It is frequency point where user terminal current service cell with frequency, alien frequencies is the frequency point different from frequency point where user terminal current service cell.With the reselecting parameters of frequency and/or alien frequencies it can be understood that being the reselecting parameters of frequency point, and measure the frequency point where the neighboring community that the frequency point in list is user terminal current service cell.When the corresponding cell of frequency point, with the reselecting parameters of frequency and/or alien frequencies it can be appreciated that the reselecting parameters of the cell under each frequency point, that is, user terminal current service cell neighboring community reselecting parameters.
Wherein, the Reference Signal Received Quality thresholding of frequency point, Reference Signal Received Power thresholding, Signal to Interference plus Noise Ratio thresholding, line loss threshold, slow time etc. where which can include but is not limited to each neighboring community or each neighboring community.
It should be noted that the reselecting parameters for including in network server broadcast or the measurement list sent to user terminal can be the reselecting parameters of frequency point where the neighboring community of user terminal current service cell, such as table 1；Or the reselecting parameters of the neighboring community of user terminal current service cell, such as table 2；It can also be the reselecting parameters of neighboring community's belonging network standard of user terminal current service cell, such as 2G, 3G, 4G network system, such as table 3, the embodiment of the present invention is without limitation.

For ease of description, the reselecting parameters of frequency point where the embodiment of the present invention is mainly the neighboring community of user terminal current service cell with include in the measurement list carry out expansion explanation.
S202, user terminal support the cell under frequency point to carry out signal measurement the user terminal in measurement list, obtain the corresponding measurement parameter identical with reselecting parameters type of each cell.
In the embodiment of the present invention, user terminal is after the measurement list for getting the reselecting parameters including the adjacent affiliated frequency point of cell of cell locating for it, each cell under frequency point can be supported to carry out signal measurement user terminal in measurement list, to obtain the corresponding measurement parameter of each cell.Wherein, user terminal, which can be, carries out signal measurement to each cell under each frequency point according to the sequencing that frequency point arranges in measurement list, it is also possible to carry out signal measurement to each cell under each frequency point according to the sequence of the priority of frequency point, the embodiment of the present invention is without limitation.
Wherein, parameter type included by the corresponding measurement parameter of each cell is identical as parameter type included by the reselecting parameters of the affiliated frequency point of the cell.That is, when the reselecting parameters of a certain frequency point include the Reference Signal Received Quality thresholding, Reference Signal Received Power thresholding and Signal to Interference plus Noise Ratio thresholding of the frequency point, user terminal will be directed to signal receiving quality, signal reception power and Signal to Interference plus Noise Ratio, signal measurement is carried out to the cell under the frequency point, to obtain the corresponding signal receiving quality of each cell under the frequency point, signal reception power and Signal to Interference plus Noise Ratio.
For example, if include in the measurement list of network server broadcast is the reselecting parameters of the adjacent affiliated frequency point of each cell of cell locating for user terminal, its frequency point includes F1, F2, F3, F4, F5, and the frequency point that user terminal is supported is F2, F3, F5, F6, so user terminal will carry out signal measurement to the cell under frequency point F2, F3, F5 respectively after getting the measurement list.Assuming that the reselecting parameters of measurement list intermediate-frequeney point are Reference Signal Received Quality thresholding and Signal to Interference plus Noise Ratio, cell under F2 frequency point has cell2 and cell3, cell under F3 frequency point has cell4, and the cell under F5 frequency point has cell6 and cell7, so user terminal will to cell2, cell3, cell4, cell6, cell7, this five cells carry out signal measurement respectively
To obtain the measurement parameter of the corresponding signal receiving quality of each cell and Signal to Interference plus Noise Ratio.
From the cell that the user terminal supports under frequency point, the cell for choosing measurement parameter better than reselecting parameters forms Target cell set for S203, user terminal.
In the embodiment of the present invention, a certain cell of the user terminal in measurement list under its support frequency point carries out signal measurement, after obtaining the corresponding measurement parameter of the cell, the measurement parameter and the reselecting parameters of frequency point where the cell can be compared, if the measurement parameter is better than the reselecting parameters, just using the cell as the cell in Target cell set.
