Product Description

IMS (IP Multimedia Subsystem) is an IP Multimedia Subsystem, a novel form of multimedia service that caters to the needs of the multimedia services under the 5G system, particularly for VONR services.

The IMS equipment serves as the multimedia service function for the 5G network, primarily responsible for functions such as authentication management, session management, routing, service triggering, and network interworking. It includes network elements such as I-CSCF, S-CSCF, P-CSCF/LRF, BSF/NAF, BGCF, HSS, MRF, MGCF/MGW, and ENUM/DNS. Utilizing a separate architecture design, it allows for the separation of network functions, enabling the construction of the network in a software-based, modular, and service-oriented manner. This enhances the flexibility of device deployment and improves system performance.
