A Novel Load Balancing Strategy for Network Functions in Telecommunication Networks

Effective load balancing will play a critical role for network function (NF) introduced in 5G telecommunication network, accompanied with the domestic 5G construction in full range and speed, in which network operation efficiency and service quality are compulsory indicators spectacularly. The network element based on service based architecture and interface is recognized as NF in cloud network, which is one of the main discrepancies between 5G core network and 4G core network. A series of load balancing solutions applied to NF is manifested, in scenarios of new suppliers and new nodes from existing suppliers, and tries to rebuild network architecture with new mechanism for carrying out control process automatically according to load balancing strategy. Finally, case study based on messaging flow of specific service is depicted for practice.