Wherein, when the reselecting parameters of the affiliated frequency point of a certain cell include Reference Signal Received Quality thresholding, Reference Signal Received Power thresholding and Signal to Interference plus Noise Ratio thresholding, the measurement parameter that user terminal obtain after signal measurement to the cell also includes signal receiving quality, signal reception power and the Signal to Interference plus Noise Ratio of the cell, therefore, measurement parameter is better than reselecting parameters it is to be understood that each parameter in measurement parameter is all larger than reselecting parameters；When the reselecting parameters of the affiliated frequency point of a certain cell include line loss threshold, the measurement parameter that user terminal obtain after signal measurement to the cell also includes the path loss of the cell, and therefore, measurement parameter is better than reselecting parameters it is to be understood that path loss is less than line loss threshold.
S204, user terminal are chosen first community from the Target cell set and are resident.
In the embodiment of the present invention, user terminal in measurement list its support the cell under frequency point to carry out signal measurement, and after selecting Target cell set, first community can be chosen from Target cell set and be resident.
Specifically, user terminal chosen from Target cell set first community carry out resident concrete mode can be with are as follows:
First community is randomly selected from Target cell set to be resident.That is, the probability that each cell is chosen by user terminal in Target cell set is identical, most users terminal can be prevented in this way while being resident to biggish cell is loaded, to reduce the load pressure of load large cell, realize the load balancing of each minizone.
It can be seen that, in the method depicted in fig. 2, user terminal is when carrying out cell reselection, signal measurement can be carried out to the cell supported under frequency point by the reselecting parameters in measurement list, to select the cell for meeting resident condition, first community is then chosen in these cells and is resident, can disperse the load pressure for loading large cell to a certain extent in this way, to improve the load balancing degrees of each minizone, the utilization rate of Internet resources is promoted.
Based on the network architecture shown in FIG. 1, the embodiment of the invention discloses another residence reselectings.Referring to Fig. 3, Fig. 3 is the flow diagram of another residence reselecting disclosed by the embodiments of the present invention.As shown in figure 3, the residence reselecting may comprise steps of:
S301, user terminal obtain measurement list from network server, which includes the reselecting parameters with frequency and/or alien frequencies.
S302, user terminal support the cell under frequency point to carry out signal measurement the user terminal in measurement list, obtain the corresponding measurement parameter identical with reselecting parameters type of each cell.
From the cell that the user terminal supports under frequency point, the cell for choosing measurement parameter better than reselecting parameters forms Target cell set for S303, user terminal.
S304, user terminal choose first community from the Target cell set according to preset order, and obtain the gravity treatment factor of the first community.
In the embodiment of the present invention, user terminal from choosing in measurement list after meeting the Target cell set of resident condition, the gravity treatment factor can be configured for each cell in Target cell set, the resident probability of success after the gravity treatment factor i.e. each cell are chosen by user terminal.Wherein, the sum of gravity treatment factor of all cells is 1 in Target cell set.
Therefore, after user terminal selects Target cell set in the cell under supporting frequency point from its in measurement list, understand and choose first community from the Target cell set according to preset order, while obtaining the gravity treatment factor of the first community from local.Wherein, the frequency point where which can be cell is measuring the sequencing in list, and the sequence of the priority of frequency point where being also possible to cell, the embodiment of the present invention is without limitation.
For example, assuming that user terminal cell from the Target cell set chosen in measurement list has cell4, cell5 and cell6, user terminal is that the gravity treatment factor of these three cells configuration is respectively 0.5,0.3 and 0.2, so when user terminal is chosen according to the sequencing of frequency point where cell in measurement list to cell6, it can obtain the gravity treatment factor of cell6 from local, as 0.2.
As a kind of feasible embodiment, the gravity treatment factor of cell is also possible to network server configuration.Network server includes the gravity treatment factor of each frequency point when broadcasting or sending measurement list, in measurement list, wherein the sum of gravity treatment factor of all frequency points is 1 in measurement list.It should be noted that the gravity treatment factor of the cell under each frequency point is the gravity treatment factor of the frequency point.Therefore, user terminal is according to preset order from target
After choosing first community in set of cells, the gravity treatment factor of frequency point where the first community being obtained from measurement list.
