SIM Whitelisting and Multi-Operator Core Networks

A system, comprising:

• a first base station for receiving messages from a first user equipment (UE);
• a second base station for receiving messages from a second user equipment (UE);
• and
• a gateway coupled to at least one eNodeB and acting as a virtualizing gateway for communications from at least one eNodeB to one or more core networks, the one or more core networks including a serving gateway (SGW) and a packet data network gateway (PGW), the one or more core networks having at least two radio access technologies (RATs),
• wherein the virtualizing gateway further comprises:
• a processor;
• and
• a memory comprising instructions that, when executed by the processor, cause the processor to perform steps including:
• receiving, at the virtualizing gateway, a first service request from a first user equipment (UE) via the first base station;
• creating, at the virtualizing gateway, an association from each of a plurality of UE identifiers to a desired core network;
• applying, at the virtualizing gateway, a first filter using a first UE identifier of the first UE, based on the association;
• forwarding, at the virtualizing gateway, the first service request from the first UE to a first core network based on the applied first filter;
• receiving, at the virtualizing gateway, via the second base station, a second service request from a second user equipment (UE);
• applying, at the virtualizing gateway, a second filter using a second UE identifier of the second UE, based on the association;
• and
• forwarding, at the virtualizing gateway, the second service request from the second UE to the second core network based on the applied second filter.

A non-transitory computer-readable medium comprising instructions that, when executed by a processor at a virtualizing gateway, cause the virtualizing gateway to:

• receive a first service request from a first user equipment (UE) via a first base station;
• create an association from each of a plurality of UE identifiers to a desired core network;
• apply a first filter using a first UE identifier of the first UE, based on the association;
• forward the first service request from the first UE to a first core network based on the applied first filter;
• receive via a second base station, a second service request from a second user equipment (UE);
• apply a second filter using a second UE identifier of the second UE, based on the association;
• forward the second service request from the second UE to the second core network based on the applied second filter;
• and
• act as a gateway between at least one base station and one or more core networks,
• wherein the one or more core networks support at least two radio access technologies (RATs).
