Maintaining communication between mobile terminal and network in mobile communication system
First Claim
1. A method for maintaining a communication between a mobile terminal and a network in a mobile communication system, the method comprising:
- determining whether a state of the mobile terminal is in an unsynchronized state while maintaining a radio resource control (RRC) connected state with the network;
performing a random access channel (RACH) procedure for a synchronized state if it is determined that the state of the mobile terminal is in the unsynchronized state while maintaining the RRC connected state with the network; and
after performing the RACH procedure, transitioning from the synchronized state to the unsynchronized state with the network while maintaining the RRC connected state with the network when a timer expires.

Abstract
According to one embodiment, a method for maintaining a communication between a mobile terminal and a network in a mobile communication system includes: determining whether a state of the mobile terminal is in an unsynchronized state while maintaining a radio resource control (RRC) connected state with the network; performing a random access channel (RACH) procedure for a synchronized state if it is determined that the state of the mobile terminal is in the unsynchronized state while maintaining the RRC connected state with the network; and after performing the RACH procedure, transitioning from the synchronized state to the unsynchronized state with the network while maintaining the RRC connected state with the network when a timer expires.

10. A mobile terminal for maintaining communication with a network in a mobile communication system, the mobile terminal comprising:
-
a processor configured to; determine whether a state of the mobile terminal is in an unsynchronized state while maintaining a radio resource control (RRC) connected state with the network; perform a random access channel (RACH) procedure for a synchronized state if it is determined that the state of the mobile terminal is in the unsynchronized state while maintaining the RRC connected state with the network; and after performing the RACH procedure, transition the state of the mobile terminal from the synchronized state to the unsynchronized state with the network while maintaining the RRC connected state with the network when a timer expires. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
