[0123] To facilitate understanding of the embodiments of this application, extended reality (XR) related to this application will be described.

[0124] Extended reality (XR) refers to all combined real and virtual environments and human-computer interactions created by computer technology and wearable devices. It includes representative forms such as augmented reality (AR), mixed reality (MR), and virtual reality (VR), as well as the intersections between them. The levels of virtual worlds range from partial sensory input to fully immersive virtual reality. A key aspect of XR is the extension of human experience, especially experiences related to presence (represented by VR) and cognitive acquisition (represented by AR).

[0125] For VR services, uplink transmission primarily involves dense, small data packet transmissions. These packets can carry gesture and control information, serving as input and reference for downlink presentation data. Downlink transmission mainly consists of multimedia data transmissions such as video and audio. The timely reception and presentation of this multimedia data provides users with an immersive experience. Taking downlink video data as an example, video data can be modeled as video frames based on frame rate (Frames Per Second, FPS), with typical FPS values ​​of 60 or 120. These video frames arrive periodically or quasi-periodically based on a period determined by the FPS (1 / FPS second), and the size of the video frame changes dynamically. Each video frame is generally required to be successfully transmitted within 10ms over the air interface, with a transmission success rate of no less than 99%, or even 99.9%. Furthermore, downlink video data typically requires very high data rates, generally reaching tens or even hundreds of Mbps (typically 30 / 45 Mbps).

[0126] For AR services, in addition to the dense small data packet transmission mentioned above, uplink may also transmit multimedia data such as video, audio, and scene images. Its service characteristics are similar to those of downlink, with relatively low data rates, such as at most tens of Mbps (typically 10 / 20 Mbps). The time limit for air interface transmission can also be relaxed, for example, each video frame is generally required to be successfully transmitted within 30ms. The downlink data transmission characteristics are basically consistent with those of VR services.

[0127] To facilitate understanding of the embodiments of this application, the Quality of Service (QoS) rules related to this application are explained.

[0128] In related technologies, the UE classifies and labels uplink (UL) user plane data flows based on QoS rules, that is, it associates UL data flows with QoS flows. QoS rules can be explicitly provided to the UE (i.e., explicitly indicated by signaling during Protocol Data Unit (PDU) session establishment / modification), or they can be pre-configured in the UE or implicitly derived by the UE. A QoS rule includes a Quality of Service Flow Indicator (QoSflowID, QFI) associated with the QoS flow, a Packet Filter Set, and a priority value. A QoS rule in an explicit signaling context contains a QoS rule identifier, which is unique within the PDU session and generated by the SMF.

[0129] In some scenarios, multiple QoS rules can be associated with the same QoS flow (e.g., having the same QFI).

[0130] In some scenarios, a default QoS rule needs to be sent to the UE each time a PDU session is established, and this rule is associated with the QoSFlow. For Internet Protocol (IP) type PDU sessions or Ethernet type PDU sessions, the default QoS rule is the only QoS rule in a PDU session that may contain a packet filtering set that allows all UL packets. In this case, the highest priority QoS rule should be used.

[0131] In some scenarios, the classification and identification of data streams are based on Packet Filters.

[0132] In some scenarios, each packet filter is of variable length and consists of the packet filtering direction (2 bits), the packet filtering identifier (4 bits), the length of the packet filtering content (1 bit), and the packet filtering content itself (variable number of bytes).

[0133] The packet filtering direction field indicates the data flow direction to which the filter can be applied.

[0134] The packet filter identifier field is used to identify each packet filter in the QoS rule. When the terminal requests "Create a new QoS rule", "Modify an existing QoS rule and replace all packet filters", or "Modify an existing QoS rule and add a packet filter", the packet filter identifier value is set to 0.

[0135] The length field of the packet filter content field indicates the binary encoded length of the packet filter content field. The first bit in the transmission order is the most important bit.

[0136] The packet filter content field is variable in size and contains a variable number of packet filter components (at least one). Each packet filter component should be encoded as a sequence consisting of a 1-byte packet filter component type identifier and a fixed-length packet filter component value field. The packet filter component type identifier is transmitted first.

[0137] In some scenarios, the packet filtering component type identifier can identify the following packet filtering component types:

[0138] Match-all type;

[0139] IPv4 remote address type;

[0140] IPv4 local address type;

[0141] IPv6 remote address / prefix length type;

[0142] IPv6 local address / prefix length type;

[0143] Protocol identifier / Next header type;

[0144] Single local port type;

[0145] Local port range type;

[0146] Single remote port type;

[0147] Remote port range type;

[0148] Security parameter index type;

[0149] Type of service / Traffic class type;

[0150] Flow label type;

[0151] Destination MAC address type;

[0152] Source MAC address type;

[0153] 802.1Q Customer Tag (C-TAG) Virtual Local Area Network Identifier (VID) type;

[0154] 802.1Q Service Tag (S-TAG) VID type;

[0155] 802.1Q C-TAG Priority Code Point (PCP) / DropEligible Indicator (DEI) type;

[0156] 802.1Q S-TAG PCP / DEI type;

[0157] Ethertype;

[0158] Destination MAC address range type;

[0159] Source MAC address range type.

[0160] In some scenarios, each package filter component type should not appear more than once within each package filter.

[0161] In some scenarios, QoS rule matching can be performed at the granularity of packet set (PDU set).

[0162] To facilitate understanding of the embodiments of this application, the QoS rule detection mechanism related to this application will be described.

[0163] The UE can perform the following verifications on the authorized QoS rules and the authorized QoS flow description provided in the PDU session acceptance message for different types of errors:

[0164] 1. Packet filter semantic error.

[0165] When a packet filter consists of conflicting packet filter components, it will render the packet filter ineffective, meaning no IP packets will be applicable to this packet filter. If the QoS rule is the default QoS rule, the UE should initiate a PDU session release procedure, sending a PDU session release request message that includes the 5G Session Management (5GSM) cause value cause#44 "semantic error in packet filter(s)". Otherwise, the UE sends a PDU session modification request message to delete the QoS rule with 5GSM cause#44.

[0166] 2. Packet filter syntax error:

[0167] When the rule operation is "create a new QoS rule", two or more packet filters in the resulting QoS rule will have the same packet filter identifier.

[0168] When other types of syntax errors exist in the encoding of the packet filter, such as when the packet filter component identifier uses a reserved value.

[0169] If the QoS rule is the default QoS rule, the UE should initiate a PDU session release procedure, sending a PDU session release REQUEST message with 5GSM cause#45 "syntax errors in packet filter(s)". Otherwise, the UE sends a PDU session modification REQUEST message to delete the QoS rule with 5GSM cause#45.

