Abstract: In accordance with various embodiments, a method is performed including establishing a first communication session between an application function and a user equipment assigned a first IP address. The method includes determining, by the application function, that the user equipment has changed location. The method includes, in response to determining that the user equipment has changed location, sending, by the application function, a request that the user equipment be assigned a second IP address. The method includes establishing a second communication session between the application function and the user equipment assigned the second IP address.

Abstract: Systems, methods, and computer-readable media for managing service calls over a network may include a signal routing engine with a maintained forwarding table for various network functions and micro-services in a services back end for the network. The signal routing engine can include a call conversion service for converting REST API calls to an internal network call protocol for increasing network function processing speeds, decreasing bandwidth usage, and improving network responsiveness and manageability.
