Method and apparatus for handling timers during re-establishing receiving sides in a wireless communications system
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 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.
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.