[0170] After the introduction of XR technology, it is necessary to identify different sub-streams of the data stream (for example, when streams of different media types are transmitted in the same IP 5-tuple, the different media types of streams can be called a sub-stream), which may require enhancement of packet filters by adding some new components. These new packet filters are not recognized by UEs prior to Release 19, which will cause syntax errors. Under the current method, once a QoS rule with a syntax error is encountered, the UE will request the network side to delete the QoS rule and its corresponding communication resources.

[0171] For XR data streams, specific QoS rules are typically used to match PDU sets. Deleting these specific QoS rules will prevent the UE from matching the QoS rules based on the PDU set, severely impacting the user experience.

[0172] Therefore, how to configure QoS rules to ensure the transmission of XR data streams is an urgent problem to be solved.

[0173] Figure 2 This is a schematic diagram illustrating a wireless communication method provided in an embodiment of this application. Figure 2 As shown, the method 200 includes at least the following:

[0174] S210, the third communication device sends a first request message to the second communication device, wherein the first request message includes at least one of the following:

[0175] Fifth Service Data Flow (SDF) Template;

[0176] Sixth SDF template;

[0177] Fifth, Quality of Service (QoS);

[0178] The sixth QoS.

[0179] In some embodiments, the third communication device may be an application-related device, such as an application server, AF, etc.

[0180] Optionally, the first request information is used to request QoS and / or reserve resources for the AF session.

[0181] In some implementations, the fifth SDF template satisfies at least one of the following:

[0182] The fifth SDF template corresponds to the first data stream;

[0183] The fifth SDF template corresponds to the fifth QoS.

[0184] In some implementations, the sixth SDF template satisfies at least one of the following:

[0185] The sixth SDF template corresponds to the second data stream;

[0186] The sixth SDF template corresponds to the sixth QoS.

[0187] In some implementations, the fifth QoS satisfies at least one of the following:

[0188] The fifth QoS corresponds to the fifth SDF template;

[0189] The fifth QoS corresponds to the first data stream.

[0190] In some implementations, the sixth QoS satisfies at least one of the following:

[0191] The sixth QoS corresponds to the sixth SDF template;

[0192] The sixth QoS corresponds to the second data stream.

[0193] In some implementations, the second data stream includes at least one first data stream, or the at least one first data stream is multiplexed in the second data stream.

[0194] In some implementations, the second data stream may be a data stream transmitted between the terminal and a third communication function (e.g., AF). The second data stream includes at least one first data stream, which can be considered as a sub-data stream of the second data stream. Alternatively, at least one first data stream may be multiplexed in the second data stream, which can be considered as a multiplexed sub-data stream of the second data stream.

[0195] In some implementations, the second data stream includes multiple multiplexed sub-data streams. For example, when multiple media streams are multiplexed in the same IP 5-tuple, the first data stream can be its sub-data stream, such as a video stream, an audio stream, or other sub-data streams.

[0196] In some implementations, the terminal needs to identify different data streams, such as video streams and audio streams. The third communication device can request the corresponding SDF template and / or QoS based on the characteristics of the data stream to be identified, so that the network side can configure appropriate QoS rules to identify different streams.

[0197] As an example, suppose the second data stream includes two sub-data streams (e.g., a video stream and an audio stream). Let the sub-data stream containing the video stream be designated as first data stream-1, and the sub-data stream containing the audio stream be designated as first data stream-2. Then, the third communication device can use the following request method:

[0198] Method 1: The third communication device requests three QoS protocols (denoted as QoS#1, QoS#2, and QoS#3). Specifically: the second data stream corresponding to QoS#1 is identified by the IP 5-tuple, meaning the second communication device's SDF template equals the IP 5-tuple; the first data stream -1 corresponding to QoS#2 is identified by the IP 5-tuple plus SSRC1, meaning the second communication device's SDF template equals the IP 5-tuple plus SSRC1; and the first data stream -2 corresponding to QoS#3 is identified by the IP 5-tuple plus SSRC2, meaning the PCF's SDF template equals the IP 5-tuple plus SSRC2. QoS#1 is a PDU set-based QoS, while QoS#2 and QoS#3 are packet-based QoS. Based on this, the terminal can be configured with three filters by the network side: for example, Packet filter#1 includes the IP 5-tuple, Packet filter#2 includes the IP 5-tuple plus SSRC#1, and Packet filter#3 includes the IP 5-tuple plus SSRC#2.

[0199] Therefore, based on method 1, the third communication device can request the QoS of three flows, which enables the network side to generate three filters for the terminal, so that the terminal has at least one QoS filter based on the PDU set available (i.e., Packet filter #1), ensuring the smooth execution of XR services.

[0200] Method 2: The third communication device requests two QoS protocols (denoted as QoS#1 and QoS#2), where: the first data stream -1 corresponding to QoS#1 is identified by the IP 5-tuple + SSRC1; the first data stream -2 corresponding to QoS#2 is identified by the IP 5-tuple + SSRC2. Based on this, the terminal can be configured with two filters by the network side: Packet filter#1 includes the IP 5-tuple + SSRC#1, and Packet filter#2 includes the IP 5-tuple + SSRC#2.

[0201] The second data stream includes at least one first data stream, or the at least one first data stream is multiplexed in the second data stream.

[0202] In some implementations, the fifth SDF template includes at least one of the following:

[0203] The seventh SDF template corresponds to the first data stream;

[0204] The eighth SDF template corresponds to the second data stream.

[0205] In some implementations, the fifth QoS includes at least one of the following:

[0206] The seventh QoS corresponds to the first data stream;

[0207] The eighth QoS corresponds to the second data stream.

[0208] It should be noted that, in the embodiments of this application, the data stream corresponding to the SDF template can be understood as having the same characteristics as the corresponding data stream. Taking the first data stream as identified by the IP 5-tuple + SSRC1 as an example, if the fifth SDF template corresponds to the first data stream, it can be understood that the fifth SDF template includes the same IP 5-tuple + SSRC1 as the first data stream.

[0209] Similarly, QoS corresponding to a data stream can be understood as a third communication device requesting QoS information to match a specific data stream. In other words, the third communication device can request different QoS for different data streams.

[0210] In some implementations, the fifth SDF template includes at least one of the following:

[0211] Information used to identify the first data stream;

[0212] Information used to identify the second data stream.

[0213] In some implementations, the second SDF template includes information for identifying the second data stream.

[0214] In some implementations, the information used to identify the first data stream includes, but is not limited to, at least one of the following:

[0215] The Media over QUIC Transport (MoQT) field on Quick UDP Internet Connections (QUIC) includes a Track ID, a Synchronization Source (SSRC), a First Field indicating at least one of the Payload Type and Frame Boundaries, a QUIC Connection ID, a QUIC Stream ID, a Media Type, and a Flow ID.