Again for example, the reselecting parameters of each frequency point of network server broadcast measure list such as table 1, and are the gravity treatment factor of each frequency point configuration, i.e., the gravity treatment factor of frequency point F1 is 0.6, and the gravity treatment factor of frequency point F2 is 0.4.When cell cell1, cell2, cell3 and the cell4 of user terminal in measurement list under its support frequency point F1 and F2 carry out signal measurement, the measurement parameter of cell cell2 and cell3 are better than the reselecting parameters of F1 and F2 respectively, therefore, user terminal chooses a cell cell2 in cell cell2 and cell3, then the gravity treatment factor that can obtain cell cell2 from measurement list is 0.6.
As another feasible embodiment, after measurement parameter is chosen in the cell under supporting frequency point from user terminal better than the cell composition Target cell set of reselecting parameters, and first community is being chosen from the Target cell set, and before obtaining the gravity treatment factor of the first community, user terminal can also configure the gravity treatment factor for each cell in Target cell set.Network server is that the mode of each frequency point configuration gravity treatment factor and user terminal are that each cell configuration mode of the gravity treatment factor is identical in Target cell set in measurement list.It is below that specific implementation can be with for each cell configures the gravity treatment factor in Target cell set by user terminal are as follows:
Mode one, under the premise of considering cell load, user terminal is that the concrete mode that each cell configures the gravity treatment factor in Target cell set may comprise steps of:
Step 11) user terminal is that each cell configures the average gravity treatment factor in Target cell set；
Step 12) user terminal from network server obtain Target cell set in each cell load information；
Step 13) user terminal chooses maximum load cell according to the load information from the Target cell set, and reduces the average gravity treatment factor of the maximum load cell, obtains the gravity treatment factor of the maximum load cell；
Step 14) user terminal increases the average gravity treatment factor of remaining cell in Target cell set in addition to the maximum load cell, obtains the gravity treatment factor of remaining cell.
In the specific implementation, user terminal after selecting Target cell set, can be that each cell configures the average gravity treatment factor according to the number of cells in Target cell set.Wherein, which is equal to the inverse of number of cells in the Target cell set.That is, the gravity treatment factor of each cell is identical in the Target cell set, and the sum of average gravity treatment factor of all cells is 1.
Further, network server can obtain the load information of each cell, user terminal in real time
From the load information for obtaining each cell in Target cell set in network server.Wherein, user terminal can obtain the payload size of each cell from the load information of each cell, so as to get maximum load cell.Due to it is initial when each cell the gravity treatment factor be the average gravity treatment factor, so user terminal is after getting maximum load cell, in order to avoid the load excessive of the maximum load cell, the average gravity treatment factor of the maximum load cell can be reduced, obtain the gravity treatment factor of maximum load cell.Wherein, the gravity treatment factor of the maximum load cell is less than the gravity treatment factor of any cell in remaining cell.In this way, user terminal is according to preset order after choosing first community in Target cell set, a possibility that maximum load cell is successfully resident by user terminal will reduce, and so as to effectively reduce the load pressure of maximum load cell, realize the load balancing of each minizone.
User terminal can be from the mode for obtaining the load information of each cell in Target cell set in network server, and network server will broadcast the load information of each cell at interval of a period of time to each user terminal；If reselecting parameters are the reselecting parameters of cell in network server broadcast or the measurement list sent, then network server can also carry the load information of each cell in the measurement list broadcasted or sent, the embodiment of the present invention is without limitation.
It should be noted that specifically reduction amount can determine that the embodiment of the present invention is without limitation to the average gravity treatment factor of maximum load cell in conjunction with the load difference between each cell in the loading level of the cell and the Target cell set.For example, the reduction amount of the average gravity treatment factor of the cell can be very big, or even the average gravity treatment factor of the cell is reduced to 0 if the load of remaining cell of the duty factor of a certain cell is much bigger in Target cell set.Wherein, maximum load cell may include the one or more cells for loading load in maximum one or more cells or Target cell set in Target cell set and being greater than default load, and the embodiment of the present invention is without limitation.
Further, while reducing the average gravity treatment factor of maximum load cell, user terminal can also adjust the average gravity treatment factor of remaining cell in Target cell set, to obtain the gravity treatment factor of remaining cell according to the gravity treatment factor of the maximum load cell after reduction.That is, user terminal need to suitably increase the average gravity treatment factor of remaining cell, so that the sum of the gravity treatment factor of all cells is always 1 in Target cell set after the average gravity treatment factor for reducing maximum load cell.
