Abstract
The invention discloses an optimized measurement report reporting method, which can avoid reporting redundant measurement reports. The method comprises that UE reports a current measurement report only when a neighboring cell to be reported currently is different from a neighboring cell carried in the latest measurement report; or the method comprises that the user equipment (UE), when the neighboring cell to be reported currently is the same as the neighboring cell carried in the latest measurement report, reports the measurement report to a network, but the measurement report does not carry the measurement result of the neighboring cell.
Description
Technical field
The present invention relates to moving communicating field, be specifically related to a kind of measurement report reporting method of optimization.
Background technology
In mobile communication system, interference inhibition and the switching under the connected state between the sub-district all are extremely important functions, specifically, when subscriber equipment (UE) gradually in current service cell when the edge moves, the signal strength signal intensity of current area is descending, the signal strength signal intensity of neighbor cell is strengthening, when the signal quality of neighbor cell during near equaling but still less than the signal quality of current service cell, neighbor cell is all very serious to the interference of these neighbor cells to interference and the UE of UE, be that so-called UE has entered an interference region, for auxiliary network is realized Interference Control, UE need measure the signal quality of these neighbor cells, report network, realize presence of intercell interference control (ICIC, Inter-Cell InterferenceCoordination).If UE continues to move to neighbor cell from this interference region, finally enter neighbor cell, in order to keep the quality of terminal received signal, UE also needs the signal quality of neighbor cell is measured, give network the reporting signal strength of neighbor cell, by the network decision this terminal is switched to the stronger base station of signal that newly enters by original base station, satisfy the mobility requirement.
Under connected state, the measurement behavior of UE is subjected to network control, and network sends to UE measuring control messages, and UE carries out according to the configuration of measuring control messages and measures.Measure configuration and comprise measurement sign, measuring object, measurement report configuration etc., wherein, measure the corresponding measuring object of sign and a measurement report configuration for one, unique definite measurement; Measuring object can be one group of sub-district on (group) frequency or the frequency, and to the measurement of measuring object, the measuring amount that different systematic surveys is different all is signal qualitys of reflection sub-district.The measurement report configuration comprises that measuring reporting types (periodically reports and reporting events, wherein reporting events comprises that the single of Event triggered reports the periodicity with Event triggered to report), the adjacent area quantity (maxReportCells) that maximum reports, measurement report number of times (reportAmount), periodic report is (reportInterval at interval, be suitable for periodically reporting periodicity to report, i.e. the periodic report timer duration with Event triggered) etc.The measurement event of definition generally comprises the lag parameter Hys of the entry condition of incident, the certain threshold Thresh that leaves condition, incident, incident, the duration (Time To Trigger abbreviates TTT as) of the trigger condition of incident (trigger condition comprises entry condition and leaves condition) and the side-play amount Offset of incident etc. at present.
Satisfying the example that is measured as that the UE mobility requires under the connected state, the measurement of reporting events type, its concrete measuring process is: network will be measured control messages and send to UE, and UE carries out the measurement parameter initialization according to measuring unique definite each measurement of sign.At a certain measurement, UE obtains this and measures each measuring object attribute and measurement result separately in whole measuring objects; UE carries out the incident assessment according to initialized parameter or predetermined threshold to the measurement result of each measuring object, determines at the measuring object that satisfies the corresponding measurement event entry condition of this measurement more than or equal to TTT in the time; UE is saved in the measuring object (this moment, measuring object corresponded to the sub-district) that these satisfy the incident entry condition in this measurement sign corresponding district tabulation (cellsTriggeredList); From the cell list of this measurement sign, obtain maximum maxReportCells best cells generation measurement reports and measurement report is sent to network side to weak by strong by signal quality then.
