Abstract
Methods, computer-readable medium and a system are described for handling data traffic during Dedicated Bearer creation at a Packet Gate Way (PGW). In one embodiment, a method includes receiving, at a PGW user plane from a PGW control plane, a PFCP session modify request; creating a PDR-id (P1); sending, from the user plane to the control plane, a PFCP session modify response; receiving, at the control plane, downlink data matching PDR(P1); and performing at least one of allowing data since FAR(Fx) has a forwarding parameter, and sending data to peer node as per FAR (F1) forwarding parameters.

A method for handling data traffic during Dedicated Bearer creation at a Packet Gate Way (PGW), comprising:
- receiving, at a PGW user plane from a PGW control plane, a Packet Forwarding Control Protocol (PFCP) session modify request for an existing PFCP session;
- selecting, at the PGW control plane, a Forwarding Action Rules Identifier (FAR ID) corresponding to or based on an existing Packet Detection Rule (PDR) through which data traffic matching the service data flow (SDF) filters of a new the PDR (P1) identified as (P1) was passing through before creating the PDR (P1) for the existing PFCP session;
- creating the Packet Detection Rule (PDR) identified as (P1), wherein the PDR (P1) includes the selected FAR ID defining the Forwarding Action Rules (FAR) to be applied on traffic matching the PDR (P1);
- sending, from the PGW user plane to the control plane, a PFCP session modify response;
- handling data traffic at the PGW using the selected FAR ID during Dedicated Bearer creation, wherein handling data traffic at the PGW using the selected FAR ID during Dedicated Bearer creation includes handling data traffic at the PGW using the selected FAR ID until a CREATE_BEARER_RESPONSE message is received at the PGW control plane:
- updating the FAR with new forwarding parameters once the CREATE_BEARER_RESPONSE message is received at the PGW control plane;
- and
- sending new data traffic to a peer node based on the new forwarding parameters.
A non-transitory computer-readable medium containing instructions for handling data traffic during Dedicated Bearer creation at a Packet Gate Way (PGW) which, when executed, cause the PGW to perform steps comprising:
- receiving, at a PGW user plane from a PGW control plane, a Packet Forwarding Control Protocol (PFCP) session modify request;
- selecting, at the PGW control plane, a Forwarding Action Rules Identifier (FAR ID) corresponding to or based on an existing Packet Detection Rule (PDR) through which data traffic matching the service data flow (SDF) filters of a new the PDR (P1) identified as (P1) was passing through before creating the PDR (P1) for the existing PFCP session;
- creating the Packet Detection Rule (PDR) identified as (P1), wherein the PDR (P1) includes the selected FAR ID defining the Forwarding Action Rules (FAR) to be applied on traffic matching the PDR (P1);
- sending, from the PGW user plane to the control plane, a PFCP session modify response;
- handling data traffic at the PGW using the selected FAR ID during Dedicated Bearer creation, wherein handling data traffic at the PGW using the selected FAR ID during Dedicated Bearer creation includes handling data traffic at the PGW using the selected FAR ID until a CREATE_BEARER_RESPONSE message is received at the PGW control plane;
- updating the FAR with new forwarding parameters once the CREATE_BEARER_RESPONSE message is received at the PGW control plane;
- and
- sending new data traffic to a peer node based on the new forwarding parameters.
A Packet Gate Way (PGW) for handling data traffic during Dedicated Bearer creation, comprising:
- a processor;
- a memory in communication with the processor;
- a user plane executed on the processor using the memory;
- and
- a control plane executed on the processor using the memory in communication with the user plane,
- wherein the user plane is configured to receive, from the control plane, a Packet Forwarding Control Protocol (PFCP) session modify request for an existing PFCP session;
- wherein the control plane is configured to select a Forwarding Action Rules Identifier (FAR ID) corresponding to or based on an existing Packet Detection Rule (PDR) through which data traffic matching the service data flow (SDF) filters of a new the PDR (P1) identified as (P1) was passing through before creating the PDR (P1) for the existing PFCP session;
- wherein the user plane is further configured to create the Packet Detection Rule (PDR) identified as (P1), wherein the PDR (P1) includes the selected FAR ID defining the Forwarding Action Rules (FAR) to be applied on traffic matching the PDR (P1);
- wherein the user plane is further configured to send to the control plane, a PFCP session modify response;
- wherein the PGW is configured to handle data traffic using the selected FAR ID during Dedicated Bearer creation;
- wherein the PGW is further configured to handle data traffic using the selected FAR ID until a CREATE_BEARER_RESPONSE message is received at the PGW control plane;
- wherein the PGW is further configured to update the FAR with new forwarding parameters once the CREATE_BEARER_RESPONSE message is received at the PGW control plane;
- and
- wherein the PGW is further configured to send new data traffic to a peer node based on the new forwarding parameters.
