Description
Technical field
The triggering method that is reported the present invention relates to mutual interference in wireless communication field, more particularly to a kind of terminal and it is
System.
Background technology
With the development of radiotechnics and intelligent terminal, in order to support the different communication demand of terminal client,
Seek integrated various wireless technologys, two or more wireless module in same terminal device (UE, User Equipment)
Can be communicated with its peer-entities simultaneously.
As shown in figure 1, in the prior art one simultaneously using the UE schematic diagrames of three kinds of radiotechnics, in the UE,
Respectively using the module 11 of Long Term Evolution (LTE, Long Term Evolution) technology, the specifications of IEEE Std 802.11 are used
WLAN (WLAN, the Wireless Local Area Networks) module 12 of technology, i.e. WLAN of regulation
Website (WLAN STA), the module 13 of bluetooth (Bluetooth) radiotechnics specified using IEEE Std802.15 specifications.
11st, it is connected by the interface (inter-radio interface) between radiotechnics between 12,13 3 modules, for example：
It is connected by L101 between module 11 and module 12, is connected by L102 between module 12 and module 13；Module 11 and module 13
Between be connected by L103, or three modules are controlled by a public control module 14.
In Fig. 1, three modules of UE carry out radio communication with the opposite equip. corresponding to respective radiotechnics respectively, its
In, module 11 carries out radio communication, module 12 with LTE evolved base stations (eNB, E-UTRAN NodeB) 15 by air interface
Radio communication, module 13 and another Bluetooth equipment 17 are carried out by air interface with another WLAN STA equipment 16
Radio communication is carried out by air interface.
When the module of various radiotechnics is set in same UE, in view of UE finite volumes, certainly will mean simultaneously
It is designed with two or more radiotechnics UE, the sky between the module of two or more radiotechnics
Between apart from close proximity, such as several centimetres even several millimeters, namely two or more radiotechnics is used
Antenna port between space isolation cannot design it is sufficiently large；So as to be easily caused when each radio in same UE
Technical work when adjacent frequency band, due to band outward leakage (out of band emission), spurious emissions (spurious
Emissions), the reason such as receiver obstruction (Blocking), it is when one of radio module is launched, interference is another
One reception of radio module, vice versa.And, existing wave filter technology cannot eliminate this adjacent frequency interference, so that
The communication quality of each radio module can be influenceed.Above-mentioned interference is referred to as mutual interference in equipment, and (ICO is disturbed, In-device
Coexistence Interference)。

Scientific and Medical) frequency band (2.4GHz~2.5GHz), wherein, WLAN channels are used in ISM band
2.4GHz~2.4835GHz frequency ranges, Bluetooth channels use the 2.4GHz~2.497GHz frequency ranges in ISM band.LTE's
Time division duplex (TDD, Time Division Duplex) pattern works in the (Band 40 of frequency band 40：2.3GHz~2.4GHz) and
(the Band 38 of frequency band 38：2.57GHz~2.62GHz)；FDD (FDD, Frequency Division Duplex) pattern
Uplink (Uplink Transmission) work in 2.5GHz~2.57GHz frequency ranges of frequency band 7 (Band 7), FDD moulds
The downlink transfer (Downlink Transmission) of formula works in the 2.62GHz~2.69GHz of Band 7.As shown in Fig. 2
ISM band Band 40, the uplink adjacent frequency bands of LTE fdd modes Band 7 just with LTE tdd modes.Therefore, such as
Fruit module 11 is using tdd mode and uses Band40, then will be interfered between module 11 and module 12, module 13；If
Module 11 is using fdd mode and uses Band 7, because upstream band and the ISM band of LTE Band 7 adjoin, therefore, module
11 up transmitting is by interference module 12 or the downlink reception of module 13.
The presence of mutual interference can reduce the communication quality of different radio power technology in intelligent terminal in equipment, with Fig. 3 institutes
As a example by the application shown, intelligent UE is configured with the LTE module and the module using WLAN technologies of LTE technologies, possesses wireless phase
The function of capacitive certification (WiFi, Wireless Fidelity) portable router (WiFi portable router).Wherein,
LTE eNB are communicated by air interface L301 with the LTE module of UE, the WLAN module of UE by air interface L302 with it is portable
Computer (Laptop) communicates.When the LTE module working frequency points of UE are 2.390GHz, WLAN module is in 2.401GHz~2.423GHz
Between band operation, the LTE module of UE carries out downlink reception and when WLAN module just sends data to Laptop simultaneously, LTE
Module can be disturbed by WLAN module.And WLAN module is to downlink reception that the data transmitted by Laptop are from LTE module
Obtain, the then interference of wlan device causes LTE module downlink data receiving efficiency low, have impact on WLAN moulds again in turn
Block sends the efficiency of data to Laptop, finally influences Consumer's Experience.Vice versa, i.e. the up transmission of LTE module can be disturbed
The reception of WLAN module, also can influence the two communication links of L301 and L302 simultaneously, finally influence Consumer's Experience.Therefore, press down
Control equipment content mutual interference is necessary.
