It is understandable to enable the above objects, features and advantages of the present invention to become apparent, with reference to embodiment and attached drawing Technical solution of the present invention is described in detail.Said below exemplified by supporting the running of mobile terminal of WCDMA in Idle state It is bright, it will be understood that the network mode that mobile terminal is supported is not limited to WCDMA, can also be GSM, TD-SCDMA etc..
Embodiment one
As shown in Fig. 2, the residence reselecting of the mobile terminal of the present embodiment includes：
Step S100：The period of the alien frequencies or isosystem measurement under standby mode is configured, mobile terminal enters Idle state.
In connected state, base station system can be matched somebody with somebody by eating dishes without rice or wine to issue the measurement of progress alien frequencies or different system to mobile terminal Put.Different from connected state, when requirement that mobile terminal can be based on stand-by power consumption and 3GPP agreements regulation voluntarily configure Idle state The period of alien frequencies or isosystem measurement in one or more radio frames.
In the present embodiment, mobile terminal after standby mode is entered, can measure the mass parameter of current area；It is described to match somebody with somebody Putting the period of the alien frequencies under standby mode or isosystem measurement includes：Mass parameter in current area is less than the first threshold value When, the period of alien frequencies or isosystem measurement is configured, e.g., can be used for measuring alien frequencies or different in next or several radio frames The period of system cell, first threshold value are configured according to 3GPP agreements regulation.
It is appreciated that in other embodiments, mobile terminal can also be pre-configured with standby mould before standby mode is entered The period of alien frequencies or isosystem measurement under formula, e.g., can be used for measuring alien frequencies or different system cell in each radio frames Period；After standby mode is entered, if the mass parameter for measuring current area is less than the first threshold value, start alien frequencies Or isosystem measurement, surveyed according to execution alien frequencies in the period of the period configured in next radio frames or different system Amount.
Step S101：Based on alien frequencies or isosystem measurement, determine to treat re-selecting cell.To alien frequencies or different system in 3GPP agreements Unified test amount has very detailed description, and technical solution of the present invention just repeats no more.The purpose of this step is exactly mobile terminal in sky During not busy state, reselection evaluation is carried out based on the result of alien frequencies or isosystem measurement, determines to treat re-selecting cell.Reselection evaluation, also It is based on the alien frequencies or isosystem measurement as a result, calculating the mass parameter of each adjacent cell of current area；Quality is joined Number is determined as treating re-selecting cell more than the adjacent cell of the second threshold value, and second threshold value is set according to 3GPP agreements regulation Put.By taking WCDMA system as an example, agreement regulation mobile terminal can at most configure 32 alien-frequency districts and 32 different system cells. Since each adjacent cell may be from different network systems, such as may wherein have WCDMA cells, it is also possible to have GSM cell or Person's TD-SCDMA cells, since the signal strength of the cell of different networks can not directly compare, it is therefore desirable to which measurement is obtained The signal strength of cell be mapped in unified criterion.At present, most common criterion is S criterions：I.e. according to survey The signal strength of each adjacent cell measured, calculates cell signal quality value Squal and cell signal strength value Srxlev, when Squal>0 and Srxlev>When 0, mean that mobile terminal in cell reselection may gravity treatment in the adjacent cell, therefore the neighbour is small Area is to treat re-selecting cell.
At least one is being determined behind re-selecting cell by step S101, you can performs step S102 to start.
Step S102：The mobile terminal is set to treat that re-selecting cell is carried out with interior synchronous with interior synchronous condition with meeting.Its In, receiving time of the synchronous condition including the synchronizing information for treating re-selecting cell is located at alien frequencies or isosystem measurement in the band Period in, it is described carry out with it is interior be synchronously included in the period of alien frequencies or isosystem measurement receive described meet with interior same The synchronizing information for treating re-selecting cell of step condition.
