An eSIM card can be arranged in the communication module, so that communication based on a cellular network is realized, and the Internet of things equipment can normally complete the Internet of things function.
In some special scenarios, however, a cellular network signal disruption or quality instability may occur. For example, when a communication network of an operator has a large-area fault, internet of things devices using the communication network of the operator cannot communicate with each other. Or for example, when the internet of things device completes moving across regions and countries while being offline, the network environment changes completely after the internet of things device comes online again.
In the prior art, the internet of things equipment cannot be self-adaptive to a changing network environment, and the normal use of the internet of things equipment is influenced by an unstable network condition.
Exemplary method
Therefore, embodiments of the present invention provide a communication method for an internet of things device, so as to at least solve the above technical problems in the prior art. As shown in fig. 1, the method in this embodiment is applied to a communication module of an internet of things device. The communication module can be built-in or externally connected with the Internet of things equipment. A network card (namely an eSIM card) is arranged in the communication module, so that communication based on a communication network is realized, and the equipment of the Internet of things can normally complete the function of the Internet of things. Generally, the built-in network card may include connection parameters of a plurality of communication networks, so as to facilitate corresponding access to a specific communication network, that is, the communication module may select a connection from the plurality of communication networks and perform communication. In this embodiment, it may be assumed that the network card of the communication module includes 1 connection parameter (hereinafter referred to as "mobile number data") based on the "china mobile" network and 1 connection parameter (hereinafter referred to as "mobile number data") based on the "china unicom" network. The method comprises the following steps:
The communication module is internally or externally connected with the Internet of things equipment and can be selected from a plurality of communication networks to be connected and communicated. It is assumed that the communication module includes "mobile code number data" and "unicode number data". The communication module can be connected to a communication network provided by China Mobile based on 'mobile code number data', and can be connected to a communication network provided by China Unicom based on 'Unicom code number data'.
The current network is the communication network that the communication module is using. Whereas the alternative networks are all communication networks that are not currently in use. The current network and the alternative network depend on the current usage status with no substantial difference. In this embodiment, it is assumed that the communication module is currently connected to a communication network provided by "china mobile" and can perform normal communication. At this time, the communication network provided by the China Mobile is the current network, and the communication network provided by the China Unicom is the alternative network.
The communication module is in normal communication, namely can be connected to the server, and acquires the first connection strategy from the server through the current network. The first connection policy is a policy mechanism for the communication module to perform preferential selection and handover among multiple communication networks (i.e., the current network and each of the alternative networks). The first connection policy may be formulated by the server according to an actual environment in which the communication module is located. In the scenario of this embodiment, the communication module may acquire the first connection policy under a specific condition. The method specifically comprises the following steps:
and when the first connection strategy is generated in the server, the first connection strategy is obtained from the server. The server may occasionally generate a new first connection policy, and when the server generates the first connection policy, the server may issue the first connection policy to the communication module. Or when the current network meets the preset condition, the first connection strategy is obtained from the server. For example, when the signal strength of the current network is lower than a certain threshold, the first connection policy is acquired and the method in the embodiment is executed. I.e. to implement adaptive network selection and handover based on the first connection policy when the communication network signal is unstable.
It should be noted that, the technical problem addressed by the present invention is that the internet of things device cannot be adaptive to a changing network environment. And the first connection policy is a policy mechanism for the communication module to select and switch among the plurality of communication networks. It is therefore an object of this embodiment to enable a communication module to adaptively select and switch a communication network through the first connection policy.
That is, according to the first connection policy, the communication module may compare the plurality of communication networks and select a communication network having the best quality. The first connection policy may include a roaming policy, a signal strength policy, and a system policy.
Then, according to the first connection policy, from the current network and the at least one alternative network, determining that the target network may be: and comparing the roaming types, the signal strengths and the system information of the current network and each alternative network according to the roaming strategy, the signal strength strategy and the system strategy to determine the target network. That is, the communication module performs selection based on roaming, signal strength, and three dimensions of the LTE system, so as to determine the relatively most available communication network as the target network. In this embodiment, it is assumed that the communication network provided by "china unicom" is determined as the target network according to the first connection policy.
It will be appreciated that the target network is also one of the plurality of communication networks described above, and that it differs from the current network and the alternative network only in the use state, without substantial difference.
And 103, establishing communication connection based on the target network.
