Background technology
Row packet at high speeds is accessed in (High Speed Downlink Packet Access, HSDPA) technology, base
Stand in a Transmission Time Interval (Transmission Time Interval, TTI), believed by down high speed Compliance control
Road (HS-SCCH, High speed shared control channel) to UE sends signaling information, and the signaling information can be with
The data block size of the UE, modulation scheme of employing etc. are identified, are sent to including user equipment (UE), and by high-speed physical
DSCH Downlink Shared Channel (High-Speed Physical Downlink Shared Channel, HS-PDSCH) to UE sends institute
State data block.UE scouts the UE marks that the HS-SCCH sends in each TTI, corresponding in the TTI in order to judge
The data block sent on HS-PDSCH whether to one's name, if it is, starting to receive the data sent on the HS-PDSCH
Block, if it is not, then not responding.
Afterwards, if UE has been properly received the data block, by uplink high-speed special physical control channel (Uplink
High speed dedicated physical control channel, HS-DPCCH) feeding back ACK to base station, in order to base
Continuation of standing sends next data block, if UE receives the data block and have failed, NACK is fed back to base by HS-DPCCH
Stand, in order to base station the data block is resend.UE can also be measured to the channel quality of HS-PDSCH, obtain channel
Quality indicates (Channel Quality Indicator, CQI), and the CQI is reported into base station by HS-DPCCH.
If UE is from current Serving cell to another cell movement, when moving to the intersection region of the two cells,
UE quite now may will not trigger the switching of Serving cell from the downlink signal quality that above-mentioned two cell is received.
However, now UE but may be more far short of what is expected than non-service cell to the uplink receiving signal to noise ratio of Serving cell, for example
Serving cell 6dB more than bigger than the pilot transmission power of non-service cell, or non-service cell is than the reception day of Serving cell
3 more than line number (such as Serving cell is 1 strip antenna, and non-service cell is 4 strip antennas), or the upstream broadband of Serving cell connects
General power (Received Total Wideband Power, RTWP) 6dB higher than non-service cell is received with first-class scene.Now

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
The embodiment of the present invention provides a kind of changing method, if UE is moved from current Serving cell to Target cell, moves
When moving the intersection region of the two cells, UE is suitable that is, descending from the downlink signal quality that above-mentioned two cell is received
The channel quality of channel is relatively good, but the channel quality of Serving cell up channel it is poor when, it is possible to achieve by the clothes of UE
Business cell is switched to Target cell, and the up channel of the Target cell and the channel quality of down channel are preferable, can meet
The communication requirement of UE.
As shown in figure 1, a kind of changing method is discussed in detail, the executive agent of the method is radio network controller (Radio
Network Controller, RNC), the method includes：
101st, RNC obtain user equipment (UE) Serving cell in uplink high-speed special physical control channel HS-DPCCH letter
Road quality specifying information.
This step can be realized using following several ways：
Mode one, RNC is obtained by receiving the missing inspection probability of the correct response ACK/ negative response NACK that base station sends
The channel quality description information of HS-DPCCH in the Serving cell of the UE.
Wherein, the missing inspection probability of the ACK/NACK be the base station in preset time period from the HS-DPCCH not
The number and the base station for receiving ACK/NACK passes through downlink high-speed shared control channel HS- in the preset time period
SCCH sends the ratio of the number of times of schedule information to UE, and the schedule information is to notify the UE in Preset Transfer time interval
TTI sends data block by high-speed physical downlink shared channel (HS-PDSCH) HS-PDSCH to the UE.
For example, base station can send schedule information by HS-SCCH in preset time period to UE, if UE is in the tune
Data block is properly received from HS-PDSCH in the default TTI that degree information is indicated, then can pass through HS- in the default TTI
DPCCH to base station sends ACK, if having failed from HS-PDSCH receiving data blocks in the default TTI, described default
NACK can be sent to base station by HS-DPCCH in TTI.
Base station can count in the preset time period from the HS-DPCCH receive ACK/NACK number and
Send the number of times of schedule information in the preset time period to UE by HS-SCCH, wherein, pass through in the preset time period
HS-SCCH sends the number of times of schedule information and receives ACK/NACK from the HS-DPCCH in the preset time period to UE
Number difference be do not receive the number of ACK/NACK from the HS-DPCCH in the preset time period.
Afterwards, base station calculates the missing inspection probability of the ACK/NACK, it is possible to periodically by the ACK/NACK's
Missing inspection probability is sent to the RNC.
Mode two, RNC is obtained by receiving the unreliable probability of the channel quality indicator (CQI) of the HS-DPCCH that base station sends
The channel quality description information of HS-DPCCH in the Serving cell of the UE.
Wherein, the calculating process of the unreliable probability of the CQI of the HS-DPCCH is：Base station every some cycles (for example
2ms or 4ms) channel quality measurement can be carried out to HS-DPCCH, the CQI value of HS-DPCCH is obtained, and using decoding marking
Technology judges whether the CQI value of the HS-DPCCH is reliable.
Afterwards, CQI reliabilities judged result is insecure number of times during the base station counts multiple cycles, and the CQI can
The CQI of the HS-DPCCH is by the ratio that property judged result is the total degree that insecure number of times judges with CQI reliabilities
Unreliable probability.
The unreliable probability of the CQI of the HS-DPCCH periodically can be sent to base station by the base station.
Mode three, RNC meets described the by receiving the channel quality for directly representing the HS-DPCCH that base station sends
One pre-conditioned channel quality description information.
For example, base station calculates first the missing inspection probability of ACK/NACK, and circular is referring in aforesaid way one
Description.Afterwards, whether the base station judges the missing inspection probability of the ACK/NACK more than the first pre-determined threshold, if described
When the missing inspection probability of ACK/NACK is more than the first pre-determined threshold, illustrate that the channel quality of the HS-DPCCH meets first and presets
Condition (that is, channel quality is poor), then base station is to the RNC transmissions channel quality description information.
