Chunghwa Telecom in Taiwan has the most PSTN (Public Switched Telephone Network) coverage, which contains a large number of SS7(Signaling System No. 7) signal data available for research and analysis, not only for the communication problem and abnormal communication pattern detection, but also for the development of related applications. In the past, without an OSS (Open Source Cloud) Platform, whether utilize relational databases or Memory Disk there was no effective solution to the massive data for the Call Data Collection and Analysis. Therefore, with the mature of OSS technologies, the HBase/Hadoop technology is capable to solve the problem. We propose an approach to collect the 110/119 call signals, and build a collection capability on an OSS Platform. Based on the OSS Platform, the cost of equipment can be reduced and the flexibility and scalability of the system can be increased.Through the multitasking mass data processing and analyzing feature based on the Open Source Cloud Platform, quick user queries and system fault tolerance can be achieved.
