Abstract
Location-based calling may be provided for callers that connect to a wireless network using femtocells. A network device may receive a call initiation message including an identifier of a femtocell through which the call was placed. The network device may obtain an identifier of a macro cell base station that serves a geographical coverage area that includes the femtocell and replace the identifier of the femtocell, in the message, with the identifier of the macro cell base station, to obtain a modified message. The modified message may be forwarded through the network to be processed as if the caller placed the location-based call through the macro cell base station.
