Problems solved by technology

However, if the certificate in MCIM is invalid or expired, and SHO does not update and download a new certificate in time before the invalidation or expiration, or if the existing MCIM fails, M2ME will lose contact with SHO, resulting in service interruption; another On the one hand, M2ME faces the potential to change the operator's ownership. It is possible that the original MCIM may not work properly before the new MCIM is downloaded, which will also affect the normal operation of the system.
Generally speaking, due to reasons such as cost and size, M2ME usually does not have a man-machine interface, and the software, hardware and interfaces are relatively simple. Therefore, it is relatively difficult to interact and operate with M2ME

Embodiment Construction

[0026] The basic idea of ​​the present invention is: when the connection between the M2ME and the home operator is interrupted (such as MCIM failure or replacement of the operator), the M2ME re-uses the PCID to initially attach to the home operator, and then obtains the information from the current home operator. The corresponding instruction downloads or repairs the MCIM to the M2ME, so as to obtain the latest MCIM and restore the connection between the M2ME and the home operator.

[0027] It should be noted that, in order for M2ME to contact the operator and use the network service provided by the operator, the operator first needs to provide MCIM to the M2ME. The provision process includes three stages: initial attachment, discovery and registration, and MCIM application provision.

[0028] For TRE-based M2ME, the PCID is pre-programmed and embedded in each wireless M2ME. The PCID can be used for initial access to a wireless network so that "permanent" user credentials, such...

Abstract

A method for self-manage of Machine to Machine equipment (M2ME) is provided by the present invention, which includes: after the connection between the Machine to Machine Equipment (M2ME) and the Selected Home Operator (SHO) is broken off, said M2ME initially attaches to the registration operator (RO) with the Provisional Connectivity Identity (PCID); said RO downloads a Machine Communication Identity Module (MCIM) to the M2ME or repairs the MCIM to the M2ME; Said M2ME establishes connection with the SHO according to the downloaded or repaired MCIM. A system for self-manage of Machine to Machine equipment (M2ME) is also provided by the present invention. With the present invention, the M2ME can resume the broken connection with the SHO automatically and in time, therefore the stability of the system can be improved.

Description

technical field [0001] The present invention relates to a machine-to-machine (M2M) communication technology, and in particular to a method and system for machine-to-machine self-management. Background technique [0002] The M2M communication technology enables the deployment of wireless devices without human intervention, and wireless M2M devices (M2M Equipment, M2ME) are widely deployed in telemetry and remote sensing applications, such as system monitoring, remote vending, goods management and other fields. [0003] One challenge in deploying M2ME is how to efficiently deliver M2ME remotely. A traditional wireless device is implemented through a Universal Subscriber Identity Module (USIM). The USIM is an application provided by a wireless network operator and installed on a UICC card. However, in some cases it is impractical or impossible to insert a UICC card in M2ME. Therefore, in existing research, TRE (Trusted Environment) can be integrated in M2ME, TRE has no physic...
