User terminal state be it is static, detection module 702 continues to test the state of user terminal.
Third determining module 705 obtains itself movement speed, when judging whether movement speed is greater than threshold value, if so, really
Surely the starting period for starting global positioning system is the first preset duration, if not, it is determined that start opening for global positioning system
The dynamic period is the second preset duration, and the first duration is less than the second duration;
Or,
Third determining module 705 speculates destination region according to motion profile, judges that destination region is with target geographical area
It is no to there is coincidence, if so, determining that the starting period of starting global positioning system is preset third duration, if not, it is determined that
The starting period for starting global positioning system is the 4th preset duration, and third duration is less than the 4th duration.
In the starting period that correction module 706 is determined according to third determining module 705, starting global positioning system is to generation mould
The motion profile that block 704 generates is modified.
The starting period is the first preset duration, the second preset duration, preset third duration or preset the
Four durations.
After 4th determining module, 707 correction motion track, user's end position is determined according to revised motion profile.
Judgment module 708 judges whether user's end position is in target geographical area, if so, execution module 709 executes
Prompting function if it is not, then processing module 710 closes global positioning system, and triggers the second determining module 703.
The mode for executing prompting function can be pop-up, vibration or jingle bell, can also be other modes, not make herein specific
It limits.
It is apparent to those skilled in the art that for convenience and simplicity of description, the system of foregoing description,
The specific work process of device and unit, can refer to corresponding processes in the foregoing method embodiment, and details are not described herein.
In several embodiments provided herein, it should be understood that disclosed system, device and method can be with
It realizes by another way.For example, the apparatus embodiments described above are merely exemplary, for example, the division of unit,
Only a kind of logical function partition, there may be another division manner in actual implementation, such as multiple units or components can be with
In conjunction with or be desirably integrated into another system, or some features can be ignored or not executed.Another point, it is shown or discussed
Mutual coupling, direct-coupling or communication connection can be through some interfaces, the INDIRECT COUPLING of device or unit or
Communication connection can be electrical property, mechanical or other forms.
The unit as illustrated by the separation member may or may not be physically separated, aobvious as unit
The component shown may or may not be physical unit, it can and it is in one place, or may be distributed over multiple
In network unit.It can select some or all of unit therein according to the actual needs to realize the mesh of this embodiment scheme
's.
It, can also be in addition, the functional units in various embodiments of the present invention may be integrated into one processing unit
It is that each unit physically exists alone, can also be integrated in one unit with two or more units.Above-mentioned integrated list
Member both can take the form of hardware realization, can also realize in the form of software functional units.
If the integrated unit is realized in the form of SFU software functional unit and sells or use as independent product
When, it can store in a computer readable storage medium.Based on this understanding, technical solution of the present invention is substantially
The all or part of the part that contributes to existing technology or the technical solution can be in the form of software products in other words
It embodies, which is stored in a storage medium, including some instructions are used so that a computer
Equipment (can be personal computer, server or the network equipment etc.) executes the complete of each embodiment the method for the present invention
Portion or part steps.And storage medium above-mentioned includes: USB flash disk, mobile hard disk, read-only memory (ROM, Read-Only
Memory), random access memory (RAM, Random Access Memory), magnetic or disk etc. are various can store journey
The medium of sequence code.
The above, the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations;Although referring to before
Stating embodiment, invention is explained in detail, those skilled in the art should understand that: it still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features;And these
It modifies or replaces, the spirit and scope for technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution.
