Abstract
This invention discloses a flow control method for a time regulation frame, which sets a timer for each CCTrCH at the NodeB side, when a FP in CCTrCH appears out of the time window for the first time, the timer is started and the arriving time of ToA of said FP frame is recorded in the timer sphere and the successive frames are judged, when the timer exceeds the time, the ToA values in the timer sphere are processed evenly, then the difference between the back point of the time window and that mean value is taken as the time regulation value of said FP loading reported to RNC, when there are multiple loads in the CCTrCH, NodeB selects one of the latest time regulation value in all FP loads as the time regulation value of said CCTrCH reported to RNC, which can reduce the load of Iub interface because of over heavy flow of the time regulation frame to save resources.
Description
Technical field
The present invention relates to flow control technique, refer to a kind of method for controlling time regulating frame flow especially.
Background technology
In Wideband Code Division Multiple Access (WCDMA) (WCDMA) system, adopt the mode of Frame Protocol (FP) frame to carry out exchanges data between radio network controller (RNC) and the base station node B by Iub interface.At down direction, all corresponding certain delivery time of eating dishes without rice or wine of each FP frame, and be provided with this FP frame due in the latest in the NodeB side.RNC sent to NodeB in order to ensure the FP frame that issues before the due in the latest that NodeB requires, and can not shift to an earlier date too many because of the moment of FP frame arrival NodeB and the increase service delay again, had introduced the notion of time window and time regulating frame.
Time window is the time range that NodeB normally arrives NodeB regulation for the FP frame, this scope by time window before behind point (ToAWS) and the time window point (ToAWE) limit.Information in the time regulating frame is not arrive the time adjusted value that the transmitting time to follow-up FP frame that the FP frame of NodeB reports to RNC is adjusted in time window.
The absolute time that NodeB arrives according to the FP frame is calculated the ToA time of advent of this FP frame, the ToAWE that gets this FP frame according to the agreement regulation is the reference time point, then ToA is meant the time difference between the absolute time that ToAWE and FP frame arrive, following three kinds of situations are arranged: 1) ToA is less than zero, illustrate that the FP frame arrives after the point behind time window, promptly outside time window; 2) ToA greater than zero and its absolute value put before point and the time window after greater than time window poor, the arrival before the point before time window of FP frame be described, promptly outside time window; 3) ToA greater than zero and its absolute value put before point and the time window after less than time window poor, illustrate that the FP frame is within time window.If this ToA is not in the time window scope of RNC definition, then NodeB adjusts frame to the RNC transmitting time, promptly gives RNC the ToA value reporting, and RNC is according to the transmitting time of the follow-up FP frame of this parameter adjustment.From top three kinds of situations as can be seen, when ToA less than zero the time, the FP frame arrive absolute time apart from time window after point far away more, the ToA that claims this FP frame to arrive the absolute time correspondence is late more; And when ToA greater than zero and its absolute value put before point and the time window after greater than time window difference the time, the FP frame arrive absolute time apart from time window before point near more, it is late more to claim that this FP frame arrives the corresponding ToA of absolute time.
At present, to ToA be: go up any one FP frame not in time window as long as NodeB detects code combination transmission channel (CCTrCH) in the method for adjustment outside the time window, just report time regulating frame to RNC immediately, if promptly adjust if having time under the situation that frame reports, report time regulating frame one time to RNC at the Transmission Time Interval (TTI) of each FP frame.According to the time regulating frame that reports, RNC adjusts the delivery time of follow-up FP frame.Such as, the value of NodeB ToA in the time regulating frame that RNC sends is a positive number, then RNC postpones the delivery time of follow-up FP frame according to the value of this ToA.On the contrary, if the value of ToA is a negative, then RNC according to the value of this ToA with the delivery time of follow-up FP frame in advance.Here need explanation: RNC adjusts according to the time adjusted value that time regulating frame reports, but it is so big not necessarily just to adjust ToA, and is relevant with concrete RNC realization, adjusts in the time window as long as guarantee.
Usually, situation after easier generation FP frame appears at time window under the bigger situation of Iub interface data volume outside the point, at this moment, according to prior art, NodeB can frequently report time regulating frame to RNC, because adjusting frame this process itself, transmitting time also needs to take the bandwidth of Iub interface, thereby cause the aggravation of Iub interface tensity, it is more and more to cause appearing at behind the time window FP frame outside the point like this, and the number of times that reports of time regulating frame increases thereupon, forms inevitable vicious circle.
