Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention provides a network registration method, which is applied to a dual-card mobile terminal having two card slots and two inserted SIM cards, where the two card slots include a preset primary card slot and a preset secondary card slot, and after two SIM cards are pulled out and then inserted into the two card slots again, the method includes the following steps:

s1, judging whether the two SIM cards are subjected to position exchange after being pulled out and then are reinserted into the two card slots;

s2, if the position is exchanged and then the SIM cards are inserted into the two card slots again, judging whether the two SIM cards finish network attachment;

s3, if the network attachment is not completed, no card cutting instruction is sent; and if the network attachment is finished, sending a card cutting instruction, setting the SIM card in the preset main card slot as a main card, and setting the SIM card in the preset auxiliary card slot as an auxiliary card.

In this embodiment, the mobile terminal stores that the card slot corresponding to the most recently set main card is the preset main card slot, and the card slot corresponding to the most recently set sub-card is the preset sub-card slot. For example, the user sets the primary card and the secondary card through the human-computer interaction interface of the mobile terminal for the last time, at this time, the card slot corresponding to the primary card is the preset primary card slot, and the card slot corresponding to the secondary card is the preset secondary card slot.

In step S1, the user pulls out the two SIM cards and then inserts them into the two card slots again, and first determines whether the user has performed physical exchange with the original main and auxiliary card positions. If position exchange is not carried out, the setting of the card slot is consistent with the setting of the SIM card about the main card and the auxiliary card, the main card and the auxiliary card do not need to be switched, and the two SIM cards directly carry out startup network attachment according to the originally set main card/auxiliary card. If the position is exchanged, the main card and the auxiliary card need to be switched for the two SIM cards.

In step S2, the network attach refers to the SIM card performing network attach during the power-on and network-finding of the mobile terminal. If step S1 determines that the two SIM cards have exchanged positions, the card-cutting command is generated but the execution of the card-cutting command is not urgently issued. After the card-cutting instruction is issued, the SIM card can obtain an instruction for performing network detachment. At this time, if the SIM card has not completed network attachment, and the SIM card receives a network detachment instruction, the SIM card interacts with the network repeatedly, and network attachment and network detachment are performed repeatedly, which results in an abnormal network attachment process, prolongs the time for cutting the card and registering the network again, and causes extra time consumption of tens of seconds, and the speed for cutting the card and starting the network is slow. Therefore, step S2 first determines whether the two SIM cards have completed network attachment, and the card-cutting instruction is not issued for the moment, so as to separately execute the network attachment and the card-cutting process of the SIM cards.

In step S3, the above-mentioned case where network attachment is not completed means that network attachment is not completed for both cards, and there is a case where network attachment is not completed for one card. When the two SIM cards do not finish the network attachment, the card cutting instruction is not sent down firstly, so as to avoid causing the abnormity of the network attachment process. If step S2 determines that both cards complete the network attach procedure, a card-cutting instruction is issued, and the SIM card in the current preset primary card slot is set as the primary card and the SIM card in the current preset secondary card slot is set as the secondary card. At the moment, the card cutting instruction is executed again, so that the conflict between the card cutting instruction and the network attachment of the SIM card is avoided, the network registration is performed orderly, the network-up delay caused by abnormal network attachment is avoided, and the card cutting and network-up speed is accelerated.

Referring to fig. 2, the step S1 of determining whether the two SIM cards are pulled out, exchanged in position, and reinserted into the two card slots further includes:

s101, judging whether the ICCID of the SIM card in the preset main card slot is a preset main card ICCID and/or judging whether the ICCID of the SIM card in the preset auxiliary card slot is a preset auxiliary card ICCID, wherein the preset main card refers to the SIM card in the preset main card slot which is set at the moment closest to the current time, and the preset auxiliary card refers to the SIM card in the preset auxiliary card slot which is set at the moment closest to the current time;

s102, if yes, judging that position exchange is not carried out and then reinserting the two card slots;

s103, if not, judging that the position is exchanged and reinserting the two card slots.

In this embodiment, in step S101, the mobile terminal may read the ICCID of the SIM card inserted into the card slot, and the reading method is the prior art and is not described here again. The ic id (integrated circuit card identity) is an integrated circuit card identification code, i.e. a SIM card number, which is a unique identification code of the SIM card, and is composed of 20 digits, and its encoding format is XXXXXX0MFSS YYGXX XXXX. And the information of the operator, province and the like corresponding to the SIM card can be read through different data of each position in the ICCID.

