1. A computer-implemented method for providing transference of a user equipment to a 5G network when a voice call is terminated, the computer-implemented method comprising:
determining, by a mobility management entity, whether the user equipment includes a 5G subscription based on a voice call termination message; and
based on the determining of whether the user equipment includes the 5G subscription, utilizing, by the mobility management entity, an unused bit of an evolved packet system radio access bearer message to initiate a handover of the user equipment to the 5G network.
