TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic devices, and in particular to an electronic device, a communication control method, and a computer readable storage medium. BACKGROUND

[0002] With the rapid development of mobile communication technology, terminal devices with cellular functions have become necessities in people's daily life. At the same time, with the wide application of satellite positioning technology, terminal devices supporting satellite positioning have also been increasingly concerned. At present, due to size limitations and narrow frame designs, terminal devices with cellular functions and satellite positioning functions on the market usually integrate cellular functions and satellite positioning functions into a single antenna structure. However, this will not fully utilize the performance of the antenna, affecting the communication quality. SUMMARY

[0003] To solve the above technical problems, the present application provides an electronic device, a communication control method, and a computer readable storage medium.

[0004] The first aspect of the present application provides an electronic device, which comprises a cellular communication module, an antenna, and a matching tuning unit. The antenna comprises a matching tuning point, and the matching tuning unit is connected to the matching tuning point of the antenna. The matching tuning unit comprises a first matching state and a second matching state. When the matching tuning unit is in the first matching state, the antenna supports a cellular communication frequency band. When the matching tuning unit is in the second matching state, the antenna supports a satellite positioning frequency band. After the cellular communication module enters a non-working state, the matching tuning unit is in the second matching state, so that the antenna supports the satellite positioning frequency band.

[0005] The electronic device provided by the present application comprises a matching tuning unit, which has a first matching state and a second matching state corresponding to a cellular communication frequency band and a satellite positioning frequency band, respectively. Thus, by switching the matching state of the matching tuning unit, the antenna can support different communication frequency bands. When the cellular communication module is in a non-working state, the matching tuning unit will switch to the second matching state so that the antenna supports the satellite positioning frequency band. Thus, not only can satellite positioning be performed when the cellular communication module is not working, but also the performance of the antenna for satellite positioning can be fully utilized, ensuring the communication quality of satellite positioning.

[0006] In a possible implementation, the matching tuning unit comprises a cellular matching circuit, a satellite positioning matching circuit, and a first switch unit, the first switch unit is configured to select the cellular matching circuit or the satellite positioning matching circuit to be enabled, so that the matching tuning unit is in the first matching state or the second matching state. Thus, the cellular matching circuit or the satellite positioning matching circuit can be intelligently selected by the first switch unit, so that the antenna can support different communication frequency bands under different communication requirements, and both can provide better signal receiving and transmitting performance.

[0007] In a possible implementation, the first switch unit is connected between the cellular matching circuit and the satellite positioning matching circuit and the ground, and the cellular matching circuit and the satellite positioning matching circuit are connected in parallel between the first switch unit and the matching tuning point; the first switch unit is configured to selectively turn on the electrical connection between the cellular matching circuit and the ground or the electrical connection between the satellite positioning matching circuit and the ground, so that the cellular matching circuit is enabled to make the matching tuning unit in the first matching state, or the satellite positioning matching circuit is enabled to make the matching tuning unit in the second matching state.

[0008] The cellular matching circuit and the satellite positioning matching circuit are connected in parallel, and each matching circuit corresponds to a frequency band independently. This design makes it possible to optimize the matching for each frequency band independently, reducing the difficulty of matching design. In addition, the parallel structure also helps to reduce signal interference and improve communication performance.

[0009] In a possible implementation, the cellular matching circuit comprises a first matching element and a second matching element, the satellite positioning matching circuit comprises the second matching element, the first switch unit is connected between the first matching element and the ground, the first matching element is connected between the first switch unit and the matching tuning point, and the second matching element is connected between the matching tuning point and the ground; the first switch unit is configured to turn on or turn off the electrical connection between the first matching element and the ground, so that the cellular matching circuit is enabled to make the matching tuning unit in the first matching state, or the satellite positioning matching circuit is enabled to make the matching tuning unit in the second matching state.

[0010] By designing the cellular matching circuit and the satellite positioning matching circuit to share the second matching element, the number of elements can be reduced, which helps to reduce the cost.

[0011] In a possible implementation, the cellular matching circuit and the satellite positioning matching circuit are connected in parallel between the first switch unit and the ground, and the first switch unit is connected between the cellular matching circuit and the satellite positioning matching circuit and the matching tuning point; the first switch unit is configured to selectively enable electrical connection between the cellular matching circuit and the matching tuning point or electrical connection between the satellite positioning matching circuit and the matching tuning point, so that the cellular matching circuit is enabled to enable the matching tuning unit to be in the first matching state, or the satellite positioning matching circuit is enabled to enable the matching tuning unit to be in the second matching state.

[0012] Each matching circuit corresponds to a frequency band independently, and this design enables independent matching optimization for each frequency band, thereby reducing the difficulty of matching design.

[0013] In a possible implementation, the electronic device further includes a satellite positioning module and a power supply module, and the satellite positioning module and the cellular communication module are configured to jointly control the power supply module to supply power to the first switch unit in the matching tuning unit, and are configured to jointly control the first switch unit in the matching tuning unit to enable the cellular matching circuit or the satellite positioning matching circuit, so that the matching tuning unit is in the first matching state or the second matching state.

[0014] By jointly controlling the satellite positioning module and the cellular communication module, the limitation of single-module control can be avoided, and the system reliability can be improved. For example, when one of the modules is in a non-working state or is abnormal, the other module can be used to control the power supply and the first switch unit, to ensure that the first switch unit continuously and stably works, and to ensure that the matching state of the matching tuning unit meets the communication requirement. Therefore, the matching tuning unit can be controlled to be in the second matching state at the moment when the cellular communication module enters a non-working state or before or after the moment.

[0015] In a possible implementation, when the cellular communication module is in a normal working state and / or the satellite positioning module is in a normal working state, the satellite positioning module and the cellular communication module control the power supply module to supply power to the first switch unit.

[0016] Therefore, when one of the cellular communication module and the satellite positioning module is in a non-working state, the other can control the power supply to supply power to the first switch unit, thereby avoiding the problem that the matching tuning unit cannot be in a required matching state due to the non-working state of one of the modules.

[0017] In a possible implementation, the electronic device further comprises a first logic circuit connected between the cellular communication module, the satellite positioning module and the first switch unit, the cellular communication module and the satellite positioning module are configured to output a first switch control signal and a second switch control signal respectively, and the first logic circuit is configured to convert the switch logic for controlling the first switch unit according to the first switch control signal and the second switch control signal, so as to control the first switch unit to select the cellular matching circuit or the satellite positioning matching circuit to be enabled, thereby controlling the matching tuning unit to be in the first matching state or the second matching state.

[0018] The first logic circuit can intelligently manage the cellular communication and satellite positioning functions, that is, automatically switch the matching state of the matching tuning unit according to the working state of the cellular communication module.

[0019] In a possible implementation, the electronic device further comprises a power supply module, the cellular communication module is configured to control the power supply module to supply power to the first switch unit, and control the first switch unit to select the satellite positioning matching circuit to be enabled before entering the non-working state, so that the matching tuning unit is in the second matching state.

[0020] Therefore, the first switch unit can be powered only by the cellular communication module, and the matching state of the matching tuning unit can be controlled only by the cellular communication module, thereby simplifying the circuit structure of the cellular communication and satellite positioning integrated system and reducing the hardware complexity.

[0021] In a possible implementation, the non-working state of the cellular communication module is a sleep state when the cellular communication module is in an idle state, an RRC connected state or a network searching state.

[0022] When the cellular communication module enters the sleep state, it does not need to perform cellular communication, at this time, by controlling the matching tuning unit to be in the second matching state, the antenna supports the satellite positioning frequency band, the antenna can be effectively utilized, the utilization rate of the antenna is improved, and the positioning demand can be met.

[0023] In a possible implementation, the electronic device further comprises a controller and a satellite positioning module, the controller is configured to send a notification signal to the cellular communication module and / or the satellite positioning module when the electronic device is in a preset state, so as to notify the cellular communication module and / or the satellite positioning module to control the matching tuning unit to be in the second matching state and control the cellular communication module to enter the non-working state.

[0024] Thus, the controller can manage and coordinate the control of the first switch unit by the cellular communication module and the satellite positioning module according to the state of the electronic device, and control the working state of the cellular communication module according to the state of the electronic device.

[0025] In a possible implementation, the preset state includes at least one of the following: the electronic device enters a flight mode; the electronic device establishes a communication connection with a terminal, and a mobile communication unit of the terminal is in normal operation; and the electronic device does not activate an identity recognition card.

[0026] When the electronic device is in the flight mode, the electronic device does not need to perform cellular communication. By controlling the matching tuning unit to be in the second matching state, the antenna can support the satellite positioning frequency band, so that the electronic device can effectively utilize the antenna to perform satellite positioning in the flight mode, and the antenna performance for satellite positioning can be fully ensured, thereby improving the accuracy of a satellite positioning track.

[0027] When the electronic device is in communication connection with the terminal, it can be considered that cellular communication is not needed at this time. By controlling the matching tuning unit to be in the second matching state, the antenna can support the satellite positioning frequency band, so that the electronic device can effectively utilize the antenna to perform satellite positioning when the electronic device is in communication connection with other devices, and the antenna performance for satellite positioning can be fully ensured, thereby improving the accuracy of a satellite positioning track. The communication connection between the electronic device and the terminal can include Bluetooth connection, Wifi connection or wired connection between the electronic device and the terminal.

[0028] When the electronic device does not activate the identity recognition card, for example, the identity recognition card is not inserted into the electronic device or the identity recognition card is not set, or the electronic device is installed with the identity recognition card but the identity recognition card does not work, it indicates that the electronic device does not have the condition to access cellular communication, that is, the electronic device cannot perform cellular communication. By controlling the matching tuning unit to be in the second matching state, the antenna can support the satellite positioning frequency band, so that the electronic device can effectively utilize the antenna to perform satellite positioning in the case that the identity recognition card is not activated, and the antenna performance for satellite positioning can be fully ensured, thereby improving the accuracy of a satellite positioning track.

[0029] In a possible implementation, the electronic device includes a wearable device, and the terminal includes a mobile phone.

[0030] In a possible implementation, the non-working state is a power-off state or a sleep state.

[0031] In a possible implementation, the matching tuning unit is in the first matching state after the cellular communication module enters a normal working state, so that the antenna supports a cellular communication frequency band. Thus, not only can cellular communication be performed when the cellular communication module is in normal working state, but also the antenna performance for cellular communication can be fully exerted, thereby ensuring the quality of cellular communication. By adjusting the matching state of the matching tuning unit according to the working state of the cellular communication module, the antenna can support the cellular communication frequency band and the satellite positioning frequency band respectively, thereby not only improving the utilization rate of the antenna, but also supporting corresponding communication functions under different communication demands such as cellular communication demand and satellite positioning demand, effectively supporting multiple communication functions, and realizing coexistence of the cellular communication function and the satellite positioning function.

[0032] The second aspect of the present application provides a communication control method applied to the electronic device provided in the first aspect. The communication control method comprises: controlling the matching tuning unit to be in the second matching state after the cellular communication module enters a non-working state, so that the antenna supports a satellite positioning frequency band.

[0033] The communication control method provided in the second aspect above is applied to the electronic device provided in the first aspect, and therefore can achieve the same or corresponding beneficial effects as the electronic device provided in the first aspect, which will not be described herein again.

