FACILITATING LOCATION DETERMINATION IN A CELLULAR COMMUNICATIONS SYSTEM |
摘要 |
<p>An Internet protocol (IP) based location system that employs a global positioning system (GPS) component in connection with a position determining entity (PDE) component to determine location of target mobile station(s) via the Internet. As such the system provides an internet protocol based scheme (e.g., UDP) to initiate a location determination session within a CDMA network. The system can provide a location determining service even when the mobile station(s) are not within a home network (e.g., roaming situations). The system can also employ HTTP over TCP/IP so as to facilitate communications between the mobile station(s) and a mobile positioning center (MPC) (e.g., authentication and/or security protocols/schemes). Furthermore, the system can identify a PDE of a plurality of available PDEs that is most suitable for a given state of the mobile station and/or state of the user and/or particular location based application being employed by the mobile station.</p> |