In addition, when certain user is in soft changing state, because RNC is distinguishing to the propagation delay time of different N odeB itself, arrive the base station A transmission time less than transmission time such as RNC to base station B, then might be when this user carry out soft handover, when the FP frame that sends from RNC arrives base station A, appear at before the time window before the point, and the FP frame is when arriving base station B, appears at behind the time window after the point.According to the prior art time adjusting method, base station A and base station B will report time regulating frame to RNC respectively, and obviously in this case, the time regulating frame that sends from base station A is nonsensical, be an invalid frame, also caused NodeB and RNC to handle the waste of resource and Iub port band width.And, if the time of carrying out, adjusted follow-up FP frame still failed to arrive NodeB in time window, NodeB again feedback time adjust frame to RNC during this period of time within the RNC time of carrying out adjust without any meaning, therefore during this period of time in the time regulating frame of NodeB transmission also be invalid frame.
In addition, because the unsteadiness of Iub interface transmission, may shake in the certain hour scope time of advent of the FP frame under the each detected same FP carrying of NodeB, if the time regulating frame that RNC reports according to NodeB is adjusted at every turn, situation inaccurate even the ToA vibration may appear adjusting.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method for controlling time regulating frame flow, and this method can effectively alleviate the Iub interface burden, saves the system handles resource, avoid vicious circle, can guarantee that RNC accurately adjusts the transmitting time of follow-up FP frame simultaneously.
For achieving the above object, technical scheme of the present invention specifically is achieved in that
A kind of method for controlling time regulating frame flow is provided with time window in the NodeB side, it is characterized in that, NodeB is provided with the timer that duration is Twait to CCTrCH, and this method may further comprise the steps:
A1. judge that according to the ToA time of advent of each FP frame current FP frame whether outside time window, if outside time window, writes down the ToA of current FP frame, and judges whether to start timer,, then enter next step if start; Otherwise, enter next step behind the startup timer; If within time window, return steps A 1;
B1. judge whether timer is overtime,, return steps A 1 if not overtime; Otherwise enter next step;
C1. computing time adjusted value, and the value that will obtain goes up the time adjusted value of Twait in the time as CCTrCH and reports RNC.
Step C1 described computing time of adjusted value is: the mean value that calculates all ToA values of noting in the Twait time.
In time, last all the FP frames of CCTrCH are carried in the same FP carrying at Twait.
In time, the FP frame on the CCTrCH is carried on respectively in a plurality of FP carryings at Twait,
Steps A 1 described judgement is in each FP carrying each FP frame of this FP carrying to be judged respectively;
Step C1 described computing time of adjusted value is that time adjusted value is separately calculated in each FP carrying earlier respectively, choose then institute if having time in the adjusted value the latest a value as the time adjusted value of this CCTrCH in Twait.
In time, the FP frame on the CCTrCH is carried on respectively in a plurality of FP carryings at Twait,
Steps A 1 described judgement is in each FP carrying each FP frame of this FP carrying to be judged respectively;
Step C1 described computing time of adjusted value is that time adjusted value is separately calculated in each FP carrying respectively;
Step C1 is described to be reported is that the free adjusted value of institute that will calculate reports RNC, and RNC chooses in the adjusted value that calls time on all the latest a value as the time adjusted value of this CCTrCH in Twait.
Describedly judge that whether current FP frame in the method outside the time window is: the absolute time that point and current FP frame arrive behind the computing time window poor, if this difference greater than zero and the absolute value of this difference put before point and the time window after greater than time window poor, perhaps this difference is less than zero, and then current FP frame is outside time window; Otherwise current FP frame is within time window.
Before the step C1, this method further comprises: the described ToA that notes is carried out the ALPHA Filtering Processing.
The method of described ALPHA Filtering Processing is: calculate respectively earlier that ToA current record under and ALPHA filter factor are to be amassed and the previous ToA that notes and deducts the product of the difference of ALPHA filter factor, calculate sum of the two then.
When only there being part FP to carry the time adjusted value reports and all report time adjusted value all greater than zero the time on the described CCTrCH, the NodeB adjusted value that on RNC, do not call time.
When described CCTrCH is a plurality of, step C1 RNC on each CCTrCH, choose respectively in the adjusted value that calls time on all the latest a value as the time adjusted value of this CCTrCH in Twait after, further comprise: RNC continues to choose in the time adjusted value of all CCTrCH the latest one as the time adjusted value in the Twait.
As seen from the above technical solution, the inventive method is that upward all FP carryings are provided with the timer that the first-class time for the treatment of is Twait to NodeB to CCTrCH, at certain FP carrying, detect in this FP carrying first not during the FP frame in time window at NodeB, note the ToA of this FP frame and start timer, be recorded in the stand-by period Twait in this FP carrying all not ToA values of the FP frame in time window then one by one, at last to this Twait in the time ToA value of all records average, deduct the difference of point value behind the time window reports RNC as this FP carrying time adjusted value with the mean value of this ToA afterwards.
