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).
It should be noted that the industry has different expressions for esims, and for example, the expression may also be called an embedded Universal Integrated Circuit Card (eUICC). Although the present application is collectively described as eSIM, the present application is not limited thereto.
The seed code number includes SIM card data required for establishing an initialization connection with an operator network, for example, authentication data required for establishing an initialization connection may be included, and specific contents and data formats may be different for different operators or different communication protocols, so the specific contents and data formats of the seed code number are not limited in the present application. In one embodiment, the seed code number may include, for example: public Land Mobile Network (PLMN), International Mobile Subscriber Identity (IMSI), Integrated Circuit Card Identity (ICCID), authentication Key (KI), and Operator root Key (OP).
Fig. 2 is a flowchart of an embodiment of a method for sharing seed code numbers by esims according to the present invention, where the method can be applied to devices in the internet of things. As shown in fig. 2, the method for sharing seed code numbers by esims provided in this embodiment may include:
s201, obtaining a shared file pre-stored in the Internet of things equipment, wherein the shared file comprises a plurality of seed code numbers.
In this embodiment, the internet of things device can acquire the shared file pre-stored in the internet of things device when the internet of things device is started. The shared file can be generated by a virtual card factory according to a seed code number provided by an operator, and is downloaded to the internet of things equipment for storage before the internet of things equipment leaves a factory. In this embodiment, the file format, the file size, the storage format, the storage location, and the like of the shared file are not limited. The virtual card factory can be realized through software, for example, the virtual card factory can be a client, inputs the seed code number, and outputs the shared file according to a preset rule.
Considering that the probability that the internet of things equipment is connected with the network at the same time is low, the shared file can comprise a plurality of seed code numbers for the use of a plurality of internet of things equipment so as to realize the sharing of the seed code numbers. In an alternative embodiment, the shared file includes a first number N1 of seed code numbers, and the shared file is provided for a second number N2 of internet-of-things devices, where the second number is greater than the first number. Then (N2-N1) seed code numbers can be saved compared to the prior art shown in fig. 1. It can be understood that the first number is positively correlated with the second number, that is, the more internet of things devices using the shared file, the more seed code numbers are required; the first number is positively correlated with the networking frequency of the internet of things equipment, namely the lower the networking frequency of the internet of things equipment is, the fewer the number of the required seed code numbers is.
The Internet of things equipment provider acquires the right to use the seed code number from the operator and pays corresponding expenses, the number of the needed seed code numbers is reduced through sharing files, and the cost can be reduced; the seed code number is used as a communication resource and is not inexhaustible, the number of the required seed code numbers is reduced by sharing files, and the utilization rate of the seed code numbers can be improved.
For example, in the existing one-to-one writing-in mode of the seed code number, 10000 seed code numbers are needed for 10000 internet of things devices, and the lack of one is not available. And the mode of sharing files is adopted, only 1000 seed code numbers are needed probably, and 10000 Internet of things devices are used together. The number of required seed code numbers can be greatly reduced.
In actual use, the number of the internet of things devices, the networking frequency of the internet of things devices and the requirement for the networking success rate can be comprehensively considered, and the number of the seed code numbers included in the shared file can be determined.
S202, selecting a seed code number from the seed code numbers included in the shared file according to a preset selection strategy.
Only one seed code number is needed when the Internet of things equipment and the operator network are in initial connection. In this embodiment, after the shared file is obtained, the plurality of seed code numbers included in the shared file may be obtained by analyzing the shared file. When the internet of things equipment judges that the current service code number is unavailable, one seed code number can be selected from the seed code numbers included in the shared file according to a preset selection strategy.
If two pieces of internet-of-things equipment establish initialization connection with an operator network at the same time and the same seed code number is selected, conflict is generated, and the establishment of the initialization connection cannot be completed. In order to avoid collision and improve the success probability of establishing the initialization connection, in an alternative embodiment, one seed code number may be selected from the seed code numbers included in the shared file according to a preset random algorithm. For example, if the shared file 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.
