Description

The method of up-downgoing proportioning switching and base station

Technical field

The present invention relates to the communications field, and more particularly, to the method for up-downgoing proportioning switching and base Stand.

Background technology

Long Term Evolution (Long Term Evolution, referred to as " LTE ") technology can be divided into from standard Time division duplex (Time Division Duplex, referred to as " TDD ") pattern and FDD (Frequency Division Duplex, referred to as " FDD ") pattern.It is same that tdd mode refers to that uplink downlink uses One working band, carries out the transmission of uplink and downlink signals in different time intervals, has between up-downgoing Protection interval；Fdd mode then refers to that uplink downlink uses different working band, can the most same time It is engraved in the transmission carrying out uplink and downlink signals on different frequency carriers, protected bandwidth between up-downgoing.Often The TDD system seen includes TD SDMA (the Time Division-Synchronous of 3G Code Division Multiple Access, referred to as " TD-SCDMA ") system and the time-division-LTE of 4G (Time Division-LTE, referred to as " TD-LTE ") system.

An a length of 10ms of radio frames in TDD, comprises special subframe and conventional subframe two class totally 10 Individual subframe, each subframe is 1ms.Special subframe is divided into 3 time slots: descending pilot frequency time slot (Downlink Pilot Time Slot, referred to as " DwPTS "), main protection time slot (Guard Period, referred to as " GP ") With uplink pilot time slot (Uplink Pilot Time Slot, referred to as " UpPTS "), wherein DwPTS For transmitting master sync signal (Primary Synchronization Signal, referred to as " PSS ")/physics Down control channel (Physical Downlink Control Channel, referred to as " PDCCH ")/thing Reason HARQ instruction channel (Physical Hybrid ARQ Indicator Channel, referred to as " PHICH ")/Physical Control Format Indicator Channel (Physical Control Format Indicator Channel, referred to as " PCFICH ")/Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as " PDSCH ") etc., GP protection interval between downlink and uplink, UpPTS For transmitting detection reference signal (Sounding Reference Signal, referred to as " SRS ")/physics RACH (Physical Random Access Channel, referred to as " PRACH ").Conventional Subframe includes sub-frame of uplink and descending sub frame, is used for transmitting uplink/downlink and controls signaling and business datum etc.. Wherein, in a radio frame, two special subframes, subframe can be configured in subframe #1 and subframe #6 DwPTS time slot in #0 and subframe #5 and special subframe is always used as downlink transfer, subframe #2 with And the UpPTS time slot in special subframe is always for uplink, other subframes can be joined according to needs Put and be used as uplink or downlink transfer.

The time slot division of uplink and downlink is usually fixed, it is common that according to little in network planning process The type in district and business proportion substantially determine that uplink and downlink timeslot ratio divides and keeps constant, proportioning mode Being broadcasted in the cell by system message, (User Equipment is referred to as the subscriber equipment of access " UE ") make the sub-frame configuration of UE keep consistent with community by receiving broadcast.Generally In the case of need to keep each neighboring interval proportioning consistent, the problem otherwise disturbed will be the most fatal, causes Between community, interference is acutely, it is impossible to correctly work.And after switching proportioning, do not affect the industry of local area and adjacent area In the case of business service quality (Quality of Service, referred to as " QoS "), farthest make Current up-downgoing proportioning matches with current traffic, and the capacity of Neng Shi community obtains gain.

Wireless backhaul (Wireless Backhual) technology is a kind of wireless backhaul technology, the solution of low cost Determined the backhaul difficult problem of base station, passback base station (Backhual eNodeB, referred to as " BeNB ") and Passback UE(Backhual UE, referred to as " BUE ") as the network element returned, to core net, base Stand, be all transparent for UE, play the signal wireless backhaul of UE to the function of core net, keep away Exempt from wired measure being deployed to core net from base station, significantly reduce operating expenses and construction period.Also make Obtain laying of base station more flexible.Owing to returning by wireless backhaul system, application scenarios be cover with Strengthening, homogeneous-frequency adjacent-domain quantity is few, and BUE and BeNB uses beam antenna, and interference will not be as grand Standing the strongest, this makes to use dynamic proportioning to have the strongest feasibility on return network.

