Cross-reference to related applications

This application is based on a Chinese patent application with an application number of 201810949202.9 and an application date of August 20, 2018, and claims the priority of the Chinese patent application. The entire content of this Chinese patent application is incorporated herein by reference.

Technical field

The present application relates to the field of communication technology, but is not limited to the field of communication technology, and in particular, to a method, a device, a terminal, and a computer storage medium for network switching.

Background technique

Networks of different standards may have different network qualities in different places. For example, in a certain area, network A can work normally, but network B has poor network quality and often drops. However, in the neighboring areas, the opposite is true. Network B can be used normally, while network A has poor network quality. Unless the terminal is replaced with a card in each area, users can only choose network A or network B individually, and endure the difference in network quality caused by the same mobile network in different places.

With the development of technology, terminals with dual cards appear. Users do not need to uninstall the SIM card of the terminal, and users can manually switch networks according to the service of the dual card to reduce network quality problems caused by a single network in different regions. Now, ESIM (Embedded Subscriber Identification Module) technology has appeared. It has the advantage of one card and multiple numbers. By configuring a profile, the terminal manually selects according to the user or switches to the corresponding network according to the current roaming status.

However, the current network switching technology can use manual user-based switching, or use roaming-based selection. When the user manually selects the network switching, the switching efficiency is low. When performing network switching based on the roaming status, it only saves network costs. There is a high probability that the network to which you are switching will have poor network quality.

detailed description

To make the objectives, technical solutions, and advantages of the embodiments of the application clearer, the specific technical solutions will be described in further detail below with reference to the accompanying drawings in the embodiments of the application. The following examples are used to illustrate the disclosure of the application, but are not intended to limit the scope of the disclosure.

It should be noted here that the network switching mentioned in the embodiments of the present application refers to switching from the network of one operator to the network of another operator. In a specific embodiment of the present application, an ESIM terminal is used as an example.

ESIM is an embedded SIM that is built into the terminal and is not removable. When a user wants to use a carrier ’s network, the user signs a contract with the carrier and can download the corresponding ESIM profile file from the carrier. The terminal You can access the network through the activated profile file. As shown in Figure 1, an ESIM card can contain multiple different profiles. Among them, a profile file is equivalent to a virtual SIM card, and a profile file corresponds to an operator-specific number. Profile file parameters usually include MCC (Mobile Country Code), MNC (Mobile Network Code), EID (EUICC-ID), ICCID (Integrate Circuit Card Identity), IC card identification code), IMSI (International Mobile Subscriber Identity), PIN (Personal Identification Number), MDN (Mobile Directory Number, mobile phone number) and other data. It should be noted that when the network switching method is applied to other multi-number terminals, such as dual-card terminals or multi-card terminals, the main difference from the ESIM card is that, in theory, the function of a profile file corresponds to a physical SIM card, respectively. Functions.

An embodiment of the present application provides a network switching method. The network switching method may be applied to a terminal, and the terminal may be an Internet of Things device, a mobile terminal, a tablet computer, and a smart wearable device with communication functions. Referring to FIG. 2, the network switching method includes the following steps:

Step 201: Detect current location information of the terminal;

The current location information of the terminal refers to information related to the geographical position of the terminal, such as cell base station information and satellite navigation system positioning information, that is, GPS information. The position information may also include height measurement information. For example, in a shopping mall or other building, an indoor positioning system may be used to perform height measurement to determine the specific floor position in the building.

Step 202: Match the network switching rules with the current location information to determine the target network parameters that match the network quality that meets the set conditions. The network switching rules include the correspondence between location information and network parameters. The network parameters include Network quality parameters and network identification parameters determined by historical network quality data;

Among them, network quality parameters refer to related parameters used to characterize network signal quality. Network quality parameters are determined based on historical network quality data. Network quality data includes but is not limited to: signal strength, frequency of dropped networks, number of failures, type of failure, network Rate, etc. The network quality parameter determined based on the historical network quality data refers to a parameter determined according to the historical network quality data corresponding to the destination location, and determines the quality of the network quality of the destination location. The network identification parameter refers to a network identification used to characterize an operator's network identity, including a 3-digit MCC and a 2- to 3-digit MNC. For example, the network identification of China Mobile's GSM network is "46000", the network identification of China Unicom's GSM network is "46001", and the network identification of China Telecom's CDMA network is "46003". The network quality meeting the set conditions may mean that the network quality is relatively optimal, or that the network quality is better than a preset condition parameter. Here, the terminal sets a network switching rule including a network quality parameter and a network identification parameter determined based on historical network quality data, and matches the network switching rule according to the current location, so as to determine the optimal network quality corresponding to the current location that meets the set conditions. The internet. It should be noted that the current location information and the location information in the network switching rule are not required to be completely the same, and a certain range of errors is allowed.

