Description
Technical field
The present invention relates to the technical field that in terminal, multiple radiotechnics coexists, particularly relate to a kind of measurement processing method and system of the terminal equipment when multiple radiotechnics coexists in same terminal equipment.
Background technology
Along with the development of radiotechnics, increasing radiotechnics starts to be widely used, and especially in order to meet the multiple communication requirement of terminal client, in same intelligent terminal, will use multiple radiotechnics simultaneously.
A kind of schematic diagram simultaneously using the terminal equipment of two or more radiotechnics as shown in Figure 1, in this terminal equipment 100, design employs three kinds of radiotechnicss, use Long Term Evolution (LTE respectively, LongTermEvolution) subset (or being called submodule) of technology, can be expressed as LTE subset 101; Use the WLAN (wireless local area network) (WLAN of IEEEStd802.11 regulation and stipulation, wirelesslocalareanetworks) subset (or being called submodule) of technology, can be expressed as WLAN-STA subset 102, here, WLAN-STA refers to wireless LAN station; Use the subset (or being called submodule) of bluetooth (Bluetooth) radiotechnics of IEEEStd802.15 regulation and stipulation, bluetooth subset 103 can be expressed as.These three subsets of terminal equipment 100 carry out radio communication with the opposite equip. corresponding to respective radiotechnics respectively, wherein LTE subset 101 and LTE evolved base station (eNB, E-UTRANNodeB) equipment 104 carry out radio communication by air interface; WLAN-STA subset 102 carries out radio communication from WLANSTA equipment 105 (WLANSTA equipment 105 is another WLANSTA equipment different with WLAN-STA subset) by air interface; Bluetooth subset 103 carries out radio communication from bluetooth equipment 106 (bluetooth equipment 106 is another bluetooth equipments different with bluetooth subset 103) by air interface.Wherein, described air interface can be expressed as airinterface.
In Fig. 1, LTE subset 101, WLAN-STA subset 102, be connected by the interface (inter-radiointerface) between radiotechnics between bluetooth subset 103 3 subsets, such as be connected by interface L101 between LTE subset 101 with WLAN-STA subset 102, be connected by interface L102 between LTE subset 101 with bluetooth subset 103; Or three subsets are controlled by same public control appliance 107.
Multiple radiotechnics can be possessed in same terminal equipment simultaneously.But in view of terminal equipment volume too little, certainly will mean when being designed with two kinds or two or more radiotechnicss in terminal equipment simultaneously, owing to being limited to the volume of this terminal equipment, thus cause the space length between the subset at two or more radiotechnics place to be separated by very closely producing interfering with each other to each other.Space length between the subset at such as two or more radiotechnics place may only be separated by several centimetres, that is, it is enough large that space isolation between the antenna port that two or more radiotechnics uses cannot design, thus cause when if each radiotechnics in same terminal equipment uses adjacent frequency band, due to band outward leakage (Outofbandemission), the reasons such as spurious emissions (Spuriousemissions), when in terminal equipment, the subset at one of them radiotechnics place is launched, the reception of the subset at another radiotechnics place certainly will be disturbed, vice versa.And the interfering with each other and cannot be eliminated by existing filter to each other of the subset at this radiotechnics place, thus affect the communication quality of the subset at each radiotechnics place, above-mentioned this interference is referred to as mutual interference in equipment herein.
For the terminal equipment 100 shown in Fig. 1, WLAN and Bluetooth uses industry, science and medical treatment (ISM, IndustrialScientificandMedical) frequency band, this frequency band range is 2.4GHz ~ 2.5GHz, wherein WLAN uses the 2.4GHz ~ 2.4835GHz frequency range in ISM frequency band, and Bluetooth uses the 2.4GHz ~ 2.497GHz frequency range in ISM frequency band.ISM frequency band is just in time adjacent with the upstream band (Band7UP:2.5GHz ~ 2.57GHz) of frequency band 7 with the frequency band 40 (Band40:2.3GHz ~ 2.4GHz) of LTE, as shown in Figure 2.If therefore LTE subset 101 uses time division duplex (TDD, TimeDivisionDuplex) pattern and uses Band40, then will mutually disturb between LTE subset 101 and WLAN-STA subset 102, bluetooth subset 103.If LTE subset 101 uses Frequency Division Duplexing (FDD) (FDD, FrequencyDivisionDuplex) pattern and use Band7, then as shown in Figure 2, due to downstream bands and the ISM frequency band a good distance off of LTEBand7, therefore the downlink reception of LTE subset 101 is not disturbed in the up transmitting of WLAN-STA subset 102/ bluetooth subset 103, but because the upstream band of LTEBand7 and ISM frequency band adjoin, therefore the up transmitting of LTE subset 101 will the downlink reception of interference WLAN-STA subset 102/ bluetooth subset 103.
