Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In order to better understand the technical solutions of the present invention, the following detailed descriptions of the technical solutions of the present invention are provided with the accompanying drawings and the specific embodiments, and it should be understood that the specific features in the embodiments and the examples of the present invention are the detailed descriptions of the technical solutions of the present invention, and are not limitations of the technical solutions of the present invention, and the technical features in the embodiments and the examples of the present invention may be combined with each other without conflict.

The inventors have found through research that the stability of a communication network is often interfered by heterogeneous devices. For example, taking the vehicle-mounted network as an example, the plurality of vehicle-mounted controllers are isomorphic devices, and the data transmission mode, the data transmission protocol and the data transmission frequency band of the vehicle-mounted controllers are all the same, so that the vehicle-mounted network formed by the plurality of vehicle-mounted controllers has sufficient network stability when the vehicle-mounted network operates alone.

However, in practical applications, the internet of vehicles is not operated separately. The instant messaging network formed by interaction of the mobile terminal can interfere with the internet of vehicles, and accordingly, the mobile terminal is a heterogeneous device compared with the vehicle-mounted controller, and under the condition, the stability of the internet of vehicles is easily influenced by the mobile terminal.

As can be seen from the above, the stability of the communication network may be disturbed by the intrusion of heterogeneous devices.

Therefore, the embodiment of the invention provides a communication processing method based on an internet of vehicles and an electronic device, which can effectively improve the problems.

Referring to fig. 1, a schematic structural diagram of a communication processing system 100 according to an embodiment of the present invention is shown, the system including an electronic device 1, a first terminal 2, and a second terminal 3. The number of the first terminals 2 and the second terminals 3 may be multiple, and the electronic device 1 and the multiple first terminals 2 are communicatively connected to each other to form a first communication network.

Further, the second terminal 3 is a heterogeneous device with respect to the first terminal 2, and the second communication network where the second terminal 3 operates may interfere with the first communication network, thereby affecting the stability of the first communication network and the normal service development of the first terminal 2. For this reason, the electronic device 1 shown in fig. 1 may perform the communication processing method based on the in-vehicle network as shown in fig. 2 to improve the above-described problem. It will be appreciated that the method may specifically include the following.

Step S21, periodically receiving the first communication signal sent by each first terminal in the first communication network, obtaining a first position at which each first terminal sends a corresponding first communication signal, and determining a first signal strength of each first communication signal.

In this embodiment, the electronic device 1 may be understood as a device that performs status detection on a first communication network, and the electronic device 1 may perform communication status adjustment on any one first terminal 2 in the first communication network to ensure normal service development of the first terminal 2.

In this embodiment, the electronic device 1 may receive the first communication signal and acquire the first location at set time intervals. The setting time interval may be adjusted according to the number of the first terminals, for example, if the number of the first terminals 2 is small, the setting time interval may be extended, and if the number of the first terminals 2 is large, the setting time interval may be shortened.

In this embodiment, the first communication signal may be a detection signal sent by the first terminal 2 during communication interaction, and the first position may be latitude and longitude information, or may be three-dimensional coordinate information of the first terminal 1 determined based on a world coordinate system, which is not limited herein. The signal strength is used to characterize the maximum communication range of the first terminal 2.

Step S22, generating a current communication network topological graph according to a first position corresponding to each first terminal, and mapping a first signal strength corresponding to each first terminal to the current communication network topological graph based on a network node corresponding to each first terminal in the current communication network topological graph to obtain a node coverage range corresponding to a network node corresponding to each first terminal in the current communication network topological graph; and obtaining a communication coverage area of the first communication network according to the current network topology map and a node coverage area corresponding to each network node in the current network topology map.

In the present embodiment, the current communication network topology is used to describe a first communication network formed by a plurality of first terminals. The node coverage can be obtained according to a mapping relationship between the position of the network node and the first position of the first terminal corresponding to the network node.

Step S23, determining a communication parameter of each first terminal and mapping the communication parameter of each first terminal to the current communication network topology map, so as to obtain a stability feature vector for characterizing a network node corresponding to each first terminal in the current communication network topology map.

In this embodiment, the communication parameters of the first terminal may include a communication protocol, a message throughput, a communication frequency, a data transmission format, and the like. The stability feature vector is used for characterizing the communication stability of the network node, that is, the first terminal, and the stability feature vector is a multi-dimensional vector and can describe the communication stability of the first terminal from multiple dimensions.

Step S24, periodically detecting whether a second communication signal broadcasted by a second terminal exists according to the communication coverage area, if so, iterating the second location of the second terminal based on the second communication signal, the second location of the second terminal when the second terminal broadcasts the second communication signal, and a dynamic parameter of a second communication network where the second terminal is located, which is requested from a target electronic device, to obtain a location movement trajectory of the second terminal.

