Detailed Description

In order to make the objects, features and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a method for managing IMS registration, which is applied to an electronic device, wherein the electronic device can be an intelligent terminal such as a smart phone, a tablet computer, wearable equipment and the like. The operating system of the intelligent terminal may be an ios, android, windows system or other operating systems, which is not limited herein.

Referring to fig. 1, the method for managing IMS registration in the present embodiment mainly includes the following steps 101 to 104:

step 101, acquiring network condition information of all networks covering the electronic device when the electronic device is in a starting state, wherein the network condition information is used for representing network conditions of corresponding networks, and all the networks covering the electronic device are from a network provider used by the electronic device;

in this embodiment, the network condition information is information that may reflect network quality, and optionally, the network condition information includes, but is not limited to, at least one of signal strength, signal quality, and upload/download speed. The network in this example includes, but is not limited to, 2G/3G/4G/5G, WiFi, and the like.

In this embodiment, there are various ways for the electronic device to obtain the network status information of all networks covering the electronic device, and optionally, in an example, the electronic device may detect the network status information of all networks covering the electronic device by itself. For example, the electronic device may detect network condition information for all networks (from networks provided by the network provider of the SIM card) that cover itself based on the SIM card installed in itself.

In another example, the electronic device may acquire network information covering all networks of the electronic device from an external information providing device.

In this embodiment, the information providing device may be a mobile terminal such as a mobile phone, a smart band, a tablet computer, or the like, may also be a fixed terminal with a communication function that can detect or store network status information, and may also be a server, and the like, and the present embodiment does not limit the type of the information providing device.

In the present embodiment, the step of acquiring the network status information of all networks of the overlay electronic device from the information providing device is not performed for any network of the overlay electronic device, and the network for which the network status information is acquired originates from the network provider used by the electronic device. Optionally, the network provider used by the electronic device is derived from a network provider corresponding to a SIM card (physical SIM card or virtual SIM card) installed by the electronic device. For example, if the electronic device only installs the SIM card provided by the unicom company, the network status information obtained by the electronic device from the information providing device is originated from the unicom network covering the electronic device, such as the unicom 3G network, the unicom 4G network, and so on. In the electronic device, SIM cards of a plurality of companies are installed, if data traffic and circuit domain services provided by the same network provider (for example, both SIM cards of a mobile company) are provided in the electronic device, the network provider used by the electronic device is the network provider providing the data traffic and the circuit domain services, and if the data traffic and the circuit domain services provided by different network providers are provided in the electronic device, the network provider used by the electronic device is the network provider providing the data traffic and the network provider providing the circuit domain services. It can be understood that, for a multi-card electronic device, network providers providing data traffic service and circuit domain service may be the same or different, and optionally, when acquiring network status information of all networks covering the electronic device, only network status information of a target network may be acquired, where one part of the target network is a network provider providing data traffic for the electronic device, a network supporting IMS service is provided in a network covering the electronic device, and another part is a network provider providing circuit domain service for the electronic device, and a network providing circuit domain service (such as 2G and 3G networks) covering the electronic device is provided.

In this embodiment, the network status information acquired from the information providing apparatus may be already stored in the information providing apparatus before the electronic apparatus acquires the network status information. Therefore, when the electronic device acquires the network condition information, the information providing device can quickly extract the appropriate network condition information from the existing network condition information and send the appropriate network condition information to the electronic device, so that the time for the electronic device to acquire the network condition information is shortened, and the speed for adjusting the IMS registration difficulty is increased. It is understood that, in this embodiment, the network condition information acquired from the information providing apparatus may be detected by the information providing apparatus itself, or may be transmitted to the information providing apparatus after being detected by other apparatuses.

Optionally, for the network condition information acquired from the information providing device, the detection time (the time when the network condition information is detected) and the detection position (the position covered by the network corresponding to the network condition information when the network condition information is detected) need to respectively satisfy the corresponding time condition and position condition, and it can be understood that the closer the detection time is to the time when the electronic device acquires the network condition information, and the closer the detection position is to the position when the electronic device acquires the network condition information, the higher the accuracy of the network condition information is.

