Description
The cross reference of related application
The application require on May 22nd, 2012 submit the 61/650th, the priority of No. 135 U.S. Provisional Applications, its disclosure mode by reference all is incorporated into this.
Technical field
Embodiments of the present invention relate to wireless communication technology field, relate in particular to a kind of method, device and subscriber equipment of the measurement result for definite cell signal.
Background technology
In existing network, even terminal remains static down, due to a variety of causes such as air interface radio multipath fadings, terminal receives network signal also can be along with the time changes.Therefore, when carrying out cell measurement, each community is not measured value in the same time may some shake.In addition, if terminal under the nonstatic state, terminal can change apart from the position of each base station and distance, and be reflected to each cell measurement value that shows as that cell signal measures, also has the variation varied in size.But this amplitude of variation is generally limited, and be a time dependent process, do not wait as changed the 10-20db left and right in several seconds.
For the shake back and forth that prevents this air interface signals causes Ping-Pong gravity treatment or the switching of minizone and the up link open loop transmit power is impacted, terminal generally can be carried out the filtering processing to the measured value of single, the measured value after adopting after filtering is as the measurement result of community, carries out gravity treatment, switching, the assessment of the event such as resident and the calculating of path loss.The filtering of general measured value is processed as follows:
Rscp=(1-n) * Rscp_history+n*RscpNew (i+1) formula (1)
Wherein i represents the i time measurement in certain community, Rscp_history represents the historical filter value of preserving before the inferior measurement in community (i+1), RscpNew (i+1) represents the instantaneous value of the inferior measurement in community (i+1), Rscp represents after the inferior measurement in community (i+1) measurement result after processing after filtering, for the assessment of the events such as gravity treatment, switching.
In addition, n is filtering factor, and span is n>0 and n<=1.If n=1, meaning does not have filtering to process, and each measurement result is all got real-time measurement values.The value of n is can not be too large but can not be too little, because each cell measurement all periodically carries out.Too little meeting causes that to converge to actual signal too slow, can not play level and smooth effect again too greatly, specifically can get a rational empirical value according to actual conditions.
Then, new historical filter value: Rscp_history=Rscp more after (i+1) inferior measurement, with the filtering next time for this community.
The introducing of filtering has substantially solved signal jitter on the existing network and has changed some problems of bringing.But in some cases,, while such as the use measuring instrument, terminal being carried out to sensitivity test, the measured value after employing after filtering, as the measurement result of community, can have a strong impact on the sensitivity test result of terminal.Below provided and used measuring instrument terminal to be carried out to two kinds of test scenes of sensitivity test:
(1) open loop power control (OLPC) test: by the transmitting power by measuring instrument-25db and-108dB between switching back and forth, the up link open loop transmit power size of test terminal.
(2) go out service area (OOS) test: the measuring instrument Initial Trans is-25dB, the resident S criterion in community is-114dB, close transmitting of measuring instrument when being tested, when terminal test, to signal during lower than-114dB, triggering terminal enters out the assessment of service area event.
Fig. 1 and Fig. 2 for above-mentioned two kinds of scenes, show when the signal of tester emission from-25dB bust to-108dB respectively or-during 120dB, the signal that terminal is measured decays to the simulation result of needed time actual signal near from-25dB.Here each real-time measurement values of putative signal is accurately and does not have deviously, and the filtering factor n of emulation gets a recommended value 0.25, and cell measuring modulation cycle T identical with paging receiving cycle under standby (agreement regulation 0.64s is to 5.12s).Below respectively the simulation result shown in Fig. 1 and Fig. 2 is analyzed.
For OLPC test, it is 0.25 o'clock that Fig. 1 shows filtering factor, the convergence process of the signal of tester emission terminal measurement result after filtering during from-25dB bust to-108dB, and wherein abscissa unit is the cell measuring modulation cycle under standby.From the simulation result of Fig. 1, when the converge to-106db of measurement result after after filtering is following, at least need 13 measuring periods.But, in the OLPC test, the transmission of up link open loop power is generally all carried out in 10 cycles after signal intensity.Like this, the path loss of utilizing filtered measurement result to calculate can be forbidden, and makes the up link open loop power calculated make mistakes, thereby causes test crash.Here, emulation provides is from-decay to-108dB of 25dB scene, in fact for measuring instrument from-be switched to-25dB of 108dB scene, exist too path loss calculation to be forbidden to cause the up link open loop power to calculate the situation of makeing mistakes.
For OOS, test, it is 0.25 o'clock that Fig. 2 shows filtering factor, the convergence process of the signal of tester emission decay to-114dB of terminal measurement result after filtering during from-25dB bust to-120dB, wherein abscissa unit is the cell measuring modulation cycle under standby.From the simulation result of Fig. 2, filtered measurement result converges to-needs below 114db 10 measuring periods.Yet this simulation result is based on ideally and draws.When terminal is carried out to actual test, for the scene more than the sudden change of the sort signal on measuring instrument 80db, the automatic gain of terminal is controlled (AGC) adjustment also needs a process.Therefore, the actual time that detects service area and enter no net state of terminal can be far longer than 10 measuring periods.
