Abstract

Devices and methods for intelligent handover requests and management are disclosed. IRAT handover failure can be prevented by ensuring that user equipment (UE) is asked to handover to a target cell that it has already measured, and that resource allocation in the base station sub-system (BSS) is made in the correct cell. For instance, a radio network controller (RNC) can maintain cell identification and corresponding node information when an updated measurement control message is sent to the UE. According to certain aspects, a relocation cancellation message can be sent from an RNC to a mobile switching center (MSC) if a new measurement report, such as a 3a report, is received by the RNC.
