Abstract: Aspects of the subject disclosure may include, for example, a method in which a processing system authenticates a communication device roaming from a home network that does not support Voice over Long Term Evolution (VoLTE) roaming, and in which the processing system communicates with a packet gateway (PGW) of an evolved packet core (EPC) separate from the processing system, to facilitate communication between the communication device and a subsystem of the EPC; the subsystem emulates the home network to provide a VoLTE roaming service to the communication device. The communication device also engages in a session initiation protocol (SIP) with the subsystem to initiate a communication session with the subsystem; in accordance with the communication session, the subsystem provides the VoLTE roaming service to the communication device. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, obtaining roaming agreement data related to roaming agreements that are between a wireless provider and a respective one of a plurality of wireless roaming providers; obtaining, for each wireless subscriber of the wireless provider, respective roaming usage data, all of the respective roaming usage data comprising collective roaming usage data; training, based upon the collective roaming usage data, a set of one or more models, the one or more models comprising one or more statistical models, one or more machine learning models, or any combination thereof, the one or more models being trained with multiple iterations of feedback loops, and the training resulting in one or more trained models; estimating for each wireless subscriber, based upon the one or more trained models, respective projected location information for a future time, all of the respective projected location information comprising collective projected location information; obtaining,
