Abstract

The invention provides a method and a device for inhibiting interference of GSMon Bluetooth and a mobile terminal. The method comprises the following steps: when a GSM service and a Bluetooth functionare started at the same time, obtaining a frequency band currently used by the GSM service, an intermediate frequency of the GSM service and a sending / receiving channel frequency; calculating a Bluetooth channel under the GSM service according to the frequency band currently used by the GSM service, the intermediate frequency of the GSM and the frequency of the sending / receiving channel; and performing intermediate frequency hopping operation on the Bluetooth channel. According to the invention, the interference of the GSM to the Bluetooth can be effectively inhibited, the Bluetooth receivingsensitivity is improved, and the Bluetooth receiving error rate is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and mobile terminal for suppressing GSM interference to Bluetooth. Background technique [0002] When a user uses a GSM (Global System for Mobile communication) mobile terminal to make a call or find a network in a cell, the Bluetooth receiving sensitivity of the mobile terminal will become abnormal. Among them, the bit error rate of Bluetooth reception will increase to 7% to 9.5%, and the sensitivity of Bluetooth reception will deteriorate by about 30dB. This deterioration in sensitivity is unacceptable for users using the Bluetooth function. Moreover, other bluetooth receiving devices will not normally demodulate the interfered bluetooth signal. Contents of the invention [0003] The method, device and mobile terminal for suppressing the interference of GSM to Bluetooth provided by the invention can effectively suppress the interference of GSM to Blu...