Step 203: Find the corresponding profile according to the network identification parameter in the target network parameters, and switch the current network to the network corresponding to the profile.

Here, the target network parameter refers to a network with a relatively optimal network quality corresponding to the current location. When the current network connected to the terminal is inconsistent with the network corresponding to the target network parameter, it switches to the operator network corresponding to the target network parameter. To ensure that the terminal can automatically select the matching network with the best network quality according to the current location. Wherein, if the current location information is new location information, the terminal may also collect network quality data of the currently connected network. If the network quality does not reach a preset condition, then switch to another operator network and judge again that the network quality has not reached When the conditions are preset, switch to the next operator network again until the network quality of all the operator networks is compared, and an operator network with a relatively good network quality is selected.

For example, a terminal user likes to play on a fixed line in a certain area. The terminal has contracted with operator network A and operator network B. The terminal uses network A by default. When traveling for the first time, the user found that when driving the car to the first area, network A experienced a network failure, such as a worsened network signal, dropped network, etc., and then triggered the terminal's network data collection function, and the terminal switched the network to network B. The network works normally and collects the network data of network B. However, in the second area, network B has a network failure, such as a limited network speed. Similarly, the terminal can switch the network to network A, and the network works normally. In this way, the terminal collects the network quality data of the network A and the network B corresponding to the first area and the second area respectively, and obtains the correspondence between the location information of the first area and the second area and the network quality parameters of the network A and network B. Get the network switching rules. When the terminal user comes to the first area again, the terminal matches the network switching rule according to the location information of the first area, determines that the network quality of the network B in the first area is better, and the terminal automatically switches to the network B. In the same way, the terminal can collect network quality data corresponding to different historical location information in real time to enrich network switching rules. By setting this network switching rule, the terminal can automatically trigger the ESIM network switching process based on real-time location information, find the optimal network, and improve the network quality used by users.

In the network switching method provided in the embodiment of the present application, the current location information is matched with the network switching rule determined based on the historical network quality data to determine a destination network that meets the preset conditions, and find the corresponding profile of the terminal according to the destination network. The terminal network switches to the destination network corresponding to the profile, so that the terminal can predict the optimal network quality in advance based on the network switching rules formed by historical network quality data, and automatically switch to the optimal network at the current location , The network quality of the terminal at the current location can be improved without increasing hardware equipment, and the user experience can be improved.

In one embodiment, the network switching method further includes: detecting current time information of the terminal; step 202, matching the network switching rule with the current location information according to the current location information, and determining that the matched network quality meets the set conditions Target network parameters, the network switching rule includes a correspondence between location information and network parameters, and the network parameters include network quality parameters and network identification parameters determined based on historical network quality data, including:

Matching the current location information with a network switching rule to determine a target network parameter whose network quality meets a set condition within a time period corresponding to the current time information, the network switching rule including location information, time information, and network parameters Correspondence, the network parameters include network quality parameters and network identification parameters determined based on network quality data corresponding to historical time.

Among them, different time periods can be distinguished, network quality data of different time periods can be collected at the same location, and the terminal sets a network switching rule for determining a destination network parameter based on the network quality data corresponding to the historical time. The network switching rules are matched according to the current time and location, so that the network quality corresponding to the current time and location can be determined to meet the set optimal network.