[0057] Please refer to Figure 1 , the structural schematic diagram of the electronic device 100 in some embodiments of the present application. In some embodiments, as shown inFigure 1 As shown, the electronic device 100 comprises a cellular communication module 10, an antenna 20 comprising a matching tuning point 21, and a matching tuning unit 30 connected to the matching tuning point 21 of the antenna 20. The matching tuning unit 30 comprises a first matching state and a second matching state, wherein the antenna 20 supports a cellular communication frequency band when the matching tuning unit 30 is in the first matching state, and the antenna 20 supports a satellite positioning frequency band when the matching tuning unit 30 is in the second matching state. The matching tuning unit 30 is in the second matching state after the cellular communication module 10 enters a non-working state, so that the antenna 20 supports the satellite positioning frequency band.

[0058] The electronic device 100 provided in the present application comprises a matching tuning unit 30 having a first matching state and a second matching state corresponding to a cellular communication frequency band and a satellite positioning frequency band respectively, so that the antenna 20 can support different communication frequency bands by switching the matching state of the matching tuning unit 30. When the cellular communication module 10 is in a non-working state, the matching tuning unit 30 will switch to the second matching state so that the antenna 20 supports the satellite positioning frequency band, so that not only can satellite positioning be performed when the cellular communication module 10 is not working, but also the antenna performance for satellite positioning can be fully utilized to ensure the communication quality of satellite positioning.

[0059] The cellular communication frequency band can comprise at least one of a low frequency (LB) band, a medium frequency (MB) band, and a high frequency (HB) band.

[0060] In some embodiments, the matching tuning unit 30 is in the first matching state after the cellular communication module 10 enters a normal working state, so that the antenna 20 supports the cellular communication frequency band. The non-working state of the cellular communication module 10 can be a state other than the normal working state.

[0061] Thus, not only can cellular communication be performed when the cellular communication module 10 is in normal operation, but also the antenna performance for cellular communication can be fully exerted, and thus the quality of cellular communication can be ensured. By adjusting the matching state of the matching tuning unit 30 according to the working state of the cellular communication module 10, the antenna 20 can support the cellular communication frequency band and the satellite positioning frequency band, respectively, and thus not only the utilization rate of the antenna is improved, but also the corresponding communication function can be supported under different communication requirements, such as cellular communication requirement and satellite positioning requirement, and thus various communication functions can be effectively supported, and the coexistence of cellular communication function and satellite positioning function is realized.

[0062] Further reference is made to Figure 2 , Figure 2 is a schematic structural diagram of an electronic device in some embodiments of the present application. As shown in Figure 2 , the cellular communication module 10 includes a first modem 11, a first radio frequency chip (RFIC) 12, and a first radio frequency front-end module 13, and the first RFIC 12 is connected between the first modem 11 and the first radio frequency front-end module 13.

[0066] In some embodiments, the non-working state of the satellite positioning module 40 is a power down state or a sleep state. In the power down state or the sleep state, the second modem 41 can be in a power down state or a sleep state. Therefore, in some embodiments, the satellite positioning module 40 can only comprise the second modem 41.

[0067] In the following figures, the cellular communication module 10 comprises a first modem 11, a first RFIC 12 and a first RF front-end module 13, and the satellite positioning module 40 comprises a second modem 41, a second RFIC 42 and a second RF front-end module 43.

[0068] Please refer to Figure 3 , which is a schematic diagram of the matching tuning unit 30 in some embodiments of the present application. In some embodiments, as shown in Figure 3 , the matching tuning unit 30 comprises a cellular matching circuit 31, a satellite positioning matching circuit 32 and a first switching unit 33. The first switching unit 33 is configured to select the cellular matching circuit 31 or the satellite positioning matching circuit 32 to be enabled, so that the matching tuning unit 30 is in the first matching state or the second matching state. Therefore, the cellular matching circuit 31 or the satellite positioning matching circuit 32 can be intelligently selected by the first switching unit 33, so that the antenna 20 can support different communication frequency bands under different communication requirements, and both can provide better signal reception and transmission performance.

[0069] In some embodiments, as shown in Figure 3 , the number of the cellular matching circuit 31 can be one, and the cellular communication frequency band can comprise one, for example, one of the B5 frequency band, the B8 frequency band and the MHB frequency band.

[0070] Referring to Figure 4 , a structural schematic diagram of the matching tuning unit 30 in some other embodiments of the present application is shown. In some other embodiments, as Figure 4 indicated, the number of the cellular matching circuits 31 can be multiple. The cellular communication frequency bands can also be multiple, and each cellular matching circuit 31 corresponds to a cellular communication frequency band. Among them, one cellular matching circuit 31 can be enabled by the first switch unit 33 to make the antenna 20 support the corresponding cellular communication frequency band.

[0071] Exemplarily, as Figure 4 indicated, the cellular communication frequency bands include B5 frequency band, B8 frequency band and MHB frequency band, and the multiple cellular matching circuits 31 are respectively a first cellular matching circuit 31a, a second cellular matching circuit 31b and a third cellular matching circuit 31c, the first cellular matching circuit 31a corresponds to the B5 frequency band, the second cellular matching circuit 31b corresponds to the B8 frequency band, and the third cellular matching circuit 31c corresponds to the MHB frequency band. When the first switch unit 33 selects the first cellular matching circuit 31a to be enabled, the antenna 20 supports the B5 frequency band; when the second cellular matching circuit 31b is selected to be enabled, the antenna 20 supports the B5 frequency band; and when the third cellular matching circuit 31c is selected to be enabled, the antenna 20 supports the MHB frequency band.

