Abstract

The invention discloses a method used for realizing control and forwarding function decoupling, an apparatus and a system thereof. Control surface equipment establishes a user context when receiving an establishment session request sent by a base station and sends first flow table expansion information to forwarding surface equipment. The first flow table expansion information comprises a tunnel identification and first motion indication information so that the forwarding surface equipment carries out expansion on a local OpenFlow flow table. The forwarding surface equipment sends second flow table expansion information when receiving downlink data. The control surface equipment carries out expansion on the local OpenFlow flow table when receiving the second flow table expansion information and sends an establishment session response to a base station so as to establish wireless bearing associated with the tunnel identification between user terminal and a mobile management entity. Through expanding the OpenFlow flow tables of a control surface and a forwarding surface, control forwarding function decoupling of a mobile network architecture can be effectively supported and flexibility and high effectiveness of network management and operation are realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for decoupling control and forwarding functions. Background technique [0002] With the rapid development of mobile networks in recent years, the penetration rate of mobile users has been increasing steadily every year, which provides operators with more business opportunities and also brings more challenges. The continuous improvement of mobile communication technology has improved the quality of network service and attracted more users to join. At the same time, with the emergence of a wide variety of mobile services and applications, the increasing variety of mobile Internet applications has further enhanced the interest of users, and the services on the traditional fixed network have gradually migrated to the mobile network, which has intensified the data traffic of the mobile network. rapid growth. The crazy growth of mobile data traffic has ag...
