INTER-RAT (RADIO ACCESS TECHNOLOGY) AND INTRA-RAT MEASUREMENT REPORTING

摘要

A measurement report may trigger a handover based on relative signal strengths of a serving cell and an intra/inter-RAT (radio access technology) neighbor cell. This may result in a UE being handed over to a weak cell and cause a voice call to drop. A method of wireless communication includes determining whether to delay sending an inter-RAT or an intra-RAT measurement report based in part on a current status of a call setup and whether the UE and a network support an inter-RAT handover while in the current status of the call setup. The measurement report is delayed for a predetermined time period based in part on the determination. The method also includes sending the measurement report when the predetermined time period expire and/or the current status of the call setup changes to a new status when both the UE and the network support the inter-RAT handover.

1. A method of wireless communication at a user equipment (UE) during a call setup, comprising:
determining whether to delay sending an inter-RAT (radio access technology) measurement report or an intra-RAT measurement report based at least in part on a current status of the call setup and whether both the UE and a network support an inter-RAT handover while in the current status of the call setup, a network being a serving network or a target network; delaying sending the intra-RAT measurement report for an intra-RAT measurement report holding time period and/or an inter-RAT measurement report for an inter-RAT measurement report holding time period based at least in part on the determination; and sending the intra-RAT measurement report and/or the inter-RAT measurement report when the intra-RAT measurement report holding time period and/or the inter-RAT measurement report holding time period expire and/or the current status of the call setup changes to the new current status of the call setup in which both the UE and the network support the inter-RAT handover.
