It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. The electronic device 1 may be a Customer Premise Equipment (CPE), or may also be other devices, such as a router, a mobile phone, a network converter, and the like. And is not particularly limited herein. The customer premises equipment 1 is used to implement a network access function that can convert the operator public network WAN to the user home local area network LAN. According to the current broadband access mode of the internet, the access mode can be classified into FTTH (fiber to the home), DSL (digital telephone line access), Cable (Cable television line access), Mobile (Mobile access, i.e. wireless CPE) and the like.

In the embodiment shown in fig. 1, the interface 13 includes a power interface 131, a USB interface 133, a network cable interface 135, a telephone interface 136, and the like. The power interface 131 is used to connect an external power source to supply power to the client front-end device 1, the USB interface 133 is used for data transmission between the client front-end device 1 and the external device, and the telephone interface 136 is used to connect an external fixed telephone. Of course, the USB interface 133 and the power supply interface 131 may be integrated to simplify the arrangement of the interface 13 of the client front end device 1. The network interface 135 may further include a wired network access terminal and a wired network output terminal. The customer premise equipment 1 may access the network through a wired network access terminal, and then be connected to other equipment through one or more wired network output terminals. Of course, in some embodiments, the network interface 135 and the telephone interface 136 may be integrated to simplify the arrangement of the interface 13 of the customer premises equipment 1. Of course, in some embodiments, the wired network output may be the default, that is, after the client front-end device 1 accesses the network by using the wired network input, the wired network is converted into a wireless network (for example, WiFi) by using the radio frequency system, so that the external device can access the network. Of course, both the wired network access terminal and the wired network output terminal may be omitted, and in this embodiment, the customer premises equipment 1 may access a cellular network (also referred to as a mobile network) through the radio frequency system, and then convert into a WiFi signal for an external device to access the network. The circuit board may also be provided with a card socket 380 exposed to the housing 12, the card socket 380 being usable for a user to insert and remove a SIM card.

Referring to fig. 2, fig. 2 is a second structural schematic diagram of an electronic device according to an embodiment of the present disclosure. The electronic device 1 includes a radio frequency chip 320, a switch 340, an embedded subscriber identity card 360(eSIM card), and a card socket 380. The switch 340 includes a fixed connection end 342, a first connection end 344, a second connection end 346 and a control end 348, and the control end 348 can control the fixed connection end 342 to be conducted with the first connection end 344 or the second connection end 346. An embedded subscriber identity card 360(eSIM card) is electrically connected to the first connection terminal 344. Card socket 380 is electrically connected to second connection terminals 346, and card socket 380 can be used to receive plug-in subscriber identity card 400(SIM card). The rf chip 320 is electrically connected to the fixed connection 342, i.e., the rf chip 320 can be connected to an eSIM card or a SIM card through the switch 340.

The control terminal 348 is electrically connected to the rf chip 320 and the card socket 380, and the control terminal 348 controls the connection between the fixed connection terminal 342 and the first connection terminal 344 or the second connection terminal 346 according to a signal of the card socket 380 and/or the rf chip 320.

In the related art, an eSIM card is arranged inside the electronic device, and the electronic device receives the mobile signal through the eSIM card and forwards the mobile signal through a wireless WIFI signal. However, in some cases, the electronic device receives the mobile signal using the SIM card, and at this time, the electronic device needs to be disassembled, the eSIM card is disconnected and the SIM card is externally connected, and after the maintenance is completed, the SIM card needs to be removed and the eSIM card needs to be reconnected. For example, when the electronic device needs to receive a mobile signal through the SIM card, the electronic device needs to be repaired when the eSIM card has a problem, or the electronic device needs to be authenticated and tested for admission, or another user needs to receive a mobile signal through the SIM card after the electronic device is rented, or the user wants to replace an operator through the SIM card.