, can be according to system message (SIB, the System of the adjacent cell of reception when mobile terminal is in Idle state Information Blocks) prediction treat re-selecting cell synchronizing information receiving time, if the synchronization for treating re-selecting cell The receiving time of information was placed exactly in the period of configured alien frequencies or isosystem measurement, that is, was met with interior synchronization bar Part, then mobile terminal can configure the satisfaction with interior synchronization within the period for performing alien frequencies or isosystem measurement The synchronizing channel for treating re-selecting cell of condition, and treat that re-selecting cell synchronizes with these, i.e., it is synchronous in so-called band.
The synchronizing information for treating re-selecting cell includes system Master Information Block and system information block, in a wcdma system, main Block of information has fixed scheduling parameter and the frequency of occurrences, under its scheduling information is in the broadcast channel for treating re-selecting cell Hair, as long as mobile terminal knows that this treats that the scrambler of re-selecting cell is just easy to listen to its broadcast channel, so as to obtain main information The scheduling information of block, including send the initial frame number of Master Information Block, the repetition period for sending Master Information Block etc..Due to mobile terminal When residing in current area, the frame number of adjacent cell can be read, therefore according to the scheduling information of Master Information Block and read The frame number for treating re-selecting cell, it is possible to determine it is described meet synchronous condition when the reception of the Master Information Block of re-selecting cell Between.Since Master Information Block was repeated with the fixed cycle, when mobile terminal resides in current area, can in certain alien frequencies or Some Master Information Block for treating re-selecting cell is received during person's isosystem measurement.Further, include again in Master Information Block The scheduling information of system information block, therefore the receiving time of system information block is at this moment can be obtained by, so that it is determined that system information When the receiving time of block was located in the period of which alien frequencies or isosystem measurement, so as within the period of the measurement Receive the system information block for treating re-selecting cell.
It should be noted that during certain alien frequencies or isosystem measurement once, it possibly can not obtain some and treat The complete effective synchronizing information of re-selecting cell in multiple alien frequencies or isosystem measurement, it is necessary to could obtain completely.Therefore, on The synchronizing process stated is to perform repeatedly, will be always with treating re-selecting cell as long as mobile terminal is still resided in current area Carry out with interior synchronization, until obtaining complete effective synchronizing information.Wherein, it is complete effectively to refer to described in the synchronizing information satisfaction obtained The reselection requirement of mobile terminal.
Moreover, within the period of certain alien frequencies or isosystem measurement, it is also possible to have and multiple treat the same of re-selecting cell Step information can receive, and at this moment mobile terminal can treat that the synchronizing information of re-selecting cell receives to these parallel.
After step slol, step S103 is performed：It is described mobile whole when when re-selecting cell meets reselection conditions, judging Whether end with meet reselection conditions treats that re-selecting cell completions is synchronous, if so then execute step S107, otherwise execution step S104. In the present embodiment, when the reselection conditions are more than including quality for the duration of quality that is best and being better than the current area Between thresholding.Specifically, it can be judged according to R criterions.By current area and need re-selecting cell according to the progress of R criterions Sequence, the expression cell quality for coming foremost are best.If according to alien frequencies or isosystem measurement as a result, coming foremost When cell is not current area, it is possible to think there is some to treat that the cell quality of re-selecting cell is better than current area.If row The duration that the quality for treating re-selecting cell up front is better than the quality of current area exceedes time threshold, means that this is treated Re-selecting cell meets reselection conditions, and what mobile terminal should switch to that this meets reselection conditions treats re-selecting cell.In other realities Apply in example, the reselection conditions can also include the matter that mass parameter is more than the 3rd threshold value and quality is better than the current area The duration of amount is more than time threshold.
When having one when re-selecting cell meets reselection conditions, meet reselection conditions treats that re-selecting cell may be also step The satisfaction determined in S102 treats re-selecting cell with interior synchronous condition, due in step s 102, mobile terminal using alien frequencies or The period of person's isosystem measurement, treats that re-selecting cell has been carried out with interior synchronous with what this met reselection conditions, then mobile Terminal probably has been completed treats the synchronous of re-selecting cell with this, therefore when the judging result of step S103 is is, moves Dynamic terminal can be directly switch into the re-selecting cell for the treatment of for meeting reselection conditions, that is, perform step S107：The mobile terminal From current area reselect to it is described meet reselection conditions treat re-selecting cell.Compared with prior art, mobile terminal need not wait until After Target cell (meet in other words reselection conditions after re-selecting cell) is determined, then discharge current area channel configuration, into The channel configuration of row Target cell, after synchronous with Target cell completion, could complete gravity treatment, therefore not only accelerate cell reselection Speed, be also greatly reduced lose network side message probability.
