Embodiment Construction

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0032] Such as figure 1 As shown, a 5G mobile communication method based on MEC and layered SDN, including:

[0033] S101. The local wireless access network receives the service request sent by the user through the terminal, and forwards it to the MEC edge node;

[0034] S102. After receiving the service request, the MEC edge node sends a Packet-in message to the MEC node controller included in the SDN sub-controller through the switch of the MEC edge node;

[0035] S103. After receiving the Packet-in message, the MEC node controller judges whether there is a service or business consistent with the service request in the MEC edge node, and if not, forwards the service request to the general controller;

[0036] S1...

Abstract

The present invention discloses a 5G mobile communication method and system based on MEC (Mobile Edge Computing) and a hierarchical SDN (software defined network). The method includes the following steps that: S1, a business request is received and is forwarded to an MEC edge node; S2, a Packet-in message is sent to an MEC node controller through the switch of the MEC edge node; S3, whether the MEC edge node has business consistent with business requested by the business request is judged; S4, a total controller performs network slicing planning and selection according to the business request, and then sends a Packet-out message to a core network controller included in an SDN sub-controller; S5, the core network controller performs resource scheduling processing on a mobile network, and buffers business or services related to the business request to the MEC edge node according to current resource occupation quantity; and S6, a terminal acquires the business or services from the MEC edge node. With the 5G mobile communication method and system provided by the technical schemes of the invention adopted, problems such as delay, congestion and capacity of a network can be solved, and ultimate experience of terminal users can be realized. The method and system have the advantages of high traffic, low time delay, low energy consumption, high reliability and the like.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a 5G mobile communication method and system based on MEC and layered SDN. Background technique [0002] Due to the explosive growth of data traffic and the connection with massive devices, the existing mobile communication architecture will cause problems such as network delay, congestion and capacity, which will lead to long cloud computing delays, low network data processing efficiency, high energy consumption and issues such as low reliability. Contents of the invention [0003] The present invention provides a 5G mobile communication method and system based on MEC and layered SDN to solve the problems in the prior art. [0004] The technical solution of the present invention to solve the above technical problems is as follows: a 5G mobile communication method based on MEC and layered SDN, comprising: [0005] S1. The local wireless access network receives the s...
