Method and device for acquiring channel frequency point and mobile terminal

Abstract

The invention provides a method and device and a mobile terminal for acquiring channel frequency points. The method is applied to a mobile terminal, wherein a baseband chip and an application processor connected with each other are arranged in the mobile terminal; The method comprises the following steps: when the baseband chip receives the communication connection control signaling from the network side, the baseband chip extracts the current channel frequency point of the mobile terminal from the communication connection control signaling; The baseband chip reports the channel frequency point to the application processor. The processor is used to judge whether the channel frequency point of the mobile terminal is changed or not. If so, the application processor stores the channel frequency points reported by the baseband chip. In the invention, the baseband chip can extract the channel frequency point from the communication connection control signaling and report the channel frequency point to the application processor actively, which improves the convenience and real-time of the channel frequency point acquisition operation, is favorable for the subsequent mobile terminal to optimize the performance according to the channel frequency point, and can also meet the requirements of the operator.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, and in particular to a method, device and mobile terminal for obtaining channel frequency points. Background technique [0002] When the mobile terminal is turned on, or in other situations where it needs to re-access the mobile communication network, the mobile terminal usually searches for network cells and registers. After the registration is completed, the mobile terminal works on a specific channel frequency under a certain network standard. [0003] With the continuous development of mobile terminal software and hardware, mobile terminals often need to obtain the current channel frequency to optimize terminal performance or meet other needs; however, in the existing channel frequency acquisition method, it is necessary to query the mobile terminal baseband chip The channel frequency is extracted from the relevant information; sometimes it is even necessary to find the channe...
