Description

Technical Field

[0001] The present invention relates to the field of data transmission technology, and in particular to a 5G-based communication terminal switching system. Background Art

[0002] Communication terminal switching is usually implemented through network switching devices, which are responsible for connecting terminal devices and forwarding data packets to the target terminal device based on the destination address of the data and the network topology.

[0003] However, in traditional communication terminal switching systems, bandwidth is limited, especially for large-scale data transmission and applications with high bandwidth requirements. This may lead to slow data transmission speed and high latency, affecting communication quality and user experience. At the same time, data transmission in the communication terminal switching system may have security risks, such as data leakage and illegal access. Traditional communication terminal switching systems lack a strong security mechanism and cannot effectively protect the confidentiality and integrity of data. How to improve the efficiency and security of the data process between communication terminals is an important issue at present. To this end, a 5G-based communication terminal switching system is provided. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a 5G-based communication terminal switching system.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A 5G-based communication terminal switching system includes a control center, wherein the control center is communicatively connected to a communication terminal information collection module, a transmission channel management module, a terminal switching module, and a data detection module;

[0007] The communication terminal information collection module is used to collect various basic data of the communication terminal, and then establish a communication terminal information set corresponding to the communication terminal, and at the same time integrate all the communication terminal information sets to obtain a communication terminal information library;

[0008] The transmission channel management module is used to collect the number of transmission channels and bandwidth information of each communication terminal to establish an electronic diagram of the transmission channels;

[0009] The terminal exchange module is used to send a data detection task to the data detection module according to the data exchange request and exchange data of the communication terminal, and at the same time obtain the current state of the transmission channel of the corresponding communication terminal from the transmission channel electronic diagram and establish a data exchange strategy, so that the communication terminal completes the data exchange according to the data exchange strategy;

[0010] The data detection module is used to execute data detection tasks, and then perform security detection and data type conversion on the exchanged data according to the communication terminal data set.

[0011] Furthermore, the process of establishing the communication terminal information database includes:

[0012] Each communication terminal sends location information to the communication terminal information collection module, where the location information includes the IP address and geographical location of the corresponding communication terminal;

[0013] The communication terminal information collection module sends a location response to the corresponding communication terminal according to the received location information. If the corresponding communication terminal returns a location response, the communication terminal information collection module records the location information of the corresponding communication terminal and sets a number for it, otherwise deletes the location information of the corresponding communication terminal;

[0014] The communication terminal information acquisition module sends a terminal information acquisition request to each communication terminal. After receiving the terminal information acquisition request, the communication terminal sends the terminal information to the communication terminal information acquisition module, wherein the terminal information includes the number and bandwidth of the transmission channel corresponding to the communication terminal and the communication protocol;

[0015] Then, the communication terminal information collection module establishes a communication terminal information set according to the location information and terminal information of each communication terminal, and integrates the communication terminal information sets of all communication terminals to obtain a communication terminal information database.

[0016] Furthermore, the process of establishing the transmission channel electronic diagram includes:

[0017] The geographical location, number of transmission channels and corresponding bandwidth of each communication terminal are extracted from the communication terminal information database, and the transmission channel management module establishes an electronic map of the transmission channels according to the geographical location of the roadside unit to which the edge terminal is connected.

[0018] Furthermore, in the electronic map of transmission channels, each communication terminal is proportionally mapped on the electronic map of transmission channels according to its actual geographical location, and each communication terminal is marked with a corresponding number, IP address, number of transmission channels, and current status of each transmission channel.

[0019] Furthermore, the data detection task process generated by the terminal exchange module according to the data exchange request includes:

[0020] The communication terminal sends a data exchange request to the terminal exchange module, wherein the data exchange request includes the IP address of the communication terminal sending the data exchange request and the IP address of the communication terminal receiving the data exchange request. According to the IP addresses of each communication terminal in the data exchange request, the edge terminal sends the data exchange request to the communication terminal of the recipient;

[0021] If the communication terminal of the receiving party does not agree with the data exchange request, the terminal exchange module rejects the data exchange request. If the communication terminal of the receiving party does not agree with the data exchange request, the terminal exchange module sends a request approval prompt to the communication terminal that sent the data exchange request.

[0022] When the communication terminal receives the prompt that the request is passed, it generates a data detection task according to the exchange data to be sent and sends it to the data detection module, wherein the data detection task includes the exchange data and the IP addresses of each communication terminal performing data exchange.

