In order to keep technical scheme of the present invention clearer, clear, it is described in further detail below in conjunction with attached drawing.
Specific implementation mode
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The primary solutions of the embodiment of the present invention are：By setting signal threshold value, and cell signal matter is monitored in real time
Amount, when signal quality reaches certain threshold value, scans for peripheral cell, it is possible thereby to by searching in advance, reduce because
It goes to detect again again process and the time of searching net signal without service for a side, or can be to avoid because postponing search, and causes
Unnecessarily search for and waste of resource；In addition, network side can also avoid list according to different business and the comprehensive judgement switching of load
The deficiency of one switchover policy measures, switches according to the actual conditions of operator, optimizes switching mode, promotes the user of terminal
Experience.
Since in the prior art, network cell switching is more passive, it is typically due to side's lossing signal and just initiates switching, this
Kind of method is bigger for the result dependence of network measure, it is likely that and exist and does not timely update or of short duration delay, to
It cannot be switched fast, ensure communication quality.On the other hand, after the switchover policy of a network determines, only it is satisfied with the net
The demand of network operator, and as operator constantly develops, and the intensification cooperated with each other, single strategy cannot expire
The demand of sufficient operator, and the cost for optimizing network is big, risk is high, therefore seeks quick switchover policy from end side to meet
Growing operator needs are significant.
The present invention provides a solution, can be reduced by searching in advance because a side goes to examine again again without service
It surveys process and the time for searching net signal, or can be searched for avoid because postponing, and cause unnecessarily to search for and waste of resource；
In addition, network side can also avoid the deficiency of single switchover policy, according to fortune according to different business and the comprehensive judgement switching of load
The actual conditions of quotient are sought to measure, switch, optimizes switching mode, promotes the user experience of terminal.
The present embodiment considers a kind of scene：The network of A operators, the network switching strategy of A operators are rented by B operators
It is provided by its network characteristic, but B operators want to as possible switch when the network signal of A operators is slightly poor
Network to B operators is gone, and uses the network of oneself, cost slightly lower in this way.If but A operators meet B operations
The requirement of quotient, it is necessary to optimize network, such cost is big, and risk is also high.For B operators, terminal user then can body
Test bad, because when the network signal of A operators is poor, the network of B operators can not be switched to, or A networks
Through no service, but since signal update is delayed, causes in time not switch, affect communication quality.
Therefore, if terminal can control cell switching by way of itself, without the network side that places one's entire reliance upon,
It so could preferably serve operator.
The embodiment of the present invention is elaborated as follows：
Specifically, as shown in Figure 1, first embodiment of the invention proposes a kind of method of control cell switching, including：
Step S101, end side monitor current cell signal, obtain end side current cell signal quality；
The present embodiment terminal refers mainly to mobile terminal user's equipment, i.e. UE.
Effectively switch in minizone to control mobile terminal, first, cell signal is monitored in real time in end side, to obtain
End side current cell signal quality.
Specifically, end side monitors current cell signal by physical layer；Judge that current cell signal is surveyed compared to last
Whether the variation of the cell signal of amount is greater than or equal to preset signals threshold value, if so, being reported from physical layer to upper layer current small
Area's signal quality.
The present embodiment is previously provided with a signal threshold value, and physical layer is by by the variation of the signal monitored and signal threshold value
It is compared, when signal intensity arriving signal threshold value, to upper layer active reporting signal quality, so as to reporting for real-time active
Signal quality, to avoid when network side sending measuring control message for inaccuracies such as the delays or signal jitter of signal measurement
Problem.
It is implemented as follows：
As shown in Fig. 2, Fig. 2 is the live signal monitoring flow diagram of UE.
First, network signal is measured inside UE physical layers, by monitoring cell signal in real time, by physical layer reality
When monitor channel quality, and setting signal threshold value delta.
After obtaining measurement result, the step-length of signal intensity is compared, if current demand signal is tied compared to last measure
The changing value of fruit is greater than or equal to delta, then to upper layer report measurement results, if the more last measurement of signal is less than
Delta, then UE is without any processing.
Wherein, signal threshold value delta is in terminal configurableization so that the susceptibility of signal can be controlled in operator
System, to meet requirement of the heterogeneous networks for signal susceptibility.If it is required that accurately reporting signal, it is small that can delta be set
A bit, if less accurate for signal reporting requirement, what can be arranged is bigger.
As signal intensity arriving signal threshold value delta, to upper layer active reporting signal quality Q.So as to active in real time
Report signal quality, to avoid inaccurate for delay or signal jitter of signal measurement etc. when network sending measuring control message
True sex chromosome mosaicism.
Step S102, when the end side current cell signal quality is less than preset signals threshold value, to terminal surrounding
Cell signal measures, and obtains measurement result；
After end side gets current cell signal quality, by end side current cell signal quality and preset signals door
Limit value is compared, and when end side current cell signal quality is less than preset signals threshold value, is initiated to terminal surrounding cell
The measurement of signal, thus, it is possible in network side there are no when sending measuring control message, pre-cooling measures, to avoid because
The service of loss just goes to initiate to switch, and causes switching slow or handover failure；Alternatively, when network side sending measuring control message,
And signal quality Q is when being also greater than signal threshold value, then terminal can not be initiated to measure, to not waste of resource.
Specifically, as previously mentioned, cell switch process includes mainly with the next stage：Measure control->Measurement report->Switching
Judgement->Switching executes.The control stage is being measured, network side informs the parameter that UE is measured by transmission control message.
After being handed down to mono- Measurement Control message of UE by network, UE will be according to Measurement
Measuring control information included in Control message acts to execute corresponding measurement.
Network side issues UE measuring control informations there are two types of mode：One is by system broadcast information, one is pass through
Dedicated logic channel, which is sent, measures control message.It is bigger to the dependence of network measure in this way, if network side indicates UE
The measurement UE of progress is not supported, or measures control configuration not exclusively, then UE is as receiving invalid measurement control message.
And in the embodiment of the present invention, by introducing signal threshold value, in end side, current cell signal quality is less than preset signals thresholding
When value, the measurement to terminal surrounding cell signal is initiated, it can be to avoid the above problem.
For measurement report, since the channel circumstance of terminal is that the moment is changed, and radio resource management function
Realize that for network side, network side is not aware that the current wireless ring of mobile terminal in the parts RRC of network side in control section
How is border, so needing to establish a kind of measurement report mechanism so that terminal can report current channel situation to network side.
As an implementation, the present embodiment signal threshold value can be arranged as required to, and can also be used adaptive
Mode configures.
It should be noted that in the present embodiment, wherein in end side, current cell signal quality is less than preset signals door
When limit value, terminal surrounding cell signal is measured；In end side, current cell signal quality is greater than or equal to preset signals
When threshold value, terminal surrounding cell signal is not measured, even if at this point, network side sending measuring control message.
That is, in network side sending measuring control message or the non-sending measuring control message of network side, if eventually
End side current cell signal quality is greater than or equal to preset signals threshold value, and terminal-pair peripheral cell signal is without measuring.
The present embodiment can measure decision system to execute above-mentioned judging process by independent cell signal.The cell is believed
Number measure decision system terminal local can be set, high in the clouds can also be set to.
Cell signal measures decision system and judges whether to measure peripheral cell for terminal.The threshold value of judgement
Tthreshold can be obtained from adaptive and learning system.When cell signal quality Q is less than thresholding Tthreshold, and network
There are no when sending measuring control message, pre-cooling measures for side, to avoid just going to initiate to switch because of the service of losing, causes to cut
Change slow or handover failure；When network side sending measuring control message, and when signal quality Q is also greater than Tthreshold, then
Terminal can not be initiated to measure, thus not waste of resource.
Step S103 sends measurement report to network side according to the measurement result, is reported according to the measurement by network side
Announcement decides whether to carry out cell switching；
Step S104 executes cell switching after receiving the cell switching command that the network side issues.
