Information for computing tasks includes one or any combination of the following:

List of types of computing tasks, computing power requirements of computing tasks;

The type list of the computing task includes: a single computing task type list, a multiple computing task type list;

The computing power requirement of the computing task includes one or any combination of the following: computing peak rate, computing capacity;

Step S202, the Internet of Vehicles service terminal determines whether the information of the computing task is supported, and if the information of the computing task is supported, a response message is sent to the task terminal of the Internet of Vehicles; if the information of the computing task is not supported, the information of the computing task is ignored. discovery request message;

The above response messages include but are not limited to: Discovery Response messages. In practical applications, other similar response messages may also be used to respond to the discovery request message.

Referring to FIG. 2A , FIG. 2A is a specific implementation scheme of the method provided in FIG. 2 in the scenario shown in FIG. 1B , as shown in FIG. 2A , the UE2 and UE3 are the Internet of Vehicles service terminals that support the information of the computing task , UE4 and UE5 are Internet of Vehicles service terminals that do not support the information of the computing task.

The priority is to select the service V2X terminal; if the amount of tasks unloaded to each service V2X terminal is different, the available computing power support and signal quality can be considered, and the service V2X terminal can be selected. This application does not limit the specific performance of the service V2X terminal. form.

The implementation method of the above step S204 may specifically include:

Under a single computing task requirement:

If a single service V2X terminal can meet the computing resource requirements, then the task V2X terminal mainly selects among the candidate service V2X terminals according to the channel quality. UE-4, UE-5 and UE-7 first exclude UE-5 that does not meet the computing power requirements, and then exclude UE-2, UE-3, UE-4 and UE-7 with poor signal quality. 4. Then select the one with the best signal quality to establish a connection. The evaluation method of signal quality can be RSRP, RSRQ, etc., so UE-1 can choose UE-2 or UE-7 to establish a PC5 connection, and then initiate subsequent operations such as task offloading.

If a single service V2X terminal does not meet the computing resource requirements, the task V2X terminal selects among the candidate service V2X terminals according to the channel quality and available computing resources.

Under the requirement of multiple computing tasks:

If a single service V2X terminal can meet the multi-task computing requirements at the same time, then the task V2X terminal mainly selects among the candidate service V2X terminals according to the channel quality;

If a single service V2X terminal cannot meet the multi-task computing requirements at the same time, you can refer to the implementation method if a single service V2X terminal does not meet the computing resource requirements under single-task computing requirements, process each computing task separately, and select an appropriate service V2X terminal The connection is established, and then the subsequent operations of task offloading are performed.

In the method shown in FIG. 2 , the combination of step S201 , step S203 and step S204 can be the implementation method on the IoV task terminal side, and step S202 can be the support method on the IoV service terminal side.

The technical solution provided by this application determines the surrounding IoV service terminals that support computing tasks by discovering the request message and the response message, and then selects the IoV service terminal that meets the computing task type and computing power requirements according to the signal quality to establish a connection, and performs subsequent uninstall operations. Therefore, the technical solution of the present application can realize the collection of feedback information for the computing task of the Internet of Vehicles service terminal by discovering the request message and the discovery response message, and then can select a matching Internet of Vehicles service terminal. Therefore, the technical solution of the present application can reduce the computing task.

In addition, the IoV service terminal will only return response information to the IoV task terminal when it supports the information of the computing task. If it does not support it, it will not return a response message. Therefore, the number of response information is reduced, and the air interface signaling can be reduced. cost and improve the performance of the Internet of Vehicles.

In an optional solution, according to the m response messages and the m signal qualities, at least one Internet of Vehicles service terminal is selected from the m number of the Internet of Vehicles service terminals to establish a connection, and the execution of the calculation task is performed. Subsequent uninstall operations can include:

If the feedback information contained in the m response messages supports the information of the computing task contained in the discovery request message, the IoV task terminal selects the IoV service terminal with the best signal quality from the m IoV service terminals to establish a connection, and executes the a subsequent unloading operation of the computing task;

If the feedback information contained in the m response messages supports part of the computing task information contained in the discovery request message, the IoV task terminal selects n pieces of information that support part of the computing task information from the IoV service terminals that support part of the computing task type. The Internet of Vehicles service terminal establishes a connection, and performs subsequent unloading operations of computing tasks corresponding to some types. The above n is greater than or equal to 1 and less than or equal to m.

If the above-mentioned computing task types are multiple types, the above-mentioned partial types of supported computing tasks may specifically include: supporting one or more of the multiple types of computing tasks. For example, the computing task types are A and B. If the IoV service terminal supports A, the response message will carry the computing power requirements that support A and A.