Optionally, after the average gravity treatment factor for reducing maximum load cell, user terminal, which can be, increases to the identical gravity treatment factor for the average gravity treatment factor of remaining cell, the degree for being also possible to the gravity treatment factor adjustment of each cell in remaining cell is different, but the gravity treatment factor of maximum load cell is in Target cell set
All cells in it is minimum.
For example, assuming that including 5 cells in Target cell set, the average gravity treatment factor of each cell is 0.2, so when user terminal selects maximum load cell in this 5 cells, the average gravity treatment factor of the maximum load cell can be decreased to 0.1, so the average gravity treatment factor of remaining 4 cell can be increased to 0.225 by user terminal, the average gravity treatment factor of remaining 4 cell can also be adjusted to 0.2,0.2,0.25,0.25 respectively.
Mode two, under the premise of considering the relationship of subdistrict frequency point and user terminal history persistent district frequency point, user terminal be in Target cell set each cell configure the gravity treatment factor concrete mode can with the following steps are included:
Step 21) user terminal is that each cell configures the average gravity treatment factor in Target cell set；
Step 22) user terminal identifies the Target cell different from user terminal history persistent district from Target cell set, and increases the average gravity treatment factor of the Target cell, obtains the gravity treatment factor of the Target cell；
Step 23) user terminal reduces the average gravity treatment factor of remaining cell in the Target cell set in addition to the Target cell, obtains the gravity treatment factor of remaining cell.
In the specific implementation, user terminal can recorde the frequency point of its history persistent district when progress cell is resident.Therefore, user terminal is after selecting Target cell set, it can be according to the frequency point of the history persistent district of its record, the Target cell different from history persistent district is identified from Target cell set, that is, the frequency point of the Target cell is different from the frequency point of user terminal history persistent district.So user terminal is on the basis of the gravity treatment factor of each cell is the average gravity treatment factor in Target cell set, the average gravity treatment factor of Target cell can be increased, the gravity treatment factor of the Target cell is obtained, and reduces the average gravity treatment factor of remaining cell, obtains the gravity treatment factor of remaining cell.Wherein, it must be 1 that the gravity treatment factor of Target cell, which is greater than the sum of the gravity treatment factor of any cell in remaining cell, and gravity treatment factor of the gravity treatment factor of Target cell and remaining cell,.
It should be noted that the frequency point of Target cell is different from the frequency point of user terminal history persistent district, it is possible to understand that are as follows: the frequency point of Target cell is that user terminal supports the frequency point not being resident before in frequency point.
Optionally, user terminal can also identify the newly-increased frequency point of network, if there is the cell under newly-increased frequency point in Target cell set, so user terminal can also increase the gravity treatment factor of the cell, so that user terminal is when the cell is arrived in selection, the success rate being resident to the cell is larger, to realize the load balancing of each minizone to a certain extent.
In this way, user terminal is according to preset order after choosing first community in Target cell set, when the Target cells different from user terminal history persistent district are got in choosing, a possibility that Target cell is successfully resident by user terminal just will increase, and for each user terminal, the cell different from its history persistent district also can be different, so as to effectively improve the load balancing degrees of each minizone.
For example, the frequency point of its history persistent district of user terminal record has F3 and F4, and the frequency point that user terminal is supported includes F2, F3, F4, F5, and in the measurement list of network server broadcast includes the reselecting parameters of F1, F2, F3, F4, F6, F7 frequency point.Therefore, user terminal can carry out signal measurement for the cell under F2, F3, F4 frequency point in measurement list, it is assumed that the cell under F2 frequency point has cell2 and cell3, and the cell under F3 frequency point has cell4, and the cell under F4 frequency point has cell5.So user terminal can carry out respectively signal measurement to cell2, cell3, cell4 and cell5 cell, obtain the corresponding measurement parameter of each cell.Assuming that the measurement parameter of cell2, cell3 and cell4 cell is better than its reselecting parameters for corresponding to frequency point respectively, then the cell that Target cell set includes just is cell2, cell3 and cell4.Therefore, the average gravity treatment factor equal 1/3 is configured when user terminal is initial for cell2, cell3 and cell4 cell.When user terminal identifies the frequency point difference of cell2 and cell3 cell and its history persistent district, the average gravity treatment factor of cell2 and cell3 cell will be increased to 0.4 by user terminal, and therefore, it is 0.2 that the average gravity treatment factor of cell4 cell, which is reduced by,.Certainly, the average gravity treatment factor that the average gravity treatment factor of cell2 cell is increased to 0.5, cell3 cell can also be increased to 0.4 by user terminal, then it is 0.1 that the average gravity treatment factor of cell4 cell, which is reduced by,.
