Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of steps of a network searching method according to an embodiment of the present invention, as shown in fig. 1, where the method may be applied to a mobile terminal, and the method may include:
In the embodiment of the present invention, the network searching request may be sent to the mobile terminal by a user through triggering a network searching function of the mobile terminal, and the network searching request may be used to instruct the mobile terminal to perform network searching for registration, which is a CSFB call network searching, and the like. Specifically, the user may control the mobile terminal to start to trigger the network searching function, or may control the mobile terminal to perform network connection to trigger by clicking a network connection button of the mobile terminal, and of course, the user may also trigger in other manners, which is not limited in the embodiment of the present invention.
Further, the N candidate search frequency points may be frequency points whose signal quality is greater than a preset quality threshold in a permanent location point of the mobile terminal, where N is a positive integer, and a specific value of N may be preset, for example, N may be 20, and further, the permanent location point may be a location where the residence frequency meets a preset condition, where the preset condition may include: and the residence frequency is greater than at least one of the preset residence frequency threshold value and the residence time length is greater than the preset residence time length threshold value. In the embodiment of the invention, the frequency point with better signal quality in the resident place of the mobile terminal is taken as the searching frequency point to be selected, so that each searching frequency point to be selected can be ensured to have higher utilization value, and the reduction of the network searching efficiency can be further avoided.
Furthermore, with the influence of external factors, the signal quality of each frequency point to be searched and the use condition of the user for the frequency point to be searched may change, so that the utilization value of the frequency point to be searched may change, therefore, in order to ensure the success rate of network searching, in the embodiment of the invention, under the condition that the terminal receives the network searching request, the M preferential search frequency points can be selected from the search frequency points to be selected for network searching based on the network searching fitness of the search frequency points to be selected, and as an example, the network searching fitness of each searching frequency point to be selected can be calculated in sequence, the searching frequency point to be selected with the network searching fitness larger than a preset network searching fitness threshold value is selected as a preferential searching frequency point to ensure the network searching success rate, and M is a positive integer less than or equal to N, and the specific value of M can be the number of the to-be-selected search frequency points with the network searching fitness greater than a preset network searching fitness threshold.
And step 102, sequentially carrying out network searching operation based on the M preferential searching frequency points.
In the embodiment of the invention, the mobile terminal can sequentially perform network searching based on each priority searching frequency point until one of the priority searching frequency points is connected to the network, and then the network searching operation can be stopped.
In summary, in the network searching method provided in the embodiment of the present invention, in a case that a network searching request is received, a mobile terminal selects M preferential search frequency points from N search frequency points to be selected based on preset network searching fitness of the N search frequency points to be selected, and then sequentially performs network searching operations based on the M preferential search frequency points, where the search frequency points to be selected are frequency points whose signal quality is greater than a preset quality threshold in a permanent location point of the mobile terminal. In the embodiment of the invention, the frequency point with better signal quality in the resident place of the mobile terminal is taken as the searching frequency point to be selected, so that the problems of lower utilization value of the frequency point and reduction of network searching efficiency can be avoided, and meanwhile, M preferential searching frequency points are selected from the N searching frequency points to be selected for network searching based on the network searching fitness, thereby ensuring that the frequency points are connected to the network with higher probability and improving the success rate of network searching.
Fig. 2 is a flowchart of steps of another network searching method according to an embodiment of the present invention, as shown in fig. 2, where the method may be applied to a mobile terminal, and the method may include:
In this step, the historical usage parameter of the candidate search frequency point may include a historical connection frequency or a historical connection duration for the mobile terminal to connect to the network using the candidate search frequency point, and the Signal Quality of the candidate search frequency point may be Signal Strength (Reference Signal Receiving Power, RSRP), Signal Receiving Quality (Reference Signal Receiving Quality, RSRQ), Signal-to-Noise Ratio (SNR), or Received Signal Strength Indication (RSSI). Specifically, when the mobile terminal acquires the signal quality of the to-be-selected search frequency point, the signal quality of the to-be-selected search frequency point can be determined through real-time detection, and of course, the mobile terminal can also periodically detect and store the signal quality of the to-be-selected search frequency point, so that the mobile terminal can determine the signal quality of the to-be-selected search frequency point in a reading mode. Further, when obtaining the historical use parameters of the to-be-selected search frequency point, the mobile terminal may obtain the historical connection times or the historical connection duration for connecting the network by using the to-be-selected search frequency point from the historical connection record, and accordingly, in practical application, the mobile terminal may update the historical connection times and the historical connection duration for connecting the to-be-selected search frequency point to the network after connecting the network based on the to-be-selected search frequency point each time.