Interference problem be cause current minizone can not the key factor of different ratio, existing program is by not Equidirectional subframe is set to empty frame, thus avoids interference.This mode is very big on portfolio impact, What proportioning adapted to purpose is exactly to improve the performance of whole system, if using empty frame, with purpose Disagree, it is impossible to improve the performance of whole system, and, if the high-frequency switching of proportioning, need big Amount signaling consumption goes to notify that adjacent area arranges empty frame, further, since X2 mouth signaling delay is likely larger than dynamic The cycle of state switching, it is difficult to ensure that real-time.

Fig. 1 shows the schematic stream of the method 100 of up-downgoing proportioning switching according to embodiments of the present invention Cheng Tu.The method 100 is performed by base station, as it is shown in figure 1, the method 100 includes:

S110, determines that this community needs to be switched to first object proportioning；

S120, disturbs information according to proportioning, determines that this this community is switched to what this first object proportioning was brought Can interference be tolerated, this proportioning interference information represents the proportioning combination of this this community and the adjacent area of this this community The disturbed condition of corresponding minizone；

S130, Ruo Gaizhe community is switched to the interference that this first object proportioning brings and can tolerate, then should This community is switched to this first object proportioning.

When the current proportioning of community can not be well matched with up-downgoing portfolio when, carry out proportioning switching Current up-downgoing proportioning is made to match with current traffic, it is possible to make the capacity of community obtain gain, carry The performance of high system.But, minizone different ratio can bring the interference of minizone, affect this community and The business of adjacent area.In embodiments of the present invention, in order to promote the performance of system, base station is determining this community When needing to be switched to first object proportioning, disturb information according to proportioning, determine this this community be switched to this Can the interference that one target proportioning is brought be tolerated, wherein, this proportioning interference information represents this this community and is somebody's turn to do The disturbed condition of the minizone that the proportioning combination of the adjacent area of this community is corresponding, Ruo Gaizhe community be switched to this The interference that one target proportioning is brought can be tolerated, Ze Jianggaizhe community is switched to this first object proportioning.This Sample, when the interference determining that target proportioning is brought can be tolerated, carries out proportioning switching, it is possible to dry in consideration While disturbing, farthest promote the performance of system.

Therefore, the method for the up-downgoing proportioning switching of the embodiment of the present invention, disturb information according to proportioning, Determine that this community is switched to the interference that target proportioning brings when can tolerate, this this community is switched to this mesh Standard configuration ratio, can improve the flexible ratio of subframe, and dynamically adapting portfolio changes such that it is able to promote Systematic function.

The embodiment of the present invention can apply to the communication system of various time division way.Such as, the nothing in LTE Line return system, but this is not limited by the embodiment of the present invention.Should be understood that when applying in wireless backhaul system Time in system, base station refers to that BeNB, UE refer to BUE, say, that the base station bag in the embodiment of the present invention Include BeNB, UE and include BUE.

Should also be understood that in embodiments of the present invention, first object proportioning represents the target proportioning of this community, Second target proportioning represents that the target proportioning of adjacent area, term " first " and " second " are only used to district Divide different contents, the embodiment of the present invention should not constituted any restriction.

In S110, base station determines that this community needs to be switched to first object proportioning.

Specifically, base station decides whether to need to switch proportioning according to the up-downgoing portfolio of this community.Example As, base station can be in the way of taking periodically to adjudicate, and the proportioning switch decision cycle should be according to traffic fluctuations week Phase selects.Base station periodically records the up-downgoing flow in each moment, when the judgement cycle reaches, Being weighted averagely by all record values in measurement period, whether the up-downgoing flow proportional of inspection statistics No longer mate with current proportioning, determine that when not mating these community needs are switched to target from current proportioning and join Ratio.

In S120, information is disturbed according to proportioning in base station, determines that this this community is switched to this first object Can the interference that proportioning is brought be tolerated, this proportioning interference information represents the adjacent area of this this community and this this community The disturbed condition of minizone corresponding to proportioning combination.

When determining that this community needs to be switched to first object proportioning, base station inquiry proportioning interference information, root Disturb information according to proportioning, determine that can this this community be switched to the interference that this first object proportioning brings and hold Bear.

