Abstract: Systems and methods are provided for determining precedence between Radio Access Network (RAN) rules and Access Network Discovery and Selection Function (ANDSF) rules when a mobile communication device has access to more than one set of rules for offloading data. Systems and methods for transmitting an offloadable Access Point Name (APN) to a mobile communication device when RAN rules are used. Embodiments of the present disclosure combine the advantages of signaling methods when offloading information to a mobile communication device after a RAN rule has been satisfied such that a base station is able to broadcast a signal that enables all devices camped on an serving cell to offload to the APN.

Abstract: A wireless communication device communicating with a serving base station in a wireless communication environment may have one or more applications running. When seeking to handover from the serving base station to a target base station, the wireless communication device adjusts the configurations of the applications based on the new communication link properties. Likewise, when an application is loaded that prefers communication link properties that exceeds a current communication link's capabilities, the wireless communication device may seek out and hand over to other communication links. By cooperatively coordinating the functionality of installed applications with communication link properties, the wireless communication device can maintain high levels of device and application functionality.

Abstract: In a Long Term Evolution (LTE) environment, the LTE network can coordinate with a subscribing user equipment to manage offloading to a wireless local area network (WLAN) access point or other base station. In doing so, the serving base station on the LTE network can acquire device capabilities of the user equipment and provide configuration details to the user equipment based on those capabilities. These configuration details may cause the user equipment to monitor one or more triggers, and may configure a scan to be later performed by the user equipment. Based on the monitored trigger, the user equipment can then scan the environment according to the scan configuration defined by the base station, and relay scan results to the base station to make a handover determination.

Abstract: Carrier aggregation and dual connectivity allow a user device to communicate with one or more base stations on multiple component carrier frequencies. When it is determined that the user device should handover to a new base station, the user device performs a substantial portion of the needed handover operations with the new base station using only one of the component carrier frequencies. Meanwhile, the user device maintains data communications with the original base station on the remaining component carrier frequencies.

Abstract: Methodologies and apparatus to support interworking operations between a cellular radio area network (RAN) and a wireless local area network (WLAN) utilizing broadcast RAN assistance information. In various embodiments, a RAN (such as a LTE/LTE-advanced RAN) transmits RAN assistance information to a multimode user equipment (UE) for use in network selection and traffic steering operations. Certain parameters, such as RAN load assistance information, may be transmitted in a first format or a second, less granular format that changes relatively infrequently over time as compared to the first format. A system information broadcast procedure utilizing a paging message is employed to transmit information in the second format. The paging message may include a change notification flag that triggers a UE to initiate a system information acquisition procedure to a retrieve system information message(s) including the relevant interworking parameters.

Abstract: Systems and methods for adaptive access and handover configuration based on historical data are provided. Access and handover decisions are optimized in a multiple radio access technology environment using historical data associated with network performance. Future needs for access and handovers are predicted using historical data associated with the user and historical data associated with network performance. Performance metrics are received periodically or continuously from nodes in one or more networks at a centralized controller. The centralized multi RAT controller correlates these performance metrics and determines predicted handovers for a user device. Preparations for the predicted handovers can then be made prior to the handover event.
