Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

Currently, when initially applying for network slicing resources for different services, the terminal indicates the supported slicing services to the network, and through negotiation the network allocates corresponding slicing network resources according to the terminal’s subscription status, and the network resources obtained after the service runs This limit will not be exceeded and throughout the lifetime of the service. The traditional technology has at least the following problems: once the slice resource for service application is determined, if there is a new resource demand, it cannot be adjusted in time; if a slice temporarily needs to add some resources, it needs to be added to the original slice resource. Excessive allocation of slice resources can easily lead to waste of resources; even if the same service can share multiple slices, switching to a new network slice requires an application to the network, and there is a delay. For this reason, this application provides a network slicing resource sharing scheme, which can share sliced network resources obtained by low-priority services with high-priority services without initiating an application to the network, avoiding time delay and waste of resources, and improving resource utilization.

Referring to Fig. 1, the embodiment of the present application discloses a method for sharing network slicing resources, including:

Step S11: Obtain the resource application sent by the first service.

Step S12: Find the network slice resource corresponding to the resource application to obtain the target network slice resource.

In a specific implementation manner, the resource application includes the resource name of the required resource; correspondingly, the searching for the network slice resource corresponding to the resource application includes: searching for the network to which the required resource belongs based on the resource name Slice resources.

It can be understood that, in this embodiment of the present application, all available network slice resources and corresponding service names can be queried. The available network slicing resources are the network slicing resources that the corresponding service has applied for from the network.

Step S13: Compare the priorities of the second service corresponding to the target network slice resource with the first service.

In a specific implementation manner, the priority information of the second service may be searched, and the priorities of the second service and the first service may be compared based on the priority information obtained from the search.

Wherein, the priority can be customized by the user, specifically, the priority can be determined according to the importance of the service, the frequency of resource usage, and the degree of resource occupation when using the resource.

Step S14: When the priority of the first service is higher than that of the second service, query the running status of the target network slice resource.

Step S15: When the running state is idle, send the data to be sent of the first service by using the target network slice resource and the original network slice resource of the first service.

That is, when the running state of the target network slice resource is idle, it can be shared with the first service.

In a specific implementation manner, this embodiment of the present application may establish a temporary data channel between the first service and the first IP address; wherein, the first IP address is the IP address corresponding to the target network slice resource; determine the Describe the resource type required for the data to be sent; based on the resource type, use the temporary data channel to send the data to be sent through the first IP address, or use the original data channel to send the data to be sent through the The second IP address is sent; wherein, the second IP address is an IP address corresponding to the original network slice resource.

It should be pointed out that within the device, on the application side, that is, the service side, an IP address data channel corresponding to the service and network slice resources is established, and session processing is performed through the IP address to send data to the outside of the device.

That is to say, in the embodiment of this application, different network slice resources are obtained depending on different IP addresses, and the establishment of a temporary data channel realizes the binding with the corresponding network slice resource, so the temporary data channel can be established through dual IP address mapping By offloading the data corresponding to the service, without switching or re-applying, the corresponding network slicing resources can be obtained in time, achieving the effect of quickly sharing network slicing resources.

It can be seen that in the embodiment of the present application, the resource application sent by the first service is obtained first, and the network slice resource corresponding to the resource application is searched to obtain the target network slice resource, and then the second service corresponding to the target network slice resource is compared with The priority of the first service. When the priority of the first service is higher than that of the second service, query the running status of the target network slice resource. When the running status is idle, use the The target network slice resource and the original network slice resource of the first service send the data to be sent of the first service. In this way, obtain the resource application sent by the first service, find the corresponding target network slice resource, compare the priority of the second service and the first service, when the priority of the first service is higher than that of the second service, and the target network slice resource is idle, Then, the target network slice resource and the original network slice resource of the first service will be used to send the data of the first service, and the slice network resources obtained by the low-priority service can be shared with the high-priority service without initiating an application to the network, avoiding the Time delay and resource waste improve resource utilization.

Referring to Figure 2, the embodiment of the present application discloses a specific method for sharing network slicing resources, including:

Step S21: Obtain the resource application sent by the first service.

Wherein, the resource application includes the required usage time of the required resources.

Step S22: Find the network slice resource corresponding to the resource application to obtain the target network slice resource.

Step S23: comparing the priorities of the second service corresponding to the target network slice resource with the first service.

Step S24: When the priority of the first service is higher than that of the second service, query the operation status of the target network slice resource;

Step S25: When the running state is idle, send the data to be sent of the first service by using the target network slice resource and the original network slice resource of the first service.

It can be understood that the duration of the first timer is the required usage duration.

Step S26: Start a first timer based on the required usage duration, so as to control the duration of sending the to-be-sent data of the first service by using the target network slice resource.

It should be pointed out that there is no sequence between step S26 and the step of using the target network slice resource and the original network slice resource of the first service to send the data to be sent of the first service.

When the running state is connected, the target network slice resource is not used, or a first timer is started, and the running state of the target network slice resource is monitored in real time, and when the running state is detected to be idle, a second timer is started, If the first timer does not expire, then use the target network slice resource and the original network slice resource of the first service to send the data to be sent of the first service, when the first timer or the second timer expires , the target network slice resources are released.

Step S27: When obtaining the use request of the target network slice resource by the second service, suspend using the target network slice resource to send the data to be sent of the first service.

Step S28: When the second service enters the idle state again and the first timer has not timed out, continue to use the target network slice resource to send the data to be sent of the first service.

That is, in this embodiment of the present application, the first timer may be set, so as to release the temporary data channel after the first timer expires, release the binding with the IP address of the target network slice resource, and release the target network slice resource. Moreover, when the second service enters the idle state again, does not use the target network slice resource temporarily, and the first timer does not expire, the first service may continue to use the target network slice resource.

In a specific implementation manner, after the second service enters the idle state again, it further includes: starting a second timer;

Correspondingly, the continuing to use the target network slice resource to send the data to be sent of the first service includes: continuing to use the target network slice before the second timer or the first timer expires The resource sends the to-be-sent data of the first service.

In a specific implementation manner, when the second timer or the first timer expires, the resource of the target entire network slice is released.

In this way, the occupation time of the target network slice resource by the first service can be limited. In a specific implementation manner, the second service can be monitored, and the duration of the second timer can be determined based on the monitoring result. For example, based on the monitoring result, the first The second service needs to use the target network slice resource after 20 minutes, and the duration of the second timer can be set to a value less than 20 minutes. To avoid impact on the second service.

It can be seen that in the embodiment of this application, according to all the network slicing resources obtained by the device, relying on the priorities between different services, on the premise that high-priority services do not add new resource requirements for slicing, the original obtained network slicing In resources, network slice resources are shared on demand and time-sharing.

Taking the application scenario of full-scenario automatic driving as an example, the network slicing resource sharing solution of this application is further described:

In the first step, the car is driving on a wide road, and the autonomous driving service obtains low-latency and high-reliability network slicing resources.

In the second step, when the car enters the basement, due to the more complex terrain and poor network signal, the automatic driving service applies for wide connection slice resources, obtains the ultrasonic positioning device deployed in the basement, and the car communicates with each positioning device to simulate the basement form, for automatic driving.

In the third step, after the car leaves the basement, the terrain becomes wider again, and there is no need to communicate with each ultrasonic device, releasing wide-connection slice resources.
