Abstract
Systems, methods, and devices that relate to prompt restoration of Internet Protocol (IP) Multimedia Subsystem (IMS) services when a Serving Call Session Control Function (S-CSCF) becomes unavailable are disclosed. In one example aspect, a method for wireless communication includes receiving, by a first network node in a network, a user profile associated with a user device from a home server configured to manage subscriber information. The user profile comprises binding information about a Proxy Call Session Control Function (P-CSCF) that is in communication with the user device. The method also includes retrieving, by a second network node, the binding information of the P-CSCF upon a third network node being unreachable for completing a call for the user device to enable a completion of the call for the user device.
