Description
Technical field
The present invention relates to the radio network interface technology in the mobile communication system, relate in particular to a kind of method that activates compact model and determine transmission gap location parameter in the radio frames.
Background technology
At Wideband Code Division Multiple Access (WCDMA) (Wide Code Division Multiple Access, WCDMA) in the mobile communication system, other processing need be done in user terminal (UE) or base station (Node B) when sending radio frames under the specific occasion: for example to other alien frequencies networks, such as Frequency Division Duplexing (FDD) (FDD) net, time division duplex (TDD) net or Global Systems for Mobile communications (GSM) etc., it is monitored.Under this specific occasion, radio network controller (RNC) in the wireless access network (UTRAN) issues message that comprises compressed mode transmission gap pattern parameter and the compact model activation instruction that comprises activation parameter to Node B and UE, after Node B and UE receive activation instruction, activate the up-downgoing compact model according to the compact model activation instruction, perhaps only activate the upstream or downstream compact model, the radio frames in the wireless air interface is compressed according to compressed mode transmission gap pattern parameter.
Fig. 1 is the key diagram of compressed mode transmission gap pattern parameter, referring to Fig. 1, UE or Node B compress the radio frames of being launched according to compressed mode transmission gap pattern (TG pattern) parameter in the pattern parameter of compressed mode transmission gap, wherein the pane with shade is the continuous radio frames 101 after compressing, be spaced apart transmission gap (Transmission Gap between each radio frames, TG), transmission gap generally is made up of 2 to 7 continuous time slot, UE can utilize this transmission gap that the network of other frequencies is measured, in radio frames, the radio frames that comprises transmission gap is a condensed frame.In the radio network interface agreement, for example: in the standardized partnership projects of 3G (Third Generation) Moblie (3GPP) TS 25.215 agreements, two compressed mode transmission gap patterns 102 are set, and these two compressed mode transmission gap patterns 102 are incomplete same, but cycle alternation uses.The parameter that comprises in compressed mode transmission gap pattern 102 is as shown in table 1:
| Parameter name | English abbreviation | Unit |
| Transmission gap pattern serial number (ID) | TGPSID | -- |
| The initial time slot of transmission gap | TGSN | Time slot |
| Transmission gap length | TGL | Time slot |
| Transmission gap at interval | TGD | Time slot |
| Compressed mode transmission gap pattern length | TGPL | Frame |
Table 1
Above-mentioned parameter TGPSID, TGSN, TGL, TGD and TGPL are compressed mode transmission gap pattern parameter.
Activation parameter in the described compact model activation instruction is as shown in table 2:
| Parameter name | English abbreviation | Unit |
| Compact model activates frame number | CmChangeCfn | Frame |
| Transmission gap pattern ID | TGPSID | --- |
| The startup frame number of compressed mode transmission gap pattern | TGCFN | Frame |
| Transmission gap pattern number of repetition | TGPRC | Inferior |
Table 2
In the table 2, after CmChangeCfn represents that UE or Node B receive the compact model activation instruction, activate the frame number of compact model, only after this CmChangeCfn frame, could start the compressed mode transmission gap pattern of specifying TGPSID.TGCFN arrives after CmChangeCfn, when Connection Frame Number (CFN) equals this TGCFN frame, starts the transmission gap pattern of specifying TGPSID.If only activated a kind of compressed mode transmission gap pattern, then generally speaking, CmChangeCfn equates with the TGCFN that specifies TGPSID compressed mode transmission gap pattern; If activate multiple compact model, then generally speaking, CmChangeCfn equates with the TGCFN of the compressed mode transmission gap pattern that starts the earliest.When described TGPRC is 0, then the compressed mode transmission gap pattern of expression startup is that Infinite Cyclic is used, when TGPRC is non-0 value, the compressed mode transmission gap pattern that expression starts is limited recycling, the transmission gap pattern activate and used TGPRC number after promptly stop, this industry that stops at is called as compact model and stops naturally.
Above-mentioned compressed mode transmission gap pattern parameter value scope all is an integer.UE or Node B generally can activate four to six different compressed mode transmission gap patterns simultaneously according to self-ability, and different compressed mode transmission gap patterns are used for different measurement occasions.
Referring to Fig. 2, after Node B or UE receive the compact model activation instruction that comprises above-mentioned compressed mode transmission gap pattern parameter, when current frame number is CmChangeCfn, Node B or UE just can start compact model, when current frame number is TGCFN, start this TGCFN the compressed mode transmission gap pattern of corresponding TGPSID, again according to above-mentioned compressed mode transmission gap pattern compression of parameters radio frames.
