System uses 02, and China Telecom's cdma system uses 03.So as to which the PLMN of China Mobile is 46000 or 46002, CHINAUNICOM
PLMN is that the PLMN of 46001, China Telecom is 46003.Mobile terminal will realize communication function, must be linked into PLMN.Move
Dynamic terminal first selectes a PLMN, once have selected PLMN, mobile terminal can be using initial cell selection or storage information cell
Selection course, is found suitable cell and is resident, with the service provided using the cell, while listening to the control channel of the cell.
The state of usual mobile terminal is divided into 3 kinds：1st, dummy status, the power supply of mobile terminal is not turned on；2nd, idle pulley,
The power supply of mobile terminal has already turned on and has resided in a cell, but without call or data transmission service；3rd, mould is connected
Formula, mobile terminal is in call or carries out data transmission the state of business.Wherein at the idling mode, mobile terminal will listen to neighbour
Nearly cell carry out power measurement, response paging, it is main z z z go out, carry out location updating, also according to measured value and to receive
Broadcast system message calculate cell reselection antenna parameter carry out cell reselection, so as to reside in priority it is higher/channel quality
More preferable cell, makes cell preferably provide service for mobile terminal.So-called serving cell refers to mobile phone just resident cell, and
Adjacent cell is that candidate turns into the cell of serving cell.When the downstream signal link failure of mobile terminal or current service cell
When being changed into occurring situations such as resistance, mobile terminal can start cell reselection.During gravity treatment, signal instruction is received according to adjacent cell and surveyed
The parameters such as the reception signal instruction measured value of value and serving cell are carried out, and join such parameter as gravity treatment in the present embodiment
Number, when mobile terminal carries out cell reselection operation, determines the correction factor of reselecting parameters.Fig. 6 is refer to, mobile terminal is current
Resident serving cell is some cell determined, has multiple adjacent cells with this serving cell, wherein cannot function as moving
The neighbor cell of dynamic terminal access is non-adjacent cells, and the neighbor cell that can be accessed as mobile terminal is adjacent cell, adjacent
Nearly cell at least meets following condition：(1) mobile terminal can receive broadcast singal from the network where the cell；(2) if moved
Dynamic terminal user wants to send calling, and it can be successfully accessing system；(3) mobile terminal user can receive in the cell carrys out automatic network
The paging of other users.Specifically, adjacent cell can be as network it is determined that after serving cell where mobile terminal, will can access
Adjacent cell list be issued to mobile terminal, so that it is determined that the accessible adjacent cell of mobile terminal.Determined in adjacent cell
Afterwards, because of the environmental difference of different adjacent cells, the telecommunication service quality that can be provided also is differed, according to each neighbour of mobile terminal
The session services record of nearly cell determines the correction factor of each proximity based cell re-selection parameter, and wherein session services record is exhaled with call
The frequency of failure, dropped calls number of times etc. is made to represent the parameter characterization of telecommunication service quality.After correction factor determination, using each
The corresponding correction factor in adjacent cell is modified respectively to the reselecting parameters of each adjacent cell, so that reselecting parameters are more accurate
Each adjacent cell of sign communication quality, so as to select the more preferable adjacent cell of channel quality.
The reselecting parameters of each adjacent cell, based on the correction factor, are modified to benchmark reselecting parameters by step S20；
Further, it is determined that the reselecting parameters of all adjacent cells neighbouring with serving cell where mobile terminal are repaiied
After positive coefficient, according to the correction factor of different adjacent cells, the reselecting parameters to corresponding adjacent cell are modified, and its is heavy
Select parameters revision to attach most importance to and take as an elective course positive coefficient.The historical data that correction factor is failed by the call of the conventional mobile terminal in each adjacent cell
Calculate, the height of frequency, i.e. communication quality that the history call so as to characterize each adjacent cell fails uses this to correct
Coefficient is modified to reselecting parameters, and reselecting parameters can be made more accurately to characterize the communication quality of each adjacent cell, added
The probability of the more preferable adjacent cell of channel quality is selected from each adjacent cell.The mode of amendment can be by reselecting parameters and amendment
Coefficient does multiplication operation, both can also be done into additive operation, with the call failure frequency by each adjacent cell in the past, characterizes
Current communication quality.When using multiplication operation, the value of correction factor is less than or equal to 1, when terminal never occurs in certain cell
The situation of call failure is crossed, then its correction factor can be represented with 1, when occurring the situation of call failure, then it corrects system
Number is less than 1, to represent that there was the situation that call fails the adjacent cell with reference to from the point of view of history parameters, the matter so that it converses at present
Amount is smaller than the reselecting parameters obtained by calculating.Understandably, when the call frequency of failure of adjacent cell is more, then its history is conversed
Quality is poorer, so that when correcting mode is multiplication operation, correction factor is smaller, reselecting parameters is modified to benchmark reselecting parameters
It is smaller, represent that the speech quality of this adjacent cell is poor；When correcting mode is additive operation, correction factor is bigger, makes accordingly
Reselecting parameters are modified to that benchmark reselecting parameters are smaller, represent that the speech quality of this adjacent cell is poor.
