The present invention disclosed a unified communication system based on micro base station. The system includes: a micro base station subsystem, a landline telephone network subsystem, an office network subsystem and a communication switching subsystem. The communication switching subsystem receives a voice service request from the micro base station subsystem and the landline telephone network subsystem, sends the voice service request to the micro base station subsystem when a called user in the voice service request is a mobile communication intranet user, sends the voice service request to the landline telephone network subsystem when the called user in the voice service request is a landline telephone network user, receives a service request from the micro base station subsystem, and sends the service request to the office network subsystem.

Unified communication system based on micro base station

Disclosed are a wireless communication system and method and an expansion unit of a flat network architecture. The wireless communication system comprises at least one baseband signal source, an expansion unit (EU) and at least one remote radio unit (RU) connected to the EU. By overlapping the baseband signals output by each baseband signal source, remote transmission and wireless coverage of multimode digital signals are achieved, thereby solving the problem of system performance degradation caused by the interaction of radio-frequency analog signal transmission and optical transmission in the prior art.
