In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

In order to facilitate understanding of the present application, technical terms related to technical solutions provided in the embodiments of the present application will be explained as follows:

Multi-Access Edge Computing (MEC): by migrating computing, storage and service capabilities to the edge of the network, localized, close-range and distributed deployment of content and services is achieved. An MEC (Cellular Vehicle-to-event, C-V2X) oriented to a mobile Internet of vehicles can provide a low-delay and high-performance network environment for Internet of vehicles services by using the characteristics of the MEC, and supports the deployment of C-V2X services with more local characteristics.

2. Road Side Unit (RSU): different operators deploy RSUs on the road side, so that on one hand, information can be collected, for example, a traffic management platform is connected to obtain road traffic flow information, traffic accident information and the like, and a road side sensor is connected to collect sensor information and the like; on the other hand, information can be forwarded, and the information is spread in a broadcast mode. Currently, in order to provide services to vehicles, an edge node needs to rely on RSUs to obtain necessary information in addition to uploading information of the vehicles.

3. MEC Orchestrator (MEC orchelator, MEO): the method can maintain the edge node topological graph, manage the application package, select the instantiation resource, authenticate and authenticate, and the like.

4. Edge Node (MEC Node, MEN): generally, the method is deployed in a network access layer or co-located with a base station, and different operators deploy applications in edge nodes, so that low-delay service can be provided for users.

5. Edge Management Node (MEC Management Node, MEMN): the upper node of the MEN stores a topology map of subordinate MEN, information collected by each subordinate MEN, information related to other operator edge management nodes, key information, and the like.

6. Application at edge node (MEC Application, MEA): and the edge nodes are deployed.

7. Edge computing Platform (MEC Platform, MEP).

8. An edge computing platform manager (MEPM).

In order to solve the problem that service interruption may occur when a service is provided based on single operator data at present, the application provides a multi-operator data sharing method based on an RSU, for example, when a certain operator edge node cannot acquire necessary data, data synchronization between different operators can be utilized to achieve the effect of providing the service based on the multi-operator data, thereby avoiding the phenomenon of service interruption and meeting the requirement of service continuity maintenance.

The data sharing method provided by the embodiment of the present invention is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1, fig. 1 is a flowchart of a data sharing method according to an embodiment of the present invention, where the method is applied to a first MEP of a first operator. As shown in fig. 1, the method comprises the steps of:

step 101: key information of the RSU of the second operator is obtained.

Understandably, the first operator is different from the second operator. The first operator and the second operator have made a contract, for example, when the first operator is agreed to fail to obtain necessary data, the RSU of the second operator provides the contract, and/or when the second operator is agreed to fail to obtain necessary data, the RSU of the first operator provides the contract.

Step 102: and sending the key information to a first terminal accessed to the first MEP.

In this embodiment, the key information is used for the first terminal to obtain data from the RSU of the second operator. The number of the first terminals may be one or more.

Step 103: and receiving target data reported by the first terminal.

In this embodiment, the target data is obtained by the first terminal from the RSU of the second operator according to the obtained key information.

In one embodiment, the first terminal may parse the broadcast message of the RSU of the second operator according to the key information to obtain specific content of the broadcast message, i.e. target data.

In one embodiment, the target data is, for example, traffic light information, road construction information, road fault information, and the like.

In the data sharing method of the embodiment of the present invention, the first MEP of the first operator may obtain the key information of the RSU of the second operator, send the key information to the first terminal accessing the first MEP, and receive the target data reported by the first terminal, where the target data is obtained by the first terminal from the RSU of the second operator according to the key information. Therefore, the first operator can acquire the data of the second operator, so that data synchronization among different operators is realized, the effect of providing services based on data of multiple operators can be achieved, the phenomenon of service interruption is avoided, and the requirement of service continuity maintenance is met.

In this embodiment of the present invention, the key information may be obtained by triggering the first MEPM of the first operator to initiate an authentication process. Optionally, the process of acquiring the key information of the RSU of the second operator may be:

the first MEP determines that data for providing services for the terminal are missing;

the first MEP sends data request information to a first MEPM of a first operator; the data request information is used for triggering the first MEPM to initiate an authentication process so that an MEO of a second operator performs authentication and certification on the data request information; the data request information comprises authentication information and the like related to the terminal;

the first MEP receiving the key information from the first MEPM; wherein the key information is obtained by the first MEPM from the MEO of the second operator based on the initiated authentication procedure.

It will be appreciated that the key information will only be sent to the first MEPM after the authentication of the MEO of the second operator has passed. This enables the first operator to obtain the required data from the second operator by means of an authentication procedure.