[0216] In some embodiments, the first field may include at least one of a payload type (PT) field and a marker (M) field.

[0217] In some embodiments, the data stream may be a Real-time Transport Protocol (RTP) stream.Figure 3 A structural diagram of an RTP header is shown, such as Figure 3 As shown, the RTP header may include a PT field and an M field, occupying b8-b15 of the RTP header. The PT field is used to indicate the RTP payload type, and the M field is used to indicate whether it is a frame boundary.

[0218] In some embodiments, the data stream may be a Real-Time Control Protocol (RTCP) stream. Figure 4 A structural diagram of an RTCP header is shown, as follows: Figure 4 As shown, the RTCP header may include a PT field, which occupies b8-b15 of the RTCP header, and includes a constant 200 to identify that this is an RTCP Sender Report (SR) packet.

[0219] In some implementations, the information used to identify the second data stream includes, but is not limited to, at least one of the following: IP address; port number; MAC address.

[0220] Figure 5 This is a schematic diagram of another wireless communication method provided in an embodiment of this application. Figure 5 As shown, the method 300 includes at least the following:

[0221] S310, the second communication device performs a third operation, wherein the third operation includes at least one of the following:

[0222] Determine the first policy control and charging (PCC) rules;

[0223] Determine the second PCC rule;

[0224] Send the first PCC rule;

[0225] Send the second PCC rule.

[0226] Optionally, sending the first PCC rule may include sending the first PCC rule to the first communication device.

[0227] Optionally, sending the second PCC rule may include sending the second PCC rule to the second communication device.

[0228] In some embodiments, the second communication device may be a policy-related network element, such as a PCF, or other network elements, which are not limited in this application.

[0229] In some embodiments, the first communication device may be a session-related network element, such as an SMF, or other network elements, which are not limited in this application.

[0230] In some implementations, the first PCC rule satisfies at least one of the following:

[0231] The first PCC rule includes at least one PCC rule;

[0232] The first PCC rule includes at least one of the following:

[0233] First service data stream SDF template, first priority, first QoS.

[0234] Optionally, the first QoS can be a 5G QoS Indicator (5QI).

[0235] In some implementations, the first SDF template includes at least one of the following: information for identifying the first data stream and information for identifying the second data stream. The specific implementations of the first and second data streams are described in the relevant section of method 200, and for the sake of brevity, will not be repeated here.

[0236] In some implementations, the information used to identify the first data stream includes, but is not limited to, at least one of the following:

[0237] The Media over QUIC Transport (MoQT) field on Quick UDP Internet Connections (QUIC) includes a Track ID, a Synchronization Source (SSRC), a First Field indicating at least one of the Payload Type and Frame Boundaries, a QUIC Connection ID, a QUIC Stream ID, a Media Type, and a Flow ID.

[0238] In some implementations, the information used to identify the second data stream includes, but is not limited to, at least one of the following: IP address; port number; MAC address.

[0239] In some implementations, the first SDF template corresponds to the first data stream.

[0240] In some implementations, the first SDF template corresponds to the first QoS.

[0241] In some implementations, the first SDF template includes at least one of the following:

[0242] The third SDF template corresponds to the first data stream;

[0243] The fourth SDF template corresponds to the second data stream.

[0244] In some implementations, the first QoS includes at least one of the following:

[0245] The third QoS corresponds to the first data stream;

[0246] The fourth QoS corresponds to the second data stream.

[0247] In some implementations, the first priority includes:

[0248] The third priority corresponds to the first data stream;

[0249] The fourth priority corresponds to the second data stream.

[0250] In some implementations, the third priority is higher than or equal to the fourth priority.

[0251] It should be noted that the third priority being higher than or equal to the fourth priority can mean that the priority corresponding to the first data stream is higher than or equal to the priority corresponding to the second data stream, indicating that the priority corresponding to the first data stream is higher or equal to the priority corresponding to the second data stream. In this way, the first communication device can formulate QoS rules with different priorities based on different priority sequences; that is, when matching QoS rules, the terminal can prioritize matching the QoS rules corresponding to the first data stream.

[0252] It should be noted that, in the embodiments of this application, a larger priority value indicates a higher priority, or a smaller priority value indicates a higher priority; this application does not impose any limitations.

[0253] In some implementations, the second PCC rule includes at least one of the following: a second SDF template, a second priority, and a second QoS.

[0254] Optionally, the second QoS can be 5QI.

[0255] In some implementations, the second SDF template includes information for identifying the second data stream.

[0256] In some implementations, the second SDF template corresponds to the second data stream.

[0257] In some implementations, the second SDF template corresponds to the second QoS.

[0258] In some implementations, the second priority corresponds to the second data stream.

[0259] In some implementations, the second QoS corresponds to the second data stream.

[0260] It should be noted that, in the embodiments of this application, the data stream corresponding to the SDF template can be understood as: the SDF and the corresponding data stream have the same characteristics. Taking the first data stream as identified by the IP 5-tuple + SSRC1 as an example, if the fifth SDF template corresponds to the first data stream, it can be understood that: the fifth SDF template and the first data stream include the same IP 5-tuple + SSRC1.

[0261] It should be noted that, in this embodiment, "priority corresponding to data stream" can be understood as: the priority information contained in the QoS rules determined by the first communication device based on the PCC rules corresponds to the data stream. It can be understood that the priority in the PCC rules determines the priority of the QoS rules used by the terminal when matching different data streams. Taking the second priority corresponding to the second data stream as an example, the priority of the QoS rules determined based on the PCC rules determines which QoS rule the terminal uses first when matching different QoS rules. The second priority corresponding to the second data stream can be understood as the network side determining the priority information of a QoS rule for matching the second data stream. In other words, the network side can assign different priorities to different data streams.

[0262] Similarly, the QoS-corresponding data stream in this embodiment can be understood as the second communication device determining QoS information for matching the corresponding data stream. In other words, the second communication device can assign different QoS to different data streams.

[0263] In some implementations, the priority of the first PCC rule is higher than or equal to the priority of the second PCC rule. This higher or equal priority of the first PCC rule can be interpreted as the PCC rule corresponding to the second data stream (the second PCC rule) having a lower or equal priority than the PCC rule corresponding to a data stream containing at least one of the first and second data streams (i.e., the first PCC rule). In this way, the first communication device can formulate QoS rules with different priorities based on different priority sequences; that is, when matching QoS rules, the terminal can prioritize matching the QoS rule corresponding to the first data stream.

[0264] In some embodiments of this application, the second communication device performs a third operation, including:

[0265] The second communication device performs the third operation based on at least one of the following:

[0266] The first request message from the third communication device, local configuration information, and Service Level Agreement (SLA).

[0267] Optionally, the third communication device can be an application-related device, such as an application server, AF, etc.

