Description

Method and device for updating radio channel

Technical field

The present invention relates to the field of communications, and in particular to a method and apparatus for updating a radio broadcast channel.

Background technique

With the gradual popularization of mobile terminals, more and more users have gradually transferred information from personal computers (PCs) to smart mobile terminals. However, gazing at the screen for a long time can cause severe eye fatigue in the user. The FM application on the mobile terminal is popular among users because of its high information update, various radio programs, convenient operation, and no need for the user to pay attention to the content displayed on the screen for a long time.

Most of the radio functions on the existing smart mobile terminals can implement basic functions such as searching, setting, and renaming channels. However, since the coverage distance of FM radio stations is very limited, stations in different cities have different frequencies. If the user leaves the current city and arrives at another place, the station he is listening to may become a fake station in a new place and cannot be listened to normally. Users must re-search for active stations throughout the entire frequency band, seriously affecting the user experience. Therefore, how can the terminal automatically detect the strength of the radio signal when detecting the change of the location information of the city, and search for the effective radio station in the full range in the background and switch, and automatically switch to the effective channel of the same type becomes a technical problem to be solved.

The solution provided in the related art is to open the radio for the first time, and the radio will automatically search in the full frequency band to obtain a list of effective channels; if it is not the first time to enter the radio, the user needs to manually search for the entire channel to update the existing channel list. . Users need to find and add tags themselves to listen to their favorite stations. Using this method will increase the complexity of the operation of the user to find the station and is more time consuming. Moreover, when the user transfers from another vehicle to another city from the current city, the previously listened to the radio station may become an invalid radio station, and then cannot be normal. Listening; the stations in the channel list that the original user searched for may not be able to listen properly in the new city.

To this end, two improved solutions have been proposed in the related art:

Solution 1. When the location of the city information changes, the scheme of the invalid channel in the channel information list can be automatically cleared. Although the scheme can ensure that there is no invalid station in the channel list, how should the invalid station information being played on the radio be processed? And how to replace it does not provide a clear solution;

In the second scheme, when the location information is detected to change, the channel in the same frequency modulation area under the new coordinates can be searched in the database for playing. This method can avoid the user listening to the invalid radio station after changing the city, but cannot judge. Whether the newly switched station is the type that the user likes to listen to.

In summary, the existing solution has the following two drawbacks:

Defect 1. The method of pre-storing channel information of different areas through the database, although the fake station information in the channel list can be eliminated when the position is switched, but how to deal with the invalid channel that the user is listening and how to select the next one for the user to play There are no explicit mentions of valid stations.

Defect 2. Although the existing scheme refers to finding the channel information in the same FM area under the new location coordinates for playback, how to select a new channel does not indicate that the channel searched in the new location area may not be the user who likes to listen. The radio still needs the user to manually search for the station that he wants to listen to, thereby increasing the user's operational complexity, which in turn seriously affects the user experience.

Step S104: Search for the same type of station as the listening station in the first area in the second area, and perform update play by using the same type of station.

In the related art, the radio cannot be normally listened after switching the city, and cannot meet the user's use requirements. Using the method shown in FIG. 1 , the city information is obtained according to the location location technology, and when the city information changes, the automatic station is automatically searched for the current station, and the current station is automatically switched to the search if the current channel is invalid. Come out on the same type of effective radio station. Users who use the radio in this way do not need to manually search for channels. It also enables the seamless conversion of the radio channel, while avoiding the user to perform complicated operations, but also enhances the user experience.

In a preferred embodiment, after the radio is turned on, the terminal queries the location information of the city in real time to classify the current station, for example: music, news, traffic, drama, agriculture and forestry, when the user switches from the current city to another city. Next, the terminal needs to perform the following two operations:

Operation 1. In the frequency band supported by the mobile terminal, the background automatically re-searches for a valid station, and the searched stations are classified and stored in a database;

Operation 2: Detecting the radio signal. If the signal is lower than the preset threshold, the current broadcast channel is an inactive channel in the city. Therefore, the same type of effective channel can be searched from the database for replacement play.

If the user listens to a music station in the previous city and travels to the next city on a specific vehicle and detects that the radio signal is too weak to listen, the radio can automatically search for the effective radio station in the full band in the background, no The seam is switched to the music station on the current city. This implementation can effectively prevent the user from cumbersomely re-searching for the radio station, and finds which music station is one by one in the channel list of the strange city. It not only satisfies the user's listening needs of the radio, but also simplifies user operations and enhances the user experience.

Preferably, in step S102, it is determined that the terminal switches from the first area to the second area and the signal strength is lower than the preset threshold after switching to the second area, and may further include the following operations:
