In order to solve the problem that communication bandwidth is crowded in a communication technology realized based on 5G and edge computing, the disclosure discloses a network processing method based on 5G and edge computing and a cloud communication network server, which can divide a communication network of the whole production environment into a plurality of non-interfering sub-networks according to the link centrality between different equipment terminals, so as to realize a cluster type industrial interconnection network in which each sub-network operates independently. Therefore, the traffic in the sub-network can be shunted, and the congestion of the communication bandwidth caused by overlarge data traffic carried in a certain period of time is improved.

Please refer to fig. 1, which is a schematic flow chart of a network processing method based on 5G and edge computing according to the present disclosure, the method may be applied to a cloud communication network server, the cloud communication network server communicates with n device terminals (n is a positive integer), the n device terminals communicate with each other to form an industrial internet, and the industrial internet may be applied to different production environments, such as smart manufacturing. Further, the method may specifically include the contents described in the following steps S100 to S600.

Step S100, acquiring a request instruction triggered by at least one first device terminal in the n device terminals and used for switching production conditions, and obtaining the link centrality of the at least one first device terminal in a networking record according to the request instruction of the at least one first device terminal and the networking record of the at least one first device terminal recorded by the cloud communication network server; the networking records are stored in a database of the cloud communication network server and used for recording a communication log of each equipment terminal, and the link centrality is used for representing the proportion of the accumulated number m and the n of links existing between the first equipment terminal and other equipment terminals in each networking process.

It can be understood that the larger the ratio of m to n, the higher the link centrality of the first device terminal, indicating that the greater the number of device terminals linked to the first device terminal, where n and m are positive integers in this embodiment.

Step S200, calculating the switching time consumption required by the at least one first equipment terminal when the networking state is switched according to the request instruction through the time period information of the networking record corresponding to the link centrality; the networking state switching is used for representing the sum of time consumed for disconnecting an old link and establishing a new link when the at least one first equipment terminal conducts the networking state switching.

Step S300, according to the sequence of the switching time consumption from small to large, sequentially taking a topology node of the at least one first equipment terminal in a first network topology formed by the n equipment terminals as a reference, constructing a communication sub-network of the first equipment terminal corresponding to the minimum switching time consumption according to the request instruction, and setting a communication frequency band for each communication sub-network based on the calculated communication interference coefficient between a second network topology corresponding to each communication sub-network and the first network topology; wherein the communication frequency bands between different communication subnets are different.

Step S400, determining whether each two communication subnets in the constructed communication subnets have the same target topology node.

Step S500, in a case that the same topology node exists in each of the two communication subnets, removing the target topology node from the communication subnet with a smaller communication interference coefficient in each of the two communication subnets, and returning to the step of determining whether the same target topology node exists in each of the two communication subnets in the constructed communication subnets.

Step S600, in the case that the same topology node does not exist in each of the two communication subnets, generating a configuration instruction according to the constructed distribution information of the communication subnets, and issuing the configuration instruction to each device terminal.

When the contents described in the above steps S100 to S600 are applied, the link centrality of the first device terminal is first calculated when the request instruction is obtained, then the switching time consumption of the first device terminal is calculated based on the link centrality, then the communication subnets of each first device terminal are sequentially constructed and the non-interfering communication frequency bands are allocated based on the sequence of the switching time consumption from small to large, and whether the same target topology node exists in each two communication subnets in the constructed communication subnets is further determined, and the subnet adjustment of the device terminal is performed according to the determination result.

Therefore, the communication network of the whole production environment can be divided into a plurality of non-interfering sub-networks according to the link centrality between different equipment terminals, and the clustered industrial interconnection network with each sub-network operating independently is realized. Therefore, the traffic in the sub-network can be shunted, and the congestion of the communication bandwidth caused by overlarge data traffic carried in a certain period of time is improved.

In practical application, the inventor finds that the occupancy rates of the communication bandwidths of different communication subnets are different in the same period, and for some communication subnets, the data traffic processed in some periods may be more, and there may still be a case that the communication bandwidths are overloaded. To improve the above problem, on the premise of the above step S100 to step S600, the cloud communication network server may further perform the following steps S710 to step S730.

Step S710, monitoring the communication bandwidth occupancy rate of each communication subnet in real time, and if the first communication bandwidth occupancy rate of a first target communication subnet is monitored to reach a set threshold, determining a second target communication subnet from the communication subnets according to a first difference value between the first communication bandwidth occupancy rate and the set threshold; and a second difference between the second communication bandwidth occupancy rate of the second target communication subnet and the set threshold meets a set condition.

In step S710, the setting condition may be that the second difference is equal to or greater than the first difference. For example, the first difference is x, then the second difference is y, and y > x. Therefore, the second target communication subnet can be ensured to adjust the communication frequency band on the premise of ensuring the data traffic processing of the second target communication subnet, so that the first target communication subnet is provided with the assistance and the support of the communication frequency band, and the condition of the overload of the communication bandwidth of the first target communication subnet is improved.

