Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying 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 obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

In order to solve technical problems in the prior art, a first aspect of the embodiments of the present application shows a dual-channel network connection system, and specifically, please refer to fig. 1.

The system comprises: cloud, terminal. Wherein the terminal is provided with: the SIM virtual machine comprises a main control module, a secondary card channel module and an SIM virtual machine; the master control module comprises: the system comprises a selection module, a VSIM card acquisition module and a state analysis module; the main control module stores a SIM card list.

Wherein, the SIM card list includes: an emergency card, a group card, and a channel card.

The emergency card and the grouping card are pre-stored in the SIM card list, and the channel card can be pre-stored in the SIM card list or applied from the cloud in the application process.

(1) Specifically, a group of emergency cards are configured for the terminal during terminal production, and the emergency cards are written into the SIM card list. The emergency cards are a group of soft cards which do not distinguish the use countries, 2-3 emergency cards are randomly selected as a group according to the proportion that each emergency card supports 2000 terminals, and each emergency card can be used in a plurality of terminals during production and writing of the terminal.

The distribution mode of the emergency cards shown in the embodiment of the application avoids the problem that a large number of emergency cards are in an idle state, and on the other hand, the technical scheme shown in the embodiment of the application can ensure that each terminal has an emergency card which is dedicated to the terminal to serve at any moment.

Specifically, all production terminals are started up by less than 5% at the same time and are distributed in more than one hundred countries around the world for use, and if one emergency card is configured for each equipment during production, most emergency cards are actually in an idle state. By adopting the allocation mode that each emergency card supports 2000 terminals, the problem that a large number of emergency cards are in an idle state is avoided.

Furthermore, each terminal corresponds to 2-3 emergency cards, and for any two terminals, at most one common emergency card exists. For example, when the terminal 1 applies for the emergency card 1 to connect to the network, it happens that the emergency card 1 provides service for the terminal 2, and in this case, the emergency card 1 is released from the SIM card list corresponding to the terminal 2, and at this time, the terminal 1 and the terminal 2 simultaneously apply for other emergency card connection networks in their respective SIM card lists, because the terminal 1 and the terminal 2 share at most one emergency card, and when the terminal 1 and the terminal 2 select the emergency card again, the terminal 1 and the terminal 2 select the emergency card that must not be shared, it is ensured that each terminal has an emergency card dedicated to the terminal at any time to serve the emergency card.

(2) When the terminal leaves factory for operation, a group of grouping cards are configured for the terminal, and relevant data of the grouping cards are written into an SIM card list. Packet cards are soft cards used in several specific countries, while in one country they can be used by multiple operators. In the practical application process, the grouping cards can be grouped in advance according to different countries supported by the grouping cards.

(3) In the using process of the terminal, a channel card is configured for the terminal, and the relevant data of the channel card is written into the SIM card list. The channel card is a soft card that indicates a country of use.

In the using process of the terminal, the terminal applies for a channel card supporting the location of the terminal from the cloud, the channel card is started in the auxiliary channel, a first communication channel is established, and the first communication channel is always kept in an online state. When the terminal is powered off, the channel card is kept for a period of time after the terminal is powered off, the terminal preferably uses the channel card to establish a first communication channel during the period of time, and if the terminal is not powered on after the retention time is exceeded, the channel card is released for other terminals to use.

the auxiliary card channel module is used for establishing a first communication channel by using the target SIM card;

the VSIM card acquisition module is used for accessing the cloud by utilizing the first communication channel and acquiring the VSIM shared by the cloud;

and the SIM card simulator is used for establishing a second communication channel by utilizing the VSIM.

And the state analysis module is used for acquiring the current state of the terminal in real time and sending the current state to the selection module.

The current state may be current location information of the terminal, or a network signal, or a network connectivity message, or a combination thereof.

Specifically, after receiving the current state of the terminal, the state analysis module analyzes the current state of the terminal to obtain a series of analysis information such as network connection information of the terminal, the location of the terminal, and an operator of a strongest network signal corresponding to the location of the terminal. And the state analysis module sends the analysis information to the selection module, and the selection module selects the most appropriate target SIM card for the terminal according to the analysis information and a preset priority rule.

