[0125] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0126] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only.

[0127] 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).

[0128] In some embodiments, a PDU set in an XRM service, in a 5G system (5GS), a quality of service (QoS) flow is the minimum granularity for QoS differentiation in a PDU session. 5G QoS characteristics are determined by a 5G QoS indicator (5QI), which means that each packet in a QoS flow is processed according to the same QoS requirements.

[0129] For XRM services, a set of data packets is used to carry the payload of a PDU set (e.g., a frame, video slice / texture). At the media layer, the packets in the PDU set are decoded / processed as a whole. For example, a frame can only be decoded if all or a certain number of packets carrying the frame are successfully sent. For example, a frame in a group of pictures (GOP) can only be decoded by the client if all frames associated with the frame are successfully received. Therefore, the packets in the PDU set have an inherent correlation at the media layer. If the correlation between the packets in the PDU set is not taken into account, the 5GS may perform less efficient scheduling. For example, the 5GS may randomly discard packets but try to send other packets of the same PDU set that are useless to the client, thereby wasting radio resources.

[0130] In some embodiments, PDU Set integrated packet processing defines the following PDU Set QoS parameters to support PDU Set processing:

[0131] -PDU Set Error Rate (PSER): PSER defines an upper limit on the ratio of the number of PDU sets that were not successfully received to the total number of PDU sets sent to the receiver within a measurement window. PSER defines an upper limit on the proportion of PDU sets processed by the transmitter of the link layer protocol (such as radio link control (RLC)) that were not successfully passed to the upper layer (such as packet data convergence protocol (PDCP)) by the corresponding receiver. Therefore, PSER defines an upper limit for non-congestion related packet loss rate. The purpose of PSER is to allow appropriate link layer protocol configuration (such as RLC and hybrid automatic repeat request (HARQ)). For each 5QI, the value of PSER is the same in the uplink (UL) and downlink (DL). If any PDU in a PDU Set is not successfully transmitted, the PDU Set is considered to be erroneous.

[0132] -PDU Set Delay Budget (PSDB): The PSDB defines the upper bound on the transmission delay of a PDU set between the terminal and the N6 termination point at the user plane function (UPF). This is the time from the receipt of the first PDU to the successful delivery of the last arriving PDU. The PSDB applies to downlink PDU sets received by the UPF over the N6 interface and to downlink PDU sets sent by the terminal. For a given 5QI, the PSDB value is the same for both uplink (UL) and downlink (DL).

[0133] PDU set integrated handling indication (PSIHI): Indicates whether all PDUs of a PDU set are required to use the PDU set by the application layer.

[0134] In some embodiments, as shown in Figure 1B , a split architecture of access network equipment is implemented, in which the access network equipment (gNB)-centralized unit (CU)-control plane (CP) is responsible for radio resource control (RRC) and packet data convergence protocol (PDCP) control plane functions, the gNB-CU-user plane (UP) is responsible for general packet radio service tunneling protocol for the user plane (GTP-U), service data adaptation protocol (SDAP), and PDCP user plane functions, and the gNB-distributed unit (DU) is responsible for radio link control (RLC), media access control (MAC), and physical layer (PHY) functions.

[0135] In some embodiments, the gNB CU-CP and gNB CU-UP are connected via the E1 interface. The gNB CU-CP is connected to the gNB DU via the control plane corresponding to the F1 interface, i.e., F1-C. The gNB CU-UP is connected to the gNB DU via the user plane corresponding to the F1 interface, i.e., F1-U.

[0136] In some embodiments, in a CU-DU split architecture, the PDU set QoS parameters are sent by the gNB-CU-CP to the gNB-CU-UP and gNB-DU. The gNB-CU-UP and gNB-DU process the uplink and downlink data of the XRM service based on the PDU set QoS parameters.

[0137] In the related art, the inability of access network equipment to determine when to start or stop executing operations based on PDU set processing is a problem that needs to be solved urgently.

[0138] Based on this, embodiments of the present disclosure provide an information processing method, apparatus, and storage medium, wherein the method, executed by an access network device, includes: determining first information; wherein the first information includes at least one of the following: first indication information from a terminal; second indication information from a core network device; configuration status information of the access network device; and determining, based on the first information, to start executing an operation based on PDU set processing, or determining, based on the first information, to stop executing an operation based on PDU set processing. Thus, the access network device can determine to start or stop executing an operation based on PDU set processing based on the first information, thereby improving the utilization of device resources while ensuring the user's XRM service experience.

[0492] In some embodiments, in a CU-DU split architecture, the first node (gNB-CU-CP) of the access network device needs to notify the second node (gNB-DU or gNB-CU-UP) of processing information related to the PDU set. Alternatively, in a DC scenario, the first node (MN) of the access network device needs to notify the second node (SN) of the access network device of processing information related to the PDU set.

[0493] - Method 1: The gNB-DU or gNB-CU-UP decides whether to start or stop PDU set-based processing. The PDU set-related processing information is the supported PDU set processing capabilities reported by the terminal.

[0494] - Method 2: The gNB-CU-CP decides whether to start or stop PDU set-based processing. The PDU set-related processing information is used to indicate whether to start or stop PDU set-based processing.

[0530] - Based on PDU set QoS parameters, schedule resources and / or perform packet loss to ensure that the corresponding PDU set QoS requirements are met and improve resource utilization. The PDU set QoS parameters include but are not limited to: PSER, PSDB, PHISI.