In this step, the fitness of the to-be-selected search frequency point may be in direct proportion to the signal quality of the to-be-selected search frequency point and the historical use parameter, so that the fitness of the to-be-selected search frequency point may reflect the utilization value of the to-be-selected search frequency point, and it may be further ensured that a preferred search frequency point with a higher bid value may be selected based on the search network fitness.
Furthermore, the network searching fitness of the to-be-selected searching frequency point is calculated based on the signal quality and the historical use parameters, so that the utilization value of the to-be-selected searching frequency point can be accurately reflected by the calculated network searching fitness, and therefore, when the network searching is carried out on the preferential searching frequency point selected based on the network searching fitness, the network can be connected to the network with higher probability, and the success rate of network searching is improved.
Specifically, when calculating the network searching fitness, the mobile terminal may calculate the network searching fitness of the to-be-selected search frequency point according to the following formula (1):
wherein, alpha represents the network searching fitness, R represents the signal quality, T represents the historical use parameter, A1For a first preset regulation parameter, B1For a second preset control parameter, C1For a third preset control parameter, D1For the fourth preset control parameter, E1For a fifth preset adjustment parameter, A1、B1、C1、D1And E1The specific value of (A) can be pre-selected according to actual requirements, and is exemplified by1Can be 120, B1Can be 100, C1Can be 1, D1Can be 2, E1May be 0.5 as A1Is 120, B1Is 100, C1Is 1, D1Is 2, E1For the 0.5 example, the first part of this equation (1) represents the net search fitness component of signal quality, and typically, the common real net range for R is [ -70dbm, -120dbm]Thus, the range of the first portion is typically [0, 0.5]]The second part of the equation (1) is the net searching fitness component of the historical use parameter, and T may range from [1, infinity), so the range of the second part is generally between [0.25, 0.5), and the net searching fitness of the second part increases less as the historical use parameter increases. Because the difference between the magnitude of R and the magnitude of T is larger, in the embodiment of the invention, the network searching fitness can be calculated by using the formula (1), and the magnitude difference between R and T is eliminated by adjusting the coefficient, so that the R and T can be ensured to make corresponding contribution to the network searching fitness, the calculated network searching fitness is more representative, and the utilization value of the network searching frequency point to be selected can be reflected more reasonably and truly.
Further, in practical application, the signal quality of the to-be-selected search frequency point at the corresponding resident location is optimal, so that the closer the position of the mobile terminal is to the resident location corresponding to the to-be-selected search frequency point, the better the success rate of the mobile terminal in connecting the network and the quality of network connection based on the to-be-selected search frequency point are, therefore, in the embodiment of the present invention, when the network searching adaptability is calculated, the mobile terminal may further obtain the distance between the current position of the mobile terminal and the resident location corresponding to the to-be-selected search frequency point, and then calculate the network searching adaptability of the to-be-selected search frequency point according to the following formula (2):
wherein R is the signal quality, T is the historical usage parameter, S is the distance, a2 is a sixth preset tuning parameter, B2 is a seventh preset tuning parameter, C2 is an eighth preset tuning parameter, D2 is a ninth preset tuning parameter, E2 is a tenth preset tuning parameter, F is a preset distance coefficient, the specific values of a2, B2, C2, D2, E2 and F may be pre-selected according to actual requirements, for example, a2 may be 120, B2 may be 100, C2 may be 1, D2 may be 2, E2 may be 0.5, F may be any one of the numerical ranges [ -1, 0], correspondingly, a2 is 120, B2 is 100, C2 is 1, D2 is 2, E2 is 0.5, the first portion of the formula (2) represents the first portion of the signal quality, S represents the general net component of the real net-degree R70, the real net-degree range of the db [ -70, R70, the net-degree of the general net-degree of the first portion of the formula (2), therefore, the range of the first part is generally between [0, 0.5], the range of the formula (2) is a network searching fitness component of the historical use parameter, the range of T may be [1, infinity), and therefore, the range of the second part is generally between [0.25, 0.5), and as the historical use parameter increases, the increase of the network searching fitness brought by the second part decreases, and the range of the formula (2) is a network searching fitness component of the distance, and the closer the distance between the permanent site corresponding to the to-be-selected search frequency point and the current position of the mobile terminal is, the greater the network searching fitness of the to-be-selected search frequency point is.
