Embodiment
To make the objects, technical solutions and advantages of the present invention clearer, clear and definite, develop simultaneously embodiment pair referring to the drawings
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and without
It is of the invention in limiting.
The method that mobile terminal described in present pre-ferred embodiments loads FM parameters automatically, as shown in figure 1, a kind of mobile
The method that terminal loads FM parameters automatically, comprises the following steps：
Step S100, when mobile terminal start FM search when, by GPS location obtain mobile terminal where positional information so as to
Obtain the country code in location.
Also include before the step S100：
Step S000, advance layer FM_SERVICE on mobile terminals（Frequency modulation is serviced）In set up country variant code and FM and join
Several relation tables.It is easy to, when user reaches different national or areas, the country code in location be obtained by mobile terminal
When, the country code that location is inquired about by the country variant code and the relation table of FM parameters that pre-set whether there is institute
State in relation table, local FM parameter settings are carried out if there is user just can be facilitated.
There are customized FM parameters in the different country in the whole world, wherein including band limits, step size, intermediate frequency size letter
Breath, band limits is the hunting zone that FM radios are used, and step size is the frequency size threshold value that FM is searched for every time.
For example, setting up the relation table of country variant code and FM parameters in advance layer FM_SERVICE on mobile terminals
It is as follows（It is only for example, it may include the FM parameters in more countries or area）：
| Region | Country code | Frequency range | Stepping | Intermediate frequency |
| China | CN | 87.5-108MHZ | 50KHZ | 10.7MHZ |
| Russia | RUS | 87.5-108MHZ | 50KHZ | 10.7MHZ |
| Japan | JP | 76-90MHZ | 100KHZ | 10.7MHZ |
| The U.S. | USA | 87.5-107.9MHZ | 200KHZ | 10.7MHZ |
The step S100 specifically includes following steps：
Step S101, mobile terminal start FM search, mobile terminal backstage pass through GPS location obtain location longitude and latitude believe
Breath；
Step S102, by latitude and longitude information obtain national geography positional information, so as to obtain the country code in location.
Specifically, when mobile terminal opens FM search, mobile terminal backstage obtains longitude and latitude by GPS location and believed
Breath, or GPS latitude and longitude information of the reading system to store, by latitude and longitude information, obtain national geography positional information, obtain state
Family's code.For example, being by GPS location acquisition latitude and longitude information longitude and latitude：2301.9334, N, 11420.9604, E, the then ground
Managing positional information is：Guangdong province, China Huizhou Zhong Kai high and new technology industrial development zones A roads B buildings, then understand correspondence country by inquiring about above-mentioned relation table
Code is China CN, 86.
Step S200, the relation table by inquiring about country variant code and FM parameters, judge that the country code got is
It is no to be present in the relation table.
The step S200 specifically includes following steps：
Step S201, by the country variant code and the relation table of FM parameters that pre-set the country code got is carried out
Inquiry；
Step S202, after the completion of inquiry, judge that the country code that gets whether there is in the relation table.
Specifically, what such as the example above was mentioned obtains latitude and longitude information longitude and latitude by GPS location is：2301.9334,
N, 11420.9604, E, then the geographical location information be：Guangdong province, China Huizhou Zhong Kai high and new technology industrial development zones A roads B buildings, correspondence country code
For Chinese CN, 86, in MTK（Media Tek, MTK platforms use the Android system of main flow）On FM radios in platform
Relation table is read in layer service, gets frequency range for 87.5-108MHZ, step size is 50KHZ, and intermediate frequency size is
10.7MHZ, transfers HAL（Hardware Abstract Layer, i.e. hardware abstraction layer, HAL effect is by operating system
Remainder is expressed as abstract hardware device, particularly eliminates flaw and speciality that real hardware is rich in, mainly uses
In handle different platform between transplant compatibility the problem of）Layer services radio.fm.mt6737m.so, corresponding for setting
Parameter interface.
Step S300, if obtaining the corresponding FM parameters of the country code in the presence of if, and control driving layer that the state is set
The corresponding FM parameters of family's code；If being not present, load default parameters and pointed out.
The step S300 specifically includes following steps：
If step S301, the country code got are present in the relation table, the corresponding FM ginsengs of the country code are obtained
Number, the FM parameters include the information of band limits, step size and intermediate frequency size；
Step S302, mobile terminal upper strata FM_SERVICE control driving layer are according to the band limits, step size got
And the information of intermediate frequency size sets the corresponding FM parameters of the country code；
If step S303, the country code got are not present in the relation table, default parameters is loaded and mobile whole
Hold and frame prompting user is played on screen.
Specifically, when the country code got（Guangdong province, China Huizhou Zhong Kai high and new technology industrial development zones A roads B buildings, correspondence country code
For Chinese CN, 86）It is present in the relation table, obtains the corresponding FM parameters of the country code, the FM parameters includes frequency
The information of segment limit, step size and intermediate frequency size（Frequency range is got for 87.5-108MHZ, step size is
50KHZ, intermediate frequency size is 10.7MHZ）, by transferring HAL layers of service radio.fm.mt6737m.so, corresponding parameter is set
Interface, so as to pass to driving layer, driving layer gets parms, and the related FM registers of control set FM parameters, facilitate user to make
Radio reception is carried out with the FM in location, is provided the user conveniently.
Based on above method embodiment, present invention also offers the system that a kind of mobile terminal loads FM parameters automatically, such as
