Description
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a cell selection method, apparatus, device, and computer readable storage medium.
Background
In the related art, a terminal considers only reference signal reception power of a cell when performing cell selection. For example, after searching for a plurality of cells, the terminal ranks the reference signal received powers of the plurality of cells in order from large to small, and selects a cell residence with the largest reference signal received power according to the ranking.
In many cases, however, the reference signal received power does not accurately characterize the network quality of a cell. For example, when the size of the resource block allocated by the network to the cell is small, even if the reference signal receiving power of the cell is large, the problem of network blocking of the terminal still can be caused, and bad use experience is brought to the user.
Therefore, the related art selects cell camping using the reference signal received power, and does not enable the terminal to actually select a cell with the highest communication quality.

Fig. 1 is a schematic flow chart of a cell selection method, which may be performed by a terminal, shown in accordance with an embodiment of the present disclosure. The terminal comprises, but is not limited to, a mobile phone, a tablet computer, wearable equipment, a sensor, internet of things equipment and other communication devices.
As shown in fig. 1, the cell selection method includes:
in step S101, at least one cell to be selected is determined;
in step S102, determining a service affecting parameter of a cell to be selected, where the service affecting parameter is used to characterize a possibility that a terminal performs service abnormality in the cell to be selected;
in step S103, it is determined, at least in accordance with the service affecting parameters, that a cell is camping in at least one cell to be selected.
It should be noted that the embodiment shown in fig. 1 may be implemented independently or in combination with at least one other embodiment in the disclosure, and the disclosure is not limited thereto.
In one embodiment, the terminal may perform cell selection and/or cell reselection and may determine at least one cell to select after the frequency sweep. Wherein the sweep frequency comprises at least one of: and (3) system frequency sweep and full-band frequency sweep.
For example, the terminal may perform a system scan, after determining a plurality of frequency points through the system scan, the plurality of frequency points may be ordered according to a frequency priority (e.g., may be agreed by a protocol or configured for a network device), and then determine a cell to be selected from cells corresponding to the frequency points according to the priority from high to low.
The terminal is provided with a database locally, and the frequency points of the cells which are scanned and/or connected in history are stored in the database. When the terminal scans the system, the frequency points of the cells stored in the database can be scanned preferentially. If the cells meeting the connection requirements are not obtained through system scanning, the terminal can carry out full band scan (full band scan), namely the terminal can carry out the frequency scanning according to all the supported frequency bands, after the scanned frequency points are ordered, the cells to be selected are determined in the cells corresponding to the frequency points, and the cells where the terminal resides are determined from the cells to be selected.
In one embodiment, when the terminal determines only one cell to be selected, the terminal may select the cell as a camping cell, and when the terminal scans a plurality of cells to be selected, the terminal may sort the plurality of cells to be selected according to some rules (for example, R criteria, S criteria, which are not described in detail herein) for selecting the camping cell, and determine the camping cell from high to low according to the order of cell sorting.
In one embodiment, the related art ranks cells generally only with respect to reference signal received power (Reference Singal Receiving Power, RSRP), however, RSRP is not the only factor that measures the communication quality of terminals in a cell.
When a terminal communicates in a cell, although RSRP can represent the signal strength of the cell, it cannot accurately represent the communication quality of the terminal in the cell. For example, when a network abnormality occurs, the cell may discard data, so that the user obviously perceives a problem of network blocking of the terminal, but the problem of discarding data of the cell cannot be reflected by RSRP. Therefore, the service influence parameter characterizes the possibility of abnormality of the terminal when the terminal performs the service in the cell, and the cell to be selected by the terminal can be determined from the possibility of abnormality of the service of the terminal in the cell.
In one embodiment, in addition to storing the scanned and/or connected cell information in the database local to the terminal, the service impact parameters corresponding to the stored cell information may also be stored in the database.
The terminal can determine the possibility of abnormality when the terminal performs the service in any cell by inquiring the service influence parameters stored correspondingly by the information of the cell in the database. Thereby determining a service impact parameter corresponding to at least one cell to be selected.
In one embodiment, the service impact parameter is used to characterize the possibility of abnormal service occurrence of the terminal in the cell to be selected. For example, the traffic impact parameters of the cells to be selected may be determined by counting the number of times the terminal historically experiences an abnormality in traffic in the cells to be selected. The higher the probability of abnormal traffic of the terminal in the cell, which is characterized by the traffic influencing parameter, the lower the communication quality of the terminal in the cell, and the cell should be of lower priority when the terminal selects the cell for residence.
