摘要： Embodiments of the present disclosure are directed toward devices and methods for fast radio link recovery in cellular networks. In one embodiment, the signal strength of the serving cell is compared to the signal strength of a target cell, and a radio link failure (RLF) timer is terminated or shortened based on the comparison. Alternatively, a second shorter timer may be used as opposed to modifying the current timer. In some embodiments, the modification of RLF timers may be triggered by the start of a measurement trigger timer. This may allow a user equipment to more quickly establish a connection with a target cell in situations where radio link failure or handover failure are likely to occur. In some instances, the parameters for terminating or shortening the radio link failure timer, or starting an additional timer, may be provided to the user equipment by a network.
