Among above-mentioned steps S101 and the step S102, in the UE side, UE is in mobile process, can constantly detect the signal quality of current service cell and abutting subdistrict, if the signal quality of current service cell or abutting subdistrict changes, UE is then to the RNC reporting measurement reports, and RNC need to process measurement report, guarantees mobile subscriber's service continuity by the switching of travelling carriage Serving cell.

Simultaneously, in the RNC side, according to current system running environment, can indicate UE to carry out corresponding predetermined action, set up, adjust upstream rate or change Serving cell etc. such as radio bearer.

To adjust upstream rate as example, RNC need to send the transmission channel reallocation message to UE, so that UE carries out speed adjustment action; After UE finished speed adjustment action, UE returned the transmission channel reprovision to RNC and finishes message.

RNC constantly receives the measurement report that UE reports, and carries out in the process of predetermined action at UE, and RNC may receive a plurality of measurement reports continuously.

In the present embodiment, if RNC receives the measurement report that UE reports in the process of carrying out predetermined action, then record the measurement result of each residential quarter in each measurement report, and measurement report is carried out buffer memory.

When the buffer memory measurement report, RNC can adopt the measurement result in the current measurement report to cover measurement result in the last measurement report.

Wherein, measurement report comprises measurement result and event result, and measurement result comprises the radio signal quality of the residential quarter that UE measures; Event result comprises which event condition which residential quarter satisfies.

Therefore, when the buffer memory measurement report, the radio signal quality that RNC uses the measurement result small area in the current measurement report covers the radio signal quality of measurement result small area in the last measurement report, therefore, after UE executed predetermined action, the measurement result in each measurement report of RNC buffer memory was up-to-date measurement result.

Step S103 when UE finishes when carrying out predetermined action, judges the validity of each measurement report according to the most recent measurements of residential quarter, and according to judged result each measurement report is carried out respective handling.

After the UE predetermined action was finished, RNC was according to the most recent measurements of each residential quarter, and whether the residential quarter that rejudges in the event result of each measurement report the inside continues to satisfy event condition.If satisfy, illustrate that this buffer memory measurement report is effective, RNC can carry out subsequent treatment to measurement report, if do not satisfy, illustrates that the measurement report of this buffer memory lost efficacy, and need to abandon.Thereby avoided RNC to the processing of the measurement report that lost efficacy and cause send wrong command messages to UE, affected user's impression or cause the problem of call drop.

As shown in Figure 4, judge the validity of each measurement report among the above-mentioned steps S103 according to the most recent measurements of residential quarter, and according to judged result the step that each measurement report carries out respective handling comprised:

Step S1031, the sequencing that reports according to measurement report, and successively the event condition of the institute of the event result in measurement report foundation is calculated according to the most recent measurements of residential quarter;

Step S1032 judges according to result of calculation whether the residential quarter in the event result satisfies event condition in the measurement report, if then enter step S1033; Otherwise, enter step S1034;

Step S1033, measurement report is effective, and measurement report is carried out subsequent treatment;

Step S1034, measurement report is invalid, abandons measurement report.

Above-mentioned measurement report comprises: buffer memory measurement report between buffer memory measurement report and/or system between frequently interior buffer memory measurement report, frequency.

Below in detail with to buffer memory measurement report in frequently, frequently between between buffer memory measurement report and system the example that is treated to of buffer memory measurement report the present embodiment scheme is elaborated:

Example one:

As shown in Figure 5, Fig. 5 is frequently interior buffer memory measurement report process chart.In this example, suppose that professional downlink bearing is at transmission channel HS-DSCH (High Speed Downlink Shared Channel, high-speed downlink shared channel) on, up being carried on the transmission channel DCH (Dedicated Channel, dedicated channel).Residential quarter Cell1 and Cell2 are arranged in the Active Set, and wherein Cell2 is Serving cell.Its handling process is as follows:

Step S301, owing to need to adjust upstream rate, RNC sends the transmission channel reallocation message to UE;

Step S302, because the movement of UE, Cell1 degradation, UE reporting measurement reports (Cell1 satisfies the 1B event condition);

Step S303, because UE is in the process of speed governing, so RNC records Cell1 in the measurement report, the signal quality measurement result of Cell2, and this measurement report of buffer memory;

Step S304, because the movement of UE, the Cell1 quality improves, UE reporting measurement reports (Cell1 satisfies the 1D event condition);

Step S305, because UE is in the process of speed governing, so RNC records Cell1 in the measurement report, the signal quality measurement result of Cell2, and this measurement report of buffer memory;

Step S306, the UE speed governing is finished, and replys the transmission channel reprovision to RNC and finishes message;

Step S307, the sequencing that RNC reports according to measurement report is processed first the 1B measurement report of buffer memory.The signal quality of current C ell1, Cell2 brought in the 1B event calculate, find that Cell1 no longer satisfies the 1B event, think that the 1B measurement report lost efficacy, so abandon the 1B report.

Wherein, the computing formula of 1B event is:

$10\·\mathrm{Log}{M}_{\mathrm{Old}}+{\mathrm{CIO}}_{\mathrm{Old}}\≤W\·10\·\mathrm{Log}\left(\underset{i=1}{\overset{N_A}{\mathrm{\Σ}}}{M}_i\right)+(1-W)\·10\·\mathrm{Log}{M}_{\mathrm{Best}}-(R_{1b}+H_{1b}/2)---\left(1\right)$

In the above-mentioned formula (1):

M _OldIt is the measurement result of carrying out the Active Set residential quarter of event 1B judgement;

CIO _OldIt is the cell individual offsets (cell individual offset) of carrying out the Active Set residential quarter of event 1B judgement;

M _iIt is the measurement result of Active Set residential quarter;

N _AIt is the number of cells in the current Active Set;

M _BestIt is the measurement result of strong residential quarter in the Active Set;

W is a parameter of RNC appointment, expression best cell shared weights in calculating;

R is reporting range;

H _1bIt is the sluggish parameter of event 1B.

Step S308, RNC processes the 1D measurement report of buffer memory.The signal quality of current Cell1, Cell2 brought in the 1D event formula calculate, find that Cell1 still satisfies the 1D event, think that the 1D measurement report is effective, continue to process.Serving cell need to be changed to Cell1.

Wherein, the computing formula of 1D event is:

10·LogM _NotBest≥10·LogM _Best+H _1d/2(2)

In the above-mentioned formula (2):

M _NotBestIt is the measurement result of Active Set residential quarter;

M _BestIt is the measurement result of strong residential quarter in the Active Set;

H _1dIt is the sluggish parameter of event 1D.

Step 309, RNC sends the physical channel reallocation message to UE, and Serving cell is changed to Cell1.

Embodiment two:

As shown in Figure 6, Fig. 6 is buffer memory measurement report process chart between frequency.In this example, suppose that service downloading is carried on the transmission channel HS-DSCH (High Speed Downlink Shared Channel) up being carried on the transmission channel DCH (Dedicated Channel).Working carrier frequency is F1, and residential quarter Cell1 is arranged in the Active Set, work at present carrier frequency poor quality.The different carrier frequency of inoperative is F2, and the frequency of residential quarter Cell2 is F2.Its processing procedure is as follows:

Step S401, owing to need to adjust upstream rate, RNC sends the transmission channel reallocation message to UE;

Step S402, because the movement of UE, different carrier frequency quality improves, UE reporting measurement reports (different carrier frequency satisfies the 2C event condition);

Step S403, because UE is in the process of speed governing, so RNC records the signal quality measurement result of different carrier cell Cell2 in the measurement report, and this measurement report of buffer memory;

Step S404, because the movement of UE, different carrier frequency degradation, UE reporting measurement reports (different carrier frequency satisfies the 2E event condition);

Step S405, because UE is in the process of speed governing, so RNC records the signal quality measurement result of different carrier cell Cell2 in the measurement report, and this measurement report of buffer memory;