In the embodiment of the invention, the network searching fitness is calculated by using the formula (2), the order difference between R and T can be eliminated by adjusting the coefficient, so that the R and T can make corresponding contribution to the network searching fitness, the calculated network searching fitness is more representative, the utilization value of the network searching frequency point to be selected can be reflected more reasonably and truly, and meanwhile, a distance factor is added in the process of calculating the network searching fitness, so that when a preferential searching frequency point is selected based on the network searching fitness in the subsequent step, the closer distance can be selected with higher probability, the preferential searching frequency point with higher value is utilized, and the probability of connecting to a network based on the preferential searching frequency point and the quality of the connected network can be improved.
And 203, selecting M preferential search frequency points from the N search frequency points to be selected based on preset network searching fitness of the N search frequency points to be selected.
In this step, the mobile terminal may determine, as the preferred search frequency point, the to-be-selected search frequency point whose network searching fitness is greater than the preset network searching fitness threshold, where the preset network searching fitness threshold may be set according to an actual situation, and the embodiment of the present invention does not limit this. Of course, the mobile terminal may also select the frequency points based on other manners, for example, taking the network searching fitness of each frequency point to be selected as the selection probability, and then selecting a preset number of frequency points to be selected. In the embodiment of the invention, the to-be-selected searching frequency point with the network searching adaptability degree larger than the preset network searching adaptability degree threshold is selected as the prior network searching frequency point, so that the higher utilization value of the prior network searching frequency point for performing the prior network searching operation can be ensured, the network can be connected to the network with higher probability when the network is searched by using the prior network searching frequency point, and the success rate of network searching is improved.
And step 204, sequentially performing network searching operation based on the M preferential searching frequency points.
Specifically, the mobile terminal can sequentially perform network searching operations based on the M priority searching frequency points through the following substeps (1) to (2):
substep (1): and acquiring the signal quality of each preferentially searched network frequency point.
In this step, taking the signal quality as the signal intensity of the preferentially searched network frequency point as an example, correspondingly, the mobile terminal may detect the signal intensity of each preferentially searched network frequency point in real time based on each preferentially searched network frequency point, and for example, may perform a reception test based on each preferentially searched network frequency point, and take the intensity of the received signal as the signal intensity of the preferentially searched network frequency point. Of course, the signal quality may also be RSRQ, SNR, RSSI, and the like, which is not limited in the embodiment of the present invention.
Substep (2): and searching a cell corresponding to the network searching priority frequency point at each network searching priority frequency point in sequence according to the signal quality of each network searching priority frequency point from high to low.
Because the signal quality of the preferentially searched network frequency point is better, the probability that the mobile terminal is connected to the network based on the preferentially searched network frequency point is higher, therefore, in the step, the mobile terminal can search the cell corresponding to the preferentially searched network frequency point based on each preferentially searched network frequency point in sequence according to the sequence of the signal quality from high to low, and thus, the network searching operation is performed based on the sequence from high to low, so that the mobile terminal can search the connectable cell more quickly, and then is connected to the network more quickly. Wherein a cell represents a collection of base stations, each having a fixed frequency point/frequency band. Accordingly, after the network searching operation is carried out, connection is established with the first cell under the condition that the first cell is searched. Specifically, the first cell may be a cell searched based on the network searching priority, and the mobile terminal may send a registration request to the first cell under the condition that the first cell is searched based on the network searching priority, so as to establish a connection with the first cell, thereby implementing a network connection. If the registration request passes, the mobile terminal establishes connection with the first cell, and if the registration request does not pass, the mobile terminal can continue to search through other preferentially searched network frequency points and send the registration request.
For example, assuming that a sequence composed of N candidate search frequency points is (C1, C2, H1, H2, K1, and K2), the preferred search frequency points selected from the N candidate search frequency points are H1 and C1, and the mobile terminal establishes a connection with a cell corresponding to H1, then the mobile terminal may adjust H1 to the first position in the sequence composed of the N candidate search frequency points, and accordingly, the positions of the candidate search frequency points before H1 are sequentially shifted backward by one bit, the positions of the candidate search frequency points after H1 are kept unchanged, and at this time, the sequence composed of the N candidate search frequency points is (H1, C1, C2, H2, K1, and K2). In the implementation of the invention, if the mobile terminal establishes connection with the cell corresponding to the preferentially searched network frequency point, the preferentially searched network frequency point can be considered to have higher utilization value, and the success rate of the mobile terminal in the preferentially searched network frequency point for connecting the network is higher, so that the preferentially searched network frequency point can be adjusted to the first position in the sequence, and thus, the position of the to-be-selected searched network frequency point contained in the sequence is continuously updated based on the utilization value, so that in the subsequent step, the frequency point with lower utilization value can be eliminated based on the position of the to-be-selected searched network frequency point in the sequence.
