Fig. 1 is a schematic view of an application architecture of a communication handover method according to an embodiment of the present invention. The application architecture shown in fig. 1 does not include an operator platform and an internet of things device, and may be implemented by referring to the prior art, which is not limited in this embodiment. As shown in fig. 1, the internet of things communication module provided in this embodiment is preset with a soft SIM card, where the soft SIM card is a virtualized SIM card that realizes a hardware SIM card communication function through computer software, and for example, information of the hardware SIM card may be stored in a soft SIM card file, and the connection with the cellular mobile communication network is realized by running the soft SIM card file. The entity SIM card in this embodiment may be a plug-in SIM card or an embedded SIM card. The Internet of things equipment can obtain the capability of connecting the cellular mobile communication network through the Internet of things communication module and the entity SIM card. If the SIM card is a plug-in SIM card, the card slot can be arranged on the Internet of things equipment or can be directly arranged on the Internet of things communication module; if the SIM card is embedded, the eSIM chip can be embedded into the Internet of things equipment and can also be directly embedded into the Internet of things communication module.

Fig. 2 is a flowchart of an embodiment of a communication switching method provided in the present invention, which can be applied to an internet of things communication module. As shown in fig. 2, the communication handover method provided in this embodiment may include:
s201, connecting a network through a solid SIM card connected with the Internet of things communication module.
When the internet of things equipment is started or restarted, the main controller of the internet of things equipment controls the internet of things communication module to be connected with the network. The communication module of the internet of things is connected with the network through the entity SIM card connected with the communication module of the internet of things after receiving the control command of the main controller for connecting the network. I.e. when the device is powered on and restarted, the network provided by the physical SIM is preferentially used.
The connection network related in this embodiment includes a process of establishing an initial connection with a mobile communication network of an operator, and after the network is successfully connected, the connection network may be kept in long connection with the service platform, so that the service platform can timely grasp the working state of each piece of internet-of-things equipment.
S202, monitoring the network state of the entity SIM card in real time according to the monitoring strategy.
And the Internet of things communication module monitors the network state of the entity SIM card in real time according to the monitoring strategy. By real-time monitoring, abnormal conditions in the entity SIM network can be found in time. The monitoring strategy in this embodiment may be qualitative monitoring, such as connection success and connection failure; the monitoring may also be quantitative monitoring, for example, real-time monitoring may be performed on indicators such as communication delay, jitter rate, throughput, and packet loss rate. For quantitative monitoring, the network status of the physical SIM card may be measured by at least one of latency, jitter rate, throughput, and packet loss rate. In particular, the monitoring may be realized by a ping command, for example.
S203, judging whether the network state of the entity SIM card meets the triggering condition of switching the network. If yes, executing step S204; otherwise, the network service provided by the entity SIM card continues to be used, and step S202 is executed to continuously monitor the network status of the entity SIM card.
The triggering condition for switching the network can be determined according to the application scene of the internet of things equipment. For the application with sensitive time delay, such as real-time public transport, the triggering condition can be that the time delay is more than or equal to 10 seconds; for the application with sensitive data, such as remote intelligent meter reading service, the triggering condition may be that the packet loss rate is greater than or equal to 10%. When the network state provided by the entity SIM card cannot meet the usage requirements of the internet of things device, for example, network connection fails, communication delay is too long, packet loss rate is too high, and the like, network switching is required.
And S204, connecting a network through a preset soft SIM card in the communication module of the Internet of things.
When the network state of the entity SIM card meets the triggering condition of switching the network, the communication module of the Internet of things starts a standby network provided by a soft SIM card preset in the communication module of the Internet of things, so that the equipment of the Internet of things can timely and effectively communicate.
In the communication switching method provided by this embodiment, a network is connected through a solid SIM card connected to an internet of things communication module; monitoring the network state of the entity SIM card in real time according to a monitoring strategy; judging whether the network state of the entity SIM card meets the triggering condition of switching the network; and if the network state of the entity SIM card meets the triggering condition of switching the network, connecting the network through a soft SIM card preset in the communication module of the Internet of things. The soft SIM card is preset in the communication module of the Internet of things, and is started to provide a standby network when needed, so that the connection with a cellular mobile communication network is ensured, the communication is timely and effectively carried out, the reliability of the communication is improved, operation and maintenance personnel are not needed for carrying out field maintenance, and the maintenance cost is reduced.
