Description
Technical field
(Long Term Evolution, LTE) technology relate in particular to a kind of based on Radio Link control (Radio Link Control, RLC) processing method and the system of confirmation in the protocol validation pattern to the present invention relates to the 3G (Third Generation) Moblie Long Term Evolution.
Background technology
The RLC of LTE system generally comprises three types RLC entity: transparent mode (TM) RLC entity, Unacknowledged Mode (UM) RLC entity and affirmation mode (AM) RLC entity, wherein, the AMRLC entity generally comprises AM RLC entity and sends part and AM RLC entity receiving unit, in data transmission procedure, the receiving unit of transmitting end AM RLC entity mainly receives from the upper strata, it is the radio link control service data unit (RLC SDU) of PDCP (PDCP) layer, the RLC SDU that is received is handled, after being converted into one or more acknowledged mode data protocol Data Units (AMD PDU), sending part by it again and pass through low layer, be that medium access control (MAC) layer sends AMD PDU after the conversion to receiving terminal AM RLC entity; The receiving unit of receiving terminal AM RLC entity mainly by low layer, be that the MAC layer receives the AMDPDU that sends from transmitting end AM RLC entity, be converted into RLC SDU after, send part by it again and be delivered to the upper strata, be the PDCP layer.
Generally speaking, transmitting end AM RLC entity safeguards that by confirming state variable (Acknowledgementstate variable) VT (A) and maximum send state variable (Maximum send state variable) VT (MS) sends a window (transmitting window), wherein, VT (A) is the lower boundary that sends window, its value is represented to send among the AMD PDU that is not identified, sequence number (Sequence Number, SN) SN of Zui Xiao AMD PDU, promptly SN is successfully confirmed in the transmission of VT (A) AMD PDU before; VT (MS) is the coboundary that sends window, and its value is VT (A)+transmission window length.In addition, transmitting end AM RLC entity can safeguard that also a send state variable (Send state variable) VT (S) is used for transmit operation, and its value is for distributing to the next SN that needs the AMD PDU of transmission.
Transmitting end AM RLC entity only sends SN and is positioned at the AMD PDU that sends window, if promptly the SN of AMDPDU is t, under the situation of VT (A)＜=t＜VT (MS) of then satisfying condition, send described AMD PDU, when new AMD PDU need send to low layer, it is VT (S) that the SN that described new needs send to the AMDPDU of low layer is set, and VT (S) value adds one, to indicate next assignable SN.
Receiving terminal AM RLC entity can return affirmation information about reception AMD PDU to transmitting end AM RLC entity, so that transmitting end AM RLC entity carries out respective handling according to confirmation, thereby the normal operation of carrying out in order of guarantee sending and system, the affirmation information that receiving terminal AM RLC entity returns to transmitting end AM RLC entity can be the affirmation information about an AMD PDU, also can be a plurality of AMD PDU, be that receiving terminal AM RLC entity can return confirmation at the AMD PDU of a transmission success, also can return confirmation at the AMD PDU of a plurality of transmission success.Fig. 1 is in the prior art, and transmitting end AM RLC entity is received the process flow figure after the confirmation, and as shown in Figure 1, in the prior art, transmitting end AM RLC entity is received and comprised step after the confirmation:
Step 11: transmitting end AM RLC entity receives the affirmation information from receiving terminal AM RLC entity.
Can carry the SN of the AMD PDU of transmission success in the confirmation.
Step 12: judge the affirmation that whether comprises in the described confirmation the corresponding A MDPDU of lower boundary institute that sends window, if, execution in step 13; Otherwise, forward step 14 to.
If carry in the confirmation among the SN of AMD PDU, exist and the identical SN of lower boundary that sends window, then comprise affirmation in the confirmation to the corresponding A MD PDU of lower boundary institute that sends window, otherwise, then do not comprise.
Step 13: state and relevant state variables according to the corresponding AMD PDU of described confirmation renewal forward step 15 to.
The relevant state variables here refers to send the lower boundary and the coboundary of window, i.e. VT (A) and VT (MS).After the affirmation that receives the AMD PDU that SN is equaled VT (A), transmitting end AM RLC entity can upgrade VT (A) among the AMD PDU that is not identified, and the SN of the AMD PDU of SN minimum is default value owing to send window length, so VT (MS) also can change accordingly.Simultaneously, in the affirmation process,, send the window reach, can send new AMD PDU along with the change of VT (A).
Step 14: according to the state of the corresponding AMD PDU of described confirmation renewal, flow process finishes.
The state of AMD PDU generally is defaulted as " unconfirmed ", and the state that this step is specifically upgraded the corresponding A MD PDU of SN institute that carries in the confirmation is " confirming ".
Step 15: judge whether to exist the RLC SDU of transmission success, if, execution in step 16; Otherwise flow process finishes.
For certain RLC SDU, if relative all AMD PDU are identified, then represent this RLC SDU transmission success, the dependency relation of RLC SDU and AMD PDU will be determined when transmitting end AM RLC entity will be converted to one or more AMD PDU from the RLC SDU on upper strata and send and storage.
Step 16: transmitting end AM RLC entity reports transmission success message about the RLC SDU of described transmission success to the upper strata.
As can be seen, in the prior art, for the RLC SDU of transmission success, AM RLC entity transmitting terminal is only after the affirmation that receives the AMD PDU that SN is equaled VT (A), just can notify these RLC SDU of upper strata to be transmitted success, under such treatment mechanism, the SN of relevant AMD PDU greater than VT (A) even RLC SDU be transmitted success, can not be immediately report transmission success message about these RLC SDU to the upper strata, thereby operations such as discharging buffer memory can not in time be carried out according to transmission success message in the upper strata, even the RLC SDU that can retransmit transmission success is to receiving terminal AM RLC entity, for example, in the process of reconstruction of PDCP, may retransmit the RLC SDU that is not in time confirmed, so existing treatment mechanism causes the waste of storage resources and transfer resource easily, thereby the service quality (QoS) of transfer of data is exerted an influence.
