[0068] In the embodiment of the present application, the terminal device 110 is a device that supports switching between multiple user identification cards. Optionally, the user can manually select which user identification card to use to achieve the Internet access function; or, the user can also turn on the automatic switching Internet access card function of the terminal device 110, so that when a user identification card encounters a network lag, it automatically switches to another user identification card with better network communication quality for network communication. In some embodiments, the above-mentioned automatic switching Internet access card function can also be enabled by default, without the need for the user to manually enable it.

[0069] The User Identification Module (UIM) is an important component for storing user identity information and network authentication data in mobile communication devices. Among them, the above-mentioned user identification card may include but is not limited to: Subscriber Identity Module (SIM) card, Universal Subscriber Identity Module (USIM) card, Embedded SIM (eSIM) card, Universal Integrated Circuit Card (UICC card), Removable User Identity Module (R-UIM) card, etc., and may also include other types, which are not limited in the embodiments of the present application. Among them, the SIM card is the earliest user identification card, which is mainly used in 2G networks, such as the Global System for Mobile Communications (GSM), and provides basic encryption and authentication functions. The USIM card is a user identification card designed for 3G and 4G networks, which supports more complex encryption algorithms and two-way authentication, and provides higher security.

[0070] Exemplarily, the terminal device 110 includes a first user identification card 101 and a second user identification card 102. For example, the current Internet access card of the terminal device 110 is the first user identification card 101, and the terminal device 110 is within the coverage of the network device 120. After detecting a network freeze, the terminal device 110 can switch the current Internet access card from the first user identification card 101 to the second user identification card 102.

[0071] In related technologies, the terminal device can use AP scoring to detect the abnormality of the current network card in real time, trigger the network card switching and replace the network card. However, this solution requires continuous real-time perception and evaluation of the network score for about 10 seconds before triggering the network card switching action, which is slow.

[0072] In this regard, the subsequent embodiments of the present application provide a new network card switching solution, which can accurately switch the network card from one user identification card to another user identification card, ensuring the stability of the network connection and the optimization of the signal quality, and improving the user experience.

[0073] Please refer to Figure 2 , which shows a flow chart of a network card switching method provided by an exemplary embodiment of the present application. The method can be used in a terminal device, which includes at least a first user identification card and a second user identification card; wherein the terminal device can be a computer device that supports the network card switching function; for example, the terminal device can be the above-mentioned Figure 1 The terminal device 10 in the system shown; alternatively, the terminal device may also be Figure 1 Other terminal devices outside the system shown. The method may include step 210, step 220 and step 230.

[0074] Step 210: Acquire first cell information and second cell information; the first cell information is the cell information corresponding to the first user identification card, the second cell information is the cell information corresponding to the second user identification card, and the first user identification card is the current Internet access card of the terminal device.

[0075] The first user identification card and the second user identification card may belong to the same operator or different operators.

[0076] In an embodiment of the present application, the current Internet access card of the terminal device is the first user identification card, then the second user identification card and other user identification cards are alternative Internet access cards. When the current network quality is abnormal, the terminal device can switch the current Internet access card to the alternative Internet access card.

[0077] Among them, a cell is a basic unit of wireless communication, which refers to the area covered by a base station or a part of a base station (such as a sector antenna). The above-mentioned cell information may include information such as the cell identification, frequency, channel, etc. The above-mentioned first cell information may be the cell information related to the cell corresponding to the first user identification card when the terminal device is at the current location; the above-mentioned second cell information may be the cell information related to the cell corresponding to the second user identification card when the terminal device is at the current location.

[0078] Step 220: query the handover auxiliary information; the handover auxiliary information includes at least one set of cell information association relationships, and the cell information association relationship is used to indicate the handover from the Internet access card corresponding to the source cell information to the Internet access card corresponding to the target cell information.

[0079] The above-mentioned switching auxiliary information may be pre-set / configured in the terminal device.

[0080] Exemplarily, the above-mentioned handover auxiliary information may include a relationship diagram, a mapping diagram, an information base, a semantic network, etc. consisting of one or more groups of cell information association relationships.

