Described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those skilled in the art obtained under the premise of creative work is not made it is all its
His embodiment, belongs to the scope of protection of the invention.
Embodiment one
As shown in figure 1, the present invention provides a kind of method of re-selecting cell.The reselecting method is main by gravity treatment
System is performed.The gravity treatment system is installed in the terminal.Wherein, the mobile terminal include but not
It is limited to：Mobile phone, wearable electronic etc..The mobile terminal includes multiple communication modules, each communication
Module correspondence accesses a kind of mobile network's type (hereinafter referred to as network type).The communication module include but not
It is limited to：Gsm communication module, LTE communication module, 3G communication modules etc..The mobile terminal is worked as in access
After preceding cell, the detection of timing and the network quality information of current area.
If the cell being currently accessed is GSM cell, the acquisition of mobile terminal timing during idle shape
RSSI (signal intensity instruction).The gravity treatment system according to the comparing of the RSSI and default RSSI thresholdings,
Determine whether re-selecting cell.For example, when the gravity treatment system detectio to RSSI is less than or equal to RSSI thresholdings,
Then determine re-selecting cell；Conversely, then next time be timed to up to when, detect again.The step of the re-selecting cell
It is rapid as described below.
In step sl, the gravity treatment system is worked as and monitors to be down to the network quality information of current cell communication
During gravity treatment thresholding, according to the network that each described network type that can be accessed, acquisition communicate with each neighbor cell
Quality information.
Specifically, the gravity treatment system sends correspondence by each communication module included in the mobile terminal
The network quality test information of network type, after neighbor cell receives the network quality test information, feedback
With network quality information.Then the gravity treatment system obtains the network quality information communicated with each neighbor cell.
The network quality information includes but is not limited to following at least two：RSSI, RSCP (received signal code
Power), RSRP (Reference Signal Received Power).Wherein, the network quality letter that gsm communication module is received
It is RSSI to cease, and the network quality information that 3G communication modules (such as WCDMA) are received is RSCP,
The network quality information that LTE communication module is received is RSRP.
It should be noted that it should be appreciated by those skilled in the art that the mode of above-mentioned acquisition network quality information
It is only for example, occurs new communication module from now on, the gravity treatment system is small with corresponding according to new communication module
The channel sensitive manner in area, obtains corresponding network quality information.
In step s 2, the gravity treatment system according to default each network type prioritization, from each phase
The minimum network type of priority starts in adjacent cell, compare one by one neighbor cell network quality information whether
The pre-determined threshold of map network type is reached, and it is the network class for reaching correspondence thresholding to start comparative result one by one
Gravity treatment timing corresponding to type, until determining gravity treatment timing network type overtime at first.
Here, the priority of the network type is exemplified as from low to high：2G types, 3G types, 4G classes
Type.Wherein, 3G types include：CDMA, WCDMA, TD-CDMA etc..2G types include：
GSM.4G types include：LTE.
It should be noted that it should be appreciated by those skilled in the art that above-mentioned network type is only for example, from now on
The new network type for occurring, can according to actual needs be configured to readjust the priority of each network type.
Here, each gravity treatment duration can be performed by the timer of map network type.Can in each timer
Default different gravity treatment duration.Wherein, the gravity treatment duration corresponding to high-priority network type is not more than low excellent
Gravity treatment duration corresponding to first level network type.In a kind of preferred embodiment, for corresponding to adjacent priority
Two gravity treatment durations for, when gravity treatment duration corresponding to low priority is more than gravity treatment corresponding to high priority
Duration sum that is long and judging network quality information step.
Here, the gravity treatment timing time-out refers to timer startup start and after gravity treatment duration described in timing,
Stop timing because of time-out.
Specifically, after the network quality information that each neighbor cell is fed back is received, the gravity treatment system energy
Enough network types for determining the current each neighbor cell that can be communicated.The gravity treatment system is also individually for every kind of net
Network type sets reselection timer, and each reselection timer can proceed by weight on the opportunity set by gravity treatment system
Select timing.
For example, the prioritization from low to high of the gravity treatment systemic presupposition is：GSM and CDMA.From
The minimum network type of priority starts in each neighbor cell, and the gravity treatment system first compares the phase based on GSM
Whether the network quality information of adjacent cell reaches the thresholding of default GSM；If not up to, continuing to compare base
Whether the network quality in the neighbor cell of CDMA reaches the thresholding of default CDMA.