[0072] Among them, the matching parameter values presented by the cellular matching circuits 31 and the satellite positioning matching circuit 32 as a whole are different. For example, the matching parameter value presented by each cellular matching circuit 31 as a whole corresponds to the corresponding cellular communication frequency band, and can make the antenna 20 support the corresponding cellular communication frequency band under the matching of the cellular matching circuit 31; the matching parameter value presented by the satellite positioning matching circuit 32 as a whole also corresponds to the corresponding satellite positioning frequency band, and can make the antenna 20 support the corresponding satellite positioning frequency band under the matching of the satellite positioning matching circuit 32.

[0073] Among them, the cellular matching circuit 31 and the satellite positioning matching circuit 32 can be composed of capacitance and / or inductance and / or resistance, and the matching parameter value can include capacitance value and / or inductance value and / or resistance value.

[0074] Among them, the first switch unit 33 can include a single-pole multi-throw switch or multiple matching switches.

[0075] Referring to Figure 5 , a partial circuit structural schematic diagram of the electronic device 100 in some embodiments of the present application is shown. In some embodiments, as Figure 5As shown, the cellular matching circuit 31 comprises a first matching element 34 and a second matching element 35, and the satellite positioning matching circuit 32 comprises the second matching element 35. The first switch unit 33 is connected between the first matching element 34 and the ground GND, the first matching element 34 is connected between the first switch unit 33 and the matching tuning point 21 of the antenna 20, and the second matching element 35 is connected between the matching tuning point 21 and the ground GND.

[0076] The first switch unit 33 is configured to turn on or turn off the electrical connection between the first matching element 34 and the ground GND, so that the cellular matching circuit 31 is enabled to make the matching tuning unit 30 in the first matching state, or the satellite positioning matching circuit 32 is enabled to make the matching tuning unit 30 in the second matching state. That is, when the first switch unit 33 turns on the electrical connection between the first matching element 34 and the ground GND, the cellular matching circuit 31 is enabled, and the matching tuning unit 30 is in the first matching state. When the first switch unit 33 turns off the electrical connection between the first matching element 34 and the ground GND, the satellite positioning matching circuit 32 is enabled, and the matching tuning unit 30 is in the second matching state.

[0077] In some embodiments, the first switch unit 33 is connected between the first matching element 34 and the matching tuning point 21, the first matching element 34 is connected between the first switch unit 33 and the ground GND, and the second matching element 35 is connected between the matching tuning point 21 and the ground GND. When the first switch unit 33 turns on the electrical connection between the first matching element 34 and the matching tuning point 21, the cellular matching circuit 31 is enabled, and the matching tuning unit 30 is in the first matching state. When the first switch unit 33 turns off the electrical connection between the first matching element 34 and the matching tuning point 21, the satellite positioning matching circuit 32 is enabled, and the matching tuning unit 30 is in the second matching state.

[0078] By designing the cellular matching circuit 31 and the satellite positioning matching circuit 32 to share the second matching element 35, the number of elements can be reduced, which helps to reduce the cost.

[0079] In some embodiments, the number of the first matching elements 34 can be multiple, and the multiple first matching elements 34 are connected in parallel between the first switch unit 33 and the matching tuning point 21 or the ground GND, for example as shown in FIG. 2. Figure 5As shown, the plurality of first matching elements 34 are respectively a first frequency band matching element 34a, a second frequency band matching element 34b, and a third frequency band matching element 34c. Each first matching element 34 and the second matching element 35 form a cellular matching circuit 31, for example, the first frequency band matching element 34a and the second matching element 35 form a first cellular matching circuit 31a, the second frequency band matching element 34b and the second matching element 35 form a second cellular matching circuit 31b, and the third frequency band matching element 34c and the second matching element 35 form a third cellular matching circuit 31c. Thus, the matching tuning unit 30 includes a plurality of cellular matching circuits 31, each of which corresponds to a cellular communication frequency band. Among them, one of the cellular matching circuits 31 can be enabled by the first switch unit 33, so that the antenna 20 supports the corresponding cellular communication frequency band. In some other embodiments, the number of first matching elements 34 can be one.

[0080] In some embodiments, the first matching element 34 is a plurality, and the first switch unit 33 can include a single-pole multi-throw switch. Among them, when the first switch unit 33 is connected between the plurality of first matching elements 34 and the ground GND, that is, the first switch unit 33 is located between the plurality of first matching elements 34 and the ground GND (as shown), one end of each first matching element 34 is connected to the matching tuning point 21, the fixed end of the single-pole multi-throw switch is fixedly connected to the ground GND, and the throw end of the single-pole multi-throw switch is used to selectively connect to the other end of one of the first matching elements 34, to establish an electrical connection between the one of the first matching elements 34 and the ground GND, so that the corresponding cellular matching circuit 31 is enabled, so that the antenna 20 supports the corresponding cellular communication frequency band; or, disconnect the connection between the plurality of first matching elements 34 and the ground GND, so that the satellite positioning matching circuit 32 is enabled, so that the antenna 20 supports the satellite positioning frequency band.

[0082] In some embodiments, the first matching element 34 is a plurality of, and the first switch unit 33 can include a plurality of matching switches, each of which corresponds to one of the plurality of first matching elements 34. Each matching switch is connected in series with the corresponding first matching element 34, and each matching switch is connected in series with the corresponding first matching element 34 between the matching tuning point 21 and the ground GND. When the first switch unit 33 is connected between the first matching element 34 and the ground GND, each matching switch is connected between the corresponding first matching element 34 and the ground GND, and when the first switch unit 33 is connected between the first matching element 34 and the matching tuning point 21, each matching switch is connected between the corresponding first matching element 34 and the matching tuning point 21. If the matching switch corresponding to a certain first matching element 34 is turned on, the electrical connection between the first matching element 34 and the matching tuning point 21 and the ground GND is turned on, and the corresponding cellular matching circuit 31 is enabled, so that the antenna 20 supports the corresponding cellular communication frequency band. If the plurality of matching switches are disconnected, the satellite positioning matching circuit 32 is enabled, so that the antenna 20 supports the satellite positioning frequency band.

[0083] In some embodiments, the first matching element 34 and the second matching element 35 can be composed of capacitors and / or inductors and / or resistors.

[0084] In some embodiments, the first switch unit 33 includes a cellular radio frequency port electrically connected to the cellular matching circuit 31, and the cellular radio frequency port is electrically connected to the cellular matching circuit 31. The cellular radio frequency port can be one or more.

[0085] In some embodiments, the cellular radio frequency port of the first switch unit 33 is a plurality of, and each cellular radio frequency port is electrically connected to a cellular matching circuit 31. For example, as shown in FIG. 2, the first switch unit 33 includes a plurality of cellular radio frequency ports 331, and each cellular radio frequency port 331 is electrically connected to a corresponding cellular matching circuit 31.Figure 5 As shown, the first switch unit 33 includes a first cellular radio frequency port RF11, a second cellular radio frequency port RF12, a third cellular radio frequency port RF13, which are electrically connected with a first frequency band matching element 34a, a second frequency band matching element 34b and a third frequency band matching element 34c respectively, and are electrically connected with a first cellular matching circuit 31a, a second cellular matching circuit 31b and a third cellular matching circuit 31c respectively.

[0086] Please refer to Figure 6 , which is a schematic diagram of part of the circuit structure of the electronic device 100 in some embodiments of the present application. In some embodiments, as shown in Figure 6 As shown, the first switch unit 33 is connected between the cellular matching circuit 31 and the satellite positioning matching circuit 32 and the ground, and the cellular matching circuit 31 and the satellite positioning matching circuit 32 are connected in parallel between the first switch unit 33 and the matching tuning point 21 of the antenna 20. Wherein, the matching tuning point 21 can be regarded as a common point.

[0087] Wherein, the first switch unit 33 is used to selectively turn on the electrical connection between the cellular matching circuit 31 and the ground GND or the electrical connection between the satellite positioning matching circuit 32 and the ground GND, so that the cellular matching circuit 31 is enabled, so that the matching tuning unit 30 is in the first matching state, or the satellite positioning matching circuit 32 is enabled, so that the matching tuning unit 30 is in the second matching state.

Wherein, when the first switch unit 33 turns on the electrical connection between the cellular matching circuit 31 and the matching tuning point 21, the cellular matching circuit 31 is enabled, and the matching tuning unit 30 is in the first matching state. When the first switch unit 33 turns on the electrical connection between the satellite positioning matching circuit 32 and the matching tuning point 21, the satellite positioning matching circuit 32 is enabled, and the matching tuning unit 30 is in the second matching state.

[0089] The cellular matching circuit 31 and the satellite positioning matching circuit 32 are connected in parallel, and each matching circuit corresponds to a frequency band independently, so that the matching optimization can be performed independently for each frequency band, and the matching design difficulty is reduced. In addition, the parallel structure also helps to reduce signal interference and improve communication performance.

[0090] In some embodiments, the first switch unit 33 can include a single-pole multi-throw switch for establishing electrical connection between the cellular matching circuit 31 or the satellite positioning matching circuit 32 and the matching tuning point 21 and the ground GND. When the first switch unit 33 is connected between the cellular matching circuit 31 and the satellite positioning matching circuit 32 and the ground GND (as shown), one end of the cellular matching circuit 31 and the satellite positioning matching circuit 32 is connected to the matching tuning point 21, the fixed end of the single-pole multi-throw switch is fixedly connected to the ground GND, and the throw end of the single-pole multi-throw switch can be selectively connected to the other end of the cellular matching circuit 31 or the other end of the satellite positioning matching circuit 32, to establish electrical connection between the cellular matching circuit 31 and the ground GND, so that the cellular matching circuit 31 is enabled, or to establish electrical connection between the satellite positioning matching circuit 32 and the ground GND, so that the satellite positioning matching circuit 32 is enabled. Figure 6 When the first switch unit 33 is connected between the matching tuning point 21 and the cellular matching circuit 31 and the satellite positioning matching circuit 32, one end of the cellular matching circuit 31 and the satellite positioning matching circuit 32 is connected to the ground GND, the fixed end of the single-pole multi-throw switch is fixedly connected to the matching tuning point 21, and the throw end of the single-pole multi-throw switch can be selectively connected to the other end of the cellular matching circuit 31 or the other end of the satellite positioning matching circuit 32.

[0091] In some embodiments, the cellular matching circuit 31 can be multiple, and the multiple cellular matching circuits 31 are connected in parallel between the first switch unit 33 and the matching tuning point 21 or the ground GND, for example, as shown, the multiple cellular matching circuits 31 are respectively a first cellular matching circuit 31a, a second cellular matching circuit 31b, and a third cellular matching circuit 31c, and the throw end can be used to selectively connect to the other end of one of the cellular matching circuits 31, so that the one of the cellular matching circuits 31 is enabled, so that the antenna 20 supports the corresponding cellular communication frequency band. In other embodiments, the number of cellular matching circuits 31 can be one.

[0092] In some embodiments, the cellular matching circuit 31 can be multiple, and the multiple cellular matching circuits 31 are connected in parallel between the first switch unit 33 and the matching tuning point 21 or the ground GND, for example, as shown, the multiple cellular matching circuits 31 are respectively a first cellular matching circuit 31a, a second cellular matching circuit 31b, and a third cellular matching circuit 31c, and the throw end can be used to selectively connect to the other end of one of the cellular matching circuits 31, so that the one of the cellular matching circuits 31 is enabled, so that the antenna 20 supports the corresponding cellular communication frequency band. In other embodiments, the number of cellular matching circuits 31 can be one. Figure 6

[0093] ​In other embodiments, the first switch unit 33 may include multiple matching switches, there is at least one cellular matching circuit 31, and the multiple matching switches correspond one-to-one to at least one cellular matching circuit 31 and the satellite positioning matching circuit 32, wherein each cellular matching circuit 31 corresponds to one matching switch, and each satellite positioning matching circuit 32 corresponds to one matching switch, each matching switch is connected in series with the corresponding matching circuit, and each matching switch and the corresponding matching circuit are connected in series between the matching tuning point 21 and ground GND. When the first switch unit 33 is connected between the matching circuit and ground GND, each matching switch is connected between the corresponding matching circuit and ground GND. When the first switch unit 33 is connected between the matching circuit and the matching tuning point 21, each matching switch is connected between the corresponding matching circuit and the matching tuning point 21. Among them, if the matching switch corresponding to a matching circuit is turned on, the electrical connection between the matching circuit and the matching tuning point 21 and the ground GND is turned on, and the corresponding matching circuit is enabled, so that the antenna 20 supports the corresponding frequency band. For example, the matching switch corresponding to the cellular matching circuit 31 of the B5 band is turned on, so that the antenna supports the B5 band; the matching switch corresponding to the satellite positioning matching circuit 32 of the GPS L1 band is turned on, so that the antenna supports the GPS L1 band.

[0094] In some embodiments, Figure 5 and Figure 6 As shown, the electronic device 100 further includes a combiner 50, which is connected between the cellular communication module 10, the satellite positioning module 40, and the antenna 20. The combiner 50 includes a first port and multiple second ports. The first port of the combiner 50 is connected to the antenna 20. Specifically, the first port is connected to the matching tuning point 21, and the multiple second ports are respectively connected to the cellular communication module 10 and the satellite positioning module 40. The cellular communication module 10 and the satellite positioning module 40 can share the antenna 20 through the combiner 50.

[0095] One of the second ports in the plurality of second ports is connected to a first radio frequency front end module 13 of the cellular communication module 10, and another second port is connected to a second radio frequency front end module 43 of the satellite positioning module 40. When the cellular matching circuit 31 is enabled, the combiner 50 is configured to distribute signals received by the antenna 20 to the first radio frequency front end module 13, and configured to transmit signals output by the first radio frequency front end module 13 to the antenna 20. When the satellite positioning matching circuit 32 is enabled, the combiner 50 is configured to distribute signals received by the antenna 20 to the second radio frequency front end module 43, and configured to transmit signals output by the second radio frequency front end module 43 to the antenna 20.

[0096] Referring to Figure 7 , Fig. 2 shows a schematic diagram of part of the circuit structure of the electronic device 100 according to some embodiments of the present application. In some embodiments, as shown in Fig. 2, the cellular matching circuit 31 and the satellite positioning matching circuit 32 are connected in parallel between the first switch unit 33 and the ground GND, and the first switch unit 33 is connected between the cellular matching circuit 31 and the satellite positioning matching circuit 32 and the matching tuning point 21. Figure 7

[0097] In some embodiments, the cellular matching circuit 31 and the satellite positioning matching circuit 32 are connected in parallel between the first switch unit 33 and the matching tuning point 21.

[0098] In some embodiments, the cellular matching circuit 31 and the satellite positioning matching circuit 32 are connected in parallel between the first switch unit 33 and the matching tuning point 21.

[0099] In some embodiments, as shown in Fig. 2, the cellular matching circuit 31 is connected between the first radio frequency front end module 13 and the first switch unit 33, and the satellite positioning matching circuit 32 is connected between the second radio frequency front end module 43 and the first switch unit 33. Figure 7 In some embodiments, as shown in Fig. 2, the cellular matching circuit 31 is connected between the first radio frequency front end module 13 and the first switch unit 33, and the satellite positioning matching circuit 32 is connected between the second radio frequency front end module 43 and the first switch unit 33.​

[0100] In some embodiments, the cellular matching circuit 31 is a plurality of cellular matching circuits 31 connected in parallel between the first RF front-end module 13 and the first switch unit 33, for example as shown in Figure 7 Figure 2. The plurality of cellular matching circuits 31 are respectively a first cellular matching circuit 31a, a second cellular matching circuit 31b, and a third cellular matching circuit 31c. In other embodiments, the cellular matching circuit 31 is one.

[0101] Each matching circuit corresponds to one frequency band independently. This design allows matching optimization for each frequency band independently, reducing the difficulty of matching design.

[0102] In some embodiments, the first switch unit 33 can include a single-pole multi-throw switch for selecting the cellular matching circuit 31 or the satellite positioning matching circuit 32 to be connected in series in the feed path of the antenna 20. When the first switch unit 33 is connected between the cellular matching circuit 31 and the satellite positioning matching circuit 32 and the matching tuning point 21 (as shown in Figure 7 Figure 2), one end of the cellular matching circuit 31 and the satellite positioning matching circuit 32 is connected to the first RF front-end module 13 and the second RF front-end module 43 respectively, the fixed end of the single-pole multi-throw switch is fixedly connected to the matching tuning point 21, and the throw end of the single-pole multi-throw switch can be selectively connected to the other end of the cellular matching circuit 31 or the other end of the satellite positioning matching circuit 32 to establish electrical connection between the cellular matching circuit 31 and the matching tuning point 21, enabling the cellular matching circuit 31, or to establish electrical connection between the satellite positioning matching circuit 32 and the matching tuning point 21, enabling the satellite positioning matching circuit 32.

[0103] If the cellular matching circuit 31 is a plurality of cellular matching circuits 31, the throw end can be used to selectively connect to the other end of one of the cellular matching circuits 31, enabling the one of the cellular matching circuits 31, so that the antenna 20 supports the corresponding cellular communication frequency band.

[0104] In some embodiments, as shown in

[0105] In some embodiments, as shown in Figure 6 and Figure 7 In some embodiments, as shown in

[0106] In some embodiments, as shown in Figure 6 and Figure 7 In some embodiments, as shown in

[0107] In some embodiments, the electronic device 100 further comprises a power supply module, which supplies power to the cellular communication module 10, the satellite positioning module 40, and the first switch unit 33.

[0108] In some embodiments, as shown in Figure 5 In some embodiments, the cellular communication module 10 is configured to control the power supply module 60 to supply power to the first switch unit 33 in the matching tuning unit 30. The cellular communication module 10 is further configured to control the first switch unit 33 to select the satellite positioning matching circuit 32 to be enabled before entering the non-working state, so that the matching tuning unit 30 is in the second matching state.

[0109] Thus, the power module 60 can only supply power to the first switch unit 33 through the cellular communication module 10, and the matching state of the matching tuning unit 30 can only be controlled through the cellular communication module 10, thereby simplifying the circuit structure of the cellular communication and satellite positioning integrated system and reducing the hardware complexity.

[0110] When the cellular communication module 10 is in a non-working state, i.e., the cellular communication module 10 is powered off or hibernates, the first switch unit 33 cannot continue to be supplied with power, and thus the cellular communication module 10 controls the first switch unit 33 to select the satellite positioning matching circuit 32 to enable before entering the non-working state, so that the matching tuning unit 30 can be stably in the second matching state.

[0111] In some other embodiments, as shown in Figure 6 and Figure 7 The satellite positioning module 40 and the cellular communication module 10 are used together to control the power module 60 to supply power to or not to supply power to the first switch unit 33 in the matching tuning unit 30, and are used together to control the first switch unit 33 in the matching tuning unit 30 to select the cellular matching circuit 31 or the satellite positioning matching circuit 32 to enable, so that the matching tuning unit 30 is in the first matching state or the second matching state.

[0112] Through the common control of the satellite positioning module 40 and the cellular communication module 10, the limitations of single-module control can be avoided, and the system reliability can also be improved. For example, when one of the modules is in a non-working state or is abnormal, the other module can be used to control the power module 60 and the first switch unit 33, to ensure that the first switch unit 33 continuously and stably works, and to ensure that the matching state of the matching tuning unit 30 meets the communication requirements. Thus, the matching tuning unit 30 can be controlled to be in the second matching state at the moment when the cellular communication module 10 enters the non-working state or before or after the moment.

[0113] When the cellular communication module 10 is in a normal working state and / or the satellite positioning module 40 is in a normal working state, the satellite positioning module 40 and the cellular communication module 10 control the power module 60 to supply power to the first switch unit 33. That is, as long as one of the cellular communication module 10 and the satellite positioning module 40 is in a normal working state, the power module 60 can supply power to the first switch unit 33. Thus, when one of the cellular communication module 10 and the satellite positioning module 40 is in a non-working state, the other one can control the power module 60 to supply power to the first switch unit 33, thereby avoiding the problem that the matching tuning unit 30 can not be in a required matching state due to one of the cellular communication module 10 and the satellite positioning module 40 being in a non-working state.

[0114] When the cellular matching circuit 31 and the satellite positioning matching circuit 32 are connected between the first switch unit 33 and the matching tuning point 21 or the ground, if the first switch unit 33 is supplied with power only by the cellular communication module 10, when the cellular communication module 10 is in a non-working state, the power module 60 does not supply power to the first switch unit 33, which can cause the state of the first switch unit 33 to be unstable, for example, other paths can be switched on. In the embodiment of the present application, when either of the cellular communication module 10 and the satellite positioning module 40 is in a normal working state, the power module 60 can supply power to the first switch unit 33, thereby ensuring that the first switch unit 33 can remain in a normal working state when one of the modules enters a non-working state, and making the matching tuning unit 30 be in a stable required matching state.

[0115] When the cellular communication module 10 is in a non-working state, for example, powered off or hibernation, and the satellite positioning module 40 is in a normal working state, the power module 60 supplies power to the first switch unit 33. When the satellite positioning module 40 is in a non-working state and the cellular communication module 10 is in a normal working state, the power module 60 supplies power to the first switch unit 33, wherein the non-working state of the satellite positioning module 40 can be that the satellite positioning module 40 is powered off or hibernation. When the cellular communication module 10 and the satellite positioning module 40 are both in a normal working state, the power module 60 supplies power to the first switch unit 33.

[0116] The matching tuning unit 30 can be controlled to be in the second matching state before or after the cellular communication module 10 enters a non-working state.

[0117] When the cellular communication module 10 is in a non-working state and the satellite positioning module 40 is in a non-working state, the power module 60 does not supply power to the first switch unit 33.

[0118] wherein, as shown in Figure 6 and Figure 7 the satellite positioning module 40 and the cellular communication module 10 are collectively configured to control the power module 60 to power or not power the first switch unit 33 in the matching tuning unit 30 and to control the first switch unit 33 in the matching tuning unit 30 to select the cellular matching circuit 31 or the satellite positioning matching circuit 32 to be enabled, including that the first modem 11 and the second modem 41 are collectively configured to control the power module 60 to power or not power the first switch unit 33 in the matching tuning unit 30 and to control the first switch unit 33 in the matching tuning unit 30 to select the cellular matching circuit 31 or the satellite positioning matching circuit 32 to be enabled.

[0119] In some embodiments, as shown in Figure 6 and Figure 7 the electronic device 100 further comprises a first logic circuit 90 connected between the cellular communication module 10, the satellite positioning module 40 and the first switch unit 33, the cellular communication module 10 and the satellite positioning module 40 are configured to output a first switch control signal and a second switch control signal respectively, and the first logic circuit 90 is configured to convert switch logic for controlling the first switch unit 33 according to the first switch control signal and the second switch control signal to control the first switch unit 33 to select the cellular matching circuit 31 or the satellite positioning matching circuit 32 to be enabled, thereby controlling the matching tuning unit 30 to be in the first matching state or the second matching state.

[0120] The first logic circuit 90 can intelligently manage the cellular communication and satellite positioning functions, i.e. automatically switch the matching state of the matching tuning unit 30 according to the working state of the cellular communication module 10.

[0121] wherein, the first logic circuit 90 is configured to generate a third switch control signal and a fourth switch control signal according to the first switch control signal and the second switch control signal, and output the third switch control signal and the fourth switch control signal to the first switch unit 33 to control the first switch unit 33 to select the cellular matching circuit 31 or the satellite positioning matching circuit 32 to be enabled.

[0122] Exemplarily, the correspondence between the third switch control signal and the fourth switch control signal and the matching state of the matching tuning unit 30 and the frequency band supported by the antenna 20 can be as shown in Table 1.

[0123] Table 1

[0124]

[0125] In some embodiments, the number of the cellular matching circuits 31 is multiple, the first switch control signal includes multiple sub-switch control signals, and the first logic circuit 90 is configured to generate the third switch control signal and the fourth switch control signal according to the multiple sub-switch control signals and the second switch control signal.

[0126] For example, as shown in FIGS. 1, 2 and 3, the first switch control signal output by the cellular communication module 10 includes multiple sub-switch control signals, such as an enable signal EN, a first line control signal IO1, and a second line control signal IO2, the second switch control signal IO3 is output by the satellite positioning module 40, and the first logic circuit 90 generates the third switch control signal GPIO1 and the fourth switch control signal GPIO2. Figure 6 and Figure 7 For example, as shown in FIGS. 1, 2 and 3, the first switch control signal output by the cellular communication module 10 includes multiple sub-switch control signals, such as an enable signal EN, a first line control signal IO1, and a second line control signal IO2, the second switch control signal IO3 is output by the satellite positioning module 40, and the first logic circuit 90 generates the third switch control signal GPIO1 and the fourth switch control signal GPIO2.

[0127] For example, as shown in FIGS. 1, 2 and 3, the first switch control signal output by the cellular communication module 10 includes multiple sub-switch control signals, such as an enable signal EN, a first line control signal IO1, and a second line control signal IO2, the second switch control signal IO3 is output by the satellite positioning module 40, and the first logic circuit 90 generates the third switch control signal GPIO1 and the fourth switch control signal GPIO2.

[0128] For example, as shown in FIGS. 1, 2 and 3, the first switch control signal output by the cellular communication module 10 includes multiple sub-switch control signals, such as an enable signal EN, a first line control signal IO1, and a second line control signal IO2, the second switch control signal IO3 is output by the satellite positioning module 40, and the first logic circuit 90 generates the third switch control signal GPIO1 and the fourth switch control signal GPIO2.

[0129] Table 2

[0130]

[0131] Wherein, X can be 0 or 1. Since the enable signal EN is 0, it represents that the cellular communication module 10 is in a non-working state, i.e. the cellular communication module 10 does not work, then no matter the first and second line control signals IO1 and IO2 are 0 or 1, the third and fourth switch control signals GPIO1 and GPIO2 are 1, so that the matching tuning unit 30 is in the second matching state, and the antenna 20 supports the satellite positioning frequency band.

[0132] Table 3

[0133]

[0134] Wherein, the sub-switch control signal of the first control signal can be configured according to the number of cellular communication frequency bands, for example, increasing or decreasing the line control signal. By increasing or decreasing the line control signal, and adjusting the switch logic of the first logic circuit 90, the number of cellular communication frequency bands supported by the antenna 20 can be adjusted.

[0135] In some embodiments, as shown in Figure 6 and Figure 7 The electronic device 100 further includes a second logic circuit 80 connected between the cellular communication module 10, the satellite positioning module 40 and the power supply module 60, the cellular communication module 10 and the satellite positioning module 40 are used to output first and second power control signals IO5 and IO4 respectively, the second logic circuit 80 is used to generate a third power control signal GPIO3 according to the first and second power control signals IO5 and IO4, and the power supply module 60 supplies power or does not supply power to the first switch unit 33 based on the third power control signal GPIO3.

[0136] The second logic circuit 80 as an intermediate control layer can make logical judgment according to the control signals of the cellular communication module 10 and the satellite positioning module 40 to control whether the power supply module 60 supplies power to the first switch unit 33. Such design helps to avoid the problem of unstable power supply caused by misoperation or signal interference, and improves the stability and reliability of the control system.

[0137] Exemplarily, the first power control signal IO5 outputted by the cellular communication module 10 is 1 when the cellular communication module 10 is in the normal working state, and is 0 when the cellular communication module 10 is in the non-working state; the second power control signal IO4 outputted by the satellite positioning module 40 is 1 when the satellite positioning module 40 is in the normal working state, and is 0 when the satellite positioning module 40 is in the non-working state. The corresponding relationship between the first power control signal IO5, the second power control signal IO4, the third power control signal GPIO3 and whether the power module 60 supplies power to the first switch unit 33 can be shown in Table 4.

[0138] Table 4

[0139]

[0140] In some embodiments, the matching tuning unit 30 is in the first matching state when the cellular communication module 10 is in the normal working state, and is in the second matching state when the cellular communication module 10 is in the non-working state.

[0141] In some embodiments, the matching tuning unit 30 is in the first matching state when the cellular communication module 10 is in the normal working state and the satellite positioning module 40 is in the non-working state.