AF panel flow common at present includes：Generation from UE to mutual interference in network side reporting equipment, network side
Provide suppression decision-making.And UE when to mutual interference in network side reporting equipment generation, for mutual interference in suppression equipment
Process is particularly significant.If UE report twice interference occur between time interval more than network can be given suppress decision-making when
Between, then the problems such as the power dissipation of UE, ascending control channel load can be caused to increase；If UE report interference occur not enough and
When, it will have a strong impact on Consumer's Experience, in some instances it may even be possible to the problems such as causing call drop.

Specific embodiment
The technical solution of the present invention is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
For the triggering for realizing mutual interference in equipment is reported, mutual interference is reported in a kind of terminal provided by the present invention
Triggering method, including：The parameter that mutual interference is reported in the triggering equipment of UE detection network side configurations, is judging to meet default
During interference report condition, to mutual interference in network side reporting terminal.
When the present invention coexists suitable at least two radiotechnics in equipment, mutual interference in triggering UE reporting equipments
Concrete mode.The UE refers to the user communication device that two or more radiotechnics coexists, including mobile phone, intelligence
The equipment such as energy mobile phone, portable communication device, personal data processor (PDA, Personal Digital Assistant).Institute
It refers to there are two or more wireless sets inside UE, specifically to state two kinds of radiotechnics and coexist：First wireless
Electric transceiver uses the first radiotechnics, is worked under the first radio communication protocol specification, and in agreement regulation
The transmitting-receiving of signal is carried out in frequency range；Second wireless set uses second radiotechnics, wireless at second
Worked under telecommunication protocol specification, and the frequency range specified in agreement carries out the transmitting-receiving of signal；The rest may be inferred.The first is wireless
The frequency range of power technology work is at least partly to overlap or adjacent with the frequency range that other radiotechnics work.
Described the first radiotechnics can be LTE technologies, UMTS (UMTS, Universal
Mobile Telecommunication System) technology, the Wimax technologies etc. using the specifications of IEEE 802.16, described
A kind of part working frequency of radiotechnics or the frequency of its harmonic wave have overlap or adjacent with ISM band；It is described that other are wireless
Power technology can be WLAN technologies, Bluetooth technologies, the ZigBee technology etc. using IEEE 802.15.4 specifications, it is described its
He works in ISM band at radiotechnics.
The content of mutual interference can be that the instruction of mutual interference in equipment is currently occurring in the UE reporting equipments
Information, and/or the frequency information for disturbing/not interfering with.Wherein, the frequency information of interference refers to：The first radio skill in UE
Art produces the frequency or frequency range of interference with other radiotechnics, and the frequency information not interfered with refers to：The first in UE
Radiotechnics will not produce the frequency or frequency range of interference with other radiotechnics.
The behavior of mutual interference in the UE reporting equipments refers to interior the first radio module of UE to its opposite equip.
(namely network side) carries out interference and reports.
The present invention includes two schemes, and both schemes are respectively suitable for different scenes.
Scene one：UE is received from UE using the data that the first radiotechnics sends using second radiotechnics
Data, UE can disturb UE to use the reception of second radiotechnics using transmissions of the first radiotechnics.It is corresponding
Concrete scheme (scheme one) includes：
UE, in the caching of UE, first is used to network side application using second data storage of radiotechnics reception
Plant mandate and resource that radiotechnics is transmitted；Network side is that UE allocating caches thresholding offsets BoffsetAnd interference is reported
Triggered time TTT1 (Time To Trigger), be that UE distribution sends the money of these data using the first radiotechnics
Source；UE starts the moment being transmitted using the first radiotechnics, and buffer status are Bmax；UE uses the first radio
After technology is transmitted, if the partially larger than B that buffer status Buffer declinesoffset, and the portion that buffer status Buffer declines
Divide and be more than BoffsetWhen duration exceedes the triggered time TTT1 that interference is reported, the first radio mould of triggering UE inside
Block is to mutual interference in network side reporting equipment.
