摘要:
Methods and systems are provided for prioritizing carriers in femtocell frequency-hopping pilot beacons. A femtocell receives registration requests from a number of mobile devices requesting to hand off service from a macro-network carrier to the femtocell. The femtocell identifies the macro-network carrier that each mobile device has handed off from. The femtocell then uses that information to prioritize future broadcasts of its frequency-hopping pilot beacon on those macro-network carriers on which the most mobile devices have handed off from. The prioritization could take the form of broadcasting more often on the higher priority one or more carriers per cycle, or broadcasting for a longer continuous period of time on the higher priority one or more carriers per cycle.

Methods and systems are provided for reducing a number of unauthorized wireless communication devices (WCDs) on a femtocell. A femtocell may initially provide wireless service on a first femtocell carrier. The femtocell may subsequently receive a registration request from a WCD on the first femtocell carrier. The femtocell may then determine whether the WCD is authorized to receive wireless services from the femtocell. Responsive to making a determination that the WCD is not authorized to receive wireless services, the femtocell may switch to providing service on a second femtocell carrier different than the first.

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.

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.

Methods and systems are provided for prioritizing time-division multiplexed communications resources at a femtocell. A femtocell initially provides time-division-multiplexed wireless service to a plurality of wireless communication devices (WCDs) using a first number of slots per cycle, each WCD in the plurality having at least one assigned slot. During the first time period, the femtocell detects a trigger. Responsive to detecting the trigger, the femtocell, in a second time period, switches to providing service using a second number of slots per cycle, the second number being less than the first number, such that a first WCD in the plurality does not have an assigned slot.

Disclosed is a method and corresponding system to help improve inter-frequency handoff. While a radio access network (RAN) is serving one or more devices, the RAN will receive from the device(s) one or more reports of air interface quality on each of a plurality of potential target frequency channels. Dynamically based on the reported air interface quality information, the RAN will then select a given one of the potential target frequency channels to be a preferred target frequency channel. When a given device is fading from coverage, the RAN will then direct the device to scan for coverage on the preferred target frequency channel that was selected based on the earlier reported measures of air interface quality, so as to facilitate inter-frequency handoff.
摘要:
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.
摘要:
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.
摘要:
A method and system for controlling broadcast of system identification. A base station may broadcast in one or more timeslots of a control channel, as a System Identifier (SID) of the base station, a particular SID, but may broadcast in one or more other timeslots of the control channel, as a SID of the base station, a different SID. In addition, when a mobile station registers to be served by the base station, the base station may determine which slot(s) of the control channel the mobile station will monitor and may broadcast in the determined slot(s) a SID that may help to keep the mobile station from transitioning to be served by a different base station.