Step S406, the UE speed governing is finished, and replys the transmission channel reprovision to RNC and finishes message;

Step S407, the sequencing that RNC reports according to measurement report is processed first the 2C measurement report of buffer memory.The signal quality of current C ell2 is brought in the carrier frequency quality estimation formula, calculated the quality of different carrier frequency F2.Carrier frequency quality estimation formula is as follows:

$Q_{\mathrm{frequencyj}}=10\·\mathrm{Log}{M}_{\mathrm{frequencyj}}=W_j\·10\·\mathrm{Log}\left(\underset{i=1}{\overset{N_{\mathrm{Aj}}}{\mathrm{\Σ}}}{M}_{\mathrm{ij}}\right)+(1-W_j)\·10\·\mathrm{Log}{M}_{\mathrm{Bestj}},---\left(3\right)$

If carrier frequency j is the carrier frequency that is using, so following virtual active collection is then made a comment or criticism at the Active Set that uses carrier frequency.

In the above-mentioned formula (3), Q _FrequencyjIt is the quality of evaluation (dB value) of the virtual active collection of carrier frequency j;

M _FrequencyjIt is the quality of evaluation (mW value) of the virtual active collection of carrier frequency j;

M _IjIt is the measurement result of the concentrated cell i of virtual active of carrier frequency j;

N _AjIt is the concentrated residential quarter number of virtual active of carrier frequency j;

M _BestjThe virtual active that is carrier frequency j is concentrated the measurement result of the residential quarter that best measurement result is arranged;

W _jBe a parameter of RNC appointment, be used for the measurement result of reflection best cell to the proportion degree that affects of measurement quality assessment.

The quality of evaluation of above-mentioned formula (3) being calculated gained is that different carrier frequency quality is brought 2C event formula into, finds that different carrier frequency F2 no longer satisfies the 2C event, thinks that the 2C measurement report lost efficacy, so abandon the 2C report.Wherein, the computing formula of 2C event is:

Q _Nonused≥T _Nonused2c+H _2c/2(4)

In the above-mentioned formula (4):

Q _{Non used}It is the signal quality of not using carrier frequency that signal quality is better than absolute thresholding;

T _{Non used2c}It is the absolute thresholding that in inter-frequency measurement, is applied to not use carrier frequency;

H _2cIt is the stagnant parameter of 2C event.

Step S408, RNC processes the 2E measurement report of buffer memory.The signal quality of Cell2 is brought in the carrier frequency quality estimation formula (3), calculated the quality of different carrier frequency F2.The different carrier frequency quality of calculating gained brought in the 2E event formula calculate, find that different carrier frequency still satisfies the 2E event, think that the 2E measurement report is effective, continue to process.Because working carrier frequency quality and different carrier frequency quality are all bad, so need to measure between opening system.Wherein, the computing formula of 2E event is as follows:

Q _Non?used≤T _Non?used?2e-H _2e/2(5)

In the above-mentioned formula (5):

Q _NonusedThe signal quality quality of evaluation of not using carrier frequency poorer than absolute thresholding;

T _{Non used 2e}It is the absolute thresholding of using in the judgement formula;

H _2eIt is the sluggish parameter of 2E event.

Step 409, RNC sends to UE and measures control message, measures between opening system.

Example three:

As shown in Figure 7, Fig. 7 is buffer memory measurement report process chart between system.In this example, suppose that service downloading is carried on the transmission channel HS-DSCH (High Speed Downlink Shared Channel) up being carried on the transmission channel DCH (Dedicated Channel).Working carrier frequency is F1, and residential quarter Cell1 is arranged in the Active Set, work at present carrier frequency poor quality.Cell2 is the GSM residential quarter.Its processing procedure is as follows:

Step S501, owing to will adjust upstream rate, RNC sends the transmission channel reallocation message to UE;

Step S502, because the movement of UE, the Cell2 quality improves, UE reporting measurement reports (Cell2 satisfies the 3A event condition);

