Data distribution method and device in edge MEC

Abstract

The invention relates to the field of communication, in particular to a data distribution method and device in edge MEC. The method is used for solving the problem of centralized processing of data inedge MEC. Timely delivery of network services is ensured. The method comprises the following steps: after a preset distributing rule is read by an edge UPF, receiving a request message sent by an edge SMF, judging whether the request message is a request DNS service or not, if so, distributing a data packet from the edge SMF according to the DNS distributing rule, and otherwise, distributing thedata packet from the edge SMF according to a quintuple distributing rule. Thus, the edge UPF can perform distributing processing on different types of request messages, the data processing capabilityof the edge UPF is improved, the data transmission time delay is reduced, the network service efficiency is improved, and the user experience is further improved. In addition, the edge SMF can flexibly schedule the edge UPF, the network load is reduced, and the network resource utilization rate is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for distributing data in an edge MEC. Background technique [0002] With the rapid development of the mobile Internet, people's demand for mobile services has increased rapidly, and network resources have become increasingly scarce. How to improve user experience and reduce network resource consumption has become an important problem to be solved. [0003] As an evolution of cloud computing, Mobile Edge Computing (MEC) can download application hosting from the centralized data center to the edge of the network, and provide users with the nearest mobile service and the mobile service required by the wireless access network. Cloud computing capabilities. MEC has obvious advantages in reducing latency and improving bandwidth efficiency, and is considered to be one of the key performance indicators (KeyPerformance Indicator, KPI) that meets the requirements of t...

Problems solved by technology

[0006] In addition, according to the existing technology and the PDU session flow, in establishing a PDU session and selecting a UPF, the configuration rules of the UPF follow the capability exposure function (Network Exposure Function, NEF)-policy control function (Policy Control Function, PCF)-session management function SMF In some specific deployments, the local UPF is even a part of the MEC, and the SMF centrally processes the content required by the user, which increases the network burden and computing overhead, reduces the utilization of network resources, and furthermore, the user cannot timely Obtain desired mobile services, degraded user experience
