Embodiment Construction

[0012] Attached below figure 1 The preferred embodiments of the present invention are given to describe the technical solution of the present invention in detail.

[0013] The radio automatic channel selection module in the present invention can be set in mobile terminals such as mobile phones or PCs. It includes a database module, and a retrieval module for searching in the database module. The database module in this embodiment includes a station logo list, a list of cities where the station can be listened to, and FM channel information of the station corresponding to the city.

[0014] As shown in Table 1, the preset database includes a station label, a list of cities where the station is heard, and a list of FM channel information in the city where the station is heard. In this embodiment, music channel and financial channel are taken as examples. Music channels can be listened to in Shanghai, Hangzhou, and Nanjing. The listening frequency in Shanghai is FM101.7, the l...

Abstract

The invention discloses an automatic channel selection module for a radio, which is arranged on a mobile terminal. The automatic channel selection module comprises a database module and a searching module, wherein, the searching module is used for searching broadcasting channels of corresponding radio stations in different cities in the database module. The invention further discloses a channel selection method of the automatic channel selection module for the radio, which comprises the following steps: S1, the mobile terminal records the listening frequencies of the current radio stations of departure places and the cities; S2, the mobile terminal acquires new city names by network terminal interaction while roaming occurs; and S3, the searching module searches corresponding listening channels in the cities retrieved by the same station captions in step 2 in the database module. In the invention, the mobile terminal can directly call frequency signals of the corresponding local radio stations while roaming occurs, so a user is not interrupted in listening when the radio searches the signals and can listen more smoothly.

Description

technical field [0001] The invention relates to a radio automatic channel selection module and a channel selection method thereof, in particular to a radio automatic channel selection module and a radio channel selection method suitable for mobile terminals such as mobile phones. Background technique [0002] Now, more and more mobile phones are equipped with radio functions, and the current mobile phone radios are mainly frequency modulation (FM) and amplitude modulation (AM) systems. Among them, the sound quality of FM is better than that of AM, but it has the disadvantage of short transmission distance. When the mobile terminal is switched from one city to another, the frequency modulation of the same program may have changed. For example, when crossing the border between two adjacent provinces, the same channel cannot be played continuously and clearly, and the radio must search again in different places. Find the corresponding channel, during which the user cannot list...
