Method for lightening core network in resource limited scene

Abstract

The embodiment of the invention relates to the technical field of communication, in particular to a method for a lightweight core network in a resource limited scene. The method comprises the following steps: constructing the lightweight core network, communicating and registering a new terminal through an access signaling of the core network, and performing data synchronization by the terminal added into the core network according to a data synchronization model of the core network. i.e., enabling user equipment to send data to a lightweight core network MCN in a local region and requests feedback; if a target resource exists in a local MCN cache, directly sending the content back to a terminal, and updating the local MCN cache; if the target resource does not exist in the local MCN cache, requesting for the target resource from a ground control center GCN or an MCN which caches the target resource at a far end, and sending the resource to the local MCN. According to the invention, by designing a lightweight core network data synchronization process, dynamic synchronization of data information of the whole network is ensured, fusion on a data business service level is realized, and the reliability of network communication is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a method for a lightweight core network in a resource-constrained scenario. Background technique [0002] Mobile communication networks, unmanned aerial vehicle ad hoc networks and satellite networks play a very important role in my country's communication field, and these networks are all resource-constrained networks. They provide users with more flexible access services through mobile networking. However, due to the characteristics of rapid dynamic changes between communication nodes and limited node resources, there will be constant relative movement between the base station and the terminal. In order to ensure the continuity of communication, the terminal needs to continuously switch between the base stations to obtain Continuous and reliable communication services, so that a large amount of interactive information will be generated freque...

Problems solved by technology

If the above solution is adopted, it will not be able to support the network management and control capabilities of edge dynamic nodes, and this solution is very easy to be bound by the current public core network equipment manufacturers, and cannot guarantee the security and independence of the network
