The broadcasting stations are used as a wide propagation medium, along with the rich and colorful life styles of people, the broadcast contents are more and more wonderful, the number of the broadcasting stations is more and more, and therefore, the types of the broadcasting stations which can be selected by people are more and more. FM radio has long been integrated in mobile communication, and today's car terminals are basically equipped with FM radio, which is also one of the functions frequently used by users.
With the richness of radio stations and the expansion of the activity range of people, the number of the radio stations which can be heard in the vehicle-mounted terminal is more and more, and people need to search the radio stations and switch among different radio stations so as to find favorite radio station programs. However, in the conventional wireless communication devices of today, the best radio program cannot be recommended to the user according to different places and different times, each time the user turns on the radio, the turned-on radio is the radio that was turned off by the user last time, and the user can only adjust the radio program to be heard by a manual mode. Therefore, basically, when a user starts the radio station, the user needs to perform manual adjustment every time, and the efficiency of using the radio station by the user is influenced; meanwhile, the conventional method cannot record the radio programs which the user likes to listen to, and the user is likely to miss the favorite radio programs after the user turns on again.
The relation between the radio program and the current time and place is large, namely the radio program which needs to be listened by the user is different at different times, for example, the radio program listened by the user at 8 to 9 points is different from the radio program listened by the user at 13 to 14 points; similarly, the radio programs that the user needs to listen to are different from one another in different locations, such as when the user listens to one program in the sea, and in suzhou, the user wants to listen to another program, and when the user's geographical location changes, the program that was listened to when the user last closed is likely to be inaudible. Therefore, the selection of the default station when the current station is started brings inconvenience to the user.
The radio application user of the vehicle-mounted terminal has higher use frequency, if the radio is played before the user stops playing, the radio can be resumed after the vehicle is started next time, but the radio which is played before the user stops playing is generally resumed, and is not the radio which is liked by the user.

In addition, the present embodiment may also perform automatic selection or implement security performance such as authentication for different users, and therefore, in a preferred embodiment, the present embodiment may further include: the database also stores the characteristic information of the user, and the characteristic information of the same user is bound with the recommendation information of the user so as to obtain the corresponding recommendation information according to the characteristic information of the user; the feature information comprises one or any combination of face feature information, fingerprint feature information, voiceprint feature information and iris feature information.
In a similar way, the application further provides a vehicle, and the vehicle is provided with the vehicle-mounted terminal, so that the radio station starting recommendation method can be further realized.
In some embodiments, since the radio stations and the geographical locations have a great relationship, the radio programs heard at different geographical locations are also different, and even if the frequency is the same, different geographical locations correspond to different radio programs, so that in order to enable the statistical information of the radio stations to be stored, the radio stations at different geographical locations need to be stored separately. When a user arrives at a new place, the method can automatically search the radio stations at the current geographical position, the radio station information is stored in a radio station list, meanwhile, each radio station list has a category mark for representing different geographical positions of the radio station list, and the new position information can be automatically acquired each time the user starts the radio station or searches the radio station.
In addition, because the radio programs and the time slots have a great relationship, the radio programs played in different time slots are also different, and the radio stations listened to by the user in different time slots may also be different, therefore, after the radio station list of the current geographical location is determined, the radio station listening conditions of each time slot in the radio station list need to be respectively counted, and the radio station listening time length is ranked according to the radio station listening time length, and the longer the listening time of a certain radio station in a certain time slot is, it is indicated that the radio station is the radio station that the user prefers to listen to in the certain time slot. Therefore, in each time slot, the radio stations are sorted from large to small according to the listening time length of the radio stations, a sorted list is established, and the radio station program arranged at the top of the sorted list is the optimal target radio station of the time slot.
For example, the time of day may be divided into different time periods in the present embodiment, for example, considering that the radio programs are mostly changed at the hour, i.e. 8 to 9 are one type of programs, and 9 to 10 are another type of programs, so that each hour is taken as one time period in the present embodiment, and 24 hours per day is divided into 24 time periods: 0 to 1, 1 to 2, etc. In order to enable the radio programs to be statistically sorted in each time slot, in this embodiment, each time slot has a corresponding number of radio station sorted lists, each sorted list stores radio station information corresponding to different geographical locations, and the number of the sorted lists corresponding to each time slot is consistent with the number of different geographical locations stored by a user, that is, after the user stores radio station information of 5 geographical locations, each time slot has 5 sorted lists corresponding to the time slot, and each sorted list corresponds to one geographical location. Of course, in order to save the storage space, each node in the sorted list corresponding to the time period only stores the serial number of the station in the station list and the listening time of the listening, and the station information can be obtained from the stored station list through the station serial number of the node.
It is worth mentioning that when the time of a certain radio station listened to by the user is a time span period, for accuracy of statistics, the time span needs to be respectively counted into different time spans, for example, when the user listens to the C radio station from the time span 1 to listen to the time span 2, then the time span of listening to the C radio station in the time span 1 needs to be counted into the sorted list of the time span 1; where the length of time during time slot 2 for listening to the C program needs to be counted in the ordered list to time slot 2. Thus, when a program is time-span, the statistical result will advance the ranking of the station program in both time periods, thereby making the statistical accuracy higher.
It is worth noting that the vehicle-mounted terminal of the embodiment can adopt a 5G technology, for example, the 5G internet of vehicles is used for realizing network connection between the vehicle-mounted terminal and the cloud database, the 5G technology adopted by the embodiment can be a scene-oriented technology, the vehicle (especially an intelligent internet automobile) is supported by the 5G technology, a connector or a connecting vehicle is realized at the same time, and the following three typical application scenes can be adopted for forming.

the third is mMTC (mass machine type communication), and the main index which can be realized by the application is the connection number density, 100 ten thousand other terminals are connected per square kilometer, and the connection number density is 10^6/km 2.

1. the radio frequency, the radio name, the playing time, the position, the current program name and the listening time of the user which are currently played are recorded in real time and transmitted to the cloud end through a network (such as a 5G Internet of vehicles).
2. The cloud end can provide corresponding real-time statistical analysis module, and the user who listens to the radio station record to the record carries out real-time analysis statistics, carries out statistical analysis according to a time quantum every half an hour, and statistics this time quantum user listens to the radio station frequency or the program name of duration the most, and this information can be according to the incessant change of user's listening habit to real-time statistical analysis.
3. The cloud provides a corresponding prediction module, so that the user listening behavior in a certain time period and a certain position can be predicted, and the main prediction mode is that the radio station or program which is most listened by the user and is obtained through the real-time statistical analysis is used as recommendation information.
4.
