Summary of the application
The 5G system abstracts the general physical resources into virtual resources, and then uses a core controller to cut and arrange the resources according to specific business requirements, so as to construct a plurality of customized virtual network slices. In practical deployment, dedicated slices need to be created for services with different requirements, and a 5G network architecture can have multiple virtual slices under the same base station, and resource allocation among slices becomes important.
The network slicing technology is to slice the physical network of the operator into a plurality of virtual networks, each network is adapted to different service requirements, and different networks can be divided through time delay, bandwidth, security and reliability so as to adapt to different scenes. On the same 5G network, operators can slice the network into a plurality of different networks such as intelligent transportation, unmanned aerial vehicle, intelligent medical treatment, intelligent home, industrial control and the like, and open the networks to different operators, so that the sliced network has different guarantees on bandwidth and reliability capability, and a charging system and a management system are also different.
In the next generation mobile communication network, the terminal side is not limited to the mobile phone and the PAD terminal any more, and more types of devices are gradually introduced into the communication network, such as AR/VR glasses, intelligent wearing, unmanned aerial vehicles, unmanned vehicles, and the like. Meanwhile, main service scenes represented by large-bandwidth mobile access, large-scale internet of things access and the like have also been solidified. The customized slice based on the service requirement can enable the 5G network to have good service adaptability and meet the requirements of differentiated QoS (Quality of Service ) among different services, such as time delay, mobility, reliability and the like. Therefore, the introduction of the network slicing technology will bring operators into the vertical business market with mass scale, and a core pushing effect is generated.
However, when the network slice fails or the service requirement of the terminal cannot be met, not only the position and the failure cause of the failure are detected in time, but also other slices are provided in time to ensure the continuous operation of the service, so that the influence of the failure on the service is reduced, otherwise, the service is easily interrupted, and the user experience is poor.
In view of the above technical problems, the present application provides a network switching method, apparatus, and computer readable storage medium, where network quality is often degraded before a network slice fails or cannot meet a terminal service requirement, so that by determining a degree of degradation of network quality and setting a corresponding threshold, and deploying a second network slice for a terminal before the network slice fails or cannot meet the terminal service requirement, and using the second network slice as a standby slice of the terminal, the terminal can switch to the second network slice in time before the network slice fails or cannot meet the terminal service requirement, thereby avoiding interruption of terminal service, and improving user experience.

In this embodiment, the target terminal may be a smart phone, a tablet computer, AR/VR glasses, smart wearable, unmanned vehicle, etc. that supports a 5G network. The source base station refers to a 5G base station where the target terminal is currently located. The service request may carry a terminal identifier, a slice identifier, a service identifier and slice configuration data, where the terminal identifier may be an IMSI (International Mobile Subscriber Identity ), the slice identifier is a slice identifier of a first network slice currently accessed by the target terminal, and the service identifier is used to identify a current service of the terminal, for example, the current service may be a voice service, a short message service, a web browsing service, an online video service, an online game service, an unmanned aerial vehicle service, and so on. The slice configuration data is slice configuration data of the first network slice, and may specifically include a quality of service QoS parameter and corresponding resource requirement information, where the resource requirement information includes a resource size required by the slice, and so on.
Optionally, the monitoring of the first network slice currently accessed by the target terminal according to the service request of the target terminal specifically includes:

In this embodiment, in order to preferentially ensure the requirement of the service with higher requirement on slicing, an important service may be preset, and the network resource requirement of the important service is preferentially ensured, so as to set a corresponding network slicing standby mechanism for the important service. Specifically, after receiving a service request of a target terminal, a source base station judges whether the current service of the target terminal is an important service according to a service identifier carried in the service request, and if so, the source base station monitors a first network slice in real time. The key services may be, for example, an online video service, an online game service, an unmanned aerial vehicle service, etc.

Specifically, when the source base station monitors that the network quality of the first network slice is reduced to a preset first threshold, a network slice standby flow is started, slice configuration data of the first network slice is sent to the target base station, so that the target base station configures a second network slice according to the slice configuration data to reserve corresponding resources for the terminal, and the target base station is preferably a 5G base station closest to the current position of the target terminal.
In this embodiment, when it is determined that the network quality of the first network slice is not degraded, or the degradation degree does not reach the preset first threshold, the target terminal continues to reside in the first network slice, and at the same time, the source base station continues to monitor the first network slice.

Specifically, when the source base station monitors that the network quality of the first network slice is reduced to a preset second threshold, a network switching instruction is sent to the target terminal, wherein the network switching instruction carries a slice identifier of the configured second network slice, so as to instruct the target terminal to switch to the second network slice. And the target terminal sends an access request to the target base station after receiving the network switching instruction, and the target base station accesses the target terminal into a second network slice according to the access request.
According to the network switching method provided by the embodiment, the source base station monitors the first network slice currently accessed by the target terminal according to the service request of the target terminal, when the condition that the network quality of the first network slice is reduced to the preset first threshold value is monitored, the slice configuration data of the first network slice is sent to the target base station, the target base station configures the second network slice according to the slice configuration data after receiving the slice configuration data, and the second network slice is used as a standby slice of the target terminal. When the source base station monitors that the network quality of the first network slice is reduced to a preset second threshold value, the source base station sends a network switching instruction to the target terminal, wherein the network switching instruction is used for indicating the target terminal to switch to the second network slice, so that the target terminal can be timely switched to the second network slice serving as a standby slice before the network slice breaks down or cannot meet the terminal service requirement, interruption of terminal service is avoided, user experience is improved, and the problems that service interruption is easy to cause and user experience is poor when the network slice breaks down or cannot meet the terminal service requirement in the related art are solved.

The source base station refers to a 5G base station where the target terminal is currently located. The slice configuration data may include quality of service QoS parameters of the first network slice and corresponding resource requirement information, such as a required resource size of the slice, etc.
In this embodiment, the first threshold is an early warning threshold, and for different types of services, different thresholds may be set according to different requirements for network quality, and when the network quality of the first network slice drops to a preset first threshold, the first network slice can currently meet the requirements of the services, but at this time, preparation of a standby network slice is required. Specifically, when the source base station monitors that the network quality of the first network slice is reduced to a preset first threshold value, a network slice standby flow is started, slice configuration data of the first network slice is sent to the target base station, and the target base station receives the slice configuration data sent by the source base station.
