In one embodiment, as shown in FIG. 1, a method for operator network switching is provided, which may include:

Step 202, detecting whether the target network is in a signal gap; the target network is an operator network that is currently configured to be in use among multiple operator networks supported by the subscriber identity card;

Step 204, when the result of the detection is that the target network is in a signal gap, then at the end of the first period of time, it is detected whether the target network is in a signal gap, and when the number of consecutive detections that the target network is in a signal gap reaches a threshold, Switching to the next target network, and detecting whether the next target network is at a near signal point at the end of the second period of time.

Among them, the network is in a poor signal state, which means that the network is in a weak signal or no service state, and its data service performance and communication delay are extremely poor; the first period and the second period can be adjusted according to the actual situation, for example, the first period can be shorter than the second period ;By adjusting the first time period and the second time period, the interval time for detecting whether the target network is in a signal gap can be changed; the threshold value can also be adjusted according to the actual situation, and the interval time for switching to the next target network can be changed by adjusting the threshold value.

Specifically, the communication module detects whether the target network, that is, the operator network that is currently configured to be in use among the multiple operator networks supported by the subscriber identity card, is in a poor signal state, thereby judging whether the currently used operator network is in the Weak signal or no service state; when the detection result shows that the target network is in a poor signal state, it means that the currently used operator network (that is, the operator network currently configured for use) is in a weak signal or no service state, then the communication module At the end of the first period of time, check whether the target network is in a poor signal state again, and reconfirm whether the currently used operator network is in a signal or no service state, and the number of times the communication module continuously detects that the target network is in a signal low point When the threshold is reached, in order to prevent being in a weak signal or no service state for a long time, switch to the next target network, and detect whether the next target network is almost in signal at the end of the second period. Therefore, by setting the first time period and the second time period, the application performs automatic cyclic detection on the target network currently in use. If the number of times the communication module continuously detects that the target network is in a weak signal reaches the threshold, it means that the target network may be in a weak signal for a long time. or no service state, so as to switch to the next target network, and at the end of the second period, the next target network is also detected whether it is in a poor signal, and then a specific loop detection mechanism is formed, and the communication module automatically finds the network with good quality Operator network, to avoid the operator network that is currently configured to be in a weak signal or no service state for a long time.

This application can be implemented as an end user with a subscriber identification card supporting multiple operator networks, the end user includes a communication module, and the communication module uses a specific loop detection mechanism to detect the signal quality of the currently used operator network, and When it is detected that the operator network currently configured as in use is in a weak signal or no service state, that is, the target network is in a poor signal situation, at the end of the first period, check whether the target network is in a poor signal condition again and confirm Whether the target network is still in poor signal status, and the communication module switches to the next target network when the number of times the communication module continuously detects that the target network is in poor signal status reaches the threshold. Switch to the next operator's network when the signal is weak or no service for a long time, and the signal quality of the next operator's network is automatically cyclically detected, so as to automatically find a high-quality network. When the end user is in a certain operator's network signal is weak When there is no area covered by the operator's network, the operator's network switch is performed in a timely manner, allowing users to access a better network, improving network switching efficiency, preventing terminals from being in a weak signal or no service state for a long time, and ensuring user data services High performance rate and delay, effectively improving user experience.

In one of the embodiments, as shown in Figure 2, the operator network switching method may also include:

Step 302 , when the result of the detection is that the target network is not in a signal barrier, it is detected whether the target network is in a signal barrier at the end of the third period of time.

In a specific example, the first period is less than the second period; the first period is less than the third period.

Specifically, when the detection result shows that the target network is not in a poor signal state, it means that the signal quality of the target network is good, and it is not in a weak signal or no service state, and the communication module will check the target network again at the end of the third period. It is in the detection of poor signal, so that when it is detected that the signal quality of the operator network that is currently configured to be in use is good, the signal quality of the operator network is continuously and automatically cyclically detected to ensure that the currently used operator network is a high-quality network. Until it detects that the target network is in a signal gap, the communication module will detect whether the target network is in a signal gap at the end of the first period, and switch to the next a target network. The first time period is less than the second time period, and the first time period can also be less than the third time period. For example, the first time period can be 5 seconds, and the second time period and the third time period can be 30 seconds. Therefore, when the communication module detects that the target network is not in In the case of weak signal, signal detection can be performed on the operator’s network after a long time interval to save energy consumption. When the communication module detects that the target network is in poor signal, it can detect the signal in a short time interval Then detect the target network to prevent the weak signal or no service state for a long time, switch the operator network in time, and perform signal quality detection on the next target network to be switched at a longer time interval.

