Problems solved by technology
The time overhead in the data service process of the mobile phone includes the time-consuming basic data processing operations of the mobile phone and the time-consuming data interaction with network equipment. When the mobile phone is in a weak signal field and / or the received data signal is greatly interfered , the bit error rate of the data signal is high, which will lead to transmission delay or multiple data retransmissions during the data interaction process, affecting the real-time performance of data services

Embodiments of the invention disclose a transmission control method and device. The method comprises the steps of when a mobile terminal detects that the mobile terminal enters a preset position, acquiring a network state of the mobile terminal, wherein the preset position is, in a historical position record of the mobile terminal, a position with an occurrence frequency higher than a preset frequency threshold among positions in which the mobile terminal is when the network state of the mobile terminal is a first network state; when it is detected that the network state is in the first network state, determining that a signal transmission mode of the mobile terminal is a diversity transmission mode, wherein the first network state is used for indicating that the mobile terminal is in a weak signal field; notifying a network device to transmit a data signal with the mobile terminal in the diversity transmission mode; and controlling a RF system of the mobile terminal to transmit a datasignal with the network device in the diversity transmission mode. The transmission control method can help shorten transmission delay of data exchange between the mobile terminal and the network device in the weak signal field and improve data transmission reliability.
Description
technical field [0001] The present application relates to the technical field of mobile terminals, in particular to a transmission control method and device. Background technique [0002] With the rapid development of technologies related to mobile terminals such as smart phones, more and more applications are installed in users' mobile phones, such as reading applications, payment applications, game applications, music applications, etc. People's basic necessities of life have been closely related to Mobile phones are inseparable. The time overhead in the data service process of mobile phones includes the time-consuming basic data processing operations of the mobile phone and the time-consuming data interaction with network devices. When the mobile phone is in a weak signal field and / or the received data signal is greatly interfered , the bit error rate of the data signal is high, which will lead to transmission delay or multiple data retransmissions during the data intera...
