摘要： Certain aspects of the present disclosure relate to techniques for improving a circuit-switched fallback (CSFB) user experience. In aspects, methods and systems for autonomously returning a user equipment (UE) from a 2G (2nd generation)/3G (3rd generation) network to an LTE (Long Term Evolution) network are provided. The UE may store a flag to note whether a current circuit switched (CS) call in the 2G/3G network is a result of a CSFB. The UE, in response to detecting a termination of the current CS call in the 2G/3G network and determining that the terminated call was a CSFB call (e.g., from the status of the flag), may trigger a mobility mechanism to autonomously return the UE to the LTE network.

摘要： When a user equipment performs inter-cell measurement, it may desire to measure signal quality and signal level of a source radio access technology (RAT) cell and a target cell. The signal quality measurement may be Squal and the signal level measurement may be Srxlev. Because Squal is not defined for TD-SCDMA, a new measurement criteria is defined to allow proper comparison of source RAT cell measurements with target RAT cell measurements when a user equipment is considering switching to a target cell.

摘要： Apparatus and methods are described herein for efficiently handing over a user equipment from an earlier-technology network back to a later-technology network upon detecting the end of a coverage hole in the later-technology network. The UE may be configured to measure signals from the later-technology network. When the UE discovers, upon establishment or reestablishment of a PS data connection, that the later-technology network signal exceeds a defined threshold, the UE may initiate a handover back to the later-technology network.
