Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of jamming control method and device.
Background technology
The congested control of transport network layer (TNL, Transport Network Layer), the transport layer that is used to control interface (Iub mouth) between radio network controller (RNC) and base station (Node-B) is congested.The RNC of Iub mouth and Node-B have two kinds of connected modes, and transport layer protocol can be based on the ATM(Asynchronous Transfer Mode) mode, also can be based on the IP mode.If based on the ATM mode, adopt direct-connected connected mode between RNC and the Node-B, then the bandwidth between RNC and the Node-B is a fixed configurations, the congested situation of TNL can not occur.If based on the IP mode, adopt the connected mode of route switching between RNC and the Node-B, when a plurality of inlet flows arrive a router, and the output stream of router is during less than the summation of these inlet flows, and it is congested TNL then to occur.When certain logic entity stream (MAC-d flow) of being responsible for handling the media access control layer of the designated lane (DCH) of distributing to UE under the connection mode TNL takes place when congested, need to reduce the data volume of this MAC-d flow, then the scheduler module of media access control layer (MAC layer) need reduce the interface-free resources of distributing to this MAC-d flow, because the scheduling of MAC is based on subscriber equipment (UE), so reduce the interface-free resources of distributing to the UE that comprises this MAC-d flow.
3GPP 25.902 agreements (Release 6) regulation inserts in (HSUPA) system in High Speed Uplink Packet, and RNC is responsible for detecting congested control, and by the congested indication control frame notice Node-B in the Frame Protocol (FP), Node-B carries out concrete congested control.
RNC can detect congested by dual mode, and by the notice of the congested indication control frame among FP Node-B, wherein, the information that congested indication control frame comprises is divided into three kinds: " congested-detect frame losing ", " congested-detect time delay " and " not congested ".
After Node-B received the congested indication control frame of RNC, Node-B need reduce the bit rate of Iub mouth, and concrete operations comprise:
1) if Node-B receives congested indication, for example " congested-detect frame losing " or " congested-detect time delay ", Node-B needs to reduce at least the bit rate that congested MAC-d flow takes place.
2) if Node-B receives the indication of " not congested ", Node-B need return to normal condition gradually.
3) if Node-B does not receive any congestion state indication some seconds under congestion state, then Node-B can return to normal condition gradually.
Congestion detection algorithm is carried out at RNC, and congestion avoidance algorithm carries out at Node-B, can minimization system congested.The scheduling of HSUPA system is carried out at Node-B, and the congested control of TNL layer of RNC and Node-B can provide better service quality (QoS, Quality ofService) end to end to the user, and reduces overhead.Because the Iub mouth is congested, cause the Loss Rate of packet to increase, can trigger high-rise more data like this retransmits, such as Radio Link control (RLC, Radio LinkControl) layer and transmission control protocol (TCP, Transmission Control Protocol) Ceng re-transmission can cause the decline of increase, resource waste and the systematic function of loading like this.For fear of this situation, it is congested and control TNL is congested that the TNL congestion control mechanism need detect the TNL of Iub mouth.Congestion detection mechanism can be based on the detection of time delay or packet loss.
The at present common congested control flow of TNL as shown in Figure 1, Node-B safeguards the state of UE, the set of UE is divided into congested subclass and non-congested subclass, Node-B adds congested subclass or non-congested subclass according to the indication in the congested indication control frame of receiving with UE.Node-B once dispatches every 5 milliseconds (ms), at first determine UE to be scheduled, and definite residing set of this UE, for the UE in the congested subclass, Node-B is according to min (the actual cache size of safeguarding, the resource of being distributed during last scheduling can data carried by data size/2) carry out resource allocation, be Node-B when selecting current reality to safeguard the cache size of this UE and last scheduling of resource for resource that this UE distributed can data carried by data amount/2 in less value, determine current resource for this UE distribution.For the UE in the non-congested subclass, the resource that Node-B distributes for this UE according to the cache size of current actual this UE that safeguards.