At the situation that has a plurality of FP carrying all to need to call time adjusted value on certain CCTrCH, NodeB chooses time adjusted value that ToA carries and reports to RNC as the time adjusted value of this CCTrCH ToAWE after and apart from that the longest FP of ToAWE.If part FP carries detected ToA before time window before the point among the CCTrCH, and in addition part FP carrying does not detect the situation of ToA outside time window, then do not carry out any time and adjust frame and report to RNC.
This method sends a frame to the transmission frequency of time regulating frame by every TTI of prior art and is reduced to every Twait and sends a frame, obviously alleviated since time regulating frame frequently report the pressure that Iub interface causes; Simultaneously,, solved the RNC that the Iub interface instability causes preferably follow-up FP frame transmitting time adjusted inaccurate problem, increased the reliability of time regulating frame by ToA is carried out The disposal of gentle filter.In addition, the processing to a plurality of FP carryings has prevented to report the problem of invalid frame well, thereby has saved the system handles resource.

Embodiment
Core concept of the present invention is: each CCTrCH is provided with the timer that the first-class time for the treatment of is Twait, to the FP frame in certain FP carrying among the CCTrCH, when occurring the FP frame first outside the time window scope time, start timer, in the Twait time range, note all not ToA values of the FP frame in the time window scope; When timer expiry, after all ToA values of noting are averaged, this mean value is reported RNC as the time adjusted value of this FP carrying in the Twait time range.
To having only the situation of FP carrying on the CCTrCH, the time adjusted value of this FP carrying promptly is this CCTrCH to the time adjusted value that RNC reports.
To the situation of a plurality of FP carrying is arranged on the CCTrCH, NodeB select in the time adjusted value of all FP carryings of CCTrCH the latest one as this CCTrCH to time adjusted value that RNC reports.
Fig. 1 is the flow chart of the present invention to method for controlling time regulating frame flow, the present invention has two kinds of methods to the startup of timer, a kind of method is: start timer when detecting the outer FP frame of first time window, restart timing when detecting first FP frame time window outside after the timer expiry again; Another kind method is: just start timer after CCTrCH sets up, system carries out a time window adjustment at interval at each Twait automatically to be judged, and restarts timer at end Twait after the time interval.
Here, suppose NodeB for each CCTrCH is provided with the stand-by period timer, timing length is Twait, and timer adopts above-mentioned first kind of startup method.Concrete job step is as follows:
Step 100: in the NodeB side, when certain FP frame arrived, the base station judged that according to the ToA of this FP frame this FP frame whether outside time window, if outside time window, writes down this ToA value, enters next step; Otherwise, return step 100.
In this step, judge whether ToA can handle like this outside time window: three kinds of situations below having: 1) ToA illustrates that less than zero ToA is outside time window; 2) ToA greater than zero and its absolute value put before point and the time window after greater than time window poor, illustrate that ToA is outside time window; 3) ToA greater than zero and its absolute value put before point and the time window after less than time window poor, illustrate that ToA is within time window.
Step 101: judge whether timer starts,, then enter next step if start, otherwise, enter next step behind the startup timer.
Step 102: judge whether timer is overtime,, return step 100 if not overtime; Otherwise enter next step;
Step 103～step 104: calculate the mean value of all ToA values that Twait notes in the time, and get this mean value and report RNC as the time adjusted value of this CCTrCH in this Twait.
In this step, can only average processing to all ToA values of noting after, with this mean value as this Twait in the time on the adjusted value that calls time; Preferred methods is the method for all ToA values being carried out the ALPHA The disposal of gentle filter, and with last Y value as this Twait in the time on the adjusted value that calls time.The ALPHA The disposal of gentle filter is done like this:
The definition list entries is X (i), and output sequence is Y (i),
Y(0)＝X(0)；
Y(i)＝a*X(i)+(1-a)*Y(i-1)
Here, X (i) is the ToA value in the Twait time, and wherein X (0) is first ToA value in the Twait time; Y (i) is that X (i) is through value corresponding after the Filtering Processing.A is called the ALPHA filter factor in the formula, is the value of a value between (0,1), because each value of Y has all been considered the history value of input X, therefore can play level and smooth effect.Solved like this, preferably because the RNC that the ToA instability causes adjusts inaccurate problem.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing preferred embodiment that develops simultaneously, the present invention is described in more detail.
Suppose NodeB for each CCTrCH is provided with the stand-by period timer, timing length is Twait.
