Background
With the continuous development of network technology, the services carried on the network are more and more, which brings more convenience to people. For example, the 4G network, which is now widely used, supports IP Multimedia Subsystem (IMS) services, where IMS is a Multimedia control/call control platform on a packet domain, and the IMS enables the packet domain to have part of functions of a circuit domain and supports conversational and non-conversational Multimedia services.
However, IMS cannot completely replace the circuit domain, so in practice, with the widespread use of IMS, handover between IMS and circuit domain is very important. Currently, a general scheme is that a terminal registers an IMS in a network supporting an IMS service, such as 4G or 5G; when switching from a 4G or 5G network to a 3G network and a 2G network with lower standards, a terminal is switched from an IMS to a circuit domain, but in the scheme, the IMS registration condition is rigid, flexible switching between the IMS and the circuit domain is not facilitated, and the problem of call quality caused by poor network state is easy to occur.

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 103:
step 101, when the electronic device is in a power-on state, network condition information of all networks covering the electronic device is obtained from an information providing device, wherein the network condition information is used for representing network conditions of corresponding networks;
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 covering the electronic device from the information providing device is not performed for any network covering the electronic device, and the network for which the network status information is acquired originates from the network provider used by the electronic device. For example, if the electronic device currently uses a SIM card provided by a unicom company, the network condition information obtained by the electronic device from the information providing device is originated from a unicom network covering the electronic device, such as a unicom 3G network, a unicom 4G network, and so on. If the electronic device is a multi-card electronic device and cannot realize that all card slots simultaneously support networks of 4G and above systems, optionally, all networks of the acquired network condition information originate from a target network provider, and the target network provider is a network provider to which an SIM card of the network supporting 4G and above systems on the electronic device belongs.
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, 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.
Alternatively, for the network condition information obtained 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 obtains the network condition information, and the closer the detection position is to the position when the electronic device obtains the network condition information, the higher the accuracy of the network condition information is.
In this embodiment, the information providing apparatus may be of various 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: and acquiring network condition information covering all networks of 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.
In one embodiment, the type of the information providing apparatus is a terminal, and the acquiring, according to the type of the information providing apparatus, network status information of all networks covering the electronic apparatus from the information providing apparatus by using an acquiring method corresponding to the information providing apparatus includes: the method comprises the steps of obtaining network condition information of all networks covering the electronic device 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 obtained 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 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 is the same as the network status of the network covering the terminal, and optionally, when the electronic device and the terminal use the network of the same operator, 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 which is 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 terminals within a preset distance range, for example, a mobile and a connected SIM card is installed on the electronic device at the same time, 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, acquiring the network status information of all networks covering the terminals, which is stored by the terminals, includes: the method comprises the steps of obtaining network condition information of all networks covering a terminal, which is stored by the terminal closest to an electronic device. 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 type of the information providing apparatus is a server, and the acquiring, according to the type of the information providing apparatus, network status information of all networks covering the electronic apparatus from the information providing apparatus by using an acquisition method corresponding to the information providing apparatus includes: the electronic device sends the position of the electronic device to a server and receives network condition information of all networks covering the position, wherein the network condition information is acquired by the server, and 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 an operator server, or a server provided by another company. It can be understood that, when the server is an operator server, the electronic device sends its location to the server as: the electronic device sends the position of the electronic device to operator servers corresponding to the networks covering the electronic device. The electronic device receiving the network condition information of all networks covering the position of the electronic device, acquired by the server, comprises: the electronic device receives network condition information transmitted by each operator server, the network condition information being network condition information of a network covering a location of the electronic device among networks provided by each operator server. 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 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, for example, a mobile 4G network, appropriate network status information may be selected so that the detected location is closest to the location 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 location.
In this embodiment, if the behavior of acquiring the network status information of each network in all networks covering the electronic apparatus from the information providing apparatus fails, the electronic apparatus needs to detect the network status information of each network in all networks covering the electronic apparatus itself, and upload the network status information of all networks and the position of the electronic apparatus during the 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 the IP multimedia subsystem service described in this embodiment include, but are not limited to, 4G and 5G networks. The electronic device may determine whether it is currently under a network supporting the IP multimedia subsystem service by searching the network, for example, if the electronic device searches for a 4G network signal, it is under the 4G network.
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.
