Embodiment
Embodiment one
As shown in Figure 2, the residence reselecting of the mobile terminal of the present embodiment comprises:
Step S100: the alien frequencies under configuration standby mode or the time period of isosystem measurement, mobile terminal enters Idle state.
At connected state, base station system can issue to mobile terminal the measurement configuration carrying out alien frequencies or different system by eating dishes without rice or wine.Be different from connected state, alien frequencies when mobile terminal can specify to configure Idle state voluntarily based on the requirement of stand-by power consumption and 3GPP agreement in one or more radio frames or the time period of isosystem measurement.
In the present embodiment, mobile terminal after entering standby mode, can measure the mass parameter of current area; Alien frequencies under described configuration standby mode or the time period of isosystem measurement comprise: when the mass parameter of current area is less than the first threshold value, the time period of configuration alien frequencies or isosystem measurement, as, may be used for the time period of measuring alien frequencies or different system cell in the next one or several radio frames, described first threshold value is arranged according to 3GPP agreement regulation.
Be appreciated that in other embodiments, mobile terminal also can time period of alien frequencies before entering standby mode under pre-configured standby mode or isosystem measurement, e.g., may be used for the time period of measuring alien frequencies or different system cell in each radio frames; After entering standby mode, if when the mass parameter measuring current area is less than the first threshold value, start alien frequencies or isosystem measurement, perform alien frequencies or isosystem measurement according in this time period in next radio frames configured time period.
Step S101: based on alien frequencies or isosystem measurement, determines to treat re-selecting cell.Have very detailed description to alien frequencies or isosystem measurement in 3GPP agreement, technical solution of the present invention just repeats no more.The object of this step, be exactly mobile terminal when Idle state, the result based on alien frequencies or isosystem measurement carries out reselection evaluation, determines to treat re-selecting cell.Reselection evaluation, namely based on the result of described alien frequencies or isosystem measurement, calculates the mass parameter of each adjacent cell of current area; Adjacent cell mass parameter being greater than the second threshold value is defined as treating re-selecting cell, and described second threshold value is arranged according to 3GPP agreement regulation.For WCDMA system, agreement regulation mobile terminal can configure at most 32 alien-frequency districts and 32 different system cells.Because each adjacent cell may from different network systems, such as wherein may there is WCDMA community, also GSM community or TD-SCDMA community may be had, because the signal strength signal intensity of the community of different networks cannot directly compare, therefore need the signal strength signal intensity measuring the community obtained to be mapped in unified criterion.At present, the most frequently used criterion is S criterion: namely according to the signal strength signal intensity measuring each adjacent cell obtained, calculation plot signal quality value Squal and cell signal strength value Srxlev, as Squal>0 and Srxlev>0 time, possibility gravity treatment is in this adjacent cell when cell reselection just to represent mobile terminal, and therefore this adjacent cell is and treats re-selecting cell.
Determine through step S101 at least one behind re-selecting cell, namely can start perform step S102.
Step S102: make described mobile terminal with meet be with inter-sync condition treat that band inter-sync is carried out in re-selecting cell.Wherein, treat that the time of reception of the synchronizing information of re-selecting cell is positioned at the time period of alien frequencies or isosystem measurement described in described band inter-sync condition comprises, described in receive the synchronizing information treating re-selecting cell of described satisfied band inter-sync condition in time period of carrying out being with inter-sync to be included in alien frequencies or isosystem measurement.
When mobile terminal is at Idle state, can according to the system message (SIB of the adjacent cell received, System Information Blocks) predict the time of reception treating the synchronizing information of re-selecting cell, if described in treat that the time of reception of the synchronizing information of re-selecting cell is just in time positioned at configured alien frequencies or the time period of isosystem measurement, namely band inter-sync condition is met, so mobile terminal just can within the time period performing alien frequencies or isosystem measurement, configure the synchronizing channel treating re-selecting cell of described satisfied band inter-sync condition, and treat that re-selecting cell is carried out synchronous with these, i.e. so-called band inter-sync.