Mode three, under the premise of considering native region priority, user terminal be in Target cell set each cell configure the gravity treatment factor concrete mode can with the following steps are included:
Step 31) user terminal is that each cell configures the average gravity treatment factor in Target cell set；
Step 32) user terminal chooses highest priority cell from Target cell set, and increases the average gravity treatment factor of the highest priority cell, obtains the gravity treatment factor of the highest priority cell；
Step 33) user terminal reduces the average gravity treatment factor of remaining cell in the Target cell set in addition to the highest priority cell, obtains the gravity treatment factor of remaining cell.
In the specific implementation, network server can broadcast or send simultaneously the priority of each frequency point when broadcasting or sending measurement list.Therefore, user terminal can select highest priority cell according to priority after selecting Target cell set in its cell under supporting frequency point from Target cell set.So user terminal can suitably increase the average gravity treatment factor of highest priority cell, obtain the gravity treatment of the highest priority cell on the basis of gravity treatment factor of each cell is the average gravity treatment factor in Target cell set
The factor, and reduce the average gravity treatment factor of remaining cell, obtain the gravity treatment factor of remaining cell.Wherein, it must be 1 that the gravity treatment factor of highest priority cell, which is greater than the sum of the gravity treatment factor of any cell in remaining cell, and gravity treatment factor of the gravity treatment factor of highest priority cell and remaining cell,.
In this way, user terminal is according to preset order after choosing first community in Target cell set, when highest priority cell is got in choosing, a possibility that highest priority cell is successfully resident by user terminal will be bigger than remaining cell, it in this way can be under the premise of guaranteeing that probability relative equilibrium is resident in each minizone, greatest priority principle is deferred to, to realize the load balancing of each minizone to a certain extent.
It should be noted that, user terminal each cell in for Target cell set configures after the average gravity treatment factor, it may be considered that the average gravity treatment factor of any one or a few in cell load, the relationship of subdistrict frequency point and user terminal history persistent district frequency point and native region priority because usually adjusting each cell in Target cell set.
Wherein, according to the average gravity treatment of each cell in multifactor adjustment Target cell set, because of the period of the day from 11 p.m. to 1 a.m, cell load can be paid the utmost attention to, that is to say, that when loading the priority also highest of maximum cell, the average gravity treatment factor of the cell can be reduced.
Mode four, under the premise of considering three factor of relationship and native region priority of cell load, subdistrict frequency point and user terminal history persistent district frequency point at the same time, user terminal be in Target cell set each cell configure the gravity treatment factor concrete mode can with the following steps are included:
Step 41) user terminal is that each cell configures the average gravity treatment factor in Target cell set；
Step 42) user terminal from network server obtain Target cell set in each cell load information；
Step 43) user terminal chooses maximum load cell according to the load information from the Target cell set, and reduces the average gravity treatment factor of the maximum load cell, obtains the gravity treatment factor of the maximum load cell；
Step 44) user terminal identifies the Target cell different for user terminal history persistent district from Target cell set, and increases the average gravity treatment factor of the Target cell, obtains the gravity treatment factor of the Target cell；
Step 45) user terminal chooses highest priority cell from Target cell set, and increases the average gravity treatment factor of the highest priority cell, obtains the gravity treatment factor of the highest priority cell；
Step 46) user terminal is according to the gravity treatment factor of the gravity treatment factor of maximum load cell, the gravity treatment factor of Target cell and highest priority cell, the average gravity treatment factor for adjusting remaining cell in Target cell set in addition to maximum load cell, Target cell and highest priority cell, obtains the weight of remaining cell
Select the factor.
