Description
Technical field
The present invention relates to technical field of digital mobile communication, relate generally to a kind of measurement result filter method, device and terminal.
Background technology
In cell mobile communication systems, cell reselection and switching are and important function.In order to realize cell reselection smoothly, terminal (UE) needs to measure the signal quality of different districts, so that it is resident to select suitable community to carry out.When UE is after certain community and network connect, UE still needs to measure the signal quality of its neighbor cell, to select suitable community to switch, meets mobility requirement.
Under connected state, the detailed process measured is: network side is by Survey control message (i.e. RRC (RadioResourceControl, radio resource control) reallocation message) send to UE, wherein, this Survey control message comprises other association attributeses measured mark, measuring object, report configuration and measure.UE goes to perform measurement according to the measuring object in Survey control message, report configuration, and reports network side according to measurement result generation measurement report.
Measure mark as the whole index measuring configuration, contain two son marks, measuring object mark and report configuration identifier, every height mark contains again respective association attributes, as measuring object mark contains measuring object attribute (as carrier frequency, Neighboring Cell List etc.), report configuration mark contains report configuration attribute (as event triggers or periodic report, the event definition (A1, A2...) triggered, triggered time (TimeToTrigger, TTT), number of times etc. is reported).
Other and measuring object is also had to configure irrelevant configuration with reporting in measuring control information, as RSRP (ReferenceSignalReceivedPower, unit is dBm) and the filterable agent k of RSRQ (ReferenceSignalReceivedQuality, unit is dB).This filterable agent configures separately for each wireless access technology.
To the measurement of measuring object (finally all corresponding to community), different systems adopts different method of measurement, is set by network side, is called measuring amount (measurementquantity), is used for reflecting the signal quality of community.Such as in LTE, that UE measures is RSRP or RSRQ.
For the measurement task that event triggers, after the measurement result (result after layer three filtration) of measuring object is assessed, meet the entry criteria (such as neighboring cell signal quality is better than thresholding) of event, and be just considered to the measuring object meeting trigger conditions when the duration is equal to or greater than TTT.After having measuring object to meet the trigger condition of event, reporting measurement reports, to network side, reports the measuring object in report to be sort according to the measuring amount of network settings, optimum above.
The above-mentioned measurement result carrying out measuring assessment carries out, after layer three filtration, namely filtering according to following formula to the measurement result of physical layer:
F
n=(1-a) F
n-1+ aM
nformula 1
Wherein, F
nthe up-to-date measurement result carrying out measuring assessment through layer three filtration, M
nthe up-to-date measurement result of physical layer, F
n-1that last (namely (n-1) is secondary) filters the measurement result carrying out measuring assessment, filtration parameter through layer three
k is filterable agent, represent historical measurement (i.e. (n-1) secondary measurement result of filtering through layer three, should namely in (n-1) secondary measurement result of filtering through layer three but also contain (n-2) secondary measurement result through layer three filtration) account for the ratio of most recent measurements, k is less, illustrates that the ratio that historical measurement accounts for is less.In addition, unless stated otherwise, filtration mentioned in this article is all specified is the filtration of layer three.
Current protocol also specify three kinds of mobile statuss of UE, normal, middling speed and at a high speed.In actual applications, find middling speed and UE at a high speed, the speed of reporting measurement reports can slow down, and the switching when cell edge also can postpone, and can cause call drop time serious.

cRmaxin time range, terminal carries out the number of times of cell reselection more than N
cR-Mbut not more than N
cR-H, then think and enter middling speed state, at T
cRmaxin time range, terminal carries out the number of times of cell reselection more than N
cR-H, then think and enter fast state, if at T
cRmaxHystin time range, terminal does not meet the condition entering high speed and middling speed state, then can recover normal condition.When terminal is in connected state, above-mentioned statistic processes is applicable equally, and just statistics is the number of times switched.