[0023] Furthermore, the process of generating a data exchange strategy by the terminal exchange module includes:

[0024] The data exchange strategy is divided into a first data exchange strategy and a second data exchange strategy. First, the terminal exchange module determines whether there is an idle transmission channel at the communication terminal of the sender. If so, a primary data transmission channel for data exchange is randomly selected from the idle transmission channels.

[0025] Setting a data transmission deadline, and then judging whether the data transmission can be completed within the data transmission deadline according to the bandwidth of the primary data transmission channel and the size of the exchanged data, and generating a first data exchange decision according to the judgment result;

[0026] If it does not exist, the exchange data transmission is completed within the data transmission deadline, and according to the amount of data that can be transmitted by the main data transmission channel within the data transmission deadline, the exchange data segments of equal length are cut out from the exchange data according to the amount of data, and at the same time, the terminal exchange module searches for the transmission channel to be overflowed from the sending communication terminal, and obtains its current remaining bandwidth, and then obtains the total amount of data that can be transmitted by the current remaining bandwidth of each transmission channel to be overflowed within the data transmission deadline, compares the total amount of data with the amount of data of the remaining exchange data segments, and generates a first data exchange decision according to the comparison result;

[0027] At the same time, the second data exchange decision is generated using the same method as the first data exchange decision.

[0028] Furthermore, the process of the communication terminal performing data exchange according to the data exchange strategy includes:

[0029] The terminal exchange module sends the first data exchange decision to the communication terminal of the sender and sends the second data exchange decision to the communication terminal of the receiver. Then the communication terminals complete the data exchange according to their respective received data exchange strategies and send a data exchange completion prompt to the terminal exchange module.

[0030] Furthermore, the process of the data detection module performing the data detection task includes:

[0031] The data detection module extracts the exchange data from the data detection module, and at the same time, the data detection module obtains several dangerous data samples through the Internet, and extracts several dangerous data feature points from the dangerous data samples, and then matches the exchange data through the dangerous data feature points;

[0032] Set a quantity threshold. If the number of matching feature points between the exchanged data and the dangerous data is greater than or equal to the quantity threshold, the corresponding exchanged data is judged to be dangerous data. At the same time, the data detection module sends a dangerous data warning to the terminal exchange module, and then the terminal exchange module will stop the corresponding data exchange process;

[0033] If the number of matching feature points between the exchange data and the dangerous data is less than the quantity threshold, the data detection module converts the exchange data into an exchange of the corresponding data type according to the communication terminal information set and sends it to the terminal exchange module.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] The present invention collects various basic data of communication terminals, and then establishes a communication terminal information set corresponding to the communication terminal, and at the same time integrates all communication terminal information sets to obtain a communication terminal information base, collects the number of transmission channels and bandwidth information of each communication terminal, and then establishes a transmission channel electronic map, thereby improving the management efficiency of transmission resources of the communication terminal, generating data detection tasks according to data exchange requests and exchanged data of the communication terminal, performing security detection and data type conversion on the exchanged data according to the data detection tasks and the communication terminal data set, thereby ensuring the security of the system and the flexibility of transmission during the data exchange process, and at the same time obtaining the current state of the transmission channel of the corresponding communication terminal from the transmission channel electronic map and establishing a data exchange strategy, and then the communication terminal completes the exchange according to the data exchange strategy; the present invention improves the data exchange efficiency and security between communication terminals.

[0038] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0039] like Figure 1 As shown, a 5G-based communication terminal switching system includes a control center, and the control center is communicatively connected to a communication terminal information collection module, a transmission channel management module, a terminal switching module, and a data detection module;

[0040] The communication terminal information acquisition module is used to obtain information of each communication terminal, and then establish a communication terminal information database according to the information of each communication terminal. The specific process includes:

[0041] Each communication terminal sends location information to the communication terminal information collection module, where the location information includes the IP address and geographical location of the corresponding communication terminal;

[0042] The communication terminal information collection module sends a location response to the corresponding communication terminal according to the received location information. If the corresponding communication terminal returns a location response, the communication terminal information collection module records the location information of the corresponding communication terminal and sets a number for it. For example, the number can be s1, s2, s3, ..., s n , where n is a natural number greater than 0, otherwise the location information of the corresponding communication terminal is deleted;

[0043] Further, the communication terminal information acquisition module sends a terminal information acquisition request to each communication terminal, and after receiving the terminal information acquisition request, the communication terminal sends terminal information to the communication terminal information acquisition module, wherein the terminal information includes the number and bandwidth of the transmission channel corresponding to the communication terminal and the communication protocol;

