Abstract:
In some embodiments, a user equipment device (UE) implements techniques for avoiding conflicts between UE-initiated and network-initiated handovers. In one embodiment, one or more first radios are configured to perform cellular communication using different first and second cellular radio access technologies (RATs) and a second radio is configured to perform wireless communication using a short-range RAT. In one embodiment, the mobile device is configured to, while communicating using the first cellular RAT, in response to determining that an inter-RAT handover to the short-range RAT is likely to be initiated or has been initiated by the at least one processor, delay sending a measurement report to the cellular base station. This delay may avoid conflict between handovers initiated by the network in response to the measurement report (e.g., from the first cellular RAT to the second cellular RAT) and the inter-RAT handover.
