Abstract: A communications system may include a user equipment (UE) device that communicates with a cellular network having base stations. A UE may enter a connected mode in which the UE and a first base station in a first cell convey wireless data. While in connected mode, the first base station may transmit measurement objects to the UE, each being associated with a different cell neighboring the first cell. The UE may store the measurement objects. When the UE enters an idle mode, the UE may perform measurements on the neighboring cells using the measurement objects. The UE may then use the measurements to determine whether to re-select to a neighbor cell when the UE is unable to acquire a measurement configuration from the base station in idle mode. This may help to mitigate the occurrence of idle mode out-of-service (OOS) conditions for the UE device.

Abstract: Methods, apparatuses, and systems are disclosed for reducing latency during IRAT re-selection in the presence of race conditions. When a UE initiates an IRAT re-selection procedure, and concurrently initiates a call setup procedure, a race condition may result, in which the UE's NAS layer prioritizes the call setup procedure, while the RRC layer prioritizes the IRAT re-selection procedure. This may result in failure of the call setup procedure, which may lead to a user needing to re-initiate the call, resulting in poor user experience and significant latency. To prevent this, the UE may cache a message and/or other information relevant to the call setup procedure, until the IRAT re-selection procedure is complete. The UE may then proceed to complete the call setup procedure. The message may be cached, e.g., at the NAS layer or the RRC layer of the cellular modem, or by an application processor.
