detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings.

The embodiment of the present invention provides a SIM information management method, which is used for a mobile terminal, and the mobile terminal may be a mobile phone, or a tablet computer and a wearable device having a SIM, which is not limited by the embodiment of the present invention, as shown in FIG. 1 . Show, including:

Step 101: Acquire SIM information corresponding to a roaming destination, where the SIM information includes The SIM card number that is sufficient for the roaming destination.

Generally, if the user can predict the roaming destination, the SIM server provided by the home operator can be downloaded and the SIM information corresponding to the roaming destination can be downloaded before the roaming, and the SIM server stores multiple SIM addresses according to different roaming places. SIM information, the user can download the corresponding SIM information according to the roaming destination. For example, if the home location of the mobile phone is Xi'an, the SIM server provided by the home operator stores three roaming sites, and each roaming site has two SIM information, as shown in Table 1, and Table 1 is the home carrier. A list of SIM information stored by the provided SIM server.

Table 1

漫游地Roaming place	SIM信息SIM information
美国United States	第一SIM信息，第二SIM信息First SIM information, second SIM information
日本Japan	第三SIM信息，第四SIM信息Third SIM information, fourth SIM information
韩国Korea	第五SIM信息，第六SIM信息Fifth SIM information, sixth SIM information

When the user predicts that the roaming destination is the United States, the first SIM information or the second SIM information may be downloaded in advance on the SIM server provided by the home operator.

If the user cannot predict the roaming destination, the corresponding SIM information may also be downloaded on the SIM server provided by the roaming operator after reaching the roaming destination. Assuming that the mobile phone is located in Xi'an, the user is temporarily told to travel to Korea, and it is too late to download the corresponding SIM information. After the user can arrive in Korea, he can log in to the Korean operator through Wireless Fidelity (Wi-Fi) in South Korea. The SIM information of the response is downloaded from the SIM server, or the mobile phone automatically connects to the network of the operator that temporarily provides the emergency service to the mobile phone, and then downloads the corresponding SIM information on the SIM server provided by the operator through the network.

Step 102: Activate the SIM information, so that the mobile terminal can use the SIM card number to perform a service including a voice call at the roaming destination, and enable the mobile terminal to perform a voice call including using a home number. business.

Generally, after the user selects the corresponding SIM information, the selected SIM information may be activated. Specifically, the activation request may be sent to the communication network of the roaming operator corresponding to the SIM information, where the activation request includes the mobile The home number of the terminal, the SIM card number included in the SIM information, the SIM card number is the roaming number used by the user at the roaming destination, and after the communication network receives the activation request, the roaming number is first opened. Related services, that is, enabling a mobile terminal to perform a service including a voice call using the SIM card number at the roaming destination, or may further include a service such as a short message or a data transmission of a communication network; and then associated the home number and the roaming number When another user dials the home address of the mobile terminal, the communication network of the home operator of the mobile terminal sends the call signal to the communication network of the roaming operator, and then the communication network of the roaming operator dials the call. Transmitting the signal to the mobile terminal, enabling the mobile terminal to include using the home number Voice call business, or you can also use SMS services.

In this way, when the mobile terminal performs roaming, the mobile terminal can make the voice call roaming by activating the SIM information, and the mobile phone can also perform a voice call through the home number, thereby satisfying the call requirement of the user in the roaming place. And since there is no need to replace the SIM card for the mobile phone, the user is convenient and the user experience is improved.

Optionally, the SIM information further includes a file validity period, configured to indicate a storage time limit of the SIM information on the mobile terminal; before the SIM information is activated, the SIM information may be first determined to be in the mobile terminal. Whether the storage time is within the validity period of the file, and when the SIM information is stored in the mobile terminal for a period of validity of the file, the SIM information is activated.

For example, since each operator can use a limited number of SIM card segments, the operator needs to allocate a limited number of SIM card numbers from these segments for setting SIM information, so the SIM information provided by each operator for downloading is also Limited, so the operator can set the file validity period for each SIM information, which is used to indicate the maximum time limit for the user to download the SIM information, when the user downloads The SIM information is not activated for a long time, and when the storage time exceeds the file validity period of the SIM information, the SIM information is invalid and cannot be activated, and the SIM information can be downloaded and used by other users in need. Therefore, before the mobile terminal sends the activation information to the operator, it may first determine whether the storage time of the SIM information in the mobile terminal is within the validity period of the file, or whether the storage time of the SIM information in the mobile terminal is less than The preset duration is the file validity period, and can be set to two weeks. When the SIM information is stored in the mobile terminal, the SIM information is activated.

