Description
Technical field
The present invention relates to code division multiple access (CDMA) communication system handoff technique field, particularly a kind of method of checking compressed mode pattern sequence validity.
Background technology
Under cdma system frequency division multiplexing (FDD) pattern,, need subscriber equipment (UE) that the Target cell that switches is measured in order to carry out alien frequencies direct-cut operation, FDD to the preparation of switching between time-division multiplexing (TDD) switching and system.The frequency of these measurements is general different with the frequency of current UE work, needs to carry out different-frequency measure or isosystem measurement.Because a cover transceiver can only be operated on one group of transmitting-receiving frequency simultaneously, if will measure the signal of other frequency, receiver need quit work and frequency is switched to target frequency measure.Therefore, need a kind of mechanism in descending radio frames, to produce certain idle time slot, Here it is compact model.Compact model as shown in Figure 1, the figure middle and upper part is divided into the radio frames that the space is arranged, the figure lower middle portion is amplified for the part that the radio frames in band space is carried out, this space be exactly by spreading factor reduce by half, the transmission data slots (GAP) of a period of time of formation such as technology such as sign indicating number punching etc., in this section GAP, any data are not transmitted to UE in the base station.UE can utilize GAP that its radio-frequency transmitter is transformed into the target frequency that needs supervision, and target frequency is measured.
After in radio frames, parameters such as the length of compact model GAP, repetition period being configured, generated concrete compressed mode pattern, started all compressed mode pattern of calling in a plurality of measuring processes simultaneously and formed a compressed mode pattern sequence.The configuration parameter of a compressed mode pattern as shown in Figure 2, the one-period of the compressed mode pattern of being lifted among Fig. 2 comprises transmission space pattern 1 (TGpattern1) and transmits two sections of space pattern 2 (TG pattern2).The length (TGPL2) of the length (TGPL1) of transmission space pattern 1 and transmission space pattern 2 has determined the Cycle Length of compressed mode pattern, and the transmission space begins the length (TGL1) in timeslot number (TGSN), transmission space 1, the length (TGL2) in transmission space 2, the position that transmission gapping interval (TGD) has determined GAP.Space 1 (GAP1) and space 2 (GAP2) are the length of GAP, and scope is 0～14slot (time slot), are distributed in 1 frame or 2 frames.In addition, transmission space control frame timeslot number (TGCFN) has determined in the compressed mode pattern sequence to start the moment of article one compressed mode pattern, and compression space active time displacement (DeltaCFN) is the back compressed mode pattern that starts in the compressed mode pattern time deviation with respect to last the compressed mode pattern that starts.
Because the measurement that needs when switching is a kind of incessantly, there are many compressed mode pattern in the compressed mode pattern sequence that starts, after starting the compressed mode pattern sequence, every compressed mode pattern is according to parameters such as the length of different separately start-up times, GAP and cycles, in the time of in the radio frames that is added to, may make to occur the situation that same frame is taken by the GAP of a plurality of compressed mode pattern in the radio frames, cause that promptly GAP is overlapping.
Whenever 3G (Third Generation) Moblie agreement (3GPP) is defined in that the GAP of compressed mode pattern can not be overlapping, otherwise owing to occurred the space that a plurality of compressed mode pattern produce in the same radio frames, conflict phenomenon occurs.Simultaneously, in order to guarantee the channel transmission quality during starting the compressed mode pattern sequence, 3GPP 25.133 has stipulated that allowing continuous maximum spaces number is two frames.
The situation that produces conflict when between two compact models of compressed mode pattern sequence can be referring to shown in Figure 3, each lattice is represented a frame among Fig. 3, the frame that has GAP to take among the figure is filled with black, does not have not Fill Color of frame that GAP takies, and the frame that has GAP to take conflict is filled with grey.Article one, radio frames is a compact model 1, and the cycle is 8 frames, and the 3rd frame of filling with black has GAP to take; The second radio frames is a compact model 2, and the cycle is 8 frames, and the 1st and the 3rd frame of filling with black has GAP to take; Article three, radio frames is for starting the result after compact model 1 and compact model 2 superpose simultaneously, and the 1st frame is filled with black, and expression has GAP to take, and the 3rd frame is filled with grey, and expression has GAP to take conflict.This GAP takies conflict will be caused for can not realizing mistake between system's each several part of cooperating with compressed mode pattern, can not realize link in the physical layer of network side, and the UE side can not realize measuring also because of a plurality of measurement purposes are arranged simultaneously.
