And the bicycles, especially the shared bicycle, are widely distributed nationwide, the user use degree is high, and the popularization of the scheme in the embodiment nationwide is facilitated. The network registration method of the embodiment comprises the following steps:

The communication module of this embodiment may be a wireless communication module or a wired communication module, the wired communication module is provided with a data line interface for performing data interaction with a data interface (generally, a power interface) on the user terminal through a data line, and the data line interface of the wired communication module may be a USB interface, so that the wired data interaction between the wired communication module and the user terminal can be completed by using a power line of the user terminal. Further, in order to avoid the situation that the user cannot use the wired communication module without carrying the data line, in this embodiment, the wired communication module may be provided with a data line, and in order to adapt to more user terminal models, the data line may be provided with a plurality of types of interfaces, such as a Type-C interface, an apple Lightning interface, and the like. For the wireless communication module, it may be a bluetooth module, a WiFi module, an NFC module, an external transmission module, and other wireless communication modules, but considering that data downloaded or sent by the user through the second SIM card needs to pass through the wireless communication module and the network assisted registration module, the faster the data transmission, the better the user experience, so generally, the wireless communication module is preferably a module with faster data transmission, such as a WiFi module or a high-speed bluetooth module, and of course, the wireless communication module of this embodiment may be other types of modules.

The second SIM card in this embodiment may be a card in any one of two card slots of the dual-card terminal, and the second SIM card may be a "standard card" (SIMCARD), "small card" (Micro SIM), or "mini card" (Nano SIM). Wherein the SIM big card: the size of the standard card is 25mm multiplied by 15mm, and the standard card is a card used by most mobile phones at present; micro SIM card-size is 12 x 15mm, is the size of the chip on the standard card; the Nano SIM miniature card is currently the smallest, only 12mm x9mm in size. In this embodiment, the size of the SIM card is not limited, and the operator to which the SIM card belongs is not limited at all, for example, in China, the operator to which the second SIM card belongs may be any one of mobile, internet and telecommunication. In view of the popularization of the existing 4G network, the second SIM card is generally a 4G card, and of course, with the continuous development of network systems, the second SIM card may also be a 5G card, and so on. The user terminal of the present embodiment refers to the structure and the related description of the mobile terminal shown in fig. 1.

In this embodiment, when the target bicycle is a sharing bicycle, the establishing of the connection between the target bicycle and the user terminal includes: the intelligent coded lock on the shared bicycle is connected with the user terminal, and the authentication of the user terminal is successful (wherein the successful authentication of the user terminal can include the successful unlocking of the intelligent coded lock). Therefore, the SIM card registration of an illegal user by using the communication module and the network auxiliary registration module can be avoided. Furthermore, the power supply circuit of the communication module and the network auxiliary registration module can be controlled, and the communication module and the network auxiliary registration module are controlled to be powered on only after the identity authentication of the user terminal is successful.

S302, a network auxiliary registration module on the target bicycle acquires registration information of the second SIM card received by the communication module;

the network auxiliary registration module is in circuit connection with the communication module, and the network auxiliary registration module is used for registering a second SIM card to a network of a corresponding operator through information interaction between the communication module and the second SIM card on the user terminal. The network assisted registration module includes a modem, which can convert digital signals into analog signals and convert analog signals into digital signals. In this embodiment, the network assisted registration module is connected to the communication module, and the acquiring, by the network assisted registration module, the registration information of the second SIM card received by the communication module includes: the communication module sends the registration information of the second SIM card to the network auxiliary registration module through the connection with the network auxiliary registration module, and the network auxiliary registration module receives the registration information of the second SIM card. The registration information of the second SIM card is information required for registering the second SIM card to a corresponding operator network, and it is expected that the registration information carries identification information of the SIM card, such as a phone number of the SIM card, and the like.

At present, an intelligent combination lock is generally arranged on a shared bicycle, the network registration module of this embodiment may be integrated in the intelligent combination lock, or the network registration module of this embodiment may be arranged at other positions of the shared bicycle, which is not limited in this embodiment.

At present, a power supply device (generally, a solar panel) is generally integrated on a bicycle using an intelligent coded lock, and in order to reduce a modification part of a shared bicycle, the power supply device may also be used as a power supply device of a network registration module in an example of the embodiment.

S303, the network auxiliary registration module identifies an operator network to which the second SIM card is to be registered according to the registration information, and registers the second SIM card in the operator network according to the registration information;

in this embodiment, the network assisted registration module may identify an operator to which the SIM card belongs according to registration information, such as a phone number of the SIM card, and send the registration information to a corresponding operator network. It can be understood that, during registration, a network in which the SIM card can be registered is affected by not only an operator to which the SIM card belongs but also a network standard supported by the network assisted registration module, and the network assisted registration module in this embodiment may support all standards of domestic operators in one example. In consideration of the development of the current network standard, the network assisted registration module of this embodiment may also perform software or hardware update, so as to support a network standard faster than 4G, such as 5G, and so on. Further, the network systems supported by the network assisted registration module of this embodiment include, but are not limited to, the network systems after 2G, 3G, 4G, and 4G.

It can be understood that, when the network assisted registration module identifies the operator network to which the second SIM card is to be registered, assuming that the identified operator network is mobile, if the currently mobile 4G network has poor signal, the last registration may be a mobile 3G or 2G network. In the process that the user terminal uses the network auxiliary module to surf the internet, when the mobile 4G network around the user terminal is detected to have better signals, the network of the second SIM card can be switched to the 4G network with better signals, and the switching process can be realized through the communication module and the network auxiliary registration module of the target bicycle.

S304, the network auxiliary registration module acquires the successful registration information returned by the operator network, and the successful registration information is sent to the second SIM card of the user terminal through the communication module to complete the operator network registration of the second SIM card.

After the registration information is sent out, the network auxiliary registration module receives the information of successful registration of the second SIM card returned by the operator network, and sends the information of successful registration to the second SIM card, so that the registration of the second SIM card is completed. In this embodiment, in the method for registering the second SIM card in the operator, the data exchanged between the second SIM card and the operator network is the same as the data exchanged when the SIM cards on other terminals register the operator network through the terminal, and the difference between the two methods is that in this embodiment, the data exchanged with the second SIM card needs to be transmitted to the network auxiliary registration module on the target bicycle through the communication module of the user terminal itself and the communication module on the target bicycle, and then the network auxiliary registration module sends the registration information to the operator network.

In the network registration method of the embodiment, the communication module and the network registration auxiliary module are arranged on the bicycle, so that the connection between the communication module on the target bicycle and the user terminal can be established after the connection between the target bicycle and the user terminal is established, and the communication module receives the registration information of the second SIM card sent by the user terminal; the network auxiliary registration module on the target bicycle acquires the registration information of the second SIM card received by the communication module; the network auxiliary registration module identifies an operator network to which the second SIM card is to be registered according to the registration information, and registers the second SIM card to the operator network according to the registration information; the network auxiliary registration module acquires the successful registration information returned by the operator network, and sends the successful registration information to the second SIM card of the user terminal through the communication module to complete the operator network registration of the second SIM card. Therefore, the dual-card terminal can simultaneously use two networks of the two SIM cards to send and download data at the same time, so that the bandwidth of the user terminal is improved, and the user experience is improved.
