Using location identifier separation protocol to implement a distributed gateway architecture for 3GPP mobility

Abstract:

A method implemented by a network device in a cellular communication network with a distributed data plane serving gateway (S-GWu) at an evolved universal terrestrial radio access network (E-UTRAN) node B (eNodeB). The method enables an ingress tunnel router to forward traffic between devices connected to the cellular communication network via location identifier separation protocol (LISP) to enable mobility within the cellular communication network without anchor points.
