In one embodiment, as shown in fig. 1, there is provided an operator network handover method, which may include:
step 202, detecting whether a target network is at a signal difference point; the target network is an operator network which is currently configured to be in a use state in a plurality of operator networks supported by the subscriber identity module;
and 204, if the detection result is that the target network is at the signal difference point, detecting whether the target network is at the signal difference point at the moment when the first time period ends, switching to the next target network under the condition that the frequency of continuously detecting that the target network is at the signal difference point reaches a threshold value, and detecting whether the next target network is at the signal difference point at the moment when the second time period ends.
The network is in a weak signal or no service state, and the data service performance and the communication delay of the network are extremely poor; the first time interval and the second time interval can be adjusted according to actual conditions, for example, the first time interval can be smaller than the second time interval; by adjusting the first time period and the second time period, the interval time for detecting whether the target network is at the signal difference point can be changed; the threshold value can also be adjusted according to the actual situation, and the interval time for switching the next target network can be changed by adjusting the threshold value.
Specifically, whether the currently used operator network is in a weak signal state or a no-service state is judged by detecting whether the operator network currently configured to be in the use state in a target network, namely a plurality of operator networks supported by a Subscriber Identity Module (SIM) card is in a signal difference point; if the detection result shows that the target network is at a signal difference point, which indicates that the currently used operator network (i.e. the operator network currently configured to be in a use state) is in a weak signal state or a no-service state, detecting whether the target network is at the signal difference point again at the time when the first period ends, confirming whether the currently used operator network is in the signal difference point again, switching to the next target network in order to prevent the target network from being in the weak signal state or the no-service state for a long time under the condition that the frequency of continuously detecting that the target network is at the signal difference point reaches a threshold value, and detecting whether the next target network is at the signal difference point at the time when the second period ends. Therefore, the method and the device carry out automatic cycle detection on the currently used target network by setting a first time interval and a second time interval, the frequency of continuously detecting that the target network is at a signal difference point reaches a threshold value indicates that the target network can be in a weak signal or no-service state for a long time, so that the next target network is switched, and whether the next target network is at the signal difference point is detected at the moment when the second time interval is ended, so that a specific cycle detection mechanism is formed, the operator network with good network quality is automatically searched, and the condition that the operator network configured to be in a use state is in the weak signal or no-service state for a long time is avoided.
The method can be realized as an end user provided with a subscriber identity module card supporting a plurality of operator networks, detect the signal quality of the currently used operator network by a specific cycle detection mechanism, detect whether the target network is at the signal difference point again at the end of a first period when the operator network currently configured to be in use is detected to be in a weak signal or no service state, namely, the target network is at the signal difference point, confirm whether the target network is still at the signal difference point, and switch to the next target network when the number of times of continuously detecting that the target network is at the signal difference point reaches a threshold value, namely switch to the next operator network when the operator network currently configured to be in use is confirmed to be in a weak signal or no service state for a long time, and automatically cycle detect the signal quality of the next operator network, therefore, a high-quality network is automatically searched, when a terminal user is in an area with weak network signals of an operator or an area without network coverage of the operator, network switching of the operator is timely performed, the user is enabled to access a better network, network switching efficiency is improved, the terminal is prevented from being in a weak signal state or a no-service state for a long time, performance rate and time delay of user data services are guaranteed, and user experience is effectively improved.
In one embodiment, as shown in fig. 2, the operator network handover method may further include:
step 302, if the detection result is that the target network is not at the signal difference point, detecting whether the target network is at the signal difference point at the time when the third time period ends.
In one particular example, the first period of time is less than the second period of time; the first period is less than the third period.
Specifically, if the detection result is that the target network is not in a signal difference point, it indicates that the signal quality of the target network is good, and the target network is not in a weak signal or no service state, and the target network is detected again at the time of the end of the third time period, so that when the signal quality of the operator network currently configured in the use state is detected to be good, the signal quality of the operator network is continuously and automatically detected in a loop manner, so as to ensure that the operator network currently used is a good-quality network until the target network is detected to be in the signal difference point, and then whether the target network is in the signal difference point is detected at the time of the end of the first time period, and when the number of times of continuously detecting that the target network is in the signal difference point reaches the threshold value, the next target network is switched to. The first time period is less than the second time period, and the first time period may also be less than the third time period, for example, the first time period may be 5 seconds, and the second time period and the third time period may be 30 seconds, so that when it is detected that the target network is not at the signal difference point, the signal detection may be performed on the operator network after a longer time interval, thereby saving energy consumption, and when it is detected that the target network is at the signal difference point, the target network may be detected again at a shorter time interval, thereby preventing the operator network from being in a weak signal or no service state for a long time, performing the switching use of the operator network in time, and performing the signal quality detection on the next switched target network again at a longer time interval.
For example, when an end user having a subscriber identity card supporting multiple operator networks uses a certain operator network, the quality of the operator network is good, the signal quality of the operator network is automatically and continuously detected at long time intervals (for example, 30 seconds), if the end user moves to another area, the quality of the operator network is very weak in the area, if the end user detects that the operator network is at a signal difference point, whether the operator network is at the signal difference point is automatically detected again at short time intervals (for example, 5 seconds), if the number of times of continuously detecting that the operator network is at the signal difference point reaches a threshold value (for example, 5 times), the quality of the operator network in the area is poor, and in order to prevent the terminal from being in a weak signal or out-of-service state for a long time, the end user switches to be configured to the next operator network, and detects at the end of the third period of time (e.g., 30 seconds) whether the next operator network is at a signal difference point.
The method and the device can detect whether the operator network is in the signal difference point after a long period of time is over under the condition that the operator network which is currently configured to be in the use state is not in the signal difference point, so that the user identification card is kept using the operator network with good network quality, and meanwhile, the energy consumption of network signal detection is saved; under the condition that the currently used operator network is detected to be at the signal difference point, whether the operator network is at the signal difference point is detected after a short period of time is ended, and under the condition that the frequency of continuously detecting that the currently configured operator network in the use state is at the signal difference point reaches a threshold value, the next operator network is automatically switched to use, and whether the next operator network is at the signal difference point is automatically detected at the moment that a third period of time is ended, so that the currently used operator network is prevented from being in a weak signal or non-service state for a long time, the network detection switching efficiency is improved, and the user experience is improved.
In one embodiment, as shown in fig. 3, the step of detecting whether the target network is at the signal difference point may include:
step 402, inquiring the value of the SINR signal to interference plus noise ratio through an AT instruction;
step 404, if the value of the SINR signal to interference plus noise ratio is greater than 0, determining that the target network is not at a signal difference point;
in step 406, if the value of the SINR signal to interference plus noise ratio is less than or equal to 0, it is determined that the target network is at a signal difference point.
The SINR (signal to Interference plus Noise ratio) is a ratio of the strength of the received useful signal to the strength of the received Interference signal (Noise and Interference), and the SINR plus Noise ratio can be used as a determination factor for determining the signal quality of the operator network.
Specifically, by using the AT instruction "AT + CESQ" to query a value of SINR signal to interference plus noise ratio (SINR value), if the SINR value is greater than 0, it is determined that the target network is not AT a signal difference point, which indicates that the operator network currently configured as the use state by the subscriber identity card is not AT the signal difference point, and the network quality is good, and then it may be detected again AT the time when the third time period ends whether the operator network currently configured as the use state is AT the signal difference point; if the SINR value is less than or equal to 0, determining that the target network is at a signal difference point, which indicates that the currently used operator network is at the signal difference point, i.e., in a weak signal or no service state, and the data service performance and the communication delay are extremely poor, detecting whether the target network is at the signal difference point again at the time when the first period ends, switching to configure the target network as the next target network under the condition that the number of times that the target network is continuously detected to be at the signal difference point reaches a threshold value, and detecting whether the next target network is at the signal difference point at the time when the third period ends.
The method can use the AT instruction to inquire the SINR signal and interference plus noise ratio value to judge whether the target network is AT a signal difference point, thereby judging the signal quality of the operator network configured to be in a use state AT present, the method is convenient and practical, the method can automatically and accurately detect the network quality of the operator by combining with a specific circulation checking mechanism, the operator network can be timely switched under the condition of detecting the poor network quality, automatic circulation detection is carried out on the signal quality of the next target network switched, the efficiency of network detection switching is ensured, a high-quality network is automatically searched, and the user experience is improved.
In one embodiment, as shown in fig. 4, before the step of detecting whether the target network is at the signal difference point, the method may include:
step 502, checking whether the user identification card has an operator network configured in a use state currently and supports a plurality of operator networks;
step 504, if the checking result indicates that the subscriber identity module card has the operator network currently configured as the use state and supports a plurality of operator networks, determining the operator network currently configured as the use state as the target network.
Specifically, before detecting whether a target network is at a signal difference point, it is required to check whether an operator network currently configured in a use state exists in a subscriber identity module, and to support multiple operator networks; whether the operator network configured to be in the use state currently exists in the subscriber identity module is detected to ensure that the subscriber identity module is activated, connected with the network and in the use state, so that network signal detection is prevented from being performed in the state that the network is not configured and connected, and detection energy consumption can be saved. The reason for checking whether the subscriber identity card supports multiple operator networks is to ensure that when it is detected that the operator network currently configured in a use state is at a signal difference point, that is, when the operator network currently used is poor in signal, the operator identity card can be switched to the next operator network and detect the network quality of the next operator network, so that a high-quality network can be automatically searched.
Therefore, when the user identification card is detected to have the operator network which is currently configured to be in the use state, and the user identification card is detected to support a plurality of operator networks, the operator network which is currently configured to be in the use state is confirmed to be the target network, so that whether the target network is in a signal difference point is detected; if it is detected that the subscriber identity card does not have the operator network currently configured as the use state or the subscriber identity card does not support a plurality of operator networks, the subscriber identity card is not detected whether the subscriber identity card is at a signal difference point.