[0081] Step 230: When a matching association relationship is found in the switching auxiliary information, the Internet access card of the terminal device is switched from the first user identification card to the second user identification card; the matching association relationship is a cell information association relationship with the first cell information as the source cell information and the second cell information as the target cell information.

[0082] If the source cell information in the switching auxiliary information is the same as the first cell information, and the target cell information corresponding to the source cell information is the same as the second cell information, the terminal device can switch the current Internet card to the second user identification card to improve the stability of the terminal device's network connection.

[0083] To sum up, through the scheme shown in the embodiment of the present application, according to the query results of the switching auxiliary information, the terminal device can automatically switch to another Internet card with better signal quality, thereby maintaining the stability of the network connection; compared with the related technology, this scheme does not need to be based on the status evaluation results of the current Internet card, but based on the switching auxiliary information pre-stored in the terminal device, it can quickly realize the intelligent switching of the Internet card between different user identification cards, thereby improving the accuracy and timeliness of the Internet card switching, and ensuring the stability of the network connection when the user uses the terminal device.

[0084] Based on the above Figure 2 In the solution shown, in a possible implementation manner, the switching auxiliary information is constructed by the cell information corresponding to the network card before switching and the cell information corresponding to the network card after switching during the historical switching process of the network card.

[0085] Optionally, the above-mentioned switching auxiliary information may include the cell information association relationship of the terminal device during the historical switching process; or, the above-mentioned switching auxiliary information may include the cell information association relationship of other terminal devices with the same current geographical location as the terminal device during the historical switching process; or, the above-mentioned switching auxiliary information may include the cell information association relationship of the terminal device during the historical switching process, and the cell information association relationship of other terminal devices with the same current geographical location as the terminal device during the historical switching process.

[0086] Exemplarily, if the above-mentioned switching auxiliary information includes the cell information association relationship of other terminal devices with the same current geographical location as the terminal device in the historical switching process, the operators corresponding to the user identification cards in other terminal devices with the same current geographical location as the terminal device should be the same as the operators corresponding to the user identification cards in the terminal device; at the same time, the operator corresponding to the current Internet access card of the terminal device should be the same as the operator corresponding to the Internet access card corresponding to the source cell information in the cell information association relationship.

[0087] Optionally, the above-mentioned historical switching process may include a process in which the user manually switches the network card; or, the above-mentioned historical switching process may include a process in which the terminal device automatically switches the network card according to specified conditions; or, the above-mentioned historical switching process may include a process in which the user manually switches the network card, and a process in which the terminal device automatically switches the network card according to specified conditions.

[0088] Exemplarily, in the process of constructing the above-mentioned handover auxiliary information, a specified condition for adding a new cell information association relationship can be set, and when the candidate cell information association relationship meets the specified condition, the cell information association relationship is added to the above-mentioned handover auxiliary information. For example, the above-mentioned specified condition can be that the number of handovers reaches a specified number, etc.

[0089] Through the scheme shown in the embodiment of the present application, the corresponding cell information before and after the terminal device switches during the historical switching process can be obtained in advance to construct the above-mentioned switching auxiliary information, which can improve the accuracy of the switching auxiliary information and further improve the accuracy of the network card switching.

[0090] Based on the solutions shown in the above embodiments, in a possible implementation, the handover auxiliary information includes a knowledge graph; the cell information association relationship is a triple in the knowledge graph; the triple includes a source node, a target node, and a handover relationship edge between the source node and the target node;

[0091] The source node contains source cell information; the target node contains target cell information; the switching relationship edge is used to indicate switching from the Internet access card corresponding to the source cell information to the Internet access card corresponding to the target cell information.

[0092] A knowledge graph is a semantic network composed of multiple pieces of knowledge through structuring technology, and each piece of knowledge is represented by a subject-predicate-object (SPO) triple; among them, the knowledge graph involved in the embodiment of the present application is a network that describes at least one group of cell information association relationships through SPO triples.

