According to one aspect of the teachings herein, a Network Services Capability Layer or NSCL is configured to initiate failure recovery responsive to detecting an abnormal reset at the NSCL. Failure recovery operations exploit recovery information that is maintained by the NSCL in a persistent data store during normal operation, e.g., on an ongoing basis, in real-time as new M2M registrations or other M2M information changes occur at the NSCL. Such operations advantageously permit the NSCL to recover missing or corrupted information after the abnormal reset, from M2M entities identified from the recovery information. |

1. A method of failure recovery for a Network Services Capability Layer, NSCL, in a Machine-to-Machine, M2M, network, said method comprising:
safeguarding M2M resource information at the NSCL, by dynamically maintaining recovery information in a persistent data store, to include identifiers and Point-of-Contact, POC, information for those M2M entities associated with the M2M resource information; and triggering a failure recovery process responsive to detecting an abnormal reset at the NSCL, wherein said failure recovery process includes recovering missing information based on:
retrieving the recovery information from the persistent data store;evaluating the M2M resource information as existing at the NSCL after the abnormal reset with respect to the recovery information, to identify missing M2M resource information; andcontacting those M2M entities indicated by the recovery information as being associated with the missing M2M resource information, to recreate the missing M2M resource information at the NSCL. |