And S203, writing the selected seed code number into an eSIM chip of the Internet of things equipment.
In this embodiment, after one seed code number is selected from a plurality of seed code numbers included in the shared file, the selected seed code number is written into an eSIM chip of the internet of things device, so as to be used when an initialization connection is established with an operator network.
In the prior art, the seed code number needs to be written into the eSIM chip one by a card production line, the steps are complicated, and the production process is long. In the application, when the internet of things equipment needs to be connected with the operator network, the selected seed code number is written into the eSIM chip of the internet of things equipment as required, so that the production flow is simplified. It should be noted that, in the two networking processes, the same internet of things device may write different seed code numbers.
And S204, establishing an initialization connection with the operator network by using the seed code number written in the eSIM chip.
In this embodiment, after the selected seed code number is written in the eSIM chip of the internet of things device, an initialization connection may be established with the operator network using the seed code number written in the eSIM chip. The procedure for establishing an initial connection with the operator network is the same as in the prior art and will not be described here.
It should be noted that, if the initialization connection setup fails due to the seed code number collision, the above steps S202 to S204 are repeatedly executed until the initialization connection setup is successful.
In the method for sharing seed code numbers by eSIM provided by this embodiment, a shared file pre-stored in an internet of things device is obtained, where the shared file includes a plurality of seed code numbers; selecting a seed code number from seed code numbers included in the shared file according to a preset selection strategy; writing the selected seed code number into an eSIM chip of the Internet of things equipment; and establishing an initialization connection with the operator network by using the seed code number written in the eSIM chip. The seed code numbers can be shared among a large number of Internet of things devices through the shared file comprising the plurality of seed code numbers, so that the number of the needed seed code numbers is reduced, and the utilization rate of the seed code numbers is improved; the seed code number is written into the eSIM chip by the Internet of things equipment as required, and the seed code number is not required to be written into the eSIM chip one to one by a card production line, so that the production flow is simplified. And the cost can be effectively reduced.
On the basis of the above embodiments, in order to improve security and avoid malicious rewriting of the shared file, the shared file in an embodiment may further include a hash digest, and before selecting one seed code number from the seed code numbers included in the shared file according to a preset selection policy, the integrity of the shared file is verified according to the hash digest. Specifically, after the shared file is acquired, the hash digest can be calculated by adopting a predetermined hash algorithm according to the other parts of the shared file except the hash digest, if the calculated hash digest is consistent with the hash digest included in the shared file, the shared file is determined to be complete and usable, and the subsequent steps are continuously executed; otherwise, the shared file may be damaged, and the subsequent steps are stopped.
In another embodiment, the shared file may further include an asymmetrically encrypted digital signature, and the shared file is verified according to the digital signature before one seed code number is selected from the seed code numbers included in the shared file according to a preset selection policy. Specifically, after a shared file is obtained, an asymmetrically encrypted digital signature is obtained from the shared file, a public key is used for verifying the digital signature, and if the verification is passed, the subsequent steps are continuously executed; otherwise, stopping executing the subsequent steps.
Optionally, the shared file may include both the hash digest and the asymmetrically encrypted digital signature, and the security is further improved by double verification.
The degree of network coverage varies from operator to operator in the same area. If the internet of things device depending on the operator a is deployed in an area where the network of the operator a is uncovered or poorly covered, the initialization connection cannot be established due to the network coverage, and therefore, a stable and reliable initialization connection cannot be provided depending on a single operator. In the prior art, the seed code number is written in a one-to-one mode and cannot be changed after being written once, and the Internet of things equipment can only rely on a single operator to establish initial connection, so that the reliability is poor. In order to provide stable and reliable initialization connection, the multiple seed code numbers included in the shared file belong to multiple operators, the priorities of the operators are different, and the priorities are used for determining the use sequence of the seed code numbers. The priority of each operator may be set in advance according to the network coverage of each operator, or may be set according to the signal quality of each operator network detected by the internet of things device, where the higher the signal quality is, the higher the priority is. For example, if the shared file includes seed numbers of three operators, namely china mobile, china unicom and china telecom, when the internet of things device establishes the initial connection, it may first select one seed number from the seed numbers of the china mobile to establish the initial connection, and if the internet of things device fails, it may continue to select one seed number from the seed numbers of the china unicom to establish the initial connection. By providing seed code numbers with multiple priorities, stable and reliable initialization connection can be conveniently provided even under the condition of uneven network coverage.