Then, when the gravity treatment system determines the network quality of the neighbor cell based on CDMA less than default
During the thresholding of CDMA, determine that each neighbor cell is unsuitable for accessing, continue to reside in current area.
And for example, if the gravity treatment system judge based on GSM neighbor cell network quality information reached it is pre-
If GSM thresholding, then first start GSM corresponding to timer T1 start gravity treatment timing, be further continued for
Whether the network quality for comparing the neighbor cell based on CDMA reaches the thresholding of default CDMA.
When the gravity treatment system determines the network quality of the neighbor cell based on CDMA optionally greater than default
During the thresholding of CDMA, start the timer T2 corresponding to CDMA and start gravity treatment timing, and wait two to determine
When device time-out, due to the gravity treatment duration of the gravity treatment duration less than timer T1 of timer T2, therefore under the situation,
Timer T2 will be first overtime, and the gravity treatment system determines network type for CDMA, and performs step S3
In a kind of preferred scheme, the gravity treatment system is described heavy before waiting two timer timing to terminate
System is selected to repeat to obtain the network quality information of each neighbor cell, and since the network type of lowest priority,
Whether the network quality information for comparing neighbor cell one by one reaches the pre-determined threshold of map network type, and one by one
It is the gravity treatment timing corresponding to the network type for not reaching correspondence thresholding to close comparative result.
Still by taking the gravity treatment scheme of above-mentioned CDMA neighbor cells and GSM neighbor cells as an example, if the gravity treatment
System judges that the network quality information based on CDMA and two neighbor cells based on GSM is all consistently higher than
In each self-corresponding thresholding, when being less than the gravity treatment corresponding to GSM due to the gravity treatment duration corresponding to CDMA
It is long, then it is described it is meant that the timer corresponding to CDMA is prior to the timer expiry corresponding to GSM
Gravity treatment system determines that the network type corresponding to timer overtime at first is CDMA, and performs step S3.
If the network quality information of the neighbor cell based on GSM is consistently higher than equal to corresponding thresholding, and is based on
The network quality information of the neighbor cell of CDMA occurs less than correspondence thresholding, it is meant that, corresponding to CDMA
Timer be closed early before the timeout, then the timer corresponding to GSM will at first time-out, it is described
Gravity treatment system determines that the network type corresponding to timer overtime at first is GSM, and performs step S3.
In step s3, according to identified network type, selection accesses identified net to the gravity treatment system
Neighbor cell corresponding to network type.
The gravity treatment system can send access request according to identified network type to corresponding neighbor cell,
Access procedure is performed with the neighbor cell.
Here, it is prior art to perform access procedure with neighbor cell, will not be described in detail herein.
Embodiment two
From unlike embodiment one, in order to backward compatible, the improved complexity of gravity treatment system is reduced.It is described
The timer that duration is fixed in multiple timing is preset in gravity treatment system.A kind of network type of each timer correspondence.
The gravity treatment system performs following steps after execution of step S1.As shown in Figure 2.
In the step s 21, the network type institute that priority is minimum in the gravity treatment systematic comparison neighbor cell is right
The network quality information answered with whether reach corresponding pre-determined threshold；If so, then starting corresponding non-timing
Timer, and perform step S22；If it is not, then performing step S22.
Here, the timer of the non-timing refers to timer not yet timing operation.Now timer may be from
It was not activated or because certain condition has stopped timing.
Here, described refers to that timer has begun to gravity treatment timing under the present conditions just in the timer of timing,
And have not timed out.The closing is just in the mode of the timing of the timer of timing：The gravity treatment system will just
Stopped in the timer of timing.
In step S22, the network type institute of one-level priority high in the gravity treatment systematic comparison neighbor cell
Corresponding network quality information with whether reach corresponding pre-determined threshold；If so, then performing step S23；If it is not,
Step S22 is then repeated, to compare the network quality information of more higher leveled network type neighbor cell.
In step S23, the gravity treatment system starts the non-timing corresponding to current priority network type
Timer, and restart lower than current priority just in each timer of timing.
Here, the gravity treatment system can simultaneously start and restart current priority and each less than current priority
Timer.Preferably, the gravity treatment system first starts the non-timing corresponding to current priority network type
Timer, then restart lower than current priority just in each timer of timing.
Here, it is described restart just refer in each timer of timing：In timer not yet timing time-out period,
Reboot operation is carried out to timer, makes its reclocking.
The gravity treatment system repeats step S22, until having compared all adjacent after step S23 is performed
Cell, and monitor network type at first corresponding to the timer of timing time-out, the network class that will be monitored
Type determines gravity treatment timing network type overtime at first, then performs the step S3 in embodiment one.
It should be noted that it should be appreciated by those skilled in the art that judge each timer whether time-out mode
Can in poll the network quality information of the neighbor cell of all-network type and corresponding thresholding comparison it
Afterwards, concentrate and judge.By the way of high-priority interrupt time-out can also be sent when there is timer because of time-out
During signal, the gravity treatment system interrupts above-mentioned circulation step by force because of the timeout signal, and performs step S3.
It is with the mobile terminal comprising gsm communication module, cdma communication module and LTE communication module
Example, is built-in with the gravity treatment system described in the present embodiment in the mobile terminal.The gravity treatment system monitor with
When the network quality information of current cell communication is less than pre-determined threshold, step S1 is performed, get three kinds of nets
The network quality information of the neighbor cell of network type, and perform each step in the present embodiment.
That is, the priority of described each network type of gravity treatment systemic presupposition is from low to high GSM, CDMA, LTE.
The gravity treatment system first compares the network quality information and default GSM thresholdings of the neighbor cell of GSM；If
Optionally greater than the thresholding, then start the corresponding timer T1 of GSM, and continue primary network station type higher
Corresponding network quality information；If it is not, then continuing the network quality corresponding to primary network station type higher
Information.
Then, the gravity treatment system continue to compare the network quality information of the neighbor cell of CDMA with it is default
CDMA thresholdings；If being optionally greater than the thresholding, first start the corresponding timer T2 of CDMA, then restart
Just in the timer T1 of timing, and continue the network quality information corresponding to primary network station type higher；If
It is no, then continue the network quality information corresponding to primary network station type higher.
Then, the gravity treatment system continues to compare the network quality information of the neighbor cell of LTE and default LTE
Thresholding；If remaining above equal to the thresholding, first start the corresponding timer T3 of LTE, then restart just in timing
Timer T1 and T2.If now judging each timer, when determining timer T3 time-out, embodiment is performed
Step S3 in one；If it is not, three kinds of network quality informations of the neighbor cell of network type are then reacquired,
And re-execute and above-mentioned respectively compare.Until total timing length time-out of default gravity treatment, then continue resident current
Cell；Or, the timer expiry of one of network type, the gravity treatment system is performed in embodiment one
The step of S3.
In a kind of preferred embodiment, the gravity treatment system is interior during any timer expiry is not monitored, weight
The network quality information of each neighbor cell is newly obtained, and performs above-mentioned steps S21-S23.
From unlike above-mentioned example, compare period in the network quality information of each priority, correspondence priority
Timer may timing run.Now, network quality of the gravity treatment system in each neighbor cell
When information is not up to corresponding pre-determined threshold, close corresponding to network type where current neighbor cell
The timing of the timer of timing, makes its no longer timing.When comparative result is optionally greater than correspondence thresholding, institute
State gravity treatment system and do not restart the timer of correspondence priority, but restart the meter lower than current priority
When each timer.
For example, when the gravity treatment system compares the network of each neighbor cell of GSM, CDMA and LTE for the first time
When quality information is with respective corresponding thresholding, timer T1, T2 and T3 are started.In timer T1, T2
During all being had not timed out with T3, the gravity treatment system obtains the network quality information of these three neighbor cells again,
And again perform above steps S21-S23 when, compare the network quality information corresponding to GSM remain above it is right
The thresholding answered, then disregard current timer T1.Continue relatively and determine that the CDMA institutes of newest acquisition are right
The network quality information answered is less than correspondence thresholding, the then timing of Off Timer T2.Continue relatively and determine most
Network quality information corresponding to the new LTE for obtaining is higher than correspondence thresholding, then no longer restart timer T3, but
Restart timer T1.If now judging each timer, timer T3 time-out is determined, the gravity treatment system will
LTE types corresponding to timer T3 and perform step S3 as the network type of gravity treatment.
