The present disclosure is mainly applied to a scenario in which a terminal switches mobile communication networks, in recent years, mobile operators are working to clear the GSM network, but if GSM is completely turned off, users cannot use the network in a part of the coverage area where GSM signals are strong, for example, on a train or in a rural environment, the mobile communication networks with high transmission rate (such as 4G and 5G mobile networks) tend to have poor signals, in contrast to the coverage area of 2G signals (such as GSM signals) which is wider, if GSM is completely turned off for the area corresponding to the train or the rural environment, users in these areas cannot perform high quality mobile communication.
In the related art, a cloud control mode is generally adopted to control the switching of a certain regional GSM network service, for example, when users in a certain region complain, the regional GSM network service is turned on through the cloud control, but the scheme has the defects of hysteresis, a period of time is required to be studied after the user complains, the cloud control is prepared, the problem cannot be solved for the user in a short time, the user experience is seriously affected, in addition, the cloud control is controlled through the region, and when the user leaves the region, the switching of the GSM network service cannot be timely controlled according to the requirement of the user.
In order to solve the above-mentioned problems, the present disclosure provides a method, an apparatus, and a storage medium for switching a communication network, where in a case where a specified communication network (such as a GSM network, a W-CDMA network, etc.) of a terminal is closed, a first signal strength parameter of a target signal in a current camping cell and a second signal strength parameter of a preset communication signal received by the terminal may be acquired by the terminal, where the preset communication signal is a communication signal corresponding to the specified communication network, and the target signal includes at least one communication signal other than the preset communication signal, and then, according to the first signal strength parameter and the second signal strength parameter, it is determined whether the terminal satisfies a preset opening condition, and in a case where it is determined that the terminal satisfies the preset opening condition, the specified communication network is opened; and switching the current communication network of the terminal to the appointed communication network, so that the terminal can autonomously judge the signal intensity of each communication signal in the communication network environment where the terminal is currently positioned according to the first signal intensity parameter of the target signal and the second signal intensity parameter of the preset communication signal under the condition that the appointed communication network is closed, and timely open the appointed communication network under the condition that the terminal is determined to meet the preset opening condition, so that a user can keep network experience, the user does not need to wait for user complaints, the limitation of the area of the network is avoided, the network returning of the appointed communication network through the terminal is realized, the development requirement of operators is met, and the user experience is also met.
The following detailed description of specific embodiments of the present disclosure refers to the accompanying drawings.
Fig. 1 is a flowchart illustrating a method of switching a communication network, which can be applied to a terminal (e.g., a mobile phone) having a mobile communication function, according to an exemplary embodiment, as shown in fig. 1, the method comprising the steps of:
in step S101, under the condition that the specified communication network of the terminal is closed, a first signal strength parameter of a target signal in a cell where the terminal currently resides and a second signal strength parameter of a preset communication signal corresponding to the specified communication network are obtained, where the target signal includes at least one communication signal other than the preset communication signal.
Wherein the specified communication network may comprise a GSM network and/or a W-CDMA (Wide band Code Division Multiple Access ) network, the preset communication signal is a communication signal corresponding to the specified communication network, i.e. the preset communication signal is a communication signal transmitted by the specified communication network. For example, if the specified communication network is a GSM network, the preset communication signal is a GSM signal corresponding to the GSM network; if the designated communication network is a W-CDMA network, the preset communication signal is a W-CDMA signal corresponding to the W-CDMA network; if the specified communication network includes a GSM network and a W-CDMA network, the preset communication signal includes a GSM signal corresponding to the GSM network and a W-CDMA signal corresponding to the W-CDMA network.
In order to promote the development of mobile communication networks towards higher transmission rates, mobile operators need to gradually clear a specified communication network such as a GSM network, a W-CDMA network, etc., so that the specified communication network of a terminal is normally in a closed state, but if the specified communication network is completely closed, in a situation that a part of the specified communication network has a strong coverage area and no good 3G/4G/5G signal exists in the area, the user cannot use the communication network, so that the use experience of the user is affected, and therefore, the hardware of the terminal default supports the specified communication network, and in this step, the specified communication network is only closed by default at the software level of the terminal.
Assuming that the designated communication network is a GSM network, the predetermined communication signal is a GSM signal, and the target signal includes at least one other communication signal other than the GSM signal, for example, a 3G signal, a 4G signal, a 5G signal, etc., it should be noted that the predetermined communication signal is typically a GSM signal of a neighboring cell of the current camping cell.
The signal strength parameter may include a number of signal bins or a power parameter of a received signal (such as RSSI (Received Signal Strength Indicator, strength indication of a received signal), RSCP (Received Signal Code Power ), RSRP (Reference Signal Receiving Power, reference signal received power), where the number of signal bins is used to represent a signal strength of a certain communication signal received by a terminal, and generally, the higher the number of signal bins is, the stronger the signal strength of a corresponding communication signal is represented, where the number of signal bins may be calculated by the terminal according to the received power parameter (or referred to as a signal energy value) of the certain communication signal.
In step S102, the specified communication network is started when the terminal is determined to satisfy a preset starting condition according to the first signal strength parameter and the second signal strength parameter.
The preset starting condition is a condition that a signal quality condition of a current resident cell corresponding to the characterization terminal does not meet a current communication requirement of a user, and a signal quality condition of a preset communication signal of a neighboring cell of the current resident cell can meet the current communication requirement of the user.
The preset opening condition may include any one of the following three conditions:
condition one: the first signal strength parameter is less than or equal to a first preset threshold and the second signal strength parameter is greater than or equal to a second preset threshold.
The first preset threshold is an upper limit value of signal strength representing poor signal quality of the target signal, and if the first signal strength parameter is smaller than or equal to the first preset threshold, it can be determined that the signal quality of the target signal in the current residence cell corresponding to the terminal is poor, and normal communication service cannot be provided for the user; the second preset threshold is a lower signal strength limit value representing that the signal quality of the preset communication signal is better, and if the second signal strength parameter is greater than or equal to the second preset threshold, it can be stated that the signal quality of the preset communication signal received by the current terminal is better.
Taking the example that the first signal strength parameter includes a first number of signal frames corresponding to the target signal, and the second signal strength parameter includes a second number of signal frames corresponding to the preset communication signal, in one possible implementation manner, the preset starting condition may include:
the first number of signal bins is less than or equal to a first preset number of signal bins, and the second number of signal bins is greater than or equal to a second preset number of signal bins.
For example, assuming that the preset communication signal is a GSM signal, the target signal is a 3G signal, a 4G signal, and a 5G signal, if the first number of signal cells is less than or equal to the first preset number of signal cells (e.g. 2 cells), it may be determined that the signal quality of the 3G signal, the 4G signal, and the 5G signal in the current residence cell corresponding to the terminal is poor, normal communication service cannot be provided for the user, and the second number of signal cells is greater than or equal to the second preset number of signal cells (e.g. 4 cells), which may indicate that the quality of the GSM signal received by the current terminal is better.
In addition, under the condition that the target signal quality of the current residence cell of the terminal is poor and the terminal can receive the preset communication signal with good signal quality, if the service cell corresponding to the preset communication signal is recorded in the preset database, the specified communication network of the terminal can be directly started, so that the subsequent detection steps can be reduced, and the switching efficiency of the network can be improved, therefore, under the condition that the terminal is determined to meet the first condition, whether the specified communication network is started can be determined by the following steps:
determining whether a cell corresponding to the preset communication signal is stored in a preset database, wherein the cell corresponding to the preset communication signal comprises a neighboring cell of the current resident cell; if the first signal strength parameter is less than or equal to a first preset threshold and the second signal strength parameter is greater than or equal to a second preset threshold (i.e., if the condition one is satisfied), the designated communication network may be started if the preset database stores the cell corresponding to the preset communication signal.
Condition II: the first signal strength parameter is less than or equal to the first preset threshold during a preset time period, and the second signal strength parameter is greater than or equal to the second preset threshold during the preset time period.
In order to improve accuracy of determining signal quality of a target signal of a current camping cell and a preset communication signal corresponding to a neighboring cell, a time limit may be added on the basis of determining a size relationship between a corresponding number of signal cells and a corresponding preset number of signal cells, and the first signal strength parameter includes a first number of signal cells corresponding to the target signal, and the second signal strength parameter includes a second number of signal cells corresponding to the preset communication signal as an example, in another possible implementation of the present disclosure, the preset starting condition may include:
the first signal cell number is less than or equal to the first preset signal cell number in a preset time period, and the second signal cell number is greater than or equal to the second preset signal cell number in the preset time period.
And (3) a third condition: under the condition that the signal quality of the communication signal received by the terminal is periodically detected, detection results of continuous preset times meet preset starting sub-conditions, the preset starting sub-conditions comprise that the first signal intensity parameters are smaller than or equal to the first preset threshold value in a preset time period, and the second signal intensity parameters are larger than or equal to the second preset threshold value in the preset time period, and the preset time period is the duration of single detection.
In order to further improve accuracy of signal quality judgment of a target signal of a current resident cell and a preset communication signal corresponding to a neighboring cell, signal quality of a signal received by a terminal may be continuously detected for multiple times on the basis of adding time limitation, so in another possible implementation manner, the preset starting condition may include:
under the condition that the signal quality of the communication signal received by the terminal is periodically detected, detection results of continuous preset times meet preset starting sub-conditions, the preset starting sub-conditions comprise that the first signal grid number is smaller than or equal to the first preset signal grid number in a preset time period, the second signal grid number is larger than or equal to the second preset signal grid number in the preset time period, and the preset time period is the duration of single detection.
For example, continuing taking the preset communication signal as a GSM signal, where the target signal is a 3G signal, a 4G signal, and a 5G signal, the signal quality of the 3G signal, the 4G signal, the 5G signal, and the signal quality of the GSM signal of the neighboring cell in the current camping cell may be detected once every 3 seconds, and the duration of each detection is 5 seconds (i.e., the preset time period), so, if the detection results of 3 consecutive times (i.e., the continuous preset times) are all the following results: in the lasting 5 seconds, the number of the first signal cells of the 3G signal, the 4G signal and the 5G signal in the current residence cell is smaller than or equal to 2 cells, and the number of the second signal cells of the adjacent cell GSM signal received by the terminal in the lasting 5 seconds is larger than or equal to 4 cells, which means that the 3G/4G/5G signal of the current residence cell is poor, and the signal quality of the adjacent cell GSM signal is good.
In the above-described case where the specified communication network includes one communication network, how to determine whether to turn on the specified communication network is described above, the specified communication network may also include two communication networks of a GSM network and a W-CDMA network, and in this case, as shown in fig. 2, whether to turn on the specified communication network may be determined by:
in step S201, the W-CDMA network is turned on if the terminal is determined to satisfy the preset turn-on condition according to the first signal strength parameter and the second signal strength parameter of the W-CDMA signal.
Considering that the W-CDMA signal has a higher network system and a faster signal transmission rate than the GSM signal, if the terminal captures both the GSM signal and the W-CDMA signal, the signal quality of the W-CDMA signal may be preferentially detected, so after executing step S201, if it is determined that the terminal satisfies the preset starting condition, the W-CDMA network may be started, so that the terminal may perform communication based on the W-CDMA signal.
It should be noted that, the specific implementation manner of determining whether the terminal meets the preset starting condition according to the first signal strength parameter and the second signal strength parameter of the W-CDMA signal and determining whether the terminal meets the preset starting condition according to the first signal strength parameter and the second signal strength parameter of the GSM signal in step S202 is the same as the implementation manner in step S102 in embodiment 1 shown in fig. 1, and is not repeated here.
In step S202, if it is determined that the terminal does not meet the preset on condition according to the first signal strength parameter and the second signal strength parameter of the W-CDMA signal, it is determined whether the terminal meets the preset on condition according to the first signal strength parameter and the second signal strength parameter of the GSM signal.
