Abstract

A method for handling timers in a wireless communication system includes starting a Timer_Poll_Periodic timer for a Radio Link Control Acknowledged Mode (RLC AM) entity, performing a re-establishment procedure for the RLC AM entity, and not stopping the Timer_Poll_Periodic timer after re-establishment of the RLC AM entity.

Claims

1. A method for handling timers in a wireless communications system, the method comprising:

starting a Timer_Poll_Periodic timer for a Radio Link Control Acknowledged Mode (RLC AM) entity;

performing a re-establishment procedure for the RLC AM entity; and

not stopping the Timer_Poll_Periodic timer after re-establishment of the RLC AM entity.

2. The method of claim 1 further comprising maintaining a value of the Timer_Poll_Periodic timer and maintaining operation of the Timer_Poll_Periodic timer after re-establishment of the RLC AM entity.

3. The method of claim 1 further comprising restarting the Timer_Poll_Periodic timer after re-establishment of the RLC AM entity.
