Design and implementation of channelized data acquisition card for Iub interface in 3G network

In order to achieve real-time monitoring, evaluation and analysis of the Iub interface in 3G network with better use of the existing 3G network resource, it studied and designed a scheme of channelized data acquisition card for Iub interface. Compared to the existing data acquisition cards for Iub interface, the proposed scheme designed a modular channelized data acquisition card, which not only gave a method on STM-1/E1´s multiplexing and de-multiplexing based on the space-division and time-division switching, but also proposed the algorithm of getting IMA group binding information automatically. Practical testing and application results have demonstrated that the designed data acquisition card is of high flexibility and compatibility.
