【具体实施方式】【detailed description】

The present invention provides a mobile device communication method and a mobile device, which can enable communication when the mobile device is used in different carrier networks.

The technical solutions of the present invention are separately described in detail below with reference to the accompanying drawings.

Figure 1 is a first flow chart of the method of the present invention, comprising the steps of:

Step 101: The mobile device receives a call, where the mobile device has at least two customer identification module SIM cards;

Step 102: After determining that the call corresponds to the secondary card in the SIM card, determine whether the secondary card is locked.

Step 103: After determining that the secondary card is locked, terminate the call.

Step 104: Prompt the user to use the primary card in the SIM card to call back the calling number.

It can be found that, by using the above processing flow, different cards are authorized to have different rights, so that the communication function of the secondary card is not simply prohibited from being used, and the normal communication can be realized by cooperating with the primary card.

Figure 2 is a second flow chart of the method of the present invention. Compared with Figure 1, Figure 2 illustrates the technical solution of the present invention in more detail.

The secondary card in the method of the present invention has the right to accept an incoming call, but does not have the right to answer under certain conditions, but is called back by the primary card, and cooperates with the primary card to achieve normal communication. The method flow of the present invention begins by receiving an incoming call from a user's mobile device.

The following is introduced in conjunction with the drawings. As shown in Figure 2, the steps are included:

Step 201: The user's mobile device receives the call.

The mobile device has at least two customer identification module SIM cards, one as a primary card and one as a secondary card. The secondary card has the right to accept incoming calls.

Step 202, it is determined whether the call comes from the secondary card, and if so, proceeds to step 203, and if not, proceeds to step 210;

This step can be based on the mobile subscriber's telephone number MSISDN (Mobile Subscriber) in the call parameters. International ISDN/PSTN Number) Compared with the mobile subscriber's telephone number of the primary card, if it is not the mobile subscriber's telephone number of the primary card, it is determined that it is the number in the calling secondary card. Therefore, if the call is not from the secondary card, the process directly proceeds to step 210, and the normal answering call can be performed. This method is not described in detail. If the call comes from the secondary card, proceed to step 203;

Step 203, it is determined whether the secondary card needs to be locked, and if so, proceeds to step 204, and if not, proceeds to step 210;

In this step, the secondary card lock flag bit can be used to determine whether the secondary card needs to be locked. For details, refer to the flow description in FIG. If it is not locked, the process directly proceeds to step 210, and a normal answering call can be performed. This method is not described in detail. If it is locked, proceed to step 204;

It should be noted that the lock of SIMlock is usually commercially available for a certain period of time. If the lock time limit is exceeded, the device does not need to limit the unidentified card, so the judgment process of this step may exist.

Step 204, ending the secondary card call, and recording the call number;

When the secondary card is locked, the software in the mobile device will immediately stop responding to the call. Generally, in the software, various methods can be used to stop responding to calls, such as rejecting incoming calls, outputting busy tones, and the like. This method does not limit the operation.

Step 205, prompting the user that the secondary card is locked;

Step 206: Ask the user whether to use the primary card to call back the call;

Step 207, it is determined whether the user chooses to use the primary card to call, and if so, proceeds to step 208, and if not, proceeds to step 210;

This step waits for the user to make a selection. If the user selects No, the user directly exits the answering interface, and proceeds to the normal processing flow of step 210, and can perform a normal reject call; if the user selects yes, then proceeds to step 208;

Step 208: Start a dialing procedure, and set a call number received by the secondary card as a primary card calling number;

Step 209: The primary card performs callback according to the set call number.

This step is called according to the existing conventional procedure.

Step 210, a normal processing flow.

This step is an existing normal processing procedure, such as performing a normal answer or performing a normal rejection.

The foregoing process can be seen that the method of the present invention achieves the purpose of optimizing the service of the operator by granting different service rights to different SIM cards. Specifically, when the mobile device receives the call, it determines whether the call corresponds to the SIM. The secondary card in the card further determines whether the secondary card is locked after determining the corresponding secondary card, and if so, terminates the call and prompts the user to use the primary card in the SIM card to call back the calling number. Through such a processing flow, the communication function of the secondary card is not simply prohibited from being used, and the normal communication can be realized by cooperating with the primary card, so that the user can be more conveniently realized among different operators. The conversion also enables operators to better attract users.

Figure 3 is a third flow chart of the method of the present invention. FIG. 3 mainly introduces the sub-card lock determination step in FIG. 2 in more detail. This process is usually in the process of starting the device.

As shown in Figure 3, the steps are as follows:

Step 301: Read the mobile network code MNC of the primary card (ie, the primary SIM card) (Mobile Network Code) and Mobile Country Code (MCC) information;

The resources of the MCC are uniformly allocated and managed by the ITU (ITU) to uniquely identify the country to which the mobile subscriber belongs, a total of 3 digits, and China is 460; the MNC has 2 digits, which is used to identify the network to which the mobile subscriber belongs.

The method of the present invention presets an operator whitelist within the mobile device, i.e., a list of codes of its approved MCC and MNC, typically designated by the operator. For SIM cards that are not in the whitelist, restrictions will be imposed on related functions, such as not being able to make calls, sending text messages, surfing the Internet, etc., or directly locking the mobile device.

Step 302: Check a SIMLock condition.

This step is mainly to check whether the MNC and MCC are in the code list of the license usage stored in the device. If it exists, it means that it is verified by SIMLock. If it does not exist, it means that it has not passed the verification, then the international standard SIM operation is performed, that is, the entire device should be locked, and all functions except the emergency call (SOS) function are prohibited. Unless the user enters an unlock code; the aforementioned processing method of the present invention is not performed.

Step 303, it is determined whether the primary card is available, and if so, proceeds to step 304, and if not, proceeds to step 308;

This step determines whether the primary card is available according to the check result of step 302. If the SIMLock is verified, the primary card is available, otherwise it is unavailable.

Step 304: Read MNC and MCC information of the secondary card (ie, the secondary SIM card);

Step 305: Check a SIMLock condition.

This step is mainly to check whether the MNC and MCC are in the code list of the license usage stored in the device. The principle is the same as step 302, and will not be described again.

Step 306: Determine whether the secondary card is unusable, and if yes, proceed to step 307. If no, the process ends, and the secondary card can be used normally;

This step determines whether the secondary card is unusable according to the check result of step 305. If the MNC and the MCC fail to pass the verification, it is determined that the secondary card is locked. If the verification is passed, the secondary card is not locked, and the secondary card is locked without being marked, and the normal operation can be performed.

Step 307, the marked secondary card is locked and cannot be used;

This step marks the secondary card lock, which can be marked with a value of a set flag in the memory, for example, a value of 1 indicates a lock, and a value of 0 indicates an unlock, etc., of course, the opposite value can also be used, and the present invention does not Limit it. In addition, the present invention does not limit the specific memory location.

Step 308, locking, prompting the user to input unlock information.

This step performs the international standard SIM operation, ie the entire device should be locked, and all functions except the emergency call (SOS) function are prohibited unless the user enters the unlock code.

SIMLock verification is to disable some functions of the SIM card that does not meet the requirements from the software perspective. Although the secondary card does not meet the requirements, from the software point of view, the bottom layer of the system can still read the data on the SIM card, such as the phone number on the SIM card. And the key parameters and respond to the corresponding operations, which is also fundamentally different from the user's ability to respond directly to the operation.
