Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular, to an adaptive message processing method based on the TCP protocol. Background Art

[0002] At present, for NB-IoT terminals using the TCP protocol, when it is necessary to ensure the quality of message transmission, multiple retransmissions of messages and ACK (or RSP) messages at the protocol layer are used to ensure communication between the NB-IoT terminal and the Internet of Things platform. When the Internet of Things platform sends certain instructions to the NB-IoT terminal, a maximum number of retransmissions and a response timeout are defined for each sent instruction. Whenever the response timeout is reached and no response message is received, a retransmission is performed once and the timeout is doubled until the corresponding ACK (or RSP) is received or the maximum number of transmissions is reached and the response is still timed out. Therefore, there will be a scenario where the same downlink instruction from the Internet of Things platform is received and processed by the NB-IoT terminal multiple times. This scenario will cause some unnecessary resource consumption to the NB-IoT terminal, especially in scenarios where the instruction processing flow is relatively complex. In the prior art, reducing unnecessary resource consumption can generally only be processed at the application layer of the TCP protocol, but at the same time, it will change the usage mode of the NB-IoT terminal of the TCP protocol.

[0003] Therefore, there is a need for a solution that can simplify the downlink instruction response process and reduce the resource consumption of the NB-IoT terminal without changing the usage mode of the NB-IoT terminal of the TCP protocol. Summary of the Invention

[0045] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0046] Refer to Figure 1 , an embodiment of the present invention provides an adaptive message processing method based on the TCP protocol, which specifically includes the following steps:

[0047] Step S100: Receive a first downlink instruction sent by the Internet of Things platform.

[0048] Specifically, the NB-IoT terminal can receive the downlink instruction sent by the Internet of Things platform, and the downlink instruction sent by the Internet of Things platform can be used as the first downlink instruction.

[0049] Step S110: Match the first downlink instruction with a second downlink instruction in a preset cache queue in the adaptation layer. The cache queue is used to cache multiple first response messages and multiple second downlink instructions sent by the Internet of Things platform.

[0050] Specifically, a cache queue can be added in advance in the adaptation layer of the NB-IoT terminal to cache multiple downlink instructions recently sent by the Internet of Things platform. The downlink instruction can be used as the second downlink instruction. Among them, the number of second downlink instructions that can be cached in the cache queue can be configured by the user himself, and the present invention does not make strict limitations. In addition, the response messages corresponding to each second downlink instruction can also be cached in the cache queue as the first response messages.

[0051] Furthermore, the first downlink instruction can be matched in the cache queue to determine whether there is a second downlink instruction that meets the matching conditions in the cache queue.

[0052] Step S120: If there is a target downlink instruction in the second downlink instructions that matches the first downlink instruction, and there is a target response message corresponding to the first downlink instruction in the first response message, then send the target response message to the IoT platform.

[0053] Specifically, if there is a downlink instruction in the multiple second downlink instructions in the cache queue that matches the first downlink instruction, this downlink instruction can be used as the target downlink instruction. And if there is a target response message corresponding to the first downlink instruction in the multiple first response messages in the cache queue, it can be considered that the NB-IoT terminal has received the first downlink instruction and executed it at least once. Therefore, the target response message can be directly used as the response message corresponding to the first downlink instruction, and then the target response message is uploaded to the IoT platform, thus completing the processing flow of the first downlink instruction.

[0054] The present invention can simplify the message processing flow of the NB-IoT terminal for downlink instructions, without repeatedly executing the downlink instructions sent by the IoT platform multiple times. Without changing the usage mode of the NB-IoT terminal of the TCP protocol, the technical effect of reducing the resource consumption of the NB-IoT terminal can be achieved.

[0055] Furthermore, if there is no target response message corresponding to the first downlink instruction in the cache queue, the embodiments of the present invention can also add the following process:

[0056] Specifically, if there is a target downlink instruction in the second downlink instructions that matches the first downlink instruction, and there is no target response message corresponding to the first downlink instruction in the first response message, it can be considered that the NB-IoT terminal is processing the first downlink instruction previously sent by the IoT platform. Therefore, the message processing flow of the current first downlink instruction can be ended.

[0057] Furthermore, if there is no target downlink instruction in the cache queue that matches the first downlink instruction, the embodiments of the present invention can also add the following process:

[0058] S1: If there is no target downlink instruction in the second downlink instructions that matches the first downlink instruction, then parse the first downlink instruction through the TCP protocol layer to obtain a parsed message.

[0059] S2: Transparently transmit the parsed message to the application service layer through the adaptation layer.

[0060] S3: Complete the service operation corresponding to the parsed message through the application service layer and obtain a second response message.

[0061] S4. Transparently transmit the second response message to the TCP protocol layer through the adaptation layer.

[0062] S5. Perform compact binary encoding of the second response message through the TCP protocol layer, and send the encoded second response message to the IoT platform.

[0063] Specifically, if there is no target downlink instruction in the cache queue that matches the first downlink instruction, the NB-IoT terminal can perform the Figure 2 processing flow shown. Among them, when there is no target downlink instruction in the cache queue that matches the first downlink instruction, the processing flow performed by the NB-IoT terminal on the first downlink instruction can be used as the default process.

[0064] Specifically, the above default process may include: after the TCP protocol layer receives the first downlink instruction, it parses it. After the parsing of the first downlink instruction is completed, a parsed message is obtained. Then, the parsed message is handed over to the adaptation layer, and the adaptation layer transparently transmits the parsed message to the application service layer for processing. The application service layer completes corresponding service operations according to the content of the parsed message, obtains a second response message, and hands the second response message to the adaptation layer. The adaptation layer transparently transmits the second response message to the TCP protocol layer, and the TCP protocol layer performs compact binary encoding again. A specific example diagram of the encoding can be referred to Figure 3 , and finally send the encoded second response message to the IoT platform.

[0065] Considering that the IoT platform may send the first downlink instruction to the NB-IoT terminal again later, the first downlink instruction and the second response message corresponding to the first downlink instruction can be cached in the cache queue. When the NB-IoT terminal receives the first downlink instruction again later, it can directly obtain the second response message from the cache queue and send it to the IoT platform, which can save the processing flow of executing the first downlink instruction again.

[0066] In some embodiments of the present invention, the above step S110, the process of matching the first downlink instruction with the second downlink instruction in the preset cache queue in the adaptation layer is introduced. Next, the matching process will be further described.

[0067] Specifically, the matching process may include:

[0068] S1. Parse the first downlink instruction through the TCP protocol layer to obtain the ServiceID and MsgID of the first downlink instruction.

[0069] S2. Register the response callback function of the first downlink instruction in the adaptation layer.

[0070] S3. Use the response callback function to match the ServiceID and MsgID of the first downlink instruction with the ServiceID and MsgID of the second downlink instruction in the cache queue.

[0071] S4. If the ServiceID of the first downlink instruction is the same as the ServiceID of the second downlink instruction, and the MsgID of the first downlink instruction is the same as the MsgID of the second downlink instruction, it is determined that the first downlink instruction matches the second downlink instruction.

[0072] Specifically, the cacheable number of the cache queue pre-added in the adaptation layer can be set by the user. In the embodiment of the present invention, taking the cacheable number as 5 as an example, refer to Figure 4 , each node of the cache queue can store the following information: the MsgID of the second downlink instruction, the ServiceID of the second downlink instruction, and the first response message corresponding to the second downlink instruction, etc. In addition, other information specified by the user can also be saved in the cache queue to adapt to some specific scenarios.

[0073] Among them, when the cache queue is full, a replacement algorithm can be used to replace the second downlink instruction and the above-related data in the cache queue. The replacement algorithm can use the FIFO (First Input First Output) algorithm, or the LRU (Least Recently Used) algorithm, etc., as well as other optional replacement algorithms.

[0074] The matching process between the first downlink instruction and the second downlink instruction in the cache queue may include:

[0075] Register the response callback function of the first downlink instruction in the adaptation layer. After the TCP protocol layer parses the first downlink instruction to obtain the ServiceID and MsgID of the first downlink instruction, it is passed to the response callback function. In the response callback function, the ServiceID and MsgID of the first downlink instruction are matched with the data in the cache queue. The matching content includes the ServiceID and MsgID of the second downlink instruction. When the ServiceID and MsgID of the first and second downlink instructions are both the same, it can be considered that the two match.

[0076] Since, in most cases, the MsgID is required by the specification to be strictly incremented, and considering the situation that the NB-IoT terminal may be connected to multiple Internet of Things platforms at the same time, therefore, within the set time period, the first downlink instructions with the same MsgID sent by the Internet of Things platform with the same source address can all be considered as the same downlink instruction.

[0077] Next, a specific example will be used to illustrate the process of the adaptive message processing based on the TCP protocol according to the present invention. Refer to Figure 5 , Figure 5 FIG. shows a timing diagram of the TCP message adaptive processing provided by an embodiment of the present invention.

[0078] Specifically, a cache queue is pre-added to the adaptation layer of the NB-IoT terminal. The cache queue can be used to cache the N (N is configurable) second downlink instructions and the corresponding NB-IoT terminal response messages recently sent by the IoT platform. When the cache queue is full, a replacement algorithm (such as FIFO, LRU, etc.) can be used to replace the second downlink instructions and their related data in the cache queue. When the NB-IoT terminal receives the first downlink instruction sent by the IoT platform, the first downlink instruction can be first matched with the second downlink instructions in the cache queue in the adaptation layer. According to different matching results, there can be the following different processing flows: If no matching target downlink instruction is found, after caching the first downlink instruction in the cache queue, continue to process the message corresponding to the first downlink instruction according to the default process, and store the response message of the first downlink instruction into the corresponding node of the cache queue; If a matching target downlink instruction is found but there is no corresponding target response message, it is considered that the first downlink instruction is being processed, and then the current message processing flow can be ended; If a matching target downlink instruction is found and the cache queue contains the corresponding target response message, the target response message can be directly returned to the IoT platform, and then the processing flow of this message is ended.
