Step S201: the user carries out user's registration by terminal;
This preferred embodiment adopts the form registration of " user name+password+other log-on messages ", specifically comprises: the user is at the log-on message of client input oneself; Client sends to share service device end with log-on message; After the share service device terminates to user's log-on message, preserve its information, and distribute buddy list (at the beginning of the registration, buddy list is empty) for it; Server returns to the client server end with registering result (success or failure);
If the user registers, then directly skip this step, enter subsequent step.
Step S202: the user signs in to the share service device by terminal;
Specifically comprise: the user is at the username and password of client input oneself; Send logging request to the share service device; The share service device receives login request of users, confirms that user's login record user's logging status is a "Yes", then returns the login result and gives client; Client receives return results, prompting " logining successfully " or " login failure ".
Step S203: the user is provided with Share Permissions by terminal;
The locus Share Permissions that comprises this terminal is set to " permission " or " forbidding ", and, allow to share user's (terminal) tabulation of this terminal locus.
Step S204: obtain current spatial positional information, carry out necessary processing;
To the spatial positional information that obtains by the GPS locating module, need carry out migration processing to accessed longitude and latitude, to meet the relevant pressure standard-required of country.
This spatial positional information can also be put the mode of taking from own position by the user and obtain on electronic chart, this spatial positional information only comprises longitude and latitude, and deflection is empty.
Step S205: the spatial positional information after will handling is uploaded to the share service device;
Step S206: the share service device is preserved after with the spatial positional information additional hours effective information that receives;
This age information is the time that the share service device is successfully received the spatial positional information that a terminal is uploaded, and the form of temporal information is " a date Hour Minute Second ", as 13:34:29 on Dec 23rd, 2010.
Need to prove that in this preferred embodiment, age information is additional by the share service device; In specific implementation process, also can select by the relevant age information of terminal additional.
Step S207: terminal sends the spatial positional information download request to the share service device;
Step S208: the share service device mates according to the Share Permissions that the user is provided with, and obtains the spatial positional information that this terminal has all terminals of Share Permissions;
Step S209: terminal receives the spatial positional information that the share service device sends;
Step S210: sign or refresh the correlation space positional information on electronic chart;
Repeat above-mentioned steps S204～S210 by the default time interval, can realize that the locus between the terminal is shared.
