Abstract

A gateway situated between the RAN and the core network may provide 2G/3G/4G/Wi-Fi convergence for nodes in a network on a plurality of radio access technologies. In some embodiments, a convergence gateway is described that allows for legacy radio access network functions to be provided by all-IP core network nodes. A multi-RAT gateway provides 2G/3G Iuh to IuPS interworking, IuCS to VoLTE interworking via a VoLTE proxy, IuPS and 4G data local breakout or S1-U interworking, and 2G A/IP and Gb/IP to VoLTE and S1-U/local breakout interworking. The multi-RAT gateway may thereby support all voice calls via VoLTE, and all data over S1 or local breakout, including VoLTE. The multi-RAT gateway may provide self-organizing network (SON) capabilities for all RATs. A multi-RAT base station may provide 2G and 3G front-end interworking to Iuh.

Claims13

Dependent claims

A system for multi-radio access technology (multi-RAT) telecommunications networking, comprising:

a multi-RAT gateway, the multi-RAT gateway further comprising:
an inbound 5G interface for handling 5G inbound radio access network signaling data flows;
an inbound Iuh interface for handling inbound signaling, call, and user data flows on either or both of a 2G RAT or a 3G RAT;
an inbound IuCS interface for handling inbound call data flows on either or both of the 2G RAT or the 3G RAT, the inbound IuCS interface being coupled to the inbound Iuh interface;
an inbound IuPS interface for handling inbound user data flows on either or both of the 2G RAT or the 3G RAT, the inbound IuPS interface being coupled to the inbound Iuh interface;
an inbound S1-AP interface for handling 4G inbound signaling data flows;
an inbound S1-U interface for handling 4G inbound user data flows;
a Voice over LTE (VoLTE) interworking proxy for performing interworking from inbound call data flows, the VoLTE interworking proxy being coupled to the inbound IuCS interface;
and
an outbound data flow router for routing inbound user data flows on either, some, or all of 2G, 3G, or 4G 5G user data flows to either an outbound S1interface or an outbound local breakout IP interface,
wherein the VoLTE interworking proxy is further coupled to the outbound data flow router such that outbound VoLTE traffic flows destined for an Internet Protocol Multimedia Subsystem (IMS) core network are routed to either the outbound S1 interface or the outbound local breakout IP interface, and
wherein the inbound S1-AP interface and the inbound S1-U interface are further coupled to the outbound data flow router.