In order to satisfy the mobility requirement of UE under the connected state, require UE adjacent sub-district to be measured and reported the measuring object that satisfies the incident entry condition, some measurement event have been defined at present to adjacent sub-district, for example, the A3 incident, the entry condition that defines this incident is the signal quality high specific side-play amount of the signal quality of adjacent sub-district than current service cell: (Mn+Ofn+Ocn)-(Ms+Ofs+Ocs)＞Offset+Hys, when satisfying entry condition, trigger measurement report; The condition of leaving accordingly is the signal quality low specific side-play amount of the signal quality of adjacent sub-district than current service cell: (Mn+Ofn+Ocn)-(Ms+Ofs+Ocs)＜and Offset-Hys.Wherein Mn is the measurement result of the signal of neighbor cell, Ofn is the frequency special parameter of neighbor cell place frequency, Ocn is the cell-specific parameters of neighbor cell, Hys is the lag parameter that prevents that ping-pong from setting, Ms is the measurement result of the signal of current service cell, Ofs is the frequency special parameter of current service cell place frequency, and Ocs is the cell-specific parameters of current service cell, and Offset is a predetermined offset.For satisfying the mobility requirement, this moment Offset be configured to usually on the occasion of, Offset+Hys is more than or equal to 0, to satisfy the definition of entry condition; Offset-Hys＜0 is to satisfy the definition of the condition of leaving.
For auxiliary network is realized presence of intercell interference control (ICIC), when UE moves to the edge in current service cell gradually, when entering the interference region of each neighbor cell, require UE that all are satisfied signal quality near equaling but still report network less than the neighbor cell of current service cell signal quality; Accordingly, if UE returns from the current service cell edge gradually, UE leaves the interference region of each neighbor cell one by one, require UE to satisfy still remaining that signal quality is approaching to be equaled but still report network less than the neighbor cell of current service cell signal quality, network based these measurement reports judge whether UE enters or left the interference region of each neighbor cell, realize Interference Control.For the measurement that realizes ICIC reports, at present the A3 incident has been done expansion, in the measurement report configuration of A3 incident, increased the indication (reportOnLeave) that the condition of leaving triggers measurement report, if reportOnLeave is configured to very (TRUE), represent that then this A3 incident is the measurement event that is exclusively used in ICIC, also to trigger measurement report (non-ICIC measures, and the condition of leaving that satisfies incident when measuring object does not trigger the measurement report of this incident) when leaving condition when satisfying; If reportOnLeave is configured to vacation (FALSE), represent that then this A3 incident is to be used for the common measurement event that mobility requires that satisfies.When the A3 incident is used for the ICIC measurement, its entry condition is defined as the neighbor cell signal quality near equaling but still less than the current service cell signal quality: (Mn+Ofn+Ocn)-(Ms+Ofs+Ocs)＞Offset+Hys, when satisfying entry condition, trigger measurement report; Accordingly, leave conditional definition and be the neighbor cell signal quality, also trigger measurement report when leaving condition when satisfying much smaller than current service cell signal quality (Mn+Ofn+Ocn)-(Ms+Ofs+Ocs)＜Offset-Hys.The definition of each parameter be used for that common to satisfy the A3 incident that mobility requires identical, the distinguishing Offset of being generally be configured to negative (such as-6dB ,-4dB ,-2dB), Offset+Hys＜0 is to satisfy the definition of entry condition; Offset-Hys＜0 is to satisfy the definition of the condition of leaving.
The measurement report of event type has two kinds to report form: a kind of is that the single of Event triggered reports; Another kind is that the periodicity of Event triggered reports.The single of Event triggered reports and is meant that network side has disposed the measurement of an event type for certain UE, reportAmount is configured to 1, UE carries out the incident assessment according to measuring configuration parameter to the measurement result of each measuring object, the neighbor cell that satisfies the incident entry condition is saved in this measurement sign corresponding district tabulation, by signal quality by from the tabulation of this measurement sign corresponding district, obtaining maximum maxReportCells sub-districts generation measurement reports and measurement report is sent to network to weak by force, and only report the one-shot measurement report, unless in follow-up measurement evaluation process, there is new neighbor cell (new neighbor cell is meant the sub-district that is not present in this measurement sign corresponding district tabulation) to satisfy the entry condition of this incident again, UE is saved in new neighbor cell in this measurement sign corresponding district tabulation, once more by signal quality by from the tabulation of this measurement sign corresponding district, obtaining maximum maxReportCells sub-districts and generate measurement reports and measurement report is sent to network to weak by force, report number of times still for once at this moment; Especially, measurement for ICIC, if in follow-up measurement evaluation process, there is the sub-district to satisfy the condition of leaving in this measurement sign corresponding district tabulation, UE deletes the sub-district of satisfying the condition of leaving from cell list, and then by signal quality by from cell list, obtaining maximum maxReportCells sub-districts and generate measurement reports and measurement report is sent to network to weak by force, and only report the one-shot measurement report (for the measurement of non-ICIC, there is the sub-district to satisfy the condition of leaving in the cell list, UE deletes the sub-district of satisfying the condition of leaving from cell list, but does not trigger measurement report).
