Description

Roaming access method, information processing method, network access and information processing equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a roaming access method, an information processing method, a network access device, and an information processing device.

Background

With the development of intelligent terminals and the development of wireless network technologies, users expect to access networks at different locations using the same terminal. Since different locations may be covered by different communication networks, the end user may accordingly need to pay an expensive tariff for roaming services for information transfer, especially in case of international roaming.

In order to save the charges, on one hand, the mobile terminal user may need to purchase a subscriber identity card of the roaming place, i.e. a physical subscriber identity card, with which the user can access the communication network of the operator of the roaming place, but this causes much inconvenience to the user. If the user still uses the entity identification card of the user's regular residence to search the communication network of the roaming place and access, the cost is high and the network residence is slow. On the other hand, the user can apply for a virtual identification card, and the virtual identification card with lower cost at the roaming place is used for accessing the communication network at the roaming place.

Although the virtual id card can satisfy the requirement that the user roams freely with a low tariff around the world, since each mobile terminal manufacturer saves cost and simplifies development when the user starts the virtual id card function roaming, the mobile terminal needs to search the mobile network of the country of the roaming place in a full frequency band when accessing the communication network of the roaming place. Since a country has a plurality of different operators and most of the operators have a plurality of network systems such as 2G/3G/4G, etc., when the mobile terminal roams to a foreign place, it takes a long time for the mobile terminal to search for and access the communication network, thereby resulting in poor user experience.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application.

The mobile terminal in the embodiments of the present application includes various types of mobile communication devices, such as a mobile phone, a tablet computer, and a notebook computer, and may also be a portable, pocket, hand-held, computer-embedded, or vehicle-mounted mobile apparatus. The mobile terminal performs radio access networks under various communication networks to exchange voice and/or data. Typically, the communication network may be a global system for mobile communications (GSM) network, a Code Division Multiple Access (CDMA) network, a Wideband Code Division Multiple Access (WCDMA) network, a Long Term Evolution (LTE) communication network, or the like. Different types of communication networks may be operated by different operators. The type of the communication network does not limit the embodiments of the present application.

Fig. 1 schematically illustrates an application scenario of the technical solution of the embodiment of the present application. In fig. 1, the mobile terminal is a mobile phone as an example. Typically, the user of the handset is located at a regular premises, but may be transferred from resident to a roaming location due to work needs, travel, and the like.

And when the user is at the ordinary site, the user accesses the communication network by using the entity identification card of the ordinary site operator and carries out data or voice service communication. At present, if a mobile terminal is started at a regular place, a frequency point corresponding to a communication network needs to be searched based on an entity identity identification card, and then the mobile terminal resides in a cell of the communication network of an operator to which the entity identity identification card belongs through the frequency point. In the process of searching the frequency points of the communication network, when the mobile terminal supporting the entity identity identification card is powered off, the frequency points corresponding to the recently used communication network are stored in the entity identity identification card, and when the mobile terminal is powered on again, the frequency points corresponding to the communication network are read out from the entity identity identification card and are preferentially searched. If the most recently used network frequency point stored in the entity identity identification card cannot be searched, all frequency points corresponding to the communication network are searched.

However, when the user moves from the resident location to the roaming location due to work needs, traveling, and the like, if the user continues to use the entity identification card of the permanent location without replacing the entity identification card, the entity identification card belonging to the permanent location does not store the network residence record of the roaming location in the past. Therefore, in the process of searching the frequency point corresponding to the communication network in the roaming place, the user can only adopt the full frequency point to search the communication network available in the roaming place, and further, the network residence time is long, and the user experience is poor.

In addition, with the development of mobile network services and mobile terminals, some mobile terminals start to use the virtual identification card technology, and through the virtual identification card technology, the mobile terminal can apply for different virtual identification cards to the background according to the searched network information. Meanwhile, due to some reasons, the mobile terminal adopting the virtual identity card technology still needs to search all frequency points when searching the network-resident frequency points, so that the network searching speed is very low and the user experience is very poor.

