Backhaul Network Optimization Solutions for 2G and 3G Mobile Networks

Dialogic® I-Gate® 4000 SBO-MB (Session Bandwidth Optimizer-Mobile Backhaul)

The Dialogic® I-Gate® 4000 Session Bandwidth Optimizer Mobile Backhaul is a standalone system that can optimize bandwidth and increase bandwidth capacity significantly in the backhaul segments of both 2G and 3G mobile networks. Because it optimizes Abis and Iub data streams, including both ATM and IP-based Iub streams, the I-Gate 4000 SBO MB can provide a cost-effective and efficient strategy for increasing backhaul capacity, resulting in significantly reduced capital and operation expenses. The I-Gate 4000 SBO MB can also accept native IP and PCM streams and transmit the combined optimized stream over TDM and/or IP.

Along with Abis and Iub optimization, the I-Gate 4000 SBO MB leverages statistical multiplexing and grooming techniques developed by Dialogic that have been shown in field trials to typically double the capacity of backhaul links while preserving the quality and integrity of the original data traffic through Quality of Service (QoS) protection techniques.

Value propositions and applications:

Instantly increase the capacity on mobile backhaul through optimization of Abis and Iub traffic between BTSs/BSCs and NodeBs/RNCs allowing more users with lower call drop rate and maintain the voice quality.  This solution is perfect to solve congestion in areas with sudden increase in the total number of users.
