Abstract
A reset method for an AM RLC entity, the method comprising: receiving a reset PDU that includes a RSN; and if the received reset PDU is not the first received reset PDU after re-establishment of the RLC entity and if the RSN is the same as a RSN included in a last received reset PDU, re-transmitting the reset ACK PDU that was last transmitted. The method further comprising: if the received reset PDU is the first received reset PDU after re-establishment of the RLC entity or if the RSN is not the same as a RSN included in a last received reset PDU, transmitting a reset ACK PDU.
Claims16
A reset method for a receiving side Acknowledged Mode Radio Link Control entity, the method comprising:
- receiving, from a transmitting side, a reset Protocol Data Unit that includes a Reset Sequence Number;
- and
- if the received reset Protocol Data Unit is not the first received reset Protocol Data Unit after re-establishment of the Radio Link Control entity and if the Reset Sequence Number is the same as a Reset Sequence Number included in a last received reset Protocol Data Unit, re-transmitting a reset Acknowledgement Protocol Data Unit that was last transmitted to the transmitting side.
A reset method for a transmitting side Acknowledged Mode Radio Link Control entity, the method comprising:
- transmitting, to a receiving side, a reset Protocol Data Unit that includes a Reset Sequence Number;
- and
- receiving, from the receiving side, a re-transmission of a reset Acknowledgement Protocol Data Unit that was last transmitted, if the receiving side determined that the received reset Protocol Data Unit is not the first received reset Protocol Data Unit after re-establishment of the Radio Link Control entity and determined that the Reset Sequence Number is the same as a Reset Sequence Number included in a last received reset Protocol Data Unit.
A reset method for a receiving side protocol entity, the method comprising:
- receiving, from a transmitting side protocol entity, a reset request that includes a reset indicator;
- determining whether the received reset request is not the first received reset request after re-establishment of the protocol entity;
- determining whether the reset indicator is the same as a reset indicator included in a last received reset request;
- and
- re-transmitting, to the transmitting side protocol entity, a reset response that was last transmitted, if both conditions of the above two determining steps are satisfied.
A reset method for a transmitting side protocol entity, the method comprising:
- transmitting, to a receiving side protocol entity, a reset request that includes a reset indicator;
- and
- receiving, from the receiving side protocol entity, a re-transmission of a reset response that was last transmitted, if the receiving side protocol entity determined that the received reset request is not the first received reset request after re-establishment of the protocol entity, and determined that the reset indicator is the same as a reset indicator included in a last received reset request.