As described above, in the case where the signal quality of the W-CDMA signal is preferentially detected and it is determined that the terminal does not meet the preset on condition according to the first signal strength parameter and the second signal strength parameter of the W-CDMA signal, the signal quality of the GSM signal may be continuously detected, that is, whether the terminal meets the preset on condition is determined according to the first signal strength parameter and the second signal strength parameter of the GSM signal.
In step S203, the GSM network is turned on if the terminal meets the preset turn-on condition according to the first signal strength parameter and the second signal strength parameter of the GSM signal.
By executing this step, if it is determined that the terminal meets the preset starting condition, the GSM network may be started, so that the terminal may communicate based on GSM signals.
In step S103, the current communication network of the terminal is switched to the specified communication network, which is downward compatible with the specified communication network.
The network system of the current communication network is generally higher than the specified communication network, and the fact that the current communication network is downward compatible with the specified communication network means that when a terminal supporting the current communication network performs service communication based on the current communication network, if the current communication network is poor in signal quality, the current communication network can be switched to the specified communication network with a lower network system for performing service communication, in other words, when the terminal can use the communication signal of the current communication network for performing communication service, the terminal can also use the communication signal corresponding to the specified communication network for performing communication service.
For example, assuming that the specified communication network is a GSM network, the current communication network may include any one of 3G, 4G, and 5G networks, and taking a 5G signal as an example, the 5G signal has a higher network format than a GSM signal, and the 5G signal has characteristics of high transmission rate, low delay, and the like.
After the terminal switches the current communication network to the appointed communication network, cell switching can be performed, namely, the current resident cell of the terminal is switched to a neighboring cell corresponding to the preset communication signal, so that high-quality communication service based on the preset communication signal is realized.
By adopting the method, the terminal can autonomously judge the signal intensity of each communication signal in the communication network environment where the terminal is currently located according to the first signal intensity parameter of the target signal and the second signal intensity parameter of the preset communication signal under the condition that the specified communication network is closed, and timely open the specified communication network under the condition that the terminal is determined to meet the preset opening condition, so that a user can keep network experience, wait for user complaints and be not limited by the area of the network, and realize the network returning of the specified communication network through the terminal in a self-adaption mode, thereby meeting the development requirements of operators and meeting the user experience.
Fig. 3 is a flow chart illustrating a method of switching a communication network according to the embodiment shown in fig. 1, the method further comprising the steps of:
in step 104, a serving cell corresponding to the preset communication signal is obtained, and a cell identifier of the serving cell is recorded in a preset database.
By executing the step, the service cell corresponding to the preset communication signal with better signal quality can be recorded in the preset database in time, so that the next time the target signal quality of the current resident cell of the terminal is judged to be poor, if the terminal can receive the preset communication signal, and the service cell corresponding to the preset communication signal is recorded in the preset database, the appointed communication network of the terminal can be directly started, the subsequent detection steps are reduced, and the network switching efficiency is improved.
In one implementation manner of this step, the received preset communication signal may be parsed to obtain identification information characterizing the serving cell.
To meet the communication network maintenance requirements of different operators, the cell records in the preset database may be emptied periodically, for example every 7 days.
After the terminal switches the current communication network to the specified communication network, the current resident cell of the terminal is also switched to the service cell corresponding to the preset communication signal, for example, the GSM cell corresponding to the GSM signal with better signal quality, and then if it is detected that the current resident cell of the terminal is changed again, the current resident cell may be switched or reselected to the service cell corresponding to the 3G/4G/5G signal with better signal quality, because the terminal receives the 3G/4G/5G signal with better signal quality, the usage priority of the 3G/4G/5G signal is generally higher than that of the GSM signal, and therefore, after the current resident cell of the terminal is switched to the service cell corresponding to the preset communication signal, if it is determined that the current resident cell of the terminal is changed again (cell reselection or switching), the specified communication network may be closed, as shown in fig. 3, the method further includes the following steps:
In step S105, it is determined whether the current camping cell of the terminal has changed; in the event that a change of the currently camped cell is determined, the designated communication network is shut down.
