Specifically, when the mobile terminal device moves from the current communication area to the next communication area, the signal frequency band to which the communication signal received by the antenna of the mobile terminal device belongs may also change, for example, if the terminal antenna of the terminal device is in the communication area at the current time, and the received communication signal frequency band is 1710-2170M, the signal frequency band-1710-2170M to which the communication signal at the current time belongs is detected, which is different from the signal frequency band-700-960M to which the received communication signal belongs in the communication area at the previous time of the current mobile terminal device, and the signal frequency band-1710-2170M to which the received communication signal belongs in the communication area at the current time of the terminal antenna of the mobile terminal device is acquired.

Detecting whether a communication area where the mobile terminal is currently located changes or not, and when detecting that the communication area changes, starting to detect whether a signal frequency band to which a communication signal received by a terminal antenna of the mobile terminal belongs changes or not.
Specifically, for example, the current communication signals belong to different signal frequency bands in different communication areas, and when it is detected that the communication area where the terminal device is currently located is changed, the terminal antenna of the current mobile terminal is detected, and if the signal frequency band to which the received communication signal belongs is different from the signal frequency band to which the communication signal received by the terminal antenna belongs when the mobile terminal is located in the previous communication area, the terminal antenna starts to detect the terminal antenna of the current mobile terminal.
Further, in another embodiment, when it is detected that the communication area where the terminal device is currently located is not changed, the terminal antenna of the current mobile terminal is not detected, and the signal frequency band to which the received communication signal belongs is not the same as the signal frequency band to which the communication signal received by the terminal antenna belongs when the mobile terminal is located in the previous communication area, so that a trigger mechanism is set for the mobile terminal device to detect whether the communication signal received by the terminal antenna and the signal frequency band to which the communication signal belongs are changed, so as to ensure the overall operating efficiency of the mobile terminal device.

Specifically, for example, after acquiring the terminal antenna of the mobile terminal device and in the communication area where the current time is, the signal frequency band — 1710-2170M to which the received communication signal belongs is detected, whether the signal frequency band — 1710-2170M belongs to one of the signal frequency band categories in the preset antenna length list of the current mobile terminal device terminal antenna, as shown in fig. 7, or not is detected, and if it is detected that the signal frequency band — 1710-2170M belongs to one of the signal frequency band categories in the preset antenna length list, the current signal frequency band — 1710-2170M is matched in the preset antenna length list, and the antenna length of the current mobile terminal device terminal antenna corresponding to the antenna length category in the preset antenna length list is obtained.
It should be noted that: the preset antenna length list is: the preset antenna length lists of all the signal frequency bands and the corresponding terminal antennas, such as the preset antenna length list shown in the mobile terminal interface shown in fig. 7, are generated by correspondingly setting the lengths of all the sections of the terminal antennas of the mobile terminal equipment based on the coverage range of the antenna frequency bands at present, international and domestic.
Specifically, for example, in the scenario diagram for generating the preset antenna length list shown in fig. 6A, first, a terminal antenna feed point of the current mobile terminal device based on a metal frame, a length 2 from the end of the metal frame of the current mobile terminal device, and a length 1 of the whole metal frame are determined, an upper limit of an initial signal frequency band of the terminal antenna in a standard signal frequency band range is set, that is, an original frequency band of a low-frequency signal frequency band 700-960M is set to 900-960M, an original frequency band of an intermediate-frequency signal frequency band 1710-2170M is set to 1985-2170M, and an original frequency band of a high-frequency signal frequency band 2300-2700M is set to 2650-2700M; then, determining the lower limit of the range of the standard signal frequency band needing debugging, namely the lowest frequency band of 700-960M of the low-frequency signal frequency band is 700M, the lowest frequency band of 1710-2170M of the intermediate-frequency signal frequency band is 1710M, and the lowest frequency band of 2300-2700M of the high-frequency signal frequency band is 2300M; and finally, the length of each segment of the terminal antenna based on the metal frame is as follows: the length of 1+ a, the length of 1+ b and the length of 1+ c are respectively matched with the low-frequency signal frequency band, the intermediate-frequency signal frequency band and the high-frequency signal frequency band of the communication signal, and therefore a preset antenna length list of the terminal antenna based on the metal frame of the current mobile terminal device is generated.
Further, step S20 includes:
step S21, detecting whether the signal frequency band belongs to the preset antenna length list of the current terminal antenna.
After the signal frequency band of the terminal antenna of the mobile terminal is obtained and the signal frequency band to which the communication signal belongs is changed, whether the obtained signal frequency band belongs to the signal frequency band category in the preset antenna length list of the current terminal antenna is detected.
Specifically, for example, after acquiring a signal frequency band-1710-2170M to which a received communication signal belongs in a communication area in which a terminal antenna of the current mobile terminal device is located at the current time, it is detected whether the signal frequency band-1710-2170M belongs to a preset antenna length list of a terminal antenna based on a metal frame of the current mobile terminal device, which is shown in the mobile terminal interface shown in fig. 7, that is, whether the signal frequency band is of one of signal frequency band classes in the preset antenna length list is detected.
And step S22, if the antenna length belongs to the preset antenna length list, matching the antenna length of the terminal antenna corresponding to the signal frequency band in the antenna length category of the preset antenna length list.
And if the acquired signal frequency band is detected to belong to the signal frequency band category in the preset antenna length list of the current terminal antenna, matching the antenna length of the current terminal antenna according to the acquired signal frequency band in the antenna length category of the preset antenna length list of the current terminal antenna.
Specifically, for example, when detecting that a signal frequency band 1710-2170M to which a communication signal received at the current time of the terminal antenna belongs is one of signal frequency band categories in a preset antenna length list of the current terminal antenna, it is determined that the signal frequency band 1710-2170M belongs to the current preset antenna length list, and then the antenna length of the terminal antenna corresponding to the signal frequency band 1710-2170M is matched in the antenna length category of the preset antenna length list.
And S30, controlling a circuit between the corresponding resistors connected with the switch according to the antenna length so as to adjust the antenna length of the terminal antenna.
It should be noted that: the metal frame and the resistors form a feed loop of the terminal antenna through the single-pole multi-throw switch, and the single-pole multi-throw switch is connected with circuits among the different resistors and correspondingly forms a plurality of different antenna lengths of the terminal antenna.
When the antenna length of the current terminal antenna is matched in the preset antenna length list according to the signal frequency band to which the communication signal currently received by the terminal antenna belongs, the number of the resistors accessed in the feed loop of the mobile terminal antenna is adjusted according to the antenna length so as to adjust the antenna length of the terminal of the current mobile terminal antenna, and the current terminal antenna can receive the communication signal of the currently changed signal frequency band conveniently.
Further, step S30 includes:
