The second data transmission module, the SIM/UIM driving module and the APDU remote transmission service module are connected in sequence. The first data transmission module is connected with the second data transmission module and is used for data transmission between the first application processor and the first baseband processor.

Further, referring to fig. 5, a second embodiment of the eSIM card operating method of the present invention is proposed based on the above-described first embodiment, and is different from the foregoing embodiments in that the eSIM card operating method further includes:

step S30, detecting whether the eSIM card device is connected to the mobile terminal;

step S40, if it is detected that the eSIM card device is not connected to the mobile terminal and a connection request sent by the eSIM card device is received, determining a connection mode between the eSIM card device and the mobile terminal according to the connection request.

When the mobile terminal receives an eSIM card operating instruction through a user interface, the mobile terminal detects whether the eSIM card equipment is connected with the mobile terminal. And if the situation that the eSIM card equipment is not connected with the mobile terminal is detected, the mobile terminal detects whether a connection request sent by the eSIM card equipment is received or not. And after receiving the connection request sent by the eSIM card equipment, the mobile terminal extracts the connection identifier in the connection request and determines the connection mode according to the connection identifier. In this embodiment, there are two connection methods, one is a short distance connection method and the other is a long distance connection method. The remote connection mode is a connection through a server, and the Near connection mode is a connection through NFC (Near Field Communication), WiFi, bluetooth, and the like. The connection identifiers corresponding to different connection modes are different, so that the connection mode can be determined through the connection identifiers.

Step S50, if it is determined that the connection mode between the eSIM card device and the mobile terminal is the long-distance connection mode, establishing a connection between the eSIM card device and the mobile terminal according to the connection request.

And if the mobile terminal determines that the connection mode between the mobile terminal and the eSIM card equipment is a long-distance connection mode, the mobile terminal establishes connection with the eSIM card equipment through the server according to the connection request.

Further, the eSIM card operating method further includes:

and b, if the connection mode of the eSIM card equipment and the mobile terminal is determined to be a close-range connection mode, detecting whether the eSIM card equipment is in a connectable area of the mobile terminal.

If the mobile terminal determines that the connection mode between the mobile terminal and the eSIM card device is the close-range connection mode, the mobile terminal determines whether the eSIM card device is in the connectable area, wherein the connectable area can be divided into an NFC connectable area, a Bluetooth connectable area and a WiFi connectable area according to the connection mode between the eSIM card device and the mobile terminal. Specifically, the mobile terminal may determine whether the eSIM card device is within an NFC connectable area, and if the eSIM card device is not within the NFC connectable area, the mobile terminal may further determine whether the eSIM card device is within a bluetooth connectable area, that is, determine whether a bluetooth signal of the eSIM card device can be searched, if a bluetooth signal of the eSIM card device can be searched, the mobile terminal may determine that the eSIM card device is within the bluetooth connectable area, and if a bluetooth signal of the eSIM card device is not searched, the mobile terminal may determine that the eSIM card device is not within the bluetooth connectable area. If it is determined that the eSIM card device is not within the bluetooth connectable area, the mobile terminal may further determine whether the eSIM card device is within the WiFi connectable area. The ranges corresponding to the NFC connectable area, the bluetooth connectable area, and the WiFi connectable area are determined according to the attributes of various connection methods. It is to be understood that whether the eSIM card device is in the NFC connectable area, whether it is in the bluetooth connectable area, and whether it is in the WiFi connectable area may also be separately detected.

And c, if the eSIM card equipment is in the connectable area of the mobile terminal, establishing the connection between the eSIM card equipment and the mobile terminal according to the connection request.

In this embodiment, if the eSIM card device is within the connectable area of the mobile terminal, the mobile terminal establishes a connection with the eSIM card device according to the connection request. If the eSIM card equipment is not in the connectable area of the mobile terminal, namely the eSIM card equipment is not in the connectable area of NFC, the connectable area of Bluetooth and the connectable area of WiFi, the mobile terminal displays connection reminding information through a user interface so as to prompt that the eSIM card equipment and the mobile terminal of the corresponding user are failed to be connected.

Further, step c comprises:

and d, if the eSIM card equipment is in the connectable area of the mobile terminal, detecting whether the eSIM card equipment is paired with the mobile terminal.

And e, if the eSIM card equipment is paired with the mobile terminal, establishing the connection between the eSIM card equipment and the mobile terminal according to the connection request.

If it is determined that the eSIM card device is within a bluetooth connectable area of the mobile terminal, the mobile terminal detects whether the eSIM card device is paired therewith. When it is determined that the eSIM card device is paired with the mobile terminal, the mobile terminal establishes a connection with its eSIM card device according to the connection request.

Further, the eSIM card operating method further includes:

and f, if the eSIM card equipment is not paired with the mobile terminal, sending a pairing message to the eSIM card equipment so that the eSIM card equipment can be paired with the mobile terminal according to the pairing message.

And when the eSIM card equipment is determined to be unpaired with the mobile terminal, the mobile terminal outputs pairing reminding information through a user interface to remind a user of manually completing Bluetooth pairing of the eSIM card equipment and the mobile terminal, and then after the pairing is successful, the connection between the eSIM card equipment and the eSIM card equipment is established according to the connection request.

It is to be appreciated that when determining that the eSIM card device is connected to the mobile terminal in a long-range connection, the mobile terminal also needs to detect whether the eSIM card device has been paired therewith and then decide whether to establish a connection with the eSIM card device.

In this embodiment, before the transmission operation of the eSIM card operation instruction is performed, whether the mobile terminal is connected to the eSIM card device is detected, and the connection between the eSIM card device and the mobile terminal is automatically established according to the connection mode between the eSIM card device and the mobile terminal, so that the eSIM card operation instruction cannot be transmitted in time after the eSIM card operation instruction is triggered.
