Description
Technical field
The present invention relates to data service technical field, relate in particular to geographical position synchronous method, Apparatus and system between a kind of terminal.
Background technology
GPS is a prerequisite basic ability on increasing cell phone apparatus; Navigation software and map software are application and the abilities having on more and more mobile phones.
Do you between terminal equipment, after all having had GPS ability each other, how to know the other side's geographical position? for example go on a tour to go with and drive, before and after how knowing by mobile phone, geographical position is avoided with losing or going to the wrong way each other; For example have a dinner party, go in way, dining room, how we know stroke place each other.
Synchronous for the real-time geographic position in motion, suppose to have terminal A and terminal B, several implementations that we can see are at present:
One, have the ability of architecture due to operator, geographical location information is roughly known in the base station that can connect by mobile phone or terminal.Terminal A is to the geographical location information of the inquiry terminal B of operator, and operator is confirming after the service order of terminal B or license in real time, feeds back to terminal A and wants to know the longitude and latitude geographical location information of target or the geographic position name of process translation.In reality, can see that this inquiry mode is note.
Two, existing common this class thing such as GPS+GPRS vehicle monitoring system or drive recorder, that each terminal (vehicle-mounted or non-vehicle-mounted) is registered longitude and latitude geographical location information own and submission oneself by GPRS network on certain station server, GPRS network and the Internet that geographic position data has passed operator arrive server, thereby the longitude and latitude geographical position of each terminal can be learnt by Surveillance center.
This requires server to possess the public network IP address of normalization, and terminal equipment must configure the ability of pointing to this IP address.Thereby further, terminal A can learn the geographical location information of target to remote monitoring center inquiry.Only in reality, using the terminal of such system, generally do not have demand need to know the geographical position of other terminal, is only that Surveillance center need to know all; But from technological layer, can accomplish.
Three, terminal A is initiated geographical position inquiry or initiatively the geographical position of oneself is informed to terminal B by short message mode; Adopt special messaging format and the identification of applying by note, the geographical position of carrying out longitude and latitude by navigation software or map software presents or geographic position name translation; And auxiliary with knowing ability in the geographical position that the modes such as mandate limit the other side.
In prior art, between terminal, real-time geographical position synchronously mainly contains following defect:
(1) aforesaid way one, an internuncial role has played in operator, is suitable for the scene of target geographic position under once in a while static inquiry, needing real-time update or follow the trail of in the moving scene in geographical position, can cause the cost of note too high, and store-and-forward mechanism have time delay possibility; Architecture precision is limited, needs only target in the coverage of same base station, and the variation in geographical position is just difficult to embody so; It in current realization, is PULL mode and fail to accomplish PUSH mode.
(2) aforesaid way two, an internuncial role has played in Surveillance center, in for moving scene, has solved Cost Problems in the mode of bit stream; Having solved positioning precision problem with GPS location, still, can only be PULL mode and can not PUSH mode, because the IP of terminal is for server or unknowable or normal variation; Need server and public network IP address, and the particular terminal of energy configuration of IP sensing.Have high input, be applicable to specific industry or unit.For the common people's simple requirements, for mobile phone terminal, significant discomfort is closed; Need to there is go-between to the common people's general requirements, but just existing problems of geographical position privacy.
(3) aforesaid way three, adopts by the mode of note, is to initiate short message enquiry by terminal A, is completed and is resolved that note, GPS geographical position are obtained, the process of feedback geographical location information by terminal B; Or terminal A initiatively send geographical location information to terminal B.The method does not have specific go-between, it is the P2P mode between terminal, geographical position precision is also guaranteed, but it is suitable for the scene of target geographic position under static once in a while inquiry equally, for needing real-time update or following the trail of the moving scene in geographical position, same, continuous transmission note cost is too high and store-and-forward mechanism has the possibility of time delay.
If in such a common scene: certain outdoor association/a group good friend, people to certain objective set, need location aware from different cities each other.Existing GPS equipment is in a world by oneselfly cannot know mutually also there is no the such service in the Internet of company level, and the mutual real-time official post in note position is with also inconvenient, and many human world are not stopped paying out and sent note not only expense is high, certain mobile phone also will be set and do center.Therefore it is synchronous that, above-mentioned three kinds of modes all cannot realize geographical position between the terminal in this scene.
