Connecting user equipment to different core networks

A non-transitory computer-readable medium to cause one or more processors to execute processor-executable instructions, wherein the processor-executable instructions cause the one or more processors to:

• receive a request, originating from a user equipment (UE), to connect to a wireless telecommunication network that includes a plurality of core networks, the plurality of core networks associated with a single Public Land Mobile Network Identifier (PLMNID);
• determine an Access Point Name Identifier (APN ID) included in the request to connect, the APN ID identifying a network service accessible via a gateway device of a particular core network of the plurality of core networks;
• compare the APN ID included in the request to connect to an APN routing policy that defines associations between different APN IDs and each core network of the plurality of core networks;
• determine, based on the APN ID and the APN routing policy, a particular core network, of the plurality of core networks, for connecting the UE to the wireless telecommunication network;
• and
• establishing a connection between the UE and the particular core network by routing, based on the APN routing policy, the request to connect to an Mobility Management Entity (MME) of the particular core network.

A method, implemented by a network device, comprising:

• receiving, by the network device, a request, originating from a user equipment (UE), to connect to a wireless telecommunication network that includes a plurality of core networks, the plurality of core networks associated with a single Public Land Mobile Network Identifier (PLMNID);
• determining, by the network device, an Access Point Name Identifier (APN ID) included in the request to connect, the APN ID identifying a network service accessible via a gateway device of a particular core network of the plurality of core networks;
• comparing, by the network device, the APN ID included in the request to connect to an APN routing policy that defines associations between different APN IDs and each core network of the plurality of core networks;
• determining, by the network device and based on the APN ID and the APN routing policy, a particular core network, of the plurality of core networks, for connecting the UE to the wireless telecommunication network;
• and
• establishing, by the network device, a connection between the UE and the particular core network by routing, based on the APN routing policy, the request to connect to an Mobility Management Entity (MME) of the particular core network.