The periodicity of Event triggered reports and is meant that network has disposed the measurement of an event type for certain UE, reportAmount＞1, UE carries out the incident assessment according to measuring configuration parameter to the measurement result of each measuring object, the neighbor cell that satisfies the incident entry condition is saved in this measurement sign corresponding district tabulation, by signal quality by from the tabulation of this measurement sign corresponding district, obtaining maximum maxReportCells sub-districts generation measurement reports and measurement report is sent to network to weak by force, start-up period reports timer, if do not have new sub-district to satisfy the incident entry condition in follow-up a period of time, every reportInterval time (periodic report timer expiry), UE by signal quality by from the tabulation of this measurement sign corresponding district, obtaining maximum maxReportCells sub-district to weak by force, the periodicity reporting measurement reports, report reportAmount time at most, behind each report cycle measurement report, report number of times to add 1, restart periodic report timer (when reporting reportAmount second periodicity measurement report, dwelling period reports timer) simultaneously.In the process of periodicity reporting measurement reports or after periodically reporting measurement reports finishes (reporting number of times to reach reportAmount time), if there is new neighbor cell to satisfy the entry condition of incident, UE is saved in new neighbor cell in this measurement sign corresponding district tabulation, by signal quality by from the tabulation of this measurement sign corresponding district, obtaining maximum maxReportCells sub-districts generation measurement reports and measurement report is sent to network to weak by force, handle reports number of times to reset to 0 simultaneously, and restarts counting.
At present the processing that reports the periodicity with Event triggered to report to the single of Event triggered is not perfect, has leak.For example, to the measurement of an event type, if behind certain measurement report, the sub-district number in the tabulation of this measurement sign corresponding district reached report thresholding (cell1, cell2 ... cell
m, m=maxReportCells).New neighbor cell is arranged (as cell again in the follow-up measurement assessment result
M+1, cell
M+2) satisfy the entry condition of incident, meanwhile there is not the sub-district to satisfy the condition of leaving in this measurement sign corresponding district tabulation, UE is saved in new neighbor cell in this measurements sign corresponding district tabulation, still owing to cell
M+1, cell
M+2Signal strength signal intensity than cell1, cell2 ... cell
mSignal strength signal intensity poor, and cell1, cell2 ... cell
mThe strong and weak ordering of signal does not change, and this moment, UE still can trigger measurement report, Neighboring Cell List that reports and last measurement report identical (cell1, cell2 ... cell
m), especially, there is new neighbor cell to satisfy entry condition at every turn and all can will reports number of times to reset to 0 for the periodic measurement report of Event triggered, will report the measurement report of bulk redundancy thus.For the intensive zone of user, these redundant measurement reports will be wasted a large amount of valuable Radio Resources, reduce the throughput of network.
Especially, measure for ICIC, the problems referred to above exist equally, though and cell
M+1, cell
M+2Satisfy entry condition and triggered measurement report, but cell in fact
M+1, cell
M+2Do not report network side, cause network to realize cell

Embodiment
This paper provides three kinds of technical schemes to solve problems of the prior art, and scheme 1 and scheme 2 can be optimized at the measurement report of all event types; Scheme 3 is that the measurement report of measuring at ICIC specially is optimized, and promptly measures for ICIC, promptly can adopt scheme 1 and scheme 2 to be optimized and also can adopt scheme 3 to be optimized.Three schemes all are applicable to the measurement report of event type.Described event type comprises common the satisfy incident of mobility requirement and the incident that auxiliary network is realized presence of intercell interference control IC IC.
Scheme 1:
The adjacent area of carrying in adjacent area that the current needs of only that report and the last measurement report is inequality, and UE just reports described current measurement report.
If when the adjacent area of carrying in the adjacent area that reports of current needs and the last measurement report was identical, described UE is reporting measurement reports not, and do not reset that to report number of times be 0.
Measurement for certain incident type, when the adjacent area that current needs report refers to that UE measurement assessment has new neighbor cell to satisfy the entry condition of this incident, maximum maxReportCells the adjacent areas that signal quality is best that UE selects from this measurement sign corresponding district tabulation.
