Description
Technical field
The present invention relates to the user equipment for configuring a variety of radiotechnics, more particularly to a kind of method for measuring processing
And device.
Background technology
With the continuous development of radiotechnics, more and more radiotechnics start to be employed, especially, in order to full
A variety of communication requirements of sufficient user, the phenomenon of the two or more different radiotechnics of configuration is got in a user equipment (UE)
Come more universal.
Fig. 1 is to be configured with LTE (Long Term Evolution, Long Term Evolution), WLAN (Wireless Local at the same time
Area Network, WLAN) and Bluetooth (bluetooth) technology UE structure diagram, as shown in Figure 1, user
Equipment 100 includes the module for being configured with three kinds of radiotechnics, respectively using the LTE module 101 of Long Term Evolution；Use
The WLAN module 102 of wireless local area network technology, i.e. wireless LAN station (WLAN as defined in 802.11 specifications of IEEE Std
Station)；Using the bluetooth module 103 of bluetooth radio as defined in 802.15 specifications of IEEE Std, in above-mentioned UE
Three modules can also be referred to as the sub- equipment of LTE equipment, WLAN and the sub- equipment of bluetooth.Three modules are respectively and each wireless
Opposite end UE progress wireless communications corresponding to power technology, wherein LTE module 101 and LTE base station (E-UTRAN NodeB, eNB,
Referred to as evolved base station) 104 wireless communication is carried out by air interface；WLAN module 102 and another WLAN STA equipment 105
Wireless communication is carried out by air interface；Bluetooth module 103 carries out channel radio with another bluetooth equipment 106 by air interface
Letter.
In Fig. 1, the interface (inter-radio between the radiotechnics inside UE is passed through between three modules
Interface) it is connected, for example is connected between LTE module 101 and WLAN module 102 by first interface L101, LTE module 101
It is connected between bluetooth module 103 by second interface L102；Connect between WLAN module 102 and bluetooth module 103 by the 3rd
Mouth L103 is connected；Alternatively, three modules are controlled by a public control module 107.
This user equipment for being configured with a variety of radio technology modules can be mobile phone, smart mobile phone, portable
Communication equipment, personal digital assistant (PDA, Personal Digital Assistant) etc..Same UE supports a variety of differences
Radiotechnics when, it is (also referred to as wireless using the module of two or more radiotechnics due to UE finite volumes
Power technology module) between space length be separated by closely, in this way, can not be made two or more radiotechnics
Space isolation between antenna port is sufficiently large, this various radiotechnics that same UE can be caused to be supported is made
Interval between frequency is not big enough, so that band outward leakage (Out of band emission), spurious emissions occur
Phenomena such as (Spurious emissions) and receiver obstruction (Blocking) (obstructed just after modification), when one of nothing
When line power technology module launches signal, reception of another radio technology modules to signal will be disturbed, vice versa.And this
Kind interference can not be eliminated by existing wave filter, so as to influence the communication quality of each radio technology modules.Claim this in this area
Kind adjacent frequency interference phenomenon is " mutual interference (ICO, In-device Coexistence Interference) in equipment ".
WLAN and Bluetooth uses " industry, science and medical treatment (ISM, Industrial Scientific and
Medical) " frequency band (2.4GHz~2.5GHz), wherein WLAN use 2.4GHz~2.4835GHz frequency ranges in ISM band,
Bluetooth uses 2.4GHz~2.497GHz frequency ranges in ISM band.Fig. 2 for ISM 2.4GHz~2.5GHz frequency bands and its
Adjacent LTE/ Universal Mobile Communication System (UMTS, Universal Mobile Telecommunications System) frequency
The distribution schematic diagram of band, as shown in Fig. 2, as can be seen from the figure ISM band and LTE frequency band 40/UMTS frequency bands c (2.3GHz~
2.4GHz) adjacent, ISM band is adjacent with the upstream band (2.5GHz~2.57GHz) of LTE frequency band 7/UMTS frequency bands VII.
By taking the UE 100 shown in Fig. 1 as an example, if LTE module 101 uses time division duplex (TDD, Time Division
Duplex) pattern and service band 40, and the working frequency of LTE module 101 and WLAN module 102, the work of bluetooth module 103
When interval between working frequency is smaller, it will be interfered with each other between LTE module 101 and WLAN module 102, bluetooth module 103.Such as figure
Shown in 2, if LTE module 101 uses frequency division duplex (FDD, Frequency Division Duplex) pattern and service band 7,
Due to the downstream bands and ISM band a good distance off of LTE frequency bands 7, the uplink of 102/ bluetooth module 103 of WLAN module is launched
The downstream signal reception of LTE module 101 is not disturbed, but the upstream band due to LTE frequency bands 7 is adjoined with ISM band, works as LTE
When interval between the working frequency of 102/ bluetooth module 103 of working frequency and WLAN module of module 101 is smaller, LTE module
101 uplink transmitting will disturb the downstream signal reception of 102/ bluetooth module 103 of WLAN module.
