SYSTEMS AND METHODS FOR EVOLVED PACKET CORE CLUSTER AND SESSION HANDLING

摘要

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.
