The selected sharing soft SIM card mode can ensure that the probability of access conflict between the selected sharing soft SIM card and the sharing soft SIM card selected by other mobile terminals is very small, and even if the selected first sharing soft SIM card generates access conflict, the probability of access conflict generated by another sharing soft SIM card selected again is lower according to the selected mode, thereby ensuring that a plurality of mobile terminals select the same sharing soft SIM card to access a communication network at different time and reducing the operation cost. And the access conflict is the failure of the SIM card to access the communication network.

And S104, the mobile terminal accesses a communication network through the shared soft SIM card.

The information carried by the shared soft SIM card mainly includes an International Mobile Subscriber Identity (IMSI) and an authentication Key (KI) of the card, the mobile terminal accesses a local communication network through the IMSI and the KI of the shared soft SIM card, the communication network is a Public Land Mobile Network (PLMN), and the technical process of accessing the communication network is the prior art and is not described herein again.

S105, the mobile terminal sends a card distribution request to the card distribution server through the communication network; the card configuration request comprises the network type of the mobile terminal and the information of the local operator of the mobile terminal.

S106, the card distribution server side selects a special soft SIM card according to the priority of the special soft SIM card from the special soft SIM card group which enables the mobile terminal to access the local operator network and has the best signal according to the card distribution request, generates card distribution information and sends the card distribution information to the mobile terminal; and the card configuration information comprises the information of the selected special soft SIM card.

In this embodiment, the card configuration request includes, in addition to the network type of the mobile terminal and the information of the local operator, the device serial number and the system version information of the mobile terminal, and the card configuration server is mainly matched to the corresponding dedicated soft SIM card set according to the four types of reference information. The card configuration server is divided into different special soft SIM card groups in advance according to an operator to which the special soft SIM card belongs, a matched network type, an adapted user grade and a compatible mobile terminal system; the network standard comprises a 2G network (second generation mobile communication technology), a 3G network (third generation mobile communication technology) and a 4G network (third generation mobile communication technology); the user grade is associated with the equipment serial number of the mobile terminal, and the form of the user grade can be set according to specific situations. The card allocation server can match the best special soft SIM card group according to the card allocation request of the mobile terminal, then selects a special soft SIM card according to the priority rule of the special soft SIM card, binds the special soft SIM card with corresponding lease information, generates card allocation information and sends the card allocation information to the mobile terminal.

S107, the mobile terminal receives the card matching information returned by the card matching service terminal to obtain the special soft SIM card for the communication network.

S108, the mobile terminal logs off the connection between the shared soft SIM card and the communication network.

In this embodiment, the mobile terminal logs out the connection with the local communication network through the IMSI and KI of the shared soft SIM card, and this technical process of logging out the communication network is the prior art and is not described herein again. The mobile terminal receives the card matching information of the special soft SIM card returned by the card matching service end, and then cancels the connection of the shared soft SIM card and the communication network, so that the resource occupation of the shared soft SIM card can be reduced as much as possible, the cancelled shared soft SIM card can be used by other mobile terminals, and the occurrence of access conflicts is reduced.

And S109, the mobile terminal accesses a communication network through the special soft SIM card.

In the step S101, the shared card pool includes M shared soft SIM cards with different card numbers, the shared soft SIM cards with different card numbers are configured in a plurality of card groups, and the shared soft SIM cards in each card group are arranged in sequence, so that the shared soft SIM cards adjacent to the shared soft SIM card with the same card number in each card group are different from each other.

It should be noted that, the card provisioning service end divides a batch of shared soft SIM cards into shared card pools of corresponding network formats in advance according to the network format of each shared soft SIM card, further, divides the shared card pool of the same network format into a plurality of sub-shared card pools, and the shared soft SIM cards in each sub-shared card pool are not crossed with each other, so that the area where the mobile terminal conflicts in the process of selecting the shared soft SIM card to access the communication network can be reduced, and the card provisioning service end is also favorable for managing the shared soft SIM cards, thereby facilitating capacity expansion or contraction editing according to specific situations.

