The impact of the user communication needs. The implementation process of the embodiment of the present invention will be described in detail below with reference to examples. Example 1 In this example, an implementation method for guaranteeing communication quality of a mobile terminal is provided. 4 is a schematic diagram of a processing flow of a method for guaranteeing communication quality according to the first embodiment of the present invention. As shown in FIG. 4, the process mainly includes the following processing: Step S402, acquiring the traveling speed of the current vehicle (ie, the moving speed of the mobile terminal) by using the GPS. For example, the GPS can be set in the mobile terminal, wherein the GPS has the function of acquiring the GPS traveling speed in real time, and the traveling speed of the current vehicle (for example, a train, a car, etc.) can be acquired by the GPS. In a specific implementation process, the traveling speed of the current vehicle may be acquired from the GPS in real time, or the current vehicle traveling speed may be acquired periodically, which may be implemented by a timer. Specifically, it may be that a fixed time is preset in the timer, and then the timer is started. When the time reaches a preset fixed time, the current vehicle traveling speed is acquired from the GPS, and the timer is restarted; After reaching the preset fixed time, the current vehicle travel speed is acquired from the GPS, and so on. Step S404, comparing the acquired travel speed value of the current vehicle with a preset standard speed value (ie, a speed threshold). If the traveling speed of the current vehicle is greater than a preset standard speed value, step S406 is performed; otherwise, step S408 is performed. Step S406, the mobile phone reduces the RSCP value and/or the SIR value of the mobile phone network signal indicator value. For example, mobile terminals can be based on the 3rd Generation Partnership (3rd Generation Partnership)

Project, abbreviated as 3GPP) protocol, adjusts its own radio frequency transmit power, and reports the network quality to the network. The base station then adjusts the transmit power of the mobile phone link according to the 3GPP protocol standard, so as to affect the signal attenuation and noise interference. Guarantee the quality of mobile communication business in high-speed mobile state. In step S406, the mobile phone network signal indicator value is not lowered, that is, the network signal is not adjusted. It can be seen that, in this embodiment, the current speed of the traveling train (ie, the carrier of the mobile terminal, whose speed also reflects the moving speed of the mobile terminal) is compared with the preset standard traveling speed, when the current speed of the train is less than the preset speed. When the standard driving speed is not adjusted, when the current speed of the train is greater than the preset standard driving speed, the transmitting power of the signal transmission is adjusted to overcome the effects of signal attenuation and noise interference. In this way, problems such as poor voice quality, dropped calls, and abnormal data services can be avoided, which satisfies the business requirement of using mobile phones for communication in high-speed mobile vehicles, and ensures the communication quality of mobile phones during high-speed mobile. Example 2 This example describes in detail how to secure the communication quality of the mobile terminal during the high-speed movement of the mobile terminal. 5 is a high-speed mobile secured mobile phone pass according to Example 2 of the present invention. As shown in FIG. 5, the method includes the following steps: Step S502: Determine whether the current mode of the mobile terminal is a high-speed mobile communication security mode. If yes, step S504 is performed; otherwise, the flow is ended. In the specific implementation process, the high-speed mobile communication security mode can be set to the default mode of the mobile terminal. Step S504, the travel speed of the current train, that is, the travel speed value of the current vehicle, is acquired by the GSP. Step S506, comparing the acquired driving speed value of the current vehicle with a preset standard speed value. If the traveling speed of the current vehicle is greater than the preset speed standard speed, step S508 is performed; otherwise, step S510 is performed. Step S508, the mobile phone reduces the RSCP value and/or the SIR value of the mobile phone network signal indicator value. In the specific implementation process, the mobile phone can adjust its own radio frequency transmission power according to the 3GPP ten-party discussion, and report the network quality to the network, and the base station can also adjust the transmission power of the mobile phone link according to the 3GPP protocol standard. In this way, the quality of mobile communication service in high-speed mobile state is guaranteed. Then return to step 4 to gather S504. In step S510, the mobile phone network signal indicator value is not lowered, that is, the mobile phone network signal is not adjusted, and the process returns to step S504. Through the embodiment, the communication signal of the high-speed mobile phone is improved, so that the mobile terminal can maintain the normal connection of the communication signal during the high-speed movement, and meets the requirement of the user to use the mobile phone service communication in the high-speed mobile process. Example 3 FIG. 6 is a structural block diagram of a mobile terminal according to Embodiment 3 of the present invention. As shown in FIG. 6, the mobile terminal includes: a current vehicle traveling speed acquiring unit 62, a speed comparing unit 64, and a high-speed moving state signal processing unit. 66, the following describes each part in detail. The current vehicle travel speed obtaining unit 62 is configured to obtain the current travel speed of the vehicle by using the GPS function (the unit may include the GPS module 622), and transmit the obtained current travel speed of the vehicle to the speed comparison. Unit 64. The speed comparison unit 64 is configured to compare the travel speed value of the current vehicle with a preset standard speed value, and if the mobile terminal appears to be faster than the preset speed standard value, immediately send a start command to the high speed movement state signal processing unit 66. The high-speed mobile state signal processing unit 66 is configured to receive the start command, and control the mobile phone to reduce the RSCP value and the SIR value of the mobile phone network signal indicator value. In the specific implementation process, the mobile phone can increase the self-view radio transmission power according to the 3GPP protocol, and report the network quality parameter to the network, and the network can also control the base station to increase the transmission power of the mobile phone link according to the 3GPP protocol standard. Preferably, the mobile terminal further includes: a mobile communication unit 68, configured to instruct the mobile phone to increase its own radio frequency transmission power, and to adjust the network quality parameter to the network; and instruct the base station to increase the transmission power of the mobile phone link. Specifically, the high-speed mobile state signal processing unit 66 sends the reduced mobile phone network signal value to the mobile communication unit 68 after lowering the mobile phone network signal indicator. The mobile communication unit 68 instructs the mobile phone to increase the self-view radio frequency transmission power according to the received reduced mobile phone network signal value, and instructs the base station to increase the transmission power of the mobile phone link. It can be seen that, in the embodiment of the present invention, the standard traveling speed value is preset, the traveling speed of the vehicle currently located by the mobile terminal is acquired by the GPS function, and then the obtained traveling speed and the preset standard speed are compared, if the obtained traveling speed is obtained. When the value exceeds the preset standard driving speed value, the high-speed moving state signal processing unit 66 is immediately activated to lower the network signal index value, thereby increasing the link transmission power of the base station and the mobile terminal according to the 3GPP protocol standard. In this way, by increasing the signal link transmit power, the effects of signal attenuation and noise interference can be overcome to meet the user's demand for mobile phone service communication. In summary, according to the foregoing embodiment, when the current mobile speed of the mobile terminal is greater than the speed threshold, the network signal indicator value is decreased, thereby increasing the corresponding transmit power of the mobile terminal, and the mobile terminal is in the related art. The problem of poor communication quality during the mobile process overcomes the effects of signal attenuation and noise interference and improves the user experience.
