[0144] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0145] The terms "first", "second", etc. in this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects, for example, the first object can be one or more. In addition, "or" in this application represents at least one of the connected objects. For example, "A or B" covers three options, namely, Option 1: including A but not including B; Option 2: including B but not including A; Option 3: including both A and B. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0146] The term "indication" in this application can be either a direct indication (or explicit indication) or an indirect indication (or implicit indication). A direct indication can be understood as the sender explicitly informing the receiver of specific information, the operation to be performed, or the requested result, etc. in the instruction sent; an indirect indication can be understood as the receiver determining the corresponding information based on the instruction sent by the sender, or making a judgment and determining the operation to be performed or the requested result, etc. based on the judgment result.

[0147] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA) or other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the technology described can be used for the systems and radio technologies mentioned above, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for illustrative purposes, and NR terminology is used in most of the following description, but these technologies can also be applied to systems other than NR systems, such as 6th generation (6G) systems. thGeneration, 6G) communication system.

[0148] Packet set delay, also known as the Packet Set Delay Budget (PSDB), (optionally, the Packet Set Delay Budget includes the Packet Data Unit Set Delay Budget (PDU Set Delay Budget, PSDB)). Unlike the Packet Delay Budget (PDB), which is the delay budget for a single packet, the PSDB is the delay budget for a group of packets (for example, the time from receiving the first packet in packet set t to the complete transmission of all packets should not exceed the PSDB). For details, see Figure 1a.

[0149] As shown in Figure 1b, in some scenarios, the first device 10 accesses the network through the terminal 11, so the service device can also be called the device behind the terminal (Tethered Device). When the first device interacts with the application server through the terminal and the network for service data, the delay budget for the data packet set provided by the application function (AF) to the network is nominally the delay budget between the terminal and the anchor gateway, but in reality it is the delay budget between the first device and the anchor gateway. The first device is the device where the service terminates, not the terminal device (such as the user equipment (UE)). The service, such as the device for the Extended Reality (XR) service, can be referred to as the first device) and the delay between the user plane function (UPF).

[0150] As shown in Figure 1c, the PSDB provided by the AF is 20ms, and the latency between the first device and the terminal is 3ms. If the 5GS guarantees the latency based on 20ms, for example, it takes 19ms to transmit all data packets of the PDU Set to the terminal, and 22ms to reach the first device. The data packet is 2ms late, which will cause the service QoE to be unguaranteed, such as lag, jitter, and screen distortion.

[0151] The Radio Access Network (RAN) is responsible for guaranteeing the air interface latency between the RAN and the terminal, known as the AN PSDB. Similarly, in the scenario involving the first device, if the latency between the terminal and the first device, or the latency budget, is not considered, the guaranteed AN PSDB will be incorrect. See Figure 1d for details.
