发明名称 Method and apparatus for providing E911 services via network announcements
摘要 A method and apparatus for providing emergency services, e.g., E911 services, for nomadic users by utilizing network announcements to remind customers to update location information used to provide services on packet networks, such as Voice over Internet Protocol (VoIP) and Service over Internet Protocol (SoIP) networks, are disclosed. For example, the method enables the VoIP or SoIP service provider to detect a change in the IP address associated with either the broadband modem or the router through which a terminal adaptor is used to access services when a customer is logging on from a new location. In turn, the method sends a reminder network announcement message to the terminal adaptor, e.g., to be played when the terminal adaptor goes off-hook.