In the channel of wireless communication system, identify each radio frames with CFN, the CFN value for recycle 0 to 255.May have repeatedly the variation of CFN from 255 to 0 in compact model, industry number is represented this change frequency with wheel usually, and a frame number of taking turns radio frames is 256.
Referring to Fig. 1, if compressed mode transmission gap pattern parameter is determined, then in each compressed mode transmission gap pattern, the relative position of transmission gap and this compressed mode transmission gap pattern start frame is fixed, and this transmission gap also relative fixed of the time slot position in the frame under it.
After activating compact model, to measure other alien frequencies networks at transmission gap, then must obtain the location parameter of each transmission gap earlier, the location parameter of described transmission gap comprises: the CFN frame number and the time slot position of transmission gap in this radio frames of radio frames under wheel number, the transmission gap under the transmission gap.The method of obtaining transmission gap location parameter in the radio frames in the prior art is all carried out following step in each radio frames:
A, calculating current wireless frame start the relative frame number of frame number with respect to all activated compressed mode transmission gap pattern, for example: the current wireless frame number is 240, it is 200 that compressed mode transmission gap pattern starts frame number TGCFN, wheel number is 2, then the frame number with respect to TGCFN is: 240+2*256-200=552, again with the obtain relative frame number of this value to the TGPL delivery;
B, calculating are in all activated compressed mode transmission gap pattern, and frame is with respect to the relative frame number of compressed mode transmission gap pattern under this transmission gap under the transmission gap;
C, judge whether the relative frame number of the compressed mode transmission gap pattern that present frame relative activates is the relative frame number of a condensed frame in this compressed mode transmission gap pattern, if, then there is transmission gap in present frame, obtains the time slot position of transmission gap according to compressed mode transmission gap pattern calculation of parameter; Otherwise, the transmission gap of the compressed mode transmission gap pattern that should not activate in the present frame.
But in above-mentioned prior art, every each radio frames of taking turns data all will judge whether to comprising transmission gap through above-mentioned processing, and the position of definite transmission gap, and resource consumption is big.
Because the prior art treating capacity is big, probability increase thus can further cause makeing mistakes, especially at soft handover, More Soft Handoff, between Node B under the situation of soft handover, need be with the compressed mode transmission gap pattern parameter of a plurality of Node B and consistent processing of compressed mode transmission gap pattern parameter of UE, RNC just need be dealt into different signalings each Node B, Node B handles respectively again, in the processing procedure of this complexity, and easier leading to errors.
In addition, reshuffling, under the signalings such as soft handover, though the normal RNC of generation was handed down to Node B with activation parameter and compressed mode transmission gap pattern parameter before CmChangeCfn arrives, but because the delay of transmission of messages arrives the situation that back Node B just receives activation parameter and compressed mode transmission gap pattern parameter at CmChangeCfn.If like this, then Node B just allows to activate compact model when the CFN of next round equals CmChangeCfn, therefore cause the moment of Node B and UE activation compact model inconsistent, the transmission gap location that both sides judge is also different, further cause the transmission gap position of UE and NODE B can not be synchronous, and may cause call drop or performance loss.
Summary of the invention
In view of this, main purpose of the present invention provides a kind of method that activates compact model and determine transmission gap location parameter in the radio frames, obtain the treatment step of transmission gap location parameter with simplification, reduce resource consumption, and can thoroughly eliminate the asynchronous of transmission gap position between Node B and the UE.

Node B or the UE of RNC in the wireless access network (UTRAN) in UTRAN issues message that comprises compressed mode transmission gap pattern parameter and the compact model activation instruction that comprises activation parameter.Wherein, compressed mode transmission gap pattern parameter is respectively: TGPSID, TGSN, TGL, TGD and TGPL; Activation parameter comprises CmChangeCfn, TGPSID, TGCFN and TGPRC.After Node B or UE receive activation instruction, when present frame arrives CmChangeCfn, start compact model, when certain concrete TGCFN value equals current C FN, then start the TGPSID compressed mode transmission gap pattern of this TGCFN correspondence.In the present invention, the frame of indication all is a radio frames.Node B or UE can start multiple compact model simultaneously.
