Description
Technical field
The present invention relates to a kind of sending method of message status report, relate in particular to the sending method of message status report of radio link control layer in a kind of Long Term Evolution (LTE, Long Term Evolution) system.
Background technology
Radio Link control (RLC, Radio Link Control) protocol layer is in the Radio interface protocols stack of LTE system, it is a sublayer of layer 2 (L2), be positioned at medium access control (MAC, MediaAccessControl) on the layer, rlc layer is mainly used to provide segmentation and retransmits business, as link control, encapsulation and reorganization, cascade, user data transmission, error correction, protocol error detection and reparation etc.Each RLC entity is operated by Radio Resource control (RRC, Radio Resource Control) configuration and with three kinds of patterns, is respectively:
Transparent mode (TM, Transparent Mode): transmitting terminal does not add any extra control protocol expense and directly forwarding after receiving the high-rise Service Data Unit (SDU, Service Data Unit) that transmits.
Unacknowledged Mode (UM, Unacknowledged Mode): sending entity is at higher layer protocol data units PDU (PDU, Protocol Data Unit) goes up interpolation necessary control protocol overhead and transmit, but do not guarantee to be delivered to peer-entities, and do not use retransmission protocol.Because RLC PDU includes serial number, therefore can detect the integrality of high-rise PDU.
Affirmation mode (AM, Acknowledged Mode): transmitter side transmits after adding the necessary control protocol overhead on the high level data, and can guarantee to be delivered to peer-entities.Because have automatic repeat requests (ARQ, Automatic Repeat reQuest) ability,, promptly notify the RLC entity of opposite end to retransmit this PDU if RLC receives wrong RLC PDU.Owing to include serial number information among the RLC PDU, support order or out of order submit of data to high level.The AM pattern is the mode standard of packet data transmission.
ARQ in the affirmation mode, be to send message status report (Status Report) to transmitting terminal by rlc protocol entity receiving terminal, rlc protocol entity transmitting terminal judges that according to the affirmation of the sequence in the message status report (ACK_SN), sequence (NACK_SN) unconfirmed which PDU has been received end and has acknowledged receipt of, which PDU or PDU fragment need to retransmit, thereby guarantee reliability of data transmission.In 36.322 agreements, the trigger mechanism that rlc protocol entity receiving terminal sends message status report has following two classes:
Rlc protocol entity transmitting terminal triggering mode: rlc protocol entity transmitting terminal is with the RLC head Polling position set of PDU, when rlc protocol entity receiving terminal is whenever received a PDU, find Polling position set if check, think that then it is a polling message, triggers a message status report.After the automatic repeat requests of the mixing of this PDU (HARQ, Hybrid Automatic Repeat reQuest) reorder (Reordering) is finished, then described message status report is sent to rlc protocol entity transmitting terminal.The situation that rlc protocol entity transmitting terminal sends polling message has following three kinds:
1) this PDU is last message that sends in the rlc protocol entity transmitting terminal buffering area;
2) payload user data of rlc protocol entity transmitting terminal transmission reaches the upper limit of the poll (POLL_BYTE) of RRC configuration, or the PDU number that rlc protocol entity transmitting terminal sends reaches the POLL_PDU number upper limit that RRC disposes;
3) the poll retransmission timer (T_poll_restransmit) of rlc protocol entity transmitting terminal configuration is overtime.
Another kind of is that rlc protocol entity receiving terminal triggers: rlc protocol entity receiving terminal message reorder timer (T_reordering) overtime after.
In 36.322 agreements, send too frequent for fear of message status report, take interface-free resources, be provided with a message status report at rlc protocol entity receiving terminal and forbid (T_status_prohibit) timer, start this timer behind message status report of every transmission, at T_status_prohibit timer run duration, forbid sending message status report, no matter the message status report how many times that has been triggered during this period of time need wait for that all T_status_prohibit just can send the next one after overtime.
36.322 specified optional lengths sets at above-mentioned T_poll_restransmit, T_reordering, T_status_prohibit timer in the agreement, but do not had the relation between definite these three timers.These three timers have been born the function of " message status report triggering " and " message status report is forbidden " respectively, if the duration unreasonable allocation may cause a large amount of redundant messages to send through eating dishes without rice or wine to repeat to rlc protocol entity transmitting terminal from rlc protocol entity receiving terminal; Perhaps cause rlc protocol entity receiving terminal not reply message status report for a long time, a large amount of messages of transmitting terminal are trapped in the buffering area of rlc protocol entity transmitting terminal, can't delete, and may cause follow-up packet congestion.
Summary of the invention

Embodiment
Basic thought of the present invention is: by be set the transmission opportunity of message status report, rationally utilize the mechanism that sends about message status report in 36.322 agreements, make rlc protocol entity receiving terminal status report as far as possible efficiently, and suppressed to transmit at the redundant message of rlc protocol inter-entity, improved data transmission efficiency, particularly for the transmission of eating dishes without rice or wine, save bandwidth, improved the level of resources utilization of eating dishes without rice or wine.