In one embodiment, a cell is determined to camp on in at least one cell to be selected based at least on a traffic affecting parameter. Since the traffic influencing parameters are able to characterize the possibility of a terminal to experience traffic anomalies in the cell, it is possible to determine the cell in which the terminal is selected to camp at least on the basis of the traffic influencing parameters.
In one embodiment, the terminal may calculate the service impact parameter of the cell to be selected to determine the cell to be selected with the highest priority as the cell to be camped on.
In one embodiment, the terminal may camp on a cell according to the service parameters and conduct service communications in the cell. After selecting a cell, the terminal performs service communication in the cell. And under the condition that the service parameter of the resident cell is less in possibility of service abnormality, the terminal is indicated to be more stable in service communication in the cell.
According to the method and the device, the business influence parameters of at least one cell to be selected are determined, and the resident cell is determined based on the possibility of abnormality of the terminal in the cell to be selected, so that the terminal pays attention to the possibility of abnormality of the business of the terminal in the cell in cell selection, the probability of abnormality of the business of the terminal in the resident cell is lower than that of the terminal in other cells, business communication is more stable, the terminal is smoother in the process of carrying out network communication, no jamming occurs, and the occurrence of business abnormality is less.
In one embodiment, the at least one cell to be selected may comprise: a first cell in the database determined by the system scan, and a second cell not stored in the database determined by the full band scan. After determining the first cell stored in the database, the service impact parameter corresponding to the first cell stored in the database may also be determined.
In one embodiment, the at least one cell to be selected comprises at least one of: a first cell in which a terminal has acquired a service affecting parameter; and the terminal does not acquire the second cell of the service influence parameters.
The terminal can determine the first cell and the service influence parameters corresponding to the cell according to the information in the stored database. It should be noted that, the database may store only the information of the first cell, but not the service affecting parameter corresponding to the first cell, so that the first cell in this portion may be identified as the second cell that does not acquire the service affecting parameter, or the service affecting parameter of the first cell in this portion may be identified as 0, that is, it is identified that the first cell in this portion has not been abnormal in the process of performing the service so far, and identifying the service affecting parameter as 0 may also indicate that the possibility of performing the service in this portion has been 0 so far.
In one embodiment, the terminal may also determine the service impact parameter corresponding to the first cell by scanning, and receiving the service impact parameter of the determined cell sent by the network when determining the information of the cell through scanning.
In one embodiment, determining the traffic affecting parameters of the cell to be selected comprises: and if the cell to be selected is the first cell, determining the acquired business influence parameter of the first cell as the business influence parameter of the cell to be selected.
In one embodiment, determining the traffic affecting parameters of the cell to be selected comprises: and if the cell to be selected is the second cell, determining that the business influence parameter of the cell to be selected is 0.
Fig. 2 is a schematic flow chart illustrating one method of determining cell traffic impact parameters according to an embodiment of the present disclosure. As shown in fig. 2, determining the service impact parameters of the cell to be selected includes:
in step S201, if the cell to be selected is the first cell, determining the acquired service affecting parameter of the first cell as the service affecting parameter of the cell to be selected;
in step S202, if the cell to be selected is the second cell, it is determined that the service affecting parameter of the cell to be selected is 0.
It should be noted that the embodiment shown in fig. 2 may be implemented independently or in combination with at least one other embodiment in the disclosure, which is not limited in this respect.
In one embodiment, if the cell to be selected is the first cell, the determined service affecting parameter of the first cell is used as the service affecting parameter of the cell to be selected.
And if at least one cell to be selected is scanned by the terminal when the terminal scans the cells, and a part of the cells are first cells capable of determining the business influence parameters, the business influence parameters of the first cells are used as the business influence parameters of the part of the cells to be selected.
In one embodiment, if the cell to be selected is the second cell, the service impact parameter of the cell to be selected is determined to be 0.
If the terminal scans the cells, and another part of the scanned cells are second cells (which can be the cells only storing the information of the cells but not storing the corresponding business influence parameters of the cells in the database or the new cells which are not stored in the database and scanned for the first time) which cannot determine the business influence parameters of the second cells, determining the business influence parameters of the second cells as 0, and taking the business influence parameters of the second cells as the business influence parameters of the cells which cannot determine the business influence parameters of the other part of the cells to be selected.
