Description
Technical field
The present invention relates to dispose the subscriber equipment of multiple radiotechnics, relate in particular to a kind of method and device of measuring processing.
Background technology
Along with the continuous development of radiotechnics, increasing radiotechnics begins to be employed, and especially, in order to satisfy user's multiple communication requirement, the phenomenon that disposes two or more different radiotechnicss in a subscriber equipment (UE) is more and more general.
Fig. 1 is for disposing LTE (Long Term Evolution simultaneously, Long Term Evolution), WLAN (Wireless Local Area Network, WLAN (wireless local area network)) and the structural representation of the UE of Bluetooth (bluetooth) technology, as shown in Figure 1, subscriber equipment 100 comprises the module that has disposed three kinds of radiotechnicss, is respectively the LTE module 101 of using Long Term Evolution; Use the WLAN module 102 of the wireless local area network technology of IEEE Std 802.11 regulation and stipulations, i.e. wireless LAN station (WLAN Station); Use the bluetooth module 103 of the bluetooth radio of IEEE Std 802.15 regulation and stipulations, three modules among the above-mentioned UE also can be called LTE subset, WLAN subset and bluetooth subset.Three modules respectively and separately pairing opposite end UE of radiotechnics are carried out radio communication, and wherein radio communication is carried out by air interface in LTE module 101 and LTE base station (E-UTRAN NodeB, eNB is also referred to as evolved base station) 104; WLAN module 102 is carried out radio communication with another WLAN STA equipment 105 by air interface; Bluetooth module 103 carries out radio communication with another bluetooth equipment 106 by air interface.
In Fig. 1, link to each other by the interface (inter-radio interface) between the radiotechnics of UE inside between three modules, link to each other by the first interface L101 such as between LTE module 101 and the WLAN module 102, link to each other by the second interface L102 between LTE module 101 and the bluetooth module 103; Link to each other by the 3rd interface L103 between WLAN module 102 and the bluetooth module 103; Perhaps, three modules are controlled by a public control module 107.
This subscriber equipment that disposes multiple radio technology modules can be mobile phone, smart mobile phone, portable communication device, personal digital assistant (PDA, Personal Digital Assistant) etc.When same UE supports multiple different radiotechnics, because UE finite volume, use the space length between the module (being also referred to as radio technology modules) of this two or more radiotechnics to be separated by closer, like this, can't make the space isolation between the employed antenna port of this two or more radiotechnics enough big, this can cause the interval between the employed frequency of various radiotechnicss that same UE supports big inadequately, thereby outer reveal (Out of band emission) can appear being with, spurious emissions (Spurious emissions) and receiver block phenomenons such as (Blocking) (it is obstructed just to revise the back), when one of them radio technology modules transmits, with the reception of disturbing another radio technology modules to signal, vice versa.And this interference can't eliminate by existing filter, thereby influences the communication quality of each radio technology modules.Claim in this area that this adjacent interference phenomenon frequently is " (ICO, In-device Coexistence Interference) disturbed in coexistence in the equipment ".
WLAN and Bluetooth use " industry, science and medical treatment (ISM; Industrial Scientific and Medical) " frequency band (2.4GHz～2.5GHz), wherein WLAN uses the 2.4GHz～2.4835GHz frequency range in the ISM frequency band, and Bluetooth uses the 2.4GHz～2.497GHz frequency range in the ISM frequency band.Fig. 2 is ISM 2.4GHz～2.5GHz frequency band and adjacent LTE/ universal mobile telecommunications system (UMTS thereof, Universal Mobile Telecommunications System) distribution schematic diagram of frequency band, as shown in Figure 2, as can be seen from the figure ISM frequency band and LTE frequency band 40/UMTS frequency band c (2.3GHz～2.4GHz) adjacent, the upstream band (2.5GHz～2.57GHz) adjacent of ISM frequency band and LTE frequency band 7/UMTS frequency band VII.
With UE shown in Figure 1 100 is example, if LTE module 101 is used time division duplex (TDD, Time Division Duplex) pattern and service band 40, and the interval between the operating frequency of the operating frequency of LTE module 101 and WLAN module 102, bluetooth module 103 is hour, between LTE module 101 and WLAN module 102, the bluetooth module 103 with mutual interference mutually.As shown in Figure 2, if LTE module 101 is used Frequency Division Duplexing (FDD) (FDD, Frequency Division Duplex) pattern and service band 7, because the downstream bands and the ISM frequency band a good distance off of LTE frequency band 7, therefore the up emission of WLAN module 102/ bluetooth module 103 does not disturb the downstream signal of LTE module 101 to receive, but because the upstream band and the ISM frequency band of LTE frequency band 7 adjoin, interval between the operating frequency of the operating frequency of LTE module 101 and WLAN module 102/ bluetooth module 103 hour, the up emission of LTE module 101 will be disturbed the downstream signal reception of WLAN module 102/ bluetooth module 103.
When multiple different radiotechnics coexists as UE, the existence of above-mentioned ICO will reduce the communication quality of this multiple different radiotechnics, influence user's communications and experience.Therefore need in time to detect ICO and disturb, take necessary interference avoidance process measure.With the UE that disposes two kinds of radio technology modules (first radio technology modules and second radio technology modules) is example, for avoiding ICO to disturb, can change the working frequency points of first radio technology modules, make the frequency interval of winning between the radio technology modules and second radio technology modules enough big, this is a kind of frequency division multiplexing (FDM, Frequency Division Multiplexing) interference avoidance technique; Perhaps can coordinate the transmission time of first radio technology modules and second radio technology modules, make both transmission times stagger mutually, this is a kind of time division multiplexing (TDM, Time Division Multiplexing) interference avoidance technique.
Yet, no matter adopt which kind of ICO interference avoidance technique, such as above cited FDM or TDM interference avoidance technique, the capital produces certain influence to system resource or user experience, to cause the reduction even the waste of system spectrum service efficiency as the FDM technology, thereby and the TDM technology will cause time-domain resource to be used rendeing a service to reduce causing the customer service throughput to descend.Therefore if the detection of ICO is untimely, inaccurate, even detect mistake, cause network to take unnecessary even measure is avoided in wrong interference, will reduce the system resource service efficiency, influence user experience.

Embodiment
Present embodiment with the relevant radio technology that disposes LTE technology (first radiotechnics) simultaneously and use the ISM frequency band (as WLAN, Bluetooth, be referred to as second radiotechnics) UE be example, the method of measuring processing of present embodiment is described when LTE is subjected to the interference of second radiotechnics.Need to prove, first radiotechnics of present embodiment also can be other wide area networks (the Wide Area Network except that LTE, WAN) technology, as GSM (Global System of Mobile communication, global system for mobile communications), UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system), CDMA (Code Division Multiple Access, code division multiple access inserts), Wimax (Worldwide Interoperability for Microwave Access, global inserting of microwave) etc.In the present embodiment, first radio technology modules, it is the LTE module, it is inner by different functions, can be divided into again physical layer (Layer1, L1), Radio Resource control (Radio Resource Control, RRC) layer etc., the L1 layer in the present embodiment, rrc layer all refer to the L1 layer and the rrc layer of LTE module among the UE.
In the existing LTE system, the LTE subscriber equipment passes through random measurement Reference Signal Received Quality (RSRQ, Reference Signal Received Quality) to detecting from the outer interference of equipment (disturbing such as the adjacent area).Wherein RSRQ is Reference Signal Received Power (RSRP, Reference Signal Received Power) with received signal intensity (RSSI, Received Signal Strength Indicator, comprise Serving cell, homogeneous-frequency adjacent-domain, alien frequencies adjacent area, various signal strength signal intensities such as thermal noise) ratio has reflected from coexistence in the equipment and has disturbed disturbed condition to the Serving cell signal.Because equipment disturbs outward and has continuity on time-domain (in a very long time, disturb continued presence), therefore UE can detect any subframe in measuring period at random, promptly the Interference Detection mechanism of existing LTE system is only applicable to exist the scene of steady and continuous interference, for example, from the interference of grand adjacent area.
LTE measurement model as shown in Figure 3, in order to eliminate shadow fading in the wireless space communication environments, enchancement factors such as rapid fading are to the influence of measurement result, taked a series of filtering measures in the LTE measurement model, with guarantee UE be notified to network measurement result reflection be algorithm average result in the long period.As the step 301:L1 filtering among Fig. 3, in order to prevent that the outer interference of equipment may be in some randomized jitter characteristic constantly, therefore UE is when measuring, the physical layer of UE can be measuring period with the certain time length, to carry out algorithm (be filtering on average to taking multiple measurements sampling (A among Fig. 3) in measuring period and these repeatedly being measured sampled result, step 301L1 filtering among Fig. 3) pass to the high-rise processing module (B among Fig. 3) of UE after again, RRC carries out further filtering (filter, step 302RRC filtering among Fig. 3), thus the randomized jitter of further anti-stop signal to the influence of measurement result.Rrc layer is through after the further filter, for guarantee further that UE is notified to the measurement result of network (being interference detection results) reflection be long-time relatively in the situation of signal and interference, to avoid network to take unnecessary behaviors such as switching, in the LTE system result after the rrc layer filter has been carried out the measurement report event assessment.With the Serving cell is example, network can dispose such as the A2 incident for UE, in a period of time that begins from a certain moment, such as TTT (Time of Trigger, triggered time) the RSRQ measurement result of interior Serving cell all satisfy the A2 incident of network configuration entry criteria (such as: the RSRQ＜thresholding of Serving cell), then UE is to the measurement result of network-reporting Serving cell; Otherwise if do not satisfy above-mentioned condition, then UE is not to the measurement result of network-reporting Serving cell.