End side to terminal surrounding cell signal after measuring to obtain measurement result, according to measurement result to network side
Measurement report is sent, progress cell switching is decided whether according to the measurement report by network side.
Wherein, in order to consider the actual conditions of each carrier network, in the present embodiment, network side decide whether to carry out it is small
When area switches, can according to the strategy of network radio resources management, and combine different business and load it is comprehensive decide whether to carry out it is small
Area switches.
Wherein, decide whether that carrying out cell switching mainly considers in conjunction with different business and load synthesis：
For different business, it is more desirable to be conducive to the switching of business.Such as in speech business, old operator may
It is more desirable to make full use of very perfect GSM network, and new operator may be more desirable to the LTE nets using newest arranging
Network；For data service, operator may be more desirable to utilize WCDMA networks or LTE nets；Switching based on load can then fill
Divide the Internet resources using each network.
Specifically, first, network side judges whether current demand signal coverage condition reaches signal and cover according to the measurement report
Cover the condition of switching；
If current demand signal coverage condition reaches the condition of signal covering switching, cell switching command is issued to end side,
So that the terminal is switched to suitable cell；
If current demand signal coverage condition is not up to the condition of signal covering switching, judge whether terminal is in CS connections；
If the terminal is in CS connections, the switching of WCDMA/LTE to GSM is supported, do not support reversely to switch；
If the terminal is not at CS connections, judge whether terminal is in PS connections；
If the terminal is in PS connections, judge whether cell load overloads；
If cell load does not overload, the switching of GSM to WCDMA/LTE is supported, do not support reversely to switch；
If cell load overloads, the terminal is switched in suitable cell by load balancing.
Its specific cell switch determining flow based on cell switch determining system as shown in figure 3, can be implemented：
Specifically, cell switch determining system not only considers signal coverage condition, in combination with business and loading condition
It makes decisions.The condition switched is covered if it is signal is reached, then UE is switched to suitable cell；If it is not, judging UE
Whether CS connections, i.e. speech business are in.If just carrying out speech business, the switching of WCDMA/LTE to GSM is supported, it is not necessary to
Support reversed switching.Because the covering of GSM signals is fine for the operator for having GSM, it is not necessarily to one just in GSM systems
The call carried out in system, which is switched to by the method for intersystem handover in WCDMA system, to be continued.Gsm system is not necessarily to upgrading in this way,
The Signalling exchange between WCDMA and gsm system can be decreased to avoid frequent pingpang handoff.
If UE is in PS connections, i.e. data service supports GSM to WCDMA/LTE's if cell load does not overload
Switching, it is not necessary to support reversed switching, can guarantee higher data connection in this way.It, will by load balancing if cell overburden
It is switched in suitable cell, utilizes network to greatest extent.
It is switched fast through the above technical solutions, can be realized in increasingly complicated network environment, improves user experience.
This embodiment scheme by setting signal threshold value, and monitors cell signal quality in real time, reaches in signal quality
When certain threshold value, peripheral cell is scanned for, it is possible thereby to by searching in advance, is reduced because a side is without service duplicate removal again
New detection is searched process and the time of net signal, or can be searched for avoid because postponing, and causes unnecessarily to search for and waste
Resource, and realize that terminal quickly carries out cell switching in a network, ensure communication quality, promotes the user experience of terminal；In addition,
Network side can also avoid the deficiency of single switchover policy according to different business and the comprehensive judgement switching of load；Compared to existing skill
Art, the present invention by cell switching control effectively, ensure communication quality, according to the actual conditions of operator come measure,
Switching optimizes switching mode, meets growing operator needs, to promote the user experience of terminal.
As shown in figure 4, second embodiment of the invention proposes a kind of method of control cell switching, based on shown in above-mentioned Fig. 1
First embodiment, this method is in above-mentioned steps S101：Further include before end side monitoring current cell signal：
Step S100 obtains the preset signals threshold value by adaptive and learning system.
Compared to above-described embodiment, this embodiment scheme further includes obtaining preset signals threshold value by adaptive learning algorithm
Scheme.
When specific implementation, it can be implemented by cell switching signal threshold adaptive learning system.
Its specific algorithmic formula can be as follows：
Tk+1=Tk+σ；Wherein：
σ is correction function, and whether its value directly influences algorithm and restrain or convergence rate.For example, switching each time
After success, σ is increased to handoff threshold, before switching, system reaches thresholding maximum value at this time without service.
T is signal threshold value, Tk+1For signal threshold value next time, TkFor current demand signal threshold value, K is positive integer, each
After secondary handover success, T is recorded, is reconciled by correction function, is finally tended towards stability.As shown in figure 5, the system is initial
Value T0 is an empirical value, after initiating handover measurement each time, using current threshold T k as new sample, is sent into study system
System is trained, and the result of gained is signal threshold value next time, is reconciled by correction function, is finally tended towards stability and is reached maximum
Value Tmax.
, can be according to network condition to determine whether switch over measurement in this way, by adaptive approach, and eliminate the reliance on
In network, network burden is reduced.And on the basis of operator cooperates with each other, it is not necessary to be carried out to carrier network large-scale
Optimization reduces expense.
For example, network A rents the network of network B, in network B, the switchover policy that operator uses is that it is made to be not easy
It is switched to other networks up, and as A operators, in order to more use oneself network, reduce expense, it would be desirable to be easier
Be switched to A networks up, can thus measure in advance so that it switches as early as possible, without being constrained by network B.
Its thresholding can prevent ping-pong to greatest extent by automatic adjusument after stablizing.
As an implementation, above-mentioned correction function is σ=α * (- 1)i1/ek；Wherein：
Every time when network issues switching command, i values are even number, and otherwise i values are odd number.α is calibration factor, is defaulted as 1,
For adjusting Step size, K is positive integer, and for adjusting convergence rate, e is the truth of a matter of natural logrithm.
It is measured to peripheral cell, the preset signals threshold value obtained using adaptive learning algorithm
(threshold) when, when cell signal quality Q is less than thresholding threshold, and there are no sending measuring controls to disappear for network side
When breath, pre-cooling measures, and to avoid just going to initiate to switch because of the service of losing, causes switching slow or handover failure；Work as net
When the sending measuring control message of network side, and when signal quality Q is also greater than threshold, then terminal can not be initiated to measure, to
Not waste of resource.Threshold is the process of adaptive learning so that its under certain network can Fast Convergent, avoid rattling
Effect.
For example, network A rents the network of network B, in network B, the switchover policy that operator uses is that it is made to be not easy
It is switched to other networks up, and as A operators, in order to more use oneself network, reduce expense, it would be desirable to be easier

The present embodiment obtains signal threshold value by adaptive algorithm, is less than in the end side current cell signal quality
When preset signals threshold value, terminal surrounding cell signal is measured, measurement result is obtained；According to measurement result to network side
Measurement report is sent, progress cell switching is decided whether according to measurement report by network side；Receive network side issue it is small
After area's switching command, cell switching is executed.This programme monitors cell signal quality in real time by setting signal threshold value,

As shown in figure 8, first embodiment of the invention proposes a kind of terminal of control cell switching, including：Monitoring modular
201, control module 202, report sending module 203 and handover module 204 are measured, wherein：
Monitoring modular 201 obtains end side current cell signal quality for monitoring end side current cell signal；
Control module 202 is measured, is used for when the end side current cell signal quality is less than preset signals threshold value,
Terminal surrounding cell signal is measured, measurement result is obtained；
Report sending module 203, for according to the measurement result to network side send measurement report, by network side according to
The measurement report decides whether to carry out cell switching；
Handover module 204, for after receiving the cell switching command that the network side issues, executing cell switching.
Further, the monitoring modular 201 is additionally operable to monitor current cell signal by physical layer；Work as described in judgement
Whether variation of the preceding cell signal compared to the last cell signal measured is greater than or equal to preset signals threshold value, if so, by
Physical layer reports current cell signal quality to upper layer.
Specifically, the present embodiment terminal is mainly mobile terminal user's equipment, i.e. UE.
Effectively switch in minizone to control mobile terminal, first, cell signal is monitored in real time in end side, to obtain
End side current cell signal quality.
Specifically, end side monitors current cell signal by physical layer；Judge that current cell signal is surveyed compared to last
Whether the variation of the cell signal of amount is greater than or equal to preset signals threshold value, if so, being reported from physical layer to upper layer current small
Area's signal quality.
The present embodiment is previously provided with a signal threshold value, and physical layer is by by the variation of the signal monitored and signal threshold value
It is compared, when signal intensity arriving signal threshold value, to upper layer active reporting signal quality, so as to reporting for real-time active
Signal quality, to avoid when network side sending measuring control message for inaccuracies such as the delays or signal jitter of signal measurement
Problem.
It is implemented as follows：
As shown in Fig. 2, Fig. 2 is the live signal monitoring flow diagram of UE.
First, network signal is measured inside UE physical layers, by monitoring cell signal in real time, by physical layer reality
When monitor channel quality, and setting signal threshold value delta.
After obtaining measurement result, the step-length of signal intensity is compared, if current demand signal is tied compared to last measure
The changing value of fruit is greater than or equal to delta, then to upper layer report measurement results, if the more last measurement of signal is less than
Delta, then UE is without any processing.
Wherein, signal threshold value delta is in terminal configurableization so that the susceptibility of signal can be controlled in operator
System, to meet requirement of the heterogeneous networks for signal susceptibility.If it is required that accurately reporting signal, it is small that can delta be set
A bit, if less accurate for signal reporting requirement, what can be arranged is bigger.
As signal intensity arriving signal threshold value delta, to upper layer active reporting signal quality Q.So as to active in real time
Report signal quality, to avoid inaccurate for delay or signal jitter of signal measurement etc. when network sending measuring control message
True sex chromosome mosaicism.
After end side gets current cell signal quality, by end side current cell signal quality and preset signals door
Limit value is compared, and when end side current cell signal quality is less than preset signals threshold value, is initiated to terminal surrounding cell
The measurement of signal, thus, it is possible in network side there are no when sending measuring control message, pre-cooling measures, to avoid because
The service of loss just goes to initiate to switch, and causes switching slow or handover failure；Alternatively, when network side sending measuring control message,
And signal quality Q is when being also greater than signal threshold value, then terminal can not be initiated to measure, to not waste of resource.
Specifically, as previously mentioned, cell switch process includes mainly with the next stage：Measure control->Measurement report->Switching
Judgement->Switching executes.The control stage is being measured, network side informs the parameter that UE is measured by transmission control message.
After being handed down to mono- Measurement Control message of UE by network, UE will be according to Measurement
Measuring control information included in Control message acts to execute corresponding measurement.
Network side issues UE measuring control informations there are two types of mode：One is by system broadcast information, one is pass through
Dedicated logic channel, which is sent, measures control message.It is bigger to the dependence of network measure in this way, if network side indicates UE
The measurement UE of progress is not supported, or measures control configuration not exclusively, then UE is as receiving invalid measurement control message.
And in the embodiment of the present invention, by introducing signal threshold value, in end side, current cell signal quality is less than preset signals thresholding
When value, the measurement to terminal surrounding cell signal is initiated, it can be to avoid the above problem.
For measurement report, since the channel circumstance of terminal is that the moment is changed, and radio resource management function
Realize that for network side, network side is not aware that the current wireless ring of mobile terminal in the parts RRC of network side in control section
How is border, so needing to establish a kind of measurement report mechanism so that terminal can report current channel situation to network side.
As an implementation, the present embodiment signal threshold value can be arranged as required to, and can also be used adaptive
Mode configures.
It should be noted that in the present embodiment, wherein in end side, current cell signal quality is less than preset signals door
When limit value, terminal surrounding cell signal is measured；In end side, current cell signal quality is greater than or equal to preset signals
When threshold value, terminal surrounding cell signal is not measured, even if at this point, network side sending measuring control message.
That is, in network side sending measuring control message or the non-sending measuring control message of network side, if eventually
End side current cell signal quality is greater than or equal to preset signals threshold value, and terminal-pair peripheral cell signal is without measuring.
The present embodiment can measure decision system to execute above-mentioned judging process by independent cell signal.The cell is believed
Number measure decision system terminal local can be set, high in the clouds can also be set to.
Cell signal measures decision system and judges whether to measure peripheral cell for terminal.The threshold value of judgement
Tthreshold can be obtained from adaptive and learning system.When cell signal quality Q is less than thresholding Tthreshold, and network
There are no when sending measuring control message, pre-cooling measures for side, to avoid just going to initiate to switch because of the service of losing, causes to cut
Change slow or handover failure；When network side sending measuring control message, and when signal quality Q is also greater than Tthreshold, then
Terminal can not be initiated to measure, thus not waste of resource.
End side to terminal surrounding cell signal after measuring to obtain measurement result, according to measurement result to network side
Measurement report is sent, progress cell switching is decided whether according to the measurement report by network side.
Wherein, in order to consider the actual conditions of each carrier network, in the present embodiment, network side decide whether to carry out it is small
When area switches, can according to the strategy of network radio resources management, and combine different business and load it is comprehensive decide whether to carry out it is small
Area switches.
Wherein, decide whether that carrying out cell switching mainly considers in conjunction with different business and load synthesis：
For different business, it is more desirable to be conducive to the switching of business.Such as in speech business, old operator may
It is more desirable to make full use of very perfect GSM network, and new operator may be more desirable to the LTE nets using newest arranging
Network；For data service, operator may be more desirable to utilize WCDMA networks or LTE nets；Switching based on load can then fill
Divide the Internet resources using each network.
Specifically, first, network side judges whether current demand signal coverage condition reaches signal and cover according to the measurement report
Cover the condition of switching；
If current demand signal coverage condition reaches the condition of signal covering switching, cell switching command is issued to end side,
So that the terminal is switched to suitable cell；
If current demand signal coverage condition is not up to the condition of signal covering switching, judge whether terminal is in CS connections；
If the terminal is in CS connections, the switching of WCDMA/LTE to GSM is supported, do not support reversely to switch；
If the terminal is not at CS connections, judge whether terminal is in PS connections；
If the terminal is in PS connections, judge whether cell load overloads；
If cell load does not overload, the switching of GSM to WCDMA/LTE is supported, do not support reversely to switch；
If cell load overloads, the terminal is switched in suitable cell by load balancing.
Its specific cell switch determining flow based on cell switch determining system as shown in figure 3, can be implemented：
Specifically, cell switch determining system not only considers signal coverage condition, in combination with business and loading condition
It makes decisions.The condition switched is covered if it is signal is reached, then UE is switched to suitable cell；If it is not, judging UE
Whether CS connections, i.e. speech business are in.If just carrying out speech business, the switching of WCDMA/LTE to GSM is supported, it is not necessary to
Support reversed switching.Because the covering of GSM signals is fine for the operator for having GSM, it is not necessarily to one just in GSM systems
The call carried out in system, which is switched to by the method for intersystem handover in WCDMA system, to be continued.Gsm system is not necessarily to upgrading in this way,
The Signalling exchange between WCDMA and gsm system can be decreased to avoid frequent pingpang handoff.
If UE is in PS connections, i.e. data service supports GSM to WCDMA/LTE's if cell load does not overload
Switching, it is not necessary to support reversed switching, can guarantee higher data connection in this way.It, will by load balancing if cell overburden
It is switched in suitable cell, utilizes network to greatest extent.
It is switched fast through the above technical solutions, can be realized in increasingly complicated network environment, improves user experience.
This embodiment scheme by setting signal threshold value, and monitors cell signal quality in real time, reaches in signal quality
When certain threshold value, peripheral cell is scanned for, it is possible thereby to by searching in advance, is reduced because a side is without service duplicate removal again
New detection is searched process and the time of net signal, or can be searched for avoid because postponing, and causes unnecessarily to search for and waste
Resource, and realize that terminal quickly carries out cell switching in a network, ensure communication quality, promotes the user experience of terminal；In addition,
Network side can also avoid the deficiency of single switchover policy according to different business and the comprehensive judgement switching of load；Compared to existing skill
Art, the present invention by cell switching control effectively, ensure communication quality, according to the actual conditions of operator come measure,
Switching optimizes switching mode, meets growing operator needs, to promote the user experience of terminal.
As shown in figure 9, second embodiment of the invention proposes that a kind of terminal of control cell switching, the terminal further include：
Adaptive learning modules 200 obtain the preset signals threshold value for passing through adaptive and learning system.
Compared to above-described embodiment, this embodiment scheme further includes obtaining preset signals threshold value by adaptive learning algorithm
Scheme.
When specific implementation, it can be implemented by cell switching signal threshold adaptive learning system.
Its specific algorithmic formula can be as follows：
Tk+1=Tk+σ；Wherein：
σ is correction function, and whether its value directly influences algorithm and restrain or convergence rate.For example, switching each time
After success, σ is increased to handoff threshold, before switching, system reaches thresholding maximum value at this time without service.
T is signal threshold value, Tk+1For signal threshold value next time, TkFor current demand signal threshold value, K is positive integer, each
After secondary handover success, T is recorded, is reconciled by correction function, is finally tended towards stability.As shown in figure 5, the system is initial
Value T0 is an empirical value, after initiating handover measurement each time, by current threshold TkAs new sample, it is sent into study system
System is trained, and the result of gained is signal threshold value next time, is reconciled by correction function, is finally tended towards stability and is reached maximum
Value Tmax.
, can be according to network condition to determine whether switch over measurement in this way, by adaptive approach, and eliminate the reliance on
In network, network burden is reduced.And on the basis of operator cooperates with each other, it is not necessary to be carried out to carrier network large-scale
Optimization reduces expense.
For example, network A rents the network of network B, in network B, the switchover policy that operator uses is that it is made to be not easy
It is switched to other networks up, and as A operators, in order to more use oneself network, reduce expense, it would be desirable to be easier
Be switched to A networks up, can thus measure in advance so that it switches as early as possible, without being constrained by network B.
Its thresholding can prevent ping-pong to greatest extent by automatic adjusument after stablizing.
As an implementation, above-mentioned correction function is σ=α * (- 1)i1/ek；Wherein：
Every time when network issues switching command, i values are even number, and otherwise i values are odd number.α is calibration factor, is defaulted as 1,
For adjusting Step size, K is positive integer, and for adjusting convergence rate, e is the truth of a matter of natural logrithm.
It is measured to peripheral cell, the preset signals threshold value obtained using adaptive learning algorithm
(threshold) when, when cell signal quality Q is less than thresholding threshold, and there are no sending measuring controls to disappear for network side
When breath, pre-cooling measures, and to avoid just going to initiate to switch because of the service of losing, causes switching slow or handover failure；Work as net
When the sending measuring control message of network side, and when signal quality Q is also greater than threshold, then terminal can not be initiated to measure, to
Not waste of resource.Threshold is the process of adaptive learning so that its under certain network can Fast Convergent, avoid rattling
Effect.
For example, network A rents the network of network B, in network B, the switchover policy that operator uses is that it is made to be not easy
It is switched to other networks up, and as A operators, in order to more use oneself network, reduce expense, it would be desirable to be easier
Be switched to A networks up, can thus measure in advance so that it switches as early as possible, without being constrained by network B.
