For making object of the present disclosure, technical scheme and advantage clearly, below in conjunction with accompanying drawing, disclosure execution mode is described in further detail.
The disclosure one exemplary embodiment provides a kind of method of frequency band search, and this method embodiment is applied in terminal, and see Fig. 1, method flow comprises:
In a step 101, time zone corresponding to terminal present position is obtained;
In a step 102, in the corresponding relation of time zone and the frequency range preset, the frequency range that acquisition time zone is corresponding;
In step 103, corresponding according to time zone frequency range carries out frequency band search.
Disclosure embodiment by obtaining time zone corresponding to terminal location, and obtains frequency range corresponding to time zone corresponding to current location in the corresponding relation being region frequency range, in the frequency range got, carry out frequency band search.Reduce the hunting zone that terminal carries out frequency band search, consequently reduce the time that terminal searching frequency range consumes, improve the efficiency of search frequency range.
Another exemplary embodiment of the disclosure provides a kind of method of frequency band search, and this method embodiment is applied in terminal, and see Fig. 2, method flow comprises:
In step 201, time zone corresponding to terminal present position is obtained.
In the disclosed embodiments, time zone corresponding to terminal home position describes with the first time zone, and the corresponding after moving to a new location time zone of terminal describes with the second time zone, and the time zone that namely the current present position of terminal is corresponding is the second time zone.
Determine that the mode in the second time zone can include but not limited to following two kinds of modes in this step:
First kind of way, step 201 can determine the second time zone as follows:
In step 2011, obtain the positional information that terminal is current.
In this step, terminal can be positioned by the locating module calling self, the mode of wherein locating can include but not limited to: GPS (GlobalPositioningSystem, global positioning system) locates, and architecture and GPS and base station position jointly.Wherein, positional information can include but not limited to longitude and latitude.
In step 2012, in the corresponding relation in positional information and the time zone of presetting, the time zone that acquisition positional information is corresponding.
The second way, step 201 can determine the second time zone as follows:
In step 2013, obtain the very first time before terminal regulation time and the second time after regulation time, and calculate the time difference between the very first time and the second time.
Wherein, the time that the first time zone is corresponding is the very first time.After user's carried terminal moves to new position, can arrange the system time of terminal, to be the local time by the system time setting of terminal, the system time setting by terminal was the second time.
Now, obtain this second time when the system time of user to terminal is arranged, record the very first time before arranging simultaneously.
Such as: user goes to New York to go on business from Beijing, the first time zone before going on business accordingly in terminal is Dong eight district, place, Beijing, the system time of user's terminal when arriving New York is Beijing time (very first time) 20:00, and user is arranged according to the system time of local time (the second time) 7:00 to terminal.Wherein, the time difference of the very first time and the second time be the very first time more Zao than the second time 13 little time.
In step 2014, according to the time zone before time difference and terminal regulation time, determine the time zone after terminal regulation time.
