Description

Technical Field

[0001] This 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 Art

[0002] With the rapid development of mobile communication technology, terminal devices with cellular functions have become necessities in people's daily lives. At the same time, with the wide application of satellite positioning technology, terminal devices supporting satellite positioning have also attracted increasing attention. Currently, due to size limitations and narrow bezel designs, terminal devices with cellular and satellite positioning functions on the market usually integrate the cellular and satellite positioning functions into a single antenna structure. However, this will cause the antenna performance not to be fully utilized, affecting communication quality. Summary of the Invention

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

[0004] In a first aspect of this application, an electronic device is provided. The electronic device includes a cellular communication module, an antenna, and a matching and tuning unit. The antenna includes a matching and tuning point, and the matching and tuning unit is connected to the matching and tuning point of the antenna. The matching and tuning unit includes a first matching state and a second matching state. Among them, when the matching and tuning unit is in the first matching state, the antenna supports the cellular communication band, and when the matching and tuning unit is in the second matching state, the antenna supports the satellite positioning band. Among them, after the cellular communication module enters the non-working state, the matching and tuning unit is in the second matching state, so that the antenna supports the satellite positioning band.

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

[0006] In a possible implementation, the matching and tuning unit includes a cellular matching circuit, a satellite positioning matching circuit, and a first switching unit. The first switching unit is used to select the cellular matching circuit or the satellite positioning matching circuit to be enabled, so that the matching and 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 and gated by the first switching unit, so that the antenna can support different communication frequency bands under different communication requirements and can provide better signal receiving and transmitting performance.

[0007] In a possible implementation, the first switching unit is connected between the cellular matching circuit, the satellite positioning matching circuit and the ground. The cellular matching circuit and the satellite positioning matching circuit are connected in parallel between the first switching unit and the matching tuning point. The first switching unit is used to selectively conduct 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 and tuning unit in the first matching state, or the satellite positioning matching circuit is enabled to make the matching and 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 independently corresponds to a frequency band. Such a design enables independent matching optimization for each frequency band, reducing the difficulty of matching design. In addition, the parallel structure helps to reduce signal interference and improve communication performance.

[0009] In a possible implementation, the cellular matching circuit includes a first matching element and a second matching element. The satellite positioning matching circuit includes the second matching element. The first switching unit is connected between the first matching element and the ground. The first matching element is connected between the first switching unit and the matching tuning point. The second matching element is connected between the matching tuning point and the ground. The first switching unit is used to conduct or disconnect the electrical connection between the first matching element and the ground, so that the cellular matching circuit is enabled to make the matching and tuning unit in the first matching state, or the satellite positioning matching circuit is enabled to make the matching and 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 components can be reduced, which helps to reduce costs.

[0011] In a possible implementation, the cellular matching circuit and the satellite positioning matching circuit are connected in parallel between the first switching unit and the ground, and the first switching unit is connected between the cellular matching circuit and the satellite positioning matching circuit and the matching tuning point; the first switching unit is configured to selectively conduct the electrical connection between the cellular matching circuit and the matching tuning point or the electrical connection between the satellite positioning matching circuit and the matching tuning point, 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.

[0012] Each matching circuit independently corresponds to a frequency band. Such a design enables independent matching optimization for each frequency band, 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. The satellite positioning module and the cellular communication module are jointly configured to control the power supply module to supply power to the first switching unit in the matching tuning unit, and jointly configured to control the first switching unit in the matching tuning unit 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.

[0014] Through the joint control of the satellite positioning module and the cellular communication module, 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 abnormal, the other module can be used to control the power supply and the first switching unit to ensure that the first switching unit works continuously and stably, and to ensure that the matching state of the matching tuning unit meets the communication requirements. Thus, the matching tuning unit can be controlled to be in the second matching state at, before, or after the moment when the cellular communication module enters the non-working state.

[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 switching unit.

[0016] Thus, 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 switching unit, thereby avoiding the problem that the matching tuning unit may not be in the required matching state due to one of them being in a non-working state.

[0017] In a possible implementation, the electronic device further includes a first logic circuit, which is 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 respectively used to output a first switch control signal and a second switch control signal. The first logic circuit is used to convert the first switch control signal and the second switch control signal into a switch logic for controlling the first switch unit, 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] Through the first logic circuit, the cellular communication and satellite positioning functions can be intelligently managed, that is, the matching state of the matching tuning unit is automatically switched according to the working state of the cellular communication module.

[0019] In a possible implementation, the electronic device further includes a power supply module. The cellular communication module is used to control the power supply module to supply power to the first switch unit, and is used to 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] Thus, 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 integration system and reducing the hardware complexity.

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

[0022] When the cellular communication module enters the sleep state, cellular communication is not required. At this time, by controlling the matching tuning unit to be in the second matching state, the antenna supports the satellite positioning frequency band, which can effectively utilize the antenna, improve the utilization rate of the antenna, and meet the positioning requirements.

[0023] In a possible implementation, the electronic device further includes a controller and a satellite positioning module. The controller is used 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] Therefore, the controller can manage and coordinate the control of the first switching 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 the flight mode; the electronic device establishes a communication connection with the terminal and the mobile communication unit of the terminal works normally; the electronic device does not activate the identification 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. Thus, in the flight mode, the electronic device can effectively use the antenna for satellite positioning, and can ensure that the antenna performance of satellite positioning is fully exerted, and further can improve the accuracy of the satellite positioning trajectory.

[0027] Among them, when the electronic device is communicatively connected to the terminal, it can be considered that cellular communication is not required 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. Thus, when the electronic device is communicatively connected to other devices, the electronic device can effectively use the antenna for satellite positioning, and can ensure that the antenna performance of satellite positioning is fully exerted, and further can improve the accuracy of the satellite positioning trajectory. The communication connection between the electronic device and the terminal may include the electronic device being Bluetooth-connected or Wifi-connected or wired-connected to the terminal.

[0028] Among them, if the electronic device does not activate the identification card, for example, the identification card is not inserted into the electronic device or the identification card is not set, or the electronic device is equipped with the identification card but it does not work, it means 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. Thus, in the case of not activating the identification card, the electronic device can effectively use the antenna for satellite positioning, and can ensure that the antenna performance of satellite positioning is fully exerted, and further can improve the accuracy of the satellite positioning trajectory.

[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 powered-off state or a sleep state.

