Location sharing and tracking using mobile phones or other wireless devices

A system for monitoring the location of individuals, such as parolees, includes a wearable device worn by the individual and a portable device operatively coupled to the wearable device. The portable device is operatively coupled to a monitoring system through a wireless telephone network. The portable device transmits periodically encrypted location information as well as status information across the wireless network to the monitoring system. The monitoring system tracks the location of the individual and alerts the appropriate authorities when the individual violates a rule, such as a condition for parole. The portable device increases the time between transmissions when the individual is within a specified home location and reduces the time between transmissions when outside the specified location.

Personal tracking device

The present invention is directed to a method of asset location. Location data is received from a cellular transmitter associated with a selected asset, which location data includes data representative of a cellular receiver with which direct communication with the cellular transmitter is made. The location data is then communicated to a tracking service system, which tracking service system includes a database representative of geographic locations associated with a plurality of cellular receivers. The database is then queried with received location data so as to generate geographic tracking data associated with a location of the cellular receiver, the geographic tracking data including display data adapted to generate a map image including a representative of a location of the selected asset. The geographic tracking data is then communicated to an associated security agency so as to allow for viewing of an image generated in accordance with the display data and at least one of tracking and interception of the selected asset.

Method and system for providing tracking services to locate an asset

Techniques to support emergency voice-over-Internet Protocol (VoIP) calls are described. The techniques may be used for various 3GPP and 3GPP2 networks, various location architectures, and various types of User Equipment (UE). A UE communicates with a visited network to send a request to establish an emergency VoIP call. The UE interacts with a location server instructed by the visited network to obtain a first position estimate for the UE. The UE performs call setup via the visited network to establish the emergency VoIP call with a PSAP, which may be selected based on the first position estimate. The UE may thereafter perform positioning with the location server to obtain an updated position estimate for the UE, e.g., if requested by the PSAP.

Voip emergency call support

An E-9-1-1 voice-over-IP (VoIP) solution is provided wherein a 911 call from a mobile VoIP device is routed directly to the correct Public Safety Answer Point (PSAP) via dedicated trunks, together with correct location information and call-back number. VoIP gateways are implemented locally, at least one per LATA, and accept VoIP packetized data inbound, and convert it to standard wireline voice calls. Calls are routed to an IP address at the VoIP gateway, which then egresses the call to a voice port at a selective router. Mid-call updating of location of a moving VoIP terminal is provided to a PSAP. The location of the VoIP is validated using HTTP based protocol by pushing location information to a VoIP location server, and comparing it against a geographic location database to confirm that a contained street address is valid.

SOLUTIONS FOR VOICE OVER INTERNET PROTOCOL (VoIP) 911 LOCATION SERVICES

A method and apparatus to facilitate the locating and tracking of a wireless terminal, which may be advantageously used for E-911 service. The terminal may be directed to transmit a beacon for certain events, such as in connection with a 911 call. The beacon has a specific format known by the wireless network, and may be periodically or continuously transmitted. The beacon may be transmitted using various schemes. In a first scheme, the terminal transmits the beacon only when directed to do so by a designated network entity (e.g., the PSAP). In a second scheme, the terminal transmits the beacon in conjunction with the 911 call, and is thereafter directed to terminate the beacon transmission by the designated network entity. The beacon allows the terminal to be accurately located even if it has moved or is physically located in an enclosed or “not-so-obvious” location.