Describedly treat that the synchronizing information of re-selecting cell comprises system Master Information Block and system information block, in a wcdma system, Master Information Block has fixing scheduling parameter and the frequency of occurrences, its schedule information issues in the broadcast channel of re-selecting cell described treating, as long as mobile terminal knows that this scrambler treating re-selecting cell is just easy to listen to its broadcast channel, thus obtain the schedule information of Master Information Block, comprise the initial frame number sending Master Information Block, the repetition period etc. sending Master Information Block.Due to mobile terminal reside in current area time, the frame number of adjacent cell can be read, therefore according to the schedule information of Master Information Block and the frame number treating re-selecting cell described in reading, the described time of reception treating the Master Information Block of re-selecting cell meeting synchronous condition can just be determined.Because Master Information Block repeated with the fixed cycle, when mobile terminal resides in current area, the Master Information Block that certain treats re-selecting cell can be received in the process of certain alien frequencies or isosystem measurement.Further, the schedule information of system information block is included again in Master Information Block, therefore the time of reception of system information block can at this moment just be obtained, thus the time of reception of certainty annuity block of information is when being positioned at the time period of which alien frequencies or isosystem measurement, thus the system information block that this treats re-selecting cell can be received within the time period of this measurement.
It should be noted that, in the process of certain alien frequencies once or isosystem measurement, possibly cannot obtain the complete effective synchronizing information that certain treats re-selecting cell, need repeatedly alien frequencies or isosystem measurement could obtain complete.Therefore, above-mentioned synchronizing process repeatedly to perform, as long as mobile terminal still resides in current area, will always with treat that band inter-sync is carried out in re-selecting cell, until obtain complete effective synchronizing information.Wherein, complete effective reselection requirement that the synchronizing information obtained meets described mobile terminal that refers to.
And within the time period of certain alien frequencies or isosystem measurement, also may have and multiplely treat that the synchronizing information of re-selecting cell can receive, at this moment mobile terminal can walk abreast and treat that the synchronizing information of re-selecting cell receives to these.
After step slol, perform step S103: when meeting reselection conditions until re-selecting cell, judge described mobile terminal whether with meet reselection conditions to treat that re-selecting cell completes synchronous, if then perform step S107, otherwise execution step S104.In the present embodiment, it is best and the duration being better than the quality of described current area is greater than time threshold that described reselection conditions comprises quality.Concrete, can judge according to R criterion.Sorted according to R criterion in current area and the re-selecting cell that needs, the expression cell quality coming foremost is best.According to the result of alien frequencies or isosystem measurement, if when coming the Bu Shi current area, community of foremost, just can think to have and somely treat that the cell quality of re-selecting cell is better than current area.If what come foremost treats that the quality of re-selecting cell is better than the duration overtime thresholding of the quality of current area, just represent that this treats that re-selecting cell meets reselection conditions, what mobile terminal should switch to that this meets reselection conditions treats re-selecting cell.In other embodiments, described reselection conditions also can comprise mass parameter and be greater than the 3rd threshold value and the duration that quality is better than the quality of described current area is greater than time threshold.
When there being one to meet reselection conditions until re-selecting cell, meet reselection conditions treat re-selecting cell may also be the satisfied band inter-sync condition determined in step S102 treat re-selecting cell, due in step s 102, mobile terminal utilizes the time period of alien frequencies or isosystem measurement, what met reselection conditions with this treats that band inter-sync has been carried out in re-selecting cell, so mobile terminal has probably completed and has treated the synchronous of re-selecting cell with this, therefore when the judged result of step S103 is for being, what mobile terminal just can be directly switch into that this meets reselection conditions treats re-selecting cell, namely perform step S107: described mobile terminal reselect to from current area described meet reselection conditions treat re-selecting cell.Compared with prior art, mobile terminal is without the need to after by the time determining Target cell (meet in other words reselection conditions until re-selecting cell), discharge the channel configuration of current area again, carry out the channel configuration of Target cell, with Target cell complete synchronous after, just gravity treatment can be completed, therefore not only accelerate the speed of cell reselection, also greatly reduce the probability losing network side message.
