The technical features of this document provide a method and wireless apparatus for controlling a number of timers associated with ISR function. The method is applicable to a user equipment moving between different networks, i.e., different radio access networks such as 2G/3G and LTE. The method is associated with a deactivate timer which can be initiated following a periodic tracking area updating timer. The method comprises starting the deactivate ISR timer when the periodic tracking area updating timer expires and the mobility management back-off timer is running while the UE is in the coverage of LTE. |