And 103, adjusting the difficulty of registering the IP multimedia subsystem by the electronic device based on the network condition information of all the networks.
It is understood that, if the electronic device is currently under the network supporting the IP multimedia subsystem (e.g. 4G or 5G), the electronic device will generally access the network with the best signal (generally, the network with the higher standard) in the network supporting the IP multimedia subsystem.
Optionally, when the difficulty of registering the IP multimedia subsystem by the electronic device is adjusted based on the network condition information of all networks, the network quality of all networks may be analyzed based on the network condition information of all networks 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.
Optionally, the network condition information in this example includes, but is not limited to, signal quality and signal strength, and the quality of each network may be measured by the signal strength and signal quality of the network.
In this embodiment, a network that supports the IP multimedia subsystem in the network that covers the electronic device is classified into a first type of network, and a network that does not support the IP multimedia subsystem is 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 is reduced, and if the network quality of the latter (network B) is better, the difficulty of registering the IP multimedia subsystem by the electronic device is improved. Optionally, the higher the network quality of the network a is than that of the network B, the greater 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, the greater the improvement amplitude of the difficulty of registering the IMS system by the electronic device is,
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 each network in all networks based on the network condition information of all networks covering the electronic device, and adjusting the difficulty of registering the IP multimedia subsystem by 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 the networks based on the network condition information of all the networks, 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 in the second type of network.
In many cases, the handover between the IMS and the circuit domain is to satisfy the call quality, so in an example, the quality of the IP multimedia subsystem service may be specified as the call quality, that is, the quality of the IP multimedia subsystem service under the network supporting the IP multimedia subsystem service in all networks may be analyzed based on the network status information of all networks covering the electronic device, and actually, the quality of the call in the IMS service under the network supporting the IP multimedia subsystem service in all networks may be analyzed based on the network status information of all networks covering the electronic device, and the call quality of other networks covering the electronic device. Therefore, the problem of call quality caused by the change of network quality can be avoided to a certain extent.
Further, corresponding network quality evaluation conditions may be set for the first type network and the second type network defined above, and the network quality evaluation conditions include a signal strength threshold and a signal quality threshold for evaluating the signal strength and the signal quality of the network, respectively. Optionally, the network quality evaluation condition of the first type of network is used to evaluate the quality of the service of the IP multimedia subsystem in the network, and different policies for adjusting the IMS registration difficulty are set for different qualities in the network quality evaluation condition of the first type of network; the quality evaluation conditions of the second type of network are used for evaluating the corresponding network quality (especially the call quality), and different IMS registration difficulty adjustment strategies are set for different network qualities in the network quality evaluation conditions of the second type of 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 condition information of all networks, and adjusting the difficulty of registering the IP multimedia subsystem by the electronic device according to the analysis result includes:
acquiring a preset corresponding relation between a geographical position and a network quality evaluation condition of each network, and the current geographical position of the electronic device;
acquiring network quality evaluation conditions corresponding to all the networks based on the preset corresponding relation and the current geographic position;
and analyzing the quality of the IP multimedia subsystem service under the network supporting the IP multimedia subsystem service in all the networks based on the network quality evaluation condition and the network condition information of all the networks, and adjusting the difficulty of registering the IP multimedia subsystem by the electronic device according to the analysis result.
The network quality evaluation condition corresponding to each network in all the networks may be read locally by the electronic device, or may be obtained from a server by the electronic device.
Optionally, in this embodiment, different network quality evaluation conditions may be set according to different geographic locations, and the geographic locations may be divided according to provinces, cities, districts, streets, and the like, or may be divided according to altitude ranges, building density, base station density, and the like, which is not limited in this embodiment. For example, for a 4G network, a metropolis and a south-charging city are divided into different geographic positions, different network quality evaluation conditions are set for the metropolis and the south-charging cities, a metropolis area and a suburb area are divided into different geographic positions, and different network quality evaluation conditions are set for the metropolis area and the suburb area.
Optionally, the obtaining, based on the preset correspondence and the current geographic location, the network quality assessment conditions corresponding to all the networks includes: and acquiring a signal intensity threshold and a signal quality threshold corresponding to a network supporting the IP multimedia subsystem service in all the networks and acquiring a signal intensity threshold corresponding to a network not supporting the IP multimedia subsystem service in all the networks based on the preset corresponding relation and the current geographic position.