In embodiments of the present invention, proportioning interference information represents the joining of adjacent area of this this this community of community and this The disturbed condition of the minizone more corresponding than combination.Such as, proportioning interference information can be as shown in table 1 Interference-tolerant table.In Table 1, community 1 and community 2 are adjacent area, between each proportioning combination respective cell not Same disturbed condition.The embodiment of the present invention does not limit the representation of proportioning interference information, such as, joins Can also be the representation of non-form than interference information, or, the minizone that the combination of each proportioning is corresponding Disturbed condition can also represent by the size of interference.

Table 1

Information is disturbed according to proportioning in base station, determines the group of the target proportioning of this community and the current proportioning of adjacent area Closing the disturbed condition of corresponding minizone, can i.e. determine that this community is switched to interference that target proportioning brings Tolerance, to determine whether to carry out proportioning switching.Such as, if proportioning interference information is as shown in table 1 doing Disturb tolerance table, then " can't stand " in table represents that corresponding proportioning combines the interference brought for not holding Bearing, " can tolerate " or " noiseless " then represent can be tolerated.If disturbed condition is used in proportioning interference information The size of interference represents, then when the interference that proportioning combination is corresponding exceedes pre-determined threshold for can't stand, no For tolerating when exceeding pre-determined threshold.

In S130, Ruo Gaizhe community is switched to the interference that this first object proportioning brings and can tolerate, Then this this community is switched to this first object proportioning by base station.

Determine this community be switched to the interference that first object proportioning brings can tolerate time, such as, pass through Inquiry table 1 determines the minizone that the first object proportioning of this community is corresponding with the combination of the current proportioning of adjacent area Disturbed condition when being " can tolerate " or " noiseless ", this community is switched to first object and joins by base station Ratio.Such as, base station issue radio resource control (Radio Resource Control, referred to as " RRC ") signaling or by SIB(system message) information, the target proportioning number of notice UE switching With switching time, it is ensured that synchronism switching.So, the embodiment of the present invention disturbs information according to proportioning, really Ding Zhe community is switched to the interference that target proportioning brings when can tolerate, this this community is switched to this target Proportioning, it is not necessary to carry out Signalling exchange with adjacent area, saves system signaling expense, it is ensured that the reality of switching Shi Xing, thus improve systematic function.

In embodiments of the present invention, as in figure 2 it is shown, alternatively, the method 100 also includes:

S140, Ruo Gaizhe community is switched to the interference that this first object proportioning brings and can't stand, then to this The base station of adjacent area sends the request message being jointly switched to this first object proportioning；Receive the base station of this adjacent area Can the expression that send be switched to the response message of this first object proportioning jointly；If this adjacent area can be cut jointly Changing to this first object proportioning, Ze Jianggaizhe community and this adjacent area are switched to this first object proportioning jointly.

Being switched to the interference that this first object proportioning brings in this community when can tolerate, directly should in base station This community is switched to this first object proportioning；It is dry that Er Zhe community is switched to that this first object proportioning brings Disturbing when can't stand, base station can be switched to this first object proportioning jointly to the base station requests of adjacent area.Tool For body, base station sends the first object proportioning of this community, base station of signaled adjacent area by X2 mouth, Common proportioning is asked to switch；Whether the community, detection place, base station of adjacent area is in RB constrained state, if place In RB constrained state, then return response message and represent and can not switch, if to be not on RB limited in adjacent area State, then detect whether this first object proportioning affects the QoS satisfaction rate of community, place, if impact, Return response message to represent and can not switch, if do not affected, then return response message and represent and can jointly cut Change to this first object proportioning, and carry switching time；Then, the base station of this community and the base station of adjacent area This community and adjacent area are switched to this first object proportioning simultaneously.

Therefore, the method for the up-downgoing proportioning switching of the embodiment of the present invention, disturb information according to proportioning, Determine that this community is switched to the interference that target proportioning brings when can't stand, be jointly switched to this mesh with adjacent area Standard configuration ratio, it is possible to increase whole system performance.

Should be understood that in embodiments of the present invention, determining that this community is switched to the interference that target proportioning is brought When can't stand, it would however also be possible to employ the mode not switched, this mode also should contain the protection in the present invention Within the scope of.

In embodiments of the present invention, proportioning interference information can pre-build, is i.e. opening the station initial stage, each base Stand and proportioning interference information is carried out initial work.Therefore, as it is shown on figure 3, alternatively, the method 100 Also include:

S150, the disturbed condition of minizone when traveling through various proportioning according to this this community with this adjacent area, set up This proportioning interference information.