With reference to shown in Fig. 3, also a kind of preferred scheme is, for the carrying out for preventing the gravity treatment system long
Gravity treatment judges, also includes in the gravity treatment system：The counter of each timer of correspondence.The gravity treatment system exists
Start every time/when restarting timer, indicate counter corresponding with timer to add 1, until that ought have counter institute
When count value reaches default count threshold, timer corresponding with the counter is no longer restarted.In addition, described
Gravity treatment system simultaneously closes off the counting of counter in each Off Timer timing.
For example, when the gravity treatment system compares the network of each neighbor cell of GSM, CDMA and LTE for the first time
When quality information is with respective corresponding thresholding, timer T1, T2 and T3 are started, also corresponding counter D1,
D2 is corresponding with D3 to be counted as 1.During timer T1, T2 and T3 have not timed out, the gravity treatment system
The network quality information of these three neighbor cells is obtained for the second time, and performs above steps S21-S23 again
When, compare the network quality information corresponding to GSM and remain above corresponding thresholding, then disregard current timing
Device T1.Continue relatively and determine that the network quality information corresponding to the CDMA of newest acquisition is less than to answering the door
Limit, the then timing of Off Timer T2 and the counting of counter D2.Continue relatively and determine newest acquisition
Network quality information corresponding to LTE is higher than correspondence thresholding, then no longer restart timer T3, but restart timing
The count value of counter D1 is simultaneously added 1 and obtains count value 2 by device T1.If now still without timer expiry,
The gravity treatment system third time obtains the network quality information of these three neighbor cells, and it is adjacent small to compare GSM
The network quality information in area remains above corresponding thresholding, then disregard current timer T1.Continue to compare simultaneously
Determine that the network quality information corresponding to the CDMA of newest acquisition is less than correspondence thresholding, then continue to compare and true
Network quality information corresponding to the LTE of fixed newest acquisition is higher than correspondence thresholding, then no longer restart timer T3,
And whether the count value 2 of counter D1 is judged beyond default count threshold, if so, then not restart determining
When device D1, otherwise restart timer T1.If now judging each timer, timer T3 time-out, institute are determined
Gravity treatment system is stated using the LTE types corresponding to timer T3 as the network type of gravity treatment, and step is performed
S3。

The network quality information that LTE communication module is received is RSRP.
It should be noted that it should be appreciated by those skilled in the art that the mode of above-mentioned acquisition network quality information
Be only for example, occur new communication module from now on, the gravity treatment starting module 11 according to new communication module with
The channel sensitive manner of respective cell, obtains corresponding network quality information.
The gravity treatment system 1 also includes：Gravity treatment module 12, AM access module 13.
The gravity treatment starting module 11 is used for according to the prioritization of default each network type, from each adjacent
The minimum network type of priority starts in cell, and whether the network quality information for comparing neighbor cell one by one reaches
To the pre-determined threshold of map network type, and it is the network type for reaching correspondence thresholding to start comparative result one by one
Corresponding gravity treatment timing, until determining gravity treatment timing network type overtime at first.
Here, the priority of the network type is exemplified as from low to high：2G types, 3G types, 4G classes
Type.Wherein, 3G types include：CDMA, WCDMA, TD-CDMA etc..2G types include：
GSM.4G types include：LTE.
It should be noted that it should be appreciated by those skilled in the art that above-mentioned network type is only for example, from now on
The new network type for occurring, the gravity treatment module 12 can be configured to readjust each net according to actual needs
The priority of network type.
Here, each gravity treatment duration can be performed by the timer of map network type.Can in each timer
Default different gravity treatment duration.Wherein, the gravity treatment duration corresponding to high-priority network type is not more than low excellent
Gravity treatment duration corresponding to first level network type.In a kind of preferred embodiment, for corresponding to adjacent priority
Two gravity treatment durations for, when gravity treatment duration corresponding to low priority is more than gravity treatment corresponding to high priority
Duration sum that is long and judging network quality information step.
Here, the gravity treatment timing time-out refers to timer startup start and after gravity treatment duration described in timing,
Stop timing because of time-out.
Specifically, after the network quality information that each neighbor cell is fed back is received, the gravity treatment module 12
Can determine the network type of the current each neighbor cell that can be communicated.The gravity treatment module 12 is also individually for often
Plant network type and reselection timer is set, each reselection timer can start on the opportunity set by gravity treatment module 12
Carry out gravity treatment timing.
For example, the default prioritization from low to high of gravity treatment module 12 is：GSM and CDMA.
Since each neighbor cell the minimum network type of priority, the gravity treatment module 12 first compares based on GSM
The network quality information of neighbor cell whether reach the thresholding of default GSM；If not up to, continuing to compare
Whether the network quality of the relatively neighbor cell based on CDMA reaches the thresholding of default CDMA.
Then, when the gravity treatment module 12 determines the network quality of the neighbor cell based on CDMA less than pre-
If CDMA thresholding when, determine each neighbor cell be unsuitable for access, continue to reside in current area.
And for example, if the gravity treatment module 12 judges that the network quality information of the neighbor cell based on GSM reaches
The thresholding of default GSM, then first start the timer T1 corresponding to GSM and start gravity treatment timing, then
Whether the network quality for continuing to compare the neighbor cell based on CDMA reaches the thresholding of default CDMA.
When the gravity treatment module 12 determines the network quality of the neighbor cell based on CDMA optionally greater than default
CDMA thresholding when, start the timer T2 corresponding to CDMA and start gravity treatment timing, and wait two
Timer expiry, due to the gravity treatment duration of the gravity treatment duration less than timer T1 of timer T2, therefore the situation
Under, timer T2 will be first overtime, and the gravity treatment module 12 determines network type for CDMA, and execution connects
Enter module 13.
In a kind of preferred scheme, the gravity treatment module 12 is described before waiting two timer timing to terminate
Gravity treatment module 12 repeats to obtain the network quality information of each neighbor cell, and from the network type of lowest priority
Start, whether the network quality information for comparing neighbor cell one by one reaches the pre-determined threshold of map network type,
And it is the gravity treatment timing corresponding to the network type for not reaching correspondence thresholding to close comparative result one by one.
Still by taking the gravity treatment scheme of above-mentioned CDMA neighbor cells and GSM neighbor cells as an example, if the gravity treatment
Module 12 judges that the network quality information based on CDMA and two neighbor cells based on GSM is all consistently higher than
Equal to each self-corresponding thresholding, because the gravity treatment duration corresponding to CDMA is less than the gravity treatment corresponding to GSM
Duration, the then it is meant that timer corresponding to CDMA is prior to the timer expiry corresponding to GSM, institute
State gravity treatment module 12 and determine that the network type corresponding to timer overtime at first is CDMA, and perform access
Module 13.
If the network quality information of the neighbor cell based on GSM is consistently higher than equal to corresponding thresholding, and is based on
The network quality information of the neighbor cell of CDMA occurs less than correspondence thresholding, it is meant that, corresponding to CDMA
Timer be closed early before the timeout, then the timer corresponding to GSM will at first time-out, it is described
Gravity treatment module 12 determines that the network type corresponding to timer overtime at first is GSM, and performs AM access module
13。
The AM access module 13 is used for according to identified network type, and selection accesses identified network type
Corresponding neighbor cell.
The AM access module 13 can be according to identified network type, and sending access to corresponding neighbor cell please
Ask, access procedure is performed with the neighbor cell.
Here, it is prior art to perform access procedure with neighbor cell, will not be described in detail herein.

When monitoring to be less than pre-determined threshold with the network quality information of current cell communication, three kinds of network classes are got
The network quality information of the neighbor cell of type, and perform the gravity treatment module 12 in the present embodiment.
It is from low to high GSM that i.e., described first comparison sub-module presets the priority of each network type,
CDMA、LTE.First comparison sub-module first compare the network quality information of the neighbor cell of GSM with
Default GSM thresholdings；If being optionally greater than the thresholding, start the corresponding timer T1 of GSM, and transfer to
Second comparison sub-module continues the network quality information corresponding to primary network station type higher；If it is not, then handing over
Network quality information as corresponding to the second comparison sub-module continues primary network station type higher.
