Technical Field

Background

In the related art, when a roaming card searches for a Network, a Registered Public Land Mobile Network (RPLMN) is searched in advance, and if the Registered Public Land Mobile Network is not searched or the Network is searched due to reasons such as a virtual card information update and a Network switching abnormality, but the Network is found to be invalid, an Equivalent Home Public Land Mobile Network (EHPLMN) is continuously searched for communication via the EHPLMN.

However, when the virtual card searches for a network in a roaming situation, since the roaming area does not have an EHPLMN network, the existing network searching protocol provides that it is necessary to wait for the 4G/3G/2G network to search for a next network after the network searching sequence times out. Therefore, the user often needs to wait for a long time to search for the network, which reduces the use efficiency of the user.

According to the conventional Network searching principle, when a roaming card searches for a Network, a Registered Public Land Mobile Network (RPLMN) is searched in advance, and if the Registered Public Land Mobile Network is not searched or the Network is searched but found to be invalid due to reasons such as virtual card information update and Network exception, an Equivalent local Public Land Mobile Network (EHPLMN) is continuously searched, so that communication is performed through the EHPLMN. However, in the case of virtual card roaming, there is typically no EHPLMN network. If the EHPLMN Network is searched all the time, it is necessary to wait for all 5G/4G/3G/2G timeout before searching other roaming networks, such as User Controlled Public Land Mobile Network (UPLMN). In this case, the whole network search needs to wait for a long time, thereby affecting the user use efficiency.

As shown in fig. 1, an implementation flow diagram of a search configuration method for a roaming network is provided in an embodiment of the present application, an execution main body of the embodiment of the present application is a mobile terminal, and the mobile terminal provided in this embodiment may be implemented by any software and/or hardware, where the method includes:

step S110, acquiring an optional roaming network set, a forbidden networking list and network charge information in each optional roaming network of the virtual card to be started according to the operator identification and the application region information corresponding to the virtual card to be started;

step S120, the roaming networks contained in the forbidden networking list are removed from the selectable roaming network set;

step S130, network searching priority ranking is carried out on each roaming network in the selectable roaming network set according to the network charge information and the pre-acquired signal intensity information of each selectable roaming network, and a first network searching ranking list is obtained;

step S140, according to a pre-acquired historical network searching record corresponding to the virtual card to be started, performing network searching priority ranking on the first network searching ranking list to obtain a second network searching ranking list;

and step S150, configuring the roaming network searching sequence of the virtual card to be started according to the second network searching sequencing list.

Hereinafter, the above steps will be described in detail.

In step S110, according to the operator identifier and the application region information corresponding to the virtual card to be started, the set of selectable roaming networks of the virtual card to be started, the forbidden networking list, and the network charge information in each selectable roaming network are obtained.

It is understood that roaming, which is the name of a mobile telephone service, refers to a function that a mobile station leaves a service area registered by itself, and after moving to another service area, a mobile operator can provide services to the mobile station. Compared with an entity card, the virtual card does not have an actual physical carrier, an operator provides all card information of the virtual card, a terminal application stores all the information, and card loading is carried out through an APDU channel and a Modem so as to load information required by the Modem to the terminal, so that the purpose of starting the virtual card is achieved.

The virtual card to be activated generally supports multinational roaming, and is in a roaming state when the network to which the virtual card is connected is not a registered country operating network of the virtual card operator. For example, when a chinese user is at the boundary between yunan and burma, the virtual card used by the user's mobile terminal may be connected to the burma network, and at this time, the virtual card used by the user's mobile terminal is in a roaming state.

In the mobile terminal, one, two or more virtual cards to be started may be set, and may be preset in the mobile terminal when the mobile terminal leaves a factory, or may be stored in the mobile terminal by means of application information loading and the like. The virtual card to be started has a corresponding home service operator, and the service operator may have various identifiers for distinguishing different service operators. The identification includes but is not limited to: virtual card operator information, virtual card support network lists, virtual card types, etc.

In an embodiment of the present application, the operator identifier corresponding to the virtual card to be activated is an International Mobile Subscriber Identity (IMSI), and has 15 digits. The IMSI structure is as follows: mobile country code + mobile network code + mobile subscriber's identification number. Wherein, Mobile Country Code (MCC), the MCC resource is uniformly distributed and managed by International Telecommunications Union (ITU), 3 countries are uniquely identified to which the Mobile subscriber belongs, and china is 460. Mobile Network Code (MNC), MNC is 2 or 3 bits, china is 2 bits. Wherein, China Mobile uses 00,02,07, China Unicom uses 01,06, and China telecom uses 03,05, 11.

It should be noted that, in the same country, if there are multiple mobile network operators, the differentiation can be performed by the MNC. A Mobile Subscriber Identification Number (MSIN) is 9 bits or 10 bits.

The application region information refers to a charge region, such as denmark, to be applied by the virtual card to be started. Furthermore, in a country, the application area can be subdivided into a plurality of tariff zones according to the signal strength. For example, the iceland subdivides the application region into international 1-6 areas.

The Forbidden networking list comprises a roaming Network list which is acquired from an operator and is Forbidden to start a virtual card to be started to perform networking operation, such as a Forbidden access Public Land Mobile Network (FPLMN), and a Forbidden access list which is temporarily added to the virtual card in the roaming use process due to Network abnormity and the like.

The network charge information in each roaming network refers to roaming network price information of the virtual card to be started, which is obtained from an operator and used in each roaming network.

For example, when a citizen a in the united states is on business in China and a can obtain a virtual card, a virtual card forbidden access public land mobile network list configured corresponding to the virtual card is obtained from a server according to an operator identifier (such as an international mobile subscriber identity) and application location information (such as a mobile country code) corresponding to the virtual card to be started, so as to obtain a forbidden networking list of the virtual card to be started. In addition, network charge information (such as short message charge price, call charge price and flow charge price) of the virtual card in each roaming network can be obtained from a server according to an operator identifier (such as an international mobile subscriber identity) and application region information (such as a mobile country code) corresponding to the virtual card to be started.

Step S120, removing the roaming networks included in the forbidden networking list from the selectable roaming network set.

It is understood that the roaming network included in the forbidden networking list is a roaming network to which the virtual card cannot be connected or cannot be used even if the virtual card is connected in time. If the roaming network contained in the forbidden networking list is searched in the virtual card network searching process, the whole network searching time is prolonged. In view of this, it is necessary to eliminate the roaming networks included in the forbidden networking list from the set of alternative roaming networks.

It should be noted that the set of optional roaming networks is all roaming networks that the virtual card to be started can search for in a specific application area. Generally, when acquiring a virtual card, all optional roaming networks corresponding to the virtual card may be acquired from a server according to an operator identifier (such as an international mobile subscriber identity) and application location domain information (such as a mobile country code) corresponding to the virtual card to be started. For example, when the specific application region is sweden, 4 alternative roaming networks can be theoretically acquired from the server: tele2, Telenor, TeliaSera Mobile networks AB, and 3G. The set of 4 alternative roaming networks may form an alternative roaming network set.

In step S130, network search priority ranking is performed on each roaming network in the selectable roaming network set according to the network tariff information and pre-acquired signal strength information of each selectable roaming network, so as to obtain a first network search ranking list.

As shown in fig. 2, in an embodiment of the present application, step S130 specifically includes:

step S210, according to the network charge information, determining the network charge level of each roaming network in the selectable roaming network set.

It can be understood that the network charge information includes the network charge amount of each roaming network, and when the user acquires the virtual card, the network charge information of each optional roaming network may be acquired from the server according to the operator identifier (such as an international mobile subscriber identity) and the application location domain information (such as a mobile country code) corresponding to the virtual card to be started. Generally, the network tariff can be classified into three levels, namely, expensive, moderate and cheap, of course, four or more levels, which is not particularly limited in the embodiment of the present application.

It will be appreciated that when the network tariff amount of the alternative roaming network is too high, such as 100 yuan/20M for roaming traffic, the subscriber may choose to forego connecting to the roaming network. Therefore, the higher the tariff amount level of the optional roaming network, the lower the network searching priority should be generally given to the optional roaming network. Or the smaller the charge amount of the optional roaming network is, the higher the network searching priority should be generally given to the optional roaming network.

In an embodiment of the present application, an optional roaming network may include a plurality of services (e.g., short message service, call service, and traffic service), so that the network charge amount of each amateur may be obtained separately. Therefore, the network charge level of each service can be determined firstly, and then the network charge level of the whole selectable network can be determined. For example, when the roaming network set includes 4 roaming networks A, B, C, D, specifically, roaming network a includes sms service and call service; the roaming network B comprises a call service and a flow service; the roaming network C comprises a short message service and a flow service; the roaming network D includes a short message service, a call service, and a traffic service. Accordingly, the network tariff amount of each roaming network can be extracted from the network tariff information. For example, in the roaming network a, the short message service is 0.5 yuan/piece, and the call service is 2 yuan/minute; in the roaming network B, the conversation service is 2.4 yuan/minute, and the flow service is 10 yuan/200M; in the roaming network C, the short message service is 0.3 yuan/piece, and the flow service is 15 yuan/400M; in the roaming network D, the short message service is 0.6 yuan/piece, the call service is 1.8 yuan/minute, and the traffic service is 20 yuan/300M. Therefore, the network searching priority of each service included in the roaming network A, B, C, D may be determined first, and then the overall network searching priority of the roaming network A, B, C, D may be determined according to a certain rule. For example, different weightings may be given to each amateur to sum the weighted network searching priorities of the roaming networks. Of course, other methods may be used, and the present application is not limited thereto.

Step S220, determining a signal strength level of each roaming network in the selectable roaming network set according to the signal strength value of each selectable roaming network obtained in advance.

It can be understood that the signal strength may be reported to the server through the network searching result of the terminal when the device is started; or after the user acquires the virtual card, the user can obtain the signal intensity information of the current location by using the virtual card terminal and report the signal intensity information to the server. Therefore, the server can continuously obtain the signal strength information history records obtained by using the virtual cards of different operators in a certain region or a certain place by different terminals. Generally, the signal strength can be classified into three levels, i.e., strong, medium, and weak, and certainly can be classified into four or more levels, which is not particularly limited in the embodiments of the present application.

It can be understood that, when the signal strength signal of the selectable roaming network is too weak, for example, when the mobile phone has only a weak signal, the communication noise of the mobile terminal is large, a lot of retransmission phenomena are easily generated, and the use effect is poor. Thus, the lower the signal strength level of an alternative roaming network, the lower the network searching priority should generally be given to that alternative roaming network. Or the smaller the signal strength value of the alternative roaming network, the lower the network searching priority should be generally given to the alternative roaming network.

It is to be understood that the signal strength value of each roaming network may refer to an average signal strength value of each roaming network in a specific time period. It should be noted that, the method for obtaining the average strength of the network signal includes, but is not limited to, an arithmetic mean method, a geometric mean method, a weighted average method, and the like, and this is not particularly limited in the embodiment of the present application.

Step S230, determining a search priority corresponding to each roaming network in the selectable roaming network set according to a predetermined correspondence table of network tariff levels, signal strength levels, and search priorities.

In an embodiment of the present application, the search priority of each roaming network may be quickly obtained by establishing a predetermined correspondence table of network charge amounts, signal strength values, and search priorities. For example:

in the embodiment of the application, the network charge can be divided into 3 grades according to the amount of the network charge: high, medium, low. For example, the network tariff level of the optional roaming network with a call service below 2 m/min may be set high, the network tariff level of the optional roaming network with a call service greater than or equal to 2 m/min but less than 3 m/min may be set medium, and the network tariff level of the optional roaming network with a call service greater than or equal to 3 m/min may be set low. For another example, the network charge level of the optional roaming network with the short message service less than 0.3 yuan/piece may be set to be high, the network charge level of the optional roaming network with the short message service greater than or equal to 0.3 yuan/piece but greater than or equal to 0.5 yuan/piece may be set to be medium, and the network charge level of the optional roaming network with the short message service greater than or equal to 0.5 yuan/piece may be set to be low.

In the embodiment of the present application, the signal strength can be divided into 3 levels according to the magnitude of the signal strength value: strong, medium, weak. For example, the signal strength value of the alternative roaming network with an average network signal strength less than-90 dbm may be set to be weak, the signal strength value of the alternative roaming network with an average network signal strength of [ -90dbm, -70dbm) may be set to be medium, and the signal strength value of the alternative roaming network with an average network signal strength greater than or equal to-70 dbm may be set to be strong.

As shown in table 1, in an embodiment of the present application, the set of selectable roaming networks includes 9 selectable roaming networks A, B, C, D, E, F, G, H, I, so that the network tariff level and the signal strength level of each roaming network can be obtained by converting the network tariff level and the signal strength level of each roaming network according to the pre-obtained network tariff amount and signal strength value of each selectable roaming network and the above-mentioned signal strength level and network tariff level determination criteria, and further, a correspondence table of the network tariff level, the signal strength level and the search priority of the roaming network is established. Specifically, in the embodiment of the present application, the network tariff level of the roaming network may be divided into 3 levels: high, medium, low; the signal strength level of a roaming network can be divided into 3 levels: strong, medium, weak; the search priority of the roaming network can be divided into 5 levels: 5. 4, 3, 2, 1, wherein the larger the number, the higher the search priority.

TABLE 1 presentation example of the corresponding relationship between network tariff level, signal strength level and search priority

This has the advantage that it facilitates the virtual card to be activated to quickly determine the initial search priority of each roaming network in each tariff area.

It should be noted that the above-mentioned establishment method for establishing the correspondence table, network tariff level, signal strength level, search prioritization criteria, and the like are merely exemplary, and for example, the signal strength value may be represented by other parameters such as roaming network transmission peak value, roaming network delay time, and the like. In addition, in the embodiment of the present application, the machine learning model may be further used to train the obtained batch data samples to obtain a correspondence table of the network amount, the signal strength value and the search priority or a correspondence table of the network tariff level, the signal strength level and the search priority, which is not particularly limited in this embodiment of the present application.

Step S240, according to the search priority, performing network search priority ranking on each roaming network in the selectable roaming network set to obtain the first network search ranking list.

In an embodiment of the application, network search priority ranking may be performed on each roaming network in the selectable roaming network set according to a search priority of each roaming network, so as to obtain the first network search ranking list.

Taking a table data as an example for illustration, the first network search listing may include: and a fifth grade: a roaming network A; fourth level: roaming network B, roaming network C; third level: roaming network D, roaming network E, roaming network F; a second stage: roaming network G, roaming network H; a first grade: a roaming network I, wherein the network searching priority relation is as follows: fifth level > fourth level > third level > second level > first level.

In step S140, according to a pre-obtained historical network search record corresponding to the virtual card to be started, network search priority ranking is performed on the first network search ranking list to obtain a second network search ranking list.

In an embodiment of the present application, before step S140, the method further includes:

It is understood that the virtual card to be started may obtain the historical network searching record from the storage database and/or the server, where the historical network searching record is information about the networking situation, the network searching waiting time, the terminal location, and the like of the virtual card to be started, which is collected by the storage database and/or the server in real time. For example, the data may be reported to the server in real time by the Modem, or the terminal stores all the collected necessary information in the storage database of the virtual card, and reports all the abnormal information increments to the server in a performance dotting manner after the terminal network is available.

As shown in fig. 3, in an embodiment of the present application, step S140 specifically includes:

step S310, determining historical abnormal types and the total times of occurrence of the historical abnormal types corresponding to all roaming networks in the first network searching sequencing list according to the historical network searching records corresponding to the virtual card to be started.

It can be understood that the types of the historical abnormal types corresponding to the abnormal occurrence of each roaming network in a predetermined time may be determined and the total occurrence frequency of each historical abnormal type may be counted according to the requirements of the accuracy of network searching, the frequency of occurrence of the historical abnormal types, whether the virtual card needs to be restarted after the historical abnormal types occur, and the like, which is not particularly limited in the present application.

Step S320, adjusting the network searching priority of each roaming network according to the historical abnormal type and the total number of times of occurrence of the historical abnormal type corresponding to each roaming network in the first network searching sorting list, so as to obtain the second network searching sorting list.

In an embodiment of the present application, step S320 specifically includes:

firstly, when the historical abnormal type of the specific roaming network in the first network searching sequencing list is a first preset abnormal type and the total times of the historical abnormal types are greater than or equal to a first preset abnormal threshold, the network searching priority of the specific roaming network is adjusted to be a first level.

In one embodiment of the application, the historical exception types may include two types, a recoverable exception type and an unrecoverable exception type. The recoverable exception type is a type capable of recovering the exception without restarting the virtual card, namely a first preset exception type. The unrecoverable exception type is a type in which the virtual card needs to be restarted to repair the exception, that is, a second predetermined exception type. The first abnormal threshold frequency may be set reasonably according to requirements such as the occurrence frequency of the unrecoverable abnormal type, the abnormal duration and the like, and this is not particularly limited in the embodiment of the present application. For example, 1 time. The second abnormal threshold frequency may also be set reasonably according to requirements such as occurrence frequency of recoverable abnormal types, abnormal duration time, and the like, which is not particularly limited in the embodiments of the present application. For example, 3 times.

In one embodiment of the present application, the searching priority may be divided into five levels, a first level, a second level, a third level, a fourth level, and a fifth level. Wherein the priority level relationship of each level is: first level < second level < third level < fourth level < fifth level. Of course, the division of the levels in the embodiments of the present application is only exemplary, and the division may be two-level, three-level, four-level, or other levels. For example, when the predetermined search priorities of the roaming network a, the roaming network B, the roaming network C, the roaming network D, and the roaming network E are: roaming network a > roaming network B > roaming network C > roaming network D > E. Wherein, the unrecoverable exception of the roaming network A occurs for 3 times; the recoverable exception of the roaming network C is 2 times; the unrecoverable exception of the roaming network B is 1 time; the recoverable abnormality of the roaming network D is 1 time; the roaming network E is abnormal 0 times.

Because the number of times that the roaming network A can not recover the abnormity is larger than the number of times of the first abnormity threshold value by 1 time, the network searching priority of the roaming network A is directly adjusted to the first level.

Secondly, when the historical abnormal type of the specific roaming network in the first network searching sorting list is a first preset abnormal type and the total times of the historical abnormal types are less than the first abnormal threshold times,

still in the above example, if the number of times of occurrence of the unrecoverable abnormality in the roaming network B is 1 and is less than or equal to the first abnormality threshold number of times 1, the network searching priority of the roaming network B is adjusted to the second level.

Then, when the historical abnormal type of the specific roaming network in the first network searching sorting list is a second preset abnormal type and the total times of the historical abnormal types are larger than or equal to a second abnormal threshold time, the network searching priority of the specific roaming network is adjusted to be a second level.

Still as described in the above example, since the roaming network C has 3 recoverable exception types, which is equal to the second exception threshold times 3 times, the network searching priority of the roaming network C may be adjusted to the second level.

And finally, when the historical abnormal type of the specific roaming network in the first network searching sequencing list is a second preset abnormal type and the total times of the historical abnormal types are less than the times of a second abnormal threshold or the specific roaming network is not abnormal, adjusting the network searching priority of the specific roaming network to be a third level, wherein the network searching priority of the third level is higher than that of the second level.

Still in the above example, since the roaming network D has 1 recoverable anomaly type, which is less than the second anomaly threshold for 3 times, and the roaming network E has an anomaly of 0 time, at this time, the roaming network D and the roaming network E may be adjusted to the third level.

In another embodiment of the present application, when the historical exception type of the specific roaming network in the first network search listing is the first predetermined exception type and the total number of times of occurrence of the historical exception type is less than the first exception threshold number of times, it is continuously determined that the historical exception type of the specific roaming network in the first network search listing is the second predetermined exception type and the relationship between the total number of times of occurrence of the historical exception type and the second exception threshold number of times. Specifically, when the total number of times of occurrence of the first predetermined abnormal type of the specific roaming network in the first network searching sorting list is less than the first abnormal threshold number of times and the total number of times of occurrence of the second predetermined abnormal type is greater than or equal to the second abnormal threshold number of times, the network searching priority of the specific roaming network is adjusted to the second level. When the total occurrence frequency of the first preset abnormal type of the specific roaming network in the first network searching sequencing list is smaller than the first abnormal threshold frequency and the total occurrence frequency of the second preset abnormal type is smaller than the second abnormal threshold frequency, the network searching priority of the specific roaming network is not adjusted.

The method has the advantages that the first network searching record can be adjusted in a targeted mode according to the historical network searching record, a more reasonable second network searching sequencing list is obtained, and therefore network searching waiting time is reduced to the maximum extent.

Of course, other equivalent or similar network searching priority readjusting methods may also be adopted in the embodiment of the present application, so that the second network searching ranking list is obtained on the basis of the first network searching ranking list, which is not particularly limited in the embodiment of the present application.

It can be understood that, after the second network search sorting list is obtained, the second network search sorting list may be configured in the virtual card to be started, so that after the virtual card to be started is started, roaming network search is performed according to the second network search sorting list.

As shown in fig. 4, in an embodiment of the present application, step S150 specifically includes:

step S410, selecting a roaming network with the first network searching priority from the second network searching sorting list, and configuring the roaming network with the first network searching priority as a first searching cis-position network.