Step S720, adjusting the second communication frequency band corresponding to the second target communication subnet based on the second communication broadband occupancy of the second target communication subnet, so as to obtain the frequency band resource packet generated by adjusting the second communication frequency band.

Step S730, mapping the frequency band description information in the frequency band resource packet to a first communication frequency band corresponding to the first target communication subnet, obtaining a target frequency band interval of the frequency band description information in the first communication frequency band, and adjusting the first communication frequency band according to the target frequency band interval.

In step S730, the range of the first communication band may be expanded based on the target band section, which can reduce the load of the communication bandwidth of the first target communication subnet. Thereby avoiding congestion of the first target communication sub-network.

Based on the steps S710 to S730, each communication subnet can be monitored, so that when the communication bandwidth of the communication subnet is overloaded, the load of the communication bandwidth can be adjusted by using the frequency band allocation of other communication subnets, thereby avoiding congestion of the communication subnet during operation.

In a possible embodiment, when calculating the switching time consumption of the first device terminal, the time delay and configuration parameter adjustment of the first device terminal when performing the networking state switching need to be considered, so that the switching time consumption of the first device terminal can be accurately and reliably determined. To achieve the above object, the calculating, by the time period information of the networking record corresponding to the link centrality, described in step S200, a switching time consumption required by the at least one first device terminal when performing networking state switching according to the request instruction may specifically include the contents described in steps S210 to S240.

Step S210, finding out an information tag corresponding to the time interval information from the networking record corresponding to the link centrality, and generating a first information set corresponding to the networking record according to the information tag; generating a second information set corresponding to the link centrality based on the corresponding relation between the link centrality and the updating frequency of the networking record corresponding to the link centrality; the first information set is used for representing the time period characteristics of the networking records, the second information set is used for representing the validity characteristics of the networking records, and the first information set and the second information set respectively comprise a plurality of information nodes with different relevance degrees.

Step S220, determining a first information node with the maximum association degree in the first information set and a second information node with the minimum association degree in the second information set, and constructing an association logic list of the first information set and the second information set according to first position information of the first information node in the first information set and second position information of the second information node in the second information set; wherein the logical list of associations is used to characterize a degree of information fusion between the first set of information and the second set of information.

Step S230, extracting a first target thread parameter and a second target thread parameter from the state switching thread of the at least one first device terminal based on the relevance logic list; the state switching thread is started by the at least one first device terminal when the networking state is switched according to the request instruction, the first target thread parameter is used for representing a delay parameter of the at least one first device terminal when the networking state is switched, and the second target thread parameter is used for representing a configuration parameter change parameter of the at least one first device parameter when the networking state is switched.

Step S240, intercepting multiple sets of third target thread parameters of the second target thread parameter in a set time period according to a set step length, calculating a delay weight of the delay parameter relative to each set of third target thread parameters, weighting a delay time value corresponding to the delay parameter by using the delay weight to obtain a weighted sum value, calculating an adjustment time-consuming time value of a configuration parameter of the at least one first device terminal according to a similarity of adjacent third target thread parameters, and adding the weighted sum value and the adjustment time-consuming time value to obtain switching time-consuming time required by the at least one first device terminal when performing networking state switching according to the request instruction.

It can be understood that, when the contents described in steps S210 to S240 above are applied, when calculating the time consumption for switching the first device terminal, the time delay corresponding to the switching of the networking state of the first device terminal and the time consumption corresponding to the adjustment of the configuration parameter can be considered. Thus, the time consumed for switching the first equipment terminal can be accurately and reliably determined.

In a possible example, in order to accurately determine the communication subnet of each first device terminal, the constructing of the communication subnet of the first device terminal corresponding to the minimum handover time consumption according to the request instruction described in step S300 may specifically include the following contents described in steps S310 to S330.

Step S310, parsing the request instruction to obtain connection direction information, included in the request instruction, of the first device terminal corresponding to the minimum switching time.

Step S320, determining a plurality of second device terminals corresponding to the first device terminal corresponding to the minimum switching time consumption according to the connection direction information.

Step S330, aiming at each second equipment terminal, judging whether the link centrality of the second equipment terminal is less than or equal to the link centrality of the first equipment terminal corresponding to the minimum switching time consumption; and if so, adding a first terminal identifier of the first equipment terminal and a second terminal identifier of the second equipment terminal corresponding to the minimum switching time consumption into a preset identifier group, and constructing a communication subnet of the first equipment terminal corresponding to the minimum switching time consumption according to the first terminal identifier and the second terminal identifier in the identifier group.

Based on the above steps S310 to S330, the link centrality of the first device terminal and the second device terminal can be taken into account when the communication subnet is established, so as to avoid that the communication subnet is still established with the first device terminal as the subnet center when the link centrality of the second device terminal is greater than the link centrality of the first device terminal. In this way, the communication subnet of each first device terminal can be accurately determined.

In a specific embodiment, the communication interference coefficient in step S300 can be obtained through the following steps (1) - (3).

