According to the network switching method, the network equipment is used for acquiring the communication quality conditions of the first communication link corresponding to the first operator network when the communication is performed, wherein the communication quality conditions comprise communication delay conditions and/or communication packet loss conditions, when the communication quality conditions do not meet preset communication conditions, the network equipment is switched to the second communication link corresponding to the second operator network to perform communication, so that when the communication quality is poor, the automatic switching of the operator network can be performed in time, the stability of network communication is guaranteed, and the efficiency is higher.
Referring to fig. 1, fig. 1 is a flowchart of a network switching method according to an embodiment of the present application, where the method includes the following steps:
step S110: and acquiring the communication quality condition of a first communication link corresponding to the first operator network when the first communication link is used for communication.
The network switching method is applied to network equipment, wherein the network equipment is equipment for providing network services and can convert network signals (such as 3G, 4G or 5G signals) of an operator network into wireless signals. In a 5G application scenario, the network device may be a 5G router.
The operator may include mobile, corporate, radio and telecommunications, so the operator network may then include four of a mobile network, a corporate network, a radio network and a telecommunications network, wherein the first operator network or the second operator network may be any of these four depending on the operator of the subscriber identity card (Subscriber Identity Module, SIM) card inserted on the network device. Therefore, the network device may provide up to four communication links to communicate with the network server.
The network device may support at least two operator networks, for example, the network device may have at least two SIM card slots, which may be used to insert at least two internet of things cards of different operators, respectively, where slot 1 may default to a primary dial-up link, and slot 2 may default to a backup dial-up link, and typically, use the primary dial-up link to communicate as preferentially as possible. Of course, the primary dial-up link and the standby dial-up link may be backup links, and of course, if the network device may be plugged into four internet of things cards, four communication links may be improved, and at this time, the four communication links may be backup links. The network device can be respectively connected to two operator networks in a dialing mode, communication connection is established between the network device and a network server (the network server can be an L2TP network server, for example), various server resources of an enterprise internal office network and a production network can be accessed after the authentication passes, and the overall network architecture can be shown as a figure 2.
It may be understood that the first communication link in the embodiments of the present application may refer to one of the communication links, such as a main dial-up link, if the slot 1 is inserted into an internet of things network card of a mobile operator, the first operator network is a mobile network, and if the slot 2 is inserted into a physical network card of a telecom operator, the second operator network is a telecom network.
In order to ensure communication stability, the network device may detect, in real time or periodically, a communication quality condition of the first communication link of the current communication, where the communication quality condition includes a communication delay condition and/or a communication packet loss condition, and if the communication delay is large and/or the communication packet loss is serious, consider that the communication quality is bad, and the first communication link of the current communication is unstable and cannot ensure the communication quality, so that whether to switch the network may be determined according to the communication delay condition and/or the communication packet loss condition.
Step S120: and when the communication quality condition does not meet the preset communication condition, switching to a second communication link corresponding to the second operator network for communication.
After the communication quality condition is obtained, whether the communication quality condition meets a preset communication condition or not can be judged, wherein the preset communication condition refers to a communication condition when the communication quality is good, if the communication quality condition does not meet the preset communication condition, the network can be switched to a second operator network, and then a second communication link corresponding to the second operator network is adopted for communication.
In the implementation process, by acquiring the communication quality condition of the first communication link corresponding to the first operator network during communication, the communication quality condition comprises a communication delay condition and/or a communication packet loss condition, and when the communication quality condition does not meet the preset communication condition, the communication is switched to the second communication link corresponding to the second operator network for communication, so that when the communication quality is poor, the automatic switching of the operator network can be performed in time, the stability of network communication is ensured, and the efficiency is higher.
On the basis of the above-described embodiment, whether or not the communication quality condition satisfies the preset communication condition can be judged by: receiving a reply message fed back by the network server aiming at the detection message sent by the network equipment, counting communication parameters corresponding to the reply message, and judging whether the communication quality condition meets preset communication conditions according to the communication parameters.