[0093] Please refer to Figure 3 , which shows a schematic diagram of a knowledge graph provided by an exemplary embodiment of the present application. Figure 3 Part (a) shows an example of the application of knowledge graph in the process of switching network cards. Figure 3 As shown in part (a) of the figure, taking the cell information association relationship 1 in the knowledge graph as an example, the cell information association relationship 1 includes a source node 10, a target node 20 and a switching relationship edge 30. The source node 10 corresponds to the source cell information 1, and the target node 20 corresponds to the target cell information 1. The switching relationship edge 30 indicates that in the historical switching process, there is a terminal device whose Internet access card is switched from the user identification card corresponding to the source cell information to the user identification card corresponding to the target cell information. The cell information association relationship can be used as a reference for the terminal device and other terminal devices.

[0094] The embodiment of the present application provides an implementable method for switching auxiliary information, which describes the association relationship of cell information related to the terminal device in the form of a knowledge graph, so that the relationship between the cell information before and after the network card is switched, and the direction of switching are clearer and more accurate, thereby improving the accuracy of constructing the switching auxiliary information.

[0095] Based on the solutions shown in the above embodiments, in a possible implementation, the above step 220 can be implemented as step 220a and step 220b.

[0096] Step 220a: Query the first triple in the knowledge graph, where the first triple is a triple whose source node contains the first cell information and whose target node contains the second cell information.

[0097] Exemplarily, the terminal device may first compare the first cell information with each source cell information in the knowledge graph to obtain a candidate triplet in which the source cell information is the same as the first cell information; then, compare the second cell information with the target cell information in the candidate triplet, and when the second cell information is the same as the target cell information in the candidate triplet, determine the candidate triplet as the above-mentioned first triplet.

[0098] Step 220b: When the first triplet is found, determine whether a matching association relationship is found in the handover auxiliary information.

[0099] Querying the first triple that meets the conditions in the knowledge graph is equivalent to successfully querying the above-mentioned matching association relationship; thereafter, the terminal device can switch the current Internet access card from the first user identification card to the second user identification card.

[0100] The embodiment of the present application provides a feasible solution for querying switching auxiliary information. By comparing whether the source node and the target node in each triple in the knowledge graph are the same as the first cell information and the second cell information, it is possible to quickly query whether there is a matching association relationship, thereby improving the accuracy and timeliness of network card switching.

[0101] Based on the solutions shown in the above embodiments, in a possible implementation, the knowledge graph further includes one or more location nodes, and the location nodes include geographic location information; the triples and the location nodes are connected through location relationship edges; the location relationship edges are used to indicate the geographic location of the cell corresponding to the cell information in the triples, and match the geographic location information in the location nodes;

[0102] The above step 220a may be implemented as follows:

[0103] Get the current geographic location information of the terminal device;

[0104] Query the first location node in the knowledge graph; the first location node is a location node that matches the current location information;

[0105] Among the triples connected to the first position node, the first triple is searched.

[0106] The address location information contained in the location node may be the geographical location of the cell corresponding to the cell information in the triplet. Exemplarily, the terminal device may obtain the geographical location information through positioning technology (such as satellite positioning technology).

[0107] There may be one or more triples connected to the same location node through location relationship edges. In other words, there may be one or more cell information associations corresponding to the same geographic location information.

[0108] in, Figure 3 Part (b) shows an example of the application of knowledge graph in the process of switching network cards. Figure 3 As shown in part (b) of FIG. 1 , the triple of cell information association relationship 1 corresponds to location node 40, and location node 40 includes geographic location information 1 of the cell corresponding to the cell information in the triple. Location node 40 is connected to source node 10 and target node 20 via location relationship edge 50. In addition, other triples such as cell information association relationship 2 are connected to the location node.

[0109] In an embodiment of the present application, a terminal device can obtain its own corresponding current geographic location information; thereafter, the current geographic location information can be compared with each location node in the knowledge graph to obtain a first location node that is the same as the first cell information; thereafter, in each triple connected to the first location node, it is queried whether the above-mentioned first triple exists; this scheme uses the current geographic location information of the terminal device as a pre-query condition, and can quickly query the first triple, thereby improving the accuracy and timeliness of the query matching association relationship.

[0110] In another possible implementation, the terminal device may also compare the first cell information, the second cell information and the current geographic location information with each triple in the knowledge graph and the address location information contained in its corresponding location node, and determine the triple in which the source cell information is the first cell information, the target cell information is the second cell information, and the address location information contained in the location node matches the current geographic location information as the first triple.

[0111] Please refer to Figure 4 , which shows a flow chart of a method for switching an Internet access card provided by an exemplary embodiment of the present application. Figure 4 As shown above Figure 2 The network card switching method shown also includes step 240 and step 250 .

[0112] Step 240: Obtain the historical switching record of the terminal device; the historical switching record includes the third cell information corresponding to the network card before switching and the fourth cell information corresponding to the network card after switching during a historical switching process of the network card of the terminal device.

[0113] The above historical switching record is the record information corresponding to the network card switching process executed when the terminal device detects an abnormality in the network access.

[0114] For example, the terminal device can score the network connection quality. When the network connection quality score is lower than a score threshold, it is determined that the Internet access is abnormal, and the network card can be switched at this time.

[0115] Among them, during each switching process of the Internet access card of the terminal device, the terminal device can record the cell information corresponding to the Internet access cards before and after the switching, and obtain a record set consisting of multiple switching records; thereafter, the terminal device can extract one or more switching records from the above record set as the historical switching information of the terminal device.

[0116] Exemplarily, the terminal device may set extraction conditions for extracting the historical switching information of the terminal device from the above record set. For example, the extraction condition may be that the number of times each switching record is recorded reaches a specified number; or for another example, the extraction condition may be that the geographic location information of each switching record meets a specified condition.

[0117] Step 250: Based on the historical switching records, construct a second triplet in the knowledge graph; the source node in the second triplet contains the third cell information, and the target node in the second triplet contains the fourth cell information.

[0118] Exemplarily, the terminal device may write the third cell information in the historical switching information into the source node in the newly added second triplet, and write the fourth cell information corresponding to the third cell information into the target node in the newly added second triplet.

[0119] Through the scheme shown in the above embodiments of the present application, the terminal device can construct triples in the knowledge graph based on the historical switching process of its own network card, so that the knowledge graph can match the movement route of the terminal device, thereby maximizing the accuracy and efficiency of triggering the network card switching through the knowledge graph.

[0120] Based on the solutions shown in the above embodiments, in a possible implementation, the historical switching record also includes historical geographical location information when the switching occurs;

[0121] The above network card switching method also includes:

[0122] Querying a second location node in the knowledge graph; the second location node is a location node that matches the historical location information;

[0123] When the second location node is found, the second triplet is connected to the second location node.

[0124] During each switching process of the network card of the terminal device, the terminal device can also record the historical geographic location information when the switching occurs; thereafter, the historical geographic location information can be compared with each location node in the knowledge graph to obtain a second location node that matches the historical geographic location information; thereafter, the second triple constructed above is connected to the second location node to improve the accuracy of constructing the knowledge graph.

[0125] Please refer to Figure 5 , which shows a schematic diagram of a knowledge graph provided by an exemplary embodiment of the present application. Figure 5 Part (a) shows an example of constructing a knowledge graph during the network card switching process. Figure 3 Based on part (b) of Figure 5As shown in part (a), the second triplet is the cell information association relationship 3, the source node in the second triplet contains the third cell information, the target node in the second triplet contains the fourth cell information, and the historical location information of the cell information association relationship 3 matches the geographic location information 1. Therefore, the second triplet is connected to the location node 40 of the geographic location information 1.

[0126] Based on the solutions shown in the above embodiments, in a possible implementation manner, the above network card switching method further includes:

[0127] If the second position node is not found, a second position node is created in the knowledge graph, and the second triple is connected to the second position node.

