Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0059] Figure 1 This is a schematic diagram of a wireless communication system 100 applicable to embodiments of this application.

[0060] like Figure 1 As shown, the wireless communication system 100 may include at least one access network device, such as Figure 1 The network device 110 is shown. The wireless communication system 100 may also include at least one terminal device, such as... Figure 1 The terminal device 120 shown.

[0062] It should be understood that this application does not limit the specific form of the terminal device.

[0063] The network device in this application embodiment can be a device with wireless transceiver function in the access network, such as... Figure 1 The access network device 110 shown includes, but is not limited to: base stations, evolved node B (eNB), next-generation node B (gNB) radio network controllers (RNC), node B (NB), access points (APs), wireless relay nodes, wireless backhaul nodes, transmission points (TPs), or transmission and reception points (TRPs) in a wireless fidelity (WIFI) system. This device can also be a network node constituting a gNB or transmission point, such as a baseband unit (BBU), a centralized unit (CU), or a distributed unit (DU).

[0064] In this application embodiment, the device for implementing the functions of the terminal device can be the terminal device itself, or it can be a device capable of supporting the terminal device in implementing the functions, such as a chip system. This device can be installed in the terminal device or used in conjunction with the terminal device. In this application embodiment, the chip system can be composed of chips, or it can include chips and other discrete devices. In this application embodiment, taking the terminal device as an example to illustrate the provided technical solution, we will describe it accordingly.

[0065] The technical solution of this application and how the technical solution of this application solves the technical problem are described in detail below with specific embodiments. The embodiments described below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0066] Figure 2 This is a schematic flowchart of the slice selection method provided in this application. Figure 2 The slice selection method shown can be executed by a communication device, which can be a communication equipment or a communication device configured within a communication equipment, such as a chip configured in a terminal device. The following description uses a terminal device executing this slice selection method as an example; however, it should be understood that this application is not limited to this. This slice selection method includes, but is not limited to, the following steps:

[0067] S201, the first business requirement for terminal devices to obtain services.

[0068] The first business requirement includes one or more of the following: real-time rate requirement, maximum uplink rate requirement, maximum downlink rate requirement, reliability requirement, latency requirement, or security isolation requirement. Security isolation requirement refers to whether business data requires encryption protection and / or integrity protection.

[0069] In one implementation, the terminal device can obtain the first service requirement of the service from the application layer of the terminal device.

[0070] In another implementation, the terminal device receives second configuration information from the network device and obtains the first service requirement based on the second configuration information.

[0071] For example, the terminal device can obtain the real-time rate requirements and / or security isolation requirements of the service from the application layer. As another example, the second configuration information can indicate maximum uplink rate requirements, maximum downlink rate requirements, reliability requirements, latency requirements, etc. However, this application is not limited to these.

[0072] S202, the terminal device determines the first slice based on the first service requirement.

[0073] In one embodiment, the terminal device determines first service description information based on first service requirements, and determines a first slice corresponding to the first service description information based on the first service description information.

[0074] The traffic descriptor (TD) information is used to indicate one or more of the network protocol IP triplet, FQDN, APPID, and data network name (DNN).

[0075] The terminal device can determine the first service description information based on the first service requirement and the first correspondence relationship. The first correspondence relationship includes the correspondence between multiple parameter value ranges of the service requirement and multiple service description information. In the first correspondence relationship, the parameter value of the first service requirement belongs to the parameter value range corresponding to the first service description information.

[0076] For example, the first service requirement is a real-time uplink rate requirement. The first correspondence includes the correspondence between multiple parameter value ranges of the real-time uplink rate requirement and multiple service description information. For instance, the first correspondence includes two rate thresholds, denoted as R_TH1 and R_TH2, where R_TH1 > R_TH2. In the first correspondence, the rate value ranges are: R > R_TH1 corresponds to the first service description information; R_TH1 ≥ R ≥ R_TH2 corresponds to the second service description information; and R < R_TH2 corresponds to the third service description information. If the terminal device determines that the rate value R1 > R_TH1 of the first service requirement falls within the rate value range corresponding to the first service description information, then the terminal device determines the service description information corresponding to this first service requirement as the first service description information.

