[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will elaborate on each embodiment of the present application with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that in each embodiment of the present application, many technical details are proposed to help readers better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can still be implemented. The following division of each embodiment is for convenience of description and should not constitute any limitation on the specific implementation manner of the present application. Each embodiment can be combined and cross-referenced with each other on the premise of not being contradictory.

[0053] Embodiments of the present application relate to a network access communication method, which is applied to a gateway device. The gateway device is used to communicate with a peripheral device. As Figure 1 shown, it specifically includes the following steps.

[0054] Step 101: Determine a first scrambling code according to the address of the gateway device, the total number of times in the current time group, and the network key of the gateway device.

[0055] Among them, the address of the gateway device is used to identify the uniquely corresponding gateway device, and the address of the gateway device can be represented as InitID.

[0056] The total number of times in the current time group can be represented as NextEvtCnt. Among them, the communication between the gateway device and the peripheral device is divided into multiple time groups. Every time a time group passes, the total number of times in the current time group is incremented by one. Among them, each peripheral device has a fixed time group.

[0057] The network key of the gateway device is pre-set. The user can pre-set the network key of the gateway device in the gateway device, and the network key of the gateway device can be represented as netkey1. In an exemplary implementation, the lower 8 bytes of the network key of the gateway device are pre-stored network keys, and the upper 8 bytes are all 0.

[0058] In an exemplary implementation, the length of the first scrambling code can be 16 bytes.

[0059] Step 102: Select a byte segment formed by bytes at a preset number of positions in the first scrambling code as the first check code.

[0060] In an exemplary implementation, the length of the first check code is 4 bytes. A byte segment formed by the lower 4 bytes of the first scrambling code can be selected as the first check code. Of course, it can also be other preset positions, which are not specifically limited in the embodiments of the present application. The first check code can be represented as NetMic1.

[0061] Step 103: Send the first check code, the address of the gateway device, and the total number of times in the current time group to the peripheral device.

[0062] In the embodiments of the present application, the gateway device sends a source packet to the peripheral device. The source packet contains the first check code, the address of the gateway device, and the total number of times in the current time group. After receiving the source packet, the peripheral device determines a second check code according to the network key of the peripheral device, the address of the gateway device in the source packet, and the total number of times in the current time group in the source packet. The method for determining the second check code is the same as the method for the gateway device to determine the first check code, and will not be elaborated here.

[0063] The network key of the peripheral device is pre-set. The user can pre-set the network key of the peripheral device in the peripheral device, and the network key of the peripheral device can be represented as netkey2.

[0064] After the peripheral device determines the second check code, it compares the second check code with the first check code in the source packet. If the second check code and the first check code are the same, the peripheral device can access the network.

[0065] In the embodiments of the present application, the gateway device and the peripheral device are configured to access the network through the network key. Only when the network key of the peripheral device is the same as the network key of the gateway device can it be ensured that the first check code and the second check code are the same, thereby completing the network access operation of the peripheral device for the gateway device. The network configuration for this network access is simple and easy to use.

[0066] Such as Figure 2As shown, all gateway devices and all peripheral devices can implement a large-scale network in hybrid mode by using the same network key. There are multiple gateway devices and multiple peripheral devices in this large-scale network in hybrid mode; as Figure 3 As shown, configuring different network keys for different gateway devices can implement a large-scale network in independent mode. There is one gateway device and multiple peripheral devices in this large-scale network in independent mode. That is, the embodiments of the present application can change different network modes by setting different network keys, and changing the network mode is relatively simple and flexible. Only the network key needs to be configured, and no other hardware facilities are required. Therefore, the applicability of the network access communication method of the present application is relatively strong.

[0067] In the embodiments of the present application, the gateway device determines a first scrambling code according to the address of the gateway device, the total number of times in the current time group, and the network key of the gateway device; selects a byte segment formed by bytes at a preset number of positions in the first scrambling code as the first check code; and sends the first check code, the address of the gateway device, and the total number of times in the current time group to the peripheral device, so that the peripheral device determines a second check code according to the address of the gateway device, the total number of times in the current time group, and the network key of the peripheral device, and when the second check code is the same as the first check code, the network access operation of the peripheral device for the gateway device is completed. The network configuration for network access is simple and easy to use, and changing the network mode is relatively simple and flexible. The applicability of this network access communication method is relatively strong.

[0068] Based on the above Figure 1 Based on the above network access communication method shown, the embodiments of the present application also provide a network access communication method. In the application scenario of a logistics station, the gateway device is a logistics terminal device, which can be a logistics terminal held by a courier. Correspondingly, the peripheral device is set on the logistics item, and the peripheral device on each logistics item is communicatively connected to the logistics terminal device. Of course, in other application scenarios, the gateway device and the peripheral device can also be other devices, which are not specifically limited in the embodiments of the present application.

[0069] Based on the above Figure 1 Based on the above network access communication method shown, the embodiments of the present application also provide a network access communication method, as Figure 4 As shown, step 101, determining the first scrambling code according to the address of the gateway device, the total number of times in the current time group, and the network key of the gateway device specifically includes the following steps.

