Embodiment Construction
[0049] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.
[0050] figure 1 A flowchart showing a cellular network control method according to an embodiment of the present invention. Such as figure 1 As shown, the method mainly includes:
[0051] Step S100, the network element receives the OpenFlow message sent by the centralized controller, and the OpenFlow message includes an OpenFlow control instruction;
[0052] Step S102, analyzing the OpenFlow message to obtain the OpenFlow control instruction;
[0053] Step S104, execute the OpenFlow control command according to the preset rules.
[0054] In this way, by extending the existing OpenFlow protocol and using OpenFlow messages to send OpenFlow control commands, the wireless network control and data forwarding functions all use the OpenFlow protocol uniformly without using two sets of protocols, thereb...

The invention discloses a cellular network system, a cellular network control method, a cellular network control device, a network element and a centralized controller. The method comprises steps that an OpenFlow message sent by the centralized controller is collected by the network element, and the OpenFlow message comprises an OpenFlow control instruction; the OpenFlow message is analyzed to acquire the OpenFlow control instruction; the OpenFlow control instruction is performed according to preset rules. According to the cellular network system, the cellular network control method, the cellular network control device, the network element and the centralized controller, the control instruction is sent through the OpenFlow message, so wireless network control and data forwarding functions employ an OpenFlow protocol in a unified mode, two sets of protocols are not needed, and thereby an interface protocol at a control face and a data face is simplified.
Description
technical field [0001] The present invention relates to the communication field, in particular to a cellular network system, a control method, a device, a network element and a centralized controller. Background technique [0002] For the future 5G (5-Generation, fifth-generation) network, people put forward more "strict" requirements in terms of speed, capacity, delay, and the integration of various network standards. In order to realize these requirements, various enterprises and standards organizations are focusing on researching key technologies such as high-frequency band transmission, large-scale antenna, full-duplex, new network architecture and ultra-dense networking. Due to the complex network standards in the future, which will include 2G to 5G networks, WIFI (Wireless-Fidelity, Wireless Fidelity) and other network technologies, in order to achieve multi-network integration and flexible scheduling and coordination of resources and interference between different sta...