As mentioned before, equipment disturbs outward has continuity on time-domain, coexistence is disturbed and then can't be guaranteed this characteristic in the equipment, shown in the schematic diagram that WLAN module in Fig. 4 equipment is disturbed the LTE module, the signal emission of wlan device has discontinuous characteristic or claims burst characteristic, this point is different from equipment to be disturbed outward, and such as the interference from grand adjacent area, grand adjacent area is in the persistent signal emission state for a long time.Therefore as shown in Figure 4, have only the time of corresponding WLAN module emission, promptly among the figure 401, the LTE module just can be subjected to disturbing from coexistence in the equipment of WLAN module, promptly among the figure 402.
Just because of be different from the outer continuation property of disturbing of equipment in the legacy network, coexistence is disturbed and is had discontinuous characteristic in the equipment, and the Interference Detection in the existing LTE system (promptly measuring) mechanism can't detect the interference in equipment.Given this, be illustrated in figure 5 as coexistence interferometry model in a kind of equipment, this measurement model is on the basis of the basic function that keeps existing LTE measurement model, according to having or not that coexistence in the equipment is disturbed, perhaps according to the strong and weak grade that coexists and disturb in the equipment, carry out the grouping Interference Detection, perhaps claimed grouping mea-sure.Need to prove, as not have specified otherwise, below the behavior of all UE all be meant the behavior of UELTE module, following L1 layer, rrc layer all refer to the L1 layer and the rrc layer of LTE module among the UE.The step of measuring processing in the equipment as shown in Figure 5 under the coexistence interferometry model comprises:
The L1 layer of step 500:UE carries out grouping mea-sure (perhaps claiming packet samples);
Structural representation according to as shown in Figure 1 UE, the L1 layer of UE can the control appliance 107 from Fig. 1 obtains the configuration informations such as radio frequency parameter of signal transmitting and receiving sequential, signal strength signal intensity, frequency and each radio technology modules Receiver And Transmitter of each radio technology modules, perhaps obtain above-mentioned configuration information by the interface between each submodule among Fig. 1, what coexistence was disturbed in the equipment of estimating to be subjected on each subframe of LTE (minimum transmission units of LTE is a subframe, and a subframe continues 1ms) according to the configuration information that gets access to has or not and strong and weak situation.The L1 layer is according to having or not and strong and weak situation that coexistence in the equipment that is subjected on each subframe of LTE is disturbed, with a measuring period be unit, the LTE subframe is divided into groups.
The group forming criterion of L1 layer specifically can be, according to having or not and power that coexistence in the equipment that is subjected on each subframe is disturbed, be divided into two and measure grouping, measure grouping 1 and measure grouping 2, wherein, measure and not to be subjected in the equipment coexistence on the subframe of grouping 1 and to disturb or exist in the equipment coexistence to disturb but a little less than disturbing, measure and existing in the equipment coexistence to disturb and disturb strong on the subframe of grouping 2.The L1 layer can disturb the emissive porwer of the radio technology modules transmitter of LTE module according to the receiving intensity of the above-mentioned LTE module by signal of obtaining; The frequency of the radio technology modules of LTE module and interference LTE module; The radio frequency parameter of LTE module receiver, disturb the parameters such as radio frequency parameter of the radio technology modules transmitter of LTE module, estimate the power of interference, the power of concrete interference can be by the configuration interference threshold, when coexistence is disturbed less than interference threshold in the equipment that is subjected on subframe, determine that coexistence is disturbed in the equipment that subframe is subjected to a little less than; Otherwise if greater than interference threshold, coexistence is disturbed strong in the equipment that then definite subframe is subjected to.Interference threshold can set up on their own and be solidificated in the UE by each UE production firm, also can be notified to UE by network.
