Problems solved by technology

[0009] The main purpose of the present invention is to solve the problem that the controller cannot actively send a message request to the service gateway and the packet data gateway, so that the controller, as a client, cannot update information through the service gateway and the packet data gateway when performing an active operation or a passive trigger operation. Technical issues preventing the message from being delivered properly

Embodiment Construction

[0044] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] The invention provides a communication interface, referring to figure 1 , figure 1 It is a structural schematic diagram of the application of the communication interface of the present invention in the EPS network architecture. Such as figure 1 As shown, the EPS network architecture includes a controller (Controller), a serving gateway (SGW-C), a packet data gateway (PGW-C), a mobility management entity (MME), a base station (eNB), a terminal (UE) and several serving The switch (SGW-U) and the external network switch (PGW-U) of the terminal, wherein the terminal is connected to the Internet through the base station, the switch, and the external network switch to establish a data transmission channel.

[0046] Wherein, the communication interface of the present invention is set between the controller, the ser...

Abstract

The invention discloses a communication interface. The communication interface is arranged between a controller and a service gateway and a packet data gateway. The communication interface uses the controller as a client side, and uses the service gateway and the packet data gateway as a server side, and is used for communication between the controller and the service gateway and the packet data gateway. The invention also discloses an information transfer method and system based on the communication interface. The information transfer method and system based on the communication interface realizes sending of information that is operated (modified or created) to the service gateway and the packet data gateway when the controller modifies or creates a message as a client side in an SDN-EPS network scene, so as to realize updating of the message to each part of a network, thereby ensuring normal transmission of data.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication interface and an information transmission method and system based on the communication interface. Background technique [0002] Software Defined Network (SDN) technology can use software programming on the control plane to implement various complex network applications, such as using SDN to implement EPS / GPRS networks. Wherein, the EPS (Evolved Packet System, Evolved Packet System) network is a fourth generation mobile communication network defined by 3GPP (3rd Generation Partnership Project, third generation partnership project). [0003] In the prior art, SDN is used to implement the architecture of EPS network (also called SDN-EPS or SDN-based EPS), UE is the communication terminal, and EUTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network) is the wireless access network. The network is internally ...