For example, an ESIM terminal user likes to hang out in a shopping mall all day long. The ESIM terminal signs up with network A and network B. The terminal uses network A by default when it is turned on. The first time period is from 8 am to 10 am. On the 5th floor of the mall, the terminal network A is working normally. The second time period is from 10 am to 12 am. The traffic on the 5th floor of the mall is increasing, and the terminal network A appears. Faults such as limited network speed, collect network quality data of network A, while the terminal network is switched to network B, network B works normally, and collect network quality data of network B; 12 to 2 pm is the third time period, the mall The number of users using network B increased on the fifth floor. If network B fails, such as dropped calls, the network quality data of network B is collected. The terminal switches to network A, collects the network quality data of network A, and compares the quality data of network A and network B. Then select network A with better network quality. Here, the terminal can use the GPS system to determine that the user is in the mall, and can also use the WiFi system to determine that the user is on the 5th floor of the mall. In this way, the terminal collects network quality data of the network A and network B corresponding to the first time period, the second time period, and the third time period of the same location, and obtains the first time period, the second time period, and the third time period of the same location. Correspondence with quality parameters of network A and network B to obtain network switching rules. When the end user came to the 5th floor of the mall again at 9 am, the terminal matched the network switching rules with the location information according to the first time period, and determined that the network B network quality was better in the first time period at the location. The terminal automatically switches to network B.

In the above embodiment of the invention, the network quality parameters are differentiated according to time periods. For the network quality data corresponding to different time periods at the same location, determining the network with the best network quality at the same location in different time periods is equivalent to In locations with large differences in network quality in different time periods, such as shopping malls and hospitals with large human traffic, the conditions for network switching can be further refined, the accuracy of network switching can be improved, and the user experience can be improved.

In an embodiment, before the matching with the network switching rule according to the current location information, the method further includes: detecting network quality data corresponding to the current location information; and combining the current location information and the current time information. And the network quality data is stored in a network distribution database, and a network switching rule is created or updated based on the network distribution database.

Here, the network quality data refers to related parameters that characterize the network quality of the current terminal connected to the network. The network distribution database refers to a database of network parameters classified by location information and time information. The terminal storing the current location information, the current time information, and the network quality data in a network distribution database refers to searching for the location information corresponding to the current location information and the time information corresponding to the current time information in the network distribution database. Update network quality data to network quality data corresponding to location information and time information in a network distribution database, or add current location information, current time information, and network quality data to the network distribution database, and add the increased current location Information, current time information, and network quality are stored in association. Creating a network switching rule based on a network distribution database refers to creating a correspondence between time information, location information, and network parameters based on the newly added location information, time information, and network quality data of the network distribution database. Therefore, the network switching method provided in the embodiment of the present application can form a network distribution database by intelligently collecting historical network quality data and corresponding time information and location information, and can be obtained and updated in real time by intelligent learning analysis based on the network distribution database. A network switching rule reflecting the quality of the network corresponding to the current location and time, wherein updating the network switching rule refers to re-determining the time information, the network quality data corresponding to the updated time information and location information in the network distribution database, Network quality parameters corresponding to the location information.

For example, during a certain period of time in a newly built cell, the network operator network A and the network operator network B are covered. The user terminal is connected to network A by default when starting up. Due to the imperfect infrastructure of the operator's network A in this cell, network A has a network failure, while the operator's network B has the perfect infrastructure and the network B's network quality is better. The network quality data of the network A and the network B during the time period, and the correspondence relationship between the position and the network quality parameters of the network A and the network B during the time period is obtained, and the network switching rule is determined. When the user comes to this cell again in a certain period of time, the handover procedure is automatically triggered, and the terminal network switches to network B. However, in order to change the network quality of the community network A, the operator of network A adds infrastructure, and the network quality of network A is significantly improved, which is better than that of network B. When the user comes to the cell again in a certain period of time, the terminal collects the network quality data of network A, updates it to the network distribution database, and again obtains the corresponding relationship between the location and the network quality parameters of network A and network B during this time period, and determines the new Network switching rules. When the user comes to this cell again in a certain period of time, the handover procedure is automatically triggered, and the terminal network is still connected to the network A.

In the above-mentioned embodiment of the invention, the terminal collects network quality data of the current network, updates it to a network distribution database, and corrects the network switching rule through real-time updating of the network distribution database. The terminal can accurately calculate the network switching rule based on the modification Perform network switching or predict network quality changes in advance to further ensure the accuracy of network switching.

In one embodiment, storing the current location information, the current time information, and the network quality data in a network distribution database, and creating or updating a network switching rule based on the network distribution database includes: The location information, the current time information, and the network quality data are stored in a network distribution database on the server side, and the server is sent to create or update a network switching rule based on the network distribution database.