Wherein the preset priority rule is as follows: the priority of the channel card is greater than that of the grouping card and greater than that of the emergency card;

specifically, a SIM card list corresponding to one terminal includes: a channel card, a plurality of packet cards, and a plurality of emergency cards. There is a case where the shutdown time of the terminal is greater than the preset shutdown time, and at this time, the channel card is released, where the SIM card list includes: a plurality of group cards, and, a plurality of panic cards.

In the using process of the terminal, the main control module applies for a channel card from the cloud, the auxiliary card channel module utilizes the channel card to establish a first communication channel for the auxiliary channel, and the first communication channel is always kept in a communicated state. There are two cases where the first communication path is disconnected: one is the shutdown of the terminal; one is that the location of the terminal is changed, so that the channel card does not support the network access service at the current location of the terminal.

For the shutdown condition, the channel card is reserved in the SIM card list for a period of time, during which the channel card is preferably used by the auxiliary card channel module, and if the channel card is not started up for more than the reserved time, the channel card is released for other terminals to use.

After the terminal is started, whether a channel card is stored in the SIM card list or not is judged, whether the channel card is effective or not is judged, and if the terminal does not have the channel card or the channel card is invalid, the terminal selects a packet card to access the network.

If the SIM card list stores the channel card, firstly, the network searching is not carried out, and the auxiliary card channel module directly accesses the network by the operator which has been accessed by the channel card last time. If the access is not available, the terminal may change countries, the secondary channel is started to search the network, the network searching result of the country supported by the channel card and the secondary channel is compared, and if the searched country supports the existing channel card, the channel card is continuously used for accessing the network. If the channel card can not be successfully accessed to the network, the channel card is proved to be invalid, and the target SIM card is selected from the group cards according to the preset priority rule.

The process of selecting the target SIM card in the grouped cards comprises the following steps:

the service attribute corresponding to the packet card is recorded in each SIM card list. The service attributes comprise roaming service areas, domestic service areas, home location information, charging strategies, internet access configuration and the like. Wherein, the charging strategy includes the flow rate charge corresponding to the SIM card, and the flow rate charge includes: the charging package quota, the charging rate, the working time and the like. The technical scheme shown in the embodiment of the application makes normalization statistics on corresponding service attributes, for example, converts the service attributes of each packet card into the cost generated by each megaflow.

The selection module analyzes the position information of the terminal according to the current state reported by the state analysis module in real time to obtain the { country code }. The selection module then obtains a dynamic grouping card list according to the roaming service area of the grouping card in the SIM card list, wherein the grouping card list records the area served by each grouping card. The selection module searches out an alternative grouping card matched with the geographical position of the terminal from the dynamic grouping card list to generate an alternative grouping card set; and the service attribute normalized by each alternative grouping card is stored in the alternative grouping card set.

And the selecting module is used for screening the alternative grouping cards which generate the optimal service attribute from the alternative grouping card set as the SIM cards to be accessed.

The optimal service attribute may be calculated as follows: the technical scheme shown in the embodiment of the application performs normalization statistics on corresponding service attributes, for example, the flow charge of each packet card is converted into the charge generated by each megaflow. And then arranging the alternative packet cards in the alternative packet card set according to a sequence from high to low of the traffic tariff.

The optimal service attribute may be calculated as follows: we can classify the data of the alternative packet card set into three types, static priority, rate priority and performance priority. The selection module can select different priority strategies as distribution strategies according to different service requirements. The static priority is to carry out screening and sorting according to corresponding conditions specified manually, and a series of available SIM card data lists are obtained according to the matching degree; the rates are preferably sorted according to the charging rates of the SIM card lists to obtain a series of available SIM card data lists, wherein the rates are low and the priority is high; and the performance is preferentially sorted according to the network performance data of the SIM card list to obtain a series of available SIM card data lists, and the SIM card data lists are high in performance and priority.

And the selection module screens out the alternative packet card generating the optimal service attribute as a packet card to be accessed, and the packet card to be accessed is utilized to access the network.

And if a feedback message of network communication is received within a preset time, determining that the packet card to be accessed is a target SIM card. The secondary channel module establishes a first communication channel by using the target SIM card; the main control module accesses the cloud end by using the first communication channel to obtain the VSIM shared by the cloud end; the first communication path provides a communication link for loading and authentication of the VSIM, and the SIM card simulator establishes a second communication path by using the VSIM. After the second communication channel of the terminal is successfully accessed to the network, the used target SIM card (packet card) needs to be released for other terminals to use, so as to prevent card collision. At the moment, the terminal applies for a channel card supporting the location of the terminal from the cloud, and establishes a first communication channel when the channel card supporting the location of the terminal is started, wherein the first communication channel is always kept in an online state.