Step S30, obtains the effective gravity treatment ginseng for meeting cell reselection criterion from the benchmark reselecting parameters of each adjacent cell
Number, and the maximum corresponding adjacent cell of effective reselecting parameters of numerical value is defined as re-selecting cell.
Further, correction factor is being used, reselecting parameters is being modified to after benchmark reselecting parameters, because of benchmark gravity treatment ginseng
Several otherness, in fact it could happen that it is logical that the communication quality that adjacent cell the can be provided serving cell more current than mobile terminal is provided
Letter is of poor quality, if on the contrary dropping the communication service of mobile terminal as the persistent district of mobile terminal such adjacent cell
It is low, so the adjacent cell that such communication quality should be worse than into current service cell is excluded.It is provided with the present embodiment small
Area's reselection criterion, by cell reselection criterion, chooses effective reselecting parameters from the benchmark reselecting parameters of each adjacent cell, this choosing
The communication quality that the corresponding adjacent cell of effective reselecting parameters taken can be provided can ensure that than the clothes where current mobile terminal
The good communication quality that business cell is provided, so that the adjacent cell exclusion that communication quality is worse than current service cell will be provided.
Effective gravity treatment of the communication quality better than the current serving cell for providing service is chosen from the benchmark reselecting parameters of each adjacent cell
, it is necessary to from effective reselecting parameters, determine an optimal cell as re-selecting cell after parameter.Specifically, effectively weight is chosen
The maximum effective reselecting parameters of numerical value in parameter are selected, the adjacent cell with this effective reselecting parameters are regard as re-selecting cell.This
Outside, if gravity treatment correction value only one of which, directly it regard this corresponding adjacent cell of gravity treatment correction value as re-selecting cell.Or,
The effective reselecting parameters for meeting cell reselection criterion are not present in benchmark reselecting parameters, then service where illustrating mobile terminal is small
The communication quality of the adjacent cell in area is not better than current service cell, then continues drop current service cell and be used as mobile terminal
It is resident, without gravity treatment.To ensure to provide relative optimal communication quality to mobile terminal, so as to ensure the call clothes of mobile terminal
Business.
The residence reselecting of technical solution of the present invention, when mobile terminal receives cell reselection instruction, according to movement
The session services record of each adjacent cell of terminal determines the correction factor of each proximity based cell re-selection parameter, uses correction factor counterweight
Select parameter to be modified, obtain benchmark reselecting parameters, meet the effective of cell reselection criterion in benchmark reselecting parameters so as to obtain
Reselecting parameters, and then the maximum corresponding adjacent cell of effective reselecting parameters of numerical value is defined as re-selecting cell.This programme passes through
Reselecting parameters to each adjacent cell of mobile terminal are modified, and revised reselecting parameters can more accurately embody each
The service status of adjacent cell, so as to select the good cell of service status, improves the session services quality of mobile terminal.
Further, it is described when mobile terminal receives cell weight in another embodiment of residence reselecting of the present invention
During choosing instruction, the correction factor for determining each proximity based cell re-selection parameter is recorded according to the session services of each adjacent cell of mobile terminal
The step of include：
Step S11, when mobile terminal receives cell reselection instruction, obtains mobile terminal each neighbour in preset time
Call Time To Failure corresponding to the call frequency of failure of nearly cell and each call failure；
Step S12, based on the call frequency of failure, call Time To Failure and preset time, determines each adjacent cell
Reselecting parameters correction factor.
Further, the communication quality that the serving cell where mobile terminal is provided is poor, and the session services of mobile terminal are poor
When, mobile terminal re eligible adjacent cell is used as new persistent district.Wherein gravity treatment instruction triggering can be：Mobile terminal is not
Can receive broadcast singal from the network where current service cell, or mobile terminal can not successful access system, or
Person's mobile terminal can not receive paging of network other users etc. in serving cell.When mobile terminal receives cell weight
During choosing instruction, mobile terminal the call frequency of failure of each adjacent cell and each call failure institute in preset time are obtained
The corresponding air time.Understandably, cell communication quality is influenceed by its own factor and surrounding environment, such as access cell
Mobile terminal quantity and the barrier etc. of surrounding.And change over time, these influence factors can also change,
The quantity for such as accessing the mobile terminal of cell is reduced, and the barrier of surrounding may be removed, so that the communication matter of cell
Amount is reduced towards the aspect development improved, the call frequency of failure of mobile terminal, may also equally be developed towards the aspect of variation, be made shifting
The call frequency of failure increase of dynamic terminal.So the present embodiment is previously provided with preset time, obtain mobile whole in preset time
The call frequency of failure and corresponding call Time To Failure in each adjacent cell are held, and the duration of this preset time should closed
In the range of reason.If set of time is oversize, possible cell is changed by external environment, and the communication quality before long-time is simultaneously
Current communication quality can not be reflected；And set of time is too short, the communication quality of this cell can not be fully demonstrated.