Here, the network distribution database where the current location information, the current time information, and the network quality data are stored in the server means that the network distribution database is located on the server, and multiple terminals upload the time information and location collected by the server to the server. The information and network quality data form a large network distribution database and are stored on the server; or a single terminal packages the network quality data of the current location collected by the terminal within the current time period and sends it to the server's network distribution database, and updates the corresponding network distribution database. content.

The server parsed the data packet and analyzed the content. Correspondingly, it is stored and classified into the network distribution database. The server establishes a network switching rule for the area at that time according to the network distribution database, and determines that the terminal located at the location at that time should be connected to the network B. The terminal supports the function of synchronizing server data and defaults to connect to network A. After entering the area during a certain period of time, the terminal synchronizes the server's network distribution database and network switching rules, automatically triggers the network switching process, and the network switches to network B.

The server acquisition mode means that after each terminal collects network distribution data, it uploads to the server and creates or updates a network distribution database in the server. If the terminal uses the local mode for network switching, the network distribution data collected by the terminal is used to determine the network switching rules and the network switching is performed; if the terminal uses the server mode, the network distribution data collected by the background server is used to determine the network. Switching rules for network switching. At the same time, it is also necessary to choose whether to receive updated network distribution data pushed by the server and whether to report the network distribution data collected by the terminal.

The network switching display module 305 is configured to select a network switching mode and prompt switching information.

Among them, the network switching mode can be set to automatic mode and manual mode. When the network switching decision and determination module 302 finds the target network, if the user selects the automatic mode, the network switching process is automatically triggered, and a message will be displayed on the network switching display module 305. If the user selects the manual mode, whether the network switching process is triggered every time needs to be performed according to the user selection, and the network switching display module 305 displays an option of whether to perform a network switching and a fault type.

In the above embodiment of the present application, the network switching setting module 304 is used to set the local mode and the server mode, so that the user can freely choose whether to upload network distribution data, which can better protect the data privacy of the user. The network switching display module 305 is used to display the prompt information to allow the user to freely judge whether to switch the network and improve the user experience.

In order to understand the network switching method provided by the embodiment of the present application, a terminal with an ESIM module is used to automatically switch the network. The use of the network distribution database uses the server mode and the automatic switching mode is used as an example. Please refer to FIG. The steps for switching include:

Step 701: Detect an instruction to activate a profile on the ESIM card, activate the profile, and access the corresponding network;

Step 702: Determine whether to synchronize the network distribution data of the profile. If the server mode is selected, if the terminal chooses to synchronize the network distribution database, the terminal receives the entry information of all the profiles on the ESIM card corresponding to the network distribution database;

Step 703: If the local mode is selected, the local network distribution database is enabled by default;

Step 704: Enter the network switching decision and decision service;

Step 705: Read the activated profile network distribution database and load it into the determination service process;

Step 706: Periodic detection and matching are performed in the determination service process. When it is determined that the current location of the user terminal matches the corresponding network distribution data rule, the terminal network switching function is triggered;

In step 707, the network rules are matched, and conditions such as network identification, location information, and time information may be used to match the network switching rules to find the destination network.

Here, in consideration of the working efficiency and performance issues of the terminal, the terminal may adopt periodic detection and matching of network switching rules, or may match network switching rules every time a new location is reached. The network switching rule is a decision database trained by a machine learning method according to a network distribution database, and is modified according to current network quality data. In addition to matching according to the location information, the matching may be based on the current network identifier and location information, or the location information and time information, or the current network identifier, location information, and time information. . The matching algorithm can be a matching rule algorithm or an intelligent learning algorithm.

Step 708: After finding the destination network, select a network switching mode and prompt for switching information.

Step 709: After the network switching mode is selected, search the corresponding profile in the terminal according to the destination network, deactivate the currently activated profile and activate the destination profile, and switch the current network to the network corresponding to the profile to be activated.

Step 710: Optimize the handover process. In order to improve the speed of searching the network, the terminal can preset a network search list of multiple profiles, and when searching the corresponding network according to the profile, match the network search list to speed up the process of searching the network;

In step 711, the handover process is completed, and it is prompted that the handover is complete. The terminal successfully switched to the destination network.

In the implementation of this application, the terminal obtains a network distribution database by selecting a local mode or a server mode, creates or updates a network switching rule based on the network distribution database, uses location information to match the network switching rule, determines the destination network, and intelligently determines the optimal network ; In order to speed up the network switching process, according to the preset network search list, the profile quickly matches the network.