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
Fig. 1 is the schematic flow sheet of the sending method of the message status report of radio link control layer of first kind of embodiment of the present invention, among this embodiment, rlc protocol entity receiving terminal only is provided with the message timer that reorders, as shown in Figure 1, the sending method of the message status report of radio link control layer of the embodiment of the invention may further comprise the steps:
Step 101: the message that radio link control entity receiving terminal the is set duration of length of timer that reorder less than the poll retransmission timer of radio link control entity transmitting terminal.
The basic steps that this step suppresses for message status report of the present invention needs to set in transmission system in advance.Why the message length of timer that reorders is set to less value, be based on that the transmit mechanism of the message status report in the radio link control entity considers: after rlc protocol entity transmitting terminal sends the polling message of a Polling position set, start the poll retransmission timer and pick up counting, promptly start T_poll_restranmit; After rlc protocol entity receiving terminal is received this polling message, determine that its Polling position is " 1 ", then need to send the message of message status report to rlc protocol entity transmitting terminal, but have certain requirement its opportunity that sends the message of message status report: rlc protocol entity receiving terminal is in the receiving data packets process, if the sequence number of received packet is discontinuous, then generate the sliding window of message, to start T_reordering this moment, generally can send the message of message status report after sliding window disappears to rlc protocol entity transmitting terminal.For making rlc protocol entity receiving terminal in time report the accepting state of message, but be unlikely to too frequent reporting, thereby just be provided with T_reordering, only when T_reordering is overtime, rlc protocol entity receiving terminal just sends the message of message status report to rlc protocol entity transmitting terminal, receive before the message of described message status report comprises that last sends the response message of message, also comprise the status response message of the data message that some do not receive certainly.After rlc protocol entity transmitting terminal receives the message of described message status report, confirm wherein to include the response message that last sends message, then stop T_poll_restranmit.Certainly, when rlc protocol entity receiving terminal does not start T_reordering if rlc protocol entity transmitting terminal has sent polling message, rlc protocol entity receiving terminal will send the message of message status report immediately.
When step 102:RLC protocol entity transmitting terminal received the message of message status report before the poll retransmission timer is overtime, stop timing to described poll retransmission timer; The overtime fashion of poll retransmission timer does not receive the message of message status report, will retransmit polling message to rlc protocol entity receiving terminal.
Before T_poll_restransmit is overtime, rlc protocol entity transmitting terminal receives the message of described message status report, confirm wherein whether include the response message that last sends message, if there is the last polling message that sends of then explanation correctly to be received, then close T_poll_restransmit, do not send success if there is the last polling message that sends of then explanation, when T_poll_restransmit is overtime, judge current whether have data that the upper strata waits and send out or the re-transmission message of this protocol layer, if have, the data message that the next one is to be sent sends as polling message, and the Polling position that is about to data message to be sent is for " to be sent to rlc protocol entity receiving terminal after " 1 ".If there is not data message to be sent, then the message that last has been sent is retransmitted to rlc protocol entity receiving terminal as polling message.
The duration of T_poll_restransmit is during greater than the duration of T_reordering, even rlc protocol entity receiving terminal has generated the message of message status report, before T_reordering is overtime, can not be sent to rlc protocol entity transmitting terminal immediately yet, only just the message of the message status report of up-to-date generation can be sent to rlc protocol entity transmitting terminal when T_reordering is overtime, it is too frequent to have avoided rlc protocol entity receiving terminal to send the message of message status report.And the duration of T_poll_restransmit is set to the duration greater than T_reordering, thereby avoided rlc protocol entity transmitting terminal to produce the possibility of redundant polling message, thereby can not cause data jamming, save the processing resource of rlc protocol entity transmitting terminal, improved the efficient that rlc protocol inter-entity valid data are handled.
Fig. 2 is the schematic flow sheet of the sending method of the message status report of radio link control layer of second kind of embodiment of the present invention, among this embodiment, rlc protocol entity receiving terminal only is provided with message status report and forbids timer, as shown in Figure 2, the sending method of the message status report of radio link control layer of the embodiment of the invention may further comprise the steps:
Step 201: the message status report that radio link control entity receiving terminal is set is forbidden the duration of length of timer less than the poll retransmission timer of radio link control entity transmitting terminal.
The basic steps similar with step 101, that step 201 suppresses for message status report of the present invention.Why message status report forbids that length of timer is set to less value, be for making rlc protocol entity receiving terminal in time report the accepting state of message equally, avoid it not report for a long time and make rlc protocol entity transmitting terminal retransmit polling message because of T_poll_restransmit is overtime.After rlc protocol entity receiving terminal is provided with T_status_prohibit, after rlc protocol entity receiving terminal receives polling message, can not report the situation of message status report immediately, and when T_status_prohibit is overtime, just send the message of the message status report of up-to-date generation to rlc protocol entity transmitting terminal, receive before the message of described message status report comprises that last sends the response message of message, also comprise the status response message of the data message that some do not receive certainly.After sending the message of message status report, restart T_status_prohibit.