After a concrete compact model is activated, the radio frames of launching in the air wireless interface is compressed segmentation, had certain transmission gap in the radio frames, the shared time slot of transmission gap can utilize this transmission gap that the network of other frequencies is measured for being compressed time slot.
In the present invention, the wheel compression mode transfer gap pattern length value in a kind of compact model is set to can be with 256 numbers of dividing exactly, for example, in the present embodiment, TGPL=TGPL1+TGPL2, it is worth desirable 1,2,4,8 ..., or 256, that is to say: TGPL=2
K, wherein K=0,1 ... or 8.
Referring to Fig. 3, the described method of obtaining transmission gap location parameter in the radio frames of this optimum embodiment also comprises:
Step 301, with the Active Frame CmChangeCfn of compact model as present frame, and with the counter O reset that sets in advance;
Step 302, obtain in all compressed mode transmission gap patterns, all transmission gaps are with respect to the relative position parameter of compressed mode transmission gap pattern under it, promptly obtain relative frame number CfnOffset and transmission gap it under the time slot position in frame of the affiliated frame of transmission gap with respect to compressed mode transmission gap pattern under it.Described time slot position mainly is to obtain the position GapSatrtSlot of the initial time slot of transmission gap in affiliated frame and the position GapEndSlot of termination time slot;
The method of obtaining transmission gap relative position parameter has multiple, and is existing known technology, and a kind of acquisition methods that adopts in the present embodiment is:
At first, obtain the initial time slot of transmission gap, for example, in the compressed mode transmission gap pattern 1 shown in Figure 1, the initial time slot of transmission gap 1 is TGSN, and the initial time slot of transmission gap 2 is TGSN+TGD.
Secondly, divided by 15, the integer part that obtains is the relative frame number of frame under this transmission gap with respect to compressed mode transmission gap pattern with the initial time slot of transmission gap, and remainder partly is the GapSatrtSlot of transmission gap.Two kinds of situations are arranged herein, if GapSatrtSlot and transmission gap length and less than 15, then GapEndSlot be GapSatrtSlot and transmission gap length and.If GapSatrtSlot and transmission gap length and greater than 15, then frame is two frames under the transmission gap, wherein the relative frame number of first frame is for the initial time slot of the transmission gap integer part divided by 15 values of obtaining, remainder partly is the GapSatrtSlot of first frame, and its GapEndSlot is last time slot 14 of first frame; The relative frame number of second frame is that GapSatrtSlot that the relative frame number of first frame adds one, the second frame is that the GapEndSlot of initial time slot 0, the second frame of this frame is that the GapSatrtSlot of first frame adds transmission gap length, deducts 15 values that obtain again.
Step 303, with the compressed mode transmission gap pattern of first activation compressed mode transmission gap pattern as current activation;
Step 304, obtain the relative frame number of present frame with respect to the compressed mode transmission gap pattern of current activation;
Present embodiment adopts obtains present frame and with respect to the concrete grammar of the relative frame number of the compressed mode transmission gap pattern of current activation is:
At first, obtain interval frame number Distance between the TGCFN of compressed mode transmission gap pattern of current frame number and current activation; Described Distance obtains by following formula (1): Distance=CurrentCfn+256 * CfnCircleNum-CmChangeCfn-TgcfnToCmchangecfn
Formula (1)
Wherein, CurrentCfn is current frame number, CfnCircleNum is for after activated compact model, the change frequency of the frame number of channel from 255 to 0, just above-mentioned wheel number, TgcfnToCmchangecfn are that the CmChangeCfn of compressed mode transmission gap pattern of current activation is to the interval of TGCFN.
If described Distance is a negative, illustrate that the compressed mode transmission gap pattern TGCFN when pre-treatment does not arrive, direct execution in step 309, otherwise, obtain the relative frame number CurrentCfnOffset of present frame with a wheel compression mode transfer gap pattern length T GPL in the pattern parameter of compressed mode transmission gap with respect to compressed mode transmission gap pattern according to the interval frame number Distance of above-mentioned acquisition; CurrentCfnOffset described herein is: the remainder that obtains divided by the TGPL of a compressed mode transmission gap pattern of taking turns with Distance.Owing in the wheel compression mode transfer gap pattern two compressed mode transmission gap patterns are arranged in the present embodiment, therefore, TGPL herein be TGPL1 and TGPL2 and, in this case, need judge that also whether CurrentCfnOffset is greater than TGPL1, if then present frame compresses in the pattern at second, and the relative frame number of present frame is CurrentCfnOffset-TGPL1; Otherwise present frame is in first compression pattern, and the relative frame number of present frame is CurrentCfnOffset.
