Abstract
Techniques for determining a location of a roaming device on a host telecommunications network are described herein. The host telecommunications network can implement a location server to determine a geographical location of a user equipment (UE) that generates an emergency message to an emergency service center. The location server can exchange data representing device information, network information, or user information with a subscriber server of a home telecommunications network, and use the data to initiate determination of the geographical location. The location server can initiate, establish, maintain, or otherwise determine a geographical location of the UE for sending to the emergency service center (e.g., to enable the UE to exchange text communications with a Public Service Answering Point).