When step 202:RLC protocol entity transmitting terminal received the message of message status report before the poll retransmission timer is overtime, stop timing to described poll retransmission timer; The overtime fashion of poll retransmission timer does not receive the message of message status report, will retransmit polling message to rlc protocol entity receiving terminal.
The duration of T_poll_restransmit is during greater than the duration of T_status_prohibit, even rlc protocol entity receiving terminal has received polling message, before T_status_prohibit is overtime, also can not send the message of message status report to rlc protocol entity transmitting terminal, only when T_status_prohibit is overtime, just send the message of the message status report of up-to-date generation, thereby avoided the message of rlc protocol entity receiving terminal transmission message status report too frequent.And the duration of T_poll_restransmit is set to the duration greater than T_status_prohibit, thereby avoided rlc protocol entity transmitting terminal to produce the possibility of redundant polling message, thereby can not cause data jamming, save the processing resource of rlc protocol entity transmitting terminal, improved the efficient that rlc protocol inter-entity valid data are handled.
Fig. 3 is the schematic flow sheet of the sending method of the message status report of radio link control layer of the third embodiment of the present invention, among this embodiment, rlc protocol entity receiving terminal is provided with reorder timer and message status report of message simultaneously and forbids timer, as shown in Figure 3, the sending method of the message status report of radio link control layer of the embodiment of the invention may further comprise the steps:
Step 301: reorder timer and message status report of the message that radio link control entity receiving terminal is set forbids that length of timer is all less than the duration of the poll retransmission timer of radio link control entity transmitting terminal.
The basic steps similar with step 101, that step 301 suppresses for message status report of the present invention.Reorder timer and message status report of message forbids that length of timer is set to the duration less than the poll retransmission timer, be for making rlc protocol entity receiving terminal in time report the accepting state of message equally, but be unlikely to too frequent, guaranteed that rlc protocol entity transmitting terminal can not send redundant polling message.
Rlc protocol entity receiving terminal receives polling message, determine to need to send the accepting state of message, but owing to be provided with T_status_prohibit and T_reordering, therefore, rlc protocol entity receiving terminal need judge whether T_status_prohibit starts, if start, the message of the transmission message status report of up-to-date generation when T_status_prohibit is overtime then, if T_status_prohibit does not start, then when T_reordering is overtime, send the message of message status report, when T_status_prohibit and T_reordering start simultaneously, even T_reordering is overtime, but when T_status_prohibit is not overtime, still can not send the message of message status report, that is to say, in the case, the message status report that reports because of the overtime need of T_reordering is suppressed.If T_status_prohibit and T_reordering all do not start, then rlc protocol entity receiving terminal receives polling message and promptly reports message status report.
As a kind of preferred scheme, message status report is set forbids that length of timer is less than the message length of timer that reorders, this is to consider that the reorder timing of timer of message needs certain condition just can inspire, in case and message status report is when forbidding that duration that timer is provided with is longer, it is not prompt enough to cause message status to report, thereby may influence rlc protocol entity transmitting terminal the deletion that transmits message is handled, caused redundant message to increase, influence its processing speed.
The timer that preferably message reordered, message timer, the message status report duration relation between the timer of forbidding that reorders that it will be appreciated by those skilled in the art that disposes in the rlc protocol entity of same system by aforementioned requirement.Certainly, at different message status report modes, can adopt the timer duration set-up mode of aforementioned each embodiment.
When step 302:RLC protocol entity transmitting terminal received the message of message status report before the poll retransmission timer is overtime, stop timing to described poll retransmission timer; The overtime fashion of poll retransmission timer does not receive the message of message status report, will retransmit polling message to rlc protocol entity receiving terminal.
Step 302 is identical with the processing mode of step 102, repeats no more here.
The duration of T_poll_restransmit is during greater than the duration of T_status_prohibit and T_reordering, even rlc protocol entity receiving terminal has received polling message, before T_status_prohibit or T_reordering are overtime, also can not send the message of message status report to rlc protocol entity transmitting terminal, and the setting of T_status_prohibit, guaranteed as long as in the T_status_prohibit timing course, satisfied the condition of structure message status report message, even then rlc protocol entity receiving terminal does not produce the message sliding window and starts T_reordering, also can when T_status_prohibit is overtime, send the message of message status report to rlc protocol entity transmitting terminal.Avoided the message frequency of rlc protocol entity receiving terminal transmission message status report too low, can be too not frequent yet; Also avoid rlc protocol entity transmitting terminal to produce the possibility of redundant polling message, thereby can not cause data jamming, saved the processing resource of rlc protocol entity transmitting terminal, improved the efficient that rlc protocol inter-entity valid data are handled.
Consider that message sends mechanism in general system data transmission rate and 36.322 agreements, the duration reference value of T_status_prohibit, T_status_prohibit and T_reordering is respectively 300ms, 100ms and 200ms, concrete numerical value can be set in conjunction with concrete system transmissions speed and system requirements, as long as satisfy the condition that is provided with of above-mentioned timer duration.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