Initialized time, this community travels through various proportionings with adjacent area, measures every kind of proportioning combination correspondence The disturbed condition of minizone, set up proportioning interference information according to this.Alternatively, S150 includes:

For every kind of proportioning combination of this this community with this adjacent area, when up, receive the user of this this community The cycle tests that equipment UE sends on sub-frame of uplink is to determine that can this adjacent area to the interference of this this community Tolerance, sends cycle tests so that this UE determines this neighbour to this UE when descending on descending sub frame Can the interference of this this community be tolerated by district；

If the interference of this this community can be tolerated by this adjacent area, Qie Gaizhe community can to the interference of this adjacent area Tolerance, then arrange the interference of this every kind minizone corresponding to proportioning combination for tolerating；

If the interference of this this community be can't stand by this adjacent area, or this this community is to the interference of this adjacent area not Can tolerate, then the interference of this every kind minizone corresponding to proportioning combination is set for can't stand.

Specifically, when setting up proportioning interference information, interference is measured by sending cycle tests.Ying Li Solving, in embodiments of the present invention, cycle tests includes cycle tests or pilot frequency information, for sake of simplicity, with It is described as a example by cycle tests.Initialized time, this community and adjacent area travel through various difference respectively The proportioning of type, then sends specific cycle tests in the subframe in difference transmission direction, and receiving terminal leads to Whether the measurement crossing the cycle tests to priori can be tolerated to the proportioning determining this type.Judgment basis Parameter be not limited to Signal to Interference plus Noise Ratio (Signal to Interference plus Noise Ratio, Referred to as " SINR "), Reference Signal Received Power (Reference Signal Receiving Power, letter Be referred to as " RSRP "), performance number, Block Error Rate (Block Error Ratio, referred to as " BLER ") etc., The business of each community, QoS etc. are not affected with proportioning for tolerance benchmark after switching.For every kind of proportioning combination, Only when each community experienced interference can be tolerated, the interference of the minizone that the combination of this proportioning is corresponding Just can be configured to tolerance, if having community experienced interference for can't stand, then the combination of this proportioning is set The interference of corresponding minizone is for can't stand.

Such as, in the system shown in Fig. 4, cell initial when, DSUUD is selected in community 1 After proportioning, tell that community 2 uses proportioning (DSUDD) alternately, at the 4th son by X2 message breath On frame, community 1 is up, and community 2 is descending.BUE1 and BeNB2 sends specific and different Cycle tests.BeNB1 is come by the performance number/SINR value receiving cycle tests in different directions subframe Judging whether disturbed one has intolerable impact to community 1, BUE2 detects dry by the way of same Disturb 2 impacts on community 2, and send result to BeNB2, cease finally by X2 message Judge that can the interference that the combination of this proportioning brings be tolerated eventually.So travel through various different joining Ratio, is finally completed the initial work to proportioning interference information.

Therefore, the method for the up-downgoing proportioning switching of the embodiment of the present invention, by setting up proportioning interference information, And carry out proportioning switching according to proportioning interference information, the flexible ratio of subframe, dynamically adapting can be improved Portfolio changes such that it is able to promote systematic function.

Should be understood that in embodiments of the present invention, adjacent area can have multiple, when adjacent area has multiple, and proportioning Interference information can combine corresponding interference-tolerant with the proportioning that each adjacent area is set up respectively in Shi Zhe community Table, it is also possible to total interference-tolerant that Shi Zhe community is corresponding with the proportioning combination that one piece, all adjacent areas are set up Table, as long as You Yige community experienced interference can't stand, then final result is for can't stand.

In embodiments of the present invention, as it is shown in figure 5, alternatively, the method 100 also includes:

S160, when the update cycle arrives, updates this proportioning interference information.

In order to ensure the real-time of proportioning interference information, can dynamically update this proportioning interference information.Optional Ground, S160 includes:

For every kind of proportioning combination of this this community with this adjacent area, when up, receive the UE of this this community The cycle tests sent on the previous of up MBSFN sub-frame or two symbols is to determine this adjacent area pair Can the interference of this this community be tolerated, at the previous of descending MBSFN sub-frame or two symbols when descending Cycle tests is sent to this UE so that this UE determines that can this adjacent area to the interference of this this community on number Tolerance；

If the interference of this this community can be tolerated by this adjacent area, Qie Gaizhe community can to the interference of this adjacent area Tolerance, then be updated to tolerate by the interference of the minizone of this every kind proportioning combination correspondence；

If the interference of this this community be can't stand by this adjacent area, or this this community is to the interference of this adjacent area not Can tolerate, then be updated to can't stand by the interference of the minizone of this every kind proportioning combination correspondence.