Measurement for ICIC, the adjacent area that described current needs report is meant that UE measures the condition of leaving that has one or more sub-districts to satisfy the corresponding measurement event of this measurements sign in the tabulation of the current measurement sign of assessment corresponding district and when deleted, and UE identifies maximum maxReportCells the adjacent areas that signal quality is best that corresponding district is selected tabulating from this measurements.
Periodic measurement for Event triggered reports, and such scheme obviously can be avoided the measurement report of bulk redundancy; Single for Event triggered reports, isolated sees, when being arranged at every turn, new sub-district satisfies the entry condition of this incident, when if the sub-district that this sub-district of selecting and last this measurement report is identical, UE is reporting measurement reports not just, only saved measurement report 1 time, but because under a sub-district a lot of UE are arranged usually, take all factors into consideration a plurality of UE for a long time, each UE saves the one-shot measurement report, obviously integrate the measurement report of finally still having avoided bulk redundancy, saved interface-free resources, improved the throughput of network.
In addition, UE judges that UE can divide multiple batches of reporting measurement reports when the sub-district number in the tabulation of current measurement sign corresponding district met or exceeded maxReportCells, and all sub-districts in cell list report and finish.When dividing multiple batches of reporting measurement reports, UE only calculates once when calculating reports number of times.
Scheme 2:
When the adjacent area of carrying in the adjacent area that current needs report and the last measurement report was identical, described user equipment (UE) did not carry the measurement result of described adjacent area to the network reporting measurement reports in the described measurement report.
For example UE can increase by one and is used to represent this measurement report and the last identical field of measurement report in described measurement report.
After network side is received this measurement report that does not carry the nearby region measurement result, judge that this measurement report is identical with last measurement report.
Measurement for certain incident type, the adjacent area that current needs report refers to that described UE measures when assessing the entry condition that has new neighbor cell to satisfy the corresponding measurement event of current measurement sign maximum maxReportCells the adjacent areas that signal quality is best that UE selects from this measurement sign corresponding district tabulation.
If this sub-district of selecting of UE is identical with the sub-district that last this measurement reports, then UE sends and measures indication to network side, and indication nearby region measurement result is identical with the measurement result that last this measurement reports, and reports number of times not reset to 0.
Described this measurement report indication nearby region measurement result is identical with the measurement result that last this measurement reports, be meant in the measurement report not information such as reporting neighboring cell tabulation and neighboring area signal intensity, only indicate this nearby region measurement result and the nearby region measurement that this measurement of last time reports to come to the same thing.
Measurement for ICIC, the adjacent area that described current needs report is meant: described UE measures the condition of leaving that has one or more sub-districts to satisfy the corresponding measurement event of this measurements sign in this measurements sign corresponding district tabulation of assessment and when deleted, and UE identifies maximum maxReportCells the adjacent areas that signal quality is best that corresponding district is selected tabulating from this measurement.
In addition, UE judges that UE can divide multiple batches of reporting measurement reports when the sub-district number in the tabulation of current measurement sign corresponding district met or exceeded maxReportCells, and all sub-districts in cell list report and finish.When dividing multiple batches of reporting measurement reports, UE only calculates once when calculating reports number of times.
Scheme 3:
For the measurement of ICIC, the sub-district number in this measurement sign corresponding district tabulation meets or exceeds maxReportCells, and UE divides multiple batches of reporting measurement reports, and all sub-districts in cell list report and finish.
Report and divide the multiple batches of measurement report that reports when calculating reports number of times, only to count once in the process.
By the following examples and with reference to accompanying drawing, technical scheme of the present invention is described in further details.Fig. 1 is the network topology schematic diagram of LTE system, has the S1 interface between core net and the base station, has X2 interface between the adjacent base station.Among 5 embodiment, UE all is arranged in the sub-district under the base station 1, the current connection status that is in.
Embodiment one
Embodiment one is intended to illustrate the technological thought when the present invention program 1 is applied to non-ICIC and measures.
