Wireline and wireless operators around the world are embracing the IMS (IP Multimedia Subsystems) architecture. This functional framework is the ultimate means to significantly reduce operating expenses, while gaining the flexibility needed to smoothly introduce new customized subscriber-centric services.
IMS provides the framework for a common application and session control layer standardized on IP, with SIP controlling all media sessions.
Disaggregating the transport, control, and application functions of the service layer from the access network enables the transmission of any type of media (i.e., voice, video or data) using any type of access method (e.g., DSL, cable, FTTx, LTE, 3G mobile).
All call and application signaling takes the same paths, allowing a maximum convergence of services. The IMS standardization breaks down all the functions necessary to support multimedia applications and to provide standardized (open) interfaces towards application servers enabling enhanced premium services as well as the interworking with other (legacy) networks such as the PSTN/PLMN
From a network operations perspective, deploying, setting up trials, or even just experimenting with IMS constitutes a huge leap in complexity. The operator therefore finds that deploying a monitoring solution for IMS is indispensable. RADCOM's Omni-Q Service Assurance system meets all the IMS monitoring challenges.
IMS signaling flows are highly complex. This means that more network element functions are involved in establishing calls, and that signaling traffic volume is significantly larger. Establishing an end-to-end call/session is a prerequisite for any meaningful network visibility, troubleshooting, or tracing of customer complaints
RADCOM’s Omni-Q Service Assurance system provides a comprehensive solution that meets all the challenges that IMS service providers face when delivering IMS services.
