The descriptions of the first, second, etc. appearing in the embodiments of the present application are only for illustrating and differentiating the objects, and do not represent the order or the particular limitation of the number of the devices in the embodiments of the present application, and do not constitute any limitation to the embodiments of the present application. The term "connect" in the embodiments of the present application refers to various connection manners, such as direct connection or indirect connection, to implement communication between devices, which is not limited in this embodiment of the present application.
The technical solution of the embodiment of the present application may be applied to the example communication system 100 shown in fig. 1A, where the example communication system 100 includes a terminal 110 and a network device 120, and the terminal 110 is communicatively connected to the network device 120.
The example communication system 100 may be, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an Advanced Long Term Evolution (LTE-a) System, a New Radio (NR) System, an Evolution System of an NR System, an LTE-over-unlicensed spectrum (LTE-U) System, an NR-over-unlicensed spectrum (NR-over-licensed spectrum) System, a Universal Mobile Telecommunications System (UMTS) System, or other next generation communication systems.
Generally, conventional Communication systems support a limited number of connections and are easy to implement, however, with the development of Communication technology, mobile Communication systems will support not only conventional Communication, but also, for example, Device-to-Device (D2D) Communication, Machine-to-Machine (M2M) Communication, Machine Type Communication (MTC), and Vehicle-to-Vehicle (V2V) Communication, and the embodiments of the present application can also be applied to these Communication systems. Optionally, the communication system in the embodiment of the present application may be applied to a Carrier Aggregation (CA) scenario, may also be applied to a Dual Connectivity (DC) scenario, and may also be applied to an independent (SA) networking scenario.
A terminal 110 in the embodiments of the present application may refer to a user equipment, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user device. The terminal may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a relay device, a vehicle-mounted device, a wearable device, a terminal in a future 5G network or a terminal in a future evolved Public Land Mobile Network (PLMN), and the like, which are not limited in this embodiment.

However, in the process of offloading the computing task, if the car networking task terminal initiating offloading the computing task does not know information such as computing power conditions and loads supported by surrounding terminals, it is impossible to select a suitable node or a node list for offloading the computing task. One possible method is to send the calculation task to all surrounding car networking terminals, but this approach has low effective calculation resource utilization rate, and affects air interface resource utilization rate of the car networking terminals and other services running on the car networking service terminals (car networking terminals that provide calculation assistance service for the car networking task terminals, i.e., car networking service terminals).

The information of the computing task comprises one or any combination of the following:
calculating a type list of tasks and calculating power requirements of the tasks;
the list of types of computing tasks includes: a single calculation task type list and a plurality of calculation task type lists;
the computing power requirement of the computing task comprises one or any combination of the following: calculating peak rate and capacity;

and m is an integer greater than or equal to 1.
The specific implementation method of the step S204 may include: the signal quality between the task V2X terminal (corresponding to the car networking task terminal) and the service V2X terminal (corresponding to the car networking service terminal) establishing the connection is to satisfy a threshold condition: when only one service V2X terminal is selected for task unloading, selecting the service V2X terminal which meets the calculation requirement and has the best signal quality to establish connection; when a plurality of service V2X terminals are selected, if the unloading task amount to each service V2X terminal is the same, the service V2X terminal is selected according to the signal quality priority; if the amount of tasks to be offloaded to each service V2X terminal is different, the service V2X terminal may be selected in consideration of available computational power support and signal quality, and the present application does not limit the specific representation form of selecting the service V2X terminal.
The implementation method of the step S204 may specifically include:
under a single computing task requirement:
if a single service V2X terminal can meet the demand of computational resources, the task V2X terminal mainly selects from candidate service V2X terminals according to channel quality, and in combination with the technical scenarios of the first and second embodiments, i.e., UE-5 which does not meet the demand of computational power is first excluded from candidate UEs-2, UE-3, UE-4, UE-5 and UE-7, then UE-4 with poor signal quality is excluded from candidate UEs-2, UE-3, UE-4 and UE-7, and then the connection with the best signal quality is selected for establishment, and the evaluation manner of signal quality may be in the form of RSRP, RSRQ, etc., so that UE-1 may select UE-2 or UE-7 to establish PC5 connection, and then initiate subsequent operations such as task offloading.
If the single service V2X terminal does not satisfy the computing resource requirement, the task V2X terminal selects among the candidate service V2X terminals according to the channel quality and the available computing resources, for example, the computing resource requirement of the UE-1 to the computing task a is a0+ a1+ 2a 2, then the UE-1 selects to establish a PC5 connection with the UE-2, UE-3, UE-5 and UE-7 according to the available computing resources fed back in the response messages of the UE-2, UE-3, UE-4, UE-5 and UE-7, in combination with the signal quality of these candidate service V2X terminals, and then initiates the subsequent task offloading operation.
Under the demand of multiple computing tasks:
if a single service V2X terminal can simultaneously meet the requirement of multitask calculation, the task V2X terminal mainly selects from candidate service V2X terminals according to the channel quality;
if a single service V2X terminal cannot satisfy the multi-task computing requirement at the same time, the method may refer to the implementation method that if a single service V2X terminal does not satisfy the computing resource requirement under the single-task computing requirement, process each computing task separately, select a suitable service V2X terminal to establish connection, and then perform the subsequent operation of task offloading.
In the method shown in fig. 2, the combination of steps S201, S203 and S204 may be an implementation method on the task terminal side of the internet of vehicles, and step S202 may be a support method on the service terminal side of the internet of vehicles.

if the feedback information contained in the m response messages supports the information of the calculation task contained in the discovery request message, the vehicle networking task terminal selects one vehicle networking service terminal with the best signal quality from the m vehicle networking service terminals to establish connection, and executes the subsequent unloading operation of the calculation task;
if the feedback information contained in the m response messages supports part discovery of the information of the calculation tasks contained in the request message, the vehicle networking task terminal selects n vehicle networking service terminals supporting part calculation task information from the vehicle networking service terminals supporting part calculation task types to establish connection, and executes subsequent unloading operation of the calculation tasks corresponding to the part types, wherein n is greater than or equal to 1 and less than or equal to m.
If the computing task type is a plurality of types, the supporting of the computing task part type may specifically include: one or several of a plurality of types of computational tasks are supported. For example, the type of the calculation task is A, B, and if the car networking service terminal supports a, the calculation capability requirement of the support a and a is carried in the response message.