In this embodiment, for example, each sub-shared card pool includes M different card numbers sharing soft SIM cards, where the card numbers are mobile subscriber identification codes of each card, and the card groups are configured by selecting at most N different card numbers sharing soft SIM cards from the card group configuration modes in which the sharing soft SIM cards having the same card number are adjacent to the sharing soft SIM cards having the same card number in each card group, and configuring the sharing soft SIM cards into a plurality of sharing soft SIM card groups. Correspondingly, according to the card group configuration mode, the corresponding sharing soft SIM card group rule is configured to the mobile terminal, so that the mobile terminal selects the sharing soft SIM cards according to the sharing soft SIM card arrangement sequence of the sharing soft SIM card group, and when the mobile terminal accesses the communication network, the access conflict can be reduced.

In step S101, the shared soft SIM card group includes a plurality of shared soft SIM cards, and operator information and roaming country information supported by each shared soft SIM card;

It should be noted that the area accessing the communication network may be, but is not limited to, a national range of one of seven continents, a combined national range of seven continents, or all national ranges. In this embodiment, the card configuration server includes a plurality of shared card pools of the same network type as the mobile terminal, and thus the card configuration server selects a group of suitable shared soft SIM card sets from the idle shared card pools of the same network type to configure the shared soft SIM card sets to the mobile terminal.

In the present invention, the mobile terminal selects one shared soft SIM card for accessing a communication network from the shared soft SIM card set according to the shared soft SIM card set rule in three ways, as follows:

in a first implementation manner, the selecting, by the mobile terminal, a shared soft SIM card for accessing a communication network from the shared soft SIM card group according to the shared soft SIM card group rule specifically includes:

For example, when the mobile terminal accesses the communication network of the operator from the locally stored shared soft SIM card set, the selected shared soft SIM card a generates access conflict with other mobile terminals, and cannot be successfully accessed; at this time, the mobile terminal selects the next shared soft SIM card B again according to the arrangement sequence of the shared soft SIM cards in the card group; due to the combination of the card group configuration mode and the sharing soft SIM card group rule, the sharing soft SIM card selected again by other mobile terminals which generate access conflict with the mobile terminal can not be the same as the sharing soft SIM card B, so that the probability of generating access conflict again by the mobile terminal and other mobile terminals is greatly reduced in the process of accessing the communication network of an operator.

In a second embodiment, the shared soft SIM card group includes a plurality of shared soft SIM cards and operator information supported by each shared soft SIM card;

the mobile terminal acquires a local operator signal of the mobile terminal;

It should be noted that, when the access of the selected valid shared soft SIM card fails, another valid shared soft SIM card is selected again according to the embodiment to be used for accessing the communication network.

In this embodiment, the mobile subscriber identity is an IMSI. Since the device Serial Number (SN) of the mobile terminal is unique, when the same time T is accurate to the millisecond, the probability that the mobile terminal selects the shared soft SIM card in the shared soft SIM card group at the same time is very small, that is, the time when different mobile terminals select the shared soft SIM card is generally different, and the probability that the detected hash value calculated by combining the SN of different mobile terminals and the corresponding time T when the shared soft SIM card is selected is the same is smaller and generally different.

Correspondingly, as described above, in the mobile terminal including the same shared soft SIM card, the probability that the shared soft SIM card of the mobile terminal is the same as the reference hash value calculated by combining the shared soft SIM card with the time T is very small, and for different detected hash values, the probability that the shared soft SIM card of the mobile terminal is the same in position in the sequence of the offset values corresponding to the shared soft SIM card group is lower, and in addition, the rule of the sequence selection is the same for all mobile terminals, for example, for all mobile terminals, an effective shared soft SIM card corresponding to the reference hash value closest to the detected hash value is selected; or, for all mobile terminals, selecting an effective shared soft SIM card corresponding to the reference hash value farthest from the detected hash value, thereby avoiding selecting the same shared soft SIM card for different mobile terminals at the same time to a greater extent.