[0044] Then, the communication terminal information collection module establishes a communication terminal information set S according to the location information and terminal information of each communication terminal, wherein the communication terminal information set S can be expressed as:

[0045] S i ={Add i 、Loca i ,(Num1,Band1),...,(Num m , Band m ), Word i};

[0046] Where S i 、Add i 、Locai 、(Num m , Band m ), Word i Respectively represent the number s i The communication terminal information set, IP address, geographic location, mth transmission channel and corresponding bandwidth and communication protocol of the communication terminal, i, m are natural numbers greater than 0, and i≤n;

[0047] The communication terminal information sets S of all communication terminals are integrated to obtain a communication terminal information database. It should be noted that when the communication terminal information collection module receives new communication terminal information, it automatically generates a communication terminal information set based on the communication terminal information and updates the communication terminal information database.

[0048] The transmission channel management module is used to manage the transmission channel of each communication terminal according to the communication terminal information set in the communication terminal information database, and the specific process includes:

[0049] After the communication terminal information collection module establishes the communication terminal information database, it sends prompt information to the transmission channel management module, and then the transmission channel management module communicates with the communication terminal information database and extracts all communication terminal information sets from the communication terminal information database;

[0050] The transmission channel management module is communicatively connected to a plurality of edge terminals, and the edge terminals are numbered H1, H2, ..., H i , i is a natural number greater than 0, where each edge terminal is connected to multiple roadside units and is numbered h 1,1 ,……,h i,j ,h i,j Indicates the number is H i The j-th roadside unit of the connection point of the communication terminal, and each roadside unit is provided with the same number of transmission channels with the same bandwidth;

[0051] The transmission channel management module extracts the geographical location, number of transmission channels and corresponding bandwidth of each communication terminal from the communication terminal information database, and at the same time, the transmission channel management module establishes an electronic diagram of the transmission channels according to the geographical location of the roadside unit to which the edge terminal is connected;

[0052] In the transmission channel electronic map, each communication terminal and roadside unit is mapped on the transmission channel electronic map in proportion according to its actual geographical location, and each communication terminal is marked with a corresponding number, IP address, number of its transmission channels and the current state of each transmission channel, and the roadside unit is marked with a corresponding number, number of transmission channels and the current state of each transmission channel;

[0053] Then the transmission channel management module sends the transmission channel electronic diagram to the data detection module and the terminal interaction module.

[0054] The terminal exchange module is used to manage the data exchange process between various communication terminals. The specific process includes:

[0055] The communication terminal sends a data exchange request to the terminal exchange module, wherein the data exchange request includes the IP address of the communication terminal sending the data exchange request and the IP address of the communication terminal receiving the data exchange request. It should be noted that the communication terminal receiving the data exchange request may have multiple IP addresses at the same time;

[0056] According to the IP address of each communication terminal in the data exchange request, the terminal exchange module searches for the corresponding communication terminal from the transmission channel electronic diagram from the transmission channel management module, and then the terminal exchange module sends the data exchange request to the edge terminal closest to the communication terminal receiving the data exchange request, and the edge terminal sends the data exchange request to the roadside unit, and the roadside unit sends it to the communication terminal;

[0057] If the corresponding communication terminal does not agree to the data exchange request, the terminal exchange module rejects the data exchange request;

[0058] If the corresponding communication terminal does not agree to the data exchange request, the terminal exchange module sends a request approval prompt to the communication terminal that sent the data exchange request;

[0059] Further, when the communication terminal receives the prompt of the request passing, a data detection task is generated according to the exchange data to be sent and sent to the data detection module, wherein the data detection task includes the exchange data and the IP address of each communication terminal performing the data exchange;

[0060] The data detection module converts the exchange data into exchange data of the corresponding data format according to the data detection task and the communication protocol of the communication terminal of the receiving party, and sends it to the terminal exchange module;

[0061] After receiving the converted exchange data, the terminal exchange module traverses to obtain the data size, and at the same time obtains the real-time status of the transmission channel of the communication terminal performing data exchange from the transmission channel electronic diagram;

[0062] It should be noted that the transmission channel has an idle state, an overflow state and a non-overflow state, wherein the idle state indicates that the corresponding transmission channel does not transmit any data, the overflow state indicates that the bandwidth of the corresponding transmission channel is fully used, and the to-be-overflow state indicates that the corresponding transmission channel is in a data transmission state and its bandwidth is not fully used;

[0063] The terminal exchange module generates a data exchange strategy according to the data size of the exchanged data and the real-time status of the transmission channel of the communication terminal performing the data exchange, wherein the data exchange strategy is divided into a first data exchange strategy and a second data exchange strategy;

[0064] The data exchange strategy generation process includes:

[0065] First, the terminal exchange module determines whether there is an idle transmission channel at the communication terminal of the sender. If so, a primary data transmission channel is randomly selected from the idle transmission channels as the primary data transmission channel for data exchange.