[0531] 102. In a CU-DU separation architecture, the gNB-CU-CP (or gNB-CU) sends a F1AP message to the gNB-DU. The F1AP message includes PDU set processing capability information. The gNB-DU receives the message and starts or stops PDU set-based processing based on the PDU set processing capability information.

[0532] Among them, the processing based on PDU set is consistent with the description in 101 and will not be repeated here.

[0533] In some embodiments, the F1AP message is a terminal context setup request message (UE context setup request) or a terminal context modification request message (UE context modification request), but is not limited thereto.

[0534] 103. The gNB-CU-CP sends an E1AP message to the gNB-CU-UP. The E1AP message includes PDU set processing capability information. The gNB-CU-UP receives the message and starts or stops PDU set-based processing based on the PDU set processing capability information.

[0535] The processing based on the PDU set is consistent with that described in step 101 and will not be repeated here.

[0536] In some embodiments, the E1AP message is a bearer context setup request message (bearer context setup request) or a bearer context modification request message (bearer context modification request), but is not limited thereto.

[0537] 104. If the gNB-DU detects congestion and the UE supports PDU set processing, the gNB-DU sends a MAC CE to the UE, where the MAC CE is used to activate PSI-based discard.

[0538] If the gNB-DU detects that congestion has ceased, or the UE does not support PDU set processing, the gNB-DU sends a MAC CE to the UE to deactivate PSI-based discard.

[0539] In another exemplary embodiment, as shown in Figure 6B, the first node of the access network device is gNB-CU-CP, the second node of the access network device is gNB-DU or gNB-CU-UP, and the core network device is AMF.

[0540] 200. The access network device receives PDU set QoS parameters from the core network device. If supported and agreed, the access network device performs PDU set-based processing based on the PDU set QoS parameters. In the CU-DU separation architecture, the gNB-CU-CP sends the PDU set QoS parameters to the gNB-DU and gNB-CU-UP. If supported and agreed, the gNB-DU and gNB-CU-UP perform PDU set-based processing based on the PDU set QoS parameters.

[0541] 201a. The terminal sends terminal auxiliary information (such as the first indication information described in some of the above embodiments) to the access network device (in the CU-DU separation scenario, i.e., gNB-CU-CP), wherein the terminal auxiliary information includes PDU set processing capability information, which is used to indicate whether the UE supports PDU set processing.

[0542] 201b, the core network device (such as AMF) sends an NGAP message (such as the second indication information described in some of the above embodiments) to the access network device (for example, a PDU session resource modification request message, a context modification request message, etc.), wherein the NGAP includes information for requesting to stop PDU set-based processing (also referred to as: disable or deactivate PDU set handling or PDU set based handling, which means to stop (or terminate) PDU set-based processing, and PDU set processing may also include "PDU set-based QoS handling").

[0543] The information requesting to stop processing based on the PDU set includes at least one of the following information:

[0544] - Instruction requesting to stop processing based on PDU set;

[0545] -QoS flow list (including at least one QoS flow ID), used to indicate the request to stop the QoS flow based on PDU set processing;

[0546] 201c, the access network device decides to stop the processing based on the PDU set. For example, when the access network device is highly loaded or the energy consumption is too high, the access network device may stop the processing based on the PDU set.

[0547] 202. In a CU-DU split architecture, if the gNB-CU determines to stop PDU set-based handling, the gNB-CU sends a F1AP message (e.g., a Terminal Context Modification Request message) to the gNB-DU. The F1AP message includes information indicating the stop of PDU set-based handling, and the gNB-DU stops PDU set-based handling based on the information.

[0548] 202. In a CU-DU separation architecture, if the gNB-CU-CP determines to stop PDU set-based handling, the gNB-CU-CP sends an E1AP message (e.g., a Bearer Context Modification Request message) to the gNB-CU-UP. The E1AP message includes information indicating the stop of PDU set-based handling, and the gNB-CU-UP stops PDU set-based handling based on the information.

[0549] For a detailed description of the processing based on the PDU set, please refer to Example 1.

[0550] The information for instructing to stop the PDU set-based processing includes at least one of the following information:

[0551] - Instruction requesting to stop processing based on PDU set;

[0552] -QoS flow list (including at least one QoS flow ID), used to indicate the request to stop the QoS flow based on PDU set processing;

[0553] -DRB list (including at least one DRB ID), used to indicate the DRB that requests to stop PDU set-based processing

[0554] In another exemplary embodiment, as shown in Figure 6C, the first node of the access network device is gNB-CU-CP, the second node of the access network device is gNB-DU or gNB-CU-UP, and the core network device is AMF.

[0555] 300, same as described in 200.

[0556] 301. If the access network device decides to stop PDU set-based processing, the access network device sends an NGAP message (such as the fourth indication information described in some of the above embodiments) to the core network device, such as a PDU session resource notify, wherein the NGAP message includes information for indicating the stop of PDU set-based processing.

[0557] The information for indicating the stopping of the PDU set-based processing includes at least one of the following information:

[0558] - Stop information based on PDU set processing;

[0559] -QoS flow list (including at least one QoS flow ID), used to indicate the QoS flow that has stopped processing based on the PDU set;

[0560] - Cause value, used to indicate the reason for stopping the PDU set-based processing.

[0561] The core network device receives the information and can start or stop marking the PDU set based on the information. (For example, if the access network device does not use PDU set-based processing, the UPF can avoid marking the PDU set, thereby reducing energy consumption and improving efficiency of the core network device.)