[0268] Optionally, the first request information is used to request QoS and / or reserve resources for the AF session.

[0269] In some implementations, the first request message includes at least one of the following:

[0270] Fifth SDF template;

[0271] Sixth SDF template;

[0272] Fifth QoS;

[0273] The sixth QoS.

[0274] In some implementations, the fifth SDF template corresponds to the first data stream. In this case, the QoS rules determined by the first communication device based on the fifth SDF template can be used to identify the first data stream.

[0275] In some implementations, the fifth SDF template corresponds to the fifth QoS.

[0276] In some implementations, the sixth SDF template corresponds to the second data stream. In this case, the QoS rules determined by the first communication device based on the sixth SDF template can be used to identify the second data stream.

[0277] In some implementations, the sixth SDF template corresponds to the sixth QoS.

[0278] In some implementations, the fifth QoS corresponds to the fifth SDF template.

[0279] In some implementations, the fifth QoS corresponds to the first data stream. In this case, the first communication device can satisfy the QoS of the first data stream based on the QoS rules determined by the fifth QoS.

[0280] In some implementations, the sixth QoS corresponds to the second SDF template.

[0281] In some implementations, the sixth QoS corresponds to the second data stream. In this case, the first communication device can satisfy the QoS of the second data stream based on the QoS rules determined by the sixth QoS.

[0282] In some implementations, the fifth SDF template includes at least one of the following:

[0283] The seventh SDF template corresponds to the first data stream;

[0284] The eighth SDF template corresponds to the second data stream.

[0285] In this case, the QoS rules determined by the first communication device based on the fifth SDF template can be used to identify the first data stream and / or the second data stream.

[0286] In some implementations, the fifth QoS includes at least one of the following:

[0287] The seventh QoS corresponds to the first data stream;

[0288] The eighth QoS corresponds to the second data stream.

[0289] Then the first communication device can satisfy the QoS of the first data stream and / or the second data stream according to the QoS rules determined by the fifth QoS.

[0290] In some implementations, the fifth SDF template includes at least one of the following:

[0291] Information used to identify the first data stream;

[0292] Information used to identify the second data stream.

[0293] In this case, the QoS rules determined by the first communication device based on the fifth SDF template can be used to identify the first data stream and / or the second data stream.

[0294] In some implementations, the sixth SDF template includes information for identifying the second data stream. In this case, the QoS rules determined by the first communication device based on the sixth SDF template can be used to identify the second data stream.

[0295] In some implementations, the information used to identify the first data stream includes at least one of the following:

[0296] Media transmission on QUIC via Fast User Datagram Protocol (UDP) network connection: MoQT track identifier, synchronization source SSRC, first field indicating at least one of payload type and frame boundary, QUIC connection identifier, QUIC stream identifier, media type, and data stream identifier.

[0297] In some implementations, the information used to identify the second data stream includes at least one of the following: IP address; port number; MAC address.

[0298] Figure 6 This is a schematic diagram of another wireless communication method provided in an embodiment of this application. Figure 6As shown, the method 400 includes at least the following:

[0299] S410, the first communication device performs at least one of the first operation and the second operation;

[0300] The first operation includes at least one of the following:

[0301] Determine the first Quality of Service (QoS) rule;

[0302] Determine the second QoS rule;

[0303] Send the first QoS rule;

[0304] Send the second QoS rule;

[0305] The second operation includes at least one of the following:

[0306] Delete the third QoS rule;

[0307] Send the fourth QoS rule to the terminal;

[0308] Determine whether to maintain or not delete the QoS file;

[0309] Determine whether to maintain or not delete the QoS flow;

[0310] The first QoS rule includes at least a first filter;

[0311] The second QoS rule includes a second filter;

[0312] The third QoS rule includes at least the first filter;

[0313] The fourth QoS rule includes at least one of the first filter and the second filter;

[0314] The QoS file corresponds to the third QoS rule;

[0315] The QoS flow corresponds to the third QoS rule.

[0316] In some embodiments, the first communication device may be a session-related network element, such as an SMF, or other network elements, which are not limited in this application.

[0317] In some implementations, optionally, after the first communication device determines whether to maintain or not delete the QoS file, the method further includes: the first communication device performing the maintenance or non-deletion of the QoS file.

[0318] In some implementations, optionally, after the first communication device determines whether to maintain or not delete the QoS flow, the method further includes: the first communication device performing the maintenance or non-deletion of the QoS flow.

[0319] Optionally, sending the first QoS rule may include: sending the first QoS rule to the terminal.

[0320] Optionally, sending the second QoS rule may include: sending the second QoS rule to the terminal.

[0321] It should be noted that, in the embodiments of this application, the filter, also known as a package filter, filter component, or package filter assembly, may include filter type and filter content.

[0322] The first filter and the second filter will be described below.

[0323] In some embodiments, the first filter satisfies at least one of the following:

[0324] The first filter is used to filter data packets;

[0325] The first filter is used in conjunction with the second filter to filter data packets;

[0326] The first filter does not support being used alone to filter data packets;

[0327] The first filter includes at least one of the following:

[0328] Information used to identify the first data stream;

[0329] Information used to identify the second data stream.

[0330] The specific implementations of the first data stream and the second data stream are described in the relevant description in method 200, and will not be repeated here for the sake of brevity.

[0331] In some embodiments, the first filter is used to filter data packets and may include at least one of the following:

[0332] The first filter is used to filter data packets in the data stream;

[0333] The first filter is used to filter packets in the QoS stream.

[0334] In some implementations, the first filter used to filter data packets may include: the first filter can be used alone to filter data packets; for example, the first filter can be used alone to filter data packets in a data stream or data packets in a QoS stream. That is, the first filter can be used alone to form a filter for QoS rules, denoted as mode 1.

[0335] In some implementations, the first filter used to filter data packets may include: the first filter not being supported for filtering data packets alone; for example, the first filter and the second filter being combined to filter data packets, such as filtering data packets in a data stream or data packets in a QoS stream. That is, the first filter cannot be used alone to form a filter for a QoS rule; it needs to be combined with the second filter to form a filter for a QoS rule, denoted as mode 2.

[0336] In some embodiments, the second filter satisfies at least one of the following:

[0337] The second filter includes at least one of the following: match all, IPv4 remote address, IPv4 local address, IPv6 remote address / prefix length, IPv6 local address / prefix length, protocol identifier / next header, single local port, local port range, single remote port, remote port range, security parameter index, service type / flow class, flow label, destination MAC address, source MAC address, 802.1Q C-TAG VID, 802.1Q S-TAG VID, 802.1Q C-TAG PCP / DEI, 802.1Q S-TAG PCP / DEI, Ethernet type, destination MAC address range, source MAC address range;

[0338] The second filter is used to filter data packets;

[0339] The second filter does not include the first filter;

[0340] The second filter can be used alone to filter data packets.