In this embodiment, the information providing apparatus may have a plurality of types, such as a mobile terminal, a fixed terminal, a server, and the like, and for different types of information providing apparatuses, different obtaining manners may be adopted to obtain the network status information thereon, and optionally, obtaining the network status information of all networks covering the electronic apparatus from the information providing apparatus includes: network condition information of all networks covering the electronic device is acquired from the information providing device by an acquisition method corresponding to the information providing device according to the type of the information providing device.

In one embodiment, the information providing device is a terminal, and acquiring network status information of all networks covering the electronic device from the information providing device by adopting an acquisition mode corresponding to the information providing device according to the type of the information providing device comprises: network condition information of all networks covering the electronic device is acquired from a terminal which is within a preset distance range from the electronic device, wherein the time difference between the detected time of the network condition information acquired by the electronic device and the current time meets a first preset time difference condition.

When the network providers of the terminal and the electronic device are completely the same and the electronic device and the terminal are close enough (the distance between the terminal and the electronic device is within the preset distance range), it may be considered that the network status of the network covering the electronic device and the network status of the network covering the terminal are the same at the same time, and optionally, when the electronic device and the terminal use the network of the same network provider, acquiring the network status information of all networks covering the electronic device from the terminal whose distance from the electronic device is within the preset distance range includes: and acquiring network condition information of all networks covering the terminal, which is stored by the terminal, from a terminal within a preset distance range from the electronic device, and taking the network condition information as the network condition information of all networks covering the electronic device.

If the electronic device is a multi-card electronic device, and there may be multiple network providers, the network condition information obtained from the information providing device originates from multiple network providers of the electronic device. When the type of the information providing device is a terminal and the electronic device is a multi-card electronic device, network condition information corresponding to networks of different network providers in all networks covering the electronic device is acquired from different terminals when the network condition information of all networks covering the electronic device is acquired from the terminal within a preset distance range, for example, a mobile and a connected SIM card is simultaneously installed on the electronic device, the network condition information of a mobile network covering the electronic device is acquired from a first terminal 20 meters away from the electronic device, and the network condition information of a connected network covering the electronic device is acquired from a second terminal 36 meters away from the electronic device; under the condition that the terminal is also a multi-card terminal and the terminal is the same as a network provider used by the electronic device, network condition information corresponding to networks of different network providers in all networks covering the electronic device can be acquired from the same terminal, for example, a mobile and a communication SIM card is simultaneously installed on the electronic device, a mobile and a communication SIM card is also installed on a certain terminal A, and the distance between the terminal A and the electronic device does not exceed a preset distance range, so that the network condition information of the mobile network covering the electronic device and the network of the communication network are acquired from the terminal A.

Optionally, the electronic device may determine the terminals within a preset distance range from the electronic device in a distance detection manner, and when the number of the determined terminals is greater than 1, the obtaining of the network condition information of all networks covering the terminals, which is stored by the terminal, includes: network condition information of all networks covering the terminal, which is stored by the terminal closest to the electronic device, is acquired. In one example, the distance between the electronic device and the information providing device may be used as the most important condition for measuring the accuracy of the network condition information, and the first preset time difference condition may be: optionally, the obtaining of the network condition information of all networks covering the terminal stored by the terminal includes: and acquiring the network condition information which is stored by the terminal closest to the electronic device and has the detection time closest to the current time. In another example, the time when the network condition information is detected may be used as the most important condition for measuring the accuracy of the network condition information, and the first preset time difference condition may be: the time difference between the detected time of the network condition information acquired by the electronic device and the current time is the shortest. Optionally, the obtaining network condition information of all networks covering the terminal, which is stored by the terminal, includes: and acquiring the network condition information which is stored in the terminal within a preset distance range from the electronic device and has the detected time closest to the current time.

