| description | 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. |
