Illustrate herein, method provided in an embodiment of the present invention can be used for measuring the frequency in any network, especially Frequency suitable for the network including various bandwidth measures, such as can include traditional UMTS and Independent Carrier Wave S- UMTS network.Below by by taking the network including traditional UMTS and Independent Carrier Wave S-UMTS as an example, present invention below is described in detail The principle for the cell measuring method that embodiment provides.
Wherein it is possible to by the measurement between Independent Carrier Wave S-UMTS and traditional UMTS regard as between different-frequency measure, Or the isosystem measurement between can also the measurement between Independent Carrier Wave S-UMTS and traditional UMTS be regarded as.
It is that Independent Carrier Wave S-UMTS and traditional UMTS are regarded as belonging to same system, this is different in the scene of different-frequency measure Frequency measurement can be divided into：The different-frequency measure of same band, i.e., the measurement carried out between the different frequency of same band；With difference The different-frequency measure of bandwidth, i.e., the measurement carried out between the different frequency of different bandwidth.The different-frequency measure of same band includes：Tradition Measurement between the different frequency of same band under measurement under UMTS between different frequency, and Independent Carrier Wave S-UMTS. The different-frequency measure of different bandwidth includes：Measurement under traditional UMTS between the frequency of different bandwidth under Independent Carrier Wave S-UMTS, And the measurement under Independent Carrier Wave S-UMTS between the different frequency of different bandwidth.
It is to regard Independent Carrier Wave S-UMTS as different systems from traditional UMTS in the scene of isosystem measurement.Different system Unified test amount includes measurement Independent Carrier Wave S-UMTS to traditional UMTS lower frequencies, and traditional UMTS is under Independent Carrier Wave S-UMTS The measurement of frequency.In addition, other systems, such as LTE or GSM, are waited under Independent Carrier Wave S-UMTS and/or under traditional UMTS The measurement of frequency is also a kind of isosystem measurement scene, and method provided in an embodiment of the present invention is equally applicable.
In this example, it is assumed that when the frequency to different bandwidth measures, the measurement amount that network side is specified includes Ec/ No, the frequency of different bandwidth is compared from the angle of capacity, according to Shannon channel capacity formula C=W*log2 (1+S/N), Because the bandwidth W that Independent Carrier Wave S-UMTS is used is smaller than the bandwidth that traditional UMTS is used, in order to make up Independent Carrier Wave S-UMTS Difference between the bandwidth that the bandwidth and traditional UMTS used uses, UE can measure the judgement that reports of trigger event Before, quality evaluation value and/or decision threshold corresponding to each frequency are modified, to enable network side to be triggered according to measurement UE is switched to and can obtained in the frequency of more Large Copacity by reporting for event.
Below to support Independent Carrier Wave S-UMTS UE to wish to be switched to Independent Carrier Wave S-UMTS scene from traditional UMTS Exemplified by, method provided in an embodiment of the present invention is described further, but be not limited to the application scenarios.
Under above-mentioned scene, network side can issue different-frequency measure instruction to UE, and network is carried in different-frequency measure instruction Frequency under the Independent Carrier Wave S-UMTS of side instruction measurement, and measurement control message is sent to UE, the measurement control message is taken Measurement amount with network side instruction, it is assumed that the measurement amount includes Ec/No.After UE receives different-frequency measure instruction, therefrom obtain The frequency under the Independent Carrier Wave S-UMTS of network side instruction measurement is taken, it is described here to treat that measured frequency is included from different-frequency measure instruction Frequency under the currently used traditional UMTS of frequency and UE under the Independent Carrier Wave S-UMTS of acquisition；UE is from measurement control message Obtain the measurement amount；According to the measurement amount, each cell concentrated to the virtual active treated on measured frequency measures, According to measurement result, quality evaluation value corresponding to the virtual active collection on measured frequency is treated described in generation.In the present embodiment, with UE Illustrated exemplified by being modified to quality evaluation value, then UE is according to formula（1）Quality evaluation value is modified；Then will repair Quality evaluation value and decision threshold after just（Here decision threshold is unmodified decision threshold）It is compared, to determine Whether triggering measures reporting for trigger event.
