Overview
Keyidea central station has a complete satellite system for resources management and reliable hardware and software equipment, all-IP communication, combined with efficient IP acceleration technology to provide users with broadband Multi-point service, the most effective way to provide users with management and monitoring the way of the satellite system works.   Keyidea central station system uses a centralized control management of the CCNM / SCPC system, the networktopology is a combination of star and mesh structure, the central station network control channel broadcast (TDM) and ALOHA channel, the remote site to receive the TDM channel broadcast with network control information, send a message through the ALOHA channel to the central station network, these two methods to achieve and exchange information with the central station. The main function of the network management and control: full DAMA call admission control, channel frequency calibration, the network registration , net log-off , communication timing and system operation monitoring.	KeyIdea central station is modular in design, 5-5000 remote station according to the needs of users, network management, to ensure the user-front investment, easy capacity expansion and upgrading of the Central Station.

Features
Optional network size:	Customized services：
Allows service providers to budget and satellite communications solutions tailored to the needs. Using Keyidea, users can link from several remote sites to the central station, extended to hundreds of thousands of terminals;	According to customer’s demand, Keyidea can not only customize the managing system of central station but also provide user with billing function to meet their own needs, access control, frequency calibration for information channel, the network registration , net log-off,and as well as system-operation monitoring as so on.
Efficient resource utilization：	Manifold business types:：
Can dynamically allocate bandwidth based on customer needs, provide users with as low as 2.4kbps up to 8M high-quality voice or data services, effectively saving the frequency and power resources.