Further, the process of the first MEP determining that the data for providing the service for the terminal is missing may include:

the method comprises the steps that a first MEP determines first data required by providing service for a terminal and determines second data which can be acquired by the first MEP;

the first MEP comparing the first data and the second data;

and determining that the data for providing the service for the terminal is missing in the case that the second data does not include the first data, that is, the first MEP cannot acquire all data required for providing the service for the terminal.

It should be noted that, in order to trigger the first MEPM to initiate an authentication process, i.e. in order to determine that data for providing services for the terminal is missing, the newly added functions of the first MEPM include, but are not limited to: tracking a terminal such as a vehicle to obtain its location information, analyzing missing data against it, forming data request information, etc.

Optionally, when the number of the first terminals is multiple, each first terminal may report the target data to the first MEP. After receiving the target data from each first terminal, the first MEP may randomly select one target data reported by the first terminal from the received target data to store, and discard the target data reported by other first terminals. Therefore, by means of the data screening process, redundant data can be deleted, and the data effectiveness is improved.

Optionally, the first MEP may further receive historical data of synchronization of a second MEP of a second operator, so as to ensure integrity of the data and improve quality of subsequent services.

Optionally, after receiving the target data reported by the first terminal, the first MEP may provide a service by using a service delivery policy of at least one of the following:

providing services to terminals that cannot obtain services from the RSU of the second operator, and no longer providing services to terminals that can obtain services from the RSU of the second operator;

for the terminals which are subscribed to the services and include the services provided by the RSU of the second operator and are within the coverage range of the RSU of the second operator, the services provided by the RSU of the second operator are not provided any more;

and for the terminal which is in the coverage of the RSU of the second operator and the subscribed service comprises the service provided by the RSU of the second operator, when the terminal moves out of the coverage of the RSU of the second operator, the service is provided for the terminal.

The present application will be described in detail with reference to fig. 2 to 4.

Fig. 2 is a schematic view of an application scenario applicable to the present embodiment. A User Equipment (UE), such as a vehicle UE-a, signs up with an operator a and receives services provided by the operator a. Both operator A and operator B deploy edge computing platforms such as MEP-A and MEP-B in zone Z. Operator a cannot acquire necessary data in zone Z, and operator B can acquire data missing from operator a in zone Z. Operator a and operator B have contracted to be provided by the RSU of operator B when operator a cannot acquire the necessary data. The RSU of carrier B may support Uu port communications and PC5 communications. For some network elements related to the operator a and the operator B, see fig. 2, where PCF is a Policy Control Function (Policy Control Function), AUSF is an Authentication service Function (Authentication Server Function), UDM is Unified Data Management (Unified Data Management), AMF is an Access mobility Management Function (Access Management Function), and SMF is a Session Management Function (Session Management Function).

When the edge computing platform MEP-A of the operator A lacks datｃA in the region, an authentication process needs to be initiated, the edge computing orchestrator MEO-B of the operator B authenticates the datｃA, and after the authentication is passed, the edge computing platform MEP-A of the operator A obtains the key of the RSU-B and sends the key to the UE-A. After obtaining the key, the UE-A can analyze the broadcast information of the RSU-B to obtain the required datｃA and report the datｃA to the MEP-A. Meanwhile, the MEO-B can send a data request to the corresponding MEP-B based on the topological graph of the subordinate edge computing platform for synchronization of the historical data. The method specifically comprises four processes of authentication, key issuing, data synchronization and service provision.

(1) Authentication procedure

Before the edge computing platform MEP- ｃA of the operator ｃA obtains datｃA from the operator B, authentication of the operator B needs to be passed. The MEPM may send application related messages to the MEO, so in this scenario the authentication procedure is initiated by MEPM-a. The MEO has the function of authentication and authorization and simultaneously maintains the topological graph of the subordinate edge node, so that the MEO-B can authenticate the daA request of the MEPM-A and select ｃA subordinate edge computing platform MEP-B to synchronize the daA based on the position of the MEP-A.

Before the whole authentication process is started, authentication needs to be triggered, and the triggering process puts forward new functional requirements on the edge computing platform MEP-A, including vehicle tracking, comparative analysis of missing datｃA, formation of ｃA datｃA request message and sending of the datｃA request message to the MEPM-A and the like. The triggering process for discovering missing data and authentication flow may be as follows:

1) the MEP-A tracks the position change of the vehicle in real time;

2) comparing the position information of the vehicle with the range of the zone Z;

3) when the vehicle is detected to run to the area Z, inquiring an application list subscribed by the vehicle based on the ID of the vehicle, and further determining data required by application;

4) comparing datｃA required by application with datｃA which can be acquired by the current MEP-A;

5) determining missing datｃA when MEP-A provides service for UE through comparison;

6) and the MEP-A forms datｃA request information based on the missing datｃA, the authentication information related to the UE and the like, sends the datｃA request information to the MEPM-A and triggers the MEPM-A to initiate an authentication process.

As shown in fig. 3, the specific authentication procedure may include:

S1-S4: the authentication process is initiated by MEPM-A, reaches MEO-B through MEO-A, 5GC-A and 5GC-B, and needs to carry corresponding authentication information, application identification, daA request information and the like.

S5: and the MEO-B authenticates the request of the MEP-A based on the received authentication information, and selects the MEP-B at the subordinate edge node thereof as ｃA datｃA synchronization source based on the topological graph of the subordinate edge computing platform, the position information and the application information of the MEP-A and the like.

S6: and the MEO-B returns the authentication result and the key information of the RSU-B to the MEP-A along the original path.

S7-S8: and the MEO-B sends the authentication result and the datｃA synchronization request of the MEP-A to the MEP-B.

(2) Key distribution process

And after the MEP-A obtains the key information of the RSU-B, the key information is sent to the UE accessing the MEP-A. Because the vehicle connected with the MEP-A is always in ｃA moving state, the vehicle in the coverage range of the RSU-B is constantly changed. In order to ensure that the information of the RSU-B can be acquired, the MEP-A sends the key information of the RSU-B to all vehicles accessed in the areｃA.

(3) Data synchronization process

Alternatively, the data synchronization may include two parts, real-time data synchronization and historical data synchronization. As shown in fig. 4, a specific data synchronization process may include:

S1-S3: real-time data synchronization, RSU-B broadcasts messages such as signal lamp information, road construction information, road fault information and the like through PC 5; after receiving the broadcast information of the RSU-B, the UE-A analyzes the broadcast information according to the key information, and then specific content of the broadcast information can be obtained; and after analyzing the broadcast message, the UE-A sends the acquired information to the MEP-A, so that the MEP-A acquires the real-time information of the RUS broadcast.

S4-S6: and synchronizing the historical datｃA, and synchronizing the corresponding historical datｃA to the MEP-A by the MEP-B through the public network according to the datｃA request of the MEP-A.

S7: the MEP-A provides services based on the acquired datｃA.

Optionally, when performing real-time datｃA synchronization, the MEP- ｃA needs to have an information screening mechanism. That is, at the same time, when more than 1 UE- ｃA is in the RSU-B coverage, all UE- ｃA will upload the analyzed broadcast message to MEP- ｃA, resulting in information redundancy of MEP- ｃA. Thus, MEP- ｃA needs to establish an information screening algorithm:

i, receiving RSU-B information reported by ｃA plurality of UE-A by MEP-A, wherein the reported information carries ID (identity) of ｃA vehicle;

II MEP-A randomly selects one RSU-B message reported by UE-A from ｃA plurality of UE-A for storage, and discards the messages reported by other UE;

and III, the MEP-A tracks the UE according to the position information reported by the UE and the coverage areｃA information of the RSU-B, randomly selects ｃA message reported by another UE for analysis and storage when the UE is about to leave the coverage areｃA of the RSU-B, and repeats the II.

(4) Service provision

As shown in S7 in fig. 4, the MEP- ｃA receives the historical datｃA and the real-time datｃA, and provides ｃA service to the UE accessing the MEP- ｃA.

Optionally, after receiving the real-time information and the historical information, the MEP- ｃA needs to perform operations such as datｃA fusion, vehicle tracking, service delivery, and the like before providing the service. Further, MEP- ｃA needs to make ｃA service delivery policy for different services and terminals.

1) Data fusion: for receiving historical information provided by MEP-B, RSU-B information forwarded by UE-A and historical datｃA of MEP-A, MEP-A needs to fuse and remove redundancy of the information, and then service is provided based on the fused information.

2) Data fusion: for some services provided based on real-time messages, such as signal light information pushing, road construction reminding and the like, for vehicles within the coverage range of the RSU-B, the received RSU-B information is already provided with corresponding services. Therefore, MEP- ｃA needs to set ｃA service delivery policy:

a) classifying the services into services which can be obtained from the RSU-B and services which cannot be obtained from the RSU-B;

b) classifying the UE into vehicles in the RSU-B coverage range and vehicles not in the RSU-B coverage range;

c) when the subscribed services of the UE comprise services available by RSU-B and the UE is in the coverage range of the RSU-B, the MEP-A does not provide the services for the UE any more;

d) and the MEP-A tracks the UE mentioned in the step c in real time, and when the UE exits the coverage range of the RSU-B, the MEP-A restores providing various services for the UE.
