SWITCHING METHOD FOR SWITCHING WHEN ERRORS OCCUR ON NETWORK OF MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A switching method when errors occur on a network of a mobile communication system is provided to suspend a connection of a wrong path when a network path is connected with other computer, and to perform a re-connection of a normal path, so that communications may be capable regardless of the errors. CONSTITUTION: A check process waits for an access from a process for no path testing performances. If a process requests an access, the check process allows the access to the requesting process. If the process does not request the access, the check process carries out the path testing performances. If communication path errors do not occur, the check process does the proper performances. If the communication path errors occur, the check process notifies all accessed processes of error generations. If communication errors occur in a used communication path, the check process carries out a switching performance in other path. Processes for no path testing performances are accessed to a path testing function process. The Processes do the proper performances with other computer and wait for receiving a path error message. When the processes notify the error generations, the check process performs the switching function to other path.
