S101. Obtain a list of public land mobile networks (PLMNs) at the current location.

Specifically, when the user turns on or initiates, or the terminal detects that the registered PLMN has changed, the terminal is triggered to search for all frequency points supported by the user's current location, and obtain all available PLMN identities at the current location. These PLMN identities Said public land mobile network PLMN list is formed.

S102. Determine an eUICC remote management server address corresponding to each PLMN according to the mobile country code MCC of each PLMN in the PLMN list.

Specifically, the eUICC card itself stores the address of the eUICC remote management server in the area corresponding to each mobile country number MCC. Since the current location of the user is determined, the mobile country number MCC corresponding to each PLMN identifier in the PLMN list obtained in step S101 only one. The terminal obtains and stores the MCC from the PLMN list, and then reads the address of the eUICC remote management server in the area corresponding to the MCC from the eUICC. At the same time, after the terminal obtains the address, it can choose to store the address.

S103. Filter each configuration file stored in the eUICC according to the PLMN list, and obtain a list of available configuration files.

MSISDN), International Mobile Subscriber Identification Number (IMSI for short) or a combination thereof, but the present invention is not limited thereto.

S104. Send the list of available configuration files to the eUICC remote management server, so that the eUICC remote management server verifies the validity of each configuration file in the list of available configuration files to obtain a list of valid configuration files.

Specifically, after receiving the list of available configuration files, the eUICC remote management server sends each configuration file in the list of available configuration files to the respective corresponding operator network systems, and the operator network system queries the received configuration files to confirm whether the configuration file is valid. For example: query whether the configuration file is in arrears, whether the number is canceled, etc., if the configuration file has no arrears or cancellation, it is considered to be a valid configuration file. The operator's network system feeds back the query result to the eUICC remote management server, and the eUICC remote management server sends the obtained valid configuration file list to the terminal.

S105. Receive the valid configuration file list sent by the eUICC remote management server, and determine that the configuration files included in the valid configuration file list are standby configuration files.

Specifically, the terminal receives the valid configuration file list sent by the eUICC remote management server, and stores each valid configuration file in the list into the local backup configuration file list of the eUICC. If the current network is lost, the terminal selects a backup configuration file from the local backup configuration file list to access the network.

S203. Receive the temporary configuration file sent by the eUICC remote management server, and determine that the temporary configuration file is a standby configuration file.

Specifically, if the list of available configuration files is not empty, that is, the length of the list of available configuration files is greater than or equal to 1, that is, at least one of the configuration files stored in the eUICC supports the PLMN in the PLMN list, or , there is at least one available configuration file in the list of available configuration files, and then the list of available configuration files is sent to the eUICC remote management server, and the eUICC remote management server is an operator corresponding to each configuration file in the list of available configuration files The network system establishes a connection, and verifies the validity of each configuration file through the operator's network system to determine whether each configuration file can be used as a backup configuration file.

If the list of available configuration files is empty, that is, the length of the list of available configuration files is equal to 0, that is, none of the configuration files stored in the eUICC supports the PLMN in the PLMN list, in this case, send The eUICC remote management server sends an acquisition request, requesting the eUICC remote management server to assign a temporary configuration file to the terminal, and the terminal stores the temporary configuration file as a backup configuration file, and activates the temporary configuration file when the current network connection is lost file for network access.

In this embodiment, by logically judging the obtained list of available configuration files, when the list of available configuration files is not empty, each available configuration file in the list of available configuration files is sent to the eUICC remote management server, and the eUICC remote management server sends each The operator's network system of the configuration files verifies the validity of each configuration file, and then the eUICC remote management server returns the verified valid configuration files to the terminal, and the terminal takes the received valid configuration file as a backup configuration file. When the list of available configuration files is empty, it directly requests the eUICC remote management server to allocate a temporary configuration file, so that the user can quickly access the network again when the network is lost.