The network device may send the probe packet to the network server in real time or periodically, and when sending the probe packet, may use an IP address of a network interface (e.g., a 5G interface of a 5G router) on the network device as a source address, and an IP address of a physical interface of the network server as a destination IP address, so as to package the probe packet. After receiving the detection message, the network server needs to respond to the detection message, that is, feeds back a reply message to the network device, wherein the reply message uses the IP address of the physical interface of the network server as a source IP address and uses the IP address of the network interface of the network device as a destination IP address. After the network device receives the reply message, the communication parameters of the reply message can be counted, and the communication parameters can represent the communication quality of the communication between the network device and the network server, so that whether the communication quality condition meets the preset communication condition can be judged according to the communication parameters.
In the implementation process, the communication quality condition is judged by counting the communication parameters of the reply message, so that the actual communication condition of the link can be considered, and the communication quality condition of the link can be more accurately judged.
Based on the above embodiment, the communication parameters may include a waiting time of the reply message, and if the waiting time exceeds the set time, it is determined that the communication delay condition does not meet the preset communication condition.
For example, the network device may periodically send a probe packet (such as ICMP request) to the network server, where the sending period T is 2s, if the network device sends 5 probe packets and receives 5 reply packets to the network server in 5 periods, the waiting time of each reply packet is counted, and if the waiting time of each reply packet exceeds a set time (such as 500 ms, of course, a specific value may be flexibly set according to the actual requirement), it is determined that the communication delay is relatively large, and the communication delay condition does not meet the preset communication condition, where the preset communication condition may be understood that the waiting time of each reply packet does not exceed 500 ms.
Or after counting the waiting time of each reply message, if the waiting time of the reply message exceeding the set proportion exceeds the set time, the communication delay can be considered to be larger, if 5 messages are received, if the waiting time of more than 3 reply messages exceeds 500 milliseconds, the communication delay condition is considered to not meet the preset communication condition, and the preset communication condition can be understood as that the waiting time of the reply message exceeding the set proportion is not more than 500 milliseconds, namely the number of the reply messages with the waiting time not more than 500 milliseconds is larger than the set proportion.
Or, after counting the waiting time of each reply message, if the waiting time of any reply message exceeds the set time, the communication delay is considered to be larger, and the communication delay condition does not meet the preset communication condition.
Or, after counting the waiting time of each reply message, calculating to obtain an average waiting time, if the average waiting time exceeds the set time, considering that the communication delay is larger, and the communication delay condition does not meet the preset communication condition, wherein the preset communication condition can be understood that the time average waiting time does not exceed the set time.
Of course, in the above cases, if the waiting time does not exceed the set time, it is determined that the communication delay condition satisfies the preset communication condition (which may be considered as poor network signal quality at this time), and at this time, the communication under the first operator network may be maintained without performing the network handover.
In the implementation process, whether the communication link fails or not can be timely found by judging the communication delay condition, so that network switching is rapidly performed, and the communication stability is ensured.
On the basis of the above embodiment, the communication parameters may further include the number of reply messages, and when judging whether the communication quality condition meets the preset communication condition, it may be judged whether the number of reply messages is equal to the number of detection messages, if not, it is determined that the communication packet loss condition does not meet the preset communication condition.
For example, if the network device sends 5 probe messages to the network server, if no packet loss occurs, 5 reply messages should be received, so that it can be determined whether the number of received reply messages is equal to the number of probe messages, if not, that is, if the number of general reply messages is smaller than the number of probe messages, it is considered that there is a communication packet loss (at this time, it may be considered that a communication link between the base station and the network server is faulty), the communication quality is poor, at this time, it may be considered that the communication packet loss does not meet a preset communication condition, and at this time, the preset communication condition may be considered that the number of reply messages is equal to the number of probe messages. In this case, it is indicated that the communication quality of the current first communication link is poor, and network handover is required. Otherwise, if the number of the reply messages is equal to the number of the detection messages, the situation that the packet loss occurs is indicated, and network switching is not needed at this time.
In order to more accurately judge the communication packet loss situation, it may also be determined whether the number of reply messages received in the set period is equal to the number of detection messages, for example, if the network device sends 5 detection messages to the network server in 5 periods, if no communication delay occurs, the reply messages fed back by the network server should also be received in 5 periods, so if the number of reply messages received in the set period is not equal to the number of detection messages, it indicates that there is a possibility of packet loss situation, and the communication packet loss situation does not meet the preset communication condition. Otherwise, if the number of the received reply messages is equal to the number of the detection messages in the set period, the packet loss condition is indicated not to occur, and network switching is not required at this time.
