At present, in a mobile edge computing scene, user equipment accesses an edge computing power node, and the edge computing power node provides computing power service for a user. However, in a scenario where the ue is moving continuously, if the ue moves to a position far away from the edge computing power node, the quality of service of the edge computing power node for providing computing power service to the user will be reduced. Existing solutions typically switch the user device from a primary edge computing power node (denoted as a first edge computing power node) to a closer edge computing power node (denoted as a second edge computing power node). And the computing power service of the user equipment is still processed on the first edge computing power node, and the second edge computing power node is used as a transfer node for forwarding a processing result and a task to be processed. However, this method will increase the delay of the edge node in processing the computing service and reduce the quality of the computing service provided by the edge node.
In order to solve the problems in the prior art, the present application provides a computing power service switching method, which can determine whether a second edge computing power node provides a computing power service for a user equipment by judging whether the second edge computing power node supports a first computing power service provided by a first edge computing power node for the user equipment and whether a service delay of the second edge computing power node is smaller than a service delay of the first edge computing power node, when the user equipment is close to the second edge computing power node. Therefore, under the condition that the second edge computing power node supports the first computing power service and the service delay is smaller than that of the first edge computing power node, the second edge computing power node continuously provides the network access service and the first computing power service for the user equipment, so that the user equipment is switched to the second edge computing power node, the time delay of the computing power service at the edge computing power node is further reduced, and the quality of the computing power service provided by the edge computing power node for the user is improved.
The computing power service switching scheme provided by the embodiment of the application can be applied to the electronic equipment shown in fig. 1. The electronic device related to the embodiment of the present application may be an edge computing node shown in fig. 2, or a computing network management system, or may be a newly added independent device, which is not limited in this application.
The method and the device aim to solve the problem that user equipment cannot be effectively switched when computing power service is provided for the user equipment in the prior art. As shown in fig. 3, the computing power service switching method provided by the present application includes the following steps:
s301, the electronic equipment receives first indication information from the first edge force calculation node.
In one possible implementation, the electronic device is taken as an example of the second edge force calculation node.
The first indication information is used for indicating the second edge computational power node to judge whether the second edge computational power node supports the first computational power service or not, and the first edge computational power node is an edge computational power node which provides the first computational power service for the user equipment.
Optionally, when the distance between the user equipment and the second edge calculation force node is less than or equal to the preset distance, the second edge calculation force node sends first request information to the first edge calculation force node, where the first request information is used to instruct the first edge calculation force node to send first instruction information to the second edge calculation force node.
After that, the first edge force calculation node feeds back the first indication information to the second edge force calculation node according to the received first request information.
It should be noted that, in practical applications, the preset distance may be set manually, which is not limited in the embodiments of the present application.
S302, the electronic equipment judges whether the second edge computing power node supports the first computing power service.
Optionally, the determining whether the second edge computation force node supports the first computation force service may specifically be divided into the following four cases:
in case one, the second edge computing power node has a non-network reason that the first computing power service is not supported.
The non-network reason that does not support the first computing service may include: hardware does not support, rules are preset manually and limits, etc.
In this case, the electronic device determines that the second edge computing force node does not support the first computing force service.
And in case two, the second edge computing power node has no non-network reason which does not support the first computing power service, and the computing power service operated by the second edge computing power node comprises the first computing power service.
In this case, the electronic device determines that the second edge computing force node supports the first computing force service.
And in case III, the second edge computing power node does not have a non-network reason which does not support the first computing power service, and the computing power service operated by the second edge computing power node does not comprise the first computing power service, but the second edge computing power node has enough resources for deploying the first computing power service.
In this case, the electronic device determines that the second edge computing force node supports the first computing force service.
It should be noted that the existence of sufficient resources in the second edge computation force node may include: (1) and idle resources exist in the second edge computing power node, and the idle resources can meet the requirement of deploying the first computing power service. (2) And after the second edge computing power node stops the idle computing power services, the released resources can meet the requirement of deploying the first computing power service.
And in case four, the second edge computing power node has no non-network reason which does not support the first computing power service, the computing power service operated by the second edge computing power node does not comprise the first computing power service, and the second edge computing power node also does not have enough resources for deploying the first computing power service.
In this case, the electronic device determines that the second edge computing force node does not support the first computing force service.
Optionally, in a case that the electronic device determines that the second edge computing power node supports the first computing power service, the subsequent step S303 is executed.
S303, the electronic equipment determines the service time delay of the first edge computational force node and the service time delay of the second edge computational force node.
Optionally, the first indication information received by the electronic device includes service state information of the first computing service. Further, the service state information includes service delay of the first edge computation force node.
In one possible implementation, the service state information of the first computing service is carried in a user snapshot of the first computing service, where the user snapshot includes all service states of the first computing service (including but not limited to service latency of the first computing service). Specifically, after the first edge computing power node receives the first service request of the second edge service node, the first edge computing power node takes a snapshot of the current state of the user service of the first computing power service, and carries the snapshot information in the first indication information to send to the second edge computing power node.
