Abstract: Methods, systems, and devices are described for improving inter-network mobility performance in multiple network wireless communication systems by using channel avoidance information from a first network using a first radio access technology (RAT) to modify inter-RAT behavior of a second network using a second RAT. In some embodiments, the second network queries the first network for channel avoidance information and applies the channel avoidance information in suppressing inter-RAT channel measurements, avoiding inter-RAT redirection, and/or avoiding inter-RAT reselection. In embodiments, inter-RAT channel measurement suppression, inter-RAT redirection avoidance, and/or inter-RAT reselection avoidance is performed by the mobile device. In other embodiments, channel avoidance information of the first network may be communicated to other network entities of the second network and one or more of these entities may modify various inter-RAT behaviors.

Abstract: Systems and methodologies are described herein that facilitate efficient transfer of quality of service (QoS) context during inter-radio access technology (RAT) handovers. In particular, techniques are described herein for establishing rules for whether a user equipment unit (UE) or an associated network should establish QoS for a mixed-mode application, identifying flow to bearer mappings when translating QoS across an inter-RAT handover, mapping QoS parameters of respective RATs, mitigating QoS depreciation upon multiple handovers, performing one or more actions if QoS is not acceptable in a new RAT, maintaining QoS during tunnel mode, and handling scenarios in which a UE moves between a RAT using network-initiated QoS and a RAT using UE-initiated QoS.

Abstract: Aspects of the present disclosure are directed to methods and apparatus for selective better system reselection for wireless devices capable of cell reselection. An apparatus for wireless communication is configured to receive a message from a current system, the message including a neighbor list having one or more neighbor systems. The apparatus compares the neighbor list to a local preferred systems list, and determine an existence of a preferred neighbor system in the local preferred systems list. The preferred neighbor system has higher priority than that of the neighbor systems in the neighbor list. The apparatus determines whether to perform Better System Reselect (BSR) for the preferred neighbor system instead of cell reselection based on the determination.
