Embodiment 1

[0094] see Figure 7 , the figure shows a user plane data processing method, the specific steps are as follows:

[0095] Step 701, the access device determines the information used to identify the uplink / downlink PDU flow and the associated information of the uplink / downlink PDU flow;

[0096] It should be noted that the foregoing access device may be an NG-RB, but of course it is not limited thereto.

[0097] The above-mentioned uplink / downlink PDU flow refers to an uplink PDU flow or a downlink PDU flow, and " / " in this embodiment means "or".

[0098] Optionally, the access device can obtain the information used to identify the uplink / downlink PDU flow and the associated information of the uplink / downlink PDU flow in a manner stipulated in the protocol or in a manner notified by the network, for example, the access device obtains the identification information from the core network. Of course, the information about the uplink / downlink PDU flow and the associated informatio...

Embodiment 2

[0126] see Figure 9 , the figure shows a user plane data processing method, the specific steps are as follows:

[0127] Step 901, the access device determines the association information between the uplink / downlink PDU flow filter template and the PDU flow;

[0128] The above upstream / downstream PDU flow filter template can also be called upstream / downstream PDU flow filter (upstream / downstream PDU flow filter)

[0129] Step 902, the access device receives the uplink / downlink data packet, and determines the PDU session to which the received uplink / downlink data packet belongs;

[0130] For example, the PDU session to which the data packet belongs is determined according to the relevant information carried in the header of the uplink / downlink data packet.

[0131] Step 903, the access device determines the uplink / downlink PDU flow filtering template corresponding to the uplink / downlink PDU flow in the PDU session according to the association information between the uplink / do...

Embodiment 3

[0155] see Figure 14 , the figure shows a user plane data processing method, the specific steps are as follows:

[0156] Step 1401, the access device determines the association information between the uplink / downlink PDU flow identifier and the PDU flow;

[0157] It should be noted that the foregoing access device may be an NG-RB, but of course it is not limited thereto.

[0158] Step 1402, the access device receives the uplink / downlink data packet, and determines the PDU session to which the received uplink / downlink data packet belongs;

[0159] Step 1403, the access device determines the uplink / downlink PDU flow identifier corresponding to the uplink / downlink PDU flow in the PDU session according to the association information between the uplink / downlink PDU flow identifier and the PDU flow;

[0160] In this embodiment, the access device can acquire the association information between the uplink / downlink PDU flow identifier and the PDU flow through protocol agreement or n...

Abstract

The embodiment of the invention provides a user plane data processing method and device. Through differentiation of uplink / downlink PDU flows, a one-to-one mapping relation between the uplink / downlinkPDU flows and radio bearers is changed, so the signaling process complexity is effectively reduced, and the flexible routing is supported. The processing method comprises the steps that an access device determines information for identifying the uplink / downlink PDU flows and correlation information of the uplink / downlink PDU flows; and the access device identifies the uplink / downlink PDU flows ina PDU session according to the information for identifying the uplink / downlink PDU flows and the correlation information of the uplink / downlink PDU flows, thereby differentiating different uplink / downlink PDU flows.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for processing user plane data. Background technique [0002] see figure 1 , the figure shows the bearer model in the existing LTE (Long Term Evolution, Long Term Evolution) system, the bearer in the existing LTE involves multi-layer mapping, from the EPS Bearer (EPS bearer) and the access network ERAB (Evolved Radio Access One-to-one mapping between Bearer (evolved radio access bearer), and one-to-one mapping between the access network ERAB and the air interface RadioBearer (radio bearer), however, this mapping mechanism between multi-layer bearers brings complex signaling interaction process. [0003] In order to avoid the problems of low flexibility of QoS (Quality of Service, quality of service) architecture and complex signaling interaction in the LTE network. In the future 5G communication system, a new and more flexible QoS framework...
