Abstract

The invention provides a network controller and a network control method, which relate to the field of mobile communication networks. Wherein, the network controller of the present invention includes: a signaling processing module, used to receive and analyze signaling sent by other network elements, generate a signaling message and send it to the network element; an authentication module, used to complete the communication with the terminal Authentication and authentication; context management module, used to store and maintain and update various user context information; IP address allocation module, used to allocate IP addresses for terminals; policy control module, used to formulate policies; path and flow table management, used to Determine the business flow path and generate flow table information. Through such a network controller, the network control function of the core network is centralized, the separation of mobile network control and forwarding is realized, independent deployment, configuration, and upgrade are realized, signaling interaction between different devices is reduced, and the carrying capacity of the core network is increased. In this way, the core network can meet the demands of service volume development.

Description

Technical field [0001] The invention relates to the field of mobile communication networks, in particular to a network controller and a network control method. Background technique [0002] With the rapid development of the mobile Internet, services and user requirements will become more complex and diverse, and the corresponding network equipment functions will continue to be refined and enhanced for different services and user requirements. [0003] The existing core network control plane is interconnected by devices with various functions from various manufacturers. The existing core network structure, on the one hand, with the increasing complexity of equipment functions, network equipment is becoming more and more expensive, network deployment, operation and maintenance costs, energy consumption, etc. continue to increase; on the other hand, in order to meet new business and network innovation The rapid deployment of the network, once or several version updates a year will no...
