Voice traffic of the current commercial 5G network is typically implemented through EPS FallBack (EPS FB). That is, the current 5G access network does not support Voice service, when a User Equipment (UE) initiates or receives a Voice call in the 5G access network, the UE needs to fall back to the 4G network in a redirection manner, the Voice service is provided by a Long Term Evolution-terminal (VoLTE) under the 4G network, and after the call ends, the UE returns to the 5G network.
At present, the voice service redirection mode generally determines the priority of a frequency point directly according to the successful times of fallback of the frequency point, and when the frequency point is higher, the priority is higher, and when the UE initiates or receives a voice call, the frequency point is preferably selected. The method for ordering the priority of the frequency points specifically comprises the following steps: after receiving the successful information of fallback, the UE sends the frequency point information of the current fallback cell to the base station; updating the successful times of the fallback of the frequency point of the current fallback cell; and determining the priority of the frequency point of the cell according to the updated successful times of fallback of the frequency point. When the subsequent UE initiates or receives the voice call, the voice call falls back to the frequency point with higher priority.
However, the existing redirection fallback method only performs priority sorting according to the successful times of fallback of the frequency points, so that the condition of fallback and blank stepping still exists, and the voice service establishment efficiency is affected.

Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.
Fig. 1 is a schematic architecture diagram of a communication system according to an embodiment of the present application. As shown in fig. 1, the communication system includes a terminal device 101, a 5G base station 102, and a 4G base station 103.
The terminal device 101 may be a mobile phone, a tablet computer, a smart bracelet, etc., and the terminal device 101 may be provided with various application software such as communication software, etc., and may perform a voice call. Terminal device 101 may interact with either 5G base station 102 or 4G base station 103, i.e., terminal device 101 may use a 5G network if 5G base station 102 is covered and may use a 4G network if 4G base station 103 is covered.
With the development of mobile communication networks, 5G networks are becoming popular, but the 5G base station 102 still does not form continuous coverage, so that the terminal device 101 can fall back to the 4G network in an area where the 5G base station 102 is not covered. The location of the user may change from time to time when the terminal device 101 is engaged in a voice call, and the terminal device 101 may need to be continuously switched between the 5G network and the 4G network. But frequent handovers between 5G networks and 4G networks tend to result in a poor user experience. In order to improve this situation, currently, an EPS FB method is generally adopted, and when a user uses the terminal device 101 to perform a voice service, the network of the terminal device 101 drops from 5G to 4G, and returns to the 5G network after the voice service is finished.
Each of the 5G base station 102 and the 4G base station 103 may cover and serve a plurality of cells, and each cell may be configured with a plurality of frequency points. For example, it may contain cells for 5G base station 102 1,1 Cell 1,2 Cell 1,3 Three cells, which refer to different defined logic concepts based on carrier frequencies, scrambling codes, etc. within the 5G base station 102 wireless coverage geographic area, each base station may comprise multiple cells; it may contain cells for the 4G base station 103 2,1 Cell 2,2 Cell 2,3 Three cells, which refer to different defined logical concepts based on carrier frequency, scrambling code, etc. within the 4G base station 103 wireless coverage geographical area. Each cell is configured with a plurality of operating frequency system sections with different frequency ranges, wherein the frequency of each fixed frequency section length can be divided into one frequency point. When the terminal device 101 uses the wireless network, it is generally required to be within a certain frequency range to communicate with other devices, that is, the terminal device 101 needs to step to a certain frequency point in the cell of the 5G base station 102 or the 4G base station 103 when performing the voice service.
Since the EPS FB mode is generally adopted when the terminal device 101 performs the voice service at present, the terminal device 101 falls back from the 5G network to the frequency point in the 4G network, which is a broad concern. In order to improve the call quality of the terminal device 101, the network redirection delay is smaller, and a blind redirection mode is generally adopted, that is, the network directly falls back to the frequency point with the highest priority. Currently, the priorities of the frequency points are generally ordered according to the number of successful falling times, that is, the higher the number of successful falling times of the frequency points is, the higher the priority of the frequency points is. When the terminal device 101 performs a voice call, it sends measurement data (MR data) to the 4G base station 103, where the measurement data includes information of a cell where the terminal device 101 falls back and information of a frequency point where the terminal device falls back, and updates the successful falling times of the frequency point according to the information of the frequency point, and sorts priorities of all frequency points in a cell associated with the falling cell and in the falling cell, so as to obtain a new priority sequence, so that when the subsequent terminal device 101 performs a voice call, the network falls back from 5G to 4G, and falls back to the frequency point with the highest priority preferentially. However, the frequency points are prioritized only by the number of successful fallbacks, so that there is still a case where the fallbacks are stepped on empty.
