Abstract

The invention discloses a frequency band switching control method and system based on a mobile terminal. The method comprises the steps of setting a timer for recording the switching times between a high frequency antenna and a low frequency antenna of the mobile terminal; detecting increase values of the counter under a time interval of a second in a latest first time period, and if the increase values of the counter exceed a threshold value, forbidding switching the antennas; and detecting the increase values of the counter under the time interval of the second in a latest first time period, if the increase values of the counter do not exceed the threshold value, allowing to switch the antennas. According to the method and the system, the problem that the radio wave receiving and transmitting efficiency is low due to the following frequent switching of the antennas when the mobile terminal is switched between a high frequency and a low frequency frequently is solved.

Description

Technical field [0001] The invention relates to the field of mobile terminals, in particular to a frequency band switching control method and system based on mobile terminals. Background technique [0002] Communication is one of the most basic functions of a mobile terminal. The mobile terminal communicates with the base station through radio waves anytime and anywhere; the mobile terminal transmits and receives wireless batteries through the antenna; currently mobile terminals often support multiple radio frequency bands, in these frequency bands Some frequency bands (such as LTE BAND39) are relatively high, and some frequency bands (such as GSM850) are relatively low. In order to achieve better performance, one antenna is used for the high frequency band in the mobile terminal, and another antenna is used for the low frequency band. [0003] In the actual use of mobile terminals, occasionally, the mobile terminal is at the junction of high and low frequencies. For example, the m...