[0341] In some implementations, the first filter and the second filter are used together to filter packets in a QoS flow.

[0342] In some implementations, the second filter can be used alone to form the filters of the QoS rules.

[0343] In some implementations, the second filter is used to filter packets of the QoS stream, or packets of the data stream.

[0344] In some implementations, the second data stream includes multiple multiplexed sub-data streams (e.g., when multiple media streams are multiplexed in the same IP 5-tuple, the second data stream includes multiple sub-data streams (such as video streams, audio streams, etc.). The terminal needs to identify the different media streams (such as video streams, audio streams, etc.)). The terminal can determine the second data stream using a second filter. The terminal can also determine the sub-data streams in the second data stream by using a combination of the second filter and the first filter.

[0345] In some implementations, the second data stream is a multiplexed data stream of multiple sub-data streams, where sub-data stream 1 is IP#1+port#1+SSRC#1; and sub-data stream 2 is IP#1+Port#1+SSRC#2. The first filter includes IP#1+port#1+SSRC#1 and IP#1+port#1+SSRC#2; the second filter includes IP#1+port#1. Thus, the terminal can perform data stream detection or QoS stream mapping based on the first filter to identify sub-data stream 1 and sub-data stream 2. Alternatively, the terminal can perform data stream detection or QoS stream mapping based on the second filter. While the terminal cannot identify sub-data stream 1 or sub-data stream 2, it can identify the second data stream, ensuring that the terminal has at least one suitable filter (i.e., the second filter) available.

[0346] In some implementations, the first QoS rule is used for at least one of the following:

[0347] Classify or tag UL user data; associate UL traffic with QoS flows.

[0348] In some implementations, the first QoS rule includes one or more QoS rules, wherein each QoS rule includes one or more filters, such as at least a first filter. Optionally, a second filter may also be included.

[0349] For example, the second filter can be used to filter data packets alone, and the first filter and the second filter can be combined to filter data packets. The first QoS rule can include the first filter and the second filter. Then the terminal can identify the second data stream through the second filter, and determine the sub-data stream in the second data stream, i.e. the first data stream, by using the combination of the second filter and the first filter.

[0350] In some embodiments, the priority of the first QoS rule is higher than or equal to the priority of the second QoS rule. This higher priority of the first QoS rule can be interpreted as the QoS rule corresponding to the second data stream having a lower priority than or equal to the QoS rule corresponding to a data stream containing at least one of the first and second data streams. Thus, when matching QoS rules, the terminal can prioritize matching the QoS rule corresponding to the first data stream.

[0351] In some embodiments, the first QoS rule further includes the second filter. For example, when the first filter and the second filter are combined to filter data packets, the first QoS rule further includes the second filter.

[0352] In some embodiments, the first filter and the second filter are filters from the same filter list, corresponding to mode 1.

[0353] In other embodiments, the first filter and the second filter are filters from different filter lists (corresponding to mode 2), and the second filter does not include the first filter.

[0354] In some implementations, the second filter does not include the first filter, which can be understood as: the filter components included in the second filter do not include the filter components included in the first filter.

[0355] Therefore, in this embodiment, the first communication device can issue a first QoS rule including a first filter and a second filter. This way, even if the terminal does not support the first filter, the terminal can still match QoS flows based on the QoS rule including the second filter to meet the requirements of XR services. Alternatively, the first communication device can issue a first QoS rule including both the first and second filters, and a second QoS rule including the second filter. This way, even if the terminal does not support the first QoS rule including the first filter, the terminal can still use the second QoS rule including the second filter to match QoS flows and meet the requirements of XR services.

[0356] This application provides two designs for QoS rule information elements (IEs) used to carry filters.

[0357] Figure 7 This is a structural diagram of a QoS rule IE provided in an embodiment of this application. For example... Figure 7 As shown in (a), a QoS rule IE includes at least one QoS rule field, such as Figure 7 As shown in (b), each QoS rule field may include a packet filter list field, which may include at least one packet filter component, wherein the packet filter component may be a first filter or a second filter. That is, both the first filter and the second filter can belong to the filter list. This structure design is applicable to scenarios where the first filter can be used alone to filter data packets.

[0358] Figure 8 This is a structural diagram of another QoS rule IE provided in an embodiment of this application. For example... Figure 8 As shown in (a), a QoS rule IE can include at least one QoS rule field, such as Figure 8As shown in (b), each QoS rule field may include a first packet filter list field and a second packet filter list field (optional). The first packet filter list field may include at least one second packet filter, and the second packet filter list field may include at least one first filter. That is, the first filter and the second filter may belong to different filter lists. This structure design is suitable for scenarios where the first filter cannot be used alone to filter packets.

[0359] It should be noted that, Figure 7 and Figure 8 The naming, length, and position of each field in this application are merely examples and can be flexibly adjusted according to actual needs. This application does not impose any restrictions on them.

[0360] In some embodiments of this application, the method 400 further includes:

[0361] The first communication device acquires second information, which includes at least one of local configuration information and first information.

[0362] In some embodiments, the first communication device performs a first operation, including:

[0363] The first communication device performs the first operation based on the second information.

[0364] In some implementations, the first information is used to indicate at least one of the following:

[0365] The terminal may or may not support the first filter;

[0366] The terminal may or may not support QoS rules that include the first filter.

[0367] Optionally, the first information may be sent by the terminal to the first communication device, or it may be sent by other network functions, such as AMF, PCF, UDM, etc., to the first communication device. This is not limited in the embodiments of this application.

[0368] Optionally, the terminal sends the first information via a PDU session establishment request message or a PDU session modification request message.

[0369] Optionally, the first information may be included in session management capabilities. For example, the first information may be included in 5GSM capabilities.

[0370] Optionally, the first information may also be derived from the first communication device, for example, based on local configuration information or parameter information related to the terminal.

[0371] Optionally, local configuration information may include, but is not limited to, local default configuration and terminal subscription information. Optionally, the local default configuration may be that the terminal supports the first filter by default, or that the terminal supports QoS rules including the first filter by default, or that the terminal does not support the first filter by default, or that the terminal does not support QoS rules including the first filter by default.

[0372] In some implementations, terminal support for the first filter can be understood as: the terminal supports data flow detection or QoS flow mapping based on the first filter. Optionally, terminal performance of data flow detection or QoS flow mapping based on the first filter can be understood as: the terminal performs data flow detection or QoS flow mapping based on both the first and second filters, i.e., the terminal uses both the first and second filters in combination for data flow detection or QoS flow mapping.

