Abstract
The authorized IP addresses configured at components in an IMS network may become out of sync with the authorized IP address provided by a core network to UEs. This may result in emergency communications being received at the IMS network from a UE using a core network-authorized address that is not recognized by the IMS network. An IMS component may be configured to map an unauthorized address from an emergency communications to an authorized address and route the communications within the IMS network using the authorized address. An IMS component may also, or instead, add an unauthorized address from an emergency communications to a listing of authorized addresses so that the communications can be routed normally. An IMS component may also, or instead, transmit an authorized address to the UE via a policy component for configuration at the UE so that subsequent emergency communications will be authorized.