When a variety of different radiotechnics coexist in UE, the presence of above-mentioned ICO will reduce a variety of different radio
The communication quality of technology, influences the communication experiences of user.Therefore detection ICO interference in time is needed, takes necessary interference to avoid
Treatment measures.To be configured with two kinds of radio technology modules (the first radio technology modules and the second radio technology modules)
Exemplified by UE, to avoid ICO from disturbing, thus it is possible to vary the working frequency points of the first radio technology modules so that the first radiotechnics
Frequency interval between module and the second radio technology modules is sufficiently large, this is a kind of frequency division multiplexing (FDM, Frequency
Division Multiplexing) interference avoidance technique；Or the first radio technology modules and the second radio can be coordinated
The transmission time of technology modules so that both transmission times mutually stagger, this is a kind of time division multiplexing (TDM, Time
Division Multiplexing) interference avoidance technique.
However, which kind of ICO interference avoidance technique no matter is used, for example FDM cited hereinabove or TDM interference avoids skill
Art, all can produce certain influence, as FDM technology will cause system spectrum service efficiency to system resource or user experience
Reduce and even waste, and TDM technologies will cause time-domain resource to be reduced using effect so as to cause customer service throughput degradation.Cause
It is inaccurate if the detection of this ICO is not in time, or even detection mistake, cause network to take unnecessary or even wrong do
Avoiding measures are disturbed, system resource service efficiency will be reduced, influence user experience.

Embodiment
Present embodiment with the same time be configured with LTE technologies (the first radiotechnics) and using ISM band it is related wirelessly
Exemplified by the UE of power technology (such as WLAN, Bluetooth, are referred to as the second radiotechnics), illustrate when LTE is subject to the second radio
When technology is disturbed, the method for measuring processing of present embodiment.It should be noted that the first radio of present embodiment
Technology can also be other wide area network (Wide Area Network, WAN) technologies in addition to LTE, such as GSM (Global
System of Mobile communication, global system for mobile communications), UMTS (Universal Mobile
Telecommunications System, Universal Mobile Communication System), CDMA (Code Division Multiple
Access, CDMA access), and Wimax (Worldwide Interoperability for Microwave Access, entirely
Ball inserting of microwave) etc..In present embodiment, different functions is pressed in the first radio technology modules, i.e. LTE module, its inside, again
Physical layer (Layer1, L1), wireless heterogeneous networks (Radio Resource Control, RRC) layer etc., this reality can be divided into
The L1 layers in mode are applied, rrc layer refers both to the L1 layers and rrc layer of LTE module in UE.
In existing LTE system, LTE user equipmenies pass through random measurement Reference Signal Received Quality (RSRQ, Reference
Signal Received Quality) interference (such as adjacent area interference) outside equipment is detected.Wherein RSRQ is ginseng
Examine signal reception power (RSRP, Reference Signal Received Power) and received signal strength (RSSI,
Received Signal Strength Indicator, including serving cell, homogeneous-frequency adjacent-domain, alien frequencies adjacent area, thermal noise etc. are each
Kind of signal strength) ratio, reflect in equipment mutual interference to the disturbed condition of serving cell signal.Outside due to equipment
Interference has continuity (for example in a very long time, disturbing continued presence) in time-domain, therefore UE can be at random to surveying
Any subframe in the amount cycle is detected, i.e., the Interference Detection mechanism of existing LTE system is only applicable to that there are steady and continuous to do
The scene disturbed, for example, the interference from grand adjacent area.