On the other hand, before the shared soft SIM card is selected by the hash algorithm, the mobile terminal selects all effective shared soft SIM cards that can be used at the current time from the shared soft SIM card group, and when the implementation is specific, for example, the mobile terminal selects the shared soft SIM card a to access the communication network, then from the time of selection, a certain time length T1 is added, that is, the next available time of the shared soft SIM card a; or, the mobile terminal selects the shared soft SIM card a to access the communication network successfully, and then adds a certain time length T2 from the moment of successful access, which is the available time of the shared soft SIM card; the mobile terminal selects the shared soft SIM card A to fail to access the communication network, and then a certain time length T3 is added from the moment of the access failure, namely the moment when the shared soft SIM card A is available next time. In this embodiment, the record of the valid available time may indicate the next available time of the shared soft SIM card, so as to reduce the probability of failure of accessing the selected shared soft SIM card to the communication network; in addition, the selected effective shared soft SIM card can enable the mobile terminal to access the communication network of the local operator.

A third implementation manner is implemented on the basis of the second implementation manner, and when the access of the selected effective shared soft SIM card fails, the mobile terminal sequentially selects and selects the next effective shared soft SIM card for accessing the communication network according to the arrangement sequence of the effective shared soft SIM cards selected from the shared soft SIM card group.

In this embodiment, according to the second embodiment, the mobile terminal selects an effective shared soft SIM card from the locally configured shared soft SIM card group for the first time, and when the access fails to access the communication network, selects another effective shared soft SIM card subsequently, and selects the effective shared soft SIM card according to this embodiment. Because the shared soft SIM cards in each shared soft SIM card group are arranged in sequence, and the shared soft SIM cards adjacent to the shared soft SIM card with the same card number in each card group are configured in different card group configurations, the probability of access failure caused by re-selecting the shared soft SIM card is basically zero after the first access failure, and therefore, the implementation method can further reduce the generation of access conflict.

Further, in step S104, after the mobile terminal accesses the communication network through the shared soft SIM card, the method further includes:

It should be noted that the first execution log records information of all selected shared soft SIM card access communication network processes, and is used to upload the information to the card configuration server, and the card configuration server performs data analysis on the use conditions of the shared soft SIM cards in different shared soft SIM card groups, and adjusts the shared soft SIM card groups.

Further, in step S109, after the mobile terminal accesses the communication network through the dedicated soft SIM card, the method further includes:

It should be noted that the second execution log records information of all acquired processes of accessing the dedicated soft SIM card to the communication network, and is used to upload the information to the card configuration server, and the card configuration server may perform data analysis on the usage of the dedicated soft SIM card through the second execution log, and adjust the allocation of the dedicated soft SIM card.

In this embodiment, the failure of the access result of the shared soft SIM card includes two cases: the shared soft SIM card fails to be directly accessed into the communication network, and the access failure is caused by the problem of registration conflict after the shared soft SIM card is successfully accessed into the communication network. And when the access result of the special soft SIM card is failure, reselecting another shared soft SIM card to access the network, applying for another special soft SIM card, and simultaneously uploading the information of the special soft SIM card with failed access to the card distribution service terminal so as to record the access failure of the card in the communication network of the mobile terminal and adjust the distribution of the special soft SIM card. In this embodiment, the access conflict refers to an access result failure.

Further, after step S104 or step S109, that is, after the mobile terminal accesses the communication network, the method further includes:

if so, recording that the mobile terminal is in a network disconnection state;

if not, recording that the mobile terminal is in a network connection state.

