[0022] Such as figure 1 As shown, the embodiment of the present invention provides a switching control method for a terminal antenna. The switching control method can be applied to a terminal, and the terminal can specifically be a smart phone, a tablet computer / PAD, a personal computer, or other equipment. The switching control method includes :

[0023] Step 101: When the terminal antenna communicates with the wireless access point AP in MIMO mode, obtain the received signal strength value of the AP, the link quality value between the terminal and the AP, and the access bandwidth value of the AP.

[0024] Here, when the terminal antenna works in MIMO mode, it uses multiple transmit antennas and multiple receive antennas to communicate with the AP, and when the terminal antenna works in SISO mode, it uses one transmit antenna and one receive antenna to communicate with the AP.

[0025] When it is detected that the terminal antenna communicates with the AP in MIMO mode, it de...

Abstract

The invention provides a terminal antenna switching control method and a terminal, and solves the problem of increased power consumption of the existing terminal antenna due to a fact that a WI-FI (Wireless Fidelity) MIMO is used for transmitting data. The switching control method provided by the invention comprises the following steps: when the terminal antenna carries out communication with a wireless AP via an MIMO manner, obtaining a received signal intensity value of the AP, a link quality value between a terminal and the AP, and an access bandwidth value of the AP; and when the received signal intensity valve of the AP is greater than a first preset threshold value, the link quality value between the terminal and the AP is greater than a second preset threshold value, and the access bandwidth value of the AP is smaller than a third preset threshold value, controlling the terminal antenna to switch to an SISO manner to carry out communication with the AP. According to the terminal antenna switching control method and the terminal disclosed by the invention, on the premise of not affecting the internet-surfing experience of a user, the electricity loss of the terminal is saved; and thus, the service life of the terminal is increased.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to a terminal antenna switching control method and a terminal. Background technique [0002] With the popularity of smartphones, the use of Wi-Fi is becoming more and more widespread. As people have higher and higher requirements for the timeliness of accessing the network, multiple-input multiple-output MIMO technology and corresponding chips are more and more applied to mobile phone products, and Wi-Fi data transmission technology is gradually changing from single-antenna (single-input single-output SISO ) to multi-antenna (multiple-input multiple-output MIMO) transition. [0003] During the actual Internet access process of mobile phones, the network is mainly limited by the access bandwidth of the third-tier network and the transmission speed of the second-tier Wi-Fi. Compared with SISO, Wi-Fi MIMO only improves the transmission rate of Layer 2 Wi-Fi...