Step S503, because UE is in the process of speed governing, so RNC records the signal quality measurement result of different system cell Cell2 in the measurement report, and this measurement report of buffer memory;

Step S504, because the movement of UE, the working carrier frequency quality improves, UE reporting measurement reports (working carrier frequency satisfies the 2F event condition);

Step S505, because UE is in the process of speed governing, so RNC records the signal quality measurement result of working carrier frequency residential quarter Cell1 in the measurement report, and this measurement report of buffer memory;

Step S506, the UE speed governing is finished, and replys the transmission channel reprovision to RNC and finishes message;

Step S507, the sequencing that RNC reports according to measurement report is processed first the 3A measurement report of buffer memory.The signal quality of current C ell1 is brought in UTRAN (UMTS Terrestrial Radio Access Network) the mass of system estimation equation, calculated the quality of UTRAN system.Wherein, the mass of system estimation equation is:

$Q_{\mathrm{UTRAN}}=10\·\mathrm{Log}{M}_{\mathrm{UTRAN}}=W\·10\·\mathrm{Log}\left(\underset{i=1}{\overset{N_a}{\mathrm{\Σ}}}{M}_i\right)+(1-W)\·10\·\mathrm{Log}{M}_{\mathrm{Best}},---\left(6\right)$

In the above-mentioned formula (6):

Q _UTRANIt is the signal quality (dB value) of the Active Set of the present UTRAN carrier frequency that is using;

M _UTRANThe signal quality (mW value) of the Active Set of the UTRAN carrier frequency that is using at present;

M _iIt is the measurement result of Active Set small area i;

N _AIt is the number of Active Set small area;

M _BestIt is the measurement result of best cell in the Active Set;

W is a parameter of RNC appointment, is used for the measurement result of reflection best cell to the proportion degree that affects of measurement quality assessment.

The UTRAN mass of system that calculates gained is brought in the 3A event formula, found that the UTRAN system no longer satisfies the 3A event, think that the 3A measurement report lost efficacy, so abandon the 3A report.Wherein, the computing formula of 3A event is as follows:

Q _Used≤T _Used-H _3a/2?AND?M _Other?RAT+CIO _OtherRAT≥T _Other?DAT+H _3a/2(7)

In the above-mentioned formula (7):

Q _UsedIt is the quality of evaluation of the UTRAN system carrier frequency that using;

T _UsedIt is the absolute thresholding for the triggering 3A event of working carrier frequency configuration;

M _{Other RAT}It is the measurement result of other system cell;

T _{Other RAT}It is the absolute thresholding that is applied to other system triggers 3A event;

CIO _{Other RAT}It is the cell individual offsets (cell individual offset) of other system cell;

H _3aIt is the sluggish parameter of 3A event.

Step S508, RNC processes the 2F measurement report of buffer memory.The signal quality of Cell1 is brought in the carrier frequency quality estimation formula (3) into the quality of evaluation work carrier frequency F1.With the work of calculating gained frequently quality bring in the 2F event formula and calculate, find that working carrier frequency still satisfies the 2F event, think that the 2F measurement report is effective, continue to process.Because the working carrier frequency quality improves, so need to measure between shutdown system.Wherein, 2F event computing formula is as follows:

Q _Used≥T _Used?2f+H _2f/2(8)

In the above-mentioned formula (8):

Q _UsedIt is the CF signal quality of evaluation of using;

T _{Used 2f}It is the absolute thresholding that the CF signal used triggers the 2F event;

H _2fIt is the sluggish parameter of 2F event.

Step 509, RNC sends to UE and measures control message, measures between shutdown system.

Whether present embodiment RNC effectively comes measurement report is carried out respective handling by the measurement report that checks buffer memory.Only at measurement report still effectively in the situation, RNC just can continue to process this measurement report.Avoided the processing of the measurement report that lost efficacy and cause send wrong command messages to UE, affected user's impression or cause the problem of call drop.

