In the prior art, the terminal can obtain corresponding service resources by sending service request information to the MEC server. After the MEC server receives the service request information from the terminal device, the MEC server will first judge whether it can provide the service resource. If the MEC server cannot provide the service resource, it will forward the service request information to the next-level MEC server. In order for the lower-level MEC server to determine whether it can provide the required service resources for the terminal device, the execution actions of the lower-level MEC server are similar to those of the MEC server.

In the above process, since the MEC server first needs to judge whether it provides service resources, it will forward the service request information to the next-level MEC server only if it does not exist. This will cause multi-level MEC servers to be unable to provide the service resources required by the terminal equipment. Each MEC server needs to first determine whether it can provide the service resources required by the terminal equipment provider, so that the terminal equipment can obtain the required service resources. The delay is long, which affects the user experience.

In order to solve the problem in the prior art that the terminal obtains service resources through the MEC server with too high time delay, the present application provides a MEC service scheduling method.

As shown in FIG. 2 , a MEC service scheduling method provided by the embodiment of the present application is applied to a first MEC server, and the first MEC server is any MEC server 102 in the communication system 10 shown in FIG. 1 , The method includes the following steps:

S201. The preset device sends first service request information to the first MEC server. Correspondingly, the first MEC server receives the first service request information sent by the preset device.

Wherein, the first service request information is used to request the first service resource. The preset device is a terminal or an upper-level MEC server of the first MEC server in the communication system.

In a possible implementation manner, the first service request includes at least one of a data service request and a processing service request.

Specifically, the data service request is used to request a corresponding data resource, for example, the corresponding data resource may be a video resource, an audio resource, a picture resource, a text resource, and the like.

Processing service requests are used to request corresponding processing resources. For example, the corresponding processing resources may be the processing resources required for modeling and rendering in augmented reality (AR), or may be the processing resources required for modeling and rendering in virtual reality (VR). The processing resources required.

S202. The first MEC server forwards the first service request information to the second MEC server. Correspondingly, the second MEC server receives the first service request information forwarded by the first MEC server.

Wherein, the second MEC server is a lower-level MEC server of the first MEC server in the communication system.

It should be noted that, in the embodiment of this application, after receiving the first service request information, the first MEC server will directly forward the first service request information to the next-level MEC server, so that the next-level MEC server The first service request information can be received in time and corresponding operations can be performed.

S203. The first MEC server determines whether the first service resource exists in the first MEC server.

Exemplarily, when the first service resource is a data resource, the first MEC server judges whether it stores the corresponding data resource. When the first service resource is a processing resource, the first MEC server judges whether it has an application for processing related services.

If the first service resource does not exist in the first MEC server, the first MEC server executes S204.

S204. The second MEC server sends the first service resource to the first MEC server. Correspondingly, the first MEC server receives the first service resource sent by the second MEC server.

In a possible implementation manner, the first service resource includes at least one of a data resource and a processing resource.

Wherein, the data resource corresponds to the data service request, and the processing resource corresponds to the processing service request. The first service resource may be a service resource existing in the second MEC server, or the first service resource may be a service resource received by the second MEC server and sent from another MEC server.

S205. The first MEC server forwards the first service resource to the preset device. Correspondingly, the preset device receives the first service resource forwarded by the first MEC server.

In a possible implementation, after step S205, the method further includes S206:

S206. The first MEC server stores the first service resource.

It should be noted that after the first MEC server stores the first service resource, when the preset device sends the first service request information to the first MEC server, the first MEC server can provide the preset device with the corresponding first service resource , thereby reducing the delay of MEC service scheduling.

Exemplarily, when the first service resource is a data resource, the first MEC server may store the resource in a memory. When the first service resource is a processing resource, the first MEC server may load an application for processing related services.

Based on the above technical solution, after receiving the first service request information sent by the preset device, the first MEC server directly forwards the first service request information to the next-level MEC server, and then judges whether it can provide the corresponding If the first service resource cannot be provided, wait for the next-level MEC server to send the first service resource, and send the first service resource to the preset device. In this way, the first MEC server can send the first service request information to the next-level MEC server in a timely manner, so that the next-level MEC server can respond to the first service request information more quickly, reducing MEC service scheduling. The delay improves the user experience.

Hereinafter, in conjunction with the above step S203, in the case that the first service resource exists in the first MEC server, the service scheduling method of the first MEC server will be specifically introduced.

As a possible embodiment of the present application, referring to FIG. 2, as shown in FIG. 3, after the above step S203, the following steps S301-S302 are specifically included:

S301. In a case where the first service resource exists in the first MEC server, the first MEC server sends the first service resource to the preset device. Correspondingly, the preset device receives the first service resource sent by the first MEC server.

Exemplarily, when the first service resource is a data resource, the first MEC server determines that it has stored the corresponding data resource, and sends the corresponding data resource to the preset device.

When the first service resource is a processing resource, the first MEC server determines that it has an application for processing related services, the first MEC server processes the first service request information through the service application, and sends the obtained processing resource to the preset device .

S302. The first MEC server sends first service request termination information to the second MEC server. Correspondingly, the second MEC server receives the first service request termination information sent by the first MEC server.

Wherein, the first service request termination information is used to request the second MEC server to stop processing the first service.

It should be understood that when the first MEC server judges that it can provide the first service resource corresponding to the first service request information, it does not need to obtain the service resource from the next-level MEC server. The level MEC server sends the first service request termination information to request the next level MEC server to stop processing the first service.

Based on the above technical solution, after the first MEC server determines that it can provide the corresponding first service resource, it sends the corresponding first service resource to the preset device, and sends the first service request termination information to the next-level MEC server to Requesting the lower-level MEC server to stop processing the first service avoids performance waste generated by the lower-level MEC server.