In this embodiment, the rf chip 320 can be selectively connected to the embedded subscriber identity module card 360(eSIM card) or the card socket 380 through the switch 340, the card socket 380 can be connected to the plug-in subscriber identity module card 400(SIM card), and the switching between the embedded subscriber identity module card 360(eSIM card) or the plug-in subscriber identity module card 400(SIM card) can be performed only by controlling the switching of the switch 340 without using a complicated technical means, so as to improve the convenience of switching between the embedded subscriber identity module card 360(eSIM card) and the plug-in subscriber identity module card 400(SIM card). Moreover, the rf chip 320 and the card socket 380 are both connected to the control terminal 348 of the switch 340, and both the rf chip 320 and the card socket 380 can control the switch 340 to switch, so as to provide a richer control manner and be applicable to more use cases. For example, the card socket 380 can control the switch 340 to switch, and the rf chip 320 can also control the switch 340 to switch.

It is understood that an embedded subscriber identity module card (eSIM card) is a chip fixed in an electronic device, and a plug-in subscriber identity module card (SIM card) is removably installed in the electronic device.

Referring to fig. 3, fig. 3 is a third structural schematic diagram of an electronic device according to an embodiment of the present disclosure. The card socket 380 includes a detecting part 382, a level of the detecting part 382 is a first level when the card socket 380 is not electrically connected to the plug-in subscriber identity card, such as when the plug-in subscriber identity card is not inserted into the card socket, and a level of the detecting part 382 is a second level when the card socket 380 is electrically connected to the plug-in subscriber identity card, such as when the plug-in subscriber identity card is inserted into the card socket, the second level being different from the first level.

The control terminal 348 is electrically connected to the detection unit 382, when the level of the detection unit 382 is a first level, the control terminal 348 controls the fixed connection terminal 342 to be electrically connected to the first connection terminal 344, and when the level of the detection unit 382 is a second level, the control terminal 348 controls the fixed connection terminal 342 to be electrically connected to the second connection terminal 346.

The control terminal 348 of the switch 340 may determine whether the card socket port is electrically connected to the plug-in type subscriber identity module card through the level of the detection portion 382 of the card socket 380, and then the control terminal 348 may control the fixed connection terminal 342 to select the first connection terminal 344 or the second connection terminal 346 to be turned on, so that the rf chip 320 is electrically connected to the plug-in type subscriber identity module card or the embedded type subscriber identity module card 360. Specifically, when it is determined that the card socket 380 is electrically connected to the plug-in type subscriber identity card, the control switch 340 electrically connects the radio frequency chip 320 to the plug-in type subscriber identity card, i.e., receives the movement signal through the plug-in type subscriber identity card, and when it is determined that the card socket 380 is not electrically connected to the plug-in type subscriber identity card, the control switch 340 electrically connects the radio frequency chip 320 to the embedded type subscriber identity card 360, i.e., receives the movement signal through the embedded type subscriber identity card 360. The control terminal 348 of the switch 340 is directly electrically connected to the detection portion 382 of the card socket 380, and the switch 340 can be switched quickly according to the level of the detection portion 382, with a high switching speed and almost no time delay in the middle.

Determining whether card socket 380 is electrically connected to the plug-in customer identification card through a level change of detection part 382 of card socket 380 may be performed in various ways. Illustratively, the detection portion 382 of the card socket 380 may be used to change the level after being electrically connected with the plug-in customer identification card. For example, when no SIM card is inserted into the electronic apparatus 1, the detection section 382 of the card socket 380 is disconnected to a low level, and when a SIM card is inserted into the electronic apparatus 1, the detection section 382 of the card socket 380 is electrically connected to the SIM card and becomes a high level. In another example, the detection part 382 of the card socket 380 may be used to change the level by a physical change of pulling out the card socket after the plug-in customer recognition card is inserted. For example, when no SIM card is inserted into the electronic apparatus 1, the detection unit 382 of the card socket 380 is electrically connected to a certain interface, and the level of the detection unit 382 is set to a low level, and when a SIM card is inserted into the electronic apparatus 1, the detection unit 382 of the card socket 380 is disconnected from the certain interface, and the level of the detection unit 382 is set to a high level.

Wherein, after the fixed connection terminal 342 and the second connection terminal 346 are conducted, the rf chip 320 receives the mobile signal through the plug-in sim card. If the plug-in type subscriber identity module card is an invalid card (e.g., the card is a waste card, an incompatible card, a damaged card of an internal circuit, an improperly installed card, etc.), the rf chip 320 cannot receive the mobile signal through the plug-in type subscriber identity module card, and the electronic device 1 is switched to the rf chip 320 to be electrically connected to the plug-in type subscriber identity module card, then the electronic device 1 cannot normally operate, and even if the electronic device 1 is restarted, the plug-in type subscriber identity module card is reselected, so that the electronic device 1 cannot normally operate. In this embodiment, the rf chip 320 may detect whether the plug-in subscriber identity module card is an invalid card, and if the plug-in subscriber identity module card is detected as an invalid card, the fixed connection end 342 and the first connection end 344 are controlled to be connected, that is, switched to receive the mobile signal through the eSIM card.

The rf chip 320 may detect whether the plug-in type subscriber identity module card is an invalid card by a current value or a voltage value in a circuit connected with the plug-in type subscriber identity module card, and if the current value or the voltage value in the circuit is out of a normal range, the plug-in type subscriber identity module card is considered as an invalid card. The signal transmitted or received by the plug-in customer identification card can also be used to detect whether the plug-in customer identification card is an invalid card, for example, the plug-in customer identification card is selected as an invalid card if no information returned by the base station or other electronic equipment is received. The strength of the signal transmitted by the plug-in type customer identification card can be detected to detect whether the plug-in type customer identification card is an invalid card, and if the strength of the transmitted signal is less than the threshold value, the plug-in type customer identification card is considered as an invalid card.

Referring to fig. 4, fig. 4 is a schematic view illustrating a fourth structure of an electronic device according to an embodiment of the present disclosure. The first level is lower than the second level, and when the SIM card is not inserted into the electronic device 1, the detecting portion 382 of the card socket 380 is at the low level, and when the SIM card is inserted into the electronic device 1, the detecting portion 382 of the card socket 380 is at the high level. The electronic device 1 further includes a first resistor 372 and a ground terminal 374, the detecting part 382 is connected to the ground terminal 374 through the first resistor 372, the rf chip 320 includes a control pin 322, and the control pin 322 is connected between the detecting part 382 and the first resistor 372. Since detecting unit 382 is grounded via first resistor 372, the voltage of detecting unit 382 will not be 0 even when detecting unit 382 is pulled low. At this time, the control pin 322 can pull up the detection unit 382 at a low level, and the first resistor 372 can stabilize the level value of the detection unit 382.

Optionally, the control pin 322 may be an output pin. After the fixed connection terminal 342 and the second connection terminal 346 are conducted, if the rf chip 320 detects that the plug-in sim card is an invalid card, the control pin 322 outputs a third level, where the third level is smaller than the second level, so that the control terminal 348 controls the fixed connection terminal 342 to be conducted with the first connection terminal 344 according to the third level.

When the plug-in subscriber identity module card is an invalid card, the rf chip 320 may control the switch 340 through the control pin 322, so that the invalid plug-in subscriber identity module card connected to the rf chip 320 is switched to an eSIM card, thereby effectively solving the problem that the plug-in subscriber identity module card is an invalid card.

For example, when the SIM card is inserted into the electronic device 1, the detecting portion 382 of the card socket 380 is at a high level, the detecting portion 382 is electrically connected to the control terminal 348, and the control terminal 348 is also at a high level, so as to control the fixed connection terminal 342 and the second connection terminal 346 to be conducted, so that the rf chip 320 is conducted with the SIM card. After the rf chip 320 is connected to the SIM card, if the rf chip 320 detects that the SIM card is an invalid card, the control pin 322 is controlled to output a low level, such as a third level, and the control pin 322 outputs the third level, which can pull down the level of the control terminal 348, so that the control terminal 348 is at the low level, and thus the fixed connection terminal 342 is controlled to switch to be connected to the first connection terminal 344, so that the rf chip 320 is connected to the eSIM card.