Whether step 305, the relative frame number of judging present frame are the relative frame number of frame under the transmission gap in the same compressed mode transmission gap pattern that obtains of step 302, if, execution in step 308; Otherwise, execution in step 306.
Step 306, judge whether the compressed mode transmission gap pattern of in addition other activation, if having, then execution in step 307, otherwise, execution in step 309.
Step 307, compressed mode transmission gap pattern that the next one is activated are returned step 304 as the compressed mode transmission gap pattern of current activation.
Step 308, judgement present frame are condensed frame, promptly there is transmission gap in this frame, and the transmission gap relative position parameter that the relative frame number with present frame that obtained in the step 303 is corresponding is as the relative position parameter of present frame transmission gap, relative frame number in the present frame transmission gap relative position parameter is changed into the frame number of present frame, with of the location parameter output of amended location parameter as transmission gap in the present frame, and preserve the location parameter of this transmission gap, execution in step 309.
Step 309, with next frame as present frame.
Step 310, judge whether that all activated compression mode starting frame number TGCFN arrives, if then execution in step 311, otherwise, return step 304.
Step 311, described counter add one.
Step 312, judge whether the value of counter is 256, if then execution in step 313; Otherwise, return step 304;
Whether step 313, the absolute frame number of judging present frame are the frame number of frame under the transmission gap preserving of step 308, if then illustrate to have transmission gap in the present frame, execution in step 314; Otherwise, direct execution in step 315;
Step 314, read the transmission gap location parameter of being preserved corresponding with current frame number, i.e. this frame number and the transmission gap time slot position in this frame, and with the location parameter output of the transmission gap location parameter that reads, execution in step 315 as transmission gap in the present frame;
Step 315, with next frame as present frame, return step 313.
In addition, the present invention also has a kind of embodiment, the step of this embodiment is similar to the step of above-mentioned optimum embodiment, just in step 310, if all activated compression mode starting frame number TGCFN arrives, then return step 303, or in step 312, if judge that the value of counter is not 256, then also return step 303.Adopt this embodiment can cause all obtaining at each frame the relative position parameter of a transmission gap, with respect to above-mentioned optimum embodiment, therefore the calculating more complicated of this embodiment is not used generally speaking.
In method of the present invention, described compressed mode transmission gap pattern length is optimized, and the value that is about to the wheel compression mode transfer gap pattern length in a kind of compact model is set to can be with 256 integers of dividing exactly, for example, supposing has two compressed mode transmission gap patterns in the pattern of a kind of compressed mode transmission gap, the then value TGPL=TGPL1+TGPL2 of a wheel compression mode transfer gap pattern length, and value 1,2,4,8 ..., 256.Just: TGPL=TGPL1+TGPL2=2
K, K=0...8.
Because a wheel compression mode transfer gap pattern length can divide exactly 256, and in channel, frame number from 0 to 255 circulation change, again because in each compressed mode transmission gap pattern, therefore the position relative fixed of each transmission gap, takes turns in the frame number variation at each, when being frame number from 0 to 255 variation, the location parameter of each transmission gap is relatively-stationary.As TGPRC when being unlimited, adopt above-mentioned steps, as long as calculate the complete one transmission gap location parameter of taking turns, be the frame number and the time slot position of transmission gap in this frame of frame under the transmission gap, and preserve, afterwards every takes turns during frame number changes, the transmission gap location parameter that the transmission gap location parameter just can adopt this to take turns fully, repetitive cycling is used, and significantly reduces the amount of calculation of compact model like this.
Further specify the beneficial effect that is brought behind the pattern length optimization of compressed mode transmission gap with a concrete example below.Referring to Fig. 4, if, two compressed mode transmission gap patterns are set in a kind of compact model, and the length of a wheel compression mode transfer gap pattern is: TGPL1+TGPL2=128, the startup frame number TGCFN of first round compressed mode transmission gap pattern is 20, wherein, frame is the 1st frame of compressed mode transmission gap pattern under first transmission gap, suppose that transmission gap is positioned at the 0th to the 5th time slot of this frame, therefore, the location parameter of this transmission gap is: frame number is the 0th to the 5th time slot in 20 the frame.
