[0002] In the related art, wireless communication systems provide basic connection capabilities anytime and anywhere for the Internet of Everything. With the gradual application of wireless technology among vehicles, vehicle-road, vehicle-person, and vehicle-cloud, the Internet of Vehicles will greatly enhance driving safety, improve traffic efficiency, save energy and reduce emissions, and promote green and shared urban travel.

[0003] When the connection services provided by wireless communication systems gradually become the basic support for Internet of Vehicles applications, being able to effectively and accurately provide connection service prediction is becoming increasingly crucial for Internet of Vehicles applications, and even becomes a key ability for the Internet of Vehicles to be recognized by the industry. Through connection service prediction, Internet of Vehicles applications (such as autonomous driving, intelligent transportation systems) can obtain in advance the capabilities that the communication connection in a certain geographical area can achieve in a future period of time, as well as the changes in these capabilities, which will help these Internet of Vehicles applications calculate and adjust their working modes in advance to ensure driving safety or business availability.

[0004] However, predicting connection services requires consuming various resources such as connection, storage, and computing of wireless communication systems. The more content needs to be predicted, the higher the accuracy, the greater the lead time, and the larger the coverage area, the more resources for connection, storage, and computing are required. Moreover, the types of predictions, accuracy, regions, prediction refresh frequencies, prediction lead times, etc. required by different Internet of Vehicles applications are not the same.

[0022] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence.

[0024] In the related art, the 3GPP TR23.786 of the third-generation mobile communication technology discusses a scheme for path-based quality of service (QoS) resource reservation to ensure that the network can provide the required connection service quality for vehicle-to-everything (V2X) applications on a certain path within a future time window. This method mainly judges whether resource reservation can be made based on the connection service quality requirements given by V2X applications and the planned path, as well as the future time window, so as to give a response on whether to support the connection quality service requirements and the corresponding credibility. However, in fact, the connection service quality requirements given by in-vehicle terminals may change continuously. If the wireless communication system can provide more accurate and detailed connection service quality prediction information, rather than just "supportable" or "not supportable", then V2X applications can use this information to adjust relevant perception algorithms, autonomous driving algorithms, etc.

[0025] 3GPP TR23.786 further discusses a potential QoS change notification scheme. V2X applications can require the wireless communication system to notify V2X applications when the connection service quality changes, so that V2X applications can make adjustments. This method mainly notifies V2X applications when the wireless communication system detects that the connection service quality has changed according to the requirements of V2X applications. This scheme mainly provides the connection service quality changes that have occurred and cannot provide predictions for future network connections. Moreover, it provides a unified notification to V2X applications and cannot provide customized information.

[0069] A method for effectively providing connection service quality prediction information of a wireless communication system according to the present application includes the following content:

[0070] The connection service quality prediction function can be supported by a single network element or by multiple network elements in cooperation; it can either belong to the wireless communication system or cooperate with the wireless communication system to implement the connection service quality prediction function. An interface is established between the wireless communication system and the vehicle networking application to interact relevant connection service quality prediction requirements and connection service quality prediction reports.

[0076] One or more connection service indicators required to be reported in the above-mentioned target area include delay, reliability, availability, throughput, coverage, capacity, etc.

[0077] The above-mentioned credibility of the provided connection service quality prediction can be the confidence interval for each connection service indicator or the overall confidence interval of the connection service quality prediction information.

[0078] The above-mentioned accuracy of the prediction information refers to the accuracy of the numerical value of each connection service quality indicator required to be reported.

[0080] The IoV application sends a connection service quality prediction information configuration message, carrying at least the corresponding application ID and one or more of the above parameters to the wireless communication system.

[0081] The IoV application can also call the API provided by the wireless communication system to configure the connection service quality prediction parameters.

[0082] After receiving this information, the wireless communication system determines whether the predicted configuration requirements for the connection service quality can be accepted according to relevant policies.

[0083] -- If accepted, it replies acceptance to the vehicle networking application.

[0087] When partially accepted, the content of the predicted configuration parameters for the connection service quality that can be supported can be pre - configured or dynamically requested from the policy server of the wireless communication system.

[0092] When the wireless communication system starts up, there can be one or several sets of pre - configured predicted parameters for the connection service quality. Different vehicle networking applications can select one set of predicted parameters for the connection service quality by calling an API interface.