For example, although the historical successful fallback times of a certain frequency point are highest, the actual signal strength may be poor, so that when the terminal device 101 falls back to the frequency point, the communication quality is poor, and thus the terminal device needs to switch to the rest of frequency points, and the user experience is affected.
In order to improve the user experience, a priority ordering mode of the frequency points needs to be optimized. More factors need to be considered in the priority ranking, and various abnormal conditions such as frequency point switching and the like need to be considered.
It should be understood that the illustration in fig. 1 is only one architectural diagram of a communication system, and that the number of serving cells of the 4G base station and the number of serving cells of the 5G base station shown in fig. 1 are merely exemplary, and that a greater or lesser number is within the scope of the present application. In addition, the terminal device 101 shown in fig. 1 may be, but not limited to, a mobile phone, and the product form of the terminal device 101 is not particularly limited in this application.
The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a flowchart of a redirection fallback method according to an embodiment of the present application. The redirection fallback method may be applied to the communication system shown in fig. 1, and the method may be performed by the 5G base station 102 shown in fig. 1, or may be performed by a server, a computer, or other physical devices, where the specific product form and number of the execution subject are not specifically limited in this embodiment. The following description will take a 5G base station as an execution body as an example. As shown in fig. 2, the method includes:
s201, access state information of the terminal equipment is obtained, wherein the access state information comprises at least one of information for indicating whether the terminal equipment is successfully accessed to a first target frequency point, information for indicating whether the terminal equipment drops calls in the first target frequency point in a first time period or information for indicating whether the terminal equipment is switched from the first target frequency point to other frequency points in a second time period, and the first target frequency point is a fallback frequency point of the terminal equipment.
The terminal device may be the terminal device 101 in fig. 1, and specifically may be a mobile phone, an intelligent bracelet, or other devices. The access state information refers to information about a frequency point where the terminal device falls back in a voice call process and whether an abnormal event occurs or not, which is sent by the terminal device after the voice service is finished. The first target frequency point is a frequency point which is stepped on by priority when the middle terminal equipment initiates the voice call, namely a frequency point with highest priority in a cell serving the terminal equipment. The first period of time is a preset arbitrary length of time, such as 1 second, 3 seconds, etc. The second period of time is a preset arbitrary length of time, for example, 5 seconds, 1 minute, or the like. The other frequency points are frequency points except the first target frequency point in the frequency points configured in the cell of the 4G base station covering the terminal equipment.
The access state information includes, in addition to information about whether the first target frequency point is successfully accessed, whether an abnormal event such as call drop or frequency point switching occurs in a short period, that is, the access state information includes various information capable of reflecting the signal condition of the frequency point. For example, the access status information may be: the terminal equipment successfully steps on the first target frequency point and switches to the second target frequency point 20 seconds after the terminal equipment is accessed to the first target frequency point. The above access state information indicates that, although the terminal device successfully accesses the first target frequency point, the frequency point is switched in a short period.
S202, determining whether the first target frequency point is a reasonable target frequency point according to the access state information.
The reasonable target frequency point refers to a frequency point which is successfully accessed by the terminal equipment and can enable the terminal equipment to carry out polar voice service in a good network state. Whether the first target frequency point can be successfully accessed by the terminal equipment or not, and whether the terminal equipment can successfully finish the voice service or not are contained in the access state information.
S203, counting the times that the first target frequency point is not a reasonable target frequency point.
The fact that the target frequency point is not reasonable means that the terminal equipment is not successfully accessed to the frequency point or the abnormal events such as call drop or frequency point switching occur after the target equipment is accessed to the frequency point.
S204, determining whether the first target frequency point is continuously used as a fallback frequency point according to the times that the first target frequency point is not the reasonable target frequency point.
