摘要： A radio access network (RAN) may determine that a quality-of-service (QOS) load of a first base station exceeds a QOS load high threshold. The RAN may further determine that a set of wireless communication devices (WCDs) served by the first base station are located within a geographic area nearby a second base station. The RAN may additionally determine that the set of WCDs are responsible for at least a predefined portion of the QOS load of the first base station, and may power on the second base station. If at some point a second QOS load of the second base station falls below a QOS load low threshold, the RAN may facilitate handover of at least one of the WCDs served by the second base station from the second base station to the first base station, and may power off the second base station.

摘要： Systems and methods of operating multimode 3G/4G communications devices in an overlapping 3G/4G coverage area (e.g., WiMAX or LTE/CDMA-EvDO) include determining a loading condition of the 3G and 4G base stations. If the 3G and 4G base stations are lightly loaded, one or more 4G Channel Quality Indicators (CQI) are compared with one or more corresponding 3G Data Rate Control (DRC) indices to determine which of the 3G and 4G networks allows a higher data throughput. The dual mode communications device is handed off to a 4G base station associated with the 4G coverage if the 4G network allows the higher data throughput; otherwise, the dual mode communications device is handed off to a 3G base station. User priorities, application categories, and/or MIMO and diversity modes may be used to determine handoff if the base stations are more than lightly loaded.

摘要： Exemplary methods and systems may generally be implemented to allow a macro-network base station without access to a GPS reference signal to provide some or all of the functionality for which existing macro-network base stations typically rely on GPS. In a first aspect, an exemplary macro-network base station may determine its location using a location-determination technique that is based upon the angles of arrival of FM radio signals from nearby FM stations. In a second aspect, an exemplary macro-network base station may stabilize its local oscillator by phase-locking its local oscillator to an FM radio signal, and periodically adjusting its local oscillator to account for phase drift of the FM radio signal. And in a third aspect, an exemplary macro-network base station may synchronize its frame-start timing with a nearby base station using a frame-start timing signal that the base station has synchronized to frame transmissions from the nearby base station during a setup routine.

摘要： A centralized security management system (CSMS) is provided to monitor a network to detect and mitigate attacks in or to the network. The CSMS includes a variety of devices located throughout the network to collect and synthesize data collected or obtained from devices operating in the network. The collected data is analyzed using behavioral engines or other software algorithms to develop trends for a normal and abnormal operating condition. The abnormal operating conditions are analyzed further to determine attacks to the devices or the network. Based on the attacks, a mitigation scheme is implemented to remove or reduce the attacks.

摘要： In one or more embodiments, a system and method of managing network channel quality in a wireless communications network includes reporting a channel quality measurement from the particular user to a base station (BS) over an available CQICH, and determining a MCS based, at least in part, upon the channel quality measurement. If a threshold network CQICH capacity is reached during a subsequent data frame such that a CQICH is no longer available, MAC level messages are generated between the BS and the particular user to trigger reporting of signal quality information to the BS by the particular user. After the next CQICH cycle commences and if a CQICH is still unavailable, the signal quality information is continued to be provided via MAC level messages. Otherwise, a CQICH is reallocated for a particular user and channel quality measurement reporting is transitioned back to the CQICH.

摘要： A system and method for adaptive control of an averaging parameter in a communications network may include an averaging parameter adaptive control module (APAC) that is associated with a base station and that includes one or more processors configured to generate a first averaging parameter that is transmitted by the base station to a mobile station communicating with the base station. The mobile station may use the first averaging parameter to generate first channel condition information that indicates a condition of a communication channel. First feedback information including the first channel condition information may be received at the base station. The APAC may generate a second averaging parameter using the first averaging parameter and the first feedback information and may transmit the second averaging parameter from the base station to the mobile station, thereby adaptively controlling the second averaging parameter based on the first feedback information.
