In step 208, for each computer device 11 that receives a query reply from the server 13 via the communication unit 12, the computer device 11 obtains the corresponding type of the target application according to the query reply.

In step 209, for each file attribute of the target application program and the server-side file attribute in the server-side lookup table, there is no matching query request, the server 13 generates and transmits a through the communication network 100 The error message of the user terminal application related to the query request is sent to the computer device 11 corresponding to the query request.

In step 210, for each computer device 11 that receives an error message from the server 13 via the communication unit 12, the computer device 11 generates and displays a target application related to the error message according to the error message The input request of the program causes the user of the computer device 11 to directly input a type according to the input request to generate an input signal indicating the type corresponding to the target application.

In step 211, for each computer device 11 that receives the input signal, the computer device 11 obtains the type corresponding to the target application according to the input signal.

In step 212 after step 208 or step 211, for each computer device 11 of the type corresponding to the target application, the computer device 11 updates the user end lookup table according to the type obtained in step 208 or step 211 .

It should be particularly noted that in this embodiment, the file attributes stored in the user-side lookup table stored by each computer device 11 are less than the file attributes stored in the server-side lookup table stored by the server 13, each A user-side lookup table may only include file attributes of commonly used or used user-side applications, to reduce the storage space occupied by each user-side lookup table, and for each determination that the user-side lookup table does not exist The matching computer device 11, the query reply returned by the server 13 updates the user-side lookup table, and when the server determines that there is no match in the server-side lookup table, the user can further define the type.

In step 213, for each computer device 11, the computer device 11 generates and transmits a notification message including the corresponding type of the target application to the communication unit 12.

In step 214, for each computer device 11, after the communication unit 12 receives the notification message from the computer device 11, the communication unit 12 according to the type indicated by the notification message of the computer device 11 and the The communication terminal looks up the table to obtain the priority corresponding to the computer device 11.

In step 215, the communication unit 12 sequentially transmits the packets generated by the computer devices 11 to the corresponding target addresses according to the priorities corresponding to the computer devices 11.

In one embodiment, it is assumed that in the communication terminal lookup table of the communication unit 12, the priority corresponding to the game type is high, the priority corresponding to the media stream type is medium, and the priority corresponding to the file transmission type is low , There is a computer device 11 corresponding to the top layer of the target application type is media streaming, then after the communication unit 12 receives the notification message of the computer device 11, the computer device 11 has priority in the communication device , And when the computer device 11 opens an application of type game, making the application of type game the uppermost target application, after the communication unit 12 receives the latest notification message of the computer device 11, the computer The priority of the device 11 in the communication device is high.

It is worth noting that in this embodiment, step 213 is after step 212. In other embodiments, step 213 can also be performed before step 212, that is, step 211 is performed after step 204, step 208, or step 211 , Not limited to this.