Following table 1, for LTEBand40 and WLANISMBand, illustrates the disturbed condition between the different frequency sub-band of LTEBand40 frequency sub-band different from WLANISMBand.
Table 1
Disturbed condition is as shown in Table 1 known: if LTE subset 101 is operated in the high band (such as 2375 ~ 2390MHz) of Band40, and WLAN-STA subset 102 is operated in the low-frequency range (such as 2412 ~ 2422MHz) of ISMBand, because the frequency interval between LTE subset 101 and WLAN-STA subset 102 operating frequency is very little, cause mutual interference in equipment very large.If LTE subset 101 is operated in the high band (such as 2375 ~ 2390MHz) of Band40, and WLAN-STA subset 102 is operated in the high band (such as 2432 ~ 2472MHz) of ISMBand; Or LTE subset 101 is operated in the low-frequency range (such as 2310 ~ 2365MHz) of Band40, and WLAN-STA subset 102 is operated in the low-frequency range (such as 2412 ~ 2422MHz) of ISMBand, frequency interval between LTE subset 101 and WLAN-STA subset 102 operating frequency is relatively large, in equipment, mutual interference exists, but does not have the former serious.Relative, if LTE subset 101 is operated in the low-frequency range (such as 2310 ~ 2365MHz) of Band40, and WLAN-STA subset 102 is operated in the high band (such as 2432 ~ 2472MHz) of ISMBand, frequency interval then between LTE subset 101 and WLAN-STA subset 102 operating frequency is enough large, there is not mutual interference in equipment.
In sum, coexist in mutual interference in the equipment in terminal equipment due to multiple radiotechnics and will reduce the communication quality of each radiotechnics in terminal equipment, affect the communication experiences of user, therefore, at present in the urgent need to a kind of measurement processing solution, on the frequency sub-band as far as possible avoiding allowing the various radio-based electronic devices coexisted in terminal equipment be operated in causing mutual interference in strong equipment, such as avoid allowing LTE subset 101 be operated in the high band of Band40, to reduce mutual interference in equipment.But there is not such solution at present.

Be described in further detail below in conjunction with the enforcement of accompanying drawing to technical scheme.
The solution of the present invention is a kind of measurement processing scheme reducing mutual interference in equipment, propose when the radio-based electronic devices at multiple radiotechnics place coexists in same terminal equipment, for the radio-based electronic devices at wherein a kind of radiotechnics place, the measurement processing scheme of such as LTE subset, Target cell can be found fast for LTE subset, LTE subset is when described Target cell communication, effectively can reduce even mutual interference in circumvention device, thus the communication quality improved when coexisting in multiple radiotechnics equipment, to the communication experiences that user is good.
A kind of measurement processing method, the method mainly comprises following content:
Scheme one:
Situation one included by scheme one is: not Differentiated Services cell measurement event and nearby region measurement event.
In such cases, such as LTE subset, when measuring the signal quality of Serving cell, a measure portion descending sub frame.Described part descending sub frame just in time can carry out the LTE descending sub frame of up transmission for corresponding to non-LTE subset (such as WLAN subset, bluetooth subset).
Situation two included by scheme one is: Differentiated Services cell measurement event and nearby region measurement event.
In such cases, such as LTE subset, when measuring the signal quality of Serving cell, distinguish and treat Serving cell measurement event and nearby region measurement event.
Further, for described Serving cell measurement event, UE, when measuring Serving cell, can measure any descending sub frame.
Further, for described nearby region measurement event, UE, can a measure portion descending sub frame to the measurement of Serving cell in nearby region measurement event.
Further, described part descending sub frame corresponds to the LTE descending sub frame that non-LTE subset (such as WLAN subset, Bluetooth subset) just in time carries out up transmission.Or further, on the basis selecting part descending sub frame, UE can adjust the described part descending sub frame selected according to the signal quality of active service community.
Further, carry out described adjustment to the described part descending sub frame selected to comprise: if the signal quality of Serving cell is higher than thresholding 1, then described part descending sub frame corresponds to the LTE descending sub frame that non-LTE subset (such as WLAN subset, bluetooth subset) does not carry out up transmission; If the signal quality of Serving cell is lower than thresholding 2, then described part descending sub frame corresponds to the LTE descending sub frame that non-LTE subset (such as WLAN subset, bluetooth subset) just in time carries out up transmission.Wherein, there is concrete elaboration after the description for " thresholding 1 ", " thresholding 2 ", do not repeat here.
Here it is pointed out that Serving cell measurement event, have two aspect functions, on the one hand, Serving cell measurement event is for measuring in detection legacy network the interference come from outside equipment; On the other hand, the measurement event of Serving cell, on this existing basis, for the situation of the multiple radiotechnics that coexists in equipment, comes from situation about disturbing in equipment for detecting further.Therefore under special scenes, such as UE is positioned at center of housing estate position, UE is subject to the interference come from outside equipment hardly, therefore for Serving cell measurement event, can only consider when measuring Serving cell to measure the interference detecting and come from equipment in time, namely can a measure portion descending sub frame, wherein, described part subframe refers to by the most obvious subframe of interference in equipment, such as WLAN subset is carrying out the subframe of up transmission, only measure described part subframe, UE can mutual interference in detecting devices in time, situation one goes for this type of special scenes.Certainly for this type of special scenes, for Serving cell measurement event, also can consider from the interference outside equipment when measuring Serving cell, considering that again, from the interference in equipment, therefore situation two is also applicable to this type of special scenes.Under another kind of special scenes, such as UE is positioned at cell edge position, UE may be subject to the interference come from outside equipment and the interference come from equipment simultaneously, therefore for Serving cell measurement event, need when measuring Serving cell to measure in time and detect the interference come from equipment and the interference come from outside equipment, therefore need to distinguish described Serving cell measurement event and nearby region measurement event, situation two goes for this type of special scenes.In situation one and situation two, for described nearby region measurement event, UE is to the measurement of Serving cell in nearby region measurement event, can a measure portion descending sub frame, described part subframe can refer to by the most obvious subframe of interference in equipment, such as WLAN subset is carrying out the subframe of up transmission, measure more targeted, the difference of the signal quality of neighbor cell and Serving cell can be compared as early as possible, thus nearby region measurement event can be triggered as early as possible, report candidate target cells to Serving cell, finally can reduce even mutual interference in circumvention device to greatest extent.
Further, described Serving cell measurement event, refers to the measurement event only need measuring serving cell signal quality, as A1 event, and A2 event.Relevant " A1 event ", has concrete elaboration after the description of " A2 event ", does not repeat here.
Further, described nearby region measurement event, refers to and namely needs to measure neighboring cell signal quality, also needs the measurement event measuring serving cell signal quality, as A3 event, and A5 event.Relevant " A3 event ", has concrete elaboration after the description of " A5 event ", does not repeat here.
Scheme two: be nearby region measurement event configuration interference offset, when assessing the signal quality of Serving cell in nearby region measurement event, UE deducts described interference offset in the measurement result of Serving cell.