Wherein, network side is the B of UE configurationsoffsetCan be a percentage, i.e., one with BmaxOn the basis of relative value；
Namely the part that real caching declines is relative to BmaxRatio reach Boffset, and the duration be more than TTT1 when triggering UE done
Disturb and report.
The flow chart that the triggering of this programme one UE reports interference is given as shown in Figure 4, is mainly included the following steps that：
Step 401, network side is that UE allocating caches thresholding offsets Boffset, interference report triggered time TTT1；UE opens the
During a kind of sending function of radiotechnics, its buffer status is Bmax.UE begins to use the first radiotechnics from caching
Data are taken out to be transmitted.
Step 402, since the moment that UE is transmitted using the first radiotechnics, UE persistently checks buffer status
Buffer。
Whether step 403, UE judged, judge part that buffer status decline more than Boffset, if so, then performing step
Rapid 404；If it is not, then performing step 402.
Step 404, UE judged, judges part that buffer status decline more than BoffsetWhether duration surpasses
TTT1 is crossed, if so, then performing step 405；If it is not, then performing step 402.
Step 405, UE carries out interference and reports.
It should be noted that if described the first radiotechnics uses LTE technologies, network side is UE allocating caches door
Limit skew BoffsetAnd the process of triggered time TTT1 that interference is reported can reconfigure (RRC connection in RRC connections
Reconfiguration completed during).
The application schematic diagram that to be as shown in Figure 5 LTE coexist with Bluetooth, the embodiment meets above-mentioned scene one, this
Embodiment is using the exemplary embodiments of scheme one：
Bluetooth earphone uses Bluetooth technologies, namely above-mentioned second radiotechnics, will by Radio Link L402
To UE, UE receives speech data to voice data transmission using Bluetooth technologies, and stores in the caching of itself；UE passes through
LTE technologies, namely above-mentioned the first radiotechnics, the speech data that will be received from bluetooth earphone in caching is by wireless
Link L401 is sent to the eNB of correspondent network side.
When mutual interference in generation equipment, UE inner buffer states are as shown in the curve in Fig. 6.Can from figure
Go out, mutual interference can cause call off and in equipment, have a strong impact on Consumer's Experience, it is impossible to ensure its service quality (QoS,
Quality of Service)。
During T0~T1：
T0 moment, UE receives data from bluetooth earphone using Bluetooth technologies, and stores in the caching of itself
In, the data in caching start to increase, and now LTE technologies do not start to send, therefore receive language using Bluetooth technologies
Sound data are not disturbed by LTE technologies；
The speech data that UE will be received from bluetooth earphone is stored in the caching of itself, and sends scheduling to network side
Request (SR, Scheduling Request) or buffer status report (BSR, Buffer Status Report), to net
Network side application resource carries out transmitting uplink data；
UE receives the uplink mandate (UL Grant) that network side is sent to UE, and the UL Grant inform what UE uses
Plant the contents such as coded system, the specific resource that transmission is used.
At the T1 moment, the buffer status of UE are Bmax, UE starts to carry out the data in caching using LTE technologies at the moment
Up transmission.
During T1~T2：
Because the up transmission of LTE technologies disturbs the reception of Bluetooth technologies, data in being cached within the time period
Can decline rapidly, the T2 moment, the part that data decline in the caching of UE reaches the buffer threshold skew that network is its configuration
Boffset。
During T2~T3：
Data continuous decrease in the caching of UE, and time span between T2 to T3 is more than the interference that network side is that it is configured
Report triggered time TTT1；
The T3 moment：UE is to mutual interference in network side reporting equipment.
Further, in order to ensure data cached decline because mutual interference is caused in equipment, rather than due to indigo plant
Tooth end stops what data is activation was caused, and an instruction is provided to UE when bluetooth side stops data is activation.UE is in this case
Just bluetooth will not be directed to and stops generation of the data cached decline in the case of sending to mutual interference in network-reporting equipment.
Herein it should be noted that the curve in Fig. 6 is the qualitative description to UE buffer data sizes, do not constitute to the present invention
Improper restriction.Network side carries out parameter setting according to actual transmissions situation and different service types, must is fulfilled in principle
The qos requirement of user.
Particularly, the working frequency range of GSM technology is not overlapped or adjacent with ISM band, but when the transmission up letters of GSM
Number when, if GSM just frequency hopping to low-frequency range, 3 order harmonicses of generation will disturb the signal for just being received from Bluetooth,
Therefore it is also applied for the scope of the invention.