In another embodiment, the information providing device is a server, and the obtaining of the network condition information of all networks covering the electronic device from the information providing device in an obtaining manner corresponding to the information providing device according to the type of the information providing device includes: the electronic device sends the position of the electronic device to the server and receives the network condition information of all the networks covering the position, wherein the time difference between the time when the network condition information received by the electronic device is detected and the time when the electronic device sends the position meets a second preset time difference condition.

Optionally, the server in this embodiment may be a server of a network provider, or a server provided by another company. It is understood that when the server is a server of a network provider, the electronic device sends its location to the server as: the electronic device transmits its own location to a server of a network provider corresponding to each network covering itself. The electronic device receiving the network condition information of all networks covering the position of the electronic device, acquired by the server, includes: the electronic device receives the network status information transmitted from the server of each network provider. When the server is provided by another company, the electronic device only needs to send its own location to the server, and also needs to acquire network status information of all networks covering the electronic device from the server.

In this embodiment, the network condition information in the server may be sent by another electronic device, and when the server searches for the network condition information of all networks covering the location of the electronic device, the server may regard the network condition information in which the distance between the detected location and the location of the electronic device does not exceed the preset distance range as the network condition information of all networks covering the location of the electronic device. In one example, the second preset time difference condition may be: the time difference between the time when the network condition information is detected and the time when the electronic device sends the position satisfies a second preset time difference condition, for example, the time difference does not exceed a preset time difference threshold (e.g., 20 min). Optionally, the network condition information of all networks covering the location of the electronic device sent by the server satisfies the following condition: the distance between the detection position of the network condition information and the position of the electronic device does not exceed a preset distance, and the time difference between the time when the network condition information is detected and the time when the electronic device sends the position to the server does not exceed a preset time difference threshold value. If there are a plurality of network status information satisfying the above conditions in a certain network in the server, such as a mobile 4G network, appropriate network status information may be selected so that the detected position is closest to the position of the electronic device, or the time at which the network status information is detected is closest to the time at which the electronic device transmits the position to the server.

In this embodiment, if the behavior of acquiring the network status information of all networks covering the electronic apparatus from the information providing apparatus fails, the electronic apparatus itself needs to detect the network status information of all networks covering the electronic apparatus itself, and upload the network status information of all networks and the position where the electronic apparatus is located at the time of detection to the server corresponding to each network after the detection. So that the server can share the network state information to the required terminal.

In this embodiment, the method for managing IMS registration further includes: and if the network condition information acquisition requests of other electronic devices are received, transmitting the newly acquired network condition information covering all the networks of the electronic devices to the electronic device initiating the request.

Step 102, determining whether the electronic device is currently in a network supporting an IP multimedia subsystem service, if yes, entering step 103, and if not, returning to step 101;

the networks supporting IP multimedia subsystem services in this embodiment include, but are not limited to, 4G and 5G networks. The electronic device can determine whether the electronic device is currently under the network supporting the IP multimedia subsystem service by searching the network, for example, if the electronic device searches for a 4G network signal, the electronic device is under the network supporting the IP multimedia subsystem service; or, the electronic device determines that the network condition information of the specific network exists in the obtained network condition information, and determines that the electronic device is currently located in the network supporting the IMS service, where the specific network is a network that covers the electronic device and supports the IMS service in a network provided by a network provider that provides data traffic for the electronic device.

In one example, optionally, determining whether the electronic device is currently under a network supporting IP multimedia subsystem services comprises: when a trigger network exists in a network covering the electronic device, determining whether the electronic device is currently under a network supporting an IP multimedia subsystem service, wherein the trigger network is a network in which the change of the current network condition information relative to the last detected network condition information meets the change requirement. The scheme can avoid the problem of frequently adjusting the registration difficulty of the IP multimedia subsystem of the electronic device when the network changes little, and avoid more consumption of the electronic device.

