The Space-based multi-band Variable Objects Monitor (SVOM) mission is a Chinese-French mission dedicated to the study of the most distant explosions of stars, and gamma-ray bursts. Here, we introduce the real-time response and collaboration system of SVOM, with the adoption of the BeiDou-3 short message communication service. We present the SVOM on-board and on-ground system designs and data flow, together with the collaboration mechanism with other missions. In the first year of the in-flight operation, SVOM has detected 172 gamma-ray bursts, including 147 by the GRM instrument and 62 by the ECLAIRs instrument. At the same time, SVOM has performed 1040 observations, including 122 Target of Opportunity-Exceptional observations, 48 Target of Opportunity-Multi-messenger observations and 870 Target of Opportunity-Nominal observations. All these have increased the scientific output of the mission.
