Assignee: PARALLEL WIRELESS, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A virtualizing and interworking gateway, comprising:
a virtual 4G core providing for 4G networks a plurality of virtualized 4G network functions;
a virtual 5G core providing for 5G networks a plurality of virtualized 5G network functions;
an interface to a core network;
an interface to a 4G Radio Access Network (RAN);
an interface to a 5G RAN; and
an Interworking Function (IWF), the IWF including a shared IWF data store for 4G and 5G signaling,
wherein the IWF interworks signaling between the 5G RAN and the core network by causing the shared IWF data store to emit data based on data received from the 5G RAN and interworked to 4G RAN parameters;
wherein inter-RAT handovers use the virtual 5G core to send information to a 4G evolved packet core (EPC); and
wherein the virtualizing and interworking gateway provides interworking 4G to 5G such that the 5G RAN works with the 4G core.