[0373] In some embodiments, the first communication device performs a first operation, including:

[0374] If a first condition is met, the first communication device performs at least one of determining the first QoS rule and sending the first QoS rule, wherein the first condition includes at least one of the following:

[0375] The terminal supports the first filter and the network-side device supports the first filter;

[0376] The terminal supports QoS rules that include the first filter, and the network-side device also supports QoS rules that include the first filter.

[0377] Optionally, whether the terminal supports the first filter may be determined by the first communication device based on the first information, or it may be determined based on local configuration information, or it may be derived based on other information. This application does not limit this.

[0378] In some implementations, if the first condition is met, the first QoS rule satisfies at least one of the following:

[0379] The first QoS rule does not include the second filter;

[0380] The first QoS rule includes the first filter.

[0381] Therefore, if the first condition is met, the terminal supports the first filter or supports QoS rules including the first filter. Thus, the first communication device can send the first QoS rules including the first filter to the terminal. In this way, the terminal can match QoS flows based on the first QoS rules including the first filter to meet the requirements of XR services.

[0382] In some implementations, the first communication device performs a first operation, including:

[0383] If the second condition is met, the first communication device performs at least one of determining the second QoS rule and transmitting the second QoS rule, wherein the second condition includes at least one of the following:

[0384] The terminal does not support the first filter;

[0385] The network-side device does not support the first filter;

[0386] The terminal does not support QoS rules that include the first filter;

[0387] The network-side device does not support QoS rules that include the first filter.

[0388] In some implementations, when the second condition is met, the first communication device can send a first QoS rule including a first filter and a second filter to the terminal. Thus, even if the terminal does not support the first filter, it can still match the QoS flow based on the first QoS rule including the second filter, ensuring the normal transmission of the XR service. Alternatively, the first communication device can send a first QoS rule including the first filter and a second QoS rule including the second filter. Thus, even if the terminal does not support the first QoS rule including the first filter, it can still use the second QoS rule including the second filter to match the QoS flow, ensuring the normal transmission of the XR service.

[0389] In some implementations, when the second condition includes the terminal not supporting the first filter or the terminal not supporting QoS rules including the first filter, the filtering direction of the first filter is set to downlink only (DL only).

[0390] It should be noted that when the filtering direction of the first filter is set to downlink only, the first filter is only applicable to downlink, therefore the terminal cannot use the first filter to match UL packets. However, the QoS flow corresponding to the first filter can still be used in the DL direction, which helps improve resource utilization.

[0391] In some embodiments of this application, before the first communication device performs the first operation, the method 400 further includes:

[0392] The first communication device acquires at least one of the first PCC rule and the second PCC rule;

[0393] The first communication device performs a first operation, including:

[0394] The first communication device performs the first operation based on at least one of the first PCC rule and the second PCC rule. For example, a first QoS rule is determined based on the first PCC rule, and a second QoS rule is determined based on the second PCC rule.

[0395] In some implementations, the first PCC rule satisfies at least one of the following:

[0396] The first PCC rule includes at least one PCC rule;

[0397] The first PCC rule includes at least one of the following:

[0398] First Service Data Flow Template (SDF), First Priority, First QoS.

[0399] Optionally, the first QoS can be a 5G QoS Indicator (5QI).

[0400] In some implementations, the first SDF template satisfies at least one of the following:

[0401] The first SDF template includes at least one of the following: information for identifying a first data stream and information for identifying a second data stream, that is, the first QoS rule determined based on the first SDF template can be used to identify the first data stream and / or the second data stream;

[0402] The first SDF template corresponds to the first data stream;

[0403] The first SDF template corresponds to the first QoS.

[0404] In some implementations, the first SDF template includes at least one of the following:

[0405] The third SDF template corresponds to the first data stream;

[0406] The fourth SDF template corresponds to the second data stream.

[0407] In some implementations, the first QoS includes at least one of the following:

[0408] The third QoS corresponds to the first data stream;

[0409] The fourth QoS corresponds to the second data stream.

[0410] In some implementations, the first priority includes:

[0411] The third priority corresponds to the first data stream;

[0412] The fourth priority corresponds to the second data stream.

[0413] In some implementations, the third priority is higher than or equal to the fourth priority.

[0414] The third priority being higher than or equal to the fourth priority can mean that the priority corresponding to the first data stream is higher than or equal to the priority corresponding to the second data stream, indicating that the priority corresponding to the first data stream is higher or equal to the priority corresponding to the second data stream. In this way, the first communication device can formulate QoS rules with different priorities based on different priority sequences; that is, when matching QoS rules, the terminal can prioritize matching the QoS rule corresponding to the first data stream.

[0415] It should be noted that, in the embodiments of this application, a larger priority value indicates a higher priority, or a smaller priority value indicates a higher priority; this application does not impose any limitations.

[0416] In some implementations, the second PCC rule includes at least one of the following: a second SDF template, a second priority, and a second QoS.

[0417] Optionally, the second QoS can be 5QI.

[0418] In some implementations, the second SDF template includes information for identifying the second data stream.

[0419] In some implementations, the second SDF template corresponds to the second data stream.

[0420] In some implementations, the second SDF template corresponds to the second QoS.

[0421] In some implementations, the second priority corresponds to the second data stream.

[0422] In some implementations, the second QoS corresponds to the second data stream.

[0423] It should be noted that, in the embodiments of this application, the SDF corresponding to the data stream can be understood as: the SDF and the corresponding data stream have the same characteristics. Taking the first data stream identified by the IP 5-tuple + SSRC1 as an example, if the first SDF corresponds to the first data stream, it can be understood that: the first SDF template and the first data stream include the same IP 5-tuple + SSRC1.

[0424] It should be noted that, in this embodiment, "priority corresponding to data stream" can be understood as: the priority information contained in the QoS rules determined by the first communication device based on the PCC rules corresponds to the data stream. It can be understood that the priority in the PCC rules determines the priority of the QoS rules used by the terminal when matching different data streams. Taking the second priority corresponding to the second data stream as an example, the priority of the QoS rules determined based on the PCC rules determines which QoS rule the terminal uses first when matching different QoS rules. The second priority corresponding to the second data stream can be understood as the network side determining the priority information of a QoS rule for matching the second data stream. In other words, the network side can assign different priorities to different data streams.

[0425] Similarly, the QoS corresponding to a data stream can be understood as the network side determining a QoS rule and / or QoS profile for matching the corresponding data stream. In other words, the network side can assign different QoS to different data streams.

[0426] In some implementations, the priority of the first PCC rule is higher than or equal to the priority of the second PCC rule. This higher or equal priority of the first PCC rule can be interpreted as the PCC rule corresponding to the second data stream (the second PCC rule) having a lower or equal priority to the PCC rule corresponding to a data stream containing at least one of the first and second data streams (i.e., the first PCC rule). Thus, the first communication device can formulate QoS rules with different priorities based on these priorities; that is, when matching QoS rules, the terminal can prioritize matching the QoS rule corresponding to the first data stream.