In this programme, UE can coexist in by LTE subset and other radio-based electronic devices in equipment to know each subset operating state by the inter-radiointerface between subset or public control appliance (control appliance 107 in such as Fig. 1), therefore UE can predict mutual interference in the equipment that may exist, and by foreseen outcome (the such as operating state of each subset, operating frequency etc.) inform serving BS, serving BS can according to the announcement information of UE, after judging that UE is switched to which side frequency works, because the frequency interval between the operating frequency of these frequencies and interior other radio-based electronic devices (such as WLAN subset) of UE is enough large, even mutual interference in circumvention device can be reduced to greatest extent.Serving BS can be component frequency in these side frequencies described or all frequency configuration measure, when allocating and measuring, the nearby region measurement event configuration interference offset that serving BS configures for described measurement, and UE is when assessing the signal quality of Serving cell in described nearby region measurement event, UE deducts described interference offset in the measurement result of Serving cell.
Here, the content of the present invention and prior art is done a contrast to be described below:
The present invention is with LTE and ISM relevant radio technology (such as WLAN, it is example when Bluetooth) coexisting in same terminal equipment, illustrating when coexisting in the present invention's multiple radiotechnics equipment to reduce a kind of measurement processing scheme of mutual interference in equipment, it should be noted that measurement processing scheme of the present invention is applicable to situation when LTE and other radiotechnicss coexist in terminal equipment too.
In LTE system, in order to ensure business continuance, guarantee quality of service, after user sets up business, UE needs to measure Serving cell and neighbor cell according to the configuration of serving BS, to detect the signal quality of Serving cell in time, detect possible interference source and possible candidate handover target community, and meet to serving BS report the measurement report measuring configuration requirement.
In existing LTE system, for detecting the signal quality of Serving cell in time, serving BS can for the subscriber equipment (UE, UserEquipment) communicated with it, namely above-mentioned terminal equipment configuration is for the measurement event of Serving cell, specifically comprises A1 event and A2 event.Wherein the entry condition of A1 event is defined as: the signal quality of Serving cell is higher than predetermined threshold.After serving BS receives the measurement report of A1 event, know that the signal quality of Serving cell is fine, serving BS can be UE configuration pin to neighbor cell, the especially measurement of alien frequencies adjacent area.The entry condition of A2 event is defined as: the signal quality of Serving cell is lower than predetermined threshold.After serving BS receives the measurement report of A2 event, know that the signal quality of Serving cell is deteriorated, serving BS can be the measurement of UE configuration pin to neighbor cell in time.In the present invention, the measurement event only need measuring serving cell signal quality is called Serving cell measurement event, as above-mentioned A1 event, A2 event.
In existing LTE system, for detecting possible interference source and possible candidate handover cell, serving BS can for the UE configuration pin communicated with it be to the measurement event of neighbor cell, such as measurement event A3, measurement event A5.Wherein the entry condition of A3 event is defined as: the signal strength signal intensity high predetermined offset of the signal intensity ratio Serving cell of neighbor cell.After serving BS receives the measurement report of A3 event, the measurement result of the neighbor cell that can report according to measurement report, know that interference homogeneous-frequency adjacent-domain information carries out Inter-Cell Interference Coordination, or know the information of candidate target switching cell, UE is switched on a target handover cell.A5 event definition is: the signal quality of Serving cell is lower than predetermined threshold 1, and the signal quality of neighbor cell is higher than predetermined threshold.After serving BS receives the measurement report of A5 event, the measurement result of the neighbor cell that can report according to measurement report, knows the information of candidate target cells, and UE is switched on a target handover cell.In the present invention, both needing to measure neighboring cell signal quality, the measurement event measuring serving cell signal quality is needed again to be called nearby region measurement event, as above-mentioned A3 event, A5 event.
Wherein, signal quality refers to the Reference Signal Received Power (RSRP of measured community, ReferenceSignalReceivingPower) measurement result or Reference Signal Received Power quality (RSRQ, ReferenceSignalReceivedQuality) measurement result, wherein the measurement result of RSRQ can reflect the disturbed situation of Serving cell, if namely RSRQ measurement result is larger, then represent that Serving cell is disturbed stronger, otherwise then illustrate that Serving cell is disturbed very little or less.