When the judged result of step S103 is no, perform step S104: make described mobile terminal discharge the channel configuration of current area, then perform step S105 and step S106.
Step S105: receive the described synchronizing information treating re-selecting cell meeting reselection conditions.
Step S106: judge mobile terminal whether with described meet reselection conditions to treat that re-selecting cell completes synchronous, when judged result is no, then return step S105, continue to receive; When judged result is for being, then perform step S107: described mobile terminal reselect to from current area described meet reselection conditions treat re-selecting cell.
It should be noted that, may there are two kinds of situations in the execution of step S105:
A kind of situation is, described meet reselection conditions treat that re-selecting cell is also meet band inter-syncly to treat re-selecting cell, through the band inter-sync of step S102, what mobile terminal also may fail to meet with this reselection conditions treats that re-selecting cell is synchronous, then discharge the channel configuration of described current area in mobile terminal described in step S104 after, described in step S105, mobile terminal continues to receive the described synchronizing information treating re-selecting cell meeting reselection conditions.In other embodiments, also can first continue to receive described meet reselection conditions the synchronizing information until re-selecting cell until complete synchronous after, then discharge the channel configuration of described current area.Understandable, when some meet reselection conditions until re-selecting cell time, because the duration that is subject to the resident current area of mobile terminal and the number of times that carries out alien frequencies or isosystem measurement equal the impact of factor, mobile terminal also may not complete to meet reselection conditions with this treat the synchronous of re-selecting cell, therefore mobile terminal first can discharge the channel configuration of described current area, continues to receive the described synchronizing information treating re-selecting cell meeting reselection conditions.Usually, in the synchronizing process of step S102, mobile terminal more or less can get the described Partial synchronization information treating re-selecting cell meeting reselection conditions, the synchronizing information obtained in step s 102 still can use, and receives described other synchronizing informations treating re-selecting cell meeting reselection conditions in the continued access of step S105 relaying.As can be seen here, relative to prior art, still can make the time decreased that synchronizing process expends, gravity treatment speed can be accelerated, and decreases the probability losing network side message.
Another kind of situation is, described meet reselection conditions treat that re-selecting cell is not meet band inter-syncly to treat re-selecting cell, then discharge the channel configuration of described current area in mobile terminal described in step S104 after, in step S105, also need to configure the described synchronizing channel treating re-selecting cell meeting reselection conditions, receive the described synchronizing information treating re-selecting cell meeting reselection conditions again, namely after channel configuration, receive the described whole synchronizing information treating re-selecting cell meeting reselection conditions.
The residence reselecting of the mobile terminal of the present embodiment, can utilize alien frequencies or isosystem measurement time period under the standby mode of mobile terminal configuration, parallel carry out meeting band inter-sync condition treat the synchronous of re-selecting cell.Treat that re-selecting cell meets reselection conditions once some, what be just likely switched to that this meets reselection conditions immediately treats re-selecting cell, accelerates the flow process of the cell reselection of mobile terminal when Idle state.And, decrease the channel interrupted time, the probability losing network side message is declined greatly, improves Consumer's Experience.
In addition, treat that re-selecting cell meets reselection conditions when arbitrary, even if mobile terminal do not meet with this reselection conditions to treat that re-selecting cell completes completely synchronous, also can on the basis of the synchronous progress completed, proceed synchronous, therefore still can accelerate the speed of mobile terminal cell reselection, and reduce the probability losing network side message.

When determining at least one behind re-selecting cell, treat that if determined the time of reception of the synchronizing information of re-selecting cell is not all at the alien frequencies of current configuration or in the time period of isosystem measurement, then can adjust the time period of alien frequencies or isosystem measurement, make in the time period of alien frequencies after the adjustment or isosystem measurement, to receive the synchronizing information that at least one treats re-selecting cell.