For example, when an end user that includes a communication module and has a subscriber identification card that supports multiple operator networks uses a certain operator network, and the network quality of the operator is good, the operator will automatically send the user identification card at a longer time interval (for example, 30 seconds). The signal quality of the operator's network is continuously tested. When the terminal user moves to another area where the operator's network quality is very weak, it will automatically use a lower A short time interval (for example, 5 seconds) detects whether the operator's network is in a poor signal situation again, and if the number of consecutive detections that the operator's network is in a poor signal condition reaches a threshold (for example, 5 times), it indicates the status of the area. The operator's network quality is poor, in order to prevent the terminal from being in a weak signal or no service state for a long time, switch to the next operator's network and switch to the next operator's network at the end of the third period (for example, 30 seconds) Whether the carrier network is in a signal state or not is detected.

The communication module of the present application can detect whether the operator’s network is in a poor signal condition after a relatively long period of time when it detects that the operator’s network that is currently configured to be in use is not in a poor signal condition, so as to maintain While using the operator network with good network quality, the subscriber identification card saves energy consumption of network signal detection; when the communication module detects that the currently used operator network is in a poor signal situation, it will reset after a short period of time The operator's network detects whether it is in poor signal, and when it continuously detects that the number of times that the operator network currently configured as in use is in poor signal reaches the threshold, it will automatically switch to the next operator network, and in the third At the end of the time period, the next operator’s network is automatically detected whether it is in a weak signal state, thereby preventing the current operator’s network from being in a weak signal or no service state for a long time, improving the efficiency of network detection and switching, and improving user experience feel.

In one of the embodiments, as shown in FIG. 3 , the step of detecting whether the target network is in a near-signal state may include:

Step 402, query the value of SINR signal to interference plus noise ratio through AT command;

Step 404, when the value of the SINR signal-to-interference-plus-noise ratio is greater than 0, then confirm that the target network is not in a signal handicap;

Step 406, when the value of the SINR signal-to-interference-plus-noise ratio is less than or equal to 0, it is confirmed that the target network is in a poor signal.

Among them, SINR (Signal to Interference plus Noise Ratio) signal to interference plus noise ratio refers to the ratio of the strength of the received useful signal to the strength of the received interference signal (noise and interference), and the SINR signal to interference plus noise ratio is ground The value can be used as an element to determine the strength of the operator's network signal quality.

Specifically, the communication module queries the value of the SINR signal to interference plus noise ratio (SINR value) by using the AT command "AT+CESQ". The carrier network configured to be in use is not in poor signal quality, and the network quality is good, then the communication module can detect again at the end of the third period whether the operator network currently configured in use state is in poor signal; when the SINR value is less than or equal to 0, it confirms that the target network is in poor signal status, indicating that the currently used operator network is in weak signal or no service state, and the data service performance and communication delay are extremely poor, and the communication module ends in the first period Check again at any time whether the target network is in a signal gap. When the communication module continuously detects that the target network is in a signal gap and the number of times reaches the threshold, it will switch the configuration to the next target network, and at the end of the third period, the next target network The target network performs the detection of whether it is in a signal gap.

This application can use the AT command to query the value of the SINR signal to interference plus noise ratio to determine whether the target network is in a poor signal, so as to determine the signal quality of the operator network that is currently configured to be in use. This method is convenient and practical, combined with this application With a specific cyclic inspection mechanism, the communication module can automatically and accurately detect the quality of the operator's network, switch the operator's network in time when the network quality is detected to be poor, and perform automatic cyclic detection of the signal quality of the next target network to be switched. It ensures the efficiency of network detection and switching, automatically finds high-quality networks, and improves user experience.