Yet, though prior art can limit the data volume of eating dishes without rice or wine that congested MAC-d flow takes place by the maximum allocated resource that reduces in the resource allocation when generation TNL is congested, the size of the data volume of control Iub mouth, thus control TNL is congested.But, during relieve congestion is handled, after receiving not congested indication (being relieve congestion), revert to normal condition immediately, promptly immediately UE is added non-congested subclass, the cache size of this UE that safeguards according to reality immediately when resource allocation is the resource of this UE distribution, and it is congested to cause occurring TNL once more, it is congested and separate vibration repeatedly between congested thereby TNL to occur, and has increased the signaling consumption of Iub mouth.
In addition, because TNL is congested mainly is that the transport layer of bottom is congested, if transport layer is a Transmission Control Protocol, then the TNL relieve congestion need be in conjunction with the slowstart algorithm of Transmission Control Protocol, be that the TCP layer does not return to congested preceding data volume immediately, the data volume of TCP layer increases according to exponential form.May occur thus in the TNL relieve congestion process, the data volume grow speed of MAC layer is higher than the data volume grow speed of TCP layer, thereby causes in the TNL relieve congestion process taking place new congested.
In sum, the TNL congestion control mechanism of prior art can't avoid TNL congested and separate vibration repeatedly between congested, has increased the signaling consumption of Iub mouth, and may take place new congestedly in TNL relieve congestion process, causes systematic function to descend.

Embodiment
The embodiment of the invention provides a kind of jamming control method and device, and is congested and separate vibration repeatedly between congested in order to avoid TNL, thereby reduced the signaling consumption of Iub mouth, and avoids taking place new congested in TNL relieve congestion process, improves systematic function.
The problem that the embodiment of the invention exists at existing TNL congestion control scheme, the congested control of effective solution: TNL has been proposed at the data transmission resources of distributing to UE, the adjustment mode that the minimizing of the employing property taken advantage of, additivity increase, after keeping the stable transfer of a period of time, increase to distribute bandwidth more gradually, thereby avoid TNL congested and separate vibration repeatedly between congested; And, in the relieve congestion process,, return to normal condition gradually, thereby in TNL relieve congestion process, avoid taking place new congested in conjunction with the relieve congestion time of TCP layer and the congestion detection mechanism of RNC, reach the congested purpose of effective control TNL.
In the embodiment of the invention, in advance in base station (Node-B) for UE is provided with three set, be respectively non-congested set, congested set, incomplete congested set.UE in the non-congested set is in non-congestion state, and it is congested that promptly TNL does not take place the data flow of current UE; UE in the congested set is in congestion state, and promptly that TNL has taken place is congested for the data flow of current UE; UE in the incomplete congested set is in incomplete congestion state, and promptly the data flow of current UE is in the process of recovering gradually from TNL is congested.
After Node-B received the congested indication of TNL, congested indication added congested set with corresponding UE according to TNL in meeting; And after Node-B receives TNL relieve congestion indication, can corresponding UE be added incomplete congested set (rather than immediately UE being added congested set) earlier according to the indication of TNL relieve congestion, the data transmission resources that distributes for the UE in this incomplete congested set can little by little increase, after increasing to a certain degree, again UE is added non-congested set, for the UE in the non-congested set, be this UE distribute data transfer resource according to the cache size of UE reality.Wherein, because the real-time cache size to base station report self reality of UE meeting, so base station maintenance has the real cache size of UE.
Below in conjunction with accompanying drawing the technical scheme that the embodiment of the invention provides is described.
Referring to Fig. 2, the overall flow of the congested control of a kind of TNL that the embodiment of the invention provides comprises step:
S 101, RNC carry out packet loss detection, if detect the LOF of N continuous frame data, the frame number in the FP Frame that even receives (FSN, Frame Sequence Number) differs the N frame with the FSN that expectation receives, it is congested to determine that then TNL has taken place, and sends the congested indication of TNL to Node-B.
