A gateway turns encrypted PS data traffic on the Iub interface into clear IP packets so that WAN stream de-duplication and other optimization can be performed to eliminate the transfer of repetitive data across the Iub interface, thereby increasing the throughput between the NodeB and the RNC of the WCDMA network. The gateway pulls PS data traffic out from Iub without disturbing the signaling and CS traffic. The bifurcated PS data traffic is redirected to the GTP I/O port of the gateway where the stream de-duplication is applied. Deployment of the gateway is transparent to the WCDMA network. No network reconfiguration is required to deploy the gateway on the Iub interface.

Optimizing mobile network bandwidth

A communication system comprises a remote optimization server and a central optimization server adapted to communicate with each via a backhaul network. The central optimization server communicates with core network elements for data delivery. The servers provide access to local data servers, manage backhaul links, perform data caching, and optimize transmission of data that needs to be back-hauled in order to reduce data transfer via the backhaul network in a manner which is transparent to users and to core network elements. The servers perform compression and protocol optimization. The remote optimization server comprises a HTTP accelerator which uses client and server side optimization functions to retrieve a bundle of resources associated with a request for base HTML, and maintains a set of persistent connections over which all HTTP traffic is carried.