In one of the embodiments, as shown in FIG. 4 , before the step of detecting whether the target network is in a signal almost, it may include:

Step 502, checking whether the subscriber identity card has an operator network that is currently configured to be in use, and supports multiple operator networks;

Step 504, when the result of the check is that there is an operator network that is currently configured for use in the subscriber identity card and supports multiple operator networks, then confirm the operator network that is currently configured for use as the target network.

Specifically, before the communication module detects whether the target network is in a poor signal state, it needs to check whether the subscriber identity card has an operator network currently configured for use, and supports multiple operator networks; detects whether the subscriber identity card exists The carrier network currently configured to be in use is to ensure that the subscriber identification card is activated, connected to the network and in use, and prevents network signal detection from being connected to the network without configuration, thereby saving energy consumption for detection. The purpose of checking whether the subscriber identification card supports multiple operator networks is to ensure that the communication module will not be able to connect to the network when it detects that the operator network that is currently configured for use is in poor signal, that is, the signal of the currently used operator network is poor. It can switch to the next operator network and detect the network quality of the next operator network, so that it can automatically find a high-quality network, because when only one operator network is supported, the communication module will It is impossible to switch to the next operator network, and there is no need to detect the signal quality of the operator network.

Therefore, when the communication module detects that the subscriber identity card has an operator network that is currently configured for use, and detects that the subscriber identity card supports multiple operator networks, it will confirm that the operator network that is currently configured for use is The target network, so as to detect whether the target network is in a poor signal; when the communication module detects that the subscriber identity card does not exist, there is no operator network currently configured for use or the subscriber identity card does not support multiple operator networks, then the communication module The module does not detect whether the subscriber identity card is in a signal gap.

In one of the embodiments, the step of checking whether the subscriber identity card has an operator network that is currently configured to be in use and supports multiple operator networks may include:

Check whether there is an electronic account currently configured for use on the user identification card; the electronic account contains information on a single user identification card;

When the result of the check is that there is an electronic account currently configured for use, it is confirmed that there is an operator network currently configured for use, and the number of electronic accounts is queried;

When the result of the query is that the number of electronic accounts is greater than 1, it is confirmed that the subscriber identification card supports multiple operator networks;

When the result of the query is that the number of electronic accounts is less than or equal to 1, it is confirmed that the subscriber identity card does not support multiple operator networks.

Wherein, the eSIM user identification card can usually store multiple electronic account profiles including information of a single user identification card, that is, configuration files. Among them, the profile is used to access the operator's network, and the profile may include integrated circuit card identity (ICCID), international mobile subscriber identity (international mobile subscriber identity, IMSI), authentication key (key identifier, KI ), authentication algorithm, related parameters of network configuration, personal identification number (personal identification number, PIN), unlocking code (PIN unlocking key, PUK), phone number and other parameters. Therefore, when the eSIM user identity card stores multiple profiles, it can switch between the multiple profiles, so as to realize the flexible switching of the operator's network.

Specifically, the communication module judges whether the subscriber identity card has an operator network that is currently configured to be in use by checking whether the subscriber identity card has an electronic account that is currently configured to be in use; If the electronic account is in use, the communication module confirms that the subscriber identity card currently exists in the operator network configured as in use, so that the communication module inquires about the number of electronic accounts stored in the subscriber identity card. When the result of the check is that the user identification card does not have an electronic account that is currently configured to be in use, the communication module confirms that the user identification card does not exist in the operator network that is currently configured to be in use, and there is no need to update the electronic account stored in the user identification card. The number of accounts is queried, thereby saving energy consumption for checking; when the result of the communication module querying the number of electronic accounts stored in the subscriber identification card is that the number of electronic accounts is greater than 1, it is confirmed that the subscriber identification card can support multiple operator networks, In this way, the communication module can support switching configuration to the next operator network when it detects that the currently configured operator network is in poor signal condition, so as to achieve the effect of finding and using a high-quality network; when the communication module queries the electronic If the number of accounts is less than or equal to 1, it is confirmed that the subscriber identity card does not support multiple operator networks, that is, it cannot support the function of switching operator networks, so that it is not necessary to detect the signal quality of the operator network currently configured as in use.