[0093] The process of predicting the connection service quality can be started by a certain vehicle networking application through a start message for predicting the connection service quality.

[0094] The process of predicting the connection service quality can also be automatically started according to the start conditions set in the predicted parameters for the connection service quality configured by a certain vehicle networking application.

[0095] The connection service quality prediction process can also be initiated by a certain vehicle networking application through the API call interface.

[0096] If there are no connection service quality prediction parameters corresponding to the vehicle networking application at startup, the wireless communication system needs to request the connection service quality prediction parameters from the vehicle networking application that initiated this function, or require the vehicle networking application to select a set from the pre-configured parameters. This process can be either in the form of a message request or through the API interface.

[0097] The startup and configuration of parameters can be carried out continuously or independently.

[0098] After the connection service quality prediction function is started, the wireless communication system processes and reports data collection according to the negotiated connection service quality prediction parameters; the wireless communication system can transmit relevant prediction information to the vehicle networking application through the connection service quality prediction report, or feedback relevant prediction information through the API interface.

[0106] Connection service quality prediction function

[0107] A wireless communication system that supports the connection service quality prediction function, and this connection service quality prediction function can either be fully implemented by the wireless communication system; or it can be an independent function that collaborates with the wireless communication system to complete relevant prediction functions.

[0108] Various vehicle networking application systems.

[0109] If the connection service quality prediction function is independent of the wireless communication system, there is an information interaction interface between the connection service quality prediction function and the wireless communication system, which is used to transmit various configuration parameters and prediction report information.

[0110] There is an information interaction interface between the wireless communication system and the vehicle networking application. Through this interface, various vehicle networking application systems can independently interact with the wireless communication system respectively to configure, modify the connection service quality prediction parameters, start and terminate the connection service quality prediction function; and the wireless communication system provides connection service quality prediction information to different vehicle networking applications on demand. For the specific method, refer to the description of the above technical solution.

[0111] Figure 3 It is a schematic diagram of the interaction between the wireless communication system according to the embodiment of the present application and various vehicle networking applications Figure 1 , the wireless communication system includes a policy server and a connection service quality prediction function, and performs prediction parameter configuration / negotiation / reporting with vehicle networking applications A, B, X, etc., where the connection service quality prediction function is implemented by the wireless communication system. Through the interface between the wireless communication system and the vehicle networking application, the connection service quality prediction parameters are configured and modified, the connection service quality prediction function is started and terminated, and the wireless communication system provides connection service quality prediction information to the vehicle networking application on demand. As Figure 3 shown, the connection service quality prediction function can belong to the wireless communication system. An interface is established between the wireless communication system and the vehicle networking application to interact relevant connection service quality prediction requirements and connection service quality prediction reports.

[0112] Figure 4 It is a schematic diagram of the interaction between the wireless communication system according to the embodiment of the present application and various vehicle networking applications Figure 2, a wireless communication system includes a policy server, where the connection quality of service prediction function collaborates with the wireless communication system to complete functions such as relevant data collection, prediction processing, and prediction information reporting. Through the interface between the wireless communication system and the vehicle networking application, the connection quality of service prediction parameters are configured, modified, the connection quality of service prediction function is started and terminated, and the wireless communication system provides the connection quality of service prediction information to the vehicle networking application on demand. As Figure 4 shown, the connection quality of service prediction function may not belong to the wireless communication system. An interface is established between it and the wireless communication system to interact relevant data collection and prediction processing results. An interface is established between the wireless communication system and the vehicle networking application to interact relevant connection quality of service prediction requirements and connection quality of service prediction reports.

[0113] Figure 5 is a connection quality of service prediction configuration flow chart according to an embodiment of the present application. Different vehicle networking applications independently configure connection quality of service prediction information by sending connection quality of service prediction configurations according to service requirements. After receiving this information, the wireless communication system determines whether the connection quality of service prediction configuration requirements can be accepted according to relevant policies and sends a connection quality of service prediction information configuration response, which includes the following situations:

[0114] -- If the wireless communication system accepts, it replies acceptance to the vehicle networking application.

[0115] -- If the wireless communication system does not accept, it replies non - support to the vehicle networking application.