In this embodiment, there are two situations for the heartbeat signal sent by the mobile terminal, one is that after the mobile terminal successfully accesses the communication network through the selected shared soft SIM card, the heartbeat signal is sent to indicate that the mobile terminal selecting the shared soft SIM card is in a network connection state; and the other method is that after the mobile terminal successfully accesses the communication network through the acquired special soft SIM card, a heartbeat signal is sent to indicate that the mobile terminal acquiring the special soft SIM card is in a network connection state. For example, the heartbeat signal carries the device serial number of the mobile terminal and the information of the shared soft SIM card or the information of the dedicated soft SIM card of the mobile terminal in the network connection state, and the card configuration server may further record the network connection state of the mobile terminal.

The card configuration server determines whether the heartbeat signal is overtime, and may be implemented specifically, after the mobile terminal accesses the communication network through the soft SIM card a, the card configuration server determines that the communication network accessed by the soft SIM card a selected by the mobile terminal is in a network disconnection state if the heartbeat signal or any other data is not sent to the card configuration server within a specified X seconds, and records the communication network state of the mobile terminal. Wherein the soft SIM card a may be, but is not limited to, a shared soft SIM card or a dedicated soft SIM card.

In the present invention, after the card provisioning server receives the first execution log uploaded by the mobile terminal, there are two embodiments of adjusting the shared soft SIM card group by the card provisioning server, specifically:

In this embodiment, the access failure is an access conflict. For example, if the shared soft SIM card a reaches the number of access conflicts N times within the time period T, and the card provisioning service terminal determines that the shared soft SIM card a has a problem during access, the shared soft SIM card is replaced with a new shared soft SIM card in the shared card pool and the shared soft SIM card group including the shared soft SIM card, so as to configure the adjusted shared soft SIM card group to the mobile terminal corresponding to the shared soft SIM card group before adjustment.

In this embodiment, according to the information of the first execution log uploaded by each mobile terminal, the number of cards with access conflicts in the shared soft SIM card set configured for each mobile terminal may be counted, when the number of cards is greater than a preset value, another shared soft SIM card set may be selected from the corresponding card pool to replace the shared soft SIM card set, and the shared soft SIM card set is marked as unallocated, and then the selected new shared soft SIM card set is configured for the mobile terminal, so as to update the shared soft SIM card set of the mobile terminal. When the number of the cards is larger than another preset value, adding a certain number of shared soft SIM cards in a shared card pool where the shared soft SIM card group is located, reconfiguring the shared soft SIM card group in the shared card pool to increase the number of the shared soft SIM card groups in the shared card pool to reduce access conflicts, or increasing the number of the cards in the shared soft SIM card group in the shared card pool to reduce access conflicts, and configuring the adjusted new shared soft SIM card group to the mobile terminal corresponding to the shared soft SIM card group before adjustment to update the shared soft SIM card group of the mobile terminal.

In this embodiment, for example, when the dedicated soft SIM card B reaches the number of access conflicts N times within the time period T, and the card provisioning server determines that the access of the shared soft SIM card B is problematic, the shared soft SIM card B is replaced with a new shared soft SIM card C in the shared soft SIM card group including the dedicated soft SIM card B, or the shared soft SIM card B is marked as unallocated, and the allocation of the shared soft SIM card is adjusted.

It should be noted that the update information is used for providing the corresponding mobile terminal with an update of the shared soft SIM card group, and the transmission of the update information may be through a communication network accessed by the shared soft SIM card or through a communication network accessed by the dedicated soft SIM card, but preferably, the update information is transmitted in the communication network accessed by the dedicated soft SIM card to reduce the usage time of the shared soft SIM card, which may further reduce the generation of access conflicts of the shared soft SIM card; moreover, the data transmission effect of the communication network accessed by the special soft SIM card is generally better than that of the communication network accessed by the shared soft SIM card, and the updating efficiency can be further improved.