In the implementation process, whether the communication link fails or not can be known in time by judging the communication packet loss condition, and network switching can be performed in time.
On the basis of the above embodiment, the communication parameters may include a waiting time of the reply message and the number of the reply messages, when judging whether the communication quality condition satisfies the preset communication condition, it may be judged whether the number of the reply messages is equal to the number of the detection messages, if so, it is judged whether the waiting time exceeds the set time, and if the waiting time exceeds the set time, it is determined that the communication delay condition does not satisfy the preset communication condition.
That is, if there is no packet loss, it is further determined whether there is a communication delay, at this time, if there is a communication delay, it is determined that the communication delay does not meet the preset communication condition, and if the number of reply messages is not equal to the number of detection messages, it is directly considered that there is a packet loss, and network switching can be directly performed.
It can be appreciated that the above embodiments illustrate that network switching is required when the communication delay condition or the communication packet loss condition does not satisfy the preset communication condition, so as to ensure network stability, and that network switching is required when neither of the cases satisfies the preset communication condition. If the preset communication condition is met, the network switching can be automatically performed without switching and the communication quality condition of the first communication link can be continuously detected as long as any one of the conditions is met.
On the basis of the above embodiment, in order to further determine the communication quality condition of the communication link, the communication quality condition may further include a signal strength, so that when determining whether the communication quality condition satisfies the preset communication condition, the signal strength of the first communication link is detected, and when the signal strength is smaller than the set signal strength, it is determined that the communication quality condition does not satisfy the communication condition.
The signal strength may refer to a signal strength of the first operator network, which may obtain a signal-to-interference-and-noise ratio (Signal to Interference plus Noise Ratio, SINR) of a network signal, and the signal strength is represented by the SINR, and if the SINR is smaller than a set SINR, the signal strength is smaller than the set signal strength, so that it may be determined that the communication quality condition does not meet a preset communication condition, and at this time, network handover may also be performed.
That is, whether the network switching is performed can be determined by at least one of the communication delay, the packet loss and the signal strength, if at least one of the three conditions does not satisfy the preset communication condition, the network switching is performed, otherwise, if the at least one of the three conditions satisfies the preset communication condition, the network switching is not performed, so that the communication quality of the communication link can be more comprehensively measured, and the problem of unstable signals caused by frequent network switching is avoided.
If the communication quality is judged only by the signal strength, the judgment may be inaccurate, for example, when an arrearage exists in a certain internet of things card, if the signal strength of the operator network is good, network switching is not performed, but at the moment, a packet loss condition or communication delay exists in a communication link, if the communication is continued by the current operator network, network communication is interrupted, and communication stability cannot be ensured. Therefore, the method and the device can ensure that the communication quality of the link can be detected more accurately by combining the communication packet loss condition and/or the communication delay condition so as to realize stable switching of the network.
On the basis of the embodiment, when the network is switched, the network equipment can acquire recorded access point names (Access Point Name, APNs) of different operators and user name passwords required by equipment dialing authentication, and the information corresponds to the SIM card slot one by one. After the network equipment is switched to the network of the second operator, the APN information and the user information corresponding to the card operator of the Internet of things can be obtained, and dial-up networking is performed.
The network device comprises a very important 5G Modem hardware layer, the system uses AT instructions to interact with the Modem, and the Modem establishes a physical channel (such as a first communication link or a second communication link) connection of data communication with the operator network. When the network equipment needs to dial, the network equipment can acquire the stored slot position information of the physical network card, the APN of the operator and the user information are issued to the Modem through the AT instruction, the Modem establishes network connection with the operator and then sends authentication information to the network server for authentication, and after the authentication is passed, the IP address required by data communication is distributed to the user, so that the dial-up internet surfing can be realized.
In order to ensure that the network signal does not jump frequently, the network device can also establish a network registration learning table according to different operators, wherein the network registration learning table is used for recording network frequency bands which are registered successfully in each dialing, selecting the frequency band which is registered with the largest dialing success frequency as the optimal frequency band for data communication, and locking the Modem to the frequency band for communication. For example, after switching to the second operator network, a plurality of communication frequency bands may be determined first, then dial-up networking is performed through each communication frequency band, the probability of successful dial-up networking of each communication frequency band is counted, and the communication frequency band with the highest probability is selected for communication.