All events all need the signal quality measuring Serving cell above, and when measuring Serving cell, UE can measure the cell reference signals (CRS, CellReferenceSignal) on any descending sub frame (downlinksubframe).All events all do not consider the situation of mutual interference in equipment when designing above.When there is multiple radiotechnics in same terminal equipment, because terminal equipment volume is too little, antenna port distance between the radio-based electronic devices coexisted in various equipment is very near, therefore when the frequency interval between the frequency that two kinds of radiotechnicss use is smaller, mutual interference in serious equipment will be caused, affect communication quality, therefore a kind of solution is as early as possible for LTE subset finds a Target cell, the operating frequency separation of other radio-based electronic devices coexisted in the operating frequency of this Target cell and equipment meets certain condition, thus ensure that LTE subset is when described Target cell communication, effective reduction is mutual interference in circumvention device even, and event designed in the LTE system of prior art cannot meet the demand.
In sum, adopt measurement processing scheme of the present invention, can for coexisting in the various radio-based electronic devices in terminal equipment, such as LTE subset finds Target cell fast, LTE subset is when described Target cell communication, effectively can reduce even mutual interference in circumvention device, thus improve communication quality when coexisting in multiple radiotechnics equipment, to the communication experiences that user is good.
Carry out citing to the present invention below to set forth.
Following examples are all for LTEBand40, LTE subset and WLAN subset are all with time division duplex work (TDM, TimeDivisionDuplex), be illustrated in figure 3 the transmission and reception time diagram of LTE and WLAN, wherein downlink reception time of LTE or up transmitting time can comprise one or more LTE subframe (subframe), and the duration of subframe is 1ms.If WLAN is just in time in the time of up transmission in the downlink reception time of LTE, the time period A in such as Fig. 3 and time period B, and frequency interval between LTE and WLAN is very little again, then LTE downlink reception by disturb by the up transmission of WLAN.Measurement processing scheme of the present invention, takes full advantage of the sequential relationship between above-mentioned LTE and WLAN, carries out for interference strong time period A and time period B.
Embodiment one: the description of corresponding such scheme one.
When measuring the signal quality of Serving cell, a measure portion descending sub frame.Or, when measuring the signal quality of Serving cell, distinguish and treat Serving cell measurement event and nearby region measurement event.Namely following two kinds of situations are divided into:
In existing LTE system, Serving cell measurement event, such as A1 event and A2 event, for detecting the signal quality of Serving cell, serving BS is known the signal quality of Serving cell according to A1 event, A2 event and is made and measure configuration decisions accordingly.Further, what the RSRQ measurement result of Serving cell characterized Serving cell is disturbed situation.And nearby region measurement event, such as A3, A5, may be used for measuring assessment candidate handover cell, serving BS knows the signal quality of neighbor cell and Serving cell according to A3 or A5 event, and according to the radio resource management policy of serving BS, and UE is switched on a suitable Target cell.All events all only considered the situation that equipment disturbs outward when designing above, do not consider the situation of mutual interference in equipment.
Situation one: measure portion descending sub frame during signal quality for above-mentioned measurement Serving cell, this does not distinguish the situation treating Serving cell measurement event and nearby region measurement event.The user communication quality caused for avoiding mutual interference in equipment declines and even interrupts, the present invention is when UE measures the signal quality of Serving cell, measure portion descending sub frame, concrete described part descending sub frame corresponds to the LTE descending sub frame that WLAN just in time carries out up transmission in the present embodiment, for Fig. 3, when UE measures serving cell signal quality, only measure the cell reference signals of Serving cell on time period A and all descending sub frames of time period B.The LTE descending sub frame just in time carrying out up transmission owing to corresponding to WLAN is subject to mutual interference in the very strong equipment coming from WLAN, therefore RSRQ measurement result is very little, A2 or A3 or A5 event can be triggered as early as possible and report measurement results to serving BS, serving BS can according to A2 event configuring adjacent cell measurement event as early as possible, or triggering blind handover is as early as possible switched to UE on same coverage cell, or serving BS can be known the signal quality of neighbor cell and Serving cell according to A3 or A5 event and in time UE is switched on Target cell according to the radio resource management policy of described serving BS, effectively avoid mutual interference.