[0031] In a possible implementation, after the cellular communication module enters the normal working state, the matching tuning unit is in the first matching state, so that the antenna supports the cellular communication frequency band. Thus, not only can cellular communication be performed when the cellular communication module is working properly, but also the antenna performance of 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. Thus, not only the utilization rate of the antenna is improved, but also the corresponding communication functions can be supported under different communication requirements, such as cellular communication requirements and satellite positioning requirements, effectively supporting multiple communication functions and realizing the coexistence of the cellular communication function and the satellite positioning function.

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

[0033] The communication control method provided in the above second aspect is applied to the electronic device provided in the first aspect, so it can achieve the same or corresponding beneficial effects as the electronic device provided in the first aspect, and will not be elaborated here.

[0034] A third aspect of the present application provides a computer-readable storage medium, in which a computer program is stored, and the computer program is used to be called by a processor and executed to implement the communication control method provided in the second aspect.

[0035] The computer-readable storage medium provided in the above third aspect is used to implement the communication control method provided in the above second aspect, so it can achieve the same or corresponding beneficial effects as the communication control method provided in the second aspect, and will not be elaborated here.

The display of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

[0056] Please refer to Figure 1 , which is a schematic structural diagram of the electronic device 100 in some embodiments of the present application. In some embodiments, such asFigure 1 As shown, the electronic device 100 includes a cellular communication module 10, an antenna 20, and a matching and tuning unit 30. The antenna 20 includes a matching and tuning point 21, and the matching and tuning unit 30 is connected to the matching and tuning point 21 of the antenna 20. The matching and tuning unit 30 includes a first matching state and a second matching state. When the matching and tuning unit 30 is in the first matching state, the antenna 20 supports the cellular communication band. When the matching and tuning unit 30 is in the second matching state, the antenna 20 supports the satellite positioning band. Wherein, after the cellular communication module 10 enters the non-operating state, the matching and tuning unit 30 is in the second matching state, so that the antenna 20 supports the satellite positioning band.

[0057] The electronic device 100 provided in this application includes a matching and tuning unit 30, which has a first matching state and a second matching state, corresponding to the cellular communication band and the satellite positioning band respectively. Thus, by switching the matching state of the matching and tuning unit 30, the antenna 20 can support different communication bands. Wherein, when the cellular communication module 10 is in the non-operating state, the matching and tuning unit 30 will switch to the second matching state, so that the antenna 20 supports the satellite positioning band. Thus, not only can satellite positioning be performed when the cellular communication module 10 is not working, but also the antenna performance of satellite positioning can be fully exerted to ensure the communication quality of satellite positioning.

[0058] Wherein, the cellular communication band may include at least one of a low-frequency (LB) band, a medium-frequency (MB) band, and a high-frequency (HB) band. For example, the cellular communication band includes one or more of the B5 band, the B8 band, and the MHB band. The satellite positioning band may include one or more of GPS L1 and GPS L5.

[0059] In some embodiments, after the cellular communication module 10 enters the normal operating state, the matching and tuning unit 30 is in the first matching state, so that the antenna 20 supports the cellular communication band. Wherein, the non-operating state of the cellular communication module 10 may be the state other than its normal operating state.

[0060] Thus, not only can cellular communication be performed when the cellular communication module 10 is operating normally, but also the antenna performance of cellular communication can be fully utilized, thereby ensuring the quality of cellular communication. By adjusting the matching state of the matching and tuning unit 30 according to the operating state of the cellular communication module 10, the antenna 20 can support the cellular communication frequency band and the satellite positioning frequency band respectively. Thus, not only is the utilization rate of the antenna increased, but also the corresponding communication functions can be supported under different communication requirements, such as cellular communication requirements and satellite positioning requirements, effectively supporting multiple communication functions and realizing the coexistence of the cellular communication function and the satellite positioning function.

[0061] Please further refer to Figure 2 , Figure 2 which is a schematic structural diagram of an electronic device in some other embodiments of the present application. In some embodiments, as Figure 2 shown, the cellular communication module 10 includes a first modem 11, a first radio frequency integrated circuit (RFIC) 12, and a first radio frequency front-end module 13. The first radio frequency integrated circuit 12 is connected between the first modem 11 and the first radio frequency front-end module 13. The first modem 11 is used for converting between analog signals and digital signals. The first radio frequency integrated circuit 12 is used for converting the digital signals of the first modem 11 and radio frequency signals. The first radio frequency front-end module 13 is used for processing radio frequency signals, such as filtering, amplifying, separating transmitted and received signals, etc. The first radio frequency integrated circuit 12 may include electronic devices such as mixers and local oscillators. The first radio frequency front-end module 13 may include electronic devices such as filters, low-noise amplifiers, power amplifiers, and duplexers.

[0062] Among them, when the cellular communication module 10 is in a non-operating state, it may include that the first modem 11 is in a non-operating state. When the cellular communication module 10 is in a normal operating state, it may include that the first modem 11 is in a normal operating state.

[0063] In some embodiments, the non-operating state of the cellular communication module 10 is a powered-off state or a sleep state. Among them, when the cellular communication module 10 is in a powered-off state or a sleep state, it may include that the first modem 11 is in a powered-off state or a sleep state. Therefore, in some embodiments, the cellular communication module 10 may also only include the first modem 11.

[0064] In some embodiments, as Figure 2As shown, the electronic device 100 further includes a satellite positioning module 40, which includes a second modem 41, a second radio frequency integrated circuit (RFIC) 42, and a second radio frequency front-end module 43. The second RFIC 42 is connected between the second modem 41 and the second radio frequency front-end module 43. The second modem 41 is used for converting between analog signals and digital signals. The second RFIC 42 is used for converting the digital signals of the second modem 41 and radio frequency signals. The second radio frequency front-end module 43 is used for processing radio frequency signals, such as filtering, amplifying, separating transmitted and received signals, etc. The second RFIC 42 may include electronic devices such as mixers and local oscillators. The second radio frequency front-end module 43 may include electronic devices such as filters, low-noise amplifiers, power amplifiers, and duplexers.

[0065] In some embodiments, the non-operating state of the satellite positioning module 40 is a powered-off state or a sleep state. Among them, the satellite positioning module 40 being in the powered-off state or the sleep state may include the second modem 41 being in the powered-off state or the sleep state. Therefore, in some embodiments, the satellite positioning module 40 may also only include the second modem 41.

[0066] Among them, in the subsequent drawings, the cellular communication module 10 including a first modem 11, a first RFIC 12, and a first radio frequency front-end module 13, and the satellite positioning module 40 including a second modem 41, a second RFIC 42, and a second radio frequency front-end module 43 are taken as examples for illustration.