In this embodiment, the target electronic device may be an electronic device corresponding to the second communication network where the second terminal is located. The dynamic parameters of the second communication network are used for representing the change of the coverage area of the second communication network caused by the position change of the terminal in the second communication network. The position moving track of the second terminal is used for representing the real-time position change of the second terminal.

Step S25, determining a target communication area of the second terminal based on the position movement track and the signal intensity change rate of the second terminal and judging whether there is an overlap between the target communication area and the communication coverage area; if yes, determining a communication interference factor of the second terminal relative to each first terminal based on an overlapping area of the target communication area and the communication coverage area; and determining an adjustment result of at least part of network nodes in the current communication network topological graph according to each communication interference factor and each stability characteristic vector, and performing communication interference resistance adjustment on the first terminals corresponding to the at least part of network nodes based on the adjustment result.

In this embodiment, the communication interference factor is used to represent the interference degree of the second terminal on the communication stability of the first terminal, and the larger the communication interference factor is, the stronger the interference degree of the second terminal on the communication stability of the first terminal is.

In this embodiment, the adjustment result is used to adjust the position and node coverage of at least part of the network nodes in the current communication network topology. The adjustment result can be converted based on the mapping relationship between the network node and the first terminal in the current communication network topological graph to obtain an adjustment instruction for resisting communication interference on the first terminal, and then the adjustment instruction is sent to the first terminal, so that the adjustment of the communication stability of the first terminal is realized.

In this embodiment, the communication stability adjustment for the first terminal may include the following manners, and of course, when implemented in detail, the method is not limited to the following manners.

First, a signal shielding network is generated for a first terminal. For example, the adjustment instruction may be sent to the first terminal, so that the first terminal generates a signal shielding network according to the adjustment instruction, where the signal shielding network may be used to shield a signal frequency band of a second communication network where the second terminal is located. In this way, the first terminal can be ensured from being interfered by the communication of the second terminal.

Second, a buffering period is set for the first terminal. For example, the adjustment instruction may be sent to the first terminal, so that the first terminal performs buffering of a communication behavior when the target communication area and the communication coverage area overlap according to the adjustment instruction, thereby avoiding communication interference of the second terminal when the first terminal performs a normal service, and ensuring stability of the entire first communication network.

In this embodiment, based on steps S21-S25, a first location and a first signal strength of the first communication signal when each first terminal sends the first communication signal can be determined, then a current communication network topology map is generated based on the first location, and a node coverage area corresponding to a network node is obtained by mapping the first signal strength based on the current communication network topology map to determine a communication coverage area of the first communication network. Further, the position moving track of the second terminal is determined based on the detection result of detecting the second communication signal broadcasted by the second terminal, and then the target communication area of the second terminal is determined. Furthermore, a communication interference factor of the second terminal relative to each first terminal is determined based on an overlapping area of the target communication area and the communication coverage area, and anti-communication interference adjustment is performed on the first terminals corresponding to at least part of the network nodes based on the determined stability characteristic vectors corresponding to the network nodes, so that communication interference of the second terminal to the first terminals can be effectively improved, and further communication stability and normal service development of the first terminals are ensured.

It is understood that the communication processing method based on the car networking can be applied to a plurality of fields, such as the field of internet of things, the field of car networking, the field of telemedicine, the field of block chain, the field of automatic control, the field of smart city, the field of e-commerce finance, and the like, and is not limited herein.

In an alternative embodiment, in order to ensure the accuracy of the current communication network topology, it is necessary to take into account the position drift of the first terminal, and for this purpose, in step S22, the generating the current communication network topology according to the first position corresponding to each first terminal may specifically include the following.

Step S221, acquiring a communication address of each first terminal when sending out a corresponding first communication signal, an address offset coefficient corresponding to each communication address, and positioning logic information corresponding to each first terminal; wherein the communication address is an IP address.

Step S225, if the first position falls into the position offset area of the first terminal corresponding to the first position, listing the first position into a preset position list to be processed; wherein the pending position form.

Step S226, if the first location does not fall into the location offset area of the first terminal corresponding to the first location, determining the accumulated working time of the first terminal corresponding to the first location and the breakage rate of the positioning module; determining a position correction coefficient of a first terminal corresponding to the first position based on the accumulated working time and the breakage rate of the positioning module, determining a position correction step length according to the position correction coefficient, and correcting the first position according to the position correction step length to obtain a corrected position; and judging whether the corrected position falls into the position offset area of the first terminal corresponding to the first position, if so, listing the corrected position into the position list to be processed, and if not, correcting the corrected position according to the position correction step length and returning to the step of judging whether the corrected position falls into the position offset area of the first terminal corresponding to the first position.

And step S227, generating a current communication network topological graph according to the first position and the corrected position in the position form to be processed.

In this embodiment, based on steps S221 to S227, the position drift of the first terminals can be taken into consideration, and then it can be determined whether the first position of each first terminal falls into the position offset region corresponding to the first terminal, if so, the first position is represented accurately, and if not, the first position is represented inaccurately. Therefore, the accuracy of the position form to be processed is ensured, and the accuracy of the front communication network topological graph is further ensured.

In a specific implementation, in order to ensure accurate mapping of the communication parameters and the current communication network topology, and further accurately determine the stability feature vector of the network node, in step S23, the determining the communication parameters of each first terminal and mapping the communication parameters of each first terminal to the current communication network topology to obtain the stability feature vector for characterizing the network node corresponding to each first terminal in the current communication network topology may specifically include the following.

In this embodiment, the operation log is used to store all operation data of the first terminal during operation, including but not limited to communication parameters, internal data processing parameters, and the like, and the parameter index is used to characterize the communication parameters in different dimensions, for example, the parameter index may be communication duration, communication period, communication frequency, communication signal category, and the like.

Step S232, performing numerical extraction on the at least one group of parameter indexes to obtain a multidimensional array corresponding to the at least one group of parameter indexes.

Step S233, obtaining a second character matched with the first character of the at least one group of parameter indexes from a preset character database, and merging the second character with the multidimensional arrays corresponding to the at least one group of parameter indexes to generate the first arrays corresponding to the at least one group of parameter indexes.

Step S234, performing feature segmentation processing on the first array corresponding to the at least one group of parameter indexes to obtain a plurality of second arrays corresponding to the at least one group of parameter indexes, adding the plurality of second arrays to the mapping array corresponding to each first terminal, and inputting the mapping array into the mapping thread corresponding to the current communication network topology map to obtain the mapping result of each second array corresponding to each first terminal in the mapping thread; and marking the mapping result of each second array corresponding to each first terminal in the mapping thread based on the node identification of the network node of each first terminal in the current communication network topological graph, and distributing the marked mapping result to the corresponding network node in the current communication network topological graph.

Step S235, obtaining a stability feature vector of each network node according to a plurality of mapping results corresponding to each network node in the current communication network topology map.

It can be understood that, through steps S231 to S235, the parameter index in the communication parameter of the first terminal can be subjected to value extraction and character matching to implement the digitization processing of the parameter index, so that the value in the parameter index, which can reflect the characteristics of the communication parameter, can be extracted and summarized, and the mapping of the communication parameter to the current network topology map is implemented based on the result of the digitization processing. Therefore, accurate mapping of the communication parameters and the current communication network topological graph is ensured, and the stability characteristic vector of the network node is further accurately determined.

In practical applications, the accuracy of the value extraction is a key to ensure accurate mapping between the communication parameters and the current communication network topology, and for this reason, in step S232, the value extraction is performed on the at least one group of parameter indexes to obtain the multidimensional array corresponding to the at least one group of parameter indexes, which may specifically include the following contents.

Step S2321, when it is determined that the at least one set of parameter indexes includes an access request identifier for accessing the electronic device, acquiring, according to the access request identifier included in the at least one set of parameter indexes and used for accessing the electronic device, first state data of the at least one set of parameter indexes in a data request state on at least one communication record from the at least one communication record establishing an access link with the electronic device.

Step S2322, according to the weight of the access request identifier in the at least one group of parameter indexes, a target value extraction rule corresponding to the access request identifier is searched in a value extraction rule set preset in the electronic device, where the target value extraction rule is used to instruct the electronic device to perform value extraction on the at least one group of parameter indexes.

It can be understood that the accuracy of numerical value extraction can be ensured by the method, and further the accurate mapping of the communication parameters and the current communication network topological graph is ensured.

In a specific implementation, in order to ensure the accuracy of the communication interference factor, in step S25, the determining the communication interference factor of the second terminal with respect to each first terminal based on the overlapping area of the target communication area and the communication coverage area may specifically include the following steps.

It can be understood that, through the above, the communication operating states of the first terminal and the second terminal when the target communication area overlaps with the communication coverage area can be analyzed, and then the communication interference factor of the second terminal relative to each first terminal is determined, so that the communication interference factor can be accurately determined.

In practical applications, in step S25, the determining, according to each communication interference factor and each stability feature vector, an adjustment result of at least part of network nodes in the current communication network topology map and performing, based on the adjustment result, communication interference resistance adjustment on the first terminal corresponding to the at least part of network nodes may specifically include the following.

Based on the above, it can be understood that the packet loss rate and the delay of the first terminal can be used as the basis for determining the communication stability, so that whether the first terminal receives the communication interference of the second terminal can be accurately determined, and then the adjustment result can be accurately determined to realize the adjustment of the first terminal against the communication interference.

On the basis of the above, the adjusting result is sent to the first terminal corresponding to each perturbation node, so that the first terminal corresponding to each perturbation node performs communication interference resistance adjustment according to the adjusting result, which may specifically include the following contents.
