Description
Technical field
The present invention relates to the network communications technology field, be specifically related to a kind of ABIS reverse interface jamming control method and transceiver base station.
Background technology
In the wireless mobile telecommunication technology of low speed, the speed of eating dishes without rice or wine generally is the bottleneck of communication, so the speed of eating dishes without rice or wine is the emphasis of congested control and bandwidth optimization.
In (cdma2000 1x-RTT EVolution to packet Data Optimized services), reverse data flows to: AT (Access terminal, access terminal)-BTS (Base TransceiverStation, transceiver base station)-BSC (Base Station Controller, base station controller)-PCF (data service control function module)-core net.Reversed peak speed can reach 1.8Mbps because single user eats dishes without rice or wine, so the interface bandwidth of ABIS (interface between BTS and the BSC) also may become the bottleneck of communication.
Because it is relatively more expensive that the transfer of data of ABIS interface realizes cost, as adopting transmission means transmission data such as microwave, satellite, therefore, rational and effective makes full use of the ABIS interface bandwidth and just seems extremely important.
AT-〉BTS-〉reverse data of BSC flows to schematic diagram as shown in Figure 1.
Among Fig. 1, BTS receives the data that AT transmission comes by eating dishes without rice or wine, and according to the priority of data data is put into corresponding formation, and then, BTS is according to certain dispatching algorithm, reading of data from formation, and send the data to BSC by the ABIS interface.
If with BTS is that the buffer size of a traffic flow assignment is called buffer length, data quantity stored in a certain moment buffering area is called queue length, so, under normal conditions, queue length should be less than buffer length.When buffer length is equal with queue length, if still have data to arrive BTS, will cause the buffering area of BTS to overflow, BTS can abandon its packet that newly receives.
As can be seen from Figure 1, when the speed of eating dishes without rice or wine surpassed the ABIS interface bandwidth, the Business Stream corresponding queues length that some formation of BTS such as priority are lower will increase, and when formation was overflowed, BTS have to abandon the data that the back receives.The instantaneous speed of eating dishes without rice or wine surpasses the ABIS interface bandwidth and can not cause the BTS formation to overflow, and still, when the speed of eating dishes without rice or wine continues to surpass the ABIS interface bandwidth in a long time, just may cause the BTS formation to overflow.In data transmission procedure, if situations such as traffic peak, data burst, part A BIS interface transmission fault all can cause bandwidth deficiency in ABIS interface bandwidth deficiency or short time, thereby cause ABIS reverse interface flow congestion.At this moment,, can cause the buffering area of BTS to overflow, cause the data packet loss if do not carry out suitable control.
When the upper strata host-host protocol is when being similar to the agreement of TCP, the method for avoid the BTS packet discard, alleviating ABIS reverse interface flow congestion mainly contains two kinds:
Method one: TCP can start slowstart algorithm and congestion avoidance algorithm because of the packet loss of BTS, thereby alleviates ABIS reverse interface flow congestion.
In the method one, the BTS packet discard can cause overtime re-transmission, and can start and start slowly and congestion avoidance algorithm, the data that BTS abandons can cause RLP (Radio Link Protocol, radio link protocol) retransmit, the data of re-transmission are not only wasted interface-free resources, also can increase the congested pressure of ABIS interface, and startup and Congestion Avoidance have had a strong impact on the throughput of system slowly.
Method two: when the ABIS interface occur congested after, BTS sends broadcast, notifies all AT with the maximum transmission rate that system allows, thereby controls the transmission rate of all AT, limits the reverse rate of eating dishes without rice or wine, and slows down and further eliminates the congested of ABIS interface; After ABIS interface congestion situation was eliminated, BTS sent broadcast, recovers the maximum transmission rate of all AT.
In the method two, the BTS packet discard can cause overtime re-transmission equally, and the data of re-transmission have been wasted interface-free resources, increased the congested pressure of ABIS interface, simultaneously, because the transmission of broadcast needs certain delay, so congestion situation will continue in the time of this section delay.And, limit the maximum transmission rate of all AT, perhaps the packet that receives after congested back BTS abandons all can not provide difference service quality for the high user of priority.When BTS started congested control, all AT can reduce transmission rate simultaneously, and after the congested elimination, all AT can improve transmission rate again simultaneously, may make the frequent startup of BTS, stop congested control procedure, thereby cause the vibration of system.
When the upper strata host-host protocol when being similar to UDP or stream media protocol, not abandoning of packet can feed back to transmitting terminal, like this, ABIS interface congestion situation can not get alleviating and avoiding, and, the data that BTS abandons can not cause data re-transmission, thereby cause loss of data, in business such as VOIP, VT, continuous speech frame or frame of video abandon, can seriously reduce service quality, influence user's impression.
