Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings. Wherein like elements in different embodiments are numbered with like associated elements. In the following description, numerous details are set forth in order to provide a better understanding of the present application. However, those skilled in the art will readily recognize that some of the features may be omitted or replaced with other elements, materials, methods in different instances. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.
Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.
The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).
Fig. 1 is a flowchart of an embodiment of a communication method for an internet of things device, where the method can be applied to the internet of things device. As shown in fig. 1, the communication method of the internet of things device provided in this embodiment may include:
and S104, connecting the network through one of the service code numbers in the eSIM card of the Internet of things equipment.
In this embodiment, a plurality of service code numbers are written in an eSIM card of the internet of things device. The service code number, i.e., Operational Profile, refers to a code number resource for using a data service. The service code number may be written in through a data line before the device leaves the factory, or may be written in through a remote configuration mode during the use of the device. Referring to fig. 2, fig. 2 is a schematic diagram of an embodiment of an eSIM Card of an internet of things device provided in the present invention, in this example, the eSIM Card is implemented by using an embedded universal Integrated Circuit Card (eUICC), and 3 service code numbers are written in the eSIM Card: service code number 1, service code number 2 and service code number 3. It should be noted that, in this embodiment, the number of service code numbers written in the eSIM card of the internet of things device may be increased or decreased according to actual needs, and is not limited to 3, for example, as few as 2, or as many as 20. In this example, the eSIM card further writes a seed code number, namely, Provisioning Profile, which refers to a code number resource with a global cellular mobile communication network connection capability, and is used for establishing initial connection and downloading card data.
In an optional implementation manner, multiple service code numbers in the eSIM card of the internet of things device may have different priorities, the priorities may be determined by comprehensively considering the network state and the tariff condition of each service code number, the better the network state is, the lower the tariff is, the higher the priority of the service code number is, and when in use, the service code number with the higher priority may be preferentially used. Taking fig. 2 as an example, if the service code number 1 is a medium priority, the service code number 2 is a low priority, and the service code number 3 is a high priority, the network is preferentially connected through the service code number 3 to receive and transmit service data. That is to say, the network can be connected through the service code number with the highest priority among the service code numbers in the eSIM card of the internet-of-things device.
It is to be understood that, in order to facilitate switching between different operator networks, in an alternative embodiment, the plurality of service code numbers written in the eSIM card belong to at least two operators, so that when a network of one operator fails, switching to a network of another operator can be performed, and the device can be kept online. Taking fig. 2 as an example, if the internet of things device is used in china, the service number 1 may be a service number of china telecommunications, the service number 2 may be a service number of china mobile, and the service number 3 may be a service number of china telecommunications.
And S105, monitoring the networking state of the Internet of things equipment in real time.
By monitoring the networking state of the Internet of things equipment in real time, the abnormal conditions of the network can be found in time. The real-time monitoring of the networking state of the internet of things device in the embodiment may be qualitative monitoring, for example, whether the network is in a connected state or a disconnected state; or may be quantitative monitoring, for example, real-time monitoring on network delay, network jitter rate, network throughput, network packet loss rate, and other indicators. For quantitative monitoring, the networking state of the internet of things device may be measured by at least one of network delay, network jitter rate, network throughput, and network packet loss rate.
And S106, when the networking state of the Internet of things equipment meets the preset condition, loading other service codes in the plurality of service codes to connect the network.
In this embodiment, the networking state of the internet of things device meeting the preset condition includes at least one of the following situations: in the off state; the network delay is greater than a preset delay threshold; the network jitter rate is greater than a preset jitter rate threshold; the network packet loss rate is greater than a preset packet loss rate threshold; the network throughput is less than a preset throughput threshold. The delay threshold, the jitter rate threshold, the packet loss rate threshold, and the throughput threshold may be set according to a specific application scenario. For example, for a more delay sensitive application, a smaller delay threshold may be set; otherwise, a larger delay threshold may be set.
When the networking state of the Internet of things equipment meets the preset condition, the other service code numbers in the plurality of service code numbers can be loaded to connect the network, the service code numbers are replaced, and stable and reliable network connection is provided for the Internet of things equipment. Taking fig. 2 as an example, if the currently used service code number 3 is connected to the network, when the network delay is greater than the preset delay threshold, the network may be connected by loading the service code number 1 or the service code number 2.
According to the communication method of the internet of things equipment, firstly, one of the plurality of service code numbers in the eSIM card of the internet of things equipment is connected with the network, then, the networking state of the internet of things equipment is monitored in real time, and when the networking state of the internet of things equipment meets the preset condition, other service code numbers in the plurality of service code numbers are loaded to connect with the network, so that the real-time seamless switching of the service code numbers can be realized. Because a plurality of service code numbers are stored in the eSIM card of the Internet of things equipment, when the service code numbers are switched, the service code numbers do not need to be downloaded from the code number management platform, the time for switching the service code numbers can be greatly shortened, and the Internet of things equipment is kept on line in real time. Furthermore, the method provided by the embodiment can be effectively compatible with the hardware design of the existing internet of things equipment, the hardware circuit design does not need to be changed, and the hardware cost is not increased.
