Abstract
A communication network configured to substitute serving gateway (“SGW”), packet data network gateway (“PGW”), and mobility management entity (“MME”) with an OpenFlow network controller (“OFNC”) for packets routing between mobile devices and the Internet is disclosed. The network includes a cellular base station, a packet data network (“PDN”), and OFNC. The cellular base station provides wireless communication for user equipments (“UEs”). The PDN is able to route packet flows to their destination(s). The routing controller or OFNC manages a cluster of routers including at least one edge router via OpenFlow protocol. The OFNC, in one embodiment, establishes a routing path between the cellular base station and the PDN for an authenticated UE via a group of routers based on information obtained from an authenticating server and a charging system.
