Problems solved by technology

Generally, the frequency range of 2.4G WIFI is 2403-2481MHz. Since the frequency band of WIFI is relatively close to some frequency bands of LTE, it is difficult to achieve ideal control of interference between adjacent frequency bands through out-of-band suppression through the filter configured in the baseband of the terminal equipment. Therefore, if the user wants to use the LTE network for voice calls and at the same time use the WIFI network for activities such as surfing the Internet, the two signals will interfere with each other and affect the quality of communication

Abstract

The embodiment of the invention relates to the technical field of communication, and discloses an LTE frequency band selecting method and device. The method comprises the following steps: determining whether a terminal device needs to use a Wireless Fidelity WIFI function and a long term evolution LTE function at the same time; if so, acquiring an LTE frequency band set that is supported by the terminal device at present; and selecting a first frequency band away from the WIFI frequency band from the LTE frequency band set that is supported by the terminal device at present to transmit LTE data. Therefore, by implementation of the embodiment of the invention, adjacent frequency band interference in a use process of WIFI and LTE can be avoided, and thus the communication quality is guaranteed.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and device for selecting an LTE frequency band. Background technique [0002] With the development of communication technology, LTE (Long Term Evolution, Long Term Evolution) is more and more widely used, LTE technology can be classified as 4G network technology, and in the early stage of LTE technology application, voice calls still need to fall back to 2G Or 3G network, until the emergence of VoLTE (Voice over LTE, voice over LTE) technology, making use of LTE to make voice calls become a reality. In addition to using the LTE network in the terminal device, the terminal device often also has a WIFI function, and the user can also access the WIFI network to realize data transmission. Generally, the frequency range of 2.4G WIFI is 2403-2481MHz. Since the frequency band of WIFI is relatively close to some frequency bands of LTE, it is difficult to a...
