    Abstract: System and method embodiments are provided for evolved packet core cluster and session handling. In an embodiment, a method in a network component for cluster and session handling includes receiving, by a MC-C in a first resource pool in a cluster of resources, an attach request from a SORC for a PDN connection for a UE, the MC-C and the first resource pool selected by the SORC according to a UE address, a resource load, and an operator policy; configuring session control and gateway resources for a session for the UE; negotiating with a follower site to determine state information for a bearer context of the UE; synchronizing the state information with follower sites when a state is agreed upon by at least some of the follower sites; and forming an availability group according to a set of servers that hold replicated state information for the UE.

    Abstract: According to one aspect of the present disclosure, there is provided a method, by a virtual network function, that includes: receiving a first request from a user equipment (UE), the first request including first parameters and a first token, the first token being a vector value corresponding to a session state for the UE; determining the session state for the UE according to the first token; programming network resources according to the session state, the programming updating states of the network resources, wherein the session state for the UE is updated when the states of the network resources are updated; producing a second token corresponding to the updated session state for the UE; storing the updated session state and the second token; and transmitting the second token to the UE.

    Abstract: An embodiment method for session handling for a connection between an UE and a network includes establishing, at a first distributed EPC, user and IP sessions over the connection through the first distributed EPC. The first distributed EPC includes a first PGW at which the IP session is anchored. The method also includes holding original IP resources and releasing original connection resources for the sessions at the first distributed EPC when the UE moves beyond the first distributed EPC to a second distributed EPC. The method then establishes a tunnel between the first PGW and a second PGW for the second distributed EPC. The tunnel utilizes the original IP resources and new connection resources at the second distributed EPC. The method then routes data from the tunnel, through the first PGW, and to the network.