The demands of different kinds of internet of things devices on the communication quality of the mobile communication network are different. For the internet of things equipment for realizing real-time public transportation, under the condition that the bus moves rapidly, the acquired position information of the bus needs to be reported to the server through the internet of things communication module, so that the bus taking guidance is performed on a user, the tolerance of the communication delay is low, and the overlong communication delay can greatly reduce the user experience. For the internet of things equipment for realizing remote intelligent meter reading services such as an intelligent electric meter and an intelligent water meter, the internet of things equipment has no high requirement on communication delay, but has a higher requirement on packet loss rate, and after all, the accuracy of data transmission directly concerns the economic benefits of users and manufacturers. If the communication quality is monitored by adopting the same monitoring strategy without distinguishing, the requirements of different application scenes on the communication quality cannot be met.
Therefore, in order to meet the requirement of the internet of things device for the communication quality in different application scenarios, in this embodiment, a user is allowed to set a trigger condition for switching a network for each internet of things communication module through a service platform according to an International Mobile Equipment Identity (IMEI) of the internet of things communication module. For example, for an internet of things device for realizing real-time bus, the triggering condition for switching the network may be set to a communication delay of 10 seconds or more; for the internet of things equipment for realizing remote intelligent meter reading services such as an intelligent electric meter and an intelligent water meter, the triggering condition for switching the network can be set to be that the packet loss rate is more than or equal to 10%. Specifically, before monitoring the network state of the entity SIM card, the Internet of things communication module firstly receives a trigger condition for switching the network sent by the service platform, and then determines a monitoring strategy according to the trigger condition. If the triggering condition is that the communication delay is greater than or equal to 10 seconds, the monitoring strategy can be to obtain the difference value between the sending time and the receiving time of the data packet and judge whether the difference value is greater than or equal to 10 seconds; if the triggering condition is that the packet loss rate is greater than or equal to 10%, the monitoring policy may be to obtain a ratio of the number of lost data packets to all the transmitted data packets, and determine whether the ratio is greater than or equal to 10%. And personalized services are provided for the Internet of things equipment under different application scenes.
According to the method and the device, the soft SIM card is preset in the communication module of the Internet of things, and when the network provided by the entity SIM card cannot meet the application requirement or the entity SIM fails, the soft SIM card is started to provide a standby network. Therefore, the seed code number needs to be written into the soft SIM card. If adopt the mode of seed code number of writing in into one-to-one, 10000 seed code numbers just need to 10000 thing networking communication module, lack one can not. Considering that the probability that a plurality of internet of things communication modules start the soft SIM card at the same time is low, on the basis of any one of the above embodiments, the present embodiment provides a method for sharing the seed code number by the soft SIM card, so as to improve the utilization rate of the seed code number and reduce the cost. In the communication switching method provided in this embodiment, a soft SIM card preset in an internet-of-things communication module includes a plurality of seed code numbers, and if a network state of an entity SIM card satisfies a trigger condition for switching a network, one seed code number is selected from the plurality of seed code numbers included in the soft SIM card according to a preset random algorithm, and an initial connection is established with an operator network using the selected seed code number.
For example, the soft SIM cards of the first N1 communication modules of the internet of things include the same second N2 seed code numbers, and the second number is smaller than the first number, so that (N1-N2) seed code numbers can be saved. It can be understood that the second number is positively correlated with the first number, that is, the more the number of the communication modules of the internet of things is, the more the number of the required seed codes is. In actual use, the deployment environment of the internet of things equipment can be comprehensively considered, and the worse the environment is, the higher the probability of starting the soft SIM card is, and more seed code numbers are needed.
For a soft SIM card including multiple seed numbers, when the soft SIM card is enabled, a seed number needs to be selected from the multiple seed numbers first for establishing an initialization connection. If the soft SIM cards in the two communication modules of the Internet of things select the same seed code number, conflict is generated, and the standby network cannot be started successfully. Therefore, in order to avoid collision and improve the success probability of activating the standby network, in this embodiment, one seed code number may be selected from the plurality of seed code numbers included in the soft SIM card according to a preset random algorithm. For example, if the soft SIM card includes N seed code numbers, which are numbered sequentially from 1 to N, a random number with a value range between [1, N ] may be determined according to a preset random algorithm, and the seed code number of the corresponding number may be selected according to the determined random number. The present embodiment is not particularly limited to the random algorithm, and an existing random algorithm or a random algorithm that will occur in the future may be used.
Fig. 3 is a flowchart of a communication handover method according to another embodiment of the present invention. As shown in fig. 3, the communication handover method provided in this embodiment may include:
s301, connecting a network through a solid SIM card connected with the Internet of things communication module.
S302, receiving a trigger condition for switching the network, which is sent by the service platform.
And S303, determining a monitoring strategy according to the trigger condition.
