    • 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.
    • 本公开的实施例涉及用于蜂窝网络中的快速无线电链路恢复的设备和方法。 在一个实施例中,将服务小区的信号强度与目标小区的信号强度进行比较,并且基于比较终止或缩短无线电链路故障(RLF)定时器。 或者,可以使用第二较短的定时器,而不是修改当前定时器。 在一些实施例中,RLF定时器的修改可以由测量触发定时器的启动触发。 这可能允许用户设备在可能发生无线电链路故障或切换故障的情况下更快地建立与目标小区的连接。 在一些情况下,用于终止或缩短无线电链路故障定时器或启动附加定时器的参数可以由网络提供给用户设备。
