[0113] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0114] In some embodiments, the 5G QoS model is based on Quality of Service (QoS) flows. The 5G QoS model supports QoS flows that require a guaranteed bit rate (i.e., Guaranteed Bit Rate Quality of Service (GBR) QoS flows) and QoS flows that do not require a guaranteed bit rate (non-GBR QoS flows). The 5G QoS model also supports reflective QoS.

[0115] In some embodiments, a QoS flow is the finest granularity of QoS differentiation within a Packet Data Unit (PDU) session. A QoS Flow Identifier (QFI) is used to identify a QoS flow in a 5G system. User plane services with the same QFI within a PDU session receive the same service forwarding treatment (e.g., scheduling, admission thresholds). The QFI is carried in the encapsulation header on N3 (and N9), i.e., there is no change to the e2e packet header. The QFI applies to all PDU session types. The QFI should be unique within a PDU session. The QFI can be dynamically assigned or equal to the 5G QoS Identifier (5QI).

[0116] In some embodiments, within 5GS, QoS flows are controlled by a Session Management Function (SMF) and may be pre-configured or established through a PDU session establishment procedure or a PDU session modification procedure.

[0117] In some embodiments, any QoS flow is characterized by at least one of the following:

[0118] QoS profile provided by the SMF to the access network (AN) via the access and mobility management function (AMF) over the N2 reference point or pre-configured in the AN;

[0119] One or more QoS rules and optional QoS flow-level QoS parameters associated with these QoS rules, which may be provided to the UE by the SMF via the AMF over the N1 reference point and / or derived by the UE by applying reflective QoS control;

[0120] One or more uplink (UL) and downlink (DL) packet detection rules (PDR) provided by the SMF to the user plane function (UPF).

[0121] In some embodiments, in 5GS, a QoS flow associated with a default QoS rule needs to be established for the PDU session and maintained throughout the life cycle of the PDU session. This QoS flow should be a non-GBR QoS flow.

[0122] In some embodiments, a QoS flow is associated with QoS requirements specified by QoS parameters and QoS characteristics.

[0123] In some embodiments, the QoS flow associated with the default QoS rule provides connectivity for the UE throughout the lifecycle of the PDU session.Possible interworking with EPS prompts the suggestion that this QoS flow be of non-GBR type.

[0124] In some embodiments, QoS flows can be enabled through PDU set-based QoS processing. For such QoS flows, the PDU set QoS parameters are determined by the PCF and provided to the NG-RAN by the SMF as part of the QoS profile.

[0125] In some embodiments, a QoS flow can be "GBR" or "non-GBR", depending on its QoS profile. The QoS profile of a QoS flow is sent to the (R)AN and contains QoS parameters of at least one of the following:

[0126] For each QoS flow, the QoS profile should include QoS parameters: 5QI and Allocation and Retention Priority (ARP);

[0127] For each QoS flow, the QoS profile may also include QoS parameters: PDU set QoS parameters;

[0128] For each non-GBR QoS flow only, the QoS profile may also include QoS parameters: Reflective QoS Attributes (RQA);

[0129] For each GBR QoS flow only, the QoS profile shall also include the QoS parameters: Guaranteed Flow Bit Rate (GFBR) - UL and DL, and Maximum Flow Bit Rate (MFBR) - UL and DL;

[0130] In case of GBR-only QoS flows, the QoS profile may also include one or more QoS parameters: Notification Control and Maximum Packet Loss Rate - UL and DL.

[0131] In some embodiments, the maximum packet loss rate (UL, DL) is only provided to GBR QoS flows belonging to voice media.

[0132] In some embodiments, each QoS profile has a corresponding QoS flow identifier (QFI), which is not included in the QoS profile (also referred to as a profile) itself.

[0133] In some embodiments, the use of dynamically assigned 5QIs for QoS flows also requires signaling of the full 5G QoS features as part of the QoS profile.

[0134] In some embodiments, when standardized or pre-configured 5QI is used for QoS flows, some of the 5G QoS features may be part of the QoS profile.

[0135] In some embodiments, the UE performs classification and marking of UL user plane traffic based on QoS rules, i.e., UL traffic is associated with a QoS flow. These QoS rules can be explicitly provided to the UE (i.e., explicit signaling QoS rules using the PDU session establishment or modification process), pre-configured in the UE, or implicitly derived by the UE by applying reflective QoS. The QoS rules contain the QFI, packet filter set, and priority value of the associated QoS flow. The explicit signaling QoS rules contain a QoS rule identifier, which is unique within a PDU session and is generated by the SMF.

[0136] In some embodiments, there may be multiple QoS rules associated with the same QoS flow (ie, associated with the same QFI).

[0137] In some embodiments, when the UE informs the network the number of packet filters supported by the signalling QoS rules of a PDU session (during the PDU session establishment procedure or after the first inter-system change from EPS to 5GS for a PDU session established in EPS and transported from EPS with N26 interface, using the PDU session modification procedure), the SMF shall ensure that the sum of the packet filters used by all signalling QoS rules of the PDU session does not exceed the number indicated by the UE.

