Step S501: the operator selects BREW or GPS car-mounted terminal to initiate the single location on client browser, client is sent the latest position request of obtaining according to the interval (generally being configured to 5 seconds) of appointment to the service processor 203M that service is provided after sending Location Request.Herein, described service processor 203M is meant the operational processor into selected Terminal Service.
In the latest position result still before the no show service processor 203M, what client obtained is old positional information in the past, client is right according to time ratio in current time and the position result, discovery is old position, then on the map of client, do not show, and continue to send and obtain the latest position request to service processor 203M.
Step S502: the service processor 203M that service is provided sends to communication server 204, and generates the note ticket according to terminal type structure single positioning instruction.
Step S503: communication server 204 carries out protocol adaptation (for example carrying out the SGIP/CMPP/SMGP/SMPP protocol adaptation), and the short message that is configured to comprise the single positioning instruction is a Submit message, sends to Short Message Service Gateway (or sms center).
Step S504: Short Message Service Gateway is delivered note to sms center, by No.7 nation-wide Network send comprise the single positioning instruction short message on terminal, the built-in terminal program 205 of terminal positions mutual to obtain the current location of terminal with navigation system.
The Brew terminal program calls the Brew interface and initiates the GpsOne positioning flow, gets access to the current location result by MPC.The GPS car-mounted terminal can be directly and satellite obtain current location alternately.
Step S505:Brew terminal program arrives communication server 204 with position result by the direct reported result of packet data node; GPS car-mounted terminal program is assembled into a note with position result and is reported to sms center, and sms center is delivered to Short Message Service Gateway, is delivered to communication server 204 again.
