Abstract: A method to operate a core network element, such as a Session Management Function (SMF) of a 5G core architecture. The method includes establishing a session between a user equipment and a core network element, determining, on the core network element, an activity pattern for the session, and based on the activity pattern, one of maintaining context information for the session in cache memory of the core network element and off-loading the context information for the session from the cache memory of the core network element to a database that is different from the cache memory.

Abstract: Method for reducing interface traffic and memory of a session management function (SMF) establishes an exchange of preservation between the SMF and a policy control function (PCF) via an interface for a first session by a first subscriber in a wireless network. The method also includes receiving, by the SMF from the PCF, the preservation including definitions of common data and a preserve indication for the definitions of the common data. The definitions of the common data are used for a plurality of sessions following the first session by a plurality of subscribers. The method also includes storing, by the SMF, the definitions of common data; establishing an exchange of preservation between the SMF and the PCF for one of the plurality of sessions by a second subscriber; and receiving, by the SMF, references to the common data without the definitions of the common data.