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 all networks that support the IMS service, 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 that do not support the IMS service; each different quality level may correspond to a different signal quality and a different signal strength; 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 condition of each network, the network quality grade of the evaluated network can be obtained.
For example, in this embodiment, the network quality assessment condition for Shenzhen city is set to the content shown in table 1:
Figure GDA0003567205800000111
Figure GDA0003567205800000121
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, obtaining the network quality evaluation conditions corresponding to all the networks based on the preset corresponding relationship and the current geographic location includes: acquiring a signal intensity threshold and a signal quality threshold corresponding to a network supporting the IP multimedia subsystem service in all the networks and acquiring a signal intensity threshold corresponding to a network not supporting the IP multimedia subsystem service in all the networks based on the preset corresponding relation and the current geographic position;
analyzing the quality of the IP multimedia subsystem service under the network supporting the IP multimedia subsystem service in all the networks based on the network quality evaluation condition and the network condition information of all the networks, and adjusting the difficulty of registering the IP multimedia subsystem by the electronic device according to the analysis result comprises the following steps: if the signal strength of at least one network in the networks supporting the IP multimedia subsystem service is not lower than the corresponding signal strength threshold (the first signal strength threshold in the table 1), judging whether the network with the signal quality not lower than the corresponding signal quality threshold (the first signal quality threshold in the table 1) 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 strength of each network in the networks supporting the IP multimedia subsystem service is lower than the corresponding signal strength threshold, determining whether a high-quality network exists in the networks that do not support the IMS service in all the networks, if so, increasing the difficulty of registering the IP multimedia subsystem by the electronic device, and if not, decreasing the difficulty of registering the IP multimedia subsystem by the electronic device, wherein the high-quality network is a network whose signal strength is not lower than the corresponding signal strength threshold (the second signal strength threshold in table 1).
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.
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; alternatively, the operator server may modify the difficulty of registering the IMS with the electronic device according to an instruction of the electronic device through communication between the electronic device and the operator server, which is not limited in the embodiment.
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 from the information providing device multiple times every day, which is beneficial for the electronic device to better know 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. It is advantageous to acquire the network status information from the information providing apparatus a plurality of times to help the electronic apparatus cope with the problem caused by the network change.
In this embodiment, the network status information may be acquired by setting a time interval. Optionally, the obtaining of the network status information of each network in all networks covering the electronic device from the information providing device includes: and according to a preset acquisition time determining rule, acquiring network condition information of each network in all networks covering the electronic device from the information providing 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 the network condition information of each 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 each network in all networks covering the electronic device from the information providing device when the acquisition time arrives includes: and determining the current acquisition time according to a preset time interval and the previous acquisition time, and acquiring the network condition information of each network in all networks covering the electronic device from the information providing 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 each network in 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 time of acquiring the network condition information of each of all the networks covering the electronic device from the information providing device may be performed after the power-on, and a time duration between each subsequent time of acquiring the network condition information from the information providing device and a last time of acquiring the network condition information may be 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 condition information of each network in all networks covering the electronic device from the information providing 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 when the network condition information of each network in all networks covering the electronic device is acquired from the information providing device at the latest time, and acquiring the network condition information of each network in all networks covering the electronic device from the information providing 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 each network in all the networks covering the electronic device from the information providing device. Optionally, determining a rule according to a preset obtaining time, and obtaining network condition information of each network in all networks covering the electronic device from the information providing device when the obtaining time is reached includes: and if the current time is the preset acquisition time, acquiring the network condition information of each network in all the networks covering the electronic device from the information providing 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: and 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 acquired time, wherein the acquired position is the position of the electronic device when the information providing device acquires the network condition information of each network in all networks covering the electronic device. Optionally, determining a rule according to a preset obtaining time, and obtaining network condition information of each network in all networks covering the electronic device from the information providing device when the obtaining time is reached includes: 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, network condition information of each network in all networks covering the electronic device is acquired from the information providing 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 condition information of each network in all networks covering the electronic device from the information providing 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 each network in all networks covering the electronic device from the information providing 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 each network in 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 each network in all networks covering the electronic device from the information providing 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 network conditions in multiple systems are taken into consideration, and the situation that the registration condition of the IMS is disconnected from the network conditions of each network is avoided.