When determining at least one behind re-selecting cell, treat that if determined re-selecting cell only has the time of reception of minority community at the alien frequencies of current configuration or in the time period of isosystem measurement, and have the time of reception of most community not at the alien frequencies of current configuration or in the time period of isosystem measurement, then can adjust the time period of alien frequencies or isosystem measurement, make the synchronizing information treating re-selecting cell that can receive a greater number in the time period of alien frequencies after the adjustment or isosystem measurement.
When determining at least one behind re-selecting cell, can adjust the time period of alien frequencies or isosystem measurement, making can received signal quality one or more synchronizing information treating re-selecting cell preferably in the time period of alien frequencies after the adjustment or isosystem measurement.

It should be noted that, the present embodiment does not limit the concrete execution sequence of step S202, be appreciated that, in step S201, step S202 can determine that at least one is behind re-selecting cell, execution after the reselection evaluation of one or more adjacent cell is completed, also after step S203 starts to perform, can perform after the alien frequencies of a radio frames or isosystem measurement complete.
After step S201, perform step S204: when meeting reselection conditions until re-selecting cell, judge described mobile terminal whether with meet reselection conditions to treat that re-selecting cell completes synchronous, if then perform step S208, otherwise execution step S205.
Step S205: make described mobile terminal discharge the channel configuration of current area, then perform step S206 and step S207.
Step S206: receive the described synchronizing information treating re-selecting cell meeting reselection conditions.
Step S207: judge mobile terminal whether with described meet reselection conditions to treat that re-selecting cell completes synchronous, when judged result is no, then return step S206, continue to receive; When judged result is for being, then perform step S208: described mobile terminal reselect to from current area described meet reselection conditions treat re-selecting cell.

Further, adjust the time period of alien frequencies under described standby mode or isosystem measurement neatly, at least one time of reception until re-selecting cell is made to be positioned at the time period of the alien frequencies after adjustment or isosystem measurement, like this, complete within the time period of alien frequencies or isosystem measurement and treat that probability that the synchronizing information of re-selecting cell receives can be higher or can receive the synchronizing information more treating re-selecting cell, once need after re-selecting cell meets reselection conditions, described mobile terminal gravity treatment just can be directly made to treat re-selecting cell to what meet reselection conditions, thus accelerate the process of described mobile terminal cell reselection further, decrease the probability losing network side message.
In addition, treat that re-selecting cell meets reselection conditions when arbitrary, even if mobile terminal do not meet with this reselection conditions to treat that re-selecting cell completes completely synchronous, also can on the basis of the synchronous progress completed, proceed synchronous, therefore still can accelerate the speed of mobile terminal cell reselection, and reduce the probability losing network side message.
Embodiment three
The reselection evaluation of embodiment one and two and band inter-sync are parallel within the time period of alien frequencies or isosystem measurement to be carried out, further, the present embodiment utilizes band inter-sync demand schedule to realize reselection evaluation and inter-sync the walking abreast of band is carried out, Fig. 3 shows the detail flowchart of the residence reselecting of the mobile terminal of the present embodiment, specifically comprises:
Step S300: the alien frequencies under configuration standby mode or the time period of isosystem measurement, enter Idle state.Specifically can the step S100 of reference example one.
Step S301: the time period entering alien frequencies or isosystem measurement.
When mobile terminal is at Idle state, according to 3GPP agreement regulation, the signal strength signal intensity of current Serving cell can be measured, if the signal strength signal intensity of Serving cell is deteriorated to a certain extent, mass parameter as current area is less than the first threshold value, then start alien frequencies or isosystem measurement.
After within the time period entering alien frequencies or isosystem measurement, perform alien frequencies or isosystem measurement, and can parallel execution of steps S302 and step S303.
Step S302: carry out reselection evaluation, determines to treat re-selecting cell.Carry out reselection evaluation to each adjacent cell, to determine whether as treating re-selecting cell, concrete enforcement can step S101 in reference example one.
Then performing step S306: what judgement was determined treats that re-selecting cell is the need of carrying out band inter-sync, when the judged result of this step is yes, then performing step S307, otherwise performing step S308.