In the prior art, because constraints complexity, and the pattern length of checking is bad to be determined, can't be before startup the compressed mode pattern sequence be had or not GAP to take that conflict is checked and whether taken frame number by GAP continuously and surpassed the frame number quick check that maximum GAP continuously that the 3GPP agreement allows takies, influence operation real-time.Therefore, conventional method is to take pre-configured many pattern length very short, and the cycle becomes the compressed mode pattern of simple multiple relation, forms the one style combination of sets, when the pre-configured parameter in backstage, many compressed mode pattern in same group are disposed simultaneously at every turn.When needs start different-frequency measure or isosystem measurement, radio network controller (RNC) takes out from the pattern combination of sets measures required compressed mode pattern, form a compressed mode pattern sequence, and the configuration parameter of all compressed mode pattern in the compressed mode pattern sequence sent to base station node B and UE by signaling message, the compressed mode pattern sequence is not done inspection during this.
This mode does not consider that when parameter configuration DeltaCFN changes the influence to the conflict of compressed mode pattern sequence.Figure 4 shows that when compressed mode pattern 2 is 0 frame with respect to the DeltaCFN of compressed mode pattern 1, pre-configured compressed mode pattern does not have the situation of conflict, the frame that has GAP to take among the figure is filled with black, does not have not Fill Color of frame that GAP takies, and the frame that has GAP to take conflict is filled with grey.Article one, radio frames is a compact model 1, and the cycle is 8 frames, and the 3rd frame of filling with black has GAP to take; The second radio frames is a compact model 2, and the cycle is 8 frames, and the 1st frame of filling with black has GAP to take; DeltaCFN is 0 frame, after starting the compressed mode pattern sequence, compressed mode pattern sequence stack result is the 3rd radio frames, the the 1st and the 3rd frame of filling with black has GAP to take, but the frame that grey of no use is filled does not have GAP to take the situation of conflict, does not conflict between compact model 1 and the compact model 2, if but DeltaCFN is configured to 2 frames, then the compressed mode pattern sequence directly clashes.
Figure 5 shows that when compressed mode pattern 2 is 2 frames with respect to the DeltaCFN of compact model 1, the situation that the compressed mode pattern sequence clashes, the frame that has GAP to take among the figure is filled with black, does not have not Fill Color of frame that GAP takies, and the frame that has GAP to take conflict is filled with grey.Article one, radio frames is a compact model 1, and the cycle is 8 frames, and the 3rd frame of filling with black has GAP to take; The second radio frames is a compressed mode pattern 2, and the cycle is 8 frames, and the 1st frame of filling with black has GAP to take; DeltaCFN is 2 frames, and after the startup compressed mode pattern sequence, compressed mode pattern sequence stack result is the 3rd radio frames, and the 1st and the 3rd frame of filling with grey all exists GAP to take conflict.The compressed mode pattern sequence exists GAP to take conflict.
Because the compressed mode pattern sequential parameter can dispose, after the compact model that adopts compressed mode pattern to concentrate is formed the compressed mode pattern sequence, if during execute-in-place parameter is revised, the compressed mode pattern sequence after the parameter configuration is not fully checked in the prior art, the validity of parameter is not corresponding to be guaranteed, conflict between the compressed mode pattern in the compressed mode pattern sequence that just may cause starting can't be realized at that time.As having started isosystem measurement in the user's communication, after the compressed mode pattern sequence was carried out a period of time, GAP was overlapping, the compressed mode pattern sequence starts failure, cause Node B to return the radio link reconfiguration failure, flow process takes place interrupt, finally make different system handoff failure.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method of checking compressed mode pattern sequence validity, and this method can fully be checked the validity of compressed mode pattern sequence, improves the success rate that the compressed mode pattern sequence starts.
According to above-mentioned purpose, the invention provides a kind of method of checking compressed mode pattern sequence validity, the method includes the steps of:
A, determine the inspection length of compressed mode pattern sequence;
B, have tight GAP to take conflict inspection to the compressed mode pattern sequence in checking length, if there is GAP to take conflict, then the compressed mode pattern sequence is invalid; Otherwise, execution in step C;
C, in checking length, the compressed mode pattern sequence is carried out frame number that whether continuously GAP take and surpassed the maximum GAP continuously that allows and take the frame number inspection, take frame number if the frame number that continuous GAP takies has surpassed the maximum GAP continuously that allows, then the compressed mode pattern sequence is invalid; Otherwise the compressed mode pattern sequence is effective.