In a word, no matter the upper strata host-host protocol is to be similar to UDP or stream media protocol, still to be similar to the agreement of TCP, all can't avoid the phenomenon of BTS packet discard, in wireless mobile application, interface-free resources is a resource more in short supply, and BTS abandons the data that receive, and has wasted interface-free resources.That is to say that in the not reduction of transmitting power of AT, promptly under the undiminished situation of reverse interference, the throughput of system's reality has descended, thereby has reduced the utilance of interface-free resources.

Embodiment
If when the ABIS reverse interface does not also reach congested and is about to reach congested, the ABIS reverse interface is carried out congested control and treatment, promptly in advance the ABIS reverse interface is carried out congested control and treatment, then data packet loss phenomenon can be effectively avoided, thereby many disadvantages such as waste interface-free resources that factor causes according to packet loss, user satisfaction difference can be avoided.
Therefore, core of the present invention is: the pre-congested control thresholding of ABIS reverse interface is set, transceiver base station BTS detects ABIS reverse interface Congestion Level SPCC, and BTS surpasses pre-congested control gate in limited time at definite ABIS reverse interface Congestion Level SPCC, and the ABIS interface is carried out congested control and treatment.
The present invention at first needs for the ABIS reverse interface pre-congested control thresholding to be set, pre-congested control thresholding should guarantee to reach pre-congested control gate in limited time at the Congestion Level SPCC of ABIS interface, it is congested that the ABIS reverse interface does not also reach, that is to say, when the Congestion Level SPCC of ABIS interface reaches pre-congested control gate in limited time, BTS also can not carry out the data packet loss to be handled.
The setting of pre-congested control thresholding is corresponding with the method that BTS detects ABIS reverse interface Congestion Level SPCC, and as when pre-congested control thresholding is set to ABIS interface bandwidth occupancy thresholding, BTS need detect ABIS interface bandwidth occupancy; When pre-congested control thresholding was set to BTS traffic stream queues length threshold, BTS need detect BTS traffic stream queues length; When pre-congested control thresholding was set to BTS Business Stream buffer performance thresholding, BTS need detect BTS Business Stream buffer performance.Pre-congested control thresholding among the present invention can comprise one or more in the above-mentioned thresholding simultaneously, and when pre-congested control thresholding comprised a plurality of in the above-mentioned thresholding, the testing process of BTS also should comprise corresponding a plurality of.
When determining its detected ABIS reverse interface Congestion Level SPCC, BTS reaches pre-congested control gate in limited time, should adopt the methods such as transmission rate that reduce AT that the ABIS reverse interface is carried out congested control and treatment, make ABIS reverse interface Congestion Level SPCC be lower than pre-congested control thresholding.For avoiding the frequent startup of BTS, stopping congested control procedure, avoid the vibration of system, the present invention also is provided with the pre-congested control cancellation thresholding of ABIS reverse interface, and the value of oppositely pre-congested control cancellation thresholding should be less than the value of pre-congested control thresholding.At BTS the ABIS reverse interface is carried out in the congested control and treatment process, be no more than oppositely pre-congested control cancellation thresholding if BTS detects the reverse blockage degree of ABIS interface, then BTS should cancel reverse blockage control and treatment process.
The method of transmission rate that reduces AT is as being set to RAB (Reverse Activity indication) busy condition, being predetermined value such as minimum value with the threshold setting of RAB, and the access message of restriction AT sends frequency, adjust the reverse MAC layer parameter of being scheduled to the AT Business Stream etc.The present invention can adopt above-mentioned any method to reduce the transmission rate of AT, also can be when adopting wherein the method for the transmission rate of a kind of AT of reduction not make the reverse blockage degree of ABIS interface be no more than oppositely pre-congested control cancellation thresholding, adopt wherein other a kind of method to continue to reduce the transmission rate of AT again, when successively adopting above-mentioned two kinds of methods still not make the reverse blockage degree of ABIS interface be no more than oppositely pre-congested control cancellation thresholding, can adopt the third method to reduce the transmission rate of AT again.The present invention can adopt RAB to be set to busy condition earlier, be the method for predetermined value such as minimum value with the threshold setting of RAB, when this method of employing does not achieve the goal, adopt the method for the access message transmission frequency of restriction AT again, if still do not achieve the goal, adopt the method for the reverse MAC layer parameter of adjusting predetermined AT Business Stream again.
Below ABIS reverse interface jamming control method of the present invention is described in detail.
The invention provides the method for three kinds of tolerance ABIS reverse interface Congestion Level SPCCs.
Method one: detect ABIS interface bandwidth occupancy.
The sense cycle of setting BTS is T, in this cycle, eat dishes without rice or wine reverse Mean Speed Rairave should for BTS in the sense cycle T from all data volumes of eating dishes without rice or wine to receive and the ratio of sense cycle T.Setting the ABIS interface bandwidth is Rabis, then ABIS interface bandwidth occupancy=Rairave/Rabis.The present invention can be provided with sense cycle T according to the actual conditions of network, and ABIS interface bandwidth occupancy should be between 0~1, and ABIS interface bandwidth occupancy approaches 1 more, and it is congested to illustrate that the ABIS reverse interface approaches more.Pre-congested control thresholding is that ABIS interface bandwidth occupancy thresholding should be less than 1.
The instantaneous reverse rate of eating dishes without rice or wine surpasses the ABIS interface bandwidth and is fine, and still, the reverse Mean Speed Rairave that eats dishes without rice or wine can not surpass ABIS interface bandwidth Rabis, and the reverse rate of promptly eating dishes without rice or wine can not continue to surpass ABIS interface bandwidth Rabis in the long period section.
Method two, detection BTS traffic stream queues length.
If BTS scheduling time negligible words, the overflowing of any traffic stream queues among the BTS, it is congested to illustrate that all the ABIS reverse interface occurs, so, adopt and detect BTS traffic stream queues length and can be used as the tolerance that detects ABIS reverse interface Congestion Level SPCC.BTS traffic stream queues length approaches the length of Business Stream buffering area more, and it is congested to illustrate that the ABIS reverse interface approaches more.Pre-congested control thresholding is that BTS traffic stream queues length threshold should be less than the length of Business Stream buffering area.
Method three, detection BTS Business Stream buffer performance.
Because the length of the buffering area of each Business Stream may there are differences among the BTS, so, the threshold value of each Business Stream correspondence may there are differences, for making things convenient for BTS to pre-congested judging process, the present invention can define BTS Business Stream buffer performance for Business Stream, BTS Business Stream buffer performance=BTS traffic stream queues length/BTS Business Stream buffer length.Like this, the BTS Business Stream buffer performance threshold value of each traffic stream queues correspondence can be unified.BTS Business Stream buffer performance should be between 0~1, and BTS Business Stream buffer performance approaches 1 more, and it is congested to illustrate that the ABIS reverse interface approaches more.Pre-congested control thresholding is that BTS Business Stream buffer performance thresholding should be less than 1.
Detect utilizing above-mentioned testing process to carry out Congestion Level SPCC, and after triggering congested control and treatment process, be called the reflection time during this period of time to what congested control was had an effect, in the reflection time, BTS should make traffic stream queues length no longer increase.
If BTS Business Stream buffering area is less, the data of eating dishes without rice or wine in the reflection time can be full of it, perhaps the buffer data that is full of in the reflection time can send and finish, then be not suitable for weighing ABIS interface congestion degree with the third method with second, that is to say, if Business Stream concurrent among the BTS is a lot, and the buffer length of each Business Stream is less, then should select first method to detect ABIS reverse interface Congestion Level SPCC, otherwise, can select second kind and the third method to detect ABIS reverse interface Congestion Level SPCC.
Be example with ABIS interface bandwidth occupancy, BTS streambuf occupancy below, to the algorithm of the congested control of ABIS reverse interface of the present invention, promptly the congested control procedure of ABIS reverse interface describes.
The pre-congested control gate limit value of setting ABIS interface bandwidth occupancy and BTS streambuf occupancy correspondence is AbisOverFlowThresh, and the pre-congested control cancellation threshold value of ABIS interface bandwidth occupancy and BTS streambuf occupancy correspondence is AbisStableThresh.The AbisStableThresh here should be less than AbisOverFlowThresh.
When ABIS interface bandwidth occupancy or BTS streambuf occupancy surpassed AbisOverFlowThresh, BTS triggered the congested control procedure of ABIS reverse interface, the restriction reverse transmission rate of eating dishes without rice or wine.
In the congested control procedure of ABIS reverse interface, if BTS detects ABIS interface bandwidth occupancy or BTS Business Stream buffer performance when being lower than AbisStableThresh, cancel congested control procedure, thereby, under the situation that makes full use of the ABIS interface bandwidth, avoided BTS to start, stop the phenomenon of congested control procedure repeatedly.
