Description

Internet of things aerial card writing method, auxiliary method, device and communication equipment

Technical Field

The invention relates to the technical field of communication, in particular to an Internet of things air card writing method, an auxiliary method, an apparatus and communication equipment.

Background

With the widespread application of narrowband Band Internet of Things (NB-IoT), NB-IoT terminals (UE) are widely used in various industries. An embedded internet of things card (eUICC card) is used as an authentication tool for accessing a terminal to an operator network and a security carrier for bearing various applications and data, and becomes a preferred mode of a cellular internet of things terminal. More and more standard terminal products integrated by a machine and a card are adopted, and the stability and the safety of mobile communication connection are ensured by adopting an embedded card. However, since the embedded internet of things card is fixed in the terminal and cannot be replaced at will, the number management, number configuration and number recovery of the embedded internet of things card are important tests faced by operators. The embedded internet of things card carries a special temporary code resource when leaving a factory, and is subsequently required to be replaced by a formal code according to the signing time of a user. At present, on NB-IoT (Internet of things-IoT) equipment, the replacement of a temporary code number to a formal code number is completed by adopting an over-the-air card (OTA).

Currently, there are two main ways for an in-air card (OTA): one is a short message-based Bearer mode, and the other is a Bearer mode based on a Bearer Independent Protocol (BIP). The current in-air card opening process comprises the following steps: after the terminal equipment is accessed to the wireless network, the card writing platform is informed of the triggering information, then the card writing platform automatically issues a card writing short message or a BIP instruction, and the terminal completes the process of changing the temporary code number to the formal code number according to the short message or the BIP instruction.

The existing NB-IoT device over-the-air card-opening scheme has the following problems:

the NB-IoT equipment cannot be actively paged by a network, and the card-opening platform only knows the message of the current equipment accessing the network and cannot continuously know the real-time state of the current equipment. For example, after a Short Messaging Service (SMS) message is sent, it cannot be guaranteed that the message is sent to a terminal, and meanwhile, the status and result of the card cannot be accurately known.

The NB-IoT device is set to a Power Saving Mode (PSM), and after the card writing short message is issued, the device may go to a sleep state, in which case the card writing operation may not be completed, and the sleep may cause the card writing failure.

3. Because the accurate real-time state of the NB-IoT equipment cannot be known, the card writing platform can issue repeated card writing messages for many times after not receiving a card writing reply, and network signaling resources are wasted.

4. Batch equipment simultaneously requests card writing with the card opening platform, and the access capability is limited under the conditions of the same cell and the like, so that a large number of card opening instructions are congested, and further card writing failure is caused.