[0128] Among them, if the historical geographic location information is compared with the various location nodes in the knowledge graph, no location node matching the historical geographic location information is obtained; at this time, the terminal device can create a new second location node in the above knowledge graph; thereafter, the second triple constructed above is connected to the second location node, so as to improve the above knowledge graph and improve the accuracy and completeness of constructing the knowledge graph.

[0129] in, Figure 5 Part (b) of Figure 1 shows an example of how the knowledge graph is constructed during the network card switching process. Figure 3 Based on part (b) of Figure 5 As shown in part (b), the second triplet is cell information association relationship 3, the source node in the second triplet contains the third cell information, the target node in the second triplet contains the fourth cell information, and the historical location information of cell information association relationship 3 does not match the geographic location information 1; therefore, the terminal device creates a location node 60 in the knowledge graph, the location node 60 contains the geographic location information 2, and connects the second triplet with the location node 60 of the geographic location information 2.

[0130] Please refer to Figure 6 , which shows a flow chart of a method for switching an Internet access card provided by an exemplary embodiment of the present application. Figure 6 As shown above Figure 2 The network card switching method shown also includes step 260 and step 270 .

[0131] Step 260: After the network card of the terminal device is switched from the first user identification card to the second user identification card, the network connection quality of the terminal device is obtained.

[0132] The above network connection quality may include but is not limited to:

[0133] The round trip time (RTT) of the Transmission Control Protocol (TCP) refers to the time from when the sender sends data to when the sender receives the confirmation message from the receiver. By monitoring the RTT delay in TCP, you can preliminarily judge the performance of the network. Exemplarily, RTT can include the propagation time of the link, the processing time of the end system, and the cache and queue time of the network intermediate nodes such as routers. Among them, the propagation time of the link is the time required for the signal to propagate in the physical medium; the processing time of the end system is the time for the sender and the receiver to process the data; the cache and queue time of the network intermediate nodes such as routers is the cache and queue time of the data in the intermediate nodes such as routers.

[0134] Domain Name System (DNS) response time: refers to the time required from the DNS client sending a DNS query request to receiving a response from the DNS server. DNS response time directly affects the user's access speed and experience. A shorter DNS response time can significantly improve the web page loading speed and application response speed. Exemplarily, the DNS response time may include query time, transmission time, processing time, and response time. Among them, query time is the time it takes for the DNS client to send a query request; transmission time is the time it takes for the query request to be transmitted from the client to the DNS server; processing time is the time it takes for the DNS server to process the query request and generate a response; response time is the time it takes for the response to be transmitted from the DNS server back to the client.

[0135] User Datagram Protocol (UDP) quantity: refers to the number of data packets transmitted through the User Datagram Protocol within a certain period of time. UDP is a connectionless, unreliable transport layer protocol. The UDP quantity can reflect the activity of real-time applications in the network and the load of data transmission. By monitoring the UDP quantity, the real-time performance and load of the network can be evaluated.

[0136] In addition, the above-mentioned network connection quality may also include other information, which is not limited in the present application.

[0137] Step 270: Perform management operations on the matching association relationship according to the network connection quality.

[0138] In an embodiment of the present application, the terminal device can calculate various types of information contained in the current network connection quality according to a specified algorithm to obtain an indicator or value that can indicate the network connection quality, and perform management operations on the above-mentioned matching association relationship based on the indicator or value.

[0139] Exemplarily, the terminal device may compare the indicator or value with a pre-stored reference range, and the reference range is used to indicate that the network connection quality is good. If the above indicator or value does not meet the reference range, it means that the network connection quality at this time is not ideal, and the terminal device may delete the corresponding matching association from the switching auxiliary information; if the above indicator or value meets the reference range, the terminal device retains the corresponding matching association.

[0140] Among them, the above-mentioned specified algorithm can be pre-set / configured in the terminal device; for example, the weights corresponding to various types of information can be pre-set, and then the terminal device can perform weighted processing on various types of information included in the current network connection quality.

[0141] Through the scheme shown in the above-mentioned embodiment of the present application, according to the quality of the network connection after switching, the terminal device can timely update the above-mentioned switching auxiliary information so as to delete the expired matching association relationship in time, thereby dynamically optimizing the accuracy of the switching auxiliary information.

[0142] Based on the solutions shown in the above embodiments, in a possible implementation manner, the above step 250 can be implemented as follows:

[0143] When the network connection quality is lower than the network connection quality threshold, the matching association relationship is removed from the switching auxiliary information.

[0144] The network connection quality threshold may be pre-set / configured in the terminal device. If the network connection quality threshold is lower than the network connection quality threshold, it means that the current network connection quality is not ideal; if the network connection quality threshold is not lower than the network connection quality threshold, it means that the current network connection quality is good.

[0145] In an embodiment of the present application, if the network connection quality is lower than the above-mentioned network connection quality threshold, the terminal device can remove the matching association relationship corresponding to the last switch from the switching auxiliary information so as to continuously optimize the accuracy of the above-mentioned switching auxiliary information.

[0146] In a possible implementation, the situation where the network connection quality is lower than the network connection quality threshold may be temporary. Therefore, the removed matching association relationship can be added to the knowledge graph again through the above steps 240 and 250.

[0147] Based on the solutions shown in the above embodiments, in a possible implementation, the above step 270 can be implemented as follows: when the network connection quality is not lower than the network connection quality threshold, increase the score of the matching association relationship;

[0148] When the network connection quality is lower than the network connection quality threshold, the score of the matching association relationship is reduced;

[0149] When the score of the matching association relationship is lower than the score threshold, the matching association relationship is removed from the switching auxiliary information.

[0150] Exemplarily, the score of the above matching association relationship may be 3 at the initial time. If the network connection quality is not lower than the network connection quality threshold, the terminal device may add points based on the current score, for example, modify the score to 4; if the network connection quality is lower than the network connection quality threshold, the terminal device may subtract points from the current score, for example, modify the score to 2.

[0151] In addition, the score of the above matching association relationship corresponds to a score threshold; if it is lower than the score threshold, it means that the current network connection quality is poor. For example, the score threshold is 0. If the score of the above matching association relationship drops below the score threshold, the terminal device can remove the matching association relationship from the handover auxiliary information.

[0152] Optionally, the score of the matching relationship may have a corresponding upper limit. For example, the upper limit is 5. That is, the score of the matching relationship may be increased to 5 at most.

[0153] Optionally, the terminal device can obtain the score value of each increase or decrease in the matching association relationship based on the current network connection quality compared to the rate of change of the network connection quality before the network card is switched. For example, when the rate of change reaches a specified value (such as 60%), additional points can be added on the basis of the original increase in the score. For example, if the current network connection quality is 90, the network connection quality before the network card is switched is 50, and the rate of change is 80%, then the score of the matching association relationship can be increased from 3 to 4.5 or 5.

[0154] Through the scheme shown in the above-mentioned embodiments of the present application, the terminal device can modify the score of the matching association relationship according to the network connection quality, and then determine whether the matching association relationship should be removed according to the score of the matching association relationship; the accuracy of the switching auxiliary information can be further optimized to avoid the accidental deletion of certain matching association relationships.

[0155] Based on the solutions shown in the above embodiments, in a possible implementation manner, the cell information includes at least one of the following:

[0156] Cell frequency, physical cell identifier PCI, cell identifier ID.

[0157] The above-mentioned cell frequency point refers to a specific frequency point in the wireless frequency band used by the cell, which is used to determine the wireless signal coverage range of the cell and the use of frequency resources.

[0158] The above-mentioned physical cell identification (PCI) is a physical layer identification used to uniquely identify a cell, and is composed of a cell primary synchronization signal (PSS) and a secondary synchronization signal (SSS).

[0159] The cell ID is a unique identifier of a cell and is used to identify and manage different cells in a network.

