Description
Technical field
The present invention relates to the transmitting synchronous technology in the mobile communication system, relate in particular to a kind of Frame Protocol (FP) transmission channel method for determining asynchronous reason.
Background technology
In 3-G (Generation Three mobile communication system),, adopted the transport channel synchronization technology between radio network controller (RNC) and base station (NodeB) in order to guarantee to transmit the transmission of data between Iub interface and Uu interface.So-called transport channel synchronization is meant that RNC adjusts the delivery time of transport block set (TBS), makes the TBS of down link can arrive within the receive window of NodeB.The purpose of transport channel synchronization is to guarantee that the FP frame that RNC sends can be within the process range of NodeB, and can reduce the buffer memory of NodeB and handle load.When NodeB received the FP frame that comes from RNC outside process range, then NodeB must report the moment that receives Frame and the numerical value that process range departs from mutually, so that RNC adjusts the delivery time of FP frame, guarantees the Iub interface data synchronization.
Particularly, as shown in Figure 1, in the transport channel synchronization process, the pre-configured following parameter of system: the starting point time of advent (TOAWS), the end point time of advent (TOAWE), Base-Band Processing time T
Proc, the FP frame Connection Frame Number (CFN) and System Frame Number (SFN).Wherein, TOAWS and TOAWE are the starting point and the end point of NodeB receive window; CFN is the positive integer that is in 0 to 255 scope, returns 0 again after arriving 255; SFN is the current sequence number of FP frame in all frames of system, can be conversed the numerical value of SFN by CFN; T
ProcThe actual reception time of NodeB and the difference between the time of advent (LTOA) have the latest been shown.
When NodeB receives down link (DL) the FP frame that comes from RNC, the actual reception time of writing down this frame, and according to the SFN of CFN numerical computations correspondence entrained in this frame; Then pass through T
ProcSFN with obtaining determines LTOA.This moment, NodeB judged whether the time of reception of this FP frame lags behind LTOA, if then this FP frame is directly abandoned; Otherwise, judge according to time of reception whether this FP frame arrives NodeB in receive window.If within receive window, arrive, judge that then RNC and NodeB are in the transport channel synchronization state; Otherwise, judge that RNC and NodeB are in the asynchronous state of transmission channel.Taking place under nonsynchronous situation, NodeB compares the time of reception of this FP frame with TOAWE, obtain the numerical value of the time of advent (TOA), and the TOA that obtains is carried in up link (UL) synchronous control frame, send to RNC, so that RNC adjusts the sending order and the delivery time of follow-up FP frame according to this TOA.
By said process as seen, when the time of reception of FP is in outside the receive window, be in the nonsynchronous state of transmission channel between RNC and the NodeB.In the network operation process of reality, cause that the nonsynchronous reason of transmission channel mainly comprises: owing to transmitting time occur shake or drift cause RNC and NodeB to send the time instability of FP frame and actual TOA that NodeB reports incorrect.
In order to determine that causing the nonsynchronous reason of transmission channel, existing method is to utilize tester that the data between RNC and the NodeB are grasped, and carry out manual analysis.The deficiency that exists in the said method is:
1. utilize the manual mode of analyzing to determine the transmission channel asynchronous reason, depend on technical staff's professional standards largely, because the speed of manual process is slower, then can't reflect asynchronous reason timely simultaneously;
2. the nonsynchronous method of existing definite transmission channel only can be carried out in technical staff's operating time, and can't be carried out under unattended situation, and automaticity is lower, and the comfort level of use is relatively poor.

Embodiment
For making purpose of the present invention, technical scheme clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
The present invention is a kind of transmission channel method for determining asynchronous reason, its basic thought is: obtain the FP frame data that the asynchronous front and back of transmission channel take place, and accessed FP region frame data is divided into up FP frame and descending FP frame, then according to user's selection, utilize the time of reception and the CFN of up FP frame and descending FP frame, determine that respectively NodeB sends the time stability of FP frame and the time stability that RNC sends the FP frame; Perhaps, determine the correctness of the actual TOA of NodeB report according to the time of reception and the CFN of descending FP frame; Determine that perhaps NodeB and RNC send the time stability of FP frame and the correctness of the actual TOA that NodeB reports.