Base station 1 sends measures control messages to UE, and the measurement event that is disposed is the A4 incident, and TTT is configured to 100ms, the measurement report number of times is configured to 3 times, the periodic report arranged spaced is 120ms, and promptly the periodic report timer duration is configured to 120ms, and the adjacent area quantity that maximum reports is configured to 3.UE measures assessment according to measuring the control messages initiation parameter to measuring object, suppose 400ms after UE begins to measure assessment in the time, and the measurement assessment result is as follows:
100ms:cell1, cell2, cell3 satisfy the entry condition of A4 incident, 3 cell signal quality by by force to a little less than be followed successively by: cell1, cell2, cell3.
100ms is to 200ms:cell1, and cell2, cell3 do not satisfy the condition of leaving of A4 incident; Cell4 satisfies the entry condition of A4 incident during 200ms, 4 cell signal quality by by force to a little less than be followed successively by: cell1, cell2, cell3, cell4.
200ms is to 400ms:cell1, and cell2, cell3, cell4 do not satisfy the condition of leaving of A4 incident; Cell5 satisfies the entry condition of A4 incident during 300ms, the signal quality of 5 sub-districts by by force to a little less than be followed successively by: cell3, cell1, cell2, cell4, cell5.
Then according to the present invention program 1 technological thought, in this 400ms, UE reports 3 measurement reports to give base station 1 (accompanying drawing 2) altogether:
(during 100ms): UE assessment is for the first time determined equaling TTT cell1 in the time, and cell2, cell3 satisfy the entry condition of A4 incident, cell1, cell2, cell3 are saved in the cell list, (Neighboring Cell List is cell1 to reporting measurement reports, and cell2 cell3) gives base station 1; Report number of times to put 1, start-up period reports timer.
(220ms) for the second time: the periodic report timer expiry, (Neighboring Cell List is cell1 to the UE reporting measurement reports, and cell2 cell3) gives base station 1, reports number of times to add 1, restarts the periodic report timer.
(340ms) for the third time: the periodic report timer expiry, (Neighboring Cell List is cell3 to the UE reporting measurement reports, and cell1 cell2) gives base station 1, reports number of times to add 1, and dwelling period reports timer.
Technological thought according to the present invention program 1, though cell4 satisfies the entry condition of A4 incident during 200ms, UE is saved in cell4 in the cell list, but because UE (is cell1 by signal quality by the cell list to a weak Neighboring Cell List of selecting and a preceding measurement report (during 100ms) is identical by force from cell list, cell2, cell3), so reporting measurement reports not reports number of times also not reset to 0; During 300ms to the processing of cell5 too.
Embodiment two
Embodiment two is intended to illustrate the technological thought when the present invention program 1 is applied to the ICIC measurement.
Base station 1 sends measures control messages to UE, the measurement event that is disposed is the A3 incident, and reportOnLeave is configured to very, and TTT is configured to 100ms, the measurement report number of times is configured to (single that is Event triggered reports) 1 time, and the adjacent area quantity that maximum reports is configured to 3.UE measures assessment according to measuring the control messages initiation parameter to measuring object, suppose 400ms after UE begins to measure assessment in the time, and the measurement assessment result is as follows:
100ms:cell1, cell2, cell3 satisfy the entry condition of A3 incident, and 3 cell signal quality are by to weak ordering being by force: cell1, cell2, cell3.
100ms is to 200ms:cell1, and cell2, cell3 do not satisfy the condition of leaving of A3 incident; Cell4 satisfies the entry condition of A3 incident during 200ms, and 4 cell signal quality are by to weak ordering being by force: cell1, cell2, cell3, cell4.
200ms during to 400ms:300ms cell4 satisfy the condition of leaving of A3 incident; Cell1, cell2, cell3 do not satisfy the condition of leaving of A4 incident, and the signal quality of 3 sub-districts is by to weak ordering being by force: cell1, cell2, cell3.
Then according to the present invention program 1 technological thought, in this 400ms, UE reports 1 measurement report to give base station 1 altogether:
(during 100ms): UE assessment is for the first time determined equaling TTT cell1 in the time, and cell2, cell3 satisfy the entry condition of A3 incident, cell1, cell2, cell3 are saved in the cell list, (Neighboring Cell List is cell1 to reporting measurement reports, and cell2 cell3) gives base station 1; Report number of times to add 1.