According to above-mentioned hypothesis, the second wheel compression mode transfer gap pattern starts behind first round compressed mode transmission gap pattern immediately, starting frame number is 148, because the position relative fixed of transmission gap in the pattern of every wheel compression mode transfer gap, therefore the frame number of first transmission gap condensed frame is 148 in this compressed mode transmission gap pattern, again owing to the corresponding relative position of transmission gap in this condensed frame fixed, or the 0th to the 5th time slot, therefore, the location parameter of first transmission gap is in the second wheel compression mode transfer gap pattern: frame number is the 0th to the 5th time slot in 148 the frame.
Because a wheel compression mode transfer gap pattern length is: TGPL1+TGPL2=128, and a frame number from 0 to 255 of taking turns radio frames changes, the quantity of frame number is 256, it is the twice of a wheel compression mode transfer gap pattern length, therefore, the startup frame number of third round compressed mode transmission gap pattern still is 20.Relative, the location parameter of first transmission gap of this wheel compression pattern is: frame number is the 0th to the 5th time slot in 20 the radio frames.Hence one can see that: the location parameter of first transmission gap is identical with the location parameter of first transmission gap in the first round compressed mode transmission gap pattern in the pattern of third round compressed mode transmission gap.
The rest may be inferred, and the position of first transmission gap is identical with the position of first transmission gap in the second wheel compression mode transfer gap pattern in the pattern of four-wheel compressed mode transmission gap.And in the pattern of later every two-wheeled compressed mode transmission gap, the position of first transmission gap is all identical.In addition, similar to first transmission gap in the pattern of above-mentioned compressed mode transmission gap, the position of other transmission gaps in the pattern of compressed mode transmission gap is also identical in the pattern of the compressed mode transmission gap of every two-wheeled.
By above-mentioned example, as can be seen, after compressed mode transmission gap pattern length carried out optimizing, take turns in 256 radio frames at each, the location parameter of each transmission gap is relative fixed all, and promptly transmission gap always repeats in a same position of taking turns in 256 frames.Therefore, method of the present invention only need be calculated the location parameter that one behind all compression mode startings are taken turns each transmission gap in 256 frames, just can every wheel the afterwards reuse this location parameter in 256 frames, and needn't be at every location parameter that calculates transmission gap in 256 frames of taking turns, reduce amount of calculation greatly, reduced expending of resource.
In addition, at problem of current existence: reshuffling, under the signalings such as soft handover, because that the delay of transmission of messages causes activating the frame number numerical value of compact model is identical, but not the frame number in same the wheel, and further cause the transmission gap position of UE and NODE B can not be synchronous.Adopt method of the present invention, owing to take turns in 256 frames every, the position relative fixed of each transmission gap, in same the wheel, do not activate compact model even be not, as long as its numerical value that activates frame number is identical, one take turns 256 frames after, also error correcting can be come, make the transmission gap position synchronous of UE and NODE B.
In addition, because in the foregoing description, TGPRC is an infinitary value, and each is taken turns in 256 frames, the position relative fixed of each transmission gap, therefore, when obtaining the location parameter of transmission gap, only need obtain the frame number of the described frame of transmission gap, and transmission gap shared time slot position in this frame gets final product.
The foregoing description is that TGPRC is when being infinitary value, the concrete operations flow process of the method for the invention, if in the compact model that is started, the TGPRC that one or more compact model is arranged is a finite value, then at these compact model, in step 302, further obtain TGPRC and be wheel number and frame number under last transmission gap of compressed mode transmission gap pattern of finite value.For example: concrete acquisition methods can for, with the length of compressed mode transmission gap pattern addition successively TGPRC time, the value that obtains is divided by 256, merchant's integer part is for taking turns number, frame number is the frame number of this transmission gap of being preserved in the step 308.And, in execution in step 304, and in the step 313, further comprise:
Obtain the described number of wheel of present frame, and judge that whether wheel number under the present frame and frame number be that above-mentioned TGPRC is wheel number and the frame number under last transmission gap of compressed mode transmission gap pattern of finite value, if, this compact model of deexcitation then, at this moment, also can disappear with the corresponding transmission gap of this compact model, therefore to remove the transmission gap location parameter that described step 308 is preserved, to described counter O reset, and return step 302, recomputate the positional information of all transmission gaps in 256 frames; Otherwise, continue to carry out subsequent step.
In addition, if the TGPRC of all compact models is a finite value, then utilizes above-mentioned deexcitation compact model successively suddenly, and behind last compact model of deexcitation, stop flow process of the present invention simultaneously.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with the people of this technology in the disclosed technical scope of the present invention; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