According to protocol requirement, mobile terminal will reselect to arbitrary when re-selecting cell from current area, first needs to treat that with this re-selecting cell is carried out synchronous, obtains that mobile terminal is resident treats the necessary synchronizing information in re-selecting cell to this.In the present embodiment, what the judgement of step S306 was determined treats that re-selecting cell can be judge whether this mass parameter treating re-selecting cell meets reselection requirement the need of carrying out band inter-sync, namely this treats that the signal quality of re-selecting cell is better, after reselection evaluation completes, be likely confirmed as the Target cell of gravity treatment; Or, what judgement was determined treats that re-selecting cell also can be judge that this treats whether re-selecting cell meets band inter-sync condition, and namely this treats whether the time of reception of the synchronizing information of re-selecting cell is positioned at the alien frequencies of current configuration or the time period of isosystem measurement the need of carrying out band inter-sync.
Step S307: treat that re-selecting cell joins in band inter-sync demand schedule by described, continue to perform step S308.Namely, when meeting band inter-sync conditioned disjunction mass parameter until re-selecting cell and meeting reselection requirement, that in band inter-sync demand schedule, records that described satisfied band inter-sync conditioned disjunction mass parameter meets reselection requirement treats re-selecting cell.Understandable, it is multiple that what step S302 determined treat that re-selecting cell can have, wherein, meet band inter-sync conditioned disjunction mass parameter meet reselection requirement to treat that reselection conditions also can have multiple, be recorded in band inter-sync demand schedule, band inter-sync operation is afterwards with regard to only for treating that re-selecting cell is carried out in this band inter-sync demand schedule.
Step S308: the reselection evaluation having judged whether all adjacent cells, if then perform step S309, otherwise returns step S301, waits for and enters time period of alien frequencies or isosystem measurement next time, continuing execution step S302 and S303 within this time period.
Step S303: the time period adjusting described alien frequencies or isosystem measurement.In the present embodiment, treat that re-selecting cell to be added in band in demand schedule due to what perform that mass parameter can meet reselection requirement by step S306 and S307, therefore, the time of reception treating the synchronizing information of re-selecting cell that can record in measuring tape inter-sync demand schedule in advance in step S303, and the time period of alien frequencies under described standby mode or isosystem measurement is adjusted neatly according to the time of reception of prediction, make the time period of the alien frequencies after adjusting or isosystem measurement the described mass parameter in receiving belt inter-sync demand schedule can meet the synchronizing information treating re-selecting cell of reselection requirement.
In other embodiments, the concrete enforcement adjusting the time period of described alien frequencies or isosystem measurement can the step S202 of reference example two, such as, the time period of described alien frequencies or isosystem measurement can also be adjusted, make the time period of the alien frequencies after adjusting or isosystem measurement can the synchronizing information treating re-selecting cell of a greater number in receiving belt inter-sync demand schedule.
It should be noted that, for ease of the concrete enforcement of the present embodiment is described, add step S303 in fig. 3, be appreciated that, step S303 can only perform once, and afterwards enter the time period of alien frequencies or isosystem measurement several times after, skip step S303 and perform step S304 and S305; Certainly, step S303 also can according to the actual requirements, and be in due course execution, and the present embodiment does not limit the execution number of times of step S303.
Step S304: determine the time of reception treating the synchronizing information of re-selecting cell in described band inter-sync demand schedule.In this step, can by the current band inter-sync demand schedule of traversal, determine to be recorded in described band inter-sync demand schedule, be suitable for reception beginning and ending time for the treatment of the synchronizing information of re-selecting cell of receiving within the time period of current alien frequencies or isosystem measurement.It should be noted that, when also not determining until re-selecting cell, described band inter-sync demand schedule is empty, therefore can not perform step S304 and S305.
After step S304, continue to perform step S305: configuration needs to receive the synchronizing channel treating re-selecting cell of synchronizing information, receives current alien frequencies or the synchronizing information in the isosystem measurement time period.Understandable, when there being multiple synchronizing information until re-selecting cell can receive within the time period of current alien frequencies or isosystem measurement, mobile terminal can perform multiple band inter-sync operation treating re-selecting cell respectively.The concrete enforcement of step S304 and step S305 can step S102 in reference example one, repeats no more herein.