Wherein, N is the integer more than or equal to 1, and concrete value can be provided with according to actual needs.In the congested indication of TNL, comprise the congested pairing UE information of data flow of TNL that taken place.
RNC also can judge that whether TNL to take place congested by other modes, for example by time delay detection etc.
After S102, Node-B receive the congested indication of TNL,, the intermediate variable TBTNL=TBUE/a of this UE correspondence is set according to the UE information that comprises in the congested indication of this TNL; Node-B when carrying out resource allocation, according to min{TBTNL, the real cache size of UE } determine the size of the data transmission resources that need distribute for this UE.
Wherein, the intermediate variable TBTNL of UE correspondence is meant the intermediate variable of the size that is used to be adjusted into the data transmission resources that this UE distributes.It is congested to the process of relieve congestion from the data flow of UE TNL to take place, and the TBTNL by this UE correspondence is restricted to the resource size that this UE distributes.
When UE was in non-congested set, the value of TBUE equaled the size of transmission block maximum in the actual transmissions piece of this UE among the statistic window W; When UE was in congested set or incomplete congested set, the value of TBUE equated with the value of TBTNL.
Statistic window W, the statistic window that promptly sets in advance is used for adding up the maximum transmission block (TB) of actual transmissions piece of receiving UE in the nearest statistic window W.After the congested indication of TNL was received in the base station, the size of maximum TB was the value of TBUE in the statistic window W.
Wherein, a is the integer greater than 1, and 1/a is the minimizing ratio of intermediate variable TBTNL.That is to say that by the adjustment of parameter a to the minimizing of the TBTNL property taken advantage of, the feasible adjustment of distributing to the data transmission resources of UE keeps stable.
S103, if RNC detect the situation that admission control does not appear in continuous L frame, then send the TNL relieve congestion and indicate to Node-B, Node-B recovers gradually, promptly makes TBTNL=TBTNL+TBUE/b at set intervals, up to returning to non-congestion state fully.Wherein, L is the integer more than or equal to 1.
Comprise the congested pairing UE information of data flow of TNL of having removed in the indication of TNL relieve congestion.
Congested indication of TNL and the indication of TNL relieve congestion all are to carry by the congested indication control frame among the FP, also all are the indications of making at the data flow state of some UE therefore.
Wherein, b is the integer greater than 1, and 1/b is the scaling up of intermediate variable TBTNL.That is to say, by parameter b TBTNL is carried out the adjustment that additivity increases, the feasible adjustment of distributing to the data transmission resources of UE keeps stable.
Below at how realizing that in concrete congested control procedure congested the recovery gradually of TNL describes in detail.
In the congested control of the TNL that the embodiment of the invention provides, UE is divided into congestion state, incomplete congestion state, three kinds of states of non-congestion state.
In embodiments of the present invention, set in advance two kinds of counter C1 and C2, and timer T1 is set in base station side.
UE is transformed into the condition of incomplete congestion state by congestion state, if just receive the TNL relieve congestion indication of RNC, then Rule of judgment is too single, needs to increase Rule of judgment.And the purpose of counter C1 is set, just in order to prevent that the base station from should receive but do not receive TNL relieve congestion indication, for example, RNC has sent the indication of TNL relieve congestion, but may be because link failure, cause the base station not received, perhaps the RNC self reason causes should send the indication of TNL relieve congestion but send etc., then can cause Node-B this UE can't be returned to non-congestion state.Therefore, the frame number that admission control does not appear in counter C1 statistics continuously is set, come congested whether releasing of the TNL that data flow took place of monitoring UE, if the frame number of counter C1 statistics surpasses certain value, then the base station is thought that the TNL that data flow took place of UE is congested and has been removed, and can revert to the stock number that this UE distributes gradually.This shows, when UE enters congested set, need enabling counting device C1, when UE leaves congested set, need stop counter C1.It is UE is transformed into incomplete congestion state by congestion state condition, be to receive that the TNL relieve congestion indication of RNC or counter C1 counting finish, these two conditions satisfy one of them, determine all that the TNL that data flow took place of UE is congested and removed that UE need be transformed into incomplete congestion state by congestion state.