When the deployment area of the internet of things equipment is uncertain, for example, for an internet of things equipment which is going to be sold to multiple countries such as the united kingdom, germany and the united states, the service code number cannot be preset at the time of factory shipment. When the use place of the internet of things equipment is changed, the original service code number can not be used, for example, for a language translator used in China, the original service code number cannot be used after a user arrives in the United kingdom. In view of the above situation, the present embodiment provides a communication method for an internet of things device, which can write a plurality of service numbers in a remote configuration manner when the internet of things device is powered on and started up for the first time or when none of the original service numbers is available. Referring to fig. 3, fig. 3 is a flowchart of a communication method of an internet of things device according to another embodiment of the present invention. As shown in fig. 3, on the basis of the embodiment shown in fig. 1, the communication method of the internet of things device provided in this embodiment may further include, before step S104:
s101, establishing initial connection through a seed code number preset in the Internet of things equipment, and uploading the mobile country code to a code number management platform, so that the code number management platform determines a plurality of service code numbers of the Internet of things equipment according to the mobile country code uploaded by the Internet of things equipment.
The internet of things equipment can establish initial connection through a seed code number preset in the internet of things equipment when no service code number is available, such as when the internet of things equipment is powered on and started for the first time or all service code numbers are invalid. When the Internet of things equipment realizes networking through a preset seed code number, the current MCC is uploaded to a code number management platform.
The code number management platform in this embodiment may include a service platform and a Subscription Manager Data Preparation (SM-DP +) platform, and is configured to provide a required service code number to an internet of things device. The Code number management platform configures a Code number policy, which may be, for example, a mapping relationship between a Mobile Country Code (MCC) and a Mobile Network Code (MNC), so that the Code number management platform can determine the MNC corresponding to the package according to the MCC reported by the internet of things device, and finally determine a plurality of service Code numbers of the internet of things device.
Table 1 is a partial mapping relationship table of MCC and MNC in the code number policy provided in an embodiment, where MCC is 460, MNC is 01, MNC is 03, MNC is china telecom, MCC is 208, france, MNC is 10, SFR, MNC is 20, BOUYGTE L, when the internet-of-things device is powered on in china for the first time and networking is implemented by a preset seed code number, "460" is uploaded to the code number management platform, the code number management platform may distribute multiple service numbers belonging to china telecom and chinese telecom to the internet-of-things device according to the code number policy shown in table 1, when the internet-of-things device is moved to france, the original service number will not be used, at this time, the internet-of-things device, after networking is implemented by the preset seed code number, may upload "208" to the code number management platform, the code number management platform may distribute multiple services belonging to the operator SFR and the operator, the numerous SFR and the SFR L to the internet-of the operator according to the code number policy shown in table 1.
TABLE 1
| MCC | MNC |
| 460 | 01、03 |
| 208 | 10、20 |
And the number is written in the air according to the mobile country code, so that the Internet of things equipment can be used across the border. For example, when the internet of things device moves from china to france, the original service code number cannot be used. And the application can restart reporting the MCC, acquire the business code number corresponding to France and support cross-border use of equipment. And a plurality of service code numbers are acquired at one time, so that the service code numbers are convenient to switch. The mobile country code is reported to obtain the service code number, the service code number does not need to be preset in the Internet of things equipment, the card can be opened as required, and unnecessary cost is avoided. If a mode of presetting a service code number is adopted, extra cost is generated in the period from the code number presetting to the time when the Internet of things equipment is put into formal use.
S102, downloading a plurality of service code numbers of the Internet of things equipment from the code number management platform.
After the number management platform configures a plurality of service numbers for the internet of things device, the internet of things device can acquire an Activation Code (AC for short) from the service platform, and then use the AC to download the plurality of service numbers belonging to the internet of things device from the SMDP +.
S103, writing the downloaded service code numbers into an eSIM card of the Internet of things equipment.
The plurality of service code numbers can be written into the eSIM card of the internet of things device according to the priority order or the downloading order of the plurality of service code numbers.
In the communication method of the internet of things device provided by this embodiment, on the basis of the above embodiment, an initial connection is established through a seed code number preset in the internet of things device, a mobile country code is uploaded to a code number management platform, a plurality of service code numbers determined according to the uploaded mobile country code are downloaded from the code number management platform, so that the internet of things device supports cross-border use, and the plurality of service code numbers are written into an eSIM card of the internet of things device at one time, so that the internet of things device can realize real-time seamless switching of the service code numbers in a subsequent use process. A plurality of service code numbers are written in an eSIM card of the Internet of things equipment through remote configuration, so that the card can be opened as required, and the service code numbers do not need to be downloaded from a code number management platform when the service code numbers need to be switched, thereby greatly shortening the time for switching the service code numbers and keeping the Internet of things equipment on line in real time. Meanwhile, the method provided by the embodiment can also be effectively compatible with the hardware design of the existing Internet of things equipment, the hardware circuit design does not need to be changed, and the hardware cost cannot be increased.
