Abstract
The authorized IP addresses configured at components in an IMS network may become out of sync with a first pool of IP addresses provided by a core network to UEs. This may result in emergency communications being received at the IMS network from a UE using a first IP address of the first pool of IP addresses that is not recognized by the IMS network. A session management component of the core network may automatically assign a second IP address from a second pool of IP addresses based on determining the session management component has not received an update notification from the IMS network within a threshold time (e.g., 500 milliseconds, 1000 milliseconds, etc.) from transmitting a request to establish a packet data communications session to the IMS network using the first IP address. The IMS network may then receive packets from the second IP address.