In the above example, the change requirement may be: the signal quality and/or signal strength varies by more than the corresponding range of variation, e.g., the signal strength decays by more than half the last signal strength. The trigger network may be a 2G, 3G, 4G, and 5G network, etc., which is not limited in this embodiment.

103, acquiring physical environment information around the electronic device;

in this step, acquiring physical environment information around the electronic device includes: physical environment information within a preset range (such as within a range of 200 meters) from the electronic device is acquired. Optionally, the electronic device may obtain physical environment information within a preset range from data providing devices distributed around the electronic device; or the electronic device detects the physical environment information within a preset distance range through a detection module of the electronic device.

In this embodiment, the physical environment information includes, but is not limited to, location information, shelter information, altitude information, and base station concentration information of a network provider used by the electronic device, and the like.

And 104, determining network quality evaluation methods of all networks in the current physical environment of the electronic device according to the physical environment information, and adjusting the difficulty of registering the IP multimedia subsystem of the electronic device based on the network quality evaluation methods and the network condition information.

It can be understood that, if the electronic device is currently under the IP multimedia subsystem supporting network (e.g. 4G or 5G), that is, the IP multimedia subsystem supporting network in the network provider network used by the electronic device covers the terminal, the electronic device will generally access the network with the best signal (generally, a higher-standard network) in the IP multimedia subsystem supporting network.

In this embodiment, different physical environment information may have different network quality evaluation methods, and in different environments, the network quality evaluation method may be used to evaluate the network quality of each network in the network covering the electronic device in the physical environment where the electronic device is currently located.

Optionally, when the difficulty of registering the IP multimedia subsystem by the electronic device is adjusted based on the network quality evaluation method and the network condition information, the network quality of the networks may be analyzed based on the network quality evaluation method in the current physical environment and the network condition information of all networks currently covering the electronic device, and the difficulty of registering the IP multimedia subsystem by the electronic device may be adjusted according to the analysis result.

Alternatively, in one example, the network quality may be specific to the quality of the IP multimedia subsystem service.

Optionally, analyzing the network quality of the networks based on the network quality evaluation method in the current physical environment and the network condition information of all networks currently covering the electronic device, and adjusting the difficulty of registering the IP multimedia subsystem in the electronic device according to the analysis result includes: and analyzing the quality of the IP multimedia subsystem service under the network supporting the IP multimedia subsystem service in all networks based on the network quality evaluation method and the network condition information, and adjusting the difficulty of registering the IP multimedia subsystem by the electronic device according to the analysis result.

Optionally, the analysis of the quality of the IP multimedia subsystem service in the network supporting the IP multimedia subsystem service may be obtained based on a comparison analysis of the quality of the IMS service in the network supporting the IP multimedia subsystem service with the quality of networks in other networks covering the electronic device. For example, if the quality of the IP multimedia subsystem service is not lower than the first quality standard in the network supporting the IP multimedia subsystem service, the difficulty of registering the IP multimedia subsystem by the electronic device is reduced; if the quality of the IP multimedia subsystem service is lower than the first quality standard but higher than the second quality standard under the network supporting the IP multimedia subsystem service, the difficulty of registering the IP multimedia subsystem by the electronic device is improved; and if the quality of the IP multimedia subsystem service under the network supporting the IP multimedia subsystem service is not higher than the second quality standard, determining how to adjust the difficulty of registering the IP multimedia subsystem by the electronic device according to the network quality under each network not supporting the IMS service.

In an example, the quality of the IP multimedia subsystem service may be specifically call quality, and the quality of the IP multimedia subsystem service in the network supporting the IP multimedia subsystem service in all networks is analyzed based on the network quality evaluation method and the network condition information, which may be understood as analyzing the call quality in the IMS service in the network supporting the IP multimedia subsystem service in all networks and the call quality in the network not supporting the IP multimedia subsystem service in the overlay electronic device based on the network quality evaluation method and the network condition information of all networks overlaying the electronic device.