On the other hand, the update may be an active update or a passive update of the mobile terminal. And actively updating, namely, the mobile terminal actively sends version information of a shared soft SIM card group to the card matching server so that the card matching server can compare the version information, if the version of the shared soft SIM card group is different from the version of the shared soft SIM card group stored by the card matching server, the card matching server generates update information, sends the update information to the mobile terminal, then the mobile terminal performs corresponding update, and if the version is the latest version, only information prompting that the update is not needed needs to be sent to the mobile terminal. And passive updating is that the card distribution server generates updating information according to the latest shared soft SIM card group, and as long as the mobile terminal corresponding to the shared soft SIM card group is in a network connection state, the mobile terminal passively receives the updating information sent by the card distribution server and then performs corresponding updating. The updating includes adding, subtracting, or replacing shared soft SIM cards to, or even replacing the entire set of shared soft SIM cards. Of course, the update information may also include adjustment information for the rules of the shared soft SIM card group.

In the present invention, there are various ways for the mobile terminal or the card-equipped service end to log off the dedicated soft SIM card, and the following examples respectively describe the method for logging off the dedicated soft SIM card in detail.

In one embodiment, the card provisioning information further includes lease information for the dedicated soft SIM card;

In this embodiment, when the mobile terminal determines that the lease of the mobile terminal expires, the mobile terminal actively cancels the connection between the dedicated soft SIM card and the communication network.

In another embodiment, on the basis of the above one embodiment, the method for implementing a communication connection of a mobile terminal further includes:

the mobile terminal receives the logout information;

In this embodiment, on one hand, when the mobile terminal determines that the lease of the mobile terminal expires, the mobile terminal actively cancels the connection between the dedicated soft SIM card and the communication network, and on the other hand, when the card provisioning server determines that the lease of the mobile terminal expires, the card provisioning server generates cancellation information and sends the cancellation information to the mobile terminal, so as to prompt the mobile terminal to cancel the connection between the dedicated soft SIM card and the communication network; the card-matching service end marks that the special soft SIM card can be allocated, namely, the special soft SIM card can be allocated to other mobile terminals for accessing the communication network, and of course, the mobile terminal using the special soft SIM card stops using the special soft SIM card at the moment.

Further, based on the above embodiment, the method for implementing communication connection of a mobile terminal further includes:

In this embodiment, when it is determined that the mobile terminal corresponding to the allocated dedicated soft SIM card is in the network disconnection state for a long time, the dedicated soft SIM card may be re-allocated to another mobile terminal, and certainly, when the mobile terminal using the dedicated soft SIM card is ready to access the communication network again, another dedicated soft SIM card needs to be re-applied.

In this embodiment, the card configuration server selects the dedicated soft SIM card according to the priority of the dedicated soft SIM card in the dedicated soft SIM card group. When the card distribution service end marks a special soft SIM card as distributable, the recovery of the special soft SIM card can be realized, the selected priority of the special soft SIM card is reduced, the mobile terminal using the special soft SIM card can be given enough time to logout the special soft SIM card and the communication network, and other mobile terminals are distributed when the special soft SIM card is not logout and the communication network, so as to avoid access conflict.

The method for realizing the communication connection of the mobile terminal provided by the embodiment of the invention selects a sharing card from a sharing soft SIM card group configured for the mobile terminal by a card configuration service terminal stored in the mobile terminal, accesses a communication network, then connects with the card configuration service terminal, applies for and acquires a special soft SIM card, cancels the communication connection of the sharing soft SIM card, releases the resource of the sharing soft SIM card, and then adopts the special soft SIM card to access the network, thereby realizing the communication connection of the mobile terminal. On one hand, a mode of sharing the soft SIM card is adopted, so that a small number of cards can support a large number of mobile terminals to access a communication network, and the problem of high operation cost is solved; on the other hand, the card distribution service terminal distributes a special soft SIM card according to the card distribution request provided by the mobile terminal, and the special soft SIM card can enable the mobile terminal to be accessed to a local operator network and has the best signal, thereby realizing the dynamic selection of the operator network for the user and improving the service quality.