(1) And respectively constructing a first network coverage area of the first network topology and a second network coverage area of the second network topology by using communication addresses of topology nodes in the first network topology and the second network topology.

(2) Determining an overlapping area of the first network coverage area and the second network coverage area.

(3) And determining an interference factor between the second network topology and the first network topology according to the number of network coverage areas corresponding to the overlapping areas, and correcting a preset initial interference factor based on the interference factor to obtain the communication interference factor.

Through the steps (1) to (3), the communication interference coefficient can be accurately determined based on the overlapping condition of the network coverage area.

The inventor finds that in practical application, the number and types of the device terminals in different communication subnets are different, and if a uniform configuration instruction generation mode is adopted to generate the configuration instruction, some device terminals in the communication subnets cannot be compatible with the configuration instruction when the configuration instruction is issued. To improve the above technical problem, the generation of the configuration instruction according to the distribution information of the constructed communication subnet described in step S600 may specifically include the contents described in the following steps S610 to S650.

Step S610, extracting the communication priority of each target device terminal in each communication sub-network and the dynamic check code of each target device terminal in the protocol layer of the corresponding communication priority; the communication priority is used for representing the information transceiving rate of each target device terminal in the corresponding communication subnet, the protocol layer is used for indicating the encapsulation logic of the protocol field of the corresponding target device terminal during information transceiving, and the dynamic check code is used for representing the check type of the encapsulation logic.

Step S620, the target device terminals in each communication subnet are sorted according to the descending order of the communication priority to obtain a first sorting sequence, and the target device terminals in each communication subnet are sorted according to the descending order of the check passing rate of the target device terminals determined based on the dynamic check code to obtain a second sorting sequence.

Step S630, for each target device terminal in each communication subnet, determining whether a first sorting position of the target device terminal in the corresponding first sorting sequence is the same as a second sorting position of the target device terminal in the corresponding second sorting sequence; if the terminal type information is the same as the terminal type information, adding a first signature to the terminal type information corresponding to the target equipment terminal; if not, calculating whether the difference value between a first sequence number value corresponding to a first sequencing position corresponding to the target equipment terminal and a second sequence number value corresponding to a second sequencing position corresponding to the target equipment terminal is lower than a preset threshold value; if so, adding a second signature to the terminal type information corresponding to the target equipment terminal; and if not, adding a third signature to the terminal type information corresponding to the target equipment terminal.

In this embodiment, the first signature is used to characterize that the target terminal device supports instruction compatibility, the second signature is used to characterize that the target terminal device supports partial instruction compatibility, and the third signature is used to characterize that the target terminal device does not support instruction compatibility.

Step 640, determining a command heterogeneous coefficient corresponding to each communication subnet based on the class proportion information of the signature added to the terminal type information corresponding to each target device terminal in each communication subnet and the number of the target device terminals in each communication subnet; the instruction heterogeneous coefficient is used for representing the heterogeneity of the initial configuration instruction corresponding to each target device terminal in the communication sub-network.

Step S650, generating an initial configuration instruction corresponding to each target device terminal according to the signature type corresponding to the target device terminal in each communication subnet; and coding each initial configuration instruction according to the heterogeneous corresponding value of the instruction heterogeneous coefficient in each initial configuration instruction to obtain a configuration instruction corresponding to each communication subnet.

It is understood that through the descriptions of the above steps S610 to S650, the number and types of the device terminals in the communication subnet can be analyzed, so as to determine the signature of the terminal type information of the target device terminal based on the ordered sequence of the target device terminal on the communication priority and dynamic check code level. Therefore, the generated initial configuration instruction of each target device terminal can be coded according to the signature type and the number of the target device terminals in the communication sub-network, so that the configuration instruction corresponding to each communication sub-network is obtained, and the situation that some device terminals in the communication sub-network cannot be compatible with the configuration instruction when the configuration instruction is issued is avoided.

In an alternative embodiment, the setting of the communication frequency band for each communication subnet based on the calculated communication interference coefficient between the second network topology and the first network topology corresponding to each communication subnet described in step S300 may specifically include the following steps a to c.

Step a, carrying out normalization processing on the communication interference coefficient corresponding to each communication subnet obtained by calculation to obtain a target coefficient corresponding to each communication subnet; wherein the target coefficient is a value greater than zero and less than one.

B, searching frequency band information corresponding to each target coefficient in a preset frequency band distribution list; and the frequency band information is used for representing the frequency band selection range of the communication subnet.

C, determining a target frequency band from a frequency band selection range corresponding to each communication subnet as the communication frequency band of each communication subnet according to the network polymerization degree of the second network topology of each communication subnet; and the network polymerization degree is obtained according to a node characteristic information set corresponding to the second network topology, and the node characteristic information set is extracted by a k-means clustering method.

When the content described in the above steps a to c is applied, an accurate communication frequency band can be allocated and set for each communication subnet, and communication interference caused by intersection and overlapping of the communication frequency bands between the communication subnets is avoided.
