Abstract
An user equipment and a data connection recovery method thereof are provided. The user equipment transmits at least one UDP query packets to a robust server via the base station, and determines that there is no response from the robust server during a default period. Then the user equipment determines that a data connection with a backhaul network is abnormal between the base station and the backhaul network. Accordingly, the user equipment transmits a trigger packet to the backhaul network via the base station under NAS protocol and recovers the data connection with the backhaul network.