As shown in Figure 8, one embodiment of the invention proposes a kind of RNC that processes measurement report, comprising: receiver module 801, record buffer memory module 802 and judging treatmenting module 803, wherein:

Receiver module 801 is used for receiving the measurement report that UE reports;

Record buffer memory module 802 is used for when UE execution predetermined action, the measurement result of each residential quarter in the measurement report records, and measurement report carried out buffer memory;

Judging treatmenting module 803 is used for when UE finishes the execution predetermined action, judges the validity of each measurement report according to the most recent measurements of residential quarter, and according to judged result each measurement report is carried out respective handling.

UE is in mobile process, can constantly detect the signal quality of current service cell and abutting subdistrict, if the signal quality of current service cell or abutting subdistrict changes, UE is then to the RNC reporting measurement reports, RNC need to process measurement report, guarantees mobile subscriber's service continuity by the switching of travelling carriage Serving cell.

Simultaneously, in the RNC side, according to current system running environment, can indicate UE to carry out corresponding predetermined action, set up, adjust upstream rate or change Serving cell etc. such as radio bearer.

To adjust upstream rate as example, RNC need to send the transmission channel reallocation message to UE, so that UE carries out speed adjustment action; After UE finished speed adjustment action, UE returned the transmission channel reprovision to RNC and finishes message.

RNC constantly receives the measurement report that UE reports by receiver module 801, carries out in the process of predetermined action at UE, and RNC may receive a plurality of measurement reports continuously.

In the present embodiment, if the receiver module of RNC 801 is received the measurement report that UE reports in the process of carrying out predetermined action, then record the measurement result of each residential quarter in each measurement report by record buffer memory module 802, and measurement report is carried out buffer memory.

When the buffer memory measurement report, RNC can adopt the measurement result in the current measurement report to cover measurement result in the last measurement report.

Wherein, measurement report comprises measurement result and event result, and measurement result comprises the radio signal quality of the residential quarter that UE measures; Event result comprises which event condition which residential quarter satisfies.

Therefore, when the buffer memory measurement report, the radio signal quality that RNC uses the measurement result small area in the current measurement report covers the radio signal quality of measurement result small area in the last measurement report, therefore, after UE executed predetermined action, the measurement result in each measurement report of RNC buffer memory was up-to-date measurement result.

After the UE predetermined action was finished, the judging treatmenting module 803 of RNC was according to the most recent measurements of each residential quarter, and whether the residential quarter that rejudges in the event result of each measurement report the inside continues to satisfy event condition.If satisfy, illustrate that this buffer memory measurement report is effective, RNC can carry out subsequent treatment to measurement report, if do not satisfy, illustrates that the measurement report of this buffer memory lost efficacy, and need to abandon.Thereby avoided RNC to the processing of the measurement report that lost efficacy and cause send wrong command messages to UE, affected user's impression or cause the problem of call drop.

As shown in Figure 9, judging treatmenting module 803 comprises: computing unit 8031 and decision operation unit 8032, wherein:

Computing unit 8031 is used for the sequencing that reports according to measurement report, and successively the event condition of the institute of the event result in measurement report foundation is calculated according to the most recent measurements of residential quarter;

Decision operation unit 8032 is used for judging according to result of calculation whether the residential quarter of event result in the measurement report satisfies event condition, if satisfy, then measurement report is effective, and measurement report is carried out subsequent treatment; Otherwise measurement report is invalid, abandons measurement report.

Above-mentioned measurement report can be buffer memory measurement report between frequently interior buffer memory measurement report, frequency, or buffer memory measurement report between system.

If measurement report is frequently interior buffer memory measurement report, the execution result of decision operation unit 8032 may be to send the physical channel reallocation message to UE, carries out Serving cell and switches; If measurement report is buffer memory measurement report between frequency, the execution result of decision operation unit 8032 may be to send the control message of measuring between opening system to UE; If measurement report is buffer memory measurement report between system, the execution result of decision operation unit 8032 may be to send the control message of measuring between shutdown system to UE.According to actual scene, the subsequent processes when measurement report is effective has difference.
