How to deal with failures in on-line increase / decrease in CDM system

摘要

The present invention relates to the operation of a Code Division Multipule Access (CDMA) base station system, and more particularly, to a method of processing fault data for hardware changes and software changes when a system is expanded or reduced without interrupting a service.;One preferred embodiment of the present invention is a base station manager in a method of implementing a failure handling function for hardware changes and software changes of a system generated during on-line increase / decrease in a CDMA system. A first step of determining whether or not a file exists for database files necessary for troubleshooting when a failure processing block located at) is first survived as a permanent process; A second step of creating a new database file if there are no files to be created as a result of the first step; A third step of performing an initialization operation on each of the data; A fourth step of performing an initialization operation based on the current shape information in a database using an internal memory for hardware shape information as a result of the first step process; A fifth step of the operator performing the operation using the increase / reduction-related MMC when performing the system increase / decrease operation at the request of the operator after the fourth step process; When the configuration management block is normally terminated with the base station resource management block when the system on-line increase / decrease is performed on the operator requirement as described above, the increase / decrease information on the system is sent to the FLM through the queue inside the BSM. A sixth step of transmitting; A seventh step in which the FLM receives a signal for system increase / decrease from a configuration management block; An eighth step of identifying, by the FLM, the increase / decrease target system after receiving the signal; As a result of the eighth step, in the case of expansion, the ninth step of performing a range check; As a result of the eighth step, in the case of reduced snow, a tenth step of determining whether a system exists in existing shape information; When the system increase / decrease operation is normally performed as a result of the tenth step, the FLM transmits a frequency area, a sector, a selector interface processor (SIP), and a base transceiver for the corresponding device and processor. An eleventh step of acquiring information about the Subsystem (Base Station Controller); A twelfth step of resetting the hardware failure basic data associated with the system changed after the eleventh step and the shape related data for the failure processing for the device and the processor; A thirteenth step of loading the failure processing basic target data according to the hardware change into the hardware failure detection block of the BSC after the twelfth step; In the case of the expansion, reconfiguring shape related data managed by the internal memory database according to the new shape; A fifteenth step of performing a file handling operation for graphic update using a file system to match graphic data with respect to shape-related changes; In the case of a reduction, a sixteenth step of analyzing all failures occurring in the reduction target system and performing a forced failure recovery; And a seventeenth step of reconstructing the shape related data to fit the new shape.