[0070] Step 401, determining the plaintext according to the address of the gateway device and the total number of times in the current time group.

[0071] In an exemplary implementation, the lower 0-3 bytes of the plaintext are the preset common synchronization word 0x6deb98e8, the lower 4-7 bytes are the total time of the current time group, the 8-13 bytes are the address of the gateway device, and the remaining 14-216 bytes are all 0.

[0072] Step 402: Input the plaintext and the network key of the gateway device into a preset encryption engine to obtain a first scrambling code.

[0073] Among them, the preset encryption engine can be an aes-128 encryption engine. The input of the aes-128 encryption engine is a 16-byte key and a 16-byte plaintext, and the generated output is a 16-byte ciphertext, which belongs to hardware encryption. Of course, the first scrambling code can also be obtained by encrypting through other encryption engines, and no specific limitation is made in the embodiments of the present application.

[0074] In the embodiments of the present application, according to the address of the gateway device and the total time of the current time group, the plaintext is determined, and the plaintext and the network key of the gateway device are input into a preset encryption engine to obtain a first scrambling code, and then the first check code can be further determined through the determined first scrambling code.

[0075] In the above Figure 1 Based on the above-mentioned network access communication method, the embodiments of the present application further provide a network access communication method. After step 101 of determining the first scrambling code according to the address of the gateway device, the total time of the current time group, and the network key of the gateway device, the following steps are further included.

[0076] Scramble the current original PDU (Protocol Data Unit) field of the gateway device according to the first scrambling code to obtain a scrambled PDU field.

[0077] In an exemplary implementation, the first scrambling code can be subjected to a bitwise exclusive OR calculation with the current original PDU field of the gateway device to calculate and obtain a scrambled PDU field.

[0078] The current original PDU field is the communication basic data between the peripheral device and the gateway device, that is, normal communication between the peripheral device and the gateway device can be carried out only after the communication basic data exists in the peripheral device.

[0079] When the gateway device sends the first check code, the address of the gateway device, and the total time of the current time group to the peripheral device, it also sends the scrambled PDU field to the peripheral device, that is, the source packet sent by the gateway device to the peripheral device includes both the first check code, the address of the gateway device, the total time of the current time group, and the scrambled PDU field.

[0080] After the peripheral device determines the second check code and determines that the second check code is the same as the first check code, after completing the network access operation of the peripheral device for the gateway device, continue to determine the second scrambling code according to the network key of the peripheral device, the address of the gateway device in the source packet, and the total number of times of the current time group in the source packet, and determine the current original PDU field according to the second scrambling code and the scrambled PDU field. Among them, the method for determining the second scrambling code is the same as the method for the gateway device to determine the first scrambling code. First, determine the plaintext, and then obtain the second scrambling code according to the plaintext and the network key of the peripheral device. The method for determining the current original PDU field is the same as the method for the gateway device to obtain the scrambled PDU field. Perform a bitwise exclusive OR calculation on the second scrambling code and the scrambled PDU field to obtain the current original PDU field.

[0081] After the peripheral device calculates and obtains the current original PDU field, store the current original PDU field, so that normal communication and interaction can be carried out between the gateway device and the peripheral device.

[0082] In the embodiment of the present application, after the network access operation, determine the current original PDU field according to the scrambled PDU field in the source packet and store it, so that the peripheral device can communicate normally with the gateway device after network access.

[0083] Based on the network access communication method in the above embodiment, the embodiment of the present application further provides a network access communication method, as Figure 5 shown, the above method further includes the following steps.

[0084] Step 501, determine the first signal synchronization word according to the first scrambling code.

[0085] After the peripheral device performs the network access operation and stores the current original PDU field, the gateway device can perform data interaction with the peripheral device. At this time, the gateway device sends a synchronization data packet to the peripheral device, and the synchronization data packet includes request data and the first signal synchronization word. The first signal synchronization word is intercepted from the first scrambling code.

[0086] Step 502, send the first signal synchronization word to the peripheral device.

[0087] After the peripheral device receives the synchronization data packet, compare the first signal synchronization word in the synchronization data packet with the second signal synchronization word calculated by the peripheral device. If the first signal synchronization word is the same as the second signal synchronization word, the peripheral device performs data interaction with the gateway device, that is, the peripheral device determines the response data according to the request data in the synchronization data packet and sends a response packet carrying the response data to the gateway device. After the gateway device receives the response packet, it sends a response confirmation packet to the peripheral device.

[0088] In an embodiment of the present application, the method for the peripheral device to obtain the second signal synchronization word is the same as the method for the gateway device to obtain the first signal synchronization word.

[0089] In an embodiment of the present application, after the peripheral device performs the network access operation and stores the current original PDU field, normal communication data interaction between the peripheral device and the gateway device is carried out according to the first signal synchronization word and the request data.

[0090] Based on the network access communication method in the above Figure 5 shown embodiment, the embodiment of the present application further provides a network access communication method. As Figure 6 shown, in step 501 above, determining the first signal synchronization word according to the first scrambling code further includes the following steps.