Situation two: during signal quality for above-mentioned measurement Serving cell, Serving cell measurement event and nearby region measurement event are treated in differentiation, the present invention, when UE measures the signal quality of Serving cell, distinguishes and treats shown in being implemented as follows of Serving cell measurement event and nearby region measurement event:
One, for Serving cell measurement event, such as A1 event and A2 event, for detecting the signal quality of Serving cell, serving BS is known the signal quality of Serving cell according to A1 event, A2 event and is made and measure configuration decisions accordingly.Further, what the RSRQ measurement result of Serving cell characterized Serving cell is disturbed situation.Therefore, when having one or more radiotechnicss and LTE subset coexists, in order to more timely detect Serving cell be disturbed situation, for the measurement event of Serving cell, UE, when measuring Serving cell, measures the cell reference signals on any descending sub frame.For Fig. 3, concrete, cell reference signals in time shown in UE survey map 3 on all LTE descending sub frames, i.e. all subframes of Measuring Time section C and time period D, thus the measurement result of UE to Serving cell can be ensured, namely realize prior art and detect the object coming from equipment and disturb outward, realize again detecting the object coming from interference in UE internal unit.
Two, for nearby region measurement event, such as A3, A5, may be used for measuring assessment candidate handover cell, serving BS knows the signal quality of neighbor cell and Serving cell according to A3 or A5 event, and according to the radio resource management policy of serving BS, UE is switched on a suitable Target cell.And current A3, the design of A5 event is the situation of mutual interference in special consideration equipment not, therefore when in equipment, mutual interference exists, existing A3, A5 event cannot detect in time and find candidate target cells, thus make UE be subject to mutual interference in equipment for a long time in Serving cell, finally cause the downlink data of UE correctly cannot receive even more serious situation and cause UE, in Serving cell, Radio Link Failure occurs.Therefore the present invention is when processing nearby region measurement event, carry out special processing to the measurement of Serving cell, specific implementation comprises with under type:
When mode 1, measurement assessment nearby region measurement event, UE is to the measurement of Serving cell in nearby region measurement event, and a measure portion descending sub frame, in the present embodiment, specifically corresponds to the LTE descending sub frame that WLAN just in time carries out up transmission.For Fig. 3, when namely UE measures assessment nearby region measurement event, only measure the cell reference signals of Serving cell on time period A and all descending sub frames of time period B.
The entry condition of A3 event is defined as: the signal strength signal intensity high predetermined offset of the signal intensity ratio Serving cell of neighbor cell.Employing mode 1, UE only measures the LTE descending sub frame just in time carrying out up transmission corresponding to WLAN when measuring Serving cell, the LTE descending sub frame just in time carrying out up transmission owing to corresponding to WLAN is subject to mutual interference in the very strong equipment coming from WLAN, therefore RSRQ measurement result is very little, the A3 event of neighbor cell will be reported serving BS by rapid triggering, serving BS can be known the signal quality of neighbor cell and Serving cell according to described A3 event and in time UE is switched on Target cell according to the radio resource management policy of described serving BS, effectively avoid mutual interference.Frequency interval between the operating frequency of the ISM subset that coexists in the operating frequency of described Target cell and UE equipment (such as, WLAN-STA subset 102) is as shown in Figure 1 enough large.
In like manner the entry condition of A5 event is defined as: the signal quality of Serving cell is lower than predetermined threshold 1, and the signal quality of neighbor cell is higher than predetermined threshold.Employing mode 1, UE only measures the LTE descending sub frame just in time carrying out up transmission corresponding to WLAN when measuring Serving cell, the LTE descending sub frame just in time carrying out up transmission owing to corresponding to WLAN is subject to mutual interference in the very strong equipment coming from WLAN, therefore RSRQ measurement result is very little, the A5 event of neighbor cell will be reported serving BS by rapid triggering, serving BS can be known the signal quality of neighbor cell and Serving cell according to described A5 event and in time UE is switched on Target cell according to the radio resource management policy of described serving BS, effectively avoid mutual interference.Frequency interval between the operating frequency of the ISM subset coexisted in the operating frequency of described Target cell and UE equipment is enough large.