[0427] In some embodiments of this application, the method 200 further includes:

[0428] The first communication device receives third information from the terminal, the third information being used to indicate a request to delete a third QoS rule.

[0429] In some embodiments, the third information includes a first cause value, which indicates at least one of the following: a filter syntax error; or a QoS rule syntax error.

[0430] Optionally, a filter syntax error can indicate that the filter cannot be recognized, and a QoS rule syntax error can indicate that the QoS rule cannot be recognized.

[0431] In some embodiments, the third QoS rule includes the first filter.

[0432] In some embodiments, the third QoS rule includes the first filter, wherein the filtering direction of the first filter is either uplink only (UL only) or bidirectional.

[0433] Optionally, the first filter in the third QoS rule includes information for identifying the first data stream. This may include, for example, at least one of the following: MoQT track identifier, SSRC, a first field indicating at least one of payload type and frame boundary, QUIC connection identifier, QUIC stream identifier, media type, and stream identifier.

[0434] In some embodiments, the fourth QoS rule includes a second filter.

[0435] Therefore, in some embodiments of this application, when the first communication device receives the third information from the terminal, the first communication device can know that the terminal does not support the first filter. Alternatively, when the first communication device receives the third information from the terminal, the first communication device determines that the QoS rule requested by the terminal to be deleted includes the first filter, and thus knows that the first communication device does not support the first filter. Therefore, the first communication device can send the QoS rule including the second filter to the UE, so that the terminal has a suitable QoS rule to match UL data packets, ensuring the normal transmission of XR services.

[0436] In some embodiments, the first communication device performs a second operation, including:

[0437] The first communication device performs the second operation based on the third information.

[0438] In some embodiments, the fourth QoS rule includes the first filter; wherein the filtering direction of the first filter is downlink only.

[0439] Therefore, in some embodiments of this application, when the first communication device receives the third information from the terminal, the first communication device can know that the terminal does not support the first filter. Alternatively, when the first communication device receives the third information from the terminal, the first communication device determines that the QoS rule requested by the terminal to be deleted includes the first filter, and thus knows that the first communication device does not support the first filter. Therefore, the first communication device can send the QoS rule including the first filter to the terminal and set the filtering direction of the first filter to downlink only, so that the downlink data of the terminal can use the first filter, thereby improving resource utilization.

[0440] In some embodiments, the QoS profile corresponds to the third QoS rule, including: the QoS flow identifier (QFI) corresponding to the QoS profile is the same as the QFI in the third QoS rule.

[0441] Optionally, in the embodiments of this application, each QoS profile corresponds to one QFI, that is, the QoS profile and QFI are associated.

[0442] In some embodiments, the QoS flow corresponds to the third QoS rule, including: the QFI of the QoS flow is the same as the QFI in the third QoS rule. Optionally, in the embodiments of this application, each QoS flow corresponds to one QFI, that is, the QoS flow and the QFI are associated.

[0443] Therefore, in this embodiment of the application, when the terminal requests a QoS rule including the first filter, the first communication device can set the filtering direction of the first filter to downlink only and retain the communication resources corresponding to the QoS rule, such as QoS files and QoS streams, so that the first filter can match the downlink data of the terminal for the downlink data transmission of the terminal, thereby improving resource utilization.

[0444] Figure 9 This is a schematic diagram illustrating a wireless communication method provided in an embodiment of this application. Figure 9 As shown, the method 500 includes at least the following:

[0445] S510, the terminal performs a fourth operation, the fourth operation including at least one of the following:

[0447] Send the first message to the first communication device;

[0448] Send third information to the first communication device;

[0449] Receive the fourth QoS rule from the first communication device;

[0450] Wherein, the first information is used to indicate at least one of the following: the terminal supports or does not support the first filter, or the terminal supports or does not support QoS rules including the first filter;

[0451] The third information is used to indicate a request to delete the third QoS rule;

[0452] The first QoS rule includes at least a first filter;

[0453] The second QoS rule includes a second filter;

[0454] The third QoS rule includes at least the first filter;

[0455] The fourth QoS rule includes at least one of the first filter and the second filter.

[0456] In some embodiments, the first communication device may be a session-related network element, such as an SMF, or other network elements, which are not limited in this application.

[0457] In some embodiments, the priority of the first QoS rule is higher than or equal to the priority of the second QoS rule.

[0458] In some embodiments, the first QoS rule further includes the second filter.

[0459] In some embodiments, the first filter and the second filter are filters from the same filter list; or

[0460] The first filter and the second filter are filters from different filter lists, and the second filter does not include the first filter.

[0461] In some embodiments, the first filter satisfies at least one of the following:

[0462] The first filter is used to filter data packets;

[0463] The first filter is used in conjunction with the second filter to filter data packets;

[0464] The first filter does not support being used alone to filter data packets;

[0465] The first filter includes at least one of the following:

[0466] Information used to identify the first data stream;

[0467] Information used to identify the second data stream.

[0468] In some embodiments, the information for identifying the first data stream includes at least one of the following:

[0469] Media transmission on QUIC via Fast User Datagram Protocol (UDP) network connection: MoQT track identifier, synchronization source SSRC, first field indicating at least one of payload type and frame boundary, QUIC connection identifier, QUIC stream identifier, media type, and data stream identifier.

[0470] In some embodiments, the information used to identify the second data stream includes at least one of the following: IP address; port number; MAC address.

[0471] In some embodiments, the second filter satisfies at least one of the following:

[0472] The second filter includes at least one of the following: match all, IPv4 remote address, IPv4 local address, IPv6 remote address / prefix length, IPv6 local address / prefix length, protocol identifier / next header, single local port, local port range, single remote port, remote port range, security parameter index, service type / flow class, flow label, destination MAC address, source MAC address, 802.1Q C-TAG VID, 802.1Q S-TAG VID, 802.1Q C-TAG PCP / DEI, 802.1Q S-TAG PCP / DEI, Ethernet type, destination MAC address range, source MAC address range;

[0473] The second filter is used to filter data packets;

[0474] The second filter does not include the first filter;

[0475] The second filter can be used alone to filter data packets.

[0476] Therefore, in this embodiment, the first communication device can issue a first QoS rule including a first filter and a second filter. This way, even if the terminal does not support the first filter, the terminal can still match QoS flows based on the QoS rule including the second filter to meet the requirements of XR services. Alternatively, the first communication device can issue a first QoS rule including both the first and second filters, and a second QoS rule including the second filter. This way, even if the terminal does not support the first QoS rule including the first filter, the terminal can still use the second QoS rule including the second filter to match QoS flows and meet the requirements of XR services.