In the step S102, by comparing the ICCID of the SIM card in the preset main card slot with the ICCID of the preset main card, if the two SIM cards are the same, it indicates that the two SIM cards are not exchanged after being pulled out, or are inserted into the card slot according to the original sequence, that is, the SIM card in the preset main card slot is the main card in the mobile phone last time, and the newly inserted main card slot is still the main card slot, so that the subsequent card cutting operation is not required.

In step S103, by comparing the ICCID of the SIM card in the preset main card slot with the ICCID of the preset main card, if they are different, it indicates that the two SIM cards are exchanged after being pulled out, that is, the SIM card in the preset main card slot is the secondary card in the mobile phone last time, and the secondary card is the main card slot, and at this time, the card slot of the mobile terminal and the SIM card are not consistent with each other regarding the setting of the main card/secondary card, and then subsequent card cutting operation is required.

In step S103, after determining that the position is changed and the mobile terminal is reinserted into the two card slots, the mobile terminal generates a card-cutting instruction, but does not issue the card-cutting instruction once. And further updating the ICCID of the SIM card currently inserted into the preset main card slot to the latest preset main card ICCID, and updating the ICCID of the SIM card currently inserted into the preset auxiliary card slot to the latest preset auxiliary card ICCID. In this embodiment, because two SIM cards are targeted, it can be determined whether two SIM cards are exchanged or inserted in the original order only by determining whether the SIM card in one card slot is the original SIM card. Of course, the effect of this embodiment can also be achieved by determining whether the SIM cards in the main card slot and the auxiliary card slot are the original SIM cards.

Referring to fig. 2, before step S101 of determining whether the ICCID of the SIM card in the preset primary card slot is the preset primary card ICCID and/or determining whether the ICCID of the SIM card in the preset secondary card slot is the preset secondary card ICCID, the method further includes:

s100, obtaining the preset primary card ICCID and/or obtaining the preset secondary card ICCID.

In this embodiment, the preset main card refers to a SIM card in the preset main card slot set at the time closest to the current time, the mobile terminal obtains and stores the ICCID of the preset main card, and compares the ICCID of the SIM card newly inserted into the preset main card slot with the ICCID of the preset main card, if the two ICCIDs are the same, it indicates that the SIM card in the preset main card slot is in the preset main card slot before being pulled out, and if the two ICCIDs are different, it indicates that the SIM card in the preset main card slot is in the preset auxiliary card slot before being pulled out. Similarly, the preset secondary card refers to a SIM card in the preset secondary card slot set at the time closest to the current time, the mobile terminal obtains and stores the ICCID of the preset secondary card, and the ICCID of the SIM card newly inserted into the preset secondary card slot is compared with the ICCID of the preset secondary card, if the two ICCIDs are the same, it indicates that the SIM card in the preset secondary card slot is in the preset secondary card slot before being pulled out; if the SIM card is different from the preset primary card slot, the SIM card in the preset secondary card slot is indicated to be in the preset primary card slot before being pulled out.

Further, before the step S1 of determining whether the two SIM cards are pulled out, and then are subjected to position exchange and reinserted into the two card slots, the method further includes:

and S01, under a preset condition, supplying power to the preset main card slot and the preset auxiliary card slot, and starting startup initialization of the SIM card in the preset main card slot and the SIM card in the preset auxiliary card slot.

In this embodiment, after the two SIM cards are reinserted, the mobile terminal supplies power to the two card slots again, and each PIN of the card slot interface contacts with each PIN of the SIM card to detect that the SIM card is inserted, query the PIN locking states of the SIM cards of the two card slots, obtain the states from the card slots through the driver layer, and then transmit the message to the message processing layer for receiving and processing. In addition to identifying the PIN lock state of the SMI card, the system state information, summary and comprehensive processing information, loading a graphical interface portion, and the like need to be acquired and cached in the boot initialization stage, and the boot initialization needs to be performed for several seconds to tens of seconds.

Further, the step S01 of starting the power-on initialization for the SIM card in the preset primary card slot and the SIM card in the preset secondary card slot includes:

s011, starting network attachment for the SIM card in the preset main card slot and the SIM card in the preset auxiliary card slot;

s012, acquiring the latest main/auxiliary card state of the SIM card in the preset main card slot, and correspondingly setting the SIM card in the preset main card slot as a main/auxiliary card; and acquiring the latest main/auxiliary card state of the SIM card in the preset auxiliary card slot, and correspondingly setting the SIM card in the preset auxiliary card slot as the main/auxiliary card.