The group forming criterion of L1 layer can also be, according to the strong and weak grade that coexistence in the equipment that is subjected on each subframe is disturbed, is divided into a plurality of measurements groupings, measure grouping 1 (500-1), measure grouping 2 (500-2) ..., measure grouping N (500-N).Coexistence disturbs strong and weak grade identical in the equipment that is subjected on each subframe in each is measured and divides into groups, and respectively measures the strong and weak grade difference of coexistence interference in the equipment that is subjected on each subframe between the grouping.Need be provided with a plurality of interference thresholds this moment.
The L1 layer is measured grouping to each and is carried out repeatedly sampled measurements to be a measuring period after unit divides into groups to the LTE subframe in measuring period.In the process that UE measures, the L1 layer continues the LTE subframe in next measuring period is divided into groups and sampled measurements after finishing a measuring period.
The L1 layer of step 501:UE is measured the repeatedly sampled measurements result who divides into groups to go up in a measuring period to each and is carried out filtering, and filtered result is passed to the rrc layer of UE;
The rrc layer of step 502:UE carries out filtering respectively to each measurement result of measuring in the grouping that the L1 layer passes over;
Concrete, the filtering of rrc layer can be that one is measured in the grouping, and it is average that L1 passes to the algorithm of repeatedly measurement result of rrc layer, also can be other filtering methods.
The rrc layer of step 503:UE is measured grouping to each and is upward carried out the incident assessment through the filtered result of rrc layer, such as the assessment of A2 incident, A1 incident assessment etc.
At last, shown in D among Fig. 5, UE is to network reporting measurement result.
According to 503 incident assessment results, after in N the measurement grouping as long as the measurement result process incident assessment of a grouping being arranged, satisfy event condition, such as at the A2 incident, as long as measure and have any one to be grouped in the entry criteria that interior measurement result of TTT time all satisfies the A2 incident in the grouping for N, then UE is to the network reporting measurement reports.Report the measurement result of the measurement grouping of satisfying event condition in the measurement report, further, the measurement result of the measurement grouping of not satisfying event condition can also be reported in the measurement report, further, the proportionate relationship information of number of sub-frames in all each groupings can also be reported in the measurement report.Such as, if in the step 500 L1 with one measuring period 200ms be that duration has been divided into into 2 and measures grouping, measure in the grouping 1 and have 50 subframes, measure in the grouping 2 and have 150 subframes, then the proportionate relationship of described number of sub-frames can be that measurement grouping 1 is 1/4, and measuring grouping 2 is 3/4.
Fig. 6 is the another kind of interferometry model based on Fig. 5, among Fig. 6, in the step 600 during L1 measurement/sampling, do not divide into groups, L1 carries out repeatedly sampled measurements in measuring period, step 601, when L1 carries out filtering to described repeatedly sampled result, the L1 layer earlier among the control appliance 107 from Fig. 1 or Fig. 1 the interface between each submodule obtain configuration information, estimate interior the having or not and strong and weak situation of coexisting and disturb of equipment on each subframe of LTE, according to having or not and strong and weak situation that coexistence in the equipment on the subframe that is sampled is disturbed, the above-mentioned repeatedly sampled result that obtain corresponding with the subframe that is sampled to be divided into groups, group technology adopts the explanation of step 500 among Fig. 5.L1 carries out filtering to each measurement result of measuring in the grouping then, and filtered result is passed to the rrc layer of UE; Step 602, step 603 and Fig. 6 D point UE are to network reporting measurement result's the behavior description with Fig. 5.
Disturb for coexistence in the checkout equipment, introduced the grouping mea-sure model among Fig. 5 and Fig. 6.For the reliability of coexistence interference detection results in the further assurance equipment, the measurement processing method of present embodiment comprises following measurement treatment mechanism:
UE carries out grouping mea-sure, and UE only reports the measurement result of the measurement grouping of satisfying the certainty of measurement requirement.Based on the grouping mea-sure model of Fig. 5 or Fig. 6, UE only reports the measurement result that satisfies the certainty of measurement requirement to be:
(1) L1 course rrc layer reports the measurement result of the measurement grouping of satisfying the certainty of measurement requirement.
Shown in Fig. 5 step 500 or 501, perhaps shown in Fig. 6 step 601, L1 finds when carrying out grouping mea-sure (500) or packet filtering (501 or 601) that the measurement result of some measurement groupings can't satisfy the requirement of certainty of measurement, then the L1 layer does not report the measurement result of this measurement grouping to rrc layer, and promptly the L1 layer only reports the measurement result of the measurement grouping of satisfying the certainty of measurement requirement to rrc layer.
(2) rrc layer reports the measurement result of the measurement grouping of satisfying the certainty of measurement requirement to network.