It can be understood that the first edge computing power node may also send the user snapshot of the first computing power service to the second edge computing power node separately, and is not carried in the first indication information.
It should be noted that the service delay T of a certain edge computing power node for a computing power service specifically consists of a wireless channel delay T1 and a wired channel delay T2, that is, T1+ T2. The wireless channel delay T1 is the delay of the wireless communication between the ue and the edge computing node, and the specific method for obtaining the delay is the prior art, which is not described herein again.
Illustratively, in each edge computation force node, an edge computation force node service delay table is maintained, and the table is dynamically updated, and can reflect the wired channel delay of the current edge computation force node and each other edge computation force node in the computation force network for a certain computation force service. For example, table 1 below shows specific data of service delay of a certain edge force computing node and other edge force computing nodes:
TABLE 1 service delay table of edge force node
| Computing force service ID | Wired channel delay T2(ms) | Service delay object node |
| c0018764 | 90 | N1 |
| c00872655 | 66 | N7 |
| c0044875 | 0 | L |
Note that in table 1, N1 and N7 represent other edge computation force nodes, and L represents the edge computation force node itself (i.e., the time delay between the edge computation force node and itself is 0).
It will be appreciated that, by way of the above example, each edge computing force node in the computing force network is able to determine its own wireless channel delay T1 and wired channel delay T2, and thus its own service delay.
It should be noted that, if a certain edge computation force node supports the first computation force service, the service delay of the edge computation force node at this time is the wireless channel delay of the edge computation force node.
By the example, the electronic device can acquire and compare the service time delays of the first edge calculation power node and the second edge calculation power node. If the service delay of the second edge computation force node is smaller than the service delay of the first edge computation force node, the following step S304 is executed.
S304, the electronic equipment provides network access service and the first computing power service for the user equipment.
In one possible implementation, the electronic device is taken as an example of the second edge force calculation node. Correspondingly, the user equipment is switched to the second edge computational power node at the moment, and the second edge computational power node is the user equipment.
Optionally, corresponding to the example in step S303, the first indication information received by the second edge computation force node includes a user snapshot of the first computation force service, and the second edge computation force node can copy the user state to the local according to the user snapshot, so that the user equipment is seamlessly switched to the second edge computation force node to use the first computation force service.
Based on the above technical solution, in the embodiment of the present application, when the ue is close to the second edge computing power node, whether the second edge computing power node supports the first computing power service provided by the first edge computing power node for the ue, and whether the service delay of the second edge computing power node is smaller than the service delay of the first edge computing power node is determined, so as to determine whether the second edge computing power node provides the computing power service for the ue. Therefore, under the condition that the second edge computing power node supports the first computing power service and the service delay is smaller than that of the first edge computing power node, the second edge computing power node continuously provides the network access service and the first computing power service for the user equipment, so that the user equipment is switched to the second edge computing power node, the time delay of the computing power service at the edge computing power node is further reduced, and the quality of the computing power service provided by the edge computing power node for the user is improved.
With reference to fig. 3, as shown in fig. 4, in the case that the service delay of the second edge computation power node is greater than or equal to the service delay of the first edge computation power node, the computation power service switching method provided in the present application further includes the following steps:
s401, the electronic equipment keeps the first edge computing power node to provide the first computing power service for the user equipment.
In one possible implementation, the electronic device is taken as an example of the second edge force calculation node.
It can be understood that, in this case, it indicates that although the second edge computing power node supports the first computing power service, since the service delay of the second edge computing power node is greater than or equal to the service delay of the first edge computing power node, the first edge computing power node may maintain the computing power service with the user equipment without switching the user equipment.
With reference to fig. 3, as shown in fig. 5, in a case that a second edge computing power node does not support the first computing power service, the computing power service switching method provided in the present application further includes the following steps:
s501, the electronic equipment judges whether the service delay of the second edge force computing node is smaller than that of the first edge force computing node.
In one possible implementation, the electronic device is taken as an example of the second edge force calculation node.
Optionally, if the service delay of the second edge computation force node is greater than or equal to the service delay of the first edge computation force node, the subsequent step S502 is executed.
Optionally, if the second edge computation force node does not support the first computation force service, and the service delay of the second edge computation force node is smaller than the service delay of the first edge computation force node, the subsequent step S503 is executed.
S502, the electronic equipment keeps the first edge computing power node to provide the first computing power service for the user equipment.
In one possible implementation, the electronic device is taken as an example of the second edge force calculation node.
It can be understood that, in this case, it indicates that the second edge computational power node does not support the first computational power service, and the service delay is also greater than or equal to the service delay of the first edge computational power node, and at this time, the first edge computational power node does not need to perform handover and the first edge computational power node maintains the computational power service with the user equipment.
S503, the electronic equipment provides network access service for the user equipment, and sends user snapshots of the first computing power service to the third edge computing power node.
