Method of managing E-UTRA function of user equipment and related wireless communication system

摘要

In a wireless communication system, when a user equipment needs to deactivate its E-UTRA function due to a network related failure cause, a waiting period is set according to the mobility information of the user equipment. When the waiting period has elapsed after deactivating the E-UTRA function, the user equipment is configured to reactivate the E-UTRA function.

1. A method of managing an evolved universal terrestrial radio access (E-UTRA) function of a user equipment (UE), comprising:
the user equipment activating the E-UTRA function; acquiring mobility information of the user equipment by measuring at least one of a UE mobility state, a UE velocity and a change in the UE mobility state during a specific period; setting a waiting period according to the mobility information when determining that the E-UTRA function needs to be deactivated; the user equipment deactivating the E-UTRA function; and the user equipment reactivating the E-UTRA function when the waiting period has elapsed after deactivating the E-UTRA function, wherein:
the waiting period is set to a first value when the mobility information corresponds to a high UE mobility state, a fast UE velocity or a large change in the UE mobility state;the waiting period is set to a second value when the mobility information does not correspond to any of the high UE mobility state, the fast UE velocity and the large change in the UE mobility state; andthe first value is smaller than the second value.