For Fig. 4, Cell1, Cell2 be two with cover or close to same coverage cell, the operating frequency (centre frequency) of Cell1 is 2380MHz (Band40), and the operating frequency of Cell2 is 1910MHz (Band33).UE is an intelligent terminal, possesses LTE subset and WLAN subset.The LTE subset of UE is current sets up business, a certain moment under Cell1, and the WLAN subset of UE opens, according to mode 1 of the present invention, after wlan device is opened, when UE measures the signal quality of Serving cell, distinguish and treat Serving cell measurement event and nearby region measurement event.Concrete, for Serving cell measurement event, such as A1, A2 event, measures all descending sub frames when UE measures Cell1, thus detects the interference come from outside equipment and in equipment in time; For nearby region measurement event, only measure the LTE descending sub frame just in time carrying out up transmission corresponding to WLAN when UE measures Cell1, Cell2 will trigger A3 event in time and report serving BS thus.
When mode 2, measurement assessment neighbor cell measurement event, such as A3, A5 event, depending on the signal quality of active service community, measures the part descending sub frame of Serving cell.If the signal quality of Serving cell is higher than thresholding 1, then when UE measures assessment neighbor cell measurement event, only measure and correspond to the LTE descending sub frame that WLAN does not carry out up transmission; If the signal quality of Serving cell is lower than thresholding 2, then when UE measures assessment neighbor cell measurement event, only measure and correspond to the LTE descending sub frame that WLAN just in time carries out up transmission.
Above-mentioned thresholding 1 and thresholding 2 configure to the threshold value of UE for serving BS, or the threshold value that serving BS and UE make an appointment.Further, thresholding 1 can be that in A1 event, serving BS configures to the threshold value of UE, and thresholding 2 can be that in A2 event, serving BS configures to the threshold value of UE.Further, thresholding 1 can be identical with thresholding 2 value.
Concrete, when the signal quality of Serving cell is higher than thresholding 1, interference is also not serious, and described interference is to the service quality (QoS of current the set up business of LTE subset, QualityofService) impact is very little, and UE can continue to keep business in Serving cell.If UE measures for the LTE descending sub frame just in time carrying out up transmission corresponding to WLAN, then likely UE just in time samples the very strong subframe of WLAN transmitting power, trigger A3 event, mislead serving BS and carry out unnecessary switching, therefore when the signal quality of Serving cell is higher than thresholding 1, when then UE measures assessment neighbor cell measurement event, only measure and correspond to the LTE descending sub frame that WLAN does not carry out up transmission.
Concrete, when the signal quality of Serving cell is lower than thresholding 2, disturb very serious, the QoS of survice of UE in Serving cell will can not be guaranteed, affect Consumer's Experience, when then UE measures assessment neighbor cell measurement event, only measure and correspond to the LTE descending sub frame that WLAN just in time carries out up transmission, the LTE descending sub frame just in time carrying out up transmission owing to corresponding to WLAN is subject to mutual interference in the very strong equipment coming from WLAN, therefore RSRQ measurement result is very little, neighbor cell measurement event will be reported serving BS by rapid triggering, serving BS can be known the signal quality of neighbor cell and Serving cell according to described neighbor cell measurement event and in time UE is switched on Target cell according to the radio resource management policy of described serving BS, effectively avoid mutual interference.