[0138] In some embodiments, it is specified how the UE evaluates UL packets according to the packet filters set in the QoS rules.

[0139] In some embodiments, for an unstructured type of PDU session, the default QoS rule does not include a packet filter set. In this case, the default QoS rule defines the processing of all packets in the PDU session.

[0140] In some embodiments, as long as the default QoS rule does not contain a packet filter set or contains a packet filter set that allows all UL packets, Reflective QoS should not be applied to the QoS flow associated with the default QoS rule and an RQA should not be sent for this QoS flow.

[0141] In some embodiments, a Mobile gNB with Wireless Access Backhaul (MWAB) is a mobile base station capable of acting as a gNB for other UEs and providing access to the 5G network. This means providing UEs with New Radio (NR) access links and wirelessly connecting to the 5GC (using NR) via an Internet Protocol (IP) connection provided by Packet Data Unit (PDU) or Protocol Data Unit (PDU) sessions established via an NG-RAN cell, on which the mobile gNB may reside. The PDU sessions are provided by either a terrestrial or non-terrestrial network. Such a mobile gNB can be installed in a moving vehicle and serve UEs that can be located inside or outside the vehicle (or entering or exiting the vehicle).

[0142] In some embodiments, the MWAB-gNB is the base station portion of the MWAB.

[0143] In some embodiments, the MWAB-UE is the terminal portion of the NWAB.

[0144] Please refer to Figure 1b, which shows an example of the architecture of a non-roaming scenario of a 5G system.

[0145] In some embodiments, based on the definition of MWAB, MWAB provides wireless connection to 5GC through IP connection provided by PDU session, and both N2 interface and N3 interface are carried on the PDU session between MWAB-UE and 5GC.

[0146] In some embodiments, for the N2 interface and the N3 interface, at least one PDU session is established between the MWAB-UE and the 5GC:

[0147] If the serving AMF and serving UPF of the MWAB-UE are in the same data network name (DNN), N2 and N3 use a single PDU session; otherwise, the PDU session of N2 and the PDU session of N3 are separate.

[0148] As shown in Figure 1c, UE PDU sessions are backhauled over N3 via MWAB-UE PDU sessions, so they need to share common features such as single network slice selection assistance information (S-NSSAI), DNN, PDU session type, and session and service continuity (SSC) mode. In addition, UE Quality of Service (QoS) flows and MWAB-UE QoS flows must be mapped to each other for transmission to / from the 5GC via the MWAB-UE Uu interface and UE Uu interface.

[0222] In order to better understand the embodiments of the present disclosure, some exemplary embodiments are further described below:

[0223] In some embodiments, when the MWAB-gNB determines that the UE needs to support a new QoS flow (and / or PDU session), the MWAB-gNB binds the UE QoS flow to a b / h PDU session (i.e., N3 backhaul PDU session) based on the QoS flow characteristics.

[0224] In some embodiments, if there is an existing b / h PDU session that matches the QoS flow characteristics, then that b / h PDU session is selected and the UE PDU session is bound to that b / h PDU session.

[0225] In some embodiments, if an existing b / h PDU session does not match the UE QoS flow characteristics, a new MWAB-UE PDU session is established based on the QoS flow characteristics. Alternatively, the existing b / h PDU session is modified to accommodate the new QoS flow.

[0226] Example 1:

[0227] Referring to FIG. 6 , a communication method (which may be an N3 backhaul PDU session establishment process) is shown, the method including:

[0228] Step S6101: A PDU session is established or modified for the UE, and this causes the MWAB-gNB to receive a new SM context for the PDU session including at least the QoS flow from the SMF.

[0229] Step S6102: The MWAB-gNB requests the MWAB-UE to perform modification of the b / h PDU session using specific 5QI and QoS parameters suitable for processing the service data flow (SDF) of the DL / UL service identified by the Internet Protocol (IP) address and Differentiated Services Code Point (DSCP) value of the MWAB-gNB / UE-UPF.

[0230] Step S6103: The MWAB-UE modifies the b / h PDU session as instructed. The MWAB SMF performs MWAB UE QoS flow binding (corresponding mapping relationship) according to the QoS parameters of the UE QoS flow.

[0231] In some embodiments, for UL traffic, the MWAB UE uses the QoS parameters included in the QoS profile associated with the UL UE QoS flow as the QoS parameters of the UL MWAB UE QoS flow obtained from the MWAB gNB.

[0232] In some embodiments, for DL ​​traffic, the MWAB UPF uses the QoS parameters included in the QoS profile associated with the DL UE QoS flow as the QoS parameters of the DL MWAB UE QoS flow obtained from the UE UPF.

[0233] Step S6104: The UPF of the b / h PDU session can now correctly process the DL traffic from the UE UPF.

[0234] Step S6105: The MWAB-UE confirms the correct modification of the b / h PDU session.

[0235] Step S6106: MWAB-gNB can complete the establishment of the PDU session.

[0236] Step S6107: The data of the UE PDU session can be sent / received with the correct QoS.