Wherein, definite method of checking length described in the steps A can adopt following steps:
The last item compressed mode pattern that starts in A1, the least common multiple that calculates all compressed mode pattern cycles in the compressed mode pattern sequence, the compressed mode pattern sequence is with respect to the active time displacement DeltaCFN of article one compressed mode pattern that starts, the surplus three's sum more than or equal to the maximum frame number that allows continuous GAP to take;
A2, determine the inspection length of compressed mode pattern sequence according to gained three sum in the steps A 1.
In the such scheme, can be according to the system real time requirement, preestablish the maximum length of checking, then described steps A 2 is: gained three sum in the steps A 1 and the maximum that requires to determine according to system real time are in advance checked that length compares, if three's sum is not more than the maximum length of checking, get three's sum as checking length,, get the maximum length of checking as checking length if three's sum is checked length greater than maximum.
In the such scheme, if system real time requires not to checking the strict restriction of length, steps A 2 is: the inspection length that gained three sum in the steps A 1 is defined as the compressed mode pattern sequence.
Step B is in this method: at first each compressed mode pattern in the compressed mode pattern sequence is marked the frame that is taken by GAP in checking length, check whether exist same frame to be repeated mark then, if exist same frame to be repeated mark, then the compressed mode pattern sequence has GAP to take conflict; If there is not frame to be repeated mark, then the compressed mode pattern sequence does not have GAP to take conflict.
Further, can use one-dimension array to represent that the GAP of compressed mode pattern sequence takies among the step B of this method, the following frame number that is designated as of array; At first the frame that is taken by GAP in the compressed mode pattern sequence is marked out,, the GAP of first compressed mode pattern is taken mark fill in into successively, till checking length then from 0 coordinate of array; Next compressed mode pattern is filled in the beginning that then returns array, if find the array member is arranged by twice mark in the process of filling in, illustrates that GAP is overlapping, and the compressed mode pattern sequence of current check has GAP to take conflict; Do not find the array member is arranged by twice mark if filled in compressed mode pattern all in the compressed mode pattern sequence, illustrate that not have GAP overlapping, the compressed mode pattern sequence of current check does not have GAP to take conflict.
Whether the step C of this method is: use sliding window check-up compressed mode pattern sequence to exist continuous GAP to take frame number and surpassed the maximum GAP continuously that allows and take frame number; After determining the size of sliding window, mobile sliding window, and check whether exist the frame number that is taken by GAP continuously to surpass the frame number that the continuous GAP of the maximum that allows takies in the sliding window.
Among the described step C of this method, can use one-dimension array to represent the compressed mode pattern sequence, the following frame number that is designated as of array, the length of array is the inspection length of compressed mode pattern sequence; From 0 coordinate of array, mark the frame that is taken by GAP in each compressed mode pattern in the array successively; Determine the minimum frame number of size for not allowing continuous GAP to take of sliding window; First array member from the one-dimension array of expression compressed mode pattern sequence begins to slide with sliding window, and whether surpassed the frame number that the continuous GAP of the maximum that allows takies by the position of continuous marking in the window in the inspection array, if exist in the array and surpassed the frame number that the continuous GAP of the maximum that allows takies by the position of continuous marking in the window, there is continuous GAP to take frame number in the radio frames of then checked compressed mode pattern sequence stack and surpasses the frame number that the continuous GAP of the maximum that allows takies; If the frame number that is taken above the continuous GAP of the maximum of permission by the position of continuous marking in the interior array of window does not exist after the stack of compressed mode pattern sequence continuously to be taken the frame number that frame number takies above the continuous GAP of the maximum of permission by GAP.
Further, among the described step C position that taken by GAP when marking, if there is GAP to take, is then represented with 1 in array,, then in array, represented with 0 if there is not GAP to take; When whether having been surpassed the frame number that the maximum GAP continuously that allows takies by the position of continuous marking in the array in the inspection, array member in the window is sued for peace, when if all summation gained results are not more than the frame number that the maximum GAP continuously of permission takies, in the radio frames of then checked compressed mode pattern sequence stack, GAP takies the frame number that frame number takies above the maximum GAP continuously that allows continuously; When the frame number that takies greater than the continuous GAP of the maximum that allows being arranged among the gained result, after superposeing, the compressed mode pattern sequence exists continuously to be taken the frame number that frame number takies above the continuous GAP of the maximum of permission by GAP if sue for peace.