TABLE 1
Figure DEST_PATH_IMAGE002
Table 1 is an example of a storage format of a shared file provided in an embodiment. The File info is attribute information of the shared File, and specifically may include information such as the number of operators and the File version number; profile info 1 indicates first operator resource information, Profile 11 … … n1Indicating n belonging to a first operator1The number of each seed; profile info 2 indicates second operator resource information, Profile 21 … … n2Indicating n belonging to a second operator2The number of each seed; … …, respectively; profile info N indicates the Nth operator resource information, Profile N1 … … NNIndicating N belonging to the Nth operatorNThe number of each seed; the hash represents a hash digest of the entire shared file. The priority of each operator decreases from top to bottom in sequence.
Fig. 3 is a flowchart of another embodiment of a method for sharing seed code numbers by esims according to the present invention, where the method can be applied to devices in the internet of things. As shown in fig. 3, the method for sharing seed code numbers by esims provided in this embodiment may include:
s301, shared files stored in the Internet of things equipment in advance are obtained, and the shared files comprise a plurality of seed code numbers belonging to a plurality of operators.
The shared file in this embodiment may include seed code numbers of multiple operators, and for example, the shared file shown in table 1 may be used. If the internet of things equipment is used in China, the shared file can comprise seed code numbers belonging to 3 operators of China Mobile, China Unicom and China telecom; if the internet of things device is used globally, the shared file can also include seed code numbers of other country operators so as to provide initialization connection globally.
S302, selecting a seed code number from the seed code numbers belonging to the highest priority operators according to a preset random algorithm.
Since the seed code numbers of the operators having a high priority are preferentially used in accordance with the priorities of the operators, the seed code number of the operator having the highest priority is selected first. Taking the shared file shown in table 1 as an example, if the priority of the Profile info 1 is the highest, it may be determined that a range is [1, n ] according to a preset random algorithm1]So as to derive from n belonging to the first operator1One seed code number to be used is selected from the seed code numbers.
And S303, writing the selected seed code number into an eSIM chip of the Internet of things equipment.
In this embodiment, after the seed code number is selected according to a preset random algorithm, the selected seed code number is written into an eSIM chip of the internet of things device, so as to be used when an initial connection is established with an operator network.
And S304, establishing an initialization connection with the operator network by using the seed code number written in the eSIM chip.
In this embodiment, after the selected seed code number is written in the eSIM chip of the internet of things device, an initialization connection may be established with the operator network using the seed code number written in the eSIM chip. The procedure for establishing an initial connection with the operator network is the same as in the prior art and will not be described here.
S305, judging whether the initialization connection is successfully established with the operator network within a preset time period. If so, finishing the establishing process of the initialization connection; if not, the step S306 is continued.
The value of the preset time period in this embodiment may be determined by counting the time required for successfully establishing the initial connection between a large number of pieces of internet-of-things equipment and the operator network. For example, the time may be set to 5 minutes, and the time is counted from the establishment of the initial connection with the operator network using the seed code number written in the eSIM chip, and if the network cannot be logged in after 5 minutes, it indicates that the establishment of the initial connection has failed, and step S306 is continuously executed.
S306, judging whether a seed code number belonging to the next priority operator exists. If yes, go on to step S307; if not, the establishing process of the initialization connection is finished.
Taking the shared file shown in table 1 as an example, if the seed code number of the first operator is currently used, the seed code number belonging to the next priority operator exists; if the seed code number of the nth operator is currently used, there is no seed code number assigned to the next priority operator.
