Abstract

A communications device utilized in a wireless communications system has an RLC entity with a transmitting side and a receiving side. Handling timers during re-establishment of the receiving side includes only re-establishing the receiving side in the RLC entity of the communications device, stopping a first timer corresponding to the receiving side, and prolonging and not stopping a second timer corresponding to the transmitting side.

Claims (23)

1. A method of handling timers during re-establishing a receiving side of a wireless communications system having a communications device having an Radio Link Controller (RLC) entity having a transmitting side and a receiving side, the method comprising, in step of:

only re-establishing the receiving side in the Radio Link Controller (RLC) entity of the communications device;

stopping a first timer corresponding to the receiving side; and

keeping on counting and not stopping a second timer corresponding to the transmitting side to allow the missing poll to be retransmitted;

wherein the second timer corresponding to the transmitting side is a polling timer (Timer_Poll).

2. A communications device utilized in a wireless communications system, an Radio Link Controller (RLC) entity of the communications device having a transmitting side and a

receiving side, utilized for accurately reestablishing the receiving side, the wireless communications device comprising:

a control circuit for realizing functions of the wireless 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 program code comprises, in step of:

only re-establishing the receiving side in the Radio Link Controller (RLC) entity;

stopping a first timer corresponding to the receiving side; and

keeping on counting and not stopping a second timer corresponding to the transmitting side to allow the missing poll to be retransmitted;

wherein the second timer corresponding to the transmitting side is a polling timer (Timer_Poll).

3. The communications device of claim 2 , wherein stopping the first timer corresponding to the receiving side is stopping all timers corresponding to the receiving side except a periodic status report timer (Timer_Status_Periodic).

4. The communications device of claim 2 , wherein the first timer corresponding to the receiving side is a status report prohibition timer (Timer_Status_Prohibit).

5. The communications device of claim 2 , wherein the wireless communications system operates in Acknowledge Mode.

6. The communications device of claim 2 , wherein the communications device is a mobile phone, a wireless mobile communications device, or a networking device.

7. The method of claim 1 , wherein stopping the first timer corresponding to the receiving side is stopping all timers corresponding to the 20 receiving side except a periodic status report timer (Timer_Status_Periodic).

8. The method of claim 1 , wherein the first timer corresponding to the receiving side is a status report prohibition timer (Timer_Status_Prohibit).

9. The method of claim 1 , wherein the wireless communications system operates in Acknowledge Mode.

10. The method of claim 1 , wherein the communications device is a mobile phone, a wireless mobile communications device or a networking device.