If the 5G base station determines that the first target frequency point is not a reasonable target frequency point according to the access state information, the first target frequency point is indicated to have a poor signal state in the voice call process, so that the terminal equipment cannot successfully fall back to the first target frequency point or even fall back to the first target frequency point, the terminal equipment cannot maintain the normal voice call. If the first target frequency point is marked for many times and is not a reasonable target frequency point, the signal state of the frequency point is poor in most cases, and good network service state is difficult to provide for the terminal equipment. Therefore, the 5G base station needs to reduce the priority of the first target frequency point, and does not take the frequency point as the target frequency point when the subsequent terminal equipment falls back.
It should be understood that the priorities of the multiple frequency points may be the same, or the priorities of the frequency points may be different. For example, assuming that the total number of the frequency points is 20, according to the priority ranking, the priority of the 20 frequency points can be divided into 5 grades, each grade can contain four frequency points, and when the terminal equipment falls back to the frequency point with the highest priority, any frequency point in the highest priority grade can be selected; the 20 frequency points can be divided into 20 grades, and each grade contains one frequency point, so that when the terminal equipment falls back, the frequency point with the highest priority is accessed.
According to the redirection fallback method provided by the application, when the priorities of the frequency points are ordered, whether the terminal equipment has abnormal events such as short-term call drop or frequency point switching or not during voice communication is considered according to the access state information fed back by the terminal equipment, and the signal conditions of all the frequency points can be judged more comprehensively by considering various abnormal events, so that the fallback and foot-and-hold times of the terminal equipment are reduced, the voice service establishment efficiency is improved, and the user experience is improved.
Fig. 3 is a second flowchart of a redirection fallback method according to an embodiment of the present application. The redirection fallback method may be applied to the communication system shown in fig. 1, and the method may be performed by the 5G base station 102 shown in fig. 1, or may be performed by a server, a computer, or other physical devices, where the specific product form and number of the execution subject are not specifically limited in this embodiment. The following description will take a 5G base station as an execution body as an example. As shown in fig. 3, the method includes:
s301, acquiring access state information of the terminal equipment, wherein the access state information comprises at least one of information for indicating whether the terminal equipment is successfully accessed to a first target frequency point, information for indicating whether the terminal equipment drops a call in the first target frequency point in a first time period or information for indicating whether the terminal equipment is switched from the first target frequency point to other frequency points in a second time period, and the first target frequency point is a fallback frequency point of the terminal equipment.
It should be understood that the specific embodiment of S301 is similar to S201 in fig. 2, and will not be described here again.
S302, determining whether the terminal equipment is successfully accessed to a first target frequency point;
if yes, then execute S303;
if not, the first target frequency point is not a reasonable target frequency point, and S305 is executed.
Whether the terminal equipment is successfully accessed to the first target frequency point or not, namely the terminal equipment searches a cell on the first target frequency point and successfully resides.
S303, determining whether the terminal equipment successfully establishes voice service on a first target frequency point;
if yes, executing S304;
if not, the first target frequency point is not a reasonable target frequency point, and S305 is executed.
It should be understood that, although the terminal device successfully accesses the first target frequency point, the terminal device needs to establish the voice service at the frequency point successfully, and the network signal strength of the frequency point is required to be stronger.
S304, determining whether the terminal equipment drops calls in a first time period or is switched from a first target frequency point to other frequency points in a second time period;
if yes, the first target frequency point is not a reasonable target frequency point, and S305 is executed.
If not, the first target frequency point is a reasonable target frequency point.
The first time period and the second time period are both of preset time lengths. The call drop means that the terminal equipment is abnormally interrupted in the voice call process and cannot continue normal call.
The 5G base station determines that the first target frequency point is a reasonable target frequency point and needs to sequentially pass through the judging conditions in S302, S303 and S304, firstly the terminal equipment successfully accesses the first target frequency point, then the voice service is successfully established on the first target frequency point, no call drop occurs in a first time period, or no frequency point switching occurs in a second time period. And after the conditions are sequentially met, the first target frequency point is a reasonable target frequency point. If the first target frequency point is not satisfied with any of the conditions, the first target frequency point is not a reasonable target frequency point.
