Abstract: Systems and methods are described for allocating frequency resources based on historical usage data in a wireless communication system. A base station tracks its local usage pattern to generate a set of historical usage statistics. The base station may share those statistics with another base station node in the same network and with a server. The server may generate a frequency resource allocation plan to allocate shared resources most efficiently to various base stations based on historical usage information. Allocating frequency resources in this manner reduces the probability of cochannel interference between nearby cells and optimizes power solutions for local and regional radio access networks.

Abstract: A wireless base station and method are described for adjusting an output power level for self-optimizing radio access node. The base station monitors a link metric of a downlink traffic channel and records the measurements as historical link metric data. Later, the base station compares the link metric with the historical link metric data and adjusts the power level of a broadcast channel and one or more system channels. This may reduce the operating radius of the base station, including the broadcast channels, system channels, and traffic channels, to reduce interference with other cells in a network. This method may be used in a femtocell or picocell wireless base station.

Abstract: A networked computing system that is configured to optimize short-range wireless communications within a distributed wireless communications network. The networked computing system may include one or more base stations, a transceiver device having shorter range wireless communications capability than the base station(s), and one or more user equipment capable of communicating with the transceiver device and the base station(s). Within the networked computing system, the transceiver device is configured to: transmit a signal to detect a regional base station and then determine at least one operating parameter based on communications characteristics associated with the detected regional base station(s). The operating parameter(s) may be a non-interfering operating power levels or a modulation and coding scheme level utilized to facilitate communications between the transceiver device and the user equipment.

Abstract: A wireless communications system includes a radio resource manager, one or more base stations, and one or more wireless transceivers capable of communicating with the base stations. The wireless transceivers are configured to be able to measure the difference in network parameter (e.g. frequency and timing offset) between base stations within their range. These network parameter differences along with other information is communicated to the radio resource manager which is then able to update or correct the signal or signals of one or more base stations using the information from the wireless transceivers.

Abstract: A networked computing system facilitating ancillary device measurement of regional network communications in order to determine intra-network communications handovers. The networked computing system includes a base station, one or more transceiver devices having shorter-range communications capability than the base station, user equipment, and a data communications network facilitating data communications amongst the networked computing systems devices. Within the network, a first transceiver device may be configured to detect ancillary communications between a user equipment and the base station, and then measure one or more characteristics associated with the ancillary communications in response to detecting the ancillary communications. The first transceiver device may also be configured to transmit the measured characteristics to the base station or to an auxiliary network controller device that is capable of making network communications usage decisions based on one or more network resource usage rules.

Abstract: Systems and methods are described for segregating airlink resources in a wireless communication network by traffic type. When voice data and traffic data are sent simultaneously in a wireless network using a limited set of frequency resources, the data traffic can cause unacceptable interference in the voice traffic. Accordingly, transceivers share their voice traffic and data traffic demands and may allocate portions of an airlink resource into resource zones for exclusive use by voice traffic and data traffic. Within each resource zone, the transmission can be optimally managed for each traffic type, and interference between voice traffic and data traffic is reduced.

Abstract: A networked computing system including multiple network base stations, user equipment, a network resource controller (NRC), and a data communications network facilitating communications amongst all devices of the networked computing system. The NRC determines a current radio channel available capacity based on a user load associated with regional user equipment, and then forecasts a maximum radio channel capacity based on the current radio channel available capacity. The NRC may be a network base station and it may determine a number of additional user equipment it can support as a component of the forecast maximum radio channel capacity. The NRC/base station may be further configured to determine a handover threshold utilizing the forecast maximum radio channel capacity, and when the NRC base station's number of users exceeds the handover threshold, one or more user equipment may be handed over to a second network base station with better service capacity.

Abstract: A networked computing system including multiple network base stations, user equipment, and a data communications network facilitating communications amongst all devices of the networked computing system. The radio frequency isolation between two network base stations is determined by taking measurements of a radio operating parameter associated with at least one interference source. A regional network device located near one of the two base stations is configured measures the radio operating parameter on a periodic basis and then transfers the measurements to a radio communications controller. The radio communications controller then allocates network communications resources to user equipment, and optionally designates radio operation levels for one or more network base stations, based on a comparison of the received measurements to known broadcast levels of the radio operating parameter.

Abstract: A networked computing system, including multiple radio access nodes (RANs), multiple radio communications controllers (RCCs), and a data communications network facilitating communications amongst the RANs and the RCCs of the system. A regional RAN receives a default eMIB associated with a first type of RAN (e.g., a macrocell, microcell, picocells, or femtocell RAN types) from a RCC, in response to a registration event of a RAN initialization process. The regional RAN maintains a dynamic eMIB comprising network operating parameters determined by various self-optimization processes. The network operating parameters of the dynamic eMIB are selected to fall within a range designated by the default eMIB. During a network failure condition, the regional RAN is configured to use a temporary eMIB comprising failure level operating parameters in order to mitigate network deficiencies caused by the network failure condition.

Abstract: Systems and methods are described for reducing an interference level associated with frequency drift in a wireless base station. The base station monitors an interference level in a frequency resource caused by a first frequency resource colliding with a second frequency resource. If the interference level is outside of an expected range, the base station adjusts a parameter of the base station such as a reference oscillator frequency to compensate for frequency drift. This method may be used in a femtocell wireless base station.
