Abstract: Systems and methods are described for determining a carrier for a wireless device. Data may be communicated between a wireless device and a wireless communication network over a first carrier. It may be determined whether the wireless communication network provides a fallback protocol for switching the wireless device from the first carrier to a second carrier. The wireless device may be instructed to communicate with the wireless communication network over the second carrier when it is determined that the wireless communication network does not provide the fallback protocol.

Abstract: It is identified that an attempted handover of a wireless device from a first access node to a second access node meets a failure criteria, where the attempted handover uses a handover initiation timer and a signal level modifier. A first signal level of the first access node, and a second signal level of the second access node, received at the wireless device at a time when the attempted handover was initiated are determined. At least one of the handover initiation timer and the signal level modifier is adjusted based on the failure criteria, the determined first signal level, and the determined second signal level.

Abstract: A database is maintained that maps source cell regions to channel condition on the neighbor cell(s) coverage. The database also tracks whether the neighbor cell has better, weaker, or similar signal strength than the source cell. The channel condition and bitrate requirement of each wireless device being served by the source cell are also tracked. Once a particular neighbor cell has been selected for traffic offload (i.e., handover of one or more wireless devices), the source cell uses the database to select which wireless devices should send measurement reports. Those wireless devices with channel conditions that are mapped in the database to the target cell's coverage are designated for possible selection. Among these wireless devices, either the wireless devices with the highest or lowest bitrate requirements are selected to provide measurement reports for the target cell.

Abstract: Systems and methods are described for scheduling transmissions from an access node. A location may be determined for a plurality of small cells within an access node signal area. Based on the determined locations, a scheduling algorithm may be selected for the access node, where the scheduling algorithm may comprise one of a low proportional fairness scheduling algorithm, a medium proportional fairness scheduling algorithm, and a high proportional fairness scheduling algorithm. Data may then be transmitted from the access node to a plurality of wireless devices based on the selected scheduling algorithm.

Abstract: Systems and methods are described for determining a handover condition in a wireless communication network. A plurality of active wireless devices in communication with a first access node may be detected. Measurement and reporting information may be received at the first access node from the wireless devices indicating proximity to a second access node. A criteria for selecting a wireless device in communication with the first access node for handover may be determined. A bias factor for the selected wireless device based on the received measurement and reporting information may be calculated. The bias factor may be provided to the selected wireless device and the first access node and/or a controller node may instruct the selected wireless device to communicate with the second access node.

Abstract: Systems and methods are described for implementing an inter-frequency measurement procedure in a wireless communication network. A group of wireless devices are selected based on a selection criteria. A first parameter value associated with a first access node is received from the selected group of wireless devices at the first access node. Proximity of a second access node to the first access node is estimated based on the received first parameter value. A second parameter value that is similar to the first parameter value and associated with the first access node is received from a non-selected wireless device. Quality indicators for the non-selected wireless device are monitored at the first access node. A relationship between the received first parameter value and the quality indicators for the non-selected wireless device is determined. An inter-frequency measurement procedure based on the determined relationship is initiated.

Abstract: First data packets for a wireless device are received at a network element and are encoded into at least one second data packet, the second data packet comprising at least two of the first data packets. The at least one second data packet is sent from the network element to the wireless device. A round trip time related to the at least one second data packet, and a frequency band load of a frequency band to deliver the at least one second data packet to the wireless device are determined. A number of permitted retransmissions of the at least one second data packet from the access node to the wireless device is adjusted based on the round trip time and the frequency band load.

Abstract: In systems and methods for reducing network traffic generated by a plurality of wireless devices operating over a communication network, an indication is received at an access node when a plurality of wireless devices assigned to a subscriber operate simultaneously as active wireless devices over a communication network. A priority list of the active wireless devices arranged according to the highest priority based on operating parameters of the active wireless devices is compiled. One of the active wireless devices is selected as a wireless host device based on the active wireless devices based upon the compiled priority list. Channel state data received from the active wireless devices at the access node is correlated to determine whether the active wireless devices and the wireless host device are in close proximity with each other. A wireless connection is established between the wireless host device and the active wireless devices, that are found to be in close proximity of wireless host device.

Abstract: Maps of high wireless device movement and high wireless device traffic are created. These maps are correlated over selected periods of time to determine when, and where, large numbers of wireless devices are both moving and creating problematic traffic. Stationary wireless devices using an access node in the problem area are identified before the selected time period (e.g., 30 minutes before commuting time). These stationary wireless devices are handed over to a reserved frequency band. During the selected time period, wireless devices requesting access in the problem area are denied access using the reserved frequency band and are instead forced to use another frequency band.
