Abstract:
The described apparatus and methods provide communication services utilizing a combination of non-white space (NWS) and white space (WS) networks. For example, in an aspect, the described apparatus and methods receive, at a first base station (BS) and on a licensed frequency, a communication request for network access from a wireless access terminal (AT). The aspects also determine at least one available unlicensed frequency corresponding to a location of the wireless AT. Further, the aspects partition at least a portion of the network access for the wireless AT to be via the at least one available unlicensed frequency. Additionally, the aspects inform the wireless AT of the at least one available unlicensed frequency for use to obtain at least the portion of the network access. Additional aspects relate to NWS BS assisted handoffs of WS calls, dynamic caching of WS information, peer-to-peer WS communication, and WS BS venue-specific broadcasting.