According to the call frequency of failure of each cell in preset time and corresponding call Time To Failure, in conjunction with it is current when
Between, determine the correction factor of the reselecting parameters of each adjacent cell.Specifically, determining shown in correction factor such as formula (1)：
Wherein, n is in preset time Δ with i-th of adjacent areatThe number of times of interior call failure, ΔRRepresent single unsuccessfully to gravity treatment
The correction of parameter, for the empirical value pre-set, tcRepresent current time, tkRepresent the time of kth time call failure, ΔtFor
Preset time.
Δ in formula (1)RFor the empirical value pre-set, (tc-Δt) be used to determine the beginning timing time of preset time
Point, such as current time are 10 points, and preset time is 30 minutes, then by tc-ΔtCan determine that default timing time point is 9: 30.And
tk-(tc-Δt) represent occur the distance of the time gap current point in time of kth time call failure, when more remote from current time, i.e.,
Beginning timing time point is left nearer, so that tk-(tc-Δt) numerical value is smaller, is 9: 40 such as when the time of kth time call failure,
9: 30 are then subtracted, institute's value is 10, and when Time To Failure is 9: 35, then institute's value is 5.And then cause by formula
(1) numerical value of the correction factor obtained by calculating is smaller；Conversely as, t nearer from current timek-(tc-Δt) numerical value is bigger, make
The numerical value of correction factor obtained by must being calculated by formula (1) is bigger.In addition, being lost to all calls occurred in preset time
The influence for losing the number of times speech quality current to cell is added up, and when call frequency of failure generation is more, accumulated value is bigger, i.e.,
The speech quality influence current on cell is bigger.The present embodiment is according to the call frequency of failure of different adjacent cells and corresponding
Call Time To Failure, is calculated using calculating formula (1) and obtains correction factor, be used as adjacent cell the probability counterweight failed of conversing occur
Select parameter to be modified, but reselecting parameters are more accurate, improve the probability of the good adjacent cell of selection speech quality.
Further, it is described when mobile terminal receives cell weight in another embodiment of residence reselecting of the present invention

Include before the step of corresponding call Time To Failure：
Step S13, when mobile terminal call fails, record call Time To Failure, and mobile terminal during call failure
The cell at place；
Step S14, the call Time To Failure is saved in corresponding cell list.
Understandably, in order to obtain the call frequency of failure and corresponding call Time To Failure of each adjacent cell,
When call failure occurs for mobile terminal, it is necessary to which the situation to this call failure carries out record preservation.Specifically, mobile terminal
In be provided with each cell cell list, when mobile terminal current service cell occur call failure when, to this call fail
Time and the serving cell that is currently located recorded；And this record is stored in the corresponding cell list of serving cell
In.Current area such as mobile terminal is A, and there are B, C in adjacent cell, so that cell list includes A, B, C, current area A occurs
Call failure, by this call Time To Failure record in the cell list of A cells, after a hour, occurs call failure again, after
This call Time To Failure record of continuous drop is in the cell list of A cells；Hereafter it is C cells by A cell reselections by serving cell, when
When call failure occurs for C cells, by this call Time To Failure record in the cell list of C cells.When receiving cell weight
When choosing instruction carries out cell reselection, the data stored in the cell list that each adjacent cell is obtained from mobile terminal, to carry out
The calculating of the correction factor of each cell, so as to gravity treatment parameters revision.

After the reselecting parameters of each adjacent cell are determined by formula (2), reselecting parameters are modified.Specifically, originally
Embodiment is by the way of both subtract each other and seek difference, shown in such as formula (3)：
Ri'=Ri-ΔRi (3)
Wherein Ri' attach most importance to and take as an elective course positive coefficient, when adjacent cell is in preset time, the call frequency of failure of generation is excessive
When, correction factor ΔRiValue is corresponding larger, so that Ri' value it is smaller；Accordingly, when adjacent cell is in preset time, occur
The call frequency of failure it is less when, correction factor ΔRiValue is corresponding smaller, so that Ri' value it is larger.So as to pass through correction factor