[0477] In some embodiments, the third QoS rule includes the first filter, wherein the filtering direction of the first filter is either uplink only or bidirectional.

[0478] In some embodiments, the fourth QoS rule includes the first filter; wherein the filtering direction of the first filter is downlink only.

[0479] Therefore, in this embodiment of the application, when the terminal requests a QoS rule including the first filter, the first communication device can set the filtering direction of the first filter to downlink only and retain the communication resources corresponding to the QoS rule, such as QoS files and QoS streams, so that the first filter can match the downlink data of the terminal for the downlink data transmission of the terminal, thereby improving resource utilization.

[0480] Optionally, in some embodiments, the method 500 further includes:

[0484] Optionally, the fourth information may be sent before the terminal sends the first information. Optionally, the terminal may send the first information if the network-side device supports the first filter, and / or if the network-side device supports QoS rules including the first filter. The first information is used to indicate that the terminal supports the first filter, or that the terminal supports QoS rules including the first filter.

[0485] Optionally, the fourth information may be included in the registration acceptance message. For example, the fourth information may be included in the 5GS network feature support IE of the registration acceptance message sent by the AMF.

[0519] In some embodiments, the second filter is used to filter data packets.

[0520] In some embodiments, the second filter does not include the first filter.

[0521] In some embodiments, the second filter can be used alone to filter data packets.

[0522] The specific implementations of the first QoS rule, the second QoS rule, the first filter, and the second filter are described in the foregoing embodiments. For the sake of brevity, the steps are not repeated here.

[0523] Step 605, SMF performs the first operation.

[0524] Optionally, the first QoS rule can be established by accepting message sending through a PDU session.

[0525] Optionally, the second QoS rule can be established by accepting message sending through a PDU session.

[0526] like Figure 11 As shown, the wireless communication method may include the following steps:

[0527] Step 702: The terminal sends the first information to the SMF.

[0528] The first piece of information is used to indicate at least one of the following:

[0529] The terminal may or may not support the first filter;

[0530] The terminal may or may not support QoS rules including the first filter.

[0531] Optionally, the terminal can establish a message carrying the first information through a PDU session.

[0534] The network-side device may or may not support the first filter;

[0535] The network-side device may or may not support QoS rules that include the first filter.

[0536] Optionally, the terminal may send first information if the network-side device supports the first filter and / or if the network-side device supports QoS rules including the first filter. The first information is used to indicate that the terminal supports the first filter or that the terminal supports QoS rules including the first filter.

[0537] Optionally, the fourth information may be included in the registration acceptance message. For example, the fourth information may be included in the 5GS network feature support IE of the registration acceptance message sent by the AMF. Step 703, the SMF performs the first operation.

[0538] The first operation includes at least one of the following:

[0539] Determine the first QoS rule;

[0540] Determine the second QoS rule;

[0541] Send the first QoS rule;

[0542] Send the second QoS rule.

[0543] This step 703 can correspond to the aforementioned step 604.

[0544] Optionally, the method may further include: the SMF acquiring second information, the second information including at least one of local configuration information and first information.

[0545] For example, before step 703, the SMF obtains second information and further performs the first operation based on the second information. For specific implementation details, please refer to the relevant descriptions in the foregoing embodiments; for brevity, they will not be repeated here.

[0546] like Figure 12 As shown, the wireless communication method may include the following steps:

[0547] Step 802: The terminal sends third information to the SMF to request the deletion of the third QoS rule.

[0548] Optionally, the third information can be sent via a PDU session modification request message.

[0549] In some embodiments, the third information includes a first cause value, which indicates at least one of the following: a filter syntax error; or a QoS rule syntax error.

[0550] In some embodiments, the third QoS rule includes the first filter.

[0551] In some embodiments, the third QoS rule includes the first filter, wherein the filtering direction of the first filter is either uplink only (UL only) or bidirectional.

[0552] Step 803, SMF performs the second operation.

[0553] Delete the third QoS rule;

[0554] Send the fourth QoS rule to the terminal.

[0555] Optionally, a fourth QoS rule may be sent to the terminal, including modifying the fourth QoS rule for receiving messages via the PDU session.

[0556] In some embodiments, the fourth QoS rule includes a second filter.

[0557] Therefore, in some embodiments of this application, when the first communication device receives the third information from the terminal, the first communication device can know that the terminal does not support the first filter. Alternatively, when the first communication device receives the third information from the terminal, the first communication device determines that the QoS rule requested to be deleted by the terminal includes the first filter, and thus knows that the first communication device does not support the first filter. Therefore, the first communication device can send the QoS rule including the second filter to the UE, so that the terminal has a suitable QoS rule to match UL data packets.

[0558] In some embodiments, the fourth QoS rule includes the first filter; wherein the filtering direction of the first filter is downlink only.

[0559] Therefore, in some embodiments of this application, when the first communication device receives the third information from the terminal, the first communication device can know that the terminal does not support the first filter. Alternatively, when the first communication device receives the third information from the terminal, the first communication device determines that the QoS rule requested by the terminal to be deleted includes the first filter, and thus knows that the first communication device does not support the first filter. Therefore, the first communication device can send the QoS rule including the first filter to the terminal and set the filtering direction of the first filter to downlink only, so that the downlink data of the terminal can use the first filter.

[0560] like Figure 13 As shown, the wireless communication method may include the following steps:

[0561] Step 902: The terminal sends third information to the SMF to request the deletion of the third QoS rule.

[0562] Optionally, the third information can be sent via a PDU session modification request message.

[0563] In some embodiments, the third information includes a first cause value, which indicates at least one of the following: a filter syntax error; or a QoS rule syntax error.

[0564] In some embodiments, the third QoS rule includes the first filter.

[0565] In some embodiments, the third QoS rule includes the first filter, wherein the filtering direction of the first filter is either uplink only (UL only) or bidirectional.

[0566] Step 903, SMF performs the second operation.

[0567] Determine whether to maintain or not delete the QoS file;

[0568] Decide whether to maintain or not delete the QoS flow.

[0569] In some embodiments, the filtering direction of the first filter is set to downlink only.

[0570] In some implementations, optionally, after the SMF determines whether to maintain or not delete the QoS file, the method further includes: the SMF performing the maintenance or non-deletion of the QoS file.

[0571] In some implementations, optionally, after the SMF determines whether to maintain or not delete the QoS flow, the method further includes: the SMF performing the maintenance or non-deletion of the QoS flow.

[0572] Therefore, in this embodiment of the application, when the terminal requests a QoS rule including the first filter, the first communication device can set the filtering direction of the first filter to downlink only and retain the communication resources corresponding to the QoS rule, such as QoS files and QoS streams, so that the first filter can match the downlink data of the terminal for the downlink data transmission of the terminal, thereby improving resource utilization.