The step C of this method can also be that when using the sliding window technology, the sliding window size is the minimum frame number that does not allow continuous GAP to take; Sliding window all compressed mode pattern from filled in the compressed mode pattern sequence do not have to find have the array member to be begun to move by first array member of the one-dimension array of the compressed mode pattern sequence of twice mark; When whether having been surpassed the frame number that the maximum GAP continuously that allows takies by the position of continuous marking in the array in the inspection, array member in the window is sued for peace, when if all summation gained results are not more than the frame number that the maximum GAP continuously of permission takies, in the radio frames of then checked compressed mode pattern sequence stack, taken frame number by GAP continuously and surpass the frame number that the continuous GAP of the maximum that allows takies; When the frame number that takies greater than the continuous GAP of the maximum that allows being arranged among the gained result, after superposeing, the compressed mode pattern sequence exists continuously to be taken the frame number that frame number takies above the continuous GAP of the maximum of permission by GAP if sue for peace.
In this method, the frame number that the frame number that the maximum GAP continuously of 3GPP agreement regulation can be taken takies as the maximum GAP continuously that allows.
Adopt method of the present invention, by whether the compressed mode pattern sequence there being GAP take conflict checking and whether have continuously and taken frame number by GAP and surpassed the maximum GAP that allows and take the frame number inspection, avoided starting invalid compressed mode pattern sequence and owing to start the flow process that invalid compressed mode pattern sequence causes and interrupt, improve the success rate that the compressed mode pattern sequence starts, guaranteed carrying out smoothly of isosystem measurement or different-frequency measure.The inspection length of the compressed mode pattern sequence that adopts in the method has not only satisfied the combination of traversal compressed mode pattern, also can not guarantee the communication quality of system owing to the control general spends the long real-time that influences system.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples, and with reference to accompanying drawing, the present invention is described in more detail.
Core concept of the present invention is: by determining the inspection length of compressed mode pattern sequence, and in checking length range, have or not GAP to take conflict to check and whether have GAP to take continuously to have surpassed the maximum GAP continuously that allows and take the frame number inspection to the compressed mode pattern sequence, avoided starting invalid compressed mode pattern sequence, improved the success rate that the compressed mode pattern sequence starts.
Lift a preferred embodiment of the present invention, the compressed mode pattern sequence of in checking length two compressed mode pattern being formed has or not GAP to take conflict to check, article two, after the compressed mode pattern stack, whether exist continuously to be taken frame number by GAP and surpass two frames and check.Two compressed mode pattern that present embodiment is lifted as shown in Figure 6, the frame that has GAP to take among the figure is filled with black, does not have not Fill Color of frame that GAP takies.Article one, radio frames is a compressed mode pattern 1, and the cycle is 8 frames, and the 1st frame of filling with black has GAP to take; The second radio frames is a compressed mode pattern 2, and the cycle is 8 frames, and the 1st frame, the 2nd frame and the 8th frame of filling with black have GAP to take; Article 2, pattern starts after the 1st pattern, and DeltaCFN1 is 3 frames.The step that this compressed mode pattern sequence validity is checked is as shown in Figure 7:
Step 701: the DeltaCFN of the compressed mode pattern that the compressed mode pattern that calculate the least common multiple M1 in all compressed mode pattern cycles in the compressed mode pattern sequence, starts at last starts with respect to article one, one are more than or equal to the surplus M2 three sum M of the maximum frame number that allows continuously to be taken by GAP.
In the present embodiment, have two compressed mode pattern in the compressed mode pattern sequence, the least common multiple that calculates two compressed mode pattern cycles is 8 frames; Article 2, the DeltaCFN of the compressed mode pattern that starts with respect to article one of the compressed mode pattern that just starts at last with respect to the DeltaCFN1 of the 1st compressed mode pattern of compressed mode pattern, promptly DeltaCFN is 3 frames; Surplus M2 more than or equal to the maximum frame number that allows continuously to be taken by GAP then be one more than or equal to 2 value, it is 2 that preferred mode is got surplus; Calculating above-mentioned three's sum M is 13 frames.
The present embodiment M that passes the imperial examinations at the provincial level is not more than and maximum checks that length describes, and actual inspection length is got 13 frames.
In the present embodiment, array length is 13, with the mark of compressed mode pattern 1 be filled up in the array for 1,0,0,0,0,0,0,0,1,0,0,0,0}; Compressed mode pattern 2 is 3 frames with respect to the DeltaCFN1 of compressed mode pattern 1, when being filled up to the mark of compressed mode pattern 2 in the array, does not fill in the front three of array, since the 4th mark of inserting compressed mode pattern 2 successively, filled in compressed mode pattern 1 and compressed mode pattern 2, the array of expression compressed mode pattern sequence is { 1,0,0,1,1,0,0,0,1,0,1,1,1} when filling in compressed mode pattern 2, does not find that the logarithm group membership repeats to compose 1 situation, there is not frame to be marked twice, therefore, in checking length, do not exist GAP to take conflict in the compressed mode pattern sequence of illustrated embodiment, carry out step 707.