Further, after the reselection evaluation of all adjacent cells completes, continue to perform step S309: what judge whether to meet reselection conditions treats re-selecting cell, if then perform step S310, otherwise return step S301.The service quality had to make mobile terminal, needs mobile terminal gravity treatment in time can switch to the measured Serving cell of matter, concrete judgement, can step S103 in reference example one, repeats no more herein.
Step S310: judge described meet reselection conditions treat whether re-selecting cell is recorded in described band inter-sync demand schedule, if then perform step S311, otherwise perform step S312.
Step S311: the described synchronizing information treating re-selecting cell meeting reselection conditions received in obtaining step S305; Continue to perform step S313: judge that whether the described synchronizing information treating re-selecting cell meeting reselection conditions is effectively complete, if then perform step S314, otherwise perform step S315.If what meet reselection conditions treats that re-selecting cell is also be recorded in treat re-selecting cell in band inter-sync demand schedule just, what namely meet band inter-sync condition treats re-selecting cell, so may have received this and treat the synchronizing information that re-selecting cell is part or all of in step S305, therefore, when needing after re-selecting cell meets reselection conditions, can the directly synchronous progress of obtaining step S305 and synchronized result, and judge accordingly mobile terminal whether completed with described meet reselection conditions treat the synchronous of re-selecting cell.
Step S314, the channel configuration of described mobile terminal release current area.Continue to perform step S318: reselect to from current area described meet reselection conditions treat re-selecting cell.
Step S315, the channel configuration of described mobile terminal release current area, continues the synchronizing information treating re-selecting cell described in receiving; Then step S317 is performed: judge that whether the described synchronizing information treating re-selecting cell meeting reselection conditions is effectively complete, if then perform step S318, otherwise perform step S319.
If the judged result of step S310 is no, then perform step S312: the channel configuration of described mobile terminal release current area, configures the described synchronizing channel treating re-selecting cell meeting reselection conditions; Continue to perform step S316: receive the described synchronizing information treating re-selecting cell meeting reselection conditions.Then step S317 is performed.
Step S318: described mobile terminal reselect to from current area described meet reselection conditions treat re-selecting cell.
Step S319, continues the synchronizing information treating re-selecting cell described in receiving, is then back to step S317.
At the mobile terminal of the present embodiment in the process of carrying out alien frequencies or isosystem measurement, synchronous treat that re-selecting cell is saved in band inter-sync demand schedule by needing to carry out, at each alien frequencies or in the isosystem measurement time period, obtain the synchronizing information treating re-selecting cell in described band inter-sync demand schedule, which save in cell reselection process and carry out the cell synchronous time, accelerate cell reselection speed, and reduce loss network side message volume probability.Maintain synchronous progress better by band inter-sync demand schedule and be easy to realize.
Further, what mass parameter is met reselection requirement treats that re-selecting cell is added in the interior demand schedule of band, adjust the time period of alien frequencies under described standby mode or isosystem measurement neatly according to the time of reception treating the synchronizing information of re-selecting cell recorded in band inter-sync demand schedule, be actually mass parameter meet reselection requirement treat that re-selecting cell is set to meet band inter-sync condition treat re-selecting cell.Like this, due to mass parameter meet reselection requirement treat that re-selecting cell is probably confirmed as meeting reselection conditions treat re-selecting cell, namely Target cell, therefore the probability that the synchronizing information completing Target cell within the time period of alien frequencies or isosystem measurement receives can be higher, after reselection evaluation, just can directly make described mobile terminal gravity treatment treat re-selecting cell to what meet reselection conditions, thus accelerate the process of described mobile terminal cell reselection further, decrease the probability losing network side message.
And, also do not complete when mobile terminal starts cell reselection with meet reselection conditions when re-selecting cell synchronous, describedly can meet on the basis for the treatment of the synchronizing information of re-selecting cell of reselection conditions what got, proceed synchronous, also can accelerate cell reselection process to a certain extent, and reduce the probability losing network side message.