In this embodiment, a network supporting the IP multimedia subsystem in the network where the network condition information is obtained may be classified into a first type of network, and a network not supporting the IP multimedia subsystem (or a network supporting the circuit domain service) may be classified into a second type of network.

Analyzing the network quality of each network in all the networks, and adjusting the difficulty of registering the IP multimedia subsystem by the electronic device according to the analysis result may be: comparing the network quality of a network (network A) with poor quality in a first type of network covering the electronic device with the network (network B) with the best quality in a second type of network covering the electronic device; if the network quality of the former (network a) is better, the difficulty of registering the IP multimedia subsystem by the electronic device can be properly reduced, so that the call service is realized by the IMS with better service quality as much as possible, and if the network quality of the latter (network B) is better, the difficulty of registering the IP multimedia subsystem can be properly increased, so that when the network quality supporting the IP multimedia subsystem service does not meet the requirement, the IMS registration cannot be successful, so that the call service can be realized on the circuit domain with better service quality. Optionally, the higher the network quality of the network a is than that of the network B, the larger the reduction amplitude of the difficulty of registering the IMS system by the electronic device is, the lower the network quality of the network a is than that of the network B, and the larger the improvement amplitude of the difficulty of registering the IMS system by the electronic device is.

Optionally, in this embodiment, three quality levels, namely a first quality level, a second quality level, and a third quality level, may be set for the quality of each network in the networks supporting the IMS service in all networks covering the electronic device, and two levels, namely a fourth quality level and a fifth quality level, may be set for the quality of each network in all networks not supporting the IMS service; wherein, each different quality grade can correspond to different signal quality and different signal intensity; a network of a first quality level is better than a network of a second quality level, which is better than a network of a third quality level. The network of the fourth quality level is superior to the network of the fifth quality level. According to the network quality evaluation method of each network, the network quality grade of the evaluated network can be obtained. For example, in this embodiment, the network quality evaluation method for the metropolitan area is set to the content shown in table 1:

TABLE 1

It should be noted that, in the above table, the ranges of signal quality and signal strength corresponding to the same quality class of different networks may be the same or different, for example, the first signal strength threshold in the first quality classes of 4G and 5G in the above table is the same, and the first signal quality threshold in the first quality classes of 4G and 5G is different.

It is understood that the signal strength range and/or the signal quality range corresponding to the quality level set in table 1 are only for illustration, and there is no limitation on the signal strength range and/or the signal quality range corresponding to the quality level set in the present embodiment. In table 1 above, the first, second, third, and fourth amplitudes may be different.

Optionally, the network condition information in this example includes, but is not limited to, signal quality and signal strength, and the network quality of each network may be measured by the signal strength and/or signal quality of the network.

Optionally, analyzing the quality of the IP multimedia subsystem service in the network supporting the IP multimedia subsystem service in all networks based on the network quality evaluation method and the network condition information, and adjusting the difficulty of registering the IP multimedia subsystem by the electronic device according to the analysis result includes:

acquiring signal intensity thresholds and signal quality thresholds corresponding to networks supporting the IP multimedia subsystem service in all networks and acquiring signal intensity thresholds corresponding to networks not supporting the IP multimedia subsystem service in all networks based on a network quality evaluation method;

if the signal strength of at least one network is not lower than the corresponding signal strength threshold value in the networks supporting the IP multimedia subsystem service in all the networks, judging whether the network with the signal quality not lower than the corresponding signal quality threshold value exists in the at least one network, if so, reducing the difficulty of registering the IP multimedia subsystem by the electronic device, and if not, improving the difficulty of registering the IP multimedia subsystem by the electronic device;

if the signal intensity of each network in all the networks supporting the IP multimedia subsystem service is lower than the corresponding signal intensity threshold value, judging whether a high-quality network exists in the networks which do not support the IP multimedia subsystem service in all the networks, if so, improving the difficulty of registering the IP multimedia subsystem by the electronic device, and if not, reducing the difficulty of registering the IP multimedia subsystem by the electronic device, wherein the high-quality network is a network of which the signal intensity is not lower than the corresponding signal intensity threshold value.

