the PCF, in which case step 1019 is skipped.

1019. SMF configures the IPv6 address for the UE.

Specifically, when the PDU session type is IPv6 or IPv4v6, SMF generates an IPv6 route and sends it to the UE.

1020. When the trigger that 5GS bridge/router information is available is activated, then SMF can initiate SM policy association modification.

1021. SMF unsubscribes session management subscription data.

Specifically, if the PDU session establishment fails after step 1004, the SMF unsubscribes and modifies the session management subscription data. If the MF no longer processes the PDU session for the UE, the UDM can unsubscribe from the UDR modification notification through Nudr_DM_Unsubscribe.
