Abstract:
1. A method comprising: receiving information identifying a terminal device at a token generator within a communication network; generating a plurality of tokens by the token generator based on the information, wherein the tokens are used by the terminal device when placing emergency calls and each token contains sufficient validation information to uniquely identify the terminal device in the communication network, the plurality of tokens limiting a number of false emergency response service requests allowed for the terminal device; sending the generated tokens to the terminal device; receiving a token from the terminal device with a request from the terminal device to establish the emergency call; validating the emergency call originating from the terminal device using a token validator within the communication network; establishing the emergency call upon validation of the token and identification of the terminal device; generating a replacement token when the emergency call is not a false emergency response service request; and sending the replacement token to the terminal device for use for another emergency call.