In one embodiment, the step of checking whether the subscriber identity card has an operator network currently configured in a use state and supporting a plurality of operator networks may include:
checking whether the user identification card has an electronic account which is currently configured to be in a use state; the electronic account contains information of a single user identification card;
if the checked result is that the electronic account which is currently configured as the use state exists, confirming that the operator network which is currently configured as the use state exists, and inquiring the number of the electronic accounts;
if the number of the electronic accounts is larger than 1 as a result of the query, confirming that the user identification card supports a plurality of operator networks;
and if the number of the electronic accounts is less than or equal to 1 as a result of the query, confirming that the user identification card does not support a plurality of operator networks.
The eSIM subscriber identity card can generally store a plurality of electronic account profiles, i.e., configuration files, containing information of a single subscriber identity card. The profile is used for accessing to an operator network, and may include parameters such as an integrated circuit identifier (ICCID), an International Mobile Subscriber Identifier (IMSI), an authentication Key (KI), an authentication algorithm, parameters related to network configuration, a Personal Identification Number (PIN), an unlock code (PUK), and a phone number. Therefore, when the eSIM subscriber identity card stores a plurality of profiles, it is possible to implement flexible switching of the operator network by switching among the plurality of profiles.
Specifically, whether the user identification card has the operator network which is currently configured to be in the use state is judged by checking whether the user identification card has the electronic account which is currently configured to be in the use state; and if the checked result is that the user identification card has the electronic account which is currently configured to be in the use state, confirming that the user identification card currently has the operator network which is configured to be in the use state, and then inquiring the number of the electronic accounts stored in the user identification card. If the checked result is that the user identification card does not have the electronic account which is currently configured as the use state, the fact that the user identification card does not have the operator network which is currently configured as the use state is confirmed, and the number of the electronic accounts stored in the user identification card does not need to be inquired, so that checking energy consumption is saved; if the result of inquiring the number of the electronic accounts stored in the user identification card is that the number of the electronic accounts is more than 1, confirming that the user identification card can support a plurality of operator networks, so that the switching configuration of the operator network in the current configuration use state to the next operator network can be supported under the condition of detecting that the operator network is at a signal difference point, and further realizing the effect of searching and using a high-quality network; if the number of the electronic accounts is inquired to be less than or equal to 1, the user identification card is confirmed to not support a plurality of operator networks, namely, the function of switching the operator networks cannot be supported, so that the signal quality of the operator network configured to be in the use state at present does not need to be detected.
In one embodiment, the step of switching to the next target network may include:
and configuring the next electronic account of the electronic account corresponding to the target network as a use state by the order switching so as to access the operator network corresponding to the next electronic account, and determining the operator network corresponding to the next electronic account as the next target network.
Specifically, under the condition that the number of times that the target network is continuously detected to be at the signal difference point reaches the threshold value, in order to avoid being in a weak signal state or no service state for a long time, the target network is switched to the next target network, that is, the next electronic account corresponding to the target network can be configured to be in a use state by means of cis-position switching, so as to access the operator network corresponding to the next electronic account, the operator network corresponding to the next electronic account is determined to be the next target network, and whether the operator network is at the signal difference point is detected at the time when the third time period ends, so that the signal quality of the next target network is also subjected to corresponding automatic cycle detection.
In a specific embodiment, as shown in fig. 5, the Profile using represents that whether the electronic account Profile currently configured as the use state exists is determined, and if the electronic account Profile currently configured as the use state does not exist, the detection is ended; if the electronic account Profile which is currently configured as the use state exists, checking the number of the profiles, marking the number as p, inquiring whether the number p of the profiles is more than 1, and if the number p of the profiles is less than or equal to 1, finishing the detection; if the number p of profiles is larger than 1, entering a signal cycle detection process, and inquiring the SINR value through an AT + CESQ command; if the SINR value is greater than 0, which indicates that the target network is not at the signal difference point, performing cycle detection with a 30-second timer, that is, detecting whether the target network is at the signal difference point again at the time when the third time period ends; if the SINR value is less than or equal to 0, the counter is overlapped for 5 times, namely the SINR value is detected every 5 seconds, if the SINR value is detected for 5 times continuously and is less than or equal to 0, the sequence switching and use of the Profile (the electronic account Profile after the sequence switching is configured and used) is triggered, and the signal judgment process is entered again after the timer of 30 seconds; and in the counter superposition stage, if the SINR value is greater than 0 once, jumping out of the signal cycle detection process, and re-entering the signal cycle detection process after a timer of 30 seconds.
In the above, the present application may implement signal quality detection on an operator network currently configured as a use state among a plurality of operator networks supported by a subscriber identity module, that is, by detecting whether a target network is at a signal difference point, and setting a first time period, a second time period, and a third time period, detecting whether the target network is at the signal difference point at the time when the first time period ends when the target network is detected to be at the signal difference point, and switching to a next target network when the number of times the target network is detected to be at the signal difference point reaches a threshold, and detecting whether the target network is at the signal difference point at the time when the second time period ends, and detecting whether the target network is at the signal difference point at the time when the third time period ends when the target network is detected to be not at the signal difference point, so that the present application may implement signal quality detection on the operator network currently configured as the use state by using a specific loop detection mechanism And the detection and the timely switching of the operator network are carried out, and the detection energy consumption can be effectively saved by setting the first time period, the second time period, the third time period and the threshold value.