[0160] The embodiments of the present application provide a variety of combinations of cell information. The above-mentioned cell information may include but is not limited to: cell frequency, PCI, cell ID or any combination thereof, and may also include other information, which is not limited in the embodiments of the present application, thereby improving the flexibility of obtaining the first cell information and the second cell information.

[0161] The solutions shown in the above embodiments can be applied to travel scenarios on fixed routes, for example, scenarios where users commute by means of transportation (such as high-speed rail, subway, bus, taxi, online car-hailing, private car). In this scenario, in addition to executing the action of switching to the network card, the card switching action and the card switching information are recorded synchronously. The card switching information includes the location information before and after the card switching, and the cellular cell information (i.e., the above-mentioned cell information). Afterwards, the multiple card switching information recorded in the early stage is used through machine learning to construct a knowledge graph as a priori information input and pre-stored in the terminal device.

[0162] When the user enters the line next time, the location information and cellular cell information will match the knowledge graph pre-stored in the terminal device, and the action of switching the network card will be executed in advance. In addition, after executing the action of switching the network card, it is necessary to verify the improvement results of the optimization execution to further update the knowledge graph pre-stored in the history.

[0163] For example, if the terminal device is a mobile phone, please refer to Figure 7 , which shows a schematic diagram of the establishment and application of a knowledge graph provided by an exemplary embodiment of the present application.

[0164] During the knowledge graph establishment stage, mobile phone manufacturers / service providers can pre-record the card switching information each time the mobile phone switches the network card. The card switching information includes the location information before and after the card switching and the cellular cell information before and after the card switching. Figure 7As shown in part (a) of FIG. 1 , when user 710 is carrying mobile phone 20 and is located at line 1, the network card of mobile phone 20 is switched from network card 201 to network card 202; at this time, mobile phone 20 automatically records the switching information of this network card switching action, including location information 1 before switching, cell information of cell 1 before switching, location information 2 after switching, and cell information of cell 2 after switching. Afterwards, the manufacturer / service provider of mobile phone 20 can establish or manage the knowledge graph 30 based on the switching information of this network card switching action, and upload the knowledge graph 30 to the server 40; accordingly, the server 40 can push the knowledge graph 30 to mobile phone 20 located at user 710.

[0165] In the application stage of knowledge graph, such as Figure 7 As shown in part (b), user 710 carries mobile phone 20 on line 1. Mobile phone 20 can obtain current location information and cell information, query the pre-stored knowledge graph 30, and determine whether the location information and cell information match the knowledge graph 30; if they match, mobile phone 20 can switch the Internet card of mobile phone 20 from Internet card 201 to Internet card 202 in advance.

[0166] Specifically, please refer to Figure 8 , which shows a flow chart of a knowledge graph application method provided by an exemplary embodiment of the present application. Figure 8 As shown, the above network card switching method includes the following steps:

[0167] S1: Get the current location of the terminal device;

[0168] S2: Determine whether the current location matches the location information in the historically stored knowledge graph;

[0169] If the current location matches the location information in the historically stored knowledge graph, proceed to step S3;

[0170] If the current location does not match the location information in the historically stored knowledge graph, return to step S1;

[0171] S3: Determine whether the current Internet access card matches the Internet access card of the source cell information in the historical pre-stored knowledge graph;

[0172] If the current Internet access card matches the Internet access card of the source cell information in the historical pre-stored knowledge graph, proceed to step S4;

[0173] If the current Internet access card does not match the Internet access card of the source cell information in the historical pre-stored knowledge graph, return to step S1;

[0174] S4: Switch the current Internet access card of the terminal device to the Internet access card corresponding to the target cell information;

[0175] S5: Update the historically stored knowledge graph.

[0176] On the one hand, based on the prior information provided by historical pre-storage, the terminal device can quickly and accurately switch the card. For individual users, especially those who commute on fixed routes, a personalized and precise optimization strategy is provided to improve the user's Internet access stability. On the other hand, because the mobile phone operation switching is driven by historical pre-storage prior information, rather than blind switching after real-time perception, it can give users a clearer prompt of the next behavior of the terminal device.
