In step S104, the card writing apparatus transmits a request to the server.
In some embodiments, the server may be, for example, an operator server. The request may include the purpose of the request, such as requesting to obtain a number, requesting to apply for a package, requesting a service change, etc.; in addition, a logo of the embedded smart card may be included.

Therefore, the terminal does not need to directly interact with the server, the hardware requirement on the terminal is reduced, and the application range of the eSIM card writing is improved.
In some embodiments, the communication module of the terminal has limited communication. In order to improve the reliability of communication, when the terminal communicates with the card writing device, the data can be unpacked. An embodiment of the card writing method of the present invention is described below with reference to fig. 2.
FIG. 2 is a flow chart illustrating a card writing method according to further embodiments of the present invention. As shown in fig. 2, the card writing method of this embodiment includes steps S202 to S218.
In step S202, the terminal splits the uplink data including the request information from the embedded smart card into uplink data packet groups.
In step S204, the terminal sends the uplink packet group to the card writing device through wireless communication. Each packet in the packet group may be transmitted in turn.

In step S212, the card writing device splits the downlink data into downlink packet groups.
In step S214, the card writing device sends the downlink data packet group to the terminal through wireless communication. Each packet in the packet group may be transmitted in turn.
In step S216, the terminal reassembles the downlink data packet group to obtain downlink data including response information.
In step S218, the terminal writes the content in the response message into the embedded smart card.
By the method of the embodiment, when the terminal and the card writing device perform data interaction, the data can be split into a plurality of data packets for transmission. Therefore, the success rate of data transmission can be improved, and the efficiency of data transmission is improved on the whole.
In some embodiments, the terminal and the card writing device can communicate with each other in a bluetooth mode. For example, the terminal and the card writing device may have BLE (Bluetooth Low Energy) chips, respectively. BLE chip has low-cost, short distance, interoperable's characteristics, and most equipment that carry the eSIM card such as intelligent wrist-watch, vehicle-mounted terminal, tracker all possess the BLE chip. Thus, some embodiments of the present invention may complete the function of over-the-air number writing through the BLE chip.
The BLE chip has a mechanism for unpacking the packets. Uplink data sent by the terminal can be unpacked by a BLE chip of the terminal and packaged by a BLE chip of the card writing device, and downlink data forwarded by the card writing device can be unpacked by the BLE chip of the card writing device and packaged by the BLE chip of the terminal. The BLE chip may, for example, split data into packets of less than or equal to 20 bytes. The mechanism of unpacking by the BLE chip is exemplarily described below.
In BLE technology, profile is a specification including a plurality of services, each of which represents a capability of a device; each service may in turn comprise a plurality of charactertics by which communication between BLE-based devices is achieved. In the profile related to the present invention, a service may be set, and the schematic composition of the service may be as shown in table 1.
TABLE 1
At the transmission level, data transmitted once by one characteristic may be defined as one frame, and the data length of each frame is, for example, 20 bytes. Payload refers to the data transported by this frame. In the communication layer, the payload is raw data (raw data), and has no fixed format, and the format and the semantics can be resolved by the service layer. Payload is 16 bytes long, and if less than 16 bytes, it can be filled with 0x 00. A frame of data may consist of a protocol frame header (frame _ hdr _ t) and payload. The Frame _ hdr _ t is composed of 4 bytes, and its code structure representation can be as follows, where the part behind the "//" symbol is the annotation content.
It is assumed that the terminal intends to send 1000 bytes of data to the card writing device, and the 1000 bytes of data are defined as 1 Packet (Packet). For example, after removing the protocol overhead of the header, if there are 16 bytes in the payload portion for transmitting data, 1000 bytes of data need to be transmitted in multiple times. In the case of transmitting 16 bytes of data per frame, after dividing 1000 bytes into 62 frames, the remaining 8 bytes are less than one frame, so the remaining 8 bytes need to be given a value of 0 to complete, and the data is divided into 63 frames, that is, a packet group including 63 packets is formed. The terminal sends the content of the first frame to the card-writing device through indication characteristics. When the terminal receives the confirm, it considers that the card writing device has read the data, and thus completes the transmission process of the first frame. Next, the terminal may sequentially transmit the remaining frames according to the step of transmitting the first frame. The original packet of data may form a structure of seq (serial number) + operation) + length) + content) + crc (check code), for example. And the terminal puts the data subjected to the framing operation on a BLE channel and sends the data. The data structure before framing can refer to table 2.
TABLE 2
| seq | operate | length | content | crc |
| 1byte | 1byte | 2byte | nbyte | 2byte |
The seq field is used for carrying out deduplication processing during overtime retransmission, the overtime threshold value can be preset, and the seq of the response packet needs to be consistent with the seq of the request packet; the crc field is used for checking and is a numerical value calculated according to the seq + operation + length + content field; the contents are data contents organized in a data format of TLV (TAG, Length, Value, label, Length, Value), and one content may include one or more TAG contents.
Accordingly, the card writing device receives data in a frame combining mode. When the card-writing terminal receives data through a write feature, the data reception process is started until all frames of a packet of data are completely received. Then, the card writing terminal restores the data of the packet by combining frames and then returns the data of the packet to the application layer.
In some embodiments, the data sent by the card writing device to the server is data processed by an LPA (Local profile assistant) component. The LPA components may be located on the card writing device or on the terminal. These two embodiments are exemplarily described below with reference to fig. 3A and 3B, respectively.
Fig. 3A is a flow chart illustrating a card writing method according to further embodiments of the present invention. In this embodiment, the LPA assembly is located on the terminal. As shown in FIG. 3A, the card writing method of the embodiment includes steps S3002-3014.
In step S3002, the terminal encapsulates the upstream LPA data from the embedded smart card by using the LPA component, and sends the encapsulated upstream LPA data to a BLE module of the terminal.
In step S3004, the terminal sends the encapsulated upstream LPA data to a BLE module of the card writing device through the BLE module.
In step S3006, the card writing device forwards the upstream LPA data to the server.
In step S3008, the card writing device receives downstream LPA data from the server.
In step S3010, the card writing device transmits downlink LPA data to a BLE module of the terminal through the BLE module.
In step S3012, the BLE module of the terminal passes through the downstream LPA data to the LPA component.
In step S3014, the LPA component writes the processed downstream LPA data into the eSIM card.
In this embodiment, the BLE module may perform unpacking processing on the data, and the specific processing manner may refer to the foregoing embodiment, which is not described herein again.
By the method of the above embodiment, the LPA can be supported on the terminal side.
FIG. 3B is a flowchart illustrating a card writing method according to further embodiments of the invention. In this embodiment, the terminal does not have an LPA component, which is located on the card writing device. As shown in FIG. 3B, the card writing method of this embodiment includes steps S3102-3114.

In step S3104, the LPA component of the card writing device encapsulates the upstream data from the terminal.
In step S3106, the card writing device transmits the encapsulated upstream LPA data to the server.
In step 3108, the card writing device receives the downstream LPA data sent by the server.
In step S3110, the card writing device decapsulates the downstream LPA data using the LPA component.
In step S3112, the card writing device sends the decapsulated downlink data to the terminal by using a BLE module.
In step S3114, the terminal writes the downlink data received through the BLE module into the eSIM card.
In this embodiment, the BLE module may perform unpacking processing on the data, and the specific processing manner may refer to the foregoing embodiment, which is not described herein again. The main transmission process is indicated by dashed lines.
By the method of the embodiment, under the condition that the terminal does not have the LPA component, the card writing data can assist in LPA packaging and decapsulation operations, and the application scope of the card writing method is further improved.
In some embodiments, the data issued by the eSIM card is a card packet group. The terminal may set an APDU (Application Protocol Data Unit) module between the eSIM card and the BLE module to perform packet unpacking processing. For example, on the basis of the embodiment of fig. 3B, the embodiment may further include steps S3100 and S3101, and step S3114 may be replaced with step S3113, as shown in fig. 3C.
In step S3100, the terminal uses the APDU component to reassemble the uplink card data packet group including the request information from the embedded smart card, so as to obtain the uplink data including the request information.
In step S3101, the APDU component of the terminal transmits the uplink data to the BLE module of the terminal.
For a specific implementation of steps S3102 to S3112, refer to fig. 3B, which is not described herein again.
In step S3113, the terminal splits downlink data including the response information from the card writing device into a downlink card packet group by using the APDU component, and writes the downlink card packet group into the eSIM card through the card writing module.
In some embodiments, the terminal may send a broadcast signal, and the broadcast signal may include an indication that the terminal is in a to-be-written state, so that the card writing device authenticates the terminal in response to acquiring the broadcast signal of the terminal. For example, the terminal may use broadcast packets of BLE to show the card writing device that it is in an over-the-air number writing state. The turned-on BLE module may be in a broadcast state all the time when not in a connected state, and the broadcast data may include a service identifier and a device vendor identifier.
