Abstract
A method, system and computer readable medium for providing support for CUPS PFCP Session at UE Level for Serving Gateway are presented. In one embodiment, a method includes providing a Packet Forwarding Control Protocol (PFCP) session at a User Equipment (UE) level for a Serving Gateway (SGW); anchoring, by the SGW, the UE session; handling, by the SGW, buffering of Idle UE and UE Active-to-Idle transitions; using, by the SGW, a same PFCP session for all Packet Data Networks (PDNs); and using, by the SGW, a same Buffering Action Rule (BAR) for all PDNs.

A method comprising:
- providing a Packet Forwarding Control Protocol (PFCP) session at a User Equipment (UE) level, wherein the UE level is different from a Packet Data Network (PDN) level, for a Serving Gateway (SGW);
- anchoring, by the SGW, the UE session at a session manager at the SGW, the session manager instantiating a data structure including information about the UE and about UE sessions for the UE with multiple PDNs;
- handling, by the SGW, buffering of Idle UE and UE Active-to-Idle transitions for the UE sessions;
- using, by the SGW, a single PFCP session for the UE sessions across the multiple PDNs;
- and
- using, by the SGW, a same Buffering Action Rule (BAR) for all PDNs associated with the UE sessions.
A system comprising:
- a Serving Gateway (SGW), having a Packet Forwarding Control Protocol (PFCP) session at a User Equipment (UE) level, wherein the UE level is different from a Packet Data Network (PDN) level, wherein the SGW anchors the UE session and handles buffering of Idle UE and UE Active-to-Idle transitions;
- wherein a same PFCP session is used for multiple Packet Data networks (PDNs);
- and
- wherein a same Buffering Action Rule (BAR) is used for multiple PDNs for a single UE session;
- providing a Packet Forwarding Control Protocol (PFCP) session at a User Equipment (UE) level for a Serving Gateway (SGW) at a session manager at the SGW, the session manager instantiating a data structure including information about the UE and about a plurality of UE sessions for the UE across multiple PDNs;
- anchoring, by the SGW, the plurality of UE sessions at the session manager;
- handling, by the SGW, buffering of Idle UE and UE Active-to-Idle transitions at the session manager;
- using, by the SGW, a same PFCP session for for the UE across the multiple PDNs;
- and
- using, by the SGW, a same Buffering Action Rule (BAR) for for the UE across the multiple PDNs.
A non-transitory containing instructions for providing support for Control Plane and User Plane Separation (CUPS) Packet Forwarding Control Protocol (PFCP) Session at UE Level for Serving Gateway which, when executed, cause a serving gateway to perform steps comprising:
- providing a Packet Forwarding Control Protocol (PFCP) session at a User Equipment (UE) level for a Serving Gateway (SGW), wherein the UE level is different from a Packet Data Network (PDN) level;
- anchoring, by the SGW, the UE session at a session manager at the SGW, the session manager instantiating a data structure including information about the UE and about UE sessions for the UE with multiple PDNs;
- handling, by the SGW, buffering of Idle UE and UE Active-to-Idle transitions for the UE sessions;
- using, by the SGW, a single PFCP session for the UE sessions across the multiple PDNs;
- and
- using, by the SGW, a same Buffering Action Rule (BAR) for all PDNs associated with the UE sessions.