In one possible implementation, the electronic device is taken as an example of the second edge force calculation node.
And the third edge calculation force node is an edge calculation force node which has the minimum communication time delay with the second edge calculation force node in the edge calculation force nodes supporting the first calculation force service. The determination method of the service delay of the third edge calculation power node and the determination method of whether the first calculation power service is supported are the same as those described in the foregoing step S303, and are not described herein again.
It should be noted that, at this time, although the second edge calculation force node does not support the first calculation force service, since the service delay of the second edge calculation force node is minimum, the second edge calculation force node provides a network access service for the user equipment, and the second edge calculation force node transfers the service data of the first calculation force service of the third edge calculation force node, and forwards the service data of the first calculation force service to the user equipment, so that the delay when the edge calculation force node provides the calculation force service for the user is minimum.
It can be understood that, in the case where the service delay of the first edge computation force node is minimal, the third edge computation force node at this time is the same node as the first edge computation force node. Accordingly, the user equipment need not switch nodes for the first computing service.
Optionally, the second edge computation force node enables the third edge computation force node to obtain data of the user equipment by sending the user snapshot of the first computation force service to the third edge computation force node, so that the user equipment is seamlessly switched to the third edge computation force node to use the first computation force service.
The computing power service switching method provided by the present application is specifically described above.
The following describes an exemplary handover procedure of the computing power service with reference to a specific example.
As shown in fig. 6, the algorithm network includes nine edge algorithm nodes N1-N9, the user equipment initial access node is N1, and the user equipment moves from N1 to N7. The following description is made in conjunction with three scenarios (scenario a, scenario B, and scenario C):
(1) for scenario a, the computational network satisfies the following conditions:
condition one, edge computing force nodes N1, N7 support computing force service c00872655, and N9 supports computing force service c 00872655.
The wireless communication delays of the conditions two, N1, N9 and N7 and the user equipment are 50ms, 20ms and 90ms respectively.
And in the third condition, for the force computing service c00872655, the communication delay of the wired channel between N1 and N9 is 20ms, and the communication delay of the wired channel between N7 and N9 is 10 ms.
And the condition four does not consider other nodes except N1, N7 and N9 for the moment.
In scenario a, since N9 supports the computing power service c00872655, it is easy to obtain that the service delays of N1, N7, and N9 at this time are:
the service latency of N1 is: t isN1＝50ms；
The service latency of N7 is: t isN7＝90ms；
The service latency of N9 is: t isN9＝20ms。
Due to TN9＜TN1＜TN7Therefore, the ue switches to N9, and continues to be provided with the network access service and the power service c00872655 by N9.
(2) For scenario B, the computational network satisfies the following conditions:
condition one, edge computing force nodes N1, N7 support computing force service c00872655, and N9 does not support computing force service c 00872655.
The wireless communication delays of the conditions two, N1, N9 and N7 and the user equipment are 50ms, 20ms and 90ms respectively.
And in the third condition, for the force computing service c00872655, the communication delay of the wired channel between N1 and N9 is 20ms, and the communication delay of the wired channel between N7 and N9 is 10 ms.
And the condition four does not consider other nodes except N1, N7 and N9 for the moment.
In scenario B, since N9 does not support the computation force service c00872655, it is easy to obtain that the service delays of N1, N7, and N9 at this time are:
the service latency of N1 is: t isN1＝50ms；
The service latency of N7 is: t isN7＝90ms；
The service latency of N9 is: t isN9＝20ms+10ms＝30ms。
Due to TN9＜TN1＜TN7Therefore, the network access service is provided for the user equipment by the N9, that is, the user equipment accesses the N9 at this time, but the computing power service c00872655 is provided by the N7, and the N9 is only used as a network access node and a data forwarding node of the computing power service c 00872655.
(3) For scenario C, the computational network satisfies the following conditions:
condition one, edge computing force nodes N7, N8 support computing force service c00872655, and N9 does not support computing force service c 00872655.
And under the second condition, the user equipment continues to move, the network access is stopped with the N1, and the wireless communication time delays of the N7, the N8 and the N9 with the user equipment are respectively 70ms, 20ms and 25 ms.
And in the third condition, for the force computing service c00872655, the communication delay of the wired channel between N1 and N9 is 20ms, the communication delay of the wired channel between N7 and N9 is 10ms, and the communication delay of the wired channel between N8 and N9 is 5 ms.
And the condition four does not consider other nodes except N1, N7, N8 and N9 for the moment.
In scenario C, since N9 does not support the computationally intensive service C00872655, it is easy to obtain that the service latencies of N1, N7, N8, and N9 at this time are:
the service latency of N7 is: t isN7＝70ms；
The service latency of N8 is: t isN8＝20ms；
The service latency of N9 is: t isN9＝25ms+5ms＝30ms。
Due to TN8＜TN9＜TN7By usingThe user equipment switches to N8, and the network access service and the power service c00872655 are continuously provided for the user equipment by N8.