S307, selecting one seed code number from the seed code numbers belonging to the next priority operator according to a preset random algorithm. Steps S303-S306 are repeated until the initial connection is successfully established with the operator network, or there is no seed number attributed to the next priority operator.
On the basis of the above embodiment, the method for sharing seed code numbers by esims further includes sharing files including a plurality of seed code numbers belonging to a plurality of operators, so that seed code numbers can be shared among a large number of internet of things devices, the number of required seed code numbers is reduced, the utilization rate of seed code numbers is improved, and the establishment of initialization connection is independent of a single operator, when the seed code number of a current operator is unavailable, the seed code number of a next priority operator can be adopted, and stable and reliable initialization connection can be conveniently and quickly provided.
After the initial connection between the internet of things device and the operator network is successfully established, the service data may be received and transmitted only by acquiring the corresponding service code number from the service platform, and therefore, in this embodiment, after the initial connection is successfully established with the operator network, the method may further include: acquiring a service code number, wherein the service code number comprises card data required by receiving and sending service data; writing the acquired service code number into an eSIM chip of the Internet of things equipment; and receiving and transmitting the service data according to the service code number written in the eSIM chip.
A detailed description is given below by using a specific example of how to establish an initialization connection with an operator network and perform transceiving of service data by using the method for sharing seed code numbers by esims provided by the present invention. Fig. 4 is an exemplary diagram of an application of the method for sharing seed code numbers by esims according to the present invention. It should be noted that the operator platform is not shown in fig. 4. The Agent process (Agent) is used for realizing intelligent connection management, and bridging the server and the terminal; a Subscription management Data Preparation server (Subscription Manager Data Preparation +, SMDP for short) is used for preparing a service code number; the Local seed code number Assistant (Local Profile Assistant, abbreviated as LPA) is used for inserting the seed code number and the service code number into the eSIM; the Shared Profile includes a plurality of seed number of a plurality of operators.
As shown in fig. 4, a virtual card factory (VMC) generates a shared file. The operator included in the shared file can be determined according to the use area of the internet of things equipment, and the number of the included seed code numbers can be determined according to the number of the internet of things equipment using the shared file. Before the equipment of the Internet of things leaves a factory, the Shared Profile, the Agent and the LPA are integrated into firmware of the equipment of the Internet of things. When the Internet of things equipment is started, the Agent analyzes a Shared Profile file to obtain a seed code number Profile, the Agent inserts the obtained Profile into the eSIM through the LPA, the Internet of things equipment uses the newly inserted Profile to register a network, and the Agent sets an Access Point Name (APN) and establishes an initialization connection with an operator network. If the acquired Profile cannot be accessed to the network for 5 minutes due to network coverage and the like, the Agent selects the Profile of the next priority operator to try continuously until success or no other available seed code numbers exist.
After the initial connection is successfully established with the operator network, the service platform generates a service code number and then sends the service code number to the SMDP +. The Agent connection service platform obtains a service Activation Code (AC for short) and provides the service Activation Code to the LPA, and the LPA uses the service AC to download a service Code number through the SMDP +. And the Internet of things equipment receives and transmits the service receipt by using the service code number.
The internet of things device in this example may be a translator, for example. When the translator is transferred from one country to another country, after the other country falls to the ground, the previous service code number is unusable, a seed code number is randomly selected from seed code numbers of the first priority in the Shared Profile to establish initial connection with the operator network, and if the login is unsuccessful within 5 minutes, a seed code number is randomly selected from seed code numbers of the next priority to establish initial connection with the operator network until the login is successful. And after the network is successfully logged on, the local service code number is continuously issued through the service platform.
An embodiment of the present invention further provides a device for sharing seed code numbers by esims, please refer to fig. 5, where the device 50 for sharing seed code numbers by esims provided in this embodiment may include: an obtaining module 501, a selecting module 502, a writing module 503 and a connecting module 504.