If the feedback message of network communication is not received within the preset time, deleting the packet card to be accessed, and screening out the alternative packet card generating the optimal service attribute as the packet card to be accessed again; accessing the network by using the packet card to be accessed; and if the alternative packet cards in the alternative packet card set are not successfully accessed to the network, the emergency card is used for accessing the network.

Specifically, after the candidate packet cards access the network, if a feedback message of network communication is not received within a preset time, counting the number of the candidate packet cards in the candidate packet card set after the candidate packet cards generating the optimal service attribute are removed from the candidate packet card set, and judging whether the number is greater than zero; if the number is larger than zero, the packet cards which are not tried to be connected are proved to be in the alternative packet card set, at this time, the alternative packet card set is traversed, the alternative packet cards which generate the optimal service attribute are screened out to be used as the packet cards to be accessed, and the steps are carried out in sequence until the number of the alternative packet cards in the alternative packet card set is zero or one of the alternative packet cards is successfully connected with the network.

And under the condition that the number of the alternative grouping cards in the alternative grouping card set is zero, calling any emergency card in the SIM card list as a target SIM card. The auxiliary card channel module utilizes a first communication path established by the emergency card. And the main control module accesses the cloud end by using the first communication channel to acquire the VSIM shared by the cloud end. The SIM card simulator establishes a second communication path using the VSIM. After the second communication channel of the terminal is successfully accessed to the network, the used target SIM card (emergency card) needs to be released for other terminals to use, so that card conflict is prevented. At the moment, the terminal applies for a channel card supporting the location of the terminal from the cloud, and establishes a first communication channel when the channel card supporting the location of the terminal is started, wherein the first communication channel is always kept in an online state.

Optionally, the terminal further includes an RJ45 interface communication module and an RJ45 interface communication module, and is configured to establish a service channel between the main control module and the cloud for accessing the internet through a network cable;

in practical application, the embodiment of the invention can also support a network roaming solution based on a network cable, so that Wi-Fi access can be realized by using an RJ45 interface communication module of a network roaming terminal under the condition that the location has the network cable. That is to say, the embodiment of the present invention provides a Wi-Fi provision scheme implemented based on multiple access network modes. Can be selected and used according to specific situations. Preferably, when the network cable is used, the 2G or 3G or 4G or 5G network can be shut down, so that the power consumption is further reduced, and the utilization of network channels is further saved.

It can be seen that in the technical scheme shown in the embodiment of the present application, a first communication path is established by using a target SIM card in a manner of selecting the target SIM card from a SIM card list, the first communication path is used for applying for VSIM for a main channel, and a communication link is provided for loading and authentication of VSIM, the first communication path is always kept in an online state, and an efficient and reliable communication link is always provided for the main channel, so that a user does not need to spend time in a local business hall to purchase a SIM card supporting local use, and can apply for VSIM for a terminal through the first communication path, thereby avoiding waste of time and improving communication efficiency.

Referring to fig. 2, a second aspect of the embodiment of the present application illustrates a dual-channel network connection method, including:

the SIM card list corresponding to the terminal comprises: an emergency card, a group card, and a channel card.

When the terminal leaves factory for operation, a group of grouping cards are configured for the terminal, and relevant data of the grouping cards are written into an SIM card list. In the using process of the terminal, a channel card is configured for the terminal, and the relevant data of the channel card is written into the SIM card list.

The terminal selects a target SIM card from the SIM card list, wherein the selection process of the target SIM card is as follows:

the terminal detects whether a channel card exists in the SIM card list and judges whether the channel card is effective or not; and if the channel card exists and is valid, determining that the channel card is the target SIM card. And if the channel card does not exist in the SIM card list or the channel card is invalid, selecting a target SIM card from the SIM card list according to a preset priority rule and the communication state of the terminal.

