In this embodiment, the customer premise equipment may access a cellular network (also referred to as a mobile network) through the radio frequency system, and then convert the cellular network into a WiFi signal for the external equipment to access the network.
As shown in fig. 2, fig. 2 is a first structural block diagram of an electronic device 100 according to an embodiment of the present disclosure, where the electronic device 100 includes an embedded subscriber identity module chip 101, a modem chip 102, an identity card connection unit 103, and a switching unit 104, where the identity card connection unit 103 is configured to establish an electrical connection with a subscriber identity module card 105, and the embedded subscriber identity module chip 101, the modem chip 102, and the identity card connection unit 103 are all connected with the switching unit 104.
The switching unit 104 is configured to switch between the modem chip 102 and the embedded subscriber identity module 101 or between the modem chip 102 and the subscriber identity module 105 according to a connection status corresponding to whether the identification card connecting unit 103 is electrically connected to the subscriber identity module 105.
During the start-up process of the modem chip 102, the switching unit 104 is used for connecting the modem chip 102 and the embedded subscriber identity module 101 when the identification card connecting unit 103 is not electrically connected to the subscriber identity module 105, and connecting the modem chip 102 and the subscriber identity module 105 when the identification card connecting unit 103 is electrically connected to the subscriber identity module 105.
The embedded Subscriber Identity chip 101 is also called an eSIM card (embedded Subscriber Identity Module), that is, a conventional Subscriber Identity card is integrated on a terminal device chip, rather than being added to the device as a separate removable component, and a user does not need to insert a physical SIM card (Subscriber Identity Module).
The identification card connection unit 103 is used to establish an electrical connection with the subscriber identification card 105 physically.
In at least one embodiment, the SIM card 105 is a plug-in SIM card that can be plugged into or unplugged from the SIM card connecting unit 103.
The switching unit 104 can switch the connection state according to whether the identification card connecting unit 103 is electrically connected to the subscriber identification card 105, so as to connect the modem chip 102 and the embedded subscriber identification chip 101 or connect the modem chip 102 and the subscriber identification card 105.
In the electronic device 100, during the start-up process of the modem chip 102, the switching unit 104 switches the connection state according to whether the identification card connection unit 103 is electrically connected to the subscriber identification card 105, and when the identification card connection unit 103 is not electrically connected to the subscriber identification card 105, the modem chip 102 and the embedded subscriber identification chip 101 are connected, so that the modem chip 102 and the embedded subscriber identification chip 101 can communicate with each other, and when the identification card connection unit 103 is electrically connected to the subscriber identification card 105, the modem chip 102 and the subscriber identification card 105 are connected, so that the modem chip 102 and the subscriber identification card 105 can communicate with each other, and finally, the communication switching between the embedded subscriber identification chip 101 and the subscriber identification card 105 is realized.
Therefore, on one hand, for example, in a scenario where the electronic device 100 is maintained, leased, used, and subjected to an authentication and admission test, the electronic device 100 accesses the subscriber identity card 105, and then in a process of powering up again and starting up, the modem chip 102 and the subscriber identity card 105 can be automatically connected, so that communication can be performed between the modem chip 102 and the subscriber identity card 105, and thus when the subscriber identity card 105 is accessed, a data traffic corresponding to the subscriber identity card 105 is automatically used, and a traffic of the embedded subscriber identity chip 101 itself is prevented from being consumed; on the other hand, in a normal scenario, the electronic device 100 does not access the subscriber identity module 105, and at this time, the electronic device 100 can automatically connect the modem chip 102 and the embedded subscriber identity module 101, so that the modem chip 102 and the embedded subscriber identity module 101 can communicate with each other, which improves convenience, flexibility, reliability and security of the electronic device 100 during application, and meets both application requirements of the electronic device 100 in a normal application scenario and application requirements in a special application scenario, thereby solving application difficulties of the electronic device 100 in an actual application process.
