Claim Text:
1. A method of enhanced radio resource control (RRC) reestablishment in a communication system, comprising: incrementing a counter value associated with a first cell based on a detection of a radio link failure (RLF) by a user equipment (UE) in a RRC connected state with the first cell; determining that the counter value meets or exceeds a first barring threshold value within a cell barring evaluation time duration; prohibiting the UE from performing an RRC reestablishment procedure with the first cell for a first barring time duration in response to a determination that the counter value meets or exceeds the first barring threshold value within the cell barring evaluation time duration; detecting a first RLF and a second RLF for the first cell that occur after expiration of the first barring time duration, wherein the first RLF is detected at a first time value and the second RLF is detected at a second time value; determining that a time duration between the first time value and second time value meets or exceeds a reset time duration; and performing an RRC reestablishment with the first cell in response to a determination that the time duration between the first time value and second time value meets or exceeds the reset time duration.