Specifically, in order to not interrupt current business, when the update cycle arrives, by by sub-frame configuration For MBSFN sub-frame, and before MBSFN sub-frame, on 1 or 2 symbol, send cycle tests, Then with initializing the measurement that flow process equally carries out traveling through, proportioning interference information is so refreshed.Do so It is advantageous in that and will not interrupt current business, and the least to service impact.

The cycle dynamically updating proportioning interference information should adjust dynamically according to real time business.Such as, For wireless backhaul scene, owing to BeNB Yu BUE is all in a relatively fixed position, therefore The fluctuation of interference is brought mainly due to the Doppler frequency shift of surrounding, it should not too large, dynamically The cycle adjusted should be long, and so impact on system is smaller.

Therefore, the method for the up-downgoing proportioning switching of the embodiment of the present invention, by updating proportioning interference information, Ensure that the real-time of proportioning interference information, thus carry out proportioning switching according to this proportioning interference information, Can improve the flexible ratio of subframe, dynamically adapting portfolio changes, and promotes systematic function.

Should be understood that the mode setting up or updating proportioning interference information can also have alternate manner, such as, join Can not set up when opening station than interference information, but in normal work, record after the switching of each proportioning The interference brought, adds in proportioning interference information, and as the reference frame of follow-up switching, the present invention This is not limited by embodiment.

In embodiments of the present invention, as shown in Figure 6, alternatively, the method 100 also includes:

S170, receives the request message being jointly switched to the second target proportioning that the base station of this adjacent area sends； Ruo Gaizhe community is not on Resource Block RB constrained state, and this second target proportioning not affect this little The service quality QoS satisfaction rate in district, then to this adjacent area base station send expression can jointly be switched to this second The response message of target proportioning；This this community and this adjacent area are switched to this second target proportioning jointly.

Specifically, because the adjacent area each other, adjacent area of this community and this community, this community adjacent area according to When proportioning interference information determines that being switched to the interference that this second target proportioning brings can't stand, this adjacent area Base station can be switched to this second target proportioning jointly to the base station requests of this this community.The base station of this adjacent area Sent this second target proportioning of base station of this this community of signaled by X2 mouth, ask common proportioning to be cut Change；The base station of this this community detects whether this this community is in RB constrained state, if it is limited to be in RB State, then return response message and represent and can not switch, if being not on RB constrained state, then detection should Whether the second target proportioning affects the QoS satisfaction rate of this this community, if impact, returns response message table Show and can not switch, if do not affected, then return response message and represent and can jointly be switched to this second target Proportioning, and carry switching time；Then, the base station of this this community and the base station of this adjacent area are simultaneously by this Community and this adjacent area are switched to this second target proportioning.

Therefore, the method for the up-downgoing proportioning switching of the embodiment of the present invention, by being jointly switched to adjacent area Target proportioning, it is possible to increase whole system performance.

The embodiment of the present invention is described in detail below in conjunction with specific example.It should be noted that these examples are simply In order to help those skilled in the art to be more fully understood that the embodiment of the present invention, and the unrestricted embodiment of the present invention Scope.

As a example by the wireless backhaul system shown in Fig. 4, as shown in table 2, first choose subframe #0, #1, #2, #5, #6, #7 are fixed as the configuration mode of DSUDSU, thus avoid doing between crucial channel Disturb, choose four kinds of proportionings in table and be respectively 0,1,2 and 6 selected as proportioning pond, numbering.

Table 2

#3, #4, #8, #9 subframe is set up proportioning interference information (interference-tolerant table), and interference is held Bear table and periodically safeguard refreshing, it is ensured that its certain real-time.