The following describes how to adjust the registration difficulty of the IP multimedia subsystem by taking an electronic device supporting both 4G and 5G networks as an example. Assuming that the current network used by the electronic device is the 5G network of the mobile company, the signal strength of the 5G network is lower than the first signal strength threshold corresponding to the 5G network in table 1, but the electronic device is still under the coverage of the 4G network of the mobile company, an IMS registration difficulty adjustment policy is determined according to the signal strength and the signal quality of the 4G network to adjust the difficulty of the electronic device in registering the IMS. Specifically, if the signal strength and the signal quality of the 4G network covering the electronic device are not lower than a first signal strength threshold and a first signal quality threshold corresponding to the 4G network in table 1, respectively, the IMS registration difficulty is reduced, if the signal strength of the 4G network is not lower than the first signal strength threshold and the signal quality is lower than the first signal quality threshold, the IMS registration difficulty is increased, and if the signal strength of the 4G network is lower than the first signal strength threshold, the IMS registration difficulty of the electronic device is adjusted based on the network quality of a network that does not support IMS services in the network covering the electronic device.

Optionally, the network quality evaluation method may be read locally by the electronic device, or may be obtained from a server by the electronic device.

Optionally, in this embodiment, a plurality of different physical environment information may be preset, and a network quality evaluation method for a network may be set in each physical environment, and optionally, the method for determining network quality evaluation of all networks in the current physical environment of the electronic device according to the physical environment information includes: and determining the network quality evaluation methods of all networks in the current physical environment of the electronic device according to the corresponding relation between the preset physical environment information and the network quality evaluation methods and the acquired physical environment information.

In one example, the physical environment information may be a specific geographic location, for example, each province in the country is divided into one physical environment, and the physical environment information acquired by the electronic device is information of a provincial administrative unit in which the electronic device is located; or, each market in the country is divided into one physical environment, and the physical environment information acquired by the electronic device is information of the administrative unit at the city level where the electronic device is located. Optionally, the method for determining the network quality evaluation of all networks in the current physical environment of the electronic device according to the corresponding relationship between the preset physical environment information and the network quality evaluation method and the acquired physical environment information includes: and determining the network quality evaluation methods of all networks in the current geographical position of the electronic device according to the corresponding relation between the preset geographical position and the network quality evaluation method and the acquired geographical position of the electronic device.

In one example, the physical environment information may be an obstruction condition within a preset range from the electronic device, for example, a condition that no building with a height of more than 140 meters exists within a range of 300 meters from the electronic device is set as the physical environment information, and the physical environment information acquired by the electronic device is the height of the highest building within a range of 300 meters from the electronic device. Optionally, the method for determining the network quality evaluation of all networks in the current physical environment of the electronic device according to the corresponding relationship between the preset physical environment information and the network quality evaluation method and the acquired physical environment information includes: and determining the network quality evaluation methods of all the networks under the condition of the shielding object according to the corresponding relation between the preset shielding object condition and the network quality evaluation method and the acquired shielding object condition within the preset range from the electronic device.

Optionally, the shielding condition within the preset range from the electronic device may also be the building density within the preset range from the electronic device, and the like. Optionally, in an example, the physical environment information may also be a concentration of base stations within a preset range from the electronic device, and the like.

In this embodiment, when the difficulty of registering the IP multimedia subsystem in the electronic device is adjusted, the preset highest IMS registration difficulty and the preset lowest IMS registration difficulty may also be referred to.

