PURPOSE: An application layer self-diagnosis apparatus and method in a home location register(HLR) is provided to save the maintenance cost and improve the reliability to the system by storing messages processed in the application layer of the HLR in a shared memory and displaying the messages to perform the self-diagnosis. CONSTITUTION: If an operator inputs self-diagnosis items, a previous day received message storage, and a current time in a MAP and sets a program environment for self-diagnosing a TCAP and the MAP(S100), a monitoring process judges whether messages transmitted from the MAP and the TCAP are received in a shared memory(S200). If the messages transmitted from the MAP and the TCAP are received in the shared memory, the monitoring process checks a time in which message are received(S300). If the monitoring process judges whether the current time is identical to the time in which messages are received(S400). If the current time is identical to the time in which messages are received, the monitoring process stores a current received message(S500). The monitoring process judges whether a data quantity received in the current time or the previous time is more than the self-diagnosis items(S600). If the data quantity received in the current time or the previous time is less than the self-diagnosis items, a display unit displays messages stored in the monitoring process to show the messages to the operator(S700). If the current time is not identical to the time in which messages are received, messages received in the previous time are stored(S410). If the data quantity received in the current time or the previous time is more than the self-diagnosis items, the messages stored in the shared memory are cleared for stably driving a system(S420).
