Description

Data distribution method

Technical Field

The invention relates to the field of edge calculation, and particularly provides a data distribution method.

Background

Currently, in order to realize ultra-low time delay of 5G data, a UPF and an edge computing platform are deployed nearby for a base station in need. Each base station can be connected with a dedicated edge computing platform node in a butt joint mode, and a low-delay network of a segment is formed by combining UPF equipment. And the UPF distributes the specific data to the edge computing platform corresponding to the base station according to the strategy.

The method has the following disadvantages:

handover occurs when a terminal moves within a sector formed by such multiple base stations. The edge computing node where the terminal accesses the same application after switching also needs to send the switching. This makes scheduling of UPF data to different edge computing platforms, and scheduling of processing for the same application on multiple edge computing platforms, cumbersome if multiple handovers need to occur if the terminal reaches the final destination from the source switch occurrence.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a data distribution method with strong practicability.

The technical scheme adopted by the invention for solving the technical problems is as follows:

a data distribution method comprises the following steps:

s1, switching process between base stations;

s2, recording the switching of the terminal to form a track;

s3, sending the analysis result of the terminal travel track to a UPF through the SMF;

s4, comparing the travel track with the edge computing node scheduling relation by a UPF;

s5, selecting a N6 port routing edge according to the path to calculate a node target;

s6, switching the data of the N3 to UPF;

s7, UPF sends N6 data to the switching terminal edge computing node.

Further, a white list of terminals in the park is configured in the UPF, and mapping tables of different base stations corresponding to different edge computing platform nodes are configured.

Furthermore, an user behavior analysis function is started in the UPF, and the travel track of the white list terminal is recorded and analyzed;

when the terminal has a fixed stroke track, the switching stroke of the base station is consistent with the switching stroke of the terminal.

Further, for the terminal, when the UPF performs the edge computing node switching, the data is directly distributed to the destination node.

Further, in step S3, the core network AMF records the travel route of the terminal in the jurisdiction area, and notifies the UPF of the terminal SUPI having the fixed handover route, and the terminal access start point and the terminal destination end point information via the SMF.

Further, in step S4, the UPF records the trip switching path information and corresponds to the shunting destination edge computing node.

Further, in step S7, when the SUIP terminal initiates the handover procedure from the access start point again, the UPF directly shunts the N6 data to the edge computing node corresponding to the end point.

Preferably, the AMF is to store and analyze handover start point and end point information of all terminals.

Further, the DPF counts the information of edge calculation nodes corresponding to each switching destination base station of the stroke to obtain the starting and ending point relation of the edge calculation nodes of the terminal track;

when the trace occurs again, terminal N6 data is dispatched directly to the endpoint edge compute node.

Compared with the prior art, the data distribution method has the following outstanding beneficial effects:

the invention reduces the multiple routing forwarding process of the UPF shunt data to different edge computing nodes when the terminal is switched, and reduces the frequent starting and stopping of the service of the different edge computing nodes aiming at the terminal.