Be three neighbor cells for Fig. 5, Cell1, Cell2, Cell3, the operating frequency (centre frequency) of Cell1 and Cell3 is 2360MHz (Band40), and the operating frequency of Cell2 is 1910MHz (Band33).UE is an intelligent terminal, possesses LTE subset and WLAN subset.The LTE subset of UE is current sets up business under Cell1, and in addition, the WLAN subset of UE is also opened and established business with the wlan device corresponding to it, and WLAN subset is operated in the centre frequency of 2422MHz.The mobile alignment under Cell1 of UE is as shown in Fig. 5 band arrow solid line.According to mode 2 of the present invention, when UE is positioned at the point of A shown in Fig. 5, UE is near the center of housing estate position of Cell1, UE can not be subject to the interference from its homogeneous-frequency adjacent-domain Cell3, in addition, according to disturbed condition between table 1LTE and WLAN, quick big 10 ~ 50dB falls in the received power of up transmission to LTE subset of WLAN subset, therefore for LTE subset, the interference come from equipment and outside equipment is not strong especially, at Cell1, the signal quality of LTE subset Serving cell Cell1 can ensure that business is normally carried out higher than thresholding 1, LTE subset.Therefore when UE measures the signal quality of Serving cell, Serving cell measurement event and nearby region measurement event are treated in differentiation, concrete, for Serving cell measurement event, such as A1, A2 event, measures all descending sub frames when UE measures Cell1, thus detects the interference come from outside equipment and in equipment in time; For neighbor cell measurement event, only measure the LTE descending sub frame not carrying out up transmission corresponding to WLAN when UE measures Cell1, avoid unnecessary switching.
When UE moves to the B point shown in Fig. 5, UE is near the cell edge of Cell1, and the equipment be subject to from its homogeneous-frequency adjacent-domain Cell3 disturbs outward by UE, adds the interior interference of the equipment coming from WLAN, UE says at the signal quality of Cell1 and sharply declines, and has a strong impact on the quality of service of UE at Cell1.Therefore in order to sooner for UE finds suitable switching target small area, for neighbor cell measurement event, UE only measures the LTE descending sub frame just in time carrying out up transmission corresponding to WLAN when measuring Cell1, to trigger A3 as early as possible, A5 event, for UE finds suitable switching target small area, such as Cell2 is in the present embodiment (if UE is switched to Cell3, because Cell3 and Cell1 is with frequently, therefore UE is subject to coming from the interference outside equipment and in equipment by continuing at the cell edge of Cell3, therefore Cell3 is not suitable switching target small area).
Embodiment two: the description of corresponding such scheme two.
Scheme two, be nearby region measurement event configuration " interference offset ", in assessment nearby region measurement event during the signal quality of Serving cell, UE deducts described " interference offset " in the measurement result of Serving cell.
The current A3 event entry condition of LTE system is specifically defined as: the signal strength signal intensity high predetermined offset of the signal intensity ratio Serving cell of neighbor cell, i.e. (Mn+Ofn+Ocn)-Hys > (Ms+Ofs+Ocs)+Offset.
Wherein Mn is the measurement result of the signal of neighbor cell, Ofn is the frequency special parameter of place, neighbor cell frequency, Ocn is the cell-specific parameters of neighbor cell, (Mn+Ofn+Ocn) can think to assess in this measurement event after the signal strength signal intensity of neighbor cell.Hys is the lag parameter preventing ping-pong from setting.Ms is the measurement result of the signal of current service cell, and Ofs is the frequency special parameter of place, current service cell frequency, and Ocs is the cell-specific parameters of current service cell.(Ms+Ofs+Ocs) signal quality of Serving cell after can thinking to assess in this measurement event.Offset is predetermined offset.

Wherein Thresh1 is predetermined threshold 1, Thresh2 is predetermined threshold 2, and other parameters are with A3 Event Description.
Current A3, the design of A5 event is the situation of mutual interference in special consideration equipment not, therefore when in equipment, mutual interference exists, existing A3, A5 event cannot detect in time and find candidate target cells, thus make UE be subject to mutual interference in equipment for a long time in Serving cell, finally cause the downlink data of UE correctly cannot receive even more serious situation and cause UE, in Serving cell, Radio Link Failure occurs.
For detecting in time and finding candidate target cells, in the present invention program, be nearby region measurement event configuration " interference offset/skew " that, when assessing nearby region measurement event, the signal quality of Serving cell deducts described " interference offset/skew " in measurement result.
Concrete, for A3 event, described event is revised as: (Mn+Ofn+Ocn)-Hys > (Ms+Ofs+Ocs-X)+Offset.
Concrete, for A5 event, described event is revised as: Ms+Hys-X < Thresh1 and Mn+Ofn+Ocn-Hys > Thresh2.
Wherein X is described " interference offset/skew ", by the explicit configuration of serving BS to UE, or is made an appointment by serving BS and UE.