The purpose of counter C2 is set, and it is congested to be whether data flow for monitoring UE TNL takes place.The purpose of timer T1 is set, and is the retention time for the intermediate variable of monitoring UE correspondence, i.e. time of not changing of the value of the intermediate variable of monitoring UE correspondence.
Counter C2 and timer T1 are to be applied in the congested process of removing gradually of TNL, promptly at be the UE that is in the incomplete congested set.When UE enters incomplete congested set, need enabling counting device C2 and timer T1.When UE leaves incomplete congested set, need stop counter C2 and timer T1.
Because TNL is congested mainly is transport layer congested of bottom, need reduce the interface-free resources of distributing to UE at the MAC layer, therefore the TNL congestion control mechanism should combine with the congestion control mechanism of transport layer, if the agreement that transport layer adopts is a Transmission Control Protocol, because the relieve congestion process need is in conjunction with the slowstart algorithm of Transmission Control Protocol, be that TCP layer in the relieve congestion process can't return to the data volume of TNL before congested immediately, institute's data recovered amount increases according to exponential form, therefore the data volume grow speed of MAC layer need be lower than the data volume grow speed of TCP layer, just can not cause taking place in the process of relieve congestion new congested.Therefore, in the congested process of removing gradually of the TNL in the embodiment of the invention, need be complementary with the congestion control mechanism of bottom transport layer.That is to say,, therefore timer T1 is set in order to realize collaborative work high-rise and transport layer.
In the relieve congestion process, use timer T1, be used for remaining the constant time of a certain value at the congested process record TBTNL that removes gradually.The value of TBTNL remains unchanged, and then Gao Ceng data volume can not continue to increase, and when timer T1 was overtime, the value of TBTNL just can further increase, and makes high-rise data volume further increase.And the overtime time of experiencing of high-rise waiting timer T1 promptly is the needed time of relieve congestion process of transport layer, thereby has realized collaborative work high-rise and transport layer.
Timing value and the transport layer of timer T1 have relation, if transport layer is User Datagram Protoco (UDP) (UDP, User Datagram Protocol) pattern, then the timing value of T1 can be set to 0, if transport layer is the TCP pattern, then owing to startup slowly and the congestion control mechanism of TCP, the needed time of relieve congestion process of TCP is long, and the timing value that T1 can be set is the Loop Round Trip Time (RTT) of TCP.
Node-B is in the congested process of removing gradually of TNL, increase TBTNL gradually, after Node-B increases TBTNL, if it is congested that RNC does not detect TNL, Node-B just can continue to increase TBTNL, and RNC judges that the congested mechanism of TNL is if the N continuous frame detects admission control, thinks that then TNL takes place gathers around base.Therefore, in congested releasing process gradually, introduce counter C2, in order in congested releasing process gradually, the number of times of the FP frame of the congested data flow transmission of TNL takes place in record UE, with at the medium access control entity MAC-e protocol Data Unit (PDU that eats dishes without rice or wine to receive this UE, ProtocolData Unit) has only schedule information (SI in, Scheduling Information) number of times and, when this with when reaching the threshold value that sets in advance, add the time delay (being 30ms) of Iub mouth, think that then counter C2 counting finishes.If Node-B the congested indication of TNL of not receiving RNC, can think simply then that TNL does not during this period of time take place was congested before C2 counting is finished, can further increase the interface-free resources of distributing to this UE.
Wherein, statistics eats dishes without rice or wine to receive the number of times that has only SI among the MAC-e PDU of UE, is too small in order to prevent TBTNL, makes when the resource of being distributed can't be carried a PDU, causes congested situation about can't remove.
Referring to Fig. 3, the Node-B that the embodiment of the invention provides receives that the handling process after the congested control indication of the TNL of RNC transmission is as follows:
At first, Node-B judges that the type of the congested control indication of TNL that RNC sends is congested indication of TNL or the indication of TNL relieve congestion.
