Cloud-Based Emergency Location Service

Abstract:

A method for a wireless UE device to utilize tokens and cloud service technology to facilitate the provision of location data to an emergency call center. The UE may provide cellular signaling to initiate an outgoing telephone call to an emergency call center. A token may be provided during the signaling, wherein the token is associated with location information of the UE device stored on a server computer (referred to as a cloud server or location server). The token may uniquely identify the UE device and/or a user cloud service account of the UE device. The call center may use the token to retrieve location information of the UE from the cloud server. The use of the token may also provide for enhanced security, e.g., to prevent spoofing of the UE phone number.