As embodiments of the invention, as shown in Figure 2, the system that finishes the transmission channel method for determining asynchronous reason comprises: interface, buffer cell, memory cell, processing unit and display unit.Wherein, interface is used to receive the FP frame data between RNC and the NodeB; Buffer cell is used for the real-time FP frame data of temporary transient storage under the control of processing unit, and sends the FP frame data of the asynchronous front and back of transmission channel to memory cell; Memory cell is used for the FP frame data that come from the asynchronous front and back of buffer cell are preserved, and analyzes and handles for processing unit; Processing unit is used to indicate buffer cell to carry out storage, and according to the FP frame data in the memory cell, determine that RNC and NodeB send the time stability of FP frame, determine the correctness of the actual TOA of NodeB report, thereby determine the nonsynchronous reason of transmission channel, and send above-mentioned result to display unit; The result that display unit is used for coming from processing unit shows.
Referring to Fig. 3, utilize said system, the transmission channel method for determining asynchronous reason may further comprise the steps in the present embodiment:
In the mobile communication system operation process of reality, when the current transmission channel synchronous regime of unattended operation or this mobile communication system of needs acquisition is also determined asynchronous reason, just to carry out real-time analysis.Therefore, the selection of making according to the tester in this step judges whether to carry out real-time analysis.For example: when the tester selects to be, then judge and to carry out real-time analysis; When the tester selects not, then judge and do not carry out real-time analysis.
The purpose of this step is: up FP data and the descending FP data between asynchronous front and back of transmission channel within a period of time, RNC and the NodeB take place in record, and with recorded data as the analysis foundation of determining the transmission channel asynchronous reason in the subsequent step.
As shown in Figure 4, be that half of buffer cell memory capacity is example with the storage number of asynchronous FP frame, the method for this step storage FP frame data comprises:
In this step, the interface in the system shown in Figure 1 under the control of processing unit, the up FP frame of intercepting RNC to the descending FP frame between the NodeB and NodeB to RNC.In addition, in order to guarantee the normal operation of system, system also will be in advance empties the data of all preservations in the memory cell.
It is asynchronous that step 3022～3023. judge whether transmission channel to occur according to the FP frame that receives, if then execution in step 3024; Otherwise, deposit the FP frame that receives in buffer cell, and return execution in step 3021.
This place judges whether to occur the nonsynchronous method of transmission channel according to the FP frame that receives: if having synchronous control frame in the FP frame that receives, judge that then transmission channel to occur asynchronous; Otherwise it is asynchronous that transmission channel does not appear in judgement.
Occurring under the nonsynchronous situation of transmission channel, processing unit is stored in the FP frame that receives in the buffer cell.Buffer cell herein can adopt first-in first-out (FIFO) memory to realize.In addition, in order to access enough FP frame data, also to set in advance the memory capacity of buffer cell.
Occurring under the nonsynchronous situation of transmission channel, processing unit at first deposits the FP frame that receives in buffer cell, then more whether the asynchronous FP frame of storage afterwards of generation transmission channel is reached required data volume and judges.FP frame after asynchronous reaches a half of buffer cell memory capacity, the FP frame data when 1/2nd in this buffer cell preserved transport channel synchronization, and other two/first what preserve is the FP frame data of transmission channel when asynchronous.Certainly, half of buffer cell memory capacity also can replace with other ratio according to the analysis needs of reality just for the front and back at asynchronous FP frame all can obtain enough data for analysis herein, for example 1/3rd, four/first-class.
Finished after the storage of asynchronous back FP frame, the processing unit notification interface no longer receives the FP frame between RNC and the NodeB, and processing unit notice buffer cell sends the FP frame of being stored to memory cell, so that can long preservation.