Scene two：UE is received using the first radiotechnics, while UE is carried out using second radiotechnics
Send, UE can disturb UE using the reception of the first radiotechnics using the transmission of second radiotechnics.Corresponding tool
Body scheme (scheme two) includes：
Network side is UE configuration received signal quality thresholdings THq1The triggered time TTT2 reported with interference；In UE the first
Radio module is in data receiving state, while one or more of other radiotechnics in transmission data mode, UE
Received signal quality is detected using the first radiotechnics, if the received signal quality is less than the signal quality thresholding of setting
THq1, and the duration is more than the triggered time TTT2 that network side is that it is configured, then trigger the first radio module inside UE
To mutual interference in network side reporting equipment.
Wherein, the received signal quality refers to that the signal evaluation that UE receives the lateral UE transmissions of network by detecting is descending
The parameter of link-quality, the setting of the received signal quality thresholding, according to different radiotechnics, used it is different
The difference of signal is received, by network side concrete configuration.
The flow chart that the triggering of this programme two UE reports interference is given as shown in Figure 7, is mainly included the following steps that：
Step 701, network side is UE configuration received signal quality thresholdings THq1The triggered time TTT2 reported with interference.
Step 702, the first radio module in UE is in reception state, while other radio modules are in sending
During state, UE detection received signal qualities.
Whether step 703, UE judged, judge received signal quality less than THq1, if so, then performing step 704；If
It is no, then perform step 702.
Step 704, UE judged, judges that received signal quality is less than THq1Whether duration is more than TTT2, if
It is then to perform step 705；If it is not, then performing step 702.
Step 705, UE carries out interference and reports.
If described the first radiotechnics uses LTE technologies, network side is UE configuration received signal quality thresholdings THq1With
The process of the triggered time TTT2 that interference is reported can be completed during RRC connections are reconfigured.
The application schematic diagram that to be as shown in Figure 3 LTE coexist with WLAN, UE using LTE technologies by Radio Link L301 from
Data are received at eNB, while UE sends data by Radio Link L302 using WLAN technologies to Labtop.The hair of WLAN technologies
Send the reception of interference LTE technologies.
Network side when RRC connections are reconfigured for UE configuration measurement amounts be Reference Signal Received Quality (RSRQ,
Reference Signal Received Quality) A2 events, it is event triggered fashion that measurement report is reported.
The LTE module of UE is in and enables state simultaneously with WLAN module, and LTE module carries out downlink reception,
WLAN module is transmitted.When meeting the measurement report report condition of A2 events, mutual interference in triggering UE reporting equipments.
Here the measurement content of the LTE mechanism being related in embodiment is simply introduced：
Network side can send descending reference signal, and the reference signal power received by UE calculates RSRQ, and RSRQ is
One criterion of current service cell quality, network is that UE configures a thresholding of RSRQ, and the door is less than when RSRQ is met
Limit, and the duration more than triggered time (the Time To Tigger) that measurement report is reported when, UE is to network reporting measurement report
Accuse, content including network be its configuration measurement amount RSRQ value.
Said process is that the measurement report of an event triggering reports process, and serving cell signal intensity is less than setting thresholding
The as entry condition of A2 events.
Further, in order to accelerate UE triggering times for reporting of interference, can shorten measure the triggering for reporting in LTE mechanism
Time or the thresholding of raising RSRQ.
In addition, as another embodiment of the invention, it is dry using being coexisted in metering system triggering equipment in order to increase UE
Disturbing the credibility for reporting, i.e. UE give the correct time, and it is being subjected to mutual interference in equipment really, can be on the basis of scheme two
It is upper to add optional operation：
Network side is that UE configures the first received signal quality thresholding THq1It is UE during the triggered time TTT2 reported with interference
Configure the second received signal quality thresholding THq2The triggered time TTT3 and a signal quality reported with interference improve the time
Tr；UE is met when disturbing report condition in scheme two, does not report interference, interior other radio modules of UE arrestments to network
Transmission, continue detect the first radiotechnics received signal quality, when the signal quality is in time TrWithin lifted and arrive
Higher than the signal quality thresholding TH of settingq2, and received signal quality is higher than thresholding THq2Duration more than setting triggering
During time TTT3, the first radio module of triggering UE inside is to mutual interference in network side reporting equipment.