When the judging result of step S103 is no, step S104 is performed：Make the mobile terminal release current area Channel configuration, then performs step S105 and step S106.
Step S105：Receive the synchronizing information for treating re-selecting cell for meeting reselection conditions.
Step S106：Judge mobile terminal whether with it is described meet reselection conditions treat that re-selecting cell completion is synchronous, when sentencing When disconnected result is no, then return to step S105, continues to；When judging result is to be, then step S107 is performed：The movement Terminal from current area reselect to it is described meet reselection conditions treat re-selecting cell.
It should be noted that there may be two kinds of situations for the execution of step S105：
A kind of situation is, it is described meet reselection conditions treat that re-selecting cell is also to meet to treat re-selecting cell with inter-sync, By the interior synchronization of the band of step S102, mobile terminal may also fail to complete to treat that re-selecting cell is same with what this met reselection conditions Step, then after the channel configuration that mobile terminal described in step S104 discharges the current area, move described in step S105 Terminal continues to the synchronizing information for treating re-selecting cell for meeting reselection conditions.In other embodiments, can also first after After continued access receives the synchronizing information after re-selecting cell for meeting reselection conditions until completing synchronization, then discharge the current area Channel configuration.It should be understood that when some is when re-selecting cell meets reselection conditions, work as due to being subject to mobile terminal to be resident The duration and the number of progress alien frequencies or isosystem measurement of preceding cell are equal to the influence of factor, and mobile terminal may also be simultaneously Do not complete and treat the synchronous of re-selecting cell with what this met reselection conditions, therefore mobile terminal can first discharge the current area Channel configuration, continues to the synchronizing information for treating re-selecting cell for meeting reselection conditions.In general, in the synchronization of step S102 During, mobile terminal can more or less get the Partial synchronization information for treating re-selecting cell for meeting reselection conditions, The synchronizing information obtained in step s 102 still can be used, and continue in step S105 the reselection conditions that meet Treat other synchronizing informations of re-selecting cell.It can be seen from the above that relative to the prior art, remain to so that the time that synchronizing process expends subtracts Few, gravity treatment speed can be accelerated, and decrease the probability for losing network side message.
Another situation is, it is described meet reselection conditions treat that re-selecting cell is not to meet to treat that gravity treatment is small with inter-sync Area, then after the channel configuration that mobile terminal described in step S104 discharges the current area, in step S105, also need to configure It is described meet reselection conditions treat the synchronizing channel of re-selecting cell, then receive it is described meet reselection conditions treat the same of re-selecting cell Information is walked, that is, after channel configuration, receives the whole synchronizing informations for treating re-selecting cell for meeting reselection conditions.
The residence reselecting of the mobile terminal of the present embodiment, can utilize alien frequencies under the standby mode of mobile terminal configuration Or the isosystem measurement period, met the synchronization for treating re-selecting cell with interior synchronous condition parallel.Once some is treated When re-selecting cell meets reselection conditions, it is possible to which be immediately switched to that this meets reselection conditions treats re-selecting cell, accelerates shifting The flow of dynamic cell reselection of the terminal in Idle state.Moreover, reduce the time that channel is interrupted so that lose network side and disappear The probability of breath is greatly reduced, and improves user experience.
In addition, it any ought treat that re-selecting cell meets reselection conditions, even if mobile terminal does not meet reselection conditions with this Treat that re-selecting cell is fully finished synchronization, also can continue synchronization, therefore remain on the basis of the synchronous progress completed Accelerate the speed of mobile terminal cell reselection, and reduce the probability for losing network side message.
