| 20090177730 | SYSTEM AND METHOD FOR DETERMINING DEVICE LOCATION IN AN IP-BASED WIRELESS TELECOMMUNICATIONS NETWORK - 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. | 07-09-2009 |
| 20100046406 | MOBILE COMPUTING DEVICE GEOGRAPHIC LOCATION DETERMINATION - A wireless connection between a mobile device and an 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 a serving mobile location center (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, a mobile or subscriber identifier (such as an International Mobile Subscriber Identity (IMSI)), 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. | 02-25-2010 |
| 20100289640 | MOBILE DEVICE LOCATION DETERMINATION USING MICRONETWORKS - A facility for determining the location of a mobile device when a location determination of a desired accuracy is desired. If available, the facility determines the location of the mobile device using a device-based technique or using a location determination technique that is accessible over a macronetwork. Macronetworks are networks that are designed to cover relatively large areas. If a location determination technique of desired accuracy is not available on the device or over a macronetwork, the facility attempts to use a location determination technique that is accessible over a micronetwork to determine the location of the mobile device. Micronetworks are networks that are designed to cover smaller areas. By forcing a switch from a macronetwork-based location determination technique to a micronetwork-based location determination technique, the facility ensures that a location determination is made for the mobile device of a desired accuracy, time to fix (TTF), and/or yield. | 11-18-2010 |
| 20100291947 | FACILITY FOR SELECTING A MOBILE DEVICE LOCATION DETERMINATION TECHNIQUE - A facility for selecting a location determination technique from multiple available location determination techniques in order to determine the location of a mobile device in a cost or resource efficient manner. In order to select the location determination technique, the facility may consider various criteria such as the cost of employing the techniques, quality of service (QoS) criteria, the capabilities and/or resources of given mobile devices and/or networks, and/or the like. To select the location determination technique, the facility may rank the multiple location determination techniques according to weighted criteria and select the location determination technique according to the ranking. The criteria may be weighted according to the relative importance of each criterion to a requesting location-based service. | 11-18-2010 |
| 20110051658 | TWO STAGE MOBILE DEVICE GEOGRAPHIC LOCATION DETERMINATION - 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. | 03-03-2011 |
