1. At least one non-transitory computer readable storage medium having stored thereon instructions that, when executed by a computing device, cause the computing device to perform a method, the method comprising:

  • receiving configuration information from a base station in a one-to-one message;

    configuring a set of radio link failure timers based on a set of speeds of the mobile user device indicated by the configuration information,wherein a radio link failure timer is set for longer when the mobile user device is moving at a high speed than it is when the mobile user device is moving at a low speed;

    detecting a radio link quality below a predetermined threshold;

    starting the set of radio link failure timers in response to detecting the radio link quality below the predetermined threshold;

    after starting the set of radio link failure timers, determining a speed of the mobile user device;

    selecting a timer from the set of radio link failure timers based on the current speed of the mobile user device; and

    declaring a radio link failure when the radio link failure timer expires.