Exemplary, in FIG. 1, 5G cells 1，1 The function of voice blind redirection to 4G network is enabled, and then the user in the cell uses the terminal equipmentAnd when the voice service is initiated, blind redirection is carried out to the frequency point with the highest priority in the 4G cell. If the frequency point with the highest priority is the frequency point 2, the frequency point 2 is equivalent to the first target frequency point, and the terminal equipment used by the user searches the cell on the frequency point 2 and resides successfully, namely, the condition that the terminal equipment is successfully accessed to the first target frequency point is satisfied; the terminal equipment of the user also successfully establishes the voice service on the frequency point 2, namely, the condition of successfully establishing the voice service on the first target frequency point is met; if the terminal device of the user successfully establishes the voice service at the frequency point 2, then it is detected that the signal condition of the frequency point 3 is better, then the user switches to the frequency point 3, the time that the terminal device maintains the voice service at the frequency point 2 is 3 seconds, if the preset second time period is 5 seconds, then the condition that the frequency point switching does not occur in the second time period is not satisfied, and the frequency point 2 is not a reasonable target frequency point. If the time for the terminal equipment to keep the voice service on the frequency point 2 is 6 seconds, the condition that the frequency point switching does not occur in the second time period is met; meanwhile, if the terminal equipment does not drop calls within 10 seconds and the first time period is 8 seconds, the condition that the call drop does not occur within the first time period is met is indicated, and at this time, the frequency point 2 is a reasonable target frequency point.
Before determining the priority of the first target frequency point, the 5G base station firstly determines whether the terminal equipment is successfully accessed to the first target frequency point; whether the voice service is successfully established at the first target frequency point or not; whether a call drop occurs within a first time period; whether frequency point switching occurs in the second time period or not, whether the first target frequency point is a reasonable target frequency point or not is further determined, the signal condition of the first target frequency point is detected from more angles, whether the first target frequency point is suitable to be used as the target frequency point or not is determined, the phenomenon that the terminal equipment falls back and steps on the air is reduced, and the efficiency of successfully establishing voice service by the terminal equipment is improved.
S305, counting the times that the first target frequency point is not a reasonable target frequency point.
When the first target frequency point does not meet any of the conditions, the corresponding description is that the first target frequency point is not a reasonable target frequency point, and the times that the first target frequency point is not the reasonable target frequency point are updated.
S306, determining whether the number of times that the first target frequency point is not a reasonable target frequency point is larger than or equal to a first threshold value; and/or whether the proportion of the first target frequency point which is not a reasonable target frequency point is larger than or equal to a second threshold value, wherein the proportion of the first target frequency point which is not a reasonable target frequency point is the ratio of the times of the first target frequency point which is not a reasonable target frequency point to the times of fallback of the terminal equipment.
If yes, the first target frequency point does not continue to serve as a fallback frequency point, and S307 is executed;
if not, the first target frequency point continues to be used as the fallback frequency point.
The first preset threshold is a preset arbitrary value greater than or equal to 0, for example, 10, 40, etc.; the second threshold is an arbitrary value of 0 or more and 1 or less, for example, 30%, 50%, or the like. The number of times of falling back of the terminal device refers to the total number of times that the terminal device falls back to the first target frequency point, and the terminal device is not necessarily the terminal device for establishing the voice service at this time, and can be any terminal device.
The 5G base station determines whether the first target frequency point continues to serve as a fallback frequency point or not, and two judging conditions exist. Under the condition, if the number of times that the first target frequency point is not a reasonable target frequency point is greater than or equal to a first threshold value, determining that the first target frequency point does not continue to serve as a fallback frequency point. In another case, if the proportion of the first target frequency point which is not the reasonable target frequency point is greater than or equal to the second threshold value, it is determined that the first target frequency point does not continue to serve as the fallback frequency point. In still another case, the number of times that the first target frequency point is not a reasonable target frequency point is greater than or equal to a first threshold value, and meanwhile, the proportion that the first target frequency point is not a reasonable target frequency point is greater than or equal to a second threshold value, and at the moment, it is determined that the first target frequency point does not continue to serve as a fallback frequency point.
For example, in a certain period of time, for example, in one month, the number of times that the frequency point 2 is recorded as the frequency point which is not a reasonable target frequency point is 500 times, and the preset first threshold value is 100 times, the number of times that the frequency point 2 is recorded as the frequency point which is not a reasonable target frequency point is greater than or equal to the first threshold value; meanwhile, the frequency point 2 is marked that the proportion of the frequency point which is not a reasonable target frequency point is 80%, and the preset second threshold value is 50%, and the proportion of the frequency point 2 which is not a reasonable target frequency point is greater than or equal to the second threshold value, at the moment, the frequency point 2 is not continuously used as a fallback frequency point, namely the priority of the frequency point 2 is reduced. The judging condition is that whether the number of times that the first target frequency point is not a reasonable target frequency point is larger than or equal to a first threshold value is determined; and, if the first target frequency point is not the case if the proportion of the reasonable target frequency point is greater than or equal to the second threshold. If the judgment condition is that the number of times that the first target frequency point is not a reasonable target frequency point is greater than or equal to a first threshold value; or if the proportion of the first target frequency point which is not the reasonable target frequency point is larger than or equal to the second threshold value, the frequency point 2 is marked as the frequency of the frequency point which is not the reasonable target frequency point is larger than or equal to the first threshold value, and the frequency point 2 is marked as the frequency point which is not the reasonable target frequency point is larger than or equal to the second threshold value, as long as one of the frequency points is satisfied, the frequency point 2 does not continue to serve as the fallback frequency point.
By counting whether the first target frequency point is a reasonable target frequency point for many times and judging whether the first target frequency point is continuously used as a fallback frequency point through a threshold value, the priority of the first target frequency point is more reasonably and comprehensively determined, and the signal condition of the first target frequency point is more accurately determined conveniently.
S307, determining a second target frequency point according to the access state information, and taking the second target frequency point as a subsequent fallback frequency point.
The second target frequency point is the frequency point with the highest priority, and since the first target frequency point is the frequency point with the highest priority before, the priority of the first target frequency point is reduced and the first target frequency point is not continuously used as the fallback frequency point, so that the new frequency point with the highest priority, namely the second target frequency point, needs to be determined, the subsequent terminal equipment can be directly accessed, the timeliness of the blind redirection fallback mode is reduced, and the efficiency of the terminal equipment for establishing the voice service is improved.
In a possible implementation manner, determining the second target frequency point includes:
if the terminal equipment is not accessed to the first target frequency point but is accessed to other frequency points, the other frequency points are determined to be candidate frequency points.
If the terminal equipment is switched from the first target frequency point to other frequency points in the second time period, the other frequency points are determined to be the candidate frequency points.
And counting the times of other frequency points determined as candidate frequency points.
The candidate frequency points refer to frequency points used for subsequently determining the second target frequency point.
The terminal equipment is not connected with the first target frequency point but is connected with other frequency points, or the terminal equipment is switched from the first target frequency point to other frequency points in a second time period, so that the network signal condition of the other frequency points is better than that of the first target frequency point, and the condition of the network signal of the first target frequency point is better because the first target frequency point is the frequency point with the highest priority, if one of the two conditions occurs, the condition of the signal of the other frequency point is good, the signal of the other frequency point can be used as a candidate frequency point, the second target frequency point can be determined later, the phenomenon that the terminal equipment steps down and steps down is reduced, and the voice service establishment efficiency is further improved.
Determining whether the number of times that other frequency points are determined to be candidate frequency points is greater than or equal to a third threshold; and/or the number of the groups of groups,
the other frequency points are determined to be whether the proportion of the candidate frequency points is larger than or equal to a fourth threshold value, wherein the proportion of the other frequency points is determined to be the proportion of the number of times the other frequency points are determined to be the candidate frequency points to the number of times the terminal equipment falls back to the other frequency points;
if yes, determining other frequency points as second target frequency points;
If not, the other frequency points are not the second target frequency points.
The third preset threshold is a preset arbitrary value greater than or equal to 0, for example, 20, 30, etc.; the fourth threshold is an arbitrary value of 0 or more and 1 or less, for example, 40%, 50%, or the like.
