Embodiment Construction

[0024] In the following, the terminal A actively sends its geographical location information to the terminal B as an example in conjunction with the accompanying drawings to describe the mutual location knowledge between multiple terminals or even dozens of terminals, so as to explain the present invention in detail. In the example, it is assumed that the APN used is "CMGPS", and the format of the data packet protocol used is "cmgps: / / mobile number / geovalues? Mobile number 1 = geographic location and time 1 & mobile phone number 2 = geographic location and time 2". Of course, the name and protocol name of the APN and the content format can be defined according to the actual situation.

[0025] The main network elements involved in this embodiment include: GPRS Serving Support Node (ServingGPRS SUPPORTNODE, SGSN) and Gateway GPRS Support Node (Gateway GPRSSupport Node, GGSN).

[0026] Such as figure 1 As shown, when terminal A and terminal B are in the same service area, the e...

Abstract

The invention discloses a method, a device and a system for synchronizing the geographical position between terminals. A specific communication channel is established to transmit geographical position information between the terminals, and the terminals can exchange the geographical position information in a P2P mode with no need for a special mediator. No investment on servers, IP addresses and special terminal is needed, and ordinary terminals can be adopted to receive and transmit the geographical position information. Cost on synchronization of the geographical position between the terminals is low, real-time performance is strong, and geographical position accuracy is high.

Description

technical field [0001] The present invention relates to the technical field of data services, in particular to a method, device and system for synchronizing geographic locations between terminals. Background technique [0002] GPS is a basic capability that more and more mobile devices must have; navigation software and map software are applications and capabilities that more and more mobile phones have. [0003] How can terminal devices know each other's geographic location after each other has GPS capabilities? For example, when traveling and driving together, how to use the mobile phone to know the geographical location of each other to avoid losing or going the wrong way; for example, how do we know each other's itinerary on the way to the restaurant for a dinner party. [0004] For real-time geographic location synchronization in motion, assuming there are terminal A and terminal B, several implementation methods we can see at present are: [0005] 1. Because the oper...