And the target network represents an optimal communication network determined according to the first connection strategy. I.e. the communication module is targeted for adaptive network handover under certain conditions. Therefore, the communication module only needs to disconnect the current network and establish communication connection based on the target network, and self-adaptive network switching is completed under the condition that the network state is unstable. It should be noted that, in a scenario of performing the method in this embodiment in a loop, the target network determined in the previous execution is equivalent to the current network in the subsequent execution.
In this embodiment, that is, the communication module disconnects the communication network provided by "china mobile", and establishes communication connection with the communication network provided by "china unicom" based on the "unicode number data", thereby completing network handover.
Specifically, a connection parameter corresponding to the target network may be determined first; and establishing communication connection according to the connection parameters corresponding to the target network. The connection parameter may specifically be an ICCID, an EID, an APN, operator information, and the like corresponding to the target network.
In addition, the communication terminal can report the communication state of the internet of things device to the server according to a preset time period, so that the server can generate a new first connection strategy conveniently.
According to the technical scheme, the beneficial effects of the embodiment are as follows: determining and connecting a target network according to a first connection strategy by acquiring the first connection strategy; therefore, the optimal communication network is selected under the condition that the network state is unstable, and the self-adaptive network switching is completed; the problem of the thing networking device can't realize self-adaptation to the network environment that changes, can't normal use under unstable network condition is solved.
Fig. 1 shows only a basic embodiment of the method of the present invention, and based on this, certain optimization and expansion can be performed, and other preferred embodiments of the method can also be obtained.
Fig. 2 shows another embodiment of the communication method of the internet of things device according to the present invention. The present embodiment further describes a determination process of the current network on the basis of the foregoing embodiments. Before the communication module connects to the server based on the current network, the method further comprises the steps of:
In the case where the communication module is first powered up, or powered back up, it will typically be in a state where no communication connection is established. That is, all communication networks are the alternative networks at this time. And because the communication connection is not established, the first connection strategy cannot be obtained from the server, and a certain communication network connection cannot be selected according to the first connection strategy.
In this case, a certain communication network may be determined from the candidate networks to be connected according to the second connection policy stored in advance. The determined communication network may correspond to the current network in the foregoing embodiment.
The actual content of the second connection policy in this embodiment may be similar to the first connection policy, which is not described herein again. The second connection policy may be a default policy set in the communication module, or may be a first connection policy used in the last working process of the communication module. And need not be described in further detail herein.
After determining the current network, determining a connection parameter corresponding to the current network; and establishing communication connection according to the connection parameters corresponding to the current network. The connection parameter may specifically be an ICCID, an EID, an APN, operator information, and the like corresponding to the target network.
Fig. 3 shows another embodiment of the communication method of the internet of things device according to the present invention. The present embodiment is described with reference to another specific scenario on the basis of the foregoing embodiment. In this embodiment, it is assumed that, as the communication module in the embodiment shown in fig. 1 restarts to operate in the area a outside china, the original communication networks are all in the cross-border roaming state. In this case, the method in this embodiment includes the steps of:
When the communication module is powered back up in area a, the current network may be determined according to the flow in the embodiment shown in fig. 2. The description in this embodiment is not repeated. In this embodiment, it is assumed that the current network is a communication network provided by "china mobile".
After the communication connection with the current network is established, the first connection strategy aiming at the specific situation of the area A can be obtained from the server. Meanwhile, in this embodiment, an additional connection parameter of the communication network provided by the operator B in the area a is also used. I.e. the communication network provided by operator B may be used as an additional alternative network in this embodiment.
And step 304, determining a target network from the current network and the alternative network according to the first connection strategy.
As is apparent from this embodiment, the "mobile number data" and the "unicode number data" pre-installed in the communication module are both in the cross-border roaming state. However, the communication network provided by the operator B is not in a roaming state because it is a local network.
Typically, in the first connection policy, roaming is selected to be turned off, i.e., a local communication network is preferentially selected for connection. The communication network provided by operator B will be selected as the target network in this embodiment according to the first connection policy.
Similarly, according to the connection parameters of the communication network provided by the operator B, a communication connection can be established with the communication network provided by the operator B, i.e. the target network. In the embodiment, the communication module is adaptively switched to the local communication network for communication on the premise of cross-region or cross-border, and cross-border roaming service is automatically avoided.
