13 Restoration of Data in an LMU

03.073GPPRestoration proceduresTS

When an LMU restarts following a failure, it shall reinitialize all data concerning LCS measurement and O&M tasks to indicate that no tasks ordered by an SMLC are active. A Type A LMU shall then perform an “IMSI Attach”. A Type A LMU shall then open a signalling connection to its controlling SMLC as described in GSM 03.71. Both a Type A LMU and a Type B LMU shall send an LLP Status Update message to their controlling SMLC containing an indication that the LMU has restarted following a failure. The SMLC shall update its data regarding the state of the LMU and shall return an LLP Update Status acknowledgment to the LMU.
