Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a scheduling method and apparatus.
Background
In recent years, virtual reality technology has received increased acceptance. Virtual reality technology requires rendering. In the prior art, rendering methods used in virtual reality technologies are generally classified into: native rendering and cloud rendering. The local rendering is three-dimensional (3D) rendering by using the resources of the device itself, and requires a higher performance of the device. Cloud rendering refers to rendering by using a special rendering server, and then transmitting the rendered image to a terminal, and requires a relatively low time delay between the terminal and the rendering server.
Most of existing cloud rendering systems have multiple rendering servers, and the cloud rendering systems generally allocate rendering servers nearby for terminals with rendering requirements, however, the nearby allocated rendering servers are not necessarily the rendering servers with the lowest time delay between the multiple rendering servers of the rendering systems and the terminals with the rendering requirements, and therefore, the optimal service may not be provided for users, and user experience is affected.

And then, determining a first target rendering server according to a pre-stored network architecture of the rendering server cluster, the area where the terminal is located and the target service. Then, the first message is sent to the terminal. Finally, a second message is sent to the first target rendering server. The service application comprises a target service and a region where the terminal is located. The target service is a service to be applied by the terminal. The first target rendering server is the rendering server with the lowest time delay between the second target rendering server and the terminal. The second target rendering server is a server in the rendering server cluster which can provide the target service. The first message is used for indicating the terminal to be connected with the first target rendering server. The second message is used for instructing the first target rendering server to provide the target service to the terminal.
Since the delay is related to the distance from end to end in the network architecture, the shortest distance from end to end in the network architecture is not necessarily the shortest physical distance from end to end. Therefore, the existing scheduling method allocates rendering servers to the terminals only according to the physical distance between the terminals and the rendering servers, and may not allocate rendering servers with the lowest time delay to the terminals. Instead of allocating rendering servers to terminals by physical distance between the terminals and the rendering servers, the present invention allocates rendering servers to terminals according to a network architecture. Therefore, compared with the existing scheduling method, the probability of allocating the rendering server with the lowest time delay to the terminal can be improved, and the problem of how to allocate the rendering server with the lowest time delay to the terminal can be solved.

And the first sending unit is used for sending a first message to the terminal, wherein the first message is used for indicating the terminal to be connected with the first target rendering server. And the second sending unit is used for sending a second message to the first target rendering server, wherein the second message is used for indicating the first target rendering server to provide the target service for the terminal.

Optionally, the service application may further include: and (4) user information.
After receiving the service application reported by the terminal, the scheduling device 100 may verify whether the service application is complete and verify whether the user corresponding to the user information in the service application has an application right.
When the service application is incomplete or the user corresponding to the user information in the service application does not have an application right, the scheduling device 100 may refuse to allocate a rendering server to the terminal and return a failure response to the terminal, where the failure response may include a service application failure reason (e.g., the service application is incomplete, no application right, etc.).
Alternatively, the scheduling apparatus 100 may periodically acquire the resource list in each rendering server from the rendering server cluster.
S402, the scheduling device 100 determines a first target rendering server according to a pre-stored network architecture of the rendering server cluster, a terminal located area and a target service.
And the first target rendering server is the rendering server with the lowest time delay between the second target rendering server and the terminal.
The second target rendering server is a server in the rendering server cluster which can provide the target service.
Specifically, S402 may include:
the scheduling device 100 determines a first target rendering server cluster according to a pre-stored network architecture of the rendering server cluster, a terminal located area and a target service.
And the first target rendering server cluster is the rendering server cluster with the lowest time delay between the second target rendering server cluster and the terminal. The second target rendering server cluster is a rendering server cluster which can provide target service in the rendering server clusters.
It is worth mentioning that the scheduling apparatus 100 may determine whether the rendering server (rendering server cluster) can provide the target service according to the resource list in the rendering server.
Specifically, the scheduling device 100 determines a first target rendering server cluster according to a pre-stored network architecture of the rendering server cluster, a region where the terminal is located, and the target service. The method can comprise the following steps:
the scheduling device 100 determines a base station side rendering server cluster of the terminal, an area side rendering server cluster of the terminal, a core side rendering server cluster of the terminal, and a cross-area side rendering server cluster of the terminal according to a pre-stored network architecture of the rendering server cluster and an area where the terminal is located.
The scheduling device 100 determines that the base station side rendering server cluster of the terminal is the first target rendering server cluster when the base station side rendering server cluster of the terminal can provide the target service.
The scheduling device 100 determines that the area-side rendering server cluster of the terminal is the first target rendering server cluster when the base-station-side rendering server cluster of the terminal cannot provide the target service and the area-side rendering server cluster of the terminal can provide the target service.
The scheduling device 100 determines that the core-side rendering server cluster of the terminal is the first target rendering server cluster under the condition that the base-side rendering server cluster of the terminal cannot provide the target service, the area-side rendering server cluster of the terminal cannot provide the target service, and the core-side rendering server cluster of the terminal can provide the target service.
The scheduling device 100 determines that the cross-regional rendering server cluster of the terminal is the first target rendering server cluster under the condition that the base station rendering server cluster of the terminal cannot provide the target service, the regional rendering server cluster of the terminal cannot provide the target service, the core rendering server cluster of the terminal cannot provide the target service, and the cross-regional rendering server cluster of the terminal can provide the target service.