In this embodiment, step S104, sending the list of available configuration files to the eUICC remote management server, so that the eUICC remote management server can verify the validity of each configuration file in the list of available configuration files, and obtain After the list of valid configuration files, the method further includes:

S204. Determine whether the list of valid configuration files is empty, and if the list of valid configuration files is not empty, execute the step 105, and if the list of effective configuration files is empty, execute the step S202.

Specifically, when the available configuration files received by the eUICC remote management server are all unavailable after being verified by their corresponding operator network systems, for example, the configuration files are in arrears or downtime or canceled, that is, the list of valid configuration files is empty. In this case, the terminal sends an acquisition request to the eUICC remote management server, requesting the eUICC remote management server to allocate a temporary configuration file to the terminal, and the terminal stores the temporary configuration file and uses it as a backup configuration file. When the current network is connected, the temporary configuration file is activated to realize network access.

In this embodiment, by judging the obtained list of available configuration files and the list of valid configuration files, when there is no available configuration file in the eUICC, or when the available configuration file is verified as an invalid configuration file by the operator's network system, the eUICC is requested to remotely The management server pushes a temporary configuration file to the terminal as a backup configuration file. The temporary configuration file is used for when the currently activated configuration file of the terminal suddenly cannot be connected to the Internet due to reasons such as the terminal leaving the network coverage area or a network failure, etc., the user can activate the temporary configuration file first to provide a temporary network connection for the terminal.

S301. Determine whether a temporary configuration file is pre-stored in the eUICC. If there is no pre-stored temporary configuration file in the eUICC, perform step S103. If a temporary configuration file is pre-stored in the eUICC, perform step S302.

S302. Determine whether the address of the eUICC remote management server corresponding to the pre-stored temporary configuration file is consistent with the address of the eUICC remote management server, if the address of the eUICC remote management server corresponding to the pre-stored temporary configuration file is the same as the address of the eUICC remote management server If the addresses of the servers are consistent, step S303 is executed, and if the address of the eUICC remote management server corresponding to the prestored temporary configuration file is inconsistent with the address of the eUICC remote management server, step S304 is executed.

S303. Determine that the prestored temporary configuration file is a backup configuration file.

Specifically, when the address of the eUICC remote management server corresponding to the temporary configuration file stored in the terminal is consistent with the address of the eUICC remote management server, the terminal directly uses the pre-stored temporary configuration file as a backup configuration file. When the current network connection is lost, The network access can be performed directly by activating the pre-stored temporary configuration file, so that the terminal can quickly access the network.

S304. Delete the pre-stored temporary configuration file in the eUICC.

Specifically, if the terminal has stored a temporary configuration file locally, the terminal compares the address of the eUICC remote management server corresponding to the temporary configuration file with the address of the eUICC remote management server corresponding to the current location of the terminal. When the address of the eUICC remote management server is inconsistent with the address of the eUICC remote management server at the user's current location, it can be understood that the terminal has roamed from one area to the remote management server in another area, and the temporary configuration file previously stored on the terminal will be deleted , and notify the original eUICC remote management server corresponding to the pre-stored temporary configuration file through the eUICC remote management server corresponding to the user's current location, so that the original eUICC remote management server changes the state of the temporary configuration file.

In this embodiment, when a temporary configuration file is pre-stored locally in the terminal, if the server address corresponding to the pre-stored temporary configuration file is inconsistent with the server address corresponding to the user's current location, the terminal deletes the temporary configuration file and notifies the original eUICC through the current eUICC remote management server The remote management server changes the state of the pre-stored temporary configuration file. Since the server corresponding to the pre-stored temporary configuration file is not the remote management server corresponding to the user's current location, the pre-stored temporary configuration file is unavailable. In this embodiment, in order to prevent the pre-stored temporary configuration file from being related to the current eUICC remote management server The temporary configuration file pushed by the server to the terminal is confused, and the pre-stored temporary configuration file is deleted to ensure that all the pre-activated temporary configuration files selected by the terminal locally are available and guarantee the user's successful access to the network.
