Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
Referring to Fig. 1, present embodiment provides a kind of method of portable terminal Passive Positioning, comprising:
101: portable terminal judges whether time interval of reaching default;
Wherein, portable terminal can be a mobile phone etc. specifically, and present embodiment does not limit.
102: if reach this time interval, obtain locating rule information, this locating rule information comprises the location start information and submits positional information to;
Wherein, distribution site specifically can be a server.
103:, obtain the positional information of self according to this location start information;
104: self the positional information that will obtain is submitted to the position of this submission positional information correspondence.
The method that present embodiment provides, portable terminal is reaching under the situation in default time interval, initiatively obtain the locating rule information that comprises the location start information and submit positional information to, according to the location start information, obtain the positional information of self, and self positional information is submitted to the position of this submission positional information correspondence, realized a kind of Passive Location that need not carry out special identifier and modification to the OEM layer, and saved links such as the authentication of Location Request and forwarding, alleviated the load of server.
Referring to Fig. 2,, introduce the method for above-mentioned portable terminal Passive Positioning in detail below in conjunction with instantiation.
201: when portable terminal is in open state, judge whether the time interval that reaches default; If reach, execution in step 202 or step 203, otherwise repeated execution of steps 201;
Also promptly, step 202 is optionally, direct execution in step 203 after the step 201.
Wherein, the time interval can be made as n minute, and n is a natural number.
202: obtain the note in self short message inbox, and check whether the note that comprises the Location Request form is arranged in the note, if having, execution in step 203 is also deleted note, otherwise repeated execution of steps 201;
Concrete, the ITAPI interface that can pass through BREW (Binary Runtime Environment for Wireless, vedio on radio binary operation environment) platform obtains the note in self short message inbox, and present embodiment does not limit the physical interface that obtains note.
Wherein, binary runtime environment for wireless is the resident framework that develops software of a CDMA (Code-Division MultipleAccess, code division multiple access) portable terminal that QualCom provides.
203: obtain locating rule information, it comprises the location start information and submits positional information to;
Concrete, when execution in step 202 not, can obtain locating rule information from distribution site by the IWeb interface and the ISocket interface of binary runtime environment for wireless, present embodiment does not limit the physical interface that obtains locating rule information; When execution in step 202, can obtain locating rule information from the note of short message inbox by the ITAPI interface of binary runtime environment for wireless, also can obtain locating rule information from the distribution site of acquiescence, present embodiment does not limit concrete obtain manner and interface.
Wherein, distribution site can be a server specifically, and establishing its address in the present embodiment is request_URL.
Wherein, the location start information can be that the location begins sign or interval, location.The location begins sign and is used for the single-point location, and whether expression begins one-time positioning, is made as position_flag in this example.The location is used for the continuous path location at interval, and expression is the location interlude continuously, is made as interval in this example.
Wherein, submitting to positional information to represent the position that portable terminal is submitted the positional information of self to, can be the address of equipment such as server or terminal, is made as response_URL in this example.
Wherein, can set up HTTP (Hypertext TransferProtocol, HTML (Hypertext Markup Language)) when distribution site obtains locating rule information connects.
204:, judge whether to begin Passive Positioning according to this location start information;
Concrete, when the location begins to be designated true time, perhaps when reaching the interval, location, then beginning the Passive Positioning process, execution in step 205 then, otherwise return step 201.
205: open HTTP and connect;
Concrete, can open HTTP with the ISocket interface by the IWeb interface of binary runtime environment for wireless and be connected, present embodiment does not limit opens the physical interface that HTTP connects.
206: portable terminal initiatively obtains the positional information of self;
Concrete, portable terminal can obtain the positional information of self by the IPosDet interface of binary runtime environment for wireless, and present embodiment does not limit the physical interface that obtains self positional information.Wherein, positional information can be GPS (Global Positioning Systems, a global positioning system) positional information, can be stored in the gps_position variable.
207: self the positional information that will obtain uses the POST method to be submitted to the position of this submission positional information response_URL correspondence.
Then, execution in step 201 again, begin the process of another Passive Positioning, and this is a cyclic process, does not repeat them here.
For the method for present embodiment more clearly is described, provide a kind of false code algorithm of realizing this method below, this false code algorithm only is the aid illustration of present embodiment, not in order to limit the present invention.