In one of the embodiments, the step of switching to the next target network may include:

Sequence switching configures the next electronic account of the electronic account corresponding to the target network to be in use to access the operator network corresponding to the next electronic account, and determines the operator network corresponding to the next electronic account as the next target network.

Specifically, when the communication module continuously detects that the number of times the target network is in poor signal reaches the threshold, in order to avoid being in a weak signal or no service state for a long time, it switches to the next target network, that is, the communication module can sequentially Bit switching configures the next electronic account of the electronic account corresponding to the target network to be in use, thereby accessing the operator network corresponding to the next electronic account, and confirming the operator network corresponding to the next electronic account as the next target network, and At the end of the third period of time, it is detected whether it is in a signal gap, so that the signal quality of the next target network is also automatically cyclically detected.

In one of the embodiments, as shown in Figure 5, Profile using represents that the communication module judges whether there is an electronic account Profile currently configured as a use state, and when there is no electronic account Profile currently configured as a use state, the detection is ended; If there is an electronic account profile that is currently configured to be in use, the communication module checks the number of profiles, marked as p, and queries whether the number p of profiles is greater than 1. When the communication module inquires that the number p of profiles is less than or equal to 1, the detection ends ;When the communication module finds that the number p of Profiles is greater than 1, it enters the signal cycle detection process, and queries the value of SINR through the "AT+CESQ" command; when the value of SINR is greater than 0, it means that the target network is not in a signal point The module uses a 30-second timer for cyclic detection, that is, at the end of the third period, the communication module detects whether the target network is in a signal gap again; when the value of SINR is less than or equal to 0, the counter is stacked 5 times, that is The communication module detects the SINR value every 5 seconds. When the communication module detects that the SINR value is less than or equal to 0 for 5 consecutive times, it will trigger the sequence switching of the Profile and use Profile (configure the electronic account Profile after the sequence switching ), and re-enter the signal judgment process after the 30-second timer; in the counter superposition stage, when the SINR value is greater than 0 once, the communication module will jump out of the signal cycle detection process and re-enter the signal cycle detection process after the 30-second timer process.

As mentioned above, the present application detects whether the operator network currently configured as in use among the multiple operator networks supported by the subscriber identity card, that is, whether the target network is in a signal gap, and sets the first time period, the second time period and the third time period. Time period, when the communication module detects that the target network is at a signal point, at the end of the first period, it is detected whether the target network is at a signal point, and when the number of times it is detected that the target network is at a signal point reaches a threshold , switch to the next target network, and detect whether the next target network is in a signal gap at the end of the second period, and when the communication module detects that the target network is not in a signal gap, in the third period At the end of the moment, the target network is detected whether it is in a signal gap, so that this application can implement a specific loop detection mechanism to detect the signal quality of the operator network currently configured as in use and perform timely operator network switching. By setting The first time period, the second time period, the third time period and the size of the threshold can effectively save energy consumption for detection. The application also judges the network quality of the operator by querying the value of the SINR signal to the interference-plus-noise ratio through the AT command, and judges whether the electronic account containing the information of a single user identification card is in use and the number of electronic accounts to judge whether there is The carrier network currently configured as in use and whether it supports multiple carrier networks, so as to judge whether the user identification card has the conditions for network signal cycle detection according to the inspection results, and dynamically judge whether it is necessary to switch profiles, and then provide users with high-quality networks. The choice of service and data service experience improves the efficiency of network detection and switching, avoids the terminal being in a weak signal or no service state for a long time, and effectively improves the user experience.

Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders.

In one of the embodiments, the detection module is also used to query the value of the SINR signal to the interference-plus-noise ratio through the AT command; when the value of the SINR signal to the interference-plus-noise ratio is greater than 0, it is confirmed that the target network is not at a signal point; when the SINR If the value of the signal-to-interference-plus-noise ratio is less than or equal to 0, it is confirmed that the target network is in a signal-to-near state.

