Multimodal Data Fusion in IP Multimedia Subsystem: Analysis for Stability

The IP Multimedia Subsystem (IMS) is a telecommunications architecture that delivers multimedia services over 4G and 5G networks. In the absence of IMS, users are unable to access high-definition voice calls and other advanced features, such as video ringback tones and conference calling. Given its critical role, IMS must operate continuously to ensure uninterrupted service availability. Moreover, any malfunction within the system can result in significant revenue loss and decreased productivity. Consequently, operations and maintenance activities are of paramount importance, necessitating effective methods for identifying and diagnosing system anomalies. This manuscript proposes a solution based on multimodal data fusion, designed to assist network administrators in both detecting anomalies and analyzing network performance within the IMS environment.