The congested control procedure of ABIS reverse interface can be divided into following several steps and carry out:
Step 1,, BTS surpasses AbisOverFlowThresh when detecting ABIS reverse interface Congestion Level SPCC, that is to say, when triggering the congested control of ABIS reverse interface, at first need to adjust the RAB of sector, RAB is set to " busy ", comes requirement AT to reduce transmission rate.RAB is the sector-level parameter, and all AT under the sector are worked.AT based on Rev0 (protocol reversion 0, protocol version 0) handles according to the reduction of speed that the rate transitions matrix carries out transmission rate; AT based on RevA (protocol reversion A, protocol version A) handles according to the reduction of speed that reverse MAC layer algorithm carries out transmission rate.The present invention can be by being provided with different state-transition matrixes or reverse MAC layer parameter to different AT, different Business Streams, the business that realizes controlling different priorities reduces the amplitude of transmission rate, thereby can provide differentiated service features for high-priority service, guarantee the service quality of high-priority service.
When BTS cancelled congested control and treatment process, BTS was provided with RAB according to the reverse load of eating dishes without rice or wine, if the reverse load of promptly eating dishes without rice or wine is not high, then RAB is set to " no busy ", so all AT recover its transmitting power and data transmission rate under this sector.
When the ABIS interface can not directly be provided with the value of RAB, can limit the transmission rate of AT under this sector by the thresholding that RAB is set, promptly when starting the congested control and treatment process of ABIS reverse interface, the threshold value of RAB is set to minimum value, like this, ROT (end make an uproar lifting, rise over thermal) is easy to surpass this thresholding, thereby makes BTS RAB be set to " busy ".Equally, when BTS cancels congested control and treatment process, can be by recovering the threshold value of RAB, make BTS the value of RAB is set according to reverse ROT (Rise OverThermal), RAB is set to " no busy ".
When the method in adopting step 1 can not make the detected ABIS reverse interface of BTS Congestion Level SPCC be no more than AbisStableThresh, need to step 2.
If a large amount of AT of step 2 register simultaneously, initiate a session request or connection request, a large amount of access message also can impact to ABIS reverse interface service traffics, as at system upgrade, when holding activity, morning start etc., can impact to ABIS reverse interface service traffics.Like this, when the ABIS interface was carried out congested control and treatment, the access message that also needs suitably to limit AT sent frequency, to guarantee the access of high priority AT.
When the method in adopting step 1 and step 2 can make the detected ABIS reverse interface of BTS Congestion Level SPCC be no more than AbisStableThresh, need at first cancel AT and insert the restriction that message sends frequency, then, recover the setting of RAB again.
When the method in adopting step 1 and step 2 still can not make the detected ABIS reverse interface of BTS Congestion Level SPCC be no more than AbisStableThresh, need to step 3.
If the priority of the Business Stream of the current activation of step 3 is all than higher, when making ABIS reverse interface Congestion Level SPCC still surpass AbisStableThresh by RAB and restriction AT access message transmission frequency are set, then need the optionally reverse MAC layer parameter of adjusting portion separate service stream, with the transmitting power of reduction part A T, thereby reduce the transmission rate that corresponding business flows.
The present invention can start congested control and treatment process at Business Stream buffer performance the best part Business Stream.Concrete grammar is: initiate the parameter-negotiation procedure at intended service stream with AT by AN, by reducing the parameters such as T2PInFlow of AT, limit the transmitting power of AT.
Because when BTS sends data by the ABIS interface, be to dispatch according to the priority of each Business Stream, so, the Business Stream of Business Stream buffer performance maximum also is the lower Business Stream of priority, therefore, this method can reduce the transmitting power of the low AT of priority, thereby guarantees that the high AT of priority has higher transmitting power, guarantees the service quality of the AT that priority is high.
When the method in adopting step 1, step 2 and step 3 makes the detected ABIS reverse interface of BTS Congestion Level SPCC be no more than AbisStableThresh, at first need to recover the reverse MAC layer parameter setting of AT, then, cancel AT again and insert the restriction that message sends frequency, at last, recover the setting of RAB again.
BTS provided by the invention mainly comprises: memory module, detection module and congested control treatment module.
Memory module is mainly used in storage ABIS reverse interface pre-congested control thresholding, and what the pre-congested control thresholding of the ABIS reverse interface here can be in ABIS interface bandwidth occupancy thresholding, BTS traffic stream queues length threshold, the BTS Business Stream buffer performance thresholding is one or more.
Can also store the pre-congested control cancellation thresholding of ABIS reverse interface in the memory module, the pre-congested control cancellation thresholding of ABIS reverse interface should be less than the pre-congested control thresholding of ABIS reverse interface.The pre-congested control cancellation thresholding of ABIS reverse interface also can comprise multiple, corresponding with the pre-congested control thresholding of above-mentioned various ABIS reverse interfaces respectively.
Detection module should detect the pre-congested degree of ABIS reverse interface according to the thresholding of storing in the memory module, as detecting ABIS interface bandwidth occupancy, BTS traffic stream queues length, BTS Business Stream buffer performance etc.Description in concrete detection method such as the above-mentioned method.
