PROBLEM TO BE SOLVED: To provide a method and apparatus for controlling a plurality of timers associated with the ISR function.SOLUTION: The method is applicable to UE moving between mutually 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 (P-TAU) timer. The method comprises starting the deactivate ISR timer when the P-TAU timer expires and a mobility management back-off (MM-BO) timer is running while the UE is in the coverage of LTE.SELECTED DRAWING: Figure 6 |