So far, finished the storage that the asynchronous front and back of transmission channel FP frame data take place.
In this step, under the situation of carrying out real-time analysis, when the FP of buffer cell frame data after memory cell is preserved, processing unit reads the FP frame data from memory cell, and tell up FP frame and descending FP frame according to the up-downgoing in each FP frame sign, so that use when determining the correctness of the stability of transmitting time and report TOA in the subsequent step.Do not carrying out under the situation of real-time analysis, original FP data in the memory cell are being analyzed differentiating uplink and downlink FP frame.
After the differentiation of having finished up-downgoing FP, carry out subsequent step according to tester's selection, promptly when tester's selection only during definite time stability, execution in step 304; When selecting only to determine the correctness of report TOA, execution in step 305; When selecting to determine the correctness of time stability and report TOA, while execution in step 304 and 305.
This step comprises two parts: determine that according to up FP frame NodeB sends the stability of the time of FP frame, and determine that according to descending FP frame RNC sends the stability of the time of FP frame.Since identical in this step to the processing method of up FP frame and descending FP frame, be that example describes therefore to determine that according to descending FP frame RNC sends the stability of the time of descending FP frame.
Influence the factor that RNC sends the time stability of descending FP frame and have two: whether a time that is RNC sends descending FP frame data exists shake, and whether another time that is RNC sends descending FP frame data exists drift.Wherein, determine whether the time that RNC sends descending FP frame data exist the basic thought of shake to be: the time of reception and the CFN that utilize every adjacent two FP frames in the descending FP frame queue, calculate actual reception time interval of every adjacent two descending FP frames and theoretical time of reception at interval, and determine at interval that according to the actual reception time interval of calculating and theoretical time of reception time jitter that RNC sends descending FP frame data whether.In addition, determine whether the time that RNC sends descending FP frame data exist the basic thought of drift to be: utilize the time descending FP frame the earliest and the time of reception and the CFN of time descending FP frame the latest in the memory cell, calculate actual multiframe time of reception at interval and theoretical multiframe time of reception at interval, and according to the actual multiframe time of reception that calculates at interval and the definite at interval RNC of theoretical multiframe time of reception send descending FP frame data time drift whether.
As shown in Figure 5, the method that definite RNC sends the time stability of FP frame in this step comprises:
The sequencing that step 30401. is pressed time of reception with the descending FP frame in the memory cell is arranged, and forms descending FP frame queue.
Because the descending FP frame in the memory cell might not be to store according to the sequencing of time of reception, so according to time of reception putting in order of each descending FP frame is adjusted in this step, form the FP frame queue.
Step 30402～30403. are time for reading two descending FP frames the earliest from descending FP frame queue, and with time frame early as the first descending FP frame, the frame that the time is later is as the second descending FP frame; From the first descending FP frame, obtain first time of reception and a CFN, and from the second descending FP frame, obtain second time of reception and the 2nd CFN.
Be the CFN of this frame setting in advance owing to all can carry the time of reception and the system of this frame in NodeB in each descending FP frame, therefore in two steps at this place, first, second time of reception and first, second CFN are extracted from first, second descending FP frame.
The actual reception time interval that step 30404. is calculated the first and second descending FP frames according to the time of reception that gets access to, and the theoretical time of reception interval of calculating two frames according to the CFN that gets access to.
