Apparatus, system and method for controlling access

Abstract

Embodiments of the present invention provide a device, system and method for access control, and relate to the communication field. The device includes: a receiver, a processor and a transmitter. The method includes: receiving the first service chain forwarding rule sent by the controller; receiving the first message sent by the classifier; When the first service chain identifier matches, forward the first packet to the first access network element according to the first identifier. The present invention realizes the control of the access network element based on the SDN mechanism, and the control plane can realize the forwarding control of the access network and the service processing network based on a unified forwarding control mode, and realizes the SDN access network based on the service chain in the mobile network. Access management and mobility management.

Description

technical field [0001] The present invention relates to the communication field, in particular to a device, system and method for controlling access. Background technique [0002] In the current telecommunication network, a concept of a software-defined network (Software-Defined Network, SDN for short) is proposed. [0003] In SDN, the control logic and forwarding function of network elements are decoupled, and the control logic is deployed centrally. The controller (Controller) for realizing the control logic of the network element realizes the flexible control of the packet processing flow by controlling the processing rules stored in the forwarding switch (Switch). The forwarder matches the matching field of the message with the matching field in the processing rule, and if the match is successful, it performs various processing on the message according to the corresponding action set in the processing rule. [0004] In a mobile network, the SDN mechanism is mainly used...

Problems solved by technology

[0005] However, the above SDN mechanism does not involve the wireless access network including access network elements such as base stations. Moreover, the service chain identifier is used for routing in the Gi-LAN domain, and the tunnel identifier of user packets is used for routing in the wireless access network. Routing and forwarding mechanisms are not the same

Therefore, different networks adopt different forwarding mechanisms, which leads to complex implementation of control function logic, the forwarding mechanism between the Gi-LAN domain and the wireless access network cannot be unified, and the SDN-based mechanism in the mobile network cannot realize the control of access network elements