Shown in D point among D point or Fig. 6 among Fig. 5, the rrc layer of UE carries out before the rrc layer filtering to the result in each measurement grouping, perhaps after the filtering, perhaps through after the incident assessment, rrc layer from Fig. 1 control appliance 107 or Fig. 1 in interface between each submodule obtain configuration information, what coexistence was disturbed in the equipment on each subframe of estimation LTE has or not and strong and weak situation, the measurement result of judging some measurement groupings can't satisfy the certainty of measurement requirement, then rrc layer does not report the measurement result of this measurement grouping to network, and promptly rrc layer only reports the measurement result of the measurement grouping of satisfying the certainty of measurement requirement to network.
Concrete, the requirement of certainty of measurement is stipulated by consensus standard, perhaps is notified to UE by network.
Below lift specific embodiment explanation UE of the present invention and carry out grouping mea-sure, UE only reports the measurement processing method of the measurement result of the measurement grouping of satisfying the certainty of measurement requirement.
Embodiment 1:
As Fig. 7 A is the sequential schematic diagram that the LTE Serving cell is disturbed by other radio technology modules in a kind of equipment, two measuring periods have been illustrated among the figure, the situation that Serving cell is disturbed by other radio technology modules in the equipment in measuring period 701 and measuring periods 702.In the present embodiment, the grouping mea-sure of UE is based on as shown in Figure 5 interferometry model.UE obtains configuration information according to the interface between each submodule among the control appliance among Fig. 1 107 or Fig. 1, what coexistence was disturbed in the equipment on each subframe of the Serving cell of estimation shown in Fig. 7 A has or not and strong and weak situation, in the present embodiment, the L1 layer with one measuring period 200ms to be chronomere be divided into two with each subframe of Serving cell measures grouping, measure grouping 1 and comprise the subframe that is shown with coexistence interference in the equipment as Fig. 7 A, measurement grouping 2 comprises does not have the subframe that coexistence is disturbed in the equipment shown in Fig. 7 A.
In the present embodiment, give the reliability of the interference detection results of network in order to guarantee the UE final notice, UE needs to satisfy the certainty of measurement requirement of the common frequency measurement of 3GPP (The 3rd Generation Partnership Project, third generation collaborative project) protocol specification 36.133 defineds two certainties of measurement of measuring in the grouping.Such as, be example with the frequency in the LTE Serving cell service band 40, RSRP's
(signal-to-jamming ratio) 〉=-situation of 3dB under, two certainties of measurement of measuring grouping require be, two measure measured value that grouping goes up RSRQ and the error between the RSRQ actual value-2.5dB～+ 2.5dB between, and as if RSRP's
(signal-to-jamming ratio) 〉=-situation of 6dB under, two certainties of measurement of measuring grouping require be, two measure measured value that grouping goes up RSRQ and the error between the RSRQ actual value-4dB～+ 4dB between.In order to satisfy above-mentioned certainty of measurement requirement, suppose that the UE ability is in the present embodiment, measure grouping for each, UE need measure 4 times in each measuring period at least, promptly on 4 subframes, sample respectively, and each sampling interval just can reach above-mentioned certainty of measurement requirement greater than 20ms at least.In addition, in the present embodiment, network has disposed the A2 incident for the Serving cell of this UE.
Based on as shown in Figure 5 interferometry model and measurement processing method of the present invention, Fig. 7 B is the flow process that present embodiment is measured the method for processing, comprising:
Step 701:L1 layer with one measuring period 200ms to be chronomere be divided into two with each subframe of Serving cell measures grouping;
Step 702:L1 layer is according to the set UE ability of present embodiment, L1 judges that measuring grouping 1 all has only 2 possible sampled points (dividing into groups 1 to comprise 2 subframes) in measuring period 701 and measuring period 702, be less than the requirement of at least 4 sampled points of UE Capability Requirement, therefore can't satisfy the certainty of measurement requirement, so L1 only carries out grouping mea-sure to measuring grouping 2;
Step 703:L1 layer also carries out filtering to the measurement result of measuring in the grouping 2, then filtered result is passed to rrc layer;
Step 704:RRC layer carries out rrc layer filtering and the assessment of A2 incident to the measurement result of the measurement grouping 2 that L1 passes over, if measure the entry criteria that the measurement result of grouping 2 all satisfies the A2 incident in the TTT incident, then UE is to the network reporting measurement reports.
At this moment, do not satisfy the certainty of measurement requirement owing to measure grouping 1, so the measurement result of a reporting measurement grouping 2 in the measurement report, the measurement result of reporting measurement grouping 1 does not need reporting measurement grouping 1 yet and measures the proportionate relationship of the number of sub-frames of grouping 2.
Embodiment 2:
