Unified communication system based on micro base station

A unified communication system based on micro base station, comprising:

• a micro base station subsystem, a landline telephone network subsystem, an office network subsystem and a communication switching subsystem, wherein the micro base station subsystem, the landline telephone network subsystem, the office network subsystem are connected with the communication switching subsystem respectively;
• the micro base station subsystem is configured to receive a voice service request from a mobile terminal, and send the voice service request to the communication switching subsystem;
• receive a voice service request from the communication switching subsystem, and send the voice service request from the communication switching subsystem to a mobile terminal corresponding to identification information of a called user in the voice service request;
• the landline telephone network subsystem is configured to receive a voice service request from a landline telephone terminal or a Public Switching Telephone Network (PSTN), and send the voice service request to the communication switching subsystem when a called user in the voice service request is a mobile communication user;
• receive a voice service request from the communication switching subsystem, connect to an intranet landline telephone terminal corresponding to identification information of a called user in the voice service request when the called user in the voice service request is an intranet landline telephone user, or send the voice service request to the PSTN when the called user in the voice service request is an extranet landline telephone user;
• the office network subsystem is configured to receive a service request from the communication switching subsystem, and when the service request is an office service request, process an office service, or when the service request is a data service request, send the data service request to the Internet;
• the communication switching subsystem is configured to receive a voice service request from the micro base station subsystem and the landline telephone network subsystem, send 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, or send 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, wherein landline telephone network users comprise intranet landline telephone users and extranet landline telephone users, mobile communication users comprise mobile communication intranet users;
• receive a service request from the micro base station subsystem, and send the service request to the office network subsystem.
