The base station (NodeB) in Wideband Code Division Multiple Access (W-CDMA) can also be an evolved base station (NodeB or eNB or e-NodeB, evolutional NodeB) in Long Term Evolution (LTE). This application does not Not limited.

SSF, or SSF Access Management Function (SSF-AMF), is used to select slices.

Wherein, the slice selection auxiliary information may be a slice ID (Slice IDetification) or a network slice ID (Network Slice IDetification, Nes-ID).

The service type can also be referred to as a service type, which is used to distinguish a certain type of service, for example, it is used to indicate service types such as eMBB service, URLLC service, and mMTC service. Each business type has a corresponding business type identifier. One network slice can correspond to one service type, and there are multiple network slices under one service type, so there is a mapping relationship between service types and network slices.

Optionally, the network slice information may also include information such as delay, bandwidth, jitter, wireless received signal strength, window size, reliability, and security.

In addition, each slice information may also contain other information items, which are not limited here.

Specifically, the at least one piece of network slice information may be preset in the terminal by a terminal manufacturer or a network operator, or may be obtained by the terminal device from a network device.

The network device can obtain the network slice information of the current network from the slice management system in the core network. For example, the slice management system delivers network slice information of the network to various network elements on the network side, including network elements such as AN, SSF, or CP, and the network elements such as AN, SSF, or CP store the network slice information of the current network.

Optionally, the terminal device stores the acquired network slice information of the current network. When the network slice information of the current network in the network device is updated (added, deleted, or modified), the network device can update the updated slice information Synchronize to the terminal device so that the terminal device can update the locally stored network slice information.

Optionally, the terminal device updates the at least one piece of network slice information stored in the terminal device when detecting that the location of the terminal device is updated; or periodically updates the information stored in the terminal device The at least one network slice information.

Specifically, in different location areas, network devices may be different, and the corresponding network slice information of the current network may also be different. Therefore, when the terminal device detects that the location area of the terminal device has changed, the terminal device can pass the network device Update the locally stored network slice information. Alternatively, the terminal device may also periodically update the locally stored network slice information through the network device by setting an aging time, where the aging time is the period of time.

In the embodiment of the present application, the terminal device acquiring the hardware information of the terminal device may include, but is not limited to, directly reading the specific hardware parameter information stored in the system of the terminal device, or through the terminal identification of the terminal device from the network or Obtained from the cloud.

The service flow characteristic information refers to the service flow information corresponding to the service selected by the user on the terminal device or the service automatically operated by the terminal itself.

For example, if a user plays a live video in a video application installed on a terminal device, the terminal device receives a video service selection instruction input by the user, and determines the delay condition, bandwidth condition, jitter condition, and security corresponding to the video service according to the instruction. And other information.

303: The terminal device determines target network slice information in the at least one network slice information according to the current service flow characteristic information and the hardware information.

As an optional implementation manner, the terminal device determines the target network slice information in the at least one piece of network slice information according to the current service flow characteristic information and the hardware information, which may specifically include: the terminal device according to the current service The flow characteristic information and the hardware information determine the type of the target network slice; then according to the current service flow characteristic information and the hardware information, the demand information of the target network slice is determined, and the demand information includes at least one demand parameter and the at least one demand parameter. The parameter content of a request parameter; finally, the target slice information is selected from the at least one network slice information according to the type of the target network slice and the request information of the target network slice.

Wherein, the request parameter may specifically include but is not limited to at least one of delay, bandwidth, jitter, etc., and the content of the parameter may be a certain value or a range, or a byte description.

Optionally, the terminal device determining the type of the target network slice according to the current service flow characteristic information and the hardware information may specifically include: the terminal device determining the network slice supported by the terminal device according to the hardware information Then, according to the current service flow characteristic information, determine the type of network slice that supports the current service flow; finally, according to the type of network slice supported by the terminal device and the network that supports the demand of the current service flow The type of slice determines the type of the target network slice.

In a specific implementation, different terminals can support different types of network slices, and different services have different requirements for the types of slices. Therefore, the type of the target network slice can be determined from two aspects: the type of the network slice supported by the terminal device and the type of the network slice supporting the requirements of the current service flow. The type of network slice supported by the terminal device can be determined according to the hardware information of the terminal device currently in use. The type of the network slice that supports the requirements of the current service flow may be determined according to the specific service flow characteristic information corresponding to the current service. Finally, by taking the intersection of the obtained results of the two types of network slicing, the type of the target network slicing can be obtained.

For example, terminal devices support different business forms according to hardware differences, such as drones, VR/AR glasses, autonomous driving, wearable devices, and smart phones. Different devices have different support capabilities and require different types of slices. , UAVs are mainly video shooting/returning, which requires low latency and large bandwidth requirements, while the low latency type required for automatic driving. Therefore, we need to negotiate network slicing requirements based on the capabilities of different devices to achieve self-adaptation, automatic scheduling algorithms, and convenient and quick use.

Further, the terminal device determining the type of network slice supported by the terminal device according to the hardware information may specifically include:

(1) The terminal device determines the hardware feature vector of the terminal device according to the hardware information;

(2) The terminal device calculates the distance between the hardware feature vector and the first reference vector to obtain the first distance, where the first reference vector is a network slice of a massive IoT service type in the first spatial coordinate system If the first distance is less than a first threshold, it is determined that the terminal device supports network slices of massive IoT service types; if the first distance is less than a first threshold, the first spatial coordinate system is the spatial coordinate system where the hardware feature vector is located;

(3) The terminal device calculates the distance between the hardware feature vector and the second reference vector to obtain the second distance, where the second reference vector is the network slice of the enhanced mobile broadband service type in the first space The reference vector in the coordinate system; if the second distance is less than the second threshold, it is determined that the terminal device supports the network slice of the enhanced mobile broadband service type;

In a specific implementation, a multi-dimensional first spatial coordinate system may be formed based on the hardware parameters included in the hardware information, and the hardware information of each terminal device may be represented by a hardware feature vector in the first spatial coordinate system. In addition, it is also possible to determine a reference vector for the type of each network slice in the first spatial coordinate system through the corresponding relationship between the type of each network slice and the hardware information.