Calculating the method in the actual reception time interval in this step is: calculate the difference between second time of reception and first time of reception.Theory of computation time of reception method at interval is: utilize the difference between the 2nd CFN and the CFN, be converted into theoretical time of reception at interval.Particularly, as a CFN during, the difference of the 2nd CFN and a CFN divided by the remainder after 256, be multiply by a pairing time of CFN again less than the 2nd CFN; As a CFN during, after the difference that the 2nd CFN is deducted a CFN adds 256, divided by 256 and get remainder, and then multiply by a CFN time corresponding more than or equal to the 2nd CFN.For example: first time of reception is that 200ms, second time of reception are that 280ms, a CFN are that the 150, the 2nd CFN is that 158, CFN time corresponding are 10ms, and then the actual reception time interval is in this step: 280-200=80ms; Theoretical time of reception is spaced apart: (158-150) mod256 * 10=8 * 10=80ms.For another example: first time of reception is that 20ms, second time of reception are that 2500ms, a CFN are that the 150, the 2nd CFN is that 142, CFN time corresponding are 10ms, and then the actual reception time interval is in this step: 2500-20=2480ms; Theoretical time of reception is spaced apart (142-150+256) mod256 * 10=2480ms.
Step 30405～30406. are according to the actual reception time interval that calculates and theoretical time of reception interval, judge whether the time that RNC sends descending FP frame exists shake, if, then write down the time of reception and the time jitter amount of the second descending FP frame, the transmission asynchronous reason is defined as the time instability that RNC sends descending FP frame data, and after carrying out alarm prompt, execution in step 30407; Otherwise, direct execution in step 30407.
In order to determine the shake of RNC transmitting time, present embodiment preestablishes descending shake precision, judge in the step 30405 then whether the time that RNC sends descending FP frame exist the method for shake to be: the actual reception time interval and theoretical time of reception are subtracted each other at interval, and with the difference that obtains as the downgoing time amount of jitter; If the absolute value of downgoing time amount of jitter, is then judged the time that RNC sends descending FP frame smaller or equal to descending shake precision and is shaken; Otherwise, judge that the time that RNC sends descending FP frame shakes.
Under the situation that shake occurs, the time of reception and the corresponding downgoing time amount of jitter of the second descending FP frame are noted, and will transmit asynchronous reason and be defined as the time instability that RNC sends descending FP frame data, it is unstable owing to there is shake then to point out that by alarm prompt RNC sends the time of descending FP frame, and shows the time of reception and the corresponding downgoing time amount of jitter of the second descending FP frame.
Step 30407～30408. judge whether the second descending FP frame is time descending FP frame the latest in the memory cell, if then execution in step 30409; Otherwise, time descending FP frame is early deleted from descending FP formation, return execution in step 30402.
The purpose that this place is judged is: determine whether there is not analyzed descending FP frame in the memory cell.When the second descending FP frame is not time during the latest descending FP frame, processing unit is deleted the time first descending FP frame early from descending FP frame queue.It may be noted that here and just time descending FP frame is early deleted from descending FP formation, and from memory cell, do not delete.In addition, after returning step 30402, the second descending FP frame before this is converted to the first descending FP frame, and next descending FP frame then becomes the 2nd FP frame.So repeat, finished the actual reception time interval between every adjacent two descending FP frames and theoretical time of reception interval in the descending FP formation.
Step 30409. according to the time in the memory cell the earliest and the time of reception of descending FP frame the latest calculate actual multiframe time of reception at interval, according to the time in the memory cell the earliest and the time of reception of descending FP frame the latest and CFN theory of computation multiframe time of reception at interval.
Because adjacent two frames are handled the jitter conditions that can only reflect the time, be difficult to the drift situation of reflection clock, then obtain the drift situation of clock in this step by the actual reception time interval between the calculating acquisition multiframe and the theoretical time interval.Particularly, the actual multiframe time of reception of this step computational methods at interval are: the time of reception of the time of reception of time descending FP frame the latest and time descending FP frame the earliest is poor in the calculating storaging unit.Theoretical multiframe time of reception computational methods at interval are: the difference of the time of reception of the CFN that utilizes time descending FP frame the earliest in the memory cell and the difference of the CFN of time descending FP frame the latest and time descending FP frame the earliest and the time of reception of time descending FP frame the latest is converted into theoretical multiframe time of reception interval.