It is understood that, since the Registered Public Land Mobile Network (RPLMN), which is the PLMN Registered by the terminal before the last power-off or Network disconnection, is temporarily stored in a Universal Subscriber Identity Module (USIM) card. In general, the RPLMN is a roaming network. Therefore, a roaming network with the first priority can be selected from the second network searching list, and the roaming network with the first priority can be configured as the first searching cis-position network, namely the registered public land mobile network.

For example, when the second search list is sorted, there are 10 roaming networks: in summary, a second network searching list can be obtained, and the network searching priorities of 10 roaming networks are: third level: roaming network C1; a second stage: roaming network B2, roaming network B3, roaming network C2; a first grade; roaming network A1, roaming network A2, roaming network B1, roaming network C3, roaming network D1 and roaming network D2, wherein the network searching priority relationship is as follows: third level > second level > first level. Thus, the roaming network C1 may be configured as a first search order network.

Step S420, configuring all roaming networks except the roaming network with the first search priority ranking in the second search ranking list as a second search priority network, where the second search priority network searches after the first search priority network.

It is understood that the User Controlled Public Land Mobile Network (UPLMN) is a plmn manually selected by the User at the terminal.

For example, when the second search listing: third level: roaming network C1; a second stage: roaming network B2, roaming network B3, roaming network C2; a first grade; roaming network A1, roaming network A2, roaming network B1, roaming network C3, roaming network D1 and roaming network D2, wherein the network searching priority relationship is as follows: third level > second level > first level. Accordingly, the roaming networks of the second level and the third level may be configured as the second search order network.

As shown in fig. 5, in an embodiment of the present application, after step S420, the method further includes:

step S510, obtaining an operator-controlled roaming network set corresponding to the virtual card to be started.

It is understood that Operator Controlled Public Land Mobile Network (OPLMN) refers to all Public Land Mobile networks that an Operator can control. Therefore, the operator corresponding to the virtual card to be started can obtain the roaming network set controlled by the operator.

Step S520, removing the roaming networks included in the second network searching sorting list from the roaming network set, so as to obtain an alternative roaming network set.

Step S530, configure the roaming networks included in the candidate roaming network set as a third searching order network, where the third searching order network searches after the second searching order network.

It will be appreciated that the number of roaming networks included in the operator-controlled set of roaming networks is generally greater than or equal to the number of roaming networks included in the second search listing. Therefore, the roaming networks included in the second network searching list can be removed from the roaming network set, and the roaming networks in the rest part of the operator-controlled roaming network set can be obtained. In this case, these remaining roaming networks may be grouped into a set of alternative roaming networks, and the roaming networks included in the set of alternative roaming networks may be set as a third search ranking network that searches after the second search ranking network.

In an embodiment of the present application, after step S150, the method further includes:

It can be understood that, in the process of performing network searching priority ranking on the first network searching ranking list according to the pre-acquired historical network searching record corresponding to the virtual card to be started, a verification mechanism needs to be set when the historical network searching record may have a deviation or a network searching record that does not conform to the actual situation. By comparing the relationship between the total roaming network search waiting time and the preset waiting threshold time, whether network search priority ranking of the first network search ranking list according to the pre-acquired historical network search record corresponding to the virtual card to be started is proper can be roughly determined.

It should be noted that the preset waiting threshold time can be determined according to a large number of tests, for example, 2 min. The embodiment of the present application is not particularly limited to this.

As shown in fig. 6, in an embodiment of the present application, after step S150, the method further includes:

step S610, network searching information of each roaming network in the network searching process is monitored.

It can be understood that, during the network searching process using the virtual card, the mobile terminal may monitor the network state of each roaming network in the network searching process in real time, including data such as the current connected network of each roaming network, the number, name, time of the searched networks, and the like.

Step S620, when the network state of the specific roaming network is of an abnormal type, sending the network state of the specific roaming network to the storage database and/or the server of the virtual card to be started, so that the storage database and/or the server of the virtual card to be started update the historical network searching record according to the network state of the specific roaming network.

It can be understood that, according to the network searching information of each roaming network, whether the network state of each roaming network is an abnormal type or not and an attributed abnormal type can be analyzed according to the method disclosed in the embodiment of the present application. Then, the network state of the specific roaming network may be sent to the storage database and/or the server of the virtual card to be started, so that the storage database and/or the server of the virtual card to be started update the historical network searching record according to the network state of the specific roaming network.

The advantage of this is to ensure that the virtual card can obtain the latest historical network searching record when being started each time.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
