TD-SCDMA communication platform based on concept of cloud computing is the natural trend of mobile communication development. Based on introduction of related concept of cloud and TD-SCDMA communication platform, the paper combined TD-SCDMA wireless communication network platform and cloud computing and designed wireless communication network download system under this concept. The communication manage module of system completes signaling transmission, data transmission control and monitoring. The Flash module block manage memory chip. Data block multi-threaded simultaneous downloads, combining with high-level protocol stack module, and the network data backup as well as wireless download transmission was implemented based on concept of cloud computing. System stability and efficiency has been proved in the platform development process.