The present method of searching for a communication network may comprise: step one, frequency sweeping: after the mobile terminal is started or reaches a roaming place, the mobile terminal immediately starts to scan a communication network and searches for a frequency point of the communication network; step two, frequency locking: after finding an available Frequency point, the mobile terminal locks the Frequency of the Frequency point through a Frequency correction signal on an FCCH (Frequency correction channel); step three, synchronization: after the mobile terminal locks the frequency point, the mobile terminal synchronizes with the 0 time slot of the frequency point through a Synchronization signal on an SCH (Synchronization Channel); step four, receiving system information: after the mobile terminal is synchronized with the 0 time slot of the frequency point, the system information of the cell where the frequency point is located can be obtained from the time slot. The content of the system information is many, in this step, the mobile terminal compares the system information with the information stored in the virtual identity identification card or the entity identity identification card to determine whether the frequency point is the frequency point of the communication network where the mobile terminal is located, if so, the resident frequency point is found, and the mobile terminal starts to access the frequency point corresponding to the communication network; if not, the mobile terminal abandons the frequency point and continues to use other frequency points to search the communication network.

Before the mobile terminal 101 searches the frequency point of the communication network, historical network residence information corresponding to a roaming place is obtained from the server 111; then the mobile terminal 101 determines the frequency points to be searched according to the historical network residence information, and does not need to search all the frequency points; and finally, sequentially carrying out network searching processing according to the acquired frequency points until the resident frequency points are found. Correspondingly, the problem that the speed of searching the communication network is very low due to the fact that all frequency points need to be searched in the process of searching the frequency points of the existing mobile terminal is effectively solved. The speed of searching for a communication network of the mobile terminal is increased.

In the embodiment of the present application, after the mobile terminal 101 arrives at the roaming location 141, the mobile terminal 101 may use the permanent physical identity card or the applied virtual identity card to search for a communication network that may reside at the roaming location 141. Only when the roaming location 141 searches for a communication network, the mobile terminal 101 held by the user first attempts to receive the historical network camping information of the past successful network camping of the roaming user (e.g., the mobile terminal 102) at the roaming location 141 from the server 111. If the server 111 stores historical presence information for a mobile terminal (e.g., mobile terminal 102, etc.), the server 111 feeds back the historical presence information to the mobile terminal 101. After that, the mobile terminal 101 performs network search based on the obtained historical network residence information, and when a suitable frequency point is searched, the mobile terminal 101 accesses a communication network according to the frequency point, wherein the access communication network, that is, the mobile terminal 101, and the base station 121 and the cell of the roaming operator establish uplink and downlink bidirectional connections.

In the embodiment of the present application, in a case that the server 111 does not store any historical network camping information, the mobile terminal 101 may search all available operator networks (i.e., communication networks) that can be searched in the current roaming area according to the current network search method, and register one by one until a correct operator network is searched, so that the mobile terminal may successfully access the communication network. Or when the mobile terminal 101 fails to search for a network according to the historical network residing information, the mobile terminal 101 may continue to search for a network by using the current network searching method, or may try to acquire the historical network residing information again after a certain period of time and access the communication network again according to the historical network residing information.

In the embodiment of the present application, if the mobile terminal 101 successfully accesses the communication network, the mobile terminal 101 further needs to send the information about successful network camping to the server 111. For example, the information related to successful web hosting may include: the system comprises an operator public land mobile network PLMN, a network-residing system (including 2G,3G or 4G and the like), a frequency band and network-residing cell information.

Therefore, the technical scheme of the access network at the roaming place can effectively improve the network residence experience of the user at the roaming place, and save the time for accessing the network for the user.

The following describes a roaming access method 200, an information processing method 500, a network access device 700, and an information processing device 800 according to an embodiment of the present application.

Fig. 2 schematically illustrates a flow chart of a roaming access method 200 according to an embodiment of the present application. The roaming access method 200 may be applied to the mobile terminal 101 shown in fig. 1.

As shown in fig. 2, the roaming access method 200 includes: determining that the mobile terminal arrives at a roaming place (S210); acquiring at least one set of historical network camping information corresponding to a roaming place, wherein the at least one set of historical network camping information is information used when other mobile terminals access a communication network of the roaming place (S220); and initiating access to the communication network of the roaming place based on the at least one set of historical camping information (S230). For example, the mobile terminal may be the mobile terminal 101 shown in fig. 1.