LTE measurement models as shown in Figure 3, in order to eliminate shadow fading in wireless space communication environments, rapid fading etc. with
Influence of the machine factor to measurement result, takes a series of filtering measures in LTE measurement models, to ensure that UE is notified to network
Measurement result reflection be algorithm average result in the long period.Such as the step 301 in Fig. 3：L1 is filtered, and is set in order to prevent
Standby outer interference may be in the randomized jitter characteristic at some moment, therefore UE, when measuring, the physical layer of UE can be with a timing
A length of measurement period, to taken multiple measurements in measurement period sampling (A in Fig. 3) and to these repeatedly measurement sampled results into
The high-rise processing module (B in Fig. 3) of UE is passed to after row algorithm average (filtering, the step 301L1 filtering in Fig. 3) again,
RRC is further filtered (the step 302RRC filtering in filter, Fig. 3), so that further the random of anti-stop signal is trembled
The dynamic influence to measurement result.Rrc layer passes through after further filter, in order to further ensure UE notifies the survey to network
Amount result (i.e. interference detection results) reflection is relatively long interior signal and the situation of interference, and being taken to avoid network need not
The behaviors such as the switching wanted, have carried out measurement report event assessment in LTE system to the result after rrc layer filter.With service
Exemplified by cell, network can be that UE configures such as A2 events, in such as a period of time since a certain moment, such as TTT (Time
Of Trigger, triggered time) interior serving cell RSRQ measurement results all meet network configuration A2 events entry criteria
(such as：The RSRQ ＜ thresholdings of serving cell), then measurement results of the UE to network report services cell；, whereas if it is unsatisfactory for
Above-mentioned condition, then UE is not to the measurement result of network report services cell.
As it was noted above, disturbed outside equipment has continuity in time-domain, and mutual interference can not then ensure in equipment
This characteristic, as shown in the schematic diagram of WLAN module interference LTE module in Fig. 4 equipment, the signal transmitting of wlan device is with non-
Continuation property claims burst characteristic, and this point is different from disturbing outside equipment, for example the interference from grand adjacent area, grand adjacent area are long-term
In persistent signal emission state.Therefore as shown in figure 4, the time of only corresponding WLAN module transmitting, i.e., 401, LTE moulds in figure
Block can just be subject to mutual interference in the equipment from WLAN module, i.e., 402 in figure.
Just because of different from the continuation property disturbed outside equipment in traditional network, mutual interference has discontinuous spy in equipment
Property, the Interference Detection in existing LTE system (measures) mechanism and can not detect from the interference in equipment.In consideration of it, such as Fig. 5
Mutual interference measurement model in a kind of equipment is shown, which is retaining the basic function of existing LTE measurement models
On the basis of, according to the presence or absence of mutual interference in equipment, or the rank order according to mutual interference in equipment, it is dry to have carried out packet
Detection is disturbed, or claims grouping mea-sure.It should be noted that as not having specified otherwise, the behavior of all UE below each means UELTE
The behavior of module, L1 layers following, rrc layer refers both to the L1 layers and rrc layer of LTE module in UE.Coexisted in equipment as shown in Figure 5 dry
Disturbing the step of measuring processing under measurement model includes：
Step 500：The L1 layers of UE are grouped measurement (or claiming packet samples)；
According to the structure diagram of UE as shown in Figure 1, the L1 layers of UE can obtain respectively from the control device 107 in Fig. 1
The signal transmitting and receiving sequential of radio technology modules, signal strength, frequency and each radio technology modules Receiver And Transmitter
Configuration informations such as radio frequency parameter, or above-mentioned configuration information is obtained by interface between each submodule in Fig. 1, according to getting
Configuration information estimation each subframes of LTE (minimum transmission units of LTE are a subframe, and a subframe continues 1ms) on be subject to
The presence or absence of mutual interference and strong and weak situation in equipment.L1 layers have according to mutual interference in the equipment being subject in each subframes of LTE
Nothing and strong and weak situation, in units of a measurement period, are grouped LTE subframes.
L1 layers of group forming criterion can be specifically, according to the presence or absence of mutual interference in the equipment being subject in each subframe and by force
It is weak, it is divided into two measurement packets, measurement packet 1 and measurement packet 2, wherein, it is not subject in the subframe of measurement packet 1 in equipment
Mutual interference or still disturbed there are mutual interference in equipment it is weak, measurement packet 2 subframe on there are mutual interference in equipment
And interference is strong.The L1 layers of radiotechnics that LTE module according to the receiving intensity of the LTE module signal of above-mentioned acquisition, can be disturbed
The emissive porwer of module transmitter；The frequency of the radio technology modules of LTE module and interference LTE module；LTE module receiver
Radio frequency parameter, disturb the parameters such as the radio frequency parameter of radio technology modules transmitter of LTE module, estimate interference power,
The power specifically disturbed can be by configuring interference threshold, and mutual interference is less than interference threshold in the equipment that is subject in subframe
When, determine that mutual interference is weak in the equipment that subframe is subject to；Conversely, if more than interference threshold, it is determined that in the equipment that subframe is subject to
Mutual interference is strong.Interference threshold by each UE production firms sets itself and can be solidificated in UE, can also be by network advertisement
To UE.
