Abstract: A method, system, and medium are provided for dynamically activating and deactivating power boosting operations in a mobile communications network. A determination of whether a power boosting operation is appropriate or not is made based on the network's coverage contiguity characteristics. Power boosting operations are activated when the network exhibits contiguous coverage and deactivated when the network's coverage is non-contiguous.

Abstract: When a first loading of a first access node is determined to meet a loading criteria, a handover criteria is decreased for a second access node comprising a coverage area at least a portion of which is within a coverage area of the first access node. A handover is performed of at least one of a plurality of wireless devices from the first access node to the second access node when a signal level of the second access node received at the at least one of the plurality of wireless devices meets the decreased handover criteria. Changes are determined in the first loading and in a throughput provided to the at least one of the wireless devices, and the handover criteria for the second access node is adjusted based on the changes in the first loading and the throughput provided to the at least one wireless device.

Abstract: An application requirement of an application running on a wireless device in communication with a first access node, a traffic class indicator associated with the wireless device, and a wireless communication link load between the wireless device and the first access node are determined. A probability of performing a first handover of the wireless device to a second access node and a second handover of the wireless device from the second access node to the first access node within a predetermined period of time is also determined. Based on the application requirement, the traffic class indicator, the wireless communication link load, and the determined probability, a context maintenance time is calculated, and a timer is started using the context maintenance time when the first handover is performed, and communication session information related to the communication between the wireless device and the first access node is maintained until the timer expires.

Abstract: A method and system for resolving handover in the presence of coverage area identifier conflict is disclosed. In a market area in which an LTE RAN and CDMA RAN operate, a base station receives a PCI that indicates a particular one of the LTE coverage areas detected by a mobile terminal. The base station determines that at least two of the LTE coverage areas have the particular PCI. Thereafter, the base station determines which one of the LTE coverage areas is the particular LTE coverage area that was indicated by the particular PCI based at least in part on a particular PN offset that indicates a particular CDMA coverage area of the CDMA RAN. The base station then arranges for handover to the particular LTE coverage area.

Abstract: A wireless network receives one or more data segments transmitted by a wireless communication device (WCD) in or more transmission time intervals (TTIs), estimates a size of a next data segment to be transmitted by the WCD based at least in part on sizes of the one or more data segments transmitted by the WCD, and allocates a quantity of uplink resources (e.g., a number of physical resource blocks) to the WCD for use in one or more subsequent TTIs (e.g., TTIs used for TTI bundling) based at least in part on the estimated size of the next data segment. The network may refer to an algorithm, such as a Transmission Control Protocol (TCP) congestion control algorithm, that specifies how sizes of successive data segments increase over time to predict the size of the next data segment based on the sizes of the one or more data segments.

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.

Abstract: Systems and methods are described for balancing wireless network load between band classes using automatic neighbor relations or another similar protocol. Serving cells may use neighbor lists to determine a number of first neighboring cells associated with band classes, the band classes being defined by signal frequencies. Over one or more periods of time, each of the serving cells may receive network characteristics for second neighboring cells. The neighbor lists may be reconfigured based on the network characteristics, and a number of second neighboring cells in each of the band classes in the reconfigured neighbor lists may be compared with the number of first neighboring cells in each of the band classes to determine a preferred band class for each serving cell or within a cluster of serving cells. Wireless devices may be instructed to initiate wireless connections with cells outside the preferred band class.

Abstract: Systems and methods of managing uneven data flow in a wireless communication system are provided. A network node can receive a load parameter of an access node. The network node can receive a measurement gap criteria of a wireless device in communication with the access node. The network node can receive a traffic characteristic associated with the wireless device. The network node can calculate an anticipated data burst based on the load parameter, the measurement gap criteria, and the traffic characteristic. The network node can determine an adjustment measurement gap criteria for the access node based on the anticipated data burst. The adjusted measurement gap criteria can be transmitted from the network node to the wireless device.

Abstract: A method to dynamically configure a base station based on evaluation of whether nearby and/or neighboring base stations operate on a preferred coverage frequency. For instance, the base station could be configured to broadcast as a start-scanning threshold value a relatively high value in response to determining that a base station operating on the preferred coverage frequency is located within a predefined threshold distance. Further, the base station could be configured to broadcast as the start-scanning threshold value an intermediate value in response to determining that no nearby base station operates on the preferred coverage frequency but at least one base station that is a handover neighbor operates on the preferred coverage frequency. And the base station could be configured to broadcast as the start-scanning threshold value a relatively low value in response to determining that no nearby base stations or handover neighbors operate on the preferred coverage frequency.

