Method and related apparatus for handling re-establishment of radio link control entity in a wireless communications system
View Patent ↗A method for handling re-establishment of a radio link control entity having a transmitting side and a receiving side in a wireless communications system includes storing a plurality of control protocol data units, and reserving a poll super field in the plurality of control protocol data units when only the receiving side is re-established.
1. A method for handling re-establishment of a radio link control entity having a transmitting side and a receiving side in a wireless communications system comprising:
storing a plurality of control protocol data units including a status protocol data unit corresponding to the transmitting side and the status protocol data unit containing a poll super field; and
reserving the poll super field in the plurality of control protocol data units when only the receiving side is re-established.
2. The method of claim 1 further comprising reserving a move receiving window super field in the plurality of control protocol data units.
3. The method of claim 1 further comprising discarding an acknowledgement status report, a window size super field, a move receiving window acknowledgement super field, a reset protocol data unit, and a reset acknowledgement protocol data unit in the plurality of control protocol data units.
4. A communications device for handling re-establishment of a radio link control entity having a transmitting side and a receiving side in a wireless communications system comprising:
a control circuit for realizing functions of the communications device;
a processor installed in the control circuit, for executing a program code to command the control circuit; and
a memory installed in the control circuit and coupled to the processor for storing the program code;
wherein the program code comprises:
storing a plurality of control protocol data units including a status protocol data unit corresponding to the transmitting side and the status protocol data unit containing a poll super field; and
reserving the poll super field in the plurality of control protocol data units when only the receiving side is re-established.
5. The communications device of claim 4 , wherein the program code further comprises reserving a move receiving window super field in the plurality of control protocol data units.
6. A communications device of claim 4 , wherein the program code further comprises discarding an acknowledgement status report, a window size super field, a move receiving window acknowledgement super field, a reset protocol data unit, and a reset acknowledgement protocol data unit in the plurality of control protocol data units.
7. A method for handling re-establishment of a radio link control entity having a transmitting side and a receiving side in a wireless communications system comprising:
storing a plurality of control protocol data units including a status protocol data unit corresponding to the transmitting side and the status protocol data unit containing a poll super field; and
discarding the poll super field in the plurality of control protocol data units when only the transmitting side is re-established.
8. The method of claim 7 further comprising discarding a move receiving window super field, a reset protocol data unit, and a reset acknowledgement protocol data unit in the plurality of control protocol data units.
9. The method of claim 7 further comprising reserving an acknowledgement status report, a window size super field, and a move receiving window acknowledgement super field in the plurality of control protocol data units.
10. A communications device for handling re-establishment of a radio link control entity having a transmitting side and a receiving side in a wireless communications system comprising:
a control circuit for realizing functions of the communications device;
a processor installed in the control circuit, for executing a program code to command the control circuit; and
a memory installed in the control circuit and coupled to the processor for storing the program code;
wherein the program code comprises:
storing a plurality of control protocol data units including a status protocol data unit corresponding to the transmitting side and the status protocol data unit containing a poll super field; and
discarding the poll super field in the plurality of control protocol data units when only the transmitting side is re-established.
11. The communications device of claim 10 , wherein the program code further comprises discarding a move receiving window super field, a reset protocol data unit, and a reset acknowledgement protocol data unit in the plurality of control protocol data units.
12. The communications device of claim 10 , wherein the program code further comprises reserving an acknowledgement status report, a window size super field, and a move receiving window acknowledgement super field in the plurality of control protocol data units.