Specifically, the SIM card list usually includes a channel card, a group card, and an emergency card, and the terminal establishes a first communication path by using the channel card, and the first communication path is always kept in a connected state. The first communication path is disconnected under two conditions, namely, the terminal is powered off; one is that the location of the terminal is changed, and the channel card in the current location of the terminal does not support the network access service. In the case of power-off, the channel card is retained in the terminal for a period of time during which the terminal preferably uses the channel card, and if the terminal is not powered on for a period of time exceeding the retention time, the channel card is released for use by other terminals.

Under the condition that the terminal is powered on again, whether the channel card is stored in the SIM card list or not and whether the channel card is valid or not is judged, and if the terminal does not have the channel card or the channel card is invalid, the terminal selects a packet card to access the network.

The method for judging whether the channel card is valid is as follows: an operator accessed last time by the channel card is used for accessing a network; if a feedback message of network connection is received within a preset time, the channel card is valid; if a feedback message of network connection is not received within a preset time, judging whether the channel card supports the use of the location of the terminal; if so, the channel card is valid.

Specifically, the terminal accesses the network by using the operator to which the channel card has been accessed last time, if the terminal successfully connects the network, the terminal will get a feedback message of network connection within a preset time, in which case the terminal is proved to be valid, the terminal determines that the channel card is the target SIM card, if the terminal accesses the network by using the operator to which the channel card has been accessed last time, the terminal receives the feedback message of network connection within a preset time period, and at this time, the terminal may have changed countries, and starts the secondary channel to search for the network. And comparing the network searching results of the country supported by the channel card and the auxiliary channel, and if the searched country supports the existing channel card, continuing to use the channel card as a target DIM card. If the channel card can not be successfully accessed to the network, the channel card is proved to be invalid, and the target SIM card is selected from the group cards according to the preset priority rule.

The process of selecting the target SIM card in the group cards comprises the following steps: the terminal selects the grouping cards supported by the terminal from the SIM card list as alternative grouping cards to generate an alternative grouping card set; calling a service attribute corresponding to the location of the terminal of each alternative packet card in the alternative packet card set, and screening out the alternative packet card generating the optimal service attribute as a packet card to be accessed; accessing the network by using the packet card to be accessed; and if a feedback message of network communication is received within a preset time, determining that the packet card to be accessed is a target SIM card.

Specifically, the method comprises the following steps: the service attribute corresponding to the packet card is recorded in each SIM card list. The service attributes comprise roaming service areas, domestic service areas, home location information, charging strategies, internet access configuration and the like. The charging policy includes a traffic tariff corresponding to the SIM card, where the traffic tariff includes: the limit of the fee-charging package, the fee-charging rate, the working time and the like. The technical scheme shown in the embodiment of the application makes normalization statistics on corresponding service attributes, for example, the flow charge of each packet card is converted into the charge generated by each megaflow.

The terminal analyzes the position information of the terminal according to the current state to obtain { country code }, and obtains a dynamic grouping card list according to the roaming service area of the grouping card in the SIM card list, wherein the grouping card list records the area served by each grouping card. Searching an alternative grouping card matched with the geographical position of the terminal in the dynamic grouping card list to generate an alternative grouping card set; and the service attribute of each alternative grouping card in the alternative grouping card set after normalization. And screening the alternative packet card generating the optimal service attribute as the SIM card to be accessed.

The terminal accesses the network by using the packet card to be accessed; and if a feedback message of network communication is received within a preset time, determining that the packet card to be accessed is a target SIM card. Trying to access the network in the alternative packet cards, if a feedback message of network communication is not received within a preset time, counting the number of the alternative packet cards in the alternative packet card set after the alternative packet cards which generate the optimal service attribute are removed from the alternative packet card set, and judging whether the number is greater than zero or not; if the number is larger than zero, the packet cards which are not tried to be connected are proved to be in the alternative packet card set, at this time, the alternative packet card set is traversed, the alternative packet cards which generate the optimal service attribute are screened out to be used as the packet cards to be accessed, and the steps are carried out in sequence until the number of the alternative packet cards in the alternative packet card set is zero or one of the alternative packet cards is successfully connected with the network.

Calling any emergency card of the SIM card list as an emergency card to be accessed under the condition that the number of the alternative group cards in the alternative group card set is zero; and if receiving the occupied feedback information of the first emergency card to be accessed, releasing the emergency card to be accessed, and calling any emergency card in the SIM card list as a target SIM card.
