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 transfer of the above steps A16 and A17 can be performed by means of DNS Notify, HTTP 301 or HTTP 302. After the terminal device 21 obtains the target service location, it can connect to the service module that provides the target service in the second edge computing device 31 through the connection between the first edge computing device 11 and the second edge computing device 31 (step A18 and A19).

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. Next, the central control device 13 can be reconfigured. In this embodiment, the resource management module 135 generates a relocation request according to the abnormal condition of the service and transmits it to the service location management module 133 (step A22 ). Further, 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 .

As mentioned above, the service location management module 133 can record the service IDs of the services possessed by the edge computing devices 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 , using the one or more services as the target service, and then selecting The implementations of the candidate edge computing platform and the target edge computing platform are the same as those of the aforementioned embodiment in FIG. 4 , and will not be repeated here.