Optionally, before adjusting the difficulty of registering the IP multimedia subsystem in the electronic device, the method further includes: after the difficulty adjustment is carried out on the electronic device registration IP multimedia subsystem, whether the difficulty of registering the IP multimedia subsystem is in the range from the highest IMS registration difficulty to the lowest IMS registration difficulty is judged, if yes, the adjustment is carried out, otherwise, the adjustment is abandoned, or if the difficulty of registering the IP multimedia subsystem on the electronic device is higher than the highest IMS registration difficulty, the difficulty of registering the IP multimedia subsystem on the electronic device is adjusted to the highest IMS registration difficulty, and if the difficulty of registering the IP multimedia subsystem on the electronic device is lower than the lowest IMS registration difficulty, the difficulty of registering the IP multimedia subsystem on the electronic device is adjusted to the lowest IMS registration difficulty, so that the condition that the IMS registration difficulty is too high or too low can be avoided, and the IMS service quality such as call quality can be ensured. In one example, different maximum and minimum IMS registration difficulties may be set for different network providers, respectively.

Optionally, in this embodiment, the difficulty of registering the IMS by the electronic device may be adjusted in a plurality of ways, for example, by setting or modifying some parameters on the electronic device, the difficulty of registering the IP multimedia subsystem by the electronic device is adjusted; or, through the communication of the electronic device with the operator server, the operator server is enabled to modify the difficulty of the electronic device for registering the IMS according to the indication of the electronic device, and the like.

Optionally, the method for adjusting the difficulty of registering the IP multimedia subsystem by the electronic device includes:

if the difficulty of registering the IP multimedia subsystem by the electronic device needs to be improved, the registration threshold value of the IP multimedia subsystem set on the electronic device is improved;

if the difficulty of registering the IP multimedia subsystem by the electronic device needs to be reduced, the registration threshold value of the IP multimedia subsystem set on the electronic device is reduced.

It is understood that, in addition to modifying the IP multimedia subsystem registration threshold set on the electronic device, the present embodiment may also adopt other feasible means to adjust the difficulty of the electronic device registering the IMS.

It can be understood that, the electronic device acquires the network condition information of each network in all the networks covering the electronic device for a plurality of times in each day, which is beneficial for the electronic device to better grasp the change situation of the available network. In practical use of an electronic device, when the mobile electronic device such as a smart phone, a tablet computer, and a wearable device moves along with a user, the mobile electronic device often faces a problem of network signal change due to a change in geographic location. For example, if a user enters a region with dense shelters from an open area, the network signal generally deteriorates, and even a 4G switch to 3G/2G switch occurs. Obtaining the network condition information multiple times is beneficial to helping the electronic device to deal with the problems caused by network changes.

In this embodiment, the network status information may be acquired by setting a time interval. Optionally, the obtaining network condition information of all networks covering the electronic device includes: and determining rules according to the preset acquisition time, and acquiring the network condition information of all networks covering the electronic device when the acquisition time is up. The preset acquisition time determination rule in this example may be used to determine a specific time for acquiring network status information of all networks covering the electronic device.

In one example, the preset acquiring time determining rule may be: the interval duration between two adjacent acquisition moments is the same preset time interval. That is, according to the preset acquisition time determination rule, acquiring the network condition information of all networks covering the electronic device when the acquisition time arrives includes: and determining the current acquisition time according to a preset time interval and the last acquisition time, and acquiring the network condition information of all networks covering the electronic device when the current acquisition time is reached.

The preset time interval may be set according to actual needs, for example, the preset time interval may be 30min, and the network condition information of all networks covering the electronic device is acquired once every 30min when the electronic device is in the power-on state.

In this embodiment, the first acquiring of the network condition information of all networks covering the electronic apparatus may be performed after the electronic apparatus is turned on, and a time duration between each subsequent time of acquiring the network condition information and a last time of acquiring the network condition information is a preset time interval.