In at least one embodiment, as shown in fig. 3, fig. 3 is a block diagram of a second structure of the electronic device 100 according to the embodiment of the present disclosure, in which the modem chip 102 includes a control unit 1021, and the control unit 1021 is electrically connected to both the switching unit 104 and the identification card connection unit 103.
The control unit 1021 is configured to control the switching unit 104 to maintain the current switching state until the control unit 1021 restarts according to the connection state corresponding to whether the identification card connection unit 103 is electrically connected to the subscriber identification card 105.
In the process of starting the modem chip 102, the control unit 1021 in the electronic device 100 is powered on and started, the identification card connection unit 103 informs the switching unit 104 of the connection status of whether the identification card connection unit 103 is electrically connected with the subscriber identity module 105, at this time, if the identification card connection unit 103 is electrically connected with the subscriber identity module 105, the switching unit 104 connects the modem chip 102 with the subscriber identity module 105, and if the identification card connection unit 103 is not electrically connected with the subscriber identity module 105, the switching unit 104 connects the modem chip 102 with the embedded subscriber identity module 101, so that the subscriber identity module 105 and the embedded subscriber identity module 101 can be switched in time.
The control unit 1021 is electrically connected with the switching unit 104 and the identification card connecting unit 103, and the control unit 1021 can acquire a connection state corresponding to whether the identification card connecting unit 103 is electrically connected with the subscriber identification card 105, and after the control unit 1021 is started, further processing is performed to control the switching unit 104 to keep the current switching state until the control unit 1021 is restarted according to the connection state corresponding to whether the identification card connecting unit 103 is electrically connected with the subscriber identification card 105.
For example, when the identification card connection unit 103 is electrically connected to the subscriber identification card 105, the control unit 1021 outputs a high level signal to the switch unit 104 to maintain the current switching state of the switch unit 104 until the control unit 1021 is restarted, and when the identification card connection unit 103 is not electrically connected to the subscriber identification card 105, the control unit 1021 outputs a low level signal to the switch unit 104 to maintain the current switching state of the switch unit 104 until the control unit 1021 is restarted.
By arranging the control unit 1021, in the starting process of the control unit 1021, when the electrical connection between the subscriber identity module 105 and the identity module card connecting unit 103 is not established, the electronic device 100 can be enabled to connect the modem chip 102 and the embedded subscriber identity module chip 101, so that the embedded subscriber identity module chip 101 works; when the subscriber identity card 105 establishes an electrical connection with the identity card connection unit 103, the subscriber identity card 105 is enabled.
Further, the control unit 1021 controls the switching unit 104 to keep the current switching state after the control unit 1021 is started up, and further the electronic device 100 switches the embedded subscriber identity module 101 and the subscriber identity module 105 only when the control unit 1021 is started up, after the control unit 1021 finishes the activation, since the control unit 1021 outputs the level control signal to the switching unit 104 to maintain the current switching state, even if the connection state between the subscriber identification card 105 and the identification card connection unit 103 changes, the current switching state corresponding to the switching unit 104 remains unchanged, until the control unit 1021 is restarted, the switching unit 104 performs automatic switching between the embedded subscriber identity module 101 and the switching subscriber identity module 105 again according to the connection status corresponding to whether the identity card connecting unit 103 is electrically connected with the subscriber identity module 105.
The electronic device 100 described above implements communication switching between the embedded ue 101 and the ue 105, wherein after the electronic device 100 is connected to the ue 105 and powered on and restarted, even if the corresponding user unplugs the ue 105, the electronic device 100 still controls the switching unit 104 through the control unit 1021 to keep the current switching state unchanged, in other words, the switching unit 104 does not perform switching due to an unplugging action of the ue 105 until the control unit 1021 restarts, so as to avoid that the electronic device 100 consumes the flow of the embedded ue 101 itself when unplugging the ue 105 after restarting, thereby satisfying the application requirements of the electronic device 100 in a special application scenario, and improving convenience, flexibility and security of the electronic device 100 during application.