Compressed mode pattern in present embodiment GAP in checking length takies situation as shown in Figure 8, the frame that has GAP to take among the figure is filled with black, there is not Fill Color of frame that GAP takies, GAP takies conflict, or continuous 3 frames and abovely taken by GAP, filling with grey, DeltaCFN is three frames, the maximum frame number that allows continuous GAP to take is two frames, checks that the radio frames in the length is 13 frames.Article one, radio frames is a compressed mode pattern 1, and the 1st frame and the 9th frame that identify with black have GAP to take; The second radio frames is a compressed mode pattern 2, and the 1st frame, the 2nd frame, the 8th frame, the 9th frame, the 10th frame that identify with black have GAP to take; Article three, radio frames is compressed mode pattern 1 and the result of compressed mode pattern 2 to check that length superposes, the 1st frame, the 4th frame, the 5th frame, the 9th frame with the black sign have GAP to take, continuous 3 frames of the 11st frame, the 12nd frame, the 13rd frame with the grey sign are taken by GAP, but it is overlapping not exist GAP to take, and does not have GAP to take conflict.
Step 707: judge whether that being taken frame number by GAP has continuously surpassed 2 frames.Use sliding window check-up compressed mode pattern whether to exist to be taken frame number by GAP continuously and surpassed 2 frames.Sliding window is taken as and does not allow the minimum frame number 3 that taken by GAP continuously, and sliding window is from 0 coordinate of the array of expression compressed mode pattern sequence.Three number group memberships in the window are worth addition, obtain first member's value of new array Y, to move one behind the window then, again the array member in the window is worth addition, obtain second member's value of array Y, and the like, if when in sliding window, the array member being worth addition, find that addition gained result equals 3, the maximum GAP continuously that then exists the frame that is taken by continuous GAP to surpass the permission of 3GPP agreement in the compressed mode pattern sequence takies frame number, then checked compressed mode pattern sequence is invalid, end check.If when array member in the sliding window is added in the array last, all do not equal 3 value among the new array Y of gained, then checked compressed mode pattern sequence is effective, withdraws from after finishing inspection.
In the present embodiment the radio frames of the compressed mode pattern of lifting 1 and compressed mode pattern 2 stack gained in checking length 13 frames, insert 0 with array representation, 1 the sign after as shown in Figure 9, the 1st frame, the 4th frame, the 5th frame, the 9th frame, the 11st to 13 frame are 1, and all the other positions are 0.Sliding window is at first from 0 coordinate of array, array member in the window is worth addition, first member's value that obtains new array Y is 1, be not equal to 3, be worth addition again with moving an array member in the rear hatch behind the window, second the member's value that obtains array Y is 1, also be not equal to 3, when being added to last bit array member, last the array member value that obtains Y is 3, illustrate that existing continuous GAP to take frame number after the compressed mode pattern sequence superposes has surpassed two frames, the compressed mode pattern sequence of this embodiment is invalid, finishes inspection and withdraws from.
Compressed mode pattern in present embodiment GAP in checking length takies situation that frame surpasses 2 frames continuously as shown in Figure 8, in the 3rd radio frames among Fig. 8 GAP not taking place and take conflict, but is taken by GAP with continuous 3 frames of the 11st frame, the 12nd frame, the 13rd frame of grey sign.
Above-mentionedly lift preferred embodiment, by determining the inspection length of compressed mode pattern sequence, have or not conflict to check and whether exist continuously to be taken frame number by GAP and surpassed the maximum GAP continuously that allows and take the frame number inspection, avoided starting invalid compressed mode pattern sequence to the compressed mode pattern sequence in checking length; Simultaneously, for satisfying the situation that the system transmissions quality is had higher requirements, can be according to concrete enforcement environment, determine the maximum length of checking, in maximum is checked length range, the compressed mode pattern sequence is checked, guarantee the transmission quality of system, improved the success rate that the compressed mode pattern sequence starts.
Abovely lift preferred embodiment, the purpose, technical solutions and advantages of the present invention are further described, institute is understood that, the above only is embodiments of the invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, be equal to replacement etc., all should be included within the scope of the present invention.