In another example, the preset acquisition time determination rule may be: the time of day is divided into different time periods, and each time period corresponds to a preset time interval. Optionally, determining a rule according to a preset obtaining time, and obtaining network status information of all networks covering the electronic device when the obtaining time is reached includes: and determining the acquisition time of the current time according to the corresponding relation between the time period and the preset time interval and the time of acquiring the network condition information of all networks covering the electronic device at the latest time, and acquiring the network condition information of all networks covering the electronic device when the acquisition time arrives.

After each acquisition, the preset time interval corresponding to the time period to which the acquired time belongs may be added to the acquisition time of the network condition information, so as to obtain the next acquisition time. In this example, the correspondence relationship between the time periods and the preset time intervals may be stored in the electronic device in a table form, for example, the correspondence relationship table between the time periods and the preset time intervals is shown in table 2:

time period	Preset time interval
		0:00-8:00	2h
8:00-12:00	1h
		12:00-14:00	30min
14:00-18:00	1h
		18:00-24:00	30min

TABLE 2

According to the above table, if the current acquisition time is 11:40, the next acquisition time is 11: one hour after 40, 12: 40.

Furthermore, for different dates, different time periods and corresponding preset time intervals can be further divided. For example, on weekdays, i.e., monday through friday, the preset time interval may be set according to the time period in table 2 above, while on saturday and sunday, the preset time interval may be directly set to 30 min. So as to meet the requirements of users on different dates.

In another example, the preset acquisition time determination rule may be: if the current time is the preset acquisition time, the current time is the acquisition time for acquiring the network condition information of all the networks covering the electronic device. Optionally, determining a rule according to a preset obtaining time, and obtaining network status information of all networks covering the electronic device when the obtaining time is reached includes: and if the current time is the preset acquisition time, acquiring the network condition information of all networks covering the electronic device. For example, the preset acquisition time may be fixed at 8:00,12:00,14:00,16:00, and 20:00 for each day.

In another example, the preset acquisition time determination rule may be set based on a moving distance of the electronic device, for example, the preset acquisition time determination rule may be: if the distance between the current position of the electronic device and the last acquired position of the electronic device exceeds a preset distance threshold, the current time is the acquisition time, wherein the acquisition position is the position of the electronic device when the network condition information of all networks covering the electronic device is acquired. Optionally, determining a rule according to a preset obtaining time, and obtaining network status information of all networks covering the electronic device when the obtaining time is reached includes: and when the distance between the current position of the electronic device and the last acquired position of the electronic device exceeds a preset distance threshold, acquiring network condition information of all networks covering the electronic device. The preset distance threshold may be set according to actual needs, for example, to 1 km.

In another example, the preset obtaining time determination rule may be set based on the surrounding environment of the electronic device, for example, the preset obtaining time determination rule may be: and if the environment around the electronic device does not meet the preset requirement at the current moment, the current moment is the acquisition moment. The preset requirement may be that there is no preset obstacle within a preset radius from the electronic device.

Optionally, determining a rule according to a preset obtaining time, and obtaining network status information of all networks covering the electronic device when the obtaining time is reached includes: the method comprises the steps of obtaining information of the surrounding environment of the electronic device, and obtaining network condition information of all networks covering the electronic device when the surrounding environment of the electronic device does not meet preset requirements. Optionally, the obtaining information of an environment around the electronic device, and when the environment around the electronic device does not meet a preset requirement, the obtaining network condition information of all networks covering the electronic device includes: the method comprises the steps of obtaining the height of the highest building within a preset radius from the periphery of the electronic device, and obtaining network condition information of all networks covering the electronic device if the height exceeds a preset height threshold value.

Therefore, in this embodiment, when the difficulty of registering the IP multimedia subsystem is adjusted, the physical environment information of the electronic device and the network conditions in multiple systems are taken into consideration, so that the situation that the registration condition of the IMS is disjointed from the physical environment where the electronic device is located and the network conditions of each network in the physical environment is avoided.

In another example, an event that the RAT network changes may also be detected in the event that the modem actively reports, and if the event that the RAT network changes is detected, it is indicated that there is a network change in the RAT network.
