Embodiment 1

[0038] The PFCP session processing device of the present invention realizes the N4 interface of the control plane, receives the PFCP messages sent by the SMF and the UPF, and then processes and forwards the received messages. The session processing device such as image 3As shown, it includes a receiving module, a processing module and a forwarding module; the receiving module is responsible for receiving the PFCP session request message sent by the SMF, and receiving the PFCP session response message returned by the uplink UPF and / or downlink UPF; the processing module is responsible for performing the PFCP session request message Separation, and responsible for integrating the PFCP session response message; the forwarding module is responsible for sending the separated PFCP session request message to the corresponding uplink UPF and / or downlink UPF, and responsible for forwarding the integrated PFCP session response message to the corresponding SMF.

Embodiment 2

[0042] PFCP session processing method of the present invention, such as Figure 4 shown, including the following steps:

[0043] Step S1, the receiving module of the PFCP session processing device receives the PFCP session request message sent by the SMF;

[0044] Step S2, the processing module of the PFCP session processing device analyzes the PFCP session request message, separates the PFCP session request message according to the request processing strategy, and constructs a new PFCP session request message;

[0045] The PFCP session request message contains many rules for processing uplink and downlink data, such as PDR (PacketDetection Rule), FAR (Forwarding Action Rule), URR (UsageReporting Rule), BAR (Buffering Action Rule buffer operation rules), QER (Qosenforcement Rule Qos implementation rules) and so on. In addition to its own identifier (PDR ID), the PDR field also includes identifiers of other rules, such as BAR ID, FAR ID, etc., and is associated with other rul...

Abstract

The invention provides a PFCP session processing method and device, and the device comprises: a receiving module which is responsible for receiving a PFCP session request message sent by an SMF, and receiving a PFCP session response message returned by an uplink UPF and/or a downlink UPF; a processing module which is responsible for separating the PFCP session request message and constructing a new PFCP session request message, and is responsible for integrating PFCP session response messages; and a forwarding module which is responsible for respectively sending the separated PFCP session request message to the corresponding uplink UPF and/or downlink UPF, and forwarding the integrated PFCP session response message to the corresponding SMF. According to the method, the uplink data and thedownlink data of the data plane are separated, the uplink or downlink data plane sinks to the edge network independently, the flexibility and diversity of network deployment are improved, and the dataprocessing capacity of the UPF is improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for processing a PFCP session. Background technique [0002] In the 5G mobile network, the user terminal UE sends a PDU session establishment request to the access and mobility management function AMF. After receiving the request, the AMF sends a PDU session SM context creation request to the session management function SMF, and the SMF interacts with the control plane network element UDM. , the SM context is successfully created. The SMF sends a PFCP session establishment request to the user plane function UPF, and the UPF returns a SMFPFCP session establishment response. The SMF transmits the IP address of the UPF to the access network (R)AN through the N2 message transparent transmission service of the AMF, and the (R)AN sends the uplink data to the UPF according to the IP address of the UPF; The relevant information is passed to the SMF, and the S...
