Methods and systems are disclosed for reducing a number of unauthorized wireless communication devices (WCDs) using a femtocell. A femtocell may transmit a pilot beacon on a macro-network carrier, and may transmit one or more overhead channels on a femtocell carrier. Subsequently, the femtocell may receive a registration request from a WCD. The femtocell may then determine whether the WCD is authorized to receive wireless services from the femtocell, and if it is not so authorized, the femtocell may, during a subsequent slot associated with the unauthorized WCD in a periodically recurring slot cycle, responsively disable at least one of (i) its pilot channel and (ii) one or more of its overhead channels. As a result of the disabling, the unauthorized WCD may move away from the femtocell, perhaps handing off to the macro network.

Femtocell radio access network (RAN) devices are typically small, low-cost base stations that can be deployed in areas where macro-cellular RAN coverage is poor or congested. Thus, wireless communication devices (WCDs) using femtocell devices may benefit from improved wireless coverage, while traffic is offloaded from the macro-cellular RAN. It is desirable to use femtocell devices to their full extent, but also to give the owners of these femtocell devices control over which WCDs may use of femtocell services. Accordingly, femtocell devices may be provisioned with a “greylist” that specifies which WCDs are granted full femtocell services, and which WCDs are granted limited or no femtocell services.

Disclosed is a method and corresponding wireless communication device (WCD) arranged to control how often the device engages in background communication. For example, the WCD may programmatically evaluate a history of transmission power that it has used for transmitting to a serving radio access network. Based on that history of transmission power, the device may then determine how often it should engage in background communications and may set itself to engage in background communications at that determined frequency.

Methods and systems are provided for considering macro-network reverse-link conditions when selecting a power level at which to send an initial access probe to a femtocell. In at least one embodiment, a mobile station receives an indication of macro-network reverse noise, and then selects an initial-access-probe transmit power level based at least in part on the value of the received indication. The mobile station then sends an initial access probe to a femtocell at the selected power level. The mobile station may receive indications of macro-network reverse noise such as a reverse noise rise (RNR), reverse frame error rate (RFER), reverse activity bits (RAB), suggested macro-network initial-access-probe transmit power levels, etc.

A method and system is disclosed for adjusting wireless access coverage based on backhaul capacity. A base station, such as a femtocell, will determine the capacity of its backhaul connection in the downlink direction. The base station will then adjust the power level of it forward link to help ensure that the forward-link data rate to an access terminal is approximately matched to the determined capacity of its backhaul connection. In an example embodiment, the base station will adjust the power level of its pilot until the access terminal is requesting a forward-link data rate commensurate with the downlink rate on the backhaul connection.

Embodiments are described that may help to provide wireless service in a circuit-switched fall back scenario. In particular, when a user entity (UE) falls back from a first network to a second network to conduct a voice call, the first network may instruct the UE to scan a certain predetermined channel or channels for coverage from the second network. However, certain types of base stations typically operate on unlisted channels that differ from the predetermined channels that the UE is instructed to scan. Accordingly, a UE may pre-emptively scan unlisted channels, and report any unlisted channel that is detected to the first network. The first network can then coordinate with the second network to re-provision the base station that was operating on an unlisted channel, to instead operate on one of the predetermined channels that a UE will be instructed to scan during fall back to the second network.