In this embodiment, in step S011, after the two SIM cards are reinserted, the mobile terminal starts to check the cards, and when the wireless states are synchronized, the mobile terminal sends a network start instruction, and the two SIM cards start network attachment. For a one-way authenticated GSM network, the network attach procedure is as follows: the Mobile terminal sends a network access request to the network, the network replies a string of random character strings, the Mobile terminal receives and transmits the string of random character strings to the SIM card, the SIM card calculates according to a preset algorithm and returns a calculation result to the Mobile terminal, the Mobile terminal sends the calculation result, IMEI (International Mobile Equipment Identity) and ICCID back to the network, the network reads the ICCID and analyzes whether the number is a local number or not, and the network returns a legal message to finish the network attachment process. For the bidirectional authentication network, not only the network needs to identify whether the user is legal or not in the network attachment process, but also the user needs to identify whether the network is legal or not, and after the bidirectional authentication is legal, the network attachment process is completed, and specific steps are not described herein again.

In step S012, the latest primary/secondary card status of the SIM card in the preset primary card slot and the latest primary/secondary card status of the SIM card in the preset secondary card slot are obtained, and in the power-on initialization step, the obtained card statuses are summarized and processed by the preset primary card logic, so as to determine which of the two SIM cards is set as the primary card most recently. If the SIM card in the preset main card slot is set as the main card for the last time, the SIM card in the preset main card slot is set as the main card in the starting initialization stage, otherwise, the SIM card is set as the auxiliary card. The primary/secondary card setting step of the SIM card in the preset secondary card slot is the same as the setting step of the SIM card in the preset primary card slot, and is not described here again.

In this embodiment, hot plugging, that is, hot plugging, allows a user to take out and insert an SIM card without closing the mobile terminal system.

Referring to fig. 3, further, the step S3 of setting the SIM card in the preset primary card slot as the primary card and setting the SIM card in the preset secondary card slot as the secondary card includes:

s301, performing network detachment on the SIM card in the preset main card slot, and performing network detachment on the SIM card in the preset auxiliary card slot;

s302, setting the SIM card in the preset main card slot as a main card, and performing secondary network attachment on the SIM card in the preset main card slot; and setting the SIM card in the preset auxiliary card slot as an auxiliary card, and carrying out secondary network attachment on the SIM card in the preset auxiliary card slot.

In this embodiment, in step S301, network detachment is performed on the two SIM cards, and the mobile terminal resets the two SIM cards, so that all the functional modules of the mobile terminal return to the state before network attachment of the startup initialization.

In step S302, the secondary network attach refers to the SIM card re-attaching after detaching from the network, as compared with the network attach in step S2. The mobile terminal sets the SIM card in the preset main card slot as a main card and carries out the processes of starting up initialization and secondary network attachment again; and setting the SIM card in the preset auxiliary card slot as an auxiliary card, and performing the processes of starting up initialization and secondary network attachment again. For the one-way authenticated GSM network, the secondary network attachment process is as follows: the Mobile terminal sends a network access request to the network, the network replies a string of random character strings, the Mobile terminal receives and transmits the string of random character strings to the SIM card, the SIM card calculates according to a preset algorithm and returns a calculation result to the Mobile terminal, the Mobile terminal sends the calculation result, IMEI (International Mobile Equipment Identity) and ICCID back to the network, the network reads the ICCID and analyzes whether the number is a local number or not, and the network returns a legal message to finish the network attachment process. For the bidirectional authentication network, in the secondary network attachment process, not only the network needs to identify whether the user is legal, but also the user needs to identify whether the network is legal, and after the bidirectional authentication is legal, the network attachment process is completed, and specific steps are not described herein again.

The network registration process of cutting cards and re-attaching the cards to the two SIM cards is carried out orderly, so that the disorder of the mobile terminal and the network protocol is avoided, and the network start time of re-network registration after cutting the cards is effectively shortened.

Further, the types of the network include LTE, WCDMA, TDS, GSM, CDMA, EVDO.

In the embodiment of the present invention, the type of the network of the SIM card refers to an Access type used when an operator that a Mobile terminal accesses to the SIM card through the SIM card says that the network is provided, and includes various 2G, 3G, and 4G Access types such as lte (long Term Evolution), wcdma (wideband Code Division Multiple Access), TD-SCDMA (Time Division-synchronized Code Division Multiple Access), gsm (global System for Mobile communication), cdma (Code Division Multiple Access), EVDO (Evolution-Data Optimized), and the like.

According to the network registration method, after the position exchange of the SIM card in the preset main card slot and the SIM card in the preset auxiliary card slot is detected, the card cutting instruction is issued after the network attachment of the SIM card in the preset main card slot and the SIM card in the preset auxiliary card slot is finished, so that the conflict between the card cutting instruction and the network attachment of the SIM card can be avoided, the network-up delay caused by abnormal network attachment is avoided, the network registration is orderly carried out, and the speed of cutting and network-up is increased.