[0077] After determining the first service description information, the terminal device can determine the first slice corresponding to the first service description information according to the User Equipment Routing Selection Policy (URSP). The process of the terminal device determining the slice based on service requirements can be as follows: Figure 3 As shown, after the terminal device determines the first slice that meets the first service requirement, it can establish a slice pipeline based on the selected first slice. This allows the terminal device and network devices to transmit the service data of that service through the established slice pipeline.

[0078] The network device can send third configuration information to the terminal device. Correspondingly, the terminal device receives the third configuration information from the network device. This third configuration information is used to configure a User Routing Policy (URSP). The URSP configured by the third configuration information includes the correspondence between multiple service description information and multiple slices, with one service description information corresponding to one slice. The terminal device can determine the first slice corresponding to the first service description information based on the first service description information and the URSP.

[0079] In another implementation, the terminal device determines multiple slices corresponding to the first service description information based on the first service description information. Then, based on the first service requirement, it determines the first slice among the multiple slices that meets the first service requirement.

[0080] In other words, in this embodiment, the service description information can correspond to multiple slices that can meet different service requirements. The terminal device can determine multiple slices corresponding to the first service description information based on the first service description information, and then determine the first slice that meets the first service requirement from among the multiple slices according to the first service requirement.

[0081] Optionally, in the multiple slices corresponding to the first business description information, each slice corresponds to a parameter value range of the business requirement, and the parameter value of the first business requirement belongs to the parameter value range corresponding to the first slice.

[0082] For example, the first service requirement is a downlink latency requirement. Each of the multiple slices corresponds to a latency range, such as the latency D for the first slice being in the range D_TH1 ≤ D ≤ D_TH2, the latency D for the second slice being in the range D < D_TH1, and the latency D for the third slice being in the range D > D_TH2. The terminal device determines the first slice that satisfies the latency requirement D1 based on the fact that the latency requirement D1 of the first service requirement falls within the range D_TH1 ≤ D ≤ D_TH2. In this embodiment, the process of the terminal device selecting a slice based on the service requirement can be as follows: Figure 4 As shown, after the terminal device determines the first slice that meets the first service requirement, it can establish a slice pipeline based on the selected first slice. This allows the terminal device and network devices to transmit the service data of that service through the established slice pipeline.

[0083] For example, the first service requirement includes real-time rate requirements and security isolation requirements. Each of the multiple slices corresponds to a range of real-time rate values ​​and a security isolation requirement. For instance, the first slice corresponds to a real-time rate R value range of R > R_TH and no security isolation requirement; the second slice corresponds to a real-time rate R value range of R > R_TH and a security isolation requirement; the third slice corresponds to a real-time rate R value range of R ≤ R_TH and no security isolation requirement; and the fourth slice corresponds to a real-time rate R value range of R ≤ R_TH and a security isolation requirement. The terminal device determines the first slice that satisfies the first service requirement based on the real-time rate requirement R1 > R_TH and the absence of a security isolation requirement.

[0084] The network device can send second configuration information to the terminal device. Correspondingly, the terminal device receives the second configuration information from the network device. This second configuration information is used to configure a User Routing Policy (URSP). The URSP configured in the second configuration information indicates the slice corresponding to each of multiple service descriptions, where one service description corresponds to multiple slices. The terminal device can determine the multiple slices corresponding to the first service description based on the first service description and the URSP.

[0085] S203, the terminal device establishes a slice pipeline for the first slice, which is used to transmit the service data of the service.

[0086] After the terminal device establishes the slice tunnel for the first slice, the terminal device and network devices can transmit the service data for that service through this slice tunnel. This ensures that the slice tunnel established by the terminal device can meet the service requirements.

[0087] The solution proposed in this application allows terminal devices to select slices that meet the service requirements based on the service needs of the business and establish corresponding slice pipelines. This method of selecting slices can meet differentiated service needs and improve the efficiency of network resource utilization.

[0088] The slice selection method provided in this application has been described above with reference to the accompanying drawings. The slice selection device and communication equipment provided in this application will be described below.