[0116] -- If the wireless communication system partially accepts, the wireless communication system needs to reply to the vehicle networking application with the content of the connection quality of service prediction configuration parameters that can be supported, that is, the adjusted configuration parameters.

[0117] At this time, the vehicle networking application receives the response content and judges whether it indicates that the wireless communication system partially accepts. If not, the configuration ends; if so, it feeds back a connection quality of service prediction information configuration response to the wireless communication system, which indicates whether the vehicle networking application accepts the adjusted configuration parameters, that is, if the vehicle networking application can accept the adjusted connection quality of service prediction configuration, it replies acceptance to the wireless communication network. If the vehicle networking application cannot accept, it notifies the wireless communication system that the connection quality of service prediction parameter negotiation is invalid.

[0118] Figure 6 is a flow chart for the vehicle networking application to start the connection quality of service prediction according to an embodiment of the present application, as Figure 6As shown, the vehicle networking application sends a connection service quality prediction start message. The wireless communication system checks if there are corresponding prediction parameters. If so, the start is completed. If not, the wireless communication system needs to request the connection service quality prediction parameters from the vehicle networking application that initiated this function, or ask the vehicle networking application to select a set from the pre-configured parameters. Subsequently, the wireless communication system receives the connection service quality prediction information configuration information sent by the vehicle networking application. This process can be requested either by message or through an API interface.

[0119] Figure 7 It is a flowchart for terminating the connection service quality prediction according to an embodiment of the present application. The connection service quality prediction process can be terminated as needed by the corresponding vehicle networking application or by the wireless communication system. That is, the vehicle networking application can send a connection service quality prediction termination message to the wireless communication system to terminate the prediction process, or the wireless communication system can initiate a connection service quality prediction termination message to terminate the prediction process.

[0120] According to the service requirements and the contract with the wireless communication system, vehicle networking application A sends a configuration request to the wireless communication system through a connection service quality prediction configuration message. The parameters to be configured are: the start and end times for prediction (e.g., 4 pm - 6 pm); the planned path for prediction (latitude and longitude of multiple landmarks on the highway); a 10-minute advance for prediction reporting time; the connection service quality prediction metrics to be predicted are delay, packet loss rate, and data throughput; the credibility requirement is accurate to 4 decimal places; the reporting frequency of the prediction information is 20 Hz.

[0121] According to the service requirements and the contract with the wireless communication system, vehicle networking application B calls the API provided by the wireless communication system to configure the connection service quality prediction information. The configured parameters are: the start and end times for prediction (4 pm - 6 pm today, Beijing time); the planned path for prediction (a 5-km diameter area centered on location L1); a 1-minute advance for prediction reporting time; a 100-m advance for prediction reporting distance; the connection service quality prediction metrics to be predicted are data throughput and packet loss rate; the credibility requirement is accurate to 3 decimal places; the reporting frequency of the prediction information is 1 Hz.

[0122] The vehicle networking application C calls the API provided by the wireless communication system to configure the connection service quality prediction information. The API provides the following configurable parameters: the start and end time for prediction (4 pm to 6 pm today, Beijing time); the planned path to be predicted (latitude and longitude of the regional center, regional radius); the prediction reporting time advance xx, in minutes or seconds; according to the contract between the application and the wireless communication system, the predictable connection service quality indicators available for this application are: data throughput and packet loss rate; the credibility requirement is accurate to 3 decimal places; the reporting frequency of the prediction information is 1 Hz.

[0123] After the wireless communication system receives the prediction parameter configuration information sent by three vehicle networking applications, it determines whether the connection service quality prediction configuration requirements can be accepted according to relevant policies.

[0124] -- If accepted, it replies "accepted" to this vehicle networking application.

[0125] -- If not accepted, it replies "not supported" to the vehicle networking application.

[0126] -- If partially accepted, the wireless communication system needs to reply to the vehicle networking application with the content of the connection service quality prediction configuration parameters that can be supported. At this time, if the vehicle networking application can accept the adjusted connection service quality prediction configuration, it replies "accepted" to the wireless communication network. If the vehicle networking application cannot accept it, it notifies the wireless communication system that the negotiation of the connection service quality prediction parameters is invalid.