Abstract: A computing device may obtain n values of a first performance indicator of a network and n values of a second performance indicator of the network. The ith value of the first performance indicator may be based on a measurement of the first performance indicator within an ith time period, and the ith value of the second performance indicator may be based on a measurement of the second performance indicator within the ith time period. A set of aggregate weighted rank values of the first and second performance indicators may be determined. A jth entry in the set of aggregate weighted rank values may be selected, and the jth value of the first performance indicator and the jth value of the second performance indicator may be used to provision the network.

Abstract: Systems and methods of performing a handover in a wireless communication network are provided. A controller node can receive a first request to establish a first logical communication link between a first access node and a gateway. The controller node can receive from a second access node a second request to establish a second logical communication link between the second access node and the gateway and to release the first logical communication link between the first access node and the gateway. A timer can be initiated after receiving the second request. The timer can be based on a mobility of the wireless device, a load of the wireless communication network, and an application requirement of an application running on the wireless device. The gateway can be instructed to establish the second logical communication link after initiating the timer and to release the first logical communication link after the timer expires.

Abstract: A first throughput value is determined comprising a first total amount of data transmitted in non-final data packets from a sending network element to a wireless device and a second total amount of data in final data packets transmitted to the wireless device during a time period. A second throughput value is determined comprising the first total amount of data transmitted in non-final data packets to the wireless device during the time period less an idle time of a wireless communication link between an access node and the wireless device during the time period and less a total time to deliver the final data packets. A difference of the first throughput value and the second throughput value is calculated, and a traffic management procedure is performed when the difference of the first throughput value and the second throughput value meets a throughput threshold.

Abstract: The delivery of paging messages to an access node are delayed based on an estimated paging message load currently being handled by the access node. When a mobility node receives a request that requires a wireless device to be paged, the mobility node refers to an estimate of the current paging load on an access node. This estimate can be based on the number of paging messages that have been sent to the access node that have not elicited a response and have not expired. If the estimated load is less than a threshold amount (e.g., 80%), then the paging message can be sent to the access node without further delay. If the estimated load is greater than the threshold amount, then an amount of time to wait before sending the paging message to the access node is selected or calculated.

Abstract: Systems, methods, and computer-readable media for network handovers are provided. An eNodeB of a fourth generation mobile telecommunications network identifies available channels of a third generation mobile telecommunications network in which to handover user devices. Once an available channel is identified, the user device may be handed off to the available channel without unnecessary latency.

Abstract: A paging message is received and determined to be an alert message intended for a tracking area. Numbers of wireless devices comprising an active connection over a first channel and over a second channel in the tracking area are determined. A number of wireless devices which will respond to the alert message over the first channel and the second channel is determined based on the number of wireless devices comprising an active connection the access node on the first and second channels and a total number of connections in the tracking area. At least one wireless device comprising an active connection over the first channel is instructed to communicate over the second channel before the alert message is sent to the tracking area based on the estimated number of wireless device which will respond to the alert message over the first channel and the second channel.

Abstract: In operation, a plurality of data packets is received from a wireless device in communication with a first network, the data packets comprising an indication of first network congestion. The plurality of data packets are examined to determine an application requirement and a data rate of an application running on the wireless device. When a number of indications of first network congestion in relation to the data rate meets a congestion criteria, which can be based on the application requirement, a handover is performed to hand over the wireless device to a second network.

Abstract: In systems and methods of managing tracking area updates, tracking area update messages received from a wireless device are monitored, where the tracking area update messages are received from a wireless device when the wireless device changes between communicating over a first channel associated with a first tracking area identifier and a second channel associated with a second tracking area identifier. The first tracking area identifier comprises a unique tracking area code and a first network identifier, and the second tracking area identifier comprises the unique tracking area code and a second network identifier. When a number of the tracking area update messages received from the wireless device meets a message threshold, the wireless device is instructed to not send a next tracking area update message.

Abstract: In systems and methods of tracking area configuration, a number of tracking area update messages received by a plurality of access nodes using a first tracking area configuration are monitored. It is determined that a number of tracking area update messages received by one of the plurality of access nodes meets an update message criteria. It is also determined that a number of connected wireless devices at the one of the plurality of access nodes meets a connection criteria. When the number of tracking area update messages meets the update message criteria and when the number of connected wireless devices meets the connection criteria, the second tracking area configuration is used at the access node.
