Patent Images
1. A method of reconfiguring a timer of a mobile terminal in wireless communication system, the method comprising:
- receiving a first timer value from a network;
configuring, at a media access control (MAC) layer of the mobile station, a timer with the first timer value;
starting, at the MAC layer of the mobile station, the timer based on the first timer value by receiving a command;
receiving a second timer value from the network before the timer is expired;
configuring, at the MAC layer of the mobile station, the timer with the second timer value; and
restarting, at the MAC layer of the mobile station, the timer based on the second timer value without receiving another command,wherein the first timer value, the second timer value, and the command are received by an MAC protocol data unit (PDU),wherein the MAC PDU includes a MAC header, a MAC service data unit (SDU), and a MAC control element (CE), andwherein the MAC CE includes the first timer value, the second timer value, and the command.

7. A method of reconfiguring a timer of a mobile terminal in wireless communication system, the method comprising:
-
receiving a first timer value from a network; configuring, at a media access control (MAC) layer of the mobile station, a timer with the first timer value; starting, at the MAC layer of the mobile station, the timer based on the first timer value by receiving a first command; receiving a second timer value from the network before the timer is expired; storing the second timer value temporarily; receiving a second command for restarting the timer from the network; configuring, at the MAC layer of the mobile station, the timer with the second timer value; and restarting, at the MAC layer of the mobile station, based on the second timer value if there the second timer value exists when the second command is received, wherein the first timer value, the second timer value, the first command, and the second command are received by an MAC protocol data unit (PDU), wherein the MAC PDU includes a MAC header, a MAC service data unit (SDU), and a MAC control element (CE), and wherein the MAC CE includes the first timer value, the second timer value, the first command, and the second command. - View Dependent Claims (8, 9, 10, 11, 12)