Embodiment one: have only the situation of a FP carrying on certain CCTrCH, promptly all the FP frames on the CCTrCH are carried in the same FP carrying.
Fig. 2 is the present invention has only a FP carrying on certain CCTrCH a time regulating frame flow control flow chart.Step 200 is just the same to the processing of step 104 to the processing method and the step 100 of step 204, and just the FP frame of this moment belongs in the FP carrying, and has only a FP carrying on CCTrCH.Be the time adjusted value of FP carrying among this CCTrCH to the time adjusted value that RNC reports in the step 204, because have only a FP carrying this moment on the CCTrCH, thus should the time adjusted value also be CCTrCH in Twait timer scope to time adjusted value that RNC reports.
From this embodiment as can be seen, the time interval that reports of time regulating frame is Twait, this method sends a frame to the transmission frequency of time regulating frame by every TTI of prior art and is reduced to every Twait and sends a frame, solved the pressure that causes to Iub interface because time regulating frame frequently reports well, to the The disposal of gentle filter of ToA value, solved preferably because the RNC that the ToA instability causes adjusts inaccurate problem.
Embodiment two: a kind of implementation that the situation of a plurality of FP carryings is arranged on certain CCTrCH.In the NodeB side, go up the time adjusted value that needs carry out the FP carrying of time adjustment according to CCTrCH, select a time adjusted value the latest to report RNC as this CCTrCH.
Fig. 3 is the present invention has a plurality of FP carryings on certain CCTrCH a time regulating frame flow control flow chart one, and the specific implementation step is as follows:
Step 300: calculate the time adjusted value that CCTrCH goes up each FP carrying according to the method for embodiment one.
The institute that step 301～step 302:NodeB is selected CCTrCH to go up to calculate is the latest a time adjusted value as this CCTrCH in the adjusted value if having time, and this value is reported RNC.
The processing of this step has following two kinds of situations:
When FP carries under the situation about being in outside the time window and after ToAWE, NodeB chooses the time adjusted value that absolute time that the FP frame arrives is carried ToAWE after and apart from that the longest FP of ToAWE, reports to RNC as the time adjusted value of this CCTrCH;
If part FP carried detected ToA before ToAWS among the CCTrCH, and in addition part FP carrying does not detect the situation of ToA outside time window, does not then carry out any time to RNC and adjusts frame and report.
Processing from this step, as can be seen this method except obviously having alleviated since time regulating frame frequently report pressure that Iub interface causes, and solved the RNC that the Iub interface instability causes preferably and adjusted outside the inaccurate problem, be in the processing of putting situation before before the time window in CCTrCH, having to be in outside the time window and only to have, prevent to report the problem of invalid frame well, thereby saved the system handles resource.
Embodiment three: the another kind of implementation that the situation of a plurality of FP carryings is arranged on certain CCTrCH.In the NodeB side, the time adjusted value that needs to carry out the FP carrying that the time adjusts on the CCTrCH is reported RNC, RNC chooses the institute that reports the latest a time adjusted value as this CCTrCH in the adjusted value if having time.
Fig. 4 is the present invention has a plurality of FP carryings on certain CCTrCH a time regulating frame flow control flowchart 2, and the specific implementation step is as follows:
Step 400: calculate the time adjusted value that CCTrCH goes up each FP carrying according to the method for embodiment one.
Step 401:NodeB reports RNC with the time adjusted value of all FP carryings.
Step 402:RNC chooses in the time adjusted value that this CCTrCH of reporting goes up all FP carryings a time adjusted value as this CCTrCH the latest, and the transmitting time of follow-up FP frame is adjusted accordingly.
The processing of this step still has following two kinds of situations:
When FP carries under the situation about being in outside the time window and after ToAWE, RNC chooses the time adjusted value that absolute time that the FP frame arrives is carried ToAWE after and apart from that the longest FP of ToAWE, as the time adjusted value of this CCTrCH;
If part FP carried detected ToA before ToAWS among the CCTrCH, and part FP carrying does not detect the situation of ToA outside time window in addition, and then RNC does not carry out any time adjustment.
From the method for present embodiment as can be seen, processing can reach effect of the present invention equally like this, is one of preferred embodiment of the present invention.
Especially, the Another Application of present embodiment is, when certain user is in soft handover, because NodeB can adjust a plurality of CCTrCH, this moment, RNC was at first with a time adjusted value as this CCTrCH of choosing respectively in the time adjusted value that each CCTrCH goes up all FP carryings the latest, and then of choosing in the time adjusted value of these CCTrCH the latest comes the transmitting time of follow-up FP frame is adjusted accordingly.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