[0127] The above-mentioned relevant policies can be pre-configured or dynamically requested from the policy server of the wireless communication system.

[0128] When partially accepted, the content of the connection service quality prediction configuration parameters that can be supported can be pre-configured or dynamically requested from the policy server of the wireless communication system.

[0129] The wireless communication system replies to the vehicle networking application A through the connection service quality prediction parameter configuration response message. The information carried in this response message is "accepted".

[0130] The wireless communication system replies to the vehicle networking application B by calling the API interface. The information carried in this response message is "not accepted" and the relevant reasons are carried. After that, the wireless communication system and the vehicle networking application B can restart the prediction parameter configuration process.

[0131] The wireless communication system replies to the vehicle networking application C by calling the API interface. The information carried in this response message is "partially accepted" and the adjusted connection service quality prediction configuration parameters. After receiving the adjusted connection service quality prediction configuration parameters, the vehicle networking application C calls the API interface to reply to accept the adjusted prediction configuration parameters.

[0132] The vehicle-to-everything (V2X) application A sends a connection service quality prediction start message to the wireless communication system.

[0133] The connection service quality prediction process corresponding to the V2X application C is automatically started according to the prediction configuration parameters.

[0134] The V2X application B starts the prediction process through the API call interface. At this time, if the V2X application B does not have the connection service quality prediction parameters corresponding to this V2X application, the wireless communication system needs to request the connection service quality prediction parameters from the V2X application B, or require this V2X application to select a set from the pre-configured parameters.

[0135] The start and configuration parameters can be carried out continuously or independently.

[0136] After the connection service quality prediction function is started, the wireless communication system processes and reports the data collection according to the negotiated connection service quality prediction parameters;

[0137] The wireless communication system transmits the connection service quality prediction information to the V2X application A 50 times per second through the connection service quality prediction report: application ID, time stamp, predicted connection service quality indicators (delay, packet loss rate, data throughput; the confidence level is accurate to 4 decimal places), highway longitude and latitude, predicted applicable time interval, and the base station location corresponding to the prediction information.

[0138] The wireless communication system feeds back the relevant prediction information to the V2X application B once per second through the API interface: application ID, time stamp, predicted connection service quality indicators (data throughput and packet loss rate; the confidence level is accurate to 2 decimal places), predicted applicable time interval, and the base station location corresponding to the prediction information.

[0139] The wireless communication system feeds back the relevant prediction information to the V2X application C through the API interface: application ID, time stamp, predicted connection service quality indicators (data throughput and packet loss rate; the confidence level is accurate to 3 decimal places), predicted applicable time interval, the central location of the predicted applicable geographical area, and the base station location corresponding to the prediction information.

[0140] The connection service quality prediction process can be terminated by the corresponding V2X application according to the need, or can be terminated by the wireless communication system.

[0141] The wireless communication system sends a connection service quality prediction termination message to the V2X application A, and the termination message carries the corresponding application ID and termination reason.

[0142] The V2X application B calls the API to terminate the connection service quality prediction process, carrying information such as the termination reason.

[0143] The connection service quality prediction process corresponding to the Internet of Vehicles application C is automatically terminated according to the termination condition (such as time termination) set in the connection service quality prediction parameters configured in the Internet of Vehicles application.

[0144] During the execution of the connection service quality prediction process, when the Internet of Vehicles application B needs to modify the connection service quality prediction parameters, it first terminates the existing connection service quality prediction process and then starts to configure new wireless communication connection service quality prediction information.

[0145] The Internet of Vehicles application B can also determine the effective start time when configuring new wireless communication connection service quality prediction information. When the time arrives, the existing prediction process is terminated and the prediction process is started according to the newly configured wireless communication connection service quality parameters.

[0146] Compared with related technologies, the above scheme can configure the connection service quality prediction parameters required for different Internet of Vehicles applications, so as to optimize the connection service quality prediction content according to the needs of different applications; the method described in this application supports the start of the prediction function, the setting of the prediction content, the definition of the prediction reporting mechanism, the prediction termination, the modification of the prediction parameters, etc. It can effectively reduce the consumption of communication, storage, and computing resources required by the wireless communication system in the process of connection service quality prediction, customize on demand, and effectively use resources to provide targeted services for Internet of Vehicles applications.