The scheduling apparatus 100 determines a first target rendering server from a first cluster of target rendering servers.
Specifically, when only one second target rendering server exists in the first target rendering server cluster, it is determined that the second target rendering server in the first target rendering server cluster is the first target rendering server.
And under the condition that a plurality of second target rendering servers exist in the first target rendering server cluster, determining the second target rendering server with the lowest time delay between the second target rendering server and the terminal in the first target rendering server cluster as the first target rendering server.
S403, the scheduling device 100 sends a first message to the terminal.
The first message is used for indicating the terminal to be connected with the first target rendering server.
It is noted that the first message may include the address and the authentication information of the first target rendering server. Correspondingly, the terminal can carry identity authentication information and apply for the target service to the first target rendering server after passing identity authentication.
Under the condition that the service request further includes a time delay required by the target service, S403 specifically includes:
the scheduling device 100 sends the first message to the terminal when the delay between the terminal and the first target rendering server is less than the delay required by the target service.
Correspondingly, when the time delay between the terminal and the first target rendering server is larger than the time delay required by the target service, a failure response is returned to the terminal.
S404, the scheduling device 100 sends a second message to the first target rendering server.
And the second message is used for instructing the first target rendering server to provide the target service for the terminal.
It is noted that the second message may include the identity authentication information in the first message, so that the first target rendering server performs identity authentication on the terminal, and after passing the identity authentication, the first target rendering server provides the target service to the terminal.
When the service request further includes a time delay required by the target service, S404 is specifically:
the scheduling device 100 sends the second message to the first target rendering server when the delay between the terminal and the first target rendering server is smaller than the delay required by the target service.
It can be seen from S401-S404 that, in the embodiment of the present invention, the rendering server is allocated to the terminal according to the network architecture, rather than being allocated to the terminal by the physical distance between the terminal and the rendering server. Therefore, compared with the existing scheduling method, the probability of allocating the rendering server with the lowest time delay to the terminal can be improved, and the problem of how to allocate the rendering server with the lowest time delay to the terminal can be solved.
Referring to fig. 4, as shown in fig. 5, the scheduling method provided in the embodiment of the present invention may further include:
s405, the scheduling device 100 determines the type of the network slice required by the terminal according to the time delay required by the target service, the bandwidth required by the target service, the area where the terminal is located and the area where the first target rendering server is located.
Specifically, S405 may include:
the scheduling device 100 determines the delay type of the network slice required by the terminal according to the delay required by the target service.
The latency types of the network slice can be divided into high latency (500 milliseconds (ms)), medium latency (200ms) and low latency (70 ms).
The scheduling device 100 determines the bandwidth type of the network slice required by the terminal according to the bandwidth required by the target service.
Among them, the bandwidth types of the network slice may be divided into a high bandwidth (1000 megabits per second (Mbps)), a medium bandwidth (500Mbps), and a low bandwidth (200 Mbps).
The scheduling device 100 determines the region type of the network slice required by the terminal according to the region where the terminal is located and the region where the first target rendering server is located.
The region type of the network slice can be divided into a base station, a region and a core.
