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 (BSSs). 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 MSC/VLR, 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.
