Claim:
1. A method of deploying small cells in a small cell network in an indoor enterprise space, the method comprising the steps of: locating a plurality of dual identity cells within the indoor enterprise space, the locations providing substantially contiguous radio coverage within selected portions of the indoor enterprise space, each of the dual identity cells among the plurality being configured with dual identities, a first identity of the dual identities being a dedicated PCI (Physical Cell Identity) identity and a second identity of the dual identities being a common PCI identity, each of the dedicated PCI identities exposing a unique PCI to a UE (user equipment) so that the UE may distinguish a cell from neighboring cells, each of the common PCI identities exposing a common PCI to the UE, the common PCI being commonly used by all cells within a detected set, wherein the dedicated PCI identities are functionally disposed in a first layer of a layered network topology and the common PCI identities are functionally disposed in a second layer of a layered network topology, wherein the first layer is operated to localize UE and provide communication service to UEs that are active or relatively insensitive to quality of service and the second layer is operated to provide communication service to UEs that are inactive or are relatively sensitive to quality of service; operating the dedicated PCI identities so that one or more cells in the small cell network that are within listening range of a UE at a given time are identified, identified cells within listening range being members of the detected set, the cells within the detected set being changeable and updated as the UE traverses the small cell network such that different cells come into and out of the listening range of the UE; and configuring the small network so that the dual identity cells may be selectively operated using either or both the dedicated PCI identity and the common PCI identity.