The flow chart that this programme triggering UE reports interference is given as shown in Figure 8, is mainly included the following steps that：
Step 801, network side is that UE configures the first received signal quality thresholding THq1The triggered time reported with interference
TTT2。
Step 801-1, network side is that UE configures the second received signal quality thresholding THq2, triggered time for reporting of interference
TTT3 and signal quality improves time Tr。
Step 802, the first radio module in UE is in reception state, while other radio modules are in sending
During state, UE detection received signal qualities.
Whether step 803, UE judged, judge received signal quality less than THq1, if so, then performing step 804；If
It is no, then perform step 802.
Step 804, UE judged, judges that received signal quality is less than THq1Whether duration is more than TTT2, if
It is then to perform step 805；If it is not, then performing step 802.
The transmission of other radio modules in step 805, UE pass hull closures.
Step 806, UE detection received signal qualities.
Whether step 807, UE judged, judge received signal quality in TrInside it is elevated above THq2, if so, then holding
Row step 808, if it is not, then performing step 802.
Step 808, UE judged, judges that received signal quality is higher than THq2Duration whether more than TTT3, if
It is then to perform step 809；If it is not, then performing step 802.
Step 809, UE carries out interference and reports.
Application examples as shown in Figure 3 is continued with, network side is when RRC connections are reconfigured for UE configuration measurement amounts are reference
The A2 events of signal receiving quality (RSRQ, Reference Signal Received Quality) and A1 event (Serving cells
Signal intensity is the entry condition of A1 events higher than setting thresholding), it is event triggered fashion that measurement report is reported.And network
When RRC connections are reconfigured for UE configuration signal qualitys improve time Tr。
The LTE module of UE is in and enables state simultaneously with WLAN module, and LTE module carries out downlink reception,
WLAN module is transmitted.When meeting the measurement report report condition of A2 events, the hair of the WLAN module that UE is closed in LTE
Send, if improving time T in signal qualityrWithin RSRQ higher than setting thresholding, then UE when the measurement report of A1 events is reported, to
Mutual interference in network side reporting equipment.
Fig. 9 show UE in scene two and changes over time curve using the received signal quality of the first radiotechnics and shows
It is intended to：At the T1 moment, received signal quality is less than setting thresholding THq1；Last till the T2 moment, received signal quality is still less than setting
Thresholding THq1, and T2-T1 >=TTT2, according to described in scheme two, UE can report interference at the T2 moment to network side.
Optionally, UE can not report interference at the T2 moment, close the transmission of other radiotechnics in UE, if receiving
Signal quality is at the T3 moment higher than setting thresholding THq2, and T3-T2≤Tr；Last till the T4 moment, received signal quality is still above
Setting thresholding THq2, and during T4-T3 >=TTT3, UE reports interference at the T4 moment.Can so ensure to be coexisted in UE reporting equipments dry
The credibility disturbed.
Explanation is needed exist for, each parameter value in Fig. 9 is qualitative description, does not constitute inappropriate limitation of the present invention,
For example：Two thresholding THq1With THq2Relation can be with equal, can TH as shown in the figureq1<THq2, it is also possible to meet THq1>THq2。
The size of TTT1, TTT2, TTT3 is determined by network side.
Additionally, in order to further optimize the triggering mode that UE reports interference, network side can be in UE configurations interference twice
The minimum interval of report, the minimum interval ensures that UE once reports interference and the preceding time once reported between interference to be more than after
Set minimum interval.For example, network side can be that mutual interference reports timer in UE configuration equipment：UE is on first time
In report equipment during mutual interference, start the timer；During the timer runs, UE must not report interference；Wait the timer
After time-out, when the condition that triggering interference is reported meets again, UE can perform interference and report, and above give the correct time and restart this regularly
Device.
As can be seen from the above-described embodiment, the communications status of UE are different, and its corresponding interference report condition is also different.Specifically
Including：
If the 1, UE is sent using its first internal radio module and uses second number of radio module reception
According to, then it is corresponding interference report condition be：Sent using its first internal radio module from UE and use second nothing
The moment of the data that line electricity module is received, UE checks the part of buffer status decline more than BoffsetAnd the duration exceedes
Default first interference of network side reports triggered time TTT1, and is not due to second radio module and stops reception causing
's；
The 2nd, if UE receives data using its first internal radio module, second of its inside is wireless
Electric module sends data, then corresponding interference report condition is：UE detection received signal qualities are less than THq1, and continue
Time, the second interference default more than network side reported triggered time TTT2；
The 3rd, if UE receives data using its first internal radio module, second of its inside is wireless
Electric module sends data, then corresponding interference report condition can also be：
