The present invention is further detailed explanation with detailed description of the invention.
In the embodiment of the present invention, the first presetting rule be PDU abandon condition, as PDU receive window
Outward, and for example PDU attach most importance to multiple connection receive PDU etc..Then abandon condition then think this PDU when PDU meets
Meet the first presetting rule, and when POLL position=1 of this PDU, generation state report can be triggered
Accuse.
Second presetting rule is another rule that PDU can trigger the report of generation state, and concrete is permissible
By state variable the SN of PDU weighed and judge again.Wherein, state variable includes: maximum shape
State sends state variable VR (MS) and highest received state VR (MR).Then as SN < VR (MS)
Or during SN >=VR (MR), the SN of PDU meets the second presetting rule, and as the POLL of this PDU
During position=1, the report of generation state can be triggered.
Wherein, state variable can be updated after receiving PDU every time.
Background technology is in data receiver processes, as the PDU (SN=X of this PDU) receiving POLL=1
SN when being unsatisfactory for the second presetting rule, need the triggering that delay state is reported.When implementing,
Need to preserve SN i.e. X, after receiving new PDU afterwards and making state variable update, then sentence
Whether the SN of disconnected above-mentioned record meets the second presetting rule, thus decides whether to the report of triggering state.
But, during the actual data receiver at rlc layer processes, it is most likely that occur " having been received by
The PDU of SN=X1 needs Time-delayed trigger state to report, have received the most again multiple POLL=1 PDU (as
SN=X2, X3, X4 etc.) and all it is unsatisfactory for the second presetting rule, the condition of state report need to be triggered "
On the one hand situation, now need that these SN (X1, X2, X3 and X4 etc.) are all carried out record and protect
Deposit, on the other hand, the most often receive a new PDU, be required for after the SN preserved and renewal
State variable compares, to decide whether to the report of triggering state.The value of the SN preserved is the most, just
More affect the efficiency of data receiver process, cause that data receiver processes is inefficient.
The embodiment of the present invention provides the method for receiving and processing data of a kind of rlc layer, is unsatisfactory for pre-at PDU
When putting triggering rule, according to the SN of PDU, the state report of Time-delayed trigger is operated, including: touch
