Method and apparatus for handling timers during reestablishing transmitting sides in wireless communications systems
View Patent ↗A communications device utilized in a wireless communications system has an RLC entity with a transmitting side and a receiving side. Handling timers during reestablishment of the transmitting side includes only reestablishing the transmitting side in the RLC entity of the communications device, stopping a first timer corresponding to the transmitting side, and prolonging and not stopping a second timer corresponding to the transmitting side. The second timer is not a periodic timer.
1. A method of handling timers during re-establishing a transmitting side of a wireless communications system having a communications device having an RLC (Radio Link Control) entity having a transmitting side and a receiving side, wherein when both the transmitting side and the receiving side in the RLC entity are being re-established, a first timer corresponding to the transmitting side is stopped and a second timer corresponding to the receiving side is stopped, the method comprising:
re-establishing the transmitting side in the RLC entity and not re-establishing the receiving side in the RLC entity;
stopping the first timer;
not stopping the second timer when re-establishing the transmitting side in the RLC entity and not re-establishing the receiving side in the RLC entity;
wherein the second timer is not a periodic timer; and
wherein stopping the first timer corresponding to the transmitting side is stopping all timers corresponding to the transmitting side other than an SDU discard timer (Timer_Discard) and a periodic polling timer (Timer_Poll_Periodic).
2. A communications device utilized in a wireless communications system, an RLC (Radio Link Control) entity of the communications device having a transmitting side and a receiving side, utilized for accurately establishing the transmitting side, wherein when both the transmitting side and the receiving side in the RLC entity are being re-established, a first timer corresponding to the transmitting side is stopped and a second timer corresponding to the receiving side is stopped, the communications device comprising:
a control circuit for realizing functions of the communications device;
a central processing unit for executing a program code to operate the control circuit; and
a memory for storing the program code;
wherein the processor executes the program code to:
re-establish the transmitting side in the RLC entity and not re-establishing the receiving side in the RLC entity;
stop the first timer;
not stop the second timer when re-establishing the transmitting side in the RLC entity and not re-establishing the receiving side in the RLC;
wherein the second timer is not a periodic timer; and
wherein stopping the first timer corresponding to the transmitting side is stopping all timers corresponding to the transmitting side other than an SDU discard timer (Timer_Discard) and a periodic polling timer (Timer_Poll_Periodic).
3. The method of claim 1 , wherein the periodic timer is a periodic status timer (Timer_Status_Periodic).
4. The method of claim 1 , wherein the second timer corresponding to the receiving side is a status prohibiting timer (Timer_Status_Prohibit).
5. The method of claim 1 , wherein the wireless communications system operates in acknowledged mode (AM).
6. The method of claim 1 , wherein the communications device is a mobile phone, a wireless mobile phone, a wireless communications device, or a networking device.
7. The device of claim 2 , wherein the wireless communications system operates in acknowledged mode (AM).
8. The device of claim 2 , wherein the communications device is a mobile phone, a wireless mobile communications device, or a networking device.
9. The device of claim 2 , wherein the periodic timer is a periodic status timer (Timer_Status_Periodic).
10. The device of claim 2 , wherein the second timer corresponding to the receiving side is a status prohibiting timer (Timer_Status_Prohibit).
