The service failure signal corresponding to service suspension or removal may include the ID of the first edge computing device 11, the ID of the target service, and the ID of one or more terminal devices 21 connected to the abnormal edge computing platform.

When the service location management module 133 of the central control device 13 receives the service failure signal and learns that the first edge computing device 11 has a service abnormal condition, the service location management module 133 and the service redirection module 134 can reconfigure accordingly . In this embodiment, the reconfiguration includes a re-locate procedure and a re-direct procedure. The relocation process (step A12) may include: selecting an edge computing device that can provide the target service as a candidate edge computing platform, and determining the target edge computing platform based on the computing information of the candidate edge computing platform. As mentioned above, the central control device 13 can periodically collect information such as the resource status of one or more edge computing devices connected and the delay of the services provided. Furthermore, the service location management module 133 of the central control device 13 can obtain the target service ID from the service failure signal, select the edge computing device containing the service module with the target service ID as the candidate edge computing platform, and then select the edge computing platform with the best The edge computing device of the best computing information is used as the target edge computing platform, that is, the edge computing platform that is expected to continue to provide the target service to the terminal device 21.

The judgment of the optimal calculation information may have different standards according to the type of the target service. For example, for virtual reality services, the bandwidth resource status can be used as the main consideration, but this disclosure is not limited to this. In addition, the number of terminal devices 21 with target service needs is also one of the important considerations. The service location management module 133 can learn from the ID of the terminal device 21 contained in the service failure signal the number of terminal devices 21 with target service needs. To determine whether the resource status of the candidate edge computing platform is sufficient to provide the target service to the number of terminal devices 21.

In short, the first edge computing device 11 and the second edge computing device 31 can obtain redirection information and uninstall information from the central control device 13 respectively, and establish a connection with the other party about the terminal device 21 and the target service. In addition, when the second edge computing device 31 receives the uninstall information, it can obtain the location information (such as IP) of the corresponding service module as the target service location based on the target service ID in the uninstall information, and return a confirmation message to the service. The redirection module 134 indicates that the uninstallation information is successfully transmitted. In particular, the confirmation message corresponding to step A15 contains the target service location.

The service redirection module 134 of the central control device 13 further transmits the target service location to the terminal device 21 through the first edge computing device 11. Furthermore, the service redirection module 134 may wait for the second edge computing device 31 to return the confirmation message corresponding to step A15, obtain the target service location from the confirmation message, and send the ID of the terminal device 21 and the target service location to The first edge computing device 11 (step A16). The first edge computing device 11 obtains the target service location from the central control device 13, and can transmit the target service location to the terminal device 21 according to the ID of the terminal device 21 (step A17). In particular, the information transmission of the above steps A16 and A17 can be carried out by means of DNS Notify, HTTP 301 or HTTP 302. After the terminal device 21 obtains the target service location, it can then connect to the service module of the second edge computing device 31 that provides the target service through the connection between the first edge computing device 11 and the second edge computing device 31 (step A18 and A19).

In addition to the above-mentioned service abnormalities in response to service suspension or service removal, the network communication control method shown in Figure 3 can also respond to service abnormalities caused by platform failure.

In the embodiment shown in FIG. 5, the resource management module 135 of the central control device 13 can periodically obtain its information from the first edge computing device 11. When the resource management module 135 determines that the information from the first edge computing device 11 has not been received after a certain period of time (step A21), it can determine that the first edge computing device 11 is disabled. Then, the central control device 13 can be reconfigured. In this embodiment, the resource management module 135 generates a relocation request based on the abnormal service condition and transmits it to the service location management module 133 (step A22). Furthermore, the relocation request may include the ID of the first edge computing device 11 and the ID of the terminal device 21 originally connected to the first edge computing device 11.

The service location management module 133 executes a relocation process according to the relocation request to generate a relocation response and send it back to the resource management module 135 (step A23). As mentioned above, the service location management module 133 can record the service ID of each service possessed by the edge computing device connected to the central control device 13. Therefore, the relocation procedure may include obtaining one or more services originally possessed by the first edge computing device 11 according to the ID of the first edge computing device 11, and using the one or more services as target services, and subsequently selecting The implementation manners of the candidate edge computing platform and the target edge computing platform are the same as those of the embodiment in FIG. 4, and will not be repeated here. The relocation response generated by the service location management module 133 may include the ID of the target edge computing platform, the target service ID, and the ID of the terminal device 21. In the embodiment of FIG. 3, the second edge computing device 31 is selected as the target edge computing platform by the service location management module 133. Therefore, in this embodiment, the relocation response will include the second edge computing device 31 ID.

The central control device 13 reconfigures the target service to the second edge computing device 31 through the above procedure, and generates uninstall information and target service location, and then respectively transmits the uninstall information to the second edge computing device 31, and sends the target service location to the terminal装置21。 Device 21. Furthermore, the resource management module 135 of the central control device 13 generates uninstall information including the ID of the terminal device 21 and the target service ID according to the relocation response and transmits the uninstall information to the second edge computing device 31 (step A24). In this way, the second edge computing device 31 can know that the target service will be provided to the terminal device 21 in the future based on the uninstall information, and when the second edge computing device 31 receives the uninstall information, it can be based on the target service ID in the uninstall information. Obtain the location information (for example, IP) of the corresponding service module as the target service location, and return a confirmation message to the resource management module 135 to indicate that the uninstallation information is successfully delivered. In particular, this confirmation message contains the target service location.

The resource management module 135 of the central control device 13 further transmits the target service location to the terminal device 21 through the second edge computing device 31. Furthermore, the resource management module 135 may wait for the second edge computing device 31 to return a confirmation message, obtain the target service location from the confirmation message, and send the ID of the terminal device 21 and the target service location to the second edge computing device 31 (Step A25). The second edge computing device 31 obtains the target service location from the central control device 13, and can transmit the target service location to the terminal device 21 according to the ID of the terminal device 21 (step A26). In particular, the information transmission of the above steps A25 and A26 can be performed through DNS Notify, HTTP 301 or HTTP 302. After the terminal device 21 obtains the target service location, it can accordingly connect to the service module that provides the target service in the second edge computing device 31 (step A27). In particular, in this embodiment, before performing the edge computing platform conversion, the terminal device 21 is connected to the first edge computing device 11 and the second edge computing device 31 at the same time. In detail, the base station to which the terminal device 21 is connected is originally connected to the first edge computing device 11 and the second edge computing device 31 respectively.