For example, assuming that the Modem supports a plurality of communication bands of the second operator including Band1, band2, band, then an attempt may be made to dial-up the internet through each communication Band separately, and then the probability of successful internet surfing for each communication Band is counted. If the number of times of dialing is counted continuously (e.g. N is 10), the number of times of dialing is counted continuously (i.e. 10 times of dialing is performed in each communication frequency band per day), and the network registration learning table is updated in real time by taking the number of times as a counting period, i.e. after the network is switched to the second operator network again next time, dialing and surfing are continuously performed by taking 10 times as a period. Then, the probability P of successful dialing through each communication Band can be calculated, if the number of successful dialing in Band1 Band is M1, the number of successful dialing in Band2 Band is M2, and the number of successful dialing in Band N Band is Mn, then P (Bn) =mn/N.
And then selecting the maximum value in P (Bn) as the communication frequency band with the highest probability, and locking the Modem to the communication frequency band, so that the situation that data communication is unstable due to frequency band jump in the use process (for example, if the data communication cannot stably work in a frequency band with good signals, the problem that the data communication is delayed greatly or has packet loss possibly caused by poor network signal quality) can be avoided.
When the network device switches to the first operator network, the network device may also continue to determine the optimal communication band in the above manner, that is, select the communication band with the best signal quality for communication. If the network device may disconnect the currently connected operator network due to other reasons, if the network device is restarted, the network device continues to connect to the last operator network, and at this time, the selection of the communication frequency band may not be performed again, and at this time, the communication frequency band with the highest probability of dialing success recorded in the network registration learning table may be directly read for communication. For example, after the network device is connected to the first operator network at present and is restarted by unexpectedly disconnecting, whether the last connected network is the first operator network can be detected, so that whether the network switching is performed can be judged, if the last connected network is the first operator network, the communication frequency band with the largest dialing success probability recorded in the network registration learning table can be read to perform communication, so that the quick recovery of network communication can be realized, and if the last connected network is the second operator network, the network switching is indicated, at this time, the optimal communication frequency band can be continuously selected according to the above procedure, namely, the network surfing is performed again through each communication frequency band, then the communication frequency band with the largest dialing success probability is selected to perform communication, so that after the network is switched to the current operator network, the network is enabled to be in the communication frequency band with good quality, and the communication stability can be effectively improved.
On the basis of the above embodiment, in order to achieve stability of network signal switching, before switching to the second operator network, the communication quality condition of the second communication link corresponding to the second operator network may be detected, and if the communication quality condition meets a preset communication condition, switching may be performed.
For example, the communication quality of the second communication link may refer to the signal strength of the second operator network, and the signal strength may also refer to the SINR of the signal, where the preset communication condition may be understood as that the signal strength is greater than the set signal strength, that is, the SINR of the signal is greater than the set SINR, and if this condition is met, the network switching may be performed. If this condition is not met, the signal strength of the first communication link may be compared with the communication strength of the second communication link, if the signal strength of the first communication link is greater than or equal to the signal strength of the second communication link, communication under the first communication link may be maintained without switching, if the signal strength of the first communication link is less than the signal strength of the second communication link, switching may be continued, and switching to the second communication link may ensure that the network signal is better because the communication quality of the first communication link is not good at this time.
It will be appreciated that after switching to the second communication link, the network device may continue to detect the communication quality of the second communication link, and when the communication quality of the second communication link does not meet the preset communication condition, may continue to switch back to the first communication link. That is, the two communication links are backup links, so that the reliability of the network can be improved, and when the network fails or the data communication quality of a certain physical link is poor, the network can be rapidly switched automatically, thereby realizing the rapid recovery of the user data forwarding.
The network switching method can detect the communication quality of the link in real time, can automatically switch the network without human intervention, enhances the stability of the system and reduces the manpower maintenance cost. The method can be applied to the situations of intelligent medical treatment, high-speed toll stations, driving exams, disaster area emergency network opening and the like, and under the situations, network access is more convenient and rapid, and equipment deployment is more flexible.