L1 layers of group forming criterion is also possible that the rank order according to mutual interference in the equipment being subject in each subframe, point
Into it is multiple measurement packet, measurement packet 1 (500-1), measurement packet 2 (500-2) ..., measurement packet N (500-N).It is each to survey
Mutual interference rank order is identical in the equipment being subject in amount packet in each subframe, and respectively measures and be subject in each subframe between packet
Equipment in mutual interference rank order it is different.Need to set multiple interference thresholds at this time.
After L1 layers are grouped LTE subframes in units of a measurement period, to each measurement point in measurement period
Group carries out multiple repairing weld measurement.During UE is measured, L1 layers after a measurement period, are continued to next
LTE subframes in measurement period are grouped and sampled measurements.
Step 501：The L1 layers of UE to multiple repairing weld measurement result in a measurement period in each measurement packet into
Row filters, and filtered result is passed to the rrc layer of UE；
Step 502：The measurement result in each measurement packet that the rrc layer of UE passes over L1 layers is filtered respectively；
Specifically, the filtering of rrc layer can be in a measurement packet, L1 passes to the multiple measurement results of rrc layer
Algorithm is average or other filtering methods.
Step 503：The rrc layer of UE carries out event evaluation to passing through the filtered result of rrc layer in each measurement packet, than
Such as A2 event evaluations, A1 event evaluations etc..
Finally, as shown in D in Fig. 5, UE is to network report measurement results.
According to 503 event evaluations as a result, as long as the measurement result for having a packet in N number of measurement packet passes through event evaluation
Afterwards, event condition is met, such as A2 events, as long as having the survey that any one was grouped in the TTT times in N number of measurement packet
Amount result all meets the entry criteria of A2 events, then UE is to network reporting measurement reports.Reported in measurement report and meet event bar
The measurement result of the measurement packet of part, can also further, in measurement report report the measurement packet for not meeting event condition
Measurement result, further, the proportionate relationship information of number of sub-frames in all packets can also be reported in measurement report.Than
Such as, if L1 divide into 2 measurement packets using a measurement period 200ms as duration altogether in step 500, shared in measurement packet 1
50 subframes, measurement are grouped in 2 and share 150 subframes, then the proportionate relationship of the number of sub-frames can be that measurement packet 1 is 1/
4, measurement packet 2 is 3/4.
Fig. 6 is another interferometry model based on Fig. 5, in Fig. 6, when L1 is measured/sampled in step 600, without
Packet, L1 carry out multiple repairing weld measurement in measurement period, step 601, when L1 is filtered the multiple repairing weld result, L1
First the interface from the control device 107 or Fig. 1 in Fig. 1 between each submodule obtains configuration information to layer, estimates each height of LTE
The presence or absence of mutual interference and strong and weak situation in equipment on frame, according to the presence or absence of mutual interference in the equipment in the subframe sampled
With strong and weak situation, a pair multiple repairing weld result obtained above corresponding with the subframe sampled is grouped, and group technology uses
The explanation of step 500 in Fig. 5.Then L1 is filtered the measurement result in each measurement packet, and by filtered result
Pass to the rrc layer of UE；Step 602, description of the behavior of step 603 and Fig. 6 D point UE to network report measurement results with Fig. 5.
For mutual interference in detection device, grouping mea-sure model is introduced in Fig. 5 and Fig. 6.In order to further ensure equipment
The reliability of interior mutual interference testing result, the measurement processing method of present embodiment include following measurement processing mechanism：
UE is grouped measurement, and UE only reports the measurement result for the measurement packet for meeting measurement accuracy requirement.Based on Fig. 5 or
The grouping mea-sure model of Fig. 6, UE, which is only reported, meets that the measurement result that measurement accuracy requires can be：
(1) the L1 layers of measurement result that the measurement packet for meeting measurement accuracy requirement is reported to rrc layer.
As shown in Fig. 5 steps 500 or 501, or as shown in Fig. 6 steps 601, L1 is grouped measurement (500) or packet
Measurement result of some measurement packet is found when filtering (501 or 601) can not meet the requirement of measurement accuracy, then L1 layers not to
Rrc layer report the measurement be grouped measurement result, i.e. L1 layer only reported to rrc layer meet measurement accuracy requirement measure be grouped
Measurement result.
(2) rrc layer reports the measurement result for the measurement packet for meeting measurement accuracy requirement to network.