By determining the service influence parameters corresponding to any one of the at least one cell to be selected, the terminal can rank the possibility of the at least one cell to be selected for the occurrence of service abnormality in the cell from low to high according to the service influence parameters, and select the cell residence with the lowest possibility of the occurrence of service abnormality.
In one embodiment, the cell selection method further comprises: when the terminal resides in the first cell, the service affecting parameters of the first cell are recorded.
After the terminal determines the cell to be resided in at least one cell to be selected according to the service influence parameters, if the cell is a second cell which is not stored in the database previously, the information of the cell is stored in the database, the cell is changed into a first cell, and the number of network abnormality times occurring in the cell is recorded to be used as the service influence parameters. When the cell where the terminal resides is selected as the first cell, the terminal can record the number of network anomalies occurring in the first cell, and further record the business influence parameters of the first cell in a database, so that the first cell can be searched from the database quickly and conveniently through system scanning next time, and the business influence parameters of the first cell in the cells to be selected can be quickly and conveniently determined according to the business influence parameters of the first cell recorded in the database.
In one embodiment, the cell selection method further comprises: and deleting the service influence parameters of the first cell when the effective time of the service influence parameters of the first cell is expired.
Since the terminal may pass through more geographic areas, more first cells may be searched and stored, and if all the first cells and corresponding service influence parameters are stored, excessive storage space may be occupied due to more data and larger data volume. Therefore, for the service affecting parameters of the first cells stored in the terminal, the effective time can be preset, and when the effective time of the service affecting parameter of any first cell is out of date, the service affecting parameter of the first cell is deleted, so as to reduce the occupied space. On the other hand, the service influence parameters have certain timeliness, the reference value of the service influence parameters of the first cell before the long time in the process of selecting the cell later is smaller, so that the expired service influence parameters of the first cell are deleted in time, and the accuracy of the service influence parameters for representing the possibility of occurrence of service abnormality of the terminal in the cell is guaranteed.
In one embodiment, whether the service affecting parameter is out of date may be determined by determining a difference between the recorded time and the current time of the service affecting parameter of the first cell and comparing the difference with a preset valid time.
In an embodiment, the recorded service impact parameters may also be set, so that the service impact parameters corresponding to any first cell only store the set valid time in the database, so that the service impact parameters automatically fail after exceeding the preset valid time.
In one embodiment, when the validity time of the service affecting parameters of the first cell expires, all the service affecting parameters corresponding to the first cell may be deleted.
In one embodiment, the stored service affecting parameters of the first cell are a set of service affecting parameters, where any one service affecting parameter records a corresponding valid time, so that when the valid time of any one service affecting parameter expires, any expired service affecting parameter can be deleted, and the rest of unexpired service affecting parameters in the first cell are reserved.
In one embodiment, the business impact parameters used in the above embodiments of the present disclosure include at least one of the following: the first parameter is used for indicating the number of times of uplink data accumulation of the cell to be selected; a second parameter, which is used for indicating the number of times of data discarding of the cell to be selected; and a third parameter, configured to indicate the number of times that the resources allocated by the network are completely used up when the cell to be selected appears in the second preset time period.
The terminal can be used as a service influence parameter by the times of up data accumulation, data discarding and total use of resources allocated by the network within a second preset duration, and is used for measuring the possibility of abnormality when the terminal performs service in the cell. The larger the first parameter, the second parameter and the third parameter are, the greater the possibility that the terminal is abnormal when doing business in the cell is indicated.
The third parameter is used for indicating the number of times that the resources allocated by the network are completely used up when the cell to be selected appears in the second preset time period. For example, in the second preset duration of the cell, the situation that the network allocation is equal to the terminal use (grant size=byte building) continuously occurs, that is, it is indicated that all the resource terminals allocated in the network are used up in the second preset duration, so that the terminal is more likely to get stuck, and the experience of the user is greatly affected.
In one embodiment, the second preset time period may be 3 seconds.
In one embodiment, determining that a cell is camping in at least one cell to be selected based at least on the traffic affecting parameters comprises: and determining the cell to be selected for camping according to at least one of the first parameter, the second parameter and the third parameter.
For example, at least one parameter of the first parameter, the second parameter and the third parameter may be calculated, and one cell is selected from the cells to be selected to camp on according to the calculation result.
For example, the manner of calculation includes, but is not limited to: and (5) weighted summation.
For example, the above calculation result may be determined based on only the first parameter or the second parameter or the third parameter.
For another example, two parameters of the first parameter, the second parameter, and the third parameter may be weighted and summed to obtain the calculation result.
