M2M Device Triggering Authorization and Reliability

The patent applies preliminary action by performing authorization checking before device triggering. The network element receives a device triggering authorization request, performs authorization checking based on the request, and only then allows the triggering operation to proceed. This ensures that only authorized devices can be triggered, preventing mistaken triggering of unauthorized devices while maintaining a relatively simple triggering operation flow.

The patent applies the taking out principle by extracting the authorization management function as a separate, independent module within the network element. The authorization checking process is handled by a dedicated authorization management module that receives authorization requests, performs checking, and returns results. This separation allows the core triggering process to remain simple while the authorization function is handled independently, reducing overall process complexity.

The patent applies feedback by implementing a notification mechanism where the network element sends notification messages to the M2M node about the triggering results. The M2M node provides feedback by sending response messages indicating whether the triggering was successful. Based on this feedback, the network element can determine whether to perform retry operations. This feedback loop ensures reliable message delivery while keeping the system operation manageable through automated response handling.