Optionally, the control pin 322 may also be an input/output pin. When the electronic device 1 is powered on and started, the control pin 322 is in an input state, and the level of the detection part 382 is acquired; when the fixed connection terminal 342 and the second connection terminal 346 are conducted, if the rf chip 320 detects that the plug-in sim card is an invalid card, the control pin 322 is controlled to be in an output state and outputs a third level, where the third level is smaller than the second level, so that the control terminal 348 controls the fixed connection terminal 342 to be conducted with the first connection terminal 344 according to the third level.

The rf chip 320 may obtain information about the SIM card inserted into the electronic device 1 through the control pin 322, and when the rf chip 320 identifies that the plug-in subscriber identity module card is an invalid card, the switch 340 may be controlled through the control pin 322, so that the invalid plug-in subscriber identity module card connected to the rf chip 320 is switched to an eSIM card, thereby effectively solving the problem that the plug-in subscriber identity module card is an invalid card.

For example, when the SIM card is inserted into the electronic device 1, the detecting portion 382 of the card socket 380 is at a high level, the detecting portion 382 is electrically connected to the control terminal 348, and the control terminal 348 is also at a high level, so as to control the fixed connection terminal 342 and the second connection terminal 346 to be conducted, so that the rf chip 320 is conducted with the SIM card. Meanwhile, the control pin 322 of the rf chip 320 is in an input state, and the control pin 322 can obtain the high level of the detecting portion 382, so as to determine that the SIM card is inserted into the electronic device 1. After the rf chip 320 is connected to the SIM card, if the rf chip 320 detects that the SIM card is an invalid card, the control pin 322 is controlled to be in an output state and outputs a low level, such as a third level, and the control pin 322 outputs the third level, which can pull down the level of the control terminal 348 to make the control terminal 348 be the low level, so as to control the fixed connection terminal 342 to switch to be connected to the first connection terminal 344, so that the rf chip 320 is connected to the eSIM card.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a fifth electronic device according to an embodiment of the present disclosure. The rf chip 320 includes a detection pin 324 and a control pin 322, the detection pin 324 is electrically connected to the detection portion 382 and obtains a level of the detection portion 382, and the control pin 322 is electrically connected to the control terminal 348 and is configured to output a control signal for controlling the control terminal 348 to be electrically connected to the first connection terminal 344 or the second connection terminal 346.

The detection pin 324 is used for acquiring whether the SIM card is inserted into the electronic device 1 through the detection unit 382, and the control pin 322 is used for controlling the switch 340. The level of the detection portion 382 can quickly control the switching of the switch 340, for example, when the electronic device 1 is powered on and started, the control terminal 348 of the switch 340 can quickly select a SIM card or an eSIM card according to the level of the detection portion 382, after the electronic device 1 is started, the radio frequency chip 320 can receive a mobile signal according to the SIM card or the eSIM card selected by the switch 340, and if the SIM card is an invalid card, the radio frequency chip 320 can also control the switching of the switch 340 through the control pin 322, so that the SIM card connected to the radio frequency chip 320 is switched to the eSIM card.

Referring to fig. 6 and 7, fig. 6 is a schematic structural diagram of a card socket in an electronic device according to an embodiment of the present application, and fig. 7 is an exploded schematic diagram of the card socket shown in fig. 6. The card socket 380 includes the connecting member 140 and the detecting spring 160, and the detecting spring 160 can be used as the detecting portion in the above embodiments. When the plug-in SIM card is not inserted into the card socket 380, the detecting spring 160 is electrically connected to the connecting member 140, so that the level of the detecting spring 160 is a first level; when the plug-in subscriber identity module card is inserted into the card socket 380, the detection spring 160 is separated from the connection member 140, so that the level of the detection spring 160 is a second level. The level of the detection elastic sheet 160 is changed by detecting the physical connection between the elastic sheet 160 and the connecting piece 140, so that even if the SIM card is inserted into the card holder 380 in place or the SIM card is invalid, the detection of the detection elastic sheet 160 is not influenced, whether the SIM card is inserted into the card holder 380 can be accurately detected, and the accuracy of the detection of the SIM card by the card holder 380 is improved.

Referring to fig. 6 and 7, the card socket 380 may further include a bracket 120, the connecting member 140 and the detecting elastic sheet 160 are disposed on the bracket 120, when the SIM card is not inserted into the card socket 380, the detecting elastic sheet 160 is electrically connected to the connecting member 140, and when the SIM card is inserted into the card socket 380, the detecting elastic sheet 160 is disposed at an interval from the connecting member 140. Whether a SIM card is inserted into the card socket 380 can be determined by detecting the connection state of the elastic sheet 160 and the connecting member 140. Whether the SIM card is inserted into the card seat 380 or not can be accurately obtained by physically abutting and separating the detection elastic sheet 160 and the connecting piece 140, so that the accuracy of detecting whether the SIM card is inserted into the card seat 380 or not is improved.

It should be noted that, in the related art, a detection circuit connected to the SIM card is disposed in the card socket, when the SIM card is not inserted into the card socket, the detection circuit is open, and when the SIM card is inserted into the card socket, the detection circuit is electrically connected to the SIM card to form a loop, thereby detecting that the SIM card is inserted into the card socket. However, if the SIM card is not inserted into the card socket in place or the SIM card is invalid, the effective detection cannot be performed.

The present embodiment detects whether a SIM card is inserted into the card socket 380 by detecting the physical connection of the elastic sheet 160 and the connection member 140. When the SIM card is not inserted into the card socket 380, the detection elastic sheet 160 abuts against the connecting piece 140 to realize electrical connection, and when the SIM card is inserted into the card socket 380, the detection elastic sheet 160 is pressed by the SIM card to separate from the connecting piece 140, so that the detection elastic sheet 160 and the connecting piece 140 are arranged at intervals, and the level of the detection elastic sheet 160 is not influenced by the connecting piece 140 any more. For example, when the SIM card is not inserted into the card socket 380, the detecting elastic sheet 160 is electrically connected to the connecting member 140, the connecting member 140 may affect the level of the detecting elastic sheet 160, for example, the level of the detecting elastic sheet 160 is low level, when the SIM card is inserted into the card socket 380, the detecting elastic sheet 160 is pressed by the SIM card to separate from the connecting member 140, the level of the detecting elastic sheet 160 is no longer pulled down by the connecting member 140, and the detecting elastic sheet 160 changes from low level to high level, therefore, it can be determined whether the SIM card is inserted through the level change identification of the detecting elastic sheet 160, the level change of the detecting elastic sheet 160 is determined by the physical connection or physical separation of the detecting elastic sheet 160 and the connecting member 140, even if the SIM card is not inserted into the card socket 380, or the SIM card is invalid, and the detection of the SIM card is not affected by the detection of the detecting elastic sheet 160, and whether the SIM card is inserted into the card socket 380 can be accurately detected.

For example, if the first remaining flow value is greater than the second remaining flow value, the eSIM card is selected to be connected with the radio frequency chip. And if the first residual flow value is smaller than the second residual flow value, selecting the SIM card to be connected with the radio frequency chip. The selection can also be performed according to the setting of the user, for example, when the flow package of the SIM card is due soon, the SIM card is selected to be connected with the radio frequency chip as long as the second remaining flow value is not smaller than a preset value. The eSIM card can be selected to be connected with the rf chip according to a priority, for example, the priority of the eSIM card is higher, as long as the first remaining traffic value is not greater than a preset value. Or the priority of the SIM card is higher, and the flow of the SIM card is switched to the eSIM card after being used.