For another example, the first parameter, the second parameter, and the third parameter may be weighted and summed to obtain the calculation result.
Fig. 3 is a schematic flow chart diagram illustrating a cell selection method according to an embodiment of the present disclosure. As shown in fig. 3, determining that a cell is camping in at least one cell to be selected at least according to a service influence parameter includes:
in step S301, the first parameter, the second parameter, and the third parameter are weighted and summed;
in step S302, it is determined that the cell to be selected corresponding to the minimum value in the summation result resides.
It should be noted that the embodiment shown in fig. 3 may be implemented independently or in combination with at least one other embodiment in the disclosure, which is not limited in this respect.
How the first parameter, the second parameter, and the third parameter are weighted and summed, and the result of the summation is determined will be described in detail below.
Determining according to business influence parameters of each cell in the cells to be selected、/>、/>Wherein->For representing the first parameter (curbyte number of times that the uplink data is piled up is not 0),for representing the second parameter (number of times discard sum is not equal to 0, i.e. number of times data is discarded),>for the third parameter (grant size=byte building number, i.e. the number of times the network allocated resources are fully used up in the second preset period of time), for the above->、/>、/>The levels are determined separately, and by the determined levels, weighted summation is performed using the following formula (1).
Formula (1):
wherein, in the above formula,for the level determined on the basis of the first parameter +.>For the level determined on the basis of the second parameter +.>For a grade determined according to the third parameter. />、/>The weighting coefficients corresponding to the items can be flexibly set according to actual requirements. />The rank of the summation result is used to represent the residence priority order of the corresponding cell, and the smaller the rank of the summation result is, the earlier the residence priority order of the corresponding cell is.
It should be noted that in practice it is also possible to directly follow、/>、/>To perform the weighting calculation. The three are converted into the corresponding grades, so that the terminal operation can be facilitated, the operation speed is improved, and the calculation result is not affected substantially.
Wherein the above determination、/>、/>The value ranges and the corresponding levels in the levels can be freely set according to the requirements, and the disclosure is not limited to this, and the above formulas and levels are only examples.
In one embodiment, the weighting coefficients c > a, and c > b. In the process that the user uses the terminal, the third parameter can cause the service of the terminal in the cell to be obviously blocked, and the influence on the user experience is the greatest, so that more weight can be allocated to the third parameter, and the third parameter is preferably considered to be more important than the first parameter and the second parameter when the user selects to reside in the cell.
For example, a=0.1, b=0.2, c=0.3, c > a, and c > b.
In one embodiment, according toAnd sequencing at least one cell to be selected, and selecting the cell with the highest priority for residence.
In one embodiment, if the sum result determined by the service impact parameters of the plurality of cells to be selected is the same, one of the cells to be selected may be determined to be a camping cell according to the following manner: determining the effective time of the service influence parameters corresponding to the same summation result, and determining the cell to be selected with the longest effective time distance expiration time of the service influence parameters as a resident cell; or determining the business influence parameters corresponding to the same summation result, and selecting the cell residence to be selected with the minimum third parameter.
On the one hand, the longer the effective time distance of the business-affecting parameter expires, the more time-efficient the business-affecting parameter is, and the more valuable the reference value is. On the other hand, the influence of the third parameter has the greatest influence on the operation feeling of the user using the terminal, and thus the cell to be selected with the smallest third parameter is selected as the camping cell.

It should be noted that the embodiment shown in fig. 4 may be implemented independently or in combination with at least one other embodiment in the disclosure, which is not limited in this respect.
The RSRP of a cell determines the strength of a cell signal, and in general, the stronger the cell signal, the more stable the network connection. Thus, RSRP may be combined with the traffic influencing parameters proposed by the present disclosure, comprehensively considering how to determine the traffic influencing parameters.
In fact, this embodiment can be combined with any of the above embodiments. And calculating the reference signal strength of at least one cell to be selected and the possibility of occurrence of service abnormality through the RSRP and the service influence parameters, and comprehensively considering to determine the priority of the at least one cell to be selected so as to determine the resident cell.
In one embodiment, taking the above-mentioned service affecting parameters including the first parameter, the second parameter, and the third parameter as examples, the manner of determining the camping cell after combining with RSRP may be described as follows.
Wherein, the liquid crystal display device comprises a liquid crystal display device,the level of the RSRP of the cell is also used for facilitating the operation of the terminal.
Where d is a weighting coefficient of the RSRP level of the cell, for example d may be 1.