[0091] Step 601: Select a first byte segment with a preset length starting from the low bit of the first scrambling code.

[0092] In an exemplary embodiment, starting from the low bit of the scrambling code, 4 bytes can be taken as the first byte segment.

[0093] Step 602: Check the validity of the first byte segment with a preset length according to a preset validity condition.

[0094] Wherein, the preset validity condition is: there is no at least continuous 6 0s or 1s, each byte value cannot be all equal, the number of value flips does not exceed 24 times, and there are at least 2 value flips in the high 6 bits.

[0095] Step 603: If the validity check fails, select a second byte segment with a preset length different from the first byte segment with a preset length from the first scrambling code until the second byte segment with a preset length passes the validity check, and use the second byte segment with a preset length as the first signal synchronization word.

[0096] If the first byte segment does not meet the preset validity condition and the validity check fails, select 4 bytes starting from the low 2 bits of the scrambling code as the second byte segment and continue the validity check. If the validity check of the second byte segment passes, use the 4-byte second byte segment as the first signal synchronization word. If the first byte segment selected from the first scrambling code and each second byte segment do not pass the validity check, a general synchronization word is used. For example, the general synchronization word can be: 0x6deb98e8.

[0097] The embodiment of the application realizes determining the first signal synchronization word according to the first scrambling code by checking the validity of the byte segment in the first scrambling code.

[0098] Based on the network access communication method in the above embodiments, an embodiment of the present application further provides a network access communication method, which is applied to a peripheral device. The peripheral device is used to communicate with a gateway device, such as Figure 7 shown, and specifically includes the following steps.

[0099] Step 701, receive the first check code, the address of the gateway device, and the total number of times in the current time group sent by the gateway device.

[0100] Specifically, the peripheral device receives the source packet sent by the gateway device. The source packet contains the first check code, the address of the gateway device, and the total number of times in the current time group.

[0101] Step 702, determine the second scrambling code according to the network key of the peripheral device, the address of the gateway device, and the total number of times in the current time group.

[0102] Specifically, the peripheral device determines the plaintext according to the address of the gateway device and the total number of times in the current time group in the source packet, and inputs the plaintext and the network key of the peripheral device into a preset encryption engine to obtain the second scrambling code.

[0103] Step 703, select the byte segment formed by the bytes at a preset number of positions in the second scrambling code as the second check code.

[0104] In an exemplary embodiment, the length of the second check code is 4 bytes. The byte segment formed by the lower 4 bytes of the second scrambling code can be selected as the second check code. Of course, it can also be other preset positions, which are not specifically limited in the embodiments of the present application. The second check code can be represented as NetMic2.

[0105] Step 704, if the second check code is the same as the first check code, complete the network access operation of the peripheral device for the gateway device.

[0106] If the second check code is the same as the first check code, the peripheral device can access the network.

[0107] In the embodiments of the present application, network access is configured by configuring the network key on the peripheral device side. When the network key of the peripheral device is the same as the network key of the gateway device, the first check code and the second check code are the same, and then the network access operation of the peripheral device for the gateway device is completed.

[0108] In the above Figure 7 Based on the network access communication method in the shown embodiment, an embodiment of the present application further provides a network access communication method, which is applied to a peripheral device, such as Figure 8 shown, and specifically includes the following steps.

[0109] Step 801, receive the scrambled PDU field sent by the gateway device.

[0110] The source packet sent by the gateway device not only contains the first check code, the address of the gateway device, the total number of times of the current time group, but also contains the calculated scrambled PDU field.

[0111] Step 802, according to the second scrambling code, scramble the scrambled PDU field to obtain the current original PDU field.

[0112] In an exemplary implementation, the second scrambling code can be XOR-calculated with the scrambled PDU field to calculate the current original PDU field, and the current original PDU field is stored. The current original PDU field is the basic communication data between the peripheral device and the gateway device.

[0113] Step 803, receive the first signal synchronization word sent by the gateway device.

[0114] After the network access is completed, the peripheral device and the gateway device communicate normally. Specifically, the gateway device sends a synchronization data packet to the peripheral device, and the synchronization data packet contains the first signal synchronization word and the request data.

[0115] Step 804, determine the second signal synchronization word according to the second scrambling code.

[0116] Specifically, starting from the low bit of the second scrambling code, select a third byte segment with a preset length, and perform a validity check on the third byte segment with the preset length according to the preset validity condition. If the validity check fails, reselect a fourth byte segment with a preset length different from the third byte segment with the preset length from the second scrambling code until the fourth byte segment with the preset length passes the validity check, and use the fourth byte segment with the preset length as the second signal synchronization word.

[0117] Step 805, if the second signal synchronization word is the same as the first signal synchronization word, the peripheral device and the gateway device perform data interaction.

[0118] If the second signal synchronization word is the same as the first signal synchronization word, the peripheral device determines the response data according to the request data in the synchronization data packet, and sends a response packet carrying the response data to the gateway device.

[0119] In the embodiment of the present application, the normal communication data interaction between the peripheral device and the gateway device is completed on the peripheral device side after the peripheral device completes the network access operation.