In specific implementation, user terminal each cell in for Target cell set configures after the average gravity treatment factor, it can reduce the average gravity treatment factor of the average gravity treatment factor of maximum load cell, the increase Target cell different from user terminal history persistent district and increase the average gravity treatment factor of highest priority cell, then the average gravity treatment factor for adjusting remaining cell again, obtains the gravity treatment factor of remaining cell.In average gravity treatment factor Target cell set adjusted, the gravity treatment factor of maximum load cell is minimum, and highest priority cell and the gravity treatment factor of Target cell are comparatively bigger than the gravity treatment factor of remaining cell.After user terminal chooses first community from Target cell set according to preset order, a possibility that maximum load cell is successfully resident by user terminal is smaller, and Target cell and highest priority cell a possibility that being successfully resident by user terminal, is larger, each cell is more evenly dispersed into so as to load, the load balancing of each minizone is improved, to promote the utilization rate of Internet resources.
It should be noted that the sum of the gravity treatment factor of maximum load cell adjusted, the gravity treatment factor of Target cell, the gravity treatment factor of highest priority cell and gravity treatment factor of remaining cell are still 1.
Wherein, when the highest priority of maximum load cell, or when maximum load cell and user terminal history persistent district difference, the average gravity treatment factor of the maximum load cell is mainly reduced, and highest priority cell and Target cell can be chosen from remaining cell in Target cell set in addition to the maximum load cell.
For example, assuming that the cell for including in Target cell set is respectively cell2, cell3, cell4, cell5 and cell6, so user terminal first can configure the average gravity treatment factor for the gravity treatment factor of cell each in Target cell set, i.e., the gravity treatment factor of each cell is 0.2.When the cell in Target cell set is ordered from large to small by user terminal according to load, respectively 6 > cell of cell, 3 > cell, 4 > cell, 2 > cell 5, according to the sequence arrangement of priority from high to low, respectively 6 > cell of cell, 2 > cell, 3 > cell, 5 > cell 4, and when identifying that the cell different from user terminal history persistent district is cell 3, the available maximum load cell of user terminal is cell 6, highest priority cell is then chosen from the cell in addition to cell 6, as cell2.Therefore, the average gravity treatment factor of 6 cell of cell can be decreased to 0.08 by user terminal, the average gravity treatment factor of 2 cell of cell is increased to 0.3, and the average gravity treatment factor of 3 cell of cell is increased to 0.28, then the gravity treatment factor of 5 cell of 4 cell of cell and cell can be decreased to 0.17 simultaneously.
S305, user terminal generate a random number for the first community, and judge whether the random number is less than or equal to the gravity treatment factor, if so, executing step S306.
In the embodiment of the present invention, after getting the gravity treatment factor of the cell, user terminal can generate a number (i.e. random number) at random in 0~1 digital scope, user terminal can be made after choosing first community in Target cell set, can't to be directly resident to the first community according to preset order in this way.That is, user terminal after choosing a certain cell, be resident it is consistent with the gravity treatment factor of the cell to the success rate of the cell, to realize the load balancing of each minizone.
Specifically, user terminal may determine that whether the random number is less than or equal to the gravity treatment factor of the first community when generating a random number for the first community, if it is less than or be equal to the gravity treatment factor, user terminal is just resident to the first community；If it is greater than the gravity treatment factor, user terminal can choose second community from Target cell set again according to preset order, and obtain the gravity treatment factor of the second community, then a random number is generated again for the second community, and compare the size of the random number and the gravity treatment factor of the second community, until being successfully resident a certain cell into Target cell set.
S306, user terminal are resident to the first community, and terminate this process.
In the embodiment of the present invention, when judge user terminal generate random number be less than or equal to the first community gravity treatment because of the period of the day from 11 p.m. to 1 a.m, user terminal can be resident to the first community.
It can be seen that, in the method depicted in fig. 3, user terminal is when carrying out cell reselection, the gravity treatment factor can be configured for each cell, when user terminal chooses a cell in the Target cell set for meeting resident condition according to preset order, the success rate that each cell is resident by user terminal is identical as the gravity treatment factor configured for each cell, and the load of each minizone promotes network resource utilization to reach balanced to a certain extent.
Based on the network architecture shown in FIG. 1, the embodiment of the invention discloses another residence reselectings.Referring to Fig. 4, Fig. 4 is the flow diagram of another residence reselecting disclosed by the embodiments of the present invention.As shown in figure 4, the residence reselecting may comprise steps of:
S401, user terminal obtain measurement list from network server, which includes the reselecting parameters with frequency and/or alien frequencies.
S402, user terminal support the cell under frequency point to carry out signal measurement the user terminal in measurement list, obtain the corresponding measurement parameter identical with reselecting parameters type of each cell.