As can be seen here, existing filtering processing mode can not be applicable to top these two kinds of special screnes.

Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are explained in more detail and illustrate.Should be understood that, drawings and the embodiments of the present invention are only for exemplary effect, not for limiting the scope of the invention.
Describe embodiments of the present invention in detail referring to accompanying drawing.
Fig. 3 shows the flow chart of the method 300 of the measurement result for definite cell signal according to the embodiment of the present invention.
As shown in Figure 3, after method 300 starts, at step S301, store the transient measurement value of the predetermined number of the cell signal strength that the cell measurement of nearest predetermined number obtains.
For example, along with the carrying out of cell measurement, nearest (M+1) the inferior individual instantaneous value RscpReal of (M+1) measured (j) of storage (j=0 ..., M), the initial value of these values is all default empirical value K (unit is for example dB).
(i+M) inferior cell measurement instantaneous value is RscpNew (i+M), and wherein i is positive integer.Before (i+M) inferior cell measurement results is processed:
RscpReal(0)＝RscpNew(i-1)
……
RscpReal(M)＝RscpNew(i+M-1)
Next, at step S302, the transient measurement value of the predetermined number of storage and first threshold and Second Threshold are compared.
For example, this (M+1) inferior transient measurement value RscpReal (j) compares with default empirical value K respectively recently.K can comprise a higher first threshold and a lower Second Threshold.
Then, method 300 advances to step 303.At step S303, if the transient measurement value of predetermined number all higher than first threshold or all lower than Second Threshold, the current transient measurement value of the cell signal strength current area measured is defined as the current measurement result of cell signal; Otherwise current transient measurement value is carried out to the filtering processing, and filtered current transient measurement value is defined as to the current measurement result of cell signal.
For example, if (M+1) inferior transient measurement value is all higher than higher thresholds or all lower than low threshold value recently, just directly adopt the measurement result of the transient measurement value of current area measurement as community, otherwise this measurement is carried out to the filtering processing, obtain final cell measurement results Rscp.
In one embodiment, store the measurement result of cell signal definite in cell measurement as historical measurement result Rscp_history, and carry out more new historical measurement result by the measurement result of cell signal newly definite in the cell measurement of back, that is:
Rscp_history＝RscpNew(i+1)
In one embodiment, the historical measurement result based on storage is carried out the filtering processing with filtering factor to current transient measurement value.
Particularly, can realize current transient measurement value or filtered current transient measurement value are defined as by adjusting filtering factor the current measurement result of cell signal.For example, filtering factor n is revised as to 1, means to abandon filtering, directly adopt the measurement result of current instantaneous value as community.Otherwise filtering factor n gets normal value A.A means the value of filtering factor (0<A<1) under normal circumstances.Based on historical measurement result, to the filtering of current transient measurement value, can carry out with reference to formula (1).
According to the embodiment of the present invention, after (i+M) inferior measured value is carried out to the filtering processing, RscpReal (j) is upgraded, specific as follows:
RscpReal(0)＝RscpNew(i)
……
RscpReal(M)＝RscpNew(i+M)
Afterwards, physical layer can utilize the filtered measurement result Rscp in community for calculating the associated uses such as path loss.Physical layer can also report the agreement high level by filtered cell measurement results Rscp, with the assessment reference value as cell reselection, switching, the event such as resident.
Here, the value of threshold k can reference terminal in the real work power bracket of outfield net environment.For example, the following value of low can get-100dB of threshold value in K, for example, between arrive-105dB of-102dB; And the above value of can get-30dB of the higher thresholds in K.
When-100dB is following, although can also proceed various tests on measuring instrument, under external field environment, basically can not carry out normal business and resident when power.Therefore, now can consider the problem of Ping-Pong gravity treatment and switching in external field environment.And needing only the cell measurement value higher than KdB, new processing mode just can not come into force in terminal.Therefore, processing policy in this paper can not affect the actual performance of terminal in outfield.Simultaneously, the processing mode of continuous N time transient measurement value before the reference adopted here, can be for example in the situation that be used measuring instrument to carry out to terminal the generation that sensitivity test greatly reduces erroneous judgement.
Like this, in the ideal case, during signal acute variation on the measuring instrument that terminal is carried out to sensitivity test: (1) signal is when dying down by force, through general M after the measuring period, the measurement result of community can directly adopt the transient measurement value to replace filter value, to assess for the event of carrying out and the calculating of path loss; (2) when signal changes from weak to strong, as measuring instrument by cell power from-be switched to-25dB of 108dB, equally through general M after the measuring period, the measurement result of community can directly adopt the transient measurement value to replace filter value, thereby accelerates the speed that filtered measurement result converges to the community actual signal.
Below in conjunction with Fig. 4, the device 400 of the measurement result for definite cell signal according to the embodiment of the present invention is described.As shown in Figure 4, install 400 and comprise memory cell 401 and determining unit 402.