When Node-B determine to receive be the congested indication of TNL the time, according to the UE information that comprises in the congested indication of this TNL, judge the set under this UE; When the set under determining this UE is non-congested set, the 1/a of the interior maximum transmitted piece of statistic window W that the intermediate variable TBTNL of this UE correspondence equals to set in advance is set, i.e. TBUE/a; And, this UE is added congested set; When the set under determining this UE is congested set, the value of the intermediate variable TBTNL of this UE correspondence is adjusted into original 1/a, i.e. TBTNL=TBTNL/a; When the set under determining this UE is incomplete congested set, this UE is added congested set, the value of the intermediate variable TBTNL of this UE correspondence is adjusted into original 1/a, and the data flow that stops to monitor retention time of intermediate variable TBTNL of this UE correspondence and this UE whether TNL to take place congested, promptly stop timer T1 sum counter C2.
When Node-B determine to receive be the indication of TNL relieve congestion the time, according to the UE information that comprises in this TNL relieve congestion indication, determine the set under this UE.When the set under this UE is congested set, stop to monitor congested whether releasing of the TNL that data flow took place of this UE, promptly stop counter C1, this UE is added incomplete congested set, and the data flow of monitoring retention time of intermediate variable TBTNL of this UE correspondence and this UE whether TNL to take place congested, promptly start timer T1 sum counter C2.And, make TBTNL=TBTNL+TBUE/b.When the set under this UE is non-congested set or incomplete congested set, this TNL relieve congestion indication is defined as invalid indication.
Referring to Fig. 4, the Node-B that the embodiment of the invention provides is that the handling process of UE Resources allocation is as follows:
At first determine UE to be scheduled, judge the residing set of this UE then.
For the UE in the non-congested set, Node-B is this UE distribute data transfer resource according to the real cache size of UE.
For the UE in the congested set, Node-B is this UE distribute data transfer resource according to the intermediate variable TBTNL of this UE correspondence, promptly according to min{TBTNL, and the real cache size of UE } be this UE distribute data transfer resource; And, monitor congested whether releasing of the TNL that data flow took place of this UE, judge promptly whether counter C1 counts and finish, when counter C1 counting is finished, when promptly determining the TNL relieve congestion that data flow took place of this UE, this UE is added incomplete congested set, and the data flow of monitoring retention time of intermediate variable TBTNL of this UE correspondence and this UE whether TNL to take place congested, promptly start timer T1 sum counter C2.
For the UE to be dispatched in the incomplete congested set, the mode that Node-B adopts additivity to increase increases the data transmission resources that distributes for this UE gradually.Particularly:
Node-B judges whether the intermediate variable TBTNL of UE correspondence keeps a period of time do not changed (judging promptly whether timer T1 is overtime), and whether the data flow of judging this UE TNL congested (promptly judge whether counter C2 counts finish) does not take place, surpass the very first time when the retention time of the intermediate variable of determining the UE correspondence, and TNL does not take place when congested in the data flow of this UE, the intermediate variable TBTNL of this UE correspondence is increased by first percentage, even TBTNL=TBTNL+TBTNL/b, and whether the big or small TBINIT of the maximum transmitted piece of TNL when congested takes place in the intermediate variable TBTNL that judges the current correspondence of this UE more than or equal to the data flow of this UE, if, illustrate that then UE reverts to non-congestion state, this UE is added non-congested set, and, be this UE distribute data transfer resource according to the real cache size of this UE; Otherwise, illustrate that UE does not also revert to non-congestion state fully, still be in incomplete congestion state, restart timer T1 sum counter C2, and the size of the real cache of the intermediate variable TBINIT of this UE correspondence and this UE relatively, select the size of less value as the current data transmission resources that distributes for this UE, promptly according to min{TBTNL, the real cache size of UE } be this UE distribute data transfer resource.
There is not overtime and/or counter C2 not have in time that counting finishes at timer T1, when being the UE Resources allocation, need be according to min{TBTNL, the real cache size of UE } be this UE distribute data transfer resource.