And S304, monitoring the network state of the entity SIM card in real time according to the monitoring strategy.
S305, judging whether the network state of the entity SIM card meets the triggering condition of switching the network. If yes, executing step S306 to start the standby network; otherwise, continuing to execute step S304 to monitor the network status of the physical SIM card.
S306, selecting one seed code number from the plurality of seed code numbers included in the soft SIM card according to a preset random algorithm, and establishing initialization connection with the operator network by using the selected seed code number.
According to the communication switching method provided by the embodiment, on the basis of providing a standby network through the soft SIM card and improving the communication reliability, the triggering condition of the switching network sent by the service platform is further received, and the monitoring strategy is determined according to the triggering condition, so that different requirements on communication quality under different application scenes can be met, and personalized service is provided for a user; through presetting a plurality of seed code numbers in soft SIM card, realize sharing seed code number in thing networking communication module, improved the utilization ratio of seed code number.
Although when the network state of the entity SIM card meets the triggering condition of switching the network, a standby network is provided by starting the soft SIM card, so that the communication is guaranteed. However, the failure causes of network switching are various, such as loose plug-in solid SIM card, burning out eSIM chip, low throughput, long communication delay, network failure of the operator, and the like, and different measures need to be taken to improve the success rate of starting the standby network for different failure causes. Therefore, in this embodiment, when the network state of the entity SIM card meets the triggering condition for switching the network, the internet of things communication module determines a fault cause for triggering network switching, where the fault cause includes a network side fault and an entity SIM card fault. The handover caused by the operator network is determined as a network side fault, which may include, for example, that the operator network is uncovered, the operator network fault and communication indexes such as time delay, throughput, packet loss rate, jitter rate, and the like do not meet the standard. The switching caused by the physical SIM card is determined as a physical SIM card failure, which may include, for example, card looseness, a SIM card failure, and the like.
After the fault reason for triggering network switching is determined, for the soft SIM card with a plurality of preset seed code numbers, different measures can be taken for different fault reasons, so as to shorten the time for starting the standby network and improve the success rate of starting the standby network. Specifically, if the failure cause is a network side failure, selecting a seed code number belonging to a different operator from a plurality of seed code numbers included in the soft SIM card, and establishing an initialization connection; and/or if the failure reason is the failure of the entity SIM card, selecting one seed code number from a plurality of seed code numbers included by the soft SIM card according to a preset random algorithm and/or the priority of the seed code numbers, and establishing the initialization connection.
For example, the physical SIM card uses a cellular mobile communication network provided by operator a, and when the network of operator a fails, the triggering condition for switching networks is met, and the network needs to be connected through a preset soft SIM card. If the seed code number of the operator a is still selected from the plurality of seed code numbers included in the soft SIM card at this time, the network cannot be successfully connected. The above process of selecting the seed number and establishing the initial connection needs to be repeated. Multiple attempts may be required to successfully enable the standby network, which is time consuming. In this embodiment, if it is determined that the cause of the failure is a network side failure, when the seed code number is selected, the seed code number belonging to the same operator as the current entity SIM card is excluded, so that the time for starting the standby network can be effectively shortened, and the success rate for starting the standby network is improved.
In order to facilitate the service platform to allocate the service code number to the communication module of the internet of things according to the fault reason, in the embodiment, after connecting a network through a soft SIM card preset in the communication module of the internet of things, the communication module of the internet of things further sends the fault reason to the service platform, so that the service platform allocates the service code number to the communication module of the internet of things according to the fault reason; acquiring a service code number distributed to the Internet of things communication module by a service platform; and receiving and transmitting the service data according to the service code number.
After receiving the fault reason sent by the internet of things communication module, the service platform can generate a service code number according to the fault reason and store the generated service code number in the SMDP +. For example, when the failure cause is a network side failure, the service platform allocates service code numbers of other operators to the communication module group of the internet of things to ensure the receiving and sending of service data. The communication module of the internet of things acquires a service Activation Code (AC) from the service platform, and downloads a service Code number from the SMDP + by using the service AC to receive and send service data.

s401, connecting a network through a solid SIM card connected with the Internet of things communication module.
S402, monitoring the network state of the entity SIM card in real time according to the monitoring strategy.

If yes, go to step S404; otherwise, the network service provided by the entity SIM card continues to be used, and step S402 is executed to continuously monitor the network status of the entity SIM card.
S404, determining a fault reason for triggering network switching.
S405, according to the fault reason, selecting one seed code number from the plurality of seed code numbers included in the soft SIM card, and establishing the initialization connection.