Technological thought according to the present invention program 1, though cell4 satisfies the entry condition of A3 incident during 200ms, UE is saved in cell4 in the cell list, but owing to UE is identical by strong cell list to a weak Neighboring Cell List of selecting from cell list and a preceding measurement report (during 100ms) by signal quality (all is cell1, cell2, cell3), so reporting measurement reports not reports number of times also not reset to 0.Equally, though cell4 satisfies the condition of leaving of A3 incident during 300ms, UE deletes cell4 from cell list, but owing to UE is identical by strong cell list to a weak Neighboring Cell List of selecting from cell list and a preceding measurement report (during 100ms) by signal quality (all is cell1, cell2, cell3), so reporting measurement reports not.
Embodiment three
Embodiment three is intended to illustrate the technological thought when the present invention program 2 is applied to non-ICIC and measures.
Base station 1 sends measures control messages to UE, and the measurement event that is disposed is the A3 incident, and reportOnLeave is configured to vacation, and other measurement parameters configurations and UE are beginning to measure measurement assessment result in the 400ms of assessment back with embodiment one.
Then according to the present invention program 2 technological thought, in this 400ms, UE reports 3 measurement reports to give base station 1 (accompanying drawing 3) altogether:
(during 100ms): UE assessment is for the first time determined equaling TTT cell1 in the time, and cell2, cell3 satisfy the entry condition of A3 incident, cell1, cell2, cell3 are saved in the cell list, (Neighboring Cell List is cell1 to reporting measurement reports, and cell2 cell3) gives base station 1; Report number of times to add 1, start-up period reports timer.
(during 200ms): UE assessment for the second time determine equal TTT in the time cell4 satisfy the entry condition of A3 incident, cell4 is saved in the cell list, but because UE (is cell1 by signal quality by the cell list to a weak Neighboring Cell List of selecting and a preceding measurement report (during 100ms) is identical by force from cell list, cell2, cell3), the UE reporting measurement reports is given base station 1, but information such as reporting neighboring cell tabulation and neighboring area signal intensity not in the measurement report, only indicate this nearby region measurement result identical with last measurement report, specifically can in measurement report, increase adjacent area result that a field is used to represent that this measurement report need report with on coming to the same thing of reporting of measurement report once, in addition do not carry the measurement result of any adjacent area in the measurement report; Perhaps can report the measurement report of a sky, promptly do not carry any nearby region measurement result, do not increase the measurement report of any indication yet, after network side is received this measurement report, judge that the nearby region measurement result that this measurement report need report is identical with last measurement report.Report number of times to add 1, restart the periodic report timer.
(300ms) for the third time: similar with cell4, UE assessment determine equal TTT in the time cell5 satisfy the entry condition of A3 incident, cell5 is saved in the cell list, and the UE reporting measurement reports indicates this nearby region measurement result identical with last measurement report; Report number of times to add 1, dwelling period reports timer.
Embodiment four
Embodiment four is intended to illustrate the technological thought when the present invention program 2 is applied to the ICIC measurement.Measure control messages configuration and UE and beginning to measure measurement assessment result in the 400ms of assessment back with embodiment two, then according to the present invention program 2 technological thought, in this 400ms, UE reports 2 measurement reports to give base station 1 (accompanying drawing 4) altogether:
(during 100ms): UE assessment is for the first time determined equaling TTT cell1 in the time, and cell2, cell3 satisfy the entry condition of A3 incident, cell1, cell2, cell3 are saved in the cell list, (Neighboring Cell List is cell1 to reporting measurement reports, and cell2 cell3) gives base station 1; Report number of times to add 1.
(during 200ms): UE assessment is for the second time determined equaling TTT cell4 in the time, satisfy the entry condition of A3 incident, cell4 is saved in the cell list, but owing to UE is identical by strong cell list to a weak Neighboring Cell List of selecting from cell list and a preceding measurement report (during 100ms) by signal quality (all is cell1, cell2, cell3), the UE reporting measurement reports is given base station 1, but information such as reporting neighboring cell tabulation and neighboring area signal intensity not in the measurement report only indicates this nearby region measurement result identical with last measurement report.
Technological thought according to the present invention program 2, though cell4 satisfies the condition of leaving of A3 incident during 300ms, UE deletes cell4 from cell list, but owing to UE is identical by strong cell list to a weak Neighboring Cell List of selecting from cell list and a preceding measurement report (during 200ms) by signal quality (all is cell1, cell2, cell3), and cell4 does not report base station 1 in the measurement report of 200ms, so reporting measurement reports not.
