Title: RADIO COMMUNICATION NETWORK, MOBILITY MANAGEMENT ENTITY, LOCAL GATEWAY, AND CONTROL PLANE NODE
Abstract:
A radio communication network includes: a control plane (C-plane) node (24) located in a core network (20); and a local gateway (14) located in a radio access network (RAN) (10) including a base station (11). The C-plane node (24) comprises a C-plane of a PDN gateway and provides a first C-plane interface with a PCC entity related to a policy-and-charging control (PCC). The local gateway (14) comprises a user plane of the PDN gateway and provides IP connectivity to the base station (11) so as to offload a particular type of traffic. Further, the local gateway (14) provides a second control plane interface with the C-plane node (24).
