Patent number: 11002822Abstract: A near field communication (NFC) mobile device may obtain location information from a NFC terminal device that is communicating with the NFC mobile device. A data transfer link may be established between the NFC mobile device and a mobile telecommunication network. The mobile telecommunication network may prompt the NFC mobile device to obtain location information from the NFC terminal device. The mobile telecommunication network may then receive the location information from the NFC mobile device via the data transfer link, and may subsequently determine a location of the NFC mobile device using the location information.Type: GrantFiled: December 31, 2018Date of Patent: May 11, 2021Assignee: T-Mobile USA, Inc.Inventors: Magesh Annamalai, Zhengyi Jin, Shreenivas M.

Patent number: 10716085Abstract: A system and method determines a geographic position of a mobile device in communication with an IP-based wireless telecommunications network. A wireless connection between the mobile device and the IP-based wireless telecommunications network is established when the mobile device registers with a network controller (NC) through an access point (AP). When a geographical position is needed for the mobile device (e.g., a 911 call), messages are exchanged between the NC and the SMLC where the SMLC retrieves information from a database that is used to identify the geographic position of the mobile device. The database can store a variety of information related to mobile devices such as: last known position, IP address, MAC address, device or subscriber identifier, last CGI, etc. The geographical position is communicated back to the NC, which can then forward the position information to a switch for processing such as for 911 calls.Type: GrantFiled: May 22, 2017Date of Patent: July 14, 2020Assignee: T-Mobile USA, Inc.Inventors: Magesh Annamalai, Zhengyi Jin

Patent number: 8737311Abstract: A system and method for mitigating the delay associated with using GPS technologies to determine the location of a mobile device. The system utilizes a two-stage location determination process. During the first stage, an estimated position of the mobile device is immediately provided based on the most accurate stored location information that is available to the system. If greater accuracy is still required, during the second stage a more accurate position of the mobile device is provided using GPS-based technologies.Type: GrantFiled: February 5, 2013Date of Patent: May 27, 2014Assignee: T-Mobile USA, Inc.Inventors: Zhengyi Jin, Magesh Annamalai
