SOA-Based Alarm Integration for Multi-Technology Network Fault Management

In order for the service provider to offer better quality of telecom services to customers, one of the possible ways is to monitor and control all kinds of deployed network resources, which are used to support the operation of these services, and to proactively analyze and recover any trouble reported from the network resources. In this study, two system integration scenarios along with the associated interface specifications for multi-technology resource alarm notification and retrieval services have been described. An NGOSS-based development methodology was followed, and a number of useful commercials tools were introduced to facilitate the evolution and transformation of legacy BSS/OSS, so that these BSS/OSS are able to support loosely-coupled interoperability by using standards-based interfaces based on the service-oriented architecture. The functionalities of multi-technology network fault management were realized by means of JMS and Web Service techniques. The implementation described in this paper shows the feasibility of the proposed development methodology.
