Classification: CPC H | IPC H

Claim 0:
1. A system comprising:
at least one hardware processor; and
at least one non-transitory memory storing instructions, which, when executed by the at least one hardware processor, cause the system to:
receive a communication indicating a request by a mobile device to transfer from a communication session with an eNodeB (eNB) associated with a 4th Generation Long-Term Evolution (4G LTE) telecommunications network to a communication session with a gNodeB (gNB) associated with a 5th Generation New Radio (5G NR) telecommunications network,
wherein the mobile device is assigned an Internet protocol version 4 (IPv4) address to enable communications by the mobile device in a packet data network (PDN) session within the 4G LTE telecommunications network;

in response to the received communication, transmit a request for context of the mobile device to a mobility management entity (MME) associated with the 4G LTE network;
configure the gNB using the context of the mobile device; and
notify the mobile device that the PDN session associated with the IPv4 address has an inactive status,
wherein the notification causes the mobile device to initiate an Internet protocol version 6 (IPv6) PDN session with a core network associated with the 5G NR telecommunications network.