In one of the embodiments, the first period is less than the second period; the first period is less than the third period;

The operator network switching device also includes:

The check module is used to check whether there is an operator network that is currently configured to be in use on the subscriber identity card, and supports multiple operator networks; If there are no carrier networks, the carrier network that is currently configured to be in use is confirmed as the target network.

In one of the embodiments, the checking module is also used to check whether there is an electronic account that is currently configured for use on the user identification card; the electronic account contains information on a single user identification card; For electronic accounts, confirm that there is an operator network that is currently configured to be in use, and query the number of electronic accounts; if the result of the query is that the number of electronic accounts is greater than 1, then confirm that the user identification card supports multiple operator networks; If the result of the query is that the number of electronic accounts is less than or equal to 1, it is confirmed that the subscriber identity card does not support multiple operator networks.

In one of the embodiments, the detection module is also used to sequentially switch and configure the next electronic account of the electronic account corresponding to the target network to be in use, so as to access the operator network corresponding to the next electronic account, and set the next electronic account The corresponding operator network is determined as the next target network.

For specific limitations on the operator network switching device, refer to the above-mentioned limitations on the operator network switching method, which will not be repeated here. Each module in the above operator network switching device may be fully or partially realized by software, hardware and a combination thereof. The above-mentioned modules can be embedded in or independent of the processor in the computer device in the form of hardware, and can also be stored in the memory of the computer device in the form of software, so that the processor can invoke and execute the corresponding operations of the above-mentioned modules. It should be noted that the division of modules in the embodiment of the present application is schematic, and is only a logical function division, and there may be other division methods in actual implementation.

In one embodiment, a communication module is provided, which is used to implement the above-mentioned operator network switching method.

In one embodiment, as shown in FIG. 6 , a terminal is provided, including the above-mentioned communication module.

Wherein, the terminal can be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices.

Specifically, the terminal may include the above-mentioned communication module for performing the operator network switching method, and when the terminal user with multiple eSIM Profiles is in a weak signal area or an area without network coverage, the operator network switching is performed in a timely manner , allowing users to access a better network.

For example, when a PC (Personal Computer, personal computer) enters a weaker area of the current operator, it first detects whether the user uses the eSIM Profile for data services; Whether it is greater than 1 or not; when the number of electronic account profiles is detected to be greater than 1, use the "AT+CESQ" command to query the SINR value; when the SINR value is less than or equal to 0 when the SINR value is less than or equal to 0 for 5 consecutive queries, the electronic account will be triggered The sequence of the profile is switched, and the signal cycle detection process is restarted 30 seconds after the switching is completed, that is, the "AT+CESQ" command is used to query the SINR value again.

When the PC is in an area with a good signal of the current operator, it will detect whether the user uses the eSIM Profile for data services; If the number of Profiles is greater than 1, use the "AT+CESQ" command to query the SINR value; when the queried SINR value is greater than 0, re-perform the signal cycle detection process after 30 seconds, that is, use the "AT+CESQ" command to query the SINR again value.

When the PC is in a mobile scene, it detects whether the user uses the eSIM Profile for data services; when there is an electronic account profile configured to be used, it detects whether the number of electronic account profiles is greater than 1; when it detects that the number of electronic account profiles is greater than 1, Then use the "AT+CESQ" command to query the SINR value and enter the signal cycle detection process. When the query is continuous for 3 times, each detection is 5 seconds, the SINR value is less than or equal to 0 in the first two queries, and the SINR is found in the third query The value is greater than 0, that is, because the PC terminal moves and finds that the SINR value is greater than 0 in the third query, it will jump out of the signal cycle detection process, and use the "AT+CESQ" command to query the SINR value again after 30 seconds and re-enter the signal cycle detection process .

As mentioned above, when a terminal user with multiple eSIM Profiles is in an area with a weak network signal of an operator or an area without the coverage of the operator's network, the operator network can be switched in a timely manner, which improves the efficiency of operator network detection and switching , It also allows users to access a better operator network, guarantees the performance rate and delay of user data services, and allows end users to obtain a better user experience.