[0066] Set a data transmission deadline, and then determine whether the exchange data transmission can be completed within the data transmission deadline according to the bandwidth of the main data transmission channel and the size of the exchanged data;

[0067] If it is determined that the exchange data transmission can be completed within the data transmission deadline, the number of the primary data transmission channel is recorded, and a first data exchange decision is generated;

[0068] If it is determined that the exchange data transmission cannot be completed within the data transmission deadline, then according to the amount of data that can be transmitted by the main data transmission channel within the data transmission deadline, the exchange data fragments of equal length are cut out from the exchange data according to the data amount, and at the same time, the terminal exchange module searches for the transmission channel in the to-be-full state from the sending communication terminal, and obtains its current remaining bandwidth, and then obtains the total amount of data that can be transmitted by the current remaining bandwidth of each transmission channel in the to-be-full state within the data transmission deadline;

[0069] If the total amount of data is greater than or equal to the amount of data of the remaining exchange data fragments, then according to the amount of data of each transmission channel at the data transmission deadline, the remaining exchange data fragments are divided into exchange data fragments of corresponding numbers and data sizes, and the numbers of the transmission channels to be overflowed are recorded to generate a data sequence message, and then a first data exchange strategy is generated, wherein the data sequence message is composed of the exchange data fragments divided by the remaining exchange data fragments, and the numbers of the corresponding transmission channels are arranged in the same order when data is transmitted in sequence;

[0070] If the total amount of data is less than the amount of data of the remaining exchanged data fragments, the exchange terminal module searches for a roadside unit close to the communication terminal of the sender according to the transmission channel electronic diagram, and then obtains the amount of data that can be transmitted within the data transmission deadline according to the bandwidth of the transmission channel in the roadside unit, and then selects a corresponding number of transmission channels from the roadside unit by rounding up according to the difference between the total amount of data and the amount of data of the remaining exchanged data fragments, and generates a data sequence message according to the transmission channel number of the selected communication terminal and the number of the roadside unit, and generates a first data exchange decision;

[0071] If the communication terminal currently does not have a transmission channel in an idle state, the method of counting the transmission channels in the overflow state and selecting the roadside unit is used to generate a data sequence message and a first data exchange decision;

[0072] Similarly, according to the method for obtaining the first data exchange decision, statistics are collected on the current transmission channel of the communication terminal of the receiver, thereby generating a second data exchange decision;

[0073] The terminal exchange module sends the first data exchange decision to the communication terminal of the sender, and sends the second data exchange decision to the communication terminal of the receiver;

[0074] Then, the communication terminals performing data exchange complete the data exchange according to the data exchange strategies they receive, and send a data exchange completion prompt to the terminal exchange module.

[0075] The data detection module is used to complete the data detection task from the terminal switching module, and the specific process includes:

[0076] After receiving the data detection task, the data detection module searches for the communication terminal information set of the communication terminal with the corresponding number from the communication terminal database according to the number of the communication terminal in the data detection task;

[0077] Then the data detection module extracts the exchange data from the data detection module, and at the same time the data detection module obtains several dangerous data samples through the Internet, and extracts several dangerous data feature points from the dangerous data samples, and then matches the exchange data through the dangerous data feature points;

[0078] A quantity threshold P is set. If the number of matching feature points between the exchanged data and the dangerous data is greater than or equal to the quantity threshold P, the corresponding exchanged data is judged to be dangerous data. At the same time, the data detection module sends a dangerous data warning to the terminal exchange module, and then the terminal exchange module stops the corresponding data exchange process;

[0079] If the number of matches between the exchange data and the dangerous data feature points is less than the quantity threshold P, the data detection module extracts the communication protocol Word from the communication terminal information set, and then converts the exchange data into an exchange of the corresponding data type according to the communication protocol Word and sends it to the terminal exchange module.

[0080] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