Optionally, the SIM information further includes a parameter of a roaming operator that provides the mobile terminal with the roaming destination; before the SIM information is activated, the operation in the SIM information may also be first determined. Whether the parameters of the quotient are the same as the parameters of the operator currently providing the service, and when the parameters of the roaming operator in the SIM information are the same as the parameters of the operator currently providing the service, the SIM information is activated.

The parameters of the operator include the name of the operator, the Mobile Country Code (MCC) and the Mobile Network Code (MNC), etc., which are inherent characteristics of each operator. For example, after the mobile terminal moves to the roaming destination, the roaming destination includes two operators, namely, a first operator and a second operator, where the first operator can be the field for all the roaming destinations. The mobile terminal provides emergency service, so when the mobile terminal enters the roaming destination, it automatically accesses the communication network of the first operator, but the user may choose to download the SIM information provided by the second operator, so the activation cannot be performed, so The SIM information is activated when the parameters of the roaming operator in the SIM information are the same as the parameters of the operator currently providing the service; when the parameters of the roaming operator in the SIM information are related to the operator currently providing the service When the parameters are different, the user's SIM information may be prompted to be inconsistent with the current communication network. The user may choose to download the SIM information provided by the first operator, or may choose to switch the operator.

Optionally, the SIM information further includes an expiration date used to indicate the SIM information. Period of use. After the activation of the SIM information, it may also be determined whether the current usage time exceeds the validity period of the SIM information, and when the current usage time exceeds the validity period of the SIM information, the user is prompted to download new SIM information.

For example, if the user plans to settle in the roaming destination for a long time, in order to facilitate the convenience of living and working in the future, the mobile phone number is usually selected instead of downloading the SIM information, so the users who choose to download and use the SIM information are all planned to be short in the roaming destination. Inhabited, so the operator can set a validity period for each SIM message to indicate the period during which the SIM information can be used. When the SIM information is activated, the usage period is also activated, and can be used normally only during the use period. During normal use, the mobile terminal can determine whether the current usage time exceeds the validity period of the SIM information and the current usage time. When the validity period of the SIM information is exceeded, the prompt information is displayed to prompt the user to download new SIM information. If the user has returned to the home location, the prompt information may also be ignored.

Optionally, when acquiring the SIM information corresponding to the roaming destination, the SIM server provided by the home operator of the mobile terminal may be logged in, where the SIM server stores at least one SIM information, and each SIM information corresponds to one area. And then download the SIM information of the area corresponding to the roaming destination. It is also possible to download the usable SIM information on the SIM server provided by the roaming operator after reaching the roaming destination.

An embodiment of the present invention provides a SIM information management method, where the method includes first acquiring SIM information corresponding to a roaming destination, where the SIM information includes a SIM card number that can be used at the roaming destination; and then activating the The SIM information enables the mobile terminal to perform a service including a voice call using the SIM card number at the roaming destination, and enables the mobile terminal to perform a service including a voice call using a home number. Compared with the prior art, when the mobile terminal performs roaming, the mobile terminal can make the voice call roaming by activating the SIM information, and the mobile phone can also perform a voice call through the home number, satisfying the user's roaming location. Call needs, and because there is no need to replace the SIM card for the phone, it is convenient The user has improved the user experience.

The embodiment of the present invention provides a SIM information management method for a mobile terminal. The embodiment of the present invention is assumed to be a first location, where the roaming destination includes two operators, which are a first operator and a second operator, respectively. Specifically, as shown in FIG. 2, the method includes:

Step 201: Log in to the SIM server.

For example, if the user can predict the destination of the roaming, the SIM server provided by the home operator can be logged in at the home location; if the user cannot predict the destination of the roaming, the roaming can be logged in through the wireless local area network after reaching the roaming destination. The SIM server provided by the operator of the destination, since the roaming destination includes the first operator and the second operator, the mobile terminal may choose to log in to the SIM server provided by the first operator, or may choose to log in to the second server. The SIM server provided by the operator.

Step 202: Download SIM information corresponding to the roaming destination from the SIM server according to the roaming destination, and perform step 203.

The SIM information includes a SIM card number that can be used at the roaming destination, a file validity period, a validity period, and a parameter of a roaming operator that provides the mobile terminal with the roaming destination.

If the user can predict that the destination of the roaming is the first location, the mobile terminal logs in to the SIM server provided by the home operator, and the server stores a plurality of different SIM information according to the location. Specifically, as shown in Table 2, the table 2 A SIM information list of the first location stored by the SIM server provided by the home operator.

Table 2

Table 2 describes that the SIM server provided by the home operator stores SIM information of two operators at the first location, where each operator corresponds to two SIM information. At this time, the user may select to download any one of the first SIM information, the second SIM information, the third SIM information, and the fourth SIM information according to the preference or the cooperation relationship between the operators, and the embodiment of the present invention assumes that the user is at home. The first SIM information corresponding to the first carrier is downloaded.

If the user cannot predict that the destination of the roaming is the first location, after the user arrives at the first location, the user may log in to the SIM server provided by the first operator, and the server stores SIM information that can be downloaded by the foreign mobile terminal, as shown in Table 3. As shown, Table 3 is a list of SIM information stored by the SIM server provided by the first operator.

table 3

Table 3 describes the SIM information corresponding to the first carrier stored on the SIM server provided by the first operator, and the user may choose to download any one of the first SIM information or the second SIM information.

If the user cannot predict that the destination of the roaming is the first location, after the user arrives at the first location, the user may also log in to the SIM server provided by the second operator, and the server stores SIM information that can be downloaded by the foreign mobile terminal, such as a table. As shown in FIG. 4, Table 4 is a list of SIM information stored by the SIM server provided by the second operator.

Table 4

运营商Operator	SIM信息SIM information
第二运营商Second operator	第三SIM信息Third SIM information

Fourth SIM information

Table 4 describes SIM information corresponding to the second operator stored on the SIM server provided by the second operator, and the user may select to download any one of the third SIM information or the fourth SIM information.

Step 203: After the user arrives at the roaming destination, determine the SIM information corresponding to the roaming destination, and perform step 204.

Generally, the SIM information of the multiple locations can be pre-stored in the mobile terminal, so that the user can use the roaming when the roaming is performed. Therefore, after the user arrives at the first location, the SIM information corresponding to the first location is first determined from the pre-stored multiple SIM information. .

Step 204: Determine whether the storage time of the SIM information on the mobile terminal is within a file validity period; when the storage time of the SIM information on the mobile terminal is within a file validity period, perform step 205; When the storage time of the SIM information on the mobile terminal exceeds the file validity period, step 209 is performed.

For example, suppose the first operator can use the number 1333*******~1335*******, and the second operator can use 1337*******~1339*** The number of the ****, in which the first operator sets 13330******~13335****** in the number segment as the SIM card number used by the SIM information, and the first carrier will be the number segment. 13370******~13395****** in the setting is the SIM card number used for SIM information. In order to ensure the rational use of resources and improve resource utilization, both the first operator and the second operator are valid for the SIM information setting file, and the validity period of each SIM information file is 2 weeks. It is assumed that the mobile terminal downloads the first SIM information of the first operator, and before the activation of the first SIM information, it may first determine whether the storage time of the first SIM information on the mobile terminal is less than a preset duration, that is, determine the first Whether the storage time of the SIM information exceeds the validity period of the file. If the first SIM information is not used for two weeks after the mobile terminal downloads the first SIM information, the first SIM information is automatically invalidated, and other users can be on the SIN server if necessary. The first SIM information is downloaded again.

Step 205: Determine the parameters of the operator in the SIM information and the current service delivery service. Whether the parameters of the operator are the same; when the parameters of the operator in the SIM information are the same as the parameters of the operator currently providing the service, step 206 is performed; when the parameters of the roaming operator in the SIM information are currently provided When the parameters of the service provider are different, step 209 is performed.

For example, it is assumed that the second operator of the first location can provide emergency services for all foreign mobile terminals, so when the mobile terminal arrives at the first location, it automatically accesses the communication network of the second operator, but the SIM information downloaded by the mobile terminal The first SIM information of the first carrier cannot be activated at the time due to network incompatibility. Therefore, when the SIM information is activated, it is also required to determine whether the parameters of the operator in the SIM information are the same as the parameters of the operator currently providing the service, so as to avoid waste of resources caused by the failure to activate.

Step 206: Activate the SIM information, and perform step 207.

For example, when the storage time of the first SIM information on the mobile terminal is less than a preset duration, and the parameters of the operator in the first SIM information are the same as the parameters of the operator currently providing the service, the first SIM may be used. The information is activated. Specifically, the activation request may be sent to the communication network of the first operator, where the activation request includes a home address of the mobile terminal, a SIM card number included in the first SIM information, and the SIM card number is a user. After receiving the activation request, the first carrier's communication network first activates the related service of the roaming number, that is, enables the mobile terminal to use the roaming number at the first location. The service includes a voice call, or may also include a short message, a data transmission of a communication network, and the like. Then, the communication network of the first carrier may also associate the home number with the roaming number, and simultaneously send the association information of the home number and the roaming number to the home operator of the mobile terminal, indicating the association between the home number and the roaming number. relationship. In this way, when another user dials the home address of the mobile terminal, the communication network of the home operator of the mobile terminal sends the call signal to the communication network of the first operator, and then the communication network of the first operator. The dialing signal is forwarded to the mobile terminal, so that the mobile terminal can still use the home number to perform the service including the voice call at the first location, or can also use the short message service.

In step 207, it is determined whether the current usage time is within the validity period of the SIM information. If the current usage time is within the validity period of the SIM information, step 210 is performed. If the current usage time exceeds the validity period of the SIM information, step 208 is performed.

Illustratively, since the mobile terminal that downloads the SIM information usually only temporarily resides at the roaming destination, the roaming operator can set a lifespan for each SIM to avoid causing the user to not use the resources of the activated SIM information, but Resources are not wasted by other users. It is assumed that the first operator sets the validity period of the first SIM information to be one month, that is, after the first SIM information is activated, the mobile terminal can normally use one month. After the first SIM information is activated, the usage period is also activated. During the normal use of the mobile terminal, it can be periodically determined whether the current usage time exceeds the validity period of the first SIM information, that is, whether the current usage time exceeds one month.

Step 208: prompting the user that the SIM information has expired, and prompting the user to download new SIM information, and ending the processing flow.

For example, if the current usage time exceeds the validity period of the first SIM information, indicating that the first SIM information is currently unavailable, the mobile terminal may prompt the user that the first SIM information has expired, and may also prompt the user to download a new SIM. information. If the user still needs to continue to stay at the roaming destination, he can download the new SIM information according to the prompt to activate; if the user has returned to the home location, and does not need to continue to use the SIM information, he can choose to ignore the prompt.

Step 209, prompting the user to download new SIM information, and ending the processing flow.

For example, when the storage time of the first SIM information on the mobile terminal is greater than or equal to the preset duration, indicating that the file validity period of the first SIM information has been exceeded, the resources of the first SIM information have been released for other needs. The mobile terminal performs the download. Therefore, when the mobile terminal determines that the storage time of the first SIM information on the mobile terminal is greater than or equal to the preset duration, the user may be prompted to download new SIM information.

Alternatively, the mobile terminal downloads the first SIM information of the first carrier, but currently provides The service is the second carrier. At this time, it can be determined that the parameters of the operator in the first SIM information are different from the parameters of the operator currently providing the service, that is, the first SIM information cannot be performed because the network is incompatible. The mobile terminal can prompt the user to download new SIM information, and the new SIM information can be any one of the second operator's SIM information.

Step 210: Normally use the mobile terminal.

The embodiment of the present invention provides a SIM information management method. When a mobile terminal performs roaming, the mobile terminal can make a voice call roaming by activating the SIM information, and the mobile phone can also perform a voice call through the home number. The user needs to talk at the roaming place, and since it is not necessary to replace the SIM card for the mobile phone, the user is convenient and the user experience is improved.

It should be noted that the sequence of steps of the SIM information management method provided by the embodiment of the present invention may be appropriately adjusted. For example, step 204 and step 205 may be mutually exchanged, and the steps may also be correspondingly increased or decreased according to the situation, and any familiar technical field. Those skilled in the art can easily conceive changes in the scope of the present invention, and are not included in the scope of the present invention.