It is that the virtual active of each frequency is concentrated so in relatively different frequency because UMTS does soft handover What the quality sum of all cells was compared.UE works as in the activation collection that the virtual active collection of currently used frequency is exactly UE, UE Preceding frequency of use is the frequency under traditional UMTS.If the revised quality evaluation value of the process of currently used frequency does not make Meet 2A, 2B, 2C, 2D or 2F judgment condition with the revised quality evaluation value of the process of frequency, then UE can be triggered accordingly Alien frequencies reported event.Here frequency is not used and refers to that network side indicates the frequency under the Independent Carrier Wave S-UMTS of measurement, i.e., it is described Treat measured frequency.
Wherein, when optimal frequency changes, 2A events are triggered；When the quality by amendment of currently used frequency is estimated Evaluation is less than certain thresholding, and when the quality evaluation value by amendment of a unused frequency be higher than certain thresholding, triggers 2B events；When the revised quality evaluation value of the process of a unused frequency is higher than certain thresholding, 2C events are triggered；When work as When the revised quality evaluation value of process of preceding frequency of use is less than certain thresholding, 2D events are triggered；When a unused frequency Process revised quality evaluation value when being less than certain thresholding, trigger 2E events；When currently used frequency is after amendment Quality evaluation value when being higher than certain thresholding, trigger 2F events.
For example, the judgement formula of 2A events can be following formula（4）.The judgement formula of 2C events can be following Formula（5）.
Q'NotBest≥Q'Best+H2a/2 （4）
Q'NonUsed≥TNonUsed2c+H2c/2 （5）
Wherein, formula（4）In, Q'NotBestBe it is described measurement trigger event report before non-optimal frequency through FIONotBest Revised quality evaluation value；Q'BestBe it is described measurement trigger event report before optimal frequency through FIOBestRevised matter Measure estimate；H2aIt is the lag parameter of the measurement trigger event.Formula（5）In, Q'NonUsedIt is to a unused frequency Through FIONonUsedRevised quality evaluation value, it has exceeded an absolute thresholding in the reporting events；TNonUsed2cIt is that this is different Frequency is used for the absolute thresholding that frequency is not used in measuring；H2cIt is the lag parameter of the measurement trigger event.FIONonUsedIt is described The unique biasing of frequency corresponding to frequency is not used.
In addition, UE can not be modified to the quality evaluation value of the frequency under Independent Carrier Wave S-UMTS, i.e., still use Quality estimation formulas originally, and the decision threshold to measuring trigger event is modified, specifically, UE can be under network side Plus the unique biasing of frequency on the basis of the absolute thresholding of hair.Wherein, UE needs the difference according to the bandwidth disposed in frequency, matches somebody with somebody Put the unique biasing of corresponding frequency.For example, by taking the 2A events under different-frequency measure as an example, then the judgement formula of 2A events can be public Formula（2）.In another example by taking the 2C events under different-frequency measure as an example, then the judgement formula of 2C events can be following formula（6）.
QNonUsed≥T'NonUsed2c+H2c/2 （6）
Formula（6）In, QNonUsedIt is the quality evaluation value to a unused frequency, the quality evaluation value is unmodified Quality estimation；T'NonUsed2cBe in the different-frequency measure be used for be not used frequency through FIONonUsedRevised decision threshold. , can be by FIO when that disposed in the frequency for needing to measure is traditional UMTSNonUsed0 is configured to, when in the frequency for needing to measure , can be by FIO when that dispose is the Independent Carrier Wave S-UMTS that contraction-expansion factor is 2NonUsedIt is configured to 3dB or 4dB.
In addition, network side in addition to sending different-frequency measure instruction to UE, can also send isosystem measurement instruction to UE, should Measurement process and different system are similar, will not be described in detail herein.
As fully visible, by the measurement of the frequency under the Independent Carrier Wave S-UMTS to different bandwidth, for different Bandwidth judges whether reporting measurement trigger event again after being modified to quality evaluation value or decision threshold so that network side is received After the measurement trigger event reported to UE, UE can be switched in the system frequency that the UE can be made to obtain more Large Copacity.