Then, second comparison sub-module continue to compare the network quality information of the neighbor cell of CDMA with
Default CDMA thresholdings；If being optionally greater than the thresholding, first start the corresponding timer T2 of CDMA,
The timer T1 just in timing is restarted again, and continues the network quality letter corresponding to primary network station type higher
Breath；If it is not, then continuing the network quality information corresponding to primary network station type higher.
Then, second comparison sub-module continue to compare the network quality information of the neighbor cell of LTE with it is pre-
If LTE thresholdings；If remaining above equal to the thresholding, first start the corresponding timer T3 of LTE, then restart
Just in the timer T1 and T2 of timing.If now judging each timer, when determining timer T3 time-out, hold
Step S3 in row embodiment three；If it is not, then reacquiring three kinds of networks of the neighbor cell of network type
Quality information, and re-execute and above-mentioned respectively compare.Until default gravity treatment total timing length time-out, then after

When the network quality information of adjacent cell is not up to corresponding pre-determined threshold, network where current neighbor cell is closed
Corresponding to type just timing timer timing, make its no longer timing.When comparative result be higher than etc.
When correspondence thresholding, the gravity treatment module 12 does not restart the timer of correspondence priority, but restarts than working as
Preceding priority it is low just in each timer of timing.
For example, when the first comparison sub-module in the gravity treatment module 12 and the second comparison sub-module compare for the first time
Compared with each neighbor cell of GSM, CDMA and LTE network quality information with respective corresponding thresholding when, start
Timer T1, T2 and T3.During timer T1, T2 and T3 have not timed out, the gravity treatment starts mould
Block 11 obtains the network quality information of these three neighbor cells again, and transfer to first comparison sub-module and
The network quality information that second comparison sub-module compares corresponding to GSM again remains above corresponding thresholding, then not
Give treatment current timer T1.Continue relatively and determine the network quality letter corresponding to the CDMA of newest acquisition
Breath is less than correspondence thresholding, the then timing of Off Timer T2.Continue relatively and determine the LTE of newest acquisition
Corresponding network quality information is higher than correspondence thresholding, then no longer restart timer T3, but restart timer T1.
If now judging each timer, timer T3 time-out is determined, second comparison sub-module is by timer T3
Corresponding LTE types and perform AM access module 13 as the network type of gravity treatment.

First comparison sub-module and the second comparison sub-module are stated in gravity treatment module 12 in each Off Timer timing,
Simultaneously close off the counting of counter.
For example, when first comparison sub-module and the second comparison sub-module compare GSM, CDMA for the first time
During with the network quality information of each neighbor cells of LTE with respective corresponding thresholding, timer T1, T2 are started
And T3, also correspond to that counter D1, D2 are corresponding with D3 is counted as 1.In timer T1, T2 and T3 all
During having not timed out, the gravity treatment starting module 11 obtains the network quality letter of these three neighbor cells for second
Breath, and when performing above-mentioned first comparison sub-module and the second comparison sub-module again, determine corresponding to GSM
Network quality information remains above corresponding thresholding, then disregard current timer T1；Continue relatively and determine
Network quality information corresponding to the CDMA of newest acquisition is less than correspondence thresholding, then Off Timer T2
Timing and the counting of counter D2.Continue relatively and determine the network quality corresponding to the LTE of newest acquisition
Information is higher than correspondence thresholding, then no longer restart timer T3, but restarts timer T1 and by counter D1's
Count value adds 1 and obtains count value 2.If now still without timer expiry, the gravity treatment starting module 11
The network quality information for obtaining these three neighbor cells three times, and first comparison sub-module and second compares
The network quality information that submodule compares GSM neighbor cells remains above corresponding thresholding, then disregard current
Timer T1；Continue relatively and determine the network quality information corresponding to the CDMA of newest acquisition less than correspondence
Thresholding, then continue relatively and determine that the network quality information corresponding to the LTE of newest acquisition is higher than correspondence thresholding,
Then no longer restart timer T3, and judge the count value 2 of counter D1 whether beyond default counting door
Limit, if so, then not restarting timer D1, otherwise restarts timer T1.If second comparison sub-module
Now judge timer T3 time-out, second comparison sub-module is by the LTE types corresponding to timer T3