[0067] Please refer to Figure 3 , which is a schematic structural diagram of the matching tuning unit 30 in some embodiments of the present application. In some embodiments, as Figure 3 shown, the matching tuning unit 30 includes a cellular matching circuit 31, a satellite positioning matching circuit 32, and a first switch unit 33. The first switch unit 33 is used 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. Thus, the cellular matching circuit 31 or the satellite positioning matching circuit 32 can be intelligently selected through the first switch unit 33, so that the antenna 20 can support different communication frequency bands under different communication requirements and can provide better signal reception and transmission performance.

[0068] In some embodiments, as Figure 3 shown, the number of the cellular matching circuits 31 may be one, and the cellular communication frequency band may include one. For example, the cellular communication frequency band is one of the B5 band, the B8 band, and the MHB band.

[0069] Please refer to Figure 4 , which is a schematic structural diagram of the matching tuning unit 30 in some other embodiments of the present application. In some other embodiments, as Figure 4 shown, the number of the cellular matching circuits 31 may be multiple. The cellular communication bands may include multiple bands, and each cellular matching circuit 31 corresponds to a cellular communication band. Among them, one of the cellular matching circuits 31 can be selected by the first switching unit 33 to be enabled, so that the antenna 20 supports the corresponding cellular communication band.

[0070] Exemplarily, as Figure 4 shown, the cellular communication bands include Band B5, Band B8, and MHB band. 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 Band B5, the second cellular matching circuit 31b corresponds to Band B8, and the third cellular matching circuit 31c corresponds to MHB band. When the first switching unit 33 selects the first cellular matching circuit 31a to be enabled, the antenna 20 supports Band B5. When the second cellular matching circuit 31b is selected to be enabled, the antenna 20 supports Band B5. When the third cellular matching circuit 31c is selected to be enabled, the antenna 20 supports MHB band.

[0071] Among them, the matching parameter values presented by the cellular matching circuit 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 band, so that the antenna 20 can support the corresponding cellular communication 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 band, so that the antenna 20 can support the corresponding satellite positioning band under the matching of the satellite positioning matching circuit 32.

[0072] Among them, the cellular matching circuit 31 and the satellite positioning matching circuit 32 may be composed of capacitors and / or inductors and / or resistors, and the matching parameter values may include capacitance values and / or inductance values and / or resistance values.

[0073] Among them, the first switching unit 33 may include a single-pole multi-throw switch or multiple matching switches.

[0074] Please refer to Figure 5 , which is a schematic diagram of a partial circuit structure of the electronic device 100 in some embodiments of the present application. In some embodiments, as Figure 5As shown, the cellular matching circuit 31 includes a first matching element 34 and a second matching element 35, and the satellite positioning matching circuit 32 includes 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. The second matching element 35 is connected between the matching tuning point 21 and the ground GND.

[0075] Wherein, the first switch unit 33 is configured to conduct or disconnect the electrical connection between the first matching element 34 and the ground GND, so that the cellular matching circuit 31 is enabled, and the matching tuning unit 30 is in the first matching state, or the satellite positioning matching circuit 32 is enabled, and the matching tuning unit 30 is in the second matching state. That is, when the first switch unit 33 conducts 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 disconnects 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.

[0076] 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. The second matching element 35 is connected between the matching tuning point 21 and the ground GND. Wherein, when the first switch unit 33 conducts 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 disconnects 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.

[0077] By designing the cellular matching circuit 31 and the satellite positioning matching circuit 32 to share the second matching element 35, the number of components can be reduced, which helps to reduce costs.

[0078] 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, Figure 5As shown, the multiple 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 multiple cellular matching circuits 31, and each cellular matching circuit 31 corresponds to a cellular communication frequency band. Among them, one of the cellular matching circuits 31 can be selected to be enabled through the first switch unit 33, so that the antenna 20 supports the corresponding cellular communication frequency band. In some other embodiments, the number of the first matching elements 34 can be one.

[0079] In some embodiments, the first matching elements 34 are multiple, and the first switch unit 33 may include a single-pole multi-throw switch. Among them, when the first switch unit 33 is connected between the multiple first matching elements 34 and the ground GND, that is, the first switch unit 33 is located between the multiple first matching elements 34 and the ground GND (as Figure 5 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 throwing 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 first matching element 34 and the ground GND, so that the corresponding cellular matching circuit 31 is enabled, and thus the antenna 20 supports the corresponding cellular communication frequency band; or, disconnect the connection between the multiple first matching elements 34 and the ground GND, so that the satellite positioning matching circuit 32 is enabled, and thus the antenna 20 supports the satellite positioning frequency band.

[0080] Wherein, when the first switching unit 33 is connected between the first matching element 34 and the matching tuning point 21, that is, when the first switching unit 33 is located between the matching tuning point 21 and the first matching element 34, one end of the first matching element 34 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 throwing end 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 first matching element 34 and the matching tuning point 21, so that the corresponding cellular matching circuit 31 is enabled, thereby enabling the antenna 20 to support the corresponding cellular communication band; or, disconnect the connection between the plurality of first matching elements 34 and the matching tuning point 21, so that the satellite positioning matching circuit 32 is enabled, thereby enabling the antenna 20 to support the satellite positioning band.

[0081] In some other embodiments, there are a plurality of first matching elements 34, the first switching unit 33 may include a plurality of matching switches, the plurality of matching switches respectively correspond to the plurality of first matching elements 34 one by one, each matching switch is connected in series with the corresponding first matching element 34, and each matching switch and the corresponding first matching element 34 are connected in series between the matching tuning point 21 and the ground GND. Wherein, when the first switching 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 switching 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. Wherein, if the matching switch corresponding to a certain first matching element 34 is turned on, the electrical connection between the first matching element 34, the matching tuning point 21 and the ground GND is turned on, so that the corresponding cellular matching circuit 31 is enabled, thereby enabling the antenna 20 to support the corresponding cellular communication band. If the plurality of matching switches are disconnected, the satellite positioning matching circuit 32 will be enabled, thereby enabling the antenna 20 to support the satellite positioning band.

[0082] Wherein, the first matching element 34 and the second matching element 35 may be composed of capacitors and / or inductors and / or resistors.

[0083] In some embodiments, the first switching 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. Wherein, the cellular radio frequency port may be one or more.

[0084] In some embodiments, there are a plurality of cellular radio frequency ports of the first switching unit 33, and each cellular radio frequency port is electrically connected to a cellular matching circuit 31. For example, asFigure 5 As shown, the first switching unit 33 includes a first cellular radio frequency port RF11, a second cellular radio frequency port RF12, and a third cellular radio frequency port RF13, which are electrically connected to a first band matching element 34a, a second band matching element 34b, and a third band matching element 34c respectively, and are electrically connected to a first cellular matching circuit 31a, a second cellular matching circuit 31b, and a third cellular matching circuit 31c respectively.

[0085] Please refer to Figure 6 , which is a schematic diagram of a partial circuit structure of the electronic device 100 in some other embodiments of the present application. In some embodiments, as Figure 6 shown, the first switching unit 33 is connected between the cellular matching circuit 31 and the satellite positioning matching circuit 32 and the ground. The cellular matching circuit 31 and the satellite positioning matching circuit 32 are connected in parallel between the first switching unit 33 and the matching tuning point 21 of the antenna 20. Among them, the matching tuning point 21 can be regarded as a common point.

[0086] Among them, the first switching unit 33 is used to selectively conduct 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. That is, when the first switching unit 33 conducts the electrical connection between the cellular matching circuit 31 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 switching unit 33 conducts the electrical connection between the satellite positioning matching circuit 32 and the ground GND, the satellite positioning matching circuit 32 is enabled, and the matching tuning unit 30 is in the second matching state.

[0087] In some embodiments, the first switching unit 33 is connected between the cellular matching circuit 31 and the satellite positioning matching circuit 32 and the matching tuning point 21 of the antenna 20. The cellular matching circuit 31 and the satellite positioning matching circuit 32 are connected in parallel between the first switching unit 33 and the ground GND. Among them, when the first switching unit 33 conducts 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 switching unit 33 conducts 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.

[0088] The cellular matching circuit 31 and the satellite positioning matching circuit 32 are connected in parallel, and each matching circuit independently corresponds to a frequency band. Such a design enables independent matching optimization for each frequency band, reducing the difficulty of matching design. In addition, the parallel structure helps to reduce signal interference and improve communication performance.

[0089] Among them, in some embodiments, the first switch unit 33 may include a single-pole multi-throw switch, and the single-pole multi-throw switch is used to establish an 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. Among them, 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 Figure 6 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 throwing 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 an electrical connection between the cellular matching circuit 31 and the ground GND, so that the cellular matching circuit 31 is enabled, or to establish an electrical connection between the satellite positioning matching circuit 32 and the ground GND, so that the satellite positioning matching circuit 32 is enabled.

[0090] Among them, 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 throwing 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, there are multiple cellular matching circuits 31, 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 Figure 6 shown, the multiple cellular matching circuits 31 are respectively the first cellular matching circuit 31a, the second cellular matching circuit 31b, and the third cellular matching circuit 31c. The throwing end can be used to selectively connect to the other end of one of the cellular matching circuits 31, so that the one cellular matching circuit 31 is enabled, thereby enabling the antenna 20 to support the corresponding cellular communication frequency band. In other embodiments, the number of the cellular matching circuits 31 may be one.

[0092] In some other embodiments, the first switch unit 33 may include a plurality of matching switches, there is at least one cellular matching circuit 31, and the plurality of matching switches are respectively in one-to-one correspondence with at least one cellular matching circuit 31 and the satellite positioning matching circuit 32. Among them, each cellular matching circuit 31 corresponds to one matching switch, the 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 the ground GND. Among them, when the first switch unit 33 is connected between the matching circuit and the ground GND, each matching switch is connected between the corresponding matching circuit and the 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 certain matching circuit is turned on, the electrical connection between this matching circuit, the matching tuning point 21, and the ground GND is turned on, so that the corresponding matching circuit is enabled, thereby enabling the antenna 20 to support the corresponding frequency band. For example, when the matching switch corresponding to the cellular matching circuit 31 of the B5 frequency band is turned on, the antenna can support the B5 frequency band; when the matching switch corresponding to the satellite positioning matching circuit 32 of the GPS L1 frequency band is turned on, the antenna can support the GPS L1 frequency band.

[0093] Among them, in some embodiments, as Figure 5 and Figure 6 shown, the electronic device 100 further includes a combiner 50, and the combiner 50 is connected between the cellular communication module 10, the satellite positioning module 40, and the antenna 20. Among them, the combiner 50 includes a first port and a plurality of 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 plurality of 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.

[0094] One of the multiple second ports is connected to the first radio frequency front-end module 13 of the cellular communication module 10, and the other second port is connected to the second radio frequency front-end module 43 of the satellite positioning module 40. When the cellular matching circuit 31 is enabled, the multiplexer 50 is configured to distribute the signals received by the antenna 20 to the first radio frequency front-end module 13, and to transmit the 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 multiplexer 50 is configured to distribute the signals received by the antenna 20 to the second radio frequency front-end module 43, and to transmit the signals output by the second radio frequency front-end module 43 to the antenna 20.

[0095] Please refer to Figure 7 , which is a schematic diagram of a partial circuit structure of the electronic device 100 in some other embodiments of the present application. In some embodiments, as Figure 7 shown, 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.

[0096] Among them, the first switch unit 33 is configured to selectively conduct the electrical connection between the cellular matching circuit 31 and the matching tuning point 21 or the electrical connection between the satellite positioning matching circuit 32 and the matching tuning point 21, 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 conducts 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 conducts 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.

[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] Among them, in some embodiments, as Figure 7 shown, 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.

[0099] In some embodiments, there are multiple cellular matching circuits 31, and the multiple cellular matching circuits 31 are connected in parallel between the first radio frequency front-end module 13 and the first switch unit 33. For example, as Figure 7 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. In other embodiments, there is one cellular matching circuit 31.

[0100] Each matching circuit independently corresponds to a frequency band. Such a design enables independent matching optimization for each frequency band, reducing the difficulty of matching design.

[0101] Among them, in some embodiments, the first switch unit 33 may include a single-pole multi-throw switch, and the single-pole multi-throw switch is used to select the cellular matching circuit 31 or the satellite positioning matching circuit 32 to be connected in series in the feeding path of the antenna 20. Among them, 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 Figure 7 shown), one end of the cellular matching circuit 31 and the satellite positioning matching circuit 32 are respectively connected to the first radio frequency front-end module 13 and the second radio frequency front-end module 43, the fixed end of the single-pole multi-throw switch is fixedly connected to the matching tuning point 21, and the throwing 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 an electrical connection between the cellular matching circuit 31 and the matching tuning point 21, so that the cellular matching circuit 31 is enabled, or to establish an electrical connection between the satellite positioning matching circuit 32 and the matching tuning point 21, so that the satellite positioning matching circuit 32 is enabled.

[0102] If there are multiple cellular matching circuits 31, the throwing end can be used to selectively connect to the other end of one of the cellular matching circuits 31, so that the one cellular matching circuit 31 is enabled, thereby enabling the antenna 20 to support the corresponding cellular communication frequency band.

[0103] In some other embodiments, the first switch unit 33 may include a plurality of matching switches, there is at least one cellular matching circuit 31, and the plurality of matching switches respectively correspond to at least one cellular matching circuit 31 and the satellite positioning matching circuit 32 one by one. Among them, each cellular matching circuit 31 corresponds to one matching switch, the 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 corresponding radio frequency front-end module and the matching tuning point 21. For example, the cellular matching circuit 31 and the corresponding matching switch are connected in series between the first radio frequency front-end module 13 and the matching tuning point 21. Among them, if the matching switch corresponding to a certain matching circuit is turned on, the electrical connection between this matching circuit and the matching tuning point 21 is turned on, so that the corresponding matching circuit is enabled, thereby enabling the antenna 20 to support the corresponding frequency band. For example, when the matching switch corresponding to the cellular matching circuit 31 of the B5 frequency band is turned on, the antenna can support the B5 frequency band; when the matching switch corresponding to the satellite positioning matching circuit 32 of the GPS L1 frequency band is turned on, the antenna can support the GPS L1 frequency band.

[0104] In some embodiments, such as Figure 6 and Figure 7 shown, the first switch unit 33 includes a satellite positioning radio frequency port RF2 electrically connected to the satellite positioning matching circuit 32, and the satellite positioning radio frequency port RF2 is electrically connected to the satellite positioning matching circuit 32. Among them, the satellite positioning radio frequency port RF2 can be one or more.

[0105] In some embodiments, such as Figure 6 and Figure 7 shown, the first cellular radio frequency port RF11, the second cellular radio frequency port RF12, and the third cellular radio frequency port RF13 are respectively electrically connected to the first cellular matching circuit 31a, the second cellular matching circuit 31b, and the third cellular matching circuit 31c.

[0106] In some embodiments, the electronic device 100 further includes a power module, and the power module supplies power to the cellular communication module 10, the satellite positioning module 40, and the first switch unit 33.

[0107] In some embodiments, such as Figure 5 shown, the cellular communication module 10 is used to control the power module 60 to supply power to the first switch unit 33 in the matching tuning unit 30. The cellular communication module 10 is further used 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.

[0108] Therefore, the power supply module 60 can be controlled by the cellular communication module 10 alone to supply power to the first switching unit 33, and the matching state of the matching and tuning unit 30 can be controlled by the cellular communication module 10 alone, thereby simplifying the circuit structure of the cellular communication and satellite positioning integration system and reducing the hardware complexity.

[0109] Among them, since the cellular communication module 10 is in a non-operating state, that is, when the cellular communication module 10 is powered off or in a sleep state, it cannot continue to supply power to the first switching unit 33. Therefore, before entering the non-operating state, the cellular communication module 10 controls the first switching unit 33 to select the satellite positioning matching circuit 32 to be enabled, so that the matching and tuning unit 30 can be stably in the second matching state.

[0110] In some other embodiments, as Figure 6 and Figure 7 shown, the satellite positioning module 40 and the cellular communication module 10 are jointly used to control the power supply module 60 to supply power or not supply power to the first switching unit 33 in the matching and tuning unit 30, and are jointly used to control the first switching unit 33 in the matching and tuning unit 30 to select the cellular matching circuit 31 or the satellite positioning matching circuit 32 to be enabled, so that the matching and tuning unit 30 is in the first matching state or the second matching state.

[0111] Through the joint 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-operating state or abnormal, the other module can be used to control the power supply module 60 and the first switching unit 33 to ensure that the first switching unit 33 works continuously and stably, and to ensure that the matching state of the matching and tuning unit 30 meets the communication requirements. Therefore, the matching and tuning unit 30 can be controlled to be in the second matching state at the moment when, before, or after the cellular communication module 10 enters the non-operating state.

[0112] When the cellular communication module 10 is in a normal operating state and / or the satellite positioning module 40 is in a normal operating state, the satellite positioning module 40 and the cellular communication module 10 control the power supply module 60 to supply power to the first switching unit 33. That is, as long as one of the cellular communication module 10 and the satellite positioning module 40 is in a normal operating state, the power supply module 60 can supply power to the first switching unit 33. Thus, when one of the cellular communication module 10 and the satellite positioning module 40 is in a non-operating state, the other can control the power supply module 60 to supply power to the first switching unit 33, thereby avoiding the problem that the matching tuning unit 30 may not be in the required matching state due to one of them being in a non-operating state.

[0113] When the cellular matching circuit 31 and the satellite positioning matching circuit 32 are connected between the first switching unit 33 and the matching tuning point 21 or the ground, if only the cellular communication module 10 supplies power to the first switching unit 33, when the cellular communication module 10 is in a non-operating state, the power supply module 60 does not supply power to the first switching unit 33, which may cause the state of the first switching unit 33 to be unstable. For example, it may switch to conduct other paths. In the embodiment of the present application, when any one of the cellular communication module 10 and the satellite positioning module 40 is in a normal operating state, the power supply module 60 can supply power to the first switching unit 33, thereby ensuring that the first switching unit 33 can still operate normally when one of the modules enters a non-operating state, and enabling the matching tuning unit 30 to be in a stable required matching state.

[0114] When the cellular communication module 10 is in a non-operating state, such as powered off or in a sleep state, and the satellite positioning module 40 is in a normal operating state, the power supply module 60 supplies power to the first switching unit 33. When the satellite positioning module 40 is in a non-operating state and the cellular communication module 10 is in a normal operating state, the power supply module 60 supplies power to the first switching unit 33. The non-operating state of the satellite positioning module 40 can be powered off or in a sleep state of the satellite positioning module 40. When both the cellular communication module 10 and the satellite positioning module 40 are in a normal operating state, the power supply module 60 supplies power to the first switching unit 33.

[0115] 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-operating state.

[0116] When the cellular communication module 10 is in a non-operating state and the satellite positioning module 40 is in a non-operating state, the power supply module 60 does not supply power to the first switching unit 33.

[0117] Among them, as Figure 6 and Figure 7 shown, the satellite positioning module 40 and the cellular communication module 10 are jointly used to control the power module 60 to supply power or not to the first switch unit 33 in the matching tuning unit 30, and are jointly used 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: the first modem 11 and the second modem 41 are jointly used to control the power module 60 to supply power or not to the first switch unit 33 in the matching tuning unit 30, and are jointly used 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.

[0118] In some embodiments, as Figure 6 and Figure 7 shown, the electronic device 100 further includes a first logic circuit 90, the first logic circuit 90 is 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 used to output a first switch control signal and a second switch control signal respectively, and the first logic circuit 90 is used to convert the first switch control signal and the second switch control signal into a switch logic for controlling the first switch unit 33, so as 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.

[0119] Through the first logic circuit 90, the cellular communication and satellite positioning functions can be intelligently managed, that is, the matching state of the matching tuning unit 30 is automatically switched according to the working state of the cellular communication module 10.

[0120] Among them, the first logic circuit 90 is used 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, so as to control the first switch unit 33 to select the cellular matching circuit 31 or the satellite positioning matching circuit 32 to be enabled.

[0121] 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 bands supported by the antenna 20 can be as shown in Table 1.

[0122] Table 1

[0123] 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.

[0124] For example, as Figure 6 and Figure 7 shown, the multiple sub-switch control signals of the first switch control signal output by the cellular communication module 10 are respectively an enable signal EN, a first line control signal IO1, and a second line control signal IO2. The satellite positioning module 40 outputs a second switch control signal IO3. The first logic circuit 90 generates a third switch control signal GPIO1 and a fourth switch control signal GPIO2. When the cellular communication module 10 is in a normal operating state and performs B5 band communication, the enable signal EN is 1, the first line control signal IO1 is B5, and the second line control signal IO2 is B5. When the cellular communication module 10 is in a normal operating state and performs B8 band communication, the enable signal EN is 1, the first line control signal IO1 is B8, and the second line control signal IO2 is B8. Wherein, the value of B5 is one of 0 or 1, and the value of B8 is the other of 0 or 1. When the cellular communication module 10 is in a non-operating state, the enable signal EN is 0.

[0125] When the satellite positioning module 40 is in a normal operating state, the second switch control signal IO3 is 1; when the satellite positioning module 40 is in a non-operating state, the second switch control signal IO3 is 0.

[0126] Exemplarily, the corresponding relationship between the first switch control signal and the second switch control signal IO3 and the third switch control signal GPIO1 and the fourth switch control signal GPIO2 can be as shown in Table 2. The corresponding relationship between the third switch control signal GPIO1 and the fourth switch control signal GPIO2 and the matching state of the matching tuning unit 30 and the frequency bands supported by the antenna 20 can be as shown in Table 3.

[0127] Table 2

[0128] Among them, X can be 0 or 1. Since when the enable signal EN is 0, it represents that the cellular communication module 10 is in a non-operating state, that is, the cellular communication module 10 does not work. Then, regardless of whether the first line control signal IO1 and the second line control signal IO2 are 0 or 1, the third switch control signal GPIO1 and the fourth switch control signal GPIO2 are both 1, so that the matching tuning unit 30 is in the second matching state, and the antenna 20 supports the satellite positioning frequency band.

[0129] Table 3

[0130] Among them, the sub-switch control signal of the first control signal can be configured according to the number of cellular communication frequency bands, such as 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.

[0131] In some embodiments, as Figure 6 and Figure 7 shown, the electronic device 100 further includes a second logic circuit 80. The second logic circuit 80 is 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 a first power control signal IO5 and a second power control signal IO4 respectively. The second logic circuit 80 is used to generate a third power control signal GPIO3 according to the first power control signal IO5 and the second power control signal IO4. 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.

[0132] The second logic circuit 80 serves as an intermediate control layer and can perform 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 a design helps to avoid power instability problems caused by misoperation or signal interference, and improves the stability and reliability of the control system.

[0133] Exemplarily, when the cellular communication module 10 is in a normal operating state, the first power control signal IO5 output by the cellular communication module 10 is 1. When the cellular communication module 10 is in a non-operating state, the first power control signal IO5 output by the cellular communication module 10 is 0. When the satellite positioning module 40 is in a normal operating state, the second power control signal IO4 output by the satellite positioning module 40 is 1. When the satellite positioning module 40 is in a non-operating state, the second power control signal IO4 output by the satellite positioning module 40 is 0. The corresponding relationships 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 switching unit 33 are shown in Table 4.

[0134] Table 4

[0135] In some embodiments, when the cellular communication module 10 is in a normal operating state, the matching tuning unit 30 is in the first matching state; when the cellular communication module 10 is in a non-operating state, the matching tuning unit 30 is in the second matching state.

[0136] Among them, when the cellular communication module 10 is in a normal operating state and the satellite positioning module 40 is in a non-operating state, the matching tuning unit 30 is in the first matching state. When the cellular communication module 10 is in a normal operating state and the satellite positioning module 40 is in a normal operating state, the matching tuning unit 30 is in the first matching state. When the cellular communication module 10 is in a non-operating state and the satellite positioning module 40 is in a normal operating state, the matching tuning unit 30 is in the second matching state. When the cellular communication module 10 is in a non-operating state and the satellite positioning module 40 is in a non-operating state, the matching tuning unit 30 is in the second matching state.

[0137] In some embodiments, the power module 60 includes a power supply and a second switching unit. The second switching unit is connected between the power supply and the first switching unit 33 in the matching tuning unit 30. The second logic circuit 80 is connected between the cellular communication module 10, the satellite positioning module 40, and the second switching unit. The second logic circuit 80 is configured to convert the first power control signal IO5 and the second power control signal IO4 into a switching logic for controlling the second switching unit, so as to control the second switching unit to conduct or disconnect, so that the power supply supplies power or does not supply power to the first switching unit 33. In some other embodiments, the power module 60 may also be other circuit structures.

[0138] In some embodiments, as Figures 5 to 7 shown, the first switch unit 33 further includes a power supply port Vdd, the power supply port Vdd is electrically connected to the power supply module 60, and the power supply module 60 supplies electrical energy to the first switch unit 33 through the power supply port Vdd.

[0139] In some embodiments, the first switch unit 33 further includes a control port, the control port can be one or more, and the control port can be electrically connected to the cellular communication module 10 or the satellite positioning module 40, or electrically connected to the first logic circuit 90.

[0140] For example, as Figure 5 shown, the first switch unit 33 includes a first control port Vctrl_1 and a second control port Vctrl_2, the first control port Vctrl_1 and the second control port Vctrl_2 are electrically connected to the cellular communication module 10, and the switch control signal output by the cellular communication module 10 is transmitted to the first switch unit 33 through the first control port Vctrl_1 and the second control port Vctrl_2.

[0141] Again for example, as Figure 6 and Figure 7 shown, the first switch unit 33 includes a first control port Vctrl_1 and a second control port Vctrl_2, the first control port Vctrl_1 and the second control port Vctrl_2 are electrically connected to the first logic circuit 90, and the third switch control signal and the fourth switch control signal output by the first logic circuit 90 are respectively transmitted to the first switch unit 33 through the first control port Vctrl_1 and the second control port Vctrl_2.

[0142] In some embodiments, the non - working state of the cellular communication module 10 is the sleep state when the cellular communication module 10 is in the idle state (Idle), RRC (Radio Resource Control) RRC connection state or network search state. The foregoing non - working state of the cellular communication module 10 may include the sleep state when the cellular communication module 10 is in the idle state, RRC connection state or network search state.

[0143] When the cellular communication module 10 enters the sleep state, it does not need to perform cellular communication. At this time, by controlling the matching tuning unit 30 to be in the second matching state, the antenna 20 supports the satellite positioning frequency band, which can effectively utilize the antenna 20, improve the utilization rate of the antenna 20, and meet the positioning requirements.

[0144] Among them, when the cellular communication module 10 is in the idle state (Idle), RRC connected state, or network search state, it may include that the first modem 11 is in the idle state (Idle), RRC connected state, or network search state.

[0145] Among them, when the electronic device 100 is powered on, restarted, loses network connection, or enters a service restricted state, the first modem 11 may be in the network search state. When the electronic device 100 is on standby, the first modem 11 may be in the idle state. When the electronic device 100 establishes a connection with the network and is in a data transmission state, the first modem 11 may be in the RRC connected state.

[0146] Among them, when the first modem 11 is in the idle state, it has an iDRX (Idle Mode DRX) cycle. During the iDRX cycle, the first modem 11 will work for a short period of time (RF state), for example, listening for paging messages, and enter the sleep state for the rest of the time to save power consumption. For example, please refer to Figure 8 , which is a schematic diagram of the working time slots in the idle state in some embodiments of this application. As Figure 8 shown, the idle state takes T1 as an iDRX cycle, and the first modem 11 only works during the T2 time period, and the first modem 11 is in the sleep state during the T3 time period. In some embodiments, T1 can be 0.32s to 1.28s, and T2 can be 20ms to 30ms. In other embodiments, T1 and T2 can also be other values.

[0147] In some embodiments, only the first modem 11 controls the matching state of the matching tuning unit 30, and the first modem 11 can control the matching tuning unit 30 to be in the second matching state before the start moment of the T3 time period in each iDRX cycle. In other embodiments, the first modem 11 and the second modem 41 jointly control the matching state of the matching tuning unit 30, and the first modem 11 and the second modem 41 can control the matching tuning unit 30 to be in the second matching state at or before or after the start moment of the T3 time period in each cycle.

[0148] When the first modem 11 is in the RRC connected state, it has a CDRX (Connected Mode DRX) cycle. During the CDRX cycle, the first modem 11 works for a period of time and enters the sleep state for the rest of the time to save power consumption. For example, if the cellular communication module 10 does not perform data transmission, the first modem 11 will enter the sleep state. For example, please refer toFigure 9 , which is a schematic diagram of the working time slots in the RRC connected state in some embodiments of the present application. As Figure 9 shown, the RRC connected state takes T4 as a period, and the first modem 11 works during the T5 time period, and the first modem 11 is in a sleep state during the T6 time period.

[0149] In some embodiments, only the first modem 11 controls the matching state of the matching tuning unit 30, and the first modem 11 can control the matching tuning unit 30 to be in the second matching state before the start moment of the T6 time period in each cycle. In other embodiments, the first modem 11 and the second modem 41 jointly control the matching state of the matching tuning unit 30, and the first modem 11 and the second modem 41 can control the matching tuning unit 30 to be in the second matching state at or before or after the start moment of the T6 time period in each cycle.

[0150] When the first modem 11 is in the network search state, the first modem 11 will perform network search to establish a network connection. During the network search process, in order to save power consumption, the first modem 11 will be in a sleep state periodically, that is, perform network search periodically. For example, please refer to Figure 10 , which is a schematic diagram of the working time slots in the network search state in some embodiments of the present application. As Figure 10 shown, the RRC connected state takes T7 as a network search period, the first modem 11 works during the T8 time period, and the first modem 11 is in a sleep state during the T9 time period.

[0151] In some embodiments, only the first modem 11 controls the matching state of the matching tuning unit 30, and the first modem 11 can control the matching tuning unit 30 to be in the second matching state before the start moment of the T9 time period in each cycle. In other embodiments, the first modem 11 and the second modem 41 jointly control the matching state of the matching tuning unit 30, and the first modem 11 and the second modem 41 can control the matching tuning unit 30 to be in the second matching state at or before or after the start moment of the T9 time period in each cycle.

[0152] Among them, the normal operating state of the aforementioned cellular communication module 10 may include the operating states of the cellular communication module 10 in the idle state, RRC connected state, and network search state, that is, it includes the operating state during the T2 time period within each iDRX cycle in the idle state, the T5 time period within each CDRX cycle in the RRC connected state, and the T8 time period within each network search cycle in the network search state.

[0153] In some embodiments, such as Figure 1 and Figure 2 shown, the electronic device 100 further includes a controller 95. The controller 95 is configured to send a notification signal to the cellular communication module 10 and / or the satellite positioning module 40 when the electronic device 100 is in a preset state, so as to notify the cellular communication module 10 and / or the satellite positioning module 40 to control the matching tuning unit to be in the second matching state, that is, to control the first switch unit 33 to select the satellite positioning matching circuit 32 to be enabled.

[0154] In some embodiments, the controller 95 is further configured to control the cellular communication module 10 to enter the non-operating state. For example, when the electronic device 100 is in a preset state, the controller 95 sends a power-down command or a sleep command to the first modem 11 of the cellular communication module 10, and the first modem 11 powers down when receiving the power-down command or enters the sleep state when receiving the sleep command.

[0155] Thus, the controller 95 can manage and coordinate the control of the first switch unit 33 by the cellular communication module 10 and the satellite positioning module 40 according to the state of the electronic device 100, and control the operating state of the cellular communication module 10 according to the state of the electronic device 100.

[0156] In some embodiments, the preset state includes at least one of the following: the electronic device 100 enters the flight mode; the electronic device 100 establishes a communication connection with a terminal, and the mobile communication unit of the terminal is operating normally; the electronic device 100 has not activated the identification card.

[0157] Among them, the electronic device 100 may include a wearable device, the terminal may include a mobile phone or other devices with cellular communication functions, and the mobile communication unit may be a cellular communication module located in the terminal. The identification card may be, for example, an eSIM card.

[0158] Among them, when the electronic device 100 is in the flight mode, the electronic device 100 does not need to perform cellular communication. At this time, the cellular communication module 10 will be in a non-operating state. By controlling the matching tuning unit 30 to be in the second matching state, the antenna 20 can support the satellite positioning frequency band. Thus, in the flight mode, the electronic device 100 can effectively utilize the antenna 20 for satellite positioning, and can ensure that the antenna performance of satellite positioning is fully exerted, thereby improving the accuracy of the satellite positioning trajectory.

[0159] Among them, when the electronic device 100 is communicatively connected to the terminal, it can be considered that cellular communication is not required at this time. At this time, the cellular communication module 10 will be in a non-operating state. By controlling the matching tuning unit 30 to be in the second matching state, the antenna 20 can support the satellite positioning frequency band. Thus, when the electronic device 100 is communicatively connected to other devices, the electronic device 100 can effectively utilize the antenna 20 for satellite positioning, and can ensure that the antenna performance of satellite positioning is fully exerted, thereby improving the accuracy of the satellite positioning trajectory. The communicative connection between the electronic device 100 and the terminal may include the electronic device 100 being Bluetooth-connected, Wifi-connected, or wired-connected to the terminal.

[0160] Among them, if the identity card is not inserted into the electronic device 100 or the identity card is not set, it means that the electronic device 100 does not have the condition to access cellular communication, that is, the electronic device 100 cannot perform cellular communication. At this time, the cellular communication module 10 will be in a non-operating state. By controlling the matching tuning unit 30 to be in the second matching state, the antenna 20 can support the satellite positioning frequency band. Thus, in the case where the identity card is not activated, the electronic device 100 can effectively utilize the antenna 20 for satellite positioning, and can ensure that the antenna performance of satellite positioning is fully exerted, thereby improving the accuracy of the satellite positioning trajectory.

[0161] It can be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may include more or fewer components than those illustrated, or combine certain components, or split certain components, or have different component arrangements. The illustrated components can be implemented in hardware, software, or a combination of software and hardware.

[0162] The embodiments of the present application further provide a communication control method, and the communication control method is applied to the electronic device 100 described in any of the foregoing embodiments. The communication control method includes the following steps: controlling the matching tuning unit 30 to be in the second matching state after the cellular communication module 10 enters the non-operating state, so that the antenna 20 supports the satellite positioning frequency band.

[0163] Among them, in some embodiments, the matching state of the matching tuning unit 30 is controlled by the cellular communication module 10. Before entering the non-operating state, the cellular communication module 10 controls the matching tuning unit 30 to be in the second matching state. Among them, after the cellular communication module 10 enters the non-operating state, the matching tuning unit 30 remains in the second matching state. Exemplarily, as Figure 5 shown, the electronic device 100 controls the matching state of the matching tuning unit 30 through the cellular communication module 10. Before entering the non-operating state, the cellular communication module 10 controls the matching tuning unit 30 to be in the second matching state. Among them, the matching state of the matching tuning unit 30 can be controlled through the first modem 11.

[0164] In other embodiments, the matching state of the matching tuning unit 30 is jointly controlled by the cellular communication module 10 and the satellite positioning module 40. The cellular communication module 10 and the satellite positioning module 40 can control the matching tuning unit 30 to be in the second matching state before or after the cellular communication module 10 enters the non-operating state. Exemplarily, as Figure 6 and Figure 7 shown, the electronic device 100 jointly controls the matching state of the matching tuning unit 30 through the cellular communication module 10 and the satellite positioning module 40. The cellular communication module 10 and the satellite positioning module 40 can control the matching tuning unit 30 to be in the second matching state before or after the cellular communication module 10 enters the non-operating state. Among them, the matching state of the matching tuning unit 30 can be jointly controlled through the first modem 11 and the second modem 41.

[0165] In some embodiments, the communication control method further includes the step of: controlling the matching tuning unit 30 to be in the first matching state after the cellular communication module 10 enters the normal operating state, so that the antenna supports the satellite positioning frequency band. Thus, not only can cellular communication be performed when the cellular communication module 10 is operating normally, but also the antenna performance of cellular communication can be fully utilized, thereby ensuring the quality of cellular communication.

[0166] In some embodiments, the communication control method further includes the step of: when the electronic device 100 is in a preset state, the controller 95 sends a notification signal to the cellular communication module 10 and / or the satellite positioning module 40 to notify the cellular communication module 10 and / or the satellite positioning module 40 to control the first switch unit 33 to select the satellite positioning matching circuit 32 to be enabled, and control the cellular communication module 10 to enter the non-operating state.

[0167] In some embodiments, it is possible to sequentially determine whether the electronic device 100 activates the identification card, whether the electronic device 100 is communicatively connected to the terminal, whether the electronic device 100 is in flight mode, whether the electronic device 100 is in a sleep state, and control the matching state of the matching tuning unit 30 according to the determination results.

[0168] Exemplarily, please refer to Figure 11 , which is a flowchart of the communication control method in some embodiments of the present application. In some embodiments, as Figure 11 shown, the communication control method includes the following steps: S1: Determine whether the electronic device 100 activates the identification card. If so, execute step S2; if not, execute step S5.

[0169] S2: Determine whether the electronic device 100 is communicatively connected to the terminal. If not, execute step S3; if so, execute step S5.

[0170] S3: Determine whether the electronic device 100 is in flight mode. If not, execute S4; if so, execute S5.

[0171] S4: Determine whether the electronic device 100 is in a sleep state. If not, execute S6; if so, execute S5.

[0172] S5: Control the matching tuning unit 30 to be in the second matching state after the cellular communication module 10 enters the non-working state, so that the antenna 20 supports the satellite positioning frequency band.

[0173] S6: Control the matching tuning unit 30 to be in the first matching state after the cellular communication module 10 enters the normal working state, so that the antenna 20 supports the cellular communication frequency band.

[0174] Among them, the sleep state in step S5 may include the sleep states in the aforementioned idle state, RRC connection state, and network search state.
