Abstract
Systems and methods for registering and selecting a Proxy-Call Session Control Function (P-CSCF) are described herein. The systems and methods described herein use a Network Repository Function (NRF) to receive status updates of P-CSCFs available to be selected. The status updates include information such as, but not limited to, whether or not the P-CSCF is active or above or below a predetermined loading threshold. The NRF provides the information to a Session Management Function (SMF) that selects which P-CSCF is to be utilized for a Session Initiation Protocol. The SMF can also use loading levels of the P-CSCFs to perform load balancing.
