Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a multi-module communication system and a data processing method. Background Art

[0002] In the past two years, Cat.1 has been highly praised by operators due to its advantages such as low cost, low power consumption and good signal coverage. "Cat.X" refers to the Long Term Evolution User Equipment-Category (LTE UE-Category). Cat.X is used to measure the wireless performance of user terminal equipment. Cat.1 supports terminal downlink rates of up to 10Mbps, so that Internet of Things (IoT) devices can be connected to the LTE network with lower power consumption and lower cost. Operators do not need to upgrade the network, only simple parameter configuration is required to allow Cat.1 terminals to access the network.

[0003] At present, there are two application modes of Cat.1 communication module: Cat.1 communication module is used independently using Open CPU architecture, or Cat.1 communication module uses microcontroller unit (MCU) + communication module architecture, and an external MCU (such as STM32F1, etc.) controls the Cat.1 communication module through AT commands.

[0004] However, the Cat.1 communication module communication system in the prior art has only one Cat.1 communication module communication outlet. In scenarios with large uplink data such as video scenarios, data blocking may occur, resulting in increased latency, data loss, and other problems, and the communication rate is low. Summary of the invention

[0005] The present application provides a multi-module communication system and a data processing method to solve the technical problem that the Cat.1 communication module communication system in the prior art has only one Cat.1 communication module communication outlet, and in scenarios with large uplink data such as video scenarios, data blocking may occur, resulting in increased delay, data loss, and low communication rate.

The system can establish a mathematical model in the first Cat.1 communication module to locally determine the bandwidth requirement, and then divert the data to the second Cat.1 communication module. Compared with the communication system with one Cat.1 communication module, it solves the problem of insufficient cache size of a single module, and can meet the scenarios with large uplink data such as video scenes. Even if the uplink data is large, by diverting the data to the second Cat.1 communication module, problems such as increased delay and data loss caused by data blocking can be avoided, thereby improving the communication rate and communication stability.

The first Cat.1 communication module can control the data transmission and sending of the system as a master control node. When uplink data needs to be sent, the first Cat.1 communication module encapsulates the data and determines the cache and sending capacity of the first Cat.1 communication module based on the encapsulated data packet to be sent. If the first Cat.1 communication module itself generates data congestion when sending data, then the data packet to be sent can be sub-packetized, and part of the sub-packetized data can be sent to the second Cat.1 communication module to reduce transmission pressure. By starting the second Cat.1 communication module, efficient data transmission and load balancing are achieved, avoiding the problem of insufficient cache of a single module and improving the communication rate.

When the first Cat.1 communication module has downlink data to receive, it is determined whether the data has a subpacketization mark.

DETAILED DESCRIPTION

[0076] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0077] The terms "first", "second", "third", and "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.

[0078] Cat.1 belongs to the 4G series and can fully reuse existing 4G resources. With the development of the mature 4G industry chain, Cat.1, as a low-end version of 4G, only needs to make a small change to the existing 4G products to quickly launch it to the market and reduce costs to meet the industry's expected range. Cat.1 is a user terminal level configured with the lowest version parameters, allowing the industry to design low-end 4G terminals at a low cost. Compared with NB-IoT and 2G modules, Cat.1 has advantages in network coverage, speed and latency; compared with traditional Cat.4 modules, it has the advantages of low cost and low power consumption. At the same time, Cat.1 is suitable for the current home 4G network and is very suitable for application scenarios that require low-cost performance and small coverage. However, its medium rate has become its advantage over NB-IoT, but it has also become a shortcoming in some application scenarios such as video scenarios or other scenarios with more flexible rate requirements. There is only one Cat.1 module for the communication outlets of Mode 1 and Mode 2, so the rate is limited to this Cat.1 module. In some scenarios with large uplink data (especially video scenarios), data will be blocked, resulting in increased delay or even data loss. In the prior art, Cat.1 communication modules are mostly used alone, and the module's cache is limited by the Cat.1 communication module, and the module's cache is generally small; in addition, Cat.1 modules have lower power consumption and cost than CAT.4 modules, and therefore have been highly recommended recently. In some scenarios where multiple channels of video are very active, it is sufficient to use Cat.1 modules on a regular basis, but it is powerless when multiple channels of video are active at the same time. If you use CAT.4 modules on a regular basis, firstly, the power consumption will be relatively large, and secondly, the cost will be higher.

[0079] In order to solve the above technical problems, an embodiment of the present application provides a multi-module communication system and a data processing method, which are provided with two Cat.1 communication modules, and use a dual Cat.1 communication module communication mode that combines the Open CPU architecture and the AT architecture. After establishing a mathematical model in the first Cat.1 communication module to locally judge the bandwidth requirement, the data can be diverted to the second Cat.1 communication module to achieve efficient communication.

[0080] The technical solution of the present application is described below by taking several embodiments as examples, and the same or similar concepts or processes may not be repeated in some embodiments.

[0081] Optionally, Figure 1 A schematic diagram of the structure of a multi-module communication system provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the multi-module communication system includes a first Cat.1 communication module 101 , a second Cat.1 communication module 102 , a UART 103 , a GPIO 104 and a base station 105 .

[0082] The first Cat.1 communication module 101 and the second Cat.1 communication module 102 are connected to the base station 105 respectively.

[0083] The first Cat.1 communication module 101 establishes a first connection with the second Cat.1 communication module 102 via the universal asynchronous receiver / transmitter 103 .

[0084] The first Cat.1 communication module 101 and the second Cat.1 communication module 102 establish a second connection through the universal input / output port 104 .

[0085] The first Cat.1 communication module 101 implements communication through the Open CPU mode, and the second Cat.1 communication module 102 implements communication through the AT command mode.

[0086] Optionally, the multi-module communication system also includes a switching circuit.

[0087] The switch circuit is connected to the first Cat.1 communication module 101 and the second Cat.1 communication module 102 through GPIO respectively, and the switch circuit is used to control the opening and closing of the second Cat.1 communication module 102 according to the control instruction of the first Cat.1 communication module 101.

[0088] Here, the multi-module communication system in the embodiment of the present application also includes a switching circuit, which is arranged between the first Cat.1 communication module and the second Cat.1 communication module. The first Cat.1 communication module can realize the opening and closing control of the second Cat.1 communication module through this switching circuit to achieve stable and reliable data diversion, further improving the communication rate and communication stability.

[0089] Optionally, the switching circuit includes a transistor.

[0090] Among them, the switching transistor has the characteristics of long life, safety and reliability, no mechanical wear, fast switching speed and small size. By realizing the switching circuit through the transistor, a very small current can be used to control the on and off of a large current, thus solving the system cost and circuit loss.

[0091] Optionally, the first Cat.1 communication module 101 and the second Cat.1 communication module 102 are arranged on the same printed circuit board.

[0092] Here, the embodiment of the present application sets the first Cat.1 communication module and the second Cat.1 communication module on the same printed circuit board (PCB), achieving uplink and downlink load balancing, while saving the volume of the multi-module communication system, thereby saving costs and reducing costs and losses.

[0093] The multi-module communication system provided in the embodiment of the present application is provided with two Cat.1 communication modules, and the two Cat.1 communication modules can be connected to the base station respectively, and use the dual Cat.1 communication module communication mode combining the Open CPU architecture and the AT architecture. The system can establish a mathematical model in the first Cat.1 communication module to locally determine the bandwidth demand, and then divert the data to the second Cat.1 communication module. Compared with the communication system with one Cat.1 communication module, the problem of insufficient cache size of a single module is solved, and the scenarios with large uplink data such as video scenes can be met. Even if the uplink data is large, by diverting the data to the second Cat.1 communication module, the problems of increased delay and data loss caused by data blocking can be avoided, thereby improving the communication rate and communication stability.

[0094] It is understandable that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the architecture of the multi-module communication system. In other feasible implementations of the present application, the above architecture may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently, which can be determined according to the actual application scenario and is not limited here.

Ordinary technicians in this field can know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0096] Figure 2 A flowchart of a data processing method provided in an embodiment of the present application. The execution subject of the embodiment of the present application may be Figure 1 The first Cat.1 communication module 101 or the server of the first Cat.1 communication module 101 in the embodiment shown may be specifically executed by a subject according to the actual application scenario. Figure 2 As shown, the method comprises the following steps:

[0097] S201: In response to a data sending request, obtain data to be sent.

[0098] S202: Encapsulate the data to be sent to obtain a data packet to be sent.

[0099] Optionally, when uplink data needs to be sent, the first Cat.1 communication module first encapsulates and packages the data and puts them into a sending buffer.

[0100] S203: Determine whether the data packet to be sent needs to be split.

[0101] Optionally, determining whether the data packet to be sent needs to be split includes:

[0102] Put the data packet to be sent into the transmission buffer of the first Cat.1 communication module; take the first preset time as the time node, and determine the remaining buffer size of the first Cat.1 communication module at each time node; if within the second preset time, the remaining buffer size of the first Cat.1 communication module shows a decreasing trend at each time node, and the decreasing amount of the remaining buffer size is greater than the preset decreasing threshold, it is determined that the data packet to be sent needs to be split.

[0103] It can be understood that the first preset time, the second preset time, and the preset decreasing threshold here can all be determined according to the actual situation, and the embodiments of the present application do not make specific limitations on this.

[0104] Exemplarily, taking B seconds (for example, B = 0.5 seconds) as a node to judge the current remaining buffer size. If the remaining buffer size shows a decreasing trend for consecutive C seconds (for example, C = 5 seconds), and the decreasing amount within C seconds exceeds A*E (A is the total buffer size, and E is a constant, which can be 1 / 2, 2 / 3, etc.), then start the second Cat.1 communication module through GPIO, and then split the split data X into X1 and X2 (X1 < X2, and X1 and X2 have split flags), put X1 into the transmission buffer; send X2 to the second Cat.1 communication module through UART.

[0105] It can be understood that the above B, C, A, and E are all thresholds that can be determined according to the actual situation.

[0106] Here, the embodiments of the present application determine whether to split the data through the change trend of the remaining buffer size, so as to accurately judge whether the buffer size of the first Cat.1 communication module matches the memory size occupied by the data packet to be sent, thereby effectively avoiding data blocking and improving the accuracy, reliability, and efficiency of data transmission and data communication.

[0107] S204: If it is determined that splitting is required, split the data packet to be sent into a first data packet and a second data packet.

[0108] Optionally, if it is determined that splitting is required, splitting the data packet to be sent into a first data packet and a second data packet includes:

[0109] If it is determined that splitting is required, split the data packet to be sent into a first data packet and a second data packet, where the first data packet and the second data packet carry split identifiers.

[0110] Optionally, the size of the first data packet is smaller than that of the second data packet.

[0111] Here, when the embodiment of the present application performs packet processing on the data packet to be sent, a packet identifier is added to the first data packet and the second data packet after packetization, so that complete data can be obtained according to the packet identifier when the data is received, thereby ensuring the integrity and reliability of the communication.

[0112] S205: putting the first data packet into the sending buffer of the first Cat.1 communication module, starting the second Cat.1 communication module, and sending the second data packet to the second Cat.1 communication module through the universal asynchronous receiver-transmitter.

[0113] An embodiment of the present application provides a data processing method, which can realize data sending and receiving through a multi-module communication system including a first Cat.1 communication module and a second Cat.1 communication module. The first Cat.1 communication module can control the data transmission and sending of the system as a master control node. When uplink data needs to be sent, the first Cat.1 communication module encapsulates the data and determines the cache and sending capacity of the first Cat.1 communication module based on the encapsulated data packet to be sent. If the first Cat.1 communication module itself generates data congestion when sending data, the data packet to be sent can be sub-packetized, and a part of the sub-packetized data can be sent to the second Cat.1 communication module to reduce transmission pressure. By starting the second Cat.1 communication module, efficient data transmission and load balancing are achieved, avoiding the problem of insufficient cache size of a single module and improving the communication rate.

[0114] In some possible implementations, the embodiment of the present application may also implement data reception. Optionally, the method further includes:

[0115] The first to-be-received data sent by the second Cat.1 communication module is received through the universal asynchronous receiver / transmitter, wherein the to-be-received data is obtained by the second Cat.1 communication module in response to a downlink data receiving request.

[0116] Optionally, the above method further includes:

[0117] In response to a downlink data receiving request, second data to be received is obtained; whether the second data to be received carries a subpacket identifier is determined; if the second data to be received does not carry a subpacket identifier, the second data to be received is received.

[0118] Optionally, after determining whether the second data to be received carries a subpacket identifier, it also includes: if the second data to be received carries a subpacket identifier, placing the second data to be received into a receiving cache; after receiving the third data to be received sent by the second Cat.1 communication module, repackaging the second data to be received and the third data to be received, wherein the third data to be received carries a subpacket identifier corresponding to the second data to be received.

[0119] Exemplarily, the data receiving process is as follows:

[0120] When the second Cat.1 communication module has downlink data to receive, the data Y2 is transmitted to the first Cat.1 communication module via UART.

[0121] When the first Cat.1 communication module has downlink data to receive, it determines whether the data has a subpacketization mark. If not, it receives and processes it normally; if so, it puts the data Y1 into the receiving buffer and waits for the data from the second Cat.1 communication module.

[0122] When the first Cat.1 communication module receives the second Cat.1 communication module and determines the end mark, it searches for Y1 from the receiving buffer and reassembles Y1 and Y2.

[0123] Among them, Y1 and Y2 are the data received by the communication module.

[0124] Here, the embodiment of the present application can realize data reception through a multi-module communication system. When the second Cat.1 communication module has downlink data to receive, the data is transmitted to the first Cat.1 communication module through UART. When the first Cat.1 communication module has downlink data to receive, it is determined whether the data has a subpacketization mark. If not, it is received and processed normally; if so, the data is placed in the receiving cache, waiting for the data of the second Cat.1 communication module, realizing data reorganization and restoration, and realizing data reception completely and efficiently.