Of course, the mobile terminal may also set a timer, when the mobile terminal establishes a connection with the cell corresponding to H1, the timer is used to count the connection duration with the cell, and when the connection duration between the mobile terminal and the cell reaches a preset duration threshold, the H1 is adjusted to the first position in the sequence formed by the N search frequency points to be selected, where the preset duration threshold may be set according to an actual situation, for example, the preset duration threshold may be half an hour, or 1 hour. Therefore, the stability of the prior searching frequency point corresponding to the connected cell can be avoided to be poor, and the prior searching frequency point with poor connection quality is prevented from being adjusted to the first position.
And step 206, under the condition that the connection is not established in the cell corresponding to each of the prior network searching frequency points, taking the frequency points except for each of the prior network searching frequency points as alternative frequency points, and sequentially performing network searching operation based on each of the alternative frequency points.
For example, assuming that all frequency points included in the network are a1, a2, B1, B2, C1, C2, H1, H2, K1, and K2, and no connection is established between the mobile terminal and the cell corresponding to H1 or the cell corresponding to C1, the mobile terminal may connect all frequency points except H1 and C1: a1, A2, B1, B2, C2, H2, K1 and K2 are used as alternative frequency points, and network searching operation is sequentially carried out on the basis of each alternative frequency point so as to ensure that the mobile terminal can be connected to the network.
For example, assuming that the mobile terminal establishes a connection with the cell corresponding to a2, the mobile terminal may adjust a2 to the first position in the sequence of the multiple candidate search frequency points in an insertion manner, and accordingly, because a2 is not included in the sequence of the multiple candidate search frequency points, positions of other candidate search frequency points in the sequence of the multiple candidate search frequency points are sequentially shifted backward, and at this time, the sequence of the multiple candidate search frequency points is (a2, C1, C2, H1, H2, K1, and K2). Certainly, the mobile terminal may also set a timer, when the mobile terminal establishes a connection with the cell corresponding to a2, the timer is used to count the connection duration with the cell, and when the connection duration between the mobile terminal and the cell reaches a preset duration threshold, the a2 is inserted into the first of the multiple candidate search frequency points. Therefore, the alternative searching frequency points with poor connection quality can be prevented from being added to the first position of the sequence.
And step 208, when the number of the search frequency points to be selected in the sequence is greater than the preset number threshold, sequentially deleting the search frequency points to be selected in the sequence from the search frequency point to be selected positioned at the last position in the sequence according to the sequence from the last position to the first position until the number of the search frequency points to be selected in the sequence is not greater than the preset number threshold.
In this step, the preset number threshold may be set according to an actual situation, for example, the preset number threshold may be 20, and when the number of the search frequency points to be selected is too large, the efficiency of performing a preferential network search based on the search frequency points to be selected may be lowered.
Further, when the number of the search frequency points to be selected in the sequence is greater than the preset number threshold, the mobile terminal deletes the search frequency points to be selected in the sequence from the last search frequency point to be selected. For example, if H1 is removed from the corresponding cell, H1 is eliminated as the sequence is continuously updated.
In summary, in another network searching method provided in the embodiments of the present invention, in a case that a network searching request is received, a mobile terminal calculates network searching adaptability of a to-be-selected searching frequency point, selects a preferential searching frequency point based on the network searching adaptability, and then sequentially performs network searching operations based on each preferential searching frequency point, where the to-be-selected searching frequency point is a frequency point with a signal quality greater than a preset quality threshold in a permanent location of the mobile terminal, and a frequency point with a better signal quality in a location where the mobile terminal resides is used as the to-be-selected searching frequency point, so as to avoid reducing network searching efficiency, and at the same time, selects a preferential searching frequency point from the to-be-selected searching frequency points based on the network searching adaptability to perform network searching, so as to ensure a higher probability of connecting to a network, improve success rate of network searching, and further, the mobile terminal may further adjust a preferential network searching frequency point corresponding to a connected cell, or adjust a candidate network searching frequency point corresponding to the connected cell to a first position in a sequence composed of N to-be-selected searching frequency points, the sequence is dynamically adjusted, the last searching frequency point to be selected is deleted, and the number of the searching frequency points to be selected in the sequence is not larger than a preset number threshold value, so that the number of the searching frequency points to be selected is not too large by deleting the searching frequency points to be selected through dynamic adjustment, the network searching efficiency is ensured, the searching frequency points to be selected in the sequence are also ensured to have higher utilization value, and the success rate of the mobile terminal for connecting the network based on the searching frequency points to be selected is ensured.