From the cell that the user terminal supports under frequency point, the cell for choosing measurement parameter better than reselecting parameters forms Target cell set for S403, user terminal.
S404, user terminal choose first community from the Target cell set according to preset order, and obtain the gravity treatment factor of the first community.
S405, user terminal generate a random number for the first community, and judge whether the random number is less than or equal to the gravity treatment factor, if so, executing step S407；If it is not, executing step S406.
In the embodiment of the present invention, when gravity treatment of the random number that user terminal generates less than or equal to the first community is because of the period of the day from 11 p.m. to 1 a.m, user terminal can be directly resident to the first community；When gravity treatment of the random number that user terminal generates greater than the cell is because of the period of the day from 11 p.m. to 1 a.m, user terminal can further obtain the selection number for choosing cell from Target cell set according to preset order.
S406, user terminal obtain the selection number for choosing cell from Target cell set according to preset order, and judge whether the selection number is less than default choose and controls number, if so, executing step S404；If it is not, executing step S407.
In the embodiment of the present invention, user terminal can not successfully be resident the cell into Target cell set for a long time in order to prevent, can introduce it is default choose control number, i.e. the user terminal maximum number of operations of choosing cell from Target cell set according to preset order.Therefore, user terminal will record the selection number for choosing cell when choosing cell from Target cell set according to preset order.Wherein, which can be what user terminal was set based on experience value, be also possible to network server according to the number of cells setting that can be able to satisfy the resident condition of user terminal in measurement list, the embodiment of the present invention is without limitation.Wherein, occurs the critical value that gravity treatment table tennis is obtained with movement speed corresponding when not occurring gravity treatment table tennis when which specifically can be user terminal by carrying out cell reselection in the past.
Therefore, when gravity treatment of the random number of user terminal generation greater than the cell is because of the period of the day from 11 p.m. to 1 a.m, user terminal can obtain the selection number for choosing cell, and judge whether the selection number is less than default choose and controls number.
Further, when choosing number less than default selection control number, user terminal will choose second community from Target cell set again according to preset order；And when choosing number equal to default selection control number, user terminal is just directly resident to the first community.
For example, assuming that the cell in Target cell set has 6, and default control number of choosing is set as 5, so when user terminal chooses cell from Target cell set according to the sequence of measurement list, if chosen to the 5th cell, even when the random number that user terminal generates is greater than the gravity treatment factor of the cell, user terminal also can be directly resident to the cell.
S407, user terminal are resident to the first community.
In the embodiment of the present invention, it is less than or equal to the gravity treatment of the first community because of the period of the day from 11 p.m. to 1 a.m in the random number that user terminal generates, or the random number generated in user terminal is greater than the gravity treatment factor of the first community, and when choosing the selection number of cell from Target cell set according to preset order equal to default selection control number, user terminal can be directly resident to the first community.
It can be seen that, in the method described in Fig. 4, user terminal is when carrying out cell reselection, it can be when the selection number for choosing cell be equal to default selection control number, directly it is resident to the cell, the case where can preventing user terminal that can not be resident to cell for a long time in this way generation, so that user terminal can be resident faster to the cell for meeting resident condition.
Based on the network architecture shown in FIG. 1, the embodiment of the invention discloses another residence reselectings.Referring to Fig. 5, Fig. 5 is the flow diagram of another residence reselecting disclosed by the embodiments of the present invention.As shown in figure 5, the residence reselecting may comprise steps of:
S501, user terminal detect the movement speed of the user terminal, and judge whether the movement speed is less than or equal to default movement speed threshold value, if so, executing step S502；If it is not, terminating this process.
In the embodiment of the present invention, if user terminal gets the measurement list broadcasted by network server or sent, user terminal just must carry out cell reselection according to the reselecting parameters in measurement list.And if user terminal gets the measurement list broadcasted by network server or sent in continuous moving process, even if each parameter of the current persistent district of user terminal is all satisfied resident condition, user terminal equally also can constantly carry out cell reselection, user terminal may just be will appear so constantly to toggle between the cell of each frequency point, to increase the power consumption of user terminal.
Therefore, user terminal if detecting that itself is in moving condition, obtains the movement speed of itself, and judges whether the movement speed is less than or equal to default movement speed threshold value before obtaining measurement list from network server.Wherein, user terminal can be positioned so that by positioning device detects its movement speed.
