Abstract: A method and apparatus for managing access network information are provided. The method includes: the dynamic access network information is obtained, and the current access network information list can be updated in real time according to the obtained dynamic access network information, so as to ensure that access network information obtained by a user terminal from the access network information list is latest information updated in real time. Thus, after the user terminal obtains the information, a process of scanning an access network to determine current availability information of the network can be omitted, so that the switching delay can be reduced, the switching efficiency can be improved, and the power consumption of the user terminal can be reduced, thereby improving the satisfaction degree of user experience.

Abstract: A method for routing forwarding is provided. The method includes: a controller sends pre-generated routing flow tables to an Evolved Universal Terrestrial Radio Access Network (UTRAN) NodeB (eNB) and an Access Gateway (AGW) respectively; and the eNB and the AGW distribute data according to the received routing flow tables respectively. The controller sends the routing flow tables to the eNB and the AGW, so that the extended OpenFlow protocol can be applied to an Evolved Packet System (EPS), network upgrading cost is lowered, network upgrading can be simplified, and a network upgrading period can be shortened.

Abstract: A method and system for routing forwarding are described. The method includes: a controller sends pre-generated routing flow tables to an Evolved Universal Terrestrial Radio Access Network (UTRAN) NodeB (eNB) and an Access Gateway (AGW) respectively; and the eNB and the AGW distribute data according to the received routing flow tables respectively. A controller for routing forwarding is described. According to the disclosure, the controller sends the routing flow tables to the eNB and the AGW, so that the extended OpenFlow protocol can be applied to an Evolved Packet System (EPS), network upgrading cost is lowered, network upgrading can be simplified, and a network upgrading period can be shortened.

Abstract translation: 描述了用于路由转发的方法和系统。 该方法包括：控制器将预先生成的路由流表分别发送到演进通用陆地无线电接入网（UTRAN）NodeB（eNB）和接入网关（AGW）; eNB和AGW分别根据接收到的路由流表分发数据。 描述用于路由转发的控制器。 根据本发明，控制器向eNB和AGW发送路由流表，扩展的OpenFlow协议可以应用于演进分组系统（EPS），网络升级成本降低，网络升级可以简化， 可以缩短网络升级时间。
