Abstract: In one embodiment, a wireless system comprises a host MSC/VLR of a public land mobile network (PLMN) and a plurality of base station subsystems (BBSs). Each BSS includes a respective base station controller (BSC) and one or more base transceiver stations (BTSs). The wireless system further comprises a virtual base station controller (VBSC) communicatively coupled to the plurality of BSSs and the host MSC/VLR. The VBSC appears, from the perspective of the host MSCNLR, to be a base station controller for the BTSs in the plurality of BSSs. The VBSC and at least some of the BSSs include functionality for locally switching calls in the BSSs.

Abstract: 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.