Or, and for example, base station calculates first the unreliable probability of the CQI of HS-DPCCH, and circular is referring to above-mentioned
Description in mode two.Afterwards, whether the base station judges the unreliable probability of the CQI of HS-DPCCH more than the second pre- gating
Limit, if the unreliable probability of the CQI of the HS-DPCCH is more than the second pre-determined threshold, illustrates the channel of the HS-DPCCH
Quality meets first pre-conditioned (that is, channel quality is poor), then base station sends the channel quality description information to RNC.
It should be noted that the span of first pre-determined threshold and the second pre-determined threshold for example can be 20%-
80%.If it is too small that first pre-determined threshold or the second pre-determined threshold are arranged, base station is may result in continually to RNC
The channel quality description information is sent, the waste of channel resource is easily caused, services little while will also result in RNC and easily trigger
Area changes, and more Serving cell changes more likely cause signaling call drop, and Serving cell change earlier may be because of non-clothes
Business cell downlink quality it is not good enough and cause HSDPA throughputs decline.If first pre-determined threshold or the second pre- gating
It is excessive that limit is arranged, then may result in that judgement of the base station to the channel quality of HS-DPCCH is more blunt, and more late service is little
Change the problem that HSDPA throughputs degradation can be caused even to break off the base (i.e. throughput is zero) in area.Thus, during practical application,
The concrete value of first pre-determined threshold or the second pre-determined threshold needs rationally to solve above-mentioned two problems.
102nd, the RNC is according to the channel quality satisfaction that the channel quality description information determines the HS-DPCCH
First is pre-conditioned.
Wherein, when step 101 employing mode a period of time, this step specifically performs as follows：Judge the missing inspection of the ACK/NACK
Survey whether probability is more than the first pre-determined threshold, when the missing inspection probability of the ACK/NACK is more than the first pre-determined threshold, it is determined that
The channel quality of the HS-DPCCH meets described first pre-conditioned (that is, channel quality is poor).
When step 101 employing mode two, this step specifically performs as follows：Whether judge the unreliable probability of the CQI
More than the second pre-determined threshold, when the unreliable probability of the CQI of the HS-DPCCH is more than the second pre-determined threshold, it is determined that described
The channel quality of HS-DPCCH meets described first pre-conditioned (that is, channel quality is poor).
When step 101 employing mode three, this step directly can determine institute according to the channel quality description information
The channel quality for stating HS-DPCCH meets described first pre-conditioned (that is, channel quality is poor).
103rd, the Serving cell of the UE is switched to Target cell by the RNC, the HS-DPCCH's of the Target cell
Channel quality and down channel meet the second pre-conditioned, i.e., channel quality and descending letter of the HS-DPCCH of described Target cell
The channel quality in road can meet the communication requirement of UE.
Wherein, in HSDPA technologies, up channel is HS-DPCCH, and down channel includes HS-SCCH and HS-PDSCH.
The process of the RNC selection targets cell is as follows：
On down channel direction, RNC can be on unit power spectral density in total reception bandwidth of UE transmission cells
Chip-level receives energy (Received energy per chip divided by the power density in the
Band, Ec/N0) (or received signal code power (Received Signal Code Power, RSCP)) measurement configured information,
UE receives the Ec/N0 (or RSCP) and measures configured information, proceeds by Ec/N0 (or RSCP) measurements of cell, and will
The measured value of the Ec/N0 (or RSCP) of each cell that measurement is obtained is sent to RNC by base station.It is little that RNC receives each
After the measured value of the Ec/N0 (or RSCP) in area, whether compare the measured value of each cell Ec/N0 (or RSCP) more than the 3rd
Thresholding, if the measured value of Ec/N0 (or RSCP) is more than the 3rd thresholding, illustrates the HS-SCCH and HS-PDSCH in the cell
(down channel) quality is fine.
On up channel direction, base station can carry out cell signal and disturb than (Signal to Interference
Ratio, SIR) measurement, if the cell sir measurement value for obtaining is differed less than four pre-determined thresholds with default sir target value
(such as -3dB), to RNC SIR error events F reports A (SIR error EVENT F Report A) is sent, otherwise, if
When the cell sir measurement value for arriving is differed not less than four pre-determined thresholds with default sir target value, base station to RNC sends SIR mistakes
Event F report B (SIR error EVENT F Report B).Base station to RNC sends SIR error EVENT F Report
B illustrates the DPCCH up channels of the cell very well, therefore the channel quality of HS-DPCCH (up channel) is also fine.
Afterwards, RNC selects the measured value of Ec/N0 (or RSCP) to be more than the 3rd thresholding, and receives SIR from the cell
The cell of error EVENT F Report B is used as Target cell.
In the embodiment of the present invention, RNC can obtain the channel quality description information of HS-DPCCH in the Serving cell of UE, when
According to the channel quality description information determine the channel quality of the HS-DPCCH meet described first it is pre-conditioned when, by institute

Foot second is pre-conditioned, that is, the channel quality of the HS-DPCCH of the Target cell and the channel quality of down channel can be full
The communication requirement of sufficient UE, thus can ensure that the transmission throughput of UE downlink datas.
Particularly there is uplink signal-channel quality unequal leg situation, (i.e. Serving cell uplink signal-channel quality is poor, descending letter
Road quality is preferable) when, for example, when UE is from Serving cell to another cell movement, move to the intersection region of the two cells
When, the channel quality of HS-DPCCH is deteriorated in Serving cell, but the downlink signal quality phase that UE is received from described two cells
