Problems solved by technology

However, once the transmission channel of the Bluetooth car charger coincides or is close to the channel of the local radio station, it will cause co-channel interference, which will affect the reception of the car radio device, resulting in noise and mixing
If you try one by one to avoid channel overlap, it will be cumbersome and affect driving safety

Embodiment Construction

[0014] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] The application scenario of the embodiment provided by the present invention is: after the radio broadcast transmission channel selection device (such as an intelligent mobile terminal) is paired and connected with a vehicle-mounted Bluetooth device (such as a Bluetooth vehicle charger), the mobile terminal chooses to avoid the channel of the local radio station and control the vehicle-mounted Bluetooth device to send radio broadcasts on this channel, and notify the user of the transmission channel used by the vehicle-mounted Bluetooth device, and...

Abstract

The invention discloses a selection method and device for a radio broadcast transmitting channel. The method comprises the steps of determining a region in which a user is located currently and determining a broadcast full channel list of radio broadcast of the region according to a mapping relationship between the broadcast full channel list and the region, wherein the broadcast full channel listcomprises all channels of the local radio broadcast; determining a forbidden channel interval according to the broadcast full channel list; selecting the channel out of the forbidden channel intervalas the transmitting channel; and controlling a vehicular Bluetooth device to transmit a radio signal through utilization of the transmitting channel after paired connection is established with the vehicular Bluetooth device. According to the scheme, the local radio broadcast channels can be queried and when the transmitting channel of a Bluetooth vehicular charger is set, the local radio broadcast transmitting channels are automatically avoided, so the radio broadcast transmitting channel is smartly selected.

Description

【Technical field】 [0001] The invention relates to the technical field of communication, in particular to a method and device for selecting a radio broadcast transmission channel. 【Background technique】 [0002] At present, some Bluetooth car chargers can realize the effective connection between the user's mobile phone and the car radio device, such as: connecting the user's mobile phone and the car radio device through the Bluetooth car charger, and yes, the car radio device can play audio files in the user's mobile phone, or call voice etc. In this way, the user's demands for wireless calls and wireless music playback can be solved. Therefore, the use of such products is becoming more and more extensive. However, once the transmission channel of the Bluetooth car charger coincides or is close to the channel of the local radio station, it will cause co-channel interference, which will affect the reception of the car radio device, resulting in noise and mixing. If you try ...