Particularly,, at first the CFN of time descending FP frame is the latest deducted the CFN of time descending FP frame the earliest, obtain the parameter relevant with CFN as the CFN of time descending FP frame the earliest during less than the CFN of time descending FP frame the latest; And the real time at interval amassed the merchants that obtain and round divided by 256 and CFN time corresponding are at interval, the result after will rounding again multiply by 256, obtains the parameter relevant with time of reception; The parameter relevant with CFN that then will obtain adds the parameter relevant with time of reception, multiply by a pairing time of CFN again.As the CFN of time descending FP frame the earliest during greater than the CFN of time descending FP frame the latest, at first the CFN of time descending FP frame is the latest deducted the CFN of time descending FP frame the earliest, add 256 after, obtain the parameter relevant with CFN; And the real time at interval amassed the merchants that obtain and round divided by 256 and CFN time corresponding are at interval, the result after will rounding again multiply by 256, obtains the parameter relevant with time of reception; The parameter relevant with CFN that then will obtain adds the parameter relevant with time of reception, multiply by a pairing time of CFN again.
For example: the time of reception of time descending FP frame the earliest be 3: 15 afternoon the time of reception of 180ms, time descending FP frame the latest be that the CFN of 3: 20: 50 300ms, time descending FP frame the earliest is 2, the CFN of time descending FP frame the latest is that 198, CFN time corresponding are 10ms, then the actual reception time interval is in this step: 15 minutes 180ms=5 minute 50 seconds 120ms=350120ms during 3: 20: 50 300ms-3; Theoretical time of reception is spaced apart: ((198-2) mod256+Int (350120/2560) * 256) * 10=(196+34816) * 10=350120ms.
30410～30412. according to actual multiframe time of reception interval that calculates and theoretical multiframe time of reception interval, judge whether the time that RNC sends descending FP frame exists drift, if, then note the line time drift value, the transmission asynchronous reason is defined as the time instability that RNC sends descending FP frame data, and after carrying out alarm prompt, finish this stability and determine flow process; Otherwise, draw the rift-free result of time that RNC sends descending FP frame, and finish this stability and determine flow process.
In order to determine the drift of RNC transmitting time, present embodiment preestablishes descending drift accuracies, judge in the step 30410 then whether the time that RNC sends descending FP frame exist the method for drift to be: with actual multiframe time of reception at interval and theoretical multiframe time of reception subtract each other at interval, and with the difference that obtains as the downgoing time drift value; If the absolute value of time drift amount, is then judged the time that RNC sends descending FP frame smaller or equal to descending drift accuracies and is drifted about; Otherwise, judge that the time that RNC sends descending FP frame drifts about.
Under the situation that drift occurs, the downgoing time drift value is noted, and will transmit asynchronous reason and be defined as the time instability that RNC sends descending FP frame data, it is unstable owing to there is drift then to point out that by alarm prompt RNC sends the time of descending FP frame, and shows this time drift amount.
So far, finished and determined in the present embodiment that RNC sends the flow process of the time stability of descending FP frame.In addition, determining that NodeB sends in the method for time stability of up FP frame, what use is up FP frame in the memory cell, preestablish up shake precision and up drift accuracies, record also shows up amount of jitter and up drift value, and draw the conclusion that there is not drift in time that NodeB sends up FP frame when not having drift, others are all identical with method in the above-mentioned steps 30401 to 30412.
Because this step is whether the actual TOA that NodeB reports is correctly detected, therefore only need descending FP frame is handled.Particularly, as shown in Figure 6, this step determines that the method for TOA correctness comprises:
The sequencing that step 3051. is pressed time of reception with the descending FP frame in the memory cell is arranged, time for reading descending FP frame the earliest, and with the descending FP frame that read as current descending FP frame.
Because the descending FP frame in the memory cell might not be to store according to the sequencing of time of reception, so according to time of reception putting in order of each descending FP frame is adjusted in this step.
Step 3052～3054. obtain time of reception and CFN from current descending FP frame, and judge in the current descending FP frame whether comprise synchronous control frame, if then execution in step 3055; Otherwise, turn to next descending FP frame, return execution in step 3052.
This place judges in the current descending FP frame whether exist the purpose of synchronous control frame to be: determine RNC when sending current descending FP frame, it is asynchronous whether transmission channel to take place between RNC and the NodeB.
Step 3055. according to current descending FP frame and with the immediate DL synchronization FP of the time of reception of current descending FP frame frame in time of reception and CFN, calculate the permissible range of TOA.
Taking place under the nonsynchronous situation of transmission channel, obtaining the TOA numerical value of theory, so that determine the correctness of the actual TOA that NodeB reports in the subsequent step by the calculating of this step.In order to obtain the permissible range of TOA, at first calculate the central value of theory T OA in this step, the theory T OA central value by calculating then obtains the permissible range of TOA.The basic thought of the concrete computational methods of theory T OA central value is: utilize current descending FP frame time of reception and with the CFN of the poor and current descending FP frame of the time of reception of the immediate DL synchronization FP of the time of reception of current descending FP frame frame and poor with the CFN of the immediate DL synchronization FP of the time of reception of current descending FP frame frame, conversion theory T OA central value.Concrete grammar is:
Suppose to be respectively T1 and T2 with the time of reception immediate DL synchronization FP frame of current descending FP frame and the time of reception of current descending FP frame, be respectively CFN1 and CFN2 with the CFN of immediate synchronous FP frame of the time of reception of current descending FP frame and current descending FP frame, receive window length is TOAWms.As CFN1 during less than CFN2, the central value of theory T OA equals: the difference of T2 and T1 deducts the difference of CFN2 and CFN1 and get remainder after 256, the difference of adding T2 and T1 is long-pending divided by 256 and CFN time corresponding, multiply by 256 after rounding, and multiply by a CFN time corresponding again.As CFN1 during more than or equal to CFN2, the central value of theory T OA equals: after the difference of T2 and T1 adds 256, the difference that deducts CFN2 and CFN1 is got remainder again divided by 256, the difference that then adds T2 and T1 is long-pending divided by 256 and CFN time corresponding, multiply by 256 after rounding, multiply by a CFN time corresponding again.
The permissible range of TOA is: be lower limit with TOAW, add that with TOAW the TOA central value is the closed interval that the upper limit was constituted.
For example: CFN1=150, CFN2=162, T1=200ms, T2=280ms, receive window length is 30ms, a CFN time corresponding is 10ms, then theory T OA central value=(280-200)-((162-150)+Int ((280-200)/2560) * 256) * 10=-40ms; And the permissible range of TOA is :-40ms～-10ms.In other words, if actual TOA be in-40ms～-10ms, think all that then the actual TOA that NodeB reports is correct.
Step 3056～3057. judge whether the actual TOA of NodeB report is correct, if then execution in step 3058 according to TOA permissible range that calculates and the actual TOA in the synchronous control frame; Otherwise the actual TOA that the nonsynchronous reason of transmission channel is defined as the NodeB report is incorrect, and after carrying out alarm prompt, execution in step 3058.
This place judges whether correct method is for the actual TOA of NodeB report: the TOA permissible range that calculates in the step 3055 is compared with actual TOA in the synchronous control frame, if actual TOA is in the TOA permissible range, judge that then the actual TOA that NodeB reports is correct; Otherwise, judge the actual TOA mistake that NodeB reports.
Under the situation of the actual TOA mistake that NodeB reports, the actual TOA that the nonsynchronous reason of transmission channel is defined as the NodeB report is incorrect, and processing unit notifies display unit that the alarm prompt of actual TOA mistake is shown.
Step 3058. judges whether current descending FP frame is time descending FP frame the latest, if then finish the flow process that this determines the TOA correctness; Otherwise, return execution in step 3054.
This step judges whether current descending FP frame is that the time purpose of descending FP frame the latest is: determine whether there is not processed descending FP Frame in the memory cell.
So far, finished the flow process of determining the actual TOA correctness that NodeB reports in the present embodiment.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being made, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