As shown in D points in D points in Fig. 5 or Fig. 6, the rrc layer of UE carries out rrc layer filtering to the result in each measurement packet
Before, either by rrc layer each son from the control device 107 or Fig. 1 in Fig. 1 after event evaluation after either filtering
Interface between module obtains configuration information, estimates in each subframes of LTE the presence or absence of mutual interference and strong and weak situation in equipment, sentences
The measurement result that some measurement is grouped of breaking can not meet measurement accuracy requirement, then rrc layer does not report the measurement to be grouped to network
Measurement result, i.e., rrc layer only reported to network meet measurement accuracy requirement measurement packet measurement result.
Specifically, the requirement of measurement accuracy is provided by consensus standard, or by network advertisement to UE.
Specific embodiment is lifted below and illustrates that UE of the present invention is grouped measurement, and UE only reports the survey for meeting measurement accuracy requirement
Measure the measurement processing method of the measurement result of packet.
Embodiment 1：
Such as the time diagram that Fig. 7 A are disturbed for LTE serving cells in a kind of equipment by other radio technology modules, figure
In illustrate two measurement periods, serving cell is by other radiotechnics in equipment in measurement period 701 and measurement period 702
The situation of module interference.In the present embodiment, the grouping mea-sure of UE is based on interferometry model as shown in Figure 5.UE is according in Fig. 1
Control device 107 or Fig. 1 in interface between each submodule obtain configuration information, estimate serving cell as shown in Figure 7 A
The presence or absence of mutual interference and strong and weak situation in equipment in each subframe, in the present embodiment, L1 layers using a measurement period 200ms as
Each subframe of serving cell is divided into two measurement packets by chronomere, and measurement packet 1, which includes to have in equipment as shown in Figure 7 A, to be coexisted
The subframe of interference, measurement packet 2 are included as shown in Figure 7 A without the subframe of mutual interference in equipment.
In the present embodiment, in order to ensure reliability of the UE final notices to the interference detection results of network, UE is in two surveys
Measurement accuracy in amount packet be required for meeting 3GPP (The 3rd Generation Partnership Project, the 3rd
For collaborative project) protocol specification 36.133 defined common frequency measurement measurement accuracy requirement.For example made with LTE serving cells
Exemplified by the frequency in frequency band 40, RSRP'sIn the case of/Iot (signal-to-noise ratio) >=-3dB, what two measurements were grouped
Measurement accuracy requirement is, the errors between the measured values and RSRQ actual values of two upper RSRQ of measurement packet -2.5dB~+
Between 2.5dB, and if RSRP'sIn the case of/Iot (signal-to-noise ratio) >=-6dB, the measurement accuracy of two measurement packets
It is required that being, the error between the measured value and RSRQ actual values of two upper RSRQ of measurement packet is between -4dB~+4dB.In order to
Meet above-mentioned measurement accuracy requirement, it is assumed that UE abilities are in the present embodiment, are grouped for each measurement, UE is at least needed each
Measurement 4 times, i.e., sampled respectively in 4 subframes in measurement period, and the sampling interval could reach at least above 20ms every time
To the requirement of above-mentioned measurement accuracy.In addition, in the present embodiment, network is that the serving cell of the UE is configured with A2 events.
Based on interferometry model as shown in Figure 5 and measurement processing method of the present invention, Fig. 7 B are the present embodiment
The flow of the method for processing is measured, including：
Step 701：Each subframe of serving cell is divided into two measurements by L1 layers using a measurement period 200ms as chronomere

Step 702：The L1 layers of UE abilities according to set by the present embodiment, L1 judge measurement packet 1 in measurement period 701 and measurement
There was only 2 possible sampled points (packet 1 includes 2 subframes) in cycle 702, at least four less than UE Capability Requirements is adopted
The requirement of sampling point, therefore can not meet measurement accuracy requirement, therefore L1 is only grouped measurement to measurement packet 2；
Step 703：L1 layers and to measurement packet 2 on measurement result be filtered, then filtered result is transmitted
To rrc layer；
Step 704：The measurement result for the measurement packet 2 that rrc layer passes over L1 carries out rrc layer filtering and A2 events are commented
Estimate, if the measurement result of measurement packet 2 all meets the entry criteria of A2 events in TTT events, UE reports survey to network
Amount report.
At this time, since measurement packet 1 is unsatisfactory for measurement accuracy requirement, a reporting measurement is grouped 2 in measurement report
The measurement result of measurement result, not reporting measurement packet 1, it is not required that the number of sub-frames of reporting measurement packet 1 and measurement packet 2
Proportionate relationship.