In S210, the location information of the roaming location may be compared with the current location information of the mobile terminal 101, and when the location information of the roaming location matches the current location information, it is known that the mobile terminal 101 has arrived at the roaming location. In one example, roaming location information may be pre-stored in the mobile terminal 101, and the current location information may be acquired by a positioning module of the mobile terminal 101 or obtained by receiving broadcast information of a base station of a new location when the mobile terminal 101 arrives at the new location. For example, the location information may be longitude and latitude information of a current location of the mobile terminal 101. In addition, when the current position information of the mobile terminal 102 needs to be acquired, the positioning module of the mobile terminal is restarted, and the current position information of the mobile terminal is acquired through a positioning device, wherein the positioning device can be a GPS positioning instrument, a beidou positioning device, a GPS beidou dual-mode positioning device and the like.

In S220, the step of obtaining at least one set of historical network camping information corresponding to the roaming destination may further include: the mobile terminal 101 transmits the location information of the roaming location of the mobile terminal 101 to the server 111, and thereafter the server 111 searches for the historical presence information corresponding to the location information based on the location information transmitted by the mobile terminal 101. For example, assuming that the server 111 is located at the roaming location a, when the mobile terminal 102 successfully camps on the network at the roaming location a, the mobile terminal 102 reports its network camping information to the server 111, and the server 111 stores the information as historical network camping information. In addition, since there are many users reporting the network-resident information to the server 111, the server 111 stores a large amount of historical network-resident information. As an example, the historical presence information may include: the PLMN of the operator who successfully resides in the network, the network residing system (including 2G,3G or 4G, etc.), the frequency band and the cell information of the network residing. The public land mobile network PLMN in turn comprises a mobile country code and a mobile network code.

In S230, access to the communication network of the roaming place is initiated based on at least one set of historical camping information. In one example, a set of historical camping information may correspond to information about one successful camping reported by one user. Specifically, the mobile terminal 101 performs network search according to the received historical network presence information, and obtains a network based on the search to perform access operation. A set of historical camping information may be used to record information about the network where a subscriber successfully camps on a network once roaming. For example, suppose that five users in roaming location a have completed successful network camping once, at this time, the five network camping users will send information related to the network that the users successfully camp on to the server 111, and finally, five sets of historical network camping information will be stored on the server 111 in roaming location a; when the mobile terminal 101 arrives at the roaming location a, the server 111 transmits at least one set of historical camping information it stores to the mobile terminal 101 upon request. Thereafter, the mobile terminal 101 searches for a network based on the received historical presence information and accesses the network. For another example, when the historical network camping information provided by the server 111 to the mobile terminal is the detailed information of the network camping cell, the mobile terminal 101 directly searches the frequency point information corresponding to the cell, and thus completes network camping quickly.

Fig. 3 schematically illustrates a flow chart of a procedure when the mobile terminal 101 accesses a network at roaming using a virtual identification card. The virtual identification card is obtained and loaded by step S310 in fig. 3, and it is determined whether the roaming access method shown in fig. 2 needs to be started by step S320, step 330 indicates when the roaming access method shown in fig. 2 is started, and step 340 indicates another conventional roaming access method.

In S310, a virtual identification card is obtained, and the virtual identification card is loaded in the mobile terminal.

In one embodiment of the present invention, acquiring the virtual identification card may include: downloading and pre-storing a virtual identification card of a roaming place from a server before arriving at the roaming place; or the virtual identification card of the roaming place is downloaded from the server 111 and stored after arriving at the roaming place. Wherein, the server before arriving at the roaming place can be the server which is usually placed at the user's station. For example, the type corresponding to the virtual identification card may include: a virtual Subscriber Identity Module (sim), a virtual Universal Subscriber Identity Module (USIM), a virtual Removable User Identity Module (RUIM), and a virtual Universal Subscriber Identity Module (UIM). The SIM card can be applied to a GSM network, the USIM card can be applied to a WCDMA, TD-CDMA or LTE network, and the RUIM card and the UIM card can be applied to a CDMA or CDMA2000 network. The SIM card and the UIM card are mobile phone cards (2G mobile phone cards for short) supporting the second Generation mobile communication technology (2G, 2 nd-Generation); the USIM and the RUIM are mobile phones (referred to as 3G mobile phones for short) supporting the third Generation mobile communication technology (3G, 3rd-Generation), and the USIM may also support a mobile phone card (referred to as 4G mobile phone for short) supporting the fourth Generation mobile communication technology (4G, 4 th-Generation).

As an example, the process of applying for and loading the virtual identification card with the server 111 after arriving at the roaming place 141 may be: the mobile terminal 101 may establish a connection and communicate with the server 111 storing the virtual identification card information or with the cloud server to obtain the virtual identification card through the following embodiments: first, a user holding the mobile terminal 101 needs to log in the server 111 or the cloud server based on the login authority that the user has, for example, the authority may be an account number, a biometric characteristic, or the like. The method specifically comprises the following steps: the mobile terminal 101 firstly sends a login request to the server 111 or the cloud server, the server 111 or the cloud server is logged in after passing the verification through a preset authentication mode, the server 111 or the cloud server sends an access response allowing access to the mobile terminal 101, a virtual identification card information downloading request is sent to the server 111 or the cloud server immediately, a downloading process is started after both sides start a data encryption mode, and parameter information (including but not limited to an operator to which the virtual identification card belongs, an ICCID of the virtual identification card, and a class of an operator package to which the virtual identification card currently belongs) of the virtual identification card stored in the server 111 or the cloud server is downloaded to the mobile terminal 101. The user only needs to log in the cloud storage of the user or an account number and a password of the server 111, or other high-level authentication modes (such as a biological characteristic information password) to log in the server 111 or the cloud server, then browses all effective user-level information of the virtual identity card under the current account information of the user, then selects the corresponding virtual identity card according to the user's needs, performs security decoding on the information of the virtual identity card through an Over-the-Air Technology (OTA) mode, writes the information into the security storage of the mobile terminal 111, and then the user selects to activate the security of the corresponding card to normally access the network for use.

In S320, it is determined whether the information of the virtual identification card satisfies a first condition. The virtual identification card information may be PLMN information stored on the virtual identification card. The method specifically comprises the following steps: and judging whether the country of the roaming place where the mobile terminal arrives is consistent with the country of the virtual identity identification card loaded in the roaming place or not according to the PLMN information on the virtual identity identification card. The significance and effect of taking this step are: when the country of the roaming place and the loaded virtual identity recognition card obtained by the user belong to one country or region, the user can directly utilize the virtual identity recognition card to quickly search the network; when the country or region of the roaming place and the virtual id card loaded by the user belong to different countries, respectively, the delay of network searching is significantly slowed down, and the roaming access method shown in fig. 2 is adopted to effectively reduce the delay of network access. The reason why the first condition is satisfied is that: the current virtual identification card downloaded and used by the user is not a local virtual identification card in a strict sense, but is a virtual identification card different from a country of a roaming place, and only has a low use charge at the roaming place of the user. For example, the virtual id card that the user downloads when the virtual id card function is activated in country a is a virtual id card in country B, not a local card in country a. Therefore, the mobile terminal held by the user needs to search for the network of country a based on the virtual identification card of country B. This has the problem that the mobile terminal needs to search the mobile network of country a in a full band. At present, a country generally has a plurality of different operators, and most of the operators have 2G/3G/4G networks at the same time, so when a user starts the virtual identification card function of this type, the mobile terminal needs to spend a long time to search a communication network, which causes poor user experience.

In S330, when the country or region where the roaming place belongs and the virtual id card loaded by the user belong to different countries, the method for accessing the roaming network shown in fig. 2 is performed. As one example, the method of determining that the first condition is satisfied may include: and obtaining the country to which the virtual identity card belongs according to the mobile country code stored on the virtual identity card, and then comparing the country to which the virtual identity card belongs with the country to which the roaming place belongs, wherein the first condition is met if the two are inconsistent. At this time, the specific roaming access method can be simplified as follows: and acquiring at least one group of historical network residing information corresponding to the roaming place, and starting to access the communication network based on the at least one group of historical network residing information.

In S340, accessing the communication network of the roaming place based on the information of the loaded virtual identification card. As one example, the method of determining that the first condition is satisfied may include: and obtaining the country to which the virtual identity card belongs according to the mobile country code stored on the virtual identity card, and then comparing the country to which the virtual identity card belongs with the country to which the roaming place belongs, wherein if the two are consistent, the first condition is not met. The first condition is satisfied, namely the virtual identity identification card loaded by the user is the virtual identity identification card of the country of the roaming place, and at the moment, the mobile terminal can directly search the communication network according to the mobile network code stored by the virtual identity identification card without searching the communication network from the historical network residing information. When the first condition is not met, the baseband unit of the mobile terminal 101 directly starts to search from the frequency point of the country of the roaming place, and searches whether the currently searched frequency point exists in the current network environment, and does not need to start to search whether the frequency point exists in the current network environment from the frequency point divided by the lower frequency band of the operator in other countries, so that the time required for searching the frequency points can be saved.

Fig. 4 schematically illustrates the step of screening the historical network-residing information, so that the mobile terminal 101 can utilize the screened historical network-residing information to more quickly and reasonably camp on the network. Specifically, when the at least one group of historical network residing information is a plurality of groups of historical network residing information, screening the plurality of groups of historical network residing information according to a predetermined condition to obtain historical network residing information meeting the predetermined condition (S410), wherein the predetermined condition is related to the attribute or the state of the mobile terminal; and starting to access the communication network of the roaming place based on the screened historical network residence information (S420).

In S410, the attribute information of the mobile terminal may include: network systems supported by the mobile terminal and other characteristics related to the inherent attributes of the terminal. The state information of the mobile terminal may include: the remaining power of the terminal or the type of service requested by the terminal, etc. are related to a specific state of the mobile terminal at a certain time, and the state information may change over time.

The present invention provides an embodiment in which the mobile terminal 101 sends the network formats it supports to the server 111. The server 111 firstly performs a first screening according to the roaming location information to obtain all location history network-residing information corresponding to the roaming location, and then the server 111 performs a second screening according to the network system supported by the mobile terminal 101 to obtain the final system history network-residing information. After that, the server 111 sends the system history presence information obtained by filtering the history presence information twice to the mobile terminal 101. And finally, the mobile terminal 101 searches the network according to the system historical network residing information and completes network residing.

The present invention also provides another embodiment, in which the server 111 sends all the historical camping information corresponding to the roaming place to the mobile terminal 101. And the mobile terminal 101 filters the historical network-resident information according to the remaining power condition of the mobile terminal. For example, when the remaining power is low, the mobile terminal preferentially searches a communication network from the plurality of sets of historical camping information based on the historical camping information with relatively low power consumption and completes the camping. For example, assuming that the accessible communication networks of the roaming location a have historical presence data displayed therein include three network systems of 2G,3G and 4G, and the mobile terminal requests data services after arriving at the roaming location a and the remaining power of the mobile terminal is only ten percent or less of the maximum storage power, the mobile terminal will preferentially select the historical presence information related to 2G to search for the communication network. And if the residual capacity of the mobile terminal is eighty percent or higher of the maximum storage capacity of the mobile terminal, the mobile terminal preferentially selects the historical network-residing information related to the 4G to search the communication network. Here, ten percent or eighty percent is only an exemplary limitation for illustrating the technical solution, and a person skilled in the art may determine the specific percentage of the remaining power corresponding to the less power or the more power according to the actual situation.

Fig. 5 schematically illustrates a flow chart of an information processing method 500 of an embodiment of the present application. The information processing method 500 is applicable to the server 111 shown in fig. 1.

As shown in fig. 5, the information processing method 500 includes: receiving historical network-residing information uploaded by a first mobile terminal (S510), wherein the historical network-residing information is information used by the first mobile terminal when accessing a communication network of a roaming place; receiving a request for requesting historical web presence information from the second mobile terminal (S520); and providing historical web presence information to the second mobile terminal according to the request (S530).

In S510, the first mobile communication terminal may be a plurality of mobile communication terminals, that is, each mobile terminal accessing the communication network of the roaming place uploads information used when accessing the communication network of the roaming place to the server 111. For example, the first communication terminal may be the mobile terminal 102 shown in fig. 1. The information used when accessing the roaming communication network may include: the system comprises an operator public land mobile network PLMN, a network-residing system (comprising 2G,3G or 4G and the like), frequency band or network-residing cell information and the like.

In S520, the server 111 may be configured to receive a request instruction for requesting the historical network camping information sent by the second mobile terminal, and may also be configured to receive a request short message for requesting the historical network camping information sent by the second mobile terminal. The second mobile terminal may be one physical entity or two different physical entities from the first mobile terminal. For example, the second mobile terminal may be the mobile terminal 101 shown in fig. 1.

In S530, the server 111 may directly provide all the stored historical network camping information corresponding to the roaming destination to the second mobile terminal according to the request, or may provide the historical network camping information obtained through several filtering operations to the second mobile communication terminal.

As an example of S530, the server 111 receives attribute information of the mobile terminal from the second mobile terminal, the attribute information including: the second mobile terminal can support a network system; then, the server 111 searches the network standard corresponding to each group of historical network-residing information from the plurality of groups of historical network-residing information and provides the historical network-residing information corresponding to the network standard that can be supported by the second mobile terminal.

As another example of S530, the server 111 receives, from the second mobile terminal, status information of the mobile terminal, the status information including: the electric quantity information of the second mobile terminal and the requested service type; then, the server 111 counts the power consumption and the service types that can be provided of each set of historical presence information, and selects at least one set of historical presence information that best matches the mobile terminal to provide to the second mobile terminal. For example, when the remaining power of the mobile terminal is less than thirty percent of the total power of the mobile terminal, if the type of the service requested by the mobile terminal is data service, the server 111 preferentially provides the mobile terminal with historical network camping information corresponding to the 2G network type, so that on one hand, 2G is most power-saving relative to 3G and 4G, and on the other hand, the 2G network can also provide basic data service.

According to the technical scheme for the roaming access method, the mobile terminal requests the server for the historical network-residing information and starts network access according to the historical network-residing information received from the server, so that the time for a user to search for a network can be effectively shortened, and the use experience of the user is effectively improved.

For example, the location information may be longitude and latitude information of a current location of the mobile communication terminal 101. In addition, the locator 650 of the mobile terminal 600 may be activated when the current location information of the mobile terminal needs to be acquired, and the current location information of the mobile terminal may be acquired through the locator 650 and then input to the locating unit 710 for comparison processing. For example, the locator 650 may be a GPS locator, a beidou locating device, a GPS beidou dual-mode locating device, or the like.

The network access device 700 (e.g., mobile terminal 600) is communicatively coupled to a server 111. At this time, the information acquiring unit 720 may include: a transmitting unit 721 configured to transmit location information of the mobile terminal at the roaming place to the server 111; and a receiving unit 722 configured to receive at least one set of historical camping information corresponding to the location information of the roaming place from the server 111. For example, the transmitting unit 721 encodes the position information to be transmitted, modulates the position information with baseband and rf, and transmits the result to the server 111 via the antenna. After that, the server 111 searches for historical network camping information corresponding to the location information according to the location information reported by the information obtaining unit 720 included in the network access device 700, and sends the queried historical network camping information to the receiving unit 722. The receiving unit 722 decodes the received information to obtain at least one set of historical network-residing information. As an example, the historical presence information may include: the PLMN of the operator who successfully resides in the network, the network residing system (including 2G,3G or 4G, etc.), the frequency band and the cell information of the network residing. The public land mobile network PLMN in turn comprises a mobile country code and a mobile network code.

Specifically, the virtual id card obtaining and loading unit first obtains the virtual id card based on the memory 660 and the processor unit 630 described in fig. 6, and then the virtual id card obtaining and loading unit writes the obtained information of the virtual id card into the modem of the mobile communication terminal (i.e. the loading is completed). The memory 660 is used for storing an execution code related to acquiring the virtual identification card, and when the mobile terminal needs to acquire the virtual identification card, the processor unit 630 reads the corresponding code from the memory 660 and executes the code. Processor element types may include a general purpose processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), an off-the-shelf programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, and the like.

As an example, the decision processing unit 702 determines whether the first condition is satisfied according to the following principle: the decision processing unit 702 decides that the first condition is satisfied if the country or region to which the roaming place belongs is not identical to the country or region to which the virtual identification card belongs. If the decision processing unit 702 decides that the information of the virtual identification card does not satisfy the first condition that the country or region of the roaming place is identical to the country or region to which the virtual identification card belongs (i.e., both belong to the same country or region), the access unit 730 accesses the communication network of the roaming place based on the loaded information of the virtual identification card. The function of the decision processing unit 702 can be implemented based on the storage unit 630 and the processing unit 660 in fig. 6, specifically, the storage 660 is used for storing an execution code related to the function implemented by the decision processing unit, and when the mobile terminal needs to decide whether the first condition is met, the processor unit 630 reads the corresponding code from the storage 660 and executes the code. The access unit 730 may comprise a frequency point scanner or a frequency locker, etc.

As an example, the virtual identification card acquiring and loading unit 701 is further configured to download and pre-store the virtual identification card of the roaming place before reaching the roaming place; or the virtual identification card of the roaming place is downloaded and stored after the virtual identification card arrives at the roaming place.