Assume that community 1 uses proportioning 0, community 2 to use proportioning 2, then in #3, #4, #8, #9 subframe Upper existence is disturbed: BeNB1 is disturbed (disturbed one) by from BeNB2；BUE2 is come from The interference (interference 2) of BUE1, in general BUE is owing to using beam antenna, transmitting power to compare During little, the network planning spacing of BUE will not be the nearest etc. factor, this interference can be ignored.Therefore Here illustrate with disturbed one for main interference emphatically.

1) SINR value on subframe #3, #4, #8, #9 when BeNB1 records identical proportioning.

2) community 1 uses proportioning 0, community 2 to use proportioning 2, and BeNB2 is at #3, #4, #8, #9 The metrical information (pilot frequency information or cycle tests) that upper transmission is identical.

3) BeNB1 receive on #3, #4, #8, #9 metrical information and with SINR when not changing proportioning Value (i.e. the value of step 1 record) compares.

4) when having any one subframe interference difference in subframe higher than thresholding, the most this proportioning can not be held Bear, end value is write interference-tolerant table.As shown in table 3.

Table 3

5) so various proportioning has been traveled through.

6) if adjacent area has multiple, can refer to mode as shown in table 4 and table is extended, to finally sentencing Certainly result uses the form taking common factor, as long as there being an adjacent area to represent that interference can't stand, then final result For can't stand.

Table 4

If if interference 2 can not be left in the basket, setting up interference-tolerant table in the following manner.

4) when having any one subframe interference difference in subframe higher than thresholding, the most this proportioning can not be held Bear, end value is write interferometry tolerance table.

5) so various proportioning has been traveled through.

6) SINR value on subframe #3, #4, #8, #9 when BUE2 records identical proportioning.

7) community 1 uses proportioning 0, community 2 to use proportioning 2, and BUE1 is on #3, #4, #8, #9 Send identical metrical information (pilot frequency information or cycle tests).

8) BUE2 receive on #3, #4, #8, #9 metrical information and with SINR when not changing proportioning Value (i.e. the value of step 6 record) compares

9) when having any one subframe interference difference in subframe higher than thresholding, the most this proportioning can not be held Bear, send result to BeNB2, then be sent to BeNB1 by X2 mouth.

10) BeNB1 and BeNB2 takes common factor to the result of disturbed one and interference 2, whether draws proportioning Can be tolerated, write interference-tolerant table.As long as if disturbed one and interference 2 have an interference can't stand, Then result is for can't stand.

11) if adjacent area is many, with reference to mode as shown in table 4, table is extended, to terminal decision result Using the form taking common factor, as long as there being an adjacent area to represent that interference can't stand, then final result is can not Tolerance.

When returning community and arriving in normal work and interference-tolerant table refresh cycle, by target is joined It is MBSFN sub-frame than sub-frame configuration, and will send on before MBSFN sub-frame 1 or 2 symbol Cycle tests, then with initializing the measurement that flow process equally carries out traveling through, so refreshes interference-tolerant table. This have the advantage that and will not interrupt current business, and the least to service impact.

Follow-up all using this interference-tolerant table as the judgement standard that can switch over proportioning.With proportioning 0,1, 2 and 6, as proportioning pond, decide whether to need to switch proportioning according to the up-downgoing portfolio of this community.Join Should select according to the traffic fluctuations cycle than the switch decision cycle.Such as, BeNB can periodically remember Record the up-downgoing flow in this moment, when the judgement cycle reaches, all record values in measurement period are entered Row weighted average, then inquires about and adjudicates switching table (as shown in table 5), checks statistic flow ratio Whether no longer mate with current proportioning, determine whether to need to switch proportioning.

Table 5

UL:DL	>=3/2	3/2~1	1~2/3	<=2/3
					Proportioning	0	6	1	2

When BeNB1 determine need proportioning to switch time, directly whether self interference-tolerant table of inquiry, see Can switching.

1) if can switch, issue RRC signaling or by SIB information, notice BUE switching is joined Colon and switching time, it is ensured that synchronism switching.

2) if can not switch, send signaling by X2 mouth and report to its target proportioning of adjacent area.

(1) BeNB2 is already at RB constrained state, then return response message by X2 mouth and cancel Switching；

(2) BeNB2 is in non-RB constrained state, then check whether target proportioning affects this community QoS satisfaction rate, if do not affected, then returns a response message, and expression can be common with BeNB1 Being switched to target proportioning, and carry switching time, BeNB1 and BeNB2 was carried out in switching time simultaneously Switching.
