the first is to send and store:
in this mode, the camera first sends the captured video stream in real time to a designated server or client. This approach is commonly used for real-time monitoring or video telephony.
If the storage function is configured, the video stream may be saved to a local storage device (e.g., SD card) or a remote storage server at the same time as or after transmission.

This approach is often used for scenes that do not need to be viewed in real time, such as security cameras that only view when motion is detected.
This approach has the advantage that the use of network bandwidth may be reduced, but may increase the local storage requirements.

eSIM (embedded SIM card) is a virtual SIM card technology, which is embedded in a device in a software form, unlike a conventional physical SIM card. The eSIM mainly handles identity verification with operators, and configuration files of different operators are stored in the eSIM. These profiles contain authentication information and parameters related to the particular operator network. The device uses the authentication information on the eSIM to access a particular carrier network, which is determined based on the profiles stored on the eSIM, which are associated with the particular carrier. When the multi-network scheduling camera based on the eSIM technology selects one operator, the corresponding configuration file is downloaded and stored on the eSIM. This profile contains all the necessary information to enable the device to access and communicate over the carrier's network. Unlike traditional SIM cards, esims can be configured remotely, allowing users to switch operators without changing the physical SIM card. The eSIM stores and manages information related to mobile communications, which may be contained in the eSIM, and in the aspects herein, can exist in either a configuration file or a block of information in the eSIM:
1) IMSI (international mobile subscriber identity): this is a unique identification code for identifying the user in the mobile network. It is similar to the IMSI on a conventional SIM card. The IMSI is identity information of the mobile device, which is used for authentication and communication between the device and the operator network, and the IMSI is used for establishing and maintaining a mobile communication connection, including authentication and identifying the operator network to which the user belongs. The IMSI is typically composed of 15 digits, including a country code, a network identification code, and a subscriber identification code.
2) ICCID (integrated circuit card identification code): ICCID is used to identify and identify eSIM cards, which is a unique identification code that is used to identify and distinguish between different eSIM cards. ICCID is typically comprised of 19 digits, including card type identification, issuer identification, personal account identification, and the like. It is similar to the ICCID on a conventional SIM card. The ICCID is not used for direct communication between the device and the carrier network, but is used to uniquely identify the eSIM card itself. ICCID on eSIM cards typically consist of numbers, similar to the card numbers on traditional physical SIM cards. The main functions of the device are as follows:
activation and management: ICCID is typically associated with the activation and management process of eSIM cards. An operator or service provider can use the ICCID to manage the state and configuration of eSIM cards.
Identifying an operator: a portion of the information of the ICCID may contain information about the operator to which the eSIM card belongs, but this is not its primary purpose. It is mainly used for unique identification of eSIM cards.
When a user selects a particular carrier or profile on a device, the eSIM card uses more detailed information stored in the profile to identify and connect to the carrier's network. ICCID is primarily used to identify eSIM cards, rather than directly for communication between devices and networks.
3) Key and authentication information: the eSIM can contain keys for authenticating and encrypting communications to ensure the security of the communications.
4) Operator configuration information: the eSIM contains configuration information, including APN (access point name), network code, etc., required to connect to a particular mobile operator network.
5) Personal data: the eSIM may contain user personal information such as name, address, etc. This information is sometimes used to verify the identity of the user at the time of activation.
6) Network configuration file: the eSIM can store multiple network profiles so that users can easily switch between different operators.
7) Country code and operator identification: this information helps the device identify and connect to the correct carrier network.
8) Short message center number: and the center number is used for sending and receiving the short messages.
9) Network functions and service subscriptions: the eSIM can store mobile service subscription information for the user, such as data plans, voice calls, text messages, and the like.
In summary, esims contain various information needed to connect to the mobile network and communicate with the device, which is stored in digital form on a chip and updated and configured as needed. Note that different devices and operators may store different types of information in esims, and thus the specific content may vary.
The network scheduling system is an automatic operation system in the whole camera monitoring process, and in the operation process, a corresponding network protocol is executed, and because of different network states corresponding to different cameras, operation time parameters of different network scheduling protocols are generated, namely, the network scheduling system adopts information in an eSIM card of the Internet of things, network real-time conditions, an alternative link set and network characteristic information of an operator as input information to operate the network scheduling protocol.
When the camera transmits information, the operator is selected and the network protocol is signed according to the network test result, so that the camera is ensured to work under an optimal network condition.
The network scheduling system carries out the innovative method of network intelligent scheduling based on the content of the eSIM card:
dynamic authentication and authorization:
dynamic identity verification is performed using the IMSI, ICCID, and key in the eSIM. When a device attempts to connect to the network, it can authenticate based on information in its eSIM, ensuring that only legitimate devices can access.
And allocating proper network resources and rights, such as data transmission speed, bandwidth and the like, for the user according to the personal data of the user and the service subscription information.
Specifically, the method comprises the following steps:
first, based on user profile and service subscription information:
the network service provider authorizes according to the registration information of the users and the service types subscribed by the users;
second, network resources and permissions are allocated:
