Wherein the plurality of metal segments 31 may form a plurality of antennas of the electronic device 100 for transmitting and/or receiving communication signals. Different metal segments 31 may form different antennas, or multiple metal segments 31 may form one antenna, or the same metal segment 31 may be multiplexed into multiple antennas. One antenna may cover one or more communication bands. Herein, "and/or" is only one kind of association relationship describing the association object, and means that there may be three kinds of relationships, for example, a and/or B, and may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more than two unless otherwise specified.
Understandably, the length, material, shape, and peripheral structure of the metal segment 31 determine the operating frequency band of the antenna, and the parameters of the metal segment 31 can be designed according to the requirement, which is not limited in the present application.

The Beidou short message function refers to a communication technology for directly carrying out bidirectional information transmission between the Beidou ground terminal and the Beidou satellite and between the Beidou ground monitoring master station through satellite signals. Therefore, the Beidou short message function is realized without the support of other communication systems, so that the Beidou ground terminal can realize the communication function in areas (such as unmanned areas, desert areas, polar areas and the like) which cannot be covered by communication signals or under the condition that a communication base station is damaged (such as earthquakes, floods, typhoons and the like). For example, the implementation of the beidou short message function requires the support of two antennas, and the two antennas are respectively used for transmitting and receiving beidou short message signals.
WiFi and bluetooth are wireless networking technologies that enable wireless communication within a certain range.
Cellular mobile communication is a wireless communication technology, and a mesh structure is adopted to realize large-area wireless communication. For example, cellular mobile communications may employ a variety of network types, such as: global system for mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Long Term Evolution (LTE), and the like. Cellular mobile communications may also employ multiple communications bands, such as: n41, N78, N79, and the like. In an embodiment of the present application, the electronic device 100 may employ N41 as an operating frequency band for cellular mobile communications.
Understandably, the electronic device 100 may also support other communication functions, such as: near Field Communication (NFC), Frequency Modulation (FM), Infrared (IR), and/or the like, which are not limited in this application.

The existing electronic device 100a, such as a mobile phone/PAD terminal, generally supports communication functions such as GPS L1, 2.4G WiFi, and cellular Band41, and the electronic device 100a includes modules, transceiving channels, and antennas corresponding to different communication functions.

If the big dipper short message mode needs to be added, a radio frequency circuit transceiving channel and an independent antenna of big dipper need to be added separately, that is, an antenna needs to be added separately in the existing mobile phone/PAD terminal. The space of the existing mobile phone/PAD terminal is limited, and the increase of the number of antennas can influence the layout of the mobile phone and the performance of other antennas.
Referring to fig. 1 and4 together, fig. 4 is a schematic view of a part of the structure of the electronic device 100 shown in fig. 1.

The second module 72 is connected to the second antenna 312 via the second path 75, and can transmit and receive signals via the second antenna 312. The beidou baseband module 73 is connected with the first antenna 311 through the beidou uplink path 76 and is connected with the second antenna 312 through the beidou downlink path 77. The big dipper baseband module 73 transmits the big dipper short message signal through the first antenna 311, and receives the big dipper short message signal through the second antenna 312, thereby completing the big dipper short message communication.

For example, the working frequency band of the first antenna 311 may cover the working frequency band of the first module 71 and the working frequency band of the uplink mode of the beidou short message signal, so that the first antenna 311 may simultaneously implement signal transmission of the first module 71 and sending of the beidou short message signal. The working frequency band of the second antenna 312 may cover the working frequency band of the second module 72 and the working frequency band of the downlink mode of the beidou short message signal, so as to simultaneously implement the receiving of the beidou short message signal and the signal transmission of the second module 72.
For example, the first module 71, the second module 72, or the beidou baseband module 73 may include, but are not limited to, a radio frequency chip, a baseband chip, and related peripheral circuits. The chip structures and circuit structures of the first module 71, the second module 72 and the beidou baseband module 73 can be independent components, and can also multiplex the same components.
For example, the communication module 7 may further include a first switch 78 and a second switch 79, that is, the electronic device 100 may further include the first switch 78 and the second switch 79, so as to implement the time division operation of the beidou baseband module 73 and the first module 71 and the second module 72, avoid mutual interference between different functional signals, prevent problems such as data loss, and improve the data transmission performance.
In one aspect, the first switch 78 connects the first antenna 311 with the first path 74 or the beidou uplink path 76 to implement the time division operation of the first module 71 and the beidou baseband module 73.

In addition, in a daily application scenario of the user, the electronic device 100 may be located in an environment with weak communication signals, such as a garage, a basement, or a suburban area, and at this time, the user does not need to start the beidou short message function. The user determines whether to start the Beidou short message function, so that unnecessary energy loss caused by starting the Beidou short message function under the condition that the communication signal is weak but the Beidou short message function is not needed is effectively avoided, energy distribution is optimized, and energy use efficiency is improved.
In other embodiments, the user may also turn on or off the beidou short message function in any case.

In other embodiments, the beidou short message function key 12 may also be an entity key arranged on the appearance surface of the electronic device 100, and the user can turn on or turn off the beidou short message function through interaction with the beidou short message function key 12, so that the experience of the user in using the beidou short message function is improved.
In the present application, the electronic device 100 may have functions that require a communication system support, such as GPS, WiFi, cellular mobile communication, bluetooth, and the like, so that the electronic device 100 can implement the communication function in an environment supported by the communication system. In addition, the electronic device 100 also integrates a beidou short message function, so that the electronic device 100 can also realize a communication function without the support of a communication base station and the like, and the electronic device 100 has various application environments and strong adaptability.
In addition, the transmission of the big dipper short message signal and the signal transmission of the first module 71 are realized through the first antenna 311, the reception of the big dipper short message signal and the signal transmission of the second module 72 are realized through the second antenna 312, so that the electronic device 100 does not increase the number of antennas when increasing the big dipper short message function, and the antenna architecture is not affected, thereby avoiding the problems of index reduction and cost rise caused by the increase of the antennas, and being beneficial to the application of the big dipper short message function in the electronic device 100.
