Abstract: PURPOSE: A data coincident method between a VLR(Visitor Location Register) and an HLR(Home Location Register) of a mobile communication network is provided to receive a normal communication service by selectively performing a re-location register of a subscriber of an abnormal primary HLR to a secondary HLR in a VLR and coinciding with location information of a mobile communication subscriber between secondary HLRs in the VLR. CONSTITUTION: An AP(Application Part) of an MSC/VLR adds a certain attribute for storing a signal point of an HLR in a subscriber database. A primary HLR stores a signal point of a primary HLR in a database of a subscriber stored in a VLR. A switching is generated to the secondary HLR when performing an abnormal state of the primary HLR or a link inactivation of the primary HLR, and a secondary HLR transmits a URDD(Unreliable Roamer Data Directive) message to the MSC/VLR. The MSC/VLR receives the URDD message, searches a signal point database of an SCCP(Signaling Connection Control Part) using the signal point of the HLR, and extracts the signal point of the primary HLR and the secondary HLR. A confirm flag(D_CONFIRM_FLAG) is changed into a true for informing that a re-location register is needed to a subscriber having a signal point to be coincided with the signal point of the primary HLR and the secondary HLR in the database of the subscriber stored in the MSC/VLR. Instructions are successively transmitted to a base station for changing system parameters of the base station to compulsorily perform a location register of subscribers for roaming to the base station. All subscribers of the base station for receiving the instructions transmit a location register message to the base station. The transmitted message is transmitted to the MSC/VLR. The MSC/VLR receives the location register message performs a location register of a subscriber set as a not-HLR confirm(NOT-HLR-CONFIRM) to the second HLR and neglects the location register message of residual subscribers.

Then, the gauge indicates the engine torque. The engine control unit compares battery voltage with a predetermined voltage and compares an engine RPM(revolution per minute) with a predetermined engine RPM. When the battery voltage is more than the predetermined voltage and the engine RPM is more than the predetermined engine RPM, the engine control unit outputs the engine torque. Further, the system decides if data are transmitted through the can communication line. If not, the system stores a trouble code and finishes all processes.
