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, identifying a local mobile country code (MCC) for a wireless communication device, accessing a home MCC list for the wireless communication device, and determining whether the local MCC for the wireless communication device matches any home MCC comprised in the home MCC list for the wireless communication device. In various embodiments, an operating parameter of the wireless communication device may be modified responsive to a determination that the local MCC for the wireless communication device does not match any home MCC comprised in the home MCC list for the wireless communication device. Other embodiments are disclosed.

Abstract: Facilitating flexible maximum transmission unit packet core design in a communications network is provided herein. A system can comprise a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The operations can comprise receiving a first transmission unit setting from a first network device. The first transmission unit setting can indicate a size of a largest network layer protocol data unit that is able to be communicated in a single network transaction by the first network device. The operations can also comprise setting, at the device, a configuration of the first network device to the first transmission unit setting. Further, the operations can comprise sending first communication packets to the first network device using the first transmission unit setting and second communication packets to a second network device using a second transmission unit setting different from the first transmission unit setting.

Abstract: Aspects of the subject disclosure may include, for example, obtaining a message associated with a 5th Generation (5G) wireless service, the message containing: a first section including a service type identifier entry and a first timestamp that corresponds to the service type identifier entry; and a second section including a secondary radio access technology (RAT) entry, one or more data volume entries, and a second timestamp that corresponds to the secondary RAT entry and to the one or more data volume entries; matching the first timestamp and the second timestamp based upon a first value of the first timestamp equaling a second value of the second timestamp; and responsive to the matching of the first timestamp and the second timestamp, associating the service type identifier entry of the first section with the one or more data volume entries of the second section. Other embodiments are disclosed.

Abstract: Systems and methods for selectively disabling encryption for user equipment are disclosed. A technique comprises interrogating a location code of a device authenticated to a network through an encrypted connection and determining whether the location code corresponds to an unencrypted region. If the location code does not correspond to an unencrypted region, the technique comprises registering the device to the network for communication using the encrypted connection. If the location code corresponds to an unencrypted region, the technique comprises sending an intercept challenge to the device to re-authenticate the device to the network, the intercept challenge including parameters to establish an unencrypted connection, receiving re-registration information including unencrypted location information from the device using the unencrypted connection, and registering the device to the network using the unencrypted connection.
