Service Management Center (SMC) is a network-wide video conferencing management system for unified scheduling and management of devices and media resources. It provides users with easy-to-use functions such as conference control and visualized O & M. It also supports face and sign-in data management, live caption, and meeting minutes by interconnecting with the AI server.

Technical Deep Dive

Huawei SMC Large-capacity Edition supports up to 20,000 simultaneous calls within the V2.0 large-scale conferencing architecture. The same platform description refers to as many as one million users and up to 3,000 calls in a single conference under applicable configuration limits. These figures represent separate dimensions: registered user scale, overall concurrent call scale, and per-conference capacity.

Huawei's large-capacity architecture distributes management, call control, and media processing across the appropriate service components. SMC provides conference administration and scheduling, SC handles registration and session control, and MCU resources supply the audio/video processing. Achieving the stated capacity depends on correct deployment sizing, resource pools, networking, licensing, and high-availability design. A system with one million users does not imply one million simultaneous video calls. Presales engineers should collect busy-hour concurrency and conference-size requirements separately. Among the options, the documented simultaneous-call specification is 20,000, answer D.

For presales sizing, the selected signaling platform, media-processing engine, endpoint population and expected peak conference concurrency must be dimensioned independently. Huawei SMC performs centralized administration, Switch Center provides registration and call control, and the MCU supplies the media services needed for multipoint conferencing. The selected software release, server model, licenses and applicable endpoint capabilities determine the actual production limit.