The following three embodiments can be used by the 5G base station to determine whether other frequency points are second target frequency points. In one possible implementation, it is determined whether the number of times that the other frequency point is determined as the candidate frequency point is greater than or equal to a third threshold. For example, if the number of times that the frequency point 4 is determined as the candidate frequency point is 100 times and the third threshold value is 80 times within a certain period of time, for example, one month, the number of times that the frequency point 4 is determined as the candidate frequency point is greater than the third threshold value, and the frequency point 4 is determined as the second target frequency point. In another possible implementation, it is determined whether the proportion of other frequency points determined as candidate frequency points is greater than or equal to a fourth threshold. For example, if the frequency point 4 is determined to be 80% of the candidate frequency points and the fourth threshold is 60% within a certain period of time, for example, within one month, the frequency point 4 is determined to be greater than the fourth threshold and the frequency point 4 is determined to be the second target frequency point. In yet another possible embodiment, it is determined whether the number of times the other frequency point is determined as the candidate frequency point is greater than or equal to the third threshold value, and it is determined whether the proportion of the other frequency point determined as the candidate frequency point is greater than or equal to the fourth threshold value. For example, if the number of times that the frequency point 4 is determined as the candidate frequency point is 80 times and the third threshold is 60 times within a certain period of time, for example, one month, while the frequency point 4 is dropped by the terminal device 100 times, the frequency point 4 is determined as the ratio of the candidate frequency points is 80% and the fourth threshold is 60%, the ratio of the frequency point 4 is determined as the candidate frequency point is greater than the fourth threshold, and at this time, the frequency point 4 is determined as the second target frequency point.
It should be understood that in the three possible embodiments, the number of candidate frequency points is one. And determining the network signal condition of the candidate frequency point by judging the threshold value of the frequency and/or the proportion of the candidate frequency point, so that the network signal condition of the determined second target frequency point is excellent, and the condition that the terminal equipment falls back and steps on the sky is reduced conveniently.
And if the second target frequency point comprises a plurality of frequency points, the plurality of frequency points are prioritized according to the proportion or the times that other frequency points are determined to be candidate frequency points.
The plurality of frequency points refer to a plurality of second target frequency points, and the frequency point with the highest priority is determined as the subsequent falling frequency point through priority sorting. The higher the number or proportion of times the second target frequency point is determined as a candidate frequency point, the higher its priority. For example, the number of times the second target frequency point 1 is determined as the candidate frequency point is 120 times, the number of times the second target frequency point 2 is determined as the candidate frequency point is 100 times, and the priority of the second target frequency point 1 is higher. By the technical scheme, the efficiency of establishing the voice service by the terminal equipment is improved.
Fig. 4 is a schematic process diagram of a redirection fallback method according to an embodiment of the present application. As shown in fig. 4, the redirect fallback method includes 6 processes in total.
In the process 1, the terminal device sends access status information to the 5G base station. In the process 2, whether the first target frequency point is a reasonable target frequency point is determined through analysis of the access state information, and a specific method for determining whether the first target frequency point is a reasonable target frequency point is similar to the specific implementation process of S302 to S304 in fig. 3. Counting the number of times that the first target frequency point is determined to be not a reasonable target frequency point, and assuming that the number of times is 100 times and the preset first threshold value is 80 times, at this time, in the process 3, determining that the first target frequency point does not continue to serve as a fallback frequency point.
Since the priority of the first target frequency point is lowered, the 5G base station needs to determine a new fallback frequency point again. In the process 4, the candidate frequency points of the fallback of the terminal equipment are recorded. The candidate frequency points are frequency points which are directly accessed by the terminal equipment and are not successfully accessed to the first target frequency point; or the terminal equipment successfully accesses the first target frequency point, but the target frequency point is switched when the frequency point is switched in the second time period. And 5, determining the candidate frequency point as a second target frequency point according to the times and/or the proportion of the frequency points determined as the candidate frequency point by other frequency points. For example, the number of times that the other frequency point is determined as the candidate frequency point is 120 times, and the preset third threshold value is 100 times, and at this time, the candidate frequency point is determined as the second target frequency point. In the process 6, if the number of the second target frequency points is multiple, selecting the frequency point with the highest priority from all the second target frequency points as the subsequent fallback frequency point. For example, the number of the second target frequency points is 3, which are respectively the second target frequency point 1, the second target frequency point 2 and the second target frequency point 3, and the times of determining the second target frequency point 1, the second target frequency point 2 and the second target frequency point 3 as the candidate frequency points are 140 times, 120 times and 150 times in sequence, so that the second target frequency point 3 is determined to be the subsequent falling frequency point. The terminal device will then establish the voice service directly back to the second target frequency point 3.
