Software Fault Detection Recovery and Recovery Method in Code Division Multiple Access Mobile System

摘要

The present invention relates to a method and apparatus for detecting / restoring a software fault in a Code Division Multiple Access Mobile System (CMS), and more particularly, The software execution module detects and restores the class and fault according to the operating state of the software in the processor, thereby improving the trueness of the system failure during actual system operation.;In the characteristic configuration, when the wrong data of the received message or the data accessed from the database is abnormal, the library of the sever mor which manages the data related to the operation state of the process is called, A process of moring and repairing a process operation error in which the number of times is stored and a necessary recovery process routine program and a data error recovery routine are called; and a process of collecting information on the current operation status, A process for moring the current state of the current thread, and a process for initializing the process by storing the current state of the thread in the thread level table, and periodically scanning the execution state of each process in the module using the library and comparing the data with data defined in the database Process Operational The process generation status moring process for moring the change of the status and the number of processes that are generated and operating in the execution module are compared with the information of the inputted database by the user to mor whether the range (maximum and minimum value) deviates A process moring process for moring the number of process generations and a process status moring process for periodically communicating a failure of an execution module or a process in the kernel area according to whether a moring message is received within a predetermined time, And a software failure recovery process that sequentially processes a large-scale level of the processor initialization operation from a data initialization operation of a small level according to the degree of the failure and the recovery state thereof.
