Abstract
A method of operating a policy and charging rules function ('PCRF') node to handle an internet protocol multimedia subsystem ('IMS') emergency call can include receiving an identity request from a proxy call session control function (“P-CSCF”) of an IMS network. The identity request can include an internet protocol (“IP”) address for a user equipment (“UE”). The method can further include, responsive to receiving the identity request, determining one or more identifiers of the UE based on the IP address. The one or more identifiers are separate from the IP address. The method can further include, responsive to determining the one or more identifiers, transmitting an indication of the one or more identifiers of the UE to the P-CSCF.
